    Hypertension remains a major societal problem affecting 76 million, or approximately one third, of US adults. While more prevalent in the older population, an increasing incidence in the younger population, including athletes, is being observed. Active individuals, like the young and athletes, are viewed as free of diseases such as hypertension. However, the increased prevalence of traditional risk factors in the young, including obesity, diabetes mellitus, and renal disease, increase the risk of developing hypertension in younger adults. Psychosocial factors may also be contributing factors to the increasing incidence of hypertension in the younger population. Increased left ventricular wall thickness and mass are increasingly found in young adults on routine echocardiograms and predict future cardiovascular events. This increasing incidence of hypertension in the young calls for early surveillance and prompt treatment to prevent future cardiac events. In this review we present the current epidemiological data, potential mechanisms, clinical implications, and treatment of hypertension in young patients and athletes.

    Secondary hypertension occurs in a significant proportion of adult patients (~10%). In young patients, renal causes (glomerulonephritis) and coarctation of the aorta should be considered. In older patients, primary aldosteronism, obstructive sleep apnoea and renal artery stenosis are more prevalent than previously thought. Primary aldosteronism can be screened by taking morning aldosterone and renin levels, and should be considered in patients with severe, resistant or hypokalaemia-associated hypertension. Symptoms of obstructive sleep apnoea should be sought. Worsening of renal function after starting an angiotensin-converting enzyme inhibitor suggests the possibility of renal artery stenosis. Recognition, diagnosis and treatment of secondary causes of hypertension lead to good clinical outcomes and the possible reversal of end-organ damage, in addition to blood pressure control. As most patients with hypertension are managed at the primary care level, it is important for primary care physicians to recognise these conditions and refer patients appropriately. PMID:27211205

    Objective. To determine the prevalence, risk factors, characteristics, and treatment practices of known adult hypertensives in Saudi Arabia. Methods. Cross-sectional community-based study using the WHO stepwise approach. Saudi adults were randomly chosen from Primary Health Care Centers catchment areas. Data was collected using a questionnaire which included sociodemographic data, history of hypertension, risk factors, treatment practices, biochemical and anthropometric measurements. Collected data was cheeked, computer fed, and analysed using SPSS V17. Results. Out of 4719 subjects (99.2% response), 542 (11.5%) subjects were known hypertensives or detected by health workers in the past 12 months. Hypertension was significantly associated with age, gender, geographical location, education, employment, diabetes, physical inactivity, excess body weight, and ever smoking. Multiple logistic analysis controlling for age showed that significant predictors of hypertension were diabetes mellitus, ever smoking, obesity, and hypercholesteremia. Several treatment modalities and practices were significantly associated with gender, age, education, and occupation. About 74% were under prescribed treatment by physicians, 62% on dietary modification, 37% attempted weight reduction, 27% performed physical exercise, and less than 7% used herbs, consulted traditional healers or quitted smoking. Income was not significantly associated with any treatment modality or patient practices. Conclusion. Hypertension (known and undetected) is a major chronic health problem among adults in Saudi Arabia. Many patients' practices need changes. A comprehensive approach is needed to prevent, early detect, and control the disease targeting, the risk factors, and predictors identified. PMID:21318133

    Objective To evaluate the influence of pulmonary hypertension in the ultra-fast-track anesthesia technique in adult cardiac surgery. Methods A retrospective study. They were included 40 patients divided into two groups: GI (without pulmonary hypertension) and GII (with pulmonary hypertension). Based on data obtained by transthoracic echocardiography. We considered as the absence of pulmonary hypertension: a pulmonary artery systolic pressure (sPAP) <36 mmHg, with tricuspid regurgitation velocity <2.8 m/s and no additional echocardiographic signs of PH, and PH as presence: a sPAP >40 mmHg associated with additional echocardiographic signs of PH. It was established as influence of pulmonary hypertension: the impossibility of extubation in the operating room, the increase in the time interval for extubation and reintubation the first 24 hours postoperatively. Univariate and multivariate analyzes were performed when necessary. Considered significant a P value <0.05. Results The GI was composed of 21 patients and GII for 19. All patients (100%) were extubated in the operating room in a medium time interval of 17.58±8.06 min with a median of 18 min in GII and 17 min in GI. PH did not increase the time interval for extubation (P=0.397). It required reintubation of 2 patients in GII (5% of the total), without statistically significant as compared to GI (P=0.488). Conclusion In this study, pulmonary hypertension did not influence on ultra-fast-track anesthesia in adult cardiac surgery. PMID:27163419

    Increased QT dispersion is associated with sudden cardiac death in congestive cardiac failure, hypertrophic cardiomyopathy and following myocardial infarction. Patients with hypertension--in particular, those with left ventricular hypertrophy (LVH)--are also at greater risk of sudden cardiac death. We examined whether QT dispersion, which is easily obtained from a routine ECG, correlates with LVH. One-hundred untreated patients with systemic hypertension and 78 normotensives had QT dispersion measured manually from a surface 12-lead electrocardiogram and two-dimensional echocardiography performed to measure interventricular septal thickness, posterior wall thickness and left ventricular internal diameter. Office blood pressure was also recorded. Multivariate analysis demonstrated significant relationships between QT dispersion and office systolic blood pressure, and left ventricular mass index. Manual measurement of QT dispersion might be a simple, noninvasive screening procedure to identify those hypertensives at greatest risk of sudden cardiac death in a third-world country.

    We present a rare case of spontaneous trans-splenic shunt and intra-splenic collaterals in a patient with liver cirrhosis and portal hypertension. The shunt and presence of cirrhosis and portal hypertension was incidentally detected by abdominal computed tomographic imaging during evaluation for abdominal pain. There has been a single report on the presence of trans-splenic shunt in two children with extra-hepatic portal venous obstruction but no cases that report intra-splenic collaterals: to the best of our knowledge, this is the first reported case of spontaneous trans-splenic shunt in the presence of intra-splenic collaterals and incidental multiple splenic artery aneurysms that developed in an adult with compensated cirrhosis and portal hypertension.

    The goal of total anomalous pulmonary venous connection repair is to obtain an unobstructed communication between the pulmonary veins and the left atrium and removing intracardiac shunting. However, pulmonary venous obstruction orstenosis may be seen in 5-10% of patients, is usually evident in the first 6 months following surgery and may lead to pulmonary congestion, pulmonary arterial hypertension, and late mortality. In such cases, early intervention may be indicated before irreversible secondary changes occur. We present the case and the therapeutic approach of an adolescent patient with total anomalous pulmonary venous drainage to the superior vena cava operated in infancy who developed pulmonary venous obstruction and secondary severe pulmonary arterial hypertension.

    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. PMID:26933708

    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.

    Hypertension is frequently associated with primary hyperparathyroidism, yet the mechanism of such hypertension is unknown. Parathyroid hypertensive factor (PHF) is a circulating hypertensive factor found in a proportion of human essential hypertensive patients as well as in spontaneously hypertensive rats (SHR). In the latter case, PHF has been shown to be secreted by the parathyroid gland. The purpose of this study was to determine if PHF expression might be responsible for the hypertension seen in primary hyperparathyroidism. Ten hypertensive and 10 normotensive primary hyperparathyroid patients underwent measurement of blood pressure and PHF pre- and post-parathyroidectomy. Cases reported are those of parathyroid adenomas. There were no significant differences between the hypertensive and normotensive groups preoperatively except that 9 out of 10 of the hypertensive group had significant PHF levels (mean 11 +/- 2 mm Hg vs 0.6 +/- 2 mm Hg, respectively, p = 0.003). Post-operative change in mean arterial pressure could be predicted by pre-operative PHF level, with all PHF-positive patients showing a fall in blood pressure (r = -0.73, p < 0.01). Post-operatively, PHF was undetectable in PHF-positive patients. These results suggest that the parathyroid gland can express PHF in humans and that such expression may be responsible for a proportion of the high reported incidence of hypertension in primary hyperparathyroidism.

    The authors' objective was to gain a better understanding of minority patients' beliefs about hypertension and to use this understanding to develop a model to explain gaps in communication between patients and clinicians. Eighty-eight hypertensive black and Latino adults from 4 inner-city primary care clinics participated in focus groups to elucidate views on hypertension. Participants believed that hypertension was a serious illness in need of treatment. Participants' diverged from the medical model in their beliefs about the time-course of hypertension (believed hypertension was intermittent); causes of hypertension (believed stress, racism, pollution, and poverty were the important causes); symptoms of hypertension (believed hypertension was primarily present when symptomatic); and treatments for hypertension (preferred alternative treatments that reduced stress over prescription medications). Participants distrusted clinicians who prioritized medications that did not directly address their understanding of the causes or symptoms of hypertension. Patients' models of understanding chronic asymptomatic illnesses such as hypertension challenge the legitimacy of lifelong, pill-centered treatment. Listening to patients' beliefs about hypertension may increase trust, improve communication, and encourage better self-management of hypertension.

    Abstract Previous epidemiological studies have suggested that uric acid is an independent risk factor for incident hypertension, whereas few studies have evaluated the effect of hyperuricemia on blood pressure control in hypertensive patients. We investigated whether hyperuricemia predicts uncontrolled hypertension through a large-scale prospective cohort study with hypertensive patients treated with fimasartan in the Republic of Korea (the Kanarb–Metabolic Syndrome study). Of the 10,601 hypertensive patients who were recruited from 582 private clinics and 11 university hospitals at baseline, 7725 completed the follow-up after 3 months of fimasartan medication, and 6506 were included in the analysis after excluding those with missing values. We estimated the risk of uncontrolled hypertension after 3 months (≥130/80 mm Hg in those with diabetes or chronic renal failure and ≥140/90 mm Hg in the remaining patients) related with baseline hyperuricemia (serum uric acid ≥7 mg/dL in males ≥6 mg/dL in females) using multiple logistic regression models. Hyperuricemia increased the risk of uncontrolled hypertension after 3 months of fimasartan medication (odds ratio, 1.247; 95% confidence interval, 1.063–1.462). Males in the highest quartile of uric acid level were at a 1.322 (95% confidence interval, 1.053–1.660) times higher risk of uncontrolled hypertension in reference to the lowest quartile; the same analyses in females were not significant. Patients without metabolic syndrome had significantly higher odds of uncontrolled hypertension with hyperuricemia (odds ratio, 1.328; 95% confidence interval, 1.007–1.751). Hyperuricemia predicted uncontrolled hypertension even after 3 months of fimasartan treatment in hypertensive patients. PMID:27428212

    Allopurinol lowers blood pressure in adolescents and has other vasoprotective effects. Whether similar benefits occur in older individuals remains unclear. We hypothesized that allopurinol is associated with improved cardiovascular outcomes in older adults with hypertension. Data from the United Kingdom Clinical Research Practice Datalink were used. Multivariate Cox-proportional hazard models were applied to estimate hazard ratios for stroke and cardiac events (defined as myocardial infarction or acute coronary syndrome) associated with allopurinol use over a 10-year period in adults aged >65 years with hypertension. A propensity-matched design was used to reduce potential for confounding. Allopurinol exposure was a time-dependent variable and was defined as any exposure and then as high (≥300 mg daily) or low-dose exposure. A total of 2032 allopurinol-exposed patients and 2032 matched nonexposed patients were studied. Allopurinol use was associated with a significantly lower risk of both stroke (hazard ratio, 0.50; 95% confidence interval, 0.32-0.80) and cardiac events (hazard ratio, 0.61; 95% confidence interval, 0.43-0.87) than nonexposed control patients. In exposed patients, high-dose treatment with allopurinol (n=1052) was associated with a significantly lower risk of both stroke (hazard ratio, 0.58; 95% confidence interval, 0.36-0.94) and cardiac events (hazard ratio, 0.65; 95% confidence interval, 0.46-0.93) than low-dose treatment (n=980). Allopurinol use is associated with lower rates of stroke and cardiac events in older adults with hypertension, particularly at higher doses. Prospective clinical trials are needed to evaluate whether allopurinol improves cardiovascular outcomes in adults with hypertension.

    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.

    Objective: To investigate HIV, its treatment, and hypertension as stroke risk factors in Malawian adults. Methods: We performed a case-control study of 222 adults with acute stroke, confirmed by MRI in 86%, and 503 population controls, frequency-matched for age, sex, and place of residence, using Global Positioning System for random selection. Multivariate logistic regression models were used for case-control comparisons. Results: HIV infection (population attributable fraction [PAF] 15%) and hypertension (PAF 46%) were strongly linked to stroke. HIV was the predominant risk factor for young stroke (≤45 years), with a prevalence of 67% and an adjusted odds ratio (aOR) (95% confidence interval) of 5.57 (2.43–12.8) (PAF 42%). There was an increased risk of a stroke in patients with untreated HIV infection (aOR 4.48 [2.44–8.24], p < 0.001), but the highest risk was in the first 6 months after starting antiretroviral therapy (ART) (aOR 15.6 [4.21–46.6], p < 0.001); this group had a lower median CD4+ T-lymphocyte count (92 vs 375 cells/mm3, p = 0.004). In older participants (HIV prevalence 17%), HIV was associated with stroke, but with a lower PAF than hypertension (5% vs 68%). There was no interaction between HIV and hypertension on stroke risk. Conclusions: In a population with high HIV prevalence, where stroke incidence is increasing, we have shown that HIV is an important risk factor. Early ART use in immunosuppressed patients poses an additional and potentially treatable stroke risk. Immune reconstitution inflammatory syndrome may be contributing to the disease mechanisms.

    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.

    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

  2. [Severe hypertension: definition and patients profiles].

    Severe arterial hypertension gathers relatively different clinical situations explained by the heterogeneity of the definitions of this clinical setting. From a medical point of view, severe hypertension is a short course situation defined by very high values of blood pressure corresponding to grade 3 hypertension. In France, until 2011, the social security also included in the definition of severe HTA chronic situations characterized by moderate blood pressure values requiring at least triple anthihypertensive therapies associated with a clinical or infraclinical target organ damages. These clinical profiles, much more frequent than grade 3 hypertension, allowed the full reimbursement of care costs for these patients. In France, it is estimated that 10% of hypertensive patients present a severe form with an annual incidence of 50,000 patients. The patients with severe hypertension have an increased cardiovascular morbidity justifying a closer clinical monitoring. From an economic point of view, these severe forms of hypertension have a higher cost of care, explained primarily by a more frequent need of specialized referrals, radiological exams and hospitalizations. This excess cost justified the existence of a full coverage of induced costs by the social security, since the incidence of severe hypertension is more frequent in the low social categories, and in patients with economic fragility.

    The discovery of a receptor for vitamin D in most cells suggested a role in other body systems, not only the impact on the body's calcium economy. Epidemiological studies found that lower levels of cholecalciferol coexists with cardiovascular diseases. The aim of the study was to evaluate the factors influencing the serum concentration of vitamin in the population of the region of Cracow and to assess and compare the rate of consumption of food products rich in vitamin D in patients with hypertension and with normal blood pressure. In the studied population, the higher the age of the subjects, and the later the month of the year the sample was taken, the lower the vitamin D serum concentrations. Low body mass index and body fat were associated with higher levels of cholecalciferol. Additionally, deficiency of vitamin D was caused by insufficient supply of food products rich in cholecalciferol. PMID:27526422

    The evaluation of causes of hypertension in young adults with a family history of hypertension needs to be methodical to identify potentially treatable causes. Renal- and renovascular imaging and measurement of plasma aldosterone and plasma renin activity are at the core of this evaluation in most patients. Pertinent aspects of hypertension in autosomal dominant polycystic kidney disease are discussed with a focus on the role of the endothelium in mediating early hypertension and a review of treatment strategies. Finally, the possibility that autosomal dominant polycystic kidney disease and primary aldosteronism are connected beyond coincidence is explored; evidence to support it is scant, although there is a likely role for aldosterone excess and the resultant hypokalemia in promoting cyst growth.

    Among patients with resistant hypertension (RHTN), there are those whose blood pressure (BP) remains uncontrolled in spite of maximal medical therapy. This retrospective analysis aims to characterize these patients with refractory hypertension. Refractory hypertension was defined as BP that remained uncontrolled after ≥3 visits to a hypertension clinic within a minimum 6-month follow-up period. Of the 304 patients referred for RHTN, 29 (9.5%) remained refractory to treatment. Patients with refractory hypertension and those with controlled RHTN had similar aldosterone levels and plasma renin activity (PRA). Patients with refractory hypertension had higher baseline BP (175±23/97±15 mm Hg vs 158±25/89±15 mm Hg; P=.001/.005) and heart rate, and higher rates of prior stroke and congestive heart failure. During follow-up, the BP of patients with refractory hypertension remained uncontrolled (168.4±14.8/93.8±17.7 mm Hg) in spite of use of an average of 6 antihypertensive medications, while those of patients with controlled RHTN decreased to 129.3±11.2/77.6±10.8 mm Hg. Spironolactone reduced the BP by 12.9±17.8/6.6±13.7 mm Hg in patients with refractory hypertension and by 24.1±16.7/9.2±12.0 mm Hg in patients with controlled RHTN. In patients with RHTN, approximately 10% remain refractory to treatment. Similar aldosterone and PRA levels and a diminished response to spironolactone suggest that aldosterone excess does not explain the treatment failure.

    Arterial hypertension is a serious and common complication of cyclosporine administration in humans. The prevalence of arterial hypertension in patients following orthotopic heart transplantation ranges from 38% to 92%. There are several characteristic features of this form of hypertension, including very early onset--usually within 4 to 6 weeks after transplantation and persistence with little alteration overtime. Diurnal profile shows the lack of normal nocturnal decline in blood pressure (BP) and appearance of the highest values of BP early in the morning. This phenomenon is caused by altered regulation of BP due to cardiac denervation. There was shown no correlation between the dose of cyclosporine and development of posttransplant arterial hypertension. It develops also independently of many investigated pretransplant and posttransplant cardiovascular risk factors. A great deal of attention has been focused on explantation of cyclosporine influence leading to hypertension occurrence. suggested mechanisms of this action are: elevation of systemic vascular resistance, prostaglandines and tromboxance production imbalance, hypomagnesemia, increased intravascular volume, modulation of sympathetic activity, nephrotoxicity. Reninangiotensin system seems to be not significantly associated with posttransplant hypertension, whereas the role of corticosteroides is still controversal. Hypertension remains the most common complication associated with cyclosporine administration in heart transplant recipients. Mechanisms of cyclosporine action leading to development of hypertension are still unknown. Further investigation is also needed into clinical significance of posttransplant hypertension and its influence on long-term survival after heart transplantation as they remain undefined.

    A 75-year-old patient comes to a community pharmacy to refill her blood pressure (BP) medications. She approached the pharmacist complaining of a headache and an unusually high BP reading that she had gotten from the automated machine. The patient was unaware of her usual BP, but knew that the reading was unusually high for her. Following evaluation of the patient and after obtaining several high systolic BP readings, the pharmacist appropriately calls for an ambulance. At the hospital, the patient is told she is in need of triple-bypass surgery. After her hospital stay, the patient is now diligent about refilling her BP medications on time and consistently monitors and records her BP at home. Isolated systolic hypertension is a growing concern in older adults, and a large percentage of adults are not appropriately managed. Pharmacists play an active role in educating patients on the importance of high BP monitoring and adherence to minimize the risk of cardiovascular events. PMID:20534408

    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

    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

    In this study we aimed to investigate the risk factors associated with arterial hypertension and diabetes mellitus in young adults assisted in six Family Health Units (UBASF), of Fortaleza, Ceará, Brazil. This is a descriptive and documental study, based on the records of the Care Program to Arterial Hypertension and Diabetes Mellitus (HIPERDIA). The sample was composed of 60 records, including hypertensive, diabetics and patients with the two diagnoses. The results showed prevalence of young female adults (78%). Regarding the risk factors, arterial hypertension (n=45), family history (n=33), overweight (n=33) and sedentary lifestyle (n=27) stood out. Regarding the cardiovascular risk stratification, most presented Medium additional risk for cardiovascular disease. We concluded that the individualized evaluation of risk factors supports an action addressed for possible events, being necessary investments in prevention and also in training and maintenance of the HIPERDIA system.

    Our objective was to gain a better understanding of minority patients’ beliefs about hypertension and to use this understanding to develop a model to explain gaps in communication between patients and clinicians. Eighty-eight hypertensive Black and Latino adults from four inner-city primary care clinics participated in focus groups to elucidate views on hypertension. Participants believed that hypertension was a serious illness in need of treatment. Participants’ diverged from the medical model in their beliefs about the time-course of hypertension (believed hypertension was intermittent); causes of hypertension (believed stress, racism, pollution, and poverty were the important causes); symptoms of hypertension (believed hypertension was primarily present when symptomatic); and treatments for hypertension (preferred alternative treatments that reduced stress over prescription medications). Participants distrusted clinicians who prioritized medications that did not directly address their understanding of the causes or symptoms of hypertension. Patients’ models of understanding chronic asymptomatic illnesses such as hypertension challenge the legitimacy of lifelong, pill-centered treatment. Listening to patients’ beliefs about hypertension may increase trust, improve communication, and encourage better self-management of hypertension. PMID:22235822

    We performed a national survey to determine the prevalence, awareness, treatment and control of hypertension, one of the main cardiovascular risk factors, among the adult population in Tunisia. A total of 8007 adults aged 35-70 years were included in the study. Blood pressure (BP) measurements were taken by physicians with a mercury sphygmomanometer, and standard interviewing procedures were used to record medical history, socio-demographic and cardiovascular disease (CVD) risk factors. Hypertension was defined as a systolic BP ≥140 mm Hg and/or diastolic BP ≥90 mm Hg or current treatment with antihypertensive drugs. The prevalence of hypertension was 30.6%, higher in women (33.5%) than in men (27.3%). Multiple logistic regression analyses identified a higher age, urban area, higher body mass index, type 2 diabetes and family history of CVD as important correlates to the prevalence of hypertension. Only 38.8% of those with hypertension were aware of their diagnosis, of which 84.8% were receiving treatment. BP control was achieved in only 24.1% of treated hypertensive persons. Women were more aware than men (44.8 vs. 28.8%), but the rates of treatment and control of hypertension did not differ between the two genders. Higher age, being female, lower education level and urban area emerged as important correlates of hypertension awareness. The study highlights the hypertension problem in a middle-income developing country. There is an urgent need for a comprehensive integrated population-based intervention program to ameliorate the growing problem of hypertension in Tunisians.

    Objectives Our study aimed to estimate the rate of white coat hypertension (WCH) and effect, and masked hypertension in patients attending a tertiary care hospital for 24 hour ambulatory blood pressure monitoring (24-h ABPM). Methods A total of 231 adult patients were referred to the Department of Clinical Physiology at Sultan Qaboos University Hospital, Muscat, for ABPM, between January 2010 and June 2012. The following data were gathered and analyzed: demographic data, clinic blood pressure (BP) measurements, and 24-h BP profile from ABPM. Thirty-two patients were excluded and the final analysis included 199 patients. Results There were 105 (52.8%) women and 94 (47.2%) men studied. The mean age of patients was 46±15 years and most patients were overweight with a mean BMI of 29.6±5kg/m2. Around half of patients (53.8%) were on one or more antihypertensive medications. WCH was found in 10.6% and white coat effect was found in 16% of patients. The majority of patients (57%) with WCH were aged 40 years or above. Masked hypertension was present in 6% of patients and masked uncontrolled hypertension in 8.5% of patients. Conclusions Our study showed that WCH and effect, and masked hypertension are common in hypertensive patients. Identifying these patients will have an impact on their management. However, the results of the study should be interpreted within the context of its limitations. Prospective randomized community and hospital-based studies should be conducted to estimate the true prevalence in the general population as well as in hypertensive patients. PMID:25960832

    The characteristics of pulmonary arterial hypertension (PAH), including pathology, symptoms, diagnosis and treatment are reviewed in children and adults. The histopathology seen in adults is also observed in children, although children have more medial hypertrophy at presentation. Both populations have vascular and endothelial dysfunction. Several unique disease states are present in children, as lung growth abnormalities contribute to pulmonary hypertension. Although both children and adults present at diagnosis with elevations in pulmonary vascular resistance and pulmonary artery pressure, children have less heart failure. Dyspnoea on exertion is the most frequent symptom in children and adults with PAH, but heart failure with oedema occurs more frequently in adults. However, in idiopathic PAH, syncope is more common in children. Haemodynamic assessment remains the gold standard for diagnosis, but the definition of vasoreactivity in adults may not apply to young children. Targeted PAH therapies approved for adults are associated with clinically meaningful effects in paediatric observational studies; children now survive as long as adults with current treatment guidelines. In conclusion, there are more similarities than differences in the characteristics of PAH in children and adults, resulting in guidelines recommending similar diagnostic and therapeutic algorithms in children (based on expert opinion) and adults (evidence-based).

    It has been estimated that approximately 11% of the US adult population has chronic kidney disease (CKD), and it has been demonstrated that the prevalence of hypertension rises significantly as renal function declines. Even mild CKD significantly increases mortality risk, and cardiovascular disease remains the main cause of death among these patients. Although CKD patients have generally been excluded from trials testing the effect of lowering blood pressure on cardiovascular outcomes, guidelines suggest lowering blood pressure in hopes of reducing cardiovascular mortality and slowing the progression of renal disease. The preferred antihypertensive agents among these patients are drugs that block the renin-angiotensin system. In most hypertensive CKD patients, however, multiple agents are necessary to reach blood pressure targets. In general, diuretics and calcium channel blockers are added subsequently as adjunctive therapy. Hopefully, with increased recognition of the unique aspects of treating hypertension in this population, end-stage renal disease and cardiovascular morbidity and mortality will be delayed or avoided in the millions of patients with CKD.

    OBJECTIVE: Choices of pharmacologic therapies for pulmonary arterial hypertension (PAH) are ideally guided by high-level evidence. The objective of this guideline is to provide clinicians advice regarding pharmacologic therapy for adult patients with PAH as informed by available evidence. METHODS: This guideline was based on systematic reviews of English language evidence published between 1990 and November 2013, identified using the MEDLINE and Cochrane Library databases. The strength of available evidence was graded using the Grades of Recommendations, Assessment, Development, and Evaluation methodology. Guideline recommendations, or consensus statements when available evidence was insufficient to support recommendations, were developed using a modified Delphi technique to achieve consensus. RESULTS: Available evidence is limited in its ability to support high-level recommendations. Therefore, we drafted consensus statements to address many clinical questions regarding pharmacotherapy for patients with PAH. A total of 79 recommendations or consensus statements were adopted and graded. CONCLUSIONS: Clinical decisions regarding pharmacotherapy for PAH should be guided by high-level recommendations when sufficient evidence is available. Absent higher level evidence, consensus statements based upon available information must be used. Further studies are needed to address the gaps in available knowledge regarding optimal pharmacotherapy for PAH. PMID:24937180

    Prenatal exposure to glucocorticoids (GCs) programs for hypertension later in life. The aim of the current study was to examine the impact of prenatal GC exposure on the postnatal regulation of the gene encoding for phenylethanolamine N-methyltransferase (PNMT), the enzyme involved in the biosynthesis of the catecholamine, epinephrine. PNMT has been linked to hypertension and is elevated in animal models of hypertension. Male offspring of Wistar-Kyoto dams treated with dexamethasone (DEX) developed elevated systolic, diastolic and mean arterial blood pressure compared to saline-treated controls. Plasma epinephrine levels were also elevated in adult rats exposed to DEX in utero. RT-PCR analysis revealed adrenal PNMT mRNA was higher in DEX exposed adult rats. This was associated with increased mRNA levels of transcriptional regulators of the PNMT gene: Egr-1, AP-2, and GR. Western blot analyses showed increased expression of PNMT protein, along with increased Egr-1 and GR in adult rats exposed to DEX in utero. Furthermore, gel mobility shift assays showed increased binding of Egr-1 and GR to DNA. These results suggest that increased PNMT gene expression via altered transcriptional activity is a possible mechanism by which prenatal exposure to elevated levels of GCs may program for hypertension later in life.

    Nutritional recommendations constitute a major aspect of the long term management of coronary and hypertensive patients, for which the established evidence is more and more solid. The benefits are not limited solely to the impact on weight and lipid parameters. In coronary patients, besides the reduction in saturated fatty acids, which is always indicated, an increase in the intake of omega-3 fatty acids is associated with a significant reduction in morbidity and mortality, notably with sudden death. Intake of folates is also beneficial, as well as fruit and vegetable consumption. These elements are constituents of alimentary models such as the mediterranean diet. In hypertensives, weight reduction, limitation of alcohol and sodium intake, and increasing potassium and magnesium intakes have a demonstrable effect. Evaluation of patient compliance to nutritional recommendations is just as important as that of compliance to treatments and control of classic risk factors.

    We aimed to determine a possible association between isolated morning hypertension (IMH) and meal-induced blood pressure (BP) fall in adult treated hypertensive patients who underwent home BP measurements. A total of 230 patients were included, median age 73.6, 65.2% women. After adjusting for age, sex, number of antihypertensive drugs, office and home BP levels, the association between IMH and meal-induced BP fall was statistically significant. In conclusion, meal-induced BP fall and IMH detected through home blood pressure monitoring (HBPM) are independently associated in hypertensive patients. The therapeutic implications of such observation need to be clarified in large-scale prospective studies.

    Hypertension is common, difficult to diagnose, and poorly controlled among patients with ESRD. However, controversy surrounds the diagnosis and treatment of hypertension. Here, we describe the diagnosis, epidemiology, and management of hypertension in dialysis patients, and examine the data sparking debate over appropriate methods for diagnosing and treating hypertension. Furthermore, we consider the issues uniquely related to hypertension in pediatric dialysis patients. Future clinical trials designed to clarify the controversial results discussed here should lead to the implementation of diagnostic and therapeutic techniques that improve long-term cardiovascular outcomes in patients with ESRD.

The study was based on the fifth Korean National Health and Nutrition Examination Survey between 2010 and 2011. A total of 9221 Korean adults aged ≥19 years were studied. Fried food consumption was assessed using a validated FFQ. Metabolic risk factors such as waist circumference, fasting plasma glucose (FPG), TAG, HDL-cholesterol and systolic and diastolic blood pressure (SBP and DBP) were measured. Hypertension was defined as SBP≥140 mmHg, DBP≥90 mmHg or current use of antihypertensive medication. Adjusted OR for elevated blood pressure significantly increased in men (OR 1·62; 95% CI 1·11, 2·37; P(trend)=0·0447) and women (OR 2·20; 95% CI 1·21, 4·00; P(trend)=0·0403) with a greater than twice a week consumption of fried food compared with those who rarely consumed fried food. However, fried food consumption was not associated with other metabolic risk factors (abdominal obesity, high FPG, hypertriacylglycerolaemia, low HDL-cholesterol and the metabolic syndrome). The adjusted OR for hypertension increased by 2·4-fold in women (OR 2·37; 95% CI 1·19, 4·72; P(trend)=0·0272) with a greater than twice a week fried food consumption compared with those who rarely consumed it. No significant association was found between fried food consumption and hypertension in men. This study suggests that frequent fried food consumption is associated with hypertension in Korean women. Further studies are needed to investigate the effect of different types of fried foods on hypertension.

    Background The prevalence of hypertension is rising worldwide with an estimated one billion people now affected globally and is of near epidemic proportions in many parts of South Asia. Recent turmoil has until recently precluded estimates in Afghanistan so we sought, therefore, to establish both prevalence predictors in our population. Methods We conducted a cross-sectional study of adults ≥40 years of age in Kabul from December 2011-March 2012 using a multistage sampling method. Additional data on socioeconomic and lifestyle factors were collected as well as an estimate of glycaemic control. Bivariate and multivariable analyses were undertaken to explore the association between hypertension and potential predictors. Results A total of 1183 adults (men 396, women 787) of ≥ 40years of age were assessed. The prevalence of hypertension was 46.2% (95% CI 43.5 – 49.3). Independent predictors of hypertension were found to be: age ≥50 (OR = 3.86, 95% CI: 2.86 – 5.21); illiteracy (OR = 1.90, 1.05 – 1.90); the consumption of rice >3 times per week (OR = 1.43, 1.07 – 1.91); family history of diabetes (OR = 2.20, 1.30 – 3.75); central obesity (OR = 1.67, 1.23 – 2.27); BMI ≥ 30 Kg/meter squared (OR = 2.08, 1.50 – 2.89). The consumption of chicken and fruit more than three times per week were protective with ORs respectively of 0.73 (0.55-0.97) and 0.64 (0.47 – 0.86). Conclusions Hypertension is a major public health problem in Afghan adults. We have identified a number of predictors which have potential for guiding interventions. PMID:24754870

    This study was undertaken to determine whether perinatal maternal resveratrol (Resv)--a phytoalexin known to confer cardiovascular protection--could prevent the development of hypertension and improve vascular function in adult spontaneously hypertensive rat offspring. Dams were fed either a control or Resv-supplemented diet (4 g/kg diet) from gestational day 0.5 until postnatal day 21. Indwelling catheters were used to assess blood pressure and vascular function in vivo; wire myography was used to assess vascular reactivity ex vivo. Perinatal Resv supplementation in dams had no effect on fetal body weights, albeit continued maternal treatment postnatally resulted in growth restriction in offspring by postnatal day 21; growth restriction was no longer evident after 5 weeks of age. Maternal perinatal Resv supplementation prevented the onset of hypertension in adult offspring (-18 mm Hg; P=0.007), and nitric oxide synthase inhibition (with L-NG-nitroarginine methyl ester) normalized these blood pressure differences, suggesting improved nitric oxide bioavailability underlies the hemodynamic alterations in the Resv-treated offspring. In vivo and ex vivo, vascular responses to methylcholine were not different between treatment groups, but prior treatment with L-NG-nitroarginine methyl ester attenuated the vasodilation in untreated, but not Resv-treated adult offspring, suggesting a shift toward nitric oxide-independent vascular control mechanisms in the treated group. Finally, bioconversion of the inactive precursor big endothelin-1 to active endothelin-1 in isolated mesenteric arteries was reduced in Resv-treated offspring (-28%; P<0.05), and this difference could be normalized by L-NG-nitroarginine methyl ester treatment. In conclusion, perinatal maternal Resv supplementation mitigated the development of hypertension and causes persistent alterations in vascular responsiveness in spontaneously hypertensive rats.

    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.

    Hypertension is increasingly common in sub-Saharan Africa, and rates of hypertension control are low. Use of traditional herbal medicines (THM) is common among adults in sub-Saharan Africa and may affect hypertension therapy. We searched Ovid MEDLINE, Ovid EMBASE, and Web of Knowledge in June 2013 to find studies about THM use among hypertensive patients living in sub-Saharan Africa. Two independent reviewers evaluated titles and abstracts. Qualifying references were reviewed in full text. Data were extracted using a standardized questionnaire. Four hundred and eighty-one references were retrieved, and four articles from two countries met criteria for inclusion. The prevalence of THM use was 25-65% (average 38.6%). THM was the most common type of complementary and alternative medicines used by patients (86.7-96.6%). Among THM users, 47.5% concomitantly used both allopathic medicine and THM. Increased age (p<0.001), male sex (RR 2.58), belief in a supernatural cause of hypertension (RR 2.11), and family history of hypertension (OR 1.78) were positively associated with THM use, while belief that hypertension is preventable was negatively associated with THM use (OR 0.57). More than one-third of adults with hypertension in sub-Saharan Africa use THM. Half of these patients use THM concurrently with allopathic medicine. Healthcare workers in sub-Saharan Africa must discuss THM use with their hypertensive patients. More research is urgently needed to define the impact of THM use on hypertension control and outcomes in sub-Saharan Africa. PMID:24764197

    Lacunar infarcts in non-hypertensive patients have been scantly assessed. The objective of this study was to determine clinical features of lacunar infarct in patients without hypertension (n = 91) in comparison with characteristics of lacunar infarcts occurring in patients with hypertension (n = 283) collected from a prospective hospital-based stroke registry in which 2000 patients with acute stroke are included. Predictors of lacunar infarct in patients without hypertension were assessed by multiple logistic regression analysis. The group of non-hypertensive patients with lacunar infarction showed a significantly higher frequency of male gender, age 85 years or older, history of atrial fibrillation, chronic obstructive pulmonary disease and diabetes mellitus, and a significantly lower frequency of female gender and absence of limitation at hospital discharge than hypertensive patients with lacunar infarct. Differences between hypertensive and non-hypertensive patients in relation to frequency of the different lacunar syndromes were not observed. After multivariate analysis, age 85 years or older (odds ratio 3.13), diabetes (odds ratio 2.57), and male gender (odds ratio 1.99) seemed to be independent factors associated with lacunar infarct in patients without hypertension. Lacunar infarct in non-hypertensive patients showed some differential clinical features compared to the remaining lacunar infarctions because it occurred more frequently in male patients aged 85 years or older. In this group, diabetes was the most important modifiable risk factor. These results suggest an earlier effect of arteriopathy caused by hypertension favoring lacunar brain ischemia, whereas in non-hypertensive patients, arteriopathy responsible for small vessel disease would take a more prolonged time in causing lacunar infarction.

    The aim of this study is to describe trends in the awareness, treatment, and control of hypertension; mean blood pressure; and the classification of blood pressure among US adults 2003 to 2012. Using data from the National Health and Nutrition Examination Survey 2003 to 2012, a total of 9255 adult participants aged ≥18 years were identified as having hypertension, defined as measured blood pressure ≥140/90 mm Hg or taking prescription medication for hypertension. Awareness and treatment among hypertensive adults were ascertained via an interviewer administered questionnaire. Controlled hypertension among hypertensive adults was defined as systolic blood pressure <140 mm Hg and diastolic blood pressure <90 mm Hg. Blood pressure was categorized as optimal blood pressure, prehypertension, and stage I and stage II hypertension. Between 2003 and 2012, the percentage of adults with controlled hypertension increased (P-trend <0.01). Hypertensive adults with optimal blood pressure and with prehypertension increased from 13% to 19% and 27% to 33%, respectively (P-trend <0.01 for both groups). Among hypertensive adults who were taking antihypertensive medication, uncontrolled hypertension decreased from 38% to 30% (P-trend <0.01). Similarly, a decrease in mean systolic blood pressure was observed (P-trend <0.01); however, mean diastolic blood pressure remained unchanged. The trend in the control of blood pressure has improved among hypertensive adults resulting in a higher percentage with blood pressure at the optimal or prehypertension level and a lower percentage in stage I and stage II hypertension. Overall, mean systolic blood pressure decreased as did the prevalence of uncontrolled hypertension among the treated hypertensive population.

    For the first time, the Canadian Hypertension Education Program has studied the evidence supporting blood pressure control in people requiring renal replacement therapy for end-stage kidney disease, including those on dialysis and with renal transplants. According to the Canadian Organ Replacement Registry’s 2008 annual report, there were an estimated 33,832 people with end-stage renal disease in Canada at the end of 2006, an increase of 69.7% since 1997. Of these, 20,465 were on dialysis and 13,367 were living with a functioning kidney transplant. Thus, it is becoming more likely that primary care practitioners will be helping to care for these complex patients. With the lack of large controlled clinical trials, the consensus recommendation based on interpretation of the existing literature is that blood pressure should be lowered to below 140/90 mmHg in hypertensive patients on renal replacement therapy and to below 130/80 mmHg for renal transplant patients with diabetes or chronic kidney disease.

    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

    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.

    Hyper-homocysteinemia (HHcy) is associated with microalbuminuria and glomerular injury in general and diabetic populations. However, HHcy’s role in hypertensive patients was not studied. We investigated whether HHcy is an independent risk factor for renal function decline and development of chronic kidney disease (CKD) in hypertensive men and women. This was a community-based prospective cohort study of 2,387 hypertensive adults without CKD at baseline, with a mean follow-up of 4.4 years. Baseline and follow-up levels of plasma Hcy, folate, vitamin B12, blood pressure and other pertinent covariables were obtained. CKD was defined as an estimated glomerular filtration rate (eGFR) <60 ml/min/per 1.73 m2 and an eGFR decline rate >1 ml/min/per 1.73 m2/year. There was a graded association between Hcy tertiles and eGFR decline. Subjects in the 3rd tertile of Hcy levels had an accelerated rate of eGFR decline and an increased risk of incident CKD, as compared with those in the 1st tertile, after adjusting for age, gender, baseline diabetes, SBP, BMI, smoking, dyslipidemia, eGFR, folate and vitamin B12 levels. In conclusion, in this prospective cohort of Chinese hypertensive adults, elevated baseline plasma Hcy can serve as an independent biomarker to predict renal function decline and incident CKD.

    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.

    Hypertension is a key risk factor for cardiovascular disease, and new treatments are needed. Uric acid reduction lowers blood pressure (BP) in adolescents, suggesting a direct pathophysiological role in the development of hypertension. Whether the same relationship is present in older adults is unknown. We explored change in BP after allopurinol initiation using data from the UK Clinical Practice Research Datalink. Data were extracted for patients with hypertension aged >65 years who were prescribed allopurinol with pretreatment and during treatment BP readings. Data from comparable controls were extracted. The change in BP in patients with stable BP medication was the primary outcome and was compared between groups. Regression analysis was used to adjust for potential confounding factors, and a propensity-matched sample was generated. Three hundred sixty-five patients who received allopurinol and 6678 controls were included. BP fell in the allopurinol group compared with controls (between-group difference in systolic and diastolic BP: 2.1 mm Hg; 95% confidence interval, -0.6 to 4.8; and 1.7 mm Hg; 95% confidence interval, 0.4-3.1, respectively). Allopurinol use was independently associated with a fall in both systolic and diastolic BP on regression analysis (P<0.001). Results were consistent in the propensity-matched sample. There was a trend toward greater fall in BP in the high-dose allopurinol group, but change in BP was not related to baseline uric acid level. Allopurinol use is associated with a small fall in BP in adults. Further studies of the effect of high-dose allopurinol in adults with hypertension are needed.

    A 63-year-old man was admitted to our hospital for further investigation and management of brain metastases. The patient was initially presented with a 4-day history of confusion. On the day of admission, the patient was confused, agitated, disorientated in place and time, and had visual disturbances. His blood pressure was repeatedly recorded high, with levels of systolic blood pressure between 170-210 mm Hg. A brain magnetic resonance imaging showed areas of high signal on T2 and fluid-attenuated inversion recovery images, located bilaterally in the white matter of the occipital regions and unilateral in the left frontal lobe, suggestive of posterior reversible encephalopathy syndrome. Aggressive treatment of hypertension resulted in complete resolution of the clinical and radiologic features of the syndrome. PMID:26896240

    Corazón Sano y Feliz is a hypertension management intervention developed to address deficiencies in the management of hypertensive patients in Guatemala. From 2007 to 2009, Corazón Sano y Feliz was pilot-tested in the community of Mixco. Corazón Sano y Feliz comprises a clinical risk assessment and treatment component implemented primarily by nurses, and a health education component implemented by community health workers. To accomplish our secondary objective of determining Corazon Sano y Feliz's potential for change at the patient level, we implemented a one-group pretest-posttest study design to examine changes in clinical measures, knowledge and practices between baseline and the end of the 6-month intervention. Two nurses and one physician set up a hypertension clinic to manage patients according to risk level. Twenty-nine community health workers were trained in CVD risk reduction and health promotion and in turn led six educational sessions for patients. Comparing baseline and 6-month measures, the intervention achieved significant improvements in mean knowledge and behaviour (increase from 54.6 to 59.1 out of a possible 70 points) and significant reductions of mean systolic and diastolic blood pressure (27.2 and 7.7 mmHg), body mass index (from 26.5 to 26.2 kg/m(2)) and waist circumference (89.6-88.9 cm). In this pilot study we obtained preliminary evidence that this community-oriented hypertension management and health promotion intervention model was feasible and achieved significant reduction in risk factors. If scaled up, this intervention has the potential to substantially reduce CVD burden.

    Antiplatelet therapy (AT) is indicated in hypertensive patients with increased cardiovascular risk. The literature about the adequate or inadequate prescription of AT is scarce. We conducted a prospective descriptive study to quantify therapeutic inertia and non-guideline-recommended prescription (NGRP) of AT (aspirinor clopidogrel or both), and to assess associated factors, calculating the adjusted odds ratios (ORs) from multivariate models. In 2007-2009, 712 primary health-care hypertensive patients in a Spanish region were enrolled. Inertia was defined as the lack of an AT prescription, despite being indicated by guidelines, whereas NGRP was defined as AT prescription when there was no guideline recommendation. We also recorded cardiovascular variables. Inertia and NGRP were quantified for primary and secondary prevention. Of 108 patients in secondary prevention, 53 had inertia (49.1%, 95% confidence interval (CI): 39.6-58.5%). Associated profile: female (OR=0.460, P=0.091), no dyslipidemia (OR=0.393, P=0.048), no coronary heart disease (OR=0.215, P=0.001) and high diastolic blood pressure (OR=1.076, P=0.016). In primary prevention, NGRP was present in 69 of 595 patients (11.6%, 95% CI: 9.0-14.2%). Associated profile: male (OR=1.610, P=0.089), smoking (OR=2.055, P=0.045), dyslipidemia (OR=3.227, P<0.001) and diabetes (OR=2.795, P<0.001).

    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.

    Cardiac arrhythmias were studied in patients with essential hypertension in relation to their myocardial function. It was found that the arrhythmias occurring in the early period of the disease (borderline hypertension, Stage I hypertension) were primarily functional and affected the course of the disease and hemodynamics to a small degree. The life-threatening arrhythmias recorded in early hypertension were more commonly caused by mitral prolapse. The duration and severity of hypertension, development of left ventricular myocardial hypertrophy, myocardial fiber distension in relative heart failure play a decisive role in the development of cardiac arrhythmias in patients with Stage II hypertensive disease. It is essential to make comprehensive clinical and instrumental studies to clarify the genesis of the arrhythmic syndrome and to correctly choose the management policy in these patients.

    Hypertension is a predominant risk factor for cardiovascular diseases and a major health care burden. Accumulating epidemiological and experimental evidence suggest that adult-onset hypertension may have its origins during early development. Upon exposure to glucocorticoids, the fetus develops hypertension, and the offspring may be programmed to continue the hypertensive trajectory into adulthood. Elevated oxidative stress and deranged nitric oxide system are not only hallmarks of adult hypertension but are also observed earlier in life. Endothelial dysfunction and remodeling of the vasculature, which are robustly associated with increased incidence of hypertension, are likely to have been pre-programmed during fetal life. Apparently, genomic, non-genomic, and epigenomic factors play a significant role in the development of hypertension, including glucocorticoid-driven effects on blood pressure. In this review, we discuss the involvement of the aforementioned participants in the pathophysiology of hypertension and suggest therapeutic opportunities for targeting epigenome modifiers, potentially for personalized medicine.

    Background/Objectives: Effective prevention of cardiovascular events in people with hypertension requires optimal control of blood pressure. Despite advances in management, poor adherence to antihypertensive medications is often reported as the major reason attenuating treatment efficacy. Research has provided limited evidence of associations between illness perceptions, satisfaction with consultations, and medication adherence. The aim of this study is to identify factors significantly associated with medication adherence in a group of Chinese older adults with essential hypertension. Design/Setting/Participants: A cross-sectional correlational study was conducted. Data were collected from 195 older adults (mean [SD] age, 76 [6.6] years) recruited from 12 community centers. Measurements: The Illness Perception Questionnaire–Revised was used to measure illness perceptions, and the Medical Interview Satisfaction Scale was used to measure satisfaction with individual consultations. The Morisky Medication Adherence Scale was used to measure the extent of adherence to antihypertensive medications. Multivariate logistic regression analysis was performed to examine factors, including illness perceptions, consultation satisfaction, and demographic and clinical characteristics, that were significantly associated with medication adherence. Results: More than half of the respondents (55.9%) acknowledged some degree of medication nonadherence. Older age, living alone, and perception related to treatment control were independently associated with increased odds of medication adherence, with odds ratios ranging from 1.14 to 1.92 (P < .05). Conclusion: The results highlight the importance of cultivating positive beliefs that hypertension is amenable to control by treatment. Furthermore, the adherence behavior of those of younger individuals and living with family should be closely monitored. PMID:25774846

    The beneficial effect of antihypertensive medication on reducing the risk of cardiovascular disease (CVD) events is supported by data from randomized controlled trials of older adults with hypertension. However, in clinical practice, overtreatment of hypertension in older adults may lead to side effects and an increased risk of falls. The diagnosis and treatment of hypertension is primarily based on blood pressure measurements obtained in the clinic setting. Ambulatory blood pressure monitoring (ABPM) complements clinic blood pressure by measuring blood pressure in the out-of-clinic setting. ABPM can be used to identify white coat hypertension, defined as elevated clinic blood pressure and non-elevated ambulatory blood pressure. White coat hypertension is common in older adults but does not appear to be associated with an increased risk of CVD events among this population. Herein, we review the current literature on ABPM in the diagnoses of white coat hypertension in older adults, including its potential role in preventing overtreatment.

    Background The links between obstructive sleep apnoea and hypertension are well established; obstructive sleep apnoea is reported in up to 30% of patients with hypertension, although it is frequently underdiagnosed. Physicians can assess the degree of sleepiness by administering the Epworth Sleepiness Scale, but the large number of patients with hypertension makes this strategy difficult for busy physicians to implement. Obese patients form a subgroup at higher risk for obstructive sleep apnoea, which can be targeted for screening. Aim The study carried out a preliminary exploration of the effectiveness of screening patients with hypertension and obesity for obstructive sleep apnoea in general practice using the Epworth Sleepiness Scale. Setting One group practice in Italy. Design of study ‘Good clinical practice’ was systematically applied: identification of patients with hypertension and obesity; qualitative interview to identify obstructive sleep apnea; and consequent work-up and therapy. Method Three family physicians, caring for 769 pharmacologically-treated patients with hypertension, identified 220 obese patients without relevant pulmonary or neurological diseases or insomnia; 31 of these 220 patients scored >11 on the Epworth Sleepiness Scale. Results Polysomnography confirmed obstructive sleep apnoea in 10% of the obese, hypertensive population (95% confidence interval [CI] = 7.03% to 13.63%), and in 3.9% of the whole hypertensive population (95% CI = 2.74% to 5.51%). At baseline, 24-hour blood pressure monitoring showed uncontrolled blood pressure in all these patients. Under continuous positive airway pressure (CPAP), the blood pressure value normalised (P<0.05), and the mean Epworth Sleepiness Scale score decreased significantly: mean 13.68 versus 7.84 (P<0.001). Conclusion In obese patients with hypertension examined in this study, the prevalence of obstructive sleep apnoea prevalence is about 10%. CPAP significantly ameliorates the blood pressure

    Hypertension is a leading risk factor in the global disease burden. Limited hypertension awareness is a major determinant of widespread gaps in hypertension treatment and control, especially in developing countries. We analyzed data on persons aged 50 years or older from 6 low- and middle-income countries participating in the first wave (2007-2010) of the World Health Organization's Survey of Global Ageing and Adult Health (SAGE). Our estimates suggest that just 1 year of routine opportunistic hypertension screening during formal visits to medical-care providers could yield significant increases in hypertension awareness among seniors in the developing world. We also show that eliminating missed opportunities for hypertension screening in medical settings would not necessarily exacerbate existing socioeconomic differences in hypertension awareness, despite requiring at least occasional contact with a formal health-care provider for obtaining a hypertension diagnosis. Thus, routine opportunistic screening for hypertension in formal medical settings may provide a simple but reliable way to increase hypertension awareness. Moreover, the proposed approach has the added advantage of leveraging existing resources and infrastructures, as well as facilitating a direct transition from the point of diagnosis to subsequent expert counseling and clinical care for newly identified hypertension patients.

    The incidence of hypertension was sought in 102 children who had undergone renal transplantation. Fifty five were being treated with cyclosporin and 47 with azathioprine, and they were followed up for a maximum of five years. After one year 35 of those receiving cyclosporin (64%) and 34 of those receiving azathioprine (72%) were hypertensive; after five years the figures were 5/6 (83%) and 25/35 (71%), respectively. Recipients of grafts from living related donors had a lower incidence of hypertension than recipients of cadaveric grafts. The incidence of hypertension was higher in patients with acquired original kidney disease than in children with congenital or familial diseases. In both groups creatinine clearance and the frequency of acute rejection episodes did not differ between normotensive and hypertensive patients. When the lowest concentrations of cyclosporin in whole blood were more than 400 ng/ml the incidence of hypertension one year after transplantation was higher. The incidence of hypertension after renal transplantation in children is higher than that reported in adults. Acquired original disease, transplantation of cadaveric grafts, and nephrotoxicity of cyclosporin are all contributory factors. PMID:2334203

    Background Hypertension control is a challenge globally. Barriers to optimal control exist at the patient, physician, and health system levels. Patient-related barriers in our environment are not clear. The aim of this study was to identify patient-related barriers to control of hypertension among adults with hypertension in a semiurban community in South-East Nigeria. Methods This was a cross-sectional descriptive study of patients with a diagnosis of hypertension and on antihypertensive medication. Results A total of 252 participants were included in the survey, and comprised 143 males (56.7%) and 109 females (43.3%). The mean age of the participants was 56.6±12.7 years, with a diagnosis of hypertension for a mean duration of 6.1±3.3 years. Among these patients, 32.9% had controlled blood pressure, while 39.3% and 27.8%, respectively, had stage 1 and stage 2 hypertension according to the Seventh Report of the Joint National Committee on Prevention, Detection and Evaluation of High Blood Pressure. Only 23.4% knew the consequences of poor blood pressure control and 64% were expecting a cure from treatment even when the cause of hypertension was not known. Furthermore, 68.7% showed low adherence to medication, the reported reasons for which included forgetfulness (61.2%), financial constraints (56.6%), high pill burden (22.5%), side effects of medication (17.3%), and low measured blood pressure (12.1%). Finally, knowledge and practice of the lifestyle modifications necessary for blood pressure control was inadequate among the participants. Conclusion Poor knowledge regarding hypertension, unrealistic expectations of treatment, poor adherence with medication, unawareness of lifestyle modification, and failure to apply these were identified as patient-related barriers to blood pressure control in this study.

    Objectives This study used high-resolution 3-dimensional cardiac magnetic resonance to define the anatomical and functional left ventricular (LV) properties associated with increasing systolic blood pressure (SBP) in a drug-naïve cohort. Background LV hypertrophy and remodeling occur in response to hemodynamic stress but little is known about how these phenotypic changes are initiated in the general population. Methods In this study, 1,258 volunteers (54% women, mean age 40.6 ± 12.8 years) without self-reported cardiovascular disease underwent 3-dimensional cardiac magnetic resonance combined with computational modeling. The relationship between SBP and wall thickness (WT), relative WT, end-systolic wall stress (WS), and fractional wall thickening were analyzed using 3-dimensional regression models adjusted for body surface area, sex, race, age, and multiple testing. Significantly associated points in the LV model (p < 0.05) were identified and the relationship with SBP reported as mean β coefficients. Results There was a continuous relationship between SBP and asymmetric concentric hypertrophic adaptation of the septum and anterior wall that was associated with normalization of wall stress. In the lateral wall an increase in wall stress with rising SBP was not balanced by a commensurate hypertrophic relationship. In normotensives, SBP was positively associated with WT (β = 0.09) and relative WT (β = 0.07) in the septal and anterior walls, and this regional hypertrophic relationship was progressively stronger among pre-hypertensives (β = 0.10) and hypertensives (β = 0.30). Conclusions These findings show that the precursors of the hypertensive heart phenotype can be traced to healthy normotensive adults and that an independent and continuous relationship exists between adverse LV remodeling and SBP in a low-risk population. These adaptations show distinct regional variations with concentric hypertrophy of the septum and eccentric hypertrophy of the

    Objectives This study examines links between early life circumstances and adult socioeconomic status and obesity and hypertension in the adult Mexican population. Methods We use data from the Mexican Family Life Survey (MxFLS) collected in 2002 for people aged 20 or older (N=14, 280). Results We found that men with low education and women with more education have significantly lower obesity. Women with higher education also have significantly less hypertension. Obesity triples the likelihood of hypertension among both men and women. Better childhood experiences are associated with less hypertension among women, but more hypertension among men in rural areas. Discussion Recent changes in income, nutrition, and infection in Mexico may be responsible for the observed high prevalence of overweight and obesity and the extremely high odds of hypertension among obese young adults.

    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.

    Abstract This study aimed to estimate the relationship between various lipid abnormalities and albuminuria in hypertensive Korean adults. Data obtained from the Korea National Health and Nutrition Examination Survey in 2011 to 2012 were analyzed. The study included 2330 hypertensive participants. Total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) levels were measured. Dyslipidemia parameters were defined as high TG ≥200 mg/dL, low HDL-C as HDL-C <40 mg/dL, high TC/HDL-C as TC/HDL-C ratio ≥4, high TG/HDL-C as TG/HDL-C ratio ≥3.8, and high LDL-C/HDL-C as LDL-C/HDL-C ratio ≥2.5. Albuminuria was defined as a urine albumin to creatinine ratio (ACR) ≥30 mg/g. Women with albuminuria showed significantly higher levels of TG, TC/HDL-C, and TG/HDL-C and a lower level of HDL-C than women without albuminuria (all P < 0.05). LogTG, TC/HDL-C, and logTG/HDL-C were positively correlated with ACR in both men and women; however, HDL-C was negatively correlated with ACR in women and non-HDL-C was positively correlated with ACR in men. In men, there was no association between ACR and lipid parameters. However, in women, higher values for logTG, TC/HDL-C, and logTG/HDL-C were associated with an increased odds ratio (OR) for albuminuria (OR [95% confidence interval]: 1.53 [1.06–2.21], 1.21 [1.02–1.45], and 1.78 [1.21–2.63], respectively) and HDL-C with a decreased OR for albuminuria (0.78 [0.67–0.92]) after adjusting for all covariates. LogTG, TC/HDL-C, and logTG/HDL-C were associated with an increased prevalence of albuminuria in hypertensive women. Screening and treatment for dyslipidemia may be necessary for hypertensive women to address potential albuminuria. PMID:27100412

    The concomitant presence of systemic arterial hypertension and chronic obstructive pulmonary disease (COPD) is frequent. Indeed, arterial hypertension is the most common comorbid disease in COPD patients. Since many antihypertensive drugs can act on airway function the treatment of arterial hypertension in COPD patients appears complex. Moreover, in these patients, a combined therapy is required for the adequate control of blood pressure. Currently, available data are inconsistent and not always comparable. Therefore the aim of this review is to analyze how antihypertensive drugs can affect airway function in order to improve the clinical management of hypertensive patients with COPD. Thiazide diuretics and calcium channel blockers appear the first-choice pharmacological treatment for these patients.

    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

    Hypertension is one of the most common chronic diseases affecting more than 25% of adults worldwide. In Pakistan, 33% of the adult population suffers from hypertension. Numerous epidemiological studies have demonstrated the critical role of dietary patterns in the causation, prevention and management of hypertension. There's a dearth of evidence from South Asia in this regard. The present study aimed to identify the association between dietary patterns and hypertension among 4304 low income urban adults who participated in the Control of Blood Pressure and Risk Attenuation (COBRA) study in Karachi, Pakistan. Dietary information was collected by a 33- item food frequency questionnaire and 3 unique dietary patterns namely; fat and sweet, fruit and vegetable, and seafood and yogurt patterns were derived using principal component factor analyses. We used univariate and multivariable logistic regression to examine the association between dietary patterns and hypertension. Men were more likely to have hypertension, while increase in age, and body mass index were also associated with hypertension (p<0.001). After adjusting for age, gender, education, marital status, body mass index, and tobacco use; the seafood and yogurt pattern was less likely (OR=0.78: 95% CI: 0.63, 0.98; p-value 0.03) to be associated with hypertension, whereas no significant associations were seen for other two dietary patterns. These findings suggest that certain dietary patterns may be associated with hypertension among Pakistani low income urban adults. PMID:26693757

    OBJECTIVES To describe sodium-related knowledge and self-reported behaviors in adults with hypertension and assess the association between knowledge and behaviors and blood pressure levels in this population. METHODS Using convenience sampling of patients with hypertension, an oral cross-sectional survey was administered by student pharmacists in 45 community pharmacies in Alabama and Florida in May to July 2012. After survey questions were administered, patients' blood pressures were measured. Data were tested for significance at alpha < 0.05 using bivariate analyses of independent and dependent variables (systolic/diastolic blood pressure [SBP/DBP]) and parallel linear regression of significant independent variables. RESULTS The majority of the 664 patients surveyed were women (59.3%) and white (75.2%). Most resided in urban areas (81.5%). The mean SBP/DBP was 133.3 (SD = 15.7)/81.7 (SD = 9.1) mg Hg. Most participants recognized the relationship between salt intake and high blood pressure (91.1%) and stroke (78.0%). A small percentage of patients reported that they always look for sodium content on food products (15.0%) and always buy low-sodium products (10.6%). Patients with lower knowledge scores (B = -0.01, P < 0.001) and those who were advised to cut down on salt (B = 0.02, P = 0.037) had higher SBP levels when controlled for gender, race, and awareness of their blood pressure goals. In regression analysis, lower knowledge scores were associated with increased DBP levels (B = -0.52, P = 0.014) when controlled for gender and race. CONCLUSION Many patients were not aware of salt in processed food and did not always look for sodium content on nutritional labels. Pharmacists should address dietary salt when interacting with patients with hypertension. PMID:24562633

A cross-sectional survey was conducted in 5 cities of urban areas and 5 counties of rural areas in Southern China in 2013, a stratified multistage random sampling method was used to select a representative sample. Recruitment included a total of 19254 participants aged 15 or older. Socio-demographic profiles, examinations were administrated on each subject. Multilevel logistic regression models were used to identify the risk factors of hypertension, awareness, treatment, and control. Overall, the prevalence of hypertension and pre-hypertension are 24.59% and 32.11%, respectively in southern China. Among all the hypertensive patients, 67.43% were aware of their condition, 55.76% took anti-hypertension medication recent two weeks, and 30.79% had their blood pressure controlled. Compared with male, female hypertensive patients had higher rates of hypertension awareness, treatment and control. Age, gender, marital status, living areas, education, BMI, waist circumference, visceral adipose index (VAI), high body fat percentage (BFP) and family hypertension history correlated with the prevalence of hypertension. SBP/DBP increased with VAI and BFP increasing. There is an increasing prevalence of hypertension and high pre-hypertension in the general population in southern China, but levels of awareness, treatment, and control remain relatively low, especially for young and middle-aged population. Innovative strategies including of adopting appropriate anti-hypertensive medication therapy and healthy lifestyles should be taken. PMID:26784948

    [Purpose] This study was performed to determine whether certain lifestyle factors are associated with hypertension in community-dwelling Korean adults. [Subjects and Methods] The subjects were 586 males and 1,135 females > 20 years old who had visited a public health promotion center in Seoul, Republic of Korea to take a survey related to lifestyle factors. Hypertension status was defined according to the criteria of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure VII report. [Results] The relationships between lifestyle factors and hypertension status were assessed using multivariate logistic regression analysis after adjusting for age and gender. Only mental stress and economic status significantly predicted hypertension status. [Conclusion] We conclude that sleep duration, education level, frequency of drinking and smoking status were not associated with hypertension status. However, economic status and mental stress were significantly associated with hypertension in community-dwelling Korean adults, regardless of age or gender. PMID:26834333

    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

    The aim of this study descriptive study was to evaluate concordance with medication and those factors that affect the use of medicine in patients with hypertension. Data were collected using a questionnaire completed by 750 patients with hypertension between December 25, 2003, and April 30, 2004, in an outpatient hypertension clinic in Erzincan, Turkey. It was found that 57.9% of the patients did not use their medicines as prescribed. Forgetfulness, aloneness, and negligence were ranked as the top three reasons for this non-concordance, accounting for almost half (49.3%) of all patients with hypertension studied; price (expensive medicines) accounted for another quarter (26.5%). A statistically significant relationship with non-concordance was found for age, education level and profession. Patients' lack of knowledge related to the complications of hypertension was also found to have a statistically significant relationship with not taking medicines as prescribed. Gender, location of residence and salary were not found to be statistically related to concordance. These results indicate the need to educate patients with hypertension on how to use their medicine regularly and indicate also the target populations for this. PMID:23127428

    Patients with pulmonary hypertension are at increased risk for perioperative morbidity and mortality. Elective surgery is generally discouraged in this patient population; however, there are times when surgery is deemed necessary. Currently, there are no guidelines for the preoperative risk assessment or perioperative management of subjects with pulmonary hypertension. The majority of the literature evaluating perioperative risk factors and mortality rates is observational and includes subjects with multiple etiologies of pulmonary hypertension. Subjects with pulmonary arterial hypertension, also referred to as World Health Organization group I pulmonary hypertension, and particularly those receiving pulmonary arterial hypertension-specific therapy may be at increased risk. Perioperative management of these patients requires a solid understanding and careful consideration of the hemodynamic effects of anesthetic agents, positive pressure ventilation and volume shifts associated with surgery in order to prevent acute right ventricular failure. We reviewed the most recent data regarding perioperative morbidity and mortality for subjects with pulmonary hypertension in an effort to better guide preoperative risk assessment and perioperative management by a multidisciplinary team.

    Evidence suggests that coronary heart disease (CHD) is the most common outcome of hypertension. Hypertension accelerates the development of atherosclerosis, and sustained elevation of blood pressure (BP) can destabilize vascular lesions and precipitate acute coronary events. Hypertension can cause myocardial ischemia in the absence of CHD. These cardiovascular risks attributed to hypertension can be reduced by optimal BP control. Although several antihypertensive agents exist, the choice of agent and the appropriate target BP for patients with CHD remain controversial. In this succinct paper, we examine the evidence and the mechanisms for the linkage between hypertension and CHD and we discuss the treatment options and the goals of therapy that are consistent with the report of the seventh Joint National Committee on the Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC 7) and American Heart Association scientific statement. We anticipate changes in the recommendations of the forthcoming JNC 8. PMID:21785704

    In patients with type 2 diabetes, the prevalence of hypertension is higher than in non-diabetic subjects. Despite the high cardiovascular risk involving hypertension in these patients, its prevalence and control are not well known. The aims of this study were: to estimate the hypertension prevalence, awareness, treatment and control in Spanish adults with type 2 diabetes attended in Primary Care; and to analyse its time trend from 2003 to 2009. A serial cross-sectional study from 2003 to 2009 was performed in 21 Primary Care Centres in Madrid. The study population comprised all patients with diagnosed type 2 diabetes in their computerised medical history. Overall annual prevalence during the period 2003–2009 was calculated from and according to sex and age groups. Linear trend tests, regression lines and coefficients of determination were used. In 2003 89.78% (CI 87.92–91.64) of patients with type 2 diabetes suffered hypertension and 94.76% (CI: 92.85–96.67) in 2009. This percentage was greater for women and for patients over 65 years old. 30% of patients suffered previously undiagnosed hypertension in 2003 and 23.1% in 2009. 97% of diagnosed patients received pharmacological treatment and 28.79% reached the blood pressure objective in 2009. The average number of antihypertensive drugs taken was 2.72 in 2003 and 3.27 in 2009. Only 5.2% of patients with type 2 diabetes show blood pressure levels below 130/80 mmHg. Although significant improvements have been achieved in the diagnosis and control of hypertension in people with type 2 diabetes, these continue to remain far from optimum. PMID:24475171

    Background The prevalence of pulmonary hypertension is unusually high in Taiwanese patients with end-stage renal disease. Thrombosis of hemodialysis grafts is common and pulmonary embolism has been reported after endovascular thrombectomy. The aim of this study was to evaluate the relationship between pulmonary hypertension and endovascular thrombectomy of hemodialysis grafts. Methods One hundred and ten patients on hemodialysis via arteriovenous grafts were enrolled in our study. The mean pulmonary artery pressure (PAP) was measured by right heart catheterization. Clinical information was collected by review of medical records. Comorbid cardiopulmonary disease was evaluated by echocardiography and chest X-ray. The history of patient vascular access thrombosis was reviewed from database, hemodialysis records, and interviews with staff at hemodialysis centers. Results Fifty-two participants (47%) had pulmonary hypertension diagnosed by right heart catheterization. There was no difference in the number of thrombectomy procedures between patients with and without pulmonary hypertension. Based on multivariate analysis, the number of prior endovascular thrombectomy procedures did not correlate with mean PAP (F-value = 1.10, p = 0.30) nor was it associated with pulmonary hypertension (odds ratio = 0.92, p = 0.17). Conclusions Prior endovascular arteriovenous graft thrombectomies were not associated with pulmonary hypertension or increased mean PAP in end-stage renal disease patients on maintenance hemodialysis.

    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.

    Background: Hypertension is commonly found in patients with Diabetic Kidney Disease (DKD). Microalbuminuria is the first clinical sign of involvement of kidneys in patients with type 2 diabetes. Uncontrolled hypertension induces a higher risk of cardiovascular events, including death, increasing proteinuria and progression to kidney disease. Objectives: To determine the correlation between microalbuminuria and hypertension and their association with other risk factors in type 2 diabetic patients. Methods: One hundred and thirteen type 2 diabetic patients attending the diabetic clinic of Shaikh Zayed Postgraduate Medical Institute, Lahore, Pakistan were screened for microalbuminuria and raised blood pressure. The study was conducted from November 2012 to June 2013. Results: Patients were divided into two groups. Group 1, those with normoalbuminuria (n=63) and Group 2, those having microalbuminuria (n=50). Group 2 patients showed higher blood pressure values as compared to Group 1. The results were statistically significant and showed poor glycemic control as a contributing risk factor. Conclusion: The study concluded that there is high frequency of hypertension among type 2 diabetics but still much higher among those having microalbuminuria. So, early recognition of renal dysfunction through detection of microalbuminuria and to start treatment without any delay will confer future protection from end stage renal disease as well as hypertension and its complications in type 2 diabetic patients.

    Pulmonary hypertension remains a challenging condition to diagnose and manage. Decentralized care for pulmonary arterial hypertension (PAH) has led to shortcomings in the diagnosis and management of PAH. The Pulmonary Hypertension Association-sponsored Pulmonary Hypertension Care Center program is designed to recognize specialty centers capable of providing multidisciplinary and comprehensive care of PAH. Ideally, Pulmonary Hypertension Care Centers will comanage PAH patients with community-based practitioners and address the growing needs of this emerging population of long-term PAH patients.

    Obesity is a major health problem in the United States, and the burden associated is high. Hypertension seems to be the most common obesity-related health problem. Studies show that hypertension is approximately twice as prevalent among the obese as in the non-obese population. This study has two main objectives. First, to examine the association between obesity and hypertension within the context of economic growth in Appalachia, and second to estimate the cost of hypertension linked to obesity in Appalachia. The study uses simultaneous equations and Logit analysis for estimations. Data are from Behavior Risk Factor Surveillance Systems (BRFSS) surveys of 2001 and 2009. Results for simultaneous analysis show that hypertension decreases with decreasing obesity, increasing employment growth, and increasing income. Logit analysis highlights the importance of controlling obesity, income growth, employment growth, education, and exercises in mitigating hypertension in Appalachia. Ageing indicates a high potential of getting hypertension. Total economic cost of hypertension linked to obesity is $9.35 billion, significantly a high cost to Appalachia. Overall, results reveal the impacts of obesity on hypertension and some possible ways of mitigation. Thus, results suggest a comprehensive set of policies to Appalachia which sufficiently improve employment opportunities, educational facilities, and healthcare facilities with adequately addressed to obesity and hypertension.

  19. Ambulatory Blood Pressure Monitoring (ABPM) as the reference standard for diagnosis of hypertension and assessment of vascular risk in adults.

    New information has become available since the ISC, AAMCC, and SECAC released their first extensive guidedelines to improve the diagnosis and treatment of adult arterial hypertension. A critical assessment of evidence and a comparison of what international guidelines now propose are the basis for the following statements, which update the recommendations first issued in 2013. Office blood pressure (BP) measurements should no longer be considered to be the "gold standard" for the diagnosis of hypertension and assessment of cardiovascular risk. Relying on office BP, even when supplemented with at-home wake-time self-measurements, to identify high-risk individuals, disregarding circadian BP patterning and asleep BP level, leads to potential misclassification of 50% of all evaluated persons. Accordingly, ambulatory BP monitoring is the recommended reference standard for the diagnosis of true hypertension and accurate assessment of cardiovascular risk in all adults ≥18 yrs of age, regardless of whether office BP is normal or elevated. Asleep systolic BP mean is the most significant independent predictor of cardiovascular events. The sleep-time relative SBP decline adds prognostic value to the statistical model that already includes the asleep systolic BP mean and corrected for relevant confounding variables. Accordingly, the asleep systolic BP mean is the recommended protocol to diagnose hypertension, assess cardiovascular risk, and predict cardiovascular event-free interval. In men, and in the absence of compelling clinical conditions, reference thresholds for diagnosing hypertension are 120/70 mmHg for the asleep systolic/diastolic BP means derived from ambulatory BP monitoring. However, in women, in the absence of complicating co-morbidities, the same thresholds are lower by 10/5 mmHg, i.e., 110/65 mmHg for the asleep means. In high-risk patients, including those diagnosed with diabetes or chronic kidney disease, and/or those having experienced past

    OBJECTIVE: to identify the prevalence of arterial hypertension and its association with cardiovascular risk factors among adults. METHOD: cross-sectional, population-based, descriptive study conducted with 408 adult individuals. Data were collected through a questionnaire and measurements of weight, height and waist circumference. Person's Chi-square and multiple logistic regression were used in the data analysis. RESULTS: 23.03% of the individuals reported hypertension with a higher prevalence among women. Odds Ratio indicated that smoking, body mass index, waist circumference, diabetes mellitus and dyslipidemia were positively associated with arterial hypertension. CONCLUSION: high self-reported hypertension and its association with other cardiovascular risk factors such as diabetes, obesity and dyslipidemia show the need for specific nursing interventions and the implementation of protocols focused on minimizing complications arising from hypertension, as well as to prevent the emergence of other cardiovascular diseases.

    OBJECTIVE: To determine whether there is any influence of systemic arterial hypertension on the peripheral auditory system. METHODS: This was a cross-sectional study that investigated 40 individuals between 30 and 50 years old, who were divided into groups with and without systemic arterial hypertension, using data from high-frequency audiometry, transient-evoked otoacoustic emissions and distortion-product otoacoustic emissions. The results were compared with those from groups of normal-hearing individuals, with and without systemic arterial hypertension, who underwent the pure-tone audiometry test. All individuals also underwent the following procedures: otoscopy, acoustic immittance measures, pure-tone audiometry at frequencies from 250 to 16000 Hz, transient-evoked otoacoustic emissions test and distortion-product otoacoustic emissions test. RESULTS: No statistically significant difference was observed between the groups with and without systemic arterial hypertension in either conventional or high-frequency audiometry. Regarding transient-evoked otoacoustic emissions, there was a trend toward statistical significance whereby the systemic arterial hypertension group showed lower results. Regarding distortion-product otoacoustic emissions, the systemic arterial hypertension group showed significantly lower results at the following frequencies: 1501, 2002, and 3003 Hz. A discriminant analysis indicated that the distortion-product otoacoustic emissions variables best distinguished individuals with and without systemic arterial hypertension. CONCLUSION: Data from this study suggest cochlear dysfunction in individuals with systemic arterial hypertension because their otoacoustic emission results were lower than those in the systemic arterial hypertension group.

    Background: Microalbuminuria in hypertension has been described as an early sign of kidney damage and a predictor for end stage renal disease and cardiovascular disease. Thus, it is of great importance to study urinary albumin creatinine ratio and progression of kidney disease in hypertensive patients. Aims: The present study was undertaken to find out the prevalence and association of microalbuminuria in newly diagnosed essential hypertension. Materials and Methods: Newly diagnosed essential hypertensive cases (n = 106) and normotensive controls (n = 106) were enrolled. Hypertension was defined according to Joint national committee-VII definitions. Microalbuminuria was measured using an U-Albumin (NycoCard, Norway) and adjusted for urine creatinine. Descriptive statistics and testing of hypothesis were used for the analysis using SPSS 16 software. Results: 51.88% of hypertension cases and 13.2% of normotensive controls had microalbuminuria in total population (odds ratio 7.086, P-value <0.001). 46.67% of cases and 12.08% of controls had microalbuminuria in male population (odds ratio 6.375, P-value <0.001). Similarly, 58.7% of cases and 14.58% of controls had microalbuminuria in female population (odds ratio 8.32, P-value <0.001). Conclusions: By showing strong association between microalbuminuria and hypertension, our findings suggest that microalbuminuria could be a useful marker to assess risk management of cardiovascular disease and renal disease.

    Exaggerated pressor and muscle sympathetic nerve activity (MSNA) responses have been reported during static handgrip in hypertensive (HTN) adults. Recent work suggests that such responses may occur much more rapidly in HTN patients; however, this has not been extensively studied. Thus, we examined the blood pressure (BP) and MSNA responses at the immediate onset of muscle contraction and tested the hypothesis that older HTN adults would exhibit rapid onset pressor and sympathetic responses compared with normotensive (NTN) adults. Heart rate (HR), BP (Finometer) and MSNA (peroneal microneurography) were retrospectively analyzed in 15 HTN (62 ± 1 years; resting BP 153 ± 3/91 ± 5 mm Hg) and 23 age-matched NTN (60 ± 1 years; resting BP 112 ± 1/67 ± 2 mm Hg) subjects during the first 30 s of static handgrip at 30 and 40% of maximal voluntary contraction (MVC). HTN adults demonstrated exaggerated increases in mean BP during the first 10 s of both 30% (NTN: Δ1 ± 1 vs HTN: Δ7 ± 2 mm Hg; P < 0.05) and 40% (NTN: Δ2 ± 1 vs HTN: Δ8 ± 2 mm Hg; P < 0.05) intensity handgrip. Likewise, HTN adults exhibited atypical increases in MSNA within 10 s. Increases in HR were also greater in HTN adults at 10 s of 30% MVC handgrip, although not at 40% MVC. There were no group differences in 10 s pressor or sympathetic responses to a cold pressor test, suggesting no differences in generalized sympathetic responsiveness. Thus, static handgrip evokes rapid onset pressor and sympathetic responses in older HTN adults. These findings suggest that older HTN adults likely have greater cardiovascular risk even during short duration activities of daily living that contain an isometric component. PMID:25471615

    Few studies have investigated patients with pulmonary hypertension and arrhythmias. Data on electrophysiological studies in these patients are rare. In a retrospective dual-centre design, we analysed data from patients with indications for electrophysiological study. Fifty-five patients with pulmonary hypertension were included (Dana Point Classification: group 1: 14, group 2: 23, group 3: 4, group 4: 8, group 5: 2, and 4 patients with exercised-induced pulmonary hypertension). Clinical data, 6-minute walk distance, laboratory values, and echocardiography were collected/performed. Nonsustained ventricular tachycardia was the most frequent indication (n = 15) for an electrophysiological study, followed by atrial flutter (n = 14). In summary 36 ablations were performed and 25 of them were successful (atrial flutter 12 of 14 and atrioventricular nodal reentrant tachycardia 4 of 4). Fluoroscopy time was 16 ± 14.4 minutes. Electrophysiological studies in patients with pulmonary hypertension are feasible and safe. Ablation procedures are as effective in these patients as in non-PAH patients with atrial flutter and atrioventricular nodal reentrant tachycardia and should be performed likewise. The prognostic relevance of ventricular stimulations and inducible ventricular tachycardias in these patients is still unclear and requires further investigation.

    Platelets may be activated in hypertension (HT). Hypertensive crisis is an extreme phenotype of HT and HT-related thrombotic complications. We aimed to assess mean platelet volume (MPV) in patients with hypertensive crises. This study included 215 hypertensive urgency (HU) patients (84 male, mean age = 66 ± 15 years) and 60 hypertensive emergency (HE) patients (26 male, mean age = 68 ± 13 years), who were admitted to the emergency department with a diagnosis of hypertensive crises. Control group was composed of age- and sex-matched 39 normotensive patients. Blood samples were withdrawn for whole blood count and routine biochemical tests. Systolic blood pressure (BP) was significantly higher in the HE group than in the HU group (p < 0.001). Median mean platelet volume (MPV) was higher in the HE group compared with HU and control groups [9.5 (Interquartile range, IQR: 8.7-10.1), 8.4 (IQR: 7.7-9.1), and 8.3 (IQR: 7.7-8.7) fl, each p < 0.001, respectively). In linear regression analysis, systolic BP (β = 0.18, 95% confidence intervals (CI): 0.002-0.015, p = 0.007) and diabetes mellitus (β = 0.24, 95% CI: 0.28-0.95, p < 0.001) were independently associated with MPV levels. Our findings show that MPV can be elevated in patients with HE and HU. It can be independently associated with systolic BP and diabetes mellitus. These findings imply that platelet activation contribute to the pathogenesis of thrombotic complications in hypertensive crises.

    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

    Cerebral hyperperfusion, anemia and hypertension are common in patients with end-stage renal disease (ESRD). Young ESRD adults might afford a better hemodynamic tolerance; however, their cerebral vascular disorders are often overlooked. This phase-contrast MRI study investigated relationships between cerebral blood flow (CBF), anemia and hypertension in young adults undergoing hemodialysis (HD). Blood flows, velocities, and cross-sectional areas of bilateral internal carotid arteries and vertebral arteries were quantified on phase maps in 33 patients and 27 healthy controls. Cerebral oxygen delivery (COD) and vascular resistance were (CVR) were computed based on CBF, hemoglobin and mean arterial pressure (MAP). We found strong correlations among hemoglobin, MAP and CBF. Hemoglobin rather than MAP was directly related to CBF. COD was negatively related to MAP, while CVR was positively related to hemoglobin. The cross-sectional areas of arteries were increased which were directly associated with hemoglobin rather than MAP. HD patients were of elevated CBF, decreased COD and unchanged CVR. Although elevated CBF compensated anemia-induced hypoxia, COD of these patients was still lower. Anemia directly contributed to elevated CBF and hypertension affected CBF through anemia. Unaffected CVR of young patients probably indicated that they could maintain basic functions of cerebral circulation under multiple risk factors. PMID:26923866

    Type 2 diabetes mellitus (T2DM) and hypertension represent two common conditions worldwide. Their frequent association with cardiovascular diseases makes management of hypertensive patients with T2DM an important clinical priority. Carvedilol and renal denervation are two promising choices to reduce plasma glucose levels and blood pressure in hypertensive patients with T2DM to reduce future complications and improve clinical outcomes and prognosis. Pathophysiological mechanisms of both options are under investigation, but one of the most accepted is an attenuation in sympathetic nervous system activity which lowers blood pressure and improves insulin sensitivity. Choice of these therapeutic approaches should be individualized based on specific characteristics of each patient. Further investigations are needed to determine when to consider their use in clinical practice. PMID:25126399

    Hypertension is the first and the most common risk factor to diseases such as cardiovascular, stroke, and renal diseases. The aim of this study was to determine the factors relevant to hypertension knowledge, treatment, and control in southern Iran. In this cross-sectional study, conducted in Kohgiluye Boyer-Ahmad province, south of Iran, a total of 1836 hypertension patients were randomly selected to participate voluntarily in the study. Hypertension treatment and its control were defined during study. In addition, knowledge about hypertension was measured by hypertension knowledge level scale (HK-LS). Treatment rates were 75.5 and 37.7 percent for female and male, respectively. Habitat, education, income, family history with hypertension, smoking, and time of diagnosis to the disease were found to be related to the treatment of the disease. Control rates were 30.7 and 31.4 for males and females, respectively. Habitat, education, and time of diagnosis to the disease were related to control. Over 50 percent of patients had average knowledge on hypertension. Considering the low rate of control and knowledge on hypertension among patients, health care providers should reinforce their services to improve appropriate knowledge level among elders and, also, plan comprehensive programs to promote health in order to encourage patients change and reform their life style.

    The dramatic change of the natural history of HIV-infected patients by highly active antiretroviral therapy (HAART) has exposed these patients to cardiovascular risk, including cardiovascular disease and hypertension. In HIV-infected patients, the development of arterial hypertension, at least in the medium-long term is an established feature, although recognized predictors of its development have not been clearly identified. In addition, conflicting data regarding the influence of antiretroviral therapy (ART) are reported. The presence of a proinflammatory state and oxidative stress-mediated endothelial dysfunction seem, however, to play a pathophysiologic role. In this review, we examine and provide a comprehensive, literature based, consideration of the pathophysiologic aspects of hypertension in these patients. HIV-infected patients, independently of the presence of hypertension, remain at very high cardiovascular risk due to the presence of the same cardiovascular risk factors recognized for the general population with, in addition, the indirect influence of the ART, essentially via its effect on lipid metabolism. This review based on the evidence from the literature, concludes that the management of HIV-infected patients in terms of cardiovascular prevention emerges as a priority. The consideration of cardiovascular risk in these patients should receive the same emphasis given for the general population at high cardiovascular risk, including adequate blood pressure control according to international guidelines.

    The purpose of this study was to investigate the application of trial balloon occlusion for permanent closure of patent ductus arteriosus (PDA) with severe pulmonary hypertension (PH) in adults, and to assess its immediate and short-term results. From September 1999 to September 2005, a total of ten adults (two males, ages ranging from 20 to 54 years) with PDA who met the criterion for severe PH (basal pulmonary vascular resistance >8 Wood units) received trial balloon occlusion via an embolectomy balloon catheter. Post-occlusion hemodynamics, along with an overall clinical and hemodynamic assessment, was used to consider the indication of closure of PDA. Nine of the patients underwent successful transcatheter closure of PDA and subsequently used Amplatzer occluder devices. Chest X-ray, cardiography and echocardiography were used for follow-up evaluation of the treatment within 6 months after successful closure of PDA. No patient had a detectable residual shunt by color flow mapping or any other complications (device migration, hemolysis, endocarditis, etc.) at follow-up. In conclusion, trial balloon occlusion helps to determine anticipated hemodynamics after closure of PDA, so it is conducive to indicating permanent closure of adult PDA with reversible but severe PH. Furthermore, satisfactory immediate and short-term outcomes have proven this method to be safe and valid. (Hypertens Res 2008; 31: 1997-2002).

    Hypertension is one of the commonest diseases worldwide. Hypertension (HTN) or high blood pressure, sometimes called arterial hypertension, is a chronic medical condition, which elevated blood pressure in the arteries. This forces the heart to work harder than normal to circulate blood via the blood vessels. Blood pressure is summarized by two measurements, systolic and diastolic, which depend on between beats (diastole). Normal blood pressure at rest is within the range of 100-140 mmHg systolic (top reading) high blood pressure is said to be present if it is persistently at or above 140/90 mmHg of cases are categorized as primary hypertension that means high blood pressure with no obvious underlying medical cause. Updated studies reported associations between depressive symptoms and hypertensive patients. Depression may be an independent diagnosis, it is also possible that depressive symptoms are secondary to chronic illnesses and their associated complex medication regimens, regardless of the diagnosis being primary or secondary, prior reports have demonstrated that depressive symptoms are associated with inadequate blood pressure control and complications of hypertension.

    We evaluated the prevalence, awareness, treatment and control of hypertension in Korean adults with diagnosed diabetes using nationally representative data. Among subjects aged ≥30 years who participated in the Fourth Korea National Health and Nutrition Examination Survey in 2007 and 2008, a total of 745 subjects (336 men and 409 women) with a previous diagnosis of diabetes mellitus were analyzed. The prevalence of hypertension in adults with diagnosed diabetes was 55.5%. The rates of awareness, treatment and control were 88.0, 94.2, and 30.8%, respectively. Compared with the general population, the prevalence of hypertension in adults with diagnosed diabetes was higher in all age groups in both genders. Factors independently associated with a high prevalence of hypertension included being male, increasing age, single, <9 years of education, the presence of chronic kidney disease risk, hypercholesterolemia (≥240 mg dl(-1)) and high body mass index (≥25 kg m(-2)). Regular medical screening was positively associated with hypertension control, whereas a high triglyceride level (≥150 mg dl(-1)) was inversely associated. A high prevalence and a low control rate of hypertension in adults with diagnosed diabetes suggest that stringent efforts are needed to control blood pressure in diabetic patients.

    Background Hypertension is a major health problem throughout the world and is one of the major risk factors for cardiovascular mortality. It is important to detect and manage prehypertension and hypertension to reduce the risk of correlated complications especially cardiovascular diseases. Objective The objective of the study was to find the prevalence and risk factors of hypertension among the adults in rural Nepal. Method A community based cross-sectional study was conducted among 648 respondents. The information was obtained using pre-tested questionnaire which included demographic information of individuals and other risk factors like alcohol and tobacco use, physical activity and diet preference. Height, weight and blood pressure were recorded and hypertension was defined as per Joint National Committee (JNC) VII guidelines. Result The overall prevalence of hypertension was 20.5 % and pre-hypertension was 46.6%. The males had higher prevalence of hypertension (30.6%) compared to females (13.8%). Bivariate analysis showed male gender, smoking and non vegetarian diet have association with hypertension. Male gender [OR 2.50 (1.68 - 3.74)] and non vegetarian diet [OR 0.11 (0.01 - 0.85)] were found to be significantly associated with hypertension in multivariate analysis. Conclusion The prevalence of hypertension and prehypertension was high in the study population. In absence of life style modification and risk reduction the individuals categorized as prehypertension have great risk of developing hypertension in the future which may pose a great challenge in the future. Hence, there is a big scope for screening and primary prevention strategies to curb the epidemic of hypertension. PMID:27423286

    Systemic arterial hypertension (SAH) has a prevalence of approximately 1 billion cases worldwide. The main goals for its treatment involve changes in a patient's lifestyle, with a strategy of management that aims to increase his or her level of physical activity, with a recommendation for aerobic and resistance exercise. Some evidence has suggested that training with isometric exercises can produce effects similar to aerobic exercise on blood pressure reduction. Conventional exercises that are currently used in rehabilitation of hypertensive patients show low adherence, with a lack of motivation on the part of those patients. In that context, the Pilates method, which uses isometric exercises, has been gaining in popularity and worldwide acceptance, and it has the potential to be an effective method. The current literature review shows the possible benefits of the Pilates method for rehabilitation of hypertensive patients. However, even though the method is a promising modality, the authors have found that future research appears to be necessary to evaluate the benefits of Pilates for hypertensive patients.

    Background: Dichlorodiphenyltrichloroethane (DDT) was used extensively to control malaria, typhus, body lice, and bubonic plague worldwide, until countries began restricting its use in the 1970s. However, the use of DDT to control vector-borne diseases continues in developing countries. Prenatal DDT exposure is associated with elevated blood pressure in humans. Objective: We hypothesized that perinatal DDT exposure causes hypertension in adult mice. Methods: DDT was administered to C57BL/6J dams from gestational day 11.5 to postnatal day 5. Blood pressure (BP) and myocardial wall thickness were measured in male and female adult offspring. Adult mice were treated with an angiotensin converting enzyme (ACE) inhibitor, captopril, to evaluate sensitivity to amelioration of DDT-associated hypertension by ACE inhibition. We further assessed the influence of DDT exposure on the expression of mRNAs that regulate BP through renal ion transport. Results: Adult mice perinatally exposed to DDT exhibited chronically increased systolic BP, increased myocardial wall thickness, and elevated expression of mRNAs of several renal ion transporters. Captopril completely reversed hypertension in mice perinatally exposed to DDT. Conclusions: These data demonstrate that perinatal exposure to DDT causes hypertension and cardiac hypertrophy in adult offspring. A key mechanism underpinning this hypertension is an overactivated renin angiotensin system because ACE inhibition reverses the hypertension induced by perinatal DDT exposure.

    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.

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

    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.

    In spite of the extensive research efforts that have been conducted over the last decades, it is still very difficult to point out genetic determinants or environmental conditions responsible for the development of essential hypertension. We searched for differences in the RBC membrane skeleton structure and O2 membrane permeability between RBCs from patients with both essential arterial hypertension and hypercholesterolemia, from patients having only hypercholesterolemia and from healthy donors. The topography of RBCs and the content of various hemoglobin forms were detected using atomic force microscopy and Mössbauer spectroscopy, respectively. We found that the membrane skeleton of RBCs from healthy donors displayed a well-known honeycomb pattern, whereas in patients with essential hypertension and/or hypercholesterolemia, who had never received anti-hypertensive therapy, it displayed a corncob pattern. Hypertensive RBCs had an oval shape and the average lateral to longitudinal diameter ratio for the changed cells (about 70%) did not exceed 0.80. We observed that after the incubation of RBCs under high nitrogen (low O2) pressure at room temperature and then their transfer into 85 K, a content of oxyHb (deoxyHbOH) already after 1 h reached a stable level of about 85 ± 3% (15 ± 3%) in hypertensives, whereas in healthy individuals it showed a decrease for deoxyHbOH and an increase for oxyHb, which stabilized at a level of about 81 ± 5% and 19 ± 5%, respectively, only after 9 h. Quantitative analysis of the Δ(oxyHb) change estimated as the difference between the oxyHb level measured after 9 and 2 h at 85 K under low N2 pressure (to slow down oxyHb formation) was significantly higher in normotensives than in hypertensive patients with or without hypercholesterolemia, 19.9 versus -4.2, p < 0.02. Our findings indicate an impaired oxygen release by Hb in RBCs of patients with hypertension under low oxygen pressure which if present in vivo may cause hypoxemia and

    The southern portion of the United States has the highest mortality due to cardiovascular disease of any region of the country. The prevalence of hypertension in the South is also higher. Dietary intake of sodium, an overweight condition, and genetic factors may contribute to the problem. The role of trace elements is also a factor in producing hypertension. The objective of the present study was to explore the relationship of selected trace elements with tensive status using hair as a biopsy material. The study examined the differences in hair elemental concentrations between adult black female hypertensives and normotensives from low socioeconomic backgrounds.

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.

    The relationship between calcium intake and hypertension is receiving increased research attention. The prevalence of hypertension is high among the obese populations. Calcium is a mineral that influences blood pressure. The aim of the study was to examine the association between calcium intake and hypertension in a large nationally representative sample of obese American adults. A total of 14,408 obese adults aged 20 years or older were obtained from the 1999-2010 National Health and Nutrition Examination Survey. Analysis of variance and linear regression models were used to examine relationships between calcium intake and systolic blood pressure (SBP) as well as diastolic blood pressure (DBP). Multiple logistic regression models were used to examine the association between calcium intake and hypertension after adjusting for potential confounders and interactions, including: age, race, education level, alcohol use, smoking, diabetes status, sodium intake and potassium intake. Calcium intake was significantly lower for the hypertensive group compared with the normotensive group (P<0.0001), especially among those obese female young adults aged 20-44 years and among non-diabetic obese adults. Based on ordinary linear regression analysis, a significant inverse relationship was detected, SBP and DBP decreased if calcium intake increased (SBP: regression coefficient estimate=-0.015, P<0.0001; DBP: regression coefficient estimate=-0.028, P<0.0001). Multiple logistic regression showed that calcium intake was negatively associated with the probability of hypertension (odds ratio (OR)=0.81, 95% confidence interval (CI): 0.74-0.87, P<0.0001). In stratified analysis, calcium intake in youngest adults (age 20-44 years) had the lowest likelihood of hypertension (OR=0.77, 95% CI: 0.64-0.93, P<0.0001), the inverse relationship between calcium intake and probability of hypertension was stronger among females (OR: 0.68, 95% CI: 0.55-0.84, P<0.0001), when compared with the whole

    Phaeochromocytomas may be discovered incidentally when patients present with hypertensive crisis during general anaesthesia. A 49-year-old man underwent thyroidectomy 25 years ago and was diagnosed to have spindle cell carcinoma of the thyroid. He presented with recent onset of hoarseness of voice and was found to have a vocal cord nodule. He developed a hypertensive crisis during surgery. He was subsequently evaluated and found to have bilateral phaeochromocytoma. Further evaluation revealed a RET proto-oncogene mutation at codon 634 consistent with multiple endocrine neoplasia (MEN)-2A.

    Although there is strong evidence that hypertension leads to cognitive decline, especially in the executive domain, the relationship between blood pressure and cognition has been conflicted. Hypertension is characterized by blood pressure elevation and increased arterial stiffness. We aimed at investigating whether arterial stiffness would be superior to blood pressure in predicting cognitive decline and explaining the hypertension-executive decline association. A randomly selected asymptomatic population (n=591, age=49.2 years, 70% women, 27% black, and education=18 years) underwent annual vascular and cognitive assessments. Cognition was assessed using computerized versions commonly used cognitive tests, and principal component analysis was used for deriving cognitive scores for executive function, memory, and working memory. Arterial stiffness was measured by carotid-femoral pulse wave velocity (PWV). Higher PWV, but not blood pressure, was associated with a steeper decline in executive (P=0.0002), memory (P=0.05), and working memory (P=0.02) scores after adjusting for demographics, education, and baseline cognitive performance. This remained true after adjusting for hypertension. Hypertension was associated with greater decline in executive score (P=0.0029) and those with combined hypertension and elevated PWV (>7 m/s) had the greatest decline in executive score (P value hypertension×PWV=0.02). PWV explained the association between hypertension and executive function (P value for hypertension=0.0029 versus 0.24 when adjusting for PWV). In healthy adults, increased arterial stiffness is superior to blood pressure in predicting cognitive decline in all domains and in explaining the hypertension-executive function association. Arterial stiffness, especially in hypertension, may be a target in the prevention of cognitive decline.

    High blood pressure is a major health problem, particularly among Black Americans, and many Black Americans are unaware that they have the disease. In 2003, new guidelines (JNC 7) were created for classifying blood pressure including a category designated as "pre-hypertension." We examined the prevalence of hypertension based on JNC 7 guidelines in Black Americans from the study of Everyday Life for Black American Adults: Stress, Emotional and Cardiovascular Responses. In this study, 211 (N = 211) participants had no history of hypertension and were not taking anti-hypertensive medications. Demographic factors were also explored in relationship to the JNC 7 classifications. Using JNC 7, only 28.9% of the participants had normal blood pressures. Of those with abnormal blood pressures, 37.8% were pre-hypertensive. Surprisingly, there was a high prevalence of hypertension, which might be explained by a lack of awareness of their disease status, lack of desire to acknowledge it, or fear of having a disease. The pre-hypertension category allows for earlier identification of those at risk for developing hypertension so that early interventions can deter its debilitating effects. PMID:16570640

    Essential hypertension is characterized by a left ventricular dysfunction. However, the majority of the studies performed so far investigated patients under drug treatment and/or with concomitant diseases, such as obesity, diabetes, metabolic syndrome or coronary heart disease, which per se may affect diastolic function independently on the blood pressure elevation. The present study aimed at investigating left ventricular diastolic function in untreated, uncomplicated and newly diagnosed hypertensive patients by employing both routine echo-Doppler and pulse tissue-Doppler technique. Data were collected in 86 middle-aged essential hypertensive patients and in 18 sex-matched normotensive controls. At the echo-Doppler approach, about half of the hypertensive patients displayed a diastolic dysfunction (n = 44, E/A: 0.79 ± 0.02). They showed body mass index values slightly greater than hypertensive patients without diastolic dysfunction but superimposable blood pressure values and metabolic variables. When assessed via the pulse tissue-Doppler approach, patients with a reduced E/A displayed an Em/Am ratio significantly lower than patients without diastolic dysfunction and control subjects. This was the case when the data were related to the lateral and septal mitral annulus or averaged together. Furthermore, whereas myocardial systolic peak velocity (Sm) was lower in hypertensive patients than in control subjects, no significant between-groups difference in E/Em ratio was observed. Differently from the data obtained via the echo-Doppler approach, the tissue-Doppler method in patients without diastolic dysfunction showed a significant higher deceleration and isovolumetric relaxation times, with a lower Em velocity compared with the normotensive subjects. At the stepwise multiple regression analysis E/A ratio and E'/A' values were related with left ventricular mass index and body mass index after correction for age. These data provide evidence that diastolic

    This study evaluated the levels of knowledge of hypertension and the associated medications among hypertension patients in Lesotho and assessed the significance of these indicators on hypertension treatment outcomes. About 81% (n = 212) of the patients had hypertension monocondition while the remaining had multiple chronic conditions. Seventy-six percent of the patients had uncontrolled hypertension. Nearly 36% had inadequate knowledge about hypertension while 44% had inadequate knowledge about their medicines. In total, 52.4% of the patients defaulted appointment dates while 64.6% failed to take their medications as prescribed at least once. Inadequate knowledge of antihypertensive medicines was significantly associated (P = .028) with having uncontrolled hypertension. Inadequate knowledge of antihypertensive medicines is an important determinant of uncontrolled hypertension. Improving the knowledge of hypertension and the associated medications is an important intervention required in this population. PMID:26775548

    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.

    Compliance with antihypertensive therapy was examined by a questionnaire in 124 essential hypertension patients in an outpatient hypertension clinic. It was found that antihypertensive drugs were used regularly by only 62% of patients, with forgetting and feeling of well-being without therapy the principal reasons given for irregular drug taking. Treatment of hypertension is reported to have a deleterious effect on physical and mental activity, routine activities, sexual activity, memory, athletics and family life in only 2% of patients. Patients who were aware that increased BP reduces life span used the prescribed drugs more regularly and came regularly for checkups compared with patients lacking the relevant information. Patients over 60 years of age and smokers exhibited the worst compliance. No significant differences were found for sex or duration of treatment. With regard to nonpharmacological measures, most patients were willing to begin a programme of regular physical exercise, reduce weight, learn relaxation techniques and reduce alcohol intake: smokers, however were unable to stop the habit.

    Background. Pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) are fatal, noncurable, but treatable diseases that strongly affect the patients. Objective. To describe patients' experience of information relating to PAH or CTEPH. Methods. A qualitative method using content analysis was applied. Seventeen patients (thirteen women and four men) aged 28-73 years from a regional PAH centre were individually interviewed. Results. Three categories that describe patients' experiences of information emerged: handling of information, struggling with feelings that also affect others, and vulnerability associated with uncertainty. The patients would have welcomed more information to relatives from the healthcare professionals. Shortcomings on communicating a prognosis were experienced. The mediated information and knowledge gave the patients insight into physical or psychosocial problems. Mutual exchange of information between patients and healthcare professionals were marred by different experiences of attitudes, behaviour, and ownership. Conclusions. In the future, healthcare organizations must struggle to achieve a holistic healthcare by making it more person-centred, and they must also promote cooperation between PAH centres and local healthcare providers. It is essential to determine the most appropriate and valuable path of information and communication and, thereby, the most cost-effective management of PAH or CTEPH. PMID:25197567

    AIM: To assess the prevalence of portal hypertension (PH) related colorectal lesions in liver transplant candidates, and to evaluate its association with the severity of PH. METHODS: Between October 2004 and December 2005, colonoscopy was performed in 92 cirrhotic liver transplant candidates. We described the lesions resulting from colorectal PH and their association with the grade of PH in 77 patients who underwent measurement of hepatic venous pressure gradient (HVPG). RESULTS: Mean age was 55 years and 80.7% of patients were men. The main etiology of cirrhosis was alcoholism (45.5%). Portal hypertensive colopathy (PHC) was found in 23.9%, colonic varices in 7.6% and polyps in 38% of patients (adenomatous type 65.2%). One asymptomatic patient had a well-differentiated adenocarcinoma. The manifestations of colorectal PH were not associated with the etiology of liver disease or with the Child-Pugh grade. Ninety percent of patients with colopathy presented with gastroesophageal varices (GEV), and 27.5% of patients with GEV presented with colopathy (P = 0.12). A relationship between higher values of HVPG and presence of colopathy was observed (19.9 ± 6.2 mmHg vs 16.8 ± 5.4 mmHg, P = 0.045), but not with the grade of colopathy (P = 0.13). Preneoplastic polyps and neoplasm (P = 0.02) and spontaneous bacterial peritonitis (P = 0.006) were more prevalent in patients with colopathy. We did not observe any association between previous β-blocker therapy and the presence of colorectal portal hypertensive vasculopathy. CONCLUSION: PHC is common in cirrhotic liver transplant candidates and is associated with higher portal pressure. PMID:19824111

    This report describes the diagnosis and treatment of pulmonary arterial hypertension (PAH) in an adult male captive chimpanzee. Although cardiovascular disease in general is common in human and great apes, diagnosis and treatment of PAH in nonhuman primates are uncommon. In the case we present, the adult chimpanzee was diagnosed with an arrhythmia during an annual physical examination and later with PAH during a scheduled cardiovascular evaluation. PAH can either be primary or secondary and can lead to right ventricular overload and heart failure. This description is the first case study of pulmonary arterial hypertension in a great ape species. PMID:18947173

    Out of 100 patients with osteoarthritis (OA), almost 40 have a concomitant diagnosis of hypertension. Nonsteroidal anti-inflammatory drugs (NSAIDs) and cyclooxygenase-2 (COX-2) inhibitors may trigger a rise in blood pressure (BP), which is more marked in patients with established hypertension. NSAIDs and COX-2 inhibitors attenuate the antihypertensive effect of several antihypertensive agents. Frequent BP controls are needed in treated hypertensive patients who are concomitantly receiving NSAIDs or COX-2 inhibitors because even a small increase in BP may be associated with an important rise in the risk of major cardiovascular complications. In meta-analyses, an increase in systolic BP of 5mmHg was associated with a 25% higher risk of cardiovascular events. These data have been confirmed in randomized studies with rofecoxib and celecoxib, where a modest increase in BP was associated with a significantly higher risk of cardiovascular disease. There is emerging evidence that the COX-inhibiting nitric oxide donator (CINOD) class is promising in the treatment of patients with OA. Naproxcinod, the first CINOD investigated in clinical trials, is composed of the traditional NSAID naproxen covalently bound to the nitric oxide (NO)-donating moiety butanediol mono-nitrate (BDMN). The molecule has the potential to provide a sustained release of NO. In clinical studies, naproxcinod prevented the BP rise in normotensive and hypertensive patients observed with naproxen. The BP benefit of naproxcinod over naproxen was greater in patients concomitantly receiving angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers. These investigational data suggest that naproxcinod is a valuable alternative to NSAIDs and COX-2 inhibitors for treatment of OA patients. PMID:22870450

    Background: Cardiovascular disease risk factors have a tendency to cluster. The presence of such a cluster in an individual has been designated the metabolic syndrome (MetS). There is a paucity of reports of the prevalence of MetS in hypertensive patients in south east Nigeria. This study was undertaken to determine the prevalence of the metabolic syndrome (MetS) among newly diagnosed hypertensive patients using the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) criteria in a tertiary healthcare centre in South East Nigeria. Materials and Methods: A population of 250 consecutive newly diagnosed adult hypertensive patients (126 males and 124 females) was evaluated. Blood pressure and anthropometric measurements were done using standardized techniques. After an overnight fast, blood samples were taken for glucose and lipid profile assays. The NCEP ATP III criteria were then applied for the diagnosis of MetS. Results: The prevalence of the MetS among the study population was 31.2%. The sex-specific prevalences were 15.1% and 47.6% among male and female patients respectively. A large number of the patients (40.4%) were at a high potential risk of developing the MetS as they already met 2 of the criteria. The MetS prevalence increased progressively from 14.3% through 23.8%, in the patients aged 24-33years and 34-43 years, respectively to a peak (40.4%) among those aged 44-53 years before declining in those aged 54-63 years (31.8%), 64-73 years (33.3%) and 74 years and above (20.6%). Central obesity was the most common component of the MetS being present in 50.4% of patients (28.6% of males and 72.6% of females). Of the other components, low HDL-C was present in 38.8% (26.2% of males and 51.6% of females), elevated FBS in 12.8% (6.3% of males and 19.4% of females) and elevated triglycerides in 8.8% (11.9% of males and 5.6% of females). Conclusion: The prevalence of the MetS is high among newly diagnosed hypertensive patients in Nnewi

    Patients with hypertensive crises, especially hypertensive emergencies, require immediate admittance to an intensive care unit for rapid blood pressure (BP) control. The authors analyzed the prevalence of hypertensive crisis, the clinical characteristics, and the evolution of patients with hypertensive emergencies and urgencies. Patients were divided into 3 groups according to their BP values: group I, predominant systolic hypertension (≥180/≤119 mm Hg); group II, severe systolic and diastolic hypertension (≥180/≥120 mm Hg); and group III, predominant diastolic hypertension (≤179/≥120 mm Hg). Of all of the patients admitted to a coronary care unit, 538 experienced a hypertensive crisis, which represented 5.08% of all admissions. Hypertensive emergency was predominant in 76.6% of the cases, which corresponded to acute coronary syndrome and acute decompensated heart failure in 59.5% and 25.2% of the cases, respectively. A pattern of predominant systolic hypertension (≥180/≤119 mm Hg) was most commonly observed in the hypertensive crisis group (71.4%) and the hypertensive emergency group (72.1%). The medications that were most commonly used at onset included intravenous vasodilators (nitroglycerin in 63.4% and sodium nitroprusside in 16.4% of the patients). The overall mortality rate was 3.7%. The mortality rate was 4.6% for hypertensive emergency cases and 0.8% for hypertensive urgencies cases.

    Less than 25 percent of patients with hypertension in the United States have their blood pressure under control, mainly because of inadequate or inappropriate therapy and noncompliance. Approximately one half of these treatment failures are related to factors such as cost and adverse effects of medication, complex drug regimens, failure of clinicians to fully realize the benefits of antihypertensive therapy and lack of patient education. Other major causes of unresponsiveness to antihypertensive therapy include "white coat" hypertension, pseudohypertension, obesity, volume overload, excess alcohol intake and sleep apnea, as well as inappropriate antihypertensive drugs and drug combinations, and unfavorable interactions with prescription and other drugs. In many patients, these factors must be dealt with before blood pressure can be controlled. PMID:9518949

    High blood pressure (BP) >140/90 mm Hg is seen in 75% of patients with acute ischemic stroke and in 80% of patients with acute intracerebral hemorrhages and is independently associated with poor functional outcome. While BP reduction in patients with chronic hypertension remains one of the most important factors in primary and secondary stroke prevention, the proper management strategy for acute hypertensive response within the first 72 hours of acute ischemic stroke has been a matter of debate. Recent guidelines recommend clinical trials to ascertain whether antihypertensive therapy in the acute phase of stroke is beneficial. This review summarizes the current data on acute hypertensive response or elevated BP management during the first 72 hours after an acute ischemic stroke. Based on the potential deleterious effect of lowering BP observed in some clinical trials in patients with acute ischemic stroke and because of the lack of convincing evidence to support acute BP lowering in those situations, aggressive BP reduction in patients presenting with acute ischemic stroke is currently not recommended. While the early use of angiotensin receptor antagonists may help reduce cardiovascular events, this benefit is not necessarily related to BP reduction. PMID:27366297

    In an open-label study, we compared the efficacy and safety of intravenous infusion of fenoldopam mesylate with that of sodium nitroprusside in patients with severe hypertension or in hypertensive crisis. Both antihypertensive medications were infused at a maximal dose increment of 0.2 microgram/kg/min (fenoldopam) and 1 microgram/kg/min (nitroprusside), with a maximal infusion rate of 1.5 micrograms/kg/min fenoldopam mesylate or 8 micrograms/kg/min sodium nitroprusside. Once the desired reduction in diastolic blood pressure was achieved (less than 110 mm Hg if initial diastolic blood pressure was 120-149 mm Hg, or by at least 40 mm Hg if initial diastolic blood pressure was 150-190 mm Hg), the maximal infusion rate used was maintained for at least 1 hour, and then, the infusion was slowed gradually over 2 hours. After the infusion treatment, patients remained in the hospital for 2 days of follow-up. Both antihypertensive agents successfully controlled the blood pressure in all the patients by the end of the maintenance periods. Between the baseline and the end of the maintenance period, analysis of variance showed that the changes in the variables induced by fenoldopam mesylate did not differ significantly from those induced by sodium nitroprusside. The incidence of side effects listed were similar in both groups of patients. The detection of toxic levels of thiocyanate in two patients treated with nitroprusside, however, shows that fenoldopam might be preferable for the control of a hypertensive crisis or severe hypertension in patients with decreased renal function.

    We compared the obesity parameters and selected adipokines-leptin, adiponectin, and resistin-in obese patients with hypertension and normotensive patients. A total of 67 nondiabetic obese outpatients were divided into 2 groups: A-hypertensive and B-normotensive. Serum levels of leptin, adiponectin, resistin, and insulin were measured. Weight, height, waist circumference, and hip circumference were measured to calculate waist-to-hip ratio (WHR), weight-to-height ratio, visceral adiposity index, and body adiposity index (BAI). Among patients with hypertension, significant positive correlations were observed between leptin and body mass index and BAI (r = .31 and r = .63, respectively). In normotensive patients, leptin positively correlated with BAI (r = .73, P < .01) and negatively with WHR (r = -.55, P < .0001); adiponectin negatively correlated with WHR (r = .38, P < .01) and BAI (r = .52; P < .0001), and resistin negatively correlated with WHR (r = -.36, P < .05). In conclusion, visceral obesity and leptin are associated with hypertension in obese patients.

    Hypertension is a major risk factor of cardiovascular disease in China, and yet little is known about health-related quality of life (HRQOL) and its associations with demographic and social-economic characteristics in middle-aged patients with hypertension. A cross-sectional survey was undertaken in Chongqing, China, using a multistage stratified random sampling methodology. Data was collected on 1,224 eligible adults, aged between 45 and 53 years, including the Medical Outcomes Survey Short Form-36 to measure HRQOL. Hypertension was associated with poor state of physical functioning, role-physical, bodily pain, general health, vitality, and social function (p < 0.05 for all). In multivariable analyses, education level, job conditions, average monthly income, smoking status, sleep quality, perception of relationship with family, childhood breastfeeding history, and body mass index were associated with domains of SF36 among those with hypertension (p < 0.05 for all). Hypertensive respondents with high education, marital status, breastfeeding, higher incomes, good quality of sleep, positive relationship with family, and higher body mass index have better HRQOL in middle-aged people with hypertension. Those unemployed had a better state of general health and had a poorer state of social function. Nonsmokers had a poorer state of bodily pain than smokers. This study provides detailed information of the implications for health care providers to gain a more complete picture of their hypertension patients' health.

Hypertension was associated with poor state of physical functioning, role-physical, bodily pain, general health, vitality, and social function (p < 0.05 for all). In multivariable analyses, education level, job conditions, average monthly income, smoking status, sleep quality, perception of relationship with family, childhood breastfeeding history, and body mass index were associated with domains of SF36 among those with hypertension (p < 0.05 for all). Hypertensive respondents with high education, marital status, breastfeeding, higher incomes, good quality of sleep, positive relationship with family, and higher body mass index have better HRQOL in middle-aged people with hypertension. Those unemployed had a better state of general health and had a poorer state of social function. Nonsmokers had a poorer state of bodily pain than smokers. This study provides detailed information of the implications for health care providers to gain a more complete picture of their hypertension patients' health. PMID:27630771

    Background. Hypertensive haemodialysis patients may be at a high risk for cardiovascular events. This study was undertaken to ascertain whether the calcium channel blocker amlodipine reduces mortality and cardiovascular events in these high-risk patients. Methods. We evaluated the effects of amlodipine on cardiovascular events in 251 hypertensive haemodialysis patients in an investigator-designed, prospective, randomized, double-blind, placebo-controlled, multicenter trial. One hundred and twenty-three patients were randomly assigned to amlodipine (10 mg once daily) and 128 to placebo. The primary endpoint was mortality from any cause. The secondary endpoint was a composite variable consisting of mortality from any cause or cardiovascular event. Analysis was by intention-to-treat. The trial was registered with ClinicalTrials.gov (number NCT00124969). Results. The median age of patients was 61 years (25% percentile − 75% percentile, 47–69), and the median follow-up was 19 months (8–30). Fifteen (12%) of the 123 patients assigned to amlodipine and 22 (17%) of the 128 patients assigned to placebo had a primary endpoint [hazard ratio 0.65 (95% CI 0.34–1.23); P = 0.19]. Nineteen (15%) of the 123 haemodialysis patients assigned to amlodipine and 32 (25%) of the 128 haemodialysis patients assigned to placebo reached the secondary composite endpoint [hazard ratio 0.53 (95% CI 0.31–0.93); P = 0.03]. Conclusion. Amlodipine safely reduces systolic blood pressure and it may have a beneficial effect on cardiovascular outcomes in hypertensive haemodialysis patients. PMID:18511605

    Hypertensive emergencies and hypertensive urgencies in children are uncommonly encountered in the pediatric emergency department and intensive care units, but the diseases are potentially a life-threatening medical emergency. In comparison with adults, hypertension in children is mostly asymptomatic and most have no history of hypertension. Additionally, measuring accurate blood pressure values in younger children is not easy. This article reviews current concepts in pediatric patients with severe hypertension.

    Background/Objective Hypertension is an important risk factor for cardiovascular disease, and diet has been identified as a modifiable factor for preventing and controlling hypertension. Besides, epidemiological studies have suggested an inverse association between polyphenol intake and cardiovascular diseases. The aim of this study was to evaluate the association between the intake of polyphenols and hypertension in a general population of Sao Paulo. Methods Data came from the ‘Health Survey of Sao Paulo (ISA-Capital)’ among 550 adults and older adults in Sao Paulo, Brazil. Diet was assessed by two 24-hour dietary recalls (24HR). Usual intakes were calculated using the Multiple Source Method. Polyphenol intake was calculated by matching food consumption data from the 24HR with the Phenol-Explorer database. The associations between the hypertension and tertiles of the total and classes of polyphenols intake were tested by multivariate logistic regression analysis. Results After multivariate adjustment for potential confounding factors the findings showed an inverse and linearly association between the hypertension and highest tertiles of tyrosols (OR = 0.33; 95%CI 0.18, 0.64), alkylphenols (OR = 0.45; 95%CI 0.23, 0.87), lignans (OR = 0.49; 95%CI 0.25, 0.98), as well as stilbenes (OR = 0.60; 95%CI 0.36, 0.98), and other polyphenols (OR = 0.33; 95%CI 0.14, 0.74). However, total polyphenol intake, and phenolic acids were significantly associated only in the middle tertile with hypertension and flavonoids were not significant associated. Conclusion There is an inverse and linearly association between the highest tertile of some classes of polyphenols, such as, tyrosols, alkylphenols, lignans, stilbenes, other polyphenols and hypertension.

    A hypertensive response to exercise (HRE) is known to be associated with higher risk of heart failure and future cardiovascular events in patients with hypertension. Left atrial volume index (LAVI) is associated with the diastolic dysfunction, indicating exercise intolerance. Therefore, we investigated whether LAVI is relevant to HRE during cardiopulmonary exercise test (CPET). We studied 118 consecutive hypertensive patients (61 men, 57±11 years) and 45 normotensive control subjects (16 men, 54±8 years). Clinical characteristics, CPET, echocardiographic and laboratory findings were assessed at the time of enrollment. HRE was defined as maximum systolic blood pressure (SBP)⩾210 mm Hg in men and ⩾190 mm Hg in women. HRE was more prevalent in hypertensive patients compared with normotensive control subjects (50.8% vs. 20.0%, P<0.001). Age and baseline SBP were shown to be associated with HRE in normotensive control subjects, as were baseline SBP and LAVI in hypertensive group. In multivariate analysis, LAVI was found to be an independent predictor of HRE in hypertensive patients (P=0.020) but not in normotensive control subjects (P=0.936) when controlled for age, sex, body mass index and peak oxygen consumption. Higher LAVI, reflecting the duration and severity of increased left atrial pressure is independently associated with HRE in hypertensive patients, but not in normotensive control subjects.

    Background The purpose of the study was to examine pulmonary hypertension (PH) patients’ quality of life (QOL) for the first time in Finland. Methods This was a non-interventional, cross-sectional study. The SF-36v2 questionnaire was sent to the PH patients who had been referred to or followed up on at the Helsinki University Central Hospital's pulmonary clinic for idiopathic pulmonary arterial hypertension, associated pulmonary arterial hypertension (APAH), or chronic thromboembolic PH (CTEPH). The patients were on pulmonary arterial hypertension (PAH) – specific drugs, were at least 18 years old, and had signed an informed consent. Results There were 62 patients who fulfilled the inclusion criteria, and 53% of respondents rated their health as moderate. Similarly, 55% of respondents rated their health status approximately the same compared to their situation 1 year ago. QOL was impaired in all other subscales, except for the mental health and mental component score. A majority of patients suffered from PH symptoms, which worsened their QOL. The greatest impact on their QOL was associated with a high World Health Organization (WHO) functional class (FC), poor performance in a 6-min walking test (6MWT), symptoms, oxygen therapy, elevated pro-brain natriuretic peptide, pericardial effusion, APAH etiology, and being retired from work. Conclusions The respondents had a reduced QOL, compared to the general population, in all other subscales, except for mental health. APAH patients had the worst QOL. Good results in functional capacity measures (WHO FC, 6MWT) were associated with a better QOL. Patients’ QOL can be improved by reducing the symptoms of PAH. PMID:26787306

    In the present study the relative quantity subpopulations of lymphocytes, activated T- lymphocytes and CD95-antigen (Fas/APO-1) expression on lymphocytes in the peripheral blood of patients with arterial hypertension and obesity in comparison with the healthy persons was determined. The cells were analyzed by the method of flow cytometry using Beckman Coulter FC 500 cytometer. The following of cells subsets: CD19+, CD3+, CD3+CD4+, CD3+CD8+, CD3-CD16+CD56+, CD3+CD16+CD56+, CD3+CD25+, CD3+HLA-DR+, CD45+CD95+ were investigated. In this research was establish the rise of immunoregulatory index (CD3+CD4+/CD3+CD8+) in consequence of increase the percentages of T-helper and decrease the cytotoxic T-lymphocytes in patients with arterial hypertension and obesity in comparison with the healthy persons. In the peripheral blood of patients with arterial hypertension and obesity were observed a greater level of activated T-lymphocytes (CD3+CD25+, CD3+HLA-DR+), that reflect the increase activity of T-cell immunity. In these patients a greater level of NKT-cells (CD3+CD16+CD56+) and lymphocytes expression of CD95-antigen in comparison with the healthy persons also was noted. The direct correlation between the increased quantity of T-helper lymphocytes, activated T-lymphocytes, NKT-cells, lymphocytes expression of CD95-antigen, and index of body mass in patients with arterial hypertension and obesity was found.

    Endoscopic ultrasound (EUS) has revolutionized the diagnostic and therapeutic approach to patients with gastrointestinal disorders. Its application in patients with liver disease and portal hypertension is increasing. Patients with chronic liver disease are at risk for development of portal hypertension sequale such as ascites, spontaneous bacterial peritonitis and gastroesophageal varices. Bleeding esophageal and gastric varices are among the most common causes of mortality in patients with cirrhosis. Thus, early detection and treatment improve the outcome in this population. EUS can improve the detection and diagnosis of gastroesophageal varices and collateral veins and can provide endoscopic therapy of gastroesophageal varices such as EUS-guided sclerotherapy of esophageal collateral vessels and EUS-guided cynoacrylate (Glue) injection of gastric varices. EUS can also provide knowledge on the efficacy of pharmacotherapy of portal hypertension. Furthermore, EUS can provide assessment and prediction of variceal recurrence after endoscopic therapy and assessment of portal hemodynamics such as E-Flow and Doppler study of the azygous and portal veins. Moreover, EUS-guided fine needle aspiration may provide cytologic diagnosis of focal hepatic tumors and analysis of free abdominal fluid. Using specialized EUS-guided needle biopsy, a sample of liver tissue can be obtained to diagnose and evaluate for chronic liver disease. EUS-guided fine needle injection can be used to study portal vein pressure and hemodynamics, and potentially could be used to assist in exact measurement of portal vein pressure and placement of intrahepatic portosystemic shunt.

    The efficacy of isradipine, a new antihypertensive dihydropyridine calcium antagonist, was prospectively studied in Ethiopian patients with uncontrolled severe hypertension on multiple antihypertensive agents. Enrolled were 13 patients based on inclusion and exclusion criteria and 12 patients completed the study. The study design included a three-week wash-out period followed by eight weeks of active treatment. Eleven patients (92%) took diuretics in addition to isradipine. Patients were started on 2.5mg of isradipine twice daily and the dose was increased to 5mg twice daily in eight (67%) patients since the diastolic blood pressure (DBP) remained above 90mmHg four weeks after the initiation of therapy. The treatment resulted in a mean decrease of 42mmHg in systolic blood pressure (SBP) (p < 0.0001) and 34mmHg in DBP (p < 0.0001). Seven patients (58%) achieved normalization of DBP and in the remaining 5 (42%) the DBP became less than 105mmHg. Almost all patients experienced mild and transient side effects resulting from vasodilation but all tolerated these except one who dropped out from the study. In conclusion, these results indicate that isradipine combined with a diuretic is a safe and effective antihypertensive agent in Ethiopian patients with uncontrolled hypertension. PMID:7601086

    This Hypertension Grand Rounds discusses pharmacological treatment of hypertension in individuals who have survived 9 decades on earth. This rapidly growing group of relatively active and healthy elderly people is at high risk for hypertension, its treatment, and its adverse consequences, including stroke and heart failure. In this age group, the most common abnormality is elevated systolic blood pressure, which is much more predictive of stroke and heart disease death after 53 years of age. With the possible exception of the Antihypertensive and Lipid Lowering to prevent Heart Attack Trial (ALLHAT), recent clinical trials have emphasized the overriding importance of lowering blood pressure rather than the specific agent chosen to begin therapy. In 1999, a metaanalysis of 7 clinical trials that enrolled 1670 subjects >80 years of age indicated that active antihypertensive drug therapy significantly reduced stroke by 34% and heart failure by 39% but was associated with a nonsignificant 6% increase in mortality. The HYpertension in the Very Elderly Trial (HYVET) will enroll 2100 patients >80 years of age and will compare 2 groups randomized to indapamide+/-perindopril versus placebo+/-placebo for incident stroke during 5 years of follow-up. This study should answer lingering questions about whether active antihypertensive therapy is associated with a major and significant reduction in cardiovascular morbidity and mortality in this age group as it clearly does in younger hypertensives. Its choice of a diuretic as initial therapy is consistent with other trials, but chlorthalidone is the drug with the most compelling evidence in large US trials that included very elderly patients.

    The diagnosis of arterial hypertension cannot be in doubt with repeated high blood pressure readings (140/90 under 40 years and over 40 years 160/95). In particular it will be easier to reconcile a patient who has no symptoms and who is not motivited by complaints to the understanding of a usually lifelong therapy by an exhaustive discussion. The patient must know that the risk of secondary cardiac diseases increases continuously with the level of the average arterial pressure (both systolic and diastolic) and that this average pressure includes all values of the excessive range of fluctuation of the blood pressure in hypertensive disease (stress peaks, resting values). The diagnostic program leads to a causal (surgical) therapy only in isolated cases (1 to 2%). For symptomatic therapy the general measures "adjustment of the way of living" and "diet" are the decisive basis for effective treatment.

    Recent advances in automatic speech recognition and related technologies allow computers to carry on conversations by telephone. 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.

    The Nutrition Facts (NF) label was established to help individuals monitor their nutrient intake and select healthier foods. This tool is particularly useful for individuals for whom dietary improvements are recommended, such as those with hypertension. Study objectives were to examine the independent association between hypertension and frequency of use of the NF label for sodium information and determine whether frequent use in individuals with hypertension was associated with differences in mean sodium intake assessed through 24-hour urine samples. Data came from the New York City Community Health Survey Heart Follow-Up Study, a cross-sectional study conducted in 2010 in a representative sample of New York City adults (n=1,656). Participants were asked questions regarding frequency of checking the NF label and also had 24-hour urine samples collected to assess actual sodium intake. Results indicated that hypertension was associated with frequent use of the NF label for sodium information (adjusted odds ratio 1.71, 95% CI 1.07 to 2.73). In individuals with hypertension, sodium intake did not differ between frequent vs nonfrequent use of the NF label for sodium information (3,084 mg/day vs 3,059 mg/day; P=0.92). Although individuals with hypertension compared to those with no hypertension had 71% higher odds of frequently using the NF label for sodium information, suggesting they may be interested in decreasing sodium intake, sodium intake did not differ by frequency of NF label use among those with hypertension. Future research should explore strategies to ensure that when nutrition information is used, it is translated into meaningful results, especially in individuals with health concerns such as hypertension.

    Vascular abnormalities may exist before clinical hypertension. Using Poisson regression, the authors studied the association of coronary artery calcium (CAC), common carotid intima-media thickness (CIMT), aortic distensibility, and large and small arterial elasticity with incident hypertension among 2,512 normotensive US adults free of cardiovascular disease. Incidence rate ratios for incident hypertension (blood pressure ≥140/90 mm Hg or new antihypertensive medication) were calculated. Increased CAC was associated with incident hypertension in demographics-adjusted models (incidence rate ratio (IRR) = 1.35, 95% confidence interval (CI): 1.04, 1.75; IRR = 1.35, 95% CI: 1.02, 1.78; and IRR = 1.59, 95% CI: 1.12, 2.25 for CAC scores of 30–99, 100–399, and ≥400, respectively) but was attenuated after further adjustment. Increased common CIMT was associated with incident hypertension (IRR = 1.77, 95% CI: 1.28, 2.46 for quintile 4; IRR = 1.80, 95% CI: 1.28, 2.53 for quintile 5). Participants with the lowest, compared with the highest, aortic distensibility had an increased risk of hypertension (IRR = 1.75, 95% CI: 1.10, 2.79), as did those with the lowest large arterial elasticity (IRR = 1.49, 95% CI: 1.11, 1.99). Lower small arterial elasticity was incrementally associated with incident hypertension starting at quintile 2 (IRR = 2.01, 95% CI: 1.39, 2.91; IRR = 2.47, 95% CI: 1.71, 3.57; IRR = 2.73, 95% CI: 1.88, 3.95; and IRR = 2.85, 95% CI: 1.95, 4.16). Structural and functional vascular abnormalities are independent predictors of incident hypertension. These findings are important for understanding the pathogenesis of hypertension. PMID:19951938

    Inadequate blood pressure (BP) control may be linked with poor adherence to guidelines by the treating physician. This study aimed at assessing the rates of controlled hypertension as per the 2009 Reappraisal of the 2007 European Society of Cardiology/European Society of Hypertension (ESC/ESH) guidelines in 2185 hypertensive adults across five countries (Algeria, Pakistan, Ukraine, Egypt and Venezuela). The rates of controlled hypertension according to physician perception, type of therapy and risk factors were evaluated. Overall, 40% of patients had controlled hypertension according to the guidelines. A marked divergence in the rates of controlled hypertension as assessed by physicians and guidelines was observed (72% vs 40%). The presence of high/very high risks was linked to poor BP control. High salt intake [29%; odds ratio (OR) 9.94, 95% confidence interval (CI) 6.72;14.69], treatment non-adherence (27%; OR 7.32, 95% CI 4.82;11.13), lack of understanding of the treatment's importance (25%; OR 4.95, 95% CI 3.16;7.75), comorbidity (13%) and depression (9%; OR 10.50, 95% CI 5.37;20.54) were major reasons for not achieving hypertension control. Addition of another drug was the most frequent medication change prescribed. Poor rates of BP control warrant repeated promotion of guidelines while identifying potential contributing factors and implementing strategies that re-establish BP control. PMID:26873621

    Background Poor adherence is estimated to cause 125 thousand deaths per year and is linked to 10% of all hospital stays in the U.S. Up to one third of elderly hypertensive patients don't have adherence, which is responsible for high proportion of hospitalizations. Hypertension is also related to poor performance in tests that assess cognitive functions. On the other hand, poor cognitive performance is associated with low adherence to treatment. Objective To assess the association between cognitive function, anxiety and psychiatric disorders with adherence to drug treatment in patients with hypertension. Methodology and Principal Findings This a cohort studies with 56 adult patients with uncontrolled hypertension who participated of all meetings of a pharmaceutical intervention in a randomized clinical trial of pharmaceutical care. Cognitive function was measured by the Mini Mental State Examination (Mini-mental). The memory was measured by digit and word spans, tower and church shadow test, short story test and metamemory. Anxiety and psychiatric disorders were evaluated by the State Trace Anxiety Inventory and the Self-Report Questionnaire, respectively. The participants were classified as adherent or non-adherent to the drug treatment, according to the identification of plasma levels of hydrochlorothiazide. All non-adherent patients (n = 12) and 35 out 44 (79.5%) patients with adherence to treatment had at least one memory test with an altered score (P = 0.180). Participants with an unsatisfactory score in the Mini-mental had six-fold higher risk of non-adherence to treatment when compared to those with a normal score (RR = 5.8; CI 95%: 1.6–20.8; P = 0.007). The scores of anxiety and psychiatric disorders were not associated with adherence to the pharmacological treatment. Conclusion Cognitive deficit impairs adherence to drug therapy and should be screened as part of a program of pharmaceutical care to improve adherence to treatment. PMID

    Background In Peru, cardiovascular disease was the second most common cause of death in those aged 65 years or more in 2000. Hypertension is a major modifiable risk factor for cardiovascular disease, and if treated can significantly reduce cardiovascular disease risk. The objectives of this study were to investigate the prevalence of hypertension and levels of awareness, treatment and control in a deprived urban area of Peru. Methods A cross-sectional study was completed. Blood pressure measurements were recorded in triplicate. Hypertension was defined as systolic blood pressure ≥ 140 mmHg or diastolic blood pressure ≥ 90 mmHg, or self report of receiving antihypertensive medication at the time of interview. Results The study sample was 584 adults (29.1% male, mean age 35.3 years). Age standardized prevalence of hypertension was 19.5% (95% CI 9.9%, 29.1%) in men, 11.4% (95% CI 3.7%, 19.1%) in women, and 13.2% (95% CI 5.0%, 21.5%) overall. Among those with hypertension 38.3% (95% CI 22.7%, 53.9%, n = 18/47) were aware of their condition with greater awareness among women than men. Of those aware, 61.1% (n = 11/18) were treated, equating to 23.4% (95% CI 10.1%, 36.7%, n = 11/47) of all adults with hypertension. Of those treated 63.6% (n = 7/11) had controlled hypertension, equating to 14.9% (95% CI 3.0%, 26.8%, n = 7/47) of all adults with hypertension. Conclusion Levels of awareness and control in this population were low. Lack of control is likely to be due to both a failure to diagnose hypertension, especially among men, and initiate or comply with treatment, especially among women. These results suggest a considerable burden of undiagnosed hypertension, and poor levels of control in those treated, in a deprived urban area of Lima, Peru. PMID:18710540

    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.

  12. How should we manage a patient with masked hypertension?

    A number of studies have shown that masked hypertension (MH) confers an increased risk of target organ damage and of cardiovascular events suggesting that patients with MH would benefit from antihypertensive treatment. However, there is no general agreement about how this condition should be diagnosed. Although ambulatory blood pressure monitoring (ABPM) and self blood pressure measurement (SBPM) provide different and complementary clinical information, the recently published ESH/ESC guidelines for the management of arterial hypertension suggest that for initial assessment of the patient, SBPM may be more suitable in primary care and ABPM in specialist care. If SBPM provides borderline values it is advisable to confirm the diagnosis of MH with ABPM. As the prevalence of MH declines with repeated ABPMs the diagnosis of MH should be based on at least two ABPMs. Patients with MH should undergo a careful diagnostic work-up to assess the existence of additional risk factors including a worsened metabolic profile and the presence of target organ involvement. Treatment of the patient with MH should initially be addressed to improve the patient's lifestyle in order to decrease out-of-office blood pressure and to ameliorate metabolic data. If non-pharmacological measures are insufficient to normalize blood pressure, MH may benefit from pharmacological treatment but no clinical trial has been implemented as yet with the specific purpose of testing this hypothesis. Despite this lack of evidence, the 2013 ESH/ESC guidelines have recommended that in patients with MH also drug treatment should be considered because in patients with MH the risk of adverse outcome is very close to that in sustained hypertension. When ambulatory blood pressure is measured, pharmacological treatment may be modulated according to whether blood pressure is elevated during daytime hours or during sleep. PMID:24500867

    Background The human hypothalamus contains the neuropeptide FF (NPFF) neurochemical network. Animal experiments demonstrated that NPFF is implicated in the central cardiovascular regulation. We therefore studied expression of this peptide in the hypothalamus of individuals who suffered from essential hypertension (n = 8) and died suddenly due to acute myocardial infarction (AMI), and compared to that of healthy individuals (controls) (n = 6) who died abruptly due to mechanical trauma of the chest. Methods The frozen right part of the hypothalamus was cut coronally into serial sections of 20 μm thickness, and each tenth section was stained immunohistochemically using antibody against NPFF. The central section through each hypothalamic nucleus was characterized by the highest intensity of NPFF immunostaining and thus was chosen for quantitative densitometry. Results In hypertensive patients, the area occupied by NPFF immunostained neuronal elements in the central sections through the suprachiasmatic nucleus (SCh), paraventricular hypothalamic nucleus (Pa), bed nucleus of the stria terminalis (BST), perinuclear zone (PNZ) of the supraoptic nucleus (SON), dorso- (DMH), ventromedial (VMH) nuclei, and perifornical nucleus (PeF) was dramatically decreased compared to controls, ranging about six times less in the VMH to 15 times less in the central part of the BST (BSTC). The NPFF innervation of both nonstained neuronal profiles and microvasculature was extremely poor in hypertensive patients compared to control. Conclusions The decreased NPFF expression in the hypothalamus of hypertensive patients might be a cause of impairment of its interaction with other neurochemical systems, and thereby might be involved in the pathogenesis of the disease.

    Pulse wave velocity (PWV) has been shown to influence the effects of antihypertensive drugs in the prevention of cardiovascular diseases. Data are limited on whether PWV is an independent predictor of stroke above and beyond hypertension control. This longitudinal analysis examined the independent and joint effect of brachial-ankle PWV (baPWV) with hypertension control on the risk of first stroke. This report included 3310 hypertensive adults, a subset of the China Stroke Primary Prevention Trial (CSPPT) with baseline measurements for baPWV. During a median follow-up of 4.5 years, 111 participants developed first stroke. The risk of stroke was higher among participants with baPWV in the highest quartile than among those in the lower quartiles (6.3% versus 2.4%; hazard ratio, 1.66; 95% confidence interval, 1.06-2.60). Similarly, the participants with inadequate hypertension control had a higher risk of stroke than those with adequate control (5.1% versus 1.8%; hazard ratio, 2.32; 95% confidence interval, 1.49-3.61). When baPWV and hypertension control were examined jointly, participants in the highest baPWV quartile and with inadequate hypertension control had the highest risk of stroke compared with their counterparts (7.5% versus 1.3%; hazard ratio, 3.57; 95% confidence interval, 1.88-6.77). There was a significant and independent effect of high baPWV on stroke as shown among participants with adequate hypertension control (4.2% versus 1.3%; hazard ratio, 2.29, 95% confidence interval, 1.09-4.81). In summary, among hypertensive patients, baPWV and hypertension control were found to independently and jointly affect the risk of first stroke. Participants with high baPWV and inadequate hypertension control had the highest risk of stroke compared with other groups. PMID:27217412

    Hypertension is a large and growing public health problem worldwide. Hyperuricemia and overweight/obesity are two of the most important risk factors for hypertension. However, their combined effect on the risk of hypertension is not known. Participants aged 20 years and older from the National Health and Nutrition Examination Survey from 1999-2012 were used to evaluate the separate and combined effects of hyperuricemia and overweight/obesity on the risk of prevalent hypertension among different race, gender and age groups. Participants (31,473) were used to estimate separate and combined effects on the prevalence of hypertension. The overall prevalence of hypertension among adults with a combination of hyperuricemia and overweight/obesity (50.2%, 95% confidence interval (CI) 48.3-52.1%) was significantly higher than separate hyperuricemia (41.7%, 95% CI 37.2-46.2%) and overweight/obesity (30.6%, 95% CI 29.5-31.8%). The magnitude of odds ratio (OR) from the combination of hyperuricemia and overweight/obesity (OR=4.53, 95% CI 4.05-5.07) was significantly higher than both hyperuricemia (OR=2.62, 95% CI 2.07-3.32) and overweight/obesity (OR=2.08, 95% CI 1.89-2.30). Combined effect of hyperuricemia and overweight/obesity on the risk of hypertension is much stronger than any separate one. These data can provide important information for identification of target populations for future intervention and patient management.

    Background Current scientific evidence addressing the relation between periodontitis and hypertension is limited to a few studies producing inconsistent results. Methods All participants of an on-going representative cohort of Puerto Rican elderly who were 70 years and older and residing in San Juan metropolitan area were invited to this cross-sectional study. Periodontal probing depth (PD) and attachment loss (AL) were summarized using CDC-AAP definition for severe periodontitis (≥2 teeth with AL ≥6mm and ≥1 tooth with PD ≥5mm). We averaged three repeated blood pressure (BP) measurements taken using a standardized auscultatory method. Information on hypertension history, use of anti-hypertensive medications and potential confounders (age, gender, smoking, heavy and binge drinking, diabetes, utilization of preventive dental services, flossing, body mass index, fruit and vegetable, whole wheat bread and high-fiber cereal consumption) was collected during in-person interviews. High BP was defined as average systolic BP ≥140 mmHg or diastolic ≥90 mmHg. Multivariate logistic regression models were used to study the relation between severe periodontitis, hypertension history and high BP. Results The study population comprised 182 adults. In multivariate analysis, there was no association between severe periodontitis and hypertension history (OR=0.99, 95% CI: 0.40–2.48). Severe periodontitis was associated with high BP, with OR of 2.93 (95% CI: 1.25–6.84), after adjusting for age, gender, smoking, and binge drinking. This association was stronger when restricted to those with hypertension or taking anti-hypertensive medications: OR=4.20 (95% CI: 1.28–13.80). Conclusion Our results suggest that periodontitis may contribute to poor blood pressure control among older adults. PMID:22548584

    2015-09-01

    High altitude exposure during leisure time is becoming more and more frequent. Due to the high prevalence of hypertension in the general population, high altitude exposure in hypertensive patients may not be uncommon. The increase in blood pressure with altitude has been confirmed by ambulatory blood pressure measurement in normotensive as well as in hypertensive patients. Compared to a placebo, most hypertensive drugs keep their blood pressure lowering effect up to a certain altitude. It is recommended that hypertensive patients measure their blood pressure during high altitude, exposure and plan a possible adaptation of treatment with their physician before their sojourn.

    The disproportionately high prevalence of hypertension and its associated mortality and morbidity in minority older adults is a major public health concern in the United States. Despite compelling evidence supporting the beneficial effects of therapeutic lifestyle changes on blood pressure reduction, these approaches remain largely untested among minority elders in community-based settings. The Counseling Older Adults to Control Hypertension trial is a two-arm randomized controlled trial of 250 African-American and Latino seniors, 60 years and older with uncontrolled hypertension, who attend senior centers. The goal of the trial is to evaluate the effect of a therapeutic lifestyle intervention delivered via group classes and individual motivational interviewing sessions versus health education, on blood pressure reduction. The primary outcome is change in systolic and diastolic blood pressure from baseline to 12 months. The secondary outcomes are blood pressure control at 12 months; changes in levels of physical activity; body mass index; and number of daily servings of fruits and vegetables from baseline to 12 months. The intervention group will receive 12 weekly group classes followed by individual motivational interviewing sessions. The health education group will receive an individual counseling session on healthy lifestyle changes and standard hypertension education materials. Findings from this study will provide needed information on the effectiveness of lifestyle interventions delivered in senior centers. Such information is crucial in order to develop implementation strategies for translation of evidence-based lifestyle interventions to senior centers, where many minority elders spend their time, making the centers a salient point of dissemination.

    Idiopathic intracranial hypertension is a difficult condition to manage. We present a novel treatment that substantially improved the headaches and reduced admissions and shunt revision surgery in a patient. We inserted a ventriculoperitoneal shunt, performed subtemporal craniectomies, and instructed our patient to apply different sized headbands to allow her to anticipate and control her own intracranial pressure: a tight headband for low-pressure headaches; no band for high-pressure headaches. Magnetic resonance imaging and intracranial pressure monitoring revealed this was not a placebo effect.

    A group of essential hypertension patients (n equals 168) and a group of unselected controls (n equals 302) completed a questionaire constructed to measure perceived threat and rating-scales to judge the emotional atmosphere of personal childhood experiences. The patients do not regard their present life-situations as more threatening than the controls and they report more pleasant childhood memories than the controls. These results contradict those obtained in previous work which may be due to the relative lack of emphasis placed on coping variables in the present study.

    Objective Resistant hypertension (res-HTN) is a challenging problem, but little is known of res-HTN in patients with coronary artery disease (CAD). In this post-hoc INternational VErapamil SR-Trandolapril STudy (INVEST) analysis, we assessed prevalence, predictors, and impact on outcomes of res-HTN in CAD patients with hypertension. Methods Participants (n=17 190) were divided into three groups according to achieved blood pressure (BP): controlled (BP <140/90 mmHg on three or fewer drugs); uncontrolled (BP ≥140/90mmHg on two or fewer drugs); or resistant (BP ≥140/90 mmHg on three drugs or any patient on at least four drugs). Results The prevalence of res-HTN was 38%: significant predictors of res-HTN included heart failure [odds ratio (OR) 1.73], diabetes (OR 1.63), Black race (OR 1.50), and US residence (OR 1.50). Compared with controlled HTN, res-HTN had multivariate-adjusted association with higher risk of adverse outcomes {first occurrence of all-cause death, nonfatal myocardial infarction, or nonfatal stroke [hazard ratio 1.27, 95% confidence interval (CI) 1.13–1.43], and individual outcomes of all-cause death (hazard ratio 1.29, 95% CI 1.13–1.48), cardiovascular mortality (hazard ratio 1.47, 95% CI 1.21–1.78), and nonfatal stroke (hazard ratio 1.61, 95% CI 1.17–2.22), but not nonfatal myocardial infarction (hazard ratio 0.98, 95% CI 0.72–1.34)}. Adverse outcomes, except nonfatal stroke, did not differ in patients with res-HTN compared to uncontrolled HTN. Conclusions Res-HTN is common in patients with CAD and hypertension, associated with poor prognosis, and linked with a number of conditions. Emphasis should be placed on recognizing those at risk for res-HTN and future studies should examine whether more aggressive treatment of res-HTN improves outcomes. PMID:24299915

    Idiopathic intracranial hypertension (IIH) is a rare but important disease associated with significant morbidity. There is an expected rise in prevalence in line with the escalating global burden of obesity. Modern revisions in the terminology and diagnostic criteria for IIH help guide clinicians in investigations and researchers in standardising recruitment criteria for clinical trials. The pathophysiology of IIH is incompletely characterised; suggested underpinning mechanisms include the role of cerebrospinal fluid regulation as well as metabolic and endocrinological perspectives. Recent treatment trials are providing insights into the management but debate still surrounds key areas in treatment. This review will provide an up-to-date discussion on the potential pathogenic mechanisms and management of IIH. PMID:26888960

    Objectives: To analyze the predictive value of new cardiovascular (CV) risk factors for CV risk assessment in the adult Romanian hypertensive (HT) population. Methods: Hypertensive adults aged between 40-65 years of age, identified in national representative SEPHAR II survey were evaluated by anthropometric, BP and arterial stiffness measurements: aortic pulse wave velocity (PWVao), aortic augmentation index (AIXao), revers time (RT) and central systolic blood pressure (SBPao), 12 lead ECGs and laboratory workup. Values above the 4th quartile of mean SBP' standard deviation (s.d.) defined increased BP variability. Log(TG/HDL-cholesterol) defined atherogenic index of plasma (AIP). Serum uric acid levels above 5.70 mg/dl for women and 7.0 mg/dl for males defined hyperuricemia (HUA). CV risk was assessed based on SCORE chart for high CV risk countries. Binary logistic regression using a stepwise likelihood ratio method (adjustments for major confounders and colliniarity analysis) was used in order to validate predictors of high and very high CV risk class. Results: The mean SBP value of the study group was 148.46±19.61 mmHg. Over forty percent of hypertensives had a high and very high CV risk. Predictors of high/very high CV risk category validated by regression analysis were: increased visit-to-visit BP variability (OR: 2.49; 95%CI: 1.67-3.73), PWVao (OR: 1.12; 95%CI: 1.02-1.22), RT (OR: 0.95; 95% CI: 0.93-0.98), SBPao (OR: 1.01; 95%CI: 1.01-1.03) and AIP (OR: 7.08; 95%CI: 3.91-12.82). Conclusion: The results of our study suggests that the new CV risk factors such as increased BP variability, arterial stiffness indices and AIP are useful tools for a more accurate identification of hypertensives patients at high and very high CV risk.

    Hypertension awareness, treatment, and control are lower among uninsured than insured adults. Time trends in differences and underlying modifiable factors are important for informing strategies to improve health equity. National Health and Nutrition Examination Surveys 1988 to 1994, 1999 to 2004, and 2005 to 2010 data in adults aged 18 to 64 years were analyzed to explore this opportunity. The proportion of adults with hypertension who were uninsured increased from 12.3% in 1988 to 1994 to 17.4% in 2005 to 2010. In 1988 to 1994, hypertension awareness, treatment, and control to <140/<90 mm Hg (30.1% versus 26.5%; P=0.27) were similar in insured and uninsured adults. By 2005 to 2010, the absolute gap in hypertension control between uninsured and insured adults of 21.9% (52.5% versus 30.6%; P<0.001) was explained approximately equally by lower awareness (65.2% versus 80.7%), fewer aware adults treated (75.2% versus 88.5%), and fewer treated adults controlled (63.1% versus 73.5%; all P<0.001). Publicly insured and uninsured adults had similar income. Yet, hypertension control was similar across time periods in publicly and privately insured adults, despite lower income and education in the former. In multivariable analysis, hypertension control in 2005 to 2010 was associated with visit frequency (odds ratio, 3.4 [95% confidence interval, 2.4-4.8]), statin therapy (1.8 [1.4-2.3]), and healthcare insurance (1.6 [1.2-2.2]) but not poverty index (1.04 [0.96-1.12]). Public or private insurance linked to more frequent healthcare, greater awareness and effective treatment of hypertension, and appropriate statin use could reverse a long-term trend of growing inequity in hypertension control between insured and uninsured adults.

    Incidence rates for stroke and hypertension are higher in black ethnic groups of African descent in the USA and UK than in white groups, suggesting a need for targeted intervention. We conduct a narrative review of published research evidence on community interventions to manage hypertension among black ethnic groups, and explore the concept of cultural sensitivity in these interventions. Data sources comprised computer-aided searches of published studies over the years 1981 to March 2006, on community strategies for improving hypertension control targeting black groups, and further references from these articles. Twenty-seven relevant studies were identified. Health education was associated with improvements in knowledge about hypertension, while education combined with individualised support for patients to self-manage hypertension, including goal setting and monitoring to enhance patient self-management of hypertension, and family support in managing hypertension were associated with reductions in blood pressure levels and improvements in blood pressure control. Collaboration with black communities, using local or minority ethnic staff, conducting preliminary research with target groups to investigate perceptions and canvass ideas for the intervention design were common methods assumed to achieve cultural sensitivity. Studies, however, provided insufficient robust evidence of the effectiveness of these strategies in terms of quantifiable outcomes, although this criterion is contested, with social justice arguments being offered instead. Implicit assumptions about homogeneity and shared interests within the 'community', and representation of 'community' views have implications for the effectiveness of interventions. These findings highlight areas for the future development of interventions to reduce hypertension rates in black groups, and factors that need to be robustly investigated and explicitly addressed in intervention design.

    The typical assumption is that patients with CKD will have progressive nephropathy. Methodological issues, such as measurement error and regression to the mean, have made it difficult to document whether kidney function might improve in some patients. Here, we used data from 12 years of follow-up in the African American Study of Kidney Disease and Hypertension to determine whether some patients with CKD can experience a sustained improvement in GFR. We calculated estimated GFR (eGFR) based on serum creatinine measurements during both the trial and cohort phases. We defined clearly improved patients as those with positive eGFR slopes that we could not explain by random measurement variation under Bayesian mixed-effects models. Of 949 patients with at least three follow-up eGFR measurements, 31 (3.3%) demonstrated clearly positive eGFR slopes. The mean slope among these patients was +1.06 (0.12) ml/min per 1.73 m2 per yr, compared with −2.45 (0.07) ml/min per 1.73 m2 per yr among the remaining patients. During the trial phase, 24 (77%) of these 31 patients also had clearly positive slopes of 125I-iothalamate–measured GFR during the trial phase. Low levels of proteinuria at baseline and randomization to the lower BP goal (mean arterial pressure ≤92 mmHg) associated with improved eGFR. In conclusion, the extended follow-up from this study provides strong evidence that kidney function can improve in some patients with hypertensive CKD. PMID:22402803

    Gleerup, G; Winther, K

    1996-01-01

    In this study the authors examine whether smoking further heightens platelet activity and reduces fibrinolysis above that already present in mild hypertension. Ten smokers and 11 non-smokers, all with mild hypertension (defined as a diastolic pressure between 90 and 110 mm Hg) were compared for their platelet activity in vitro and in vivo and for their fibrinolytic activity. Successive measurements were made with the patients lying at rest after they had assumed the erect posture for 10 min and at the end of a 5-min moderately strenuous exercise test. The threshold for platelet aggregation by ADP in vitro was significantly lower in samples taken from the smokers at rest (1.4 +/- 0.9 mumol L(-1)) than in the non-smokers (3.5 +/- 2.5 mumol L(-1)), and the difference persisted both in the upright posture and after exercise. The level of platelet release of beta-thromboglobulin was, likewise, higher in the smokers in the upright posture. Neither standing up nor physical exercise had any significant influence on either of these two indices of platelet activity. The euglobulin clot lysis time was slightly longer in the smokers than in the non-smokers in all three experimental situations, but the differences were not significant. Inhibitor of tissue plasminogen activator was not materially different in the two groups (Table 2). The results indicate that smoking adds a further element of heightened platelet activity to that inherently present in hypertension.

    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

    BACKGROUND Idiopathic noncirrhotic portal hypertension (INCPH) is a rare disease characterized by increased portal venous pressure in the absence of cirrhosis and other causes of liver diseases. The aim of the present study was to present our results in using portosystemic shunt surgery in patients with INCPH. MATERIAL AND METHODS Patients who had been referred to our Liver Transplantation Institute for liver transplantation and who had undergone surgery from January 2010 to December 2015 were retrospectively analyzed. Patients with INCPH who had undergone portosystemic shunt procedure were included in the study. Age, sex, symptoms and findings, type of portosystemic shunt, and postoperative complications were assessed. RESULTS A total of 1307 patients underwent liver transplantation from January 2010 to December 2015. Eleven patients with INCPH who did not require liver transplantation were successfully operated on with a portosystemic shunt procedure. The mean follow-up was 30.1±19 months (range 7-69 months). There was no mortality in the perioperative period or during the follow-up. Two patients underwent surgery again due to intra-abdominal hemorrhage; one had bleeding from the surgical site except the portacaval anastomosis and the other had bleeding from the h-graft anastomosis. No patient developed encephalopathy and no patient presented with esophageal variceal bleeding after portosystemic shunt surgery. Shunt thrombosis occurred in 1 patient (9.9%). Only 1 patient developed ascites, which was controlled medically. CONCLUSIONS Portosystemic shunt surgery is a safe and effective procedure for the treatment of patients with INCPH. PMID:27194018

    Results from studies involving exposure to road traffic noise and risk of hypertension are diverse and have seldom reached statistical significance. This study was designed with the aim of investigating whether there is any association between road traffic noise and prevalence of hypertension in an urban adult population. Similar studies have never been reported from India. A cross-sectional study was performed on 909 adults (533 female and 376 male) aged 18-80 years residing in close proximity to roadways in Asansol City. Time-weighted equivalent noise level (L den) was estimated using a standard modeling platform. Odds for hypertension in relation to traffic noise exposure were estimated by univariate and multifactorial logistic regression. The adjusted odds ratio (OR) for self-reported hypertension was 1.99 (95 % confidence interval (CI) 1.66-2.39) per 5 dB(A) increase of L den (range 55.1-77.9). A gender-related risk difference was observed among the male (OR 1.81 (1.42-2.31)) and female (OR 2.18 (1.66-2.88)) respondents. For increase in 9 years of age, the odds of hypertension risk increased by 60 % (OR 1.66 (1.43-1.91) among those exposed above L den 60 dB(A). Vulnerable subgroups were female aged 35-54 years and male aged 45-54 years. The study suggests that a threshold exposure to road traffic noise at L den > 65 dB(A) for men and L den > 60 dB(A) in women may be associated with the occurrence of hypertension.

    The purpose of this study was to evaluate the influence of different factors, among them left ventricular hypertrophy (LVH) on long-term heart rate variability (HRV) in patients with hypertension. 38 patients with arterial hypertension of different genesis were included in the study. Ischemia was excluded in all the patients by the data of clinical and instrumental methods of investigation. LVH data obtained from HRV of 20 healthy subjects was used as control. HRV was evaluated by estimating variations for short intervals of a rhythmogram (VSI). A HRV decrease did not depend on sex, but essentially depended on patients'a age, disease duration and the form of hypertension. A marked tendency leading to the rate variability decrease was observed only in moderate LVH. In cases of original LVH variability data did not differ from those in patients without signs of LVH. Low or marginal HRV was more often observed in patients with essential hypertension and in those with hypertension of endocrine genesis. As far as renal hypertension is concerned low variability was less frequent. There were a lot of factors which affect the change of HRV. The more significant of them were the patients' age, hypertension genesis and form of hypertension. Factors leading to the rate variability decrease were the following age above 40, endocrine or essential hypertension and moderate form of hypertension.

    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

    We previously reported that gestational dietary protein restriction in rats causes gender-related differences in development of offspring's blood pressure (BP) that is more pronounced in the males than females. Since such effects may depend on sex hormones, we investigated the role of estradiol in the development of hypertension in female offspring of protein restricted dams. Female offspring of pregnant rats fed normal (20%) or protein restricted (6%) casein diets throughout pregnancy were kept either, intact, ovariectomized or ovariectomized with estradiol supplementation. BP, estradiol and testosterone levels and vascular estrogen receptor (ER) were examined. BP was significantly higher and plasma estradiol levels were significantly lower by 34% in intact protein restricted female offspring compared to corresponding controls. Further decrease in estradiol levels by ovariectomy exacerbated hypertension in the protein restricted females with an earlier onset and more prominent elevation in BP compared to controls. Estradiol supplementation in ovariectomized protein restricted females significantly reversed ovariectomy-induced hypertension but did not normalize BP to control levels. The hypertensive protein restricted females have reduced vascular ERα expression that was unaffected by ovariectomy or estradiol replacement. In addition, the testosterone levels were significantly higher by 2.4-, 3.4-, and 2.8-fold in intact, ovariectomized and estradiol replaced protein restricted females compared to corresponding controls. Our data show that: 1) hypertension in protein restricted adult female offspring is associated with reduced plasma estradiol levels, 2) estradiol protects and limits the severity of hypertension in protein restricted females and contribute for sexual dimorphism, and 3) Estradiol replacement fails to completely reverse hypertension, which may be related to limited availability of vascular ERα receptors and/or increased circulating testosterone

    This multicenter study, conducted to determine the antihypertensive efficacy of bevantolol at different fixed doses compared with placebo was carried out at four separate institutions using a common protocol. One hundred thirty-nine patients with mild to moderate essential hypertension were enrolled. At doses of 200 to 400 mg/day bevantolol was clearly effective in lowering diastolic blood pressure and in maintaining this effect over the eight weeks of this double-blind study. Twice a day dosing is indicated since efficacy was evident 12 hours post-dosing. Bevantolol was well tolerated.

    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.

    Observational studies have conveyed the connection between hypertension and cognitive impairment. Several forms of dementia are more frequent in hypertensive subjects or those with previous history of hypertension compared to subjects with normal blood pressure.In many studies, hypertension occuring in mid-life is a risk factor of dementia occuring in later age. Long-standing hypertension will induce structural damages in the brain. It is also widely known that hypertension attributes to small vessel diseases causing lacunar infarcts and white matter lesions associated with cognitive decline. Due to availability and for cost efficiencies, widespread use of MRI in the evaluation of elderly with hypertension is limited. Nevertheless, silent brain infarctions should be sought in all hypertensives patients with neurological deficits and memory loss in particular. As cognitive disturbances are hypertension-related in some parts, suitable cognitive evaluation tests should be warranted in the clinical assessment of all hypertensive patients with cognitive complaints and in all elderly with hypertension. Hypertension is related with impairments in several cognitive domains like attention, language, short & long term memory, visuo-spatial and executive functions. PMID:27643255

    [Purpose] The aim of this study was to investigate whether hypertension negatively affects the postural balance control of elderly adults under different sensory conditions. [Subjects and Methods] Fifty-four healthy elderly adults who were residents in a Geriatric Home Care Center were recruited for this study. Height, weight, body mass index and age of the volunteers were recorded. After applying the exclusion criteria, the final study group included 16 hypertensive (HT) and the control group included 10 non-hypertensive (Non-HT) healthy elderly adults. To evaluate postural balance control objectively, the modified Clinical Test of Sensory Interaction on Balance (modified CTSIB) test was performed under four different conditions: 1) eyes open on a stable surface; 2) eyes closed on a stable surface; 3) eyes open on an unstable surface; and 4) eyes closed on an unstable surface. [Results] The postural balance scores (center of gravity sway) of the HT group were slightly higher than those of the Non-HT group under conditions 1 (HT group=0.3°/sec, Non-HT group=0.2°/sec), 2 (HT group=0.8°/sec, Non-HT group=0.4°/sec) and 4 (HT group=4.5°/sec, Non-HT group=3.5°/sec), but no statistically significant differences were found between the HT and Non-HT groups under any sensory condition. [Conclusion] The result of this study indicate that controlled hypertension in elderly adults is not a cause of worse balance performance than controls on stable or unstable surfaces with the eyes open or closed.

    This review will discuss the medical management of pulmonary hypertension in patients with left ventricular assist devices. Although much has been written on the management of primary pulmonary hypertension, also called pulmonary arterial hypertension, this review will instead focus on the treatment of pulmonary hypertension secondary to left heart disease. The relevant pharmacotherapy can be divided into medications for treating heart failure, such as diuretics and β-blockers, and medications for treating pulmonary hypertension. We also discuss important preoperative considerations in patients with pulmonary hypertension; the relationships between left ventricular assist devices, pulmonary hemodynamics, and right heart failure; as well as optimal perioperative and long-term postoperative medical management of pulmonary hypertension.

    Nondippers (people whose sleep systolic blood pressure (SBP) fails to decrease >10% from daytime SBP) have increased risk of cardiovascular disease. The prevalence of nondipping in younger adults has not been well-studied, nor has its value for predicting hypertension. We examined the prevalence of nondipping in a sub-study of the Coronary Artery Risk Development in Young Adults (CARDIA) Study. We used Cox regression to estimate the hazard ratio (HR) conferred by nondipping for incident prehypertension or hypertension (preHTN/HTN) over 15 years. Of the 264 non-hypertensive participants at baseline, 118 (45%) were nondippers. Blacks were more likely than Whites to be nondippers (52% vs 33%, p=0.004). The incidence rate of preHTN/HTN was 29.2/1000 person-years among dippers and 36.2/1000 person-years among nondippers. Compared to those in the lowest quartile of nighttime to daytime SBP, those in the highest quartile were more likely to develop preHTN/HTN (HR 1.61; p =0.06), but this relationship was attenuated after adjustment (HR 1.34; p =0.27). Our results demonstrate that nondipping is common in young, nonhypertensive adults, and is more common in Blacks than Whites. Nondipping might predate a meaningful clinically detected increase in BP in some people, but more research in larger study samples is needed. PMID:21269909

    Objectives: Epidemiologic studies have shown that chronic short sleep may be associated with the development of hypertension; however, the results are controversial. This meta-analysis was conducted to determine whether the duration of sleep is associated with hypertension. Methods: Reference databases (PubMed, EmBase, the Cochrane Library, Chinese Biological Medicine database) were searched for studies related to sleep duration and hypertension. Sleep duration categories (≤ 5 h, 6 h, 7 h, 8 h, ≥ 9 h) and prevalence or incidence of hypertension in each sleep category were extracted. A general analysis and subgroup analyses stratified by gender, age, study design, and different definitions of sleep duration were conducted to evaluate the relationship between sleep duration and hypertension. Results: Thirteen articles out of a total of 1,628 articles involving 347,759 participants met the inclusion criteria. A U-shaped change in pooled odds ratios (ORs) for hypertension due to the change of sleep duration was observed. The unadjusted OR for hypertension of individuals who slept ≤ 5 h vs 7 h was 1.61, 95% CI = 1.28–2.02; those who slept ≥ 9 h vs 7 h was 1.29, 95% CI = 0.97–1.71. The pooled ORs were still significant after adjusted by age and gender. Women deprived of sleep (sleep time ≤ 5 h vs 7 h, OR = 1.68, 95% CI = 1.39–2.03) had a higher risk of hypertension than men (OR = 1.30, 95% CI = 0.93–1.83). Conclusion: Excessively longer and shorter periods of sleep may both be risk factors for high blood pressure; these associations are stronger in women than men.

    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

    2010-01-01

    A growing body of evidence indicates that the metabolic syndrome and hypertension are interrelated at an epidemiological as well as pathophysiological level. Due to the high prevalence of concomitant signs of subclinical organ damage and the high risk of cardiorenal complications, hypertensive patients with metabolic syndrome are to be considered at high risk. Although the management of this condition must begin with the implementation of a healthy lifestyle and dietary habits, these measures are usually insufficient to adequately control blood pressure values and reduce the cardiovascular risk in the long term. Therefore, in the presence of persistent blood pressure values above 140/90 mmHg, pharmacological antihypertensive therapy is often required to reach the recommended target of less than 130/80 mmHg. In the absence of specific, compelling indications to the contrary, inhibitors of the renin-angiotensin system and calcium-channel blockers should be preferred over diuretics and beta-blockers. However, diuretics, preferably at a low dosage, are often necessary to obtain satisfactory blood pressure control. The combination of diuretics and beta-blockers should be avoided, if possible, in patients with prediabetes or diabetes.

    An opioid mechanism may help explain hypertensive hypoalgesia. A double-blind placebo-controlled design compared the effects of opioid blockade (naltrexone) and placebo on electrocutaneous pain threshold, pain tolerance, and retrospective McGill Pain Questionnaire ratings in 35 unmedicated patients with essential hypertension and 28 normotensive individuals. The hypertensives experienced less pain than normotensives during the assessment of their pain tolerance; however, this manifestation of hypertensive hypoalgesia was not moderated by naltrexone. These findings fail to support the hypothesis that essential hypertension is characterised by relative opioid insensitivity. PMID:18031920

    Background Hypertension is the 3rd cause of death accounting for one in eight deaths worldwide. Hypertension was thought to be rare in Africa, but it is now recognized as one of the most important cerebrovascular diseases contributing to about 40% of these diseases in the continent. The aims of this study were to describe the pattern of blood pressure distribution among adults, and determine prevalence of prehypertension and hypertension among adults in Northern Ethiopia. Method The study was done on a community-based sample of 1183 adults of 697 (58.8%) urban and 486 (41.1%) rural residents using statistical multistage sampling procedures. The study was based on the recent WHO and JNC-7 classification of blood pressure. Multi-item structured questionnaires were also developed to elicit additional information on the subjects. Results The overall prevalence of hypertension and prehypertension in the study population was 18.1% and 37.2%, respectively. The prevalence of hypertension positively correlated with body mass index and age in both urban and rural residents (P = 0.001). Sex and age adjusted mean systolic blood pressure (SBP) was statistically higher in urban than in rural population (P = 0.001). Conclusion Hypertension was found to have high prevalence in the study region. However, people’s awareness and control of hypertension was found to be very poor. Lack of a clear hypertension prevention guidelines and strategies nationwide can aggravate the impact of cardiovascular diseases. PMID:24592854

    The maternal system is challenged with many physiological changes throughout pregnancy to prepare the body to meet the metabolic needs of the fetus and for delivery. Many pregnancies, however, are faced with pathological stressors or complications that significantly impact maternal health. A shift in this paradigm is now beginning to investigate the implication of pregnancy complications on the fetus and their continued influence on offspring disease risk into adulthood. In this investigation, we sought to determine whether maternal hypertension during pregnancy alters the cerebral response of adult offspring to acute ischemic stroke. Atrial natriuretic peptide gene-disrupted (ANP(-/-)) mothers exhibit chronic hypertension that escalates during pregnancy. Through comparison of heterozygote offspring born from either normotensive (ANP(+/-WT)) or hypertensive (ANP(+/-KO)) mothers, we have demonstrated that offspring exposed to maternal hypertension exhibit larger cerebral infarct volumes following middle cerebral artery occlusion. Observation of equal baseline cardiovascular measures, cerebrovascular structure, and cerebral blood volumes between heterozygote offspring suggests no added influences on offspring that would contribute to adverse cerebral response post-stroke. Cerebral mRNA expression of endothelin and nitric oxide synthase vasoactive systems demonstrated up-regulation of Et-1 and Nos3 in ANP(+/-KO) mice and thus an enhanced acute vascular response compared to ANP(+/-WT) counterparts. Gene expression of Na(+)/K(+) ATPase channel isoforms, Atp1a1, Atp1a3, and Atp1b1, displayed no significant differences. These investigations are the first to demonstrate a fetal programming effect between maternal hypertension and adult offspring stroke outcome. Further mechanistic studies are required to complement epidemiological evidence of this phenomenon in the literature. PMID:26169981

    Renal vascular damage caused by arterial hypertension participates in the alterations to systemic vascular function and structure. Nephrosclerosis seems to run in parallel with systemic atherosclerosis, which accounts for the increased cardiovascular morbidity and mortality seen in hypertensive patients. Parameters indicating the existence of an alteration in renal function (increased serum creatinine, proteinuria and microalbuminuria) are independent predictors for an increased cardiovascular morbidity and mortality. Hence, parameters of renal function have to be considered in any stratification of cardiovascular risk in hypertensive patients.

    between the east and south, west and City of Zagreb should be investigated. In the high blood pressure group, 76.5% of subjects had a body mass index greater than 25 and 48% ofthose with inadequate physical activity, both exceeding the rates recorded in persons with normal blood pressure. Whereas 58.6% of the subjects knew they had elevated blood pressure, 48.4% of them were taking their therapy, and only 14.8% kept their blood pressure under control (systolic <140 mm Hg and diastolic <90 mm Hg). Arterial hypertension is a major public health problem in all regions of Croatia. The available literature data suggest that the Croatia's share of individuals with high blood pressure is comparable to that in industrialized countries of continental Europe. The prevention of excessive body weight, also through increased physical activity of the population and changes in poor dietary habits, remains the essential element in planning primary prevention programs for high blood pressure. Raising the population's awareness of the problem, early detection of high blood pressure and encouraging the population to take regular therapy for high blood pressure, along with the adoption of healthy lifestyle are important factors in achieving effective control and alleviating the consequences of hypertension.

    Recent studies suggested that nocturnal variations of blood pressure (BP) were closely related to type 2 diabetes. However, little information has been revealed about the relationship between reverse-dipper pattern of BP and type 2 diabetes. In this cross-sectional study, BP variations of 531 hypertensive patients were evaluated with ambulatory BP monitoring (ABPM). Diagnosis of diabetes in Chinese adults was made according to diabetes diagnostic criteria of 2015. Multivariate logistic regression was used to examine the relationships between type 2 diabetes and ABPM results. In the study, patients with reverse-dipper pattern (32.3%) had the highest prevalence of type 2 diabetes compared with dippers (21.4%) and nondippers (23.3%). After multivariate logistic regression, reverse-dipper BP pattern (OR 2.067, P = 0.024) and nondipper BP pattern (OR 1.637, P = 0.039) were found to be correlated with type 2 diabetes compared with dipper pattern. The results of our study also suggested that type 2 diabetes might contribute to the reverse-dipper pattern of BP (OR 1.691, P = 0.023). In addition, fasting glucose was negatively correlated with the decline rate of nocturnal SBP (r = -0.095, P = 0.029). Reverse-dipper pattern of BP in ABPM may be independently associated with type 2 diabetes in patients with hypertension. PMID:27109832

    During 2006, new evidence supporting the need to adopt a global approach to the treatment of cardiovascular risk in hypertensive patients has been reported. It is increasingly clear that it is not sufficient to aim for optimum blood pressure control, which in any case is not easy to achieve, and that it is essential to treat all cardiovascular risk factors by using drugs with proven benefits, even when those benefits are supplementary to the drug's principal effects. In addition, drugs that could have a detrimental effect or that are, merely, less beneficial should be avoided or kept as a last resort. This appears to have happened with atenolol, and with beta-blockers in general, which have been withdrawn as first-line treatment in the recommendations of some professional societies. To lower cardiovascular risk, it is essential to prevent the development of conditions like diabetes, which are known to have drastic effect on the patient's prognosis. Recently, the results of the DREAM study, which are discussed in detail in this article, have been reported. They could lead to a change in therapeutic strategy in patients who are expected to develop diabetes. In addition, this year has seen the publication of substantial data on a new antihypertensive agent, aliskiren, the first oral renin inhibitor. It is awaiting approval by the international medicine agencies (i.e., the FDA and the EMEA), but should provide a very promising tool in the difficult area of high blood pressure management. Despite numerous advances in the pharmacologic treatment of high blood pressure, control is very difficult to achieve, principally in the elderly, in whom the prevalence of hypertension is high. In these patients, social factors and difficulties with treatment compliance also have an influence and must be dealt with by public health measures aimed at improving blood pressure control.

    This retrospective, multicentre study evaluated patients with lymphangioleiomyomatosis (LAM) and pre-capillary pulmonary hypertension (PH) by right heart catheterisation. It was conducted in 20 females with a mean ± SD age of 49 ± 12 yrs and a mean ± SD time interval between LAM and PH diagnoses of 9.2 ± 9.8 yrs. All, except for one patient, were receiving supplemental oxygen. 6-min walking distance was mean ± SD 340 ± 84 m. Haemodynamic characteristics were: mean pulmonary artery pressure (PAP) 32 ± 6 mmHg, cardiac index 3.5 ± 1.1 L · min(-1) · m(-2) and pulmonary vascular resistance (PVR) 376 ± 184 dyn · s · cm(-5). Mean PAP was >35 mmHg in only 20% of cases. The forced expiratory volume in 1 s was 42 ± 25%, carbon monoxide transfer factor was 29 ± 13%, and arterial oxygen tension (P(a,O(2))) was 7.4 ± 1.3 kPa in room air. Mean PAP and PVR did not correlate with P(a,O(2)). In six patients who received oral pulmonary arterial hypertension (PAH) therapy, the PAP decreased from 33 ± 9 mmHg to 24 ± 10 mmHg and the PVR decreased from 481 ± 188 dyn · s · cm(-5) to 280 ± 79 dyn · s · cm(-5). The overall probability of survival was 94% at 2 yrs. Pre-capillary PH of mild haemodynamic severity may occur in patients with LAM, even with mild pulmonary function impairment. PAH therapy might improve the haemodynamics in PH associated with LAM.

    Multimorbidity has become the norm worldwide as populations age. It remains, however, infrequently researched. This study evaluated factors associated with multimorbidity in a predominantly Chinese hypertensive population. We included all adult patients prescribed their first antihypertensive agents in the entire public sector in Hong Kong from a validated database. Multimorbidity was defined as having one or more medical conditions (cardiovascular diseases; respiratory diseases; diabetes or impaired fasting glucose; renal disease) in addition to hypertension. We studied the prevalence of multimorbidity and performed multinomial regression analyses to evaluate factors independently associated with multimorbidity. 223,286 hypertensive patients (average age of 59.9 years, SD 17.6) were included. The prevalence of having 0, 1 and ≥ 2 additional conditions was 59.6%, 32.8% and 7.5%, respectively. The most common conditions were cardiovascular disease (24.2%) and diabetes (23.0%), followed by respiratory disorders (14.6%) and renal disease (10.9%). Older age (>50 years), male sex, lower household income, receipt of social security allowance and suboptimal blood pressure control (>140 mmHg or >90 mmHg; >130 mmHg or >80 mmHg for diabetes patients; AOR = 3.38-4.49) were significantly associated with multimorbidity. There exists a synergistic effect among these variables as older (≥ 70 years), male patients receiving security allowance had substantially higher prevalence of multimorbidity (19.9% vs 7.5% among all patients). Multimorbidity is very common in hypertensive patients and its prevalence increased markedly with the presence of risk factors identified in this study. Hypertensive patients with multimorbidities should receive more meticulous clinical care as their blood pressure control tends to be poorer. PMID:25499379

    Background Hypertension is a common chronic disease among older adults, and is associated with medical complications and mortality. This study aimed to examine the effects of social network characteristics on the prevalence, awareness, and control of hypertension among older adults. Methods The Korean Social Life, Health, and Aging Project (KSHAP) interviewed 814 ≥ 60-year-old residents and their spouses from a rural township between December 2011 and March 2012 (response rate: 95%). We evaluated the data from 595 participants. Multivariate logistic regression models were used to assess the effects of network characteristics on hypertension. Results We observed strong sex-specific network effects on the prevalence, awareness, and control of hypertension. Among older women, network density was associated with hypertension awareness [odds ratio (OR): 2.63, 95% confidence interval (CI): 1.03–5.37] and control (OR: 1.72; 95% CI: 0.94–3.13). Among older men, large networks were associated with a lower prevalence of hypertension (OR: 0.75; 95% CI: 0.58–0.96). Compared to older women, older men with coarse networks exhibited better hypertension awareness (OR: 0.37; 95% CI: 0.14–0.95) and control (OR: 0.42; 95% CI: 0.19–0.91). Network size interacted with density for hypertension control (P = 0.051), with controlled hypertension being associated with large and course networks. Conclusions A large network was associated with a lower risk for hypertension, and a coarse network was associated with hypertension awareness and control among older men. Older women with dense networks were most likely to exhibit hypertension awareness and control. PMID:27605938

    Studies in hypertension (HTN) pharmacogenomics seek to identify genetic sources of variable antihypertensive drug response. Genetic association studies have detected single-nucleotide polymorphisms (SNPs) that link to drug responses; however, to understand mechanisms underlying how genetic traits alter drug responses, a biological interface is needed. Patient-derived induced pluripotent stem cells (iPSCs) provide a potential source for studying otherwise inaccessible tissues that may be important to antihypertensive drug response. The present study established multiple iPSC lines from an HTN pharmacogenomics cohort. We demonstrated that established HTN iPSCs can robustly and reproducibly differentiate into functional vascular smooth muscle cells (VSMCs), a cell type most relevant to vasculature tone control. Moreover, a sensitive traction force microscopy assay demonstrated that iPSC-derived VSMCs show a quantitative contractile response on physiological stimulus of endothelin-1. Furthermore, the inflammatory chemokine tumor necrosis factor α induced a typical VSMC response in iPSC-derived VSMCs. These studies pave the way for a large research initiative to decode biological significance of identified SNPs in hypertension pharmacogenomics. Significance Treatment of hypertension remains suboptimal, and a pharmacogenomics approach seeks to identify genetic biomarkers that could be used to guide treatment decisions; however, it is important to understand the biological underpinnings of genetic associations. Mouse models do not accurately recapitulate individual patient responses based on their genetics, and hypertension-relevant cells are difficult to obtain from patients. Induced pluripotent stem cell (iPSC) technology provides a great interface to bring patient cells with their genomic data into the laboratory and to study hypertensive responses. As an initial step, the present study established an iPSC bank from patients with primary hypertension and demonstrated

    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

    Objective: The present study aimed to estimate prevalence of hypertension among adults in rural remote areas of Xinjiang, China and evaluate the associated factors of hypertension. Methods: The survey was based on questionnaire interviews and clinical measurements of 11,340 individuals (≥18 years old), and was conducted during 2009–2010 via a stratified cluster random sampling method in the remote rural areas of Xinjiang, about 4407 km away from the capital Beijing. Hypertension was defined according to WHO/ISH criteria. Results: Systolic blood pressure (SBP) and diastolic blood pressure (DBP) of the population were (126.3 ± 21.4) and (80.9 ± 13.4) mmHg. Compared with Han nationality subjects, SBP and DBP of Kazakh nationality subjects were significantly high (p < 0.05), while the SBP and DBP of Uyghur subjects were significantly low (Kazakh: (128.7 ± 23.9) and (83.0 ± 14.6) mmHg, Uyghur: (123.6 ± 19.3) and (77.4 ± 12.7) mmHg, Han: (126.5 ± 20.5) and (82.6 ± 11.9) mmHg, p < 0.05). Prevalence of hypertension of the population was 32.1%, and was greater among Kazakhs and lower among Uyghur than Han (Kazakh: 36.9%, Uyghur: 26.1%, Han: 33.7%, p < 0.05). The age-standardized prevalence of hypertension was 30.2%, and was greater among Kazakhs while lower among Uyghurs than Han subjects (Kazakh: 37.0%, Uyghur: 26.0%, Han: 33.8%, p < 0.05, p < 0.05). Multivariate logistic regression analyses showed Gender (OR = 1.324), age (OR = 2.098, 3.681, 6.794, 9.473, 14.646), nationality (OR = 1.541), occupation (OR = 1.659, 1.576), education (OR = 1.260), BMI (OR = 1.842), WC (OR = 1.585), WHR (OR = 1.188), WHR (OR = 1.188), diabetes (OR = 1.879), hypertriglyceridemia (OR = 1.361), hypercholesterolemia (OR = 1.131) and high blood low density lipoprotein cholesterol (LDL-C) (OR = 1.956) were all positively correlated with hypertension, while low blood high density lipoprotein cholesterol (HDL-C) (OR = 0.765) was negatively correlated with hypertension.

    Resistant hypertension (RH) is defined as blood pressure (BP) that remains ⩾140 and/or 90 mm Hg despite therapy with ⩾3 full-dose antihypertensive drugs (classical definition=CD). A definition proposed subsequently (new definition=ND) includes patients requiring ⩾4 drugs irrespective of BP values. We aimed to evaluate whether both definitions characterize the same kind of patients.One hundred and twenty-four consecutively attended patients with RH were classified into two groups according to their BP control: 66 patients had non-controlled BP (all those who met the CD criteria plus a few patients who met the ND criteria); 58 patients had controlled BP (all with RH according to the ND). Clinical, laboratory and office BP data were recorded. RH patients with non-controlled BP were more frequently diabetic (72% vs 49%), and had higher plasmatic glucose (149 vs 130 mg dl(-1)), cholesterol (179 vs 164 mg dl(-1)), low-density lipoprotein (LDL)-cholesterol (107 vs 95 mg dl(-1)) and triglyceride (169 vs 137 mg dl(-1)) levels; P<0.05 for all comparisons. In multivariate logistic regression analysis, the variables that independently associated with non-controlled BP were diabetes (P=0.001) and higher LDL-cholesterol (P=0.007).We conclude that, although both cohorts of patients are phenotypically quite similar, uncontrolled RH patients have higher prevalence of diabetes mellitus and higher LDL-cholesterol levels than controlled RH patients.

    Hyperdynamic circulation in patients with liver cirrhosis is characterized by increased cardiac output and heart rate, and decreased systemic vascular resistance with low arterial blood pressure and currently focused on understanding the pathogenesis because of possibility of developing novel treatment modality. Basically, these hemodynamic alternations arise from portal hypertension. Portosystemic collaterals develop to counterbalance the increased intrahepatic vascular resistance to portal blood flow and induce an increase in venous return to heart. Increased shear stress in vascular endothelial cell related high blood flow by portosystemic shunting contributes to this upregulation of eNOS resulting in NO overproduction. Additionally, bypassing through portosystemic collaterals and escaping degradation of over-produced circulating vasodilators in the diseased liver can promote the peripheral arterial vasodilation. Vasodilation of the systemic and splanchnic circulations lead to a reduced systemic vascular resistance, and increased cardiac output and splanchnic blood flow. Furthermore, neurohumoral vasoconstrictive systems including systemic nervous system, rennin angiotensin aldosterone system, and vasopressin are intensively activated secondary to vasodilation. However, hyperdynamic circulation would be more aggravated by the activated vasoconstrictive systems. With the progression of the cirrhotic process, hyperdynamic alternations can be more profound due to hyporesponsiveness to vasoconstrictors and increased shunt formation in conjunction with autonomic neuropathy. Eventually, splanchnic arterial vasodilation results in an increase portal venous inflow, maintaining the elevated portal venous pressure. Hyperdynamic circulation is intimately involved in portal hypertension with liver cirrhosis, therefore it is reasonable to have an interest in complete understanding of the pathogenesis of hyperdynamic circulation to develop novel treatment modality.

    We describe the clinical features, therapies, and clinical course of pulmonary arterial hypertension (PAH) in a group of Filipinos with connective tissue diseases (CTDs). We retrospectively reviewed the records of patients diagnosed with PAH by a two-dimensional echocardiogram as a tricuspid regurgitant jet of more than 25 mmHg. All patients had underlying CTDs, defined by the American College of Rheumatology criteria, and were seen at the rheumatology clinics of the University of Santo Tomas Hospital and the St. Luke's Medical Center, Philippines. Of the 33 patients (32 women) included in the analysis, there were 14 patients with systemic lupus erythematosus (SLE), 12 with scleroderma, 5 with mixed connective tissue disease (MCTD), 1 with primary antiphospholipid syndrome (APS), and 1 with dermatomyositis. The average age at PAH diagnosis was 38 +/- 14 years (mean +/- SD), and the mean duration of illness from CTD to PAH diagnosis was 53 +/- 52 months. Twelve patients had died at the time of this report, with a median duration of 15 months (range 1-57 months) from PAH diagnosis to mortality: six of these had scleroderma, five with SLE, and one with APS. The following therapies were used in this group of patients: low molecular weight heparin, warfarin, calcium-channel blockers, aspirin, cyclophosphamide, bosentan, iloprost, and sildenafil. We have described the clinical profile of PAH in a group of Filipino patients with CTDs, most commonly SLE. Various forms of pharmacologic therapies were used among these patients. Mortality remains high, particularly among those with underlying scleroderma. Early recognition and treatment are crucial in order to provide a better outcome for these patients.

    This research aimed to analyze the clinical data of various etiologies of hypertension in patients hospitalized in the Endocrinology Division. The differences between essential and secondary hypertension were examined to provide a basis for clinical differential diagnosis. The data from all the inpatients with hypertension of unknown origin admitted in the Endocrinology Division of the First Affiliated Hospital of the Zhejiang University School of Medicine from January 2001 to May 2011 were reviewed. The patients were classified into either essential or secondary hypertensive groups. The differentiating parameters of these forms of hypertension were analyzed using the one-factor and multi-factor logistic regression analysis. A total of 1,001 cases were selected in which 346 cases (34.6%) were essential hypertensive and 655 cases (65.4%) were secondary hypertensive. Adrenal hypertension was the primary cause of secondary hypertension, followed by renal artery, central, psychogenic, and renal hypertension as well as others that have not been classified systematically. Using one-factor analysis, significant differences were found among duration of hypertension, age, the onset age, family history of hypertension, diastolic pressure on admission, Cushing syndrome, body mass index (BMI), urine protein, serum creatinine, orthostatic aldosterone, ratio of orthostatic aldosterone to renin activity, incidence of fatty liver displayed by type-B ultrasound, and computed tomography adrenal masses incidence (P < 0.05). Multi-factor regression analysis showed that family history of hypertension (OR = 7.196) and BMI above the normal range (OR = 15.124) were the independent factors that predicted essential hypertension, but failed to determine any other valid predictors of secondary causes except adrenal masses (OR = 10.114), orthostatic aldosterone value >200 pg/ml (OR = 9.742), and a ratio of orthostatic aldosterone and renin activity >40 (OR = 4.723).

    Hypertension is a common disease and a crucial predisposing factor of cardiovascular diseases. Approximately 10% of hypertensive patients are secondary hypertension, a pathogenetic factor of which can be identified. Secondary hypertension consists of endocrine, renal, and other diseases. Primary aldosteronism, Cushing's syndrome, pheochromocytoma, hyperthyroidism, and hypothyroidism result in endocrine hypertension. Renal parenchymal hypertension and renovascular hypertension result in renal hypertension. Other diseases such as obstructive sleep apnea syndrome are also very prevalent in secondary hypertension. It is very crucial to find and treat secondary hypertension at earlier stages since most secondary hypertension is curable or can be dramatically improved by specific treatment. One should keep in mind that screening of secondary hypertension should be done at least once in a daily clinical practice. PMID:26619670

    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.

    Background Resistant hypertension is associated with adverse clinical outcome in hypertensive patients. However, the prognostic significance of resistant hypertension in patients with heart failure remains uncertain. Methods and Results The 1 year survival and heart failure re-hospitalization rate of 1288 consecutive patients admitted to a university hospital for either newly diagnosed heart failure or an exacerbation of prior chronic heart failure was analyzed. Resistant hypertension was defined as uncontrolled blood pressure (>140/90 mmHg) despite being compliant with an antihypertensive regimen that includes 3 or more drugs (including a diuretic). A total of 176 (13.7%) heart failure patients had resistant hypertension. There was no difference in all cause mortality, cardiovascular mortality, and heart failure related re-hospitalization between patients with versus without resistant hypertension. Diabetes [hazard ratio = 1.62, 95% confidence interval = 1.13–2.34; P = 0.010] and serum sodium >139 mmol/L (hazard ratio = 1.54, 95% confidence interval = 1.06–2.23; P = 0.024) were independently associated with resistant hypertension. Patients with resistant hypertension had a relatively higher survival rate (86.9% vs. 83.8%), although the difference was not significant (log-rank x2 = 1.00, P = 0.317). In patients with reduced ejection fraction, heart failure related re-hospitalization was significantly lower in patients with resistant hypertension (45.8% vs. 59.1%, P = 0.050). Conclusions Resistant hypertension appears to be not associated with adverse clinical outcome in patients with heart failure, in fact may be a protective factor for reduced heart failure related re-hospitalization in patients with reduced ejection fraction.

    There are increasing researches about non-communicable disease such as elevated blood pressure among people living with HIV before and after initiation of highly active antiretroviral therapy (HAART). This cross-sectional study was designed to determine the prevalence of hypertension and associated risk factors among 340 HIV-infected patients on antiretroviral therapy at a Malaysian public hospital providing HIV-related treatment. Data on socioeconomic background, anthropometry, medical history and dietary intake of the patients were collected. Hypertension is defined as blood pressure ≥130/85 (mm Hg). Prevalence of hypertension was 45.60% (n=155) of which 86.5% of the hypertensive group were male (n=134). The results showed that increase in age (OR 1.051, 95% confidence interval (CI) 1.024-1.078), higher body mass index (OR 1.18, 95% CI 1.106-2.71), bigger waist circumference (OR 1.18, 95%CI 1.106-2.71), higher waist-hip ratio (OR 1.070, 95%CI 1.034-1.106), higher fasting plasma glucose (OR 1.332, 95% CI 0.845-2.100) and percentage energy intake from protein >15 (OR 2.519, 95%CI 1.391-4.561) were significant risk factors for hypertension (p<0.001). After adjusting for other variables, increasing age (adjusted odds ratio (aOR) 1.069 95%CI 1.016-1.124, p=0.010), being male (aOR 3.026, 95%CI 1.175-7.794, p=0.022) and higher body mass index (aOR 1.26, 95%CI 1.032-1.551, p=0.024) were independently associated with hypertension. None of the antiretroviral therapy and immunologic factors was linked to hypertension. In conclusion hypertension among PLHIV was linked to the well-known risk factors such as age, gender and body mass index. With HAART, people can live longer by making monitoring and control of some reversible factors, especially excessive weight gain for maintaining quality of life. PMID:24576366

    Exercise training has different effects on arterial stiffness according to training modalities. The optimal exercise modality for improvement of arterial function in normotensive and hypertensive individuals has not been well established. In this review, we aim to evaluate the effects of aerobic, resistance and combined aerobic and resistance training on arterial stiffness in individuals with and without hypertension. We systematically searched the Pubmed and Web of Science database from 1985 until December 2013 for relevant randomised controlled trials (RCTs). The data were extracted by one investigator and checked by a second investigator. The training effects on arterial stiffness were estimated using weighted mean differences of the relative changes (%) with 95% confidence intervals (CIs). We finally reviewed the results from 17 RCTs. The available evidence indicates that aerobic exercise tends to have a beneficial effect on arterial stiffness in normotensive and hypertensive patients, but does not affect arterial stiffness in patients with isolated systolic hypertension. Resistance exercise has differing effects on arterial stiffness depending on type and intensity. Vigorous resistance training is associated with an increase in arterial stiffness. There seem to be no unfavourable effects on arterial stiffness if the training is of low intensity, in a slow eccentric manner or with lower limb in healthy individuals. Combined training has neutral or even a beneficial effect on arterial stiffness. In conclusion, our review shows that exercise training has varying effects on arterial stiffness depending on the exercise modalities.

    Pulmonary Hypertension (PH) is a complex disorder characterized by elevated pressures in the pulmonary artery that cause right heart failure and eventually leads to death. Treatment regimens can be complex and mortality is high. The purpose of this study was to determine how people with PH are using an online Discussion Board. Qualitative descriptive methodology was used to analyze a convenience sample of self-identified patients with PH. Internet posts to an online Discussion Board from January 1, 2010 to December 31, 2010 were analyzed for common themes. Five hundred forty-nine individuals with PH posted to the Discussion Board. Four themes emerged: Uncertainty and Concern, Guidance and Validation, Support, and Refocusing Life. People with PH are using the Internet to answer questions about PH and seeking support. Future research needs to be conducted to further explore the needs and concerns of people with PH to provide tailored interventions.

    This Cochrane review had the objectives to determine the dose-related decrease in blood pressure due to thiazide diuretics compared with placebo control in the treatment of hypertensive patients. Hydrochlorothiazide has a dose-related blood pressure-lowering effect over the dose range 6.25, 12.5, 25 and 50 mg/day of 4/2, 6/3, 8/3 and 11/5 mmHg, respectively. This exceeds the mean 3 mmHg reduction achieved by angiotensin-converting-enzyme inhibitors and angiotensin receptor blockers as shown in other Cochrane reviews, which have compared these antihypertensive drugs with placebo having used similar inclusion/exclusion criteria.

    Fetal exposure to parental smoking may lead to developmental adaptations and promote various diseases in later life. This study evaluated the associations of parental smoking during pregnancy with the risk of hypertension in the daughter in adulthood, and assessed whether these associations are explained by birth weight or body weight throughout life. We used data on 33086 participants of the Nurses' Health Study II and the Nurses' Mothers' Cohort. Cox proportional hazards models were used to examine the associations of maternal and paternal smoking during pregnancy with the nurse daughter, with self-reported physician-diagnosed hypertension from 1989 until 2007. Overall, 8575 (25.9%) mothers and 18874 (57.0%) fathers smoked during pregnancy. During follow-up, 7825 incident cases of adult-onset hypertension were reported. Both maternal and paternal smoking of ≥ 15 cigarettes/d during pregnancy were associated with increased risks of hypertension (rate ratio, 1.19; 95% CI, 1.09-1.29; and rate ratio, 1.18; 95% CI, 1.12-1.25, respectively) in the age-adjusted models. Further adjustment for birth weight did not affect the effect estimates appreciably, whereas additional adjustment for body shape and weight until age 18, or current body mass index, attenuated the associations with both maternal and paternal smoking (rate ratio, 1.07; 95% CI, 0.98-1.16; and rate ratio, 1.06; 95% CI, 1.01-1.12, respectively). The associations of parental smoking during pregnancy with the risk of hypertension in the offspring were largely explained by body weight throughout life, suggesting that these associations may not reflect direct intrauterine mechanisms.

    Pulmonary hypertension (PH) is a known risk factor for perioperative complications. Unlike in the case of cardiac surgery, PH is currently not listed as an independent risk factor for postoperative complications in guidelines for the management of noncardiac surgery. Despite the paucity of data, though, patients with PH are often counseled against having elective procedures because early and sudden postoperative deaths have been reported. Patients with PH are unable to accommodate alterations in right ventricular (RV) preload or afterload induced by fluid shifts, medications, or changes in the autonomic nervous system precipitated by hypoxia or hypercapnia. These factors become magnified in situations of added stress such as surgical intervention. Systemic hypotension and arrhythmias may precipitate RV ischemia, further worsening RV function. Patient and surgical characteristics and choice of anesthetic technique are crucial factors in perioperative management. The two main principles of perioperative management are the prevention of systemic hypotension (risk of RV ischemia) and the prevention of acute elevations in pulmonary arterial pressure (risk of RV failure). Close monitoring, optimization of systemic BP, pain control, oxygenation and ventilation, avoidance of exacerbating factors, and use of vasopressors and pulmonary vasodilators as necessary are essential elements of management. Understanding the pathophysiology, cause, and severity of PH in the individual perioperative patient allows accurate risk assessment, optimization of PH and RV function prior to surgery, and appropriate intraoperative and postoperative management.

    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

    Haemodynamic tests were performed at rest and during exercise in 41 patients with arterial hypertension and early impairment of left-ventricular function, before and after administration of a single dose of 0.6 mg beta-methyl-digoxin. After clinical, ECG and coronary-angiographic studies, the patients were assigned to two groups. Group I: 17 patients with transmural infarcts in the chronic stage or with angina. Cardiac output was within normal limits at rest and on exercise and was not significantly altered by administration of beta-methyl-digoxin. There was no significant fall during exercise of the abnormally elevated pulmonary "wedge" pressure or of other pressures in the lesser circulation after digitalis. Group II: 24 patients without signs of coronary heart disease. They, too, had a normal cardiac output at rest and on exercise, not significantly changed by digitalisation with beta-methyl-digoxin. But pulmonary "wedge" pressure and right-atrial mean pressure were significantly reduced during exercise. Before beta-methyl-digoxin the mean "wedge" pressure rose on exercise to an average of 27.3 +/- 5.4 mm Hg, but after beta-methyl-digoxin to only 21.7 +/- 5.1 mm Hg (P less than 0.001). The mean right atrial pressure changed similar. These results indicate that acute digitalisation at the stated dosage in general has an effect on abnormal myocardial function only if there is no additional coronary heart disease. PMID:880903

    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.

    Hypertension and excess body weight are major risk factors of cardiovascular morbidity and mortality in developing countries. In countries with a high HIV prevalence, it is unknown how increased antiretroviral treatment and care (ART) coverage has affected the prevalence of overweight, obesity, and hypertension. We conducted a health survey in 2010 based on the WHO STEPwise approach in 14,198 adult resident participants of a demographic surveillance area in rural South Africa to investigate factors associated with hypertension and excess weight including HIV infection and ART status. Women had a significantly higher median body mass index (BMI) than men (26.4 vs. 21.2 kg/m(2), p<0.001). The prevalence of obesity (BMI ≥ 30 kg/m(2)) in women (31.3%, 95% confidence interval (CI) 30.2-32.4) was 6.5 times higher than in men (4.9%, 95% CI 4.1-5.7), whereas prevalence of hypertension (systolic or diastolic blood pressure ≥ 140 or 90 mm Hg, respectively) was 1.4 times higher in women than in men (28.5% vs 20.8%, p<0.001). In multivariable regression analysis, both hypertension and obesity were significantly associated with sex, age, HIV and ART status. The BMI of women and men on ART was on average 3.8 (95% CI 3.2-3.8) and 1.7 (95% CI 0.9-2.5) kg/m(2) lower than of HIV-negative women and men, respectively. The BMI of HIV-infected women and men not on ART was on average 1.2 (95% CI 0.8-1.6) and 0.4 (95% CI -0.1-0.9) kg/m(2) lower than of HIV-negative women and men, respectively. Obesity was a bigger risk factor for hypertension in men (adjusted odds ratio (aOR) 2.99, 95% CI 2.00-4.48) than in women (aOR 1.64, 95% CI 1.39-1.92) and overweight (25 ≤ BMI<30) was a significant risk factor for men only (aOR 1.53 95% CI 1.14-2.06). Our study suggests that, cardiovascular risk factors of hypertension and obesity differ substantially between women and men in rural South Africa.

    Obesity, metabolic syndrome, dyslipidemia, and poor quality of life are common conditions associated with hypertension, and incidence of hypertension is age dependent. However, an effective program to prevent hypertension and to improve biomedical factors and quality of life has not been adequately examined or evaluated in Chinese older adults. This study aims to examine the effectiveness of a Tai Chi program to improve health status in participants with hypertension and its related risk factors such as dyslipidemia, hyperglycemia, and quality of life in older adults in China. A randomized study design was used. At the conclusion of the intervention, 266 patients remained in the study. Blood pressure and biomedical factors were measured according to the World Diabetes Association standard 2002. A standardized quality-of-life measure was used to measure health-related quality of life. It was found that a Tai Chi program to improve hypertension in older adults is effective in reducing blood pressure and body mass index, maintaining normal renal function, and improving physical health of health-related quality of life. It did not improve existing metabolic syndrome levels, lipid level (dyslipidemia) or fasting glucose level (hyperglycemia), to prevent further deterioration of the biomedical risk factors. In conclusion, Tai Chi is effective in managing a number of risk factors associated with hypertension in Chinese older adults. Future research should examine a combination of Tai Chi and nutritional intervention to further reduce the level of biomedical risks. PMID:26251005

    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.

    Hypertension is highly prevalent affecting nearly one third of the US adult population. Though generally approached as an outpatient disorder, elevated blood pressure is observed in a majority of hospitalized patients. The spectrum of hypertensive disease ranges from patients with hypertensive emergency including markedly elevated blood pressure and associated end-organ damage to asymptomatic patients with minimally elevated pressures of unclear significance. It is important to note that current evidence-based hypertension guidelines do not specifically address inpatient hypertension. This narrative review focuses primarily on best practices for diagnosing and managing nonemergent hypertension in the inpatient setting. We describe examples of common hypertensive syndromes, provide suggestions for optimal post-acute management, and point to evidence-based or consensus guidelines where available. In addition, we describe a practical approach to managing asymptomatic elevated blood pressure observed in the inpatient setting. Finally, arranging effective care transitions to ensure optimal ongoing hypertension management is appropriate in all cases. PMID:26362300

    Previous studies have demonstrated that perinatal nicotine exposure increased blood pressure (BP) in adult offspring. However, the underlying mechanisms were unclear. The present study tested the hypothesis that perinatal nicotine-induced programming of hypertensive response is mediated by enhanced reactive oxygen species (ROS) in the vasculature. Nicotine was administered to pregnant rats via subcutaneous osmotic mini-pumps from Day 4 of gestation to Day 10 after birth, in the absence or presence of the ROS inhibitor N-acetyl-cysteine (NAC) in the drinking water. Experiments were conducted in 8-mo-old male offspring. Perinatal nicotine treatment resulted in a significant increase in arterial ROS production in offspring, which was abrogated by NAC. Angiotensin II (Ang II)-induced BP responses were significantly higher in nicotine-treated group than in saline-treated control group, and NAC treatment blocked the nicotine-induced increase in BP response. Consistent with that, the nicotine treatment significantly increased both Ang II-induced and phorbol [12, 13]-dibutyrate (PDBu, a Prkc activator)-induced arterial contractions in adult offspring, which were blocked by NAC treatment. In addition, perinatal nicotine treatment significantly attenuated acetylcholine-induced arterial relaxation in offspring, which was also inhibited by NAC treatment. Results demonstrate that inhibition of ROS blocks the nicotine-induced increase in arterial reactivity and BP response to vasoconstrictors in adult offspring, suggesting a key role for increased oxidative stress in nicotine-induced developmental programming of hypertensive phenotype in male offspring.

  4. Clinical Implications of Hemoptysis in Patients with Pulmonary Arterial Hypertension

    Introduction Pulmonary arterial hypertension (PAH) is a disabling disease that may result in haemoptysis. Patients with congenital heart disease associated PAH (CHD-APAH) may have a survival advantage when compared with patients with other types of PAH presenting with haemoptysis. The effects of aetiology and sub-sequent management choice of haemoptysis in PAH patients is not well-defined. Methods We conducted outcome analysis in CHD-APAH vs. all other subtypes of PAH patients presenting with haemoptysis to The Methodist Hospital. Twenty-one patients were identified, thirteen patients in the CHD-APAH group and eight patients in the non-CHD group. We evaluated outcomes related to treatment (bronchial artery embolization vs. conservative management), hospital length of stay, mortality rates and survival in this cohort. Results The CHD-APAH and non-CHD groups had similar baseline demographic, haemodynamic and laboratory values except BMI was higher in the non-CHD group and haematocrit was higher in the CHD-APAH group. Twenty-eight-day mortality (0% vs. 31%) and 1-year mortality (0% vs. 54%) was lower in the CHD-APAH patients as compared with non-CHD group. A statistically significant difference was found in the survival rate in favour of CHD-APAH group for the total follow-up period (p = 0.02). Although not statistically significant, patients treated with BAE had shorter length of stay (4.0 days ± 4.0 vs. 13.7 days ± 22.5; p = 0.26). There was recurrent haemoptysis in 43% of patients treated with BAE. Conclusion Haemoptysis in PAH patients is a serious event with a high mortality rate. CHD-APAH seems to confer a survival advantage, independent of therapy utilised. Termination of haemoptysis with BAE is rapid with relatively few complications except for frequent re-bleeding episodes. Further studies are needed to determine the risk factors that may predispose PAH patients to excessive mortality from haemoptysis and to identify an optimal therapeutic modality. PMID

    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.

  6. Comparative effects of non-steroidal anti-inflammatory drugs (NSAIDs) on blood pressure in patients with hypertension

    2012-01-01

    Background Nonsteroidal anti-inflammatory drugs (NSAIDs) may disrupt control of blood pressure in hypertensive patients and increase their risk of morbidity, mortality, and the costs of care. The objective of this study was to examine the association between incident use of NSAIDs and blood pressure in patients with hypertension. Methods We conducted a retrospective cohort study of adult hypertensive patients to determine the effects of their first prescription for NSAID on systolic blood pressure and antihypertensive drug intensification. Data were collected from an electronic medical record serving an academic general medicine practice in Indianapolis, Indiana, USA. Using propensity scores to minimize bias, we matched a cohort of 1,340 users of NSAIDs with 1,340 users of acetaminophen. Propensity score models included covariates likely to affect blood pressure or the use of NSAIDs. The study outcomes were the mean systolic blood pressure measurement after starting NSAIDs and changes in antihypertensive therapy. Results Compared to patients using acetaminophen, NSAID users had a 2 mmHg increase in systolic blood pressure (95% CI, 0.7 to 3.3). Ibuprofen was associated with a 3 mmHg increase in systolic blood pressure compared to naproxen (95% CI, 0.5 to 4.6), and a 5 mmHg increase compared to celecoxib (95% CI, 0.4 to 10). The systolic blood pressure increase was 3 mmHg in a subgroup of patients concomitantly prescribed angiotensin converting enzyme inhibitors or calcium channel blockers and 6 mmHg among those prescribed a beta-adrenergic blocker. Blood pressure changes in patients prescribed diuretics or multiple antihypertensives were not statistically significant. Conclusion Compared to acetaminophen, incident use of NSAIDs, particularly ibuprofen, is associated with a small increase in systolic blood pressure in hypertensive patients. Effects in patients prescribed diuretics or multiple antihypertensives are negligible. PMID:23092442

    Acupuncture was used in a combination treatment of 110 patients with stage I to III hypertensive disease (HD). As far as acupuncture points are concerned we followed the lines laid down in the traditional Chinese medicine (TCM), with results of Ryodoraku investigation and those of auriculodiagnosis supplying a guide to the choice of points taking into account the type of hemodynamics. In our experience, redundancy with the meridian of the liver, unlike TCM notions about dominance under HD syndrome of fire and wind in the liver, was found to be the case in 40 percent of the patients while redundancy with meridians of the heart and pericardium was recordable in 97 and 84 percent of the cases respectively. The use of acupuncture points in the neck collar region and head and of antique points along the meridians of the heart and liver were shown to be effective treatment having a beneficial effect on cerebral circulation. Results of the clinical study suggest efficiency, expediency, and pathogenic value of acupuncture in the treatment of HD patients. PMID:10878993

    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.

    Abernethy malformation is a rare abnormal embryological development of splanchnic venous system characterised by the presence of a congenital extrahepatic portosystemic shunt. We present a rare case of an adult male patient that was admitted with severe lower gastrointestinal bleeding, requiring multiple blood transfusions. The patient's medical history and the laboratory tests performed led to the misdiagnosis of a congenital Abernethy malformation. We present a rare case, discussing the reasons for the misdiagnosis and we conclude that management of clinical data and imaging are highly important to discard these types of congenital malformations that can mimic a portal hypertension condition.

    This study assessed the risk of new-onset gout following prescribing of hydrochlorothiazide (HCTZ) compared with chlorthalidone (CTD). This retrospective cohort analysis used administrative claims from 2000 to 2012 to identify patients aged 18 to 89 years with hypertension who were prescribed CTD or HCTZ. Patients were excluded if they had a prior diagnosis of gout, conditions or prescription claims for medications that alter risk of gout, or if they switched between these two diuretics. A total of 1011 patients prescribed CTD were matched with 2022 patients prescribed HCTZ based on age, sex, and Chronic Condition Indicator. New-onset gout occurred in 17 of 1011 (1.68%) patients in the CTD group and in 26 of 2022 (1.29%) patients in the HCTZ group (P=.27). The number of days to first occurrence of gout was 183.6 days and 152.7 days in the CTD and HCTZ groups, respectively (P=.39). The mean daily dose was 22.7 mg for CTD and 24.3 mg for HCTZ, and the median dose of both CTD and HCTZ was 25 mg at the time of new-onset gout. Patients prescribed CTD for hypertension have a similar risk of developing new-onset gout compared with patients prescribed similar doses of HCTZ.

  14. Epidemiology, diagnosis and management of hypertension among patients on chronic dialysis.

    The diagnosis and management of hypertension among patients on chronic dialysis is challenging. Routine peridialytic blood pressure recordings are unable to accurately diagnose hypertension and stratify cardiovascular risk. By contrast, blood pressure recordings taken outside the dialysis setting exhibit clear prognostic associations with survival and might facilitate the diagnosis and long-term management of hypertension. Once accurately diagnosed, management of hypertension in individuals on chronic dialysis should initially involve non-pharmacological strategies to control volume overload. Accordingly, first-line strategies should focus on achieving dry weight, individualizing dialysate sodium concentrations and ensuring dialysis sessions are at least 4 h in duration. If blood pressure remains unresponsive to volume management strategies, pharmacological treatment is required. The choice of appropriate antihypertensive regimen should be individualized taking into account the efficacy, safety, and pharmacokinetic properties of the antihypertensive medications as well as any comorbid conditions and the overall risk profile of the patient. In contrast to their effects in the general hypertensive population, emerging evidence suggests that β-blockers might offer the greatest cardioprotection in hypertensive patients on dialysis. In this Review, we discuss estimates of the epidemiology of hypertension in the dialysis population as well as the challenges in diagnosing and managing hypertension among these patients.

    Background We investigated the prevalence, awareness, treatment, and control rate of hypertension in Korean adults with diabetes using nationally representative data. Methods Using data of 5,105 adults from the fifth Korea National Health and Nutrition Examination Survey in 2011 (4,389 nondiabetes mellitus [non-DM]), 242 newly diagnosed with DM (new-DM), and 474 previously diagnosed with DM (known-DM), we analyzed the prevalence of hypertension (mean systolic blood pressure ≥140 mm Hg, diastolic blood pressure ≥90 mm Hg, or use of antihypertensive medication) and control rate of hypertension (blood pressure [BP] <130/80 mm Hg). Results The prevalence of hypertension in diabetic adults was 54.6% (44.4% in new-DM and 62.6% in known-DM, P<0.0001 and P<0.0001, respectively) compared with non-DM adults (26.2%). Compared to non-DM, awareness (85.7%, P<0.001) and treatment (97.0%, P=0.020) rates were higher in known-DM, whereas no differences were found between new-DM and non-DM. Control rate among all hypertensive subjects was lower in new-DM (14.9%), compared to non-DM (35.1%, P<0.001) and known-DM (33.3%, P=0.004). Control rate among treated subjects was also lower in new-DM (25.2%), compared to non-DM (68.4%, P<0.0001) and known-DM (39.9%, P<0.0001). Conclusion Higher prevalence and low control rate of hypertension in adults with diabetes suggest that stringent efforts are needed to control BP in patients with diabetes, particularly in newly diagnosed diabetic patients.

    Type 2 diabetes mellitus and hypertension are independent risk factors for atherosclerotic lesions that are partly linked with dyslipidaemia. This risk is additive when diabetes and hypertension occur concurrently. In order to determine if concurrent type 2 diabetes and hypertension results in putative increases in dyslipidaemia in a Nigerian population, we compared the plasma lipid levels, atherogenic index and prevalence of dyslipidaemia among age and sex-matched indigenous Nigerians with type 2 diabetes, hypertension and concurrent diabetes and hypertension. Age and sex-matched healthy Nigerians that are free of diabetes and hypertension served as controls. The patients as a whole were more likely to have dyslipidaemia than controls (p < 0.05). High-density lipoprotein cholesterol was similar among patients and controls. Mean total cholesterol, high-density lipoprotein cholesterol; low-density lipoprotein cholesterol and triglyceride levels, atherogenic index and prevalence of dyslipidaemia did not differ significantly among patients with hypertension, diabetes, and concurrent hypertension and diabetes (p = 0.99 for each parameter). It is concluded that concurrent hypertension and type 2 diabetes does not result in a more severe dyslipidaemia than when either of the two conditions occurs in isolation. We attribute this to the common pathogenic link between hypertension, diabetes and dyslipidaemia in metabolic syndrome. Evidence, albeit indirect, of this syndrome among native Africans is, therefore, provided. PMID:12793789

    The prevalence of hypertension is higher among blacks than whites. However, inconsistent findings have been reported on the incidence of hypertension among middle-aged and older blacks and whites, and limited data are available on the incidence of hypertension among Hispanics and Asians in the United States. Therefore, this study investigated the age-specific incidence of hypertension by ethnicity for 3146 participants from the Multi-Ethnic Study of Atherosclerosis. Participants, age 45 to 84 years at baseline, were followed for a median of 4.8 years for incident hypertension, defined as systolic blood pressure ≥140 mm Hg, diastolic blood pressure ≥90 mm Hg, or the initiation of antihypertensive medications. The crude incidence rate of hypertension, per 1000 person-years, was 56.8 for whites, 84.9 for blacks, 65.7 for Hispanics, and 52.2 for Chinese. After adjustment for age, sex, and study site, the incidence rate ratio (IRR) for hypertension was increased for blacks age 45 to 54 (IRR: 2.05 [95%CI: 1.47 to 2.85]), 55 to 64 (IRR: 1.63 [95% CI: 1.20 to 2.23]), and 65 to 74 years (IRR: 1.67 [95% CI: 1.21 to 2.30]) compared with whites but not for those 75 to 84 years of age (IRR: 0.97 [95% CI: 0.56 to 1.66]). Additional adjustment for health characteristics attenuated these associations. Hispanic participants also had a higher incidence of hypertension compared with whites; however, hypertension incidence did not differ for Chinese and white participants. In summary, hypertension incidence was higher for blacks compared with whites between 45 and 74 years of age but not after age 75 years. Public health prevention programs tailored to middle-aged and older adults are needed to eliminate ethnic disparities in incident hypertension.

    The onset of supraventricular arrhythmias (SVA) may be associated with clinical worsening in patients with pulmonary arterial hypertension (PAH). However, limited data have been reported, especially at long-term follow-up. Aim of this study was to investigate the incidence of SVA in our patients with PAH, the risk factors correlated to their onset and the prognostic impact. All consecutive patients with PAH without history of SVA were enrolled. Incidence of new SVA was investigated and also the risk factors for SVA. Primary end point of the study was the impact of SVA on a composite of all-cause mortality and re-hospitalization, whereas mortality was the secondary end point. Seventy-seven patients were enrolled. No significant differences in the clinical or instrumental baseline characteristics between the 2 study groups were reported. During a median follow-up of 35 months (interquartile range 21.5 to 53.5), 17 (22%) patients experienced SVA. Development of SVA was associated with worsening of prognostic parameters at the follow-up: increasing of World Health Organization (WHO) functional class (p = 0.005) and N-terminal-pro-brain natriuretic peptide (NT-proBNP) (p = 0.018) and reduction of 6-minute walking distance (p = 0.048), tricuspid annular plane systolic excursion (TAPSE) (p = 0.041), and diffusing capacity of the lung for carbon monoxide (p = 0.025). The primary end point occurred in 13 patients (76%) in the SVA group and in 22 patients (37%) in the group without SVA (p = 0.004), whereas 9 patients (53%) among those with SVA died during the follow-up compared with 8 (13%) among those without (p = 0.001). At multivariate analysis, development of SVA was independently associated with an increased risk to meet the both primary (hazard ratio 2.13; 95% confidence interval 1.07 to 4.34; p = 0.031) and secondary (hazard ratio 4.1; 95% confidence interval 1.6 to 10.6; p = 0.004) end points.

    Objective. To evaluate the impact of the Salt Education Program for hypertensive adults on student pharmacists' knowledge, behaviors, and attitudes regarding sodium consumption. Design. As part of the introductory pharmacy practice experience program in community pharmacies, student pharmacists assessed patients' sodium intake knowledge and behaviors, taught them how to read nutrition labels, and obtained information about their hypertensive conditions. Students completed pre-and post-intervention questionnaires in April and August 2012, respectively. Assessment. One hundred thirty student pharmacists (70% female, 78% white) completed pre- and post-intervention questionnaires. Students demonstrated significant improvements in knowledge scores (p<0.001) and perceived benefit of a low-salt diet (p=0.004). Further, there were significant improvements in the self-reported frequency of looking at sodium content of foods when shopping (p<0.001) and purchasing low-salt foods (p=0.004). Conclusion. Changes in students' knowledge, behaviors, and attitudes after participating in the Salt Education program suggested that the program was effective in improving student knowledge, behaviors, and attitudes.

    We studied the echographic LVH indexes early detected in recent AHT. We analyzed the LVH regression after 12 months of treatment with Captopril. We describe the modifications observed in the lipidic metabolism. We studied 25 patients with an average age of 40 years and maximum essential arterial hypertension with 15 months of evolution. Septal thickness showed a reduction in systole and diastole at 6 months (p < 0.01). The posterior wall thickness decreased 3 mm in systole and diastole at 12 months (p < 0.001). Afterload diastolic diameter improved at 6 months. LV mass decreased from 321 gr to 279 gr at 6 months and to 268 at 12 months (p < 0.001); the same reduction was observed in mass index. At six months, total cholesterol and LDL had decreased (p < 0.05) and HDL-cholesterol had increased, although without statistical significance. Triglycerides showed a significant decrease at 12 months (p < 0.001). Seventy per cent of the patients were controlled with Captropil 100 mg/day and the remainder, with 50 mg.

    The presence of pulmonary arterial hypertension (PAH) increases morbidity and reduces survival in patients with congenital heart disease (CHD). PAH-CHD is a heterogeneous condition, depending on the type of the underlying defect and previous repair strategies. There is growing evidence of the benefits of PAH-specific therapy in the PAH-CHD population, but despite recent advances mortality rates remain relatively high. In the last years, an increasing focus has been placed on patients with PAH-CHD and net left-to-right shunt. Currently, there are limited data to guide the management of these patients and uncertainty on the cut-off values for eventual defect closure. Pregnancy conveys significant risks in PAH-CHD patients: appropriate counselling and care, including psychological support and a multidisciplinary team, should be part of the routine management of women with PAH-CHD of reproductive age. Some subgroups, such as patients with Down's syndrome, Fontan circulation and 'segmental' pulmonary hypertension, present particular challenges in terms of management and therapy. The current review focuses on contemporary treatment strategies in PAH-CHD patients with particular emphasis on challenging patient groups and conditions.

    Secondary hypertension affects only 5-10 % of hypertensive patients. Screening is expensive and time-consuming and should be performed only in patients for whom there is a high clinical suspicion of secondary hypertension. Clinical signs of secondary forms of hypertension are new-onset hypertension in patients without other risk factors (i.e., family history, obesity, etc.), sudden increase of blood pressure (BP) in a previously stable patient, increased BP in prepubertal children, resistant hypertension, and severe hypertension or hypertensive emergencies. In adults, renal parenchymal and vascular diseases as well as obstructive sleep apnea are the most common causes of secondary hypertension. Medication-induced hypertension and non-adherence to medication have to be ruled out. Of the endocrine causes associated with hypertension, primary aldosteronism is the most common. Other endocrine causes of hypertension such as thyroid disease (hypo- or hyperthyroidism), hypercortisolism (Cushing's syndrome), hyperparathyroidism, and pheochromocytoma are rare. Monogenetic forms of hypertension are mostly of tubular origin and associated with alterations in mineralocorticoid handling or signaling. Rare causes of hypertension also include inflammatory vascular disease. Acute forms of vasculitis may present as "malignant" hypertension with associated thrombotic microangiopathy and organ damage/failure. It is important to diagnose these rare forms of hypertension in order to prevent acute organ damage in these patients or unnecessary invasive treatment strategies. PMID:25700646

    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.

    We determine the prevalence and determinants of clustering of hypertension, abnormal glucose tolerance, hypercholesterolaemia and overweight in Malaysia. A national probability sample of 17,392 individuals aged 30 years or older had usable data. 61% of adults had at least one risk factor, 27% had 2 or more risk factors. The observed frequency of 4 factors cluster was 6 times greater than that expected by chance. Indian and Malay women were at particular high risk of risk factors clustering. Individuals with a risk factor had 1.5 to 3 times higher prevalence of other risk factors. Ordinal regression analyses show that higher income, urban residence and physical inactivity were independently associated with risk factors clustering, lending support to the hypotheses that risk factors clustering is related to lifestyle changes brought about by modernisation and urbanisation. In conclusion, risk factor clustering is highly prevalent among Malaysian adults. Treatment and prevention programme must emphasise the multiple risk factor approach.

    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

    We sought to investigate the characteristics, survival and risk factors for mortality in Chinese patients with connective tissue disease (CTD)-associated pulmonary arterial hypertension (APAH) in modern therapy era. 129 consecutive adult patients who visited one of three referral centres in China with a diagnosis of CTD-APAH confirmed by right heart catheterisation during the previous 5 years were enrolled. The end-point was all-cause death or data censoring. Systemic lupus erythematosus was the most common underlying CTD (49%) and systemic sclerosis just accounted for 6% in this cohort. The overall survival at 1 and 3 years was 92% and 80%, respectively. Pericardial effusion, a shorter 6-min walk distance, lower mixed venous oxygen saturation, higher pulmonary vascular resistance (PVR) and alkaline phosphatase (ALP), and lower total cholesterol levels were all associated with a higher risk of death among the study population. Higher PVR and ALP were independent predictors of mortality. In conclusion, unlike in western patients, systemic lupus erythematosus is the most common underlying disease in Chinese patients with CTD-APAH. The survival of Chinese patients with CTD-APAH in the modern treatment era is similar to that in western countries. Elevated PVR and ALP are independent risk factors for poor outcomes.

Adult patients of both sex, who were attending medicine OPD of Shri Krishna Hospital, Karamsad, Gujarat since last 6 months and being prescribed antihypertensive drug/s for hypertension, were selected for the study. Hypertensive patients with co-morbities diabetes mellitus, ischemic heart diseases, congestive heart failure, and chronic renal diseases were included in the study. Adherence to JNC-VII guideline and WHO-ISH guidelines with respect to prescribing antihypertensive drugs in patients with diabetes mellitus were found to be 97% and 40.81% respectively, while it was found to be 72.27% to both the guidelines in patients with IHD. Similarly in cases of hypertension with CHF, adherence to prescribing antihypertensive were found to be 93.62% and 38.30% respectively, whereas for CKD patients, adherence to both guidelines was found to be same i.e. 33.33%. There is need of following such authentic guidelines in managing hypertension like chronic disease since these guidelines are based on various clinical trials and successful attainment of target BP in patients will be much easier by implementing them.

    Use of ambulatory blood pressure (BP) monitoring (ABPM) allows for identification of dipping, nondipping, extreme dipping, and reverse dipping of BP. Using office BP and ABPM, hypertension subtypes can be identified: sustained normotension (SNT), white-coat hypertension, masked hypertension, and sustained hypertension. The comparison of hemodynamic parameters and salt intake has not been investigated among these patient groups. Office BP, ABPM, augmentation index (AIx), pulse wave velocity (PWV), cardiac output (CO), and total peripheral resistance (TPR) were automatically measured. Estimation of salt intake was assessed by 24-hour urinary sodium excretion. Urinary sodium excretion was not different among groups. AIx, PWV, CO, and TPR were lowest in patients with SNT. CO was lowest while AIx adjusted for a heart rate of 75 beats per minute, PWV, and TPR were highest in the extreme dipper group. No relationship was detected between hypertension subtypes and urinary sodium excretion.

    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

    Hypertension is a common comorbidity among diabetic patients. This study aimed to determine blood pressure (BP) control among hypertensive patients with and without diabetes. This was a cross-sectional study in 6 public primary care clinics in Wilayah Persekutuan, Malaysia. Hypertensive patients aged ≥18 years and attending the clinics were selected via systematic random sampling. The BP control target was defined as <130/80 mm Hg for diabetic patients and <140/90 mm Hg for nondiabetic patients. A total of 1107 hypertensive patients participated in this study and 540 (48.7%) had diabetes. About one fourth (24.3%) of the hypertensive patients with diabetes achieved BP control target, compared with 60.1% patients without diabetes (P < .001). Being diabetic and on ≥2 antihypertensive treatments were associated with poor BP control. Attention needs to be given to these groups of patients when managing patients with hypertension.

    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.

    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

    Objective Growing evidence suggests high levels of comorbidity between hypertension and mental illness but there are few data from low- and middle-income countries. We examined the association between hypertension and depression and anxiety in South Africa. Methods Data come from a nationally-representative survey of adults (n = 4351). The Composite International Diagnostic Interview was used to measure DSM-IV mental disorders during the previous 12-months. The relationships between self-reported hypertension and anxiety disorders, depressive disorders and comorbid anxiety-depression were assessed after adjustment for participant characteristics including experience of trauma and other chronic physical conditions. Results Overall 16.7% reported a previous medical diagnosis of hypertension, and 8.1% and 4.9% were found to have a 12-month anxiety or depressive disorder, respectively. In adjusted analyses, hypertension diagnosis was associated with 12-month anxiety disorders [Odds ratio (OR) = 1.55, 95% Confidence interval (CI) = 1.10–2.18] but not 12-month depressive disorders or 12-month comorbid anxiety-depression. Hypertension in the absence of other chronic physical conditions was not associated with any of the 12-month mental health outcomes (p-values all <0.05), while being diagnosed with both hypertension and another chronic physical condition were associated with 12-month anxiety disorders (OR = 2.25, 95% CI = 1.46–3.45), but not 12-month depressive disorders or comorbid anxiety-depression. Conclusions These are the first population-based estimates to demonstrate an association between hypertension and mental disorders in sub-Saharan Africa. Further investigation is needed into role of traumatic life events in the aetiology of hypertension as well as the temporality of the association between hypertension and mental disorders.

    Hypertension and obesity often coexist, exposing patients to cardiovascular and metabolic risks, particularly type 2 diabetes mellitus. Moreover, obesity may render hypertensive patients treatment resistant. We review how drugs recently approved for obesity or type 2 diabetes mellitus treatment affect blood pressure. The weight-reducing drug lorcaserin induces modest reductions in body weight while slightly improving blood pressure. The fixed low-dose topiramate/phentermine combinations elicit larger reductions in body weight and blood pressure. Concomitant improvements in glucose metabolism, adiposity, and blood pressure differentiate the first clinically available SGLT2 inhibitor dapagliflozin from other oral antidiabetic drugs. Yet, the mechanisms through which metabolic drugs affect blood pressure and their interaction with antihypertensive drugs are poorly understood. Blood pressure-lowering effects of metabolic drugs could be exploited in the clinical management of obese hypertensive patients with and without type 2 diabetes mellitus, particularly in patients with difficult to control arterial hypertension.

    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

    BACKGROUND Early detection of subclinical left ventricular (LV) systolic dysfunction in hypertensive patients is important for the prevention of progression of hypertensive heart disease. METHODS We studied 60 hypertensive patients (age ranged from 21 to 49 years, the duration of hypertension ranged from 1 to 18 years) and 30 healthy controls, all had preserved left ventricular ejection fraction (LVEF), detected by two-dimensional speckle tracking echocardiography (2D-STE). RESULTS There was no significant difference between the two groups regarding ejection fraction (EF) by Simpson’s method. Systolic velocity was significantly higher in the control group, and global longitudinal strain was significantly higher in the control group compared with the hypertensive group. In the hypertensive group, 23 of 60 patients had less negative global longitudinal strain than −19.1, defined as reduced systolic function, which is detected by 2D-STE (subclinical systolic dysfunction), when compared with 3 of 30 control subjects. CONCLUSION 2D-STE detected substantial impairment of LV systolic function in hypertensive patients with preserved LVEF, which identifies higher risk subgroups for earlier medical intervention.

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).

    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.

    Background Isolated nocturnal hypertension (INH) has been studied among the general population and hypertensive patients. However, little insight is available on the prevalence of INH and its role in target-organ damage among patients with chronic kidney disease (CKD). Methods and Results We recruited 1282 CKD patients admitted to our hospital division. Patients were divided into 4 groups: INH; isolated daytime hypertension; day–night sustained; and ambulatory normotension. Multiple linear regression analyses were used to evaluate the correlation between INH and renal/cardiovascular parameters. A total of 262 (20.44%) CKD patients had isolated nocturnal hypertension and 651 (50.78%) had day–night sustained hypertension, whereas only 350 (27.30%) patients showed normotension and 19 (1.48%) had isolated daytime hypertension. Multivariate logistic regression analysis showed that INH was associated mainly with age, estimated glomerular filtration rate, clinic diastolic blood pressure, and that INH was determined only by age, estimated glomerular filtration rate, and clinic diastolic blood pressure. The prevalence of impaired renal function, left ventricular hypertrophy, and carotid intima-media thickness in patients with INH were higher than in normotensive patients (P<0.05), whereas impaired renal function and left ventricular hypertrophy in these patients were lower than patients in the day–night sustained hypertension group (P<0.05). INH was correlated with estimated glomerular filtration rate, left ventricular mass index, and carotid intima-media thickness according to multiple linear regression analyses. Conclusions The prevalence of INH in CKD patients was high, and INH was correlated with target-organ damage in CKD patients. PMID:26089178

    Although obesity and insulin resistance are closely correlated, their temporal sequences in early life and influence on adult hypertension are largely unknown. This study aims to delineate the temporal relationship patterns between body mass index (BMI) and insulin in childhood and their impact on adult hypertension. The longitudinal cohort consisted of 990 adults (630 whites and 360 blacks) who had BMI and fasting insulin measured twice 5.4 years apart in childhood (mean age, 10.5 years at baseline and 15.9 years at follow-up) and blood pressure measured 14.7 years later in adulthood (mean age, 30.5 years). Cross-lagged panel and mediation analysis models were used to examine the temporal relationship between childhood BMI and insulin and its impact on adult hypertension. After adjusting for age, race, sex, and follow-up years, the cross-lagged path coefficient (β=0.33; P<0.001) from baseline BMI to follow-up insulin was significantly greater than the path coefficient (β=-0.02; P>0.05) from baseline insulin to follow-up BMI in childhood with P<0.001 for the difference in βs. Blacks and whites showed similar patterns of the temporal relationship. The path coefficient (β=0.59; P<0.001) from BMI to insulin in the hypertensive group was significantly greater than that (β=0.24; P<0.001) in normotensive group, with P<0.001 for the difference in βs between these 2 groups. The mediation effect of childhood insulin on the childhood BMI-adult hypertension association was estimated at 21.1% (P<0.001). These findings provide evidence that higher BMI levels precede hyperinsulinemia during childhood, and this 1-directional relation plays a role in the development of hypertension. PMID:27432860

    BACKGROUND: There is a lack of evidence regarding the value of tools designed to aid decision making in patients with newly diagnosed hypertension. AIM: To evaluate two interventions for assisting newly diagnosed hypertensive patients in the decision whether to start drug therapy for reducing blood pressure. DESIGN OF STUDY: Factorial randomised controlled trial. SETTING: Twenty-one general practices in south-west England, UK. METHOD: Adults aged 32 to 80 years with newly diagnosed hypertension were randomised to receive either: (a) computerised utility assessment interview with individualized risk assessment and decision analysis; or (b) information video and leaflet about high blood pressure; or (c) both interventions; or (d) neither intervention. Outcome measures were decisional conflict, knowledge, state anxiety, intentions regarding starting treatment, and actual treatment decision. RESULTS: Of 217 patients randomised, 212 (98%) were analysed at the primary follow-up (mean age = 59 years, 49% female). Decision analysis patients had lower decisional conflict than those who did not receive this intervention (27.6 versus 38.9, 95% confidence interval [CI] for adjusted difference = -13.0 to -5.8, P < 0.001), greater knowledge about hypertension (73% versus 67%, adjusted 95% CI = 2% to 9%, P = 0.003) and no evidence of increased state anxiety (34.8 versus 36.8, adjusted 95% CI = -5.6 to 0.1, P = 0.055). Video/leaflet patients had lower decisional conflict than corresponding controls (30.3 versus 36.8, adjusted 95% CI = -7.4 to -0.6, P = 0.021), greater knowledge (75% versus 65%, adjusted 95% CI = 6% to 13%, P < 0.001) and no evidence of increased state anxiety (35.7 versus 36.1, adjusted 95% CI = -3.9 to 1.7, P = 0.46). There were no differences between either of the interventions and their respective controls in the proportion of patients prescribed antihypertensive medication (67%). CONCLUSIONS: This trial demonstrates that, among patients facing a real treatment

    2014-01-01

    Background In 2013 the World Health Organization deemed hypertension as a global crisis as it is the leading risk factor attributed to global mortality. Therefore, there is a great need for effective alternative treatment strategies to combat a condition that affects 40% of adults worldwide. Recently, the FlaxPAD Trial observed a significant reduction in systolic and diastolic blood pressure in hypertensive patients with peripheral arterial disease that consumed 30 g of milled flaxseed per day for one year. However, these patients were already on anti-hypertensive medication. Therefore, there is a need to assess if dietary flaxseed can effectively reduce blood pressure in the absence of peripheral arterial disease and anti-hypertensive medication in newly diagnosed hypertensive patients. Methods/Design The HYPERFlax Trial is a parallel, superiority, phase II/III, randomized, double-blinded, controlled clinical trial. St. Boniface Hospital and the Health Sciences Centre of Winnipeg, Canada, will recruit 100 participants newly diagnosed with stage 1 hypertension who have yet to be administered anti-hypertensive medication. Participants will be randomly allocated with a 1:1 ratio into a flaxseed or control group and provided food products to consume daily for six months. At baseline, two, four, and six months, participant assessments will include the primary outcome measure, averaged automated blood pressure, and secondary measures: 24-hour food recall, international physical activity questionnaire, anthropometrics, and blood and urine sampling for biochemical analysis. Plasma will be assessed for lipids, metabolomics profiling, and molecules that regulate vascular tone. Urine will be collected for metabolomics profiling. With an estimated dropout rate of 20%, the trial will have a power of 0.80 to detect differences between groups and across time, out of an effect size of 0.7 (SD) at an α level of 0.05.

    The diagnosis of cystic fibrosis (CF) is being made with increasing frequency in adults. Patients with CF diagnosed in adulthood typically present with respiratory complaints, and often have recurrent or chronic airway infection. At the time of initial presentation individuals may appear to have clinical manifestation limited to a single organ, but with subclinical involvement of the respiratory tract. Adult-diagnosed patients have a good response to CF center care, and newly available cystic fibrosis transmembrane receptor-modulating therapies are promising for the treatment of residual function mutation, thus increasing the importance of the diagnosis in adults with unexplained bronchiectasis.

    Abstract Overweight and obesity are associated with adverse cardiovascular outcomes. However, the role of overweight and obesity in left ventricular hypertrophy (LVH) of hypertensive patients is controversial. The aim of the current meta-analysis was to evaluate the influence of overweight and obesity on LVH regression in the hypertensive population. Twenty-eight randomized controlled trials comprising 2403 hypertensive patients (mean age range: 43.8–66.7 years) were identified. Three groups were divided according to body mass index: normal weight, overweight, and obesity groups. Compared with the normal-weight group, LVH regression in the overweight and obesity groups was more obvious with less reduction of systolic blood pressure after antihypertensive therapies (P < 0.001). The renin–angiotensin system inhibitor was the most effective in regressing LVH in overweight and obese hypertensive patients (19.27 g/m2, 95% confidence interval [15.25, 23.29], P < 0.001), followed by β-blockers, calcium channel blockers, and diuretics. In the stratified analysis based on blood pressure measurement methods and age, more significant LVH regression was found in 24-h ambulatory blood pressure monitoring (ABPM) group and in relatively young patients (40–60 years’ old) group (P < 0.01). Overweight and obesity are independent risk factors for LVH in hypertensive patients. Intervention at an early age and monitoring by ABPM may facilitate therapy-induced LVH regression in overweight and obese hypertensive patients. PMID:25437025

    Adiposity and insulin resistance are closely associated with hypertension. This study aims to investigate whether the association between adiposity and hypertension is modified by insulin resistance. The cohort consisted of 1624 middle-aged normotensive black and white adults aged 18 to 43 years at baseline who followed for 16 years on average. Overweight/obesity at baseline was defined as body mass index (BMI) ≥25, and insulin resistance was measured using homeostasis model assessment of insulin resistance. Prevalence of incident hypertension was compared between the insulin-sensitive adiposity and insulin-resistant adiposity groups. The prevalence of incident hypertension was higher in the insulin-resistant adiposity than in the insulin-sensitive adiposity group (32.1% versus 22.1%, P<0.001). In multivariable logistic analyses, adjusted for baseline age, race, sex, follow-up years, and smoking, baseline insulin-resistant obesity was associated with incident hypertension (odds ratio, 1.9; P=0.008). Odds ratios did not differ between blacks and whites (P=0.238). Of note, the odds ratios of BMI associated with hypertension significantly increased with increasing quartiles of baseline homeostasis model assessment (odds ratio, 1.3, 1.1, 1.5, and 2.5 in quartiles I, II, III, and IV, respectively; P=0.006 for trend). Slopes of increasing follow-up blood pressure with baseline BMI, measured as regression coefficients (β), were significantly greater in insulin-resistant than in insulin-sensitive individuals (β=0.74 versus β=0.35 for systolic blood pressure, P=0.004 for difference; β=0.51 versus β=0.23 for diastolic blood pressure, P=0.001 for difference). These findings suggest that insulin resistance has a synergistic effect on the obesity-hypertension association in young adults, indicating that the role of adiposity in the development of hypertension is modified by insulin resistance.

    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.

    Objective Despite the success of the collaborative care approach on chronic disease outcomes; many patients fail to adopt the behaviors necessary to manage their disease. Goal-setting is an approach to collaborative chronic care that involves the setting of goals for the activation and maintenance of specific self-care behaviors. Using patients' perspectives this study will describe how goals for the self-management of hypertension are developed and whether they conform to the characteristics of effective goal setting. Methods Qualitative methodology was used to explore the process of setting self-management goals for hypertensive patients. Thirty patients participated in semi-structured interviews based on the deductive framework of goal setting. Results Patients understand the risks associated with hypertension, have intentions to control their disease, report conducting at least one self-care task, and set informal goals for themselves; however these goals lack the characteristics needed to initiate and maintain behavior change. Conclusion goal setting is applicable to chronic hypertension care. Future studies need to examine ways to minimize barriers to effective goal setting to improve hypertension control. Practice implications as part of the process of chronic hypertension care, health care providers should include time and support for dedicated goal setting to improve the effectiveness of self-management behaviors.

    2014-06-01

    The combination of obesity and hypertension is associated with high morbidity and mortality because it leads to cardiovascular and kidney disease. Potential mechanisms linking obesity to hypertension include dietary factors, metabolic, endothelial and vascular dysfunction, neuroendocrine imbalances, sodium retention, glomerular hyperfiltration, proteinuria, and maladaptive immune and inflammatory responses. Visceral adipose tissue also becomes resistant to insulin and leptin and is the site of altered secretion of molecules and hormones such as adiponectin, leptin, resistin, TNF and IL-6, which exacerbate obesity-associated cardiovascular disease. Accumulating evidence also suggests that the gut microbiome is important for modulating these mechanisms. Uric acid and altered incretin or dipeptidyl peptidase 4 activity further contribute to the development of hypertension in obesity. The pathophysiology of obesity-related hypertension is especially relevant to premenopausal women with obesity and type 2 diabetes mellitus who are at high risk of developing arterial stiffness and endothelial dysfunction. In this Review we discuss the relationship between obesity and hypertension with special emphasis on potential mechanisms and therapeutic targeting that might be used in a clinical setting.

    This study aimed to estimate the relationship between various lipid abnormalities and albuminuria in hypertensive Korean adults. Data obtained from the Korea National Health and Nutrition Examination Survey in 2011 to 2012 were analyzed. The study included 2330 hypertensive participants. Total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) levels were measured. Dyslipidemia parameters were defined as high TG ≥200 mg/dL, low HDL-C as HDL-C <40 mg/dL, high TC/HDL-C as TC/HDL-C ratio ≥4, high TG/HDL-C as TG/HDL-C ratio ≥3.8, and high LDL-C/HDL-C as LDL-C/HDL-C ratio ≥2.5. Albuminuria was defined as a urine albumin to creatinine ratio (ACR) ≥30 mg/g. Women with albuminuria showed significantly higher levels of TG, TC/HDL-C, and TG/HDL-C and a lower level of HDL-C than women without albuminuria (all P < 0.05). LogTG, TC/HDL-C, and logTG/HDL-C were positively correlated with ACR in both men and women; however, HDL-C was negatively correlated with ACR in women and non-HDL-C was positively correlated with ACR in men. In men, there was no association between ACR and lipid parameters. However, in women, higher values for logTG, TC/HDL-C, and logTG/HDL-C were associated with an increased odds ratio (OR) for albuminuria (OR [95% confidence interval]: 1.53 [1.06-2.21], 1.21 [1.02-1.45], and 1.78 [1.21-2.63], respectively) and HDL-C with a decreased OR for albuminuria (0.78 [0.67-0.92]) after adjusting for all covariates. LogTG, TC/HDL-C, and logTG/HDL-C were associated with an increased prevalence of albuminuria in hypertensive women. Screening and treatment for dyslipidemia may be necessary for hypertensive women to address potential albuminuria. PMID:27100412

    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

    We studied the relationships between the blood serum levels of human leukemia differentiation factor HLDF, idiotypic and anti-idiotypic antibodies to HLDF, and clinical indicators of cardiovascular function in apparently healthy individuals and patients with essential hypertension and cerebral hypertensive crisis. Markedly reduced HLDF levels and anti-HLDF antibody titers were found in the blood of the examined patients. Correlations between HLDF levels, duration of hypertension, and systolic and diastolic BP were revealed. These findings suggest that the studied molecular factors are involved in the mechanisms of BP regulation under normal conditions and during hypertension development. The protein HLDF and anti-HLDF antibodies can be considered as biomarkers for early diagnosis of hypertension and its cerebral complications.

    Association between epistaxis and hypertension is controversial. In this study, we evaluated in hypertensive patients the incidence of epistaxis according to stages of hypertension and compared blood pressure (BP) readings in these episodes to routine readings. Thirty-six patients admitted to the Emergency Department (ED) with epistaxis were enrolled and divided into 3 groups according to hypertension severity (JNC-VI criteria). BP readings were obtained weekly (routine BP) and in the setting of a new episode of epistaxis (epistaxis BP). No difference in the incidence of epistaxis was found: patients with hypertension stage 1 had 7.6+/-4.1 episodes/year, those in stage 2 had 8.0+/-4.0 and in stage 3 the incidence was 8.2+/-3.9 (p=ns). The average SBP for all 36 patients was 154+/-19 mmHg on routine readings and 157+/-22 mmHg on epistaxes episodes (p=ns). No difference was also observed regarding DBP: 104+/-18 mmHg vs. 105+/-18 mmHg (p=ns). In conclusion, epistaxis incidence in hypertensive patients is not associated to hypertension severity. Moreover, BP readings in the setting of epistaxis are similar to readings obtained in routine situations. PMID:18499285

    INTRODUCTION: Chronic thromboembolic pulmonary hypertension is a disease affecting approximately 4,000 people per year in the United States. The incidence rate in Brazil, however, is unknown. The estimated survival for patients with chronic thromboembolic pulmonary hypertension without treatment is approximately three years. Pulmonary thromboendarterectomy for select patients is a potentially curative procedure when correctly applied. In Brazil, the clinical and hemodynamic profiles of chronic thromboembolic pulmonary hypertension patients have yet to be described. OBJECTIVES: To evaluate the clinical and hemodynamic characteristics of chronic thromboembolic pulmonary hypertension patients scheduled for pulmonary thromboendarterectomy in a referral center for chronic thromboembolic pulmonary hypertension treatment in Brazil. METHODS: From December 2006 to November 2009, patients were evaluated and scheduled for pulmonary thromboendarterectomy. The subjects were classified according to gender, age and functional class and were tested for thrombofilia and brain natriuretic peptide levels. RESULTS: Thirty‐five consecutive chronic thromboembolic pulmonary hypertension patients were evaluated. Two patients tested positive for schistosomiasis, and 31 were enrolled in the study (19 female, 12 male). The majority of patients were categorized in functional classes III and IV. Hemodynamic data showed a mean pulmonary vascular resistance (PVR) of 970.8 ± 494.36 dynas·s·cm‐5 and a low cardiac output of 3.378 ± 1.13 L/min. Linear regression revealed a direct relation between cardiac output and pulmonary vascular resistance. Paradoxical septal movement was strongly correlated with pulmonary vascular resistance and cardiac output (p = 0.001). Brain natriuretic peptide serum levels were elevated in 19 of 27 patients. CONCLUSIONS: In a referral center for pulmonary hypertension in Brazil, chronic thromboembolic pulmonary hypertension patients evaluated for pulmonary

    Objective To assess the impacts of inclusion of care for spontaneous demands in the treatment of hypertensive patients in primary health care. Methods Third generation qualitative assessment survey conducted with 16 workers in a Primary Care Health Unit (PHCU) of the city of Fortaleza, state of Ceara, in the period between July and September of 2015. To collect data, systematic field observation and semi-structured interviews were used, and the stages of thematic content analysis were adopted for data analysis. Results Participants revealed that access, connection and care are fundamental to the treatment of hypertension. However, they said that the introduction of free access for spontaneous demands compromised the flow of care in the hypertension programs. Conclusion A dichotomy between the practice of care recommended by health policies and the one existing in the reality of PHCUs was shown, causing evident losses to the care of hypertensive patients in primary care.

    The study was to evaluate the quality of self-report of hypertension and examine the factors associated with under- and over-reporting of hypertension in older Taiwanese. Data for this analysis were from the Social Environment and Biomarkers Study in Taiwan 2000, which involved a national sample of 1021 Taiwanese over 54 years of age. We performed binary classification tests to compare the prevalence rates of self-reported vs. clinically measured hypertension according to World Health Organization (WHO) (blood pressure ≥ 160/95 mm Hg or on hypertension medication) and JNC-6 (140/90 mm Hg or on hypertension medication) definitions. Logistic regression analysis was performed to analyze the potential factors associated with under- or over-reporting of blood pressure status. Results showed the test characteristics of self-reports were: sensitivity 73%, specificity 93%, and kappa = 0.68 (p < 0.001) based on the WHO definition; and sensitivity 51%, specificity 95% and kappa = 0.43 (p < 0.001) based on the JNC-6 definition. Old age was associated with over-reporting whereas having no health checkup during the past 12 months was associated with under-reporting. The relatively low agreement between self-reports and clinically measured hypertension (JNC-6 definition) was mainly due to the lack of a well-defined hypertension practice guideline and the failure of clinicians to clearly inform patients of their diagnoses. The consistency of hypertension practice guidelines and the effectiveness of informing the patients of their diagnoses are two main factors impacting the quality of self-report of hypertension in elderly Taiwanese. Better self-reports of health data can improve the efficiency of public health surveillance efforts.

    BACKGROUND—Previous fluorescein angiographic studies have shown alterations in the macular microcirculation in patients with diabetes mellitus and arterial hypertension. In both diseases capillary blood velocity was reduced and capillary density decreased. These changes were more pronounced in diabetic patients. We have examined the influence of arterial hypertension in combination with diabetes mellitus.
METHODS—62 patients with diabetes mellitus and arterial hypertension (group 1) were matched with patients with diabetes mellitus but without arterial hypertension (group 2, match criteria: ETDRS stage of retinopathy). In all subjects fluorescein angiograms were performed with a scanning laser ophthalmoscope. Macular capillary blood velocity (CBV), perifoveal intercapillary area (PIA), the coefficient of variation of both parameters, the area of the foveal avascular zone (FAZ), and the arteriovenous passage time (AVP) were assessed by digital image analysis.
RESULTS—Systolic and diastolic blood pressures were significantly increased in the patients with arterial hypertension (systolic p=0.0008; diastolic p=0.03). Neither dynamic measures (AVP: 1.64 (0.49) seconds (group 1), 1.72 (0.58) seconds (group 2); CBV: 1.98 (0.39) mm/s (group 1), 2.09 (0.43) mm/s (group 2)) nor morphological measures (PIA: 7985 (3137) µm2 (group 1), 8338 (3376) µm2 (group 2); FAZ: 0.319 (0.206) mm2 (group 1), 0.363 (0.237) mm2 (group 2)) were significantly different between the two groups of diabetic patients.
CONCLUSION—Arterial hypertension did not result in more severe macular capillary dropout than diabetes without hypertension. This might be explained by the fact that most of the patients were being treated with antihypertensive drugs.

    Hypertension is the commonest avoidable medical indication for postponing anaesthesia and surgery. There are no universally accepted guidelines stating the arterial pressure values at which anaesthesia should be postponed. The aim of this study was to determine the extent of variation across the South-West region of the UK in the anaesthetic management of patients presenting with stage 2 or stage 3 hypertension. Each anaesthetist in the region was sent a questionnaire with five imaginary case histories of patients with stage 2 or stage 3 hypertension. They were asked if they would be prepared to provide anaesthesia for each patient. The response rate was 58%. We found great variability between anaesthetists as to which patients would be cancelled. Departmental protocols may aid general practitioners and surgeons in the preparation of patients for surgery, but such protocols may be difficult to agree in the light of such a wide variation in practice.

    Dental implants surgery in patients with hypertension increases the risk of vascular complications. The aim of the study was to examine the effect of analgesia and sedation on blood pressure and postoperative pain in dental implantology. In 76 patients with hypertension implant surgery was performed under local anesthesia only (40 patients) or under local anesthesia with propofol sedation and pre-emptive analgesia with ketorolac (36 patients). Intraoperative systolic blood pressure in the second group was 20% less than in the first group while the intensity of pain in the postoperative period in the second group was three times less than in the first one. Propofol sedation in dental implantology provides hemodynamic stability in patients with concomitant hypertension and preemptive analgesia with ketorolac allows minimizing postoperative pain.

    A 28-year-old man was referred to our hospital for the treatment of congestive heart failure and severe hypertension. The patient was diagnosed with malignant phase hypertension based on the presence of marked hypertension with left ventricular hypertrophy, exudate retinopathy, and renal failure. Intensive therapy for hypertension and heart failure with a combination of antihypertensive drugs including nitroglycerin, nifedipine, eplerenone and candesartan successfully lowered his blood pressure and further improved the renal function. Eplerenone could be one of the choices of antihypertensive drugs in combination therapy in patients with malignant phase hypertension with progressive heart and renal failure.

    Objective: To synthesize the evidence for using interactive digital interventions (IDIs) to support patient self-management of hypertension, and to determine their impact on control and reduction of blood pressure. Method: Systematic review with meta-analysis was undertaken with a search performed in MEDLINE, EMBASE, CINAHL, PsycINFO, ERIC, Cochrane Library, DoPHER, TROPHI, Social Science Citation Index and Science Citation Index. The population was adults (>18 years) with hypertension, intervention was an IDI and the comparator was usual care. Primary outcomes were change in SBP and DBP. Only randomized controlled trials and studies published in journals and in English were eligible. Eligible IDIs included interventions accessed through a computer, smartphone or other hand-held device. Results: Four out of seven studies showed a significantly greater reduction for intervention compared to usual care for SBP, with no difference found for three. Overall, IDIs significantly reduced SBP, with the weighted mean difference being −3.74 mmHg [95% confidence interval (CI) −2.19 to −2.58] with no heterogeneity observed (I-squared = 0.0%, P = 0.990). For DBP, four out of six studies indicated a greater reduction for intervention compared to controls, with no difference found for two. For DBP, a significant reduction of −2.37 mmHg (95% CI −0.40 to −4.35) was found, but considerable heterogeneity was noted (I-squared = 80.1%, P = <0.001). Conclusion: IDIs lower both SBP and DBP compared to usual care. Results suggest these findings can be applied to a wide range of healthcare systems and populations. However, sustainability and long-term clinical effectiveness of these interventions remain uncertain. PMID:26845284

    Background Hypertension is associated with considerable morbidity and mortality. Improvement of its management to reduce adverse cardiovascular outcomes will require an understanding of the patient characteristics and treatment factors associated with uncontrolled blood pressure. Factors that affect blood pressure control have not been sufficiently described in Cameroon. The main goal of our study was to determine the predictors of blood pressure control in patients with hypertension in an urban city in Cameroon. Methods This was descriptive cross-sectional study from five outpatient hypertension consultation units in Hospitals in Yaoundé. Controlled hypertension was defined as blood pressure ≤140/90 mmHg. Logistic regression was used to determine factors associated with blood pressure control. Results Among the 440 patients enrolled in the survey, 280 (63.6%) were females. The mean age was 61 (SD ±11) years. Mean systolic blood pressure (SBP) was 147 mmHg and mean diastolic blood pressure (DBP) was 88 mmHg. Only 36.8% of patients had their mean blood pressure controlled (BP ≤140/90 mmHg). Multivariable logistic regression analysis revealed good adherence to anti-hypertensive medications (OR= 3.99; 95% CI: 2.20–7.23; P<0.000) and dietary lifestyle changes (OR =1.5; 95% CI: 0.53–2.49; P=0.031) to be factors independently associated with controlled hypertension. Conclusions Only one out of three patients has their blood pressure controlled. The results of our study suggest that good adherence to treatment are important factors for tight blood pressure control in primary care. Further identification of patients at risk of non-adherence to treatment and poor blood pressure control can lead to targeted interventions to reduce hypertension related morbidity and mortality in this setting.

    Despite the importance of achieving cardiometabolic goals beyond blood pressure, in the health of hypertensives, no comprehensive assessment of these characteristics has been performed in whole countries. We studied in 2008-2010 a total of 11 957 individuals representative of the Spanish population aged≥18 years. Information on cardiometabolic characteristics was collected at the participants' homes, through structured questionnaires, physical examination, and fasting blood samples. A total of 3983 individuals (33.3%) had hypertension (≥140/90 mm Hg or current antihypertensive drug treatment), 59.4% were aware of their condition, 78.8% treated among those aware, and 48.5% controlled among those aware and treated (22.7% of all hypertensives). Of the aware hypertensives, 13.8% had a body mass index<25 kg/m2, 38.6% consumed <2.4 g/d of sodium, 19.3% were diabetic with 61% attaining goal hemoglobin A1c<6.5%, whereas 42.3% had hypercholesterolemia, with 38.1% reaching goal low-density lipoprotein<115 mg/dL. Only 30.7% of overweight patients received a prescription of specific method for weight loss, 17.4% of daily smokers were offered a smoking cessation strategy, and 15.8% of older patients were given a flu shot. Aware and unaware hypertensives showed a similar frequency of some lifestyle, such as adequate physical activity. In conclusion, in a European country with a well-developed, free-access healthcare system, achievement of many cardiometabolic goals among hypertensives is poor. Moreover, a serious deficiency in hypertension awareness and in the effectiveness of some lifestyle interventions among aware hypertensives is present. Greater effort is needed in the management of coexisting risk factors and on lifestyle medical advice to improve the cardiometabolic health of hypertensives. PMID:22949530

    People of African ancestry (Blacks) have increased risk of kidney failure due to numerous socioeconomic, environmental, and clinical factors. Two variants in the APOL1 gene are now thought to account for much of the racial disparity associated with hypertensive kidney failure in Blacks. However, this knowledge has not been translated into clinical care to help improve patient outcomes and address disparities. GUARDD is a randomized trial to evaluate the effects and challenges of incorporating genetic risk information into primary care. Hypertensive, non-diabetic, adults with self-reported African ancestry, without kidney dysfunction, are recruited from diverse clinical settings and randomized to undergo APOL1 genetic testing at baseline (intervention) or at one year (waitlist control). Providers are educated about genomics and APOL1. Guided by a genetic counselor, trained staff return APOL1 results to patients and provide low-literacy educational materials. Real-time clinical decision support tools alert clinicians of their patients' APOL1 results and associated risk status at the point of care. Our academic-community-clinical partnership designed a study to generate information about the impact of genetic risk information on patient care (blood pressure and renal surveillance) and on patient and provider knowledge, attitudes, beliefs, and behaviors. GUARDD will help establish the effective implementation of APOL1 risk-informed management of hypertensive patients at high risk of CKD, and will provide a robust framework for future endeavors to implement genomic medicine in diverse clinical practices. It will also add to the important dialog about factors that contribute to and may help eliminate racial disparities in kidney disease. PMID:26747051

    Patients with resistant hypertension (RH) are at greater risk for stroke, renal insufficiency, and cardiovascular disease (CVD) events than are those for whom blood pressure (BP) is responsive to and well controlled by therapeutic interventions. Although all chronotherapy trials have compared the effects on BP regulation of full daily doses of medications when ingested in the morning versus at bedtime, prescription of the same medications in divided doses twice daily (BID) is frequent. Here, we investigated the influence of hypertension treatment-time regimen on the circadian BP pattern, degree of BP control, and relevant clinical and laboratory medicine parameters of RH patients evaluated by 48-h ambulatory BP monitoring (ABPM). This cross-sectional study evaluated 2899 such patients (1701 men/1198 women), 64.2 ± 11.8 (mean ± SD) yrs of age, enrolled in the Hygia Project. Among the participants, 1084 were ingesting all hypertension medications upon awakening (upon-awakening regimen), 1436 patients were ingesting the full daily dose of ≥1 of them at bedtime (bedtime regimen), and 379 were ingesting split doses of ≥1 medications BID upon awakening and at bedtime (BID regimen). Patients of the bedtime regimen compared with the other two treatment-time regimens had lower likelihood of microalbuminuria and chronic kidney disease; significantly lower albumin/creatinine ratio, glucose, total cholesterol, and low-density lipoprotein (LDL) cholesterol; plus higher estimated glomerular filtration rate and high-density lipoprotein (HDL) cholesterol. The bedtime regimen was also significantly associated with lower asleep systolic (SBP) and diastolic (DBP) BP means than the upon-awakening and BID regimens. The sleep-time relative SBP and DBP decline was significantly attenuated by the upon-awakening and BID regimens (p < .001), resulting in significantly higher prevalence of non-dipping in these two treatment-time regimen groups (80.5% and 77.3%, respectively

    Macitentan (Opsumit(®)) is an orally active, dual endothelin receptor antagonist (ERA) with tissue targeting properties. Macitentan was approved recently in the EU (as monotherapy or combination therapy) for the long-term treatment of pulmonary arterial hypertension (PAH) in adults of WHO functional class II or III, and in the USA for the treatment of PAH (WHO group I) to delay disease progression and reduce hospitalization for PAH. This article reviews the pharmacological properties, efficacy and tolerability data relevant to the use of macitentan in this indication. Treatment with macitentan 10 mg once daily significantly reduced the risk for the primary composite endpoint of morbidity and mortality in patients with PAH (mostly WHO functional class II or III) in the large, randomized, placebo-controlled SERAPHIN study. Other efficacy outcomes, including exercise capacity, haemodynamic parameters and health-related quality of life also improved significantly with macitentan relative to placebo. Macitentan was generally well tolerated in this study. As with other ERAs, haemoglobin levels decreased with macitentan therapy; however, these were not progressive and stabilized following longer-term treatment. Although comparative studies are needed to definitively position macitentan with respect to other approved agents, current evidence suggests that macitentan is a useful treatment option for initial therapy in patients with WHO functional class II or III PAH, which has the potential advantage of once-daily administration.

    Systemic sclerosis (SSc)-related autoantibodies are useful tools in identifying clinically homogenous subsets of patients and predicting their prognosis. In this report, we described five SSc patients with anti-centriole antibodies. All five patients were females and had digital ulcers/gangrene. Four of five (80%) patients had pulmonary arterial hypertension (PAH). None of the five patients had active pulmonary fibrosis or developed renal crisis. Anti-centriole antibodies may be a marker for PAH and digital ulcers/gangrene.

    Objectives . To determine the risk factors for arterial hypertension (HTN) in the adult resident population of the city of Cuenca, Ecuador Materials and methods A cross-sectional analytical study of adults selected via multistage random sampling who underwent clinical, anthropometric, and laboratory evaluations. The diagnosis of HTN was defined according to the JNC-7 criteria. A multiple logistic regression model was performed Results A total of 318 persons were included. The prevalence of HTN was 25.8% (males: 27.2% vs. females: 24.7%; p = 0.617). In the multiple logistic regression model, the risk factors for HTN were age > 60 years (OR, 8.68; 95% CI, 3.56-21.14; p < 0.001), obesity according to body mass index (OR, 2.36; 95% CI, 1.04-5.70; p = 0.042), high caloric intake (OR, 2.06; 95% CI, 1.01- 4.53; p = 0.044), and family history of HTN (OR, 1.58; 95% CI, 1.02-2.90; p = 0.040) Conclusions The presence of HTN in this population is associated with both intrinsic and environmental factors, which should be considered in routine evaluations to ensure its early identification and control.

    We have studied the percentage of 22Na+ uptake in cell suspensions; 0.4 to 2.0 x 10(9) erythrocytes/mL from diabetic uremic patients with secondary hypertension and from normal subjects. Suspensions from diabetic uremic patients with secondary hypertension 0.42 +/- 0.06 to 2.05 +/- 0.28; normal subjects showed a percentage uptake of 22Na+ of 0.27 +/- 0.05 to 1.28 +/- 0.22. The uptake of 22Na+ in 2.0 x 10(9) cells/mL was 60% more (P less than .05) in diabetic uremic patients than in the controls. These studies indicate that 22Na+ influx determinations may be used to distinguish secondary hypertensive patients from normal subjects.

    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. PMID:25477963

  16. BR 02-2 HYPERTENSION MANAGEMENT IN CANCER PATIENTS UNDERGOING CHEMOTHERAPY.

    As both the rate of hypertension and cancer rise with age, concomitant hypertension in patients receiving treatment for cancer is very common. Increase in blood pressure during cancer treatment requires careful clinical assessment. Distinction between discontinuation or malabsorption of antihypertensive treatment due to factors such as nausea/vomiting/diarrhea and anti-cancer drug specific effects must be first made. De-novo hypertension during cancer treatment is likely related to anticancer drugs per se. Classical chemotherapeutic agents such as cyclophosphamide, cisplatin and busulfan have been previously linked to rising blood pressure. The concomitant use of high doses of glucocorticoids in some chemotherapy protocols may have a contributory role. However, the recent surge of interest in cancer treatment-related hypertension has been generated by the use of growth receptors' signaling cascade inhibitors. Hypertension or deterioration in the control of hypertension may be seen in as much as 80% of patients receiving VEGF signaling pathway inhibitors. Agents may target one or more types of VEGF receptors, FGF-, PDGF- and hepatic growth factor receptors; RET and/or signaling elements such as RAF, BRAF, Flt3 and c-KIT. Indeed, at least some rise in blood pressure is actually expected in every patient subjected to this treatment but the rate of evolution of hypertension is variable. Risk factors for significant increase in BP include the type of agent and its dosage, the existence of preceding hypertension, age>60yrs and overweight/obesity. Hypertension may also be more common in subjects previously treated with programmed cell death 1 (PD-1) pathway inhibitors. Potential mechanisms of hypertension include impaired endothelial cell function with decreased NO synthesis and effect with increased endothelin-1 formation; decreased capillary density; increased salt sensitivity; and renal impairment. Hypertension due to VEGF/tyrosine kinase inhibitors is not only common

    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

    Background A low rate of blood pressure control has been reported among patients with chronic kidney disease (CKD). These data were derived from population-based samples with a low rate of CKD awareness. Study Design Cross-sectional Setting & Participants Data from the baseline visit of the Chronic Renal Insufficiency Cohort (CRIC) study (n=3612) were analyzed. Participants with an estimated glomerular filtration rate of 20 to 70 ml/min/1.73m2 were identified from physician offices and review of laboratory databases. Outcomes Prevalence and awareness of hypertension, treatment patterns, control rates and factors associated with hypertension control. Measurements Following a standardized protocol, blood pressure was measured three times by trained staff and hypertension was defined as systolic blood pressure ≥140 mmHg and/or diastolic blood pressure ≥90 mmHg and/or self-reported antihypertensive medication use. Patients’ awareness and treatment of hypertension were defined using self-report and two levels of hypertension control were evaluated: systolic/diastolic blood pressure <140/90 mmHg and <130/80 mmHg. Results The prevalence of hypertension was 85.7%, and 98.9% of CRIC participants were aware of this diagnosis, 98.3% were treated with medications while 67.1% and 46.1% had their hypertension controlled to <140/90 mmHg and <130/80 mmHg, respectively. Of CRIC participants with hypertension, 15%, 25%, 26% and 32% were taking one, two, three and four or more antihypertensive medications, respectively. After multivariable adjustment, older patients, blacks, those with higher urinary albumin excretion were less likely while participants taking ACE-inhibitors and angiotensin receptor blockers were more likely to have controlled their hypertension to <140/90 mmHg and <130/80 mmHg. Limitations Data were derived from a single study visit. Conclusions Despite almost universal hypertension awareness and treatment in this cohort of patients with CKD, rates of

    It was determined the characteristics of lipid status of patients with essential hypertension, abdominal obesity with concomitant subclinical hypothyroidism--mostly increased levels of total and LDL cholesterol. In assessing the effectiveness of statin therapy in combination with levothyroxine replacement therapy compared with statin monotherapy, combination therapy showed the best result in terms of achievement of target levels of both total cholesterol and LDL. The obtained results allow us to recommend the use of combination therapy for patients with hypertension, abdominal obesity with concomitant subclinical hypothyroidism in order to achieve the target values of LDL and thus to reduce the cardiovascular risk of these patients.

    For hypertensive patients with renal diseases (RD), strict blood pressure (BP) control has been recommended in recent hypertension guidelines, such as JNC VI, JNC 7, WHO/ISH 1999 and ESH-ESC 2003. We assessed the current status of BP control and the changes of BP control before and after the publication of these guidelines in 489 hypertensive patients with or without RD (age, 19-89 years, mean 59+/-13 years) who visited the hypertension and kidney outpatient clinic at Kyushu University Hospital. The clinical characteristics of RD and non-RD patients were assessed (RD patients: age, 20-89 years, mean 60+/-13 years, n=311; non-RD patients: age, 19-86 years, mean 58+/-13 years, n=178). In addition, we compared the BP control status in 2003 to that in 1996. In 2003, the BP in RD patients was 134+/-16/78+/-10 mmHg and that in non-RD patients was 138+/-12/83+/-9 mmHg. When strict BP control was defined as <130/80 mmHg, the frequency of strict BP control in RD patients was 28.9% in 2003. In addition, the BP levels of RD patients in 2003 were significantly lower than those in 1996 (134+/-16/78+/-10 mmHg vs. 141+/-17/85+/-10 mmHg, p<0.05 for both systolic blood pressure [SBP] and diastolic blood pressure [DBP]), and the frequency of strict BP control in RD patients was higher in 2003 than in 1996 (28.9% vs. 11.8%, p<0.01). The BP levels of non-RD patients in 2003 tended to be lower than those in 1996 (138+/-12/83+/-9 mmHg vs. 141+/-13/85+/-9 mmHg, n.s.). In 2003, angiotensin II receptor blockers (ARBs) were more frequently prescribed to RD patients than to non-RD patients. Furthermore, the use of ARBs was markedly increased in 2003 compared with 1996. In conclusion, in our outpatient clinic, BP levels in hypertensive patients with RD have improved in recent years, and were lower than those in hypertensive patients without RD, which may in part reflect the physicians' awareness of the importance of strict BP control in RD patients, as suggested by several recent hypertension

    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.

    In this study we examined whether the reduced fibrinolysis and increased platelet activity that are known to occur in hypertension are already present in borderline hypertension. Twelve patients with 'borderline' hypertension (diastolic blood pressure 90-95 mmHg) were found to have substantially reduced fibrinolytic activity, both at rest and during exercise, compared with 12 normotensive controls. Euglobulin clot lysis time (ECLT) was significantly higher in hypertensive subjects (218 min vs. 145 min; P < 0.05), and this difference persisted during exercise. Resting tissue plasminogen activator activity (t-PA) did not differ in the two groups, but the brisk increase in t-PA in controls during exercise (0.64 rising to 1.44 IU mL-1; P < 0.01) did not occur to the same extent in the borderline hypertensive subjects. Levels of the fast-acting t-PA inhibitor, normally referred to as PAI-1, were considerably higher in hypertensives (9.22 vs. 4.41 IU mL-1; P < 0.02), and this difference persisted in the upright posture, indicating a decrease in fibrinolytic activity. Platelet aggregability induced by ADP in vitro was not significantly higher in the hypertensive subjects, but indices of platelet activity in vivo (B-TG and PF-4 levels) revealed enhanced platelet function in the hypertensives. These results indicate that the indicators of altered haemostatic function known to occur in hypertension, namely diminished fibrinolytic activity and increased platelet function, are already detectable during the very earliest stage of the disease.

    Non-Hispanic Asian adults constituted 4.9% of the U.S. population in 2012, corresponding to 15.4 million people (2). This group primarily comprises persons of Chinese, Asian Indian, Korean, Filipino, Vietnamese, and Japanese descent. The prevalence of hypertension (defined as having blood pressure greater than or equal to 140/90 mm Hg or taking blood pressure-lowering medications) among non-Hispanic Asian adults aged 20 and over was 25.6%. As previously reported, this prevalence is similar to that of non-Hispanic white adults and Hispanic adults but lower than that of non-Hispanic black adults (3). Among non-Hispanic Asian adults, the prevalence of hypertension was higher among those who were older or had less education, similar to findings in U.S. adults overall (4,5). The prevalence of high total cholesterol (measured as cholesterol of at least 240 mg/dL) among non-Hispanic Asian adults was similar to that among adults of other race and Hispanic origin groups (6). Non-Hispanic Asian adults had a lower prevalence of low HDL cholesterol (measured as HDL less than 40 mg/dL) than Hispanic persons (6). Non-Hispanic Asian adult men were almost five times more likely than non-Hispanic Asian adult women to have low HDL cholesterol. While adult men in general are known to have a higher prevalence of low HDL cholesterol than adult women (7), the sex difference was larger than in other race and Hispanic origin groups (6). The prevalence of high BMI among non-Hispanic Asian adults (38.6%) was much lower than that previously reported for non-Hispanic white adults (66.7%), non-Hispanic black adults (76.7%), and Hispanic adults (78.8%) (8). BMI is widely used as a measure of body fat. However, at a given BMI level, body fat may vary by sex, age, and race and Hispanic origin. In particular, at a given BMI, Asian adults may have more body fat than white adults (9). Also, morbidity and mortality risk may be influenced by body composition and fat distribution in a manner that is

    The role of α1D-adrenoceptors in the vasculature of spontaneously hypertensive (SHR) and normotensive Wistar Kyoto rats (WKY), of different ages was assessed in pithed rats by the use of the selective α1D-adrenoceptor antagonist BMY 7378 (8-[2-[4-(2-methoxyphenyl)-1-piperazinyl]-ethyl]-8-azaspiro [4.5]decane-7,9-dione dihydrochloride). BMY 7378 displaced the pressor effect of phenylephrine in young pre-hypertensive pithed SHR rats, but produced no effect in young WKY rats (dose ratio of 3.4 and 1.6, respectively), while in adult rats BMY 7378 produced a greater shift in the phenylephrine response curve than in younger animals (dose ratio of 3.2 and 6.2 in WKY and SHR, respectively). The presence of α1D-adrenoceptors in the vasculature of pre-hypertensive rats, suggests its role in the pathogenesis/maintenance of increased blood pressure. PMID:10323583

    Background: The aim of this study was to assess the predictive capacity of body composition estimated by bioelectrical impedance analysis (BIA) to identify abnormal blood pressure in physical education and sport teaching students in the city of Ankara. Methods: Data for this cross-sectional study were obtained in the city of Ankara in 2014. A total of 133 students aged 20–35 yr participated in this study. Anthropometric measurements were measured. Body composition was assessed by BIA. Physical activity level (PAL) and usual dietary intake were assessed. Pre-hypertension and hypertension were defined, respectively, as BP ≥120 and/or 80, and ≥140 and /or 90 mmHg. Results: More overweight students showed abnormal BP especially SBP (P=0.005 and 0.002, respectively). Age adjusted regression showed significant association between arm circumference (β= 0.176, P 0.044), mid arm muscle circumference (MAMC) (β= 0.235, P 0.007), lean body mass (LBM) (β= 0.238, P 0.006), basal metabolism rate (BMR) (β= 0.219, P 0.012) and SBP and, also, MAMC (β= 0.201, P 0.022), LBM (β= 0.203, P 0.021), BMR (β= 0.189, P 0.030) and DBP. Fat intake was associated with DBP (β= 0.14, P =0.040). Multivariate regression models adjusted for age, BMI, WC and fat intake/kg body weight showed positive association of SBP with MAMC, BMR and LBM (P<0.05). Conclusion: The relationship between blood pressure and body composition in young adults may be associated to LBM and MAMC. LBM or MAMC in this population may be indirect indicators of heart muscle mass and heart pumping power. PMID:26811815

    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.

    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. PMID:25492834

    Background Hypertension is a global health problem. Multiple classes of drugs including angiotensin receptor blockers (ARBs) are available for the treatment of hypertension. Olmesartan is a relatively newer ARB used in hypertension management. Objective To assess the efficacy and safety of WIN-BP (Olmesartan 20 mg/40 mg) tablet in Indian patients with hypertension. Material and methods An open label, non-comparative, multi-centric, real world post marketing observational study included Indian adult hypertensive patients who were treated with olmesartan 20 mg/40 mg tablet once daily for six months. The primary outcome was reduction of systolic blood pressure (SBP) to <140 mmHg and diastolic BP (DBP) to <90 mmHg at 3 and 6 months after initiation of treatment with olmesartan. All reported adverse events were recorded. Results A total of 8940 patients were enrolled in this study. Baseline SBP of 164 mmHg was reduced to 153, 145, 134 and 130 mmHg at the end of 15 days, 1, 3 and 6 months respectively. Similarly, baseline DBP of 100 mmHg was reduced to 93, 89, 84 and 82 mmHg at the end of 15 days, 1, 3 and 6 months respectively. The reduction in both systolic and diastolic blood pressure from day 15 to month 6 was statistically significant (p < 0.0001) with olmesartan treatment. The percentage of responders for both systolic and diastolic blood pressure increased consistently from day 15 to month 6. Only 0.08% patients reported the adverse events. No serious adverse event was reported in the study. Conclusion Olmesartan 20 mg/40 mg is effective and well tolerated without any serious adverse events in patients with hypertension. PMID:24973841

    Control of hypertension is an important cornerstone in prevention of cardiovascular morbidity and mortality. This study was designed to compare physician encounter score in patients with controlled and uncontrolled hypertension. It was conducted at three tertiary care hospitals in Karachi. Patients were categorized into controlled and uncontrolled hypertension based on their initial blood pressure readings on presentation. Primary outcome variable was control of hypertension and physician encounter score (a composite score of 12 item question) was the main candidate variable. Higher scores reflected favorable encounter with physician. Mean age of participants was 57.7 ± 12 years; 224 (50.1%) were men. Controlled hypertension was present in 72.3% (323) and uncontrolled hypertension was present in 27.4% (124). Mean physician encounter score in uncontrolled hypertensive was 7.25 ± 2.64 versus 7.83 ± 2.22 (p=0.02) in controlled hypertensive. Patient-physician encounter is an important milestone in control of hypertension in hypertensive patients and directly translates into better adherence to antihypertensives in these patients.

    Introduction: “Athlete’s heart syndrome” is a condition characterized by structural, electrophysiologic and functional adaptation of the myocardium to physical activity (training), depending on the activity intensity, duration and type. In athletes left ventricular hypertrophy often resembles comorbid conditions (hypertension or hypertrophic cardiomyopathy) so the differential diagnosis of the disease is very important and crucial, especially in people who are in active training. In fact, if an athlete has finding which indicate thickening of the left ventricle walls, should be distinguished hypertrophy which occurred as a result of many years of training from accidental existence of hypertension or hypertrophic cardiomyopathy in the same person. Therefore, it is important to make a diagnostic difference between healthy and sick heart. Material and methods: The study involved male persons aged 20-45 which have increased muscle mass of the left ventricle due to different etiology. Definite sample included 80 respondents divided into two groups. All respondent underwent interview, clinical examination, ECG and echocardiography. Results: Average systolic blood pressure (SBP) for the athletes were 115.8±7.2 mmHg, and in patients, with hypertension 154.4±3.5 mmHg, average values of diastolic blood pressure (DBP) for the athletes were 74.2±8.1 mmHg in patients, hypertensive 96.2 ± 3.9 mmHg. Values of SBP and DBP were significantly lower in the group of athletes compared to patients with hypertension (p=0.001). The value of the SFO/min was significantly lower in the group of athletes compared to patients with hypertension (p <0.001). There was a statistically significant difference in the sum of SV2 RV5 and between groups of athletes and groups of patients with hypertension (p<0.05). There was no significant difference in the echocardiography parameters between two groups. There was a statistically significant difference in the sum of SV2 and RV5 between groups

    Background Switzerland has a low mortality rate from cardiovascular diseases, but little is known regarding prevalence and management of cardiovascular risk factors (CV RFs: hypertension, hypercholesterolemia and diabetes) in the general population. In this study, we assessed 10-year trends in self-reported prevalence and management of cardiovascular risk factors in Switzerland. Methods data from three national health interview surveys conducted between 1997 and 2007 in representative samples of the Swiss adult population (49,261 subjects overall). Self-reported CV RFs prevalence, treatment and control levels were computed. The sample was weighted to match the sex - and age distribution, geographical location and nationality of the entire adult population of Switzerland. Results self-reported prevalence of hypertension, hypercholesterolemia and diabetes increased from 22.1%, 11.9% and 3.3% in 1997 to 24.1%, 17.4% and 4.8% in 2007, respectively. Prevalence of self-reported treatment among subjects with CV RFs also increased from 52.1%, 18.5% and 50.0% in 1997 to 60.4%, 38.8% and 53.3% in 2007 for hypertension, hypercholesterolemia and diabetes, respectively. Self-reported control levels increased from 56.4%, 52.9% and 50.0% in 1997 to 80.6%, 75.1% and 53.3% in 2007 for hypertension, hypercholesterolemia and diabetes, respectively. Finally, screening during the last 12 months increased from 84.5%, 86.5% and 87.4% in 1997 to 94.0%, 94.6% and 94.1% in 2007 for hypertension, hypercholesterolemia and diabetes, respectively. Conclusion in Switzerland, the prevalences of self-reported hypertension, hypercholesterolemia and diabetes have increased between 1997 and 2007. Management and screening have improved, but further improvements can still be achieved as over one third of subjects with reported CV RFs are not treated. PMID:21332996

    INTRODUCTION The aim of this study was to determine the extent to which primary care doctors assessed patients newly diagnosed with hypertension for the risk factors of cardiovascular disease (CVD) during the patients’ first clinic visit for hypertension. The study also aimed to examine the trend of assessment for CVD risk factors over a 15-year period. METHODS This retrospective study was conducted between January and May 2012. Data was extracted from the paper-based medical records of patients with hypertension using a 1:4 systematic random sampling method. Data collected included CVD risk factors and a history of target organ damage (TOD), which were identified during the patient’s first visit to the primary care doctor for hypertension, as well as the results of the physical examinations and investigations performed during the same visit. RESULTS A total of 1,060 medical records were reviewed. We found that assessment of CVD risk factors during the first clinic visit for hypertension was poor (5.4%–40.8%). Assessments for a history of TOD were found in only 5.8%–11.8% of the records, and documented physical examinations and investigations for the assessment of TOD and secondary hypertension ranged from 0.1%–63.3%. Over time, there was a decreasing trend in the percentage of documented physical examinations performed, but an increasing trend in the percentage of investigations ordered. CONCLUSION There was poor assessment of the patients’ CVD risk factors, secondary causes of hypertension and TOD at their first clinic visit for hypertension. The trends observed in the assessment suggest an over-reliance on investigations over clinical examinations. PMID:26451055

    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.

    Oxidative stress is associated with cardiac and vascular defects leading to hypertension and atherosclerosis, being superoxide dismutase (SOD) one of the main intracellular antioxidant defence mechanisms. Although several parameters of vascular function and structure have a predictive value for cardiovascular morbidity-mortality in hypertensive patients, there are no studies on the involvement of SOD serum levels with these vascular parameters. Thus, we assessed if SOD serum levels are correlated with parameters of vascular function and structure and with cardiovascular risk in hypertensive and type 2 diabetic patients. We enrolled 255 consecutive hypertensive and diabetic patients and 52 nondiabetic and nonhypertensive controls. SOD levels were measured with an enzyme-linked immunosorbent assay kit. Vascular function and structure were evaluated by pulse wave velocity, augmentation index, ambulatory arterial stiffness index, and carotid intima-media thickness. We detected negative correlations between SOD and pressure wave velocity, peripheral and central augmentation index and ambulatory arterial stiffness index, pulse pressure, and plasma HDL-cholesterol, as well as positive correlations between SOD and plasma uric acid and triglycerides. Our study shows that SOD is a marker of cardiovascular alterations in hypertensive and diabetic patients, since changes in its serum levels are correlated with alterations in vascular structure and function.

    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.

    Severe pulmonary arterial hypertension is a significant risk factor for anesthetic management in patients undergoing even non-cardiac surgery. A 64-year-old female patient with severe pulmonary arterial hypertension was scheduled to undergo inguinal hernioplasty. Preoperative systolic pulmonary arterial pressure was 115 mmHg. We selected monitored anesthesia care with 0.2-0.5 μg x kg(-1) x hr(-1) dexmedetomidine and ultrasound-guided iliohypogastric block. Thereafter, LiDCOrapid was used to acquire the hemodynamic responses during surgery. Continuous iliohypogastric block produced postoperative pain relief and the supplemental analgesic was not needed. The monitored anesthesia care by dexmedetomidine and ultrasound guided continuous iliohypogastric block would be a safe procedure for patients with severe pulmonary arterial hypertension undergoing non-cardiac surgery. LiDCO rapid could be low invasive and useful as a hemodaynamic monitor in such a case. PMID:27319099

    Hypertension is a lifelong condition; thus, long-term adherence to lifestyle modification, self-monitoring, and medication regimens remains a challenge for patients. The aim of this study was to develop a patient-reported hypertension instrument that measured attitudes, lifestyle behaviors, adherence, and barriers to hypertension management using patient-reported outcome data. The study was conducted using the Open Research Exchange software platform created by PatientsLikeMe. A total of 360 participants completed the psychometric phase of the study; incomplete responses were obtained from 147 patients, and 150 patients opted out. Principal component analysis with orthogonal (varimax) rotation was executed on a data set with all completed responses (N = 249) and applied to 43 items. Based on the review of the factor solution, eigenvalues, and item loadings, 16 items were eliminated and model with 29 items was tested. The process was repeated two more times until final model with 14 items was established. In interpreting the rotated factor pattern, an item was said to load on any given component if the factor loading was ≥0.40 for that component and was <0.40 for the other. In addition to the newly generated instrument, demographic and self-reported clinical characteristics of the study participants such as the type of prescribed hypertension medications, frequency of blood pressure monitoring, and comorbid conditions were examined. The Open Research Exchange platform allowed for ongoing input from patients through each stage of the 14-item instrument development. PMID:26369442

    The aims of this study were (1) to investigate what are the illness perceptions of hypertensive patients and their relationship with beliefs about specific medicines, and (2) to identify different illness schemata and how they relate to the choice of medication. This was a cross-sectional study in which 191 Portuguese patients (59% females), with a hypertension diagnosis, aged over 18 years old, were recruited from a hospital clinic in the Lisbon Metropolitan area. The questionnaire included measures of choice of medication, beliefs about specific medicines (BMQ-Specific), illness perception (Brief-IPQ), and socio-demographic information. The results indicated that the components of the illness perceptions were associated with patients' beliefs about necessity and concerns about medication. Patients seem to differ in their choice of medication (generic or brand names) according to the three illness schemata identified. Patients with more negative illness schemata were more likely to choose a brand medicine, whereas patients with a more positive perception of hypertension were more likely to choose a generic medicine. Our findings support the argument that illness perceptions and beliefs about medicines play a role in influencing patients' preferences of medicines for the treatment of hypertension. PMID:20204931

    Hypertension is the most common disease of the cardiovascular system. Active treatment of hypertension with adequate control of blood pressure (BP) can prevent complications, improve life quality and increase life expectancy. One of the interesting new antihypertensive agents, from the group of angiotensin receptor blockers is olmesartan. The obvious advantages of ambulatory blood pressure monitoring to traditional one-time measurements of BP make this method perspective for quality control of anti-hypertensive therapy. The aim of this study was to evaluate the influence of treatment with olmesartan on ambulatory blood pressure monitoring parameters in patients with hypertension. 38 out-patients with hypertension at the age of 25-84 years (mean 55,3±10,6) were studied. Patients received olmesartan 20 mg daily as monotherapy (20 patients (52,6%)) or in combination with other antihypertensive agents (18 patients (47,4%)). Treatment continued for 6 months. The complex examination included: measurement of office brachial BP, electrocardiography, echocardiography and ambulatory blood pressure monitoring (ABPM). As a result of treatment, office BP and diurnal BP, according to ABPM, significantly decreased; the favorable circadian BP profile dynamics were found: significantly less frequently observed lack of reduction in BP during night (daily index - non-dipper) - 18% vs. 64% (p <0,001), while the number of individuals with normal daily index (dipper) increased significantly - 76% vs. 28% (p <0,001). Also there was determined the significant reduction in daytime and nighttime systolic BP variability - by 1.5 mmHg and 2.1 mmHg, respectively, with the normalization of these parameters at the end of the observation period. The presented results allow conclude, that treatment of hypertensive patients with olmesartan provides significant decline not only in office BP, but also in diurnal BP, normalizes BP of active and passive periods, also - daily index and reduces BP

    Background The detection of hypertension in black Caribbean populations is good, but its control is thought to be inadequate. Aim To explore how black Caribbean patients with hypertension understand their condition, and the strategies they use in managing hypertension. Design of study Qualitative study using in-depth interviews. Setting One general practice in inner-city London. Method Practice records were searched to identify black Caribbean patients with known and treated hypertension. Audiotaped in-depth interviews were conducted with all identified patients and transcripts of the interviews were analysed for thematic content. Results We interviewed 19 black Caribbean patients with hypertension. Participants reported physical symptoms for elevated blood pressure; a minority relied on symptoms to determine their medicine use. A majority of participants equated ‘normal’ blood pressure readings with being cured and with no need for prescribed medicine. All participants had been prescribed antihypertension medication, and seven reported taking medication as prescribed. Those who did not, reported diverse and dynamic patterns of medication consumption. Some who had achieved normal blood pressure equated this with being cured and stopped medication, resuming when diagnosed with high blood pressure. Some modified their use of tablets according to bodily symptoms that they felt indicated higher or lower blood pressure. Some stopped or reduced medication because of unwanted effects and almost half of the participants used Caribbean ‘bush’ remedies. Conclusion These findings suggest that some patients are making reasoned decisions about blood pressure management, drawing on medical information, their own bodily experiences of illness and sociocultural notions and practices. However, this may lead to medication use that diverges from that which is recommended. This study indicates a continued need to address these patients' perspectives and develop and evaluate

    This systematic review applied meta-analytic procedures to synthesize medication adherence interventions that focus on adults with hypertension. Comprehensive searching located trials with medication adherence behavior outcomes. Study sample, design, intervention characteristics, and outcomes were coded. Random-effects models were used in calculating standardized mean difference effect sizes. Moderator analyses were conducted using meta-analytic analogues of ANOVA and regression to explore associations between effect sizes and sample, design, and intervention characteristics. Effect sizes were calculated for 112 eligible treatment-vs.-control group outcome comparisons of 34,272 subjects. The overall standardized mean difference effect size between treatment and control subjects was 0.300. Exploratory moderator analyses revealed interventions were most effective among female, older, and moderate- or high-income participants. The most promising intervention components were those linking adherence behavior with habits, giving adherence feedback to patients, self-monitoring of blood pressure, using pill boxes and other special packaging, and motivational interviewing. The most effective interventions employed multiple components and were delivered over many days. Future research should strive for minimizing risks of bias common in this literature, especially avoiding self-report adherence measures. PMID:26560139

    Hypertension in the elderly is one of the main risk factors of cardiovascular and cerebrovascular diseases. Knowledge regarding the mechanisms of hypertension and specific considerations in managing hypertensive elderly through pharmacological intervention(s) is fundamental to improving clinical outcomes. Recent clinical studies in the elderly have provided evidence that angiotensin II type 1 (AT1) receptor antagonists can improve clinical outcomes to a similar or, in certain populations, an even greater extent than other classical arterial blood pressure-lowering agents. This newer class of antihypertensive agents presents several benefits, including potential for improved adherence, excellent tolerability profile with minimal first-dose hypotension, and a low incidence of adverse effects. Thus, AT1 receptor antagonists represent an appropriate option for many elderly patients with hypertension, type 2 diabetes, heart failure, and/or left ventricular dysfunction. PMID:22915967

    In chronic thromboembolic pulmonary hypertension (CTEPH), stenoses or obstructions of the pulmonary arteries due to organized thrombi can cause an elevation in pulmonary artery resistance, which in turn can result in pulmonary hypertension. CTEPH can be cured surgically by pulmonary endarterectomy (PEA); however, patients deemed unsuitable for PEA due to lesion, advanced age, or comorbidities have a poor prognosis and limited treatment options. Recently, advances have been made in balloon pulmonary angioplasty for these patients, and this review highlights this recent progress. PMID:26664876

    Increased blood pressure was associated with increased white blood cell count (adjusted p < 0.001) in a community-based health examination survey of adults in China (n = 39 282; aged 18-93 years). Adjusted odds ratios (95% confidence intervals) for hypertension across white blood cell count quintiles were 1.00, 0.99 (0.89-1.09), 1.11 (1.01-1.22), 1.09 (0.99-1.20), and 1.19 (1.08-1.31) (p for trend < 0.001). Body mass index and white blood cell count had an additive effect on systolic blood pressure (p for interaction = 0.047). Therefore, white blood cell count could independently predict hypertension in Chinese adults.

    The antihypertensive effect of 2,000 mg of acebutolol investigated with an acute 48 hr test in 60 diabetic and 60 non-diabetic in-patients with essential hypertension. In hypertensive diabetic patients, acebutolol was induced a significant fall in blood pressure similar to that observed in non-diabetics. The acute antihypertensive effect of acebutolol was not uniform in hypertensive subjects: a significant decrease of blood pressure was observed in 34 diabetics and 31 non-diabetic patients. Fifteen out of the 34 diabetic responders to the 48 hr test were treated by acebutolol alone for six months; a highly significant correlation between the acute and the chronic antihypertensive effect of the beta-blocker was observed. As long-term results paralleled those of the short-term experiment, acute acebutolol administration appears to be a rapid means to select hypertensive diabetics sensitive or resistant to betablockers. Plasma renin activity was not found to give, in hypertensive diabetics, a reliable predictive index of the response to acute administration of acebutolol.

    Aim of this study was to evaluate the cost-effectiveness of renal denervation (RD) in resistant arterial hypertension (AH) in Russia. Modeling of Markov conducted economic impact of RD on the Russian population of patients with resistant hypertension in combination with optimal medical therapy (OMT) compared with OMT using a model developed by American researchers based on the results of international research. The model contains data on Russian mortality, and costs of major complications of hypertension. The simulation results showed a significant reduction in relative risk reduction of adverse outcomes in patients with resistant hypertension for 10 years (risk of stroke is reduced by 30%, myocardial infarction - 32%). RD saves 0.9 years of quality-adjusted life (QALY) by an average of 1 patient with resistant hypertension. Costs for 1 year stored in the application of quality of life amounted to RD 203 791.6 rubles. Which is below the 1 gross domestic product and therefore indicates the feasibility of this method in Russia.

    Background Earlier studies in Nigeria reported the rarity of retinal vascular changes in hypertensives. The aim of this study was to describe the various retinal vascular changes in the hypertensive patients of Nigeria. Patients and methods Nine hundred and three hypertensive patients were studied. This study was approved by the ethical and research committee of the University of Ibadan and University College Hospital, Ibadan, Nigeria. Blood pressure and anthropometric measurements were measured. Cardiac echocardiography was performed on 156 patients. All patients had dilated fundoscopy and fundus photography using the Kowa portable fundus camera and an Apple iPhone with 20 D lens. Statistical analysis was done with Statistical Packages for the Social Sciences (Version 21). Results The mean age of patients was 57 years with a male:female ratio of 1. No retinopathy was found in 556 (61.5%) patients. In all, 175 (19.4%) patients had features of hypertensive retinopathy. Retinal vascular occlusion was a significant finding in 121 patients (13.4%), of which branch retinal vein occlusion, 43 (4.7%), and central retinal vein occlusion, 30 (3.3%), were the most prominent ones in cases. Hemicentral retinal vein occlusion, 26 (2.9%), and central retinal artery occlusion, 17 (1.9%), were significant presentations. Other findings included nonarteritic anterior ischemic optic neuropathy in five (0.6%) patients, hypertensive choroidopathy in seven (0.8%) patients, and hemorrhagic choroidal detachment in five (0.6%) patients. Left ventricular (LV) geometry was abnormal in 85 (55.5%) patients. Concentric remodeling, eccentric hypertrophy, and concentric hypertrophy were observed in 43 (27.6%), 26 (17.2%), and 15 (9.7%) patients, respectively. LV hypertrophy was found in 42 (27%) patients, while 60 (39%) patients had increased relative wall thickness. In this study, bivariate analysis showed a correlation between LV relative wall thickness and severity of retinopathy in both eyes

    Hypertension is responsible for a relevant burden of cardiovascular morbidity and mortality worldwide. Although several appropriate and integrated pharmacological strategies are available, blood pressure control still remains largely unsatisfactory. Failure to achieve effective blood pressure control in treated hypertensive patients may have a substantial impact on overall cardiovascular risk, since it significantly increases the risk of both macrovascular and microvascular complications. Hypertension is arbitrarily defined as "resistant" or "refractory" when recommended blood pressure goals (clinic blood pressure <140/90 mmHg, or <130/80 mmHg in patients with type 2 diabetes mellitus) are not achieved, despite changes in lifestyle and treatment with adequate doses of at least three antihypertensive drugs from different classes, including a diuretic. A new non-pharmacological option for the treatment of patients with resistant hypertension has recently become available. Renal sympathetic denervation is a minimally invasive procedure performed via femoral access that uses radiofrequency catheter ablation to disable renal sympathetic afferent and efferent nerves. It results in isolation of renal parenchymal and juxtaglomerular cells from the abnormal enhancement of renal adrenergic nerve activity. The present position paper of the Italian Society of Hypertension provides a diagnostic and therapeutic approach to the early identification and effective clinical management of patients with resistant hypertension, who may be candidates for renal denervation. These indications may have important implications not only from a clinical viewpoint but also from an economic perspective. The accurate identification of patients with resistant hypertension and the appropriate selection of patients eligible for this procedure may help improve blood pressure control and reduce the risk of cardiovascular and cerebrovascular complications in these patients.

    Background: Lead is a metal with many important industrial uses. The relationship between lead exposure and the rise of blood pressure has received a great deal of attention as it was implicated that the mortality from cardiovascular diseases might be reduced by lowering lead levels in the environment. Objectives: The study was to investigate the correlation between the blood lead (B-Pb) levels and the values of blood pressure in hypertensive patients. Moreover, the plasma activities of angiotensin converting enzyme (ACE), plasma levels of nitric oxide (NO), total antioxidants (TAOX) and malondialdehyde (MDA) were estimated to investigate the correlations between the measured parameters and B-Pb levels in hypertensive patients. Methods: Fifty-five hypertensive patients were compared with fifty-three age and sex matched control group. The B-Pb levels were detected by flame atomic absorption spectrometry. The plasma levels of ACE activities, NO, TAOX and MDA were measured by colorimetric methods. Results: In the hypertensive patients, B-Pb levels were significantly higher than controls. Concomitantly, the plasma levels of ACE activities and MDA were significantly increased while the plasma levels of NO and TAOX were significantly reduced in the hypertensive patients in comparison with controls. There were significant positive correlations between B-Pb and each of MDA, and systolic as well as diastolic blood pressure. Conversely, a significant negative correlation was found between B-Pb and NO. Conclusions: Our study indicated that a positive relationship exists between blood pressure and B-Pb levels. The increased B-Pb levels were associated with oxidative stress. Moreover, The B-Pb level was negatively correlated with NO and this may clarify the implication of Pb as leading risk factor for the cardiovascular diseases and hypertension. These findings provide support for continued efforts to reduce lead concentration in the population at Qassim region. PMID:22489226

    ABSTRACT Purpose: Glaucomatous neuropathy can be a consequence of insufficient blood supply, increase in intraocular pressure (IOP), or other risk factors that diminish the ocular blood flow. To determine the ocular perfusion pressure (OPP) in normal and systemic hypertensive patients. Materials and methods: One hundred and twenty-one patients were enrolled in this prospective and comparative study and underwent a complete ophthalmologic examination including slit lamp examination, Goldmann applanation tonometry, stereoscopic fundus examination, and pulsatile ocular blood flow (POBF) measurements. The OPP was calculated as being the medium systemic arterial pressure (MAP) less the IOP. Only right eye values were considered for calculations using Student’s t-test. Results: The mean age of the patients was 57.5 years (36-78), and 68.5% were women. There was a statistically significant difference in the OPP of the normal and systemic hypertensive patients (p < 0.05). The difference in the OPP between these groups varied between 8.84 and 17.9 mm Hg. Conclusion: The results of this study suggest that although the systemic hypertensive patients have a higher OPP in comparison to normal patients, this increase does not mean that they also have a higher OBF (as measured by POBF tonograph). This may be caused by chronic changes in the vascular network and in the blood hemodynamics in patients with systemic hypertension.

    Background Gene expression profiling of peripheral blood mononuclear cells (PBMCs) is a powerful tool for the identification of surrogate markers involved in disease processes. The hypothesis tested in this study was that chronic exposure of PBMCs to a hypertensive environment in remodeled pulmonary vessels would be reflected by specific transcriptional changes in these cells. Methodology/Principal Findings The transcript profiles of PBMCs from 30 idiopathic pulmonary arterial hypertension patients (IPAH), 19 patients with systemic sclerosis without pulmonary hypertension (SSc), 42 scleroderma-associated pulmonary arterial hypertensio patients (SSc-PAH), and 8 patients with SSc complicated by interstitial lung disease and pulmonary hypertension (SSc-PH-ILD) were compared to the gene expression profiles of PBMCs from 41 healthy individuals. Multiple gene expression signatures were identified which could distinguish various disease groups from controls. One of these signatures, specific for erythrocyte maturation, is enriched specifically in patients with PH. This association was validated in multiple published datasets. The erythropoiesis signature was strongly correlated with hemodynamic measures of increasing disease severity in IPAH patients. No significant correlation of the same type was noted for SSc-PAH patients, this despite a clear signature enrichment within this group overall. These findings suggest an association of the erythropoiesis signature in PBMCs from patients with PH with a variable presentation among different subtypes of disease. Conclusions/Significance In PH, the expansion of immature red blood cell precursors may constitute a response to the increasingly hypoxic conditions prevalent in this syndrome. A correlation of this erythrocyte signature with more severe hypertension cases may provide an important biomarker of disease progression. PMID:22545094

    The prevalence and long-term trends of isolated systolic hypertension (ISH) among untreated adults have not been reported. Data from 24,653 participants aged ≥18 years were selected from the National Health and Nutrition Examination Survey 1999-2010. The prevalence and 95% confidence intervals (CIs) of untreated ISH were estimated by conducting the independent survey t-test. The prevalence of untreated ISH was 9.4% and decreased from 10.3% in 1999-2004 to 8.5% in 2005-2010 (P = .00248). Old persons, females, and non-Hispanic blacks had higher prevalence of untreated ISH. Compared with 1999-2004, the prevalence of untreated ISH in 2005-2010 decreased among older (33.6%; 95% CI, 30.9%-36.3% vs. 25.1%; 95% CI, 22.7%-27.5%) and female individuals (8.3%; 95% CI, 7.5-9.2% vs. 11.4%; 95% CI, 10.4-12.3%). The stratified prevalence of untreated ISH declined in 2005-2010 (vs. 1999-2004) for older non-Hispanic whites (24.6% vs. 32.8%; P < .0001) and blacks (27.7% vs. 40.8%; P = .0013), non-Hispanic white females (7.5% vs. 10.8%; P < .0001), older individuals with higher education (21.0% vs. 30.6%; P = .0024), and females with lower education (10.1% vs. 13.1%; P = .006). Untreated ISH is more prevalent in older adults and females. Significant decreases in untreated ISH prevalence over time among these groups suggest that public health measures and/or treatment patterns are trending in the right direction. PMID:25795550

    We studied the combined treatment effects of quinapril and atorvastatin on blood pressure and structure and function of resistance arteries from adult spontaneously hypertensive rats (SHR) and normotensive Wistar-Kyoto rats (WKY rats). Apoptotic cells were identified by in situ end labeling using the terminal deoxynucleotide transferase-mediated dUTP nick end labeling method. Vascular structure was measured using a morphometric protocol and confocal microscopy and a pressurized artery system was used to study vascular functions. We found that a combined treatment with quinapril and atorvastatin lowered systolic blood pressure in both adult SHR and WKY rats and decreased medial thickness and volume and the number of smooth muscle cell layers in mesenteric arteries, as well as media-to-lumen ratio in the interlobular arteries from SHR but not in those from WKY rats. The number of apoptotic smooth muscle cells was higher in the mesenteric arteries from control WKY rats than control SHR and treatment increased the number of apoptotic smooth muscle cells in the arteries from both SHR and WKY rats. Treatment with quinapril and atorvastatin reduced ventricular weight in SHR and normalized the augmented contractile responses to norepinephrine but did not alter the contraction to electric field stimulation. Relaxation responses to acetylcholine and sodium nitroprusside were not affected by the treatment. We conclude that a combined treatment with quinapril and atorvastatin lowered blood pressure and improved cardiac and vessel hypertrophy and vessel function. An increase in apoptotic smooth muscle cells may be one of the mechanisms underlying the structural improvement.

    Male adult spontaneously hypertensive rats (SHR) ate the same but drank more and had a higher water to food ratio (W:F) than did Wistar-Kyoto (WKY) rats in 24-hr when they had continuous access to standard laboratory pellets and tap water. When rats ate in the day phase of a 12:12 light/dark cycle after 24-hr food deprivation, SHR rats ate and drank the same ad did WKY rats in a 60-min test. When the same rats ate at night after 24-hr food deprivation, however, SHR rats were hyperdipsic: They ate the same as did WKY rats, but SHR rats drank more and had a higher W:F. This relative hyperdipsia reflected the increased ability of ingestion of food to stimulate drinking in SHR, because when food was absent for a 60-min test at night SHR drank the same as did WKY rats. Three dipsogens which are candidate components for eating-elicited drinking in the rat, cellular dehydration, histamine and angiotensin II, elicited drinking differentially in SHR and WKY rats: SHR drank more than did WKY rats in response to (1) cellular dehydration produced by IP hypertonic saline, (2) large doses of SC histamine, and (3) SC angiotensin II. These results demonstrate that SHR exhibit a nocturnal food-related hyperdipsia which may reflect differential sensitivity to stimuli important for eating-elicited drinking such as increased osmolality and endogenous histamine or angiotensin.

    High parathyroid hormone (PTH) has been linked with high blood pressure (BP), but the relationship with 24-hour ambulatory blood pressure monitoring is largely unknown. The authors therefore analyzed cross-sectional data of 292 hypertensive patients participating in the Styrian Hypertension Study (mean age, 61±11 years; 53% women). Median plasma PTH (interquartile range) determined after an overnight fast was 49 pg/mL (39-61), mean daytime BP was 131/80±12/9 mm Hg, and mean nocturnal BP was 115/67±14/9 mm Hg. In multivariate regression analyses adjusted for BP and PTH-modifying parameters, PTH was significantly related to nocturnal systolic and diastolic BP (adjusted β-coefficient 0.140 [P=.03] and 0.175 [P<.01], respectively). PTH was not correlated with daytime BP readings. These data suggest a direct interrelationship between PTH and nocturnal BP regulation. Whether lowering high PTH concentrations reduces the burden of high nocturnal BP remains to be shown in future studies. PMID:26456544

    The authors propose an original program of learning in the school of a hypertensive patient (SHP) which includes 12 sixty-minute lessons devoted to causes of the disease, cardiovascular complications, methods of their prevention at treatment, and rehabilitation. The analysis of the results of 2-year follow-up showed that most of the learners became informed about the risks of hypertension, better followed recommendations of their doctor, improved their life quality. The number of hypertensive crises and urgent hospitalizations decreased significantly. In the control group of 112 patients no improvement was seen in the level of blood pressure, quality of life and prognosis. Moreover, learning in the SHP proved highly cost-effective.

    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.

    Introduction: It is known that pulmonary hypertension is associated with worse outcome in both cardiac and non-cardiac surgery. The aims of our retrospective analysis were to evaluate the outcomes of our patients with pulmonary hypertension undergoing major orthopedic surgery and to give experience-based recommendations for the perioperative management. Material and methods: From 92 patients with pulmonary hypertension undergoing different kinds of surgical procedures from 2011–2014 in a tertiary academic hospital we evaluated 16 patients with major orthopedic surgery for perioperative morbidity and mortality. Results: Regarding the in-hospital morbidity and mortality, one patient died postoperatively due to pulmonary infection and right heart failure (6.25%) and 6 patients suffered significant postoperative complications (37.5%; bleeding = 1, infection = 1, wound healing deficits = 3; dysrhythmia = 1). Conclusion: Our data show that major orthopedic surgery is feasible with satisfactory outcome even in cases of severe pulmonary hypertension by an individualized, disease-adapted interdisciplinary treatment concept.

    In previous studies, we established a strong concordance between nocturnal oscillations in plasma renin activity (PRA) and REM-NREM sleep cycles. To determine whether this relation persists in the case of moderate essential hypertension and if it is influenced by antihypertensive therapies affecting renin release, six normal subjects and six hypertensive patients were studied. The normal subjects underwent one control night. The hypertensive patients were studied during a first night when a placebo was given. Four of them underwent a second night following a single dose of an angiotensin-converting enzyme (ACE) inhibitor, perindopril; and a third night, 45 days later, with the antihypertensive treatment. In addition, two of the patients underwent two night-studies, after a single and repeated doses of a beta-blocker, atenolol, to see whether preventing renin release modified the sleep structure. The relationship between the nocturnal PRA oscillations and the sleep stage patterns persisted in hypertensive patients receiving placebo. In patients who had low PRA levels, the increases associated with NREM sleep were small. However, the mean relative amplitude of the oscillations, expressed as a percentage of the nocturnal mean, was about 60%, which was similar to that in normotensive subjects. Active renin and PRA oscillations were closely coupled. ACE activity profiles displayed damped fluctuations and no systematic relationship with sleep stages.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2172356

    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.

    Background. Since the treatment of hypertension is beneficial for the elderly, we have undertaken this study that aims to evaluate the management of hypertension in elderly patient in Côte d'Ivoire. Methods. A retrospective study was conducted among 854 hypertensive elderly patients of Abidjan Cardiology Institute who were followed for a minimum of one year, between January 2000 and December 2009. Results. The patients mean age was 73.1 ± 5.3 years, and 59% were women. At the first presentation, it was mostly systolic-diastolic hypertension (51.8%) and isolated systolic hypertension (38.5%). Mean blood pressure was 169.4 ± 28.4 mmHg for systolic, 95.3 ± 15.7 mmHg for diastolic, and 74.1 ± 22.8 mmHg for pulse pressure. Pulse pressure was ≥60 mmHg in 80.4%. According to the European Guidelines stratification of the cardiovascular risk-excess attributable to high blood pressure, 82.1% of the sample had a very high added risk. The pharmacological therapy was prescribed in 93.5%. More than 66% of patients were receiving ≥2 antihypertensive drugs including fixed-dose combination drugs. The most common agents used were diuretics (63.5%) followed by angiotensin-converting enzyme inhibitors or angiotensin receptor blockers in 61.3%. The most common agents used for monotherapy were calcium antagonists. When ≥2 drugs were used, diuretics and angiotensin-converting enzyme inhibitors or angiotensin receptor blockers were the most common. Blood pressure control was achieved in 42.6%. Conclusion. The control of elderly hypertension can be effective in Sub-Saharan Africa. He required at least two antihypertensive drugs to meet the recommended blood pressure target. PMID:22028955

    Growth differentiation factor 15 (GDF-15) is a relatively new biomarker that predicts adverse stroke outcomes. However, the association of GDF-15 with first-ever stroke in hypertensive patients has not yet been evaluated. The objective of this study was to evaluate the clinical implications of plasma GDF-15 on the development of first-ever stroke in patients with hypertension.In total, 254 patients with hypertension without a history of stroke were included from March 2010 to August 2010 and followed up until June 2013. The baseline circulating GDF-15 was determined by enzyme-linked immunosorbent assays.During a follow-up of 3.0 ± 0.6 years, 22 (8.7%) first-ever strokes were identified, including 12 ischemic strokes and 10 intracerebral hemorrhages (ICH). According to tertiles of GDF-15, survival free of first-ever stroke was lower in the highest tertile of GDF-15 (log-rank P = 0.001). By backward stepwise Cox-regression analysis, adjusted for age, gender, diabetes mellitus, hyperlipidemia, hypertension stage, body mass index, cigarette smoking, anti-hypertensive drugs, and uric acid, every 100 pg/mL-increase in plasma of GDF-15 predicted an 11% greater risk of first-ever stroke (hazard ratios [HR]: 1.11, 95% confidence interval [CI]: 1.03-1.20, P = 0.010) and an 18% increase in ischemic stroke risk (HR: 1.18, 95% CI: 1.07-1.30, P = 0.001). Receiver operating characteristic analysis indicated that GDF-15 had reasonable accuracy to predict first-ever stroke (area under curve = 0.73, 95% CI: 0.62-0.83, P < 0.001).This study identifies that GDF-15 is an independent predictor of first-ever stroke, especially for ischemic stroke in the patients with hypertension.

    The objective of the present study was to define the risk factors for hypertension and to analyze the influence of insertion/deletion (I/D) polymorphism of the angiotensin-converting enzyme (ACE) on hypertension in pediatric renal transplant recipients. Twenty-six pediatric renal transplant recipients with stable renal function and treated with the same immunosuppression protocol were included in the study. Their mean age was 12.5 +/- 3.3 yr and mean time after transplantation was 38.5 +/- 39.8 month. Twenty-four hour ambulatory blood pressure monitoring (ABPM) was performed by SpaceLabs (90207) device. The I/D polymorphism of the ACE was determined by PCR and ACE serum level was analyzed by colorimetric method. Hypertension was present in 15 patients (57.7%) by causal blood pressure measurements and 19 patients (73.1%) by ABPM. Twenty-two patients (84.6%) were found to be non-dipper and eight of them had reverse dipping. Only time after transplantation (38 +/- 31 vs. 79 +/-49 month, p = 0.016) and cyclosporin A trough plasma levels (206 +/-78 vs. 119 +/- 83 ng/mL, p = 0.020) influenced the presence of hypertension by multiple logistic regression analysis. The distribution of genotypes were II = 2 (7.7%), ID = 8 (30.8%), DD = 16 (61.5%). There was no effect of ACE gene I/D polymorphism or serum ACE levels on hypertension prevalence and circadian variability of blood pressures. Hypertension was related to the time after transplantation and cyclosporin A levels. The ACE gene I/D polymorphism and serum ACE levels did not influence the blood pressure values or circadian variability of blood pressure among pediatric renal transplant patients. PMID:16176418

    Ambulatory blood pressure (BP) monitoring has become useful in the diagnosis and management of hypertensive individuals. In addition to 24-hour values, the circadian variation of BP adds prognostic significance in predicting cardiovascular outcome. However, the magnitude of circadian BP patterns in large studies has hardly been noticed. Our aims were to determine the prevalence of circadian BP patterns and to assess clinical conditions associated with the nondipping status in groups of both treated and untreated hypertensive subjects, studied separately. Clinical data and 24-hour ambulatory BP monitoring were obtained from 42,947 hypertensive patients included in the Spanish Society of Hypertension Ambulatory Blood Pressure Monitoring Registry. They were 8384 previously untreated and 34,563 treated hypertensives. Twenty-four-hour ambulatory BP monitoring was performed with an oscillometric device (SpaceLabs 90207). A nondipping pattern was defined when nocturnal systolic BP dip was <10% of daytime systolic BP. The prevalence of nondipping was 41% in the untreated group and 53% in treated patients. In both groups, advanced age, obesity, diabetes mellitus, and overt cardiovascular or renal disease were associated with a blunted nocturnal BP decline (P<0.001). In treated patients, nondipping was associated with the use of a higher number of antihypertensive drugs but not with the time of the day at which antihypertensive drugs were administered. In conclusion, a blunted nocturnal BP dip (the nondipping pattern) is common in hypertensive patients. A clinical pattern of high cardiovascular risk is associated with nondipping, suggesting that the blunted nocturnal BP dip may be merely a marker of high cardiovascular risk. PMID:19171788

    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.

    Achieving and maintaining a healthy lifestyle is an important part of hypertension management. The purpose of this study was to assess US state-level prevalence of adherence to healthy lifestyle behaviors among those with self-reported hypertension. Using 2013 data from the Behavioral Risk Factor Surveillance System, a state-based telephone survey, we examined the adherence to five healthy lifestyle behaviors related to hypertension management: having a "normal" weight, not smoking, avoiding or limiting alcohol intake, consuming the recommended amount of fruits and vegetables, and engaging in the recommended amount of physical activity. We estimated age-standardized percentages of each healthy lifestyle behavior overall and by state, as well as prevalence of all five healthy lifestyle behaviors. Overall, the prevalence of healthy lifestyle behaviors varied widely among those with self-reported hypertension: 20.5% had a normal weight, 82.3% did not smoke, 94.1% reported no or limited alcohol intake, 14.1% consumed the recommended amounts of fruits or vegetables, and 46.6% engaged in the recommended amount of physical activity. Overall, only 1.7% of adults with self-reported hypertension reported all five healthy lifestyle behaviors, with significant variation by state. Age-standardized prevalence of individuals reporting all five healthy lifestyle behaviors ranged from 0.3% in Louisiana to 3.8% in the District of Columbia. In conclusion, adherence to healthy lifestyle behaviors varied among those with hypertension; fewer than 2% reported meeting current recommendations and standards when assessed collectively. Disparities were observed by demographic and descriptive characteristics, including geography. PMID:26851000

    Inevitably, a small proportion of patients with systematic hypertension will develop hypertensive crisis at some point. Hypertensive crises can be divided into hypertensive emergency or hypertensive urgency according to the presence or lack of acute target organ damage. In this review, we discuss cardiovascular hypertensive emergencies, including acute coronary syndrome, aortic dissection, congestive heart failure, and sympathomimetic hypertensive crises, including those caused by cocaine use. Each presents in a unique fashion, although some hypertensive emergency patients report nonspecific symptoms. Treatment includes several effective and rapid-acting medications to safely reduce the blood pressure, protect remaining end-organ function, relieve symptoms, minimize the risk of complications, and thereby improve patient outcomes.

    Variability in daily blood pressure (BPV) recorded 24-h ambulatory blood pressure monitoring (ABPM) is known to be related to left ventricular hypertrophy and an increased incidence of cardiovascular events in hypertensive patients. The aim of this study was to evaluate whether left atrium dimension, which increases early in hypertensive subjects, was related to BPV in a group of 167 drug-naive patients (100M/67F, age: 46±11yr). The patients were chosen among those consecutively sent by their general practitioners to confirm the existence of arterial hypertension and afterwards diagnosed as hypertensive (mean 24-h ABPM ⩾130/80 mm Hg). In each patient, the left atrial posteroanterior diameter index for height (LADi) and the left ventricular mass standardized for body surface area (LVMi) were measured using standardized echocardiographic methods. BPV was calculated as the weighted mean of daytime and nighttime systolic and diastolic blood pressure s.d.'s (ws.d.), according to the formula ws.d.=[(daytime s.d. × 10)+nighttime s.d. × 6)]/16. An increase in left atrial dimension (LADi>24 mm m(-1)) was present in 36 patients (21.6% of the total population). In a univariate regression, LVMi was significantly related to systolic BPV (r=0.24; P=0.02) only in men, whereas LADi was significantly related to both systolic and diastolic BPV in both genders. After adjusting for sex, age, BMI, heart rate, diastolic function and estimated glomerular filtration rate, both systolic and diastolic BPV remained significantly related to LADi (P=0.02 for both) but not to LVMi. In conclusion, this study suggests that BVP, as measured as BPws.d., is significantly and independently associated with increased LADi in newly diagnosed, treatment-naive hypertensive patients.

  14. Utility of home blood pressure monitoring to evaluate postprandial blood pressure in treated hypertensive patients.

    2015-08-01

    Postprandial hypotension, defined as a fall in systolic blood pressure (SBP) of 20 mmHg or greater within 2 hours after a meal, is a risk factor for stroke, coronary events and mortality. The clinical suspicion is typically raised by episodes of postprandial syncope or falls, whereas asymptomatic postprandial hypotension is mostly neglected. The magnitude of the postprandial fall in SBP, as detected by 24-hour recording in apparently healthy middle-aged to elderly subjects, was proportional to the severity of the silent cerebrovascular damage. Postprandial hypotension can also be detected by self-measured blood pressure before and within 2 hours after meals using automatic devices. The review highlights the value of home blood pressure monitoring (HBPM) as a screening test for asymptomatic postprandial hypotension in hypertensive patients. Using a HBPM protocol that included duplicated blood pressure measurements before and after three consecutive lunches, we detected unsuspected postprandial hypotension in 27.4% of the 230 hypertensive patients screened. The prevalence of postprandial hypotension was 13.2% in controlled and 42.2% in uncontrolled hypertensive patients (p < 0.001), raising the dilemma of further lowering blood pressure in the setting of postprandial hypotension. The inclusion of preprandial and postprandial measurements in the protocol of HBPM is useful to identify hypertensive patients with postprandial hypotension and may guide adjustments in antihypertensive treatment according to postprandial blood pressure.

    Posterior reversible encephalopathy syndrome (PRES) is a clinical and neuroimaging entity characterized by headache, visual field deficits, changes in mentation and seizures, and by typical neuro-imaging features such as areas of sub-cortical edema, occasionally cortical, involving predominantly the occipital and parietal lobes of both hemispheres. Hypertension, uremia, immunosuppressive drugs neurotoxicity, preeclampsia or eclampsia, renal disease, and sepsis are the most common etiologies of PRES. Less common, it has been described in the setting of autoimmune disease. We report a case of PRES which was associated with hypertensive crisis in a patient with renal failure. Antihypertensive therapy and hemodialysis resulted in complete recovery.

    Purpose: Patients with diastolic dysfunction may have a disproportionate degree of elevation in pulmonary pressure, particularly in the elderly. Higher pulmonary vascular resistance in the elderly patients with heart failure but preserved ejection fraction suggests that beyond the post-capillary contribution of pulmonary venous congestion, a pre-capillary component of pulmonary arterial hypertension occurs. We aim to identify if pulmonary vascular resistance in elderly patients with diastolic dysfunction is disproportionately higher than patients with systolic dysfunction independent of filling pressures. Methods: 389 patients identified retrospectively between 2003- 2010; elderly with preserved ejection fraction, elderly with depressed ejection fraction, and primary arterial hypertension who underwent right-heart catheterization at Rush University. Results: No significant difference in pulmonary vascular resistance between systolic and diastolic dysfunction. The mean difference in pulmonary vascular resistance was not statistically significant at 0.40 mmHg·min/l (95% CI -3.03 to 3.83) with similar left ventricular filling pressures with mean difference of 3.38 mmHg (95% CI, -1.27 to 8.02). When adjusted for filling pressures, there remained no difference in pulmonary vascular resistance for systolic and diastolic dysfunction. The mean pulmonary vascular resistance is more elevated in systolic heart failure compared to diastolic heart failure with means 3.13 mmHg·min/l and 3.52 mmHg·min/l, respectively. Conclusion: There was no other association identified for secondary pulmonary hypertension other than diastolic dysfunction and chronic venous pulmonary hypertension. Our results argue against any significant arterial remodeling that would lead to disproportionate pre-capillary hypertension, and implies that treatment should focus on lowering filling pressure rather than treating the pulmonary vascular tree.

    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

    Pharmacological treatment of hypertension represents a cost-effective way of preventing cardiovascular and renal complications. To benefit maximally from antihypertensive treatment, blood pressure should be brought to below 140/90 mmHg in every hypertensive patient, and even lower (< 130/80 mmHg) if diabetes or renal disease co-exists. Such targets cannot usually be reached using monotherapies. This is especially true in patients who present with a high cardiovascular risk. The co-administration of two agents acting by different mechanisms considerably increases the blood pressure control rate. Such combinations are not only efficacious, but are also well tolerated, and some fixed low-dose combinations even have a placebo-like tolerability. This is the case for the preparation containing the angiotensin-converting enzyme inhibitor perindopril (2 mg) and the diuretic indapamide (0.625 mg), a fixed low-dose combination that has been shown in controlled trials to be more effective than monotherapies in reducing albuminuria, regressing cardiac hypertrophy and improving the stiffness of large arteries. Using this combination to initiate antihypertensive therapy has been shown in a double-blind trial (Strategies of Treatment in Hypertension: Evaluation; STRATHE) to normalize blood pressure (< 140/90 mmHg) in significantly more patients (62%) than a sequential monotherapy approach based on atenolol, losartan and amlodipine (49%) and a stepped-care strategy based on valsartan and hydrochlorothiazide (47%), with no difference between the three arm groups in terms of tolerability. An ongoing randomized trial (Action in Diabetes and Vascular Disease: Preterax and Diamicron Modified Release Controlled Evaluation; ADVANCE) is a study with a 2 x 2 factorial design assessing the effects of the fixed-dose perindopril-indapamide combination and of the intensive gliclazide modified release-based glucose control regimen in type 2 diabetic patients, with or without hypertension.

    Portopulmonary hypertension (PPHTN) is a rare complication in patients with portal hypertension. A role of endothelin 1 (ET-1) and other cytokines was demonstrated in primary pulmonary hypertension but not in PPHTN. We evaluated the possible role of ET-1, interleukin 6 (IL-6), interleukin 1β (IL-1β), and tumor necrosis factor alpha (TNF-α) in the pathogenesis of PPHTN. Plasmatic concentrations of ET-1, IL-6, IL-1β, and TNF-α were measured in patients with pulmonary systolic arterial pressure (PAPs) >30 mm Hg and in patients with cirrhosis. In all, Six out of 11 patients with PAPs >30 mm Hg had PPHTN on right heart catheterization. The remaining 10 patients had an hyperdynamic circulation (HC). In PPHTN patients, ET-1 and IL-6 were significantly higher compared with HC and patients with cirrhosis. Endothelin 1 and IL-6 could be implicated in the pathogenesis of PPHTN. On the basis of these results, ET-1 receptor antagonists or anti-IL-6 could have a rationale in the treatment of PPHTN.

    Hypertension is a well-known health problem all over the world. Many studies have assessed its prevalence and associated risk factors, but all were cross-sectional and did not evaluate the trend of hypertension through all three different temporal dimensions including age, period, and cohort. So, we aimed to assess the 20-year dynamics of hypertension via the age-period-cohort model. Data from 74,155 subjects aged 25-60 years gathered through five national health surveys (1990-91, 1999, 2003, 2007, and 2011) were used in this study. The age-period-cohort effect on hypertension was analyzed using the intrinsic estimator model. The prevalence of hypertension increased with age for both genders except for males in 2003 and 2011 periods with drops of 3.5% for ages 55-60 and 8.1% for ages 50-60, respectively. As for the period effect, the prevalence of hypertension was almost constant in all age groups for both genders from 1990-1999. The cohort-based prevalence of hypertension showed a declining trend in all cohorts for females except for 2011 in birth cohort of 1950-1955 which remains stationary. The trend of prevalence for males also follows a decreasing trend except for periods of 2003, 2007, and 2011; birth cohorts of 1945-1949, 1975-1980, and 1950-1960 increase by 3.5%, 1.9%, and 8.1%, respectively. The age effect on the prevalence of hypertension showed an almost monotonic increasing trend. The period effect increased the total prevalence of hypertension from 1992 to 1997. The cohort effect also showed a monotonic decrease in hypertension prevalence except for a few discrepancies. PMID:26481410

In memory of a great contribution to hypertensiology by the late Prof. Murakami, who was the first author to write on pheochromocytoma in Japan, this paper is dedicated to reviewing the current status of adrenal hypertension in Japan from the epidemiological viewpoint, putting emphasis upon the clinical characteristics of aged patients with adrenal hypertension. Secondly, some topics in the research field of each adrenal hypertension are briefly introduced. Thirdly, our recent data are presented, showing 11 beta-hydroxysteroid dehydrogenase (11 beta-HSD) mRNA expression in resistance vessels and decreased 11 beta-HSD activities in vessels in SHR which supports the hypothesis that there might exist a subtype identified as partial impairment of 11 beta-HSD in patients with essential hypertension.

    Persons aged over 65 years account for over 75% of healthcare expenditures and deaths attributable to cardiovascular disease (CVD). Accordingly, reducing CVD risk among older adults is an important public health priority. Functional status, determined by measures of physical performance, is an important predictor of cardiovascular outcomes in older adults and declines more rapidly in seniors with hypertension. To date, physical exercise is the primary strategy for attenuating declines in functional status. Yet despite the general benefits of training, exercise alone appears to be insufficient for preventing this decline. Thus, alternative or adjuvant strategies are needed to preserve functional status among seniors with hypertension. Prior data suggest that angiotensin converting enzyme inhibitors (ACEi) may be efficacious in enhancing exercise-derived improvements in functional status yet this hypothesis has not been tested in a randomized controlled trial. The objective of this randomized, double-masked pilot trial is to gather preliminary efficacy and safety data necessary for conducting a full-scale trial to test this hypothesis. Sedentary men and women ≥ 65 years of age with functional limitations and hypertension are being recruited into this 24 week intervention study. Participants are randomly assigned to one of three conditions: (1) ACEi plus exercise training, (2) thiazide diuretic plus exercise training, or (3) AT1 receptor antagonist plus exercise training. The primary outcome is change in walking speed and secondary outcomes consist of other indices of CV risk including exercise capacity, body composition, as well as circulating indices of metabolism, inflammation and oxidative stress.

    OBJECTIVES: To evaluate the prevalence of hypertension, the average blood pressure level, the 24 h blood pressure profile, and the efficacy of antihypertensive therapy for a large population of peritoneal dialysis patients.DESIGN: A cross-sectional, observational multicenter study. METHODS: From 504 peritoneal dialysis patients (18% of the Italian peritoneal dialysis population) involved in a multicenter observational study, we selected 414 who had undergone successful ambulatory blood pressure monitoring (i.e. no hours with data absent, >/= 75% successful readings and monitoring duration >/= 24 h). Office blood pressure measurements and ambulatory blood pressure monitoring were performed for each patient on the same day with a standard mercury sphygmomanometer and a SpaceLabs 90207 device, respectively.RESULTS: According to World Health Organization/International Society of Hypertension criteria, 44 peritoneal dialysis patients (10.6%) were normotensive and 370 patients (89.4%) were hypertensive, 304 (82.1%) of whom were being administered antihypertensive therapy. Daytime systolic and diastolic blood pressures were both significantly lower than office systolic and diastolic blood pressures (140.7 +/- 19.7/72.1 +/-11.1 versus 148.3 +/- 23.6/85.6 +/- 12 mmHg; P < 0.001). The difference between office blood pressure and daytime blood pressure was significantly correlated to office blood pressure (P < 0.001 for systolic and P < 0.001 for diastolic). The diurnal blood pressure rhythm evaluated by visual inspection of hourly mean plots was not influenced by sex, age, antihypertensive treatment, and peritoneal dialysis modality. Systolic and diastolic blood pressures exhibited a day-night mean decreases of 8.6 +/- 11.7 and 7.7 +/- 6.9 mmHg, respectively, and daytime blood pressure values were significantly higher than night-time ones (P < 0.001). Two hundred and twenty patients (53.1%) were nondippers according to O'Brien's criteria, 247 patients (59.7%) were nondippers

    Development of direct-acting antiviral agents against hepatitis C virus (HCV) has changed the management of chronic HCV infection. We report three cases of newly diagnosed or exacerbated pulmonary arterial hypertension (PAH) in patients treated with sofosbuvir. All patients had PAH-associated comorbidities (HIV coinfection in two, portal hypertension in one) and one was already being treated for PAH. At admission, all patients presented with syncope, World Health Organization functional class IV, right-sided heart failure, and extremely severe hemodynamic parameters. After specific PAH therapy, the clinical and hemodynamic properties for all patients were improved. Severity and acuteness of PAH, as well as chronology, could suggest a causal link between HCV treatment and PAH onset. We hypothesize that suppression of HCV replication promotes a decrease in vasodilatory inflammatory mediators leading to worsening of underlying PAH. The current report suggests that sofosbuvir-based therapy may be associated with severe PAH.

    Prostaglandin E1. (Prostavasin, Schwarz, FRG) was administered in a short-term infusion, 5-30 ng/kg/min., to five patients with precapillary pulmonary hypertension associated with lung disease. Significant pulmonary vasodilatation characterized by a drop of the median pressure in the pulmonary artery by 15% and of the pulmonary vascular resistance by 31% was achieved only in two patients. The authors observed a minimal incidence of side-effects; systemic hypotension observed in three patients was an undesirable manifestaútion. Prostaglandin E1 extends possibilities of a vasodilatating influence on precapillary pulmonary hypertension in lung disease. With regard to the different individual reactivity of patients it should be administered in this indication only under conditions of haemodynamic monitoring.

    Glaucoma is a potentially blinding disease that affects millions of people worldwide. The mainstay of treatment is lowering of intraocular pressure (IOP) through the use of medications, laser and/or incisional surgery. The trabecular meshwork (TM) is thought to be the site of significant resistance to aqueous outflow in open angle glaucoma. Theoretically, an incision through TM or TM removal should decrease this resistance and lead to a significant reduction in IOP. This approach, commonly referred to as goniotomy or trabeculotomy, has been validated in the pediatric population and has been associated with long-term IOP control. In adults, however, removal of TM tissue has been historically associated with more limited and short-lived success. More recent evidence, reveals that even adult patients may benefit significantly from removal of diseased TM tissue and can lead to a significant reduction in IOP that is long-lasting and safe. In this review, we discuss current evidence and techniques for ab interno trabeculectomy using various devices in the adult patient. PMID:25624670

    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

    Resistant hypertension is a severe medical condition which is estimated to appear in 9-18% of hypertensive patients. Due to higher cardiovascular risk, this disorder requires special diagnosis and treatment. The heterogeneous etiology, risk factors and comorbidities of resistant hypertension stand in need of sophisticated evaluation to confirm the diagnosis and select the best therapeutic options, which should consider lifestyle modifications as well as pharmacological and interventional treatment. After having excluded pseudohypertension, inappropriate blood pressure measurement and control as well as the white coat effect, suspicion of resistant hypertension requires an analysis of drugs which the hypertensive patient is treated with. According to one definition - ineffective treatment with 3 or more antihypertensive drugs including diuretics makes it possible to diagnose resistant hypertension. A multidrug therapy including angiotensin - converting enzyme inhibitors, angiotensin II receptor blockers, beta blockers, diuretics, long-acting calcium channel blockers and mineralocorticoid receptor antagonists has been demonstrated to be effective in resistant hypertension treatment. Nevertheless, optional, innovative therapies, e.g. a renal denervation or baroreflex activation, may create a novel pathway of blood pressure lowering procedures. The right diagnosis of this disease needs to eliminate the secondary causes of resistant hypertension e.g. obstructive sleep apnea, atherosclerosis and renal or hormonal disorders. This paper briefly summarizes the identification of the causes of resistant hypertension and therapeutic strategies, which may contribute to the proper diagnosis and an improvement of the long term management of resistant hypertension.

    The abnormal metabolism of metal ions plays an important role in health and disease conditions; hence, the studies about them have received much interest. The objective of this study was to evaluate the association between trace and toxic elements zinc (Zn), cadmium (Cd), selenium (Se), and mercury (Hg) in biological samples (scalp hair, blood, and urine) of hypertensive patients (n = 257), residents of Hyderabad, Pakistan. For comparison purpose, the biological samples of age-matched healthy controls were selected as referents. The concentrations of trace and toxic elements were measured by atomic absorption spectrophotometer prior to microwave-assisted acid digestion. The validity and accuracy of the methodology was checked using certified reference materials and by the conventional wet acid digestion method. The recovery of all studied elements was found in the range of 96.4-99.1 % in certified reference materials. The results of this study showed that the mean values of Cd and Hg were significantly higher in scalp hair, blood, and urine samples of hypertensive patients than in referents (P < 0.001), whilst the concentrations of Zn and Se were lower in the scalp hair and blood, but higher in the urine samples of hypertensive patients. The deficiency of Zn and Se and the high exposure of toxic metals may be synergistic with risk factors associated with hypertension.

    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. PMID:26902495

    Previous studies have shown that hyperoxia-induced deactivation of carotid body chemoreceptors reduces sympathetic activity in hypertensive patients but it does not affect blood pressure. The maintenance of blood pressure can be explained by the direct, vasoconstrictive effect of hyperoxia, which offsets diminished sympathetic activity. This study compares the effect of acute hyperoxia on hemodynamic parameters between hypertensive and normotensive subjects. Twelve males with hypertension (age 39.4±2.4 years; body mass index 27.4±1.1 kg m(-2)) and 11 normotensive males (age 39.9±2.7 years; body mass index 25.4±0.7 kg m(-2)) received, via non-rebreathing mask ventilation, ambient air, followed by 100% oxygen for 20 min. The stroke volume, heart rate, cardiac output, blood pressure, total peripheral resistance, respiratory rate, baroreceptor control of heart rate and oxygen saturation were recorded continuously. Several 30 s periods were analyzed before, during and after inducing hyperoxia. At baseline, the hypertensive subject's blood pressure was higher and their baroreflex control of heart rate was lower when compared with the normotensive control group. After the first 30 s of hyperoxia, systolic, diastolic and mean blood pressures, as well as the total peripheral resistance, decreased significantly in hypertensives but not in normotensives. After 20 min of 100% oxygen ventilation, systolic and mean blood pressures and total peripheral resistance was increased in hypertensive patients, and the cardiac output and stroke volume had decreased in both groups. The results of this study confirm that deactivation of carotid body chemoreceptors can acutely decrease blood pressure in humans.

    We aimed to estimate the prevalence of resistant hypertension through both office and ambulatory blood pressure monitoring in a large cohort of treated hypertensive patients from the Spanish Ambulatory Blood Pressure Monitoring Registry. In addition, we also compared clinical features of patients with true or white-coat-resistant hypertension. In December 2009, we identified 68 045 treated patients with complete information for this analysis. Among them, 8295 (12.2% of the database) had resistant hypertension (office blood pressure ≥140 and/or 90 mm Hg while being treated with ≥3 antihypertensive drugs, 1 of them being a diuretic). After ambulatory blood pressure monitoring, 62.5% of patients were classified as true resistant hypertensives, the remaining 37.5% having white-coat resistance. The former group was younger, more frequently men, with a longer duration of hypertension and a worse cardiovascular risk profile. The group included larger proportions of smokers, diabetics, target organ damage (including left ventricular hypertrophy, impaired renal function, and microalbuminuria), and documented cardiovascular disease. Moreover, true resistant hypertensives exhibited in a greater proportion a riser pattern (22% versus 18%; P<0.001). In conclusion, this study first reports the prevalence of resistant hypertension in a large cohort of patients in usual daily practice. Resistant hypertension is present in 12% of the treated hypertensive population, but among them more than one third have normal ambulatory blood pressure. A worse risk profile is associated with true resistant hypertension, but this association is weak, thus making it necessary to assess ambulatory blood pressure monitoring for a correct diagnosis and management.

    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 Resistant hypertension is a common clinical problem of blood pressure that is not controlled despite the simultaneous application of multiple antihypertensive agents. Ablation of renal afferent nerves has been applied and proved to decrease hypertension and injuries produced by severe sympathetic hyperactivity. The main objective of this study was to investigate the long-term effect of renal artery sympathetic ablation and its complications in patients with treatment-resistant hypertension. METHODS In this prospective study which done between March 2012 and November 2013, 30 patients with resistant arterial hypertension despite treatment with ≥3 antihypertensive drugs-were randomly enrolled in this self-control clinical study in Isfahan, Iran. The patients were treated with the renal denervation procedure; the femoral artery was accessed with the standard endovascular technique and the Symplicity catheter was advanced into the renal artery and connected to a radiofrequency generator. Before and 12 months after renal denervation procedure waist, body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), metabolic syndrome, fasting blood sugar (FBS), high-density lipoprotein (HDL), and triglyceride were measured in all patients. RESULTS Both mean SBP and DBP were significantly decreased, 12 months after renal denervation (P < 0.001). The frequency of metabolic syndrome was not significantly different after renal denervation in compare to baseline (P = 0.174). Furthermore, a significant decreased in FBS and triglyceride was observed in compare to baseline (P = 0.001). CONCLUSION This study highlighted the role of renal sympathetic denervation as a modern and secure catheter-based method for sustained reduction hypertension in treatment-resistant cases.

    Primary aldosteronism (PA) is a frequent cause of secondary hypertension and is amenable to surgical intervention when it is caused by aldosterone-producing adenoma (APA). Many patients, however, continue to require antihypertensive medications to control their blood pressure after adrenalectomy. The aim of this study was to determine the preoperative factors that predict clinical outcomes after adrenalectomy in patients with APA. We studied 27 patients (mean age 45±4 yr) who had APA and underwent unilateral adrenalectomy between December 1995 and September 2008 at our institution. Clinical and biochemical data were evaluated at baseline and after a mean follow-up of 51.8±47.0 months (range, 6-159). At the end of the follow-up, 16 patients (59.3%) were considered to experience "complete resolution" without postoperative medications, whereas 7 patients (25.9%) "improved" with medications and 4 patients (14.8%) were "uncontrolled." Three factors (≤2 antihypertensive medications [P=0.007], duration of hypertension <6 yr [P=0.002], and serum aldosterone <350 pg/mL [P<0.001]) were the predictive for complete resolution in univariate analysis. Multivariate regression analysis showed that serum aldosterone level (<350 pg/mL) was the single most important factor that predicted complete resolution after surgery (P<0.001). The best preoperative clinical factor that predicted resolution of postoperative hypertension after adrenalectomy is serum aldosterone level (<350 pg/mL). PMID:20592896

    Introduction Adherence to treatment and dietary restrictions is important for health outcomes of patients with chronic/end-stage kidney disease and hypertension. The relationship of adherence with nutritional and health literacy in children, adolescents, and young adults is not well understood. The current study examined the relationship of health literacy, nutrition knowledge, nutrition knowledge–behavior concordance, and medication adherence in a sample of children and young people with chronic/end-stage kidney disease and hypertension. Methods We enrolled 74 patients (aged 7–29 y) with a diagnosis of chronic/end-stage kidney disease and hypertension from the University of North Carolina Kidney Center. Participants completed instruments of nutrition literacy (Disease-Specific Nutrition Knowledge Test), health literacy (Newest Vital Sign), nutrition behavior (Nutrition Knowledge–Behavior Concordance Scale), and medication adherence (Morisky Medication Adherence Scale). Linear and binary logistic regressions were used to test the associations. Results In univariate comparisons, nutrition knowledge was significantly higher in people with adequate health literacy. Medication adherence was related to nutrition knowledge and nutrition knowledge–behavior concordance. Multivariate regression models demonstrated that knowledge of disease-specific nutrition restrictions did not significantly predict nutrition knowledge–behavior concordance scores. In logistic regression, knowledge of nutrition restrictions did not significantly predict medication adherence. Lastly, health literacy and nutrition knowledge–behavior concordance were significant predictors of medication adherence. Conclusion Nutrition knowledge and health literacy skills are positively associated. Nutrition knowledge, health literacy, and nutrition knowledge–behavior concordance are positively related to medication adherence. Future research should focus on additional factors that may predict

    Patients' knowledge concerning high blood pressure (HBP) is a useful outcome measure in HBP education programs. However, valid and easy-to-use HBP knowledge assessment tools are scarce. The purpose of the study was to validate the HBP Knowledge Test (HKT) in two independent samples of Korean Americans with HBP (N=885). A total of 61% of the sample were women with a mean age of about 61 years (standard deviation=11.0) and 44% reported some college education or greater. Psychometric and item response theory analyses identified 21 items that fit a unidimensional model to form the HKT. Internal consistency was acceptable, with Cronbach's α=0.70. Construct validity testing revealed that patients with controlled BP had significantly higher HKT scores than those with uncontrolled BP (P=.012). The HKT is a simple questionnaire for assessing and monitoring HBP knowledge. It is sensitive to differences in blood pressure control status and should provide a valid, reliable, and standardized measure of HBP knowledge with wide relevance.

    Background Despite the known health risks of hypertension, many hypertensive patients still have uncontrolled blood pressure. Clinical inertia, the tendency of physicians not to intensify treatment, is a common barrier in controlling chronic diseases. This trial is aimed at determining the impact of activating patients to ask providers to make changes to their care through tailored feedback. Methods Diagnosed hypertensive patients were enrolled in this RCT and randomized to one of two study groups: (1) the intervention condition - Web-based hypertension feedback, based on the individual patient’s self-report of health variables and previous BP measurements, to prompt them to ask questions during their next physician’s visit about hypertension care (2) the control condition- Web-based preventive health feedback, based on the individual’s self-report of receiving preventive care (e.g., pap testing), to prompt them to ask questions during their next physician’s visit about preventive care. The primary outcome of the study is change in blood pressure and change in the percentage of patients in each group with controlled blood pressure. Conclusion Five hundred participants were enrolled and baseline characteristics include a mean age of 60.0 years; 57.6% female; and 77.6% white. Overall 37.7% participants had uncontrolled blood pressure; the mean body mass index (BMI) was in the obese range (32.4) and 21.8% had diabetes. By activating patients to become involved in their own care, we believe the addition of the web-based intervention will improve blood pressure control compared to a control group who receive web-based preventive messages unrelated to hypertension.

    Background: Laboratory studies suggest that folate intake may decrease blood pressure (BP) through increasing nitric oxide synthesis in endothelial cells and/or reducing plasma homocysteine concentrations. However, human studies, particularly longitudinal data, are limited. Objective: Our objective was to investigate whether dietary folate intake is associated with the 20-y incidence of hypertension. Design: We prospectively followed 4400 men and women (African Americans and whites aged 18–30 y) without hypertension at baseline (1985) in the Coronary Artery Risk Development in Young Adults study 6 times, in 1987, 1990, 1992, 1995, 2000, and 2005. Diet was assessed by dietary-history questionnaire at baseline and in 1992 and 2005. Incident hypertension was defined as the first occurrence at any follow-up examination of systolic BP ≥140 mm Hg, diastolic BP ≥90 mm Hg, or use of antihypertensive medication. Results: A total of 989 incident cases were identified during the 20-y follow-up. After adjustment for potential confounders, participants in the highest quintile of total folate intake had a significantly lower incidence of hypertension (HR: 0.48; 95% CI: 0.38, 0.62; P-trend < 0.01) than did those in the lowest quintile. The multivariable HRs for the same comparison were 0.33 (95% CI: 0.22, 0.51; P-trend < 0.01) in whites and 0.54 (95% CI: 0.40, 0.75; P-trend < 0.01) in African Americans (P-interaction = 0.047). The inverse associations were confirmed in a subset of the cohort (n = 1445) with serum folate measured at baseline and in 1992 and 2000. Conclusions: Higher folate intake in young adulthood was longitudinally associated with a lower incidence of hypertension later in life. This inverse association was more pronounced in whites. Additional studies are warranted to establish the causal inference. PMID:22492371

    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.

    Background Studies have shown sodium restriction to have a beneficial effect on blood pressure (BP) of hypertensive patients. Objective To evaluate the impact of light salt substitution for regular salt on BP of hypertensive patients. Methods Uncontrolled hypertensive patients of both sexes, 20 to 65 years-old, on stable doses of antihypertensive drugs were randomized into Intervention Group (IG - receiving light salt) and Control Group (CG - receiving regular salt). Systolic BP (SBP) and diastolic BP (DBP) were analyzed by using casual BP measurements and Home Blood Pressure Monitoring (HBPM), and sodium and potassium excretion was assessed on 24-hour urine samples. The patients received 3 g of salt for daily consumption for 4 weeks. Results The study evaluated 35 patients (65.7% women), 19 allocated to the IG and 16 to the CG. The mean age was 55.5 ± 7.4 years. Most participants had completed the Brazilian middle school (up to the 8th grade; n = 28; 80.0%), had a family income of up to US$ 600 (n = 17; 48.6%) and practiced regular physical activity (n = 19; 54.3%). Two patients (5.7%) were smokers and 40.0% consumed alcohol regularly (n = 14). The IG showed a significant reduction in both SBP and DBP on the casual measurements and HBPM (p < 0.05) and in sodium excretion (p = 0.016). The CG showed a significant reduction only in casual SBP (p = 0.032). Conclusions The light salt substitution for regular salt significantly reduced BP of hypertensive patients. PMID:25409877

    Patient: Female, 39 Final Diagnosis: Idiopathic pulmonary arterial hypertension Symptoms: Chest pain Medication: — Clinical Procedure: Percutaneous coronary intervention Specialty: Cardiology and Pulmonology Objective: Rare co-existance of disease or pathology Background: Pulmonary artery dilatation is a common feature among patients with severe pulmonary hypertension. Left main coronary artery extrinsic compression by an enlarged pulmonary artery is a rare complication and a potential cause for chest pain and sudden cardiac death in patients with pulmonary hypertension. This situation is very rare and few reports have described it. Currently, the appropriate management of these patients remains unknown. Case Report: In the present report we describe the case of a 39-year-old woman who presented with a 2-year history of cardiac symptoms related to exercise. The patient underwent a 64-slice multidetector computed tomography (MDCT) coronary angiography, which showed left main coronary artery (LMCA) compression by a markedly enlarged pulmonary artery trunk (44 mm), without intraluminal stenosis or coronary artery calcium, as determined by the Agatston score. This compression was considered to be the cause of the cardiac symptoms. To confirm and plan the treatment, the patient underwent cardiac catheterization that confirmed the diagnosis of pulmonary hypertension and LMCA critical obstruction. Taking into account the paucity of information regarding the best management in these cases, the treatment decision was shared among a “heart team” that chose percutaneous coronary intervention with stent placement. An intra-vascular ultrasound was performed during the procedure, which showed a dynamic compression of the left main coronary artery. The intervention was successfully executed without any adverse events. Conclusions: This case illustrates dynamic compression of the LMCA by IVUS, visually demonstrating the mechanism of the intermittent symptoms of myocardial

    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 aim of the study was to estimate and correlate circulating levels of renalase, vascular adhesion protein-1 (VAP-1), catecholamines in patients with primary hypertension. The renalase, VAP-1, and catecholamines concentration was estimated in 121 hypertensive patients. The correlation between renalase, VAP-1 levels and catecholamine concentration in blood, blood pressure control, pharmacological therapy, and medical history were taken in to consideration. The median office blood pressure was 145.5/86 mm Hg and was significantly higher than the median home blood pressure measurement value, which was 135/80 mm Hg, P < .05. Circulating renalase and VAP-1 (Me 9.57 μg/mL and Me = 326.7 ng/mL) levels were significantly higher in patients with hypertension comparing to healthy individuals (3.83 μg/mL and 248.37 ng/mL, P < .05). The correlation between renalase and noradrenalin concentration in blood was observed (r = 0.549; P < .05), also the correlation between VAP-1 and noradrenaline was noticed (r = 0.21, P = .029). Renalase level was higher in patients with coronary artery disease and correlated with decreased ejection fraction. VAP-1 concentration correlated also with left ventricular ejection fraction (r = -0.23, P = .013). Hypertensive patients with diabetes mellitus had almost statistically significant higher VAP-1 concentration compared with hypertensive patients without diabetes mellitus (Me = 403.22 ng/mL vs. Me = 326,68 ng/mL, P = .064). In multiple regression analysis, renalase was predicted by plasma dopamine and norepinephrine as also diastolic office blood pressure and left ventricle ejection fraction. Circulating renalase and VAP-1 levels are elevated in patients with poor blood pressure control. Its correlation with noradrenalin concentration need further studies to find out the role of renalase as also VAP-1 in pathogenesis and treatment of hypertension.

    Background. The purpose of this study was to evaluate the safety and efficacy of transjugular intrahepatic portosystemic shunt (TIPS) placement in the management of portal hypertension in noncirrhotic patients with portal cavernoma. Methods. We conducted a single institution retrospective analysis of 15 noncirrhotic patients with portal cavernoma treated with TIPS placement. 15 patients (4 women and 11 men) were evaluated via the technical success of TIPS placement, procedural complications, and follow-up shunt patency. Results. TIPS placement was technically successful in 11 out of 15 patients (73.3%). Procedure-related complications were limited to a single instance of hepatic encephalopathy in one patient. In patients with successful shunt placement, the portal pressure gradient decreased from 25.8 ± 5.7 to 9.5 ± 4.2 mmHg (P < 0.001). TIPS dysfunction occurred in two patients during a median follow-up time of 45.2 months. Revision was not performed in one patient due to inadequate inflow. The other patient died of massive gastrointestinal bleeding in a local hospital. The remaining nine patients maintained functioning shunts through their last evaluation. Conclusions. TIPS is a safe and effective therapeutic treatment for noncirrhotic patients with symptomatic portal hypertension secondary to portal cavernoma. PMID:24868203

    Although each revision of the US National Cholesterol Education Program guidelines has made increasing provision for the use of global risk assessment in determining need for and intensity of therapy, the guidelines' continued focus on low-density lipoprotein (LDL) cholesterol may result in inadequate or no treatment for individuals at high risk for coronary artery disease (CAD) who do not have substantially elevated LDL cholesterol. However, recent clinical trial evidence has shown that high-risk patients benefit from lipid-regulating therapy regardless of LDL cholesterol level. In the Anglo-Scandinavian Cardiac Outcomes Trial--Lipid Lowering Arm, high-risk hypertensive patients had reductions in clinical events despite not having substantially elevated LDL cholesterol at baseline. These results suggest that all hypertensive patients with additional risk factors should receive lipid-regulating statin therapy to prevent CAD events.

    The Doppler-derived renal resistive index has been used for years in a variety of clinical settings such as the assessment of chronic renal allograft rejection, detection and management of renal artery stenosis, evaluation of progression risk in chronic kidney disease, differential diagnosis in acute and chronic obstructive renal disease, and more recently as a predictor of renal and global outcome in the critically ill patient. More recently, evidence has been accumulating showing that an increased renal resistive index not only reflects changes in intrarenal perfusion but is also related to systemic hemodynamics and the presence of subclinical atherosclerosis, and may thus provide useful prognostic information in patients with primary hypertension. On the basis of these results, the evaluation of renal resistive index has been proposed in the assessment and management of patients with primary hypertension to complement other signs of renal abnormalities.

    We performed a retrospective study in 68 patients (144 procedures) with severe sepsis and intracranial hypertension measured by the pressure in the central retinal vein. The patients underwent high-volume hemofiltration (HV-HF) for extrarenal indications. Increased pressure in the central retinal vein was accompanied by critical points of cerebral perfusion pressure and the growth of neurological deficit with inhibition level of consciousness to coma 1. In this case, IHV-HF may be associated with the formation of the critical points of cerebral perfihsion and severe disorders of microcirculation and the lack of resolution of tissue hypoperfusion. In case of intracranial hypertension IHV-HF is not effective in the category of patients where there is a combination ΔpCO2 > 5.9 mm Hg level and GCS <10 points. PMID:25831703

    Abstract Previous studies suggested that serum gamma-glutamyltransferase (GGT) levels were associated with the prevalence of cardiovascular disease (CVD) risk factors including hypertension, diabetes mellitus (DM), and metabolic syndrome (MetS) in the general population. We aimed to investigate the relationship between serum GGT levels and CVD risk factors in Korean hypertensive patients. This cross-sectional study was based on data from the Korea National Health and Nutrition Examination Survey (KNHANES) 2011 to 2012. The analysis included 1541 hypertensive participants. Study participants were divided into groups according to tertiles of serum GGT with cutoff points of 20 and 35 U/L. Serum GGT levels were positively associated with the components of MetS (P value < 0.05, except for systolic blood pressure and high-density lipoprotein cholesterol). After adjusting for possible confounders, serum GGT levels were associated with an increased risk of MetS, high waist circumference, high triglyceride level, fasting plasma glucose, DM, and the urinary albumin-to-creatinine ratio (P = 0.001). In hypertensive patients, serum GGT levels are positively associated with major cardiovascular risk factors such as MetS, DM, and urinary albumin excretion. PMID:26683926

    The current study examined the degree of blood pressure (BP) control and incidence of myocardial ischemia in hypertensive patients (n=2039) referred for cardiac stress test. Patients were categorized into well-controlled (<140/90 mm Hg), poorly controlled (140-160/90-100 mm Hg), and very poorly controlled (>160/100 mm Hg) groups according to their resting BP. The mean age[±standard error of the mean] of the patients was 68±13 years, and 885 (43.4%) were men. The prevalence of well-controlled hypertension (HTN) was 47.2%, poorly controlled HTN was 29.5%, and very poorly controlled HTN was 23.3%. Evidence of ischemia was seen in 19.8% and 19.3% of the well-controlled and poorly controlled groups, respectively. The very poorly controlled group had the lowest incidence of ischemia (14.3%) (P<.05) compared with the other two groups. Symptoms that mimic ischemic heart disease in hypertensive patients may be partly explained by poorly controlled BP. Quality of care might be improved by optimally controlling BP in patients with angina symptoms prior to ordering diagnostic testing associated with radiation exposure and cost. PMID:26011137

    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.

    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.

    Hypertension is the most common cardiovascular risk factor. Lipoprotein(a) [Lp(a)], inflammation, oxidative stress and chronic kidney disease (CKD) exacerbate the response to tissue injury and acts as markers of the vascular disease, especially in glomerulosclerosis. We compared the clinical characteristics of 138 non-diabetes hypertensive women (ndHT) patients with 417 non-diabetes normotensive subjects and tested the association of hypertension with Lp(a), inflammation, CKD and oxidative stress by using multiple logistic regression. BP, BMI, waist circumference, creatinine, Lp(a), inflammation and malondialdehyde levels were significantly higher and CKD state in the ndHT patients (p < 0.05). Multiple logistic regression showed hypertension associated with increased Lp(a), inflammation, ORs and 95 % CIs were 2.52 (1.33, 4.80), 2.75 (1.44, 5.27) after adjusting for their covariates. Elevated serum Lp(a) and inflammation levels concomitants with increased oxidative stress and CKD were the major risk factors associated with hypertension and implications for the increased risk of HT and vascular disease.

    Carboplatin is a platinum-based anticancer drug that has been long used to treat many types of solid cancer. Because the clearance of carboplatin strongly correlates with the glomerular filtration rate (GFR), its dosage is calculated with the Calvert formula on the basis of the patient's GFR to achieve the target area under the plasma drug concentration-time curve (AUC) for each patient. However, many lines of evidence from previous clinical studies should be interpreted with caution because different methods were used to estimate drug clearance and derive the dosage of carboplatin. There is a particularly high risk of carboplatin overdosing when the dosage is determined on the basis of standardized serum creatinine values. When deciding the dose of carboplatin for adult Japanese patients, preferred methods to assess renal function instead of directly measuring GFR include (1) 24-h urinary collection-based creatinine clearance adjusted by adding 0.2 mg/dl to the serum creatinine concentration measured by standardized methods, and (2) equation-based GFR (eGFR) with a back calculation to units of ml/min per subject. Given the limitations of serum creatinine-based GFR estimations, the GFR or creatinine clearance should be directly measured in each patient whenever possible. To ensure patient safety and facilitate a medical-team approach, the single most appropriate method available at each institute or medical team should be consistently used to calculate the dose of carboplatin with the Calvert formula.

    Cystic fibrosis (CF) is the most common lethal autosomal recessive disease in the white population. Mutation of the CF transmembrane conductance regulator gene on chromosome 7 results in production of abnormally viscous mucus and secretions in the lungs of patients with CF. A similar pathologic process occurs in the gastrointestinal tract, pancreas, and hepatobiliary system. Inspissated mucus causes luminal obstruction and resultant clinical and radiologic complications associated with the disease process. Pancreatic involvement can result in exocrine and endocrine insufficiency, pancreatic atrophy, fatty replacement, or lipomatous pseudohypertrophy. Acute and chronic pancreatitis, pancreatic calcification, cysts, and cystosis also occur. Hepatic manifestations include hepatic steatosis, focal biliary and multilobular cirrhosis, and portal hypertension. Biliary complications include cholelithiasis, microgallbladder, and sclerosing cholangitis. The entire digestive tract can be involved. Distal ileal obstruction syndrome, intussusception, appendicitis, chronic constipation, colonic wall thickening, fibrosing colonopathy, pneumatosis intestinalis, gastroesophageal reflux, and peptic ulcer disease have been described. Renal manifestations include nephrolithiasis and secondary amyloidosis. The educational objectives of this review are to reveal the abdominal manifestations of CF to facilitate focused analysis of cross-sectional imaging in adult patients. Life expectancy in patients with CF continues to improve because of a combination of aggressive antibiotic treatment, improved emphasis on nutrition and physiotherapy, and development of promising new CF transmembrane conductance regulator modulators. As lung function and survival improve, extrapulmonary conditions, including hepatic and gastrointestinal malignancy, will be an increasing cause of morbidity and mortality. Awareness of the expected abdominal manifestations of CF may assist radiologists in identifying

    Emergencies and hypertensive crises are clinical situations which may represent more than 25% of all medical emergency care. Considering such high prevalence, physicians should be prepared to correctly identify these crises and differentiate between urgent and emergent hypertension. Approximately 3% of all visits to emergency rooms are due to significant elevation of blood pressure. Across the spectrum of blood systemic arterial pressure, hypertensive emergency is the most critical clinical situation, thus requiring special attention and care. Such patients present with high blood pressure and signs of acute specific target organ damage (such as acute myocardial infarction, unstable angina, acute pulmonary edema, eclampsia, and stroke). Key elements of diagnosis and specific treatment for the different presentations of hypertensive emergency will be reviewed in this article. The MedLine and PubMed databases were searched for pertinent abstracts, using the key words "hypertensive crises" and "hypertensive emergencies". Additional references were obtained from review articles. Available English language clinical trials, retrospective studies and review articles were identified, reviewed and summarized in a simple and practical way. The hypertensive crisis is a clinical situation characterized by acute elevation of blood pressure followed by clinical signs and symptoms. These signs and symptoms may be mild (headache, dizziness, tinnitus) or severe (dyspnea, chest pain, coma or death). If the patient presents with mild symptoms, but without acute specific target organ damage, diagnosis is hypertensive urgency. However, if severe signs and symptoms and acute specific target organ damage are present, then the patient is experiencing a hypertensive emergency. Some patients arrive at the emergency rooms with high blood pressure, but without any other sign or symptom. In these cases, they usually are not taking their medications correctly. Therefore, this is not a

    Atlantoaxial rotatory fixation (AARF) in adult is a rare disorder that occurs followed by a trauma. The patients were presented with painful torticollis and a typical 'cock robin' position of the head. The clinical diagnosis is generally difficult and often made in the late stage. In some cases, an irreducible or chronic fixation develops. We reported a case of AARF in adult patient which was treated by immobilization with conservative treatment. A 25-year-old female was presented with a posterior neck pain and limitation of motion of cervical spine after a traffic accident. She had no neurological deficit but suffered from severe defect on the scalp and multiple thoracic compression fractures. Plain radiographs demonstrated torticollis, lateral shift of odontoid process to one side and widening of one side of C1-C2 joint space. Immobilization with a Holter traction were performed and analgesics and muscle relaxants were given. Posterior neck pain and limitation of the cervical spine's motion were resolved. Plain cervical radiographs taken at one month after the injury showed that torticollis disappeared and the dens were in the midline position. The authors reported a case of type I post-traumatic AARF that was successfully treated by immobilization alone. PMID:19444353

    Objectives: To assess the relation between white coat hypertension and alterations of left ventricular structure and function. Design: Cross sectional survey. Setting: Augsburg, Germany. Subjects: 1677 subjects, aged 25 to 74 years, who participated in an echocardiographic substudy of the monitoring of trends and determinants in cardiovascular disease Augsburg study during 1994-5. Outcome measures: Blood pressure measurements and M mode, two dimensional, and Doppler echocardiography. After at least 30 minutes’ rest blood pressure was measured three times by a technician, and once by a physician after echocardiography. Subjects were classified as normotensive (technician <140/90 mm Hg, physician <160/95 mm Hg; n=849), white coat hypertensive (technician <140/90 mm Hg, physician ⩾160/95 mm Hg; n=160), mildly hypertensive (technician ⩾140/90 mm Hg, physician <160/95 mm Hg; n=129), and sustained hypertensive (taking antihypertensive drugs or blood pressure measured by a technican ⩾140/90 mm Hg, and physician ⩾160/95 mm Hg; n=538). Results: White coat hypertension was more common in men than women (10.9% versus 8.2% respectively) and positively related to age and body mass index. After adjustment for these variables, white coat hypertension was associated with an increase in left ventricular mass and an increased prevalence of left ventricular hypertrophy (odds ratio 1.9, 95% confidence interval 1.2 to 3.2; P=0.009) compared with normotensive patients. The increase in left ventricular mass was secondary to significantly increased septal and posterior wall thicknesses whereas end diastolic diameters were similar in both groups with white coat hypertension or normotension. Additionally, the systolic white coat effect (difference between blood pressures recorded by a technician and physician) was associated with increased left ventricular mass and increased prevalence of left ventricular hypertrophy (P<0.05 each).

    Abstract The interactions of sodium balance and response of renin–angiotensin–aldosterone system are important for maintaining the hemodynamic stability in physiological conditions. However, the influence of short-term sodium intake intervention in the response of renin–angiotensin system (RAS) on hypertensive patients is still unclear. Thus, we conducted a clinical trial to investigate the effects of short-term sodium intake intervention on the response of RAS in hypertensive patients. One hundred twenty-five primary Chinese hypertensive patients were divided into high, moderate, and low sodium groups by 24-hour urinary sodium excretion (UNa+). All the patients received a 10-day dietary sodium intake intervention with standardized sodium (173.91mmol/day) and potassium (61.53mmol/day). Blood pressure, urinary sodium, urinary potassium, plasma sodium, potassium, creatinine, the levels of plasma renin activity, plasma angiotensin II concentrations (AT-II), and plasma aldosterone concentrations were detected before and after the intervention. Before the intervention, no differences were found in blood pressure and RAS among 3 groups. After standardized dietary sodium intake intervention, both UNa+ excretion and systolic pressure decreased in high-sodium group, while they increased in moderate and low-sodium groups. Intriguingly, there were no changes in the levels of plasma renin activity, AT-II, and plasma aldosterone concentrations among 3 groups during the intervention. The present study demonstrated that the influenced sodium excretion and blood pressure by short-term sodium intake intervention were independent of RAS quick response in Chinese hypertensive patients.

    BACKGROUND: The blood pressure of many treated hypertensive patients remains above recommended target levels. This discrepancy may be related to general practitioners' (GPs') actions. AIM: To assess clinical performance of GPs in blood pressure control in treated hypertensive patients and to explore the influence of patient and GP characteristics on clinical performance. DESIGN OF STUDY: Cross-sectional study conducted on 195 GPs with invitations to participate made via bulletins and by letter. SETTING: One hundred and thirty-two practices in the southern half of The Netherlands from November 1996 to April 1997. METHOD: Performance criteria were selected from Dutch national hypertension guidelines for general practice. GPs completed self-report forms immediately after follow-up visits of hypertensive patients treated with antihypertensive medication. RESULTS: The GPs recorded 3526 follow-up visits. In 63% of these consultations the diastolic blood pressure (DBP) was 90 mmHg or above. The median performance rates of the GPs were less than 51% for most of the recommended actions, even at a DBP of > or = 100 mmHg. Performance of non-pharmacological actions increased gradually with increasing DBP; prescribing an increase in antihypertensive medication and making a follow-up appointment scheduled within six weeks rose steeply at a DBP of > or = 100 mmHg. Patient and GP characteristics contributed little to clinical performance. Action performance rates varied considerably between GPs. CONCLUSION: GPs seem to target their actions at a DBP of below 100 mmHg, whereas guidelines recommend targeting at a DBP of below 90 mmHg. PMID:11271892

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.

    To investigate the prevalence, awareness, treatment, and control of hypertension, and the associated risk factors among adults in Xi'an, China.From October to December 2013, participants in Xi'an, China were recruited for the study by using a multiple-stage sampling method. A self-developed questionnaire with an additional health examination was used to collect data on the history of hypertension diagnosis and antihypertensive medication. The status on prevalence, awareness, treatment, and control of hypertension were analyzed and related risk factors were identified by using logistic regression analysis.A total of 8193 participants were included with an overall prevalence of hypertension of 20.4%. Among the hypertensive participants, 63.7% were aware of their conditions, 47.3% took antihypertensive medication, and 17.8% had their blood pressure (BP) controlled within 140/90 mm Hg. More complications and less frequent BP measurements were associated with hypertension. Older participants, non-drinkers, and those with more complications and more frequent BP measurements were more aware of their hypertension. Being older, living in an urban area, and having more frequent BP measurements were all factors for better treatment. Participants who were women, living in an urban area, with a higher educational level and who were not obese were more likely to have their hypertension controlled.The prevalence of hypertension among adults in Xi'an is high with suboptimal low awareness, treatment, and control rates. Further comprehensive integrated strategies based on these risk factors should be taken into account in order to improve the prevention, awareness, treatment, and control of hypertension.

    The aim of this study was to compare the skills of mindfulness, metacognitive beliefs and perceived stress in hypertension patients and control group. The study was a causal-comparative one. The population included all patients with high blood pressure who were admitted in Isfahan Cardiovascular Research Institute in 2014, 90 of which were selected by purposive sampling. Research instruments include: Kentucky's mindfulness skills (Baer, Smith, & Allen, 2004), metacognitive beliefs questionnaire (Welles, 1997) and questionnaire perceived stress (Cohen & Kamarck, 1983). Of all the questionnaires returned, 80 were fully completed and therefore analyzed. Data were analyzed using a t-test and multivariate analysis of variance. Results showed that there is a difference between mindfulness skills and beliefs of people with hypertension and control group. Moreover, the results showed that there isn't any meaningful difference between the perceived stress in patients with hypertension and control group. It can be said that mindfulness skills, metacognitive beliefs and perceived stress can help us to understand the psychological issues of patients with high blood pressure better. PMID:27530578

    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.

    Backgroud Portal hypertension (PHTN) has been reported to afflict 7-18% of patients with Philadelphia-negative myeloproliferative neoplasms (MPNs), with complications of variceal bleeding and ascites. The clinical features and outcomes of these patients are unclear. Patients and Methods In this multi-centre retrospective study, we evaluated the clinical features of 51 patients with MPNs complicated by PHTN. Results The diagnosis of underlying MPN was most frequently polycythemia vera (PV) (39%) and primary myelofibrosis (MF) (35%), followed by post-PV myelofibrosis (18%), essential thrombocythemia (ET) (4%) and post-ET myelofibrosis (4%). Frequency of JAK2 V617F mutation appears as expected in the underlying MPN. Thrombosis within the splanchnic circulation was prevalent in patients with polycythemia compared to other MPNs (76% vs. 26%, p=0.0007). Conclusions PV and MF patients have a higher incidence of PHTN in our population, with thrombosis contributing to PHTN development in PV patients. Patients with splanchnic circulation thrombosis are potential candidates for screening for portal hypertension. These data may be useful for developing screening strategies for early detection of PHTN in patients with MPN. PMID:25027569
