    Hypertension remains uncontrolled in the majority of treated patients, especially those with multiple cardiovascular risk factors. This was demonstrated by a French study that showed that 70% of treated hypertensive patients are not controlled to the target level of 140/90 mmHg. This proportion reached 84% in hypertensive patients with diabetes (target level 130/85 mmHg). What are the reasons for this disappointing situation? Observational studies have shown that only a minority of patients with uncontrolled hypertension receive triple therapy including a diuretic. In this respect, self-measurement of blood pressure should improve the situation by allowing clinicians to base their decision to intensify hypertension treatment on more solid evidence than consultation blood pressure measurements alone. Patient-related factors may also contribute to this situation. Treated patients with uncontrolled hypertension often have multiple risk factors. This is associated with or is a source of poor treatment observance linked to patient psychological factors or a result of the increased consumption of medication. Finally, risk factors themselves may be responsible for problems with blood pressure control as a result of their detrimental effects on large arteries as well as the microvascular network. The early correction of such vascular anomalies is vital for medium and long-term blood pressure control.

  2. Hypertension in aging patients.

    Hypertension, especially isolated systolic hypertension, is commonly found in older (60-79 years of age) and elderly (≥80 years of age) people. Antihypertensive drug therapy should be considered in all aging hypertensive patients, as treatment greatly reduces cardiovascular events. Most classes of antihypertensive medications may be used as first-line treatment with the possible exception of α- and β-blockers. An initial blood pressure treatment goal is less than 140/90 mmHg in all older patients and less than 150/80 mmHg in the nonfrail elderly. The current paradigm of delaying therapeutic interventions until people are at moderate or high cardiovascular risk, a universal feature of hypertensive patients over 60 years of age, leads to vascular injury or disease that is only partially reversible with treatment. Future management will likely focus on intervening earlier to prevent accelerated vascular aging and irreversible arterial damage.

  3. Efficacy and safety of two fixed-dose combinations of S-amlodipine and telmisartan (CKD-828) versus S-amlodipine monotherapy in patients with hypertension inadequately controlled using S-amlodipine monotherapy: an 8-week, multicenter, randomized, double-blind, Phase III clinical study

    Purpose To evaluate the blood pressure (BP) lowering efficacy and safety of CKD-828, a fixed-dose combination of S-amlodipine (the more active isomer of amlodipine besylate, which is calcium channel blocker) and telmisartan (long acting angiotensin receptor blocker), in patients with hypertension inadequately controlled with S-amlodipine monotherapy. Patients and methods Eligible patients (N=187) who failed to respond after 4-week S-amlodipine 2.5 mg monotherapy (sitting diastolic blood pressure [sitDBP] ≥90 mmHg) to receive CKD-828 2.5/40 mg (n=63), CKD-828 2.5/80 mg (n=63), or S-amlodipine 2.5 mg (n=61) for 8 weeks. The primary efficacy endpoint, mean sitDBP change from baseline to Week 8, was compared between the combination (CKD-828 2.5/40 mg and CKD-828 2.5/80 mg) and S-amlodipine monotherapy groups. The safety was assessed based on adverse events, vital signs, and physical examination findings. Results After the 8-week treatment, changes in sitDBP/systolic BP (SBP) were −9.67±6.50/−12.89±11.78, −10.72±6.19/−13.79±9.41, and −4.93±7.26/−4.55±11.27 mmHg in the CKD-828 2.5/40 mg (P<0.0001/P<0.0001), CKD-828 2.5/80 mg (P<0.0001/P<0.0001), and S-amlodipine 2.5 mg (P<0.0001/P=0.0027) groups, respectively, which were all significant BP reductions. At Week 8, the CKD-828 2.5/40 mg (sitDBP/SBP: P=0.0002/P<0.0001) and CKD-828 2.5/80 mg (sitDBP/SBP: P=0.0001/P<0.0001) showed superior BP-lowering effects to S-amlodipine 2.5 mg (P<0.001). At Week 4, all groups showed significant antihypertensive effects but both CKD-828 combinations (CKD-828 2.5/40 mg and CKD-828 2.5/80 mg) exhibited superior BP-lowering effects to that of S-amlodipine 2.5 mg (sitDBP/SBP: P=0.0028/P=0.0001 and P<0.0001/P=0.0012, respectively). The adverse event incidence was significantly lower in the CKD-828 2.5/40 mg (9.52%, P=0.0086) than in the S-amlodipine 2.5 mg group (27.87%) and increasing the telmisartan dose induced no unexpected adverse events, suggesting the safety of CKD

    A study was made of the influence of the constant MKM2-1 magnets on patients suffering from essential hypertension. Continuous action of the magnetic field, created by such magnets, on the patients with stage II essential hypertension was noted to result in a decrease of arterial pressure without the occurrence of any side effects and in a simultaneous reduction of the scope of drug administration. Apart from that fact, magnetotherapy was discovered to produce a beneficial effect on the central hemodynamics and microcirculation. The use of the MKM2-1 magnets may be regarded as a feasible method of the treatment of essential hypertension patients at any medical institution.

    There is a known association between chemotherapy and radiotherapy for treatment of cancer patients and development or worsening of hypertension. The aim of this article is to review this association. A literature search was conducted for articles reporting this association on the databases PubMed, SciELO and LILACS between 1993 and 2013. There was a high coprevalence of hypertension and cancer, since both diseases share the same risk factors, such as sedentary lifestyle, obesity, smoking, unhealthy diet and alcohol abuse. The use of chemotherapy and adjuvant drugs effective in the treatment of cancer increased the survival rate of these patients and, consequently, increased the incidence of hypertension. We described the association between the use of angiogenesis inhibitors (bevacizumab, sorafenib and sunitinib), corticosteroids, erythropoietin and non-steroidal anti-inflammatory drugs with the development of hypertension. We also described the relationship between hypertension and carotid baroreceptor injury secondary to cervical radiotherapy. Morbidity and mortality increased in patients with cancer and hypertension without proper antihypertensive treatment. We concluded that there is need for early diagnosis, effective monitoring and treatment strategies for hypertension in cancer patients in order to reduce cardiovascular morbidity and mortality.

    Introduction: The most prevalent form of hypertension is systolic blood pressure (SBP) and it is considered to be predisposing risk factor for cardiovascular disease. The objective of the study was to assess self-care practices, knowledge and awareness of hypertension, especially related to SBP among cardiac hypertensive patients. Methodology: A Cross sectional study was conducted on 664 cardiac hypertensive patients, which were selected by non-probability convenience sampling from cardiology outpatient department of three tertiary care hospitals. Face to face interviews were conducted using a pre designed questionnaire. Data was entered and analyzed by SPSS (V17). Results: 81.8%, did not know that hypertension is defined as high blood pressure. 97.1% of the sample population did not know that top measurement of blood pressure was referred to as systolic and only 25.0% correctly recognized normal systolic blood pressure to be less than 140mmHg. 7.4% of the patients consulted their doctor for hypertension once or twice in a month. Risk factor for high blood pressure most commonly identified by the participants was too much salt intake Conclusions: The results state that there is an inadequate general knowledge of hypertension among cardiac patients and they do not recognise the significance of elevated SBP levels. There is a need to initiate programs that create community awareness regarding long term complications of uncontrolled hypertension, particularly elevated SBP levels so that there is an improvement in self-care practices of the cardiacpatients.

    The aim of this study was to investigate the blood viscosity profile and to evaluate the influence of plasmatic (fibrinogen) and cellular (erythrocyte aggregation) factors in a group of hypertensive patients, compared with a normotensive group. We worked with anticoagulated blood of both non diabetic hypertensive patients (n=31), and healthy individuals (n=40). The plasmatic viscosity and whole blood determination were obtained with a cone-plate viscometer. Erythrocyte aggregation was studied by microscopical observation and quantified by an Aggregate Shape Parameter (ASP), defined as the relation projected area/perimeter. Fibrinogen was determined by the Clauss method with a coagulometer. A comparison between these groups led us to assert that whole blood viscosity was significantly higher in hypertensive patients than in the controls at all shear rates. Plasma viscosity values only showed significant differences between both groups at low shear rate (1.15 a 11.56 seg(-1)). The hypertensive patients showed irregular and amorphous aggregates so that ASP appeared significantly higher (p< 0.001) in patients with hypertension (0.69 +/- 0.11) than in healthy subjects (0.25 +/- 0.12). Fibrinogen appeared slightly higher (p<0.01) in the hypertensive group than in the normal group. Several hemorheological parameters play important roles in the pathogenesis of hypertension. Among these factors, several hemorheological parameters could be altered in hypertension (hematocrit, plasma fibrinogen level, erythrocyte deformability and aggregability, plasma and whole blood viscosity). An increased RBC aggregation has been identified as an important factor responsible for disturbing blood rheological behavior in the microcirculation. The present study demonstrates an abnormal erythrocyte aggregation, which was detected by increased ASP values that could be responsible for vascular complications in hypertension.

    Objective To examine association between perceived inadequate staffing and musculoskeletal pain and to evaluate the role of work-related psychosocial and physical work factors in the association among hospital patient care workers. Methods A cross-sectional study was conducted among 1572 patient care workers in two academic hospitals. Perceived inadequate staffing was measured using the ‘staffing adequacy subscale’ of Nursing Work Index, which is a continuous scale that averages estimates of staffing adequacy by workers in the same units. Musculoskeletal pain (i.e. neck/shoulder, arm, low back, lower extremity, any musculoskeletal pain, and the number of area in pain) in the past 3 months was assessed using a self-reported Nordic questionnaire. Multilevel logistic regression was applied to examine associations between perceived inadequate staffing and musculoskeletal pain, considering clustering among the workers in the same units. Results We found significant associations of perceived inadequate staffing with back pain (OR: 1.50, 95% CI: 1.04, 2.15) and the number of body area in pain (OR: 1.42, 95% CI: 1.01, 2.00) after adjusting for confounders including work characteristics (job title, having a second job or not, day shift or not, and worked hours per week). When we additionally adjusted for physical work factors (i.e. use of a lifting device, and the amount of the time for each of five physical activities on the job), only the association between perceived inadequate staffing and back pain remained significant (OR: 1.50, 95% CI: 1.03, 2.19), whereas none of the associations was significant for all of musculoskeletal pains including back pain (OR: 0.92, 95% CI: 0.66, 1.41) when we additionally adjusted for work-related psychosocial factors (i.e. job demands, job control, supervisor support, and co-worker support) instead of physical work factors. Conclusions Perceived inadequate staffing may be associated with higher prevalence of back pain and work

    The effectiveness of exercise-treadmill testing in diagnosing coronary-artery disease in hypertensive patients is limited by a high rate of false positivity. Exercise radionuclide ventriculography, however, relies on different criteria (ejection fraction and wall motion), and we have evaluated this procedure in 37 hypertensive and 109 normotensive patients with chest pain, using coronary arteriography as an indicator of coronary disease. In the hypertensive cohort there was no difference in the ejection fraction at rest between the 17 patients with coronary disease and the 20 without it. Neither group had a significant mean (+/- S.E.M.) change in ejection fraction from rest to exercise (-1.9 +/- 2 and 1.4 +/- 1%, respectively). A wall-motion abnormality developed during exercise in 5 of the 17 hypertensive patients with coronary disease (29%) and in 4 of the 20 without it (20%) (P = not significant). In the normotensive cohort, however, the peak-exercise ejection fractions were significantly different. The 71 patients with coronary disease had a mean decrease of 3.6 +/- 1%, in contrast to the patients without coronary disease, who had an increase of +/- 1% (P < 0.001). An exercise-induced wall-motion abnormality was seen in 35 of the 71 patients with coronary disease (48%), as compared with 3 of the 38 without it (8%) (P < 0.001). We conclude that exercise radionuclide ventriculography is inadequate as a screening test for coronary atherosclerosis in hypertensive patients with chest pain. 28 references, 2 figures, 3 tables.

    Hypertension in renal transplant recipients is common and ranges from 50% to 80% in adult recipients and from 47% to 82% in pediatric recipients. Cardiovascular morbidity and mortality and shortened allograft survival are important consequences of inadequate control of hypertension. In this review, we examine the epidemiology, pathophysiology, and management considerations of post-transplant hypertension. Donor and recipient factors, acute and chronic allograft injury, and immunosuppressive medications may each explain some of the pathophysiology of post-transplant hypertension. As observed in other patient cohorts, renal artery stenosis and adrenal causes of hypertension may be important contributing factors. Notably, BP treatment goals for renal transplant recipients remain an enigma because there are no adequate randomized controlled trials to support a benefit from targeting lower BP levels on graft and patient survival. The potential for drug-drug interactions and altered pharmacokinetics and pharmacodynamics of the different antihypertensive medications need to be carefully considered. To date, no specific antihypertensive medications have been shown to be more effective than others at improving either patient or graft survival. Identifying the underlying pathophysiology and subsequent individualization of treatment goals are important for improving long-term patient and graft outcomes in these patients. PMID:25653099

    Pulmonary hypertension in end-stage renal disease patients is associated with significantly increased morbidity and mortality. The prevalence of pulmonary hypertension in dialysis patients is relatively high and varies in different studies from 17% to 49.53% depending on the mode of dialysis and other selection factors, such as the presence of other cardiovascular comorbidities. The etiopathogenic mechanisms that have been studied in relatively small studies mainly include arteriovenous fistula-induced increased cardiac output, which cannot be accomodated by, the spacious under normal conditions pulmonary circulation. Additionally, pulmonary vessels show signs of endothelial dysfunction, dysregulation of vascular tone due to an imbalance in vasoactive substances, and local as well as systemic inflammation. It is also believed that microbubbles escaping from the dialysis circuit can trigger vasoconstriction and vascular sclerosis. The non-specific therapeutic options that proved to be beneficial in pulmonary artery pressure reduction are endothelin inhibitors, phosphodiesterase inhibitor sildenafil, and vasodilatory prostaglandins in various forms. The specific modes of treatment are renal transplantation, size reduction or closure of high-flow arteriovenous fistulas, and transfer from hemodialysis to peritoneal dialysis-a modality that is associated with a lesser prevalence of pulmonary hypertension.

    For patients who are known to have an impaired immune system, bone healing is often impaired. Therefore, it has been suggested that an effectively functioning immune system will have an influence on the quality of bone healing. Here, we demonstrate that cells within the fracture hematoma of immunologically restricted patients (1) exhibit a disturbed osteogenic differentiation (normal SPP1 but diminished RUNX2 expression), (2) show a strong inflammatory reaction (high IL8 and CXCR4), and (3) react on local hypoxia (high expression of HIF1A) but with inadequate target gene responses (diminished LDHA and PGK1 expression). Thus, it is already within the early inflammatory phase of fracture healing that the local gene expression in fracture hematomas of immunologically restricted patients points toward a critical regeneration.

    Purpose: To evaluate the results of salvage radiotherapy (RT) after inadequate surgery in patients with invasive carcinoma of the cervix. Methods and Materials: Between 1996 and 2001, 105 invasive cervical carcinoma patients were treated at our center with external beam RT with or without intracavitary RT after having undergone total/subtotal hysterectomy at outside institutions. Results: The median follow-up was 34 months. The gap between surgery and RT was 23-198 days (median, 80). Clinically visible residual disease was present in 81 patients (77.1%). Total hysterectomy had been done in 82 patients (78%) and subtotal hysterectomy in 23 patients (22%). The 5-year overall survival, disease-free survival, and pelvic control rates of all patients were 55.2%, 53.3%, and 72.4%, respectively. On univariate analysis, older age, total hysterectomy, hemoglobin level >10 g% before RT, nonsquamous histologic type, use of intracavitary RT, a shorter gap between surgery and RT, and the absence of, or a small volume of, residual disease favorably affected the outcome. The 5-year actuarial rate of late toxicity (Radiation Therapy Oncology Group Criteria) was 19% in the rectum, 4.8% in the bladder, 24.8% in the skin, and 14.3% in the small intestine. Conclusions: Inadequate and inappropriate surgery in invasive cervical cancer with resulting gross residual disease is common in India. Factors such as the use of intracavitary RT, the correction of anemia, and a shorter gap between surgery and RT will enable postoperative RT to achieve acceptable results with minimal morbidity.

    To assess the potential effect of hypertension on the results of thallium-201 stress imaging in patients with chest pain, 272 thallium-201 stress tests performed in 133 hypertensive patients and 139 normotensive patients over a 1-year period were reviewed. Normotensive and hypertensive patients were similar in age, gender distribution, prevalence of cardiac risk factors (tobacco smoking, hyperlipidemia, and diabetes mellitus), medications, and clinical symptoms of coronary disease. Electrocardiographic criteria for left ventricular hypertrophy were present in 16 hypertensive patients. Stepwise probability analysis was used to determine the likelihood of coronary artery disease for each patient. In patients with mid to high likelihood of coronary disease (greater than 25% probability), abnormal thallium-201 stress images were present in 54 of 60 (90%) hypertensive patients compared with 51 of 64 (80%) normotensive patients. However, in 73 patients with a low likelihood of coronary disease (less than or equal to 25% probability), abnormal thallium-201 stress images were present in 21 patients (29%) of the hypertensive group compared with only 5 of 75 (7%) of the normotensive patients (p less than 0.001). These findings suggest that in patients with a mid to high likelihood of coronary artery disease, coexistent hypertension does not affect the results of thallium-201 exercise stress testing. However, in patients with a low likelihood of coronary artery disease, abnormal thallium-201 stress images are obtained more frequently in hypertensive patients than in normotensive patients.

    Hypertension causes a significant disease burden in all racial and ethnic groups and is directly attributable to excess weight in most cases. The relationship between increasing body mass index and hypertension prevalence has been recognized for decades. Epidemiologic studies clearly demonstrate the correlation between body weight and blood pressure in obese and lean populations. Most patients with hypertension are overweight or obese, and loss of excess weight lowers blood pressure. Although the epidemiologic relationship is clear, the understanding of mechanisms linking hypertension and weight gain is still evolving. Lifestyle modifications and specific pharmacologic agents address many of the known mechanisms; however, blood pressure remains difficult to control in obese hypertensive patients. This review highlights the association of obesity and hypertension, identifies potential mechanisms for this association, and describes nonpharmacologic and pharmacologic strategies that offer potential benefits for the obese patient with hypertension.

    Background. Central systolic blood pressure (CSBP) has prognostic significance and simplified devices for its estimation have been introduced recently. The aim of this study was to assess the achievement of the target CSBP in treated hypertensive patients. Subjects and Methods. One hundred patients with well-controlled hypertension were analysed. For CSBP estimation, we used the Arteriograph (TensioMed Ltd.), which uses one cuff for all measurements, the “single-point measurement” approach. Results. We found that 62% of patients had CSBP ≥ 130 mmHg, the suggested cut-off value for hypertension. When sex-specific classification was employed (CSBP ≥ 137 mmHg for female and CSBP ≥ 133 mmHg for male), only 13% of patients (mainly women) remained in the hypertensive range. We also found that 55% of patients had a CSBP higher than brachial pressure. Multiple analyses showed that CSBP was significantly associated with sex, height, and return time. Conclusions. A high proportion of treated hypertensive patients had CSBP levels that exceeded their brachial BP. CSBP positively correlated with lower height and shorter return time of the reflected pressure wave and was significantly higher in females compared to males. These findings suggest that, for CSBP classification, it is important to take height and sex-specific differences into account. PMID:28127560

    Adequate linezolid blood concentrations have been shown to be associated with an improved clinical outcome. Our goal was to assess new predictors of inadequate linezolid concentrations often observed in critically ill patients. Fifty-two critically ill patients with severe infections receiving standard dosing of linezolid participated in this prospective observational study. Serum samples (median, 32 per patient) were taken on four consecutive days, and total linezolid concentrations were quantified. Covariates influencing linezolid pharmacokinetics were identified by multivariate analysis and a population pharmacokinetic model. Target attainment (area under the concentration-time curve over 12 h [AUC12]/MIC ratio of >50; MIC = 2 mg/liter) was calculated for both the study patients and a simulated independent patient group (n = 67,000). Target attainment was observed for only 36% of the population on both days 1 and 4. Independent covariates related to significant decreases of linezolid concentrations included higher weight, creatinine clearance rates, and fibrinogen and antithrombin concentrations, lower concentrations of lactate, and the presence of acute respiratory distress syndrome (ARDS). Linezolid clearance was increased in ARDS patients (by 82%) and in patients with elevated fibrinogen or decreased lactate concentrations. In simulated patients, most covariates, including fibrinogen and lactate concentrations and weight, showed quantitatively minor effects on target attainment (difference of ≤9% between the first and fourth quartiles of the respective parameters). In contrast, the presence of ARDS had the strongest influence, with only ≤6% of simulated patients reaching this target. In conclusion, the presence of ARDS was identified as a new and strong predictor of insufficient linezolid concentrations, which might cause treatment failure. Insufficient concentrations might also be a major problem in patients with combined alterations of other covariate

    We attempted to identify the predictors of an inadequate hypoglycemia in insulin tolerance test (ITT), defined as a blood glucose level higher than 2.8 mmol/L after insulin injection, in Japanese patients with suspected or proven hypopituitarism. A total of 78 patients who had undergone ITT were divided into adequate and inadequate hypoglycemia groups. The relationships between the subjects' clinical parameters and inadequate hypoglycemia in ITT were analyzed. Stepwise logistic regression analysis identified high systolic blood pressure (SBP) and high homeostasis model assessment of insulin resistance (HOMA-IR) as being independent factors associated with inadequate hypoglycemia in ITT. Receiver operating characteristic (ROC) curve analysis revealed the cutoff value for inadequate hypoglycemia was 109 mmHg for SBP and 1.4 for HOMA-IR. The areas under ROC curve for SBP and HOMA-IR were 0.72 and 0.86, respectively. We confirmed that high values of SBP and HOMA-IR were associated with inadequate hypoglycemia in ITT, regardless of the degree of reduction of pituitary hormone levels. Furthermore, the strongest predictor of inadequate hypoglycemia was obtained by using the cutoff value of HOMA-IR. Our results suggest that HOMA-IR is a useful pre-screening tool for ITT in these populations.

  20. Hair transplantation in patients with inadequate head donor supply using nonhead hair: report of 3 cases.

    Follicular unit extraction is becoming an increasingly popular technique for hair transplantation, as it obviates the linear scarring associated with strip harvesting, and can provide highly presentable results. Using this technique, a few reports have described the small scale use of nonhead hair for head hair transplantation in men with inadequate head hair donor supply. In this report, 3 patients who were severely bald had hair transplanted from the chest, abdomen, legs, shoulders, or beard, as well as the head to achieve full coverage and excellent hairlines. Of the 3 cases, 2 had undergone previously unsuccessful hair transplant surgeries. Approximately 80% to 85% of the transplanted grafts survived. Although hair length and quality, surgery time, and the requirement for improved surgical skills remain challenges when using this technique, the sufficiently good outcomes from these selected candidates suggest that this technique may offer the possibility of restoring even severely bald states to normality in patients who would otherwise not be candidates for traditional hair transplantation surgery.

Methods The present study was a multicenter, randomized, active-controlled investigation comparing the effects of vildagliptin and pioglitazone in Korean patients receiving a stable dose of metformin but exhibiting inadequate glycemic control. Each patient underwent a 16-week treatment period with either vildagliptin or pioglitazone as an add-on treatment to metformin. Results The mean changes in HbA1c levels from baseline were –0.94% in the vildagliptin group and –0.6% in the pioglitazone group and the difference between the treatments was below the non-inferiority margin of 0.3%. The mean changes in postprandial plasma glucose (PPG) levels were –60.2 mg/dL in the vildagliptin group and –38.2 mg/dL in the pioglitazone group and these values significantly differed (P=0.040). There were significant decreases in the levels of total, low density lipoprotein, high density lipoprotein (HDL), and non-HDL cholesterol in the vildagliptin group but increases in the pioglitazone group. The mean change in body weight was –0.07 kg in the vildagliptin group and 0.69 kg in the pioglitazone group, which were also significantly different (P=0.002). Conclusion As an add-on to metformin, the efficacy of vildagliptin for the improvement of glycemic control is not inferior to that of pioglitazone in Korean patients with type 2 diabetes. In addition, add-on treatment with vildagliptin had beneficial effects on PPG levels, lipid profiles, and body weight compared to pioglitazone. PMID:27098505

    The Hypertension Attitude PersPEctives and Needs (HAPPEN) survey was a real-world survey of cardiologists, nephrologists, and patients with treated hypertension at level 3 hospitals in China. It aimed to characterize the attitudes and behavior of physicians and patients and to identify possible causes of poor blood pressure (BP) control. Randomly selected participants (100 cardiologists, 30 nephrologists, 400 patients) completed face-to-face interviews investigating BP control rates, consulting behavior, prescribing patterns, and attitudes toward hypertension management. Perceived levels of BP control were high; 70% of physicians and 85% of patients believed that BP targets were achieved, despite only 31% of patients achieving targets. Physician satisfaction with control rates and patient satisfaction with treatment were high. Differences in perceived and actual levels of BP control may be driving therapeutic inertia. In combination with inadequate patient evaluation and support services, therapeutic inertia may contribute to poor BP control among patients with treated hypertension in China.

    Previous studies have shown that in the population, only a minority of treated hypertensive patients achieve blood pressure (BP) control. Whether and to what extent this inadequate control has reflection on hypertension-related organ damage has never been systematically examined. In 2051 subjects belonging to the PAMELA (Pressioni Arteriose Monitorate E Loro Associazioni) Study population, we measured office, home, and 24-hour ambulatory BP values, together with echocardiographic left ventricular mass and wall thickness. Based on the fraction on antihypertensive treatment and on measurements of increased or normal office, home, or 24-hour ambulatory BP values, subjects were classified as normotensives, untreated hypertensives, treated hypertensives with inadequate BP control, and treated hypertensives with effective BP control. Compared with values in the normotensive group, left ventricular mass index, left ventricular wall thickness, and prevalence of left ventricular hypertrophy were markedly increased not only in untreated hypertensive patients but also in treated hypertensives with inadequate BP control. Echocardiographic abnormalities were less in treated hypertensives with BP control than in patients with inadequate BP control, but values were still clearly greater than in normotensive subjects. This was the case regardless whether BP control was assessed by office, home, and/or ambulatory values. Our data provide evidence that in the hypertensive fraction of the population, cardiac structural alterations can be frequently found in both the presence and absence of antihypertensive treatment. They also imply that even effective treatment of hypertension does not allow complete reversal of the cardiac organ damage characterizing high BP states.

    Resistant hypertension, the inability to achieve goal blood pressure despite the use of three or more appropriately dosed antihypertensive drugs (including a diuretic), remains a common clinical problem, especially in patients with chronic kidney disease (CKD). While the exact prevalence and prognosis of resistant hypertension in CKD patients remain unknown, resistant hypertension likely contributes significantly to increased cardiovascular risk and progression of kidney disease in this population. We review the identification and evaluation of patients with resistant hypertension, including the importance of 24-h ambulatory blood pressure monitoring in the identification of 'white-coat', 'masked' and 'non-dipper' hypertension, the latter of which has particular clinical and therapeutic importance in patients with resistant hypertension and CKD. We then discuss treatment strategies for resistant hypertension that target the pathophysiologic mechanisms underlying resistance to treatment, including persistent volume excess, incomplete renin-angiotensin-aldosterone system blockade and inadequate nocturnal blood pressure control. Finally, we propose a treatment algorithm for evaluation and treatment of resistant hypertension in patients with CKD.

    Hypertension is the leading cause of death worldwide. Globally and locally there has been an increase in hypertension in children, adolescents and young adults<40 years of age. In South Africa, the first decade of the millennium saw a doubling of the prevalence rate among adolescents and young adults aged 15-24 years. This increase suggests that an explosion of cerebrovascular disease, cardiovascular disease and chronic kidney disease can be expected in the forthcoming decades. A large part of the increased prevalence can be attributed to lifestyle factors such as diet and physical inactivity, which lead to overweight and obesity. The majority (>90%) of young patients will have essential or primary hypertension, while only a minority (<10%) will have secondary hypertension. We do not recommend an extensive workup for all newly diagnosed young hypertensives, as has been the practice in the past. We propose a rational approach that comprises a history to identify risk factors, an examination that establishes the presence of target-organ damage and identifies clues suggesting secondary hypertension, and a limited set of basic investigations. More specialised tests should be performed only where there is a clinical suspicion that a secondary cause for hypertension exists. There have been no randomised clinical trials on the treatment of hypertension in young patients. Expert opinion advises an initial emphasis on lifestyle modification. This can comprise a diet with reduced salt and refined carbohydrate intake, an exercise programme and management of substance abuse issues. Failure of lifestyle measures or the presence of target-organ damage should prompt the clinician to initiate pharmacotherapy. We recommend referral to a specialist practitioner in cases of resistant hypertension, where there is severe target-organ damage and when a secondary cause is suspected.

    Objective To evaluate effects of the anti-interleukin-6 receptor monoclonal antibody sarilumab administered with conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) on patient-reported outcomes (PROs) in the TARGET trial in patients with rheumatoid arthritis (RA) with inadequate response or intolerance to tumour necrosis factor inhibitors (TNF-IR). Methods 546 patients (81.9% female, mean age 52.9 years) were randomised to placebo, sarilumab 150 or 200 mg subcutaneously every 2 weeks + csDMARDs. PROs included patient global assessment (PtGA); pain and morning stiffness visual analogue scales; Health Assessment Questionnaire Disability Index (HAQ-DI); Short Form-36 Health Survey (SF-36); FACIT-Fatigue (FACIT-F); Work Productivity Survey-Rheumatoid Arthritis (WPS-RA) and Rheumatoid Arthritis Impact of Disease (RAID). Changes from baseline at weeks 12 and 24 were analysed using a mixed model for repeated measures; post hoc analyses included percentages of patients reporting improvements ≥ minimum clinically important differences (MCID) and scores ≥ normative values. Results Sarilumab + csDMARDs doses resulted in improvements from baseline at week 12 vs placebo + csDMARDs in PtGA, pain, HAQ-DI, SF-36 and FACIT-F that were maintained at week 24. Sarilumab improved morning stiffness and reduced the impact of RA on work, family, social/leisure activities participation (WPS-RA) and on patients' lives (RAID). Percentages of patients reporting improvements ≥MCID and ≥ normative scores were greater with sarilumab than placebo. Conclusions In patients with TNF-IR RA, 150 and 200 mg sarilumab + csDMARDs resulted in clinically meaningful patient-reported benefits on pain, fatigue, function, participation and health status at 12 and 24 weeks that exceeded placebo + csDMARDs, and were consistent with the clinical profile previously reported.

    The impact of the adequacy of empirical therapy on outcome for patients with bloodstream infections (BSI) is key for determining whether adequate empirical coverage should be prioritized over other, more conservative approaches. Recent systematic reviews outlined the need for new studies in the field, using improved methodologies. We assessed the impact of inadequate empirical treatment on the mortality of patients with BSI in the present-day context, incorporating recent methodological recommendations. A prospective multicenter cohort including all BSI episodes in adult patients was performed in 15 hospitals in Andalucía, Spain, over a 2-month period in 2006 to 2007. The main outcome variables were 14- and 30-day mortality. Adjusted analyses were performed by multivariate analysis and propensity score-based matching. Eight hundred one episodes were included. Inadequate empirical therapy was administered in 199 (24.8%) episodes; mortality at days 14 and 30 was 18.55% and 22.6%, respectively. After controlling for age, Charlson index, Pitt score, neutropenia, source, etiology, and presentation with severe sepsis or shock, inadequate empirical treatment was associated with increased mortality at days 14 and 30 (odds ratios [ORs], 2.12 and 1.56; 95% confidence intervals [95% CI], 1.34 to 3.34 and 1.01 to 2.40, respectively). The adjusted ORs after a propensity score-based matched analysis were 3.03 and 1.70 (95% CI, 1.60 to 5.74 and 0.98 to 2.98, respectively). In conclusion, inadequate empirical therapy is independently associated with increased mortality in patients with BSI. Programs to improve the quality of empirical therapy in patients with suspicion of BSI and optimization of definitive therapy should be implemented. PMID:22005999

    Voriconazole plasma concentrations (VPCs) vary widely, and concentrations outside the therapeutic range are associated with either worse outcome in invasive aspergillosis (IA) or increased toxicity. The primary goal of this cohort study conducted in a real-life setting was to identify potential factors associated with inadequate VPCs in ICU patients and patients with hematological malignancies. Within a period of 12 months, trough VPCs were obtained and analyzed with high-performance liquid chromatography, and the adequate range was defined as 1.5 to 5.5 mg/liter. VPCs of <1.5 mg/liter were defined as low, whereas VPCs of >5.5 mg/liter were defined as potentially toxic. A total of 221 trough VPCs were obtained in 61 patients receiving voriconazole, and 124/221 VPCs (56%) were found to be low. Multivariate analysis revealed that low VPCs were significantly associated with clinical failure of voriconazole, prophylactic use, younger age, underlying hematological malignancy, concomitant proton pump inhibitor (PPI) (pantoprazole was used in 88% of the patients), and absence of side effects. Low VPCs remained an independent predictor of clinical failure of voriconazole. The defined adequate range was reached in 79/221 (36%) VPCs. In 18 samples (8%), potentially toxic levels were measured. Multivariate analysis revealed higher body mass index (BMI), absence of hematological malignancy, therapeutic application, and diarrhea as factors associated with potentially toxic VPCs. Neurotoxic adverse events occurred in six patients and were mostly associated with VPCs in the upper quartile of our defined adequate range. In conclusion, potential factors like younger age, prophylaxis, underlying hematological malignancy, BMI, and concomitant PPI should be considered within the algorithm of voriconazole treatment.

    Objective: To assess the efficacy and safety of vildagliptin added to metformin in patients with type 2 diabetes mellitus (T2DM) inadequately controlled with metformin monotherapy. Methods: This was a 12-week prospective observational study where vildagliptin 50 mg twice daily was added to patients with T2DM inadequately controlled (glycosylated hemoglobin type A1c (Hba1c) 7-10%) by a daily dose of metformin ≥1700 mg between June 2012 and May 2013. Efficacy was assessed by change in Hba1c and fasting plasma glucose (FPG) levels, and safety was assessed by reported adverse events (AEs). Results: A total of 58 patients were enrolled in this study. Their age ranged between 39.0 and 71.0 years, with a mean of 52.6 years, and a standard deviation (SD) of 7.8. The average duration of diabetes mellitus (DM) was 4.0 years (SD 3.0) and half of the patients have had DM for more than three years. The mean baseline levels of Hba1c and FPG were 8% and 10.8 mmol/L, respectively. Patients treated with vildagliptin achieved clinically significant reductions in Hba1c of 1.1% (p value <.005) and reduction in FPG of 1.8 mmol/L (p value <.005) from baseline. Overall, 62.1% had achieved the target of Hba1c of <7% after vildagliptin use. Greater reductions in Hba1c were linked to higher baseline levels as well as to the daily frequency of metformin use. Mild AEs were reported by 16 patients. There was no incidence of hypoglycemia and there were no significant changes in body weight after treatment. Conclusions: Vildagliptin as add-on therapy to metformin improved glycemic control and was highly tolerable in T2DM patients who were inadequately controlled by metformin monotherapy.

    The present study investigated the effect of non-surgical periodontal treatment (SRP) on the composition of the subgingival microbiota of chronic periodontitis (CP) in individuals with type 2 diabetes (DM2) with inadequate metabolic control and in systemically healthy (SH) individuals. Forty individuals (20 DM2 and 20 SH) with CP underwent full-mouth periodontal examination. Subgingival plaque was sampled from 4 deep sites of each individual and tested for mean prevalence and counts of 45 bacterial taxa by the checkerboard method. Clinical and microbiological assessments were performed before and 3 months after SRP. At baseline, those in the DM2 group presented a significantly higher percentage of sites with visible plaque and bleeding on probing compared with those in the SH group (p<0.01). Those in the DM2 group presented significantly higher levels of C. rectus and P. gingivalis, and lower prevalence of P. micra and S. anginosus, compared with those in the SH group (p≤0.001). At the 3-month visit, both groups showed a significant improvement in all clinical parameters (p<0.01). Those in the DM2 group showed significantly higher prevalence and/or levels of A. gerencseriae, A. naeslundii I, A. oris, A. odontolyticus, C. sputigena, F. periodonticum, and G. morbillorum compared with those in the SH group (p≤0.001). However, those in the DM2 group showed a significant reduction in the levels of P. intermedia, P. gingivalis, T. forsythia, and T. denticola (p≤0.001) over time. Those in the SRP group showed improved periodontal status and reduced levels of putative periodontal pathogens at 3 months' evaluation compared with those in the DM2 group with inadequate metabolic control.

    Uncontrolled blood pressure (BP) remains a leading contributor to cardiovascular disease and mortality worldwide. Although current practice guidelines recommend treating patients with hypertension to defined BP goals, the approach is not widely implemented, and BP control in clinical practice is much worse than that attained in clinical trials. Recent and ongoing clinical trials are utilizing more aggressive approaches with combination therapy as initial treatment. This article discusses the problem of therapeutic or clinical inertia when attempting to control hypertension and highlights differences in BP control rates between clinical trials and real-world practice. Additionally, the rationale for an ongoing treat-to-goal study using a fixed-dose combination of amlodipine/olmesartan medoxomil in patients with hypertension not controlled on monotherapy is provided.

    Hypertension is a significant medical and public health issue which puts an enormous burden on health care resources and the community. It is a chronic medical condition in which the systemic arterial blood pressure (BP) is elevated. Serious complications including cardiovascular and cerebrovascular diseases would be preventable if the rise in BP with age could be prevented or diminished. The majority of hypertensive patients require long-term treatment. Oral antihypertensive drugs, lifestyle modification including exercise and dietary modification are milestones for hypertension therapy. However, the control rate of hypertension hasn't reached the expected requirements currently. "Three lows" status quo, just low awareness, low treatment, and low control, are still the major problems confronting modern medicine. Recently, uncontrolled factors of blood pressure are widely concerned, which include insomnia, constipation, mood disorders, exogenous, etc. What's more, the control strategies of hypertension should not only pay close attention to "patient's high blood pressure", but also to "hypertensive patient". Therefore, the treatment of uncontrolled factors of blood pressure plays an important role in hypertensive therapy, which could be further research priorities.

    We have studied ethical considerations of care among health professionals when treating and setting priorities for elderly patients in Norway. The views of medical doctors and nurses were analysed using qualitative methods. We conducted 21 in depth interviews and 3 focus group interviews in hospitals and general practices. Both doctors and nurses said they treated elderly patients different from younger patients, and often they were given lower priorities. Too little or too much treatment, in the sense of too many interventions and too much drugs, combined with too little care and comfort, was admitted as a relatively frequent yet unwanted consequence of the way clinical priorities were set for elderly patients. This was explained in terms of elderly patients not tolerating the same treatment as younger patients, and questions were raised about the quality of life of many elderly patients after treatment. These explanations were frequently referred to as medically sound decision making. Other explanations had little to do with medically sound decisions. These often included deep frustration with executive guidelines and budget constraints.

    Background Chronic kidney disease (CKD) knowledge among patients newly referred to a nephrology clinic is limited. This study aimed to determine if CKD knowledge 1 year after initial consultation in a nephrology clinic improves with standard care. Methods Patients newly referred to a nephrology outpatient clinic received standard care from nephrologists, and had access to educational pamphlets, relevant internet sites and patient support groups. Those with estimated glomerular filtration rate <20 mL/min/1.73 m2 received individual education from a multi-disciplinary team. Knowledge was assessed by questionnaire at first visit and after 12 months. Results Of 210 patients at baseline, follow-up data were available at 12.7 (±1.7) months for 95. Median age was 70 [interquartile range (IQR) 60–76] years and 54% were male. Baseline median creatinine of the follow-up cohort was 137 (IQR 99–179) µmol/L. Eighty per cent had seen a nephrologist at least three times, 8% saw a CKD nurse, 50% reported collecting pamphlets and 16% reported searching the internet. At 12 months, fewer patients reported being uncertain why they had been referred (5 versus 20%, P = 0.002) and fewer reported being unsure of the meaning of CKD (37 versus 57%, P = 0.005). Unknown (44%) and alcohol (23%) remained the most common causes of CKD identified. Fewer patients responded ‘unsure’ regarding the treatment of CKD (38 versus 57%, P = 0.004). Conclusions After a year of standard care at nephrology outpatient clinics there were some minor improvements in patient knowledge; however, patient understanding of CKD remained poor. PMID:26798471

    Detection of hypertension is traditionally a matter for the general practitioner, but an alternative detection scheme is home blood pressure measurement by patients, on patients' or doctors' decision. We designed and implemented a prototype software tool to provide information about hypertension, video instructions on correct home blood pressure measurement technique and a measurements diary. The system was developed using standard, software development methods and techniques. The program was developed for Danish-speaking patients. Usability (navigability, level and outcome of instructions, logical arrangement, level and focus of information, and program accessibility) was evaluated in a think-aloud test with test users performing specific, realistic tasks. The prototype provides written information about hypertension, written and video instructions on correct blood pressure measurement technique, and measurements diary functionality. All test users performed all tasks and rated navigability, level and outcome of instructions, logical arrangement, level and focus of information, and program accessibility high, and had positive attitudes towards the system. The components in the patient support tool can be used separately or in combination. The effects of video for home blood pressure measurement technique instruction remain unexplored.

    2010-03-01

    Pulmonary hypertension is a potentially lethal condition that may be encountered during the entire life span of patients with many forms of congenital or acquired heart disease, pulmonary disorders, and other diseases. Each pulmonary hypertensive patient requires anticipatory interventions geared to prevent severe exacerbations of the pulmonary hypertensive condition, promote pulmonary vasodilation, and optimize ventricular function. Patients with pulmonary hypertension are at higher risk for developing pulmonary hypertensive episodes in the immediate postoperative period after cardiac surgery, as well as during nonsurgical admissions. Nurses are in a critical position to provide anticipatory care to prevent the development of pulmonary hypertensive events. Nurses can be instrumental in optimizing outcomes for patients with pulmonary hypertension by providing immediate care upon the development of a pulmonary hypertension event and by monitoring ongoing responses to adjustments in therapeutic interventions.

    Hypertension is well known to one of the risk factors to reduce cognitive function, however, it is still unclear whether anti-hypertensive therapy is effective to prevent development of dementia or Alzheimer's disease. Epidemiological studies suggested antihypertensive therapy from the middle-age could reduce risk of dementia. The meta-analysis including HYVET also suggested blood pressure lowering from the elderly might be also effective to prevent development of dementia. The network meta-analysis and the cohort study using mega-data bank suggested ARB might be effective to prevent development of dementia or Alzheimer's disease compared to administration with other anti-hypertensive drugs. Although the further major clinical investigation is required, anti-hypertensive treatment might be useful to manage hypertensive patients with dementia.

    Background Baricitinib is an oral, reversible, selective Janus kinase 1 and 2 inhibitor. Methods In this phase III, double-blind 24-week study, 684 biologic disease-modifying antirheumatic drug (DMARD)-naïve patients with rheumatoid arthritis and inadequate response or intolerance to ≥1 conventional synthetic DMARDs were randomly assigned 1:1:1 to placebo or baricitinib (2 or 4 mg) once daily, stratified by region and the presence of joint erosions. Endpoint measures included American College of Rheumatology 20% response (ACR20, primary endpoint), Disease Activity Score (DAS28) and Simplified Disease Activity Index (SDAI) score ≤3.3. Results More patients achieved ACR20 response at week 12 with baricitinib 4 mg than with placebo (62% vs 39%, p≤0.001). Compared with placebo, statistically significant improvements in DAS28, SDAI remission, Health Assessment Questionnaire-Disability Index, morning joint stiffness, worst joint pain and worst tiredness were observed. In a supportive analysis, radiographic progression of structural joint damage at week 24 was reduced with baricitinib versus placebo. Rates of adverse events during the treatment period and serious adverse events (SAEs), including serious infections, were similar among groups (SAEs: 5% for baricitinib 4 mg and placebo). One patient had an adverse event of tuberculosis (baricitinib 4 mg); one patient had an adverse event of non-melanoma skin cancer (baricitinib 4 mg). Two deaths and three major adverse cardiovascular events occurred (placebo). Baricitinib was associated with a decrease in neutrophils and increases in low-density and high-density lipoprotein. Conclusions In patients with rheumatoid arthritis and an inadequate response or intolerance to conventional synthetic DMARDs, baricitinib was associated with clinical improvement and inhibition of progression of radiographic joint damage.

    Purpose Lymph node metastasis is an important factor for predicting the prognosis of colorectal cancer patients. However, approximately 60% of patients do not receive adequate lymph node evaluation (less than 12 lymph nodes). In this study, we identified a more effective tool for predicting the prognosis of patients who received inadequate lymph node evaluation. Materials and Methods The number of metastatic lymph nodes, total number of lymph nodes examined, number of negative metastatic lymph nodes (NL), lymph node ratio (LR), and the number of apical lymph nodes (APL) were examined, and the prognostic impact of these parameters was examined in patients with colorectal cancer who underwent surgery from January 2004 to December 2011. In total, 806 people were analyzed retrospectively. Results In comparison of different lymph node analysis methods for rectal cancer patients who did not receive adequate lymph node dissection, the LR showed a significant difference in overall survival (OS) and the APL predicted a significant difference in disease-free survival (DFS). In the case of colon cancer patients who did not receive adequate lymph node dissection, LR predicted a significant difference in DFS and OS, and the APL predicted a significant difference in DFS. Conclusion If patients did not receive adequate lymph node evaluation, the LR and NL were useful parameters to complement N stage for predicting OS in colon cancer, whereas LR was complementary for rectal cancer. The APL could be used for prediction of DFS in all patients. PMID:25943323

  1. New drugs and indications in 2010: inadequate assessment; patients at risk.

    PubMed

    2011-04-01

    In 2010, we rated 97 new drugs or new indications in our French edition la revue Prescrire, only 4 of which provided a therapeutic advantage. However, 19 others (1 in 5) were approved despite having more harms than benefits. More paediatric products were released in 2010 than in previous years, but few of them made any real difference and many had not been properly evaluated. Drug regulatory agencies can protect patients from exposure to dangerous drugs by refusing to grant market approval or by demanding their market withdrawal.Yet they are failing to fulfil this responsibility: so-called risk management plans and modifications to the wording in the SPC are only half-measures. Too often the authorities put companies' short-term financial interests above patients' well-being by granting premature marketing authorisation, by agreeing to high levels of reimbursement that fail to take added therapeutic value into account, and by allowing the development of "umbrella" ranges. The European authorities' questionable plans for pharmacovigilance and advertising of prescription-only drugs were restricted after public mobilisation, but they are still likely to undermine healthcare quality. Decision-makers must make patients' well-being their top priority.

    Objective. To evaluate the efficacy and tolerability of travoprost 0.004%/timolol 0.5% fixed-dose combination (TTFC) in patients with open-angle glaucoma (OAG) or ocular hypertension (OHT) inadequately controlled on beta-blocker monotherapy. Methods. In this phase IV, open-label study, 156 patients on beta-blocker monotherapy with mean intraocular pressure (IOP) between 18 and 32 mmHg were randomized (no washout period) to receive TTFC for 8 weeks (TTFC group) or to continue beta-blocker monotherapy for 4 weeks followed by TTFC for the remaining 4 weeks (beta-blocker group). Results. The mean IOP (±standard deviation) at baseline in the TTFC and beta-blocker groups was 22.5 ± 2.5 mmHg and 22.2 ± 2.3 mmHg, respectively, and at weeks 4 and 8, was 16.7 ± 3.1 mmHg and 16.1 ± 3.1 mmHg, respectively, in TTFC group and 21.1 ± 3.1 mmHg and 16.1 ± 2.8 mmHg, respectively, in the beta-blocker group. There was a significant least squares mean difference between TTFC and beta-blocker in 8 a.m. IOP at week 4 (−4.6 mmHg; one-sided 95% confidence interval [−inf, −3.9]; p < 0.0001 [primary endpoint]); the upper bound of the 95% confidence interval was within the prespecified limit (<0). Both treatments were well tolerated. Conclusion. Superior IOP control was achieved with TTFC in patients with OAG or OHT previously uncontrolled with beta-blockers. No new safety findings were identified. This trial is registered with ClinicalTrials.gov NCT02003391. PMID:28239491

    Hospital mortality rates are elevated in critically ill patients with bloodstream infections. Given that mortality may be even higher if appropriate treatment is delayed, we sought to determine the effect of inadequate initial empiric treatment on mortality in these patients. A retrospective cohort study was conducted across 13 intensive care units in Canada. We defined inadequate initial empiric treatment as not receiving at least one dose of an antimicrobial to which the causative pathogen(s) was susceptible within one day of initial blood culture. We evaluated the association between inadequate initial treatment and hospital mortality using a random effects multivariable logistic regression model. Among 1,190 patients (1,097 had bacteremia and 93 had candidemia), 476 (40%) died and 266 (22%) received inadequate initial treatment. Candidemic patients more often had inadequate initial empiric therapy (64.5% versus 18.8%), as well as longer delays to final culture results (4 vs 3 days) and appropriate therapy (2 vs 0 days). After adjustment, there was no detectable association between inadequate initial treatment and mortality among bacteremic patients (Odds Ratio (OR): 1.02, 95% Confidence Interval (CI) 0.70–1.48); however, candidemic patients receiving inadequate treatment had nearly three times the odds of death (OR: 2.89, 95% CI: 1.05–7.99). Inadequate initial empiric antimicrobial treatment was not associated with increased mortality in bacteremic patients, but was an important risk factor in the subgroup of candidemic patients. Further research is warranted to improve early diagnostic and risk prediction methods in candidemic patients. PMID:27152615

    We observed high incidence of anemia in patients with cerebral palsy sheltered in a specialized institution in Thessaloniki, Greece. Therefore, we decided to investigate its cause. We studied 108 patients, and assessed complete blood cell count, peripheral blood smear, serum iron, ferritin, folate, B12 and the presence of hemoglobin or parasites in the stools. In all cases, anemia was hypochromic and microcytic. Approximately 33% of patients suffered from hypochromic anemia, whereas 38% were iron deficient. There was no statistical difference in the incidence of iron deficiency between different age groups. All tests for fecal occult blood or intestinal parasites were negative. Folic acid and B12 levels were within normal range in all cases. We also found that 87 and 95.6% of patients on liquid diet were anemic and iron deficient, respectively, compared to only 18.8 and 22.3% of patients on normal diet. The high incidence of anemia was attributed to iron deficiency which was secondary to inadequate iron intake and decreased iron absorption. Thus, it would not be irrational to consider iron supplementation as the first measure in such patients and postpone endoscopic procedures for a later stage, unless there are clinical or laboratory findings (such as fecal occult blood) suggestive of gastrointestinal blood loss.

    Among patients on dialysis, hypertension is highly prevalent and contributes to the high burden of cardiovascular morbidity and mortality. Strict volume control via sodium restriction and probing of dry weight are first-line approaches for the treatment of hypertension in this population; however, antihypertensive drug therapy is often needed to control BP. Few trials compare head-to-head the superiority of one antihypertensive drug class over another with respect to improving BP control or altering cardiovascular outcomes; accordingly, selection of the appropriate antihypertensive regimen should be individualized. To individualize therapy, consideration should be given to intra- and interdialytic pharmacokinetics, effect on cardiovascular reflexes, ability to treat comorbid illnesses, and adverse effect profile. β-Blockers followed by dihydropyridine calcium-channel blockers are our first- and second-line choices for antihypertensive drug use. Angiotensin-converting enzyme inhibitors and angiotensin receptor blockers seem to be reasonable third-line choices, because the evidence base to support their use in patients on dialysis is sparse. Add-on therapy with mineralocorticoid receptor antagonists in specific subgroups of patients on dialysis (i.e., those with severe congestive heart failure) seems to be another promising option in anticipation of the ongoing trials evaluating their efficacy and safety. Adequately powered, multicenter, randomized trials evaluating hard cardiovascular end points are urgently warranted to elucidate the comparative effectiveness of antihypertensive drug classes in patients on dialysis. In this review, we provide an overview of the randomized evidence on pharmacotherapy of hypertension in patients on dialysis, and we conclude with suggestions for future research to address critical gaps in this important area.

    Background Systemic hypertension is highly prevalent and an important risk factor for cardiovascular events. Blood pressure control in hypertensive patients enrolled in the Hiperdia Program, a program of the Single Health System for the follow-up and monitoring of hypertensive patients, is still far below the desired level. Objective To describe the epidemiological profile and to assess blood pressure control of patients enrolled in Hiperdia, in the city of Novo Hamburgo (State of Rio Grande do Sul, Brazil). Methods Cross-sectional study with a stratified cluster random sample, including 383 adults enrolled in the Hiperdia Program of the 15 Basic Health Units of the city of Porto Alegre, conducted between 2010 and 2011. Controlled blood pressure was defined as ≤140 mmHg × 90 mmHg. The hypertensive patients were interviewed and their blood pressure was measured using a calibrated aneroid device. Prevalence ratios (PR) with 95% confidence interval, Wald's χ2 test, and simple and multiple Poisson regression were used in the statistical analysis. Results The mean age was 63 ± 10 years, and most of the patients were females belonging to social class C, with a low level of education, a sedentary lifestyle, and family history positive for systemic hypertension. Diabetes mellitus (DM) was observed in 31%; adherence to the antihypertensive treatment in 54.3%; and 33.7% had their blood pressure controlled. DM was strongly associated with inadequate BP control, with only 15.7% of the diabetics showing BP considered as controlled. Conclusion Even for hypertensive patients enrolled in the Hiperdia Program, BP control is not satisfactorily reached or sustained. Diabetic hypertensive patients show the most inappropriate BP control. PMID:25004419

    Background Treatment options for patients with opioid-induced constipation (OIC) and inadequate response to laxatives (LIR) are few. Objective Assess the efficacy and safety of orally administered naloxegol in patients with prospectively confirmed OIC and LIR Methods We analyzed pooled data from two identical randomized, double-blind, placebo-controlled, Phase 3 trials of naloxegol in patients with non-cancer pain, OIC and LIR in which naloxegol (12.5 mg, n = 240; 25 mg, n = 241) or placebo (n = 239) were administered daily. We assessed the response rates, time to first post-dose laxation, spontaneous bowel movements (SBMs), OIC symptoms and patient-reported outcomes over 12 weeks. Results OIC response rates for the naloxegol 25-mg (p < 0.001) and the 12.5-mg (p = 0.005) LIR dose groups were higher than placebo. Median times to first post-dose SBM were 7.6, 19.2 and 41.1 hours for the naloxegol 25 mg, naloxegol 12.5 mg and placebo groups, respectively. Other SBM measures, daily symptoms of OIC, and both the Patient Assessment of Constipation - Symptoms and Patient Assessment of Constipation-Quality of Life scores improved from baseline with naloxegol treatment. Changes from baseline in opioid dose, pain scores and opioid withdrawal scores were similar among treatment groups. Conclusions Naloxegol was efficacious, generally safe and well tolerated in the patients with OIC and LIR, while preserving opioid analgesia.

    We have studied glucose tolerance under carefully controlled conditions in 79 patients with arterial hypertension. The results show that, in patients with arterial hypertension but without clinical diabetes mellitus, the glucose tolerance was abnormal in 77.3% and normal in 22.3%. The corresponding figure in the control group of normotensive subjects was 0%. In each test the responses to glucose administration were analyzed by plotting the logarithm of the blood glucose concentration against time. For the points between 60 and 120 min, corresponding to the periods following glucose administration, a linear relationship was obtained and showed a decline at an exponential rate, as noted by other observers. An estimate of the volume of distribution of glucose was obtained as follows. Values observed in hypertensives with a pathological percent fall in blood glucose per minute (Kg) were 29.8 +/- 12.0 (mean +/- SD) liters and those in normal subjects with normal Kg values had a mean of 14.35 +/- 2.98, the difference being highly significant (p less than 0.0001). The results of the theoretical glucose concentration are also presented. Those obtained from subjects with normal Kg values (359.0 +/- 58.4 mg/dl) are significantly higher than in subjects with pathological Kg values (257.6 +/- 51.3 mg/dl; p less than 0.0001). All patients with either pathological or normal Kg values had normal glucose concentration levels, fasting blood sugar and no glucose in the urine specimen. The difference between pathological Kg values (107.0 +/- 25.8 mg/dl) and normal Kg values (90.6 +/- 13.0 mg/dl) was not found to be statistically different (p greater than 0.05). The distribution and means of glucose half time in controls with normal Kg values and hypertensives with pathological Kg values were: 63.5 +/- 11.5 and 137.8 +/- 48.1 min, respectively. The difference between normal and pathological Kg values being statistically significant at a confidence level above 99.5%. We also studied

    Objective: To evaluate the effects of ticagrelor and high-dose clopidogrel on the platelet functions in patients with inadequate response to clopidogrel. Methods: In this prospective, randomized and controlled study, patients who had been diagnosed as acute coronary syndrome (ACS) with inadequate response to clopidogrel in the Second Hospital of Hebei Medical University from July 2015 to June 2016 were enrolled. Inadequate response to clopidogrel was defined as absolute reduction of platelet aggregation rate (PAR) <30% or PAR >70%. Eligible patients were randomly assigned to two groups, the high-dose group and the ticagrelor group. Clinical information and intervention protocols were compared. The PAR of the two groups were measured at the time of baseline, the 24th hour, 72nd hour, and the 7th day after treatments, the other platelet-related parameters were measured including platelet count (PLT), mean platelet volume (MPV), platelet distribution width (PDW) at the same time points. Besides, the markers of platelet activation human P-selectin (CD62P) and thromboxane A2 (TXA2) were also recorded to compare. The incidence of major adverse cardiac events (MACE) and the side effects between two groups were followed up for three months. Results: A total of 74 patients were finally enrolled, 38 of whom were assigned to the ticagrelor group and the rest of them to the high-dose clopidogrel group. The baseline clinical and procedural characterists were similar. There were no significant differences in baseline levels of PAR between the two groups [(79.38±11.20)% vs. (73.97±12.74)%, P>0.05]. For both groups, the levels of PAR significantly decreased at each time point (P<0.001). Besides, the levels of PAR in ticagrelor group were lower than those in high-dose clopidogrel group at the 24th hour, 72nd hour and 7th day after treatments: [(25.92±10.31)% vs. (37.95±11.63)%, P<0.001], [(28.02±14.61)% vs. (30.64±10.73)%, P<0.001], [(37.17±11.11)% vs. (36.80±7.26)%, P<0

    Cerebrospinal fluid flow (CSF) was studied using isotope cisternography in 52 patients with increased intracranial pressure (ICP), all of whom showed acute transient rises of ICP, i.e., plateau waves, in their continuous ICP recordings. The patients were assigned to two groups. Group I was comprised of 23 patients without hydrocephalus and high ICP resulting from brain tumors, benign intracranial hypertension, and superior sagittal sinus thrombosis. Group II included 29 patients with either communicating hydrocephalus or high ICP resulting from rupture of intracranial aneurysm. Plateau waves were frequently observed in patients with baseline pressures ranging from 21 to 40 mmHg in both groups. The isotope cisternographic pattern in the Group I patients showed a large accumulation of radioactivity over the cerebral convexities, while that in the Group II patients revealed a complete obstruction of the subarachnoid space over both cerebral convexities. The isotope clearance from the intracranial CSF showed a marked delay in both groups of patients with one exception. The results suggest that, in the limited range of increased ICP caused by delayed CSF absorption, plateau waves are most evident regardless of the isotope cisternographic pattern.

    Objective To assess joint disease activity by ultrasound (US) in patients with rheumatoid arthritis (RA) initiating treatment with adalimumab (ADA) plus methotrexate (MTX). Methods Data for this post hoc analysis originated from the MUSICA trial (ClinicalTrials.gov identifier: NCT01185288), which evaluated the efficacy of initiating ADA (40 mg every other week) plus 7.5 or 20 mg/week MTX in 309 patients with RA with an inadequate response to MTX. Synovial vascularization over 24 weeks was assessed bilaterally at metacarpophalangeal joint 2 (MCP2), MCP3, MCP5, metatarsophalangeal joint 5, and the wrists by power Doppler US (PDUS). A semiquantitative 4‐grade scale was used. Disease activity was assessed using the Disease Activity Score in 28 joints using the C‐reactive protein level (DAS28‐CRP) and Simplified Disease Activity Index (SDAI). The correlation between continuous variables was assessed using Pearson's correlation coefficient. Results After 24 weeks of treatment with ADA plus MTX, rapid improvements in the mean synovial vascularity score were observed; the greatest improvements were in MCP2 (−0.5), MCP3 (−0.4), and the wrist (−0.4). At week 24, patients with the lowest DAS28‐CRP (<2.6) had the lowest mean 5‐joint and 3‐joint composite synovial vascularity scores. The 5‐joint and 3‐joint scores were strongly correlated (ρ > 0.9). Synovial vascularity scores correlated poorly with DAS28, swollen joint count in 66 joints (SJC66), SJC28, tender joint count in 68 joints (TJC68), TJC28, Clinical Disease Activity Index (CDAI), SDAI, physician's global assessment, patient's global assessment of pain, and disease duration (ρ < 0.2). Thirty‐two (70%) of 46 patients with a DAS28‐CRP of <2.6, and 11 (58%) of 19 patients with an SDAI indicating remission had at least 1 joint with a synovial vascularity score of ≥1. Conclusion PDUS detects changes in synovial vascularity in RA patients treated with ADA plus MTX, and residual synovial

    1. Blood pressure, glomerular filtration rate (GFR) and renal plasma flow (RPF) were measured in twenty-three patients with essential hypertension and in twenty-one control subjects. Plasma renin concentration was measured in all the hypertensive patients and in fifteen control subjects. 2. GFR and RPF were similar in the hypertensive group and in the control group, whereas the renal vascular resistance was significantly higher in the hypertensive patients. GFR and RPF decreased with increasing blood pressure in both groups. Increasing age induced a further reduction in GFR and RPF in the control subjects but not in the hypertensive patients. 3. Plasma renin concentration in the hypertensive group did not differ from that in the control subjects. The concentration was not correlated to age in either the hypertensive or normal group. 4. Plasma renin index was positively correlated to GFR and RPF and inversely correlated to filtration fraction and renal vascular resistance. 5. It is concluded that GFR and RPF depend on blood pressure in both hypertensive patients and normotensive control subjects. In contrast to the control group, the age effect was negligible in the hypertensive group. It is suggested that renin release depends on changes in renal vascular resistance in the arterioles at the glomerulus and the results support the baroreceptor theory of renin release.

    We have found an appreciable number of pheochromocytomas in patients with neurofibromatosis and concurrent hypertension (ten of 18 cases). At diagnosis, the patient age range was 15 to 62 years, the clinical appearance of the neurofibromatosis did not predict who would and who would not have pheochromocytomas, but the age at diagnosis was helpful in that our younger patients tended to have causes of hypertension other than pheochromocytoma. However, several causes of hypertension may coexist. The biochemical findings were highly diagnostic. The pheochromocytomas secreted epinephrine as well as norepinephrine and resided in or next to the adrenal gland. Where pheochromocytoma is the cause of hypertension, its resection generally results in a better control of hypertension than that obtained in patients whose BPs were elevated from other unknown causes.

    Abstract Background: To observe the effect of alogliptin combined with metformin on pulmonary function in obese patients with type 2 diabetes inadequately controlled by metformin monotherapy (500 mg, bid po, for at least 3 months), and evaluate its efficacy and safety. Methods: After a 2-week screening period, adult patients (aged 36–72 years) entered a 4-week run-in/stabilization period. Then, patients were randomly assigned to either the intervention group (n = 55) or the control group (n = 50) for 26 weeks. The patients in the control group were given metformin (1000 mg, bid po) and the patients in the intervention group were given metformin (500 mg, bid po) combined with alogliptin (25 mg, qd po). All the patients received counseling about diet and exercise from a nutritionist during run-in and treatment periods. The primary endpoints were the between-group differences in the changes in pulmonary function parameters (vital capacity [VC]%, forced vital capacity [FVC]%, forced expiratory volume in 1 second (FEV1)%, peak expiratory force [PEF]%, maximal voluntary ventilation [MVV]%, total lung capacity [TLC%], forced expiratory volume in 1 second/forced vital capacity [FEV1/FVC%], diffusing capacity for carbon monoxide of lung [DLCO]%, and diffusing capacity for carbon monoxide of lung/unit volume [DLCO/VA%]) between pretherapy and posttreatment. The secondary endpoints were changes from baseline to week 26 in glycosylated hemoglobinA1c (HbA1c), FPG, 2hPG, homeostasis model assessment insulin resistance (HOMA-IR), waist circumference (WC), and BMI. The tertiary endpoints were the changes from baseline to week 26 in blood-fat (total cholesterol [TC], high-density lipoprotein cholesterol [HDL-C], low-density lipoprotein cholesterol [LDL-C], and triglycerides [TG]). The quartus endpoints were the changes from baseline to week 26 in systolic blood pressure (SBP) and diastolic blood pressure (DBP). The 5th endpoints were the changes from baseline to week 26

    Objective Adults with hypothalamic‐pituitary disease have increased morbidity and mortality from cardiovascular disease (CVD). Therefore, the prevalence of CVD and adequacy of treatment of cardiovascular risk factors (according to current treatment guidelines) was studied in a large group of patients with hypothalamic‐pituitary disease. Study design In 2005, 152 consecutive adult patients with hypothalamic‐pituitary disease attending our neuro‐endocrine centre were clinically examined and blood pressure (BP), lipid profile, type 2 diabetes mellitus, body composition and smoking status were assessed. Results Of the 152 patients, 36.8% had treated hypertension and 28.2% had treated dyslipidaemia. Many of these patients had inadequate BP control (BP >140/85 mm Hg, 44.6%) and undesirable lipid levels (total cholesterol >4.0 mmol/l, 69%). Also, many of the untreated patients had BP and lipid levels which should have been considered for treatment (26 patients (27%) and 83 patients (76%), respectively). Smoking was admitted in 18% of patients. Central adiposity was present in 86% and obesity (body mass index ⩾30) was present in 50%. Conclusions Cardiovascular risk factors are highly prevalent and often inadequately treated in adult patients with hypothalamic‐pituitary disease. Aggressive treatment of these factors is essential to reduce mortality and morbidity from CVD in these patients. PMID:17403957

    Arterial hypertension represents a risk factor for cerebrovascular disease. It has been hypothesized that chronic hypertension may eventually result in small subcortical infarcts associated with some cognitive impairments. One hundred fourteen patients with primary systemic hypertension (PSH) and 114 matched subjects were selected. PSH patients were further divided in four groups depending upon the hypertension severity. In addition to the medical and laboratory exams, a neuropsychological evaluation was administered. The NEUROPSI neuropsychological test battery was used. An association between level of hypertension and cognitive impairment was observed. Most significant differences were observed in the following domains: Reading, executive functioning, constructional, and memory-recall. No differences were observed in orientation, memory-recognition, and language. Some neuropsychological functions appeared impaired even in the PSH group with the least risk factors. Cognitive evaluation may be important in cases of PSH not only to determine early subtle cognitive changes, but also for follow-up purposes, and to assess the efficacy of different therapeutic procedures.

    Hypertension is a chronic illness affecting more than a billion people worldwide. The high prevalence of the disease among the American population is concerning and must be considered when treating dental patients. Its lack of symptoms until more serious problems occur makes the disease deadly. Dental practitioners can often be on the frontlines of prevention of hypertension by evaluating preoperative blood pressure readings, performing risk assessments, and knowing when to consider medical consultation of a hypertensive patient in a dental setting. In addition, routine follow-up appointments and patients seen on an emergent basis, who may otherwise not be seen routinely, allow the oral health provider an opportunity to diagnose and refer for any unknown disease. It is imperative to understand the risk factors that may predispose patients to hypertension and to be able to educate them about their condition. Most importantly, the oral health care provider is in a pivotal position to play an active role in the management of patients presenting with a history of hypertension because many antihypertensive agents interact with pharmacologic agents used in the dental practice. The purpose of this review is to provide strategies for managing and preventing complications when treating the patient with hypertension who presents to the dental office. PMID:27799823

    Hypertension is a major cardiovascular (CV) risk factor and is predicted by heightened CV reactivity to stress in healthy individuals. Patients with hypertension also show an altered stress response, while insecure attachment is linked to a heightened stress reactivity as well. This is the first study aiming to assess attachment representations in patients with primary hypertension and to investigate their CV responses when their attachment system is activated. We studied 50 patients (38 men, 12 women) with primary hypertension. The Adult Attachment Projective Picture System (AAP), a widely used and validated interview, was performed to measure the patients' attachment representations, and to activate their attachment system. Blood pressure and heart rate were measured after 10 min at rest prior to and directly after the AAP interview. Mood and state anxiety were assessed using the Multidimensional Mood State Questionnaire (MDBF) and the State Trait Anxiety Inventory-State (STAI-S) before and after the experiment. The prevalence of insecure attachment (dismissing, preoccupied, unresolved) in hypertensive patients was predominant (88%), while in non-clinical populations, only about 50% of individuals had insecure attachment patterns. Blood pressure (p < 0.001), heart rate (p = 0.016), and rate pressure product (p < 0.001) significantly increased in response to the attachment interview. Secure attached patients showed the highest rise in systolic blood pressure (p = 0.020) and the lowest heart rate compared to the other attachment groups (p = 0.043). However, attachment representation showed no significant group or interaction effects on diastolic blood pressure (DBP) and rate pressure product. Insecure attachment was highly over-represented in our sample of patients with primary hypertension. Additionally, a robust CV response to the attachment-activating stimulus was observed. Our data suggest that insecure attachment is significantly linked to primary hypertension

    Objectives The aim of this longitudinal, open-label, comparative, multicenter study was to assess cognitive function in hypertensive patients receiving mid-term treatment with lercanidipine. Methods Hypertensive patients aged 40 years or older were treated with lercanidipine (10mg daily) after 7–10 days washout period. The duration of the study was 6 months. Blood pressure (BP) was measured every 4 weeks (JNC 6th report). In patients with inadequate BP control, doxazosin was added and up-titrated. At baseline and after 6 months of treatment, cognitive function was evaluated using the Spanish validated version of the Mini-Mental State Examination (MMSE) and the Trail Making Test (TMT). Results In the study population of 467 patients, BP decreased from 154.4/95.3 mmHg at baseline to 134.8/80.7 mmHg at 6 months. At the end of the study, 98% of patients were receiving lercanidipine, 20% an angiotensin-converting enzyme inhibitor, and 6% doxazosin. Adequate BP control was obtained in 68% of patients. The mean (standard deviation) MMSE scores improved from 32.35 (2.59) to 33.25 (2.36) (p<0.0001). Patients with good BP control scored significantly better than those with inadequate BP control (p<0.05), which was already observed at the first month. Conclusions The third-generation calcium channel antagonist, lercanidipine, improved cognitive function after 6 months of treatment especially in patients with good BP control, suggesting that improvements in cognitive function may be associated with a decrease in BP.

    Twenty-four hour urinary excretion of albumin (UEalb), IgG and beta-2 microglobulin was investigated at a 3 hour-interval in a control group (C) of healthy subjects, in 30 patients with renovascular hypertension (RVH), and in 16 patients with essential hypertension (EH). Mean UEalb in RVH was significantly higher than in C. A significant direct correlation was demonstrated between diastolic blood pressure and UEalb (p < 0.01). Microalbuminuria (MA) > or = 30 micrograms.min-1 was found in about 18% of RVH patients; it was higher than 16.7 micrograms.min-1 in approx. 31%. These results did not substantially differ from those obtained in patients with EH. The cause for increased UEalb in hypertensive patients may be functional, haemodynamic changes, or structural ones. In either case, MA indicates renal injury, and these patients should be given increased attention when monitoring their blood pressure and when selecting antihypertensive drugs.

    Purpose Red cell distribution width (RDW), expressed in femtoliters (fl), is a measure of the variation in the size of circulating erythrocytes and is often expressed as a direct measurement of the width of the distribution. We aim to observe the mean value of red cell distribution width (RDW) in hypertensive patients. Increased RDW can be used as a tool for early diagnosis, as an inflammatory marker, and a mortality indicator in hypertensive patients due to its close relation to inflammation. Materials and methodology Hypertensive patients who had the condition for more than one year duration, diagnosed according to the Joint National Committee (JNC 7) criteria were subjected to complete blood count and RDW measurement. One hundred patients, aged between 12 years and 65 years were enrolled from the outpatient department of medicine at the Military Hospital Rawalpindi. Results The mean age (± SD) of the patients was 51.48 ± 10.08 years. Out of 100 patients 69% were males whereas 31% were females. The overall frequency of hypertension more than five years was 55% subjects whereas 45% individuals had duration of hypertension less than five years. Mean RDW in females was found to be 49.35±8.42 fl while mean RDW in males was 44.78±7.11 fl. An independent sample t-test was applied to assess if there was any significant difference between age and gender. No significant difference between age and gender was found (p<0.05). The Mann-Whitney test was used to assess any association of RDW with gender. RDW values in females was found to be statistically significantly higher than in males (U=603, p=0.01). Linear regression showed that mean RDW value increased with increasing age (P <0.001). Conclusions A significant number of patients with hypertension have increased levels of RDW. Therefore, it is recommended that serum RDW should be checked regularly in patients with hypertension. PMID:28070471

    Although primary (essential) hypertension is detectable in childhood, secondary causes of hypertension must be considered in evaluating and managing hypertension in children and adolescents. Very young children and children with severe hypertension may have an underlying cause of the hypertension. Interventions to control elevated blood pressure (BP) are clinically important for all children with high BP. Nonpharmacologic approaches are recommended for all asymptomatic children with hypertension and prehypertension. Some children and adolescents will require pharmacologic therapy to control BP and to optimize organ protection. Recent advancements in pediatric clinical trials of antihypertensive agents have provided data on BP-lowering effects and safety in children. Little has been published on the choice and use of various classes of antihypertensive drugs for management of secondary hypertension in children and adolescents. This review focuses on the clinical management of specific types of secondary hypertension in pediatric patients.

    Context: Drug-drug interactions(DDIs) are significant but avoidable causes of iatrogenic morbidity and hospital admission. Aim: To detect potential drug-drug interactions among medications received by hypertensive patients. Materials and Methods: Patients of both sex and all adult age groups, who were attending medicine out -patient department (OPD) of a tertiary care teaching rural hospital since last six months and were being prescribed antihypertensive drug/s for essential hypertension, were selected for the study. Hypertensive patient with co-morbities diabetes mellitus, ischemic heart diseases, congestive heart failure, and chronic renal diseases were also included in the study. Potential drug drug interactions were checked with medscape drug interaction software. Results: With the help of medscape drug interaction software, 71.50% prescriptions were identified having atleast one drug-drug interaction. Total 918 DDIs were found in between 58 drug pairs. 55.23% DDIs were pharmacodynamic, 4.79% pharmacokinetic type of DDIs. 32.24% DDIs were found affecting serum potassium level. 95.42% DDIs were found significant type of DDIs. Drug drug interaction between atenolol & amlodipine was the most common DDI (136) followed by metoprolol and amlodine (88) in this study. Atenolol and amlodipine ( 25.92%) was the most common drugs to cause DDIs in our study. Conclusion: We detected a significant number of drug drug interaction in hypertensive patients. These interactions were between antihypertensive agents or between hypertensive and drug for co-morbid condition. PMID:25584241

    We explored the influence of antidepressant therapy on blood pressure and quality of life in elderly patients with hypertension. Depression occurs at a higher rate in patients with hypertension than in the normal population. It has been reported that depressive symptoms lead to poorer hypertension control, resulting in the development of complications. We conducted a randomized, parallel group study. A total of 70 elderly patients with hypertension in the period of August 2008 to March 2011 were divided into two groups based on their antihypertensive therapy, a control group (amlodipine, 5 mg daily; n=35) and a therapy group (amlodipine, 5mg daily; citalopram, 20 mg daily; n=35). We compared 24 hour, daytime, and nighttime measurements of systolic and diastolic blood pressure, in addition to quality of life, assessed using the Hamilton rating scale for depression, and a 36 item Short Form quality of life questionnaire (SF-36). Both groups were followed for 3 months. At the end of 3 months, all blood pressure levels were significantly lower in the therapy group than in the control group. The other scores (with the exception of the physical function subcategory of the SF-36 quality of life scale) were significantly higher. Our study indicates that clinicians should be aware of depressive symptoms in elderly patients with hypertension, and should consider antidepressant therapy in these patients.

    Background The prevalence and clinical significance of white-coat hypertension (WCHT) and masked hypertension (MHT) are unknown in Koreans. Here we measure the frequency of WCHT and MHT in hypertensive subjects and identify the epidemiologic and/or clinical factors that predict it in Korean subjects. Methods This study is a retrospective analysis of a random sample from February 2004 to October 2005. All patients had measurements of blood pressure (BP) in the clinic and 24-hour ambulatory blood pressure monitoring (ABPM). Subjects were classified into four groups on the basis of daytime ambulatory BP and clinic BP level: 1) Normotension (NT), 2) MHT, 3) WCHT, and 4) sustained hypertension (SHT). Results For all 967 patients, the mean clinic BP was 157.7±22.0/ 95.3±13.1 mmHg, and the mean daytime ambulatory BP was 136.4±15.0/ 86.2±10.7 mmHg. The NT, MHT, WCHT, and SHT groups consisted of 51 (5.3%), 55 (5.7%), 273 (28.2%), and 588 (60.8%) subjects, respectively. The left ventricular mass index was significantly higher in SHT than in the other groups, and was positively correlated with BP, especially ABPM. Compared with NT, the factors associated with MHT were younger age, male gender, higher BMI, clinic BP ≥130 mmHg, and alcohol consumption. Compared with SHT, the factors associated with WCHT were female gender, lower BMI, and clinic BP < 150 mmHg. Conclusions WCHT and MHT were prevalent in the hypertensive population. ABPM was more predictive of target organ damage than clinic BP, and could be useful in identifying subjects at risk for WCHT and MHT. PMID:18309684

    Portopulmonary hypertension (PPH) is clinically defined as the development of pulmonary arterial hypertension complicated by portal hypertension, with or without advanced hepatic disease. Physical signs may be absent in mild to moderate PPH and only appear in a hyperdynamic circulatory state. Similar signs of advanced liver disease can be observed in severe PPH, with ascites and lower extremity edema. Pulmonary hypertension is usually diagnosed after anesthetic induction during liver transplantation (LT). We present intraoperative pulmonary hypertension in a 41-year-old male patient with hepatic cirrhosis. Since this patient had no preoperation laboratory data supporting the diagnosises of pulmonary hypertension and was asymptomatic for a number of years, it was necessary to send him to the intensive care unit after operation. Further study should be focued on the diagnosis and treatment of pulmonary arterial hypertension in order to reduce its mortality. PMID:19084945

    García Donaire, José A; Ruilope, Luis M

    2007-01-01

    Cardiovascular diseases are directly affected by arterial hypertension. When associated with diabetes mellitus, the potential deleterious effects are well amplified. Both conditions play a central role in the pathogenesis of coronary artery disease, heart failure, stroke, and renal insufficiency. Prevalence of hypertension is much higher among diabetic than non-diabetic patients, and the hypertensive patient is more likely to develop type 2 diabetes. Current international guidelines recommend aggressive reductions in blood pressure (BP) in hypertensive patients with additional risk factors, including cardiovascular risk factors, and emphasize the relevance of intensive reduction in patients with diabetes mellitus; a goal of 130/80 mm Hg is required. To achieve BP target a combination of antihypertensives will be needed, and the use of long-acting drugs that are able to provide 24-hour efficacy with a once-daily dosing confers the noteworthy advantages of compliance improvement and BP variation lessening. Lower dosages of the individual treatments of the combination therapy can be administered for the same antihypertensive efficiency as that attained with high dosages of monotherapy. Angiotensin-converting enzyme inhibitors and calcium-channel blockers as a combination have theoretically compelling advantages for vessel homeostasis. Trandolapril/verapamil sustained release combination has showed beneficial effects on cardiac and renal systems as well as its antihypertensive efficacy, with no metabolic disturbances. This combination can be considered as an effective therapy for the diabetic hypertensive population. PMID:17583177

    2015-02-01

    Evidence for the benefits of regular exercise is irrefutable and increasing physical activity levels should be a major goal at all levels of health care. People with hypertension are less physically active than those without hypertension and there is strong evidence supporting the blood pressure-lowering ability of regular exercise, especially in hypertensive individuals. This narrative review discusses evidence relating to exercise and cardiovascular (CV) risk in people with hypertension. Comparisons between aerobic, dynamic resistance, and static resistance exercise have been made along with the merit of different exercise volumes. High-intensity interval training and isometric resistance training appear to have strong CV protective effects, but with limited data in hypertensive people, more work is needed in this area. Screening recommendations, exercise prescriptions, and special considerations are provided as a guide to decrease CV risk among hypertensive people who exercise or wish to begin. It is recommended that hypertensive individuals should aim to perform moderate intensity aerobic exercise activity for at least 30 minutes on most (preferably all) days of the week in addition to resistance exercises on 2-3 days/week. Professionals with expertise in exercise prescription may provide additional benefit to patients with high CV risk or in whom more intense exercise training is planned. Despite lay and media perceptions, CV events associated with exercise are rare and the benefits of regular exercise far outweigh the risks. In summary, current evidence supports the assertion of exercise being a cornerstone therapy in reducing CV risk and in the prevention, treatment, and control of hypertension.

    Prevalence of pulmonary arterial hypertension (PAH) was studied by echocardiography and Doppler in 43 splenectomized patients with various disorders 1-20 years after splenectomy. Pulmonary arterial hypertension was detected only in thalassemia major, intermedia, hereditary sphereocytosis and myelofibrosis groups comprising a total of 21 patients. Six patients out of 21 was found to have PAH with mean pulmonary arterial pressure of 46.28 ± 28.17 mm of Hg. Twenty-one controls having similar duration and type of disease also were assessed for PAH in this case control study 3/21 had pulmonary arterial hypertension in this control group. The difference in number of patients showing pulmonary hypertension between case and control was not statistically significant (Chi square test P=0.29) though the difference in pulmonary arterial pressure between case and control were significantly different (t test P<0.0029) with control group showing a mean pulmonary arterial pressure of 25 ± 19 mm Hg.Platelet count in the splenectomized group was significantly higher (P=0.0029) than the controls. Pulmonary thromboembolism was equally high in the PAH patients with and without splenectomy. Patients undergoing splenectomy due to trauma, immune thrombocytopenia, sideroblastic anemia, extrahepatic portal hypertension, autoimmune hemolytic anemia did not show PAH after splenectomy even years after the procedure PAH following splenectomy is common after certain disorders and control patients in these diseases have tendency to develop PAH even without splenectomy. Pulmonary thromboembolism may be an important pathophysiological mechanism leading to this condition. Patients having hemolytic anemia and myelofibrosis should have regular evaluation of pulmonary arterial pressure whether he/she has been splenectomized or not.This is particularly important as availability of phosphodiesterase inhibitors such as sildenafil allows one to manage these cases.

    OBJECTIVES: Post-transplantation hypertension is prevalent and is associated with increased cardiovascular morbidity and subsequent graft dysfunction. The present study aimed to identify the factors associated with arterial stiffness as measured by the ambulatory arterial stiffness index. METHODS: The current study used a prospective, observational, analytical design to evaluate a group of adult heart transplantation patients. Arterial stiffness was obtained by monitoring ambulatory blood pressure and using the ambulatory arterial stiffness index as the surrogate outcome. Multivariate logistic regression analyses were performed to control confounding. RESULTS: In a group of 85 adult heart transplantation patients, hypertension was independently associated with arterial stiffness (OR 4.98, CI 95% 1.06-23.4) as well as systolic and diastolic blood pressure averages and nighttime descent. CONCLUSIONS: Measurement of ambulatory arterial stiffness index is a new, non-invasive method that is easy to perform, may contribute to better defining arterial stiffness prognosis and is associated with hypertension.

    Summary Background The prevalence of hypertension is growing at an alarming rate. Increasing attention is being focussed on the oxidative stress accompanying this disease. In this study we examined the impact of this disease on some parameters of erythrocytes and human blood plasma. Material/Methods We examined the impact of hypertension on some parameters of erythrocytes and human plasma. The study involved 13 patients with hypertension and 19 healthy subjects. We determined lipid peroxidation, SH groups concentration, antioxidants enzymes activity, ATPase activity, total antioxidant capacity, total cholesterol level and erythrocyte membrane fluidity. Results We found an increased level of lipid peroxidation and the concentration of SH groups in membrane proteins in patients with hypertension, and a decrease in the activity of catalase and superoxide dysmutase. No changes were observed in glutathione peroxidase and ATPase activity, level of total antioxidant capacity, total cholesterol level and fluidity of erythrocyte membranes. Conclusions These results suggest the existence of an impaired oxidative balance in hypertensive human erythrocytes. PMID:22847194

    A prospective trial of a cohort of patients (N = 94) with portal hypertension and history of bleeding was selected for surgery based on strict clinical and laboratory criteria. All of them were treated with portal blood flow preserving procedures. The following selection criteria were used: good cardiopulmonary function without pulmonary hypertension and good liver function (Child-Pugh A). All patients were operated in an elective fashion and the operations performed were: selective shunts (N = 38) (distal splenorenal and splenocaval), low diameter mesocaval shunts (N = 13) and the esophagogastric devascularization with esophageal transection (Sugiura-Futagawa) (N = 43). Patients were selected for each operation according to their anatomical conditions. Sixty-one of the patients were cirrhotics. Operative mortality was 8% and rebleeding was observed in 5% of the cases. Postoperative encephalopathy was seen in seven patients (three selective shunts, two low diameter mesocaval shunts and two devascularizations). In 13 of 62 patients postoperatively evaluated by means of angiography, portal vein thrombosis was shown (seven selective shunts, two low diameter shunts and four devascularizations). Twenty-two patients with preoperative portal vein thrombosis (and treated with a Sugiura-Futagawa operation) were excluded from postoperative angiographic evaluation. Survival (Kaplan-Meier) was 85% at 60 months. Portal blood flow preserving procedures are the treatment of choice for patients with hemorrhagic portal hypertension and good liver function. The kind of operation is selected according to the individual anatomical status of the patient.

    Some studies based on ambulatory blood pressure (BP) monitoring (ABPM) have reported a reduction in sleep-time relative BP decline towards a more non-dipping pattern in the elderly, but rarely have past studies included a proper comparison with younger subjects, and no previous report has evaluated the potential role of hypertension treatment time on nighttime BP regulation in the elderly. Accordingly, we evaluated the influence of age and time-of-day of hypertension treatment on the circadian BP pattern assessed by 48-h ABPM. This cross-sectional study involved 6147 hypertensive patients (3108 men/3039 women), 54.0 ± 13.7 (mean ± SD) yrs of age, with 2137 (978 men/1159 women) being ≥60 yrs of age. At the time of study, 1809 patients were newly diagnosed and untreated, and 4338 were treated with hypertension medications. Among the later, 2641 ingested all their prescribed BP-lowering medications upon awakening, whereas 1697 ingested the full daily dose of ≥1 hypertension medications at bedtime. Diagnosis of hypertension in untreated patients was based on ABPM criteria, specifically an awake systolic (SBP)/diastolic (DBP) BP mean ≥135/85 mm Hg and/or an asleep SBP/DBP mean ≥120/70 mm Hg. Collectively, older in comparison with younger patients were more likely to have diagnoses of microalbuminuria, chronic kidney disease, obstructive sleep apnea, metabolic syndrome, anemia, and/or obesity. In addition, the group of older vs. younger patients had higher glucose, creatinine, uric acid, triglycerides, and fibrinogen, but lower cholesterol, hemoglobin, and estimated glomerular filtration rate. In older compared with younger patients, ambulatory SBP was significantly higher and DBP significantly lower (p < .001), mainly during the hours of nighttime sleep and initial hours after morning awakening. The prevalence of non-dipping was significantly higher in older than younger patients (63.1% vs. 41.1%; p < .001). The largest difference between

    The aims of the study were to investigate, on a daily basis: (i) the development and progress of pressure ulcers, (ii) the documented nursing interventions for prevention and treatment of pressure ulcers, and (iii) when nursing interventions regarding prevention and treatment of pressure ulcers were documented, in relation to patient risk status and the development of pressure ulcers. The study design was prospective, comparative and descriptive. A total of 55 patients with hip fracture were included. To facilitate the nurse's assessment, a 'pressure ulcer card' was developed, consisting of the Modified Norton Scale (MNS) and descriptions of the four stages of pressure ulcers. The incidence of pressure ulcers was 55%. The mean rank of the lowest MNS score was significantly lower for patients who developed pressure ulcers than for patients without pressure ulcers. The majority of the pressure ulcers occurred between admission to the ward and the fourth day after surgery. Documented interventions regarding prevention and treatment were: repositioning, overlays, cushions, use of lotion and observation. The mean number of interventions per patient was 2.2 for patients who developed pressure ulcers during their hospital stay. The comprehensiveness and quality of the nursing record was unsatisfactory, and only three nursing records reached the level required by Swedish law. Preventive interventions such as repositioning were documented when the pressure ulcer had already occurred. The lack of nursing documentation regarding prevention and treatment of pressure ulcers may indicate that nurses did not identify pressure ulcers as a prioritized nursing problem for this patient group. The Modified Norton Scale could be a valuable tool for nurses, both identifying the patient at risk and acting as a guide for nursing interventions. The study was approved by the ethics committee of the Faculty of Medicine at Uppsala University.

    ). The largest difference between groups was in the prevalence of the riser BP pattern, i.e., asleep SBP mean > awake SBP mean (17.6% vs. 7.1% in patients with and without CKD, respectively; p < .001). The riser BP pattern significantly and progressively increased from 8.1% among those with stage 1 CKD to a very high 34.9% of those with stage 5 CKD. Elevated asleep SBP mean was the major basis for the diagnosis of hypertension and/or inadequate BP control among patients with CKD; thus, among the uncontrolled hypertensive patients with CKD, 90.7% had nocturnal hypertension. Our findings document significantly elevated prevalence of a blunted nocturnal BP decline in hypertensive patients with CKD. Most important, prevalence of the riser BP pattern, associated with highest CVD risk among all possible BP patterns, was 2.5-fold more prevalent in CKD, and up to 5-fold more prevalent in end-stage renal disease. Patients with CKD also presented significantly elevated ambulatory PP, reflecting increased arterial stiffness and enhanced CVD risk. Collectively, these findings indicate that CKD should be included among the clinical conditions for which ABPM is mandatory for proper diagnosis and CVD risk assessment, as well as a means to establish the best therapeutic scheme to increase CVD event-free survival.

    The specific features of circadian blood pressure (BP) variations were studied in 162 patients aged 20 to 60 years who had hypertensive disease (HD) in the warm period of a year in different types of weather. In accordance with the type of weather in which daily BP monitoring (DBPM) was performed, the examinees were divided into 2 groups: 1) those examined in droughty (anticyclonic) weather; 2) those examined in moist (cyclonic) weather, The groups were matched by the number (81) of patients, age, gender, duration of the disease, and office BP values. The mean BP during a day, daylight and night hours, the maximum and minimum BP during wake and sleep was significantly high in moist weather. Examining the magnitude of a nocturnal BP decrease indicated that in Group 1, its adequate decrease (the dipper daily curve) was recorded in 72.3% of the patients; inadequate BP decrease (the non-dipper daily curve) was in 24.2%; paradoxical nocturnal hypertension (night peaker) was seen in 1.8%. In Group 2, adequate and inadequate nocturnal BP decreases were observed in 44.4 and 41.3%, respectively; paradoxical nocturnal hypertension was in 7.7%. Statistical processing confirmed the validity of the findings. Moist (cyclonic) weather was ascertained to be marked by the changes in adequate circadian BP variations: a significant mean daily, maximum, and minimum systolic BP (SBP) and diastolic BP (DBP), as well as by the inadequate nocturnal lowering of SBP and DBP, which determines a poor prognosis and may serve as a basis for preventing HD complications in this period of a year.

    Background An assessment of an individual’s hypertension self-care behavior may provide clinicians and practitioners with important information regarding how to better control hypertension. Objectives The objective of this study was to investigate the self-care behaviors of hypertensive patients. Patients and Methods This cross-sectional study was conducted in 2014 in a sample of 1836 patients of both genders who had been diagnosed with hypertension in urban and rural health centers in the Kohgiluyeh Boyerahmad Province in southern Iran. They were randomly selected and were invited to participate in the study. Self-care activities were measured using the H-hypertension self-care activity level effects. Results The mean age of the respondents was 63 (range: 30 - 92), and 36.1% reported adherence to the recommended levels of medication; 24.5% followed the physical activity level guidelines. Less than half (39.2%) met the criteria for practices related to weight management, and adherence to low-salt diet recommendations was also low (12.3%). Overall, 86.7% were nonsmokers, and 100% abstained from alcohol. The results of a logistic regression indicated that gender was significantly associated with adherence to physical activity (OR = 0.716) and non-smoking (OR = 1.503) recommendations; that is, women were more likely to take part in physical activity than men. There was also a significant association between age and adherence to both a low-salt diet (OR = 1.497) and medication (OR = 1.435). Conclusions Based on our findings, it is crucial to implement well-designed educational programs to improve hypertension self-care behaviors. PMID:27621938

    Patients with chronic thromboembolic pulmonary hypertension (CTEPH) experience debilitating symptoms that have a negative impact on their quality of life (QoL) in terms of physical capability, psychological wellbeing and social relationships. The use of QoL measurement tools is important in the assessment of treatment efficacy and in guiding treatment decisions. However, despite the importance of QoL, particularly to the patient, it remains under-reported in clinical studies of CTEPH therapy. CTEPH is unique in pulmonary hypertension in that it is potentially curable by surgery; however, a proportion of patients either have residual PH following surgery or are not operable. Although some patients with CTEPH have been treated off-label with pulmonary arterial hypertension-specific therapies, there have been few randomised controlled trials of these therapies in patients with CTEPH. Moreover, in these trials QoL outcomes are variably assessed, and there is little consistency in the tools used. Here we review the assessment of QoL in patients with CTEPH and the tools that have been used. We also discuss the effect of surgical intervention and medical therapies on QoL. We conclude that further studies of QoL in patients with CTEPH are needed to further validate the optimal QoL tools. PMID:27076580

    Objective To evaluate the efficacy and tolerability of adjunct extended release quetiapine fumarate (quetiapine XR) in patients with generalized anxiety disorder (GAD) and inadequate response to selective serotonin reuptake inhibitors/ serotonin norepinephrine reuptake inhibitors (SSRI/SNRIs). Methods 11-week (1-week single-blind placebo run-in; 8-week randomized treatment; 2-week post-treatment period), double-blind, placebo-controlled study. Patients were randomized to quetiapine XR or placebo adjunct to SSRI/SNRI. 50 mg initial dose; 150 mg/day, Day 3; 300 mg/day, Weeks × and 4 if indicated (Clinical Global Impressions-Severity of Illness [CGI-S] ≥ 4; 150 mg/day tolerated). Primary endpoint: change from randomization to Week 8 in HAM-A total score. Secondary variables: Hamilton Rating Scale for Anxiety (HAM-A) psychic/somatic clusters, response and remission; and CGI-S. Results 409 patients were randomized to quetiapine XR (n = 209) or placebo (n = 200); 41% and 55% of patients, respectively, had dose increases (300 mg/day). Week 8 mean change in HAM-A total score was not statistically significant for quetiapine XR (–10.74; p = 0.079) versus placebo (–9.61). Secondary variables were generally consistent with the primary analysis, except a significant reduction in HAM-A total score at Week 1 (–6.45, quetiapine XR versus –4.47, placebo; p < 0.001); significant improvements in HAM-A psychic cluster (p < 0.05) and CGI-S total (p < 0.05) scores at Week 8. Adverse events (.10% either group) were dry mouth, somnolence, sedation, headache, and dizziness. Conclusions In patients with GAD and inadequate response to SSRI/SNRI, adjunct quetiapine XR did not show a statistically significant effect for the primary endpoint at Week 8, although some secondary endpoints were statistically significant versus placebo. Quetiapine XR was generally well tolerated. PMID:27738353

    Objectives To assess the efficacy and tolerability of lesinurad, an oral selective uric acid reabsorption inhibitor, in combination with allopurinol versus allopurinol alone in patients with gout and an inadequate response to allopurinol. Methods Patients (N=227) with an inadequate response to allopurinol, defined as serum urate (sUA) ≥6 mg/dL on ≥2 occasions ≥2 weeks apart despite ≥6 weeks of allopurinol, were randomised 2:1 to 4 weeks of double-blind treatment with lesinurad (200, 400 or 600 mg/day) or matching placebo in combination with their prestudy allopurinol dose (200–600 mg/day). Colchicine prophylaxis for gout flares was required. The primary end point was percent reduction from baseline sUA levels at 4 weeks. A pharmacokinetic substudy was also conducted. Safety was assessed throughout. Results Patients (n=208) received ≥1 dose of blinded medication. Lesinurad 200, 400 and 600 mg in combination with allopurinol produced significant mean percent reductions from baseline sUA of 16%, 22% and 30%, respectively, versus a mean 3% increase with placebo (p<0.0001, all doses vs placebo). Similar results were observed in patients with mild or moderate renal insufficiency (estimated creatinine clearance 30 to <90 mL/min). The incidence of ≥1 treatment-emergent adverse event was 46%, 48% and 54% with lesinurad 200, 400 and 600 mg, respectively, and 46% with placebo (most frequent, gout flares, arthralgia, headache and nasopharyngitis), with no deaths or serious adverse events. Conclusions Lesinurad achieves clinically relevant and statistically significant reductions in sUA in combination with allopurinol in patients who warrant additional therapy on allopurinol alone.

    High blood pressure in dialysis patients is related to extracellular volume excess and the related increase of systemic vascular resistances. Scribner has early described the treatment of hypertension with ultrafiltration and low salt diet, without any drugs. The dry weight method relies on the progressive reduction of the postdialysis body weight until blood pressure is normalized. Additional measures are needed such as low salt diet, neutral sodium balance during dialysis treatment, stop of antihypertensive drugs, adequate length of the dialysis session, and patient education. It may exist a lag time between the normalization of the extracellular volume and blood pressure. It is related to the correction of the hemodynamic consequences of the extracellular volume overload. Moreover, the dry weight may potentially vary in patients undergoing catabolic intercurrent events. The complications of these changes (severe hypertension, pulmonary oedema) must be anticipated by the nephrologist and the staff to avoid additional morbidity to the patient.

    BACKGROUND Among elderly patients, the management of type 2 diabetes mellitus (T2DM) is complicated by population heterogeneity and elderly-specific complexities. Few studies have been done to understand treatment intensification among elderly patients failing multiple oral antidiabetic drugs (OADs). OBJECTIVE To examine the association between time to treatment intensification of T2DM and elderly-specific patient complexities. METHODS In this observational, retrospective cohort study, elderly (aged ≥ 65 years) Medicare beneficiaries (n = 16,653) with inadequately controlled T2DM (hemoglobin A1c ≥ 8.0% despite 2 OADs) were included. Based on the consensus statement for diabetes care in elderly patients published by the American Diabetes Association and the American Geriatric Society, elderly-specific patient complexities were defined as the presence or absence of 5 geriatric syndromes: cognitive impairment; depression; falls and fall risk; polypharmacy; and urinary incontinence. RESULTS Overall, 48.7% of patients received intensified treatment during follow-up, with median time to intensification 18.5 months (95% CI = 17.7–19.3). Median time to treatment intensification was shorter for elderly patients with T2DM with polypharmacy (16.5 months) and falls and fall risk (12.7 months) versus those without polypharmacy (20.4 months) and no fall risk (18.6 months). Elderly patients with urinary incontinence had a longer median time to treatment intensification (18.6 months) versus those without urinary incontinence (14.6 months). The median time to treatment intensification did not significantly differ by the elderly-specific patient complexities that included cognitive impairment and depression. However, after adjusting for demographic, insurance, clinical characteristics, and health care utilization, we found that only polypharmacy was associated with time to treatment intensification (adjusted hazard ratio, 1.10; 95% CI = 1.04–1.15; P = 0.001).

    Overall forty-eight patients with stage I-II hypertensive disease (HD) were examined. A psychological investigation in the patients was conducted as recommended by Eysenck [correction of Isenk], S. Rosenzweig, Luchier. HD patients presenting with aggravated heredity (AH) and their HD parents are more often than not inclined to introversion. In AH-free HD patients, a high level of neuroticism was recordable as was decrement in their ability to compensate anxiety and a low level of social adaptation. It is suggested that AH HD patients might have some mechanism of compensation of anxiety early in the course of the illness.

    Hypertension induced by obstructive sleep apnea (OSA) may be multifactorial in origin, and systemic inflammation is one of the major factors. However, OSA patients do not always have the identical probability with hypertension even in patients with the same history and degree of OSA. The aim of this study was to compare the levels of inflammation and insulin resistance in two groups of patients who had the same degree as well as the same long history of OSA, but with/without hypertension. OSA patients (Apnea Hyponea Index, AHI ≥ 40/h, n = 70) were examined by polysomnography and blood analysis for the measurements of fasting plasma glucose, serum insulin (FINS), high-sensitivity C-reactive protein (CRP), peptide C,TNF-α, IL-6, and IL-10. Patients with hypertension (n = 40) had higher level of LDL-C and lower HDL-C levels than patients without hypertension. Almost half (16/40) of OSA patients with hypertension had family history of hypertension. Moreover in OSA patients with hypertension, the levels of TNF-α, IL-6, and CRP were higher, but IL-10 was lower than those without hypertension. FINS, peptide C, HOMA-IR, and HOMA-islet were also higher in OSA patients with hypertension. OSA patients with hypertension have higher level of inflammation and insulin resistance. Systemic inflammation and insulin resistance are both important factors for the development of hypertension in OSA patients.

    Background Hypertension, with a global prevalence of 40%, is a risk factor for cardiovascular diseases (CVD). We conducted an exploratory study in Zhejiang China to understand the prevention of CVD among hypertensive patients with a 10 year CVD risk of 20% or higher. We assessed current practices in a rural ‘township hospital’ (a primary care facility), and compared them with international evidence-based practice. Methods A questionnaire survey was conducted to examine the use of modern drugs (antihypertensive drugs, statins and aspirin) and traditional drugs, compliance to medications and lifestyle among 274 hypertensive patients aged 40-74, with a CVD risk of 20% or higher (using the Asian Equation). Results The majority (72%) were diagnosed with hypertension at township hospitals. Only 15% of study participants used two anti-hypertensive drugs, 0.7% took statin and 2.9% aspirin. Only 2.9% combined two types of modern drugs, while 0.4% combined three types (antihypertensives, statins and aspirin). Herbal compounds, sometimes with internationally rarely recommended drugs such as Reserpine were taken by 44%. Analysis of drug adherence showed that 9.8% had discontinued their drug therapy by themselves. 16% had missed doses and these were on less anti-hypertensive drugs than those who did not (t=-5.217, P=0.003). Of all participants, 28% currently smoked, 39% drank regularly and only 21% exercised frequently. The average salt intake per day was 7.1 (±3.8) g, while the national recommended level is 6g. Conclusion The study revealed outdated and inadequate treatment and health education for hypertensive patients, especially for those who have high risk scores for CVD. There is a need to review the community-based guidelines for hypertension management. Health providers and patients should make a transition from solely treating hypertension, towards prevention of CVD. Health system issues need addressing including improving rural health insurance cover and primary

    Pulmonary hypertension (PH) is a common complication of chronic pulmonary diseases, especially in advanced disease, and is associated with greater mortality and worse clinical course. Patients with symptoms that exceed those expected by their pulmonary disease should be further evaluated by echocardiography. Confirmatory right heart catheterization is indicated in those conditions where the results of the hemodynamic assessment will determine treatment options. The treatment of choice for patients who are hypoxemic and have pulmonary hypertension associated with chronic lung disease is long-term oxygen therapy. Conventional vasodilators or drugs approved for pulmonary arterial hypertension are not recommended in patients with mild-to-moderate PH because they may impair gas exchange and because there is a lack of evidence supporting their efficacy. Patients with severe PH should be considered for referral to a center with expertise in PH and lung diseases. Ideally, these patients should be included in randomized controlled trials to determine which patients are more likely to derive benefit and which therapies are most likely to be successful.

    Background The aim of this study was to investigate the efficacy and safety of vildagliptin as an add-on therapy for patients with type 2 diabetes mellitus inadequately controlled with basal insulin. Methods Twenty-four patients treated with basal insulin and oral anti-diabetes drugs were randomly allocated into two groups: the control group (did not receive any add-on drugs) and vildagliptin group (received vildagliptin 100 mg/day for 6 months). The primary outcome was changes in hemoglobin A1c (HbA1c) from baseline to end of study. Results Treatment with vildagliptin significantly reduced HbA1c from 8.1±0.7% at baseline to 7.1±0.7% (P < 0.01), while there was no significant change of HbA1c in the control group. Vildagliptin group showed significant reduction of HbA1c compared with control group (-1.0±0.3% vs. 0.2±0.8%, P < 0.01). In addition, vildagliptin group showed a significant increase in 1,5-anhydroglucitol compared with the control group (4.5 ± 3.4 vs. 0.5 ± 4.1 μg/mL, P < 0.05). Mild hypoglycemia was reported in one patient of the vildagliptin group and two patients of the control group. Conclusion Vildagliptin improved glycemic control without increasing hypoglycemia in Japanese type 2 diabetes inadequately controlled with basal insulin treatment and other oral anti-diabetes drugs.

    Disturbances in macro- and microelements composition may play a significant role in the development of essential hypertension. The aim of the study was to estimate main and trace elements concentration in plasma of hypertensive patients. The study involved 150 subjects, aged 33-60 years, who were allotted into 2 groups: I--50 clinically healthy subjects (controls), II--100 patients with arterial hypertension. Age and sex ratio were similar in the examined groups. Those subjected to the study were not administered any drugs at least 3 months prior to the determination of macro- and microelements. Determinations of trace elements Ca, F, Na, K, Mg, Fe, Zn, Cu, Ni, Mo, Al, Cd, Fb, Mu, Se, Cr, Co, Li, V, B, Ba, were performed with atomic emission spectrometer with plasmic excitation (ICP MS Philips PU). In group II in comparison to group I (controls) higher values of Fe, Pb, Al, Cd, Co, B i Ba were observed, as well as higher Zn/Cu ratio; but lower values of Cu and lower Ca/Pb, Ca/Al, Zn/Fe, Se/Fe, Zn/Al, Zn/Cd, Se/Pb, Se/Al, Se/Cd ratio. Increase of prooxidative and decrease,of antioxidative elements in plasma may significantly contribute to the essential hypertension pathogenesis probably through oxidative stress development.

    The aim of the present review is to consider the clinical relevance of individualized blood pressure (BP) goal under treatment in hypertensive patients according to their age, comorbidities or established cardiovascular (CV) disease. Evidence from large-scale randomized trials to support a lower BP goal, as initially recommended by guidelines in high-risk hypertensive patients, were lacking. Recently, the randomized intervention SPRINT trial studied two treatment targets for systolic BP (120mm Hg versus 140mm Hg in the intensive and standard treatment group, respectively) among high-risk hypertensive patients, without diabetes and without a history of prior stroke. The trial was stopped prematurely owing to a significantly lower rate of the primary composite outcome and all-cause mortality in the intensive treatment group. Several practical questions have to be considered. First, using an automated measurement system at an office visit during the SPRINT protocol, while the patient was seated alone after 5min of quiet rest, may likely have resulted in lower BP values than would normally be obtained with the routine BP measurement. A target systolic of 120mm Hg in SRPINT trial may be thus equated to a target systolic BP of 130mm Hg in the real-world office setting. Second, careful and repeated examinations of SPRINT participants may have led to fewer adverse events (more frequent in the intensive treatment group) than that expected in the real-world setting. The safety profile of this intensive treatment approach should therefore remain a matter of concern in clinical practice, especially in elderly patients, in diabetic patients or with established CV or renal disease. Orthostatic hypotension should alert the clinician to withhold up titration. Third, beyond the question of BP goal, choice of antihypertensive medication and effective 24-h BP control are important to consider in the context of BP-lowering strategy. In particular, ambulatory BP measurements and during

    Hypertension is present in 30% of the adult US population and is a major contributor to cardiovascular disease. The established office-based approach yields only 50% blood pressure control rates and low levels of patient engagement. Available home technology now provides accurate, reliable data that can be transmitted directly to the electronic medical record. We evaluated blood pressure control in 156 patients with uncontrolled hypertension enrolled into a home-based digital-medicine blood pressure program and compared them with 400 patients (matched to age, sex, body mass index, and blood pressure) in a usual-care group after 90 days. Digital-medicine patients completed questionnaires online, were asked to submit at least one blood pressure reading/week, and received medication management and lifestyle recommendations via a clinical pharmacist and a health coach. Blood pressure units were commercially available that transmitted data directly to the electronic medical record. Digital-medicine patients averaged 4.2 blood pressure readings per week. At 90 days, 71% of digital-medicine vs 31% of usual-care patients had achieved target blood pressure control. Mean decrease in systolic/diastolic blood pressure was 14/5 mm Hg in digital medicine, vs 4/2 mm Hg in usual care (P < .001). Excess sodium consumption decreased from 32% to 8% in the digital-medicine group (P = .004). Mean patient activation increased from 41.9 to 44.1 (P = .008), and the percentage of patients with low patient activation decreased from 15% to 6% (P = .03) in the digital-medicine group. A digital hypertension program is feasible and associated with significant improvement in blood pressure control rates and lifestyle change. Utilization of a virtual health intervention using connected devices improves patient activation and is well accepted by patients.

    Purpose A step-up strategy for diet therapy and/or single oral antihyperglycemic agent (OHA) regimens has not yet been established. The aim of this study was to evaluate hemoglobin A1c (HbA1c) as a primary end point, and the pleiotropic effects on metabolic and cardiovascular parameters as secondary end points, of sitagliptin versus voglibose in patients with type 2 diabetes with inadequate glycemic control while on diet therapy and/or treatment with a single OHA. Methods In this multicenter, randomized, open-label, parallel-group trial, a total of 260 patients with inadequately controlled type 2 diabetes (HbA1c levels >6.9%) were randomly assigned to receive either sitagliptin (50 mg, once daily) or voglibose (0.6 mg, thrice daily) for 12 weeks. The primary end point was HbA1c levels. Results Patients receiving sitagliptin showed a significantly greater decrease in HbA1c levels (−0.78±0.69%) compared with those receiving voglibose (−0.30±0.78%). Sitagliptin treatment also lowered serum alkaline phosphatase levels and increased serum creatinine, uric acid, cystatin-C and homeostasis model assessment-β values. Voglibose increased low-density lipoprotein-cholesterol levels and altered serum levels of several fatty acids, and increased Δ-5 desaturase activity. Both drugs increased serum adiponectin. The incidence of adverse events (AEs) was significantly lower in the sitagliptin group, due to the decreased incidence of gastrointestinal AEs. Conclusions Sitagliptin shows superior antihyperglycemic effects compared with voglibose as a first-line or second-line therapy. However, both agents possess unique pleiotropic effects that lead to reduced cardiovascular risk in Japanese people with type 2 diabetes. Trial registration number UMIN 000003503. PMID:27110370

    STUDY OBJECTIVE: To assess the incidence of pulmonary hypertension (PH) in patients with chronic myeloproliferative disorders (CMPD). METHOD: Twenty-seven patients with a diagnosis of CMPD were included in the study. Patients were excluded if they had a secondary cause of PH. Diagnosis of PH was established if right ventricular systolic pressure (RVSP) by transthoracic echocardiography (TTE) was >35 mmHg. RESULTS: Diagnosis of PH was established in 14 out of 27 patients. Two patients were excluded from analysis because of poor ejection fraction on TTE, resulting in a final diagnosis of PH in 12 of 25 (48%) patients. Of these 25 patients, seven of nine with essential thrombocytosis (ET), five of 14 with polycythemia vera (PV), and 0 out of two with chronic myeloid leukemia (CML) had PH. All patients were asymptomatic at the time of their most recent visit. There was no relationship between PH and age at diagnosis, duration of disease, platelet count and hematocrit at diagnosis or during follow-up, both for the entire cohort or for specific diagnosis of ET or PV. CONCLUSION: Pulmonary hypertension appears to be common in patients with CMPD. Further studies are needed to evaluate the impact of treatment on PH and long-term survival in these patients.

    An increase in splanchnic blood flow is a physiological response to food intake. In patients with cirrhosis whose hepatic vascular resistance is already high, this increase in flow leads to marked increases in portal pressure. This study investigates whether octreotide prevents the increases in hepatic flow and portal pressure that follow the ingestion of a meal in patients with cirrhosis. Twenty-two patients with cirrhosis and portal hypertension were randomized to receive a mixed liquid meal (520 kcal) plus a single subcutaneous injection of either placebo or octreotide (200 micrograms). In the placebo group the ingestion of a meal was followed by an increase in the hepatic venous pressure gradient (+ 19.4 +/- 4.3%, p < 0.01) and hepatic blood flow (+ 38.2 +/- 14.6%, p < 0.05) at 30 min. In contrast, in the octreotide group eating caused no significant change in the hepatic venous pressure gradient (-2.8 +/- 3.6%, NS), while hepatic flow was decreased (-6.08 +/- 5.4%, p < 0.05). Octreotide blunted the postprandial increase in serum insulin and glucagon levels observed in the placebo group. In conclusion, in patients with cirrhosis and portal hypertension, octreotide prevents the postprandial increase in hepatic blood flow, and consequently also in portal pressure. These findings suggest that this drug could play a role in the long-term management of portal hypertension.

    Objective. To evaluate the differences in treatment compliance with vildagliptin/metformin fixed-dose versus free-dose combination therapy in patients with type 2 diabetes mellitus (T2DM) in Greece. Design. Adult patients with T2DM, inadequately controlled with metformin monotherapy, (850 mg bid), participated in this 24-week, multicenter, observational study. Patients were enrolled in two cohorts: vildagliptin/metformin fixed-dose combination (group A) and vildagliptin metformin free-dose combination (group B). Results. 659 patients were enrolled, 360 were male, with mean BMI 30.1, mean T2DM duration 59.6 months, and mean HbA1c at baseline 8%; 366 patients were assigned to group A and 293 to group B; data for 3 patients was missing. In group A, 98.9% of patients were compliant with their treatment compared to 84.6% of group B. The odds ratio for compliance in group A versus B was (OR) 18.9 (95% CI: 6.2, 57.7; P < 0.001). In group A mean HbA1c decreased from 8.1% at baseline to 6.9% (P < 0.001) at the study end and from 7.9% to 6.8% (P < 0.001) in group B. Conclusions. Patients in group A were more compliant than patients in group B. These results are in accordance with international literature suggesting that fixed-dose combination therapies lead to increased compliance to treatment.

    Pulmonary Hypertension (PH) is definited by a mean pulmonary artery pressure (PAPm) >25 mmHg at rest. The Dana Point 2008 Revised Classification System represents the most recent classification system update with respect of various etiologies of PH. About 10 % of adolescents or adults with uncorrected congenital heart disease (CHD) with left-to-right shunt and high pulmonary blood flow develop Pulmonary Arterial Hypertension (PAH) . Progressive vascular remodeling and increase in pulmonary vascular resistance (PVR) may ultimately lead to reversal of the shunt (pulmonary to systemic) causing cyanosis and determining the so-called Eisenmenger Syndrome (ES). Recent advances in the early diagnosis and medical targeted treatment of adult patients with CHD-PAH and ES can improve PAP, PVR and exercise tolerance, together with NYHA Class and survival, and may potentially reverse the vascular remodeling process in selected patients.

We developed an intelligent dialogue system that interacts with hypertensive patients to collect data about their health status. Patients thus avoid the inconvenience of traveling for frequent face to face visits to monitor the clinical variables they can easily measure at home; the physician is facilitated in acquiring patient information and cardiovascular risk, which is evaluated from the data according to noted guidelines. Controlled trials to assess the clinical efficacy are under way.

    Prevalence of pulmonary arterial hypertension (PAH) was studied by Echocardiography and Doppler in 43 splenectomised patients with various disorders 1-20 years after splenectomy. PAH was detected only in thalassemia major, intermedia, hereditary sphereocytosis and myelofibrosis groups comprising a total of 21 patients. Six patients out of 21 was found to have PAH with mean pulmonary arterial pressure of 46.28 ± 28.17 mmHg. Twenty one controls having similar duration and type of disease also were assessed for PAH in this case control study 3/21 had PAH in this control group. The difference in number of patients showing pulmonary hypertension between case and control was not statistically significant (chi-square test p = 0.29-though the difference in pulmonary arterial pressure between case and control were significantly different (t-test p<0.0029) with control group showing a mean pulmonary arterial pressure of 25 ± 19 mmHg.Platelet count in the splenectomised group was significantly higher (p = 0.0029) than the controls. Pulmonary thromboembolism was equally high in the PAH patients with and without splenectomy. Patients undergoing splenectomy due to trauma, immune thrombocytopenia, sideroblastic anemia, extra hepatic portal hypertension, autoimmune hemolytic anemia did not show PAH after splenectomy even years after the procedure PAH following splenectomy is common after certain disorders and control patients with these diseases have tendency to develop PAH even without splenectomy. Pulmonary thromboembolism may be an important pathophysiological mechanism leading to this condition. Patients having hemolytic anemia and myelofibrosis should have regular evaluation of pulmonary arterial pressure whether he/she has been splenectomised or not. This is particularly important as availability of phosphodiesterase inhibitors like sildenafil allows one to manage these cases.

    The authors examined the relationship between thiazide-type diuretics and fluid spaces in a cohort of hypertensive patients in a retrospective study of 60 stable hypertensive patients without renal abnormalities who underwent whole-body bioimpedance analysis. Overhydration was greater in the diuretic group, but only to a nonsignificant degree (5.9 vs. 2.9%; P=.21). The total body water did not differ in the two groups (41.8 L vs. 40.5 L; P=.64). Extracellular fluid volume (ECV) (19.7 L vs. 18.5 L; P=.35) and intracellular fluid volume (ICV) spaces (20.8 L vs. 21.3 L; P=.75) were also not significantly different in the two groups. The ratio of ICV:ECV, however, appeared different: 1.05 vs 1.15 (P=.017) and the effect was maintained in the linear regression-adjusted model (β coefficient: -0.143; P=.001). The diuretic-related distortion of ICV:ECV ratio indicates potential fluid redistribution in hypertensive patients, with ICV participating in the process.

    Background: The long allele of a functional promoter polymorphism in the serotonin transporter (SERT) is associated with an increased risk of some forms of pulmonary arterial hypertension. We hypothesized that the long allele or other polymorphisms in SERT would be associated with an increased risk of portopulmonary hypertension (PPHTN) in patients with advanced liver disease. Methods: We performed a multicenter case-control study. Subjects undergoing liver transplant evaluation at seven centers were prospectively screened for the presence of PPHTN using transthoracic echocardiography. PPHTN was confirmed by right heart catheterization using standard criteria. Results: The study sample included 30 case patients with PPHTN and 109 control subjects with advanced liver disease. There was no significant association between the long allele and case status in an adjusted additive model (odds ratio, 0.63; 95% confidence interval, 0.33 to 1.21; p = 0.17). If anything, LL genotype tended to be associated with a lower risk of PPHTN. There were no associations between other SERT polymorphisms and PPHTN. Conclusions: SERT polymorphisms are not associated with the risk of PPHTN in patients with advanced liver disease. Other clinical or genetic risk factors may play a role in this complication of portal hypertension. PMID:19141529

    Objective To evaluate the efficacy and safety of ABT‐494, a selective JAK‐1 inhibitor, in patients with moderate‐to‐severe rheumatoid arthritis (RA) and an inadequate response to methotrexate (MTX). Methods Three hundred RA patients receiving stable doses of MTX were randomly assigned equally to receive immediate‐release ABT‐494 at 3, 6, 12, or 18 mg twice daily, 24 mg once daily, or placebo for 12 weeks. The primary efficacy end point was the proportion of patients meeting the American College of Rheumatology 20% improvement criteria (achieving an ACR20 response) at week 12, as determined using the last observation carried forward method. Results At week 12, the proportion of ACR20 responses was higher with ABT‐494 (62%, 68%, 80%, 64%, and 76% for the 3, 6, 12, 18, and 24 mg doses, respectively) than with placebo (46%) (using nonresponder imputation) (P < 0.05 for the 6, 12, and 24 mg doses). There was a significant dose‐response relationship among all ABT‐494 doses (P < 0.001). The proportions of patients achieving ACR50 and ACR70 responses were significantly higher for all ABT‐494 doses (except the 12 mg dose for the ACR70 response) than for placebo, as were changes in the Disease Activity Score in 28 joints using the C‐reactive protein level (DAS28‐CRP). Rapid improvement was demonstrated by significant differences in ACR20 response rates and changes in the DAS28‐CRP for all doses compared with placebo at week 2 (the first postbaseline visit). The incidence of adverse events was similar across groups; most were mild, and infections were the most frequent. One serious infection (community‐acquired pneumonia) occurred with ABT‐494 at 12 mg. There were dose‐dependent increases in high‐density lipoprotein (HDL) and low‐density lipoprotein (LDL) cholesterol, but the LDL cholesterol:HDL cholesterol ratios were unchanged through week 12. Mean hemoglobin levels remained stable at lower doses, but decreases were observed at

    Objective To compare the efficacy and safety of ABT‐494, a novel selective JAK‐1 inhibitor, with placebo in patients with moderate‐to‐severe rheumatoid arthritis (RA) and an inadequate response or intolerance to at least 1 anti–tumor necrosis factor (anti‐TNF) agent. Methods In this 12‐week, double‐blind, placebo‐controlled, dose‐ranging study, 276 RA patients receiving a stable dose of methotrexate (MTX) who had previously received treatment with at least 1 anti‐TNF agent were randomized equally to receive immediate‐release ABT‐494 at 3, 6, 12, or 18 mg twice daily or matching placebo twice daily. The primary end point was the proportion of patients meeting the American College of Rheumatology 20% improvement criteria (achieving an ACR20 response) at week 12. Results At week 12, significantly more patients receiving ABT‐494 (53–71%) than those receiving placebo (34%) achieved an ACR20 response (by nonresponder imputation analysis) (P < 0.05), with a dose‐response relationship among all ABT‐494 doses (P < 0.001). ACR50 and ACR70 response rates were significantly higher in those receiving ABT‐494 (36–42% and 22–26%, respectively) than in those receiving placebo (16% and 4%, respectively). Changes from baseline in the Disease Activity Score in 28 joints using the C‐reactive protein level (DAS28‐CRP) were significantly greater for all doses of ABT‐494 than for placebo (P ≤ 0.01). Onset of action of ABT‐494 was rapid, with significant differences from placebo at week 2 both in ACR20 response rate (for 12 and 18 mg) and in change in the DAS28‐CRP (P < 0.001 for 6–18 mg). The most frequent adverse events (AEs) were headache, nausea, upper respiratory tract infection, and urinary tract infection. Infection rates were higher at higher doses of ABT‐494, but no infections were serious. No deaths were reported among those receiving ABT‐494. Conclusion In patients with an inadequate response or

    Background Pulmonary hypertension (PH) is a common finding in patients with chronic fibrosing idiopathic interstitial pneumonias (IIP). Little is known about the response to pulmonary vasodilator therapy in this patient population. COMPERA is an international registry that prospectively captures data from patients with various forms of PH receiving pulmonary vasodilator therapies. Methods We retrieved data from COMPERA to compare patient characteristics, treatment patterns, response to therapy and survival in newly diagnosed patients with idiopathic pulmonary arterial hypertension (IPAH) and PH associated with IIP (PH-IIP). Results Compared to patients with IPAH (n = 798), patients with PH-IIP (n = 151) were older and predominantly males. Patients with PH-IIP were treated predominantly with phosphodiesterase-5 inhibitors (88% at entry, 87% after 1 year). From baseline to the first follow-up visit, the median improvement in 6MWD was 30 m in patients with IPAH and 24.5 m in patients with PH-IIP (p = 0.457 for the difference between both groups). Improvements in NYHA functional class were observed in 22.4% and 29.5% of these patients, respectively (p = 0.179 for the difference between both groups). Survival rates were significantly worse in PH-IIP than in IPAH (3-year survival 34.0 versus 68.6%; p<0.001). Total lung capacity, NYHA class IV, and mixed-venous oxygen saturation were independent predictors of survival in patients with PH-IIP. Conclusions Patients with PH-IIP have a dismal prognosis. Our results suggest that pulmonary vasodilator therapy may be associated with short-term functional improvement in some of these patients but it is unclear whether this treatment affects survival.

    Ischemic heart disease (IHD) affects about 16 million adults in the USA. Many more individuals likely harbor subclinical coronary disease. Hypertension (HTN) continues to be a potent and widespread risk factor for IHD. Among other Framingham risk factors of tobacco use, diabetes mellitus, dyslipidemia, and left ventricular hypertrophy, HTN plays an independent role in augmenting IHD risk, as well as a multiplicative role with respect to adverse outcomes when HTN is present concurrently with the other major IHD risk factors listed above. Over the past two decades, numerous studies and guideline reports have been presented with the aims of (a) elucidating the pathophysiology of IHD, (b) delineating an ideal blood pressure (BP) threshold at which to institute pharmacotherapy, and (c) defining the optimal pharmacologic elements of a therapeutic regimen. While there are active debates surrounding the existence and relevance of the J curve in IHD patients who have HTN, as well as the numerical level of the BP cutoff justifying drug therapy in the general population, there is a general consensus that the BP target in IHD patients should be lower than 140/90 mmHg. The most appropriate class (or classes) of medication recommended will depend on the comorbid conditions associated with each individual patient. Overall, however, there is no major evidence underscoring a significant difference between drug classes, provided the target BP is achieved, although it should be pointed out that the most recent (2015) American Heart Association (AHA)/American College of Cardiology (ACC)/American Society of Hypertension (ASH) guideline statement now elevates beta-blockers (BB) to the same level of recommendation as other classes of hypertension drugs in the treatment of patients who have hypertension and ischemic heart disease. Although most agents that reduce blood pressure will correspondingly lower myocardial workload, BB may exhibit a special advantage in IHD patients because BB

    Successful blood pressure (BP) control requires good adherence to medication and specific health-related behaviors. However, the BP control rate is not optimal, and limited research has focused on the patient's perspective. This study aimed at investigating the illness perceptions of hypertensive patients and how they relate to drug adherence. One hundred and seventeen hypertensive patients enrolled in this study, and data were collected in a family physician clinic of a medical center located in northern Taiwan. The Illness Perception Questionnaire was administered, and medication adherence and demographic data were also collected. Results showed the patients' perceptions of their hypertension, that it was a chronically severe but stable disease, and the patients were confident in the effectiveness of medical treatments and their ability to control their disease. The participants were divided into three clusters by cluster analysis. There were 46.15% participants in the first cluster; they had less negative belief in their illness consequence and less negative emotional responses, but a low personal sense of control. The second cluster (11.97%) had more negative emotional responses and more negative beliefs in their illness consequence, but these individuals scored highly on their personal sense of control and treatment control beliefs. The third cluster (41.88%) had scores between clusters 1 and 2. Cluster 1 had the best drug adherence, and cluster 2 had the worst drug adherence (χ(2) = 7.67, p < 0.05). It may be beneficial for clinical physicians to pay attention to patients' illness perceptions, including their negative emotional response and symptoms, in order to improve their drug adherence.

    The objective of this study was to investigate the efficacy and safety of adjunctive lanicemine (NMDA channel blocker) in the treatment of major depressive disorder (MDD) over 12 weeks. This phase IIb, randomized, parallel-arm, double-blind, placebo-controlled study was conducted at 49 centers in four countries between December 2011 and August 2013 in 302 patients aged 18–70 years, meeting criteria for single episode or recurrent MDD and with a history of inadequate treatment response. Patients were required to be taking an allowed antidepressant for at least four weeks prior to screening. Patients were randomized equally to receive 15 double-blind intravenous infusions of adjunctive lanicemine 50 mg, lanicemine 100 mg, or saline over a 12-week course, in addition to ongoing antidepressant. The primary efficacy end point was change in Montgomery-Åsberg Depression Rating Scale (MADRS) total score from baseline to week 6. Secondary efficacy outcome variables included change in MADRS score from baseline to week 12, response and remission rates, and changes in Clinical Global Impression scale, Quick Inventory of Depressive Symptomology Self-Report score, and Sheehan Disability Scale score. Of 302 randomized patients, 240 (79.5%) completed treatment. Although lanicemine was generally well tolerated, neither dose was superior to placebo in reducing depressive symptoms on the primary end point or any secondary measures. There was no significant difference between lanicemine and placebo treatment on any outcome measures related to MDD. Post hoc analyses were performed to explore the possible effects of trial design and patient characteristics in accounting for the contrasting results with a previously reported trial. PMID:27681442

Studies conducted worldwide suggest an overall small, yet useful, role of omega-3 PUFAs in reducing blood pressure in hypertensive patients. However there is no substantial data in this regard from population based in Middle East and Asia. Objectives To determine the effects of (omega-3) PUFA supplementation on the blood pressure of hypertensive patient. To identify if male and female hypertensive patients respond differently to PUFA. To identify if response of hypertensive patients to PUFA varies with the duration of hypertension and co-existence of diabetes/dyslipidemia. Materials and methods This observational study was conducted among hypertensive patients visiting OPD of the Gulf Medical College Hospital, Ajman, UAE, during the period Jan–Dec 2012. A total of 100 hypertensive patients on treatment with their antihypertensive medications, 50 of whom were taking n-3 PUFA supplementation, were followed up for a period of 3 months. Comparisons were drawn between the BP recordings at the time of enrollment in the study and their follow up values 3 months after enrollment. Results There was a statistically significant reduction in both the systolic and diastolic blood pressures after 3 months of PUFA therapy. The BP lowering effect of PUFA was more in males. A statistically significant reduction in BP was noted in non-diabetic patients and patients with long standing hypertension. Conclusion Findings of the study suggest that omega-3 PUFA dietary supplements augment the benefits of pharmacotherapy in hypertension. PMID:25173198

    Objectives To study the responsiveness of a combined power Doppler and greyscale ultrasound (PDUS) score for assessing synovitis in biologic-naïve patients with rheumatoid arthritis (RA) starting abatacept plus methotrexate (MTX). Methods In this open-label, multicentre, single-arm study, patients with RA (MTX inadequate responders) received intravenous abatacept (∼10 mg/kg) plus MTX for 24 weeks. A composite PDUS synovitis score, developed by the Outcome Measures in Rheumatology–European League Against Rheumatism (OMERACT–EULAR)-Ultrasound Task Force, was used to evaluate individual joints. The maximal score of each joint was added into a Global OMERACT–EULAR Synovitis Score (GLOESS) for bilateral metacarpophalangeal joints (MCPs) 2–5 (primary objective). The value of GLOESS containing other joint sets was explored, along with clinical efficacy. Results Eighty-nine patients completed the 24-week treatment period. The earliest PDUS sign of improvement in synovitis was at week 1 (mean change in GLOESS (MCPs 2–5): −0.7 (95% CIs −1.2 to −0.1)), with continuous improvement to week 24. Early improvement was observed in the component scores (power Doppler signal at week 1, synovial hyperplasia at week 2, joint effusion at week 4). Comparable changes were observed for 22 paired joints and minimal joint subsets. Mean Disease Activity Score 28 (C reactive protein) was significantly reduced from weeks 1 to 24, reaching clinical meaningful improvement (change ≥1.2) at week 8. Conclusions In this first international prospective study, the composite PDUS score is responsive to abatacept. GLOESS demonstrated the rapid onset of action of abatacept, regardless of the number of joints examined. Ultrasound is an objective tool to monitor patients with RA under treatment.

    OBJECTIVE: To evaluate the role of right heart catheterization in the diagnosis of pulmonary arterial hypertension (PAH). METHODS: We evaluated clinical, functional, and hemodynamic data from all patients who underwent right heart catheterization because of diagnostic suspicion of PAH-in the absence of severe left ventricular dysfunction (LVD), significant changes in pulmonary function tests, and ventilation/perfusion lung scintigraphy findings consistent with chronic pulmonary thromboembolism-between 2008 and 2013 at our facility. RESULTS: During the study period, 384 patients underwent diagnostic cardiac catheterization at our facility. Pulmonary hypertension (PH) was confirmed in 302 patients (78.6%). The mean age of those patients was 48.7 years. The patients without PH showed better hemodynamic profiles and lower levels of B-type natriuretic peptide. Nevertheless, 13.8% of the patients without PH were categorized as New York Heart Association functional class III or IV. Of the 218 patients who met the inclusion criteria, 40 (18.3%) and 178 (81.7%) were diagnosed with PH associated with LVD (PH-LVD) and with PAH, respectively. The patients in the HP-LVD group were significantly older than were those in the PAH group (p < 0.0001). CONCLUSIONS: The proportional difference between the PAH and PH-LVD groups was quite significant, considering the absence of echocardiographic signs suggestive of severe LVD during the pre-catheterization investigation. Our results highlight the fundamental role of cardiac catheterization in the diagnosis of PAH, especially in older patients, in whom the prevalence of LVD that has gone undiagnosed by non-invasive tests is particularly relevant.

    The literature about possible cardiovascular consequences of diagnostic inertia in diabetes is scarce. We examined the influence of undetected high fasting blood glucose (FBG) levels on the cardiovascular risk and poor control of cardiovascular risk factors in hypertensive or obese patients, with no previous diagnosis of diabetes mellitus (i.e., diagnostic inertia). A cross-sectional study during a preventive program in a Spanish region was performed in 2003–2004. The participants were aged ≥40 years and did not have diabetes but were hypertensive (n = 5, 347) or obese (n = 7, 833). The outcomes were high cardiovascular risk (SCORE ≥5%), poor control of the blood pressure (≥140/90 mmHg) and class II obesity. The relationship was examined between FBG and the main parameters, calculating the adjusted odd ratios with multivariate models. Higher values of FBG were associated with all the outcomes. A more proactive attitude towards the diagnosis of diabetes mellitus in the hypertensive and obese population should be adopted. PMID:25922799

    Pulmonary thromboendarterectomy is the treatment of choice in patients with chronic thromboembolic pulmonary hypertension (CTEPH). However, specific medical treatment of pulmonary hypertension (PH) can be an alternative or play a complementary role to surgery. Thus, in patients unsuitable for surgery due to distal thrombotic obstruction, residual or persistent PH after surgery or very severe PH and a high-risk hemodynamic profile, medical treatment may improve their clinical course and the outcome of thromboendarterectomy. Patients with distal obstruction in the pulmonary tree and those with residual PH after surgery show clinical and hemodynamic deterioration due to progression of the pulmonary vascular disease in the smallcaliber arterioles. Conventional treatment with diuretics, anticoagulants and oxygen therapy has been demonstrated to have little effectiveness. In the last decade, numerous drugs have been developed for the treatment of PH: prostacyclin analogs, endothelin receptor antagonists, and phosphodiesterase-5 inhibitors acting principally in vascular remodelling of small-caliber arterioles. Although evidence of the effectiveness of these drugs in PH and the histological similarity of small-vessel vasculopathy in CTEPH to that of other forms of PH provide the main rationale for the use of these drugs in patients with CTEPH, the evidence from clinical trials is still limited.

    Pulmonary arterial hypertension (PAH) is a rare and potentially fatal disease whose management is usually restricted to a few specialised centres. As patients do not necessarily live in the neighbourhood of these centres, daily care and emergencies have to be delegated to first and second lines. Treatment guidelines do not usually provide recommendations for acute emergency situations as evidence is scarce. This short review provides a description of our therapeutic protocols based on available data. A model of transmural organisation of care for PAH patients, currently applied in Belgium, is described. Thereafter, based on an analysis of the reasons of death in the PAH population, a review of the main emergencies is provided. Cardiac arrest and resuscitation, decompensated right heart failure, respiratory failure, arrhythmia, pericardial effusion, haemoptysis, surgery and drug-related adverse events will be discussed successively. Case reports showing the precariousness of PAH patients will enforce our thesis of the need for optimal patient management organisation.

    What is already known about this subject Hypertension is associated with increased arterial stiffness and impaired endothelial function. Arterial vasodilation depends on endothelial function and can be regulated by β2-adrenergic stimulation. Doxazosin is a known and potent antihypertensive agent. However, its effects on arterial stiffness and vasodilation have not been fully established. What this study adds Sixteen-week add-on antihypertensive therapy with 4 mg of doxazosin extended release daily: Reduces arterial stiffness. Improves albuterol-mediated, i.e. endothelium-dependent, arterial vasodilation. Does not influence nitroglycerin-mediated, i.e. endothelium-independent, arterial vasodilation. Aims Doxazosin is an antihypertensive agent with largely unknown effects on arterial stiffness and vasodilation. The aim of this study was to determine the effect of the addition of doxazosin extended-release (ER) to the standard management of hypertension in patients with inadequately controlled blood pressure (BP) on arterial stiffness and arterial vasodilation. Methods Twenty patients with inadequately controlled hypertension were treated with 4 mg doxazosin ER daily for 16 weeks as an adjunct to their existing antihypertensive regimen. Results Doxazosin ER add-on therapy was associated with significantly reduced systolic (P < 0.0001) and diastolic (P = 0.0003) BP, improved arterial stiffness (determined by digital volume pulse analysis (P = 0.048) and albuterol-mediated arterial vasodilation (P = 0.030). Conclusions Add-on therapy with 4 mg of doxazosin ER daily reduces BP and arterial stiffness and improves arterial vasodilation in response to adrenergic stimulation. PMID:17635498

    Introduction: The term masked hypertension (MH) should be used for untreated individuals who have normal office blood pressure but elevated ambulatory blood pressure. For treated patients, this condition should be termed masked uncontrolled hypertension (MUCH). Research Objectives: Masked uncontrolled hypertension (MUCH) has gone unrecognized because few studies have used 24-h ABPM to determine the prevalence of suboptimal BP control in seemingly well-treated patients, and there are few such studies in large cohorts of treated patients attending usual clinical practice. This is important because masked hypertension is associated with a high risk of cardiovascular events. This study was conducted to obtain more information about the association between hypertension and other CV risk factors, about office and ambulatory blood pressure (BP) control as well as on cardiovascular (CV) risk profile in treated hypertensive patients, also to define the prevalence and characteristics of masked uncontrolled hypertension (MUCH) among treated hypertensive patients in routine clinical practice. Patients and methods: In this study 2514 male and female patients were included during a period of 5 years follow up. All patients have ambulatory blood pressure monitoring (ABPM) for at least 24h. We identified patients with treated and controlled BP according to current international guidelines (clinic BP, 140/90mmHg). Cardiovascular risk assessment was based on personal history, clinic BP values, as well as target organ damage evaluation. Masked uncontrolled hypertension (MUCH) was diagnosed in these patients if despite controlled clinic BP, the mean 24-h ABPM average remained elevated (24-h systolic BP ≥130mmHg and/or 24-h diastolic BP ≥80mmHg). Results: Patients had a mean age of 60.2+10 years, and the majority of them (94.6%) were followed by specialist physicians. Average clinic BP was 150.4+16/89.9+12 mmHg. About 70% of patients displayed a very high-risk profile. Ambulatory

    The incidence of dysmetabolic factors in 100 elderly patients with hypertension stage II and the role of melatoninproducing function of epiphysis (pineal gland) in the development of these disorders were studied. It was found that the decrease of melatoninproducing function is one of the factors causing disorders of carbohydrate and lipid metabolism in elderly patients with hypertension. Simultaneous application of Melatonin with lisinopril or amlodipine have the normalizing effect on metabolic parameters affected in patients with arterial hypertension.

    Objective To evaluate feasibility, efficacy and tolerability of Sudarshan Kriya yoga (SKY) as an adjunctive intervention in patients with major depressive disorder (MDD) with inadequate response to antidepressant treatment. Method Patients with MDD (defined by DSM-IV-TR) depressed despite ≥8 weeks of antidepressant treatment were randomized to SKY or a waitlist control (delayed yoga) arm for 8 weeks. The primary efficacy end point was change in 17-item Hamilton Depression Rating Scale (HDRS-17) total score from baseline to 2 months. The key secondary efficacy end points were change in Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI) total scores. Analyses of the intent-to-treat (ITT) and completer sample were performed. The study was conducted at the University of Pennsylvania between October 2014 and December 2015. Results In the ITT sample (n=25), the SKY arm (n=13) showed a greater improvement in HDRS-17 total score compared to waitlist control (n=12)(−9.77 vs. 0.50, P =.0032). SKY also showed greater reduction in BDI total score versus waitlist control (−17.23 vs. −1.75, P = .0101). Mean changes in Beck Anxiety Inventory (BAI) total score from baseline were significantly greater for SKY than waitlist (ITT mean difference: −5.19; 95% CI −0.93 to −9.34; P = .0097; completer mean difference: −6.23; 95% CI −1.39 to −11.07; P = .0005). No adverse events were reported. Conclusion Results of this randomized, waitlist-controlled pilot study suggest the feasibility and promise of an adjunctive SKY-based intervention for patients with MDD who have not responded to antidepressants.

    2016-12-01

    Pulmonary hypertension (PH) due to left heart disease (LHD), i.e., group 2 PH, is the most common reason for increased pressures in the pulmonary circuit. Although recent guidelines incorporate congenital heart disease in this classification, left-sided heart diseases of diastolic and systolic origin including valvular etiology are the vast majority. In these patients, an increased left-sided filling pressure triggers a multistage hemodynamic evolution that ends into right ventricular failure through an initial passive increase in pulmonary artery pressure complicated over time by pulmonary vasoconstriction, endothelial dysfunction, and remodeling of the small-resistance pulmonary arteries. Regardless of the underlying left heart pathology, when present, PH-LHD is associated with more severe symptoms, worse exercise tolerance, and outcome, especially when right ventricular dysfunction and failure are part of the picture. Compared with group 1 and other forms of pulmonary arterial hypertension, PH-LHD is more often seen in elderly patients with a higher prevalence of cardiovascular comorbidities and most, if not all, of the features of metabolic syndrome, especially in case of HF preserved ejection fraction. In this review, we provide an update on current knowledge and some potential challenges about the pathophysiology and established prognostic implications of group 2 PH in patients with HF of either preserved or reduced ejection fraction.

    ABSTRACT Objective: To characterize the factors that interfere in drug treatment compliance in a group of individuals with arterial hypertension. Methods: A non-experimental descriptive study that analyzed a sample of 80 patients diagnosed with arterial hypertension, who underwent medical treatment and were admitted to a university hospital during the period from March to May 2009. To collect data, the Instrument for Evaluation of Attitudes Regarding Taking Medication was applied. Results: In the studied population, 45.1% had sufficient degree of compliance to drug therapy. Individuals with controlled blood pressure, females, white, single, married or widowed, retired, aged between 40 and 59 years, and those aged above 80 years were the interviewees who answered positively regarding compliance and follow-up of drug therapy. Conclusion: Despite the fact that the number of factors that facilitate the process of compliance to drug treatment is greater than the number of complicating factors, we found that more than half of the patients surveyed had an insufficient degree of compliance with drug treatment for high blood pressure, which demonstrates the need to develop studies aimed to identify these factors and their contribution to the promotion of patient autonomy, acceptance, awareness and adaptation regarding their illness.

    Objective The present study aimed to compare the effects of the dipeptidyl peptidase-4 (DPP-4) inhibitors vildagliptin and saxagliptin on 24 hour acute glucose fluctuations in Chinese patients with type 2 diabetes mellitus (T2DM) inadequately controlled with a combination of metformin and sulfonylurea. Research design and methods This was a 24 week, prospective, randomized, open-label, active-controlled study. Patients (N = 73) with T2DM who had inadequate glycemic control (HbA1c 7.0%-10.0%) with a stable dosage of metformin plus gliclazide for more than 3 months were randomized to receive either vildagliptin 50 mg twice daily (BID, n = 37) or saxagliptin 5 mg once daily (QD, n = 36). Change in mean amplitude of glycemic excursions (MAGE) was assessed at the end of 24 weeks. Results At baseline, the mean (±SD) age was 62.9 ± 6.55 years, disease duration was 7.0 ± 2.33 years, and HbA1c was 8.4 ± 0.68%. After 24 weeks of treatment, the MAGE decreased from 5.81 ± 1.16 mmol/L to 4.06 ± 0.86 mmol/L (p<0.001) in the vildagliptin group and from 5.66 ± 1.14 mmol/L to 4.79 ± 1.25 mmol/L (p = 0.003) in the saxagliptin group. The mean change in MAGE in the vildagliptin group was significantly greater than that in the saxagliptin group (1.74 ± 0.48 mmol/L vs. 0.87 ± 0.40 mmol/L, p<0.001). The mean change in HbA1c, from baseline to the study endpoint, in the vildagliptin and saxagliptin groups, was 1.22 ± 0.40% and 1.07 ± 0.36%, respectively, with no significant difference between the groups (p = 0.091). The overall safety and tolerability of vildagliptin and saxagliptin were similar. The limitations of the study were a small number of patients and open-label administration of the study drug. Conclusion Vildagliptin produced a significantly greater reduction in acute glucose fluctuations compared with saxagliptin when added to a dual combination of metformin and sulfonylurea in Chinese

    2014-01-01

    Background Control of blood pressure is frequently inadequate in spite of availability of several classes of well tolerated and effective antihypertensive drugs. Several factors, including the use of suboptimal doses of drugs, inadequate or ineffective treatments and poor drug compliance may be the reason for this phenomenon. The aim of the current non- randomized study was to evaluate the effectiveness of a Home-Based Telemedicine service in patients with uncontrolled hypertension. Methods 74 patients were enrolled in a Home Based Telemedicine group and 94 patients in the Usual Care group. At baseline and at the end of the study, patients in both groups were seen in a cardiology office. Patients in Home Based Telemedicine group additionally were followed by a physician-nurse, through scheduled and unscheduled telephone appointments. These patients also received a blood pressure measuring device that could transmit the readings to a central data monitor via secure data connection. Results During the study period (80 ± 25 days), a total of 17401 blood pressure measurements were taken in the Home Based Telemedicine group corresponding to 236 ± 136 readings per patient and a mean daily measurement of 3 ± 1.7. The scheduled telephone contacts (initiated by the nurse) equaled to 5.2 ± 4.3/patient (370 in total) and the unscheduled telephone contacts (initiated by the patients) were 0.4 ± 0.9/patient (30 in total). The mean systolic blood pressure values decreased from 153 ± 19 mmHg to 130 ± 15 mmHg (p < 0.0001) at the end of the study and diastolic blood pressure values decreased from 89 ± 10 mmHg to 76 ± 11 mmHg (p < 0.0001). In the Usual Care group, the mean systolic blood pressure values decreased from 156 ± 16 mmHg to 149 ± 17 mmHg (p < 0.05) at the end of the study and diastolic blood pressure values decreased from 90 ± 8 mmHg to 86 ± 9 mmHg (p < 0.05).

    The kinetics of captopril plasma levels and of the drug-induced plasma converting enzyme activity (PCEA), plasma renin activity (PRA) and diastolic blood pressure (DBP) modifications were studied over 24 h after oral administration of captopril, 1 mg/kg, to ten hypertensive patients. Free unchanged captopril pharmacokinetic parameters were: t1/2, alpha: 0.45 +/- 0.06 h; tmax: 0.98 +/- 0.13 h; Cmax: 1.31 +/- 0.20 mg l-1; t1/2,z: 0.66 +/- 0.13 h; V: 0.614 +/- 0.104 1 kg-1 and CLtot: 0.690 +/- 0.082 l h-1 kg-1. At 6 h captopril was no longer detectable in plasma. The onset of PCEA inhibition and of DBP decrease closely followed the rise of captopril's plasma levels, while that of PRA increase was delayed. In contrast, while captopril rapidly disappeared from plasma, its biological and antihypertensive effects were long-lasting. The lack of correlation between the relative bioavailability of captopril and the induced reduction in DBP (evaluated by the corresponding AUCs) suggests that free unchanged captopril plasma monitoring is not an adequate indicator of hypertensive patients' potential responsiveness to captopril's blood pressure lowering effects.

    Pulmonary arterial hypertension is a common and fatal complication of scleroderma that may involve inflammatory and autoimmune mechanisms. Alterations in the gene expression of peripheral blood mononuclear cells have been previously described in patients with pulmonary arterial hypertension. Our goal is to identify differentially expressed genes in peripheral blood mononuclear cells in scleroderma patients with and without pulmonary hypertension as biomarkers of disease. Gene expression analysis was performed on a Microarray Cohort of scleroderma patients with (n=10) and without (n=10) pulmonary hypertension. Differentially expressed genes were confirmed in the Microarray Cohort and validated in a Validation Cohort of scleroderma patients with (n=15) and without (n=19) pulmonary hypertension by RT-qPCR. We identified inflammatory and immune-related genes including interleukin-7 receptor (IL-7R) and chemokine receptor 7 as differentially expressed in patients with scleroderma-associated pulmonary hypertension. Flow cytometry confirmed decreased expression of IL-7R on circulating CD4+ T-cells from scleroderma patients with pulmonary hypertension. Differences exist in the expression of inflammatory and immune-related genes in peripheral blood cells from patients with scleroderma-related pulmonary hypertension compared to those with normal pulmonary artery pressures. These findings may have implications as biomarkers to screen at-risk populations for early diagnosis and provide insight into mechanisms of scleroderma-related pulmonary hypertension. PMID:20973920

    The aim of this study was to investigate whether resistant hypertension differs from uncontrolled and controlled hypertension in terms of target organ damage. Hypertensive subjects with antihypertensive medication (n=385) were identified in a population survey conducted in southwestern Finland. None of the study subjects had previously diagnosed cardiovascular or renal disease or diabetes. Ankle-brachial index, estimated glomerular filtration rate, electrocardiogram-determined left ventricular hypertrophy and cardiometabolic risk factors were assessed. The prevalence of peripheral arterial disease among subjects with resistant, uncontrolled and controlled hypertension was 6/37 (16%), 22/275 (8%) and 0/73 (0%), respectively (P=0.006). There were no differences in the prevalence of renal insufficiency, left ventricular hypertrophy or metabolic parameters between the groups. Resistant hypertension affects vasculature more than uncontrolled hypertension, and thus it can be regarded as a marker of more severe disease.

    The offspring of essential hypertensive parents have been found to exhibit abnormalities in renal hemodynamics and sodium handling before the eventual occurrence of hypertension. The reported abnormalities represent a wide spectrum of changes including increased GFR, normal or decreased RPF, slight increase in blood pressure (although within the normal range), and an exaggerated natriuresis response to a sodium load. The heterogeneity of these abnormalities may reflect the specific conditions of the studies, the lability of the changes, or different subgroups of subjects with genetic predisposition to essential hypertension. Several lines of evidence have suggested a relationship between hypertension and the development of diabetic nephropathy in insulin-dependent diabetics. This laboratory has found that recent-onset insulin-dependent diabetics can exhibit renal hemodynamics abnormalities very early in the course of diabetes according to a positive or negative family history of essential hypertension. These changes include increased GFR and mean arterial pressure, but no differences in renal sodium and lithium handling in diabetics with a genetic predisposition to essential hypertension. In addition, diabetics with a positive family history of essential hypertension exhibited a more-marked vasodilative response to an acute interruption of the renin-angiotensin system, further suggesting inadequate angiotensin modulation of renal vascular tone. The significance of these abnormalities in relation to the development of diabetic nephropathy requires further investigation.

    Idiopathic intracranial hypertension is a disorder of intracerebral pressure regulation and patients run the risk of permanent visual loss. Intracranial hypertension (IH) has been reported rarely in systemic lupus erythematosus (SLE). We reviewed the medical records of 127 patients with lupus nephritis (LN) who were followed up from 1987 to 1996 in our unit. There were six patients with IH which gave a disease prevalence of 4.7% in those with LN. All were females giving a disease prevalence of 5.2% for that sex, a high rate of occurrence of IH in patients with LN. Their age ranged from 22 to 34 y (27.8 +/- 3.6 y). Headache, vomiting and diplopia were the common presenting symptoms and had started 7.3 +/- 4.4 weeks prior to the diagnosis of IH. The cerebrospinal (CSF) opening pressure (413.3 +/- 77.0 mmH2O) was raised in all cases. Biochemical and cytological analyses of CSF were normal. The only abnormal radiological finding was partially empty sella in one patient on magnetic resonance imaging (MRI) (performed in three patients) or computed tomography (CT) (performed in all patients). All patients had serological evidences of active lupus disease at the time of diagnosis of IH. The renal histology was WHO type IV in four cases and III and V in one each indicating severe renal involvement. Laboratory evidences of procoagulant activity were found in the form of positive anticardiolipin antibody (aCL) in two patients, lupus anticoagulant (LA) in two and an otherwise unexplained isolated prolongation of activated partial thromboplastin time (APTT) in the other two. Clinically, one or more episodes of symptomatic venous or arterial thrombosis had occurred in all subjects. In addition to symptomatic measures, all subjects were treated with prednisolone, azathioprine, cyclophosphamide and plasmapheresis according to the protocol of our unit. One patient who did not receive plasmapheresis and cyclophosphamide had a relapse while all others recovered completely. None

    Objective: To assess the incidence, possible risk factors and prognosis of pulmonary arterial hypertension (PAH) in critically ill elderly patients. Methods: We selected 122 cases admitted to the ICU, ages 60–93 years old. An echocardiography examination was performed within four days after admission to the ICU. PAH is usually suspected if the patient’s pulmonary artery systolic pressure ≥ 40 mmHg. We collected echocardiography data, relevant clinical data and routine laboratory data; we then used a statistical method to analyze the risk factors for PAH in critically ill elderly patients and examined its impact on the prognosis. Results: Total 51 patients were diagnosed with PAH. The prevalence of critically ill elderly patients with PAH was 41.8%. The ANOVA analysis showed that if patients had COPD (P = 0.031) and/or respiratory failure (P = 0.021), they were more prone to PAH. An enlarged left atrium (P = 0.038) and/or right ventricle (P = 0.029), a declining left ventricle fractional shortening rate (P = 0.038), and an elevated amount of the brain natriuretic peptides (P = 0.046) were all associated with the occurrence of PAH. Multivariate regression analysis showed that the left atrial diameter (P = 0.045) was the risk factor in critically ill elderly patients with PAH. The 30-day mortality rate was 33.3% for elderly patients with PAH, which is statistically significant (P = 0.035) when compared with the mortality rate of patients with normal pulmonary artery pressure. Our multivariate regression analysis also showed that, for critically ill elderly patients admitted in the ICU, PAH (P = 0.039) is risk factor for increased mortality. Conclusions: A higher incidence of PAH occurs in critically ill elderly patients. PAH is more likely to occur in patients with an enlarged left atrium, and these problems adversely impact the prognosis. PMID:28367167

    Pulmonary Arterial Hypertension (PAH) is a rare and progressive disease with low incidence and prevalence, and elevated mortality. PAH is characterized by increased mean pulmonary artery pressure. The aim of this study was to analyse patients with combined mutations in BMPR2, ACVRL1, ENG and KCNA5 genes and to establish a genotype-phenotype correlation. Major genes were analysed by polymerase chain reaction (PCR) and direct sequencing. Genotype-phenotype correlation was performed. Fifty-seven (28 idiopathic PAH, 29 associated PAH group I) were included. Several mutations in different genes, classified as pathogenic by in silico analysis, were present in 26% of PAH patients. The most commonly involved gene was BMPR2 (12 patients) followed by ENG gene (9 patients). ACVRL1 and KCNA5 genes showed very low incidence of mutations (5 and 1 patients, respectively). Genotype-phenotype correlation showed statistically significant differences for gender (p = 0.045), age at diagnosis (p = 0.035), pulmonary vascular resistance (p = 0.030), cardiac index (p = 0.035) and absence of response to treatment (p = 0.011). PAH is consequence of a heterogeneous constellation of genetic arrangements. Patients with several pathogenic mutations seem to display a more severe phenotype. PMID:27630060

    Forty nine patients with arterial hypertension of stage I-II received combined sanatorium treatment. Of them, 21 had adjuvant total magnetotherapy. All the patients were examined for parameters of central, cerebral hemodynamics and microcirculation. The adjuvant magnetotherapy produced a beneficial effect on hypertension: clinical symptoms attenuated, arterial pressure became more stable, hemodynamics improved, duration of hospitalization reduced, requirement in hypotensive drugs diminished.

    Pulmonary artery pressure (PAP) is known to regress after successful balloon mitral valvotomy (BMV). Data of persistent pulmonary artery hypertension (PPAH) following BMV is scarce. We analyzed the clinical, echocardiographic, and hemodynamic data of 701 consecutive patients who have undergone successful BMV in our institute from 1997 to 2003. Data of 287 patients who had PPAH (defined by pulmonary artery systolic pressure [PASP] of ≥ 40 mmHg at one year following BMV) were compared to the data of 414 patients who did not have PPAH. Patients who had PPAH were older (39.9 ± 9.9 years vs. 29.4 ± 10.1; P < 0.001). They had higher prevalence of atrial fibrillation (AF; 21.9 vs. 12.1%, P < 0.05), moderate or severe pulmonary artery hypertension (PAH) defined as PASP more than 50 mmHg (43.5 vs. 33.8%, P = 0.00), anatomically advanced mitral valve disease as assessed by Wilkin's echocardiographic score > 8 (33.7 vs. 23.2%, P < 0.001), and coexistent aortic valve disease (45.6 vs. 37.9%, P < 0.001) at the baseline. Those patients with PPAH had comparatively lower immediate postprocedural mitral valve area (MVA). On follow-up of more than five years, the occurrence of restenosis (39.3 vs. 10.1%, P = 0.000), new onset heart failure (14% vs. 4%, P < 0.05) and need for reinterventions (9.5% vs. 2.8%, P < 0.05) were higher in the PPAH group. Patients with PPAH were older, sicker, and had advanced rheumatic mitral valve disease. They had higher incidence of restenosis, new onset heart failure, and need for reinterventions on long term follow-up. PPAH represents an advanced stage of rheumatic valve disease and indicates chronicity of the disease, which may be the reason for the poorer prognosis of these patients. Patients with PPAH requires intense and more frequent follow-up. PMID:24015345

    Objectives We wished to evaluate the effects of an antigranulocyte-macrophage colony-stimulating factor monoclonal antibody (KB003) on forced expiratory volume in 1 s (FEV1), asthma control and asthma exacerbations in adult asthmatics inadequately controlled by long-acting bronchodilators and inhaled/oral corticosteroids. Settings 47 ambulatory asthma care centres globally. Primary outcome measures Change in FEV1 at week 24. Participants 311 were screened, 160 were randomised and 129 completed the study. Interventions 7 intravenous infusions of either 400 mg KB003 or placebo at baseline and weeks 2, 4, 8, 12, 16 and 20. Primary and secondary outcome measures FEV1 at week 24, asthma control, exacerbation rates and safety in all participants as well as prespecified subgroups. Main results In the KB003 treated group, FEV1 at week 24 improved to 118 mL compared with 54 mL in the placebo group (p=0.224). However, FEV1 improved to 253 vs 26 mL at week 24 (p=0.02) in eosinophilic asthmatics (defined as >300 peripheral blood eosinophils/mL at baseline) and comparable improvements were seen at weeks 20 (p=0.034) and 24 (p=0.077) in patients with FEV1 reversibility ≥20% at baseline and at weeks 4 (p=0.029), 16 (p=0.018) and 20 (p=0.006) in patients with prebronchodilator FEV1 ≤50% predicted at baseline. There were no effects on asthma control or exacerbation rates. The most frequent adverse events in the KB003 group were rhinosinusitis and headache. There was no significant difference in antidrug antibody response between placebo and treated groups. There were no excess infections or changes in biomarkers known to be associated with the development of pulmonary alveolar proteinosis. Conclusions Higher doses and/or further asthma phenotyping may be required in future studies with KB003. Trial registration number NCT01603277; Results. PMID:26739717

    The pathogenesis of chronic thromboembolic pulmonary hypertension (CTEPH) is unknown. Histopathologic studies revealed that pulmonary vasculature lesions similar to idiopathic pulmonary arterial hypertension (PAH) existed in CTEPH patients as well. It’s well-known that genetic predisposition plays an important role in the mechanism of PAH. So we hypothesized that PAH-causing gene mutation might exist in some CTEPH patients and act as a background to facilitate the development of CTEPH. In this study, we analyzed 7 PAH-causing genes including BMPR2, ACVRL1, ENG, SMAD9, CAV1, KCNK3, and CBLN2 in 49 CTEPH patients and 17 patients recovered from pulmonary embolism (PE) but without pulmonary hypertension(PH). The results showed that the nonsynonymous mutation rate in CTEPH patients is significantly higher than that in PE without PH patients (25 out of 49 (51%) CTEPH patients vs. 3 out of 17 PE without PH patients (18%); p = 0.022). Four CTEPH patients had the same point mutation in ACVRL1 exon 10 (c.1450C>G), a mutation approved to be associated with PH in a previous study. In addition, we identified two CTEPH associated SNPs (rs3739817 and rs55805125). Our results suggest that PAH-causing gene mutation might play an important role in the development of CTEPH.

    Accumulating evidence suggests that altered cellular metabolism is systemic in pulmonary hypertension (PH) and central to disease pathogenesis. However, bioenergetic changes in PH patients and their association with disease severity remain unclear. Here, we hypothesize that alteration in bioenergetic function is present in platelets from PH patients and correlates with clinical parameters of PH. Platelets isolated from controls and PH patients (n = 28) were subjected to extracellular flux analysis to determine oxygen consumption and glycolytic rates. Platelets from PH patients showed greater glycolytic rates than controls. Surprisingly, this was accompanied by significant increases in the maximal capacity for oxygen consumption, leading to enhanced respiratory reserve capacity in PH platelets. This increased platelet reserve capacity correlated with mean pulmonary artery pressure, pulmonary vascular resistance, and right ventricular stroke work index in PH patients and was abolished by the inhibition of fatty acid oxidation (FAO). Consistent with a shift to FAO, PH platelets showed augmented enzymatic activity of carnitine palmitoyltransferase-1 and electron transport chain complex II. These data extend the observation of a metabolic alteration in PH from the pulmonary vascular axis to the hematologic compartment and suggest that measurement of platelet bioenergetics is potentially useful in assessment of disease progression and severity.

  8. What Is in a Name? How Biomedical Language May Derail Patient Understanding of Hypertension.

    2015-07-01

    Despite major advances in treating hypertension, >50% of all individuals diagnosed with the condition remain in poor control. A fundamental issue may be that patients may not fully understand the meaning of the term hypertension or its cause, leading to poor adherence to medications and limiting other effective self-management behaviors. We posit that the word hypertension itself may contribute to these misunderstandings, particularly in regards to the role of stress in causing hypertension, which thus suggests stress management as a primary strategy for control. The word hypertension is often interpreted by patients to mean too much tension. In conjunction with cultural framings of stress causing high blood pressure, many patients turn to stress management to control their hypertension. The word hypertension can thus cause patients to think of it as more of a psychological than physiological condition, thus discounting the value of antihypertensive medications and interfering with medication adherence. We therefore suggest that clinicians reconsider the use of the term hypertension and the ways in which they explain the condition to patients. Reorienting the language to the more patient-centered term of high blood pressure may help patients better understand the condition and to more readily embrace the available efficacious therapies.

    Endothelin receptor antagonists (ERAs) have been shown to improve the prognosis of patients with pulmonary arterial hypertension (PAH). However, the effect of the oral dual ERA bosentan on peripheral endothelial dysfunction (PED), as assessed by flow-mediated vasodilation (FMD), in patients with pulmonary hypertension is not well characterized. We investigated the effect of bosentan on PED in patients with PAH or inoperable chronic thromboembolic pulmonary hypertension (CTEPH). A total of 18 patients with PAH and 8 with CTEPH were treated with bosentan. All patients underwent FMD assessment before and after 3 months of bosentan treatment. Whereas FMD increased from 6.01% ± 2.42% at baseline to 8.07% ± 3.18% after 3 months (P < 0.0001) in patients with PAH, those with CTEPH showed no change in FMD after bosentan therapy. In addition, FMD at baseline showed no correlation with pulmonary vascular resistance (r = 0.09) or plasma brain natriuretic peptide levels (r = -0.23) in patients with PAH. Bosentan treatment ameliorated PED in patients with PAH but not in those with inoperable CTEPH. In addition, FMD did not correlate with PAH severity.

    Background. There are no Canadian prevalence studies on pulmonary arterial hypertension (PAH) to date. We described the characteristics of treated PAH patients and the healthcare utilization and costs associated with PAH in a population of public drug plan beneficiaries in Ontario, Canada. Methods. A retrospective cross-sectional analysis was conducted between April 2010 and March 2011 to identify treated PAH patients using population-based health administrative databases. We investigated demographic and clinical characteristics of treated PAH patients and conducted a cohort study to determine treatment patterns, healthcare utilization, and associated costs, over a one-year follow-up period (March 2012). Results. We identified 326 treated PAH cases in Ontario's publicly funded drug plan. Overall mean age was 59.4 years (±20.3 years) and over 77% of cases were women (n = 251). Combination therapy was used to treat 22.9% (n = 69) of cases, costing an average of $4,569 (SD $1,544) per month. Median monthly healthcare costs were $264 (IQR $96–$747) for those who survived and $2,021 (IQR $993–$6,399) for those who died over a one-year period, respectively (p < 0.01). Conclusions. PAH care in Ontario is complex and has high healthcare costs. This data may help guide towards improved patient management. PMID:27445555

    Background Risk factors may influence the improvement or worsening of erectile dysfunction (ED). The aim of the current study was to evaluate the effect of systemic hypertension on ED in patients with peripheral arterial disease. Methods The effect of hypertension on ED was assessed in 125 consecutive patients in a cross-sectional quantitative study. The ages of the patients ranged from 19 to 88 years old (mean: 59.82 ± 10.48 years). The only exclusion criterion was the amputation of one or both legs. The ankle-arm index was assessed and the international index of ED questionnaire was applied to all participants in the study. Results Of the 125 patients, 22 (17.6%) had mild (grade 1), 50 (40.0%) had moderate (grade 2) and 53 (42.4%) had severe (grade 3) ED. Hypertensive patients have more ED, with ED in hypertensive patients being associated to chronic arterial disease. However, in comparison with normotensive patients, hypertension exerts an immediate protective effect on erectile function. Conclusions In conclusion, although erectile function is initially protected by systemic arterial hypertension in patients with chronic arterial disease, both chronic arterial disease and ED deteriorate over the long term in hypertensive patients.

    2016-09-01

    Resistant hypertension is defined as a blood pressure above 140/90 mmHg despite adherence to a combination of at least three optimally dosed antihypertensive medications, one of which is a diuretic. Chronic kidney disease (CKD) is one of the more common patient comorbidities associated with resistant hypertension. Recommended low-salt diet and triple antihypertensive drug regimens that include a diuretic, should be complemented by the sequential addition of other antihypertensive drugs. CKD is associated with premature vascular ageing, characterized by accelerated arteriosclerosis or atherosclerosis and endothelial dysfunction. Vascular changes appear in the early stages of CKD, although they are most pronounced in advanced stages. Systolic hypertension is the most common form of hypertension in patients with CKD, and raised systolic BP is independently associated with risk of progression to chronic kidney disease. Rigid arterial walls attenuate baroreceptor control of efferent sympathetic activity and vagal activation. Reduced baroreflex sensitivity maintains high sympathetic activity directed to the heart, blood vessels, and kidney, which contributes to high BP. Patients with CKD also have an inadequate vasoconstrictor response to baroreceptor unloading, this contributes to frequent orthostatic hypotension and circulatory instability. Moreover, hypoxemia of renal tissue due to kidney damage activates the CNS via afferent nerves, which also contributes to high sympathetic activity. New therapeutic innovations for resistant hypertension, such as renal denervation and carotid barostimulation are under investigation especially in patients with advanced chronic kidney disease. One of the most common reasons for blood pressure resistance in CKD is volume overload with increased sympathetic activity also being a major contributor. We will focus on the epidemiology as well as pathophysiology and therapeutic approaches to managing resistant hypertension in CKD stages 3

    Prostacyclin improves symptoms, exercise tolerance, and survival in patients with pulmonary arterial hypertension. However, the difficulty of administration (whether intravenous, subcutaneous, or by inhalation) often causes side effects that can reduce the patient's quality of life and which may sometimes be serious. Bosentan, an orally active endothelin receptor antagonist, improves functional class and exercise tolerance in these patients. We describe the successful transition from prostacyclin to bosentan in five patients with severe pulmonary arterial hypertension who suffered serious side effects with prostacyclin treatment.

    Introduction Hypertension is a major modifiable risk factor for cardiovascular and kidney disease, yet the proportion of adults whose hypertension is controlled is low. The patient-centered medical home (PCMH) is a model for care delivery that emphasizes patient-centered and team-based care and focuses on quality and safety. Our goal was to investigate changes in hypertension care under PCMH implementation in a large multipayer PCMH demonstration project that may have led to improvements in hypertension control. Methods The PCMH transformation initiative conducted 118 semistructured interviews at 17 primary care practices in southeastern Pennsylvania between January 2011 and January 2012. Clinicians (n = 47), medical assistants (n = 26), office administrators (n = 12), care managers (n = 11), front office staff (n = 7), patient educators (n = 4), nurses (n = 4), social workers (n = 4), and other administrators (n = 3) participated in interviews. Study personnel used thematic analysis to identify themes related to hypertension care. Results Clinicians described difficulties in expanding services under PCMH to meet the needs of the growing number of patients with hypertension as well as how perceptions of hypertension control differed from actual performance. Staff and office administrators discussed achieving patient-centered hypertension care through patient education and self-management support with personalized care plans. They indicated that patient report cards were helpful tools. Participants across all groups discussed a team- and systems-based approach to hypertension care. Conclusion Practices undergoing PCMH transformation may consider stakeholder perspectives about patient-centered, team-based, and systems-based approaches as they work to optimize hypertension care.

    The excess risk for hypertension in black Americans continues to be a major health concern. Although there is considerable information regarding these disease trends, many of the major underpinnings of the etiology of hypertension remain unclear. The excess mortality in blacks due to heart disease, renal failure, and stroke is clearly directly related to the excess burden of hypertension. Amid the recent findings about the pathophysiology of hypertension, some clear differences in the effects of overweight, salt sensitivity, and vascular biology emerge along ethnic lines. These differences may shed some light on the development of more effective treatment strategies. Based on our current knowledge, aggressive management of hypertension in blacks is critical. This review highlights what is known about various factors affecting hypertension and its treatment in black Americans.

  17. Postmodernity and a hypertensive patient: rescuing value from nihilism.

    PubMed Central

    Smith, S

    1998-01-01

    Much of postmodern philosophy questions the assumptions of Modernity, that period in the history of the Western world since the Enlightment. These assumptions are that truth is discoverable through human reason; that certain knowledge is possible; and furthermore, that such knowledge will provide a basis for the ineluctable progress of Mankind. The Enlightenment project is underwritten by the conviction that knowledge gained through the scientific method is secure. In so far as biomedicine inherits these assumptions it becomes fair game for postmodern deconstruction. Today, perhaps more than ever, plural values compete, and contradictory approaches to health, for instance, garner support and acquire supremacy through consumer choice and media manipulation rather than evidence-based science. Many doctors feel a tension between meeting the needs of the patient face to face, and working towards the broader health needs of the public at large. But if the very foundations of medical science are questioned, by patients, or by doctors themselves, wherein lies the value of their work? This paper examines the issues that the anti-foundationalist thrust of postmodernism raises, in the light of a case of mild hypertension. The strict application of medical protocol, derived from a nomothetic, statistical perspective, seems unlikely to furnish value in the treatment of an individual. The anything goes, consumerist approach, however, fares no better. The author argues that whilst value cannot depend on any rationally predetermined parameters, it can be rescued, and emerges from the process of the meeting with the patient. PMID:9549679

    Abstract The age at diagnosis of pulmonary arterial hypertension (PAH) and the prevalence of cardiovascular (CV) risk factors are increasing. We sought to determine whether the response to drug therapy was influenced by CV risk factors in PAH patients. We studied consecutive incident PAH patients (n = 146) between January 1, 2008, and July 15, 2011. Patients were divided into two groups: the PAH–No CV group included patients with no CV risk factors (obesity, systemic hypertension, type 2 diabetes mellitus, permanent atrial fibrillation, mitral and/or aortic valve disease, and coronary artery disease), and the PAH-CV group included patients with at least one. The response to PAH treatment was analyzed in all the patients who received PAH drug therapy. The PAH–No CV group included 43 patients, and the PAH-CV group included 69 patients. Patients in the PAH–No CV group were younger than those in the PAH-CV group (P < 0.0001). In the PAH–No CV group, 16 patients (37%) improved on treatment and 27 (63%) did not improve, compared with 11 (16%) and 58 (84%) in the PAH-CV group, respectively (P = 0.027 after adjustment for age). There was no difference in survival at 30 months (P = 0.218). In conclusion, in addition to older age, CV risk factors may predict a reduced response to PAH drug therapy in patients with PAH.

    The age at diagnosis of pulmonary arterial hypertension (PAH) and the prevalence of cardiovascular (CV) risk factors are increasing. We sought to determine whether the response to drug therapy was influenced by CV risk factors in PAH patients. We studied consecutive incident PAH patients (n = 146) between January 1, 2008, and July 15, 2011. Patients were divided into two groups: the PAH-No CV group included patients with no CV risk factors (obesity, systemic hypertension, type 2 diabetes mellitus, permanent atrial fibrillation, mitral and/or aortic valve disease, and coronary artery disease), and the PAH-CV group included patients with at least one. The response to PAH treatment was analyzed in all the patients who received PAH drug therapy. The PAH-No CV group included 43 patients, and the PAH-CV group included 69 patients. Patients in the PAH-No CV group were younger than those in the PAH-CV group (P < 0.0001). In the PAH-No CV group, 16 patients (37%) improved on treatment and 27 (63%) did not improve, compared with 11 (16%) and 58 (84%) in the PAH-CV group, respectively (P = 0.027 after adjustment for age). There was no difference in survival at 30 months (P = 0.218). In conclusion, in addition to older age, CV risk factors may predict a reduced response to PAH drug therapy in patients with PAH.

    In recent times, the prevalence of pulmonary arterial hypertension (PAH) is more commonly seen among elderly populations. The increased prevalence of hypertension, diabetes, obesity, arterial stiffness, as well as diastolic dysfunction, may cause endothelial dysfunction and affect pulmonary vasculature. Furthermore, older patients have certain differences in clinical characteristics and outcomes. In this article, the special characteristics of aging in PAH patients have been reviewed, while the risk predictors of elderly patients are also discussed. PMID:28270839

    The study involved 153 patients (92 females, 61 males aged 30-75 years) with arterial pressure from 120/80 to 180/100 mm Hg. The role of dentist in primary diagnosis of hypertension was identified. The study highlights the need for functional status assessment before dental treatment and the importance of safe and effective local anesthesia for the patients with arterial hypertension. The paper presents rationale for the choice of local anesthetic agent for these patients.

    Propranolol induced changes in blood plasma chemistry were followed in thirty hypertensive patients (WHO I-II) who were seen each week during 14-15 weeks. The initial 4 weeks were a drug free period and the next 2 weeks were a drug adjustment period. After that the patients were on an unchanged propranolol dose for 8 weeks (40, 80 or 160 mg four times daily). For all observed changes the correlation was studied to (1) dose, (2) free and total simultaneously determined plasma concentration and (3) free and total average plasma concentration of unchanged drug during the preceding 24 h period. Total protein and albumin did not change significantly. After 4 and 8 weeks on the final dose orosomucoid was increased significantly (by 10%) compared with the value from the end of the drug free period. Creatinine rose significantly during the initial 4-6 weeks therapy to remain at the same level during the last 4 weeks. Urate was increased at the two lowest dose levels. Total cholesterol fell significantly (5%) while triglycerides increased significantly (16%). T4 rose significantly, T3 fell and r-T3 rose significantly in a dose dependent way. Interindividually r-T3 was the only biochemical change showing a significant relationship to the propranolol plasma concentration. The relationship reached the highest level of significance to the average 24 h free concentration.

    A randomized comparative study was performed to evaluate the control of hypertension with use of home blood pressure measurement (HBPM) and casual blood pressure measurement, and analyze the white coat effect. Hypertensive patients in primary health care units were randomly divided into two groups: group I, participating of the educational activities and group II that followed the routine treatment. The hypertensive patients from group I realized HBPM at the beginning and the end of the study. White-coat effect was evaluated by the difference between the casual blood pressure measurement and HBPM. The study included 290 hypertensive patients, but realized HBPM 82 hypertensive patients. There was increase in blood pressure control from the beginning to end of study in hypertensive patients from group I (p < 0.05) measured by HBP (60% to 68.3%) and casual measurement (62% to 71%) and in group II, HMBP hypertension control was higher than the casual blood pressure measurement (63% vs 50%). The white coat effect was greater in hipertensive patients from group II.

    Abstract Hypertensive patients in neurosurgery are becoming more common, which increased the risk of surgical stress response. Meanwhile, the relationship between hypertension and anesthesia methods is unclear on the stress response. The purpose of this study is to compare the effect of different anesthesia methods on high-sensitivity C-reactive protein (Hs-CRP), blood glucose, and leucocyte levels in neurosurgical patients with hypertension or normal. Eighty neurosurgical patients were randomly divided into 4 groups (n = 20): balanced anesthesia group (A), balanced anesthesia with hypertension group (B), total intravenous anesthesia group (C), total intravenous anesthesia with hypertension group (D). The levels of Hs-CRP, blood glucose, leucocyte count, and neutrophil percentage and were detected at before anesthesia (T0), during anesthesia (T1), 2 hours post anesthesia (T2), 24 hours post anesthesia (T3). Patients with hypertension had higher Hs-CRP expression, blood glucose, and neutrophil percentage at time T0 than those of normal, but not leucocyte count. At time T3, patients with hypertension in D group had lower Hs-CRP expression than those in B group (P < 0.01). Patients with normal in C group had lower Hs-CRP expression (P < 0.01), blood glucose (P < 0.05), and leukocyte count (P < 0.05) than those in A group. Both hypertension history and anesthesia method had significant effects on the Hs-CRP expression, blood glucose, and leukocyte count. Total intravenous anesthesia decreases Hs-CRP expressions more efficiently than balanced anesthesia in neurosurgical patients with hypertension or normal. Moreover, total intravenous anesthesia can availably reduce the perioperative stress response by attenuating the increase of blood glucose and leukocyte count in normal tensive patients.

    Increased pressure in the pulmonary circulation, or pulmonary hypertension, is a common disorder that may complicate various cardiopulmonary conditions, including severe obstructive airways disease and left ventricular dysfunction. An increase in pulmonary arterial pressure that is not due to coexistent cardiopulmonary disease, known as pulmonary arterial hypertension, may occur in the absence of a demonstrable cause (idiopathic or familial); as a complication of systemic conditions, such as connective tissue disease, HIV infection, or chronic liver disease; or as a result of the use of fenfluramine anorexigens, amphetamines, or cocaine. The development of disease-specific therapies for pulmonary arterial hypertension over the past decade underscores the importance of diagnosing pulmonary hypertension early in the course of the condition and implementing a treatment strategy that is based on the condition's cause and severity. In this review, the authors present approaches to the diagnosis and management of pulmonary arterial hypertension, using a hypothetical case to highlight the key management points.

    Background. To simplify traditional Chinese medicine syndrome differentiation and allow researchers to master syndrome differentiation for hypertension, this paper retrospectively studied the literature and analyzed syndrome elements corresponding to hypertension syndromes. Methods. Six databases including PubMed, EMBASE, Chinese Bio-Medical Literature Database, Chinese National Knowledge Infrastructure, Chinese Scientific Journal Database, and Wan-fang Data were searched from 1/January/2003 to 30/October/2013. We included all clinical literature testing hypertension syndromes and retrospectively studied the hypertension literature published from 2003 to 2013. Descriptive statistics calculated frequencies and percentages. Results. 13,272 patients with essential hypertension were included. Clinical features of hypertension could be attributed to 11 kinds of syndrome factors. Among them, seven syndrome factors were excess, while four syndrome factors were deficient. Syndrome targets were mainly in the liver and related to the kidney and spleen. There were 33 combination syndromes. Frequency of single-factor syndromes was 31.77% and frequency of two-factor syndromes was 62.26%. Conclusions. Excess syndrome factors of hypertension patients include yang hyperactivity, blood stasis, phlegm turbidity, internal dampness, and internal fire. Deficient syndrome factors of hypertension patients are yin deficiency and yang deficiency. Yin deficiency with yang hyperactivity, phlegm-dampness retention, and deficiency of both yin and yang were the three most common syndromes in clinical combination. PMID:24660016

    This study analyzed the cost-effectiveness of a patient hypertension education intervention that provided patient education through interactive voice response technology and distribution of automated blood pressure monitors to high-risk plan members with uncontrolled hypertension. A total of 17,318 members were identified with hypertension in an administrative database. The study sample consisted of all 534 high-risk hypertensive plan members who received blood pressure monitors. Using data on activity-based program costs and changes in hypertension control, this study modeled the intervention's cost-effectiveness relative to no intervention. The intervention was estimated to have brought hypertension under control in 151 patients during the study year. Across all 534 participants in 1 year, 0.3 events (acute myocardial infarction, stroke, congestive heart failure, and renal failure) were avoided and 2.77 life-years were gained (LYG). The incremental cost-effectiveness ratio (ICER) for the intervention compared with no intervention was $767 per person brought under control or $41,927 per LYG. If the gains in hypertension control from 1 year's investment were assumed to last 10 years, the 10-year ICER relative to no intervention was $1857 per LYG. The intervention is a cost-effective strategy to address hypertension and can serve as a model for future innovations.

  14. Hypertension and hypertensive encephalopathy.

    The definition of hypertension has continuously evolved over the last 50 years. Hypertension is currently defined as a blood pressure greater than 140/90mmHg. One in every four people in the US has been diagnosed with hypertension. The prevalence of hypertension increases further with age, affecting 75% of people over the age of 70. Hypertension is by far the most common risk factor identified in stroke patients. Hypertension causes pathologic changes in the walls of small (diameter<300 microns) arteries and arterioles usually at short branches of major arteries, which may result in either ischemic stroke or intracerebral hemorrhage. Reduction of blood pressure with diuretics, β-blockers, calcium channel blockers, and angiotensin-converting enzyme (ACE) inhibitors have all been shown to markedly reduce the incidence of stroke. Hypertensive emergency is defined as a blood pressure greater than 180/120mmHg with end organ dysfunction, such as chest pain, shortness of breath, encephalopathy, or focal neurologic deficits. Hypertensive encephalopathy is believed to be caused by acute failure of cerebrovascular autoregulation. Hypertensive emergency is treated with intravenous antihypertensive agents to reduce blood pressure by 25% within the first hour. Selective inhibition of cerebrovascular blood vessel permeability for the treatment of hypertensive emergency is beginning early clinical trials.

    Few conditions make even the most experienced pediatric anesthesiologists take pause. Pulmonary hypertension is one such condition due to the associated high perioperative morbidity and mortality. Much is written about the intraoperative management of pediatric pulmonary hypertension. This article will instead focus on postoperative care and review the evidence in support of a risk stratification approach for the post-anesthetic disposition of these patients. The total risk for post-anesthetic adverse events includes the patient's baseline risk factors and the incremental risks imposed by the procedure and anesthetic. A proposal with recommendations to guide practitioners and a table summarizing relevant factors are provided. Last, the readers' attention is drawn to the heterogeneity of pulmonary hypertensive disease. Pulmonary arterial hypertension (precapillary) differs significantly from pulmonary venous hypertension (postcapillary); the anesthetic management for one may be relatively contraindicated in the other. Their dissimilarities justify the need to distinguish them for study and research endeavors.

    This study attempted to clarify the differences in blood pressure (BP) between the office (clinic) and home settings in patients with controlled, sustained, masked or white-coat hypertension. The following formula was used: office mean systolic BP (omSBP)-mean morning home SBP (mmhSBP)/office mean diastolic BP (omDBP)-mean morning home DBP (mmhDBP). The paired t-test was used for statistical analysis. The omSBP-mmhSBP/omDBP-mmhDBP calculation yielded the following results: among normotensive subjects, -1.1±11.2/-1.7±8.5 mm Hg (mean SBP and mean DBP were higher at home than in the office; n=451, P=0.038 in SBP, P=0.000 in DBP); in controlled hypertensive patients, -0.42±10.9/-2.2±8.2 mm Hg (n=1362, P=0.160 in SBP, P=0.000 in DBP); among sustained hypertensive patients, 5.6±14.7/0.048±9.9 mm Hg (n=1370, P=0.000 in SBP, P=0.857 in DBP); in masked hypertensive patients, -15.3±12.9/-9.3±9.5 mm Hg (n=1308, both P=0.000); and among white-coat hypertensive patients, 23.7±13.2/8.2±9.1 mm Hg (n=580, both P=0.000). Our results showed a difference of 5 mm Hg in SBP among sustained hypertensive patients, as recommended by the Japanese Society of Hypertension Guidelines for the Management of Hypertension; however, in other hypertensive patient types, the differences in SBP and DBP between office and home measurements differed by >5 mm Hg. Office and home BP measurements should be interpreted cautiously, keeping in mind the clinical setting.

    Hypertensive diabetes individuals are at higher risk for cardiovascular events and progression to end stage renal disease. Several well conducted clinical trials indicate that aggressive treatment of hypertension in individual with diabetes reduces these complications. Combinations of two or more antihypertensive drugs are frequently required to reach the target blood pressure and to improve the cardiovascular and renal outcomes in these patients. There are physiological and clinical rationales for renin-angiotensin system blockade in hypertensive diabetics. Trandolapril/verapamil sustained released (SR) is a fixed-dose combination of trandolapril and a sustained release formulation of verapamil and indicated in treatment of hypertension in patients who require more than one drug to reach target blood pressure. The antihypertensive efficacy of trandolapril/verapamil SR has been evaluated extensively in large trials. In the INVEST trial, a verapamil SR-based treatment strategy that included trandolapril in most patients was effective in reducing the primary outcome in hypertensive patients with coronary artery disease. The new onset of diabetes was also significantly lower in the verapamil SR/trandolapril treatment group in comparison with those on the atenolol/hydroclorothiazide treatment group. The BErgamo NEphrologic DIabetes Complications Trial (BENEDICT) documented that in hypertensive diabetes and normoalbuminuria, trandolapril plus verapamil or trandolapril alone delayed the onset of microalbuminuria independent of their blood pressure-reducing effect. Thus, trandolapril/verapamil is an effective option for treatment of hypertensive diabetes patients requiring more than one agent to achieve target blood pressure. PMID:17969376

    The aim of this study was to measure the percentage of patients with hypertension, treated hypertension and controlled hypertension, using data collected over one week by 235 general practitioners well representative of the French medical population and selected by SOFRES Médical. Practitioners had to carry out their own survey over a period of one week on all patients above 18 years of age who visited their office. They were initially instructed to use the same type of mercury sphygmomanometer, equiped with the same pneumatic cuffs of different sizes. Three consecutive blood pressure measurements were effected, the last two were recorded. Patients were considered as hypertensive if the mean of the two recorded BP measurements was > or = 140-90 mmHg, or < 140-90 mmHg under pharmacological treatment. Hypertensive patients were considered as controlled when their blood pressure levels were overall < 140-90 mmHg under treatment. According to age, two other control levels were analysed: blood pressure < 160-95 mmHg before 65 years and blood pressure < 160-90 mmHg at 65 years or more. Among 12,351 patients, 5,020 are hypertensive (4%), 2,985 under pharmacological treatment (59%) and 2,035 without treatment (4%). Among untreated patients, 9% had an hypertension above the borderline values. Before 65 years, 28% had an under treatment blood pressure < 140-90 mmHg and 71% < 160-95 mmHg. Among 65 years or more hypertensive patients, 21% had an under treatment blood pressure < 140-90 mmHg and 60% < 160-90 mmHg. Before 65 years, 25% among patients with a monotherapy remained with a blood pressure > 160-95 mmHg and 34% with a blood pressure > 160-90 mmHg among those of 65 years or more; 230 patients (5%) remained in high risk with a blood pressure > 180-105 mmHg. 176 untreated and 54 despite their treatment. This study carried out in French medical practice yield two main conclusions regarding the management of hypertension: as the prevalence of hypertensive patients is 41

    The molecular pharmacological effects of cytoflavin in patients with hypertensive encephalopathy (HE) and isolated systolic arterial hypertension (ISAH) have been investigated using the following methods: assessment of complaints, 24-hour arterial pressure monitoring, ultrasound diagnostics including echocardiography, measurement of lipid profiles and coagulograms, and molecular phenotyping by MALDI-TOF/TOF-MS. A combination of cytoflavin administration with standard therapy of HE and ISAH led to the most expressed return development of clinical symptoms, restoration of the hemodynamic, structural, and geometrical parameters of cardiovascular system, and normalization of the indices of lipid profiles and coagulograms in comparison to patients with HE and ISAH, which accepted only standard therapy. Molecular mechanisms of cytoflavin action have been revealed, which include control of the activity of cellular signaling pathways by means of intermolecular interactions. The optimized therapy of HE and ISAH is recommended for clinical application, which assumes a combined use of standard therapy and cytoflavin and provides a geroprotective action upon the cardiovascular system.

    Purpose: Percutaneous hemodialysis thrombectomy causes subclinical pulmonary emboli without short-term clinical consequence; the long-term effects on the pulmonary arterial vasculature are unknown. We compared the prevalence of pulmonary hypertension between patients who underwent one or more hemodialysis access thrombectomy procedures with controls without prior thrombectomy.Methods: A retrospective case-control study was performed. Cases (n = 88) had undergone one or more hemodialysis graft thrombectomy procedures, with subsequent echocardiography during routine investigation of comorbid cardiovascular disease. Cases were compared with controls without end-stage renal disease (ESRD) (n = 100, group 1), and controls with ESRD but no prior thrombectomy procedures (n = 117, group 2). The presence and velocity of tricuspid regurgitation on echocardiography was used to determine the prevalence and grade of pulmonary hypertension; these were compared between cases and controls using the chi-square test and logistic regression.Results: The prevalence of pulmonary hypertension among cases was 52% (46/88), consisting of mild, moderate and severe in 26% (n = 23), 10% (n = 9) and 16% (n = 14), respectively. Prevalence of pulmonary hypertension among group 1 controls was 26% (26/100), consisting of mild, moderate and severe pulmonary hypertension in 14%, 5% and 7%, respectively. Cases had 2.7 times greater odds of having pulmonary hypertension than group 1 controls (p = 0.002). The prevalence of pulmonary hypertension among group 2 controls was 42% (49/117), consisting of mild, moderate and severe pulmonary arterial hypertension in 25% (n = 49), 10% (n = 12) and 4% (n = 5), respectively. Cases were slightly more likely to have pulmonary hypertension than group 2 controls (OR = 1.5), although this failed to reach statistical significance (p = 0.14).Conclusion: Prior hemodialysis access thrombectomy does not appear to be a risk factor for pulmonary arterial hypertension

    Endothelial dysfunction is related to reduced arterial elasticity in patients with essential hypertension. Circulating endothelial progenitor cells (EPCs), an important endogenous repair approach for endothelial injury, is altered in hypertensive patients. However, the association between alteration in circulating EPCs and hypertension-related reduced arterial elasticity has not been reported. The purpose of this study is to investigate the association between alteration in circulating EPCs and hypertension-related reduced arterial elasticity. We measured the artery elasticity profiles including brachial-ankle PWV (baPWV) and C1 large and C2 small artery elasticity indices in patients with essential hypertension (n = 20) and age-matched normotensive subjects (n = 21). The number and activity of circulating EPCs isolated from peripheral blood were determined. Compared to normotensive subjects, the patients with hypertension exhibited decreased C1 large and C2 small artery elasticity indices, as well as increased baPWV. The number of circulating EPCs did not differ between the two groups. The migratory and proliferative activities of circulating EPCs in hypertensive patients were lower than those in normotensive subjects. Both proliferatory and migratory activities of circulating EPCs closely correlated with arterial elasticity profiles, including baPWV and C1 large and C2 small artery elasticity indices. Multivariate analysis identified both proliferative and migratory activities of circulating EPCs as independent predictors of the artery elasticity profiles. The present study demonstrates for the first time that impaired activity of circulating EPCs is associated with reduced arterial elasticity in patients with hypertension. The fall in endogenous repair capacity of vascular endothelium may be involved in the pathogenesis of hypertension-related vascular injury.

    Patients with a life-limiting diagnosis of pulmonary arterial hypertension (PAH) or chronic thromboembolic pulmonary hypertension (CTEPH) need disease-specific information, ability to cope, and functioning social networks. This cohort study investigated the experiences of PAH and CTEPH patients who received information about their diagnosis, treatment, and management, in addition to coping and social support. Sixty-eight adult patients (mean ± SD, age 67 ± 14; 66% women) were included. A total of 54% of the patients wanted more information. Patients received information mostly in areas concerning medical test procedures, the diagnosis, disease severity, possible disease causes, and how to manage their disease. Coping ability was significantly better in patients who were satisfied with the received information (P = 0.0045). The information given to PAH or CTEPH patients and their communication with healthcare professionals can be greatly improved. Gaps in information and misunderstandings can be avoided by working in cooperation with the patients, their relatives, and within the PAH team. PMID:25374462

    An increased expression of transient receptor potential canonical type 3 (TRPC3) cation channels has been proposed as one of the factors contributing to the pathogenesis of hypertension. To test that hypothesis we compared the expression of TRPC3 and TRPC6 as an endogenous control in human vascular endothelium of preglomerular arterioles in kidney biopsies from six patients with malignant hypertension and from four patients with diarrhea-associated hemolytic-uremic syndrome. Patients with malignant hypertension showed significantly higher systolic blood pressure and more prominent expression of TRPC3 in vascular endothelium of preglomerular arterioles compared to patients with hemolytic-uremic syndrome. The expression of TRPC6 was not different between the two groups. The study supports the hypothesis that the increased expression of TRPC3 is associated with malignant hypertension in humans.

    Summary Background Hypertension is a powerful risk factor for cardiovascular disease and frequently occurs in conjunction with obesity. Accumulative evidence suggests a link between inflammation and hypertension. The aim of study was to evaluate whether blood pressure, obesity and smoking may influence acute-phase response. Material/Methods Ninety-two patients with essential hypertension and 75 healthy volunteers as a control group were studied. In all subjects assessment of hsCRP, α1-acid glycoprotein (AGP), α1-antichymotrypsin, transferrin, α1-antitrypsin, and C3 and C4 complement were performed. Evaluation of glycosylation profile and reactivity coefficient (RC) for AGP was done by means of affinity immunoelectrophoresis with concanavalin A as a ligand. Results When compared to the controls, hypertensive subjects presented significantly higher hsCRP concentrations and lower transferrin level. Hypertensive patients had elevated AGP-AC. The intensification of the inflammatory reaction was greater in the subgroup of hypertensive patients smoking cigarettes. In obese hypertensives, elevated serum C3 complement level was found. Conclusions We conclude that arterial hypertension may evoke the acute-phase response in humans. Markers of acute-phase response are particularly strongly expressed in smokers. Serum C 3 complement, but not other APPs, is elevated in hypertension coexisting with obesity. PMID:22534714

    The sudden change in vision is a medical emergency that must be evaluated immediately to rule out important institutions as systemic vasculitis or ischemic stroke. Its association with hypertensive crisis makes it necessary to rule out accelerated-malignant hypertension, which is accompanied by other retinal disorders (exudates and hemorrhages) and adrenal involvement. Nonarteritic anterior ischemic optic neuropathy (AION) is another entity to consider, as is it not uncommon in the young (12.7% in a series of 848 cases). Its association with hypertension has been described in 32% of cases.

    The incidence of ischemic heart disease has been increased rapidly in Korea. However, the clinical effects of antecedent hypertension on acute myocardial infarction have not been identified. We assessed the relationship between antecedent hypertension and clinical outcomes in 7,784 patients with acute myocardial infarction in the Korea Acute Myocardial Infarction Registry during one-year follow-up. Diabetes mellitus, hyperlipidemia, cerebrovascular disease, heart failure, and peripheral artery disease were more prevalent in hypertensives (n=3,775) than nonhypertensives (n=4,009). During hospitalization, hypertensive patients suffered from acute renal failure, shock, and cerebrovascular event more frequently than in nonhypertensives. During follow-up of one-year, the incidence of major adverse cardiac events was higher in hypertensives. In multi-variate adjustment, old age, Killip class ≥III, left ventricular ejection fraction <45%, systolic blood pressure <90 mmHg on admission, post procedural TIMI flow grade ≤2, female sex, and history of hypertension were independent predictors for in-hospital mortality. However antecedent hypertension was not significantly associated with one-year mortality. Hypertension at the time of acute myocardial infarction is associated with an increased rate of in-hospital mortality. PMID:19794974

    We report three patients with colonic variceal bleeding secondary to portal hypertension, 0.5% of all cases with hemorrhagic portal hypertension studied by us in the last 16 years. One patient had idiopathic portal hypertension, and the others had extrahepatic portal vein thrombosis. Colonic varices were documented in all three cases by angiogram; large arteriovenous fistulas in the territory of the superior mesenteric artery and between the inferior mesenteric artery and hemorrhoidal veins were demonstrated in one patient. Two patients underwent colonoscopy; colonic varices were seen in only one. Two patients also had bled from esophagogastric varices. One patient underwent descending colon and sigmoid resection after failure to control bleeding with ligation of arterial supply; one patient underwent the Sugiura procedure, plus transanal ligation of hemorrhoids and rectal varices. At 3 months, 2 years, and 4 years of follow-up, the patients were in good general condition without any evidence of rebleeding.

    The effect of anapriline, corinfar and reserpine on parameters of hemodynamics and plasma testosterone was evaluated in 60 juvenile hypertension patients who achieved pronounced hypotensive response. It was established that the level of sex hormones tended to diminution by the end of the treatment month 1 or 2, this drop being more noticeable in reserpine administration. Basing on this evidence it would be beneficial for patients suffering from juvenile hypertension in need of chemotherapy to take courses of the above drugs.

    Hypertension is common in renal transplant patients and sometimes very difficult to control. Refractory hypertension can adversely affect renal graft and patient survival. Many antihypertensive medications are not well tolerated or can have important drug interactions with immunosuppressive medications. These drugs can cause significant side effects including fluid depletion, azotemia, electrolyte imbalance, and anemia. Bilateral native nephrectomy in renal transplant patients has been reported to be beneficial in controlling severe hypertension. We report five patients with severe hypertension despite as many as 9 different antihypertensive medications. All patients had previous kidney or simultaneous kidney pancreas transplantation. Each of our patients underwent laparoscopic bilateral native nephrectomy. Renal function varied from creatinine of 1.4–2.4, and the number of antihypertensive medications from 3 to 9 at the time of nephrectomy surgery. Mean arterial blood pressure improved in all five patients at 3–6 months post nephrectomy, the number of antihypertensive medications decreased in 4, but renal function remained stable at 3–6 months in only 3 patients. We found laparoscopic bilateral native nephrectomy to be beneficial in renal and simultaneous kidney pancreas transplant patients with severe and refractory hypertension. Our patients with better baseline renal allograft function at time of nephrectomy received the most benefit. No decrease in allograft function could be attributed to acute rejection. PMID:26348394

    Decreased capillary density influences vascular resistance and perfusion. The authors aimed to investigate the influence of the renin-angiotensin receptor blocker valsartan on retinal capillary rarefaction in hypertensive patients. Retinal vascular parameters were measured noninvasively and in vivo by scanning laser Doppler flowmetry before and after 4 weeks of treatment with valsartan in 95 patients with hypertension stage 1 or 2 and compared with 55 healthy individuals. Retinal capillary rarefaction was determined with the parameters intercapillary distance (ICD) and capillary area (CapA). In hypertensive patients, ICD decreased (23.4±5.5 μm vs 21.5±5.6 μm, P<.001) and CapA increased (1564±621 vs 1776±795, P=.001) after valsartan treatment compared with baseline. Compared with healthy normotensive controls (ICD 20.2±4.2 μm, CapA 1821±652), untreated hypertensive patients showed greater ICD (P<.001) and smaller CapA (P=.019), whereas treated hypertensive patients showed no difference in ICD (P=.126) and CapA (P=.728). Therapy with valsartan for 4 weeks diminished capillary rarefaction in hypertensive patients.

    BACKGROUND: As part of a recent project focused on needs-based planning for generalist physicians, the authors documented the variety of practice styles of primary care physicians for managing patients with hypertension. They investigated the validity of various explanations for these different styles and the relative contributions of physician and patient characteristics to the rates at which hypertensive patients contact physicians. METHODS: Retrospective descriptive study using regression analyses to simultaneously adjust for the influence of key patient and physician characteristics. Hypertensive patients in Winnipeg were identified using Manitoba physician claims data for fiscal years 1993/94 and 1994/95. Patients were included if they were 25 years of age or more and had at least one physician contact in both 1993/94 and 1994/95 during which hypertension was diagnosed. In addition, the primary care physician had to be the physician that the patient contacted most frequently in 1993/94 and 1994/95 and with whom she or he had at least 2 visits during this period. Only patients of family practitioners whose practice included at least 50 hypertensive patients were included. RESULTS: To control for the effects of large samples and to validate the results, the authors conducted all analyses for half (6282) the sample of hypertensive patients who met the study criteria (12,563). A total of 132 primary care physicians who met the study criteria were identified. The patients made on average 9.3 ambulatory visits to physicians (both general practitioners and specialists) in 1994/95. Those who had more complex medical conditions (i.e., were formally referred to a specialist), those who had 3 or more serious medical problems and those who had been admitted to hospital made more visits to their primary care physician than those without these characteristics. After these and other key patient characteristics were controlled for, a primary care physician's patient recall

    Idiopathic pulmonary arterial hypertension is characterized by progressive increase in pulmonary arterial pressure and pulmonary vascular resistance which lead to right ventricular failure and death. Pregnancy in patients with idiopathic pulmonary arterial hypertension is contraindicated because of the high maternal and fetal mortality. The authors present a case of successful pregnancy and delivery of a patient with idiopathic pulmonary arterial hypertension in Hungary for the first time. The aim of the report was to demonstrate that management and treatment of idiopathic pulmonary arterial hypertension in a pregnant woman is a complex and multidisciplinary task that should involve obstetrician, cardiologist and anesthesiologist. Those patients who become pregnant and do not wish to terminate the pregnancy must be referred to obstetric centers where a multidiciplinary approach is taken.

    BACKGROUND Hypertension is common in patients with atrial fibrillation (AF) and is an important cause of stroke. OBJECTIVES To determine how effectively hypertension is managed among specialist-treated outpatients with AF. METHODS Investigators reviewed the charts of patients with a diagnosis of AF cared for by medical specialists to determine the change in blood pressure, patterns of antihypertensive drug use and the role of the specialist in the management of hypertension. RESULTS Of 209 patients with AF, 118 had a history of hypertension or an office blood pressure greater than 140/90 mmHg. Blood pressure was measured at 73% of all visits. Hypertension was identified as an important problem in 57% of patients and antihypertensive therapy was either initiated or suggested in 77%. One year after the initial specialist visit, systolic blood pressure was significantly lower (140±20 mmHg at one year versus 148±23 mmHg initially; P=0.015); however, there was no change in diastolic blood pressure (80±12 mmHg at one year versus 81±16 mmHg initially; P=0.602) and only 50% of patients had a blood pressure less than 140/90 mmHg. In contrast, the percentage of patients receiving warfarin increased from 46% to 78% (P=0.0001). CONCLUSIONS In patients treated by specialists for AF, systolic blood pressure is significantly reduced during follow-up; however, 50% of patients continue to have suboptimal blood pressure control. In many patients, hypertension is not identified as an important comorbid illness and antihypertensive therapy is neither recommended nor initiated by the specialist. Greater specialist involvement in the identification and treatment of hypertension in patients with AF could lead to an important, additional reduction in stroke. PMID:16685312

    The relationship between 24-h recumbent blood pressure levels and secretory patterns of catecholamines was investigated in 4 patients with pseudohypoparathyroidism (PsHP) and hypertension and in 9 patients with essential hypertension. A clear circadian rhythm of blood pressure and catecholamines was documented in both groups with lowest levels of blood pressures and catecholamines occurring during sleep. During the 24-h period of recumbency mean arterial blood pressure (MAP) was correlated (r = 0.63, p less than or equal to 0.01) with plasma norepinephrine (N) in the patients with essential hypertension, but this correlation was weaker in patients with PsHP (r = 0.38, p less than or equal to 0.05). MAP was more closely related to plasma epinephrine (E) (r = 0.62, p less than or equal to 0.01) than to plasma NE in patients with PsHP. Plasma NE and E levels were considerably lower in patients with PsHP than in patients with essential hypertension throughout the 24-h recumbent period. The sleep-related decline in blood pressure and NE was less than in patients with essential hypertension. These results suggest that while the sympathetic nervous system may have a role in hour-to-hour maintenance of blood pressure in patients with PsHP and hypertension, it does not appear to be responsible for the elevated arterial pressure in these patients. Factors other than those investigated, such as obesity, alterations in sodium homeostasis of refractoriness of the vascular smooth muscle to the vasodilatory effect of PTH may be involved in the pathogenesis of hypertension in PsHP.

    There is no general consensus on possible factors associated with microalbuminuria in hypertensive patients nor any reported study about this issue in Chinese patients. To examine this issues, 944 hypertensive patients were enrolled in a study based on a cross-sectional survey conducted in Southern China. Multivariate regression analyses were performed to identify the factors related with the presence of microalbuminuria and urinary excretion of albumin. The prevalence of microalbuminuria in hypertensive and non-diabetic hypertensive patients were 17.16% and 15.25%, respectively. Body mass index (BMI), but not waist circumference (WC), were independently associated with microalbuminuria and the values of urinary albumin to creatinine ratio (ACR) based on multiple regression analyses, even after excluding diabetic patients and patients taking inhibitors of the renin-angiotensin system from the analyses. Furthermore, patients with obesity (BMI ≥28) had higher levels of ACR, compared with those with normal weight (BMI <24 kg/m2) and overweight (24 kg/m2≤ BMI < 28). In conclusion, BMI, as a modifiable factor, is closely associated with microalbuminuria among Chinese hypertensive patients, which may provide a basis for future development of intervention approaches for these patients.

    Cardiovascular risk factors in people on antiretroviral treatment (ART) are poorly documented in resource-constrained settings. A cross-sectional study was conducted in 2009 to assess prevalence of diabetes and hypertension in a sample of 242 HIV-infected patients who had initiated ART between 1998 and 2002 in Dakar, Senegal (ANRS 1215 observational cohort). World Health Organization (WHO) criteria were applied to diagnose diabetes and hypertension. Multiple logistic regressions were used to identify factors associated with diabetes and hypertension. Patients had a median age of 46 years and had received ART for a median duration of about 9 years. 14.5% had diabetes and 28.1% had hypertension. Long duration of ART (≥119 months), older age, higher body mass index (BMI), and higher levels of total cholesterol were associated with higher risks of diabetes. Older age, higher BMI at ART initiation, and higher levels of triglycerides were associated with higher risk of hypertension. This study shows that diabetes and hypertension were frequent in these Senegalese HIV patients on ART. It confirms the association between duration of ART and diabetes and highlights the need to implement programs for prevention of cardiovascular risk factors in HIV patients from resource-constrained settings.

    Introduction: Arterial hypertension is the main independent risk factor for cardiovascular (CV) disease and death. It affects development and course of cerebrovascular insult (CVI) and chronic kidney disease (CKD). Balneotherapy with sulphide baths was administered to patients having stage I hypertension (BP values 140-159/90-99), with no arrhythmia or pronounced coronary disease. Baths also had advantage in patients having hypertension joined with obesity, diabetes, microangiopathy, and atherosclerosis of peripheral arteries. Goal: Determine the effects of sulphate-sulphide mineral baths on stage I hypertension after 10 days therapy. Materials and methods: Patients having stage I hypertension were sent to “Mlječanica” Institute for rehabilitation. All subjects were treated with kinesitherapy and electrotherapy, while experimental group (n=30) was also treated with 20 minute baths, daily, for period of 10 days. Results: In experimental group BP level lowered in average 10 mmHg after 10-day therapy, and change was evident even after only 5 days. Conclusion: Sulphate-sulphide mineral water “Mlječanica” caused significant (p<0.05) lowering of arterial BP level after 10 days of therapy in patients who had stage I hypertension. PMID:25685078

    Background The diagnosis of chronic obstructive pulmonary disease (COPD) is often delayed until later stages of the disease. The purpose of the present study was to determine the prevalence of COPD among adults on treatment for systemic arterial hypertension independently of the presence of respiratory symptoms. Methods This cross-sectional study included adults aged ≥40 years with tobacco/occupational exposure and systemic arterial hypertension diagnosed at three Primary Health Care facilities in Goiania, Brazil. Patients were evaluated using a standardized respiratory questionnaire and spirometry. COPD prevalence was measured considering the value of forced vital capacity and/or forced expiratory volume in 1 second <0.70. Results Of a total of 570 subjects, 316 (55%) met inclusion criteria and were invited to participate. Two hundred and thirty-three (73.7%) patients with arterial hypertension reported at least one respiratory symptom, while 83 (26.3%) reported no respiratory symptoms; 41 (17.6%) patients with arterial hypertension and at least one respiratory symptom, and 10 (12%) patients with arterial hypertension but no respiratory symptoms were diagnosed with COPD (P=0.24). The prevalence of COPD in people with no previous COPD diagnosis was greater among those with no respiratory symptoms (100%) than among those with respiratory symptoms (56.1%) (P=0.01). Conclusion Our findings suggest that regardless of the presence of respiratory symptoms, individuals aged ≥40 years with tobacco/occupational exposure and arterial hypertension may benefit from spirometric evaluation.

    The objective was to observe the aspects of nursing appointments undergone by hypertensive patients. This is a descriptive study, developed in three healthcare centers in the city of Fortaleza. The subjects were 13 nurses, and data collection comprised the observation of three of each nurse's appointments, followed by an interview with this professional. It was observed that, during the anamnesis, the previous treatment, the ingestion of hypertensive substances and the existence of associated risk factors were identified. Inspections of the patient's appearance, blood pressure and weight were also evident. The identified categories were: aspects of the nurse's role in basic healthtcare; treatment of hypertension and day-to-day difficulties of people with this disease. We conclude that many aspects are not being approached during the nursing appointments, which can result in a low-quality healthcare service provided for people cared for the hypertension program in these basic healthcare centers.

    Inadequate minerals intake, as well as disruption of some metabolic processes in which microelements are cofactors, are suggested to lead to the development of hypertension. The role of minerals in the pathogenesis of hypertension still remains to be explained. In the present study, we sought to determine associations between serum and hair mineral concentrations and serum lipids and glucose levels. Forty obese hypertensive subjects with insulin resistance and 40 healthy volunteers were recruited in the study. Blood pressure, BMI, and insulin resistance were recorded in all subjects. Levels of lipids, glucose, sodium and potassium, iron, copper, zinc, magnesium, and calcium were assessed in serum. Iron, copper, zinc, magnesium, and calcium were assessed in hair. Dietary intake of the analyzed minerals was estimated. We found distinctly higher concentrations of serum iron and serum and hair calcium as well as markedly lower levels of hair zinc in the hypertensive subjects. The study group manifested also significantly lower daily intake of calcium, magnesium, and iron. We observed a relationship between the concentrations of iron, zinc, and copper in serum and hair and high and low range of cholesterol, triglycerides, and glucose serum levels in the studied patients. Moreover, this study demonstrated significant correlation between serum and hair concentrations of selected minerals and their dietary intake and levels of serum lipids and glucose and blood pressure in the study and the control groups. The obtained results seem to indicate the association between lipid and glucose metabolism and iron, copper, zinc, and calcium concentrations in blood and hair of hypertensive and obese patients with insulin resistance.

    At early stages of essential hypertension (EH) clinical psychological examinations of 96 EH patients revealed predominance of anxiety-hypochondriac responses controlled by will. Changes in cortical neurodynamics were evident from a decline in attention concentration. At EH stage II persistent hypertension and prolonged psychogenias gave rise to psychic disadaptation occurring as anxious-depressive conditions. Damage to cortical neurodynamics brought about mnestic and thinking disorders.

    Introduction We aimed to inform the design of behavioral interventions by identifying patients’ and their family members’ perceived facilitators and barriers to hypertension self-management. Materials and methods We conducted focus groups of African American patients with hypertension and their family members to elicit their views about factors influencing patients’ hypertension self-management. We recruited African American patients with hypertension (n = 18) and their family members (n = 12) from an urban, community-based clinical practice in Baltimore, Maryland. We conducted four separate 90-minute focus groups among patients with controlled (one group) and uncontrolled (one group) hypertension, as well as their family members (two groups). Trained moderators used open-ended questions to assess participants’ perceptions regarding patient, family, clinic, and community-level factors influencing patients’ effective hypertension self-management. Results Patient participants identified several facilitators (including family members’ support and positive relationships with doctors) and barriers (including competing health priorities, lack of knowledge about hypertension, and poor access to community resources) that influence their hypertension self-management. Family members also identified several facilitators (including their participation in patients’ doctor’s visits and discussions with patients’ doctors outside of visits) and barriers (including their own limited health knowledge and patients’ lack of motivation to sustain hypertension self-management behaviors) that affect their efforts to support patients’ hypertension self-management. Conclusion African American patients with hypertension and their family members reported numerous patient, family, clinic, and community-level facilitators and barriers to patients’ hypertension self-management. Patients’ and their family members’ views may help guide efforts to tailor behavioral

    Objectives This phase III study evaluated the efficacy and safety of rituximab plus methotrexate (MTX) in patients with active rheumatoid arthritis (RA) who had an inadequate response to MTX and who were naïve to prior biological treatment. Methods Patients with active disease on stable MTX (10–25 mg/week) were randomised to rituximab 2×500 mg (n=168), rituximab 2×1000 mg (n=172), or placebo (n=172). From week 24, patients not in remission (Disease Activity Score (28 joints) ≥2.6) received a second course of rituximab; patients initially assigned to placebo switched to rituximab 2×500 mg. The primary end point was American College of Rheumatology 20 (ACR20) response at week 24. All patients were followed until week 48. Results At week 24, both doses of rituximab showed statistically superior efficacy (p<0.0001) to placebo (ACR20: 54%, 51% and 23%; rituximab (2×500 mg) + MTX, rituximab (2×1000 mg) + MTX and placebo + MTX, respectively). Secondary end points were also significantly improved for both rituximab groups compared with placebo. Further improvements in both rituximab arms were observed from week 24 to week 48. Rituximab + MTX was well tolerated, demonstrating comparable safety to placebo + MTX through to week 24, and between rituximab doses through to week 48. Conclusions Rituximab (at 2×500 mg and 2×1000 mg) plus MTX significantly improved clinical outcomes at week 24, which were further improved by week 48. No significant differences in either clinical or safety outcomes were apparent between the rituximab doses. PMID:20488885

    This study aimed to investigate the influence of dexmedetomidine (DEX) on the tourniquet related responses in hypertension patients receiving unilateral knee arthroplasty (UKA) under general anesthesia. Results showed that the incidence of tourniquet induced hypertension (TIH), hemodynamics, MAC and EtSEV in DEX group were significantly lower than those in control group, regardless of hypertension. However, significant differences in TIH, hemodynamics, minimum alveolar concentration (MAC) and end-tidal sevoflurane (EtSEV) were not observed between hypertension patients and non-hypertension patients in both control group and DEX group. Moreover, oxygen index (OI) and respiratory index (RI) remained unchanged after deflation and DEX failed to affect OI and RI within 30 min after deflation, regardless of hypertension. Taken together, DEX may significantly improve the hemodynamics, which is independent of pre-existing hypertension.

    Many studies have reported the negative effects of depression on adherence to antihypertensive medication. However, little is known about the mechanism underlying this relationship in elderly patients with hypertension. The aim of this cross-sectional study is to examine the mediating role of self-efficacy in the relationship between depression and medication adherence among older patients with hypertension. The data were collected from October to December 2014. A total of 255 older patients with hypertension were assessed using the Geriatric Depression Scale, the Self-efficacy for Appropriate Medication Use Scale, and the Morisky Medication Adherence Scale. Hierarchical linear regression analysis and the Sobel test were used to examine the mediating role of self-efficacy in the relationship between depression and medication adherence. Depression and self-efficacy were statistically significant predictors of medication adherence in older patients with hypertension. Self-efficacy partially mediated the relationship between depression and medication adherence. Interventions targeting self-efficacy could increase the confidence of patients in their ability to actively take their medicines. Moreover, health care providers should be aware of the importance of early detection of depression in older patients with hypertension. Future studies with longitudinal data are warranted to clarify the multidirectional relationships between depression, self-efficacy, and medication adherence.

    Pulmonary arterial hypertension (PAH) is associated with a change in vascular architecture. A characteristic histological feature is the plexiform lesion. Similar alterations are observed in the pulmonary vascular bed of patients with chronic thromboembolic pulmonary hypertension (CTEPH). Cytokines involved in angiogenesis were found in both serum and lung tissue of patients with PAH and CTEPH, although their role in the formation of plexiform lesions remains unclear. The examination of breath condensate is a noninvasive technique to analyse proteins possibly associated with the pathogenesis of various lung diseases.Breath condensate of 22 patients with pulmonary hypertension (PAH: n = 12; CTEPH: n = 10) and 7 healthy volunteers was examined using a multiplex fluorescent bead immunoassay to determine the concentrations of the biomarkers angiogenin, bFGF, VEGF, IL-8, and TNF-α. Significantly higher levels of angiogenin, bFGF and TNF-α were observed in breath condensate of patients with pulmonary hypertension in comparison to healthy controls. Similarly, breath condensate levels of VEGF were elevated in patients with PAH as against healthy volunteers. However, IL-8 levels in breath condensate did not differ between the two groups. The data suggest that breath condensate of patients with pulmonary hypertension is characterized by increased levels of the angiogenic factors angiogenin, VEGF and bFGF as well as TNF-α, but not IL-8. A larger study is needed to confirm these results and to determine the prognostic and therapeutic implications of these findings.

    Background. Complementary and alternative medicine (CAM) therapies are being widely used by hypertensive patients worldwide. However, evidences regarding CAM use by hypertensive patients in Ethiopia are limited. This study aimed at assessing prevalence and correlates of CAM use among hypertensive patients attending ambulatory clinic at Gondar University Referral Hospital (GURH), Ethiopia. Methods. A cross-sectional study was employed on 423 patients visiting GURH. Descriptive statistics and bivariate and multivariate logistic regression tools were used to analyze/come up with the prevalence and correlates of CAM use. Results. The prevalence of CAM use in our study was found to be 67.8% and herbal based medicine was the most commonly utilized CAM therapies. Majority of CAM users (70.2%) did not disclose CAM use for their physician. However, nearly half of CAM users (48.4%) were satisfied with the result of CAM use. Conclusions. The higher prevalence of CAM use among hypertensive patients coupled with a very low disclosure rate to their health care providers can have a marked potential to cause ineffective hypertensive management and adverse effects due to CAM use. Health care providers should be open to discussing the use of CAM with their patients as it will lead to better health outcome. PMID:27843480

    In array signal processing, the covariance matrix used to calculate the adaptive weights is often poor estimated when the snapshot number is inadequate. The prior environmental knowledge can be used to make the estimation more accuracy. In this paper, an alternative knowledge-aided adaptive beamforming approach that is robust to low sample support environment is proposed. In this algorithm the covariance matrix used to calculate the optimum weights is constructed by blending a sample covariance matrix and a priori structured covariance matrix. Numerical simulations demonstrate the proposed algorithm has the potential for substantial performance improvement.

    Various forms of cardiac arrhythmias have been documented in hypertensive subjects, and hypertension is an important risk factor for the development of atrial and ventricular arrhythmias and sudden death. Electrocardiography at rest easily documents significant arrhythmias in patients, and this study was carried out to determine the types and frequency of arrhythmias in hypertensive subjects at first presentation in the Hypertension Clinics of the University of Nigeria Teaching Hospital (UNTH) Enugu, Nigeria. The study was hospitalbased and retrospective in nature. The resting 12lead ECG reports of 346 consecutive hypertensive subjects seen at the Hypertension clinics of the UNTH Enugu over a 14 month period were retrieved from the case files and studied. Other information obtained from the case files included the age and gender of the subjects. The mean age of the subjects was 57.3 years. Ninety-five of the subjects had arrhythmias representing 27% of the study population, out of which fifty-five were males (57.9%) and forty were females (42.1%). However 26.9% of all the male subjects had arrhythmias while 28.2% of all the females had arrhythmias. Multiple ventricular ectopics, sinus tachycardia, sinus bradycardia and atrial fibrillation were the most prevalent arrhythmias. This study showed that a significant proportion of hypertensive subjects present initially with significant rhythm disturbances.

    Introduction. Several biomedical findings have established the effects of hypertension on haemostasis and roles of blood coagulation products in the clinical course of hypertension. Methods. This cross-sectional study aimed at determining effects of hypertension on prothrombin time (PT) and activated partial thromboplastin time (APTT) in hypertensive patients in comparison with normotensive subjects attending a tertiary hospital in Calabar. Forty-two (42) hypertensive patients and thirty-nine (39) normotensive control subjects were investigated for PT and APTT using Quick one-stage methods. Results. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) correlated positively with APTT (r = 0.3072, r = 0.4988; P < 0.05) in hypertensive patients. DBP, SBP, PT, and APTT were significantly higher in hypertensive patients when compared to normotensive subjects (P < 0.05). DBP correlated negatively with duration of illness (r = -0.3097; P < 0.05) in hypertensive patients and positively with age of normotensive subjects (r = 0.3523; P < 0.05). Conclusion. The results obtained indicated that measurements of PT and APTT may serve as indices for evaluating hemostatic abnormalities in hypertensive patients and guide for antihypertensive therapy. However, to have better understanding of hemostatic activities in hypertension, it is recommended to conduct D-dimer, platelet factors, and protein assays.

    In patients with newly diagnosed untreated grade I-II hypertension, EEG oscillations were recorded under conditions activation of the two basic motivational systems, defensive motivational system and positive reinforcement system, evoked by recall of personally meaningful emotional events. The 64-channel EEG and cardiovascular reactivity (beat-by-beat technology) were simultaneously recorded. At rest, hypertensive patients had significantly reduced platelet serotonin concentrations in comparison with healthy individuals. The patients experiencing emotional activation were characterized by significantly lower intensity of positive emotions associated with more pronounced suppression of EEG activity in the delta (2-4 Hz) and theta (ranges of frequency 4-6 and 6-8 Hz) oscillators in the parieto-occipital cortex (zones P and PO) in both hemispheres of the brain. The findings attest to insufficient function of the brain serotonin system and hypoactivation of the reward/reinforcement system in patients with primary hypertension.

    Disturbance of trace element balance increases the risk of cerebrovascular disease and, above all, ischemic stroke (IS). A comparative analysis of clinical and demographic parameters and trace element composition of hair was performed in the group of 30 ischemic stroke patients with arterial hypertension (AH) and 30 stroke patients without hypertension (mean age 55±7 years). The stroke patients with hypertension were characterized by the elevated body mass index (28.5±4.1 kg/m2, AI, 26.0±2.9 kg/m2, p=0.006), higher incidence of coronary heart disease (p=0.04). Alcohol consumption more than 3 drinks a week was associated with a 5-fold increase of the risk of stroke with hypertension (95% CI 1.0-27, p=0.035). The results revealed a number of statistically significant differences in trace element profile in the studied groups of patients: deficits of essential magnesium, manganese, cobalt, copper, zinc, a statistically significant increase in sodium levels, toxic and conditionally toxic trace elements (cadmium, mercury, bismuth, barium, etc.). One of the probable factors that lead to the accumulation of toxic trace elements in stroke patients is the increased consumption of alcohol including that of substandard quality. The data obtained also show the feasibility of implementing screening programs to assess micronutrient status (including trace elements) for early detection of pathological abnormalities in the elemental homeostasis that might lead to an increased risk of ischemic stroke and hypertension.

    Pulmonary arterial hypertension is a severe disease with a complex pathogenesis, for which combination therapy is an attractive option.This study aimed to assess the impact of sequential combination therapy on both short-term responses and long-term outcomes in a real-world setting.Patients with idiopathic/heritable pulmonary arterial hypertension, or pulmonary arterial hypertension associated with congenital heart disease or connective tissue disease and who were not meeting treatment goals on either first-line bosentan or sildenafil monotherapy, were given additional sildenafil or bosentan and assessed after 3-4 months. Double combination therapy significantly improved clinical and haemodynamic parameters, independent of aetiology or the order of drug administration. Significant improvements in functional class were observed in patients with idiopathic/heritable pulmonary arterial hypertension. The 1-, 3- and 5-year overall survival estimates were 91%, 69% and 59%, respectively. Patients with pulmonary arterial hypertension associated with connective tissue disease had significantly poorer survival rates compared to other aetiologies (p<0.003).The favourable short-term haemodynamic results and good survival rates, observed in patients receiving both bosentan and sildenafil, supports the use of sequential combination therapy in patients failing on monotherapy in a real-world setting.

    Background: Anxiety, depression, and other adverse psychological reactions are often observed in elderly hypertensive patients. Appropriate exercise is a safe form of adjuvant therapy without causing side effects among these patients, with consistent effects on patients’ mental health. In this study, a collective exercise intervention experiment was conducted to evaluate the mental health of elderly hypertensive patients and to verify the effect of the psychological intervention of collective exercise. Method: A total of 115 elderly hypertensive patients aged 60–70 years old were selected as study subjects from May 2012 to January 2015 in Fuzhou City, Fujian Province, China. A total of 57 patients were included in the control group and 58 patients were assigned in the experimental group. Patients in the experimental group participated in a 12 weeks exercise intervention, while patients in the control group didn’t participate in any regular physical exercise. Results: After intervention, the Symptom Checklist-90 (SCL-90), total score, somatization, obsessive-compulsive symptom, interpersonal sensitivity, depression, anxiety, hostility, and paranoia scores of the experimental group were significantly lower than those of the control group (P < 0.05). The positive coping style score of the experimental group was significantly higher than that of the control group (P<0.05); by contrast, the negative coping style score of the experimental group was significantly lower than that of the control group (P < 0.05). Conclusion: The mental health level and coping ability of elderly hypertensive patients can be effectively improved with the proposed treatment. PMID:27141493

    Background: The patients that are subjects to oral-surgical interventions produce large amounts of steroids in comparison with healthy patients which are not a subject to any dental intervention. The aim of research was to determine the level of stress hormone cortisol in serum, arterial blood pressure and arterial pulse, and to compare the effectiveness of the usage of lidocaine with adrenalin in comparison with lidocaine without adrenalin during the tooth extraction. Patients and methods: This clinical research includes patients with indication of tooth extraction divided in hypertensive and normotensive patients. Results: There is no important statistical distinction between groups, for the cortisol levels before, during and after tooth extraction regardless of the type of anesthetic used, while we registered higher values of systolic and diastolic values at hypertensive patients, regardless of the type of anesthetic Conclusion: There is significant systolic and diastolic blood pressure rise in both groups of patients hypertensive and normotensive patients, (regardless of anesthetic used with or without vasoconstrictor), who underwent tooth extraction. The special emphasize is attributed to hypertensive patients where these changes are more significant. As per cortisol level and pulse rate, our results indicate no significant statistical difference in between groups. PMID:26005263

    Among anesthetic agents used in neurosurgery xenon appears to be the most advantageous. It preserves arterial blood pressure, assures rapid recovery and neuroprotection. But the data is lacking on xenon effect upon cerebral blood flow under anesthetic conditions. We measured flow velocity in middle cerebral artery in neurosurgical patients without intracranial hypertension during closed circuit xenon anesthesia comparing propofol and xenon effect in the same patients. In our study xenon didn't seem to induce clinically relevant changes in cerebral blood flow and preserved cerebral vascular reactivity thus proving its safety in patients without intracranial hypertension.

    Hypertension in Turner syndrome (TS) is a multifactorial, highly prevalent and significant problem that warrants timely diagnosis and rigorous treatment. The objective of this study was to investigate the association between abnormal aortic arch morphology and hypertension in adult TS patients. This was a single centre retrospective study in 74 adult TS patients (age 29.41 ± 8.91 years) who underwent a routine cardiac MRI. Patients were assigned to the hypertensive group (N = 31) if blood pressure exceeded 140/90 mmHg and/or if they were treated with antihypertensive medication. Aortic arch morphology was evaluated on MRI images and initially assigned as normal (N = 54) or abnormal (N = 20), based on the curve of the transverse arch and the distance between the left common carotid-left subclavian artery. We additionally used a new more objective method to describe aortic arch abnormality in TS by determination of the relative position of the highest point of the transverse arch (AoHP). Logistic regression analysis showed that hypertension is significantly and independently associated with age, BMI and abnormal arch morphology, with a larger effect size for the new AoHP method than for the classical method. TS patients with hypertension and abnormal arch morphology more often had dilatation of the ascending aorta. There is a significant association between abnormal arch morphology and hypertension in TS patients, independent of age and BMI, and not related to other structural heart disease. We suggest that aortic arch morphology should be included in the risk stratification for hypertension in TS and propose a new quantitative method to express aortic arch morphology.

    Purpose Insulin resistance plays a role in the development of dementia and hypertension. We investigated a possible relationship between cognitive impairment and insulin resistance in elderly Chinese patients with primary hypertension. Materials and Methods One hundred and thirty-two hypertensive elderly patients (>60 years) were enrolled in this study, and assigned into either the cognitive impairment group (n=61) or the normal cognitive group (n=71). Gender, age, education, body mass index (BMI), waist hip ratio (WHR), total cholesterol (TC), triglyceride (TG), C-reactive protein (CRP), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), creatinine (Cr), fasting plasma glucose (FPG), fasting insulin (FINS), homeostasis model of assessment for insulin resistance index (HOMA-IR), systolic blood pressure, diastolic blood pressure, smoking history, atherosclerosis and the proportion of uncontrolled hypertension were compared between the two groups. Multi-factorial logistic regression analysis was performed. Results No significant differences were found in gender, age, TC, CRP, HDL-C, LDL-C, Cr, BP, smoking history, atherosclerosis and the proportion of uncontrolled hypertension between the two groups. The cognitive impairment group had lower education levels, and higher BMI, WHR, TG, FPG, FINS, and HOMA-IR levels than the control group. Logistic regression analysis revealed the levels of education, BMI, WHR, and HOMA-IR as independent factors that predict cognitive impairment in patients. Conclusion Our study demonstrates that poor education and increased BMI, WHR, and HOMA-IR are independent risk factors for cognitive impairment in elderly patients with hypertension. Insulin resistance plays an important role in the development of cognitive impairment in primary elderly hypertensive patients. PMID:25510751

    Endothelin-1 (ET-1) is one of the most potent vasoconstrictors known to date. While its plasma or serum concentrations are elevated in some forms of experimental and human hypertension, this is not a consistent finding in all forms of hypertension. Matrix metalloproteinases -2 and -9 (MMP-2 and MMP-9), which degrade collagen type IV of the vascular basement membrane, are responsible for vascular remodeling, inflammation, and atherosclerotic complications, including in type 2 diabetes (T2D). In our study, we compared concentrations of ET-1, MMP-2, and MMP-9 in pre-hypertensive (PHTN) and hypertensive (HTN) T2D patients with those of healthy normotensive controls (N). ET-1, MMP-2, and MMP-9 were measured by ELISA. Concentrations of ET-1 in PHTN and N were very similar, while those in HTN were significantly higher. Concentrations of MMP-2 and MMP-9 in PHTN and HTN were also significantly higher compared to N. An interesting result in our study is that concentrations of MMP-2 and MMP-9 in HTN were lower compared to PHTN. In conclusion, we showed that increased production of ET-1 in patients with T2D can lead to long-lasting increases in blood pressure (BP) and clinical manifestation of hypertension. We also demonstrated that increased levels of MMP-2 and MMP-9 in pre-hypertensive and hypertensive patients with T2D mainly reflect the early vascular changes in extracellular matrix (ECM) turnover.

    The aim of this study was to evaluate the effect of aging on the changes to the structure and function of coronary arteries in senile elderly patients with essential hypertension. Patients (aged 60-80 years) were divided into three groups. The 195 hypertensive patients were divided into four sub-groups according to the duration of hypertension. The changes to the coronary arteries (left and right) of all those patients were tested using the following index by 64 coronary computed tomography (CT) scans. The 24 h systolic blood pressure (SBP) and other blood biochemical parameters were assayed for all patients. We found that the value of the body mass index (BMI), total cholesterol (TC) and low density lipoproteins (LDL) were lower, but age and high density lipoproteins (HDL) were higher in the group of very elderly patients with hypertension (Group I; P<0.05) compared with those of a group of elderly patients with hypertension (Group III). The left anterior descending branch calcification score (CSLAD), total calcification score (CST), pulse pressure (PP), the left main branch calcification score (CSLM), the left circumflex branch calcification score (CSLCX) were significantly increased in Group I compared with Group III (P<0.01 and P<0.05, respectively). In addition, the 24 h SBP value for Group I was higher than in the 'very elderly without hypertension' group (Group II). Hence, in elderly patients, a decrease in the levels of BMI, HDL, TC and LDL accompanies aging. Furthermore, the decline of arterial compliance and increase in arterial stiffness develops with age. Aging is more likely to lead to atherosclerosis in the coronary arteries, particularly in the left main coronary artery and its main branches. Aging is an uncontrollable risk factor, which plays a crucial role in coronary artery atherosclerosis.

    DEFINITION, PATHOPHYSIOLOGY, THERAPY: The hypertensive crisis is characterized by a massive, acute rise in blood pressure. Patients with underlying hypertensive disease usually have an increase in systolic blood pressure values > 220 mmHg and diastolic values > 120 mmHg. The severity of the condition, however, is not determined by the absolute blood pressure level but by the magnitude of the acute increase in blood pressure. Thus, in the presence of primarily normotensive baseline values (such as those in eclampsia), even a systolic blood pressure > 170 mmHg may lead to a life-threatening condition. The most important causes are non-compliance (reduction or interruption of therapy), inadequate therapy, endocrine disease, renal (vessel) disease, pregnancy and intoxication (drugs). The management of this condition greatly depends on whether the patient has a hypertensive crisis with organ manifestation (hypertensive emergency) or a crisis without organ manifestation (hypertensive urgency). By documenting the medical history, the medical status and by simple diagnostic procedures, the differential diagnosis can be established at the emergency site within a very short period of time. In the absence of organ manifestations (hypertensive urgency) the patient may have non-specific symptoms such as palpitations, headache, malaise and a general feeling of illness in addition to the increase in blood pressure. In a hypertensive urgency the patient's blood pressure should not be reduced within a few minutes but within a period of 24 to 48 hours. Such adjustment can be achieved on an out-patient basis, however, only if the patient can be followed up adequately for early detection of a renewed attack. In the absence of follow-up facilities, the patient's blood pressure should be reduced over a period of 4 to 6 hours, if necessary in an out-patient emergency service. While intravenous medication is given preference when a rapid effect is desired, oral medication may be used for

    Vascular calcification (VC) is a highly regulated ectopic mineral deposition process involving immune cell infiltration in the vasculatures, which has been recognized to be promoted by hypertension. The matricellular glycoprotein osteopontin (OPN) is strongly induced in myeloid cells as a potential inflammatory mediator of vascular injury. This study aims to examine whether OPN is involved in the regulation of macrophage activation and osteoclast formation in hypertensive subjects with VC. We firstly found an increased proportion of CD11c+CD163- pro-inflammatory peripheral monocytes in hypertensive subjects with VC compared to those without VC by flow cytometric analysis. Primary cultured macrophages from hypertensive subjects with VC also showed altered expression profile of inflammatory factors and higher serum OPN level. Exogenous OPN promoted the differentiation of peripheral monocytes into an alternative, anti-inflammatory phenotype, and inhibited macrophage-to-osteoclast differentiation from these VC patients. In addition, calcified vessels showed increased osteoclasts accumulation accompanied with decreased macrophages infiltration in the of hypertensive subjects. Taken together, these demonstrated that OPN exerts an important role in the monocytes/macrophage phenotypic differentiation from hypertensive patients with VC, which includes reducing inflammatory factor expression and attenuating osteoclast formation.

    Hypertension is a severe threat to human being's health due to its association with many comorbidities. Many research works have explored hypertension's prevalence and treatment. However, few considered impact of patient's socioeconomic status and geographical disparities. We intended to fulfill that research gap by analyzing the association of the prevalence of hypertension and three important comorbidities with various socioeconomic and geographical factors. We also investigated the prevalence of those comorbidities if the patient has been diagnosed with hypertension. We obtained a large collection of medical records from 29 hospitals across China. We utilized Bayes' Theorem, Pearson's chi-squared test, univariate and multivariate regression methods and geographical detector methods to analyze the association between disease prevalence and risk factors. We first attempted to quantified and analyzed the spatial stratified heterogeneity of the prevalence of hypertension comorbidities by q-statistic using geographical detector methods. We found that the demographic and socioeconomic factors, and hospital class and geographical factors would have an enhanced interactive influence on the prevalence of hypertension comorbidities. Our findings can be leveraged by public health policy makers to allocate medical resources more effectively. Healthcare practitioners can also be benefited by our analysis to offer customized disease prevention for populations with different socioeconomic status. PMID:28367080

    Dobutamine stress testing is increasingly used for the diagnosis and functional evaluation of coronary artery disease. The aim of this study was to assess the hemodynamic profile, safety, and feasibility of dobutamine stress testing in hypertensive patients. Dobutamine (up to 40 micrograms/kg per minute)-atropine (up to 1 mg) stress echocardiography was performed for the detection of myocardial ischemia in 1164 patients with limited exercise capacity (age, 60 +/- 12 years; 761 men); 446 patients were known to have hypertension. The test was considered feasible when 85% of the maximal heart rate and/or an ischemic end point (new or worsened wall motion abnormalities, ST segment depression, or angina) was achieved. No myocardial infarction or death occurred during the test. Dobutamine induced a significant increase of heart rate in patients with and without hypertension (59 +/- 25 and 63 +/- 23 beats per minute, respectively). Peak rate pressure product was similar in patients with and without hypertension (18,566 +/- 4584 and 18,230 +/- 4508). Hypotension (systolic pressure drop > 40 mm Hg) during the test was more frequent in hypertensive patients (7% versus 4% in normotensive, P < .05). Independent predictors of hypotension were baseline systolic pressure greater than 140 mm Hg (odds ratio, 6.9; 95% confidence interval, 3.4 to 14), older age (odds ratio, 1.04; 95% confidence interval, 1.01 to 1.07), and medication with calcium channel blockers (odds ratio, 1.8; 95% confidence interval, 1.1 to 3.5). The prevalence of ventricular tachycardia was similar (4.1%) in both groups. Episodes of 10 beats or more (0.06% of patients) were terminated promptly by intravenous metoprolol administration. Dobutamine stress testing was considered feasible in 91% of patients with and 92% of patients without hypertension. Dobutamine-atropine stress echocardiography is a safe and feasible method for the assessment of hypertensive patients referred for evaluation of myocardial ischemia

    Background and Purpose: Despite the increased use and availability of magnetic resonance imaging (MRI), its role in hypertensive intracerebral hemorrhage (ICH) remains uncertain. In this retrospective study, we assessed the utility of MRI in diagnosis and management of patients with hypertensive ICH. Methods: We retrospectively reviewed the charts of patients with ICH presenting to our hospital over an 18-month period. We included patients who presented with hypertensive ICH in typical locations and excluded lobar hemorrhages. We further isolated cases that had undergone MRI. Collected data included mean age, gender, location of hematoma, neuroradiologist’s interpretative report of the MRI, and management steps taken in response to the results of the MRI. Logistic regression was used to determine whether the overall yield of MRI in these patients was significant. Results: We found 222 patients with ICH in our database. Forty-eight patients met our inclusion criteria, of which 24 had brain MRI done as a part of their hospital workup. Brain MRI obtained in 2 (8%) of the 24 patients revealed abnormalities that led to a change in management. The diagnostic yield of MRI and the management decisions that followed were both insignificant. Conclusions: The diagnostic yield of brain MRI in patients with nonlobar hypertensive ICH is low and does not result in significant changes in management. PMID:25829985

    A cross-sectional study involving 2502 subjects was conducted to evaluate salt intake, knowledge of salt intake, and blood pressure control in hypertensive patients. The blood pressure control rate was 33.5% among the hypertensive patients. Of the patients, 69.9% had salt intake higher than 6 g/d. Overall 35.0% knew the recommended salt intake, and 94.9% knew that "excess salt intake can result in hypertension." Altogether, 85.8% of patients had received health education related to a low-salt diet at some time. Patients who consumed less than 6 g/d of salt had a higher control rate than those who consumed more than 6 g/d (48.7% vs. 27.0%; χ(2) = 111.0; P < .001). Patients with knowledge of the recommended salt intake had a higher control rate than those without (45.8% vs. 26.9%; χ(2) = 91.3; P < .001). Our findings suggest a high salt intake and low blood pressure control rate among Chinese hypertensive patients. Knowledge of recommended salt intake is inappropriate for patients with education of a low-salt diet.

    There is increasing evidence that patient centered care, including communication skills, is an essential component to chronic illness care. Our aim was to evaluate patient centered primary care as a determinant of medication adherence. We mailed 1,341 veterans with hypertension the Short Form Primary Care Assessment Survey (PCAS) which measures elements of patient centered primary care. We prospectively collected each patient's antihypertensive medication adherence for 6 months. Patients were characterized as adherent if they had medication for >80%. 654 surveys were returned (50.7%); and 499 patients with complete data were analyzed. Antihypertensive adherence increased as scores in patient centered care increased [RR 3.18 (95% CI 1.44, 16.23) bootstrap 5000 resamples] for PCAS score of 4.5 (highest quartile) versus 1.5 (lowest quartile). Future research is needed to determine if improving patient centered care, particularly communication skills, could lead to improvements in health related behaviors such as medication adherence and health outcomes.

    Background Improved outcomes with expanding treatment options for patients with pulmonary arterial hypertension present the opportunity to consider additional end-points in approaching therapy, including factors that influence health-related quality of life. However, comparatively little is known about health-related quality of life and its determinants in patients with pulmonary arterial hypertension. Methods Health-related quality of life was evaluated in a cross sectional study of 155 outpatients with pulmonary arterial hypertension using generic and respiratory-disease specific measurement tools. Most patients had either World Health Organization functional Class II or III symptoms. Demographic, hemodynamic and treatment variables were assessed for association with health-related quality of life scores. Results Patients with pulmonary arterial hypertension suffered severe impairments in both physical and emotional domains of health-related quality of life. Patients with idiopathic ("primary") pulmonary arterial hypertension had the best, and those with systemic sclerosis the worst health-related quality of life. Greater six-minute walk distance correlated with better health-related quality of life scores, as did functional Class II versus Class III symptoms. Hemodynamic measurements, however, did not correlate with health-related quality of life scores. No differences in health-related quality of life were found between patients who were being treated with calcium channel antagonists, bosentan or continuously infused epoprostenol at the time of quality of life assessment. Conclusion Health-related quality of life is severely impaired in patients with pulmonary arterial hypertension and is associated with measures of functional status. Specific associations with impaired health-related quality of life suggest potential areas for targeted intervention. PMID:16092961

    Renal cell carcinoma (RCC) is one of the most common kidney malignancies. An upgraded comprehension of the molecular biology implicated in the development of cancer has stimulated an increase in research and development of innovative antitumor therapies. The aim of the study was to analyze the medical literature for hypertension and renal toxicities as the adverse events of the vascular endothelial growth factor (VEGF) signaling pathway inhibitor (anti-VEGF) therapy. Relevant studies were identified in PubMed and ClinicalTrials.gov databases. Eligible studies were phase III and IV prospective clinical trials, meta-analyses and retrospective studies that had described events of hypertension or nephrotoxicity for patients who received anti-VEGF therapy. A total of 48 studies were included in the systematic review. The incidence of any grade hypertension ranged from 17% to 49.6%. Proteinuria and increased creatinine levels were ascertained in 8% to 73% and 5% to 65.6% of patients, respectively. These adverse events are most often mild in severity but may sometimes lead to treatment discontinuation. Nephrotoxicity and hypertension are related to multiple mechanisms; however, one of the main disturbances in those patients is VEGF inhibition. There is a significant risk of developing hypertension and renal dysfunction among patients receiving anti-VEGF treatment; however, there is also some evidence that these side effects may be used as biomarkers of response to antiangiogenic agents.

    The study was aimed at bettering therapeutic outcomes for patients suffering from adrenal-aetiology arterial hypertension, with the objective deemed attainable at the expense of revealing and removing the underlying causes potentially contributing to unfavourable results obtained after roentgenoendovascular ablation of the adrenal glands. We retrospectively examined the medical records of 49 patients having undergone hospital treatment within the time frame from 1992 to 2007 for recurrent arterial hypertension poorly controlled by previously endured roentgenoendovascular (REV) interventions. The identified causes contributing heavily to poor clinical outcomes obtained after the REV-ablation procedures appeared to have been as follows: renal parenchymatous diseases in 20 patients having a long history of arterial hypertension with evidence ofnephroangiosclerosis; insufficient devitalisation of the adrenal glands in a further 19 patients; a pheochromocytoma of the right adrenal gland in only one instance; and newly onset renovascular hypertension in the remaining nine subjects. It was determined that poor therapeutic outcomes had primarily been caused by overestimating the indications for performing REV ablation of the adrenal glands, being seemingly wanton as a corrective measure to have been taken in the presence of inflammatory diseases of the renal parenchyma and secondary hyperplasia of the adrenal gland, with the second-in-order contributory cause appearing to be insufficient devitalisation of the adrenal glands afflicted by hyperplasia and/or aldosteroma. The development of renal artery stenosis in the remote period after REV interventions may also be responsible for a relapse of arterial hypertension, which is quite often the case.

    To explore the relationship between apolipoprotein E polymorphism and cognitive function in primary hypertension patients, we collected 200 Chinese primary hypertensive patients. Blood pressure (BP), heart rate (HR), height, body weight, waistline, hip circumference were measured. The Mini Mental State Examination (MMSE) was applied to test the cognitive function and compute score. Full-automatic bio-chemistry analyzer was used to determine total cholesterol (TC) and triglyeride (TG) and fasting glucose. The polymerase chain reaction-restriction fragment length polymorphism (PCR-RELP) was used for the analysis of the apolipoprotein E polymorphism. We found that in primary hypertension patients, the genotype frequency of epsilon3/4 and epsilon4/4 were significantly higher in the cognitive impairment group than that in the cognitive normal group. The allele frequency of e4 is obviously higher in the cognitive impairment group than that in the cognitive normal group. Age and epsilon4/4 genetype were positively correlated with hypertensive-cognitive impairment, while cultural level was negtively correlated with it. ApoEepsilon4 allele and age might be risk factors for the cognitive impairment in hypertensive patients. The epsilon4 homozygote (epsilon4/4) might be an important influencing factor for the progression of cognitive impairment.

    Luseogliflozin, a selective sodium glucose cotransporter 2 inhibitor, was demonstrated in a previous 24-week study of type 2 diabetic patients to be efficacious and well tolerated. This study mainly aimed to evaluate the long-term safety of luseogliflozin monotherapy in Japanese type 2 diabetic patients based on the Japanese guidelines. Additionally, long-term efficacy was also evaluated. Patients on diet and exercise therapy alone with an HbA1c of 6.9-10.5% received luseogliflozin 2.5 mg once daily for 52 weeks. For patients with insufficient glycemic control, this dose was able to be increased to 5 mg at Week 24. Adverse events (AEs), clinical laboratory tests, vital signs and 12-lead electrocardiograms were used to assess safety. Efficacy endpoints consisted of changes in HbA1c, fasting plasma glucose (FPG), and body weight from baseline. Of 299 patients who received luseogliflozin, 279 completed the study. Most AEs were mild in severity with incidences of AEs and adverse drug reactions at 75.3% and 16.7%, respectively. Although hypoglycemia was observed in 7 patients (2.3%), no major hypoglycemic episodes occurred. The incidences of AEs of special interest, including pollakiuria, volume depletion and urinary tract/genital infections, were at acceptable levels. Luseogliflozin significantly lowered HbA1c (-0.50%, P< 0.001), FPG (-16.3 mg/dL, P< 0.001) and body weight (-2.68 kg, P< 0.001) at Week 52 compared to baseline. Up-titration to 5 mg further improved glycemic control. In this long-term study of Japanese type 2 diabetic patients, luseogliflozin monotherapy was well tolerated for 52 weeks and provided a sustained glycemic lowering effect and reduced body weight.

    The aim of present study is to compare the efficacy and safety of adding vildagliptin with sulfonylurea dose-increasing as an active comparator in patients who had inadequately controlled type 2 diabetes mellitus (T2DM) using metformin plus sulfonylurea in real clinical practice. Patients using metformin plus sulfonylurea were assigned to either vildagliptin add-on (50 mg twice a day, n=172) or sulfonylurea dose-increasing by 50% (n=172) treatment groups. The primary endpoint was a change in HbA(1c) after 24 weeks. The secondary endpoints were patients achieving HbA(1c)≤7.0% (53 mmol/mol) and changes in the fasting plasma glucose (FPG), 2-h postprandial glucose (2pp), lipid profiles, and urine albumin-to-creatinine ratio. Body weight and hypoglycemia were also investigated. The mean HbA(1c) at baseline was 8.6% (70 mmol/mol) in both groups. At week 24, the adjusted mean HbA(1c) levels decreased by -1.19% (-13.09 mmol/mol) with vildagliptin add-on and -0.46% (-5.06 mmol/mol) with sulfonylurea (P<0.001). Significantly more vildagliptin add-on patients achieved HbA(1c)≤7.0% (53 mmol/mol) than did sulfonylurea patients (40.1% vs. 7.9%; P<0.001). Greater reductions in FPG and 2pp were observed with vildagliptin add-on than with sulfonylurea (P<0.001). The vildagliptin add-on group exhibited no clinically relevant weight gain and had a lower incidence of hypoglycemia compared with the sulfonylurea group. Vildagliptin add-on therapy might be a suitable option for patients with T2DM that is controlled inadequately by metformin and sulfonylurea, based on its greater glucose control and better safety profile (ClinicalTrial.gov: NCT01099137).

    Introduction The objective of this systematic review is to investigate the effectiveness, efficacy and safety of multiple concomitant lifestyle modification therapies for patients with hypertension or prehypertension. Methods and analysis Electronic searches will be performed in the Cochrane Library, OVID, EMBASE, etc, along with manual searches in the reference lists of relevant papers found during electronic search. We will identify eligible randomised controlled trials utilising multiple lifestyle modifications to lower blood pressure. The control could be drug therapy, single lifestyle change or no intervention. Changes in systolic blood pressure and diastolic blood pressure constitute primary end points, and secondary end points include the number of patients meeting the office target blood pressure, the number of patients reporting microvascular or macrovascular complications, etc. We will extract descriptive, methodological and efficacy data from identified randomised controlled trials (RCTs). We will calculate the relative risk for proportion of patients with a normal blood pressure in the experimental group. Dichotomous data will be analysed using risk difference and continuous data using weighted mean differences, both with 95% CI. We will use the χ2 test and the I2 statistic to assess heterogeneity. We will use the fixed effects model to compute the efficacy unless there is evidence of heterogeneity. If heterogeneity of effect size persists with respect to blood pressure change, further metaregression will be performed within groups. We will examine the potential for publication bias by using a funnel plot. Dissemination We will synthesise results from RCTs which provide more precise and accurate information on the effect of multiple lifestyle changes on blood pressure. The results of this review will increase the understanding of multiple lifestyle modifications for patients with hypertension or prehypertension. Trail registration number Our protocol

    BACKGROUND The aim of this study was to investigate the differences in shear wave velocity (SWV) in renal cortex, renal medulla, and renal sinuses between gestational hypertension and normal pregnant women. MATERIAL AND METHODS Ninety patients with gestational hypertension and 30 women with normal pregnancy were enrolled in this study. Kidney biopsy was performed within 6 weeks to 3 months postpartum to determine the pathological nature of renal injury. According to the classification criteria for gestational hypertension, the patients were divided into 3 groups. Gestational hypertension only patients were classified as Group A; patients with mild preeclampsia as group B; patients with severe preeclampsia as group C; normal pregnant women as a control group. Virtual Touch Quantification technique was used to measure renal shear wave velocity; blood pressure, urine analysis, and renal function were also tested. RESULTS There was no difference in renal function between patients in group A and the control group (p>0.05), but there was a significant difference in renal function among patients in group A, B, and C, and there was a significant difference in renal function between patients in group B and C versus control (p<0.05 for all comparisons). There was also a significant difference in SWV values of the renal cortex, renal medulla, and renal sinus between patients in group A, B, and C versus control group (p<0.05). CONCLUSIONS The SWV values of the renal cortex, renal medulla, and renal sinus in patients with gestational hypertension were smaller than those of normal pregnant women, and the more severe the kidney injury, the smaller the SWV value.

    OBJECTIVE To monitor the presence and cleavage of synaptosomal-associated protein of 25 kDa (SNAP-25) by botulinum toxin type A (botox-A), in human detrusor muscle, as the effects of botox-A in the urinary bladder last significantly longer than when applied for disorders of striated muscles. PATIENTS AND METHODS Tissue samples were obtained from eight patients with end-stage neurogenic bladder at different times after injection with botox-A. The resected bladder domes were examined using biochemical and immunohistological techniques. RESULTS The presence of intact SNAP-25 in human bladder was detected, for the first time, in all samples by both Western blotting and immunofluorescence. By contrast, detection of a band potentially representing toxin-cleaved SNAP-25(A) required its enrichment by precipitation with a specific antibody. This putative product was present in four of six patients treated with botox-A 5 weeks to 11 months previously, but could not be detected in one patient 30 months after botox injection, and in an untreated control. Fluorescence microscopy showed no obvious effects of the toxin treatment on the presence and pattern of SNAP-25-positive neurones. CONCLUSIONS A limited amount of SNAP-25 appears to be cleaved in nerves that innervate the smooth detrusor muscle in most patients who had been injected with botox-A; its absolute identification was precluded by the sensitivity of the detection. This protein was detectable much longer after toxin treatment than published for rodent striated muscle, and thus could contribute to the clinically reported longer duration of the effectiveness of botox-A.

    OBJECTIVE: Community health centers (HCs) provide care for millions of medically underserved Americans with disproportionate burdens of hypertension and hyperlipidemia. For both conditions, treatment guidelines recently became more stringent and quality improvement (QI) efforts have intensified. We assessed hypertension and hyperlipidemia management in HCs during this time of guideline revision and increased QI efforts. DESIGN: Cross-sectional chart review. SETTING AND PARTICIPANTS: Eleven Midwestern HCs for 2000 and 9 for 2002 provided audit data from 2,976 randomly chosen patients with hypertension and/or hyperlipidemia. MEASUREMENT: Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure (JNC VI/VII) and National Cholesterol Education Program Adult Treatment Panel (NCEP-ATP III) guidelines were used to assess management of these conditions. RESULTS: Hypertension (2000, N=808; 2002, N=692) and hyperlipidemia (2000, N=774; 2002, N=702) outcomes improved for specific clinical subgroups. Hypertensive patients with 1 or more cardiovascular risk factors demonstrated significant improvement (34% vs. 45% controlled at <140/90 mm Hg, p=0.02). Hypertension control for persons with diabetes, renal failure and heart failure increased (16% vs. 28% controlled at <130/85 mm Hg, p=0.006). LDL control increased significantly for patients with 2 or more risk factors (39% vs. 58% controlled at <130 mg/dl, p=0.008). Other clinical subgroups showed trends toward better control, although there was insufficient power to detect significant differences for these groups. CONCLUSION: Hypertension and hyperlipidemia outcomes improved for some risk groups; however, ongoing QI is necessary.

    Background This meta-analysis was conducted to determine the efficacy, safety and tolerability of tofacitinib in the treatment of rheumatoid arthritis in patients with an inadequate response or intolerance to at least one of the nonbiologic or biologic disease-modifying antirheumatic drugs (DMARDs). Methods Electronic based literature search was conducted in the databases of HINARI (Health InterNetwork Access to Research Initiative), MEDLINE and Cochrane library. The studies included in the meta-analysis were double-blind randomized clinical trials that were conducted in treatment-refractory or intolerant patients with rheumatoid arthritis. The odds ratios (OR), standardized mean differences (SMD) and the 95% confidence intervals (95% CI) were determined by using the random effects model. Heterogeneity among the included studies was evaluated by I2 statistics. Results The odds of tofacitinib treated patients who met the criteria for an at least a 20% improvement in the American College of Rheumatology scale (ACR 20) was more than 4 times higher than placebo treated patients (overall OR = 4.15; 95% CI, 3.23 to 5.32). Even though the discontinuation rate due to adverse events was not different from placebo groups, tofacitinib was associated with infections (overall SMD = 1.96, 95% CI = 1.428 to 2.676), reduction in neutrophil counts (overall SMD = -0.34, 95% CI = -0.450 to -0.223) and elevated levels of LDL cholesterol and liver enzymes. Conclusions Tofacitinib was effective in the treatment of active rheumatoid arthritis in patients with an inadequate response or intolerance to at least one DMARDs. However, treatment with tofacitinib was associated with infections and laboratory abnormalities. PMID:24279308

    Idiopathic pulmonary arterial hypertension (IPAH) is characterized by a progressive increase in pulmonary vascular resistance, which may lead to right ventricular failure and death. Major cardiovascular and pulmonary alterations occur during pregnancy and therefore worsen or increase the complications of pulmonary arterial hypertension (PAH). A patient diagnosed with IPAH after a successful full-term pregnancy and cesarean section with epidural anesthesia is presented. The postoperative course was complicated by progressive dyspnea, and lower limb edema. The outcome of treatment with sildenafil during puerperium was favorable in this patient. The clinical course was complicated by an unexpected spontaneous pregnancy after primary infertility.

    The abnormal metabolism of metal ions plays an important role in health and disease conditions, and studies about them have been attracting significant interest. The aim of our study was to assess the heavy metals (cadmium (Cd), nickel (Ni), lead (Pb), and zinc (Zn)) in scalp hair samples of 50 Irish and 78 Pakistani hypertensive patients of an urban population together with 50 Irish and 96 Pakistani non-hypertensive male subjects in the age group of 30-50 years. The concentrations of trace and toxic elements were measured by inductively coupled plasma-atomic emission spectrophotometer and atomic absorption spectrophotometer before microwave-assisted acid digestion. The validity and accuracy of the methodology were checked using certified reference materials, and by the conventional wet acid digestion method on the same certified reference materials and on real samples. The recovery of all the studied elements was found to be in the range of 97.5-99.7% in certified reference material. The results of this study showed that the mean values of cadmium, nickel, and lead were significantly higher in scalp hair samples of both Pakistani and Irish hypertensive patients than in referents (p < 0.001); whereas, the concentration of zinc was lower in the scalp hair samples of hypertensive patients of both genders. The deficiency of zinc and the high exposure of trace and toxic metals may be the risk factors associated with hypertension.

    Background: Hypertension, an important risk factor for the health of human being, is often accompanied by various comorbidities. However, the incidence patterns of those comorbidities have not been widely studied. Aim: Applying big-data techniques on a large collection of electronic medical records, we investigated sex-specific and age-specific detection rates of some important comorbidities of hypertension, and sketched their relationships to reveal the risk for hypertension patients. Methods: We collected a total of 6,371,963 hypertension-related medical records from 106 hospitals in 72 cities throughout China. Those records were reported to a National Center for Disease Control in China between 2011 and 2013. Based on the comprehensive and geographically distributed data set, we identified the top 20 comorbidities of hypertension, and disclosed the sex-specific and age-specific patterns of those comorbidities. A comorbidities network was constructed based on the frequency of co-occurrence relationships among those comorbidities. Results: The top four comorbidities of hypertension were coronary heart disease, diabetes, hyperlipemia, and arteriosclerosis, whose detection rates were 21.71% (21.49% for men vs 21.95% for women), 16.00% (16.24% vs 15.74%), 13.81% (13.86% vs 13.76%), and 12.66% (12.25% vs 13.08%), respectively. The age-specific detection rates of comorbidities showed five unique patterns and also indicated that nephropathy, uremia, and anemia were significant risks for patients under 39 years of age. On the other hand, coronary heart disease, diabetes, arteriosclerosis, hyperlipemia, and cerebral infarction were more likely to occur in older patients. The comorbidity network that we constructed indicated that the top 20 comorbidities of hypertension had strong co-occurrence correlations. Conclusions: Hypertension patients can be aware of their risks of comorbidities based on our sex-specific results, age-specific patterns, and the comorbidity network

Methods Patients (N = 469) received canagliflozin 100 or 300 mg or placebo once daily during a 26-week core period and a 26-week extension. Prespecified primary end-point was change in HbA1c at 26 weeks. Secondary end-points included change in HbA1c at week 52 as well as proportion of patients achieving HbA1c < 7.0%, change in fasting plasma glucose (FPG) and systolic blood pressure, and per cent change in body weight, high-density lipoprotein cholesterol, and triglycerides (weeks 26 and 52). Results HbA1c was significantly reduced with canagliflozin 100 and 300 mg vs. placebo at week 26 (–0.85%, –1.06%, and –0.13%; p < 0.001); these reductions were maintained at week 52 (–0.74%, –0.96%, and 0.01%). Both canagliflozin doses reduced FPG and body weight vs. placebo at week 26 (p < 0.001) and week 52. Overall adverse event (AE) rates were similar across groups over 52 weeks, with higher rates of genital mycotic infections and osmotic diuresis-related AEs seen with canagliflozin vs. placebo; these led to few discontinuations. Increased incidence of documented, but not severe, hypoglycaemia episodes was seen with canagliflozin vs. placebo. Conclusions Canagliflozin improved glycaemic control, reduced body weight, and was generally well tolerated in T2DM patients on metformin plus sulphonylurea over 52 weeks. PMID:24118688

    Background. The aim of the present study was to determine the prevalence of orthostatic hypertension (OHT) in elderly patients with type 2 diabetes and its relation to metabolic and echocardiographic parameters. Methods. This was an analytical cross-sectional study in 97 patients normotensive or hypertensive. OHT was defined as a ≥10 mmHg increase in systolic blood pressure after four minutes in the standing position. Results. The prevalence of OHT was 20.6%. The mean body mass index was significantly higher in patients with OHT than in those without it (29.80 ± 4.10 versus 27.51 ± 3.98 kg/m2; P = 0.026). There were no statistically significant differences between the two groups for other metabolic parameters. Among the 68 patients who had an echocardiographic examination 27% of those with OHT had an increase in their left atrial volume index (LAVi) compared with 75% of those who did not have OHT (P = 0.004). The mean LAVi of patients with OHT was significantly lower than that of those without OHT (26.27 ± 6.37 versus 32.65 ± 7.54, resp.; P = 0.011). Conclusion. We found a high prevalence of orthostatic hypertension and a lower left atrial volume indexed in the patients with orthostatic hypertension. PMID:26078756

    Objective: This pilot study explored whether learning style–tailored education materials, “information prescriptions,” are effective in increasing hypertension knowledge in emergency room patients. Methods: In a randomized trial, hypertensive emergency medicine patients received either standard care discharge instructions or discharge instructions in combination with an information prescription individualized to each patient's learning-style preference. Two weeks post-visit, the study team assessed changes in hypertension knowledge via a survey. Results: No significant difference was observed for changes in quiz scores on the hypertension knowledge assessment, though patients receiving the tailored information prescriptions reported higher levels of satisfaction with intervention materials. Conclusion: The study demonstrated the workflow feasibility of implementing a learning-style approach to patient education in the emergency department setting. Further research is needed to develop more robust measures of high blood pressure knowledge among the emergency department patient population. This work will contribute to establishing a framework for developing customized information prescriptions that can be broadly adapted for use in varied settings and with varied health care conditions.

    OBJECTIVE--To assess the prevalence of symptomatic and silent myocardial ischaemia in patients with hypertensive left ventricular hypertrophy. DESIGN--Cross sectional study. SETTING--University department of medical cardiology. PATIENTS--90 patients (68 men and 22 women; mean age 57 (range 25 to 79)) with left ventricular hypertrophy due to essential hypertension. INTERVENTIONS--48 hour ambulatory ST segment monitoring (all patients), exercise electrocardiography (n = 79), stress thallium scintigraphy (n = 80), coronary arteriography (n = 35). RESULTS--43 patients had at least one episode of ST segment depression on ambulatory electrocardiographic monitoring. The median number of episodes was 16 (range 1 to 84) with a median duration of 8.6 (range 2 to 17) min. Over 90% of these episodes were clinically silent. 26 patients had positive exercise electrocardiography and 48 patients had reversible thallium perfusion defects despite chest pain during exercise in only five patients. 18 of the 35 patients who had coronary arteriography had important coronary artery disease. Seven of these patients gave no history of chest pain. CONCLUSIONS--Symptomatic and silent myocardial ischaemia are common in hypertensive patients with left ventricular hypertrophy, even in the absence of epicardial coronary artery disease.

    Elevated homocysteine (HCY) and smoking are both important risk factors for hypertensive patients. However, whether they have crossing effect on renal function deterioration of hypertensive patients and what is the underlying mechanism are unclear. In the present study, 3033 participants diagnosed as essential hypertension with estimated glomerular filtration rate (eGFR)> 30 ml/min/1.73 m2 from southern China were enrolled in this cross-sectional study. We collected the demographic and clinical data. In addition, the mediation effects were analyzed. The results showed that, comparing with non-smokers, smokers had significant higher levels of HCY (13.10 (11.20−16.87) vs. 11.00 (8.90−13.40) umol/L, P < 0.001) and lower eGFR (79.71 (66.83−91.05) vs. 82.89 (69.80−95.85) ml/min/1.73m2, P < 0.001). HCY levels and smoking were independently associated with decreased eGFR. Meanwhile, eGFR levels were significantly negatively correlated with HCY (P < 0.001), and this correlation might be stronger in current smokers. Current smoker consuming over 20 cigarettes per day would accelerate early renal function deterioration (OR = 1.859, P = 0.019). The mediation effects analysis further showed that the association between smoking and renal function deterioration was mediated by HCY. And elevated HCY was accounted for 56.94% of the estimated causal effect of smoking on renal function deterioration in hypertensive patients. Our findings indicated that cigarette smoking was associated with renal function deterioration in hypertensive patients, and the association between cigarette smoking and renal function deterioration was probably mediated by elevated HCY. Therefore, HCY-lowering therapy may be beneficial for renal function deterioration in hypertensive smoking patients. PMID:27852066

    In this study, our aim was to assess the coronary flow reserve (CFR) by performing the adenosine stress (99m)Tc-MIBI single-photon computed tomographic (SPECT) myocardial perfusion imaging in patients with hypertension. 47 hypertensive patients with normal coronary angiography were divided into 2 groups, defined by the presence (LVH, n = 22) and absence (non-LVH, n = 25) of left ventricular hypertrophy with 17 normal cases as controls. All patients were administered the adenosine stress-rest (99m)Tc-MIBI scintigraphy. 0.14 mg/kg/min adenosine was administered by continuous infusion for 6 min. We found that adenosine-induced myocardial ischemia was present in 26 cases (55.3 %) with 87 segments (20.6 %) showing abnormal distribution in the hypertensive group versus a single case (5.9 %) (χ (2) = 31.12, P < 0.001) and segment (0.7 %) (χ (2) = 32.90, P < 0.001) in the control group by SPECT perfusion. In the LVH group, 17 cases (77.3 %) and 67 segments (33.8 %) of myocardial ischemia were present. In the non-LVH group, there were 9 cases (36.0 %) (χ (2) = 8.06, P < 0.001), 20 segments (8.9 %) (χ (2) = 40.13, P < 0.001). There was a significant decrease in coronary reserve in the hypertensive groups following adenosine infusion with a fourfold decrease in cases and a sixfold decrease in segments (P < 0.001). Our study suggests that assessing CFR by the (99m)Tc-MIBI adenosine stress by SPECT imaging is a relatively easy, safe, and non-invasive test in patients with hypertension. We noted a decrease in CFR in patients with hypertension. This decrease was especially remarkable for hypertensive patients with LVH. This study shows that administering the (99m)Tc-MIBI adenosine stress by SPECT imaging is a safe, simple, and non-invasive test for detecting CFR in patients with hypertension.

    We conducted this systematic reviews and meta-analysis to investigate the safety and efficacy of ocrelizumab in patients with active rheumatoid arthritis (RA) who exhibited resistance or intolerance to methotrexate or biological therapy. We performed a web-based literature search of PubMed, Google Scholar, EBSCO, Scopus, Embase, and Web of science for studies that compared ocrelizumab plus methotrexate versus methotrexate plus placebo in RA patients. Data were extracted from eligible studies and pooled as risk ratios (RR), using RevMan software. Pooling data from four RCTs (2230 patients) showed that ocrelizumab plus methotrexate were superior to methotrexate plus placebo at 24 weeks in terms of improvement on the American college of rheumatology (ACR20, ACR50, and ACR70) criteria (p < 0.00001), disease activity score 28-ESR (RR = 3.77, 95% CI [2.47, 5.74], p < 0.00001), and Sharp/van der Heijde radiological score (RR = 1.63, 95% CI [1.43, 1.85], p < 0.00001). These effects were consistent among all ocrelizumab doses. The rates of serious adverse events were comparable between the ocrelizumab and placebo containing groups (RR = 1, 95% CI [0.78, 1.28], p = 0.98). However, infusion related reactions were significantly higher in ocrelizumab group (RR = 2.13, 95% CI [1.69, 2.68], p < 0.00001), compared to placebo group. The combination of ocrelizumab plus methotrexate was superior to methotrexate plus placebo on all clinical and radiographic improvement scales. The incidence of adverse events, including serious adverse events, was comparable between both groups. Future trials should investigate the efficacy of ocrelizumab alone and develop strategies to alleviate its related infusion reactions.

    There is some question about the relationship between hereditary spherocytosis (HS) and pulmonary arterial hypertension, even associated with splenectomy. The finding of BMPR2 mutations in our patient suggests that other factors are necessary for the development of the disease, and perhaps, the incidence of pulmonary hypertension is not increased in patients with HS.

    According to the Canadian Hypertension Society (Canadian Hypertension Education Program, 2008), hypertension remains a significant health problem that is projected to become a greater global burden in the next 20 years. Internationally, the estimated total number of adults with hypertension in 2000 was 972 million; 333 million in economically developed countries. Current trends suggest that the number of adults with hypertension will increase by about 60% to a total of 1.56 billion by 2025. Despite the availability of effective treatment, more than half of patients treated for hypertension drop out of care entirely within a year of diagnosis. Fifty per cent of patients who remain under medical supervision take only 80% of their prescribed medications. As a result, 75% of patients with a diagnosis of hypertension do not achieve optimum blood pressure control due to poor adherence to anti-hypertensive treatment. Nurses represent a formidable force in improving adherence and care outcomes by understanding the dynamics of compliance, and employing techniques in assessing and monitoring the problems of nonadherence. Nurses are well positioned to effectively use sustained strategies to improve adherence, thereby decreasing the global burden of hypertension. Using a case study approach, this author explores the dynamics of adherence and reviews techniques for assessing, monitoring, and improving compliance in hypertension therapy.

    The effect of exercise of gradually increased intensity, i.e. 75 W for 20 min followed by 100 W for 20 min, on plasma renin concentration (PRC) and plasma aldosterone concentration (PAC) was studied in young patients with essential hypertension and normotensive control subjects. During exercise without previous sodium loading PRC and PAC increased to the same degree in both hypertensives and normotensives during light exercise; PRC increased further significantly in the normotensives (63 to 72 microIU/ml (medians), P less than 0.01) but not in the hypertensives (46 to 51 microIU/ml) during heavy exercise. PRC and PAC were significantly correlated during both 75 W (rho = 0.633, P less than 0.05) and 100 W (rho = 0.635, P less than 0.05) exercise in the normotensives, but not in the hypertensives. During exercise after loading with 500 ml sodium chloride (0.85 mol/l) PRC and PAC increased in both hypertensives (28 to 42 microIU/ml, P less than 0.01; 0.11 to 0.53 nmol/l, P less than 0.01) and normotensives (22 to 33 microIU/ml, P less than 0.02; 0.12 to 0.34 nmol/l, P less than 0.01), although to a considerably lower degree than without previous loading. PRC and PAC were, however, significantly higher in the hypertensive than in the normotensive group after exercise. It is suggested that the responsiveness of the renin-aldosterone system is abnormal during exercise in young patients with mild essential hypertension, both without and with previous intravenous sodium loading.

    Little is known about the relationship between the circadian BP rhythm and endothelial function in patients with essential hypertension. Consequently, we have hypothesized, that hypertensive patients with non-dipper circadian BP profile have more deteriorated endothelial function, than those with dipper BP profile. 57 untreated hypertensive patients and 17 normotensive controls were undergone to the anthropometrical measurements, physical examinations, review of their medical histories, 24-hour ABPM and vascular doppler-echography with high resolution ultrasound. Circadian BP profile was not independent from the BP level; namely, dipper profile was more frequent in normotensives. Independent from hypertension, dipper patients had significantly higher FMD%. In the whole study population, FMD showed strong negative correlation with 24-hour SBP, DBP and PP. Our study confirms the presence of disturbed endothelium-dependent vasodilatation in AH. Furthermore, our study showed that non-dipper circadian BP rhythm is associated with the significant impairment of endothelial function. Consequently, we can suggest that patients with non-dipper circadian BP profile could be assessed as a high risk group, which might need permanent supervising for avoiding of future cardiovascular and cerebrovascular complications.

    Background Psoriasis vulgaris is one of the most prevalent chronic, inflammatory skin disorders. Patients with psoriasis have excess risk of essential hypertension. Masked hypertension (MH), defined as normal office blood pressure (BP) with elevated ambulatory BP (ABPM), has been drawing attention recently due to its association with increased risk of developing sustained hypertension, cardiovascular morbidity, and mortality. The aim of this study was to investigate the prevalence of MH in psoriatic patients. Material/Methods On hundred and ten middle-aged, normotensive, non-obese patients with psoriasis vulgaris and 110 age- and sex-matched normotensive controls were included in the study. ABPM was performed in all participants over a 24-h period. The clinical severity of the disease was determined according to current indexes. Results The prevalence of MH among subjects with psoriasis vulgaris was 31.8% and increased compared to control subjects (p<0.01). Predictors of MH in patients with psoriasis vulgaris were detected as male sex, smoking, obesity-related anthropometric measures, and disease activity. Male sex, waist circumference, and diffuse psoriatic involvement were detected as independent predictors of MH. Conclusions MH is prevalent in patients with psoriasis vulgaris. Assessment with ABPM and close follow-up for development of hypertension is reasonable. PMID:23800996

    Endothelial dysfunction is a common feature in type-2 diabetic patients and in hypertension, and is associated with inflammation, increased levels of circulating soluble adhesion molecules, and atherosclerosis. The aim of this study was to evaluate the relationship between the levels of circulating soluble adhesion molecules and the degree of atherosclerosis in hypertensive type-2 diabetic patients. We studied 30 hypertensive type-2 diabetic patients in whom VCAM-1, ICAM-1, and E-selectin were measured by ELISA. Additionally, the intimal-medial thickness of both the common and internal carotid arteries was measured (B-mode ultrasound). The levels of circulating adhesion molecules and maximal carotid artery intimal-medial thicknesses were correlated using the Spearman correlation coefficient test. Statistical analysis was performed with ANOVA. We found significant correlations between ICAM-1 (r = 0.5) levels and maximal carotid artery intimal-medial thickness these patients. No correlation was observed with E-selectin and VCAM-1. Our results suggest that ICAM-1 is associated and correlated with the degree of atherosclerosis in type-2 diabetic hypertensive patients.

    There is increasing interest in the role of aldosterone in the pathophysiology of hypertension, cardiovascular disease and deteriorating renal function. The aim of this study was to investigate the relationship between aldosterone and the glomerular filtration rate (GFR) in hypertensive patients with preserved renal function. The study involved 186 consecutive hypertensive patients with a GFR >60 mL/min. The GFR was determined using the Modification of Diet in Renal Disease (MDRD) equation and the patients' plasma aldosterone levels were measured. Patients with a GFR between 60-89 mL/min had a significantly higher plasma aldosterone level than those with a GFR >90 mL/min (20.02 ng/dL vs. 15.3 ng/dL; P< .05). Multivariate analysis showed that the plasma aldosterone level was independently associated with the GFR (B=-7.36; P< .001). In hypertensive patients with preserved kidney function, the plasma aldosterone level was observed to increase as the GFR decreased.

    This open-label, blinded study was performed to evaluate the efficacy and tolerability of barnidipine at a titrated dose of 10-15 mg once daily for 8 weeks in the treatment of essential hypertension in 40 Thai patients. 'Office' blood pressure (BP) and 24-h ambulatory BP measurements were recorded. A systolic BP/diastolic BP (SBP/DBP) reduction of 18.0 +/- 13.6/9.1 +/- 6.6 mmHg was obtained. The full response rate among patients with systolic and diastolic hypertension was 63% using either SBP or DBP criteria, and 54% using both SBP and DBP criteria. One of the two patients with isolated systolic hypertension had a full response, and the BP in two of the three patients with isolated diastolic hypertension was normalized. The trough-to-peak ratio and smoothness index for SBP/DBP were acceptable (0.76 +/- 0.63/0.55 +/- 0.26 and 1.2 +/- 0.4/1.2 +/- 0.3, respectively). In conclusion, once-daily barnidipine monotherapy provides effective 24-h BP control and is generally well tolerated in ambulatory patients.

    Objective The purpose of this study was to investigate the relationship between knowledge on arterial hypertension (AH) and its management, and adherence to pharmaceutical treatment. Methods The study included 233 patients diagnosed with AH and treated with hypotensive drugs for at least 1 year. The 8-item © Morisky Medication Adherence Scale (MMAS-8) and the Hypertension Knowledge-Level Scale (HK-LS) were used. Results Sixty-three percent of the patients had a low level of knowledge on AH, with the smallest proportion of correct answers provided for items related to non-pharmaceutical treatment, diet, hypertension definition, and drug adherence. When compared to patients with a high level of knowledge, those with a low knowledge had lower scores in the MMAS (6.45±1.45 vs 7.08±1.04; P=0.038). Multiple-factor analysis showed that statistically significant independent determinants of good adherence included a high level of knowledge (β=0.208; P=0.001), non-pharmaceutical treatment (β=0.182; P=0.006), and frequent blood pressure measurements (β=0.183; P=0.004). The most significant factor in MMAS was knowledge in the “drug adherence” domain (ρ=0.303; P<0.001). Conclusion Patients’ knowledge on hypertension is a significant independent determinant of good adherence. Other independent determinants include non-pharmaceutical treatment and regular blood pressure measurements. Implication for practice The identification of knowledge deficits as a factor contributing to lack of adherence and poor hypertension control remains a key challenge for multidisciplinary team caring for patients with hypertension.

  6. Redefining beta-blocker use in hypertension: selecting the right beta-blocker and the right patient.

    PubMed

    Mann, Samuel J

    2017-01-01

    Randomized controlled trials have concluded that the cardiovascular outcome of first-step treatment of hypertension with traditional vasoconstricting beta-blockers is inferior to treatment with other antihypertensive drug classes. Beta-blocker use is also associated with undesirable side effects. Consequently, some recent guidelines consider beta-blockers an inferior option for first-step treatment of hypertension. Despite this, beta-blockers are still widely prescribed, and likely overused, in the management of hypertension. It is the contention of this perspective that beta-blockers do have an important role in treating hypertension, but their use needs to be much better targeted, by better identification of both the right patient and the right beta-blocker. Identifying the right patient involves consideration of underlying mechanisms of hypertension. In the absence of comorbidities for which a beta-blocker is indicated, beta-blockers would not seem to be the preferred treatment for patients with either sodium/volume-mediated hypertension, for which they are usually ineffective, or for those with renin-angiotensin system-mediated hypertension, for which angiotensin-converting enzyme inhibitors and angiotensin receptor blockers provide equal antihypertensive efficacy with evidence of better outcome and fewer adverse effects. Beta-blockers would instead appear to be best suited for patients with sympathetically driven, that is, neurogenic, hypertension, whether as a first-step drug, such as in patients with hypertension in the acute post-stroke period, in so-called "hyperkinetic" patients, and in patients with labile hypertension, or as an add-on drug in patients with resistant hypertension. In choosing among the beta-blockers, combined alpha/beta-blockade offers advantages over beta-blocker monotherapy and merits greater clinical and research attention. Finally, unreliable bioavailability greatly interferes with the effectiveness of lipophilic, but not

    Lack of nighttime blood pressure (BP) reduction by 10-20% from the mean daytime values (dipping) has been described as a distinguishing feature of essential hypertension and associated, also in normotensive subjects, with increased cardiovascular (CV) risk. Mechanisms involved in the loss of the nocturnal dip are still unclear, but involvement of autonomic nervous system (ANS) activity probably plays a crucial role. Sleep is fundamental in modulating ANS activity to maintain the physiological BP circadian rhythm, and for this reason its integrity has been widely investigated in hypertension. We investigated, under controlled conditions, the autonomic control of the CV system through an autonomic reflex screen in the awake condition and by assessment of circadian rhythm-, day-night-, time-, and state-dependent changes of BP and heart rate (HR) and associated sleep parameters in patients with a recent (≤1 yr) diagnosis of essential grade I hypertension naïve of therapy. Fourteen hypertensive patients (6 males, age: 43 ± 11 yrs; body mass index [BMI]: 24 ± 3 kg/m(2)) were compared with 28 healthy controls matched for sex, age, BMI (2 controls/patient) for cardiovascular reflex and to 8 different subjects from previous controls (6 males), comparable for age and BMI, for the day-night and nighttime CV profiles during two consecutive nights. The cardiovascular reflex screen data showed increased sympathetic effect in hypertensive patients, represented by higher overshoot of BP after Valsalva maneuver. Nighttime sleep architecture during the dark period in terms of duration, representation of sleep stages, sleep fragmentation, and incidence of arousals-periodic limb movements in sleep (PLMS) and PLMS arousals-was similar in patients and controls. Hypertensive patients displayed higher 24-h BP and HR values, but their sleep-related BP decrease was significantly reduced compared with controls. The circadian rhythms of BP and HR were intact and similar in

    Background. Increased pulmonary vascular resistance in patients with pulmonary hypertension (PH) leads to an increased afterload of right heart and cardiac remodeling which could provide the substrate or trigger for arrhythmias. Supraventricular arrhythmias were associated with clinical deterioration but were not associated with sudden cardiac death (SCD). SCD has been reported to account for approximately 30% of deaths in patients with pulmonary arterial hypertension (PAH). Objective. The role of nonsustained ventricular tachycardia (nsVT) and its prognostic relevance in patients with PH remains unclear. This study evaluated the prognostic relevance of nsVT in patients with PAH and chronic thromboembolic pulmonary hypertension (CTEPH). Methods. Retrospectively, patients with PAH and CTEPH who underwent Holter ECG monitoring and available data of survival were investigated. Results. Seventy-eight (PAH: 55, CTEPH: 23) patients were evaluated. Holter ECG revealed nsVT in 12 patients. Twenty-one patients died during follow-up. In patients with nsVT, tricuspid annular plane systolic excursion was lower (p = 0.001), and systolic pulmonary arterial pressure was higher (p = 0.163). Mean survival of patients without/with nsVT was 155.2 ± 8.5/146.4 ± 21.4 months (p = 0.690). The association between arrhythmias and survival was not confounded by age (p = 0.681), gender (p = 0.752), 6-MW distance (p = 0.196), or arterial hypertension (p = 0.238). Conclusions. In patients with PH, nsVT occurs more often than previously reported, and patients with PH group 1 seem to be more at risk. PMID:28090536

    Several calculation modalities are used today for cardiovascular risk assessment. Cardiovascular risk assessment should be performed in all hypertensive patients. Risk assessment methods being based on the population in which the patient lives and the inclusion of factors such as ethnicity variations, socioeconomic status, and medication use will contribute to improvements in risk assessments. The results should be shared with the patient, and modifiable risk factors must be effectively treated.

    AIMS: The main objective of this study is to describe patients' clinical characteristics and physiological and hemodynamic parameters at the time of diagnosis in a pulmonary hypertension center in Saudi Arabia. MATERIALS AND METHODS: This study reports the results from a single pulmonary hypertension specialized center in Riyadh, Saudi Arabia, namely Prince Sultan Medical Military City/Cardiac Center (PSMMC & CC). Both newly diagnosed (incidence) and referred (prevalence) cases of pulmonary arterial hypertension are included. All characteristics, including clinical, physiological, and hemodynamic parameters at the time of diagnosis are described. RESULTS: A total of 107 patients were identified as having pulmonary arterial hypertension as diagnosed by right heart catheterization. The mean age at diagnosis was 36 (± 9) years, and there was a female preponderance of 62.6%. The mean duration between symptom onset and diagnosis was 27.8 (± 9.0) months. At the time of enrollment, 56.1% of patients were in functional class III and 16.8% were in functional class IV. Fifty five patients (51.4%) were diagnosed as idiopathic pulmonary arterial hypertension, 29 patients (27.1%) as congenital heart disease associated with pulmonary arterial hypertension, 16 patients (15.0%) as connective tissue diseases associated with pulmonary arterial hypertension, 4 patients (3.7%) as heritable pulmonary arterial hypertension, and 3 patients (2.8%) as portopulmonary hypertension. CONCLUSION: This data highlights the current situation of pulmonary arterial hypertension in Saudi Arabia. Our patients are much younger than patients described in other international registries but still detected as late in the course of the disease. A majority of patients displays severe functional and hemodynamic compromise. PMID:25276239

    Introduction: On November 8, 2013, Super Typhoon Haiyan struck the Philippines, causing a humanitarian emergency. According to the World Health Organization, non-communicable diseases (NCDs), also known as chronic diseases, are the leading cause of death and disability around the world. NCDs kill 38 million people each year.  Sixteen million NCD deaths occur before the age of 70; 82% of which occurred in low- and middle-income countries.  NCDs are further exacerbated during a crisis, and addressing them should be a concern of any medical disaster response. Methods: We conducted a retrospective observational study to determine the prevalence of hypertension among patients seeking medical care at mobile medical clinics after Typhoon Haiyan in the Philippines. Results: A total of 3,730 adults were evaluated at the mobile medical clinics. Analysis of the medical records revealed that the overall prevalence of hypertension among adult patients was 47%. Approximately 24% of adult females and 27% of adult males were classified with stage 2 Hypertension. Conclusions: Evidence-based guidelines on the management of hypertension and other NCDs (diabetes mellitus, cardiovascular disease, chronic lung disease and mental health) during humanitarian emergencies are limited. Clinical care of victims of humanitarian emergencies suffering with NCDs should be a critical part of disaster relief and recovery efforts.  We therefore recommend the development of best practices and evidence based management guidelines of hypertension and other NCDs in post-disaster settings.

    Essential hypertension is associated with changes in central catecholaminergic pathways which might also be reflected in the pituitary response to stress stimuli. The aim of this study was to determine whether the response of pituitary hormones, cortisol, plasma renin activity, aldosterone and catecholamines to insulin-induced hypoglycaemia is changed in hypertension. We studied 22 young lean male patients with newly diagnosed untreated essential hypertension and 19 healthy normotensive, age- and body mass index (BMI)-matched controls. All subjects underwent an insulin tolerance test (0.1 IU insulin/kg body weight intravenously) with blood sampling before and 15, 30, 45, 60 and 90 min after insulin administration. Increased baseline levels of norepinephrine (P<0.05), increased response of norepinephrine (P<0.001) and decreased response of growth hormone (P<0.001), prolactin (P<0.001), adrenocorticotropic hormone (P<0.05) and cortisol (P<0.001) were found in hypertensive patients when compared to normotensive controls. Increased norepinephrine levels and a decreased pituitary response to metabolic stress stimuli may represent another manifestation of chronically increased sympathetic tone in early hypertension.

    The long-term effects of indapamide or hydrochlorothiazide on blood pressure and renal function were examined in patients with impaired renal function and moderate hypertension. Both drugs controlled hypertension and blood pressure remained normal during the 2 years of the study. Despite this comparable control of hypertension, indapamide therapy was associated with a 28.5 +/- 4.4% increase in creatinine clearance while treatment with hydrochlorothiazide was associated with a 17.4 +/- 3.0% decrease in creatinine clearance. The results of the study indicate that indapamide is superior to hydrochlorothiazide in the treatment of patients with impaired renal function and moderate hypertension.

  15. Does inadequate sleep play a role in vulnerability to obesity?

    2011-01-01

    The prevalence of obesity is increasing rapidly worldwide, which is cause for concern because obesity increases the risk of cardiovascular disease and diabetes, reduces life expectancy and impairs quality of life. A better understanding of the risk factors for obesity is therefore a critical global health concern and human biologists can play an important role in identifying these risk factors in various populations. The objective of this review is to present the evidence that inadequate sleep may be a novel risk factor associated with increased vulnerability to obesity and associated cardiometabolic disease. Experimental studies have found that short-term sleep restriction is associated with impaired glucose metabolism, dysregulation of appetite and increased blood pressure. Observational studies have observed cross-sectional associations between short sleep duration (generally <6 hours per night) and increased body mass index or obesity, prevalent diabetes and prevalent hypertension. Some studies also reported an association between self-reported long sleep duration (generally >8 hours per night) and cardiometabolic disease. A few prospective studies have found a significant increased risk of weight gain, incident diabetes and incident hypertension associated with inadequate sleep. Given the potential link between inadequate sleep and obesity, a critical next step is to identify the social, cultural and environmental determinants of sleep, which would help to identify vulnerable populations. Future human biology research should consider variation in sleep characteristics among different populations and determine whether the associations between sleep and obesity observed in Western populations persist elsewhere.

    The prohypertensive effect of non-steroidal anti-inflammatory drugs (NSAIDs) can be manifested by the decreased efficiency of antihypertensive therapy. The tactics of their differential use in relation to the its effect on blood pressure (BP) in patients with osteoarthrosis (OA) and arterial hypertension (AH) has not been developed for the most effective and safe therapy. In this connection, it is extremely urgent to study the comparative safety of used NSAIDs as to their prohypertensive effect and to work out the management of patients with AH and OA. Ninety-eight patients with second-third degree OA of the knee and hip joints concurrent with the pain syndrome and first-second grade AH were followed up. Diclofenac, ketoprofen, arthrotec, nimesulide, and meloxicam were used. In a control group, the analgesic tramadol was supplemented to the therapy. AH was controlled by enalapril monotherapy. In groups of patients receiving diclofenac, arthrotec, meloxicam, and ketoprofen, there was a trend for the number of cases of an adequate nocturnal BP lowering (Dipper) to reduce and for those of an inadequate nocturnal BP decrease (Non-dipper), which may be accounted for by the prohypertensive effect of these drugs; this trend was most pronounced in the diclofenac and arthrotec groups. Despite its marked prohypertensive effect, nimesulide did not impair circadian BP variations. The central-acting analgesic tramadol exerted no prohypertensive effect and it did not increase BP values. The prohypertensive effect of the tested NSAIDs and tramadol increases in the following order: tramadol, ketoprofen, meloxicam, nimesulide, arthrotec, diclofenac.

    Background Hypertension affects about 80% of people older than 80 years; however, diagnosis and treatment are difficult because about 55% of them do not adhere to treatment recommendations due to low socioeconomic status, comorbidities, age, physical limitations, and frailty syndrome. Aims The purposes of this study were to evaluate the influence of frailty on medication adherence among elderly hypertensive patients and to assess whether other factors influence adherence in this group of patients. Methods and results The study included 296 patients (mean age 68.8±8.0) divided into frail (n=198) and non-frail (n=98) groups. The Polish versions of the Tilburg Frailty Indicator (TFI) for frailty assessment and 8-item Morisky Medication Adherence Scale for adherence assessment were used. The frail patients had lower medication adherence in comparison to the non-frail subjects (6.60±1.89 vs 7.11±1.42; P=0.028). Spearman’s rank correlation coefficients showed that significant determinants with negative influence on the level of adherence were physical (rho =−0.117), psychological (rho =−0.183), and social domain (rho =−0.163) of TFI as well as the total score of the questionnaire (rho =−0.183). However, multiple regression analysis revealed that only knowledge about complications of untreated hypertension (β=0.395) and satisfaction with the home environment (β=0.897) were found to be independent stimulants of adherence level. Conclusion Frailty is highly prevalent among elderly hypertensive patients. Higher level of frailty among elderly patients can be considered as a determinant of lower adherence. However, social support and knowledge about complications of untreated hypertension are the most important independent determinants of adherence to pharmacological treatment. PMID:27994444

    Ambulatory arterial stiffness index (AASI) is a parameter obtained from ambulatory blood pressure monitoring (ABPM) that correlates with clinical endpoints. The aim of this study was to compare AASI in nondiabetic hypertensive patients with and without chronic kidney disease (CKD). Subjects with systemic arterial hypertension (SAH, n = 30) with normal renal function, aged 40 to 75 years, were compared to hypertensive patients with CKD (n = 30) presenting estimated glomerular filtration rate (eGFR) <60 mL/min by MDRD formula. ABPM was carried out in all patients. In CKD group, eGFR was 35.3 ± 2.8 ml/min. The mean 24-hour systolic and diastolic blood pressure (BP) was similar in both groups. AASI was significantly higher in CKD group (0.45 ± 0.03 versus 0.37 ± 0.02, P < 0.05), positively correlated to age (r = 0.38, P < 0.01) and pulse pressure (r = 0.43, P < 0.01) and negatively correlated to nocturnal BP fall (r = -0.28, P = 0.03). These findings indicate the presence of stiffer vessels in CKD hypertensive patients. PMID:22675608

    Background Many epidemiological studies have established the relationship between hypertension and dyslipidemia. Calcium channel blockers (CCBs) are one of the first-line drugs for newly diagnosed patients with essential hypertension. Cilnidipine as a newer CCB acting by blocking both L- and N-type calcium channels possesses additional beneficial effects apart from lowering blood pressure (BP). The aim of this study was to evaluate the effectiveness of cilnidipine in patients with essential hypertension with borderline dyslipidemia and its effects on lipid profile. Methods Out of 45 enrolled patients, who fulfilled the inclusion criteria, only 37 completed the study. Cilnidipine was started at 10 mg/day, and then adjusted to 5 - 20 mg/day to achieve the target blood pressure. Results After 12 weeks of study, patients showed significant reduction in systolic blood pressure, diastolic blood pressure, mean BP, heart rate and serum triglyceride level from baseline values (P < 0.00). Conclusion In clinical setting where both hypertension and hypertriglyceridemia exist, cilnidipine can be a promising drug of choice. PMID:28197288

    Background The relation between hypertension and hyperuricemia has been established by epidemiological studies. Calcium channel blockers are one of the first-line drugs for newly diagnosed patients with essential hypertension. Cilnidipine is a new calcium channel blocker acting by blocking both L- and N-type calcium channels. The aim of this study was to compare the effectiveness of amlodipine and cilnidipine in patients with essential hypertension and their effects on heart rate and serum uric acid levels. Methods Out of 100 enrolled patients, 92 completed the study. They were randomly assigned to amlodipine (N = 47) and cilnidipine (N = 45) groups. Cilnidipine was started at 10 mg/day and then adjusted to 5 - 20 mg/day, and amlodipine was started at 5 mg/day and then adjusted to 2.5 - 10 mg/day. Results After 24 weeks of study, patients in cilnidipine groups showed significant reduction in heart rate and serum uric acid levels from baseline (P = 0.00). Conclusion In clinical setting where both hypertension and hyperuricemia exist, cilnidipine can be a promising drug of choice. PMID:28197287

    The reason why hyperinsulinemia is associated with essential hypertension is not known. To test the hypothesis of a pathophysiologic link mediated by the sympathetic nervous system, we measured the changes in forearm norepinephrine release, by using the forearm perfusion technique in conjunction with the infusion of tritiated NE, in patients with essential hypertension and in normal subjects receiving insulin intravenously (1 mU/kg per min) while maintaining euglycemia. Hyperinsulinemia (50-60 microU/ml in the deep forearm vein) evoked a significant increase in forearm NE release in both groups of subjects. However, the response of hypertensives was threefold greater compared to that of normotensives (2.28 +/- 45 ng.liter-1.min-1 in hypertensives and 0.80 +/- 0.27 ng.liter-1 in normals; P less than 0.01). Forearm glucose uptake rose to 5.1 +/- .7 mg.liter-1.min-1 in response to insulin in hypertensives and to 7.9 +/- 1.3 mg.liter-1.min-1 in normotensives (P less than 0.05). To clarify whether insulin action was due to a direct effect on muscle NE metabolism, in another set of experiments insulin was infused locally into the brachial artery to expose only the forearm tissues to the same insulin levels as in the systemic studies. During local hyperinsulinemia, forearm NE release remained virtually unchanged both in hypertensive and in normal subjects. Furthermore, forearm glucose disposal was activated to a similar extent in both groups (5.0 +/- 0.6 and 5.2 +/- 1.1 mg.liter-1.min-1 in hypertensives and in normals, respectively). These data demonstrate that: (a) insulin evokes an abnormal muscle sympathetic overactivity in essential hypertension which is mediated by mechanisms involving the central nervous system; and (b) insulin resistance associated with hypertension is demonstrable in the skeletal muscle tissue only with systemic insulin administration which produces muscle sympathetic overactivity. The data fit the hypothesis that the sympathetic system mediates

    Gallbladder varices have been reported in patients with portal hypertension. The exact frequency and significance of these collaterals in patients with cirrhotic and noncirrhotic portal hypertension is not known. One hundred and two patients with portal hypertension [38 with cirrhosis, 29 with noncirrhotic portal fibrosis (NCPF) and 35 with extrahepatic portal vein obstruction (EHPVO)] and 25 healthy controls were studied. Gallbladder varices were seen at ultrasound as tortuous, dilated vessels in the wall or in the bed of the gallbladder. In 35 patients (19 patients with and 16 without gallbladder varices) and in 10 healthy controls, gallbladder functions were studied by determining fasting volume (FV) and then residual volume (RV) every 10 min over 1 h after giving a liquid meal of 420 k.cal. Ejection fraction (EF) was computed as a percentage by the formula: FV--RV/FV x 100. Twenty four (24%) patients had gallbladder varices: Five (13%) with cirrhosis, seven (24%) with NCPF, and 12 (34%) with EHPVO. FV in EHPVO patients was seen significantly more than in cirrhotics (31.6 +/- 15.4 vs 19.3 +/- 6.0 ml, p < 0.05). The RV and EF were not different in the three groups of patients compared with the controls. The EF was similar in patients with or without gallbladder varices (63.3 +/- 10.2% vs 64.6 +/- 10.4%). Gallbladder varices are often seen in portal hypertension, more often in EHPVO patients, and these collaterals cause some gallbladder stasis but do not impede gallbladder function and hence seem unlikely to contribute to gallstone formation.

    Despite important advances in its therapeutic management, pulmonary arterial hypertension (PAH) remains an incurable disease. Although numerous drugs exhibited beneficial effects in preclinical settings, only few have reached clinical trial phases, highlighting the challenges of translating preclinical investigations into clinical trials. Potential reasons for delayed PAH drug development may include the inherent limitations of the currently available animal and in vitro models, potential lack of appropriate standardization of the experimental design, regulatory agencies requirements, competing clinical trials and insufficient funding. Although this is not unique to PAH, there is urgency for reducing the number of false positive signals in preclinical studies and optimizing the development of innovative therapeutic targets through performance of clinical trials based on more robust experimental data. The current review discusses the challenges and opportunities in preclinical research to foster drug development in PAH.

    Chest pain is a frequent symptom in patients with pulmonary hypertension of any etiology. Its pathophysiology has not been clearly established, the proposed causes are ischemia due to increased right ventricle wall stress, transient increased pulmonary hypertension resulting in acute pulmonary artery dilatation and external compression of the left main coronary artery (LMCA) by a dilated pulmonary artery. We report and discuss here three cases where the association between chest pain and compression of the LMCA by a dilated pulmonary artery could be shown, and they were treated with coronary stenting.

    Pulmonary arterial hypertension is a lethal condition, and the management of sepsis in patients with pulmonary arterial hypertension is challenging. As the disease progresses, the right ventricle is susceptible to failure due to a high pulmonary vascular resistance. The limited ability of the right ventricle to increase cardiac output in septic shock makes it difficult to deliver oxygen to the organ and tissues. Intravascular volume replacement and vasoactive drugs should only be considered after a thorough assessment. Priorities of care include improving cardiac output and oxygen delivery by optimizing preload, reducing afterload, and improving contractility.

    The present study was to investigate the association of aldosterone excess and apnea-hypopnea index (AHI) in patients with resistant hypertension. Patients with resistant hypertension were enrolled and baseline characteristics including plasma aldosterone concentration (PAC) and 24 h-urine aldosterone levels were collected and compared between groups with different degrees of AHI as assessed by polysomnography. Association of key variables and AHI was then evaluated by univariate and multiple linear regression analysis. A total of 534 patients with resistant hypertension were enrolled and mean age was 57 ± 11 years. Overall, mean number of AHI was 21.7 ± 9.6 and nearly 92.3% of resistant hypertensive patients had obstructive sleep apnea (OSA). Mean PAC and 24 h-urine aldosterone level was 12.4 ± 6.3 ng/dL and 13.1 ± 6.8 ug, respectively. Compared with other groups, participants in the severe OSA group (AHI ≥ 30) had significantly higher PAC and 24 h-urine aldosterone level. Multiple linear regression analysis showed that PAC and 24 h-urine aldosterone levels were positively associated with AHI, while spironolactone was negatively associated with AHI, independent of age, gender, body mass index, smoking, plasma renin activity and diuretics. OSA is highly prevalent in patients with resistant hypertension and both PAC and 24 h-urine aldosterone level are significantly associated with AHI. PMID:28327653

    Background: The hemodynamic effects of noninvasive ventilation with positive pressure in patients with pulmonary hypertension without left ventricular dysfunction are not clearly established. Objectives: Analyze the impact of increasing airway pressure with continuous positive airway pressure on hemodynamic parameters and, in particular, on cardiac output in patients with variable degrees of pulmonary hypertension. Methods: The study included 38 patients with pulmonary hypertension caused by mitral stenosis without left ventricular dysfunction or other significant valvulopathy. The hemodynamic state of these patients was analyzed in three conditions: baseline, after continuous positive pressure of 7 cmH2O and, finally, after pressure of 14 cmH2O. Results: The population was composed of predominantly young and female individuals with significant elevation in pulmonary arterial pressure (mean systolic pressure of 57 mmHg). Of all variables analyzed, only the right atrial pressure changed across the analyzed moments (from the baseline condition to the pressure of 14 cmH2O there was a change from 8 ± 4 mmHg to 11 ± 3 mmHg, respectively, p = 0.031). Even though there was no variation in mean cardiac output, increased values in pulmonary artery pressure were associated with increased cardiac output. There was no harmful effect or other clinical instability associated with use application of airway pressure. Conclusion: In patients with venocapillary pulmonary hypertension without left ventricular dysfunction, cardiac output response was directly associated with the degree of pulmonary hypertension. The application of noninvasive ventilation did not cause complications directly related to the ventilation systems.

Methods: This study was a prospective uncontrolled longitudinal study. Patients with pulmonary hypertension and vit D deficiency were enrolled into this study. All patients in addition to standard treatment for pulmonary hypertension received cholecalciferol at a dose of 50,000 IU weekly plus calcicare (at a dose of 200 mg magnesium + 8 mg zinc + 400 IU vit D) daily for 3 months. Serum level of 25-hydroxy vit D, serum level of pro-brain natriuretic peptide, six minute walk test (6MWT), peak and mean pulmonary artery pressure, right ventricular size and function, ejection fraction (EF) and New York Heart Association (NYHA) functional class were measured at baseline and after 3 months of treatment. Results: Twenty-two patients with pulmonary hypertension and vit D deficiency were enrolled into the study. At endpoint, the serum vit D level increased significantly to 54.8 ng/ml, the mean of baseline distance of 6MWT increased significantly to 81.6 m and the RV size significantly improved. The mean pulmonary artery pressure also improved after the intervention, but their changes did not reach to statistically significant levels. Conclusion: Vit D replacement therapy in patients with pulmonary arterial hypertension and vit D deficiency results in significant improvement of right ventricular size and 6 MWT. Moreover, mean pulmonary artery pressure improves nonsignificantly. This issue requires further studies with long-term follow-up period. PMID:27999642

    We sought to explore the pulmonary haemodynamic changes in rheumatic mitral stenosis patients with secondary pulmonary hypertension. The pulmonary artery resistance and compliance of 35 patients with rheumatic mitral stenosis and 12 controls without cardiopulmonary vascular disease were evaluated by using an improved method, which is based on making calculations with parameters obtained from right heart catheterisation. The results are as follows: (1) pulmonary artery compliance in patients with secondary pulmonary hypertension was significantly lower than that of the control group (P<0.01); (2) linear correlation analyses showed that preoperative mean pulmonary artery pressure (mPAP) closely correlated with zero-pressure compliance in the mitral stenosis group (r=-0.745, P<0.05); (3) PAP and pulmonary vascular resistance decreased significantly in both groups with mitral stenosis after infusing 0.5 μg kg(-1) min(-1) of sodium nitroprusside (P<0.01). The pulmonary zero pressure compliance and mean pressure compliance increased significantly in the group with mild pulmonary hypertension; whereas in the severe group, the mean compliance changed with significance as the mPAP decreased (1.51 ± 0.59 vs 1.81 ± 0.77 ml/mmHg), however no significant change occurred in the pulmonary zero pressure compliance (2.35 ± 1.24 ml/mmHg vs. 2.24 ± 1.53 ml/mmHg, P>0.05) The walls of pulmonary artery vessels in patients with pulmonary hypertension secondary to rheumatic mitral stenosis appeared to be remodelled by varying degrees as indicated by their haemodynamic properties. Structural remodelling may be a factor affecting preoperative pulmonary artery pressure. Mitral stenosis patients with severe pulmonary hypertension have significantly lower responses to sodium nitroprusside possibly due to aggradation and deposition of collagen in the artery walls, decreasing constriction and dilation, or atrophy of smooth muscle cells.

    To estimate the relationship between type D personality and essential hypertension among patients visiting their GPs for any health problem, 101 hypertensive and 138 nonhypertensive patients were consecutively recruited and assessed using the Type D Personality Scale (DS14). The predictive value of type D personality was determined using a logistic regression model, taking into account the differences in recognized confounders between groups. Type D personality in the hypertension group was twice as frequent as in the no hypertension group and hypertension was more frequent among type D than non-type D patients. Logistic regression showed a significant predictive value of type D personality for hypertension, adjusting for sex, age, body mass index, family history of hypertension, living condition, education, and employment. Therefore, type D personality was strongly related to hypertension and it was a noteworthy predictor of hypertension in a real-world cohort of primary care patients.

    Background Taiwan has the highest renal disease incidence and prevalence in the world. We evaluated the association of statin and renin–angiotensin system inhibitor (RASI) use with dialysis risk in hypertensive patients. Methods Of 248,797 patients who received a hypertension diagnosis in Taiwan during 2001–2012, our cohort contained 110,829 hypertensive patients: 44,764 who used RASIs alone; 7,606 who used statins alone; 27,836 who used both RASIs and statins; and 33,716 who used neither RASIs or statins. We adjusted for the following factors to reduce selection bias by using propensity scores (PSs): age; sex; comorbidities; urbanization level; monthly income; and use of nonstatin lipid-lowering drugs, metformin, aspirin, antihypertensives, diuretics, and beta and calcium channel blockers. The statin and RASI use index dates were considered the hypertension confirmation dates. To examine the dose–response relationship, we categorized only statin or RASI use into four groups in each cohort: <28 (nonusers), 28–90, 91–365, and >365 cumulative defined daily doses (cDDDs). Results In the main model, PS-adjusted hazard ratios (aHRs; 95% confidence intervals [CIs]) for dialysis risk were 0.57 (0.50–0.65), 0.72 (0.53–0.98), and 0.47 (0.41–0.54) in the only RASI, only statin, and RASI + statin users, respectively. RASIs dose-dependently reduced dialysis risk in most subgroups and in the main model. RASI use significantly reduced dialysis risk in most subgroups, regardless of comorbidities or other drug use (P < 0.001). Statins at >365 cDDDs protected hypertensive patients against dialysis risk in the main model (aHR = 0.62, 95% CI: 0.54–0.71), regardless of whether a high cDDD of RASIs, metformin, or aspirin was used. Conclusion Statins and RASIs independently have a significant dose-dependent protective effect against dialysis risk in hypertensive patients. The combination of statins and RASIs can additively protect hypertensive patients against dialysis

    Background and Objectives It is thought that patients with diabetes mellitus (DM) have a poor prognosis after an acute myocardial infarction (AMI), but the effect of diabetes on the outcomes of hypertensive patients with AMIs has not been elucidated in the Korean population. The aim of this study was to investigate the effects of diabetes on long-term clinical outcomes following AMIs in patients with hypertension. Subjects and Methods Using data from the Korea Acute Myocardial Infarction Registry (November 2005 to December 2006), 2,233 hypertensive patients with AMIs were grouped as follows based on the presence of DM: group I, diabetic hypertension (n=892, 544 men, mean age=66.2±10.9 years); and group II, non-diabetic hypertension (n=1341, 938 men, mean age=63.9±12.8 years). The primary study outcomes included in-hospital death and major adverse cardiac events (MACE; cardiac death, myocardial infarction (MI), repeat percutaneous coronary intervention, and coronary artery bypass surgery) at the 1 year follow-up. Results Hypertensive patients with DM were older and more likely to be women. The diabetic group had lower blood pressure (p<0.001), a lower left ventricular ejection fraction (p<0.001), a more severe degree of heart failure (p<0.001), a longer duration of coronary care unit admission (p<0.001), and a higher incidence of hyperlipidemia (p=0.007). The N-terminal pro-brain natriuretic peptide level (4602.5±8710.6 pg/mL vs. 2320.8±5837.9 pg/mL, p<0.001) was higher and the creatinine clearance (62.4±29.9 mL/min vs. 73.0±40.8 mL/min, p<0.001) was lower in the diabetic group than the non-diabetic group. Coronary angiographic findings revealed more frequent involvement of the left main stem (p=0.002) and multiple vessels (p<0.001) in the diabetic group. The rate of in-hospital death was higher in the diabetic group (p<0.001). During follow-up, the rates of composite MACE at 1 month, 6 months, and 12 months were higher in the diabetic group (p<0

    Telemedicine-based medication management improves hypertension control, but has been evaluated primarily in patients with low antihypertensive drug counts. Its impact on patients taking three or more antihypertensive agents is not well-established. To address this evidence gap, the authors conducted an exploratory analysis of an 18-month, 591-patient trial of telemedicine-based hypertension medication management. Using general linear models, the effect of medication management on blood pressure for patients taking two or fewer antihypertensive agents at study baseline vs those taking three or more was compared. While patients taking two or fewer antihypertensive agents had a significant reduction in systolic blood pressure with medication management, those taking three or more had no such response. The between-subgroup effect difference was statistically significant at 6 months (-6.4 mm Hg [95% confidence interval, -12.2 to -0.6]) and near significant at 18 months (-6.0 mm Hg [95% confidence interval, -12.2 to 0.2]). These findings suggest that baseline antihypertensive drug count may impact how patients respond to hypertension medication management and emphasize the need to study management strategies specifically in patients taking three or more antihypertensive medications.

    Pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) are subgroups of pulmonary hypertension and are considered rare diseases. Understanding how endpoints of clinical trials (and patient registry studies) of patients with PAH and CTEPH are associated with patient outcomes is important in order to address the concerns of patients, health care providers, decision makers, and payers. The purpose of this review was to examine how endpoints used in clinical trials and patient registry studies are associated with outcomes of patients with PAH and CTEPH. A PubMed literature search was conducted to retrieve published studies, including randomized phase III clinical trials and observational studies, from years 2000 to May 2015 that evaluated the associations between change in 6-minute walking distance (6MWD), 6MWD thresholds, change in World Health Organization functional class (WHO-FC), and time to clinical worsening with outcomes of patients with PAH and CTEPH. Based on this review of published literature, a reduction in 6MWD as a criterion for PAH worsening, a deterioration in WHO-FC, and delay in the time to clinical worsening are clinically meaningful trial endpoints and are associated with outcomes of patients with PAH and CTEPH. Utilization and standardization of these endpoints will be useful for comparing interventions of clinical trials and therapies. Hospitalizations are frequent among patients with PAH and CTEPH, and total health care costs are high. From a U.S. payer perspective, clinical worsening is an important composite endpoint in that it includes hospitalization, which can be transformed into a preventative cost value associated with efficacious treatment of patients with PAH and CTEPH. In view of the greater number of medications available to treat PAH, the introduction of the first approved therapy to treat CTEPH, and the increasing use of combination pharmacotherapy, reliable prognostic markers of treatment

    Most renal neoplasms in adults are epithelial in origin and mesenchymal tumors are rarely encountered. Vascular tumors and tumor-like lesions account for a very small subset. Hemangioma of the kidney is a rarely seen benign vascular neoplasm that probably arises from angioblastic cells. Its general sign is macroscopic hematuria with or without pain. Preoperative diagnosis is difficult or impossible. Previously, spontaneous rupture of the kidney caused by renal hemangioma was not reported in the English literature. In this study, two cases with a history of nephrogenic hypertension who presented with spontaneous renal rupture are presented. There wasn’t any trauma history in the background of our patients. A long-standing nephrogenic hypertension was present in both patients. Patients underwent radical nephrectomy due to rupture of the renal tumor. In histopathological examination, capillary hemangioma was detected in the renal medulla in both cases. Patients didn’t need antihypertensive therapy during the postoperative period. PMID:26623154

    Grading of essential hypertension according to blood pressure (BP) level may not adequately reflect clinical heterogeneity of hypertensive patients. This study was carried out to explore clinical phenotypes in essential hypertensive patients using cluster analysis. This study recruited 513 hypertensive patients and evaluated BP variations with ambulatory blood pressure monitoring. Four distinct hypertension groups were identified using cluster analysis: (1) younger male smokers with relatively high BP had the most severe carotid plaque thickness but no coronary artery disease (CAD); (2) older women with relatively low diastolic BP had more diabetes; (3) non-smokers with a low systolic BP level had neither diabetes nor CAD; (4) hypertensive patients with BP reverse dipping were most likely to have CAD but had least severe carotid plaque thickness. In binary logistic analysis, reverse dipping was significantly associated with prevalence of CAD. Cluster analysis was shown to be a feasible approach for investigating the heterogeneity of essential hypertension in clinical studies. BP reverse dipping might be valuable for prediction of CAD in hypertensive patients when compared with carotid plaque thickness. However, large-scale prospective trials with more information of plaque morphology are necessary to further compare the predicative power between BP dipping pattern and carotid plaque. PMID:28266630

    Northern Africans constitute one of the largest immigrant groups in France; however, limited data are available on their cardiovascular risk factors. We carried out a retrospective cross-sectional study in a French hypertension unit, comparing 719 patients born in Northern Africa to 3558 controls born in Europe, individually matched for age and sex. Using a Bonferroni adjusted alpha-level=0.001, we found no significant difference between the groups for blood pressure levels, anti-hypertensive treatment, prevalence of target organ damage or the proportion of patients with secondary hypertension. However, patients of both sexes born in Northern Africa were less likely to take regular physical exercise than their controls. In addition, women born in Northern Africa were less often current or former smokers than their European counterparts (19.9% vs 30.5%, p < 0.001), but had a higher body mass index (28.5 vs 26.8 kg/m(2), p < 0.001) and a higher prevalence of diabetes (19.1% vs 8.9%, p < 0.001 after adjusting for BMI). These results suggest that targeted lifestyle interventions, including regular physical exercise, could be proposed to prevent weight gain and decrease the incidence of diabetes in hypertensive women born in Northern Africa and living in western countries.

    The portal-systemic venous shunt is uncommon in patients without portal hypertension. We present two cases of portal-systemic encephalopathy due to extrahepatic shunt without liver cirrhosis and portal hypertension. Two women in their seventies were admitted to our hospital because of recurrent episodes of altered sensorium, drowsiness, slurred speech, disorientation, asterexis and high blood ammonia levels. There was no history of abdominal surgery or abdominal trauma. Clinical examination revealed no signs of portal hypertension or stigmata of chronic liver diseases. Brain CT and MRI scanning were unremarkable except for a high intensity signal in the basal ganglia on T1 weighted MRI images. Laboratory tests were almost normal except for the hyperammonemia occurring on several occasions. There was no evidence of liver cirrhosis by imaging. However, color Doppler showed an extra-hepatic shunt in both patients and pulsed Doppler showed decreased velocity and volume of the portal venous flow. These sonographic findings were confirmed during percutaneous transhepatic portography (PTP). Portal pressures measured during PTP were 9 and 11 mmHg. Needle biopsy ruled out idiopathic portal hypertension and liver cirrhosis. The diagnosis was portal systemic encephalopathy due to extra-hepatic portosystemic venous shunting. Both patients were treated by embolization of the shunting vessel with metallic coils.

    The efficacy and safety profiles of barnidipine in the treatment of hypertension were evaluated in an open parallel-group study. Fifty-nine Chinese patients with mild-to-moderate essential hypertension were randomized to receive either barnidipine or felodipine (5 mg once daily, titrated to 10 mg or 15 mg once daily, as indicated) for 12 weeks. Both drugs reduced blood pressures significantly with > or = 68% of cases obtaining marked or moderate blood pressure reduction. Mean reductions in systolic and diastolic blood pressure for barnidipine treatment were 23.7 +/- 13.5 mmHg and 12.7 +/- 7.9 mmHg, and for felodipine, 24.3 +/- 18.4 mmHg and 14.5 +/- 10.0 mmHg, respectively. There was no significant difference between these two drugs in anti-hypertensive effect, heart rate, laboratory measurements or incidence of adverse events. The only difference was that more patients taking felodipine experienced palpitations. We conclude that barnidipine has similar efficacy and a similar safety profile to felodipine in the treatment of mild-to-moderate essential hypertension in Chinese patients.

    Organ transplantation is the therapeutic option of choice in the appropriate patient with end-organ disease. A major comorbidity after the transplant is the development of hypertension which is a risk factor for cardiovascular disease. Cardiovascular disease is the most common cause of death in this population even when there is a functioning graft. It is essential to evaluate post-transplant hypertension not only in the office setting but at home and at night as well. Hence, the use of 24-h ambulatory blood pressure monitoring in both diagnosis and long-term care of this patient population is paramount. Factors involved in uncontrolled hypertension include the donor, recipient, and those specific to the transplant such as immunosuppressive drug exposure. The major offending immunosuppressive agents belong to the calcineurin inhibitor class. The therapy of post-transplant hypertension involves pharmaceutical and non-pharmaceutical interventions that should be tailored to the specific patient and type of transplant. There is clearly a need for more definitive data and quality studies in both the renal and non-renal transplant populations.

    Abstract Proactive attitude of hypertensive patients seeking follow-up services (FUS) lies at the core of self-efficacy. However, few evidence have shown the activeness of seeking FUS in the context of blood pressure control among hypertensive patients. Improvements in follow-up visits may not just by services itself cause better control of blood pressure among hypertensive patients, rather due to the patient's pro-active attitude of the patient in seeking FUS. A cross-sectional study was carried out in selected rural regions of China to explore the association between blood pressure control and sociodemographic and economic variables and activeness of hypertensive patients in seeking FUS. The primary clinical outcome for this study was blood pressure control (systolic blood pressure <140 mmHg or diastolic blood pressure <90 mmHg) Out of the total 2321 participants with hypertension aged 35 years or older participated in this survey. Number of proactive FUS seekers were 3.17 times greater than those of passive seekers (odds ratio [OR] = 3.17, 95% confidence interval [CI] = 2.56–3.93, P < 0.001). In all subgroups, hypertensive patients who were seeking FUS actively were more likely to control blood pressure better than those seeking FUS passively. Proactive attitude of seeking follow-up services can improve blood pressure control among hypertensive patients. PMID:27057859

    The prognostic importance of the nocturnal systolic blood pressure (SBP) fall, adjusted for average 24-hour SBP levels, is unclear. The Ambulatory Blood Pressure Collaboration in Patients With Hypertension (ABC-H) examined this issue in a meta-analysis of 17 312 hypertensives from 3 continents. Risks were computed for the systolic night-to-day ratio and for different dipping patterns (extreme, reduced, and reverse dippers) relative to normal dippers. ABC-H investigators provided multivariate adjusted hazard ratios (HRs), with and without adjustment for 24-hour SBP, for total cardiovascular events (CVEs), coronary events, strokes, cardiovascular mortality, and total mortality. Average 24-hour SBP varied from 131 to 140 mm Hg and systolic night-to-day ratio from 0.88 to 0.93. There were 1769 total CVEs, 916 coronary events, 698 strokes, 450 cardiovascular deaths, and 903 total deaths. After adjustment for 24-hour SBP, the systolic night-to-day ratio predicted all outcomes: from a 1-SD increase, summary HRs were 1.12 to 1.23. Reverse dipping also predicted all end points: HRs were 1.57 to 1.89. Reduced dippers, relative to normal dippers, had a significant 27% higher risk for total CVEs. Risks for extreme dippers were significantly influenced by antihypertensive treatment (P<0.001): untreated patients had increased risk of total CVEs (HR, 1.92), whereas treated patients had borderline lower risk (HR, 0.72) than normal dippers. For CVEs, heterogeneity was low for systolic night-to-day ratio and reverse/reduced dipping and moderate for extreme dippers. Quality of included studies was moderate to high, and publication bias was undetectable. In conclusion, in this largest meta-analysis of hypertensive patients, the nocturnal BP fall provided substantial prognostic information, independent of 24-hour SBP levels.

    Abstract Objectives. To evaluate the long-term efficacy and safety of certolizumab pegol (CZP) plus methotrexate treatment and to assess the efficacy of two CZP maintenance dosing schedules in Japanese rheumatoid arthritis (RA) patients with an inadequate response to methotrexate. Methods. J-RAPID double-blind patients were entered into an open-label extension (OLE) study. Patients withdrawn due to lack of efficacy at 16 weeks and double-blind completers without a week-24 American College of Rheumatology (ACR) 20 response received CZP 200 mg every other week (Q2W) plus methotrexate. Double-blind completers with week-24 ACR20 responses were randomized to CZP 200 mg Q2W plus methotrexate or CZP 400 mg every 4 weeks plus methotrexate. Results. The ACR20/ACR50/ACR70 response rates of double-blind completers (n = 204) were 89.7%/67.2%/36.3% at OLE entry and 95.6%/84.8%/58.3% at 52 weeks, respectively. Other clinical, functional and radiographic outcomes were sustained with long-term CZP plus methotrexate. Long-term treatment with CZP was well-tolerated with no new unexpected adverse events observed. The efficacy and safety of CZP treatment were similar between the two dosing schedules. Conclusions. Continued CZP administration with methotrexate maintained efficacy over 52 weeks and was well-tolerated for Japanese RA patients. No obvious differences in clinical efficacy and safety were observed between the two dosing schedules, giving flexibility in maintenance administration schedules. PMID:24593170

    Ambulatory blood pressure (BP) recording was performed in 57 untreated hypertensive patients by means of the "Spacelabs" non-invasive apparatus. Patients were divided into two groups according to BP measurements previously made during medical consultation. Group I comprised 25 "permanently hypertensive" patients (diastolic BP always above 95 mmHg) and group II, 32 "occasionally hypertensive" patients (diastolic BP sometimes normal, sometimes above 95 mmHg). The same circadian rhythm was observed in both groups. The mean ambulatory BP level was significantly higher (p less than 0.001) in group I patients than in group II patients, either over the whole of the 24-hour period (142.0/88.0 versus 122.7/75.3 mmHg), or in day time (149.0/92.5 versus 128.2/78.9 mmHg) or at night (128.0/80.1 versus 111.5/68.0 mmHg). In contrast, there did not seem to be any significant difference between the two groups in relative long-term variability of BP, expressed as the standard deviation/mean BP values ratio. Comparison with clinical data showed that BP values measured during consultation (160/103 mmHg in group I, 143/94 mmHg in group II) were higher than ambulatory values and, chiefly, that there was very poor correlation between the two measurement methods, precluding any extrapolation. Automatic ambulatory BP recording provides for more accurate evaluation of hypertensive patients, enabling emotional "artefacts" to be excluded and patients "reactivity" to their socio-professional environment to be assessed. However, in the absence of sufficient epidemiological data, doctors should not feel authorized to base their therapeutic decisions on the sole data supplied by ambulatory BP recordings.

    This study examined the efficacy of teaching emotional self-regulation techniques supported by heart rhythm coherence training (emWave Personal Stress Reliever) as a means to quickly lower blood pressure (BP) in patients diagnosed with hypertension. Previous studies have demonstrated systemic reductions in BP in both high stress populations and patients diagnosed with hypertension using this approach, but to the best of our knowledge, an investigation of their ability to produce immediate reductions in BP had not been published in the medical literature. The study was a randomized controlled design with 62 hypertensive participants who were divided into three groups. Group 1 was taking hypertensive medication, was taught self-regulation technique, and used heart rate variability coherence (HRVC) training devices. Group 2 was not yet taking medication and was trained in the same intervention. Group 3 was taking hypertensive medication but did not receive the intervention and was instructed to relax between the BP assessments. An analysis of covariates was conducted to compare the effectiveness of three different interventions on reducing the participants' BP. The use of the self-regulation technique and the HRVC-monitoring device was associated with a significantly greater reduction in mean arterial pressure in the two groups who used the intervention as compared with the relaxation-plus-medication group. Additionally, the group not taking medication that used the intervention also had a significantly greater reduction in systolic BP than the relaxation- plus-medication group. These results suggest that self-regulation techniques that incorporate the intentional generation of positive emotions to facilitate a shift into the psychophysiological coherence state are an effective approach to lowering BP. This approach to reducing BP should be considered a simple and effective approach that can easily be taught to patients to quickly lower their BP in stressful

    Background Left ventricular hypertrophy (LVH) is an independent cardiovascular risk factor in patients with essential hypertension. The main objective of this study was to assess the echocardiographic prevalence of left ventricular hypertrophy in patients with hypertension, its risk factors and effect of antihypertensive drugs on its prevalence. Methods A hospital based cross sectional study was conducted on 200 hypertensive patients on treatment in southwest Ethiopia. A pretested structured questionnaire was used to collect data from participants and their clinical records. Blood pressure and anthropometric measurements were taken according to recommended standards. Left ventricular mass was measured by transthoracic echocardiography. Associations between categorical variables were assessed using chi-square test and odds ratio with 95% confidence interval. Logistic regression model was done to identify risks factors of LVH. P values of < 0.05 were considered as statistically significant. Results The mean age, systolic blood pressure, diastolic blood pressure and body mass index were 55.7 ± 11.3 years, 139.2 ± 7.7 mmHg, 89.2 ± 5.7 mmHg and 24.2 ± 3.4 Kg/m2 respectively. The overall prevalence of LVH among these study subjects was 52%. Age ≥50 years (OR: 3.49, 95% CI 1.33-9.14, P = 0.011), female gender (OR: 7.69, 95% CI 3.23-20.0, P < 0.001), systolic blood pressure ≥140 mmHg (OR: 2.85, 95% CI 1.27-6.41, P = 0.011), and duration of hypertension (OR: 3.59, 95% CI 1.47-8.76, P = 0.005) were independent predictors of left ventricular hypertrophy. Angiotensin converting enzyme (ACE) inhibitors were the only antihypertensive drugs associated with lower risk of left ventricular hypertrophy (OR: 0.08, 95% CI 0.03-0.19, p < 0.001). Conclusions Left ventricular hypertrophy was found to be highly prevalent in hypertensive patients in Ethiopia. ACE inhibitors were the only antihypertensive drugs associated with reduced risk

    Several large epidemiological studies have reported an inverse relationship between blood pressure and physical activity. However, longitudinal intervention studies are more appropriate for assessing the effects of physical activity. We performed meta-analyses of randomized controlled trials involving dynamic aerobic endurance training or resistance training. The meta-analysis on endurance training involved 72 trials and 105 study groups. After weighting for the number of trained participants, training induced significant net reductions in resting and daytime ambulatory blood pressure of, respectively, 3.0/2.4 mmHg (P<0.001) and 3.3/3.5 mmHg (P<0.01). The reduction in resting blood pressure was more pronounced in the 30 hypertensive study groups (-6.9/-4.9) than in the others (-1.9/-1.6; P<0.001 for all). Systemic vascular resistance decreased by 7.1% (P<0.05), plasma norepinephrine by 29% (P<0.001), and plasma renin activity by 20% (P<0.05). Body weight decreased by 1.2 kg (P<0.001), waist circumference by 2.8 cm (P<0.001), percentage body fat by 1.4% (P<0.001) and the homeostasis model assessment index of insulin resistance by 0.31 units (P<0.01); high-density lipoprotein cholesterol increased by 0.032 mmol/l (P<0.05). Resistance training has been less well studied. A meta-analysis of nine randomized controlled trials (12 study groups) on mostly dynamic resistance training revealed a weighted net reduction in blood pressure of 3.2 (P=0.10)/3.5 (P<0.01) mmHg associated with exercise. Endurance training decreases blood pressure through a reduction in systemic vascular resistance, in which the sympathetic nervous system and the renin-angiotensin system appear to be involved, and favourably affects concomitant cardiovascular risk factors. The few available data suggest that resistance training can reduce blood pressure. Exercise is a cornerstone therapy for the prevention, treatment and control of hypertension.

    Objective: To understand the practices and effects of different measures for blood pressure control in hypertension patients. Methods: Patients who have known hypertension from the subjects of "2014 Beijing adult (aged 18-79 years) chronic diseases and risk factors survey" were selected. The choices of different hypertension control measures, the relationship between the measures and demographic characteristics of hypertension patients, and the effects of different control measures were analyzed. Results: A total of 2 229 known hypertension patients were included, the analysis was conducted through a questionnaire survey. Those who answered "never taking any measures" , "taking medication according to doctor's instructions" and "taking medication when blood pressure rose" accounted for 7.0%, 79.8% and 8.3%, respectively. Those who had "diet control" , "physical exercises" and "blood pressure monitoring" accounted for 22.4%, 23.7% and 22.1%, respectively. In terms of "taking medicine according to doctor's instructions" , women (84.3%), those aged ≥60 years (87.6%), those living in urban area (81.5%), those living alone (83.8%), and Beijing local residents (82.3%) had higher compliance rates. As for "diet control" , women (24.4%), those aged ≥60 years (25.8%) and those with educational level of college or above (29.5%) had better practices. In terms of "physical exercise" , those aged ≥60 years (27.9%), those living in urban area (25.3%), those with educational level of college or above (32.5%) had better practice. Women (24.2%) and those aged ≥60 years (28.4%) had higher "blood pressure monitoring" rate. More men (9.7%), those aged 18-44 years (14.7%), those with educational level of high school (9.3%), the unmarried (18.2%), and non-Beijing local residents (14.7%) answered "never taking any measure" , and in terms of "taking medication when blood pressure rose" , non-Beijing local residents (12.8%) had higher rate.

    Objective. This study evaluated the prevalence, awareness, and type of treatment for hypertension in Brazil in patients with type 1 diabetes (T1D). Methods. This was a cross-sectional, multicenter study that was conducted from December 2008 to December 2010 in 28 public clinics located in 20 Brazilian cities. Results. A total of 3,591 patients were studied, 56% female, average age 21.2 ± 11.7 years, with a median duration of diabetes 9.6 ± 8.1 years. Blood pressure levels were available for a total of 3,323 patients and 689 (19.2%) patients were hypertensive. Hypertensive patients were older, exhibited longer duration of diabetes, and had higher body mass index (BMI), total cholesterol, triglycerides, and LDL-C values (P < 0.001, for all comparisons), but only 370 (53.7%) received treatment. Patient awareness of hypertension was documented in 453 (65.5%) patients. However, only 76 (22.9%) of the treated patients attained the target systolic (sBP) and diastolic blood pressures (dBP). Conclusions. Our results demonstrate that a large number of T1D patients with hypertension do not receive appropriate treatment; few of the treated T1D patients achieved the target sBP and dBP values. Greater attention should be paid to blood pressure evaluation, hypertension diagnosis, and treatment of T1D patients in Brazil. PMID:23533714

    The long-term effects of indapamide or hydrochlorothiazide on blood presssure and renal function were examined in patents with impaired renal function and moderate hypertension. Both drugs controlled hypertension and blood pressure remained normal during the 2 years of the study. Despite this comparable control of hypertension, indapamide therapy was associated with a 28.5 +/- 4.4% increase in creatinine clearance, whereas treatment with hydrochlorothiazide was associated with a 17.4 +/- 3.0% decrease in creatinine clearance. The results of the study indicate that indapamide is superior to hydrochlorothiazide in the treatment of patients with impaired renal function and moderate hypertension.

    Recent advances in cardiac magnetic resonance imaging (CMR) have allowed for characterization of blood flow in the right ventricle (RV), including calculation of vorticity and circulation, and qualitative visual assessment of coherent flow patterns. In this study, we investigate qualitative and quantitative differences in right ventricular hemodynamics between subjects with pulmonary hypertension (PH) and normal controls. Fifteen (15) PH subjects and 10 age-matched controls underwent same day 3D time resolved CMR and echocardiography. Echocardiography was used to determine right ventricular diastolic function as well as pulmonary artery systolic pressure (PASP). Velocity vectors, vorticity vectors, and streamlines in the RV were visualized in Paraview and total RV Early (E) and Atrial (A) wave diastolic vorticity was quantified. Visualizations of blood flow in the RV are presented for PH and normal subjects. The hypothesis that PH subjects exhibit different RV vorticity levels than normals during diastole is tested and the relationship between RV vorticity and PASP is explored. The mechanics of RV vortex formation are discussed within the context of pulmonary arterial pressure and right ventricular diastolic function coincident with PH.

    The water sodium overload is a factor of morbi-mortality and its treatment is one of the markers of adequacy of the hemodialysis treatment. Its first clinical assessment was improved by tools such as echocardiography and ultrasonography of the inferior vena cava, the per-dialytic curve of plasma volume, measuring BNP or proBNP and by impedancemetry. The combination of the evaluation of these parameters and of the clinical situation allows one to assess the extracellular overload, the state of the blood volume and the potential of plasma refilling. The latter is a key factor of the per-dialytic hemodynamic tolerance. It is itself a determining factor in weight can be achieved at the end of the session. Getting the "dry" weight can require modifications of the prescriptions of the hemodialysis sessions, a filling by albumin even a drugs support. Finally, the overload treatment is the central part of the treatment of arterial hypertension, which has to benefit however often from antihypertensive treatment the profit of which is demonstrated.

    Background Measurement of epicardial adipose tissue (EAT) is suggested as a novel cardiometabolic risk factor. Microalbuminuria is a marker of endothelial dysfunction and is associated with an increased risk for cardiovascular disease in patients with systemic hypertension. The aim of this study was to investigate the relationship of echocardiographic epicardial adipose tissue (EAT) thickness and microalbuminuria in hypertensive patients. Methods 75 essential hypertensive patients were included into the study. All subjects underwent transthoracic echocardiography to measure EAT thickness. Spot urine sample was collected for the assessment of microalbuminuria. Patients were divided into two groups according to their spot urine albumin to creatinine ratio (UACR); Group 1 included normoalbuminuria (0-30 μg/mg); and Group 2: included microalbuminuria (30-300 μg/mg). Thereafter, we evaluated patient characteristics including smoking status, blood pressure, body mass index (BMI), antihypertensive treatment, statin therapy and serum levels of total cholesterol, low-density lipoprotein cholesterol, triglicerides, albumin, C-reactive protein (CRP), creatinine and hemoglobin. Results There was no difference in baseline characteristics between Group 1 and Group 2. Patients with microalbuminuria had significantly higher mean EAT thickness values compared to the normoalbuminuria group (7.1 ± 0.9 vs. 6.6 ± 0.9, p = 0.01). There were positive significant correlations between EAT and age (r = 0.267, p = 0.020), serum creatinine (r = 0.292, p = 0.01), UACR (r = 0.251, p = 0.03), left ventricular mass (r = 0.257, p = 0.03) and left ventricular mass index (r = 0.242, p = 0.04). UACR was independently associated with EAT (p = 0.01) after adjustments were made for age and BMI. Conclusions Epicardial Adipose Tissue (EAT) thickness could be associated with microalbuminuria in patients with essential hypertension. This association could support the recognition of EAT as a credible

    Background: Several studies have examined the links between hypertension, vascular damage, and cognitive impairment. The functions most commonly involved seem to be those associated with memory and executive function. Aims: 1) to report the cognitive evolution in a cohort of hypertensive patients, 2) to identify the affected domains, and 3) to correlate the results obtained with blood pressure measurements. Materials and Methods: Observational 6-year follow-up cohort study including both males and females aged ≥65 and ≤80 years, and hypertensive patients under treatment. Patients with a history of any of the following conditions were excluded: stroke, transient ischemic attack, diabetes mellitus, atrial fibrillation, cardiac surgery, dementia, or depression. Four neurocognitive evaluations were performed (at baseline and every 2 years). The tests used evaluated memory and executive function domain. Blood pressure was measured on every cognitive evaluation. Results: Sixty patients were followed for 76.4 ± 2.8 months. The average age at baseline was 72.5 ± 4.2 and 77.9 ± 4.6 at 6 years (65% were women). Two patients were lost to follow up (3.3%) and 8 patients died (13.3%).The density incidence for dementia was 0.6% patients per year (pt/y) (n = 3) and for depression was 1.6% pt/y (n = 12). No changes were observed in either memory impairment or the Mini Mental State Examination (MMSE) results (p = ns) during follow-up. A progressive impairment of the executive function was shown regardless of the blood pressure measurements. Conclusion: 1) the incidence of dementia doubled to general population, 2) the initial memory impairment did not change during the evaluation period, 3) cognitive impairment worsened in the areas related to executive function (prefrontal cortex) regardless of the adequacy of anti-hypertensive treatment and blood pressure values.

    We assessed the efficacy and safety of sitagliptin compared with α-glucosidase inhibitor (αGI) in 120 of Japanese patients with type 2 diabetes mellitus (T2DM) inadequately controlled on stable ≤2 mg/day glimepiride alone [mean hemoglobin A1c (HbA1c) 7.7%] by the randomized, active-controlled, non-inferiority trial. Patients were randomly assigned to receive additional sitagliptin or αGI for 24 weeks. The primary endpoint was change in HbA1c from baseline to week 12. After 12 weeks, sitagliptin reduced HbA1c by -0.44% (p < 0.001) relative to αGI. At 24 weeks, the reduction was almost identical between the groups (-0.091%, p = 0.47). Gastrointestinal disorders were more common with αGI than with sitagliptin, but only minor hypoglycaemia occurred in both groups at similar frequency. These data suggested that sitagliptin was not inferior to αGI for reduction of HbA1c in Japanese T2DM patients receiving glimepiride alone, and well tolerated with minimum risk of gastrointestinal symptoms and hypoglycaemia.

    Exercise intolerance and heart failure with preserved ejection fraction are common in females. Recently, arterial stiffness has been suggested to be a significant contributor in the development of heart failure. How gender difference affects arterial stiffening and its response to exercise is not well known. We hypothesized that arterial elastance index during exercise would be more abnormal in females with hypertension than males. Arterial elastance index was estimated as arterial end systolic pressure/stroke volume controlled for body surface area and was measured at rest and during graded supine bicycle exercise (25 watts, 3-minute increments) in 298 patients with hypertension (149 males; 149 females; mean age, 59). The subjects were divided into 2 groups by gender. Exercise duration was significantly shorter in females compared to males (692+/-222 versus 483+/-128 seconds, P<0.001). Although arterial elastance index at baseline was significantly higher in males, the magnitude of increase was steeper in females with the magnitude of change at 75 W of exercise being significantly higher in females compared to males (0.69+/-0.83 versus 0.43+/-0.69, P=0.018). Arterial elastance index at each stage of exercise up to 75 W was independently associated with decreased exercise duration. In conclusion, despite lower arterial elastance index at rest, the increase during exercise was steeper in women with hypertension, suggesting a gender-related difference in dynamic arterial stiffness. The arterial elastance index during exercise was significantly associated with exercise duration in patients with hypertension.

    The assessment of potassium (K) effects in hypertension involves a history of complex research in cell K function and body K homeostasis. These studies provide evidence for the role of K ions in vascular and renal function, insulin resistance, glucose uptake, and the renin-angiotensin-aldosterone system; and there have been an impressive number of clinical and epidemiologic research relating dietary intake K and regulation of blood pressure. However, the usual technique by which K metabolism is assessed in clinical practice (plasma or serum K) provides no useful data for estimating disorders in cell K transport that occurs in hypertensive patients or that may follow the administration of diuretics, beta-blockers, or nonsteroidal anti-inflammatory drugs. This fact becomes more crucial if associated with the physiologic decline in body K stores occurring after the age of 30 years, which may impair the long-term treatment of hypertensive individuals. In this context, this article presents a review of the clinical and research methods that can be used to assess more accurately K metabolism and cell K physiology in hypertensive patients, including a heritable defect in red blood cell K transport.

    The effect of the anti-hypertensive drug eprosartan on metabolic parameters is currently not extensively documented. We evaluated the effect of eprosartan on parameters involved in atherogenesis, oxidative stress and clotting activity. This open-label unblinded intervention study included 40 adult patients with essential hypertension taking eprosartan. Eprosartan significantly reduced by 8% (p<0.001) the systolic and by 13% (p<.001) the diastolic blood pressure, and in-creased by 24% the time needed to produce oxidative by-products (p=0.001), a marker of oxidative stress. In contrast, ep-rosartan did not alter 8-isoprostane (8-epiPGF2a) levels, another marker of oxidative stress. Additionally, eprosartan re-duced by 14% aspartate aminotransferase and by 21% then alanine aminotransferase activity, while it had a neutral effect on the lipid profile and apolipoprotein levels and did not influence glucose homeostasis, creatinine and uric acid levels. Eprosartan did not affect the clotting/fibrinolytic status (estimated by plasminogen activator inhibitor 1, tissue plasmino-gen activator and a2 antiplasmin levels), or the enzymatic activity of the lipoprotein associated phospholipase A2 (Lp-PLA2) and paraoxonase 1 (PON1). In conclusion, eprosartan should be mainly considered as an anti-hypertensive agent with neutral effects on most of the metabolic parameters in hypertensive patients. PMID:18949087

    Eleven patients with osteoarthritis and mild hypertension completed an 8-week, double-blind crossover study in which 200 mg tiaprofenic acid 3-times daily or placebo were substituted for their normal non-steroidal anti-inflammatory therapy. Systolic blood pressure was significantly higher on tiaprofenic acid therapy than on placebo and plasma renin activity was significantly lower on active treatment. No significant changes were seen in biochemical parameters, though the weight of the patient was also higher on tiaprofenic acid than on placebo. Duration of morning stiffness was also lower on tiaprofenic acid than on placebo. Blood pressure on tiaprofenic acid was not different from baseline readings on other non-steroidal anti-inflammatory drug therapy. This study suggests that tiaprofenic acid, like other non-steroidal anti-inflammatory agents, may interfere with blood pressure control in treated hypertensive patients.

    Twenty-five patients with hypersplenism caused by portal hypertension were treated by repeated partial splenic embolization. Fourteen surviving patients were followed for up to six years showing a good response on peripheral blood count and bleeding tendency. Three patients died in connection with the treatment and another eight died within half a year because of the underlying liver disease. The discomfort and complications of fever, pain, pleural effusion, and abscess formation and the possibility to avoid these by repeated partial embolization under antibiotic cover are discussed. The results are compared with reports in the reviewed actual literature and the splenic embolization is given a place among the means of a successful selective symptomatic treatment of partial hypertension.

We have analyzed the prevalence of PH associated with COPD, its importance in the structure of diseases in patients of older age groups. Frequency of PH in old patients is associated with prevalence of concomitant diseases. Addition of LH to polymorbid complex of old age worsens quality of life and increases mortality. We also present in this article data on the use of modern drugs for the treatment of LH in COPD patients aged 60 years and older.

    Hypertension is the major risk factor for stroke, and genetic factors contribute to its development. Inflammation has been hypothesized to be the key link between blood pressure elevation and stroke. We performed an analysis of the association between inflammatory mediator gene polymorphisms and the incidence of stroke in patients with essential hypertension (EH). The study group consisted of 625 individuals (296 patients with noncomplicated EH, 71 hypertensive patients with ischemic stroke, and 258 control subjects). Both patients and controls were ethnic Tatars originating from the Republic of Bashkortostan (Russian Federation). The analysis has shown that the risk of ischemic stroke was associated with the CXCR2 rs1126579 polymorphism. Our results indicate that among patients with EH, the heterozygous genotype carriers had a higher risk of stroke (OR = 1.72, 95% CI 1.01-2.92), whereas the CXCR2*C/C genotype was protective against stroke (OR = 0.32, 95% CI 0.12-0.83). As shown by the gene-gene interaction analysis, the CXCR2 rs1126579 polymorphism was also present in all genotype/allele combinations associated with the risk of stroke. Genetic patterns associated with stroke also included polymorphisms in the CCL2, CCL18, CX3CR1, CCR5, and CXCL8 (IL8) genes, although no association between these loci and stroke was detected by individual analysis.

    This study evaluated the efficacy and safety of barnidipine for the treatment of mild-to-moderate essential hypertension in Chinese patients. A total of 131 patients were randomized to receive either barnidipine (10 -15 mg) or felodipine (5 - 10 mg) once daily for 4 weeks. Both drugs reduced blood pressure significantly, with > or = 87% of patients obtaining a marked or moderate effect. The mean +/- SD reductions in systolic and diastolic blood pressure were 19.2 +/- 13.6 and 14.4 +/- 7.0 mmHg, respectively, for barnidipine treatment, and 20.3 +/- 11.3 and 14.7 +/- 7.7 mmHg, respectively, for felodipine treatment. There were no significant differences between the two drugs in terms of anti-hypertensive effect, heart rate, laboratory test results or incidence of adverse events. More patients taking felodipine experienced palpitations, but this difference was not statistically significant. Barnidipine is as efficacious and safe as felodipine in the treatment of essential hypertension in Chinese patients.

    The many advantages of (13)C NMR are often overshadowed by its intrinsically low sensitivity. Given that carbon makes up the backbone of most biologically relevant molecules, (13)C NMR offers a straightforward measurement of these compounds. Two-dimensional (13)C-(13)C correlation experiments like INADEQUATE (incredible natural abundance double quantum transfer experiment) are ideal for the structural elucidation of natural products and have great but untapped potential for metabolomics analysis. We demonstrate a new and semiautomated approach called INETA (INADEQUATE network analysis) for the untargeted analysis of INADEQUATE data sets using an in silico INADEQUATE database. We demonstrate this approach using isotopically labeled Caenorhabditis elegans mixtures.

    Previous studies on the relationship between subjective cognitive failures (SCF) and objective cognitive function have shown inconsistent results. In addition, research on the association between SCF and imaging markers of cerebral small vessel disease is limited. We investigated whether SCF in patients with essential hypertension, who are at high risk of cerebral small vessel disease, are associated with objective cognitive function and magnetic resonance imaging manifestations of cerebral small vessel disease. We included 109 patients with hypertension who underwent extensive neuropsychological assessment, including questionnaires measuring SCF and symptoms of anxiety and depression. Brain magnetic resonance imaging was performed to rate the presence of lacunes, cerebral microbleeds, and perivascular spaces, as well as white matter hyperintensities volume. Results showed significant associations between SCF and objectively measured overall cognition (B=-0.02; 95% confidence interval=-0.03 to -0.005), memory (B=0.02; 95% confidence interval=-0.03 to -0.004), and information processing speed (B=-0.02; 95% confidence interval=-0.03 to -0.001) after adjustment for patient characteristics and vascular risk factors. In addition, SCF were associated with the presence of cerebral microbleeds (odds ratio=1.12; 95% confidence interval=1.02-1.23) after adjustment for patient characteristics and vascular risk factors but not with other imaging markers of cerebral small vessel disease. Our study demonstrates that attention for SCF in patients with hypertension is needed because these may point to lower objective cognitive function, which might be as a result of the presence of cerebral microbleeds. Accordingly, this study emphasizes that neuropsychological assessment and brain imaging need to be considered when patients with hypertension report SCF.

    AIM: To determine whether serum vascular endothelial growth factor (VEGF) levels correlates with the severity of liver cirrhosis and whether portal hypertension impacts on the expression of serum VEGF protein. METHODS: Fifty-three patients (mean age 56 ± 2 years) with HCV (n = 26), HBV (n = 13), and cryptogenic liver cirrhosis (n = 14) (Child-Pugh-s class A: 24, B: 19 and C: 12) and normal renal function constitute the patient population, who were all diagnosed by clinical, histological and radiological findings. Six healthy people and six patients with acute hepatitis served as controls. Severity of liver disease was evaluated by the CP score. Serum levels of IGF-1 and VEGF were measured by radioimmunoassay and ELISA, respectively. Portal hypertension was assessed using pulsed Doppler ultrasound. RESULTS: The mean serum VEGF levels in all cirrhotic patients (73 ± 58) were significantly lower than those of healthy controls (360 ± 217, P < 0.01) and acute hepatitis (1123 ± 1261, P < 0.01) respectively. No significant difference in median serum VEGF levels were noted among the different Child-Pugh-s classes (class A: median, 49.4 ng/L, range, 21-260 ng/L, Class B: median 59.9 ng/L; range 21-92, and Class C: median 69; range 20-247 ng/L). A significant correlation was noted between serum VEGF and two accurate parameters of portal hypertension: portal blood flow velocity (r = 06) and spleen size (r = 0.55). No correlation was found between VEGF serum levels and serum albumin, IGF-1, platelets count and aminotrasnferases (r = 0.2, r = 0.1, r = 0.2 and r = 0.2, respectively). CONCLUSION: Circulating VEGF level in patients with liver cirrhosis could not serve as an indicator of the progression of chronic liver disease but rather, they may reflect increased portal hypertension or decreased hepatic regenerative activity or the combination of both.

    2016-01-01

    Background: Both vitamin D deficiency and hypertension are prevalent in the general population. Several observations indicate an association between vitamin D deficiency and high blood pressure. The present case-control study aimed to compare serum 25-hydroxyvitamin D (25-OHD) in hypertensive patients versus healthy controls. Methods: One hundred patients aged 30-60 years with hypertension (HTN) and 100 healthy controls without history of hypertention were compared regarding serum 25-OHD. Blood pressure was measured using standard method and the systolic and diastolic blood pressure more than140 mmHg and 90 mmHg respectively were considered as HTN. Patients and controls with coexistent morbidities, vitamin D supplementation were excluded. The serum levels of 25-OHD, PTH and calcium were measured after obtaining a written informed consent from the patients and taking their blood pressure under standard conditions. In statistical analysis, the two groups were compared using independent t test and chi-square test using SPSS Version 18. Results: The mean age of patients and controls was comparable (53.7±6.4 vs 52.3±7.54 years, P=0.17). Serum 25-OHD in HTN was significantly higher than controls (P=0.001). Conclusion: In the present study, serum 25-OHD level in hypertension was higher than controls. The results contradict with earlier studies indicating an association of HTN with vitamin D deficiency. This issue warrants further investigations in particular the follow-up of serum 25-OHD deficient and sufficient subjects with regard to the development of HTN. PMID:27757200

    In June 2015, a panel of experts gathered in a consensus conference to plan updating recommendations on the management of the hypertensive patient with elevated heart rate (HR), previously released in 2006. The issues examined during that meeting and further discussed by the participants during the following months involved the assessment of HR, the relevance of HR as a cardiovascular risk factor, the definition of tachycardia and the treatment of the hypertensive patient with high HR. For the measurement of resting HR the panel experts recommended that scientific investigations focusing on HR should report information on length of resting period before measurement, information about temperature and environment, method of measurement, duration of measurement, number of readings, time interval between measurements, body position and type of observer. According to the panellists there is convincing evidence that HR is an important risk factor for cardiovascular disease and they suggest to routinely include HR measurement in the assessment of the hypertensive patient. Regarding the definition of tachycardia, the panellists acknowledged that in the absence of convincing data any threshold used to define tachycardia is arbitrary. Similarly, as there are no outcome studies of HR lowering in tachycardia hypertension, the panellists could not make practical therapeutic suggestions for the management of such patients. However, the experts remarked that absence of evidence does not mean evidence against the importance of tachycardia as a risk factor for cardiovascular disease and that long-term exposure to a potentially important risk factor may impair the patient's prognosis. The main aims of the present document are to alert researchers and physicians about the importance of measuring HR in hypertensive patients, and to stimulate research to clarify unresolved issues.

    The main aim of the present study was to investigate the association between epicardial adipose tissue (EAT) and arterial function in patients with asymptomatic hypertension. Patients with hypertension (n = 155) were enrolled consecutively. Patients with decreased arterial compliance (AC) and increased cardioankle vascular index (CAVI) had higher EAT values compared with those with normal AC and CAVI (6.23 ± 1.67 vs 4.91 ± 1.40, P < .001 and 6.02 ± 1.61 vs 4.96 ± 1.46, P = .01, respectively). Analysis using the receiver-operating characteristics curve demonstrated that EAT 5.5 mm constitutes the cutoff value for the presence of increased CAVI with 67% sensitivity and 62% specificity (area under the curve [AUC]: 0.702, 95% confidence interval [CI] 0.590-0.814) and decreased AC with 77% sensitivity and 65% specificity (AUC: 0.756, 95% CI 0.645-0.867). Assessment of EAT during echocardiography examination may provide information on arterial function in patients with asymptomatic hypertension. The link between EAT and arterial stiffness deserves further investigation.

    Rationale: Portopulmonary hypertension (PPHTN) occurs in 6% of liver transplant candidates. The pathogenesis of this complication of portal hypertension is poorly understood. Objectives: To identify genetic risk factors for PPHTN in patients with advanced liver disease. Methods: We performed a multicenter case-control study of patients with portal hypertension. Cases had a mean pulmonary artery pressure >25 mm Hg, pulmonary vascular resistance >240 dynes·s−1·cm−5, and pulmonary capillary wedge pressure ≤15 mm Hg. Controls had a right ventricular systolic pressure < 40 mm Hg (if estimated) and normal right-sided cardiac morphology by transthoracic echocardiography. We genotyped 1,079 common single nucleotide polymorphisms (SNPs) in 93 candidate genes in each patient. Measurements and Main Results: The study sample included 31 cases and 104 controls. Twenty-nine SNPs in 15 candidate genes were associated with the risk of PPHTN (P < 0.05). Multiple SNPs in the genes coding for estrogen receptor 1, aromatase, phosphodiesterase 5, angiopoietin 1, and calcium binding protein A4 were associated with the risk of PPHTN. The biological relevance of one of the aromatase SNPs was supported by an association with plasma estradiol levels. Conclusions: Genetic variation in estrogen signaling and cell growth regulators is associated with the risk of PPHTN. These biologic pathways may elucidate the mechanism for the development of PPHTN in certain patients with severe liver disease. PMID:19218192

    The etiology of essential hypertension includes increased oxidative stress. The role of antihypertensive drug amlodipine as an antioxidant and the benefit of addition of vitamin C, an antioxidant to antihypertensive therapy were studied. Forty male patients of essential hypertension were randomly divided into two groups and treated with 5 mg amlodipine. In addition one group also received 1000 mg vitamin C (as two 500 mg tablets) once daily for three months. Although blood pressure decreased in both groups, the systolic blood pressure in patients given vitamin C was less (126.4 ± 7.47) compared to the other group (130.9 ± 7.27). A decrease in malondialdehyde, an increase in erythrocyte sodium-potassium adenosine triphosphatase (Na+ K+ ATPase) and an increase in the superoxide dismutase levels were observed in both groups. The increase in SOD was statistically more in the patients given vitamin C in addition to amlodipine (0.1717 ± 0.0150 compared to 0.152 ± 0.0219 units/100 ml assay). In spite of the known antihypertensive, antioxidant activity, similarity in correcting endothelial dysfunction independently, giving the two drugs together and early introduction of vitamin C perhaps decreases oxidative stress and augments the antioxidant status. This may prevent further vascular damage due to oxidative stress, leading to a better prognosis in essential hypertension patients. PMID:18188416

    The ambulatory arterial stiffness index (AASI) is a marker of arterial stiffness and is derived from ambulatory 24-h blood pressure registration. We studied whether the AASI could be used as a predictive factor for the presence of renal artery stenosis (RAS) in patients with a suspicion of secondary hypertension and as such as a diagnostic tool for RAS. We included 169 patients with difficult-to-treat hypertension. They all underwent 24-h ambulatory blood pressure monitoring registration, imaging of the renal arteries, and cardiovascular risk measurement, including smoking, history, biometrics, blood pressure, renal function, lipids, and glucose metabolism. Performing univariate and multivariate analyses, we investigated if AASI and the other cardiovascular risk factors were related to the presence of RAS. Of the 169 patients (49% women), 31% had RAS. The mean AASI was 0.44 (0.16). The presence of RAS showed no significant correlation with AASI (r = 0.14, P = 0.06). Age (r = 0.19, P = 0.01), hypercholesterolemia (r = 0.26, P = 0.001), history of CVD (r = 0.22, P = 0.004), and creatinine clearance (r = −0.34, P < 0.001) all demonstrated a correlation with RAS. Although AASI is higher in patients with RAS, AASI does not independently predict the presence of RAS in hypertensive subjects. PMID:28018907

    ABSTRACT Proteinuria in hypertension is an early marker of renal disease and a predictor for the progression of end stage renal disease, and cardiovascular diseases. This study was designed to determine the prevalence of proteinuria and its association with cardiovascular risk factors among adult hypertensive patients in Afghanistan. Five hundred fifty-five patients with a high blood pressure recorded in an outpatient clinic in Andkhoy, Afghanistan from December 2014 to May 2015, were included in this study. Data obtained from each patient, included demographic characteristics, body mass index, blood pressure patterns, cardiovascular history, cardiovascular risk factors, comorbidity, and current drug-therapy. Dipstick screening for proteinuria was performed with reagent test strips. The mean age of the patients was 57.9 ± 13.3 years, and a female predominance was observed (n = 333, 60%). The prevalence of proteinuria was 67.2%. The predictors of proteinuria were found to be age ≥65 years (odds ratio [OR] 1.02, 95% confidence interval [CI] 1.00–1.04), smoking (OR 1.88, 95% CI 1.17–3.02), heart failure (OR 2.23, 95% CI 1.13–4.41), and diabetes mellitus (OR 3.41, 95% CI 1.49–7.81). In conclusion, this study shows that proteinuria is highly prevalent among hypertensive outpatients in an outpatient clinic in Andkhoy, Afghanistan, especially in those with high cardiovascular risk.

    Background and Objectives In clinical trials, hypertensive patients tend to have higher interleukin-18 (IL-18) concentrations than normotensive groups, but the relationship between IL-18 and left ventricular hypertrophy (LVH), which is a marker of end-organ damage, is not well studied. We aimed to investigate the relationship between IL-18 and LVH in apparently healthy subjects free of clinically significant atherosclerotic disease. Subjects and Methods We enrolled 198 subjects (102 women and 96 men) between May 2006 and March 2007, who were free of cardiovascular or immune diseases, but were suspected to have hypertension. Twenty-four-hour ambulatory blood pressure monitoring and two-dimensional echocardiography were performed. Lipid profiles, high-sensitivity CRP (hs-CRP), IL-18, and whole blood cell counts were measured for all subjects. Results White blood cell count, hs-CRP, left ventricular mass, left ventricular mass index (LVMI), and IL-18 were higher in the hypertensive group than in the normotensive group (p=0.045, p=0.004, p<0.0001, p=0.001, and p=0.017 respectively). Twenty-four hour day and night systolic and diastolic blood pressure averages were positively correlated with IL-18 level in the entire study population. In multivariate regression analysis, left ventricular mass index and hs-CRP level were independently associated with IL-18 level in both the hypertensive group and the entire study population (β=0.154, β=0.149 p=0.033, p=0.040 and β=0.151, β=0.155 p=0.036, p=0.032 respectively) Conclusion We found that IL-18 level independently predicted LVMI in both the general population and in newly diagnosed hypertensive patients.

    In patients with chronic diseases, expectations of care are associated with clinical outcomes. Using open-ended interviews, we elicited the expectations of treatment in 93 hypertensive African-American patients. During routine clinic visits, patients were asked, "What are your expectations of the treatment your doctor prescribed for your high blood pressure?" Their responses were explored with the probes: Do you expect to take your blood pressure medications for the rest of your life? Do you expect to take your medications daily regardless of symptoms? Do you expect a cure for your high blood pressure? Using standard qualitative techniques, patients' responses were grouped into a taxonomy of three categories of expectations reflecting patients' role, physicians' role, and medication effects. They expected to take active role in their treatment, especially as it relates to adoption of healthy behaviors. They expected their physicians to educate them about blood pressure treatment, and they expected medications to lower their blood pressure and prevent heart attack, stroke, and kidney failure. Despite such appropriate expectations, a considerable proportion of patients had nonbiomedical expectations of their treatment-38% expected a cure, 38% did not expect to take their medications for life and 23% take medications only with symptoms. The taxonomy of patient expectations outlined in this study may serve as a useful framework for patient education and counseling about hypertension and its management in this patient population.

    Renal denervation can reduce blood pressure in certain patients with resistant hypertension. The effect in patients with isolated systolic hypertension (ISH, ≥140/<90 mm Hg) is unknown. This study investigated the effects of renal denervation in 126 patients divided into 63 patients with ISH and 63 patients with combined hypertension (CH, ≥140/≥90 mm Hg) defined as baseline office systolic blood pressure (SBP) ≥140 mm Hg despite treatment with ≥3 antihypertensive agents. Renal denervation significantly reduced office SBP and diastolic blood pressure (DBP) at 3, 6, and 12 months by 17/18/17 and 5/4/4 mm Hg in ISH and by 28/27/30 and 13/16/18 mm Hg in CH, respectively. The reduction in SBP and DBP in ISH was lower compared with patients with CH at all observed time points (P<0.05 for SBP/DBP intergroup comparison). The nonresponder rate (change in office SBP <10 mm Hg) after 6 months was 37% in ISH and 21% in CH (P<0.001). Mean 24-hour ambulatory SBP and DBP after 3, 6, and 12 months were significantly reduced by 10/13/15 and 6/6/9 mm Hg in CH, respectively. In patients with ISH the reduction in systolic ambulatory blood pressure was 4/8/7 mm Hg (P=0.032/P<0.001/P=0.009) and 3/4/2 mm Hg (P=0.08/P<0.001/P=0.130) in diastolic ambulatory blood pressure after 3, 6, and 12 months, respectively. The ambulatory blood pressure reduction was significantly lower after 3 and 12 months in SBP and after 12 months in ambulatory DBP, respectively. In conclusion, renal denervation reduces office and ambulatory blood pressure in patients with ISH. However, this reduction is less pronounced compared with patients with CH.

    Background Among Kazakh-Chinese population in Xinjiang province of China, prevalence of obesity and hypertension were 40.1% and 50.3% respectively, the highest across all ethnic groups residing in this pastureland. Despite this, there remained a dearth of information regarding the association between the anthropometric measures [body mass index (BMI), waist circumference (WC), waist-hip ratio (WHR), Waist-to-height ratio (WHtR) etc.] and indicators for hypertension control [achieved levels of systolic and diastolic blood pressures (SBP and DBP), pulse pressure index (PPI), ankle-brachial index (ABI) etc.] among them. Method A cross-sectional study was conducted in Xinjiang to determine the distribution and inter-relationships of the anthropometric measures and indicators for achieved BP control as well as their predictors among hypertension patients of Kazakh-Chinese ethnicity. Out of 550 randomly selected patients, 516 completed the interview, anthropometry and BP assessments. Results In the sample population, average SBP, DBP and PP were 156.26±24.40mmHg, 87.55±14.73mmHg and 68.71±19.39mmHg respectively. Bivariate analysis identified age, gender, education, duration of hypertension, WC and BMI being factors influencing the achieved levels of BP. Adjusted multiple linear regression models elicited positive associations of age (βa = 0.152, p = 0.001) and duration of hypertension (βa = 0.132, p = 0.003) with achieved level of SBP as well as BMI (βa = 0.135, p = 0.002) with DBP. Age (βa = 0.207, p<0.001) and WHtR (βa = 0.304, p = 0.005) were positively and WC (βa = -0.406, p<0.001) was negatively associated with PPI. Increasing age (βa = -0.125, p = 0.005), female gender (βa = -0.122, p = 0.005) and 5years’ duration of hypertension (βa = -0.091, p<0.039) were negatively associated with ABI. After adjustment for socio-demographic variables, hypertensive patients with (reference = without) abdominal obesity had 93% (p = 0.013) higher odds of missing the

    We reviewed the Chinese and English literature for the efficacy and safety data of valsartan monotherapy or combination therapy in Chinese hypertensive patients. According to the data of ten randomized controlled trials, valsartan monotherapy was as efficacious as another angiotensin receptor blocker or other classes of antihypertensive drugs, excepting the slightly inferior diastolic blood pressure-lowering effect in comparison with calcium channel blockers. According to the data of six randomized controlled trials, valsartan combination, with hydrochlorothiazide, amlodipine, or nifedipine gastrointestinal therapeutic system, was more efficacious than monotherapy of valsartan, amlodipine, or nifedipine gastrointestinal therapeutic system. According to these trials, valsartan had an acceptable tolerability, regardless of whether it was used as monotherapy or in combination therapy. Nonetheless, several rare side effects have been reported, indicating that it should still be used with caution. This is of particular importance given that there are millions of hypertensive patients, worldwide, currently exposed to the drug. PMID:24403822

    The therapeutic decision should be a collaboration between us the doctor and the patient. Patients have different tolerance and education levels, ranging from the highly cautious to the careless one. Treatment initiation in glaucoma is based on intraocular pressure levels, age, race, life expectancy, family history, progression risk, associated pathology. The therapeutic effort is aiming to maintain both quality of life and sight, through sustainable costs. Now we have the proof that intraocular pressure is just another risk factor among many others, lowering-pressure treatment being able to reduce the individual risk of progression. Still, only the high-risk ocular hypertension will be treated, considering other risk factors. There is a fine line between early glaucoma and ocular hypertension, the therapeutic decision and monitoring algorithm varying with the individual risk of progression.

    ABSTRACT OBJECTIVE To verify the effects of antihypertensive treatment (pharmacological and non-pharmacological) on the health-related quality of life of individuals with hypertension. METHODS We conducted a systematic review with meta-analysis using the following databases: IBECS, LILACS, SciELO, Medline, Cochrane, Science Direct, Scopus and the Brazilian Capes Theses and Dissertations Database. The statistical analysis was performed using Review Manager, version 5.2. The average difference was used for the summarization of meta-analytic effect by the fixed-effect model. Twenty studies were included. RESULTS The summarization of the effect showed an average increase of 2.45 points (95%CI 1.02–3.87; p < 0.0008) in the quality of life of individuals adhering to non-pharmacological treatment for arterial hypertension. Adherence to pharmacological treatment indicated an average increase of 9.24 points (95%CI 8.16–10.33; p < 0.00001) in the quality of life of individuals with arterial hypertension. CONCLUSIONS Non-pharmacological treatment improves the overall quality of life and physical domain of people with arterial hypertension. Adherence to pharmacological treatment has a positive impact on the mental and physical domains of patients, as it did on the overall quality of life score. PMID:28099657

    It has been reported that the number of circulating endothelial progenitor cells (EPCs) reflects the endogenous vascular repair ability, with the EPCs pool declining in the presence of cardiovascular risk factors. However, their relationship with hypertension and the effects of anti-hypertensive treatment remain unclear. We randomized 29 patients with mild essential hypertension to receive barnidipine up to 20 mg or hydrochlorothiazide (HCT) up to 25 mg. Circulating EPCs were isolated from peripheral blood at baseline and after 3 and 6 months of treatment. Mononuclear cells were cultured with endothelial basal medium supplemented with EGM SingleQuots. EPCs were identified by positive double staining for both FITC-labeled Ulex europaeus agglutinin I and Dil-labeled acethylated low-density lipoprotein. After 3 and 6 months of treatment, systolic and diastolic blood pressure (BP) were significantly reduced. No difference was observed between drugs. An increase in the number of EPCs was observed after 3 and 6 months of anti-hypertensive treatment (p < 0.05). Barnidipine significantly increased EPCs after 3 and 6 months of treatment, whereas no effect was observed with HCT. No statistically significant correlation was observed between EPCs and clinical BP values. Our data suggest that antihypertensive treatment may increase the number of EPCs. However, we observed a different effect of barnidipine and HCT on EPCs, suggesting that, beyond its BP lowering effect, barnidipine may elicit additional beneficial properties, related to a healthier vasculature.

    Introduction Erythropoietin (EPO) is a commonly used option in the treatment of chemotherapy-induced anaemia (CIA). However, ∼30–50% of patients fail to achieve an adequate response after initial treatment. Prior studies have demonstrated that intravenous iron might synergistically improve therapeutic response to EPO treatment in this patient population. Methods and analysis We will perform this multicentre, randomised, open-label, parallel-group, active controlled non-inferiority study to compare the two combination therapies of EPO plus intravenous iron regimen versus doubling the dose of EPO in patients with CIA who have an inadequate response to initial EPO treatment at a routine dose. A total of 603 patients with an increase in haemoglobin (Hb) <1 g/dL will be enrolled and randomised to one of the three study treatment groups at a 1:1:1 ratio Group 1: EPO treatment at the original dose plus intravenous iron dextran 200 mg every 3 weeks (Q3W) for 15 weeks; Group 2: EPO treatment at the original dose plus intravenous iron dextran 100 mg, twice a week for 5 weeks; Group 3: the control group, doubling the EPO dose without preplanned iron supplementation. The primary outcome measure to compare is the Hb response rate at week 15 and the secondary end points involve therapeutic blood transfusions. Time-to-progression, adverse events and quality of life will also be evaluated. Ethics and dissemination All participants will provide informed consent; the study protocol has been approved by the independent ethics committee of Shanghai East Hospital. This study would clearly demonstrate the potential benefit of combining epoetin treatment with intravenous iron supplementation. Findings will be shared with participating hospitals, policymakers and the academic community to promote the clinical management of CIA in China. Trial registration number NCT02731378. PMID:27855097

    Purpose To report a rare case of idiopathic intracranial hypertension (IIH) in a prepubertal pediatric patient. Case Report The patient was an 11-year-old Japanese boy. Initially, an ophthalmologist found severe papilledema, and the patient was diagnosed with IIH. He was unresponsive to conservative therapy, and a ventriculoperitoneal shunt was inserted in the Neurosurgery Department because the visual impairment was severe. Twelve months after the shunt, the improvement in vision was limited due to optic disc atrophy. Conclusion Ophthalmologists need to be more aware of II, especially in cases with severe papilledema that can lead to permanent reduction of vision. PMID:27065853

    We describe a patient with severe pulmonary arterial hypertension scheduled to undergo live-related renal transplantation. We emphasise on meticulous anaesthetic management and early renal transplantation to prevent the progression of disease which would become refractory to treatment, leading to right ventricular failure. Regional (continuous epidural) anaesthesia has been used as technique of choice, where the selective advantages of this technique have been put to good use. PMID:28250487

    Background The rate of blood pressure control among hypertensive patients is poor and the reasons for poor control of blood pressure remain poorly understood globally. Objective To assess the rate of blood pressure control among adult hypertensive patients at Jimma University Specialized Hospital. Materials and Methods We conducted a hospital based cross sectional study among adult hypertensive patients at Jimma University Specialized Hospital hypertension clinic from March 4, 2015 to April 3, 2015. Data on sociodemographic characteristics of the participants and adherence to antihypertensive medication(s) were collected from patients by face to face interview using a pretested structured questionnaire. Comorbidities, antihypertensive medication(s) and blood pressure measurements were collected retrospectively from medical records. Medication adherence was assessed using Morisky’s Medication Adherence Scale-8 score. We did the statistical analysis using chi-square test and binary logistic regression with level of α set at 0.05. Statistical significance was considered for variables with p<0.05. Results Out of 311 participants, 286 patients were eligible and were studied. More than half, 154 (53.8%), of the participants were males. The mean age of the participants was 54.8± 12.6 years (range 26 to 94). The majority, 196 (68.53%), of the participants were taking more than one antihypertensive medication. More than one third (39.5%) of the participants were non adherent to their medication(s). The rate of blood pressure control was 50.3%. In a univariate logistic regression analyses, age ≥65 years old (P = 0.008), physical inactivity (p<0.001), chat chewing (P<0.001), adding salt to food (P<0.001), and coffee use (P<0.001) are significantly associated with uncontrolled blood pressure Conclusion Almost half of the hypertensive patients on follow up had uncontrolled blood pressure. We recommend better health education and care of patients to improve the rate of

    Hypertension affects about 10 – 25% of the population and is an important risk factor for cardiovascular and renal disease. The renin-angiotensin system is frequently implicated in the pathophysiology of hypertension, be it primary or secondary. The prevalence of primary aldosteronism increases with the severity of hypertension, from 2% in patients with grade 1 hypertension to 20% among resistant hypertensives. Mineralcorticoid hypertension includes a spectrum of disorders ranging from renin-producing pathologies (renin-secreting tumors, malignant hypertension, coarctation of aorta), aldosterone-producing pathologies (primary aldosteronism – Conns syndrome, familial hyperaldosteronism 1, 2, and 3), non-aldosterone mineralocorticoid producing pathologies (apparent mineralocorticoid excess syndrome, Liddle syndrome, deoxycorticosterone-secreting tumors, ectopic adrenocorticotropic hormones (ACTH) syndrome, congenitalvadrenal hyperplasia), and drugs with mineraocorticoid activity (locorice, carbenoxole therapy) to glucocorticoid receptor resistance syndromes. Clinical presentation includes hypertension with varying severity, hypokalemia, and alkalosis. Ratio of plasma aldosterone concentraion to plasma renin activity remains the best screening tool. Bilateral adrenal venous sampling is the best diagnostic test coupled with a CT scan. Treatment is either surgical (adrenelectomy) for unilateral adrenal disease versus medical therapy for idiopathic, ambiguous, or bilateral disease. Medical therapy focuses on blood pressure control and correction of hypokalemia using a combination of anti-hypertensives (calcium channel blockers, angiotensin converting enzyme inhibitors, or angiotensin receptor blockers) and potassium-raising therapies (mineralcorticoid receptor antagonist or potassium sparing diuretics). Direct aldosterone synthetase antagonists represent a promising future therapy. PMID:22145132

    Chronic thromboembolic pulmonary hypertension (CTEPH) is an ominous disease leading to progressive right heart failure. Selected patients can be treated by pulmonary endarterectomy (PEA). We assessed long-term clinical outcome of patients with CTEPH who underwent PEA and patients who remained on medical treatment alone. A total of 112 consecutive patients with CTEPH referred between 1998 and 2008 to one center were followed for a mean of 35 (range 0-128) months after diagnosis. All the patients had advanced pulmonary hypertension at baseline. The operated group had higher World Health Organization functional class compared to the nonoperated group. No other differences in hemodynamic, echocardiographic, or biochemical parameters were observed at baseline. Despite the perioperative mortality rate of 9.1%, patients who underwent PEA had significantly lower long-term mortality compared to nonoperated patients (12.7% vs 34.8%; P = .003), and PEA survivors showed sustained clinical improvement. All efforts should be undertaken to perform PEA in all patients with operable CTEPH.

    To investigate the significance of the electrocardiographic (ECG) pattern of left ventricular hypertrophy and strain, two groups of asymptomatic patients with essential hypertension were compared. The patients were similar in terms of age, smoking habit, serum cholesterol and blood pressure levels, but differed in the presence (Group I, n = 23) or absence (Group II, n = 23) of the ECG pattern of left ventricular hypertrophy and strain. Group I patients had significantly more episodes of exercise-induced ST segment depression (14 versus 4, p less than 0.05) and reversible thallium perfusion abnormalities (11 of 23 versus 3 of 23, p less than 0.05) despite similar exercise capacity and absence of chest pain. Nonsustained ventricular tachycardia was detected on 24 h ambulatory ECG monitoring in two patients in Group I, but no patient in Group II. Coronary arteriography performed in 20 Group I patients demonstrated significant coronary artery disease in 8 patients. This study has shown that there is a subgroup of hypertensive patients with ECG left ventricular hypertrophy and strain who have covert coronary artery disease. This can be detected by thallium perfusion scintigraphy, and may contribute to the increased risk known to be associated with this ECG abnormality.

    AIM To determine the outcomes of partial splenic embolization (PSE) for massive splenomegaly due to idiopathic portal hypertension (IPH). METHODS In this prospective study, we evaluated the characteristics and prognosis of consecutive patients with IPH who underwent PSE for all indications at a single medical center between June 2009 and January 2015. The inclusion criteria were: presence of hypersplenism, massive splenomegaly, and resultant pancytopenia. The exclusion criteria were: presence of other diseases causing portal hypertension. During the post-PSE period, the patients were hospitalized. All patients underwent abdominal computed tomography imaging 4 wk post-PSE to determine total splenic and non-infarcted splenic volumes. RESULTS A total of 11 patients, with median age of 33.27 ± 4.8 years, were included in the study. Mean spleen size was 22.9 cm (21-28 cm), and severe hypersplenism was diagnosed in all patients before PSE. Post-PSE, leukocyte and platelet counts increased significantly, reaching peak levels in the second week with gradual decreases thereafter. Liver function tests did not exhibit significant changes during post-intervention follow-up. All patients developed post-embolization syndrome, and one patient experienced serious complications; all complications were successfully treated with conservative therapy and no death occurred. CONCLUSION Our findings showed that PSE has a lower complication rate than previously-reported surgical complication rates, which supports this intervention as a viable alternative for high-risk operable patients with severe hypersplenism.

  15. Treatment of gastropathy and gastric antral vascular ectasia in patients with portal hypertension.

    Portal hypertensive gastropathy (PHG) and gastric antral vascular ectasia (GAVE) are two distinct gastric mucosal lesions that may cause acute and/or chronic upper gastrointestinal hemorrhage in patients with cirrhosis. Whereas PHG is associated with portal hypertension, GAVE may present in patients without portal hypertension or liver disease. Diagnosis is made upon visualization of the characteristic lesions with upper gastrointestinal endoscopy, although the differential may be difficult at times. PHG is characterized endoscopically by a mosaic pattern with or without red signs and a proximal distribution. PHG mainly causes chronic blood loss and anemia in patients with cirrhosis but also can cause acute hemorrhage. First-line therapy for chronic hemorrhage from PHG is a nonselective beta-blocker (propranolol or nadolol) and iron supplementation. If bleeding/anemia are not controlled with these measures and the patient is transfusion-dependent, shunt therapy (transjugular intrahepatic portosystemic shunt or shunt surgery) should be considered. Management of acute bleeding from PHG, an infrequent event, should be accomplished with a vasoactive drug, somatostatin (or its analogues) or terlipressin. If bleeding responds, the patient must be switched to a nonselective beta-blocker. Shunt therapy should be considered in patients who rebleed or continue to bleed despite adequate beta-blocker therapy. GAVE is less common than PHG. It is characterized by red spots without a background mosaic pattern, typically in the gastric antrum. When lesions have a linear distribution, the lesion is called "watermelon stomach." GAVE is a cause of chronic gastrointestinal bleeding and anemia in patients with cirrhosis. If lesions are localized, first-line therapy is argon plasma coagulation. In more diffuse lesions, therapy with argon plasma coagulation is more complicated. Preliminary data suggest that cryotherapy may be a reasonable option for diffuse GAVE lesions. Neither beta

    Epidemiological evidence suggests that circulating 25-hydroxyvitamin D (25OHD) levels are inversely associated with hemoglobin (Hb) levels and anemia risk. We evaluated whether vitamin D supplementation improves Hb levels and reduces anemia risk in hypertensive patients. Two hundred patients with 25OHD levels <75 nmol/L who attended the Styrian Vitamin D Hypertension Trial were included, of whom 188 completed the trial. Patients randomly received 2800 IU vitamin D3 daily or a matching placebo for eight weeks. Initially, the prevalence of anemic status (Hb levels <12.5 g/dL) and deficient 25OHD levels (<30 nmol/L) was 6.5% and 7.5%, respectively. All anemic patients had 25OHD levels >50 nmol/L. The mean (95% confidence interval) vitamin D effect on Hb levels was 0.04 (−0.14 to 0.22) g/dL (P = 0.661). Moreover, vitamin D treatment did not influence anemic status significantly (P > 0.999). Likewise, vitamin D had no significant effect on Hb levels in the subgroups of anemic patients or in patients with initial 25OHD levels <30 nmol/L. In conclusion, a daily vitamin D supplement of 2800 IU for eight weeks did not improve Hb levels or anemic status in hypertensive patients. Future trials should focus on anemic patients with deficient 25OHD levels (e.g., <30 nmol/L). This trial is registered with clinicaltrials.gov [NCT02136771]. PMID:27006655

    Background: Endothelial dysfunction may be involved in the pathophysiology of cardiac abnormalities in patients with diabetes mellitus (DM). A correlation between endothelial dysfunction and diastolic dysfunction in patients with type 1 DM has been demonstrated, but this relationship has not been well investigated in type 2 DM. Objective: Compare groups of patients with type 2 DM and hypertension with and without diastolic dysfunction using endothelial function indexes, and to assess whether correlations exist between the diastolic function and the endothelial function indexes. Method: This was a cross-sectional study of 34 men and women with type 2 DM and hypertension who were aged between 40 and 70 years and were categorized based on assessments of their Doppler echocardiographic parameters as having normal (14 patients) and abnormal (20 patients) diastolic function. Flow-mediated dilatation (FMD) assessments of the brachial artery evaluated the patients’ endothelial function. Results: The mean maximum FMD was 7.15 ± 2.80% for the patients with diastolic dysfunction and it was 11.85 ± 4.77% for the patients with normal diastolic function (p = 0.004). Correlations existed between the maximum FMD and the E/e' ratio (p = 0.040, r = -0.354) and the early wave velocity (e') at the lateral mitral annulus (p = 0.002, r = 0.509). Conclusion: The endothelial function assessed by FMD was worse in hypertensive diabetic patients with diastolic dysfunction. There were correlations between the diastolic function indexes and the endothelial function indexes in our sample. PMID:27867429

    Background Inhaled treprostinil is a prostacyclin analog approved for the treatment of pulmonary arterial hypertension (PAH) that may provide a more convenient treatment option for patients receiving inhaled iloprost while maintaining the clinical benefit of inhaled prostacyclin therapy. Aims In this open-label safety study, 73 PAH patients were enrolled with primarily World Health Organization Class II (56%) or III (42%) symptoms. At baseline, most patients (93%) were receiving 5 μg of iloprost per dose but 38% of patients reported a dosing frequency below the labeled rate of 6–9 times daily. Patients initiated inhaled treprostinil at 3 breaths four times daily (qid) at the immediate next scheduled iloprost dose. The primary objective was to assess the safety of rapid transition from iloprost to inhaled treprostinil; clinical status and quality of life were also assessed. Results Most patients (84%) achieved the target treprostinil dose of 9 breaths qid and remained on study until transition to commercial therapy (89%). The most frequent adverse events (AEs) were cough (74%), headache (44%), and nausea (30%), and five patients prematurely discontinued study drug due to AE (n = 3), disease progression (n = 1), or death (n = 1). At week 12, the time spent on daily treatment activities was reduced compared to baseline, with a mean total savings of 1.4 h per day. Improvements were also observed at week 12 for 6-min walk distance (+16.0; P < 0.001), N-terminal pro-B-type natriuretic peptide (−74 pg/mL; P = 0.001), and the Cambridge Pulmonary Hypertension Outcome Review (all domains P < 0.001). Conclusions Pulmonary arterial hypertension patients can be safely transitioned from inhaled iloprost to inhaled treprostinil while maintaining clinical status. PMID:22970909

    OBJECTIVES: The primary purpose of this study was to determine the tolerability of intermittent intravenous (IV) sildenafil for the treatment of pulmonary hypertension in pediatric patients. Secondary objectives were to evaluate parameters related to efficacy. METHODS: This was a retrospective chart review from January 2013 to August 2014 of pediatric patients under age 18 years treated with intermittent doses of IV sildenafil for pulmonary hypertension. Patients were excluded if they were over age 18 years or received sildenafil for other indications. Measures collected to assess tolerability include blood pressure and heart rate before and after the administration of IV sildenafil, as well as adverse events. RESULTS: Thirty-seven patients (21 females and 16 males) were identified meeting inclusion criteria, and 21 (56.8%) were on oral sildenafil prior to the initial IV dose. The mean decrease in blood pressure after the first dose of IV sildenafil was 7.16/2.74 mmHg. The decrease in systolic blood pressure was statistically significant. During the study period, 5 patients experienced medication related adverse events, primarily hypotension. Despite this, none of the patients had the medication discontinued due to these events. For secondary objectives, a statistically significant difference was not found between other clinical measures before and after intermittent IV sildenafil dosing. CONCLUSIONS: Sildenafil, when administered as intermittent IV doses, was tolerated by the majority of patients evaluated in this study. For pediatric patients with pulmonary hypertension in whom enteral or continuous IV sildenafil cannot be administered, intermittent IV sildenafil may be considered as an alternative administration option.

    This study was conducted to determine the effects of a tablet combining losartan/hydrochlorothiazide (L/HCTZ) in comparison with losartan alone in Japanese diabetic patients with hypertension. Thirty consecutive Japanese diabetic patients with hypertension were randomly assigned to group A, receiving losartan alone for the first 3 months, then L/HCTZ for the next 3 months, or group B, receiving L/HCTZ for the first 3 months, then losartan alone for the next 3 months. Clinical and biological parameters were obtained before, and 3 and 6 months after the start of this study. The decreases in systolic and diastolic blood pressure (BP) during treatment with L/HCTZ were significantly greater than in treatment with losartan alone. Both treatments significantly and similarly decreased urinary albumin excretion, the cardio-ankle vascular index (CAVI) and augmentation index (AI). There was no significant difference in metabolic change during both the mono- and combination pharmacotherapies. The tablet combining L/HCTZ significantly reduced systolic and diastolic BP compared with the losartan monotherapy, and offered benefits similar to losartan monotherapy for albuminuria, arterial stiffness assessed by the CAVI and AI, and metabolic effects. Thus, the L/HCTZ tablet could be a useful drug for Japanese diabetic patients with hypertension.

    Nutrition is a dominant peripheral factor in increasing blood pressure; however, little information is available about the nutritional status of hypertensive patients in Iran. This study aimed to compare nutritional behaviors of the rural controlled and uncontrolled hypertensive patients and to determine the predictive power of nutritional behaviors from blood pressure. This cross-sectional study was conducted on 671 rural hypertensive patients, using multistage random sampling method in Ardabil city in 2013. Data were collected by a 3-day food record questionnaire. Nutritional data were extracted by Nutritionist 4 software and analyzed by the SPSS 18 software using Pearson correlation, multiple linear regression, ANOVA, and independent t-test. A significant difference was observed in the means of fat intake, cholesterol, saturated fat, sodium, energy, calcium, vitamin C, fiber, and nutritional knowledge between controlled and uncontrolled groups. In the controlled group, sodium, saturated fats, vitamin C, calcium, and energy intake explained 30.6% of the variations in blood pressure and, in the uncontrolled group, sodium, carbohydrate, fiber intake, and nutritional knowledge explained 83% of the variations in blood pressure. There was a significant difference in the nutritional behavior between the two groups and changes in blood pressure could be explained significantly by nutritional behaviors. PMID:27516908

    Background Vascular dysfunction is highly prevalent if not ubiquitous in patients with hypertension. We compared two different measures of vascular function obtained from digital volume waveforms with measures of ventricular-vascular load derived from 24-hour blood pressure (BP) recordings in patients with hypertension. Methods Digital pulsatile volume waveforms were captured via plethysmography (peripheral arterial tone, PAT) and used to derive augmentation index (a measure of ventricular-vascular coupling) and the pulse wave amplitude-reactive hyperemia index (a measure of microvascular reactivity). Ambulatory arterial stiffness index (AASI) and the BP variability ratio (BPVR) were derived from 24-hour ambulatory BP recordings. Results There was a positive association between PAT-AIx and AASI (r = 0.52, P < 0.05). There was also a positive association between PAT-AIx and BPVR (r = 0.37, P < 0.05). PAT-AIx was not associated with PWA-RHI (r = -0.14, P > 0.05). PWA-RHI was not associated with AASI or BPVR (P > 0.05). Conclusions PAT-AIx is associated with ambulatory measures of vascular function and may offer clinical insight into vascular burden and cardiovascular disease risk in patients with hypertension independent of information obtained from PWA-RHI.

    The pathophysiological role of endothelial cells is important in the mechanism of progression of atherosclerosis and improvement of endothelial function may be important for cardiovascular morbidity. Calcium antagonists are reported to have protective effects on the endothelium in vitro and in vivo. In this clinical study, we investigated the effect of calcium antagonist, benidipine, on endothelial function in the patients with essential hypertension, which causes endothelial dysfunction. Twenty-five patients with hypertension without other risk factors for atherosclerosis were treated with monotherapy (8 mg benidipine, n=25) for 8 weeks. Blood pressure was reduced significantly. Endothelial function was evaluated using forearm blood flow by strain-gauge plethysmography after 8 weeks of treatment. Changes in vasodilator response to reactive hyperemia were significantly improved (p<0.01), while the response to nitroglycerin was not changed, suggesting the improvement of endothelial function. Moreover, we focused on hepatocyte growth factor (HGF), which is a novel angiogenic growth factor with an anti-apoptotic action on endothelial cells, and evaluated involvement of HGF in improvement of endothelial function. Serum HGF concentration in subjects treated with benidipine was significantly elevated at 8 weeks (p<0.05). Overall, these results demonstrated that benidipine improved endothelial dysfunction in patients with hypertension. Interestingly, an increase in serum HGF concentration by benidipine might contribute to the improvement of endothelial dysfunction.

    Background Treatment of end stage renal disease patients with short daily hemodialysis has been associated with an improvement in blood pressure. It is unclear from these studies if anti-hypertensive management had been optimized prior to starting short daily hemodialysis. Also, the potential mechanism(s) of blood pressure improvement remain to be fully elucidated. Study Design, Setting and Participants We undertook a randomized cross-over trial in adult hypertensive patients with ESRD treated with conventional hemodialysis to determine: 1) if short-daily hemodialysis is associated with a reduction in systolic blood pressure after a 3-month blood pressure optimization period and; 2) the potential mechanism(s) of blood pressure reduction. Blood pressure was measured using Canadian Hypertension Education Program guidelines. Extracellular fluid volume (ECFV) was assessed with bioimpedance. Serum catecholamines were used to assess the sympathetic nervous system. Interleukin-6 (IL-6) and thiobarbituric acid reactive substances (T-BARS) were used as markers of inflammation and oxidative stress respectively. Results After a 3-month run-in phase in which systolic blood pressure improved, there was no significant difference in pre-dialysis systolic pressure between short-daily and conventional hemodialysis (p = 0.39). However, similar blood pressures were achieved on fewer anti-hypertensive medications with short daily hemodialysis compared to conventional hemodialysis (p = 0.01). Short daily hemodialysis, compared to conventional hemodialysis, was not associated with a difference in dry weight or ECFV (p = 0.77). Sympathetic nervous system activity as assessed by plasma epinephrine (p = 1.0) and norepinephrine (p = 0.52) was also not different. Markers of inflammation (p = 0.42) and oxidative stress (p = 0.83) were also similar between the two treatment arms. Conclusions Patients treated with short daily, compared to conventional hemodialysis

    Hyperuricemia may promote the progression of hypertension and renal dysfunction. However, the effects of hyperuricemia treatment on blood pressure and renal function in adult hypertensive patients with hyperuricemia remain unclear. A total of 137 hypertensive patients with hyperuricemia (96 men and 41 women; mean age of 67 years) who recently started taking xanthine oxidase inhibitors (allopurinol or febuxostat) as outpatients were recruited. Serum uric acid level, estimated glomerular filtration rate (eGFR, ml min(-1) per 1.73 m(2)) and blood pressure (mm Hg) were retrospectively compared immediately before and shortly after starting treatment with xanthine oxidase inhibitors. The mean blood pressure and the eGFR immediately before starting treatment were 128/71 mm Hg and 44.6 ml min(-1) per 1.73 m(2), respectively. Although the eGFR decreased from 46.6 to 44.6 ml min(-1) per 1.73 m(2) before starting treatment with xanthine oxidase inhibitors, it increased to 46.2 ml min(-1) per 1.73 m(2) (P=0.001, compared with immediately before treatment) without any significant changes in blood pressure after the administration of xanthine oxidase inhibitors. Multiple regression analysis revealed that the increase in eGFR after starting xanthine oxidase inhibitor treatment positively correlated with the changes in systolic blood pressure and negatively correlated with the changes in uric acid levels and the use of renin-angiotensin system inhibitors. These results suggest that xanthine oxidase inhibitors may delay the progression of renal dysfunction in adult hypertensive patients with hyperuricemia.

This phenomenon called "non-dipping" (i.e. a lack of the normal nocturnal fall in blood pressure) is related to a higher incidence of end-organ damage such as left ventricular hypertrophy. It is the purpose of this study to evaluate, whether or not non-dipping of blood pressure may worsen the prognosis of hypertensive subjects. 116 consecutive hypertensives underwent an ambulatory blood pressure monitoring (ABPM) using the Spacelabs 2000 device. 2 groups were established: Group I (n = 87) were "dippers", group II (n = 29) "non-dippers" showing a diminished or even lack of nocturnal fall in blood pressure. No difference was seen concerning sex, mean 24-hour systolic blood pressure, systolic and diastolic causal blood pressure and heart rate. However, a significant difference in age and mean 24-hour diastolic blood pressure could be observed. In a follow-up investigation after approximately 31 months all patients and/or their physicians were contacted concerning cardiovascular events during the time since the ABPM was performed. In Group I only 1 transient ischemic attack occurred, but in group II 4 patients showed major cardiovascular events: 3 deaths occurred (2 of which caused by myocardial infarction, 1 by apoplexy), while 1 suffered from a transient ischemic attack (p < 0.001). Thus, in essential hypertension non-dipping of blood pressure is associated with an increased occurrence of cardiovascular events, and, therefore, the circadian blood pressure profile should be carefully monitored.

    Pulmonary hypertension is a common but often overlooked complication associated with thalassemia syndromes. There are limited data on the safety and efficacy of selective pulmonary vasodilators in this at-risk population. We, therefore, designed a 12-week, open-label, phase 1/2, pilot-scale, proof-of-principle trial of sildenafil therapy in 10 patients with β-thalassemia and at increased risk of pulmonary hypertension based on an elevated tricuspid regurgitant jet velocity >2.5 m/s on Doppler-echocardiography. Variables compared at baseline and after 12 weeks of sildenafil treatment included Doppler-echocardiographic parameters, 6-minute walked distance, Borg Dyspnea Score, New York Heart Association functional class, pulmonary function, and laboratory parameters. Treatment with sildenafil resulted in a significant decrease in tricuspid regurgitant jet velocity by 13.3% (3.0±0.7 versus 2.6±0.5 m/s, P=0.04), improved left ventricular end systolic/diastolic volume, and a trend towards a improved New York Heart Association functional class. No significant change in 6-minute walked distance was noted. Sildenafil was well tolerated, although minor expected adverse events were commonly reported. The total dose of sildenafil (mg) was strongly correlated with percent change in nitric oxide metabolite concentration in the plasma (ρ=0.80, P=0.01). There were also significant increases in plasma and erythrocyte arginine concentrations. Our study suggests that sildenafil is safe and may improve pulmonary hemodynamics in patients at risk of pulmonary hypertension; however, it was not demonstrated to improve the distance walked in 6 minutes. Clinical trials are needed to identify the best treatment strategy for pulmonary hypertension in patients with β-thalassemia. (clinicaltrials.gov identifier: NCT00872170).

    Microalbuminuria is an established early marker of endothelial dysfunction and damage. MicroRNAs (miRNAs) are emerging as essential modulators of cardiovascular physiology and disease. In the present study, we sought an association between the differential expression of related miRNAs in the peripheral blood mononuclear cells of untreated patients with newly diagnosed essential hypertension and the levels of urinary albumin excretion. We assessed the expression of the miRNAs miRNA-1, miRNA-133a, miRNA-26b, miRNA-208b, miRNA-499 and miRNA-21 in consecutive subjects with untreated newly diagnosed essential hypertension (aged 62.5±9.7 years) and with no indications of other organic heart disease. MiRNA expression levels in peripheral blood mononuclear cells were quantified by real-time reverse transcription-polymerase chain reaction. The prevalence of microalbuminuria was 9.8%. miRNA-208b and miRNA-133a were independently correlated with 24-h urinary albumin excretion. More specifically, a strong association was found between the gene expression levels of miRNA-208b in our patients' peripheral blood cells and urinary albumin (r=0.72, P<0.001). A similar association was found for miRNA-133a (r=0.372, P<0.001). In conclusion, miRNA-208b and miRNA-133a show distinct profiling in peripheral blood cells isolated from untreated patients with recently diagnosed essential hypertension. Their gene expression levels reveal a strong correlation with urinary albumin excretion levels. Our findings provide new perspectives on the development of a new generation of biomarkers for the better monitoring of end-organ damage in hypertension.

    Abstract Hypertension usually coexists with other chronic conditions and can cause disability in relation to activities of daily living. We examined the association between the number and categories of comorbid conditions and disability affecting activities of daily living in hypertension patients. The data were collected from the 2013 follow-up survey of the China Health and Retirement Longitudinal Study (CHARLS), which contains information about chronic conditions and disability. Additionally, socio-demographic characteristics of 3754 hypertension patients aged 45 and older were included in this study. Comorbid conditions included dyslipidemia, stroke, and 12 other chronic conditions. Disability in relation to activities of daily living was assessed using the basic activities of daily living (BADL) and the instrumental activities of daily living (IADL) instruments. Differences in BADL/IADL disability among patients with different comorbid conditions were compared using the chi-square test, and the influence of chronic conditions and socio-demographic characteristics on BADL/IADL disability was analyzed using logistic models. Without considering the influence of specific chronic conditions on BADL/IADL, hypertension patients with additional comorbid conditions were more likely to suffer from BADL/IADL disability. When considering the effect of specific chronic conditions, the number of comorbid conditions did not significantly influence BADL/IADL disability. Dyslipidemia, chronic lung disease, stroke, memory-related diseases, and arthritis/rheumatism were associated with BADL disability. Chronic lung diseases, heart diseases, stroke, stomach/digestive system diseases, emotional/nervous/psychiatric problems, memory-related diseases, arthritis/rheumatism, and asthma were associated with IADL disability. Additionally, female, people with lower education level, people living in village, and people living in middle and western China were more likely suffer from BADL

    The importance of number of tablets for patient compliance was investigated in 160 patients with mild-moderate essential hypertension treated with a beta-adrenoceptor blocker and a thiazide diuretic. Mean BP at entry 146 +/- 16/92 +/- 8 mm Hg. All patients were given pindolol 10 mg and clopamide 5 mg in one combination tablet or in separate tablets for 4 months respectively. Approximately 90% of the patients took greater than 90% of the prescribed dose throughout the study. Mean BP decreased progressively and heart rate increased slightly. Side effects were more frequently reported during the first month of the study than previously, and 30 patients discontinued the treatment. No differences in this respect were seen between 1 and 2 tablets daily. Approximately 75% of the patients preferred 1 tablet daily, but combining two drugs in one tablet had no effect upon compliance. PMID:6375710

    Background/Aims Intradialytic hypertension (IH) occurs frequently in some hemodialysis patients and increases mortality risk. We simultaneously compared pre-dialysis, post-dialysis and changes in extracellular volume and hemodynamics in recurrent IH patients and controls. Methods We performed a case-control study among prevalent hemodialysis patients with recurrent IH and hypertensive hemodialysis controls. We used bioimpedance spectroscopy and impedance cardiography to compare pre-dialysis, post-dialysis, and intradialytic change in total body water (TBW) and extracellular water (ECW), as well as cardiac index (CI) and total peripheral resistance index (TPRI). Results The ECW/TBW was 0.453 (0.05) pre-dialysis and 0.427 (0.04) post-dialysis in controls vs. 0.478 (0.03) and 0.461 (0.03) in IH patients (p=0.01 post-dialysis). The ECW/TBW change was −0.027 (0.03) in controls and −0.013 (0.02) in IH patients (p=0.1). In controls, pre- and post-dialysis TPRI were 3254 (994) and 2469 (529) dynes/sec/cm2/m2 vs. 2983 (747) and 3408 (980) dynes/sec/cm2/m2 in IH patients (p=0.002 post-dialysis). There were between-group differences in TPRI change (0=0.0001), but not CI (p=0.09). Conclusions Recurrent intradialytic hypertension is associated with higher post-dialysis extracellular volume and TPRI. Intradialytic TPRI surges account for the vasoconstrictive state post-dialysis, but intradialytic fluid shifts may contribute to post-hemodialysis volume expansion. PMID:27832647

    Baroreflex activation therapy (BAT) has been demonstrated to decrease office blood pressure (BP) in the randomized, double-blind Rheos trial. There are limited data on 24-hour BP changes measured by ambulatory BP measurements (ABPMs) using the first generation rheos BAT system suggesting a significant reduction but there are no information about the effect of the currently used, unilateral BAT neo device on ABPM. Patients treated with the BAT neo device for uncontrolled resistant hypertension were prospectively included into this study. ABPM was performed before BAT implantation and 6 months after initiation of BAT. A total of 51 patients were included into this study, 7 dropped out from analysis because of missing or insufficient follow-up. After 6 months, 24-hour ambulatory systolic (from 148 ± 17 mm Hg to 140 ± 23 mm Hg, P<0.01), diastolic (from 82 ± 13 mm Hg to 77 ± 15 mm Hg, P<0.01), day- and night-time systolic and diastolic BP (all P ≤ 0.01) significantly decreased while the number of prescribed antihypertensive classes could be reduced from 6.5 ± 1.5 to 6.0 ± 1.8 (P=0.03). Heart rate and pulse pressure remained unchanged. BAT was equally effective in reducing ambulatory BP in all subgroups of patients. This is the first study demonstrating a significant BP reduction in ABPM in patients undergoing chronically stimulation of the carotid sinus using the BAT neo device. About that BAT-reduced office BP and improved relevant aspects of ABPM, BAT might be considered as a new therapeutic option to reduce cardiovascular risk in patients with resistant hypertension. Randomized controlled trials are needed to evaluate BAT effects on ABPM in patients with resistant hypertension accurately.

    The relationship between adherence to antihypertension medications, treatment satisfaction and illness perception has not been studied so far. The primary objective of this study was to examine the association between adherence to medication, treatment satisfaction and illness perception in Lebanese hypertensive patients. The relation between medication adherence and blood pressure (BP) control was also assessed. In this cross-sectional study, patients were recruited from the physician's practice offices and community pharmacies in Beirut. Patients who had been treated for hypertension for at least 3 months were invited to participate in the study; they completed three questionnaires: the 8-item Morisky Medication Adherence Scale (MMAS-8), the Treatment Satisfaction Questionnaire for Medication (TSQM-4) and the Brief Illness Perception Questionnaire (BIPQ). BP was also measured and recorded. A total of 117 subjects were included, of whom 29.1% had poor adherence to their antihypertension treatment (MMAS-8 scores<6). The odds of having well-controlled hypertension was 3.5 times higher in patients with high adherence compared with patients with poor adherence (P=0.010). Treatment satisfaction was significantly greater in patients with good adherence (P<0.001). Neither socio-demographic, disease- nor drug-related characteristics of the participants were significantly associated with medication adherence. As for illness perception, even though the mean BIPQ score of adherent participants was lower than the mean score of non-adherent participants, this difference did not reach statistical significance. In conclusion, treatment satisfaction was found to be a predictor of adherence. Studies are needed to determine whether interventions to increase satisfaction can improve adherence and BP control.

    Chronic hepatitis caused by hepatitis B virus (HBV) is an endemic disease in India. It is associated with extrahepatic manifestations like polyarteritis nodosa (PAN) which is a vasculitis like disorder, presenting in subacute or chronic phase; involving visceral and systemic vessels. It should always be considered as a possible etiology of hypertension in an underlying setting of hepatitis B. We describe a 56-year-male patient with a history of chronic HBV who presented to the outpatient clinic with history of recent onset hypertension and suspected liver disease. Further work up for the cause of recent hypertension included a contrast computerized tomography of abdomen, which revealed concomitant pathologies of chronic liver disease and multiple aneurysms in bilateral kidneys. This case illustrates the unusual presentation of extrahepatic manifestation of viral hepatitis in the form of PAN of kidneys. PAN as an independent entity may be missed in specialized clinics evaluating liver pathologies, due to its insidious onset, atypical clinical symptoms and multi-systemic manifestations. The knowledge of extrahepatic, renal and vascular manifestations of hepatitis B unrelated to liver disease should be considered by physicians at the time of diagnosis and management of patients with HBV.

    Resistant hypertension is a common and refractory complication of hemodialysis (HD) patients and is associated with a higher risk of cardiovascular morbidity and mortality. Here we present a case of resistant hypertension treated successfully by nocturnal HD. A 63-year-old female with end-stage kidney disease was hospitalized for severe headache, objective vertigo and persistent vomiting for 1 month on February 6, 2012. She had been on intermittent HD for 3 months, and her blood pressure maintained 200-240/100-130 mm Hg even after using 7 kinds of antihypertensive drugs including olmesartan, benazepril, nitrendipine, arotinolol, terazosin, clonidine and torasemide. A CT of the abdomen revealed a mild hyperplasia of the left adrenal gland (fig. 1). However, plasma renin, angiotensin and aldosterone were all within the normal range. Nocturnal extended HD was initiated with a blood flow rate of 150 ml/min and a dialysis time of 7 h. After 3 months of nocturnal HD, all symptoms were relieved and her systolic blood pressure started to decrease by 10-20 mm Hg. Six months later, the predialysis blood pressure was decreased to 140-160/90-100 mm Hg and the antihypertensive drugs were reduced to 4 kinds. Meanwhile, the blood biochemical parameters including hemoglobin, serum calcium, phosphate and parathyroid hormone were all controlled well during 2 years of treatment. This case indicates that nocturnal extended HD is probably a promising and effective choice for resistant hypertension in HD patients.

    BACKGROUND Hypertension is a global public health crisis. Poorly controlled high blood pressure is one of the major factors contributed to this crisis. As lack of treatment adherence is often considered the main reason for this failure, the Treatment Adherence Questionnaire for Patient with Hypertension (TAQPH) was developed. Since this questionnaire should be reliable and strongly valid to be used in clinics and research, this study was performed to test the reliability and validity of the TAQPH. METHODS A cross-sectional study was conducted to validate the Persian version of TAQPH after using a modified forward/backward translation procedure. A total of 330 hypertensive patients were participated in this study. Construct and criterion validity, Cronbach¢s alpha, and test-retest reliability were used to validate the Persian scale. RESULTS Data analysis showed that the scale had excellent stability (intraclass correlation = 0.95) and good acceptability of internal consistency (α = 0.80). The exploratory factor analysis (EFA) was meaningful but was not confirmed with confirmatory factor analysis (CFA). The scale score was correlated with Morisky Medication Adherence Scale (MMAS) score (Ρ = 0.27). CONCLUSION In total, most of the psychometric properties of the 25-item P-TAQHP achieved the standard level and were sufficient to recommend for general use. PMID:27429627

    Effective reduction in blood pressure (BP) improves survival and morbidity in hypertensive patients. Combination therapy with multiple antihypertensive agents is frequently required in clinical practice and therapeutic trials to achieve target BP. Patients at elevated cardiovascular risk achieve the greatest benefit from equivalent reduction in BP and also require more stringent BP control. In patients with hypertension and diabetes mellitus or renal disease, BP control is of primary importance and blockade of the renin-angiotensin system (RAS) should be the initial therapeutic intervention. Choice of combination therapy has been insufficiently studied in major clinical cardiovascular endpoint trials. Diuretic therapy remains the logical addition to RAS blockade. Despite previous debate, the available evidence suggests long-acting calcium-channel blockers are also a safe and very effective addition to improve BP control further. The choice of antihypertensive combination therapy should not override the fundamental necessity of lowering BP to target levels.

    1 The pharmacokinetic properties of intravenous fenoldopam, a selective dopamine1-receptor agonist, were studied in 10 patients with essential hypertension. 2 Reduction in blood pressure was linearly related to the log fenoldopam plasma concentration (r = 0.69) and the log fenoldopam infusion rate (r = 0.71). 3 The mean elimination half-life (+/- s. e. mean) was 9.8 +/- 1.0 min. The total body clearance was 30.3 +/- 2.3 ml kg-1 min-1 and the volume of distribution was 582 +/- 62 ml kg-1. 4 The rapid onset of action, short elimination half-life, linear dose-response relationship, and ease of administration suggest that fenoldopam may have a role where parenteral treatment of hypertension is required.

    Hypertensive left ventricular hypertrophy can easily be diagnosed by echocardiography. It occurs in 30-50 per cent of hypertensive patients and has recently been shown to be a potent and independent predictor of morbidity and mortality, increasing the risk of sudden death, arrhythmia and severe coronary events. The condition usually presents as concentric left ventricular hypertrophy with symmetrically or asymmetrically thickened ventricular walls, but it may also be found with a dilated cavity. Its presence is a definite indication for active medical treatment. Guidelines for the choice of a particular antihypertensive drug are not yet available. Regression of the hypertrophy seems to be a rational goal of the treatment, but the beneficial effects of such a regression on left ventricular relaxation need further evaluation.

    2015-04-01

    The importance of regular physical activity in essential hypertension has been extensively investigated over the last decades and has emerged as a major modifiable factor contributing to optimal blood pressure control. Aerobic exercise exerts its beneficial effects on the cardiovascular system by promoting traditional cardiovascular risk factor regulation, as well as by favorably regulating sympathetic nervous system (SNS) activity, molecular effects, cardiac, and vascular function. Benefits of resistance exercise need further validation. On the other hand, acute exercise is now an established trigger of acute cardiac events. A number of possible pathophysiological links have been proposed, including SNS, vascular function, coagulation, fibrinolysis, and platelet function. In order to fully interpret this knowledge into clinical practice, we need to better understand the role of exercise intensity and duration in this pathophysiological cascade and in special populations. Further studies in hypertensive patients are also warranted in order to clarify the possibly favorable effect of antihypertensive treatment on exercise-induced effects.

    Background A reduction of dopaminergic (DAergic) activity with increased prolactin levels has been found in obese and hypertensive patients, suggesting its involvement as a pathophysiological mechanism promoting hypertension. Similarly, leptin action increasing sympathetic activity has been proposed to be involved in mechanisms of hypertension. The aim of this study was to analyze the effects of DA, norepinephrine (NE), and prolactin on leptin release and leptin gene (OB) expression in adipocytes from obese and hypertensive patients. Methods Leptin release and OB gene expression were analyzed in cultured adipocytes from 16 obese and hypertensive patients treated with DA (0.001, 0.01, 0.1, and 1.0 μmol/L), NE (1.0 μmol/L), insulin (0.1 μmol/L), and prolactin (1.0 μmol/L), and from five nonobese and normotensive controls treated with DA (1 μmol/L), NE (1 μmol/L), insulin (0.1 μmol/L), and prolactin (1.0 μmol/L). Results A dose-related reduction of leptin release and OB gene messenger ribonucleic acid expression under different doses of DA was observed in adipocytes from obese hypertensive patients. Whereas prolactin treatment elicited a significant increase of both leptin release and OB gene expression, NE reduced these parameters. Although similar effects of DA and NE were observed in adipocytes from controls, baseline values in controls were reduced to 20% of the value in adipocytes from obese hypertensive patients. Conclusion These results suggest that DAergic deficiency contributes to metabolic disorders linked to hyperleptinemia in obese and hypertensive patients. PMID:24348062

    Pulmonary arterial dissection is an extremely rare and usually lethal complication of chronic pulmonary hypertension. The condition usually manifests as cardiogenic shock or sudden death and is therefore typically diagnosed at postmortem examination rather than during life. However, recent isolated reports have described pulmonary artery dissection in surviving patients. The first case of pulmonary artery dissection in a surviving patient with cor pulmonale caused by chronic obstructive pulmonary disease is presented. The aetiology, pathophysiology, and clinical presentation of pulmonary artery dissection are reviewed and factors that may aid diagnosis during life are discussed.

    This study aimed at assessing the anthropometry, dietary intake and micronutrient status of hypertensive patients attending specialist hospitals in Ondo State, Nigeria. A descriptive case control study was conducted among subjects attending two specialist hospitals located in Akure and Ondo towns. A total of 452 subjects (44.9% males and 55.1% females), was purposely selected from the study centres. A structured questionnaire was designed to collect information on demographic characteristics, socio-economic parameters, nutrition knowledge and dietary intakes of the subjects. The quantities of subjects' dietary intakes were measured using household measurements. Weight, height, systolic (SBP) and diastolic (DBP) blood pressures were measured using electronic bathroom scale, standiometer and sphygmomanometer, respectively. The subject's urine was collected; and vitamin C, sodium, potassium, calcium, zinc and magnesium were determined using standard procedures. The results showed the following means: age 52.4 +/- 2.38 years, weight 66.4 +/- 1.63kg, height 1.64 +/- 0.01m, body mass index (BMI) 24.13 +/- 0.69kg/m2, SBP 124.86 +/- 2.3mmHg and DBP 76.22 +/- 1.86 mmHg. Blood pressure (BP) of the subjects showed that 46.9% had optimal BP, 14.2% normal BP, 11.5% high normal BP, 12.8% mild hypertension, 9.7% moderate hypertension and 4.9% severe hypertension. For BMI, 8.8% were underweight, 47.1% normal, 30.3% overweight, 6.0% obesity class I, 6.0% obesity class II and 1.8% obesity class III. The proportion of hypertensive subjects that were obese was significantly (P = 0.0001) higher than control subjects. Three-fifth of the control subjects had good nutrition knowledge compared to one-fifth of hypertensive subjects. The estimated mean energy intake was 8.46 MJ, protein 93.1g, carbohydrate 314.5g, fat 42.9g, fibres 5.6g and appreciable amount of vitamin C, calcium, zinc, magnesium, sodium and potassium. The subjects' urinary vitamin C concentration was 32.49 +/- 2.53mg

    The aim of this study was to determine changes in arterial pressure (AP) and heart rate (HR) during dental treatment under local infiltration anesthesia (LIA) in patients with controlled arterial hypertension (AHT) versus normotensive patients. A longitudinal comparative study involving repeated measurements in well-controlled hypertensive (cases) and normotensive patients (controls) was conducted. All patients received standardized preventive periodontal treatment under LIA (1.8 ml of 4% articaine with 1:100000 L-Adrenaline). AP and HR were determined at 5 different phases of treatment. The study comprised 82 patients, 46.3% of whom were hypertensive, 61% were female. Systolic (SAP) and diastolic (DAP) arterial pressure and HR increased as the procedure advanced and then returned to initial values in both groups. Average HR values were lower in normotensive than in hypertensive patients (p < 0.001). Significant differences in AP and HR were observed among initial, mid-procedure, and final values (p < 0.001). Both groups exhibited highest SAP values post-LIA administration (p < 0.01). Average HR was higher in normotensive than in hypertensive patients. The hypertensive patients tended to develop AHT (> 140/90 mmHg) more frequently throughout the procedure (p = 0.002), SHOWING a 4.93-fold higher risk. Logistic regression analysis showed that sex (p < 0.032) and AH (p < 0.007) were associated with a tendency to develop AHT during treatment. Controlled hypertensive patients with normal AP values at the onset of dental treatment were found to be at a 5-fold higher risk of developing AHT during the course of dental treatment under local infiltration anesthesia. The observed increases in AP, however, did not reach clinically significant levels. The HR values tended to increase with the progress of dental treatment in all patients. HR was lower in hypertensive patients probably due a drug effect.

From September 2013 to March 2014, a cross-sectional survey was conducted in 4021 hypertensive patients aged 40 to 79 years living in Chengdu and Chongqing, China. Fasting plasma glucose (FPG) and 2h plasma glucose (2-hPG) in an oral glucose-tolerance test (OGTT) were used for assessments. Whether the patients previously had diabetes (DM) was determined by their own reports. The survey was carried out by the same questionnaire for all respondents. DM prevalence was 32.0% in hypertensive patients aged 40 to 79 years in Southwest China, with the rates of 29.6% and 33.5% in men and women, respectively (P<0.001). DM prevalence increased with age age and body-mass index. DM prevalence rates were 16.9%, 24.7%, 38.2% and 41.9% in hypertensive patients aged 40–49, 50–59, 60–69 and over 70, respectively. DM prevalence were 30.6%, 27.9%, 37.1%, and 37.4%, for BMI<18.5, 18.5–24.9, 25.0–29.9, and ≥30, respectively. Prevalence of unrecognized DM were 20.8% in hypertensive patients aged 40 to 79 years in Southwest China. Using only fasting blood glucose testing without OGTT would have resulted in 65.0% of missed DM diagnosis in these newly diagnosed patients. The prevalence of DM and unrecognized DM were high in hypertensive patients aged 40 to 79 years in Southwest China.These findings indicate that hypertensive patients aged 40 to 79 years should regularly submit to community-based OGTT screening for timely DM diagnosis.

    Renal denervation (RDN) reduces muscle sympathetic nerve activity (MSNA) and blood pressure (BP) in resistant hypertension. Although a persistent BP-lowering effect has been demonstrated, the long-term effect on MSNA remains elusive. We investigated whether RDN influences MSNA over time. Office BP and MSNA were obtained at baseline, 3, 6, and 12 months after RDN in 35 patients with resistant hypertension. Office BP averaged 166±22/88±19 mm Hg, despite the use of an average of 4.8±2.1 antihypertensive drugs. Baseline MSNA was 51±11 bursts/min ≈2- to 3-fold higher than the level observed in healthy controls. Mean office systolic and diastolic BP significantly decreased by -12.6±18.3/-6.5±9.2, -16.1±25.6/-8.6±12.9, and -21.2±29.1/-11.1±12.9 mm Hg (P<0.001 for both systolic BP and diastolic BP) with RDN at 3-, 6-, and 12-month follow-up, respectively. MSNA was reduced by -8±12, -6±12, and -6±11 bursts/min (P<0.01) at 3-, 6-, and 12-month follow-up. The reduction in MSNA was maintained, despite a progressive fall in BP over time. No such changes were observed in 7 control subjects at 6-month follow-up. These findings confirm previous reports on the favorable effects of RDN on elevated BP and demonstrate sustained reduction of central sympathetic outflow ≤1-year follow-up in patients with resistant hypertension and high baseline MSNA. These observations are compatible with the hypothesis of a substantial contribution of afferent renal nerve signaling to increased BP in resistant hypertension and argue against a relevant reinnervation at 1 year after procedure.

    Bilateral bipolar electric carotid sinus stimulation acutely reduced muscle sympathetic nerve activity (MSNA) and blood pressure (BP) in patients with resistant arterial hypertension but is no longer available. The second-generation device uses a smaller unilateral unipolar disk electrode to reduce invasiveness while saving battery life. We hypothesized that the second-generation device acutely lowers BP and MSNA in treatment-resistant hypertensive patients. Eighteen treatment-resistant hypertensive patients (9 women/9 men; 53±11 years; 33±5 kg/m(2)) on stable medications have been included in the study. We monitored finger and brachial BP, heart rate, and MSNA. Without stimulation, BP was 165±31/91±18 mm Hg, heart rate was 75±17 bpm, and MSNA was 48±14 bursts per minute. Acute stimulation with intensities producing side effects that were tolerable in the short term elicited interindividually variable changes in systolic BP (-16.9±15.0 mm Hg; range, 0.0 to -40.8 mm Hg; P=0.002), heart rate (-3.6±3.6 bpm; P=0.004), and MSNA (-2.0±5.8 bursts per minute; P=0.375). Stimulation intensities had to be lowered in 12 patients to avoid side effects at the expense of efficacy (systolic BP, -6.3±7.0 mm Hg; range, 2.8 to -14.5 mm Hg; P=0.028 and heart rate, -1.5±2.3 bpm; P=0.078; comparison against responses with side effects). Reductions in diastolic BP and MSNA (total activity) were correlated (r(2)=0.329; P=0.025). In our patient cohort, unilateral unipolar electric baroreflex stimulation acutely lowered BP. However, side effects may limit efficacy. The approach should be tested in a controlled comparative study.

    In this cross-sectional study, we hypothesized that hemodialysis patients consuming greater processed meat is associated with hypertension risk, which can be partly explained by the high sodium content in processed meat. From September 2013 to May 2014, one hundred and four patients requiring chronic hemodialysis treatment were recruited from hemodialysis centers. Data on systolic blood pressure and diastolic blood pressure before receiving dialysis, and 3-day dietary records of the recruited patients were collected. HD patients with systolic and diastolic blood pressures greater than140 mmHg and higher than 90 mmHg, respectively, were considered hypertension risk. Protein foods were divided into 4 categories: red meat, white meat, soybeans, and processed meat (e.g., sausage and ham). In a model adjusted for energy intake and hypertension history, additional servings of processed meats was positively associated to systolic blood pressure >140 mmHg (odds ratio [95% confidence interval]: 2.1 [1.0-4.3]), and diastolic blood pressure > 90 mmHg (odds ratio: 2.5 [1.2-5.5]). After adjustment for dietary sodium contents or body mass index (BMI), most associations were substantially attenuated and were no longer significant. In systolic blood pressure greater than140 mmHg, one serving per day of red meats (β = -1.22, P < .05) and white meats (β = -0. 75, P = .05) was associated with a reduced risk compared with one serving per day of processed meats. Similarly, compared with one serving per day of processed meat, a reduced risk of diastolic blood pressure higher than 90 mmHg was associated with one serving per day of red meat (β = -1. 59, P < .05), white meat (β = -0. 62, P < .05). Thus, in these hemodialysis patients, intake of processed meat is significantly positively associated with higher blood pressure risk, and both sodium contents in processed meat and BMI significantly contributes to this association.

    The objective of this investigation was to evaluate gas exchange and cardiopulmonary functional behavior in patients with pulmonary hypertension (PH) before, during and after the change to a prone position. Thirty patients with PH and alterations in gas exchange were included in the study. Gas exchange measurements were performed in four stages: at the baseline supine position and after 30, 120 and 240 minutes in prone position. Also, the patients were evaluated by the six minutes walking test (6MWT) after 30 days in prone position during night's sleep. After four hours in prone position, all patients showed an increase of PaO2 and arterial saturation of oxygen (SaO2), with a decrease of intrapulmonary shunts, improving the gas exchange and therefore the physiological demand imposed by exercise in patients with PH.

  15. Optimal Blood Pressure Goals in Patients With Hypertension at High Risk for Cardiovascular Events.

    Existing epidemiologic and clinical trial data suggest that the blood pressure in patients with hypertension at high risk for cardiovascular events because of coronary artery disease, diabetes mellitus, chronic kidney disease, stroke, or heart failure should be reduced to <140/90 mm Hg in patients younger than 80 years and the systolic blood pressure be reduced to 140-145 mm Hg if tolerated in patients aged 80 years and older. Studies from patients with coronary artery disease, diabetes mellitus, chronic kidney disease, stroke, and heart failure will be discussed that support a blood pressure goal of <140/90 mm Hg in patients younger than 80 years at high risk for cardiovascular events.

    One-hundred five hypertensive patients underwent conventional renal scintigraphy followed 2 or 3 days later by Captopril-enhanced renal scintigraphy, performed 1 hr after premedication with 50 mg of Captopril per os. All patients were then submitted to renal arteriography, performed within 15-30 days. Fifty-five patients had no renal artery stenosis, 29 had unilateral disease, and 21 bilateral. Overall, 34/37 patients were diagnosed by the provocative test as having at least one renal artery affected by a stenosis greater than 50%. Of those with no stenosis (n = 55) or stenosis less than 50% (n = 13) only two cases were falsely positive. Thus sensitivity was 92% and specificity 97%. For single kidney identification with stenosis greater than 50%, sensitivity of renal scintigraphy after Captopril administration was 94% and specificity 98%. Captopril enhanced renal scintigraphy is thus suggested as the first test to be performed in hypertensive patients referred for renal scintigraphic studies. Only those cases with equivocal results require a baseline study for better assessment.

    A placebo-controlled, double-blind, parallel group study was performed with 58 patients to investigate effects of French maritime pine bark extract, Pycnogenol, on patients with hypertension. Supplementation of the patients with 100 mg Pycnogenol over a period of 12 weeks helped to reduce the dose of the calcium antagonist nifedipine in a statistically significant manner. The intake of Pycnogenol decreased endothelin-1 concentrations significantly compared to placebo while concentrations of 6-keto prostaglandin F1a in plasma were significantly higher compared to placebo. Values for nitric oxide (NO) in plasma increased in both groups, but the differences were not significant. Angiotensin II concentrations in plasma were lowered in the placebo group to a larger extent than in the Pycnogenol group. Heart rate, electrolytes and blood urea nitrogen were not changed during treatment in both groups of patients. Unwanted effects observed in both groups were of mild and transient nature, such as gastrointestinal problems, vertigo, headache and nausea. Differences in rate of side effects were not statistically significant between the two groups. Study results support a supplementation with Pycnogenol for mildly hypertensive patients.

    Poor antihypertensive treatment adherence adversely affects blood pressure control. We analyzed US health plan data to assess the impact of fixed- versus loose-dose triple-combination therapy on adherence, clinical, and economic outcomes. Patients initiating triple therapy with an angiotensin receptor blocker, angiotensin-converting enzyme inhibitor, or beta blocker plus amlodipine and hydrochlorothiazide comprised three cohorts. Within-cohort comparisons were made between fixed-dose combinations of two antihypertensives plus a second pill (two pills) or three separate pills. Outcomes included adherence, cardiovascular events, health care resource use, and costs for patients with ≥ 12 months follow-up. A total of 16,290 patients were matched. Patients receiving two pills were more likely to be adherent (P < .001) and less likely to discontinue treatment (P < .001) across all cohorts. Therapy with two versus three pills resulted in significantly lower adjusted risk of cardiovascular events (hazard ratio = 0.76, P = .005) in the beta blocker cohort only. Total adjusted health care costs were significantly lower for two- versus three-pill therapy in the beta blocker cohort only (cost ratio = 0.74 overall, P < .01; 0.71 hypertension-attributable, P < .01). In patients with hypertension requiring triple therapy, fixed-dose combinations that lower pill burden may improve adherence (seen across all cohorts) and clinical outcomes (seen in the beta blocker cohort) without increasing health care costs.

    In recent years, government agencies of many countries have established consensus guidelines for the evaluation and treatment of hypertension. Once published, guidelines tend to be perceived as directives by a variety of health care providers. Unfortunately, these guidelines often do not reflect the practices of most hypertension experts. This report summarizes the opinions of seven hypertension experts concerning the impact of "official" guidelines on clinical practice. In addition, the individual therapeutic recommendations of these panel members are summarized. Their different treatment strategies reflect the diversity of first rate treatment plans that aim to reduce the cardiovascular sequelae in individual patients with essential hypertension. Most importantly, not one of these seven treatment strategies followed the "preferred" treatment of the U.S. guidelines, which recommend diuretics and beta-blockers as first-line therapy. The present authors approach the treatment of hypertension as a means to reduce cardiovascular events. Thus, reduction of blood pressure is not the most important therapeutic endpoint. The panel believes that whereas many different drugs can produce effective blood pressure reduction, the modern primary goal of antihypertensive drug therapy is to select a regimen most likely to prolong the quality and duration of life. In real terms, this means that the primary goal of treatment is the prevention of the major vascular sequelae of hypertension (heart attack, ventricular remodeling, hypertrophy, heart failure, and stroke) that shorten useful life. There are a number of effective hypertensive treatments, which can be selected based on individual patient requirements. However, many consensus guidelines do not allow the flexibility required to optimize individual patient treatment. As a result, health care providers should not feel compelled to regard the preferences of "official" guidelines as the best, modern, state-of-the-art therapy for

    Background Left ventricular hypertrophy (LVH), a marker of cardiac end-organ damage, is frequently found in patients with arterial hypertension and is associated with cardiovascular and cerebrovascular morbidity and mortality. Therefore, LVH regression is an important treatment goal. For amlodipine plus valsartan (A/V) no specific study on LVH has been reported to date. Methods Prospective, open-label, randomized parallel-group study. Patients with essential hypertension and LVH were randomized to 52-week treatment with A/V 10/160 mg (n = 43) or the active comparator losartan/HCT 100/25 mg (L/H, n = 47). Add-on medication was allowed in case of inadequate blood pressure control. LV parameters were measured by cardiovascular magnetic resonance imaging (MRI), and adjudicated in a blinded manner. Study identifiers were NCT00446563 and EudraCT 2006-001977-17. Results In addition to the study treatment, 35% of patients in the A/V group and 49% in the L/H group received additional antihypertensive medication. Compared to baseline, both treatments reduced measures of LVH significantly after 52 weeks (e.g. LV mass index in the A/V group from 64.7 g/m2 by −3.5 g/m2, in the L/H group from 69.1 g/m2 by −4.4 g/m2, p < 0.01 for both). LV ejection fraction and LV volumes were not significantly changed by any regimen. A/V and L/H treatments were well tolerated. Conclusions Both regimen were effective in reducing LV mass compared to baseline and were well tolerated. PMID:27536421

    Pulmonary arterial hypertension (PAH) that occurs in the setting of cirrhosis and portal hypertension is referred to as portopulmonary hypertension (PPHTN). Liver transplantation (LTx) is curative, but the presence of moderate-to-severe PPHTN may be a contraindication for transplantation because of the elevated risk of peri- and post-transplantation morbidity and mortality. We report a successful liver transplantation in a patient with liver cirrhosis after treatment of moderate-to-severe PPHTN with a combination of the dual endothelin receptor antagonist bosentan and the specific phosphodiesterase-5 inhibitor sildenafil.

    Four consecutive 24-h urine samples were collected from 134 male and 134 female placebo-treated patients in the Medical Research Council Trial for Mild Hypertension. Similar samples were collected from age and sex-matched normotensive controls. On the fourth day noradrenaline excretion was 22.05 +/- 1.01 nmol/mmol creatinine in the hypertensives compared with 22.22 +/- 1.16 nmol/mmol creatinine in the controls. Adrenaline excretion on the same day was 6.13 +/- 0.33 nmol/mmol creatinine in the hypertensive subjects compared with 6.32 +/- 0.38 nmol/mmol creatinine in the controls. There was no significant difference for either catecholamine between the two groups. However, in the control group there was a highly significant correlation between excretion of adrenaline and systolic blood pressure (r = 0.218, p = 0.0004) and between noradrenaline excretion and systolic blood pressure (r = 0.200, p = 0.001). Catecholamine excretion and blood pressure were not significantly correlated in the hypertensive patients. There were no significant correlations in either group between catecholamine excretion and heart rate, caffeine intake, nicotine consumption or the Bortner self-assessment score of personality type. This study has found no evidence of elevated sympathoadrenal activity in mild hypertensives. The correlations in the control group may reflect the role of sympathoadrenal activity in acute fluctuations in blood pressure or may suggest that the level of blood pressure within the 'normal' range depends in part on the level of sympathoadrenal activity.

    Pulmonary arterial hypertension is a serious complication of adult congenital heart disease associated with systemic-to-pulmonary shunts. Although early shunt closure restricts development of pulmonary arterial hypertension, patients remain at risk even after repair. The development of pulmonary arterial hypertension is associated with a markedly increased morbidity and mortality. It is important to identify patients with a poor prognosis using disease specific markers. Echocardiography and biomarkers arise as practical tools to determine the risk of mortality. Although pulmonary arterial hypertension cannot be cured, four classes of disease-targeting therapies are currently available and several promising therapies are being studied. There is a shift in drug studies towards more clinically relevant endpoints such as time to clinical worsening and morbidity and mortality events.

    Intravenous prostacyclins are a valuable treatment for patients with severe pulmonary arterial hypertension, leading to improved exercise capacity, haemodynamics, quality of life and survival. Unfortunately, due to the short half-life of these drugs, they need to be administered continuously through central venous catheters. Despite aseptic technique, regular dressing changes, tunneled central venous catheters and patient education, patients are exposed to central venous catheter associated infections. These infections cause significant morbidity and mortality. The clinical presentation, microbiology, consequences and management of these central venous catheter associated infections in pulmonary arterial hypertension patients treated with intravenous prostacyclins are discussed.

    The aim of this study was to compare postprandial hemodynamic changes observed during assumption of the recumbent posture and upright posture in patients with cirrhosis and portal hypertension. Eleven patients with cirrhosis and portal hypertension were studied. Echo-Doppler examinations were performed to measure flow volume in the portal vein (PV), superior mesenteric artery (SMA), and splenic artery (SA) in the fasting condition. Collateral blood flow was indirectly calculated by determining the difference between the sum of SMA, SA, and PV blood flows. After these measurements were done, each patient received a standardized liquid meal and was then randomly assigned to either maintain supine or upright posture, in a crossover design, on 2 different days (recumbent day and upright day). On each study day, the above-mentioned measurements were repeated 30 min and 60 min after the meal. PV blood flow increased significantly after the meal on the recumbent day (P < 0.01) but not on the upright day (P = 0.78). Although there were significant postprandial increases in SMA blood flow on both study days (P < 0.01, P < 0.01), the effect was less pronounced on the upright day than on the recumbent day (P < 0.01). Postprandial SA blood flow showed no change on the recumbent day (P = 0.64), but decreased significantly on the upright day (P < 0.01). The calculated postprandial collateral blood flow increased significantly on the recumbent day (P < 0.05), but showed no change on the upright day (P = 0.53). These results suggest that the upright posture blunts postprandial splanchnic hyperemia in patients with cirrhosis and portal hypertension.

    Background: The self-treatment with complementary and alternative medicines (CAMs) in chronic diseases is portraying an expanding trend worldwide. Yet, little is known concerning patients’ motives to use CAM in the control of blood pressure. Objective: This study aims to explore the self-use of CAM in the management of hypertension and explore patients’ attitudes, perceived benefits, and disclosure to the physician. Materials and Methods: A qualitative technique was adopted and face-to-face interviews, using a validated interview guide, were carried out among twenty hypertensive patients. A purposive sampling method was used to recruit patients at Al-Karama Teaching Hospital in Baghdad; the capital of Iraq; from January to April 2015. All the interviews were audio-recorded, then transcribed verbatim and examined for thematic relationships. Results: Three major themes were identified through thematic content analysis of the interviews. These encompassed patients’ understanding of CAM; experience and perceived benefits; and communication with the doctors. The use of CAM was prevalent among the majority of the respondents. The most commonly used therapies were biological-based practices (herbal remedies, special diet, vitamins, and dietary supplements); traditional therapies (Al-Hijama or cupping); and to a less extent of manipulative body-based therapies (reflexology). Factors influencing the use of CAM were traditions, social relationships, religious beliefs, low-cost therapy, and safety of natural products. Conclusion: The use of CAM was common as a practice of self-treatment among hypertensive patients in Iraq. This was underpinned by the cultural effects, social relationships, religious beliefs, and the perception that natural products are effective and safe. Understanding patients’ usage of CAM is of great importance as long as patient's safety and interaction with the standard prescribed treatment are major concerns. PMID:28216951

    Plasma levels of von Willebrand factor (vWF), a marker of endothelial dysfunction/damage, are elevated in high-risk hypertensive patients and in patients with severe aortic regurgitation (AR). Patients with mild-to-moderate AR, frequently detected in hypertensive elderly, have additional left ventricular morphological and functional dysfunctions. We hypothesized that hypertensive patients with mild-to-moderate AR may have enhanced endothelial and/or left ventricular dysfunctions that may lead to a deteriorated prognosis. We measured vWF, prothrombin F1+2 (F 1+2) as a marker of thrombin generation, brain natriuretic peptide (BNP) in 104 hypertensive patients with mild-to-moderate AR and 66 hypertensive patients without AR. The left ventricular diameter at systole (LVDs) and left ventricular posterior wall thickness (LVWT) were determined by echocardiography and indexed by body surface area (LVDs/BSA and LVWT/BSA). VWF (median, interquartile range (IQR) 154, 120-196%) and BNP (34.7 pg ml(-1), 15-65%) levels were greater in patients with AR than in those without AR (135, 98-175% and 20, 10.3-49 pg ml(-1)). All patients were prospectively followed up for cardiac events during the period of median 43 months (IQR 31-81). Patients with AR had an increased risk of cardiac events (regression ratio (RR) 1.87, 95% confidence interval 1.28-2.87) when compared to those without AR. A multivariate Cox hazard analysis indicated that log vWF (RR 4.93) and log BNP (RR 1.9) were independent predictors in patients with AR. VWF was an independent predictor of clinical outcome in hypertensive patients with mild-to-moderate AR.

    The prevalence of hypertensive disorders in pregnancy is increasing. The etiology and pathophysiology of hypertensive disorders in pregnancy remain poorly understood. Hypertensive disorders are a major cause of maternal and perinatal morbidity and mortality. Treatment of hypertension decreases the incidence of severe hypertension, but it does not impact rates of preeclampsia or other pregnancy complications. Several antihypertensive medications are commonly used in pregnancy, although there is a lack of randomized controlled trials. Severe hypertension should be treated immediately to prevent maternal end-organ damage. Appropriate antepartum, intrapartum, and postpartum management is important in caring for patients with hypertensive disorders.

    Atherosclerotic renal artery stenosis may result in hypertension and ischemic nephropathy. Renal artery endovascular stenting has emerged as current therapy; however, the percentage of patients who benefit from this procedure is still not well established. The authors studied 116 hypertensive patients with atherosclerotic renovascular stenosis who underwent successful renal artery stenting for the first time. At 1 year, there was a significant overall decrease in blood pressure in the group after stenting; however, there was no change in renal function. Also, no significant change in the number of antihypertensive drugs was noted. Blood pressure improved in 55% of the patients, worsened in 14%, and remained unchanged in 31%. Renal function improved in 16% of the patients, worsened in 30%, and remained stable in 54%. In relation to blood pressure control, patients with resistant or difficult-to-control hypertension showed the most improvement in blood pressure control after stenting.

    Abstract Hypertension and type 2 diabetes mellitus (DM) are among the main risk factors for the development of cardiovascular disease. Pharmacotherapy for DM should not only improve blood glucose control, but also provide beneficial glucose-independent cardiovascular effects. The central systolic blood pressure (SBP) has become more important than the brachial SBP in the assessment of cardiovascular risk. This case report describes the effect of vildagliptin, a dipeptidyl peptidase-4 (DPP-4) inhibitor, on the central SBP in a 54-year-old woman with hypertension and DM. She was submitted to applanation tonometry (AT) before and after vildagliptin association. AT of the radial artery is a non-invasive method that indirectly assesses arterial stiffness by calculating the central SBP and the augmentation index (AIx). After 3 months of follow-up using vildagliptin, central SBP and AIx were improved. Moreover, she presented better glycemic control. This case suggests an effect of DPP-4 inhibitor on arterial stiffness parameter (central SBP) in a hypertensive and diabetic patient, which shows a glucose-independent beneficial cardiovascular effect of this group of drugs.

    Addison's disease may be complicated by hypertension and less commonly by heart failure. We review the pathophysiology of the renin-angiotensin-aldosterone axis in Addison's disease and how this is altered in the setting of hypertension and heart failure. An essential first step in management in both conditions is optimizing glucocorticoid replacement and considering dose reduction if excessive. Following this, if a patient with Addison's disease remains hypertensive, the fludrocortisone dose should be reviewed and reduced if there are clinical and/or biochemical signs of mineralocorticoid excess. In the absence of such signs, where the renin is towards the upper end of the normal range or elevated, an angiotensin II (AII) receptor antagonist or angiotensin converting enzyme (ACE) inhibitor is the treatment of choice, and the fludrocortisone dose should remain unchanged. Dihydropyridine calcium channel blockers are clinically useful as second line agents, but diuretics should be avoided. In the setting of heart failure, there is an increase in total body sodium and water; therefore, it is appropriate to reduce and rarely consider ceasing the fludrocortisone. Loop diuretics may be used, but not aldosterone antagonists such as spironolactone or eplerenone. Standard treatment with ACE inhibitors, or as an alternative, AII receptor antagonists, are appropriate. Measurements of renin are no longer helpful in heart failure to determine the volume status but plasma levels of brain natriuretic peptide (BNP/proBNP) may help guide therapy.

    Liver damage influenced by alcohol is already associated with the development of a portal hypertension at an early stage. With the aid of laparoscopic transhepatic manometry we determined the pressure levels in the branches of the portal and hepatic veins in 15 patients (16 examinations) comprising 14 men and 1 women, with alcoholic toxic liver damage. It was shown that already with alcoholic parenchymal damage associated with portal and centrolobular fibrosis, a portal hypertension is initiated, the greatest manifestation of which is found in the group with histological changes taking the form of a remodelling (distorsion of architecture) or cirrhosis. The level of alcohol consumption has no direct influence on the level of pressure in the vascular systems investigated. Ther is, however, a correlation between the level of alcohol consumption, extent of fibrosis and portal hypertension. For the clinico-chemical parameters investigated (Gamma-glob., GOT, GPT, GLDH, gamma-GT, alkaline phosphatase, bilirubin) no significant differences were found dependent on the level of alcohol consumption or the degree of fibrosis.

    The detection of renovascular disease (RVD) has particular relevance in hypertensive patients (HP) who have symptoms of target organ damage. To evaluate the possibility of RVD in HP undergoing myocardial perfusion scintigraphy for chest pain symptoms, posterior renal images were obtained at 1-3 hours after Tl-201 injection. Analog and computer images were obtained for 5 minutes in 45 HP; 12 patients with no history of hypertension or renal disease served as normal controls. For qualitative analysis, images were coded and read by three observers as to symmetry of renal uptake. Differential renal uptake of Tl-201 (DRU) was quantitated on computer images. In normal controls, uptake was agreed on as symmetric. In HP, 6 patients had marked asymmetry of DRU and 4 had possibly significant asymmetry; 2 had decreased uptake in both kidneys suggesting bilateral RVD or nephrosclerosis. Objective correlation with DRU was obtained in 10 HP who had contrast angiography, confirming 4 cases of unilateral RVD and 2 of bilateral RVD. Thirteen patients also had renography with Tc-99m DTPA; differential renal function by this modality correlated well with DRU of Tl-201 (r = 0.98). Thus, DRU of Tl-201 can be used as a supplement to myocardial scintigraphy to identify HP who require further evaluation and treatment of RVD.

    In patients with an atrial septal defect and severe pulmonary hypertension, it is important to determine whether the latter is reversible before percutaneous or surgical closure. In addition to determining pulmonary resistance, one simple technique is to transiently occlude the septal defect using a balloon catheter and to evaluate the hemodynamic response. We defined a positive response as a > or = 25% reduction in mean pulmonary artery pressure during occlusion relative to the basal level, without a fall in systemic pressure or an increase in ventricular end-diastolic pressure. The study included five patients aged over 60 years with an atrial septal defect and severe pulmonary hypertension who were referred for percutaneous closure. In one patient, the test gave a negative result and closure of the atrial septal defect was not performed. In the remaining four, closure was indicated. In three patients, closure was performed percutaneously, while the fourth underwent surgery. The drop in pulmonary pressure observed during the test was maintained over the long term at a mean follow-up time of 22 months.

  16. Renoprotective effects of the L-/T-type calcium channel blocker benidipine in patients with hypertension.

    PubMed

    Tomino, Yasuhiko

    2013-05-01

    The renoprotective effects of benidipine, a calcium channel blocker (CCB) developed in Japan, are reviewed herein. Benidipine has a sustained antihypertensive effect independent of its blood concentration since it binds to dihydropyridine (DHP) receptors via a "membrane approach" (approach to the cell membrane followed by long retention at the DHP binding site). Benidipine dilates glomerular afferent and efferent arterioles equally through inhibition of Ttype Ca channels. Thus, it may cause a decrease of intraglomerular pressure and is superior to CCBs (capable of inhibiting only L-type Ca channels) in terms of suppression of proteinuria. Additionally, benidipine suppresses worsening of renal function more powerfully than CCBs (suppressing only L-type Ca channels), allowing better prognosis as to renal function. The inhibitory effect of benidipine on T-type calcium channels results in the suppression of aldosterone formation in the adrenal glands and of oxidative stress induced by aldosterone. Thus, the aldosterone-inhibitory and antioxidant activities of benidipine mediated by inhibition of T-type calcium channels would result in renoprotection and suppression of disease progression in hypertensive patients with chronic kidney disease (CKD). If such patients have proteinuria, renin-angiotensin system (RAS) inhibitors are used as first-line drugs, but benidipine, as an L-/T-type CCB, is recommended when they require some concomitant drugs. Moreover, the superiority of RAS inhibitors has not been demonstrated in hypertensive patients with CKD and without proteinuria. Thus, in such patients, benidipine should be considered as a first-line antihypertensive drug.

    Primary pulmonary hypertension (PPH) is a progressive disease with high mortality. Administration of i.v. epoprostenol has demonstrated improved exercise tolerance, haemodynamics, and survival. The orally active, dual endothelin receptor antagonist bosentan improves exercise endurance, haemodynamics, and functional class over the short term. To determine the effect of first-line bosentan therapy on survival, this study followed 169 patients with PPH treated with bosentan in two placebo-controlled trials and their extensions. Data on survival and alternative treatments were collected from September 1999 (start of the first placebo-controlled study) to December 31, 2002. Observed survival up to 36 months was reported as Kaplan-Meier estimates and compared with predicted survival as determined for each patient by the National Institutes of Health Registry formula. Kaplan-Meier survival estimates were 96% at 12 months and 89% at 24 months. In contrast, predicted survival was 69% and 57%, respectively. In addition, at the end of 12 and 24 months, 85% and 70% of patients, respectively, remained alive and on bosentan monotherapy. Factors that predicted a worse outcome included World Health Organization Functional Class IV and 6-min walk distance below the median (358 m) at baseline. First-line bosentan therapy was found to improve survival in patients with advanced primary pulmonary hypertension.

    BACKGROUND Pulmonary hypertension (PH) is common in heart failure patients. Literature on PH in heart failure is sparse in Nigeria. This study was carried out to determine the prevalence of PH in heart failure patients and ascertain the relationship between left ventricular systolic and diastolic function and the degree of PH. METHODS A total of 125 heart failure patients had echocardiography done. PH was diagnosed using tricuspid regurgitation jet and pulmonary ejection jet profile. RESULTS PH was present in 70.4% of heart failure patients. Estimated mean pulmonary arterial pressure increased with increasing severity of systolic and diastolic dysfunction and had significantly negative correlation with ejection fraction, fractional shortening, and early mitral annular tissue diastolic velocity (E′), but positive correlation with left ventricular end-systolic volume, right ventricular dimension, transmitral E to A ratio, and E/E′ ratio. CONCLUSION PH is very common in heart failure and has significant relationship with left ventricular function. PMID:27867305

    To assess the regional cardiac adrenergic innervation in patients with essential hypertension (EHT), simultaneous iodine-123 metaiodobenzylguanidine ((123I)MIBG) and thallium-201 (201Tl) myocardial imagings were performed in five patients with EHT, seven patients with hypertrophic cardiomyopathy (HCM), and seven normal subjects. Short axial images at rest were divided into five segments: anterior, septal, posterior, lateral, and apical segments. Percent regional uptake (%RU) of 201Tl except the septal segment in patients with EHT showed no significant difference. However, the %RU of (123I)MIBG at posterior, lateral, and apical segments was significantly lower than that at anterior and septal segments in EHT. This intraimage heterogeneity of (123I)MIBG was also observed in HCM. These results suggest that there is a difference in regional adrenergic innervation of the left ventricle with myocardial hypertrophy.

    It is unknown whether the decline in blood pressure (BP) after renal denervation (RDN) is caused by denervation itself or concomitantly improved drug adherence. We aimed to investigate the BP lowering effect of RDN in true treatment-resistant hypertension by excluding patients with poor drug adherence. Patients with resistant hypertension (n=18) were referred for a thorough clinical and laboratory work-up. Treatment-resistant hypertension was defined as office systolic BP>140 mm Hg, despite maximally tolerated doses of ≥ 3 antihypertensive drugs, including a diuretic. In addition, ambulatory daytime systolic BP>135 mm Hg was required after witnessed intake of antihypertensive drugs to qualify. RDN (n=6) was performed with Symplicity Catheter System. The mean office and ambulatory BPs remained unchanged at 1, 3, and 6 months in the 6 patients, whereas there was no known change in antihypertensive medication. Two patients, however, had a fall in both office and ambulatory BPs. Our findings question whether BP falls in response to RDN in patients with true treatment-resistant hypertension. Additional research must aim to verify potential BP lowering effect and identify a priori responders to RDN before this invasive method can routinely be applied to patients with drug-resistant hypertension.

    We studied the impact of hypertension along with traditional and new cardiovascular risk factors on the structural and functional properties of arteries in psoriatic arthritis (PsA) patients. We examined 42 PsA subjects (aged 51±9 years) stratified according to hypertensive status (19 normotensive, PsA-NT and 23 hypertensives, PsA-HT). Thirty-eight normotensive subjects (C-NT) and 23 hypertensives (C-HT) comparable by age and sex served as controls. Mean carotid intima-media thickness (mean-IMT) and mean of the maximum IMT (M-Max) were evaluated by ultrasound in carotid artery segment bilaterally. Post-occlusion flow-mediated dilation (FMD) of the brachial artery was evaluated by ultrasonography. These parameters were correlated with risk factors, markers of inflammation and disease activity. Values of mean-IMT were higher in both groups of PsA patients compared with C-NT (0.68 mm in PsA-NT and 0.75 mm in PsA-HT versus 0.61 mm in C-NT). PsA-HT displayed higher M-Max (0.95 mm) versus both C-HT (0.71 mm) and PsA-NT (0.79 mm). FMD was impaired in PsA subjects compared with C-NT (5.7% in PsA-NT and 6.0% PsA-HT versus 9.3% in C-NT), whereas there was no difference among PsA-HT, PsA-NT, and C-HT groups. Values of carotid IMT were directly related to tumor necrosis factor (TNF)-α, osteoprotegerin (OPG), blood pressure and lipid profile levels. FMD showed an inverse relationship with TNF-α and blood pressure, but no correlation with lipids. In conclusion, PsA per se implies a pro-atherogenic remodeling, which is enhanced by the hypertensive status. TNF-α and OPG may have an independent role in the development of such vascular damage.

    Temporal sensitivity was assessed in patients with primary open-angle glaucoma (POAG) and ocular hypertension (OHT). Three measures of flicker sensitivity were obtained: psychophysical modulation thresholds, visual-evoked potentials (VEPs), and focal electroretinograms (FERGs). We found elevated psychophysical thresholds at higher temporal frequencies (30-50 Hz) in patients with POAG, relative to thresholds for age-matched controls. The OHT patients had elevated psychophysical thresholds only at 50 Hz. On the other hand, VEP amplitudes in POAG patients were reduced at all temporal frequencies, with the magnitude of the loss increasing with temporal frequency. The OHT patients, however, showed no reductions in VEP amplitude at any temporal frequency. Finally, POAG patients' FERG amplitudes were reduced at 30-50 Hz; whereas FERG amplitudes in the OHT patients were normal at all temporal frequencies. These results indicate that OHT patients can exhibit psychophysical threshold losses at high temporal frequencies which are not observed in the suprathreshold electrophysiological amplitude measures. On the other hand, patients with POAG show both psychophysical and VEP losses across a range of temporal frequencies. In addition, the decreases in FERG amplitudes in POAG patients suggest changes in the functioning of the outer retina in this disease.

    Background/Aim: Among the various methods for evaluating gastric emptying, the real-time ultrasound is safe, does not require intubation, or rely on either radiologic or radionuclide technique. The aim of our work was to measure the gastric emptying in pediatric patients with portal hypertension by using the real-time ultrasound. Patients and Methods: Forty patients with portal hypertension with mean age 7 ± 2.8 years and 20 healthy children as a control group underwent gastric emptying study by using real-time ultrasound. The cross-sectional area of the gastric antrum was measured in the fasting state and then each subject was allowed to drink tap water then calculated by using formula area (π longitudinal × anteroposterior diameter/4). The intragastric volume was assumed to be directly proportional to the cross-sectional area of the antrum. Results: The mean gastric emptying half-time volume was significantly delayed in portal hypertension patients (40 ± 6.8 min) compared with the control subjects (27.1 ± 3.6) min (P<0.05). Patients with extrahepatic portal vein obstruction had significant delayed gastric emptying in comparison to patients with portal hypertension due to other etiologies (36.14 ± 4.9 vs 44.41 ± 6.04 min; P<0.01). Conclusion: Ultrasound is a noninvasive and a reliable method for measuring gastric emptying in pediatric patients. Gastric emptying was significantly delayed in patients with portal hypertension. Etiology of portal hypertension may influence gastric emptying time in patients with chronic liver disease. PMID:22249091

    The oxygen therapy, involving the KI-3M respiratory apparatus administered in the positive pressure regimen on expiration (8-10 cm aq. c.), used, before hospitalization, within the complex therapy of patients with pulmonary edema triggered by hypertensive crisis arrests fast enough the pulmonary edema, cuts the working time of an ER crew and promotes the ER efficiency. The key clinical manifestations of pulmonary edema were found to begin to go down on minutes 5 to 10 after the administration of artificial lungs ventilation (ALV) by oxygen with the positive pressure being on expiration end; such signs were totally stopped in 20-25 minutes.

    The study with the use of laser Doppler flowmetry has revealed pathological changes in the microcirculatory system of patients with arterial hypertension. Their treatment with a low-frequency magnetic field showed that its effect on microcirculation depends on the regime and site of application of magnetotherapy as well as its combination with other physical factors. Frontal application of the magnetic field had the most pronounced beneficial effect on dynamic characteristics of microcirculation. Pulsed regime of magnetotherapy was more efficacious than conventional one. Amplipulse magnetotherapy produced better results than monotherapy.

    Background Gastrointestinal dysmotility may be involved in the development of bacterial translocation and infection in patients with liver cirrhosis. The aim of the present study was to describe gastric, small intestinal and colorectal motility and transit in patients with liver cirrhosis and portal hypertension using a magnet-based Motility Tracking System (MTS-1) and standard radiopaque markers. Methods We included 15 patients with liver cirrhosis (8 Child-Pugh A, 6 Child-Pugh B, and 1 Child-Pugh C) and portal hypertension (11 males, median age 54 years (range 38–73), median hepatic venous pressure gradient 18 mmHg (range 12–37)), and 18 healthy controls (8 males, median age 58 years (range 34–64)). The gastric emptying time and small intestinal motility were evaluated by MTS-1, and the total gastrointestinal transit time was assessed by radiopaque markers and abdominal radiographs. Results The velocity through the proximal small intestine was significantly higher in cirrhotic patients (median 1.27 metres (m)/hour, range 0.82–2.68) than in the healthy controls (median 1.00 m/hour, range 0.46–1.88) (p = 0.03). Likewise, the magnet travelled significantly longer in both fast (p = 0.04) and slow movements (p = 0.05) in the patient group. There was no significant difference in either gastric emptying time—23 minutes (range 5–131) in patients and 29 minutes (range 10.5–182) in healthy controls (p = 0.43)—or total gastrointestinal transit time—1.6 days (range 0.5–2.9) in patients and 2.0 days (range 1.0–3.9) in healthy controls (p = 0.33). No correlation was observed between the hepatic venous pressure gradient and the velocity of the magnet through the small intestine. Conclusion Patients with liver cirrhosis and portal hypertension demonstrated faster-than-normal transit through the proximal small intestine. This may be due to an overactive bowel, as suggested by previous studies. PMID:23216853

    Background Hypertension frequently coexists with type 2 diabetes (DM), and increases the risk of cardiovascular outcomes. The aim of the study was to obtain/maintain blood pressure (BP) goals (ADA/JNC 7) according to a stepwise algorithm using the medication supplied by the Brazilian government. Methods A one-year, single-arm interventional study conducted with type 2 diabetes patients. Intervention consisted of intensification of lifestyle changes and sequential prescription of drugs: diuretic; ACE inhibitors; β-adrenergic blocking agent and calcium channel blocking agent if BP >130/80 mmHg. Results Seventy-eight patients completed the trial. During intervention, the number of antihypertensive tablets rose (3.6 ± 3.5 vs. 5.9 ± 3.5 pills/patient; p <0.001), as the number of antihypertensive classes increased (1.8 ± 1.0 vs. 2.70 ± 1.2; p < 0.01) and the overall drop of BP was 11 mmHg for SBP (145.0 ± 22.8 vs. 133.7 ± 20.9 mmHg; p < 0.01) and 5 mmHg for DBP (78.7 ± 11.5 vs. 73.7 ± 10.5 mmHg; p = 0.001). Although the number of patients with BP in target almost doubled [14 (18.7%) vs. 30 (38.5%) p = 0.008], less than 40% of the patients achieved the proposed goals. Conclusions A BP algorithm applied to type 2 diabetic and hypertensive patients is able to lower BP, however more than half of the patients did not achieve the ADA/JNC 7 targets demonstrating the complexity of BP control in this population.

    Purpose: Despite the importance of patients believes as one of the most important predictors of treatment adherence behavior, it is rarely considered in numerous studies. Then the current survey was aimed to develop and study the beliefs about medicines questionnaire (BMQ) in patients with hypertension. Materials and Methods: The BMQ developed by Horn and et al. was used in the current study. This questionnaire included 18 questions in both public and private beliefs regarding drug. Face and content validity of the tool was investigated using expert’s panel. In final, aforementioned tool was tested in 612 participants. To explore structure validity and internal consistency, exploratory and confirmatory factor analysis and alpha coefficient was conducted. To evaluate the final validity of instrument, the mean score of the beliefs about medicines of patients with appropriate medication adherence were compared to patients without medication adherence. Results: The mean age of patients was 44.08 ± 10.38 years. Women were 314 of participants. Calculated face validity by the impact score for each item indicated that all the items of the questionnaire had the impact score of more than 1.5. In total, all items had scored higher than 0.79 by considering 18 items for content validity. The average of content validity index for the questionnaire was 0.93. Load of factors were in the range of 0.51 to 0.79. Four items explained % 57 of the total variance. Comparison of all instrument items in the two groups showed that
