Patients with adult congenital heart disease have an increased risk of developing pulmonary hypertension. There are several mechanisms of pulmonary hypertension in patients with adult congenital heart disease, and understanding them requires a systematic approach to define the patient's hemodynamics and physiology. This article reviews the updated classification of pulmonary hypertension in patients with adult congenital heart disease with a focus on pathophysiology, diagnostics, and the evaluation of pulmonary hypertension in special adult congenital heart disease populations.

Pulmonary hypertension associated with left-sided heart disease (PH-LHD) is the most common type of pulmonary hypertension. In patients with left-sided heart disease, the presence of pulmonary hypertension is typically a marker of more advanced disease, more severe symptoms, and worse prognosis. In contrast to pulmonary arterial hypertension, PH-LHD is characterised by an elevated pulmonary artery wedge pressure (postcapillary pulmonary hypertension) without or with an additional precapillary component (isolated postcapillary versus combined postcapillary and precapillary pulmonary hypertension). Transthoracic echocardiography is the primary nonin-vasive imaging tool to estimate the probability of pulmonary hypertension and to establish a working diagnosis on the mechanism of pulmonary hyperten-sion. However, right heart catheterisation is always required if significant pulmonary hypertension is sus-pected and exact knowledge of the haemodynamic constellation is necessary. The haemodynamic con-stellation (mean pulmonary artery pressure, mean pulmonary artery wedge pressure, left ventricular end-diastolic pressure) in combination with clinical infor-mation and imaging findings (mainly echocardiog-raphy, coronary angiography and cardiac magnetic resonance imaging) will usually allow the exact mech-anism underlying PH-LHD to be defined, which is a prerequisite for appropriate treatment. The general principle for the management of PH-LHD is to treat the underlying left-sided heart disease in an optimal man-ner using drugs and/or interventional or surgical ther-apy. There is currently no established indication for pulmonary arterial hypertension-specific therapies in PH-LHD, and specific therapies may even cause harm in patients with PH-LHD.

Objective: The purpose of the study was to evaluate the relationship between 201 Tl lung/heart ratio during exercise and left ventricular diastolic function and its diagnostic value on severity of coronary artery disease. Methods: One hundred and two patients with documented coronary artery disease were divided into three groups, including no hypertension, hypertension without or with left ventricular hypertrophy groups. Exercise/delay 201 Tl myocardial perfusion tomography was performed on all patients included. Lung/heart ratio was defined on the anterior planar image obtained during exercise tomography. Results: The lung/heart ratios during exercise in no hypertension (0.43 +- 0.09, P 0.05). The lung/heart ratios of multi-vessel disease subgroup in no hypertension (0.46 +- 0.10 vs 0.40 +- 0.09, P 0.05). When lung/heart ratio was≥0.45, the sensitivities for predicting the presence of multi-vessel disease were 82%, 90%, 40% and specificities were 75%, 75%, 45%, respectively, in no hypertension, hypertension without and with hypertrophy groups. In no hypertension (r=0.402, P 0.05). In no hypertension (r=-0.413, P<0.01), hypertension without (r=-0.662, P<0.01) and with hypertrophy groups (r=-0.408, P<0.05), lung/heart ratios all showed a significant reverse correlation with correspondent E/A ratios. Conclusions: The exercise lung/heart ratios has a better diagnostic value for multi-vessel disease and left ventricular diastolic function abnormalities of coronary artery disease with or without hypertension, but not for multi-vessel disease in hypertension patients complicated with myocardial hypertrophy

2016-05-01

Pulmonary hypertension that develops in the setting of underlying lung diseases such as COPD or idiopathic pulmonary fibrosis (IPF) is associated with decreased functional status, worsening hypoxemia and quality of life, and increased mortality. This complication of lung disease is complex in its origin and carries a unique set of diagnostic and therapeutic issues. This review attempts to provide an overview of mechanisms associated with the onset of pulmonary hypertension in COPD and IPF, touches on appropriate evaluation, and reviews the state of knowledge on treating pulmonary hypertension related to underlying lung disease.

Most cross-sectional studies have found a significant positive relationship between periodontal disease and prehypertension/hypertension. However, these studies had limitations and there are few prospective cohort studies in young adults. The purpose of this prospective cohort study was to investigate whether periodontal disease was related to prehypertension/hypertension in Japanese university students. Students (n = 2,588), who underwent health examinations before entering university and before graduation, were included in the analysis. The association between periodontal disease such as the percentage of bleeding on probing (BOP) and community periodontal index (CPI) scores, and change in blood pressure status was determined. At the reexamination, the numbers of participants with prehypertension (systolic blood pressure 120-139mm Hg or diastolic blood pressure 80-89mm Hg) and hypertension (≥140/90mm Hg) were 882 (34.1%) and 109 (4.2%), respectively. In a logistic regression model, the risk of hypertension was significantly associated with male (odds ratio (OR): 6.31; 95% confidence interval (CI): 2.63-15.13; P periodontal disease defined as the presence of both probing pocket depth (PPD) ≥ 4mm and BOP ≥ 30% at baseline (OR: 2.74; 95% CI: 1.19-6.29; P = 0.02) in participants with prehypertension at baseline. On the other hand, the risk of prehypertension was not associated with presence of periodontal disease (OR: 0.93; 95% CI: 0.51-1.70; P = 0.82). In the short-term prospective cohort study, a significant association between presence of periodontal disease and hypertension was observed in Japanese university students. © American Journal of Hypertension, Ltd 2015.

Pulmonary hypertension has many causes. While it is conventionally thought that the most prevalent is left heart disease, little information about its proportion, causes, and implications on outcome is available. Between 1993 and 2015, 12,115 of 66,949 (18%) first adult transthoracic echocardiograms were found to have tricuspid incompetence gradient ≥40 mm Hg, a pulmonary hypertension surrogate. Left heart disease was identified in 8306 (69%) and included valve malfunction in 4115 (49%), left ventricular systolic dysfunction in 2557 (31%), and diastolic dysfunction in 1776 (21%). Patients with left heart disease, as compared with those without left heart disease, were of similar age, fewer were females (50% vs 63% P pulmonary hypertension with left heart disease.

Increasingly, apparent treatment-resistant hypertension has been recognized. However, much of the prevalence, predictors, and outcomes are largely unknown, especially in patients with coronary artery disease. We evaluated 10,001 patients with coronary artery disease who were enrolled in the Treating to New Targets trial. Apparent treatment-resistant hypertension was defined as blood pressure ≥ 140 mm Hg despite 3 antihypertensive agents or hypertension. In a multivariable model adjusting for baseline differences, the treatment-resistant hypertension group had a 64% increase in primary outcome (hazard ratio [HR], 1.64; 95% confidence interval [CI], 1.39-1.94; P hypertension group. In addition, patients with apparent treatment-resistant hypertension had a 71% increase in major coronary event (P hypertension group. Results were largely similar whether the definition of apparent treatment-resistant hypertension was based on a blood pressure ≥ 140 mm Hg despite 3 agents or a blood pressure hypertension is associated with a marked increase in the risk of cardiovascular morbidity and mortality, including an increase in all-cause death.

2018-03-05

Alzheimer's disease and vascular dementia are responsible for more than 80% of dementia cases. These two conditions share common risk factors including hypertension. Cerebral small vessel disease (CSVD) is strongly associated with both hypertension and cognitive impairment. In this review, we identify the pathophysiological changes in CSVD that are caused by hypertension and further explore the relationship between CSVD and cognitive impairment. We searched and scanned the PubMed database for recently published literatures up to December 2017. We used the keywords of "hypertension", "cerebral small vessel disease", "white matter lesions", "enlarged perivascular spaces", "lacunar infarcts", "cerebral microbleeds", and "cognitive impairment" in the database of PubMed. Articles were obtained and reviewed to analyze the hypertension-induced pathophysiological changes that occur in CSVD and the correlation between CSVD and cognitive impairment. In recent years, studies have demonstrated that hypertension-related changes (e.g., small vascular lesions, inflammatory reactions, hypoperfusion, oxidative stress, damage to autoregulatory processes and the blood-brain barrier, and cerebral amyloid angiopathy) can occur over time in cerebral small vessels, potentially leading to lower cognitive function when blood pressure (BP) control is poor or lacking. Both isolated and co-occurrent CSVD can lead to cognitive deterioration, and this effect may be attributable to a dysfunction in either the cholinergic system or the functionality of cortical and subcortical tracts. We explore the currently available evidence about the hypertensive vasculopathy and inflammatory changes that occur in CSVD. Both are vital prognostic indicators of the development of cognitive impairment. Future studies should be performed to validate the relationship between BP levels and CSVD progression and between the numbers, volumes, and anatomical locations of CSVD and cognitive impairment.

Lee, Hwa Yeon; Yoo, Seung Min; Kim, Hye Rin; Chun, Eun Ju; White, Charles S

To evaluate the diagnostic accuracy of chest CT findings to diagnose Grave's disease in pulmonary hypertension. We retrospectively evaluated chest CT and the medical records of 13 patients with Grave's disease with (n=6) or without pulmonary hypertension (n=7) and in 17 control patients. Presence of iso-attenuation of diffusely enlarged thyroid glands compared with adjacent neck muscle on non-enhanced CT as a diagnostic clue of Grave's disease, and assessment of pulmonary hypertension on CT has high diagnostic accuracy. Chest CT has the potential to diagnose Grave's disease with pulmonary hypertension in the absence of other information. Copyright © 2017 Elsevier Inc. All rights reserved.

Accelerated Vascular Aging as a Paradigm for Hypertensive Vascular Disease: Prevention and Therapy.

Science.gov (United States)

Barton, Matthias; Husmann, Marc; Meyer, Matthias R

2016-05-01

Aging is considered the most important nonmodifiable risk factor for cardiovascular disease and death after age 28 years. Because of demographic changes the world population is expected to increase to 9 billion by the year 2050 and up to 12 billion by 2100, with several-fold increases among those 65 years of age and older. Healthy aging and prevention of aging-related diseases and associated health costs have become part of political agendas of governments around the world. Atherosclerotic vascular burden increases with age; accordingly, patients with progeria (premature aging) syndromes die from myocardial infarctions or stroke as teenagers or young adults. The incidence and prevalence of arterial hypertension also increases with age. Arterial hypertension-like diabetes and chronic renal failure-shares numerous pathologies and underlying mechanisms with the vascular aging process. In this article, we review how arterial hypertension resembles premature vascular aging, including the mechanisms by which arterial hypertension (as well as other risk factors such as diabetes mellitus, dyslipidemia, or chronic renal failure) accelerates the vascular aging process. We will also address the importance of cardiovascular risk factor control-including antihypertensive therapy-as a powerful intervention to interfere with premature vascular aging to reduce the age-associated prevalence of diseases such as myocardial infarction, heart failure, hypertensive nephropathy, and vascular dementia due to cerebrovascular disease. Finally, we will discuss the implementation of endothelial therapy, which aims at active patient participation to improve primary and secondary prevention of cardiovascular disease.

Ischemic heart disease (IHD) is the most important cause of mortality worldwide. Although the awareness of cardiovascular risk factors and IHD in women has increased over the last decades, mortality rates are still higher in women than in men. Among traditional cardiovascular risk factors, hypertension is associated with a greater risk for IHD in women as compared to men. In this review, discuss gender differences in epidemiology and pathophysiology of hypertension and its impact on the incidence and outcomes of IHD in women. We also, discuss some "women conditions" such as hypertensive disorders in pregnancy (HDP) and polycystic ovarian syndrome (PCOS). Even though this is not a systematic review, English-language studies on MEDLINE and the Cochrane Database of Systematic reviews were searched for consultation and analysis. Hypertension display different epidemiological patterns in men and women. Studies have shown that hypertension has a different proatherogenic effects in men and women. Hypertension has a direct effect on microcirculation, but estrogens have a protective role in this regard in premenopausal women. However, after the decline in estrogen levels, women are exposed to the same cardiovascular risk as males. Postmenopausal women exhibit a greater burden of cardiovascular risk factors, which together with microvascular dysfunction and smaller and stiffer arteries conducts to the worse prognosis observed in women with IHD. "Women specific conditions" such as HDP and PCOS affects 10% of pregnant women and women in reproductive age, respectively. These conditions are associated with increased risk of hypertension and IHD later in life. Although women are more aware of their hypertension, cardiovascular mortality is higher in hypertensive women with comorbid IHD. Yet these gender disparities in outcomes seem to be attenuated with effective therapy. The pathophysiology of IHD is gender specific, women with ischemic symptoms presenting less often with

Background & Aims Little is known about the prevalence and severity of portal hypertension in patients with non-alcoholic fatty liver disease (NAFLD). We investigated the prevalence and non-invasive predictors of portal hypertension in patients with NAFLD. Methods Signs of portal hypertension, including esophageal varices, splenomegaly, portosystemic encephalopathy, and ascites where investigated in 354 patients with NAFLD. Results One-hundred patients had portal hypertension at the time of NAFLD diagnosis (28.2%), 88 of these with septal fibrosis or cirrhosis (88%). Fibrosis stage correlated with presence (r=0.41, Pportal hypertension. Of the 204 patients with no or mild fibrosis (stages 0–2), 12 had portal hypertension (6%); they had a significantly higher grade of steatosis, based on biopsy analysis, compared to the 192 patients without portal hypertension (94%). Thrombocytopenia, hyperbilirubinemia, cirrhosis, and obesity were independently associated with portal hypertension. Esophageal varices were found in 57 of the 128 patients undergoing endoscopic screening (44.5%) and independently associated with thrombocytopenia, type 2 diabetes, and splenomegaly. Conclusions Signs of portal hypertension are present in 25% of patients at the time of diagnosis of NAFLD; most had advanced fibrosis or cirrhosis. Portal hypertension can occur in a small proportion of patients with mild or no fibrosis and is associated with the extent of steatosis. Features of advanced liver disease and insulin resistance might identify patients with NAFLD and portal hypertension, and those expected to derive the most benefit from endoscopic screening for esophageal varices.

Cerebrovascular impairment is frequent in patients with Alzheimer disease and is believed to influence clinical manifestation and severity of the disease. Cardiovascular risk factors, especially hypertension, have been associated with higher risk of developing Alzheimer disease. To investigate the mechanisms underlying the hypertension, Alzheimer disease cross talk, we established a mouse model of dual pathology by infusing hypertensive doses of angiotensin II into transgenic APPPS1 mice overexpressing mutated human amyloid precursor and presenilin 1 proteins. At 4.5 months, at the early stage of disease progression, only hypertensive APPPS1 mice presented impairment of temporal order memory performance in the episodic-like memory task. This cognitive deficit was associated with an increased number of cortical amyloid deposits (223±5 versus 207±5 plaques/mm(2); P<0.05) and a 2-fold increase in soluble amyloid levels in the brain and in plasma. Hypertensive APPPS1 mice presented several cerebrovascular alterations, including a 25% reduction in cerebral microvessel density and a 30% to 40% increase in cerebral vascular amyloid deposits, as well as a decrease in vascular endothelial growth factor A expression in the brain, compared with normotensive APPPS1 mice. Moreover, the brain levels of nitric oxide synthase 1 and 3 and the nitrite/nitrate levels were reduced in hypertensive APPPS1 mice (by 49%, 34%, and 33%, respectively, compared with wild-type mice; P<0.05). Our results indicate that hypertension accelerates the development of Alzheimer disease-related structural and functional alterations, partially through cerebral vasculature impairment and reduced nitric oxide production. © 2014 American Heart Association, Inc.

Mineralocorticoid hypertension

Vishal Gupta

2011-01-01

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

Recent studies suggest potential adverse effects of methylmercury exposure on myocardial infarction and hypertension, although the evidence is still limited. We thus evaluated this association using age-standardized mortality ratios (ASMRs) in Minamata, where severe methylmercury poisoning had occurred. We obtained mortality data from annual vital statistics and demographic statistics from census. We then compared mortality of atherosclerotic heart disease including degenerative heart disease and hypertension in Minamata-city with those in Kumamoto Prefecture, which includes Minamata city, as a control. We estimated ASMRs and 95% confidence intervals (CIs) during the period from 1953 to 1970. ASMRs of atherosclerotic heart disease were continuously decreased during the period from 1953 to 1967. In contrast, the ASMR of hypertension was significantly elevated during the period from 1963 to 1967 (SMR=1.38, CI; 1.06-1.80); but they decreased later. Although dilution is present in this ecological study, our study supports the notion that methylmercury exposure induces hypertension. Copyright © 2011 Elsevier B.V. All rights reserved.

The objective of this multicenter cross-sectional study was to investigate the relationship of nocturnal polyuria in patients with common lifestyle related diseases and overactive bladder, with special attention to hypertension. After baseline assessment, patients recorded 24-hour urinary frequency/volume, blood pressure and heart rate for 3 days. They were stratified into 4 groups based on mean blood pressure, including no hypertension, and controllable, untreated and uncontrolled hypertension, respectively. The 2,353 eligible patients, who had urinary urgency once or more per week and 1 or more nocturnal toilet visits, were enrolled from 543 sites in Japan. Of these patients complete data, including the 24-hour frequency volume chart, were collected from 1,271. Multivariable analyses showed a statistically significant association of nocturnal polyuria with increasing age (OR 1.04, 95% CI 1.02-1.05, p polyuria in women alone (p = 0.01 and 0.03, respectively). Lower urinary tract symptoms suggestive of benign prostatic hyperplasia were significantly associated with nocturnal polyuria in men alone (p polyuria was significantly associated with age, male gender, and untreated hypertension in patients with lifestyle related diseases and overactive bladder.

Nasrallah, Rania; Hassouneh, Ramzi

2016-01-01

An important measure of cardiovascular health is obtained by evaluating the global cardiovascular risk, which comprises a number of factors, including hypertension and type 2 diabetes, the leading causes of illness and death in the world, as well as the metabolic syndrome. Altered immunity, inflammation, and oxidative stress underlie many of the changes associated with cardiovascular disease, diabetes, and the metabolic syndrome, and recent efforts have begun to elucidate the contribution of PGE2 in these events. This review summarizes the role of PGE2 in kidney disease outcomes that accelerate cardiovascular disease, highlights the role of cyclooxygenase-2/microsomal PGE synthase 1/PGE2 signaling in hypertension and diabetes, and outlines the contribution of PGE2 to other aspects of the metabolic syndrome, particularly abdominal adiposity, dyslipidemia, and atherogenesis. A clearer understanding of the role of PGE2 could lead to new avenues to improve therapeutic options and disease management strategies. PMID:26319242

Hypertension, obesity, and coronary artery disease in the survivors of congenital heart disease.

Roche, S Lucy; Silversides, Candice K

2013-07-01

Obesity, hypertension, and coronary artery disease are prevalent in the general population and well recognized as contributors to cardiac morbidity and mortality. With surgical and medical advances, there is a growing and aging population with congenital heart disease who are also at risk of developing these comorbidities. In addition, some congenital cardiac lesions predispose patients to conditions such as hypertension or coronary artery disease. The effect of these comorbidities on the structurally abnormal heart is not well understood, but might be very important, especially in those with residual abnormalities. Thus, in addition to surveillance for and treatment of late complications it is important for the congenital cardiologist to consider and aggressively manage acquired comorbidities. In this review we explore the prevalence of hypertension, obesity, and coronary artery disease, discuss congenital lesions that predispose to these conditions and review management strategies for this unique population.

Lyle, Pamela L; Weber, Robert D; Bogarin, Javier; Kircher, Tobias

2009-01-01

Whipple disease is a rare multisystemic disorder of infectious aetiology caused by Tropheryma whipplei. Pulmonary hypertension is a rare association for which the underlying pathophysiological mechanism is unclear. Our patient was a 54-year-old man with a 1-year history of progressive polyarticular arthritis, and worsening respiratory and gastrointestinal symptoms. Pulmonary artery catheterisation demonstrated moderate-to-severe pulmonary hypertension. Duodenal biopsies, with electron microscopy, were diagnostic of Whipple disease. Involvement by Whipple disease was also evident in the stomach, bone marrow and pulmonary pleura. A 2-week course of intravenous ceftriaxone was initiated and this was followed by a 1-year course of trimethoprim/sulfamethoxazole (160/800), once daily. Nine months into antibiotic treatment, a repeat echocardiogram showed normalisation of the size and function of the cardiac chambers, including the right atrium and right ventricle. There was complete resolution of the severe tricuspid insufficiency and pulmonary hypertension. Whipple disease is not generally considered as a possible cause of pulmonary hypertension but such awareness is important given that it may be potentially reversible with antibiotic therapy.

The reasons and levels of inadequacy of antihypertensive therapy in this group of patients are well-known.Aim. To evaluate the awareness level of own disease, adequacy of therapy only in those patients with stable mild arterial hypertension, who are complied with recommendations of physicians concerning AH treatment and changing of mode of life. It was also planned to reveal possible grounds for inadequate secondary prevention of cardiovascular disease.Materials and methods. 76 patiens with stable mild arterial hypertension were included into study. They didn’t have any serious concomitant diseases and were complied with the recommendations of physicians concerning secondary prevention of cardiovascular disease. Questionnaire of State Research Center for Preventive Medicine “Assessment of awareness level of own disease in patients with stable arterial hypertension” was used in the study.Results. It was revealed, that the majority of patients, invoved in the study, were nonsmokers and regularly took antihypertensive drugs. 70% of questioned patients reached the target arterial blood pressure levels, while patients with arterial hypertension in general Russia population received regular and efficient treatment in less than 30-20%. Drugs treatment of questioned patients almost didn’t differ from that, which received patients in out-patient clinics of Moscow: in both cases ACE inhibitors were preferred. Only 29% of questioned patients knew their lipid levels in blood and none of the patients took drugs, reducing levels of lipids in blood. Half of the patients, that took part in our study, had increased level of body mass index.Conclusions. Inadequate

Common chronic diseases such as hypertension are costly and difficult to manage. Our ultimate goal is to use data from electronic health records to predict the risk and timing of deterioration in hypertension control. Towards this goal, this work predicts the transition points at which hypertension is brought into, as well as pushed out of, control. In a cohort of 1294 patients with hypertension enrolled in a chronic disease management program at the Vanderbilt University Medical Center, patients are modeled as an array of features derived from the clinical domain over time, which are distilled into a core set using an information gain criteria regarding their predictive performance. A model for transition point prediction was then computed using a random forest classifier. The most predictive features for transitions in hypertension control status included hypertension assessment patterns, comorbid diagnoses, procedures and medication history. The final random forest model achieved a c-statistic of 0.836 (95% CI 0.830 to 0.842) and an accuracy of 0.773 (95% CI 0.766 to 0.780). This study achieved accurate prediction of transition points of hypertension control status, an important first step in the long-term goal of developing personalized hypertension management plans.

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.

To compare the incidence of pregnancy-induced hypertension in patients with and without polycystic ovary disease (PCOD). We conducted a retrospective, case-control analysis of patients who achieved singleton pregnancies with human menopausal gonadotropin (hMG) therapy. Twenty-two PCOD patients were compared to 27 infertility patients without PCOD who were pregnant after hMG therapy. Non-PCOD patients received hMG for superovulation as part of superovulation/intrauterine insemination or in vitro fertilization/embryo transfer. PCOD patients were receiving hMG for simple ovulation induction. Pregnancy-induced hypertension was defined as late pregnancy blood pressure > 140/90 mm Hg on two readings six hours apart and return to normal blood pressure by four to six weeks postpartum. There were no differences between PCOD and non-PCOD patients with reference to age, body mass index, parity or other pregnancy-induced hypertension risk factors (i.e., chronic hypertension, diabetes or chronic renal disease). Pregnant PCOD patients had a much higher incidence of pregnancy-induced hypertension, 31.8% (7/22), versus non-PCOD patients, who only had a pregnancy-induced hypertension incidence of 3.7% (1/27) (P = .016, OR = 12.1, 95% CI = 1.3-566.8). PCOD patients are at very high risk of pregnancy-induced hypertension when pregnant after ovulation induction.

Out of proportion pulmonary hypertension in obstructive lung diseases.

Chatterjee, Kshitij; Tarawneh, Ahmad R; Alam, Shoaib

2018-03-01

Pulmonary hypertension is common (25-90%) in chronic obstructive pulmonary diseases (COPDs). Severe pulmonary hypertension, however, is quite rare (1-3%). The term 'out of proportion' pulmonary hypertension is still widely used. New guidelines instead propose to use the term 'Severe pulmonary hypertension' if mean pulmonary arterial pressure at least 35 mmHg or cardiac index (CI) is less than 2.0 l/min/m on right heart catheterization (RHC). Why only a minority of COPD patients develop severe pulmonary hypertension is unclear. When present, severe pulmonary hypertension in COPD is associated with increased dyspnea and decreased survival and often does not closely correlate with degree of obstructive abnormality on pulmonary function testing. COPD patients with severe pulmonary hypertension experience circulatory limitation at maximum exercise, and not ventilatory limitation, which is typical for moderate-to-severe COPD patients with no or moderate pulmonary hypertension. There is no conclusive evidence to support or completely reject the possibility of the use of specific pulmonary arterial hypertension (PAH) therapies in pulmonary hypertension associated with COPD. In mild-to-moderate COPD patients who have severe and progressive symptoms, and have evidence of severe pulmonary hypertension on RHC, specific PAH therapies may be used similar to WHO group-I PAH guidelines.

Abnormality of circadian blood pressure (BP) variation, i.e. non-dipper, riser, nocturnal hypertension etc, is brought by several pathophysiological conditions especially by secondary hypertension. These pathophysiological conditions are classified into several categories, i.e. disturbance of autonomic nervous system, metabolic disorder, endocrine disorder, disorder of Na and water excretion (e.g. sodium sensitivity), severe target organ damage and ischemia, cardiovascular complications and drug induced hypertension. Each pathophysiological condition which brings disturbance of circadian BP variation is included in several categories, e.g. diabetes mellitus is included in metabolic disorder, autonomic imbalance, sodium sensitivity and endocrine disorder. However, it seems that unified principle of the genesis of disturbance of circadian BP variation in many pathophysiological conditions is autonomic imbalance. Thus, it is concluded that disturbance of circadian BP variation is not purposive biological behavior but the result of autonomic imbalance which looks as if compensatory reaction such as exaggerated Na-water excretion during night in patient with Na-water retention who reveals disturbed circadian BP variation.

This study aims to determine whether successful laparoscopic fundoplication for gastroesophageal reflux disease (GERD) can improve the control of hypertension. We conducted an observational study of GERD patients with hypertension. The esophageal and gastroesophageal symptoms of these patients were successfully treated with laparoscopic fundoplication, as measured by the reduced GERD symptoms and proton pump inhibitor consumption. A hypertension control scale was used to classify the use of antihypertensive medications and the quality of blood pressure control before and after anti-reflux surgery.Wilcoxon signed-ranks test was used for the statistical analyses. Seventy GERD patients were included in the analysis and followed up for a mean period of 3.5 ± 1.4 years. Prior to surgery, all participating patients were taking at least one class of antihypertensive medication, and 56 patients (80%) had intermittently high blood pressure. After surgery, the mean number of antihypertensive medication classes per patient was significantly reduced from 1.61 ± 0.77 pre-procedure to 1.27 ± 0.88 post-procedure (P gastroesophageal reflux and hypertension.

ESSENTIAL ARTERIAL HYPERTENSION AND RISK FACTORS ASSOCIATED WITH HYPERTENSIVE NEPHROPATHY

Full Text Available Arterial hypertension is a major risk factor that predisposes to cardiovascular disorders and is responsible for most of the morbidity and mortality in patients. Hypertension is closely associated with the kidney, because kidney disease can be both the cause and consequence of increased blood pressure. Elevation of blood pressure is a strong independent risk factor for hypertensive nephropathy and development of ESRD. The pathogenesis of ischemic hypertensive nephropathy (IHN is multifactoral, and in addition to blood pressure other factors contribute to the development of this renal pathology and its progression to end-stage renal disease. These include obesity, smoking, male gender and other still unknown risk factors. The aim of this paper was to analyse the association between essential arterial hypertension and renal hypertensive disease and prevalence of other atherosclerotic risk factors in patients with developed hypertensive renal disease. In this prospective cross sectional study 283 patients of both genders with diagnosed essential hypertension and hypertensive renal disease were analysed. The anamnestic data related to age, duration of hypertension, history of smoking, presence of hypertensive retinopathy, hypertrophy of the left chamber and data about previous renal diseases were collected through conversation and medical documentation. The clinical examination comprise determination of blood pressure, body mass index (BMI, lipid parameters (total cholesterol, LDL cholesterol, HDL cholesterol and triglycerides, serum urea and creatinine, urine, albumin and protein concentration. The total number of 283 patients (185 males and 98 females with HN was analyzed. The analysis revealed significantly higher proportion of males aged over 60 years with IHN. The mean age of examined hypertensive patients with IHN is 62.6±8.8 years with duration of hypertension 19.8±5.9 years. All examined patients had hypertensive retinopathy and

Hypertension is both a cause and consequence of chronic kidney disease (CKD). According to the Chinese national survey in 2007-2010, the prevalence of CKD was much higher in hypertensive patients (18.9%, n=16,691) than in the overall population sample (10.8%, n=47,204). CKD in hypertension confers risks to the kidneys as well as other organs. Probably because of high dietary salt intake, Asian hypertensive patients with CKD show high prevalence of non-dipping and reversed dipping blood pressure pattern, and may have even higher risks of cardiovascular disease. Therefore, out-of-office blood pressure evaluation and comprehensive cardiovascular evaluations are required. Most of current hypertension guidelines recommend intensive antihypertensive treatment in hypertensive patients with CKD. This is probably of particular relevance for cardiovascular prevention in Asia, because stroke, as a major complication of hypertension in Asia, is more closely related to blood pressure than coronary events. Intensive blood pressure control to 130/80 mmHg is often required to prevent CKD progression and cardiovascular complications. The inhibitors of the renin-angiotensin system (RAS) are recommended as the first line antihypertensive medications in patients with a glomerular filtration rate higher than 30 ml/min/1.73 m², which may more efficaciously prevent end-stage renal disease and cardiovascular events. Nonetheless, combination therapy of RAS inhibitors with other classes of antihypertensive drugs, such as calcium-channel blockers, diuretics, etc, is required to control blood pressure to the target.

Computational analysis of candidate disease genes and variants for Salt-sensitive hypertension in indigenous Southern Africans

KAUST Repository

Tiffin, Nicki

2010-09-27

Multiple factors underlie susceptibility to essential hypertension, including a significant genetic and ethnic component, and environmental effects. Blood pressure response of hypertensive individuals to salt is heterogeneous, but salt sensitivity appears more prevalent in people of indigenous African origin. The underlying genetics of salt-sensitive hypertension, however, are poorly understood. In this study, computational methods including text- and data-mining have been used to select and prioritize candidate aetiological genes for salt-sensitive hypertension. Additionally, we have compared allele frequencies and copy number variation for single nucleotide polymorphisms in candidate genes between indigenous Southern African and Caucasian populations, with the aim of identifying candidate genes with significant variability between the population groups: identifying genetic variability between population groups can exploit ethnic differences in disease prevalence to aid with prioritisation of good candidate genes. Our top-ranking candidate genes include parathyroid hormone precursor (PTH) and type-1angiotensin II receptor (AGTR1). We propose that the candidate genes identified in this study warrant further investigation as potential aetiological genes for salt-sensitive hypertension. © 2010 Tiffin et al.

Gaucher disease is the most common form of hereditary enzymopathies combined into a group of lysosomal storage diseases. The basis for the disease is a hereditary deficiency of the activity of acid β-glucosidase, a lysosomal enzyme involved in the catabolism of lipids, which results in the accumulation of nonutilized cellular metabolism products in the macrophage lysosomes. The main clinical manifestations of type 1 Gaucher disease are cytopenia, hepatomegaly, and splenomegaly, and bone lesion. One of the atypical clinical manifestations of Gaucher disease is damage to the lungs with the development of pulmonary hypertension, which is usually considered within the underlying disease - the development of pneumosclerosis due to macrophage dysfunction. The paper describes a case of progressive pulmonary hypertension in a patient with type 1 Gaucher disease.

Ghrelin is involved in several metabolic and cardiovascular processes. Recent evidence suggests its involvement in blood pressure regulation and hypertension. The aim of the study was to determine associations of single-nucleotide polymorphisms (SNPs) and haplotypes of the ghrelin gene (GHRL) with hypertension and atherosclerotic disease. Six GHRL SNPs (rs27647, rs26802, rs34911341, rs696217, rs4684677 and a -473G/A (with no assigned rsID)) were investigated in a sample of 1143 hypertensive subjects and 1489 controls of Caucasian origin. Both single-locus and haplotype association analyses were performed. In single-locus analyses, only the non-synonymous rs34911341 was associated with hypertension (odds ratio (OR)=1.95 (95% confidence interval (CI): 1.26-3.02), P=0.003). Six common haplotypes with frequency >1% were inferred from the studied GHRL SNPs, and their frequency distribution was significantly different between hypertensive subjects and controls (chi(2)=12.96 with 5 d.f. (degree of freedom), P=0.024). The effect of rs26802 was found to be significantly (P=0.017) modulated by other GHRL SNPs, as its C allele conferred either an increased risk (OR=1.30 (1.08-1.57), P=0.005) or a decreased risk (OR=0.50 (0.23-1.06), P=0.07) of hypertension according to the two different haplotypes on which it can be found. No association of GHRL SNPs or haplotypes with atherosclerotic disease was observed. In conclusion, we observed statistical evidence for association between GHRL SNPs and risk of hypertension.

Patients in the early stage of hypertensive heart disease tend to have normal echocardiographic findings. The aim of this study was to investigate whether pathology-specific echocardiographic morphologic and functional parameters can help to detect subclinical hypertensive heart disease. One hundred ten consecutive patients without a history and medication for arterial hypertension (AH) or other cardiac diseases were enrolled. Standard echocardiography and two-dimensional speckle-tracking-imaging analysis were performed. Resting blood pressure (BP) measurement, cycle ergometer test (CET), and 24-hour ambulatory BP monitoring (ABPM) were conducted. Patients were referred to "septal bulge (SB)" group (basal-septal wall thickness ≥ 2 mm thicker than mid-septal wall thickness) or "no-SB" group. Echocardiographic SB was found in 48 (43.6%) of 110 patients. In this SB group, 38 (79.2%) patients showed AH either by CET or ABPM. In contrast, in the no-SB group (n = 62), 59 (95.2%) patients had no positive test for AH by CET or ABPM. When AH was solely defined by resting BP, SB was a reasonable predictive sign for AH (sensitivity 73%, specificity 76%). However, when AH was confirmed by CET or ABPM the echocardiographic SB strongly predicted clinical AH (sensitivity 93%, specificity 86%). In addition, regional myocardial deformation of the basal-septum in SB group was significantly lower than in no-SB group (14 ± 4% vs. 17 ± 4%; P heart disease. Sophisticated BP evaluation including resting BP, ABPM, and CET should be performed in all patients with an accidental finding of a SB in echocardiography. Copyright © 2016 The Authors.

Full Text Available Jennifer Frank, David SommerfeldUniversity of Wisconsin School of Medicine and Public Health, Department of Family Medicine, Appleton, WI, USAAbstract: Resistant hypertension, defined as failure to achieve target blood pressure despite the use of optimal or maximum doses of at least 3 agents, one of which is a diuretic, or requiring 4 or more medications to achieve blood pressure goal, is likely to affect up to 20% of all patients with hypertension. Apparent resistant hypertension may be caused by medication nonadherence, substances that either interfere with antihypertensive mediations or cause blood pressure elevation, and under- or inappropriate medication treatment. Certain patient characteristics are associated with the presence of resistant hypertension and include chronic kidney disease, diabetes, obesity, and presence of end-organ damage (microalbuminuria, retinopathy, left-ventricular hypertrophy. Secondary causes of resistant hypertension are not uncommon and include obstructive sleep apnea, chronic kidney disease, primary aldosteronism, renal artery stenosis, pheochromocytoma, and Cushing’s disease. Initial medication management usually includes adding or increasing the dose of a diuretic, which is effective in lowering the blood pressure of a large number of patients with resistant hypertension. Additional management options include maximizing lifestyle modification, combination therapy of antihypertensive agents depending on individual patient characteristics, adding less-commonly used fourth- or fifth-line antihypertensive agents, and referral to a hypertension specialist.Keywords: resistant hypertension, blood pressure, diuretic

2013-01-01

Pulmonary hypertension is defined as an increase of mean pulmonary arterial pressure ≥25 mmHg at rest as assessed by right heart catheterization. According to different combinations of values of pulmonary wedge pressure, pulmonary vascular resistance and cardiac output, a hemodynamic classification of pulmonary hypertension has been proposed. Of major importance is the pulmonary wedge pressure which allows to distinguish pre-capillary (pulmonary wedge pressure ≤15 mmHg) and post-capillary (pulmonary wedge pressure >15 mmHg) pulmonary hypertension. Pre-capillary pulmonary hypertension includes the clinical groups 1 (pulmonary arterial hypertension), 3 (pulmonary hypertension due to lung diseases and/or hypoxia), 4 (chronic thrombo-embolic pulmonary hypertension) and 5 (pulmonary hypertension with unclear and/or multifactorial mechanisms). Post-capillary pulmonary hypertension corresponds to the clinical group 2 (pulmonary hypertension due to left heart diseases).

2016-01-01

Pulmonary hypertension is a common complication of degenerative mitral valve disease, and contributes significantly to both morbidity and mortality. The use of medications for reduction of pulmonary pressure in patients is not a common practice by most physicians in this part of the world because of the absence of data on pulmonary hypertension. The authors set out to find the prevalence of pulmonary hypertension in patients with degenerative mitral valve disease and to determine if there are gender differences in affectation. This will form a basis for future research on the management of pulmonary hypertension in sub-Saharan Africa. The echocardiographic records of 1390 patients carried out over a period of 4 years were retrospectively reviewed. The examinations were done with a Logic 500 MD echocardiographic machine. Tricuspid valve regurgitation velocity above 250 cm/s defined pulmonary hypertension. Data obtained included presence of degenerative mitral valve disease, pulmonary hypertension, age, and gender. A total of 1390 echocardiogram reports done at Conquest Medical Imaging, Enugu, from July 2009 to August 2013 were retrospectively reviewed. Degenerative mitral valve disease was noted in 18.7% of the patients, (259/1390) made up of 149 males and 110 females with a mean age of 68.3 (14.4) years. Pulmonary hypertension was present in 30% of the patients (78/259) and affected males more than females. Pulmonary hypertension is common in patients with degenerative mitral valve disease in Enugu, and affects males more than females.

Full Text Available Connective tissue diseases (CTD, such as systemic sclerosis (SSc, systemic lupus erythematosus (SLE, and mixed connective tissue disease (MCTD, develop pulmonary hypertension (PH. Generally all PH cases associated with any CTD are classified into the same PH group. However, histological examination shows both common and specific lesions for each disease. In patients with SLE, fibrosis is generally rare and mild. The findings of PH in SLE are similar to those in primary pulmonary hypertension. Many cases of SSc are accompanied by fibrosis. MCTD is rather close to SSc. Arterial and arteriolar lesions of MCTD are characterized by fibrous intimal thickening. In this review, we describe the pathological features of PH associated with each CTD.

Pathophysiology and treatment of pulmonary hypertension in sickle cell disease

Pulmonary hypertension affects ∼10% of adult patients with sickle cell disease (SCD), particularly those with the homozygous genotype. An increase in pulmonary artery systolic pressure, estimated noninvasively by echocardiography, helps identify SCD patients at risk for pulmonary hypertension, but definitive diagnosis requires right-heart catheterization. About half of SCD-related pulmonary hypertension patients have precapillary pulmonary hypertension with potential etiologies of (1) a nitric oxide deficiency state and vasculopathy consequent to intravascular hemolysis, (2) chronic pulmonary thromboembolism, or (3) upregulated hypoxic responses secondary to anemia, low O2 saturation, and microvascular obstruction. The remainder have postcapillary pulmonary hypertension secondary to left ventricular dysfunction. Although the pulmonary artery pressure in SCD patients with pulmonary hypertension is only moderately elevated, they have a markedly higher risk of death than patients without pulmonary hypertension. Guidelines for diagnosis and management of SCD-related pulmonary hypertension were published recently by the American Thoracic Society. Management of adults with sickle-related pulmonary hypertension is based on anticoagulation for those with thromboembolism; oxygen therapy for those with low oxygen saturation; treatment of left ventricular failure in those with postcapillary pulmonary hypertension; and hydroxyurea or transfusions to raise the hemoglobin concentration, reduce hemolysis, and prevent vaso-occlusive events that cause additional increases in pulmonary pressure. Randomized trials have not identified drugs to lower pulmonary pressure in SCD patients with precapillary pulmonary hypertension. Patients with hemodynamics of pulmonary arterial hypertension should be referred to specialized centers and considered for treatments known to be effective in other forms of pulmonary arterial hypertension.

The association between hypertensive pregnancy disorders and cardiovascular disease later in life is well described. In this study we aim to develop a prognostic model from patients characteristics known before, early in, during and after pregnancy to identify women at increased risk of cardiovascular disease e.g. chronic hypertension years after pregnancy complicated by hypertension at term. We included women with a history of singleton pregnancy complicated by hypertension at term. Women using antihypertensive medication before pregnancy were excluded. We measured hypertension in these women more than 2years postpartum. Different patients characteristics before, early in, during and after pregnancy were considered to develop a prognostic model of chronic hypertension at 2-years. These included amongst others maternal age, blood pressure at pregnancy intake and blood pressure six weeks post-partum. Univariable analyses followed by a multivariable logistic regression analysis was performed to determine which combination of predictors best predicted chronic hypertension. Model performance was assessed by calibration (graphical plot) and discrimination (area under the receiver operating characteristic (AUC)). Of the 305 women in who blood pressure 2.5years after pregnancy was assessed, 105 women (34%) had chronic hypertension. The following patient characteristics were significant associated with chronic hypertension: higher maternal age, lower education, negative family history on hypertensive pregnancy disorders, higher BMI at booking, higher diastolic blood pressure at pregnancy intake, higher systolic blood pressure during pregnancy and higher diastolic blood pressure at six weeks post-partum. These characteristics were included in the prognostic model for chronic hypertension. Model performance was good as indicated by good calibration and good discrimination (AUC; 0.83 (95% CI 0.75 - 0.92). Chronic hypertension can be expected from patient characteristics

Full Text Available Animal studies suggest that renal tissue hypoxia plays an important role in the development of renal damage in hypertension and renal diseases, yet human data were scarce due to the lack of noninvasive methods. Over the last decade, blood oxygenation level-dependent magnetic resonance imaging (BOLD-MRI, detecting deoxyhemoglobin in hypoxic renal tissue, has become a powerful tool to assess kidney oxygenation noninvasively in humans. This paper provides an overview of BOLD-MRI studies performed in patients suffering from essential hypertension or chronic kidney disease (CKD. In line with animal studies, acute changes in cortical and medullary oxygenation have been observed after the administration of medication (furosemide, blockers of the renin-angiotensin system or alterations in sodium intake in these patient groups, underlining the important role of renal sodium handling in kidney oxygenation. In contrast, no BOLD-MRI studies have convincingly demonstrated that renal oxygenation is chronically reduced in essential hypertension or in CKD or chronically altered after long-term medication intake. More studies are required to clarify this discrepancy and to further unravel the role of renal oxygenation in the development and progression of essential hypertension and CKD in humans.

Childhood interstitial lung disease (chILD) comprises a wide heterogeneous group of rare parenchymal lung disorders associated with substantial morbidity and mortality. Pulmonary hypertension is a common comorbidity in adults with interstitial lung disease (ILD) and associated with poor survival. We aimed to systematically review the literature regarding the occurrence of pulmonary hypertension (PH) in chILD, its effect on prognosis and healthcare use, and its treatment in clinical practice. Searches of PubMed and EMBASE databases (up to February 2016), and American Thoracic Society conference abstracts (2009-2015) were conducted using relevant keywords. References from selected articles and review papers were scanned to identify further relevant articles. A total of 20 articles were included; estimates of PH in chILD ranged from 1% to 64% with estimates among specific chILD entities ranging from 0% to 43%. Comparisons between studies were limited by differences in the study populations, including the size, age range, and heterogeneous composition of the ILD case series in terms of the nature and severity of the clinical entities, and also the methods used to diagnose PH. Three studies found that among patients with chILD, those with PH had a significantly higher risk (up to sevenfold) of death compared with those without PH. Information on the treatment of pulmonary hypertension in chILD or the effect of PH on healthcare use was not available. Data on the use and effectiveness of treatments for pulmonary hypertension in chILD are required to address this area of unmet need.

Full Text Available Hypertension in newborn infants, particularly those requiring intensive care, is becoming increasingly recognized, with prevalence of 0.2-3%. Recent studies have established normative tables for blood pressure (BP in both term and pre-term infants based on the gestational age, postnatal age, gender, weight and height, identifying the neonates at increased risk for early-onset cardiovascular disease. Common causes of neonatal hypertension include thromboembolic complications secondary to umbilical artery catheterization, congenital renal structural malformation, renovascular disease, aortic coarctation, as well as acute kidney injury and certain medications. A careful diagnostic evaluation should lead to identification of the underlying cause of hypertension in most infants. Treatment options should be tailored to the severity; and underlying cause of hypertension, including intravenous and/or oral therapy. This review summarizes recent work in these areas, focusing on optimal BP measurement, definition, evaluation and management of hypertension as well as advances in drug therapy of neonatal hypertension.

Resistant Hypertension.

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.

Full Text Available Discussion continues as to whether de novo hypertension in pregnancy with significant proteinuria (pre-eclampsia; PE and non-proteinuric new hypertension (gestational hypertension; GH are parts of the same disease spectrum or represent different conditions. Non-pregnant hypertension, pregnancy and PE are all associated with oxidative stress. We have established a 6 weeks post-partum clinic for women who experienced a hypertensive pregnancy. We hypothesized that PE and GH could be distinguished by markers of oxidative stress; thiobarbituric acid reactive substances (TBARS and antioxidants (ferric ion reducing ability of plasma; FRAP. Since the severity of PE and GH is greater pre-term, we also compared pre-term and term disease. Fifty-eight women had term PE, 23 pre-term PE, 60 had term GH and 6 pre-term GH, 11 pre-existing (essential hypertension (EH without PE. Limited data were available from normotensive pregnancies (n=7 and non-pregnant controls (n=14. There were no differences in postpartum TBARS or FRAP between hypertensive states; TBARS (P=0.001 and FRAP (P=0.009 were lower in plasma of non-pregnant controls compared to recently-pregnant women. Interestingly FRAP was higher in preterm than term GH (P=0.013. In PE and GH, TBARS correlated with low density lipoprotein (LDL-cholesterol (P=0.036; this association strengthened with inclusion of EH ((P=0.011. The 10 year Framingham index for cardiovascular risk was positively associated with TBARS (P=0.003.Oxidative stress profiles do not differ between hypertensive states but appear to distinguish between recently-pregnant and non-pregnant states. This suggests that pregnancy may alter vascular integrity with changes remaining 6 weeks postpartum. LDL-cholesterol is a known determinant of oxidative stress in cardiovascular disease and we have shown this association to be present in hypertensive pregnancy further emphasizing that such a pregnancy may be revealing a pre-existing cardiovascular

All the pregnantwomen underwent assessment of risk factors for AH, double measurement of office blood pressure, 24-hour blood pressure monitoring, electrocardiography, carotid ultrasonography, a microalbumin urine test, and eyeground examination. The pattern of AH was specified 12 weeks after childbirth.Results. Chronic AH – hypertensive disease – was diagnosed in 51 % of the examined pregnant women with AH. There was a considerable spread of risk factors for AH in this patient group. 26 % of them were found to have lesions of target organs (heart and/or arterial vessels; the rate of microalbuminuria registration was 41 %.Conclusion. Among our examined group of pregnant patients with AH, the prevalence of hypertensive disease is 51 %. In the identified patientgroup, cardiac and arterial vascular changes that could be considered as target organ lesions were found in almost a third of cases. Pregnant women with AH need to be meticulously examined and followed up by a therapist and a cardiologist in the postpartum period.

Celiac disease as a potential cause of idiopathic portal hypertension: a case report

Directory of Open Access Journals (Sweden)

Zamani Farhad

2009-02-01

Full Text Available Abstract Introduction Idiopathic portal hypertension is a disorder of unknown etiology, clinically characterized by portal hypertension, splenomegaly and anemia secondary to hypersplenism. Case presentation A 54-year-old man was admitted to our hospital for evaluation of malaise, weight loss, abdominal swelling and lower limb edema. His paraclinical tests revealed pancytopenia, large ascites, splenomegaly and esophageal varices consistent with portal hypertension. Duodenal biopsy and serologic findings were compatible with celiac disease. His symptoms improved on a gluten-free diet, but his clinical course was further complicated with ulcerative jejunoileitis, and intestinal T-cell lymphoma. Conclusion It seems that celiac disease, by an increased immune reaction in the splenoportal axis, can result in the development of idiopathic portal hypertension in susceptible affected patients.

Worse renal disease in postmenopausal F2[Dahl S x R]-intercross rats: detection of novel QTLs affecting hypertensive kidney disease.

Directory of Open Access Journals (Sweden)

Victoria L M Herrera

Full Text Available The prevalence of hypertension increases after menopause with 75% of postmenopausal women developing hypertension in the United States, along with hypertensive end organ diseases. While human and animal model studies have indicated a protective role for estrogen against cardiovascular disease and glomerulosclerosis, clinical studies of hormone replacement therapy in postmenopausal women have shown polar results with some improvement in hypertension but worsening of hypertensive kidney disease, or no effect at all. These observations suggest that the pathogenesis of postmenopausal hypertension and its target organ complications is more complex than projected, and that loss of endogenous estrogens induces epigenetic changes that alter genetic susceptibility to end-organ complications per se resulting in pathogenetic mechanisms beyond correction by hormone replacement. We studied postmenopausal-induced changes in renal disease and performed a total genome scan for quantitative trait loci (QTLs affecting kidney disease in postmenopausal 16m-old F2[Dahl S x R]-intercross female rats. We used glomerular injury score (GIS as quantitative trait. We compared QTLs amongst premenopausal, ovariectomized and postmenopausal F2[Dahl S x R]-intercross rats using identical phenotype characterization. Postmenopausal F2[Dahl S x R]-intercross rats exhibited increased hypertensive glomerulosclerosis (P<0.01 and equivalent levels of kidney disease when compared to premenopausal and ovariectomized F2[Dahl S x R]-intercross rats respectively.

Pulmonary hypertension is common in patients with chronic kidney disease (CKD) and end-stage renal disease (ESRD) and may be associated with poor outcomes. The magnitude of the association between pulmonary hypertension and mortality is uncertain due to the small size and variable findings of observational studies. Systematic review and meta-analysis of observational studies using subgroup analyses and metaregression. Patients with ESRD or earlier stages of CKD. Observational studies reporting clinical outcomes in patients with co-existing pulmonary hypertension and CKD or ESRD identified using a systematic search of PubMed and Embase. Pulmonary hypertension diagnosed by Doppler echocardiography. All-cause mortality, cardiovascular mortality, and cardiovascular events. 16 studies, with 7,112 patients with an overall pulmonary hypertension prevalence of 23%, were included. Pulmonary hypertension was associated with increased risk for all-cause mortality among patients with CKD (relative risk [RR], 1.44; 95% CI, 1.17-1.76), with ESRD receiving maintenance dialysis (RR, 2.32; 95% CI, 1.91-2.83), and with a functioning kidney transplant (RR, 2.08; 95% CI, 1.35-3.20). Pulmonary hypertension was associated with increased risk for cardiovascular events in patients with CKD (RR, 1.67; 95% CI, 1.07-2.60) and ESRD receiving dialysis (RR, 2.33; 95% CI, 1.76-3.08). There was an association between pulmonary hypertension and increased risk for cardiovascular mortality in patients with CKD or ESRD (RR, 2.20; 95% CI, 1.53-3.15). Heterogeneity of included studies, possibility of residual confounding, unavailability of individual patient-level data, and possibility of outcome reporting bias. Pulmonary hypertension is associated with a substantially increased risk for death and cardiovascular events in patients with CKD and ESRD. Risk is higher in patients with ESRD receiving dialysis compared with patients with CKD stages 1 to 5. Understanding the effect of interventions to lower

Resistant and Refractory Hypertension: Antihypertensive Treatment Resistance vs Treatment Failure

Science.gov (United States)

Siddiqui, Mohammed; Dudenbostel, Tanja; Calhoun, David A.

2017-01-01

Resistant or difficult to treat hypertension is defined as high blood pressure that remains uncontrolled with 3 or more different antihypertensive medications, including a diuretic. Recent definitions also include controlled blood pressure with use of 4 or more medications as also being resistant to treatment. Recently, refractory hypertension, an extreme phenotype of antihypertensive treatment failure has been defined as hypertension uncontrolled with use of 5 or more antihypertensive agents, including a long-acting thiazide diuretic and a mineralocorticoid receptor antagonist. Patients with resistant vs refractory hypertension share similar characteristics and comorbidities, including obesity, African American race, female sex, diabetes, coronary heart disease, chronic kidney disease, and obstructive sleep apnea. Patients with refractory vs resistant hypertension tend to be younger and are more likely to have been diagnosed with congestive heart failure. Refractory hypertension might also differ from resistant hypertension in terms of underlying cause. Preliminary evidence suggests that refractory hypertension is more likely to be neurogenic in etiology (ie, heightened sympathetic tone), vs a volume-dependent hypertension that is more characteristic of resistant hypertension in general.

Pulmonary arterial hypertension is a common complication of congenital heart disease (CHD). Congenital cardiopathies are the most frequent congenital malformations. The prevalence in our country remains unknown, based on birthrate, it is calculated that 12,000 to 16,000 infants in our country have some cardiac malformation. In patients with an uncorrected left-to-right shunt, increased pulmonary pressure leads to vascular remodeling and endothelial dysfunction secondary to an imbalance in vasoactive mediators which promotes vasoconstriction, inflammation, thrombosis, cell proliferation, impaired apotosis and fibrosis. The progressive rise in pulmonary vascular resistance and increased pressures in the right heart provocated reversal of the shunt may arise with the development of Eisenmenger' syndrome the most advanced form de Pulmonary arterial hypertension associated with congenital heart disease. The prevalence of Pulmonary arterial hypertension associated with CHD has fallen in developed countries in recent years that is not yet achieved in developing countries therefore diagnosed late as lack of hospital infrastructure and human resources for the care of patients with CHD. With the development of targeted medical treatments for pulmonary arterial hypertension, the concept of a combined medical and interventional/surgical approach for patients with Pulmonary arterial hypertension associated with CHD is a reality. We need to know the pathophysiological factors involved as well as a careful evaluation to determine the best therapeutic strategy. Copyright © 2014 Instituto Nacional de Cardiología Ignacio Chávez.

Estrogen exposure, obesity and thyroid disease in women with severe pulmonary hypertension

Directory of Open Access Journals (Sweden)

Sweeney Lori

2009-09-01

Full Text Available Abstract Severe pulmonary hypertension is a lethal group of disorders which preferentially afflicts women. It appears that in recent years the patient profile has shifted towards older, obese, and postmenopausal women, suggesting that endocrine factors may be important. Several studies have revealed an increased prevalence of thyroid disease in these patients, but no studies have evaluated for a coexistence of endocrine factors. In particular, no studies have attempted to evaluate for concurrent thyroid disease, obesity and long-term estrogen exposure in patients. 88 patients attending the Pulmonary Hypertension Association 8th International meeting completed a questionnaire and were interviewed. Information was collected regarding reproductive history, height, weight, and previous diagnosis of thyroid disease. 46% met criteria for obesity. 41% reported a diagnosis of thyroid disease. 81% of women reported prior use of hormone therapy. 70% reported greater than 10 years of exogenous hormone use. 74% of female patients reported two or more of potentially disease modifying endocrine factors (obesity, thyroid disease or estrogen therapy. The coexistent high prevalence in our cohort of exogenous estrogen exposure, thyroid disease and obesity suggests that an interaction of multiple endocrine factors might contribute to the pathogenesis of pulmonary hypertension and may represent epigenetic modifiers in genetically-susceptible individuals.

There is a significant disparity in hypertensive treatment rates between those with and without health insurance. If left untreated, hypertension leads to significant morbidity and mortality. The uninsured face numerous barriers to access chronic disease care. We developed the Community-based Chronic Disease Management (CCDM) clinics specifically for the uninsured with hypertension utilizing nurse-led teams, community-based locations, and evidence-based clinical protocols. All services, including laboratory and medications, are provided on-site and free of charge. In order to ascertain if the CCDM model of care was as effective as traditional models of care in achieving blood pressure goals, we compared CCDM clinics' hypertensive care outcomes with 2 traditional fee-for-service physician-led clinics. All the clinics are located near one another in poor urban neighborhoods of Milwaukee, Wisconsin. Patients seen at the CCDM clinics and at 1 of the 2 traditional clinics showed a statistically significant improvement in reaching blood pressure goal at 6 months (P fee-for-service clinics when compared with the CCDM clinics. The CCDM model of care is at least as effective in controlling hypertension as more traditional fee-for-service models caring for the same population. The CCDM model of care to treat hypertension may offer another approach for engaging the urban poor in chronic disease care. © The Author(s) 2016.

SECONDARY (ENDOCRINE HYPERTENSION: LECTURE

2016-01-01

Full Text Available Hypertension is a  very common disease with high morbidity and reduction in quality of life. Endocrine disorders are the most common cause of secondary hypertension affecting ~3% of the population. Primary aldosteronism can be the cause of endocrine hypertension more often than other endocrine disorders. Other less common causes of endocrine hypertension include Cushing syndrome, pheochromocytoma, thyroid disorders, and hyperparathyroidism. Endocrine hypertension is potentially curable if the underlying cause is identified and treated accordingly. Younger age at manifestation of resistance to multiple antihypertensive drugs, together with other clinical signs of an endocrine disorder, should raise the suspicion and prompt the appropriate evaluation.

The prevalence of and factors associated with uncontrolled hypertension and apparent resistant hypertension were assessed in the European Study on Cardiovascular Risk Prevention and Management in Usual Daily Practice (EURIKA; NCT00882336). EURIKA was a cross-sectional observational study including patients being treated for the primary prevention of cardiovascular disease in 12 European countries. Patients were assessed if they were being treated for hypertension (N=5220). Blood pressure control was defined according to European guidelines, with sensitivity analysis taking account of patients' age and diabetes status. Associated factors were assessed using multivariate analysis. In the primary analysis, a total of 2691 patients (51.6%) had uncontrolled hypertension. Factors significantly associated with an increased risk of having uncontrolled hypertension included female sex (odds ratio [OR]: 2.29; 95% confidence interval [CI]: 1.93-2.73), body mass index (BMI; OR per kg/m(2): 1.03; 95% CI: 1.01-1.04), and geographic location. A total of 749 patients (14.3%) had apparent resistant hypertension. Factors significantly associated with an increased risk of having apparent resistant hypertension included BMI (OR per kg/m(2): 1.06; 95% CI: 1.04-1.08), diabetes (OR: 1.28; 95% CI: 1.06-1.53), use of statins (OR: 1.36; 95% CI: 1.15-1.62), serum uric acid levels (OR: 1.16; 95% CI: 1.09-1.23), and geographic location. Similar results were seen in sensitivity analyses. Over 50% of patients treated for hypertension continued to have uncontrolled blood pressure and 14.3% had apparent resistant hypertension. Positive associations were seen with other cardiovascular risk factors. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Recognition and treatment of secondary causes of hypertension among patients with resistant hypertension may help to control blood pressure and reduce cardiovascular risk. However, there are no studies systematically evaluating secondary causes of hypertension according to the Seventh Joint National Committee. Consecutive patients with resistant hypertension were investigated for known causes of hypertension irrespective of symptoms and signs, including aortic coarctation, Cushing syndrome, obstructive sleep apnea, drugs, pheochromocytoma, primary aldosteronism, renal parenchymal disease, renovascular hypertension, and thyroid disorders. Among 125 patients (age: 52±1 years, 43% males, systolic and diastolic blood pressure: 176±31 and 107±19 mm Hg, respectively), obstructive sleep apnea (apnea-hypopnea index: >15 events per hour) was the most common condition associated with resistant hypertension (64.0%), followed by primary aldosteronism (5.6%), renal artery stenosis (2.4%), renal parenchymal disease (1.6%), oral contraceptives (1.6%), and thyroid disorders (0.8%). In 34.4%, no secondary cause of hypertension was identified (primary hypertension). Two concomitant secondary causes of hypertension were found in 6.4% of patients. Age >50 years (odds ratio: 5.2 [95% CI: 1.9-14.2]; Phypertension. Age >50 years, large neck circumference measurement, and snoring are good predictors of obstructive sleep apnea in this population.

In Brazil hypertension and type 2 diabetes mellitus are responsible for 60% of cases of end-stage renal disease in renal replacement therapy. In the United States studies have identified family clustering of chronic kidney disease, predominantly in African-Americans. A single Brazilian study observed family clustering among patients with chronic kidney disease when compared with hospitalized patients with normal renal function. This article aims to assess whether there is family clustering of chronic kidney disease in relatives of individuals in renal replacement therapy caused by hypertension and/or diabetes mellitus. A case-control study with 336 patients in renal replacement therapy with diabetes mellitus or hypertension for at least 5 years (cases) and a control matched sample group of individuals with hypertension or diabetes mellitus and normal renal function (n = 389). Individuals in renal replacement therapy (cases) had a ratio of 2.35 (95% CI 1.42-3.89, p hypertension or diabetes mellitus).

Nodular Regenerative Hyperplasia and Portal Hypertension in a Patient with Coeliac Disease

Full Text Available Nodular regenerative hyperplasia (NRH of the liver is often associated with rheumatologic or lymphoproliferative disorders and a cause of portal hypertension in some patients. We report the case of a 71-year-old patient with celiac disease and unexplained portal hypertension. Biopsy of the liver revealed NRH as the underlying cause. The patient did not suffer from an autoimmune, rheumatologic or lymphoproliferative disease. A thrombophilic disorder that might cause NRH was ruled out. Celiac disease is often associated with mild elevation of liver enzymes and steatosis of the liver, but the association with NRH was described in only a few patients. We discuss the possible relationship of celiac disease and NRH.

The objective of this study is to evaluate a woman's risk perception for future cardiovascular disease (CVD) after being diagnosed with a hypertensive disorder of pregnancy. A prospective cohort of women diagnosed with a hypertensive disorder of pregnancy (HDP) was studied. Each woman completed two surveys, one prior to hospital discharge and one 2 weeks later, designed to assess knowledge of and risk perception for future CVD based on their recent diagnosis of a HDP. Rates of postpartum depression were also assessed. Of the 146 subjects included, 28% were diagnosed with preeclampsia with severe features, 52.1% with preeclampsia with mild features, and 19.9% had chronic hypertension. Women with severe features and those delivering preterm were more likely to report a perception of increased risk of both recurrent HDP in a future pregnancy (p = 0.004 and 0.005, respectively) and hypertension later in life (p = 0.01 and 0.03, respectively). Women delivering preterm were more likely to report an accurate perception of increased risk of myocardial infarction and stroke compared to those delivering at term (p = 0.006 and 0.002, respectively). Disease severity and preterm delivery were associated with a higher likelihood of the perception of an increased risk for both recurrent HDP and hypertension in the future. Only preterm delivery was associated with a higher risk perception for stroke and myocardial infarction. Interventions targeted at improved health awareness in women diagnosed with HDP are warranted.

To study causes of vertigo in hypertensive patients and specify approaches to its treatment. Material and methods. Prevalence and causes of vertigo were analysed in 285 patients with arterial hypertension (AH). The examination included 24-h monitoring of arterial pressure (APM) and MR-tomography of the head. The majority of patients (78%) hospitalized with the diagnosis "hypertensive crisis" were diagnosed to have other diseases (headaches of tension, stroke, Meniere's syndrome and disease, etc.) the development of which was accompanied with hypertension and simulated a hypertensive crisis. Vertigo occurs in 20% hypertensive patients and is unrelated to elevated blood pressure. It is rather due to associated neurological, peripheral vestibular and other diseases. APM shows that vertigo occurs in hypotension after intake of hypotensive drugs. In hypertensive patients treatment of vertigo should not be directed only to management of elevated pressure but demands treatment of underlying disease. Vertigo plus mnestic disorders are effectively corrected with tanakan in a dose 120-160 mg/day. Vertigo in hypertensive patients is not caused by elevated pressure but related with concomitant neurological or peripheral vestibular diseases as well as hypotension. Hypertensive patients with vertigo need correction of the condition causing it.

Cardiovascular diseases are the leading cause of death and disability in the elderly. In this study, healthy eating habits and associated factors in the prevention of cardiovascular disease in elderly hypertensive individuals were identified. It involved a cross-sectional study gathering primary data in a family health unit in a city in the interior of the state of Rio Grande do Sul and 212 elderly hypertensive individuals participated in the study. A higher prevalence among the lower age bracket of elderly individuals, female, with little schooling and low income was revealed. Healthy eating habits among the elderly hypertensive individuals assessed are below those recommended in the prevention of cardiovascular disease. Social and economic factors, health characteristics and the use of health services influenced the adoption of healthy eating habits. The results of this study suggest that elderly hypertensive individuals find it difficult to adopt healthy eating habits. This contributes further to the definition of strategies for routine prevention and control of cardiovascular diseases in the elderly.

Background: Globally, obesity is now recognised as an epidemic. The degree of obesity is proportional to the rate of development of cardiovascular diseases, hence, resulting in a dramatic increase in morbidity and mortality. Apart from obesity, hypertension is another well recognised risk factor contributing to coronary artery disease (CAD). The precise prevalence of obesity-related hypertension varies with age, race and gender; and is yet unknown in our population. The objective of this study was to determine the prevalence of hypertension in obese and non-obese patients with diagnosed CAD. Methods: This hospital based descriptive study was conducted in Cardiology Department of Postgraduate Medical Institute, Lady Reading Hospital, Peshawar from March 15, 2007 to May 30, 2008. A total of 200 patients with diagnosed CAD were enrolled, 100 were found obese and 100 non-obese. Results: Among these, a total of 111 (55.5%) were found to be hypertensive, 66 (59.46%) of these were obese and 45 (40.54%) non-obese (p=0.003). Conclusion: Obese patients with CAD had significantly more frequent hypertension. (author)

2010-01-01

Severe pulmonary hypertension in a teenager with end-stage renal disease on chronic hemodialysis via arteriovenous access is reported. Clinical presentation included persistent volume overload and pericardial effusion. Serial hemodynamic data obtained at cardiac catheterization confirmed the diagnosis. In addition, detailed biochemical and imaging data (echo- Doppler, computed tomography of chest, computed tomographic pulmonary angiography, VQ lung scan, etc.) were obtained to find out the mechanism. The exact cause of pulmonary hypertension remains unclear, and a multi- factorial mechanism is postulated. This rare case is presented to highlight the role of aggressive dialysis, pericardiocentesis, and use of sildenafil and bosentan in the management

Pulmonary arterial hypertension in congenital heart disease: Correlation of radiologic index with hemodynamic data

Choi, Young Hi

1984-01-01

It is well known that pulmonary arterial hypertension in congenital heart disease is an important prognostic factor, as is pulmonary vascular resistance. So it is tempting to get certain radiologic index that could predict the presence and the degree of pulmonary arterial hypertension. A total of 152 cases of left to right shunt with pulmonary arterial hypertension and 50 cases of left to right shunt without pulmonary arterial hypertension is presented, in which cardiac catheterization and angiocardiography were done at the Department of Radiology, Seoul National University Hospital between March 1981 and February 1983. Statistical analysis of plain radiography findings with the emphasis on the correction of radiologic index with the hemodynamic data. The results are as follows: 1. The incidence of pulmonary arterial hypertension is much less in arterial septal defect than other two disease groups of left to right shunt. 2. PA/T ratio correlates well with pulmonary arterial pressure (r=0.674), especially in mild pulmonary hypertension group. No correlation in moderate pulmonary hypertension group in significant level. 3. PA/T ratio is below 38 in total cases of normal control group and in 32 cases (21.0%) among 152 cases of pulmonary arterial hypertension group. 4. The average PA/T ratio in normal pressure group of left to right shunt is 35.3, which has no significant difference from that of normal control group. 5. The average CT ratio of pulmonary arterial hypertension group is 59.0, which is larger than 49.1 of normal control group. The CT ratio shows no correlation with the pulmonary arterial pressure in statistically significant level. 6. The higher the pulmonary arterial pressure, the larger the Rp/Rs value. The Rp/Rs in atrial septal defect is 0.193 in average, the lowest value in comparison with other two disease groups.

Full Text Available The aim of the study was to determine correlation between arterial blood pressure daily rhythm and daily profile of arterial stiffness in male patients with chronic obstructive pulmonary disease (COPD and arterial hypertension. Materials et methods: Prospective investigation comprised 45 male patients with COPD and arterial hypertension. Individuals of 40 years younger and 80 years elder, patients with diabetes, stroke, angina pectoris, or heart infarction, vascular diseases, and exacerbation of chronic disease, bronchial and pulmonary diseases of other etiology were excluded from the analyses. Comparison group included 47 patients with essential arterial hypertension and without chronic respiratory diseases closely similar on general parameters with patients from main clinical series. Twenty-four-hour arterial blood pressure monitoring (ABPM and daily arterial stiffness monitoring were performed using BPLab® MnSDP-2 apparatus (Petr Telegin, Russian Federation. Results: Patients with COPD combined with arterial hypertension with raised arterial stiffness measures prevail over individuals in essential hypertension group. There is pathological alteration of the ABPM circadian rhythm and raised «Pressure load» values in raised arterial stiffness group. Conclusion: We found ABPM raised parameters in patients with COPD and arterial hypertension. It confirms necessity of ABPM in daily arterial stiffness assessment in patients with COPD.

The possibility of developing idiopathic portal hypertension has been described with thiopurine treatment despite compromises the prognosis of these patients, the fact its true prevalence is unknown. A cross-sectional study was conducted in a cohort of inflammatory bowel disease (IBD) patients followed at our unit, to determine the prevalence of diagnosis of idiopathic portal hypertension (IPH) and its relationship with thiopurine treatment. At the time of the analysis, 927/1,419 patients were under treatment with thiopurine drugs (65%). A total of 4 patients with IBD type Crohn's disease with idiopathic portal hypertension probably related to the thiopurine treatment were identified (incidence of 4.3 cases per 1,000). Seventy-five percent of patients started with signs or symptoms of portal hypertension. Only one patient was asymptomatic but the diagnosis of IPH because of isolated thrombocytopenia is suspected. However, note that all patients had thrombocytopenia previously. Abdominal ultrasound with fibroscan, hepatic vein catheterization and liver biopsy were performed on all of them as part of the etiology of portal hypertension. In the abdominal ultrasound, indirect portal hypertension data were observed in all patients (as splenomegaly) cirrhosis was also ruled out. The fibroscan data showed significant liver fibrosis (F2-F3). Idiopathic portal hypertension following thiopurine treatment in IBD patients is a rare occurrence, but it must be borne in mind in the differential diagnosis for early diagnosis, especially in patients undergoing thiopurine treatment over a long period. The presence of thrombocytopenia is often the only predictor of its development in the preclinical stage.

Drug-induced valvular heart disease (DI-VHD) remains an under-recognized entity. This report describes a heart valve replacement which was complicated by intractable systemic pulmonary arterial hypertension in a 61-year-old female with severe restrictive mitral and aortic disease. The diagnosis of valvular disease was preceded by a history of unexplained respiratory distress. The patient had been exposed to benfluorex for 6.5 years. The diagnostic procedure documented specific drug-induced valvular fibrosis. Surgical mitral and aortic valve replacement was performed. Heart valve replacement was postoperatively complicated by unanticipated disproportionate pulmonary hypertension. This issue was fatal despite intensive care including prolonged extracorporeal life support. Benfluorex is a fenfluramine derivative which has been marketed between 1976 and 2009. Although norfenfluramine is the common active and toxic metabolite of all fenfluramine derivatives, the valvular and pulmonary arterial toxicity of benfluorex was much less known than that of fenfluramine and dexfenfluramine. The vast majority of benfluorex-induced valvular heart disease remains misdiagnosed as hypothetical rheumatic fever due to similarities between both etiologies. Better recognition of DI-VHD is likely to improve patient outcome.

Dynamic computed tomography was conducted by the original methods; the findings were analyzed by taking into account time-density curves which made it possible to gain an insight into the status of blood flow and filtration in each individual kidney. Computed tomography and dynamic computed tomography revealed that hypertensive disease was characterized by normal volume and thickness of the renal cortical layer and symmetric time-density curves, whereas a hypertensive type of chronic glomerulonephritis featured lower renal cartical layer thickness, reduced renal volume, symmetrically decrease amplitudes of the first and second peaks of the time-density curve, chronic pyelonephritis showed asymmetric time-density diagrams due to the lower density areas in the afflicted kidney

Comparison among patients with hypertrophic cardiomyopathy, hypertrophic cardiomyopathy with hypertension and hypertensive heart disease by 123I-BMIPP myocardial scintigraphy

Yoneyama, Satoshi; Sugihara, Hiroki; Ito, Kazuki

1997-01-01

The usefulness of 123 I-BMIPP myocardial SPECT in discriminating hypertrophic cardiomyopathy (46 patients), hypertrophic cardiomyopathy with hypertension (23 patients), and hypertensive hypertrophic heart (20 patients) was studied. SPECT image was divided into 17 domains, and dimension of decreased accumulation was decided visually at each domain as four classes called defect score (DS). Summation of DS (TDS) of each group was used to compare frequency and dimension of decreased accumulation, and characteristic of each site. Frequency of decreased accumulation and TDS in hypertrophic cardiomyopathy were similar in dimension with those in hypertrophic cardiomyopathy with hypertension, and those data in hypertensive hypertrophic heart were lower than those in above-mentioned 2 groups. In the cases of hypertrophic cardiomyopathy and hypertrophic cardiomyopathy with hypertension, decreased accumulation site was similar and was anterior wall-septum junction, septum-posterior wall junction and apex of heart. In the case of hypertensive hypertrophic heart, decreased accumulation site was only the posterior wall. Frequency, dimension and site of decreased accumulation in hypertrophic cardiomyopathy were different from those in hypertensive hypertrophic heart, and BMIPP was thought to be useful in discriminating these diseases.

Addison's disease presenting with idiopathic intracranial hypertension in 24-year-old woman: a case report

2010-02-01

Full Text Available Abstract Introduction Idiopathic intracranial hypertension can rarely be associated with an underlying endocrine disorder such as Cushing's syndrome, hyperthyroidism, or with administration of thyroxine or growth hormone. Though cases of idiopathic intracranial hypertension associated with Addison's disease in children have been reported, there is only one documented case report of this association in adults. We describe a case of an acute adrenal insufficiency precipitated by idiopathic intracranial hypertension in a Caucasian female. Case presentation A 24-year-old Caucasian woman was acutely unwell with a background of several months of generalised fatigue and intermittent headaches. She had unremarkable neurological and systemic examination with a normal computerised tomography and magnetic resonance imaging of the brain. Normal cerebrospinal fluid but increased opening pressure at lumbar puncture suggested intracranial hypertension. A flat short synacthen test and raised level of adrenocorticotrophic hormone were consistent with primary adrenal failure. Conclusion Addison's disease can remain unrecognised until precipitated by acute stress. This case suggests that idiopathic intracranial hypertension can rarely be associated with Addison's disease and present as an acute illness. Idiopathic intracranial hypertension is possibly related to an increase in the levels of arginine vasopressin peptide in serum and cerebrospinal fluid secondary to a glucocorticoid deficient state.

Arterial hypertension is the most common chronic disease in developed countries and it is the leading risk factor for stroke, ischemic heart disease, congestive heart failure, chronic renal failure and peripheral artery disease. Its prevalence appears to be about 30-45% of the general population. Recent European guidelines estimate that up to 15-20% of the hypertensive patients are not controlled on a dual antihypertensive combination and they require three or more different antihypertensive drug classes to achieve adequate blood pressure control. The guidelines confirmed that diuretics, beta-blockers, calcium-channel blockers, angiotensin-converting enzyme inhibitors and angiotensin receptor blockers are suitable for the initiation and maintenance of antihypertensive treatment, either as monotherapy or in combination therapy. Very few antihypertensive agents have reached the market over the last few years, but no new therapeutic class has really emerged. The long-term adherence to cardiovascular drugs is still low in both primary and secondary prevention of cardiovascular diseases. In particular, the issue of compliance is persistently high in hypertension, despite the fixed-dose combination therapy. As a consequence, a cohort of high-risk hypertensive population, represented by patients affected by refractory and resistant hypertension, can be identified. Therefore, the need of controlling BP in high-risk patients may be addressed, in part, by the development of new drugs, devices and procedures that are designed to treat hypertension and comorbidities. In this review we will comprehensively discuss the current literature on recent therapeutic advances in hypertension, including both medical therapy and interventional procedures.

1988-01-01

Four to 20% positive findings were found in a review of 1913 excretory urographics. Possibly relevant findings were 20% in patients referred for infectious disease, 10% in hypertensive disease, 6% in hematuria and 4% in neoplasms. Urography influenced treatment mainly in the 2 groups with few positive findings. The costs for positive findings may be acceptable in patients with hematuria or suspicion of neoplasms, but are too high in the other groups. Until ultrasonography can replace intravenous urography as the first screening method in upper urinary tract disease, the patient selection for urography in infectious and hypertensive disease should be improved.

Cardiovascular disease and hypertension in sub-Saharan Africa: burden, risk and interventions.

Science.gov (United States)

Cappuccio, Francesco Paolo; Miller, Michelle Avril

2016-04-01

Cardiovascular disease, including stroke, heart failure and kidney disease, has been common in sub-Saharan Africa for many years, and rapid urbanization is causing an upsurge of ischaemic heart disease and metabolic disorders. At least two-thirds of cardiovascular deaths now occur in low- and middle-income countries, bringing a double burden of disease to poor and developing world economies. High blood pressure (or hypertension) is by far the commonest underlying risk factor for cardiovascular disease. Its prevention, detection, treatment and control in sub-Saharan Africa are haphazard and suboptimal. This is due to a combination of lack of resources and health-care systems, non-existent effective preventive strategies at a population level, lack of sustainable drug therapy, and barriers to complete compliance with prescribed medications. The economic impact for loss of productive years of life and the need to divert scarce resources to tertiary care are substantial.

Pulmonary Hypertension and Right Heart Dysfunction in Chronic Lung Disease

Amirmasoud Zangiabadi

2014-01-01

Full Text Available Group 3 pulmonary hypertension (PH is a common complication of chronic lung disease (CLD, including chronic obstructive pulmonary disease (COPD, interstitial lung disease, and sleep-disordered breathing. Development of PH is associated with poor prognosis and may progress to right heart failure, however, in the majority of the patients with CLD, PH is mild to moderate and only a small number of patients develop severe PH. The pathophysiology of PH in CLD is multifactorial and includes hypoxic pulmonary vasoconstriction, pulmonary vascular remodeling, small vessel destruction, and fibrosis. The effects of PH on the right ventricle (RV range between early RV remodeling, hypertrophy, dilatation, and eventual failure with associated increased mortality. The golden standard for diagnosis of PH is right heart catheterization, however, evidence of PH can be appreciated on clinical examination, serology, radiological imaging, and Doppler echocardiography. Treatment of PH in CLD focuses on management of the underlying lung disorder and hypoxia. There is, however, limited evidence to suggest that PH-specific vasodilators such as phosphodiesterase-type 5 inhibitors, endothelin receptor antagonists, and prostanoids may have a role in the treatment of patients with CLD and moderate-to-severe PH.

Secondary Hypertension: Discovering the Underlying Cause.

Science.gov (United States)

Charles, Lesley; Triscott, Jean; Dobbs, Bonnie

2017-10-01

Most patients with hypertension have no clear etiology and are classified as having primary hypertension. However, 5% to 10% of these patients may have secondary hypertension, which indicates an underlying and potentially reversible cause. The prevalence and potential etiologies of secondary hypertension vary by age. The most common causes in children are renal parenchymal disease and coarctation of the aorta. In adults 65 years and older, atherosclerotic renal artery stenosis, renal failure, and hypothyroidism are common causes. Secondary hypertension should be considered in the presence of suggestive symptoms and signs, such as severe or resistant hypertension, age of onset younger than 30 years (especially before puberty), malignant or accelerated hypertension, and an acute rise in blood pressure from previously stable readings. Additionally, renovascular hypertension should be considered in patients with an increase in serum creatinine of at least 50% occurring within one week of initiating angiotensin-converting enzyme inhibitor or angiotensin receptor blocker therapy; severe hypertension and a unilateral smaller kidney or difference in kidney size greater than 1.5 cm; or recurrent flash pulmonary edema. Other underlying causes of secondary hypertension include hyperaldosteronism, obstructive sleep apnea, pheochromocytoma, Cushing syndrome, thyroid disease, coarctation of the aorta, and use of certain medications.

The publication of the first non-randomised proof-of-concept trial of renal denervation as a treatment modality in treatment-resistant hypertension set the stage for a search for novel devices with the expectation that technology would reduce the burden of hypertension by reducing or eliminating the costly and lifelong use of blood pressure lowering medications. As we demonstrate in this review, this idea so attractive to manufacturers and invasive cardiologists and radiologists overlooked decades of careful pathophysiological research in a disease, which still remains enigmatic but remains the major cause of cardiovascular mortality worldwide. To make our point, we first reviewed the prevalence and risks associated with treatment-resistant hypertension. Next, we highlighted the key points required for the diagnosis of treatment-resistant hypertension, including the recording of the ambulatory blood pressure and the assessment of adherence to medication. Finally, we summarised new insights in the management of treatment-resistant hypertension by medication and devices and in the future research. Throughout our review, we focused on new evidence became available since 2013. Our conclusion is that optimising medical treatment based on simple algorithms remains the state of the art in treatment-resistant hypertension.

ABCC-JNIH Adult Health Study Hiroshima, 1958 to 1959. Hypertension and ischemic heart disease

Switzer, S

1963-11-12

The interrelations of hypertension, ischemic heart disease, blood lipid levels and ionizing irradiation were investigated among 1051 male and 1872 female members of the ABCC-JNIH Adult Health Study. No significant effect of ionizing irradiation upon the cardiovascular system were detected. No major difference in age-sex specific mean blood pressures between Adult Health Study subjects and a suitable American comparison group was found. An accelerated course with fulminating vascular deterioration was suspected in only 1% of the hypertensive subjects. As a result, advanced retinopathy and renal failure were rarely seen. Electrocardiographic evidence of left ventricular hypertrophy occurred in 7.2% of the hypertensive subjects in this study, and was readily correlated with ambient systolic blood pressure. Evidences of ischemic heart disease and congestive failure were rare and distinctly less common than in American males unselected as to blood pressure levels. In contrast, mortality statistics indicate cerebrovascular disease to be at least as common in Japan as in the United States. Adult Health Study data exhibit low serum cholesterol concentrations by Western standards and elevated levels are predominantly limited to the obese. Both factors appear of importance in the occasional hypertensive subject with ischemic heart disease. The therapeutic implication of this observation is briefly discussed. 57 references, 10 tables.

Full Text Available Hypertension is a common disorder with uncertain etiology. In the last several years, it has become evident that components of both the innate and adaptive immune system play an essential role in hypertension. Macrophages and T cells accumulate in the perivascular fat, the heart and the kidney of hypertensive patients and in animals with experimental hypertension. Various immunosuppressive agents lower blood pressure and prevent end-organ damage. Mice lacking lymphocytes are protected against hypertension, and adoptive transfer of T cells, but not B cells in the animals restores their blood pressure response to stimuli such as angiotensin II or high salt. Recent studies have shown that mice lacking macrophages have blunted hypertension in response to angiotensin II and that genetic deletion of macrophages markedly reduces experimental hypertension. Dendritic cells have also been implicated in this disease. Many hypertensive stimuli have triggering effects on the central nervous system and signals arising from the circumventricular organ seem to promote inflammation. Studies have suggested that central signals activate macrophages and T cells, which home to the kidney and vasculature and release cytokines, including IL-6 and IL-17, which in turn cause renal and vascular dysfunction and lead to blood pressure elevation. These recent discoveries provide a new understanding of hypertension and provide novel therapeutic opportunities for treatment of this serious disease.

BACKGROUND: In Nigeria, systemic hypertension is the commonest noncommunicable disease, and public awareness about hypertension and its determinants is poor. This study aims to assess the knowledge and level of awareness of the disease among hypertensive patients attending the medical outpatient clinic of Olabisi Onabanjo University Teaching Hospital (OOUTH). METHODOLOGY: Hypertensive patients who attended the medical outpatient clinic during the one-year study period and gave their consent were recruited into the study. Response to a questionnaire on various aspects of hypertension was analyzed using the STATA for Windows software. RESULTS: There were 254 hypertensive patients, of which 111 were males and 143 were females, giving a male: female ratio of 1:1.3. The mean age (SD) of the patients was 51 years +/- 12.2; 52.4% of the participants were aware that hypertension was the commonest noncommunicable disease in Nigeria. About one in 10 patients (11.4%) was aware that "nil symptom" is the commonest symptom of hypertension, while 37% were not aware that hypertension could cause renal failure. Only about one-third (35.4%) of the patients knew that hypertension should ideally be treated for life, while 58.3% believed that antihypertensive drugs should be used only when there are symptoms. The remaining 6.3% believed that the treatment of hypertension should be for periods ranging from two weeks to five years but not for life. CONCLUSION: This study has demonstrated inadequate knowledge of hypertension in patients with hypertension in our study population. Conscious efforts should be made and time set aside to health educate hypertensive patients. Organization of "hypertensive club or society" could be encouraged. These will reduce dissemination of false or inaccurate information by hypertensive patients to the public and its attendant dangers. PMID:15160976

Patients with combined post- and precapillary pulmonary hypertension due to left heart disease have a worse prognosis compared with isolated postcapillary. However, it remains unclear whether increased mortality in combined post- and precapillary pulmonary hypertension is simply a result of higher total right ventricular load. Pulmonary effective arterial elastance (Ea) is a measure of total right ventricular afterload, reflecting both resistive and pulsatile components. We aimed to test whether pulmonary Ea discriminates survivors from nonsurvivors in patients with pulmonary hypertension due to left heart disease and if it does so better than other hemodynamic parameters associated with combined post- and precapillary pulmonary hypertension. We combined 3 large heart failure patient cohorts (n=1036) from academic hospitals, including patients with pulmonary hypertension due to heart failure with preserved ejection fraction (n=232), reduced ejection fraction (n=335), and a mixed population (n=469). In unadjusted and 2 adjusted models, pulmonary Ea more robustly predicted mortality than pulmonary vascular resistance and the transpulmonary gradient. Along with pulmonary arterial compliance, pulmonary Ea remained predictive of survival in patients with normal pulmonary vascular resistance. The diastolic pulmonary gradient did not predict mortality. In addition, in a subset of patients with echocardiographic data, Ea and pulmonary arterial compliance were better discriminators of right ventricular dysfunction than the other parameters. Pulmonary Ea and pulmonary arterial compliance more consistently predicted mortality than pulmonary vascular resistance or transpulmonary gradient across a spectrum of left heart disease with pulmonary hypertension, including patients with heart failure with preserved ejection fraction, heart failure with reduced ejection fraction, and pulmonary hypertension with a normal pulmonary vascular resistance. © 2018 American Heart Association

Noncirrhotic portal hypertension represents a heterogeneous group of liver disorders that is characterized by portal hypertension in the absence of cirrhosis. The purpose of this review is to serve as a guide on how to approach a patient with noncirrhotic portal hypertension with a focus on recent developments. Recent studies pertaining to noncirrhotic portal hypertension have investigated aetiological causes, mechanisms of disease, noninvasive diagnostic modalities, clinical characteristics in the paediatric population and novel treatment targets. Noncirrhotic portal hypertension is an underappreciated clinical entity that can be difficult to diagnosis without a healthy suspicion. Diagnosis then relies on a comprehensive understanding of the causes and clinical manifestations of this disease, as well as a careful interpretation of the liver biopsy. Noninvasive approaches to diagnosis may play a significant role moving forward in this disease. Treatment in NCPH remains largely targeted at the individual sequalae of portal hypertension.

Pulmonary hypertension in chronic hemolytic anemias: Pathophysiology and treatment.

Haw, Alexandra; Palevsky, Harold I

2018-04-01

Pulmonary hypertension has emerged as a major cause of morbidity and mortality in patients with hemoglobinopathies and chronic hemolytic anemias. These hematological diseases include - but are not limited to - sickle cell disease (SCD), thalassemia, paroxysmal nocturnal hematuria, and hereditary spherocytosis. Although most studies have been based on the use of echocardiography as a screening tool for pulmonary hypertension as opposed to the gold standard of right heart catheterization for definitive diagnosis, the association between chronic hemolytic anemia and pulmonary hypertension is evident. Studies have shown that patients with SCD and a tricuspid regurgitant velocity (TRV) ≥ 2.5 m/sec are at increased risk of pulmonary hypertension and are at increased mortality risk. Additional markers of risk of pulmonary hypertension and increased mortality include a pro-BNP >160 pg/mL combined with a 6-min walk distance of pulmonary hypertension in chronic hemolytic anemias.

Do we over treat mild hypertension?

Science.gov (United States)

Zanchetti, Alberto

2015-06-01

The important question whether 'mild' hypertension should or should not be treated by drugs is difficult to answer, because the only randomized controlled trials (RCTs) investigating this question were conducted when the definition of 'mild' hypertension was based on diastolic blood pressure only, whereas the present definition of grade 1 hypertension includes both systolic and diastolic values (SBP/DBP), and the concept of 'mild' hypertension also includes that of low-moderate cardiovascular risk (hypertension only on the basis of expert opinion. However, recent meta-analyses have provided some support to drug treatment intervention in low-moderate risk grade 1 hypertensives and have shown that, when treatment is deferred until organ damage or cardiovascular disease occur, absolute residual risk (events occurring despite treatment) markedly increases. Although evidence favoring therapeutic intervention in mild hypertension is nowadays stronger than expert opinion, meta-analyses are not substitutes for specific RCTs, and the wide BP spans defining grade 1 hypertension as well as the span defining low-moderate risk leave a wide space for individualized or personalized decisions.

Full Text Available Idiopathic intracranial hypertension (IIH is a central nervous system disorder characterized by raised intracranial pressure with normal cerebrospinal fluid composition and absence of any structural anomaly on neuroimaging. Among all endocrine disorders associated with the development of IIH, the association of hyperthyroidism and IIH is very rare with few cases reported till date. Thyroid disturbances have a unique association with IIH. Hypo- and hyper-thyroidism have been reported in association with this disorder. We present a rare case of a 25-year-old man with Graves' disease with intractable headache that was later investigated and attributed to development of IIH.

Renal sympathetic denervation (RSD) is emerging as a new therapeutic option for patients with severe hypertension refractory to medical therapy. The presence of a renal artery stenosis may be both a cause of secondary hypertension and a contraindication to RSD if a renal artery stent is implanted; therefore, the definition of the functional importance of a renal artery stenosis in a patient with refractory hypertension is crucial. We describe the imaging and functional intravascular assessment of an angiographically severe stenosis of the renal artery in a patient with severe refractory hypertension, by means of intravascular ultrasound (IVUS), and measurement of the translesional pressure gradient with a pressure wire. Pressure wire examination excluded any severity of the stenosis, and IVUS showed the presence of a dissected plaque that resolved spontaneously after 3 months of intensive medical therapy and high-dose statin. Subsequently the patient was treated with RSD, achieving a significant effect on blood pressure control. Intravascular imaging and functional assessment of renal artery anatomy in patients with atherosclerotic disease may prove particularly suited to patients with refractory hypertension and multilevel vascular disease who are considered for endovascular therapies, either renal artery stenting or RSD.

The worldwide prevalence of obesity has nearly doubled, with an increase in obesity-related cardiovascular disease and mortality. Several factors are involved in the genesis of hypertension and hypertensive heart disease (HHD) in overweight/obesity. This review is focused on bridging factors between excessive adiposity and HHD, presenting a unifying hypothesis of vascular-metabolic syndrome, where an "handicap" of the natriuretic peptide system has a central role both in adipocyte dysmetabolism as well as in increased blood pressure and HHD.

Portal hypertension develops as a result of increased intrahepatic vascular resistance often caused by chronic liver disease that leads to structural distortion by fibrosis, microvascular thrombosis, dysfunction of liver sinusoidal endothelial cells (LSECs), and hepatic stellate cell (HSC) activation. While the basic mechanisms of LSEC and HSC dysregulation have been extensively studied, the role of microvascular thrombosis and platelet function in the pathogenesis of portal hypertension remains to be clearly characterized. As a secondary event, portal hypertension results in splanchnic and systemic arterial vasodilation, leading to the development of a hyperdynamic circulatory syndrome and subsequently to clinically devastating complications including gastroesophageal varices and variceal hemorrhage, hepatic encephalopathy from the formation of portosystemic shunts, ascites, and renal failure due to the hepatorenal syndrome. This review article discusses: (1) mechanisms of sinusoidal portal hypertension, focusing on HSC and LSEC biology, pathological angiogenesis, and the role of microvascular thrombosis and platelets, (2) the mesenteric vasculature in portal hypertension, and (3) future directions for vascular biology research in portal hypertension.

The conjoint association of gestational diabetes mellitus (GDM) and gestational hypertension (GH) with cardiometabolic disease has not been well studied. We evaluated a combined GDM/GH risk indicator in both mothers and fathers because of shared spousal behaviors and environments. In the present population-based retrospective cohort study, GH was identified in matched pairs of mothers with GDM or without GDM (matched on age group, health region, and year of delivery) who had singleton live births in Quebec, Canada (1990-2007). A total of 64,232 couples were categorized based on GDM/GH status (neither, either, or both). Associations with diabetes, hypertension, and a composite of cardiovascular disease (CVD) and mortality were evaluated using Cox proportional hazard models (from 12 weeks postpartum to March 2012). Compared with having neither GDM nor GH, having either was associated with incident diabetes (hazard ratio (HR) = 14.7, 95% confidence interval (CI): 12.9, 16.6), hypertension (HR = 1.9, 95% CI: 1.8, 2.0), and CVD/mortality (HR = 1.4, 95% CI: 1.2, 1.7). We found associations of greater magnitude among participants who had both (for diabetes, HR = 36.9, 95% CI: 26.0, 52.3; for hypertension, HR = 5.7, 95% CI: 4.9, 6.7; and for CVD/mortality, HR = 2.4, 95% CI: 1.6, 3.5). Associations with diabetes were also observed in fathers (for either, HR = 1.2, 95% CI: 1.1, 1.3; for both, HR = 1.8, 95% CI: 1.4, 2.3). In conclusion, we found associations of a combined GDM/GH indicator with cardiometabolic disease in mothers and with diabetes in fathers, with stronger associations when both GDM and GH were present. © The Author(s) 2017.

Full Text Available Developing countries face the double burden of communicable and non-communicable diseases and of the later hypertension is the most common. It is a major public health challenge with an ever increasing global prevalence which inherently increases the global disease burden whereas awareness of this disease and its determinants are poor. It contributes to about 500000 deaths every year. This was a cross-sectional descriptive community survey carried out in urban and rural communities of Enugu southeast Nigeria. A multi-staged sampling technique was used to recruit 260 participants and data was collected by administering questionnaires. Blood pressure measurement and weight of all the subjects were done. These were analysed using EPI info statistical software version 6.04. The result shows that the prevalence of hypertension in urban and rural areas was 15.4 and 13.8 respectively but was not statistically significantly different. About 17.6 and 23 were perceived hypertensives for urban and rural areas respectively. From the study 17 and 44.5 of urban and rural respondents respectively have suffered from hypertension related illnesses stroke kidney disease heart disease and eye problem. Approximately 45 of urban respondents and 83.7 of rural respondents believed that hypertension can be cured. The source of information and general knowledge of hypertension in urban and rural area was statistically significant pamp88040.05. In the urban area their method of cure include drugs and lifestyle modification while in the rural areas drugs and spiritual means was their way of curing the disease. Prevalence and awareness of hypertension is higher in the urban areas however both communities are grossly unaware of the hypertensive associated diseases. Proper health education is recommended to reduce the prevalence of complications of the disease change the trend and ultimately reduce the death in our environment.

The role of the pharmacist in hypertension management.

Hypertension remains a vital, modifiable risk factor in the prevention of cardiovascular disease. However, many patients do not achieve their therapeutic goals for numerous reasons which can include poor disease insight and nonadherence. Pharmacists can be key players in controlling hypertension, given their medication knowledge and patient counseling skills, yet they remain an underutilized resource in the management of chronic disease states. Various models exist that allow pharmacists to provide direct patient-centered care but practices differ from state to state since pharmacists are not recognized nationally as healthcare providers. This article aims to provide an update on the proven methods in which pharmacists contribute to the management of hypertensive patients. Several recently published studies demonstrate the positive impact of pharmacist intervention and care on patient outcomes in ambulatory and community settings. These practice models include medication therapy management, collaborative drug therapy management, telehealth and team-based care. The role of the pharmacist in hypertension encompasses medication management, disease state education and patient counseling and is most successful when integrated into the patient's care team. Further validation through larger, prospective trials and evaluation of long-term outcomes, such as mortality, remain viable research opportunities.

Full Text Available This article aims to draw attention to the role of psychological factors in morbidity, progression, as well as in the treatment of hypertension. Psychological factors, especially how a person regulates negative emotions, can contribute to the increased risk of cardiovascular disease or exacerbation of these diseases. Over the past several decades, many data have been collected showing the relationship of psycho-emotional factors to the development and development of somatic diseases, including hypertension. More and more research shows that emotional regulation is associated with the occurrence and severity of hypertension. The consequence of this knowledge is the search for psychosocial interventions that could lead to a reduction in blood pressure in hypertensive people. Among them, preliminary research deals with such interventions as meditation training including transcendental meditation, slow breath training, and Mindfulness-Based Stress Reduction (MBSR training. In these training sessions hope is also given in cases where it is difficult to normalize the pressure values with only normotensive drugs.

Hypertension is one of the important contributing factors linked with both causation and development of kidney disease. It is a multifactorial, polygenic, and complex disorder due to interaction of several risk genes with environmental factors. The present study was aimed to explore genetic polymorphism in ACE-1 gene as a risk factor for CKD among hypertensive patients. Three hundred patients were enrolled in the study. Ninety were hypertensive patients with CKD taken as cases, whereas 210 hypertensive patients without CKD were taken as controls. Demographic data including age, sex, Body mass index (BMI), and other risk factors were also recorded. DNA was extracted from blood by salting out method. Genotyping of ACE gene was done by PCR technique. All the statistical analysis was done by using Epi Info and SPSS version 16 software (SPSS Inc., Chicago, IL). Mean age was higher in the control group (p ACE gene (OR = 1.42, 95% CI = 0.72-2.81). Similarly, the risk for CKD among hypertensive patients was also associated with D allele of ACE gene (OR = 1.25, 95% CI = 0.86-1.79). It is concluded that ACE-DD genotype may be a risk factor for the causation and development of chronic kidney failure among hypertensive patients.

Full Text Available Abstract Background: Cerebrovascular and hypertensive diseases are among the main causes of death worldwide. However, there are limited data about the trends of these diseases over the years. Objective: To evaluate the temporal trends in mortality rates and proportional mortality from cerebrovascular and hypertensive diseases according to sex and age in Brazil between 1980 and 2012. Methods: We evaluated the underlying causes of death between 1980 and 2012 in both sexes and by age groups for circulatory diseases (CD, cerebrovascular diseases (CBVD, and hypertensive diseases (HD. We also evaluated death due to all causes (AC, external causes (EC, and ill-defined causes of death (IDCD. Data on deaths and population were obtained from the Department of Information Technology of the Unified Health System (Departamento de Informática do Sistema Único de Saúde, DATASUS/MS. We estimated crude and standardized annual mortality rates per 100,000 inhabitants and percentages of proportional mortality rates. Results: With the exception of EC, the mortality rates per 100,000 inhabitants of all other diseases increased with age. The proportional mortality of CD, CBVD, and HD increased up to the age range of 60-69 years in men and 70-79 years in women, and reached a plateau in both sexes after that. The standardized rates of CD and CBVD declined in both sexes. However, the HD rates showed the opposite trend and increased mildly during the study period. Conclusion: Despite the decline in standardized mortality rates due to CD and CBVD, there was an increase in deaths due to HD, which could be related to factors associated with the completion of the death certificates, decline in IDCD rates, and increase in the prevalence of hypertension.

Full Text Available Demetrius Ellis, Yosuke MiyashitaChildren’s Hospital of Pittsburgh of UPMC, University of Pittsburgh School of Medicine, PA, USAAbstract: The prevalence of hypertension has increased at an accelerated rate in older children and adolescents. This has raised great concern about premature development of cardiovascular disease, which has major long-term health and financial implications. While obesity and sedentary habits largely explain this phenomenon, there are other social and cultural influences that may unmask genetic susceptibility to hypertension in the pediatric population. While it is essential to exclude numerous causes of secondary hypertension in every child, these disorders are not discussed in this review. Rather, the aim of this review is to familiarize pediatricians with casual and ambulatory blood pressure measurement, epidemiology, pathophysiology, and management of several common conditions that play a role in the development of hypertension in children and adolescents. Besides primary hypertension and obesity-related hypertension, emphasis is given to epidemiology, measurement of blood pressure, including ambulatory blood pressure monitoring, hypertension associated with drug use, teenage pregnancy, and video and computer games. Lastly, because pediatricians are increasingly confronted with special issues concerning the management of the hypertensive athlete, this topic is also addressed.Keywords: hypertension, adolescents, obesity, drugs, pregnancy, athletes

Control of hypertension is often a problem in the management of end stage renal disease (ESRD). Multiple modalities of treatment are required to prevent cardiovascular and cerebrovascular mortality and morbidity. These include fluid and salt restriction, multidrug regimes and dialysis. We report a case of young 25 years old patient, admitted with chronic renal failure, complicated by malignant and refractory hypertension, not responding to hemodialysis and antihypertensive agent. During stay in hospital, patient also had intracerebral hemorrhage, fits due to uncontrolled hypertension requiring ventilatory support followed. Renal transplant was considered to be the final therapeutic modality. After gradual recovery, a successful live-related renal transplant was performed. As soon as good graft was established, the blood pressure settled and 4 of the 5 antihypertensives were withdrawn. After 2 weeks, patient was discharged in a stable condition with a total stay of about 2 months. (author)

As with adults, pediatric patients with HTN can present with hypertensive crises include hypertensive urgency and hypertensive emergencies. However, pediatric blood pressure problems have a greater chance of being from secondary causes of HTN, as opposed to primary HTN, than in adults. Thorough evaluation of a child with a hypertensive emergency includes accurate blood pressure readings, complete and focused symptom history, and appropriate past medical, surgical, and family history. Physical exam should include height, weight, four-limb blood pressures, a general overall examination and especially detailed cardiovascular and neurological examinations, including fundoscopic examination. Initial work-up should typically include electrocardiography, chest X-ray, serum chemistries, complete blood count, and urinalysis. Initial management of hypertensive emergencies generally includes the use of intravenous or oral antihypertensive medications, as well as appropriate, typically outpatient, follow-up. Emergency department goals for hypertensive crises are to (1 safely lower blood pressure, and (2 treat/minimize acute end organ damage, while (3 identifying underlying etiology. Intravenous antihypertensive medications are the treatment modality of choice for hypertensive emergencies with the goal of reducing systolic blood pressure by 25% of the original value over an 8

Most patients with hypertension have essential hypertension or well-known forms of secondary hypertension, such as renal disease, renal artery stenosis, or common endocrine diseases (hyperaldosteronism or pheochromocytoma). Physicians are less aware of drug induced hypertension. A variety of therapeutic agents or chemical substances may increase blood pressure. When a patient with well controlled hypertension is presented with acute blood pressure elevation, use of drug or chemical substance which increases blood pressure should be suspected. Drug-induced blood pressure increases are usually minor and short-lived, although rare hypertensive emergencies associated with use of certain drugs have been reported. Careful evaluation of prescription and non-prescription medications is crucial in the evaluation of the hypertensive individual and may obviate the need for expensive and unnecessary evaluations. Discontinuation of the offending agent will usually achieve adequate blood pressure control. When use of a chemical agent which increases blood pressure is mandatory, anti-hypertensive therapy may facilitate continued use of this agent. We summarize the therapeutic agents or chemical substances that elevate blood pressure and their mechanisms of action. Copyright © 2015 Elsevier B.V. All rights reserved.

Neurological disorders in hypertensive patients

Full Text Available Hypertension is one of the most common vascular diseases. The brain as target organs in hypertension is damaged more often and earlier. Neurological complications due to hypertension are frequently hyperdiagnosed in Russian neurological practice. Thus, headache, dizziness, impaired recall of recent events, nocturnal sleep disorders, and many other complaints in a hypertensive patient are usually regarded as a manifestation of dyscirculatory encephalopathy. At the same time headaches (tension headache and migraine in hypertensive patients are predominantly primary; headache associated with dramatic marked elevations in blood pressure is encountered in only a small number of patients. The role of cerebrovascular diseases in the development of dizziness in hypertensive patients is also overestimated. The vast majority of cases, patients with this complaint are in fact identified to have benign paroxysmal postural vertigo, Mеniеre’s disease, vestibular neuronitis, or vestibular migraine. Psychogenic disorders or multisensory insufficiency are generally responsible for non-systemic vertigo in hypertensive patients. Chronic cerebral circulatory insufficiency may cause non-systemic vertigo as a subjective equivalent of postural instability.Cognitive impairments (CIs are the most common and earliest manifestation of cerebrovascular lesion in hypertension. In most cases, CIs in hypertension were vascular and associated with cerebrovascular lesion due to lacunar infarcts and leukoaraiosis. However, mixed CIs frequently occur when hypertensive patients are also found to have signs of a degenerative disease, most commonly in Alzheimer’s disease.

Full Text Available Objectives: To estimate the prevalence of pre-hypertension and its association with some selected cardiovascular risk factors among the Omani adult population in the primary healthcare setting.Method: A cross-sectional study involving a sample taken from a National Screening Program of chronic non-communicable diseases in primary healthcare institutions, Sohar city, Sultanate of Oman (July 2006 - December 2007. Inclusion criteria included Omanis aged 40 years or above residents of Sohar city attending primary healthcare institutions not previously diagnosed with diabetes mellitus, hypertension, or chronic kidney diseases. Descriptive statistics were used to describe the demographic, physical and metabolic characteristics. Univariate analysis was used to identify the significant association between the characteristics and normal blood pressure, pre-hypertension and hypertension. Chi-squared test was used for categorical variables analysis and independent t-test was used for continuous variables analysis. In order to examine the strength of significant associations, the multinomial logistic regression analysis was used.Results: There were 1498 participants, 41% were males and 59% were females. Overall, pre-hypertension was observed in 45% of the total study population (95% CI: 0.422 - 0.473. There were more males affected than females (46% versus 44%. About 34% of the total study population was hypertensive. The multinomial logistic regression analysis revealed that an increase of one unit of age, body mass index, fasting blood glucose and total blood cholesterol, were significantly associated with higher risk in both pre-hypertension and hypertension. High odds ratio of pre-hypertension and hypertension was found with the total blood cholesterol.Conclusion: The prevalence of pre-hypertension was high among the Omani adult population.

Previous research has found a positive short-term relationship between the 2008 collapse and hypertension in Icelandic males. With Iceland's economy experiencing a phase of economic recovery, an opportunity to pursue a longer-term analysis of the collapse has emerged. Using data from a nationally representative sample, fixed-effect estimations and mediation analyses were performed to explore the relationship between the Icelandic economic collapse in 2008 and the longer-term impact on hypertension and cardiovascular health. A sensitivity analysis was carried out with pooled logit models estimated as well as an alternative dependent variable. Our attrition analysis revealed that results for cardiovascular diseases were affected by attrition, but not results from estimations on the relationship between the economic crisis and hypertension. When compared to the boom year 2007, our results point to an increased probability of Icelandic women having hypertension in the year 2012, when the Icelandic economy had recovered substantially from the economic collapse in 2008. This represents a deviation from pre-crisis trends, thus suggesting a true economic-recovery impact on hypertension.

Hypertensive disorders in pregnancy (HDP) have been shown to predict later risk of cardiovascular disease (CVD). However, previous studies have not accounted for subsequent pregnancies and their complications, which are potential confounders and intermediates of this association. A cohort of 146 748 women with a first pregnancy was constructed using the Clinical Practice Research Datalink. HDP was defined using diagnostic codes, elevated blood pressure readings, or new use of an anti-hypertensive drug between 18 weeks' gestation and 6 weeks post-partum. The study outcomes were incident CVD and hypertension. Marginal structural Cox models (MSM) were used to account for time-varying confounders and intermediates. Time-fixed exposure defined at the first pregnancy was used in secondary analyses. A total of 997 women were diagnosed with incident CVD, and 6812 women were diagnosed with hypertension or received a new anti-hypertensive medication during the follow-up period. Compared with women without HDP, those with HDP had a substantially higher rate of CVD (hazard ratio (HR) 2.2, 95% confidence interval (CI) 1.7, 2.7). In women with HDP, the rate of hypertension was five times that of women without a HDP (HR 5.6, 95% CI 5.1, 6.3). With overlapping 95% CIs, the time-fixed analysis and the MSM produced consistent results for both outcomes. Women with HDP are at increased risk of developing subsequent CVD and hypertension. Similar estimates obtained with the MSM and the time-fixed analysis suggests that subsequent pregnancies do not confound a first episode of HDP and later CVD. © 2017 John Wiley & Sons Ltd.

Our study aimed to determine the prevalence of occult left-heart disease in patients with scleroderma and pulmonary hypertension. In patients with pulmonary hypertension (mean pulmonary artery pressure (mean PAP)≥25 mmHg), differentiation between pre- and post-capillary pulmonary hypertension has been made according to pulmonary artery wedge pressure (PAWP) less than or more than 15 mmHg, respectively. We performed a retrospective chart review of 107 scleroderma patients. All patients with suspected pulmonary hypertension had routine right or left heart catheterisation with left ventricular end-diastolic pressure (LVEDP) measurement pre-/post-fluid challenge. We extracted demographic, haemodynamic and echocardiographic data. Patients were classified into one of four groups: haemodynamically normal (mean PAP15 mmHg); occult PVH (mean PAP≥25 mmHg, PAWP≤15 mmHg, LVEDP>15 mmHg before or after fluid challenge); and pulmonary arterial hypertension (PAH) (mean PAP≥25 mmHg, PAWP≤15 mmHg and LVEDP≤15 mmHg before or after fluid challenge). 53 out of 107 patients had pulmonary hypertension. Based on the PAWP-based definition, 29 out of 53 had PAH and 24 out of 53 had PVH. After considering the resting and post-fluid-challenge LVEDP, 11 PAH patients were reclassified as occult PVH. The occult PVH group was haemodynamically, echocardiographically and demographically closer to the PVH group than the PAH group. PVH had high prevalence in our scleroderma-pulmonary hypertension population. Distinguishing PAH from PVH with only PAWP may result in some PVH patients being misclassified as having PAH.

Cardiovascular abnormalities are frequently the cause, as well as the effect, of elevated blood pressure. As such, early cardiovascular disease (CVD) may be established before identifiable blood pressure thresholds are crossed. To identify individuals at risk for CVD at an earlier point in the disease process, as well as to avoid labeling persons as hypertensive who are at low risk for CVD, the Hypertension Writing Group proposes incorporating the presence or absence of cardiovascular risk factors, early disease markers, and target organ damage into the definition and classification scheme of hypertension. To describe both the complexity and progressive nature of hypertension, the following definition is proposed: "Hypertension is a progressive cardiovascular syndrome arising from complex and interrelated etiologies. Early markers of the syndrome are often present before blood pressure elevation is observed; therefore, hypertension cannot be classified solely by discrete blood pressure thresholds. Progression is strongly associated with functional and structural cardiac and vascular abnormalities that damage the heart, kidneys, brain, vasculature, and other organs and lead to premature morbidity and death." Classification of hypertension must involve assessing global cardiovascular risk to situate an individual's risk for CVD and events along a continuum. As knowledge of early CVD continues to evolve, the approach to classifying individuals along that continuum can be expected to evolve accordingly. The four categories currently used to classify hypertension are normal, prehypertension, and stages 1 and 2 hypertension. The population identified with prehypertension includes a subgroup with early CVD. We believe it would be preferable to classify all individuals as either normal or hypertensive, based on their cardiovascular evaluation, using the four categories of normal and stages 1, 2, and 3 hypertension.

Management of hypertension and heart failure in patients with Addison's disease.

2015-06-01

Addison's disease may be complicated by hypertension and less commonly by heart failure. We review the pathophysiology of the renin-angiotensin-aldosterone axis in Addison's disease and how this is altered in the setting of hypertension and heart failure. An essential first step in management in both conditions is optimizing glucocorticoid replacement and considering dose reduction if excessive. Following this, if a patient with Addison's disease remains hypertensive, the fludrocortisone dose should be reviewed and reduced if there are clinical and/or biochemical signs of mineralocorticoid excess. In the absence of such signs, where the renin is towards the upper end of the normal range or elevated, an angiotensin II (AII) receptor antagonist or angiotensin converting enzyme (ACE) inhibitor is the treatment of choice, and the fludrocortisone dose should remain unchanged. Dihydropyridine calcium channel blockers are clinically useful as second line agents, but diuretics should be avoided. In the setting of heart failure, there is an increase in total body sodium and water; therefore, it is appropriate to reduce and rarely consider ceasing the fludrocortisone. Loop diuretics may be used, but not aldosterone antagonists such as spironolactone or eplerenone. Standard treatment with ACE inhibitors, or as an alternative, AII receptor antagonists, are appropriate. Measurements of renin are no longer helpful in heart failure to determine the volume status but plasma levels of brain natriuretic peptide (BNP/proBNP) may help guide therapy. © 2014 John Wiley & Sons Ltd.

Full Text Available Anish Desai, Shilpa A Desouza Division of Pulmonary and Critical Care Medicine, Winthrop-University Hospital, Mineola, NY, USA Abstract: Pulmonary hypertension (PH is defined by a mean pulmonary artery pressure ≥ 25 mmHg, as determined by right heart catheterization. Pulmonary arterial hypertension (PAH can no longer be considered an orphan disease given the increase in awareness and availability of new drugs. PH carries with it a dismal prognosis and leads to significant morbidity and mortality. Symptoms can range from dyspnea, fatigue and chest pain to right ventricular failure and death. PH is divided into five groups by the World Health Organization (WHO, based on etiology. The most common cause of PH in developed countries is left heart disease (group 2, owing to the epidemic of heart failure (HF. The data regarding prevalence, diagnosis and treatment of patients with group 2 PH is unclear as large, prospective, randomized controlled trials and standardized protocols do not exist. Current guidelines do not support the use of PAH-specific therapy in patients with group 2 PH. Prostacyclins, endothelin receptor antagonists, phosphodiesterase-5 inhibitors and guanylate cyclase stimulators have been tried in treatment of patients with HF and/or group 2 PH with mixed results. This review summarizes and critically appraises the evidence for diagnosis and treatment of patients with group 2 PH/HF and suggests directions for future research.

Chronic kidney disease (CKD) has been shown to result in profound changes in the composition and functions of the gut microbial flora which by disrupting intestinal epithelial barrier and generating toxic by-products contributes to systemic inflammation and the associated complications. On the other hand, emerging evidence points to the role of the gut microbiota in the development and progression of CKD by provoking inflammation, proteinuria, hypertension, and diabetes. These observations demonstrate the causal interconnection between the gut microbial dysbiosis and CKD. The gut microbiota closely interacts with the inflammatory, renal, cardiovascular, and endocrine systems via metabolic, humoral, and neural signaling pathways, events which can lead to chronic systemic inflammation, proteinuria, hypertension, diabetes, and kidney disease. Given the established role of the gut microbiota in the development and progression of CKD and its complications, favorable modification of the composition and function of the gut microbiome represents an appealing therapeutic target for prevention and treatment of CKD. This review provides an overview of the role of the gut microbial dysbiosis in the pathogenesis of the common causes of CKD including hypertension, diabetes, and proteinuria as well as progression of CKD.

[Major nutrition-related risk factors of ischemic heart disease: dyslipoproteinemia, obesity, hypertension, glucose intolerance].

Science.gov (United States)

Pados, G

1999-07-11

Of the major risk factors of coronary heart disease dyslipoproteinemia, obesity, hypertension, and diabetes are nutrition related and can be considered of metabolic origin. Dyslipoproteinemia affects 2/3 of the adult population. The risk of coronary heart disease can be decreased 2-5 fold by lowering hypercholesterinemia; atherosclerosis in the coronaries may regress and total mortality may decrease. Atherogenic dyslipidemia (i.e. hypertriglyceridaemia, low HDL cholesterol levels, elevated concentrations of small dense LDL) increases the risk as part of the metabolic syndrome. Obesity is already highly prevalent, and it is affecting ever growing proportions of the adult population. Abdominal obesity furthermore predisposes patients to complications. No effective therapy is available for obesity. 3/4 of hypertensive patients are obese and more than half of them have insulin resistance. By decreasing blood pressure, the risk of stroke decreases by about 40%, that of coronary heart disease by 14-30%. Slimming cures are the most important non-pharmacological way of treating hypertension. 5% of the population has diabetes mellitus, and a further 5% has impaired glucose tolerance. Type 2 diabetes predisposes patients to macrovascular complications. The risk of coronary heart disease can be decreased by controlling diabetes by e.g. metformin.

Hypertension in children and adolescents: epidemiology and pathogenesis.

High blood pressure is one among the leading contributors to burden of disease globally. Approximately 54 % of stroke and 47 % of ischemic heart disease events worldwide were attributable to high blood pressure in the year 2001. There is deficiency of data on the long-term outcome of hypertension in children. In spite of this, there is sufficient evidence to suspect that the health risks of hypertension in pediatric patients are substantial. Hypertension in childhood is known to result in hypertension in young adulthood. The epidemiology of hypertension in children is well represented from various studies conducted across continents. Factors like methodological issues in measurement, socio demographic differences, adiposity levels and ethnicity appear to influence the distribution of blood pressure as well as prevalence of hypertension in children. The etio-pathogenesis of essential (primary) hypertension is multi-factorial in origin. Obesity, insulin resistance, activation of sympathetic nervous system, alterations in sodium homeostasis, renin-angiotensin system changes, changes in vascular smooth muscle structure and reactivity, high serum uric acid levels, genetic factors and fetal programming have been reported to contribute to this disorder. The causes of secondary hypertension vary with age. Renal disorders and coarctation of the aorta are the most common causes of hypertension in children up to age 6 y. In older children, renal parenchymal disease remains the most frequent cause of increased blood pressure. Other causes of hypertension in children are relatively rare and include systemic arteritis and certain tumours, endocrine dysfunction, and neurologic disorders.

Globally essential hypertension and cardiovascular diseases are associated with high morbidity and mortality due to unhealthy life styles and lack of preventative measures. In some ethnicities these factors are insignificant due to genetic makeup favoring protection against these diseases. To study the prevalence of risk factors for essential hypertension in the Pakistani population of a desert area of Thar. A random cross sectional study was done from 2002 to 2008 on 276 subjects (126 males, 150 females) in Islamkot-Thar, the desert area of Sindh. Data for anthropometric, demographic, socioeconomic, dietary pattern, basal metabolic index, body fat content, antihypertensive use and psychosocial factors were recorded. Three consecutive readings for blood pressure were taken in 15 minutes. Any systolic blood pressure of over 140mm Hg and diastolic of over 90mm Hg in all 3 readings was taken as hypertension. Study population was divided in hypertensives (patients) and non hypertensives (controls). Data were analyzed in two steps clinically, descriptively and inferentially using SPSS version 14, first for entire population and second by breaking this population into two sub ethnicities having no consanguinity in them. Hypertension was seen in (10.9%) cases while 88.4 % were normotensive. Hypertensive group showed increased association of risk factors e.g. male gender, old age, marriage, moderately high monthly income, lack of exercise, low leisure time activity, prolonged tobacco exposure, parental history, high basal metabolic index profile, intermediate body fat content and stressful job. However, this group showed lack of association of factors like alcohol, extra salt, scarce education and stress. Decrease association with saturated fat was seen as compared to oil (20.7% versus 79.3%). Subethnicity analysis of the two communities, both having no consanguinity showed one group to be suffering from essential hypertension (17%) and its comorbids like diabetes mellitus

Hypertension accounts for 1 in 5 deaths among American women, posing a greater burden for women than men, and is among their most important risk factors for death and development of cardiovascular and other diseases. Hypertension affects women in all phases of life, with specific characteristics relating to risk factors and management for primary prevention of hypertension in teenage and young adult women; hypertension in pregnancy; hypertension during use of oral contraceptives and assisted reproductive technologies, lactation, menopause, or hormone replacement; hypertension in elderly women; and issues of race and ethnicity. All are detailed in this review, as is information relative to women in clinical trials of hypertension and medication issues. The overarching message is that effective treatment and control of hypertension improves cardiovascular outcomes. But many knowledge gaps persist, including the contribution of hypertensive disorders of pregnancy to cardiovascular disease risk, the role of hormone replacement, blood pressure targets for elderly women, and so on.

Full Text Available Abstract Background Chronic kidney disease is an important public health threat. Such patients present high morbidity and mortality due to cardiovascular disease, with low quality of life and survival, and also high expenditure resulting from the treatment. Arterial hypertension is both a cause and a complication of kidney disease; also, arterial hypertension is a risk factor for cardiovascular disease among patients with kidney diseases. There is some evidence that exercise interventions may be beneficial to chronic kidney disease patients, but previous studies included only end-stage patients, i.e. those undergoing dialysis. This study aims to evaluate the effect of exercise on kidney function, quality of life and other risk factors for cardiovascular disease among non-diabetic chronic hypertensive kidney disease patients who are not undergoing dialysis. Methods The participants will be located through screening hypertensive patients attended within the public healthcare network in Pelotas, a city in south of Brazil. Eligible individuals will be those with glomerular filtration rate between 15 and 59 ml/min x 1.73 m2. The randomization will be done in fixed-size blocks of six individuals such that 75 participants will be allocated to each group. At baseline, information on demographic, socioeconomic, behavioral, anthropometric, blood pressure and quality-of-life variables will be collected, and laboratory tests will be performed. The intervention will consist of three weekly physical exercise sessions lasting 60–75 minutes each, with a total duration of 16 weeks. The outcomes will be the kidney function progression rate, quality of life, blood pressure, lipid profile, hemoglobin level, ultrasensitive C-reactive protein level, and ankle-arm index. The patients in both groups (intervention and control will be reassessed and compared partway through the study (8th week, at the end of the intervention (16th week and in the 8th week after

The liver is vulnerable to as host of disease processes, including portal hypertension. This is a severe hepatic condition in which the liver is subject to numerous imbalances: increased hepatic blood flow, increased portal vein pressure due to extrahepatic portal vein obstruction, and/or increases in hepatic blood flow resistance. Although many diseases states may be responsible for the development of portal hypertension, it is most commonly associated with moderately severe or advanced cirrhosis. Advanced, untreated portal hypertension may cause additional complications such as hepatosplenomegaly, gastrointestinal bleeding, and ascites

Pulmonary vascular complications in portal hypertension and liver disease: A concise review

Directory of Open Access Journals (Sweden)

M. Porres-Aguilar

2013-01-01

Full Text Available Chronic liver disease and/or portal hypertension may be associated with one of the two pulmonary vascular complications: portopulmonary hypertension and hepatopulmonary syndrome. These pulmonary vascular disorders are notoriously underdiagnosed; however, they have a substantial negative impact on survival and require special attention in order to understand their diagnostic approach and to select the best therapeutic options. Portopulmonary hypertension results from excessive vasoconstriction, vascular remodeling, and proliferative and thrombotic events within the pulmonary circulation that lead to progressive right ventricular failure and ultimately to death. On the other hand, abnormal intrapulmonary vascular dilations, profound hypoxemia, and a wide alveolar-arterial gradient are the hallmarks of the hepatopulmonary syndrome, resulting in difficult-to-treat hypoxemia. The aim of this review is to summarize the latest pathophysiologic concepts, diagnostic approach, therapy, and prognosis of portopulmonary hypertension and hepatopulmonary syndrome, as well as to discuss the role of liver transplantation as a definitive therapy in selected patients with these conditions.

To determine whether women with a history of juvenile arthritis are at higher risk for heart disease and hypertension and for developing adverse maternal outcomes: gestational diabetes mellitus, maternal hypertension, and preeclampsia/eclampsia. We designed a nested case-control study from a cohort of first-time mothers with prior physician billing codes suggesting juvenile arthritis, and a matched comparison group without juvenile arthritis. For the nested case-control design, we selected 3 controls for each case for the outcomes of heart disease (n = 403), prepregnancy hypertension (n = 66), gestational diabetes mellitus (n = 285), maternal hypertension (n = 561), and preeclampsia/eclampsia (n = 236). We used conditional logistic regression, adjusting for maternal age and education. Having juvenile arthritis was associated with heart disease (odds ratio [OR] 2.44 [95% confidence interval (95% CI) 1.15-5.15]) but not with gestational hypertension, diabetes mellitus, or preeclampsia/eclampsia. All 66 cases of prepregnancy hypertension had juvenile arthritis. Having prepregnancy hypertension was strongly associated with preeclampsia/eclampsia (OR 8.05 [95% CI 2.69-24.07]). Women with a history of juvenile arthritis had a higher risk of heart disease. This risk signals the potential importance of cardiac prevention strategies in juvenile arthritis. As this was a retrospective study, it was not possible to correct for some relevant potential confounders. Further studies should assess the impact of medications, disease severity, and other factors (e.g., obesity) on cardiac outcomes in juvenile arthritis. © 2016, American College of Rheumatology.

Pulmonary hypertension in the perinatal period can present acutely (persistent pulmonary hypertension of the newborn) or chronically. Clinical and echocardiographic diagnosis of acute pulmonary hypertension is well accepted but there are no broadly validated criteria for echocardiographic diagnosis of pulmonary hypertension later in the clinical course, although there are significant populations of infants with lung disease at risk for this diagnosis. Contributing cardiovascular comorbidities are common in infants with pulmonary hypertension and lung disease. It is not clear who should be treated without confirmation of pulmonary vascular disease by cardiac catheterization, with concurrent evaluation of any contributing cardiovascular comorbidities.

Reductions in hydrogen sulfide (H 2 S) production have been implicated in the pathogenesis of hypertension; however, no studies have examined the functional role of hydrogen sulfide in hypertensive heart disease. We hypothesized that the endogenous production of hydrogen sulfide would be reduced and exogenous hydrogen sulfide would ameliorate cardiac dysfunction in N ω -nitro- L-arginine methyl ester ( L-NAME)-induced hypertensive rats. Therefore, this study investigated the cardioprotective effects of hydrogen sulfide on L-NAME-induced hypertensive heart disease and explored potential mechanisms. The rats were randomly divided into five groups: Control, Control + sodium hydrosulfide (NaHS), L-NAME, L-NAME + NaHS, and L-NAME + NaHS + glibenclamide (Gli) groups. Systolic blood pressure was monitored each week. In Langendorff-isolated rat heart, cardiac function represented by ±LV dP/dt max and left ventricular developing pressure was recorded after five weeks of treatment. Hematoxylin and Eosin and Masson's trichrome staining and myocardium ultrastructure under transmission electron microscopy were used to evaluate cardiac remodeling. The plasma nitric oxide and hydrogen sulfide concentrations, as well as nitric oxide synthases and cystathionine-γ-lyase activity in left ventricle tissue were determined. The protein expression of p-Akt, Akt, p-eNOS, and eNOS in left ventricle tissue was analyzed using Western blot. After five weeks of L-NAME treatment, there was a time-dependent hypertension, cardiac remodeling, and dysfunction accompanied by a decrease in eNOS phosphorylation, nitric oxide synthase activity, and nitric oxide concentration. Meanwhile, cystathionine-γ-lyase activity and hydrogen sulfide concentration were also decreased. NaHS treatment significantly increased plasma hydrogen sulfide concentration and subsequently promoted the Akt/eNOS/NO pathway which inhibited the development of hypertension and attenuated cardiac remodeling and

To estimate pulmonary hypertension, we measured postural differences in pulmonary blood flow for the lateral decubitus positions on perfusion lung scintigrams with Tc-99 m macro-aggregated albumin, applying the method devised by Tanaka et al (Eur J Nucl Med 17: 320-326, 1990). Utilizing a scintillation camera coupled to a minicomputer system, changes in the distribution of pulmonary blood flow caused by gravitational effects, namely, changes in the total count ratios for the right lung versus the left lung in the right and left lateral decubitus positions (R/L), were obtained for 44 patients with lung disease, 95 patients with valvular heart disease, and 23 normal subjects. Mean standard deviation in the R/L ratios was 3.09{+-}1.28 for the normal subjects, 1.97{+-}0.89 for the patients with lung disease, and 1.59{+-}0.59 for the patients with valvular heart disease. The R/L ratios correlated with mean pulmonary arterial pressure and cardio-thoracic ratios in the lung disease and valvular heart disease groups, with pulmonary arteriolar resistance in the former, and with pulmonary capillary wedge pressure in the latter. Defining pulmonary hypertension (>20 mmHg) as an R/L ratio of less than 1.81, which is the mean-1 standard deviation for normal subjects, the sensitivity and the specificity of the R/L ratio for the diagnosis of pulmonary hypertension were 62.9% and 76.2%, respectively, for the lung disease patients, and 80.3% and 61.8%, respectively, for the valvular heart disease patients. This method seems to be useful for the pathophysiologic evaluation of pulmonary perfusion in cases of lung disease and valvular heart disease. (author)

Objective: To evaluate pulmonary hypertension (PH) using first-pass radionuclide angiography in patients with valvular heart disease. Methods: One hundred and forty patients (54 males, 86 females, average age of 44.75±10.84) with valvular disease were included in this study. Swan-Ganz thermodilution catheterization, echocardiography and first-pass radionuclide angiography were performed on all patients before surgery. Patients were divided into four groups: pulmonary artery pressure (PAP) normal group [mean PAP (MPAP)<20 mm Hg(1mm Hg=0.133 kPa)]; PAP slightly risen group (20 mm Hg≤MPAP<30 mm Hg); PAP moderately risen group (30 mm Hg≤MPAP<50 mm Hg); PAP highly risen group (MPAP≥50 mm Hg). Thirteen subjects with coronary heart disease and 40 normal subjects (36 males, 17 females, average age of 46.30±11.19) were included as control group. First-pass radionuclide angiography was performed on these subjects, Swan-Ganz thermodilution catheterization was performed on patients with coronary heart disease. Results: 1) Lung equilibrium time (LET) values by first-pass radionuclide angiography were (16.88±5.12), (15.89±4.69), (18.56±3.04), (25.37±5.89), (37.69±6.25) and (61.33±10.14) s in coronary heart disease group, normal subject group and four valvular heart disease groups, respectively. The differences were significant among four valvular heart disease groups; and among control group, PAP slightly risen group, PAP moderately risen group, PAP highly risen group (P<0.001). 2) Correlation coefficient between LET and MPAP from the afloat catheter manometer was 0.88 and between systolic PAP (SPAP) from echocardiography and SPAP from the afloat catheter manometer was 0.64. 3) Agreement was 71%, 78%, 81%, 100% between LET and MPAP in four valvular heart disease groups, respectively. 4) Sensitivity, specificity and accuracy of PAP using LET measuring was 85%, 79% and 83%, respectively. Conclusion: First-pass radionuclide angiography is an accurate and noninvasive

Hypertension in pregnancy is a risk factor for future hypertension and cardiovascular disease. This may reflect an underlying familial predisposition or persistent damage caused by the hypertensive pregnancy. We sought to isolate the effect of hypertension in pregnancy by comparing the risk of hypertension and cardiovascular disease in women who had hypertension in pregnancy and their sisters who did not using the dataset from the Genetic Epidemiology Network of Arteriopathy study, which examined the genetics of hypertension in white, black, and Hispanic siblings. This analysis included all sibships with at least one parous woman and at least one other sibling. After gathering demographic and pregnancy data, BP and serum analytes were measured. Disease-free survival was examined using Kaplan–Meier curves and Cox proportional hazards regression. Compared with their sisters who did not have hypertension in pregnancy, women who had hypertension in pregnancy were more likely to develop new onset hypertension later in life, after adjusting for body mass index and diabetes (hazard ratio 1.75, 95% confidence interval 1.27–2.42). A sibling history of hypertension in pregnancy was also associated with an increased risk of hypertension in brothers and unaffected sisters, whereas an increased risk of cardiovascular events was observed in brothers only. These results suggest familial factors contribute to the increased risk of future hypertension in women who had hypertension in pregnancy. Further studies are needed to clarify the potential role of nonfamilial factors. Furthermore, a sibling history of hypertension in pregnancy may be a novel familial risk factor for future hypertension. PMID:26315531

Ischemic Heart Diseases (IHD) have the highest cause of mortality in the Islamic Republic of Iran. Unhealthy dietary habits as a major threat make our country prone to an epidemic of non-communicable diseases in the next two decades. The aim of this study was to determine the association of diet, hypertension, hypercholesterolemia and diabetes with risk of developing IHD in Tehran. This case - control study was conducted during 2003 and 2004 in Tehran Heart Center and Tehran Shahid Rajaii Hospital. A sample of 100 IHD patients (cases) and 100 individuals free of cardiovascular symptoms (controls) were entered into the study; the Controls were matched to the IHD patients by age (+- years) and sex. Information was recorded by Food Frequency Questionnaire (FFQ). All data were analyzed with the SPSS for windows, version11. Multivariate analysis showed a significant and positive association between Hypertension, Hypercholesterolemia and Diabetes and risk of developing IHD. Odds ratios for these three risk factors with 95% confidence interval (CI) were: 3.9, 12 and 8.6 respectively. In he cases consumption of high dairy fat and fried foods were significantly high, that increased the risk of IHD 9.8 and 54.6 times, respectively. Also low intake of fish was directly associated with increase of the IHD risk (95% CI, OR: 13.9). Moreover low consumption of vegetables and fruits independently increased the risk of IHD 19.8 times in cases group. Hypertension, hypercholesterolemia and diabetes have a significant association with development of IHD. High consumption of fatty food and low consumption of fish, vegetables and fruits also contribute to development of IHD. (author)

Full Text Available BACKGROUND: Hypertension is a worldwide epidemic disease. It is more common and more severe in elderly persons. Various studies however have estimated 41.9 million men and 27.8 million women to have prehypertension. Diagnosis and early treatment of prehypertension are of utmost importance. Although hypertension is usually divided into 2 general categories of essential (primary and secondary hypertension, the initial treatment for hypertension often depends on its stage which is determined by systolic and diastolic blood pressure. Lifestyle modification is the first step in treating stage one hypertension. Pharmaceutical treatments including diuretics, angiotensin converting enzyme (ACE inhibitors, calcium blockers, beta blockers, and angiotensin receptor blockers will be recommended if lifestyle modification fails to control blood pressure.    METHODS: The PubMed database was searched by a number of keywords including hypertension, pharmaceutical treatment, and non-pharmaceutical treatment. The results were limited by determining a date range of 2008-11.    RESULTS: High blood pressure causes major health problems for many people around the world. It should be controlled because of its high mortality and morbidity. However, in order to select an appropriate treatment modality, it is initially important to diagnose the kinds and stages of hypertension. Pharmaceutical or non-pharmaceutical treatments can then be employed to control this serious disease.    CONCLUSION: Treating hypertension depends on the kinds and stages of this disease. Several tips should be considered when selecting a method of treatment.       Keywords: Hypertension, Pharmacological treatment, Non-pharmacological treatment

Physio-pathological effects of alcohol on the cardiovascular system: its role in hypertension and cardiovascular disease.

Science.gov (United States)

Kawano, Yuhei

2010-03-01

Alcohol has complex effects on the cardiovascular system. The purpose of this article is to review physio-pathological effects of alcohol on cardiovascular and related systems and to describe its role in hypertension and cardiovascular disease. The relationship between alcohol and hypertension is well known, and a reduction in the alcohol intake is widely recommended in the management of hypertension. Moreover, alcohol has both pressor and depressor actions. The latter actions are clear in Oriental subjects, especially in those who show alcohol flush because of the genetic variation in aldehyde dehydrogenase activity. Repeated alcohol intake in the evening causes an elevation in daytime and a reduction in nighttime blood pressure (BP), with little change in the average 24-h BP in Japanese men. Thus, the hypertensive effect of alcohol seems to be overestimated by the measurement of casual BP during the day. Heavy alcohol intake seems to increase the risk of several cardiovascular diseases, such as hemorrhagic stroke, arrhythmia and heart failure. On the other hand, alcohol may act to prevent atherosclerosis and to decrease the risk of ischemic heart disease, mainly by increasing HDL cholesterol and inhibiting thrombus formation. A J- or U-shaped relationship has been observed between the level of alcohol intake and risk of cardiovascular mortality and total mortality. It is reasonable to reduce the alcohol intake to less than 30 ml per day for men and 15 ml per day for women in the management of hypertension. As a small amount of alcohol seems to be beneficial, abstinence from alcohol is not recommended to prevent cardiovascular disease.

2013-01-01

Background Hypertension is strongly associated with adverse cardiovascular outcomes and was the leading modifiable associated factor for global disease burden in 2010. Analysis of modifiable associated factors will be important to those concerned with mitigating the adverse effects of hypertension. We studied factors associated with hypertension in adults aged 25–64 years of age in Cambodia in order to help develop strategies for planned new initiatives for prevention and control of hypertension. Methods Using data from a nationwide survey in Cambodia assessing the prevalence of associated factors for non-communicable disease in 2010 (WHO STEPs survey), 5017 participants between the ages of 25 and 64 years were included in a secondary analysis of the prevalence and predictors of hypertension. Results The prevalence of prehypertension in this sample was approximately double that of overall hypertension (27.9% vs 15.3%). Male sex, increasing age and known cardiovascular associated factors, including higher Body Mass Index (BMI), dyslipidaemia, impaired fasting glycaemia, and abdominal obesity were all associated with an increased prevalence of hypertension. In multivariate models, increasing age was the strongest associated factor for hypertension (OR 8.79, 95% CI (5.43 to 14.2)), whereas, higher BMI was the primary associated factor associated with prehypertension (OR 3.27, 95% CI 2.21 to 4.82). Conclusions Modifiable cardiovascular-associated factors are strongly correlated with prehypertension and hypertension in Cambodia, and may be a focus of public health and primary care strategies to mitigate subsequent ischaemic heart disease and stroke. A national strategy aimed at increased screening and adherence to medical therapy is a necessary first step to reduce burden of disease and related morbidities. PMID:27326148

Full Text Available Nilay Kumar,1 David A Calhoun,2 Tanja Dudenbostel21Department of Medicine, 2Division of Cardiovascular Disease, Hypertension and Vascular Biology Program, University of Alabama at Birmingham, Birmingham, AL, USAAbstract: Resistant hypertension (RHTN is an increasingly common clinical problem that is often heterogeneous in etiology, risk factors, and comorbidities. It is defined as uncontrolled blood pressure on optimal doses of three antihypertensive agents, ideally one being a diuretic. The definition also includes controlled hypertension with use of four or more antihypertensive agents. Recent observational studies have advanced the characterization of patients with RHTN. Patients with RHTN have higher rates of cardiovascular events and mortality compared with patients with more easily controlled hypertension. Secondary causes of hypertension, including obstructive sleep apnea, primary aldosteronism, renovascular disease, are common in patients with RHTN and often coexist in the same patient. In addition, RHTN is often complicated by metabolic abnormalities. Patients with RHTN require a thorough evaluation to confirm the diagnosis and optimize treatment, which typically includes a combination of lifestyle adjustments, and pharmacologic and interventional treatment. Combination therapy including a diuretic, a long-acting calcium channel blocker, an angiotensin-converting enzyme inhibitor, a beta blocker, and a mineralocorticoid receptor antagonist where warranted is the classic regimen for patients with treatment-resistant hypertension. Mineralocorticoid receptor antagonists like spironolactone or eplerenone have been shown to be efficacious in patients with RHTN, heart failure, chronic kidney disease, and primary aldosteronism. Novel interventional therapies, including baroreflex activation and renal denervation, have shown that both of these methods may be used to lower blood pressure safely, thereby providing exciting and promising new

The variety of clinical information provided by the echocardiogram (i.e. assessment of left ventricular (LV) structure and geometry, systolic/diastolic function, left atrial and aortic size) in addition to its superior sensitivity for LV hypertrophy detection compared to electrocardiogram are strong arguments supporting the paramount importance of this technique in the assessment of hypertensive heart disease. A number of limitations of the echocardiographic technique, however, including lack of standardized/quantitative procedures, impair its diagnostic accuracy and cost-effectiveness. The aim of these recommendations is to provide a document on the minimum acceptable requirements for the clinical practice of echocardiography in the hypertensive setting and thus to improve the quality of this fundamental tool in the cardiovascular risk stratification of hypertensive patients.

Hypertension constitutes a major health problem and the challenge is to identify patients having 'surgically' curable renal vascular disease among the majority with so-called essential hypertension. The best of unsatisfactory diagnostic tests are renography and plasma renin activity both before and during angiotensin II blockade. The necessity of better screening tests has increased because of the recent advances in surgical techniques and especially percutaneous transluminal renal angioplasty. The latter has definitely become the method of choice for correction of suspected hemodynamically significant artery stenoses whenever technically feasible. With improved angioplasty techniques the risk of treating renal artery stenosis without hemodynamic and clinical importance (so-called cosmetic repair) has increased. Unfortunately randomized trials including surgery versus angioplasty are not available. It should be kept in mind that only after correction of the stenosis is achieved and the blood pressure has become normal, can the diagnosis of renovascular hypertension be made with certainty.

Osteoprotegerin (OPG) is a glycoprotein that plays an important regulatory role in the skeletal, vascular, and immune system. It has been shown that OPG predicts chronic kidney disease (CKD) in diabetic patients. We hypothesized that OPG could be a risk marker of CKD development also in non-diabetic hypertensive patients. A case-control study was carried out to measure circulating OPG levels in 42 hypertensive patients with CKD and in 141 hypertensive patients without CKD. A potential relationship between OPG and the presence of CKD was investigated and a receiver-operating characteristic (ROC) curve was designed thereafter to identify a cut-off value of OPG that best explained the presence of CKD. Secondly, to evaluate whether OPG increase could affect the kidney, 18 C57BL/6J mice were randomized to be treated with saline or recombinant OPG every 3 weeks for 12 weeks. Circulating OPG levels were significantly higher in hypertensive patients with CKD, and there was a significant inverse association between OPG and renal function, that was independent from other variables. ROC analysis showed that OPG levels had a high statistically predictive value on CKD in hypertensive patients, which was greater than that of hypertension. The OPG best cut-off value associated with CKD was 1109.19 ng/L. In the experimental study, OPG delivery significantly increased the gene expression of pro-inflammatory and pro-fibrotic mediators, as well as the glomerular nitrosylation of proteins. This study shows that OPG is associated with CKD in hypertensive patients, where it might have a higher predictive value than that of hypertension for CKD development. Secondly, we found that OPG delivery significantly increased the expression of molecular pathways involved in kidney damage. Further longitudinal studies are needed not only to evaluate whether OPG predicts CKD development but also to clarify whether OPG should be considered a risk factor for CKD.

Full Text Available Pulmonary arterial hypertension (PAH is a rare and highly fatal disease that has been reported in 8 patients with glycogen storage disease type I (GSDI. We describe an additional case of an acute presentation of PAH in a 14-year-old patient with GSDI, which was successfully treated with inhaled nitric oxide and sildenafil. We investigated the incidence of PAH in 28 patients with GSDI on routine echocardiography and found no evidence of PAH and no significant cardiac abnormalities. This study highlights that PAH is a rare disease overall, but our case report and those previously described suggest an increased incidence in patients with GSDI. Should cardiopulmonary symptoms develop, clinicians caring for patients with GSDI should have a high degree of suspicion for acute PAH and recognize that prompt intervention can lead to survival in this otherwise highly fatal disease.

Exercise radionuclide ventriculography (ERV) is considered a superior non-invasive screening test for coronary artery disease (CAD). ERV showed, however, a low specificity in hypertensive patients (H). The diagnostic accuracy of EAR and thallium-201 myocardial scintigraphy (M) was evaluated in 23 patients (H) with chest pain and positive ECG-strees test. All patients underwent ERV and M, randomly, in different days. Finally, they all underwent coronary angiography: CAD was diagnosed in case of luminal narrowing ≥ 70% in 1 major coronary artery at least. Eleven patients had severe CAD. ERV was considered positive for CAD in presence of ex-induced abnormality of wall motion and/or in case of ex-induced ejection fraction increase ≤ 5% respect to the basal values. M was considered positive for CAD when perfusion defects were observed in early images only. ERV showed low diagnostic accuracy. On the contrary M had both sensibility and specificity, and a high positive and negative predictive value in the diagnosis of CAD. M is thus suggested as the non-invasive methodology of choice in hypertensive patients with suspected CAD

Full Text Available Hypertension is a common disease associated with important cardiovascular complications. Persistent blood pressure of 140/90 or higher despite combined use of a reninangiotensin system blocker, calcium channel blocker and a diuretic at highest tolerated doses constitutes resistant hypertension. Excess sympathetic activity plays an important pathogenic role in resistant hypertension in addition to contributing to the development of metabolic problems, in particular diabetes. Reduction of renal sympathetic activity by percutaneous catheter-based radiofrequency ablation via the renal arteries has been shown in several studies to decrease blood pressure in patients with resistant hypertension, and importantly is largely free of significant complications. However, longer term follow-up is required to confirm both long-term safety and efficacy.

This review will provide new information related to pathophysiology and management of specific diseases that have been addressed by selected articles published in the Italian Journal of Pediatrics in 2013, focusing on allergology, endocrinology, gastroenterology, hypertension, infectious diseases, neonatology, neurology, nutrition and respiratory tract illnesses in children. Recommendations for interpretation of skin prick test to foods in atopic eczema, management of allergic conjunctivitis, hypertension and breastfeeding in women treated with antiepileptic drugs and healthy breakfast have been reported. Epidemiological studies have given emphasis to high incidence of autoimmune disorders in patients with Turner syndrome, increasing prevalence of celiac disease, frequency of hypertension in adolescents, incidence and risk factor for retinopathy of prematurity. Advances in prevention include elucidation of the role of probiotics in reducing occurrence of allergies and feeding intolerance, and events of foetal life that influence later onset of diseases. Mechanistic studies suggested a role for vitamin D deficiency in asthma and type 1 diabetes and for reactivation of Varicella-Zoster virus in aseptic meningitis. Regarding diagnosis, a new mean for the diagnosis of hyperbilirubinaemia in newborns, a score for recognition of impaired nutritional status and growth and criteria for early Dyke-Davidoff-Masson Syndrome have been suggested. New therapeutic approaches consist of use of etanercept for reducing insulin dose in type 1 diabetes, probiotics in atopic eczema, and melatonin in viral infections.

The synthetic drug fenoldopam mesylate (FM) may have a renoprotective role, and a "renal dose" of 0.1 µg/kg/min intravenous (IV) infusion of FM has been reported as able to increase renal blood flow without affecting systemic blood pressure. But conclusive data are still lacking. We aimed to investigate by color-Doppler ultrasonography the effects of IV administration of FM at this dosage in hypertensive chronic kidney disease (CKD) patients, and verify whether it may induce any systemic hemodynamic alteration. In 60 hypertensive CKD patients, we measured by duplex Doppler ultrasonography, at baseline and during infusion of 0.1 µg/kg/min of FM, the systolic and diastolic flow velocity (sampled at the renal hilum, intermediate section and origin of both renal arteries) and the intra-parenchymal renal resistive index (RRI) sampled on interlobular arteries of both kidneys. Patients were divided into four subgroups (I-IV) according to classification of National Kidney Foundation Kidney Disease Outcomes Quality Initiative (NKF-DOQI). Infusion of 0.1 µg/kg/min FM significantly decreased the RRI (0.73 ± 0.05 vs. 0.65 ± 0.06; p flow velocities in all renal artery tracts examined. No single episode of systemic hypotension was observed. Very low-dose FM may significantly increase renal blood flow and exert a renal protective effect in hypertensive CKD patients. Infusion of FM at such low dosage appears also to be quite safe, even in CKD and hypertensive patients.

Pulmonary arterial hypertension

2013-01-01

Pulmonary arterial hypertension (PAH) is a chronic and progressive disease leading to right heart failure and ultimately death if untreated. The first classification of PH was proposed in 1973. In 2008, the fourth World Symposium on PH held in Dana Point (California, USA) revised previous classifications. Currently, PH is devided into five subgroups. Group 1 includes patients suffering from idiopathic or familial PAH with or without germline mutations. Patients with a diagnosis of PAH should systematically been screened regarding to underlying mutations of BMPR2 gene (bone morphogenetic protein receptor type 2) or more rarely of ACVRL1 (activine receptor-like kinase type 1), ENG (endogline) or Smad8 genes. Pulmonary veno occusive disease and pulmonary capillary hemagiomatosis are individualized and designated as clinical group 1'. Group 2 'Pulmonary hypertension due to left heart diseases' is divided into three sub-groups: systolic dysfonction, diastolic dysfonction and valvular dysfonction. Group 3 'Pulmonary hypertension due to respiratory diseases' includes a heterogenous subgroup of respiratory diseases like PH due to pulmonary fibrosis, COPD, lung emphysema or interstitial lung disease for exemple. Group 4 includes chronic thromboembolic pulmonary hypertension without any distinction of proximal or distal forms. Group 5 regroup PH patients with unclear multifactorial mechanisms. Invasive hemodynamic assessment with right heart catheterization is requested to confirm the definite diagnosis of PH showing a resting mean pulmonary artery pressure (mPAP) of ≥ 25 mmHg and a normal pulmonary capillary wedge pressure (PCWP) of ≤ 15 mmHg. The assessment of PCWP may allow the distinction between pre-capillary and post-capillary PH (PCWP > 15 mmHg). Echocardiography is an important tool in the management of patients with underlying suspicion of PH. The European Society of Cardiology and the European Respiratory Society (ESC-ERS) guidelines specify its role

The economic aspects of hypertension are critical to modern medicine. The medical, economic, and human costs of untreated and inadequately controlled hypertension are enormous. Hypertension is distributed unequally and with iniquity in different countries and regions of the world. Treatment of hypertension requires an investment over many years to prolong disease-free quality years of life. The high prevalence and high cost of the disease impacts on the microeconomics and macroeconomics of countries and regions. The criteria used for inclusion in clinical guidelines for hypertension impact on the cost and cost/utility of diagnosis or treatment.

Pulmonary hypertension (PH) is a cardio-pulmonary disorder that may involve multiple clinical conditions and can complicate the majority of cardiovascular and respiratory diseases. Its definition is an increase in mean pulmonary artery pressure (mPAP) \\hbox{$\\geqslant $} ⩾ 25 mmHg at rest, leading to right heart failure and ultimately death. The clinical classification of pulmonary hypertension (PH) categorizes PH into groups which share similar pathophysiological and hemodynamic characteristics and treatments. Five groups of disorders that cause PH are identified: pulmonary arterial hypertension (Group 1) which is a pre-capillary PH, defined by a normal pulmonary artery wedge pressure (PAWP) \\hbox{$\\leqslant $} ⩽ 15 mmH, due to remodelling of the small pulmonary arteries (15 mmHg; pulmonary hypertension due to chronic lung disease and/or hypoxia (Group 3); chronic thrombo-embolic pulmonary hypertension (Group 4); and pulmonary hypertension due to unclear and/or multifactorial mechanisms (Group 5). PAH (PH group 1) can be treated with agents targeting three dysfunctional endothelial pathways of PAH: nitric oxide (NO) pathway, endothelin-1 pathway and prostacyclin pathway. Patients at low or intermediate risk can be treated with either initial monotherapy or initial oral combination therapy. In patients at high risk initial combination therapy including intravenous prostacyclin analogues should be considered. Patients with inadequate clinical response to maximum treatment (triple therapy with an intravenous prostacyclin) should be assessed for lung transplantation. Despite progresses, PAH remains a fatal disease with a 3-year survival rate of 58%. Treatment of group 2, group 3 and group 5 PH is the treatment of the causal disease and PAH therapeutics are not recommended. Treatment of group 4 PH is pulmonary endarteriectomy if patients are eligible, otherwise balloon pulmonary angioplasty and/or medical therapy can be considered. © Société de Biologie

BAG3 is a member of human BAG (Bcl-2-associated athanogene) proteins and plays a role in apoptosis, cell adhesion, cytoskeleton remodeling, and autophagy. The aim of this study was to evaluate BAG3 levels in healthy subjects, hypertensive patients, and hypertensive diabetic patients. We enrolled 209 Caucasian adults, of both sex, 18-75 years of age, 77 were healthy controls, 62 were affected by hypertension, and 70 were affected by hypertension and type 2 diabetes. All patients underwent an assessment that included medical history, physical examination, vital signs, a 12-lead electrocardiogram, measurements of systolic (SBP), and diastolic blood pressure (DBP), heart rate (HR), fasting plasma glucose (FPG), glycated hemoglobin (HbA 1c ), triglycerides (TG), transaminases, high sensitivity C-reactive protein (Hs-CRP), and BAG3. We observed higher blood pressure values in hypertensive, and hypertensive diabetic patients compared to controls. As expected, FPG and HbA 1c were higher in diabetic hypertensive patients, compared to the other two groups. No Tg levels differences were recorded among the three groups. Hs-CRP was higher in diabetic hypertensive patients compared to healthy subjects. Finally, BAG3 levels were higher in hypertensives, and hypertensive diabetic patients compared to controls. We observed higher levels of BAG3 in hypertensive patients compared to healthy controls, and even higher levels in hypertensive diabetic patients compared to healthy subjects. This paper could be the first of a long way to identify potential involvement of deregulated BAG3 levels in cardiometabolic diseases. © 2017 Wiley Periodicals, Inc.

Arterial hypertension is a common worldwide disease with a prevalence of approximately 26%. Secondary cause is known in 5-10% of patients with hypertension. We should think of secondary hypertension in all patients with resistant hypertension, in patients with sudden deterioration in the control of hypertension and in patients with laboratory and clinical signs of diseases associated with secondary hypertension. It is important to distinguish between secondary hypertension and pseudo-resistance (noncompliance to treatment, white coat syndrome). Secondary causes of hypertension can be divided into endocrine (primary aldosteronism, pheochromocytoma, hypercortisolism, hyperparathyreoidism), renal - renovascular and renal parenchymal hypertension, and other causes as sleep apnoe syndrome, hypertension in pregnancy, coarctation of the aorta and intracranial tumors.

The mineralocorticoid aldosterone is a key hormone in the regulation of plasma volume and blood pressure in man. Excessive levels of this mineralocorticoid have been shown to mediate metabolic disorders and end-organ damage more than what can be attributed to its effects on blood pressure alone. Inappropriate excess levels of aldosterone contribute significantly to the cardiorenal metabolic syndrome and target organ injury that include atherosclerosis, myocardial hypertrophy, fibrosis, heart failure, and kidney disease. The importance of understanding the role of excess mineralocorticoid hormones such as aldosterone in resistant hypertension and in those with secondary hypertension should be visited. Primary aldosteronism is one of the commonly identified causes of hypertension and is treatable and/or potentially curable. We intend to review the management of mineralocorticoid-induced hypertension in the adult population along with other disease entities that mimic primary aldosteronism.

Such analysis is important to elucidate the effectiveness of this care. To document the current clinical practice for the treatment of hypertension with identification of the profile of requested tests, type of administered treatment, level of blood pressure (BP) control, and adherence to treatment. National, observational, prospective, and multicenter study that will include patients older than 18 years with hypertension for at least 4 weeks, following up in public and private centers and after signing a consent form. The study will exclude patients undergoing dialysis, hospitalized in the previous 30 days, with class III or IV heart failure, pregnant or nursing, with severe liver disease, stroke or acute myocardial infarction in the past 30 days, or with diseases with a survival prognosis crisis, cardiocirculatory events, and cardiovascular death, while secondary outcomes will be hospitalization for heart failure and requirement of dialysis. A subgroup analysis of 15% of the sample will include noninvasive central pressure evaluation at baseline and study end. The estimated sample size is 3,000 individuals for a prevalence of 5%, sample error of 2%, and 95% confidence interval. The results will be presented after the final evaluation, which will occur at the end of a 1-year follow-up. The analysis of this registry will improve the knowledge and optimize the treatment of hypertension in Brazil, as a way of modifying the prognosis of cardiovascular disease in the country.

Managing hypertension: relevant biomarkers and combating bioactive compounds

Full Text Available Hypertension is one of the most common chronic diseases which affects many people who belong to a higher age range. The standard definition that is offered to the general public has a minimum age of 18 years to be diagnosed with hypertension. Many studies have been conducted in the hopes of finding consistent data that provides information on the biomarkers of hypertension and effective forms of treatment. However, there is a tendency for skewed data due to the ineffectiveness of diagnosing hypertension, due to variability in technique or even negligence. Interestingly, research has indicated that there are connections to certain biomarkers of hypertension. However,the results have been deemed inconclusive. Moreover, the results provide promising data for future studies that have an emphasis on biomarkers. The biomarkers that have been consistently brought to researchers’ attention include the following: circulating C-reactive protein (CRP, plasminogen activator inhibitor-1 (PAI-1, urinary albumin:creatinine ratio (UACR, and aldosterone:renin ratio (ARR. These four biomarkers have become the foundation of multiple hypertension studies, even though the only formal conclusion drawn from these studies is that there is a wide range of variables that have some kind of influence on hypertension. More recently, treatment options for hypertension have increasingly become an emphasis for studies, with research predicting that nutrition plays a key role in the managing of diseases. Furthermore, the role of bioactive compounds has gained traction in hypertension research, being loosely correlated to managing specific biomarkers. Ultimately, these correlations to bioactive compounds like antioxidants would demonstrate that certain functional foods have the capacity to help treat hypertension. The modality is to find an alternative option for managing or treating hypertension through natural sources of food or food products fortified with ingredients to

We previously found large variations in general practitioner (GP) hypertension treatment probability in oldest-old (>80 years) between countries. We wanted to explore whether differences in country-specific cardiovascular disease (CVD) burden and life expectancy could explain the differences. This is a survey study using case-vignettes of oldest-old patients with different comorbidities and blood pressure levels. An ecological multilevel model analysis was performed. GP respondents from European General Practice Research Network (EGPRN) countries, Brazil and New Zeeland. This study included 2543 GPs from 29 countries. GP treatment probability to start or not start antihypertensive treatment based on responses to case-vignettes; either low (GPs (76%) responding to all vignettes, 787 (40%) scored high treatment probability and 1160 (60%) scored low. GPs in high CVD burden countries had higher odds of treatment probability (OR 3.70; 95% confidence interval (CI) 3.00-4.57); in countries with low life expectancy at 60, CVD was associated with high treatment probability (OR 2.18, 95% CI 1.12-4.25); but not in countries with high life expectancy (OR 1.06, 95% CI 0.56-1.98). GPs' choice to treat/not treat hypertension in oldest-old was explained by differences in country-specific health characteristics. GPs in countries with high CVD burden and low life expectancy at age 60 were most likely to treat hypertension in oldest-old. Key Points  • General practitioners (GPs) are in a clinical dilemma when deciding whether (or not) to treat hypertension in the oldest-old (>80 years of age).  • In this study including 1947 GPs from 29 countries, we found that a high country-specific cardiovascular disease (CVD) burden (i.e. myocardial infarction and/or stroke) was associated with a higher GP treatment probability in patients aged >80 years.  • However, the association was modified by country-specific life expectancy at age 60.

Full Text Available    BACKGROUND: Hypertension is one of the most important, worldwide chronic diseases. In most cases the real cause of hypertension is not clear but recent studies have shown that unhealthy lifestyle may lead to stress, anxiety and hypertension.    METHODS: The study design of this article was written based on reviewing published articles in scientific database including ISI web of knowledge, Medline, pub med, Elsevier. The articles about healthy lifestyle, stress and anxiety in patients with hypertension was reviewed.    RESULTS: Hypertension was the major risk factor for developing cardiovascular and renal disease. In most cases the real cause of hypertension was not clear but recent studies have shown that unhealthy lifestyle may lead to stress, anxiety and hypertension. Lifestyle factors were critical determinants of blood pressure levels operating against a background of genetic susceptibility. An improving healthy lifestyle behavior was important in improving health and was a multidimensional pattern. Not all strategies would be effective for every individual, but to some extent all patients being treated for hypertension should incorporate elements of therapeutic lifestyle changes into their treatment regimen. Healthcare providers play an important role in teaching individuals with hypertension on health promotion program and healthy lifestyles. Not only healthcare providers, advice that controlling hypertension is integral, but also patients should follow that advice. Special attention must be paid to intervention programs aimed at modifying lifestyle and providing education on stress management techniques. Non pharmacologic interventions include methods to modify lifestyle and reduce or coping with stress and anxiety such as: stress management intervention (SMI, dietary sodium reduction, weight reduction, supplement regimens utilizing calcium, magnesium, fish oil, and potassium.    CONCLUSION: Several studies in the context of

2015-01-01

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

The American College of Cardiology (ACC) and the American Heart Association (AHA) have recently published their guidelines for the prevention, detection, evaluation, and management of hypertension in adults. The most controversial issue is the classification threshold at 130/80mmHg, which will allow a large number of patients to be diagnosed as hypertensive who were previously considered normotensive. Blood pressure (BP) is considered normal (<120mmHg systolic and <80mmHg diastolic), elevated (120-129 and <80mmHg), stage 1 (130-139 or 80-89mmHg), and stage 2 (≥140 or ≥90mmHg). Out-of-office BP measurements are recommended to confirm the diagnosis of hypertension and for titration of BP-lowering medication. In management, cardiovascular risk would be determinant since those with grade 1 hypertension and an estimated 10-year risk of atherosclerotic cardiovascular disease ≥10%, and those with cardiovascular disease, chronic kidney disease and/or diabetes will require pharmacological treatment, the rest being susceptible to non-pharmacological treatment up to the 140/90mmHg threshold. These recommendations would allow patients with level 1 hypertension and high atherosclerotic cardiovascular disease to benefit from pharmacological therapies and all patients could also benefit from improved non-pharmacological therapies. However, this approach should be cautious because inadequate BP measurement and/or lack of systematic atherosclerotic cardiovascular disease calculation could lead to overestimation in diagnosing hypertension and to overtreatment. Guidelines are recommendations, not impositions, and the management of hypertension should be individualized, based on clinical decisions, preferences of the patients, and an adequate balance between benefits and risks.

To date, few studies have used ambulatory pressure monitoring (ABPM) in patients with chronic kidney disease (CKD) before the start of dialysis treatment. The aim of this study was therefore to ascertain the correlates of arterial hypertension assessed by ABPM in CKD patients at their first referral to a nephrologist. We studied 244 (164 men; mean age 63 years) nondiabetic patients with CKD. Each patient had blood pres-sure (BP) measured by 24-hour ABPM, creatinine clearance (CrCl) estimated according to the Cockcroft-Gault formula, and Hgb concentration, serum lipids, iPTH, daily urinary protein (Uprot) and sodium (UNa) excretion assessed using routine methods. According to ABPM data analysis, 81 patients were normotensives, 78 were stable hypertensives, 26 had day-time hypertension and 59 had nocturnal hypertension. ANOVA showed both lower CrCl (p=0.0033), and higher Uprot (p nighttime SBP > 24-hour PP > daytime PP > daytime SBP > 24-hour SBP. In CKD patients, proteinuria is the strongest correlate of arterial hypertension and particularly of increased nocturnal PP, possibly as an expression of vascular damage. On the basis of these results, ABPM appears to be the most reliable tool for detecting the associations between raised BP (particularly nighttime hypertension) and renal damage in CKD patients not yet on renal replacement therapy (RRT).

2016-09-01

The exercise definition of pulmonary hypertension using a mean pulmonary artery pressure threshold of greater than 30 mmHg was abandoned following the 4th World Pulmonary Hypertension Symposium in 2008, as this definition was not supported by evidence and healthy individuals frequently exceed this threshold. Meanwhile, the clinical value of exercise pulmonary hemodynamic testing has also been questioned. Recent data support the notion that an abnormal pulmonary hemodynamic response during exercise (or exercise pulmonary hypertension) is associated with symptoms and exercise limitation. Pathophysiologic mechanisms accounting for the development of exercise pulmonary hypertension include increased vascular resistance, excessive elevation in left atrial pressure and/or increased volume of trapped air during exercise, resulting in a steep rise in pulmonary artery pressure relative to cardiac output. Recent evidence suggests that exercise pulmonary hypertension may be defined by a mean pulmonary artery pressure surpassing 30 mmHg together with a simultaneous total pulmonary resistance exceeding 3 WU. Exercise pulmonary hypertension is a clinically relevant entity and an improved definition has been suggested based on new evidence. Exercise pulmonary hemodynamics may help unmask early or latent disease, particularly in populations that are at high risk for the development of pulmonary hypertension.

Pulmonary arterial hypertension (PAH) is a distinct subgroup of pulmonary hypertension that comprises idiopathic PAH, familial/heritable forms, and PAH associated with connective tissue disease, congenital heart disease, portal hypertension, human immunodeficiency virus (HIV) infection, and some other conditions. The hemodynamic definition of PAH was recently revised: PAH is now defined by a mean pulmonary artery pressure at rest > or =25 mm Hg in the presence of a pulmonary capillary wedge pressure or =30 mm Hg during exercise) that was used in the old definition of PAH has been removed because there are no robust data that would allow defining an upper limit of normal for the pulmonary pressure during exercise. The revised classification of pulmonary hypertension still consists of five major groups: (1) PAH, (2) pulmonary hypertension due to left heart disease, (3) pulmonary hypertension due to chronic lung disease and/or hypoxia, (4) chronic thromboembolic pulmonary hypertension, and (5) miscellaneous forms. Modifications have been made in some of these groups, such as the addition of schistosomiasis-related pulmonary hypertension and pulmonary hypertension in patients with chronic hemolytic anemia to group 1.

Hepatopulmonary syndrome (HPS) and portopulmonary hypertension (POPH) are two frequent pulmonary complications of liver disease. Portal hypertension is a key element in the pathogenesis of both disorders, which are however distinct in terms of pathogenesis, diagnosis and treatment. HPS corresponds to an abnormal arterial oxygenation in relation with the development of intrapulmonary vascular dilatations. POPH is a pulmonary arterial hypertension in the setting of portal hypertension and elevated pulmonary vascular resistance. As both diseases are associated with an increased risk of morbidity and mortality, it is important to screen and evaluate the severity of these two disorders particularly in liver transplant candidates.

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

Exercise may be an important treatment for hypercholesterolemic patients, particularly in statin users who are at increased diabetes risk. We therefore used Cox proportional hazard analyses to compare running and walking dose (metabolic equivalent hours/day [MET-h/d]) to diabetes, hypertension, and cardiovascular disease (CVD) risk in hypercholesterolemic patients. There were 60 diabetic- and 373 CVD-related deaths during a 10.1-year mortality surveillance of 6,688 hypercholesterolemic patients. In addition, there were 177 incident nonfatal diabetes, 815 incident nonfatal hypertensions, and 323 incident nonfatal CVD events during a 6.4-year follow-up of 6,971 hypercholesterolemic patients who supplied follow-up questionnaires. Fatal and nonfatal diabetes risk decreased 26% (p = 0.002) and 19% (p ≤0.0001) per MET-h/d, respectively, and relative to hypertension risk decreased 4% (p = 0.01) per MET-h/d, and relative to diabetes, hypertension, and CVD risk in hypercholesterolemic patients and should more than compensate for the purported 9% increase in diabetes risk from statin use. By preventing morbidity and mortality for a specific existing medical condition, some exercise expenses may qualify for flexible spending account expenditures in hypercholesterolemic patients when prescribed by a physician.

2016-01-01

The term idiopathic noncirrhotic portal hypertension (INCPH) has been recently proposed to replace terms, such as hepatoportal sclerosis, idiopathic portal hypertension, incomplete septal cirrhosis, and nodular regenerative hyperplasia, used to describe patients with a hepatic presinusoidal cause of portal hypertension of unknown etiology, characterized by features of portal hypertension (esophageal varices, nonmalignant ascites, porto-venous collaterals), splenomegaly, patent portal, and hepatic veins and no clinical and histological signs of cirrhosis. Physicians should learn to look for this condition in a number of clinical settings, including cryptogenic cirrhosis, a disease known to be associated with INCPH, drug administration, and even chronic alterations in liver function tests. Once INCPH is clinically suspected, liver histology becomes mandatory for the correct diagnosis. However, pathologists should be familiar with the histological features of INCPH, especially in cases in which histology is not only requested to exclude liver cirrhosis.

Full Text Available OBJECTIVES AND BACKGROUND Patients with chronic kidney disease (CKD represent a special category of risk. As part of the renal and cardiovascular continuum from risk factors to terminal phase diseases, they develop clinical syndromes with potentially severe prognosis. The aim of this study was to assess the echocardiographic parameters and different responses to treatment in dialysed patients. MATERIALS AND METHODS We examined a number of 1200 dialysed patients (DP with a mean follow-up of 3 years RESULTS Patients on dialysis have severe cardiac risk, an intense atherogenic hyperlipidemic profile, phosphocalcic metabolic alterations and thus a higher rate of atheroma development and occurrence of degenerative valve diseases. These patients are knon to have higher cardiovascular mortality and morbidity and are potential candidates for aggressive reduction of risk factors. Unlike hypertrophy, angiogenesis develops gradually, therefore, oxygen diffusion is prolonged at least 25%. Even mild renal failure is associated with a decreased coronary flow reserve in patients with non-obstructive CAD. This reserve decreases once more in hypertensive DP. Microvascular remodeling determins a reduction in the number of capilary vessels. As a result, DPs are exposed to higher risk for the occurrence of ischemic events and cardiac arrhythmia. The administration of ACE inhibitors and betablockers at the highest tolerated dose decreased cardiovascular morbidity and mortality and improved life quality. Moreover, small doses of these drugs proved to be effective even in patients where hemodialysis alone was enough to control blood pressure. CONCLUSIONS 1. Efficient hemodialysis procedure represents one step in order to control high blood pressure; however, LV hypertrophy in hypertensive dialysed patients (DPs has some particularities 2. The use of ACE inhibitors decreased hypertrophy and improved diastolic filling 3. Blood pressure and electrolyte control

Sex differences in primary hypertension

2012-01-01

Men have higher blood pressure than women through much of life regardless of race and ethnicity. This is a robust and highly conserved sex difference that it is also observed across species including dogs, rats, mice and chickens and it is found in induced, genetic and transgenic animal models of hypertension. Not only do the differences between the ovarian and testicular hormonal milieu contribute to this sexual dimorphism in blood pressure, the sex chromosomes also play a role in and of themselves. This review primarily focuses on epidemiological studies of blood pressure in men and women and experimental models of hypertension in both sexes. Gaps in current knowledge regarding what underlie male-female differences in blood pressure control are discussed. Elucidating the mechanisms underlying sex differences in hypertension may lead to the development of anti-hypertensives tailored to one's sex and ultimately to improved therapeutic strategies for treating this disease and preventing its devastating consequences.

This study sought to examine the risk factors associated with hypertension among the elderly in Ghana. We focused on the association between chronic diseases, socioeconomic factors, and being hypertensive. Data for the study were drawn from Wave 1 of the 2007/2008 Ghana Study on Global Ageing and Adult Health (SAGE). A binary logit model was used to estimate the effect of other noncommunicable diseases, psychosocial factors, lifestyle factors, and sociocultural and biosocial factors on the elderly being hypertensive. Elderly Ghanaians who had been diagnosed with arthritis, angina, diabetes, and asthma were significantly more likely to be hypertensive. Additionally, those depressed were found to be 1.22 times more likely to be hypertensive. Prevention and control of hypertension are complex and demand multistakeholder collaboration including governments, educational institutions, media, food and beverage industry, and a conscious focus on personal lifestyle factors. © The Author(s) 2015.

Full Text Available OBJECTIVE: To determine correlations between age and metabolic disorders in Parkinson's disease (PD patients. METHODS: This observational cross-sectional study included brief tests for dementia and the Mattis test. Signals of metabolic syndrome were evaluated. RESULTS: There was no significant effect from the presence of hypertension (OR=2.36 for patients under 65 years old and OR=0.64 for patients over 65, diabetes or hypercholesterolemia regarding occurrences of dementia associated with PD (24% of the patients. The study demonstrated that each year of age increased the estimated risk of dementia in PD patients by 9% (OR=1.09; 95%CI: 1.01-1.17. CONCLUSION: There was no evidence to correlate the presence of metabolic syndrome with the risk of dementia that was associated with PD. The study confirmed that dementia in PD is age dependent and not related to disease duration.

Non-communicable diseases, including diabetes mellitus and hypertension, continue to disproportionately burden low- and middle-income countries. However, little research has been done to establish current practices and management of chronic disease in these settings. The objective of this study was to examine current clinical management and identify potential gaps in care of patients with diabetes mellitus and hypertension in the district of Toledo, Belize. The study used a mixed methodology to assess current practices and identify gaps in diabetes mellitus and hypertension care. One hundred and twenty charts of the general clinic population were reviewed to establish disease epidemiology. One hundred and seventy-eight diabetic and hypertensive charts were reviewed to assess current practices. Twenty providers completed questionnaires regarding diabetes mellitus and hypertension management. Twenty-five individuals with diabetes mellitus and/or hypertension answered a questionnaire and in-depth interview. The prevalence of diabetes mellitus and hypertension was 12%. Approximately 51% (n = 43) of patients with hypertension were at blood pressure goal and 26% (n = 21) diabetic patients were at glycemic goal based on current guidelines. Of the patients with uncontrolled diabetes, 49% (n = 29) were on two oral agents and only 10% (n = 6) were on insulin. Providers stated that barriers to appropriate management include concerns prescribing insulin and patient health literacy. Patients demonstrated a general understanding of the concept of chronic illness, however lacked specific knowledge regarding disease processes and self-management strategies. This study provides an initial overview of diabetes mellitus and hypertension management in a diverse patient population in rural Belize. Results indicate areas for future investigation and possible intervention, including barriers to insulin use and opportunities for lifestyle-specific disease education for

AIM: To investigate the association between endogenous hydrogen sulfide (H2S) and portal hypertension as well as its effect on vascular smooth muscle cells. METHODS: Portal hypertension patients were categorized by Child-Pugh score based on bilirubin and albumin levels, prothrombin time, ascites and hepatic encephalopathy. Plasma H2S concentrations and portal vein diameters (PVDs) were compared between portal hypertension patients and control participants, as well as between portal hypertension patients with varying degrees of severity. In addition, we established a rabbit hepatic schistosomiasis portal hypertension (SPH) model and analyzed liver morphology, fibrosis grade, plasma and liver tissue H2S concentrations, as well as cystathionine γ-lyase (CSE) activity and phosphorylated extracellular signal-regulated kinase (pERK)1/2, B cell lymphoma (Bcl)-2 and Bcl-XL expression in portal vein smooth muscle cells, in addition to their H2S-induced apoptosis rates. RESULTS: In portal hypertension patients, endogenous H2S levels were significantly lower than those in healthy controls. The more severe the disease was, the lower were the H2S plasma levels, which were inversely correlated with PVD and Child-Pugh score. Liver tissue H2S concentrations and CSE expression were significantly lower in the SPH rabbit livers compared with the control animals, starting at 3 wk, whereas pERK 1/2 expressions gradually increased 12-20 wk after SPH model establishment. In portal vein smooth muscle cells, increasing H2S levels led to increased apoptosis, while Bcl-2 and Bcl-XL expression decreased. CONCLUSION: H2S prevents vascular restructuring caused by excessive proliferation of smooth muscle cells via apoptosis induction, which helps to maintain normal vascular structures. PMID:24574782

Filipino Americans have high rates of hypertension, yet little research has examined hypertension awareness, treatment, and control in this group. In a community-based sample of hypertensive Filipino American immigrants, we identify 1) rates of hypertension awareness, treatment, and control; and 2) factors associated with awareness, treatment, and control. Cross-sectional analysis of survey data from health screenings collected from 2006 to 2010. A total of 566 hypertensive Filipino immigrants in New York City, New York and Jersey City, New Jersey. Hypertension awareness, treatment, and control. Participants were included in analysis if they were hypertensive, based on: a past physician diagnosis, antihypertensive medication use, and/or high blood pressure (BP) screening measurements. Demographic variables included sex, age, time in the United States, location of residence, and English spoken language fluency. Health-related variables included self-reported health, insurance status, diabetes diagnosis, high cholesterol diagnosis, clinical measures (body mass index [BMI], glucose, and cholesterol), exercise frequency, smoking status, cardiac event history, family history of cardiac event, and family history of hypertension. Among the hypertensive individuals, awareness, treatment, and control rates were suboptimal; 72.1 % were aware of their status, 56.5 % were on medication, and only 21.7 % had controlled BP. Factors related to awareness included older age, worse self-reported health, family history of hypertension, and a diagnosis of high cholesterol or diabetes; factors related to treatment included older age, longer time lived in the United States, and being a non-smoker; having health insurance was found to be the main predictor of hypertension control. Many individuals had other cardiovascular disease (CVD) risk factors; 60.4 % had a BMI ≥25, 12.0 % had at-risk glucose measurements and 12.8 % had cholesterol ≥ 240.

Non-communicable diseases (NCDs) such as hypertension and diabetes are rapidly emerging public health problems worldwide, and they associate with primary open-angle glaucoma (POAG). POAG is the most common cause of irreversible blindness. The most effective ways to prevent glaucoma blindness involve identifying high-risk populations and conducting routine screening for early case detection. This study investigated whether POAG associates with hypertension and diabetes in a Nepalese population. To explore the history of systemic illness, our hospital-based case-control study used non-random consecutive sampling in the general eye clinics in three hospitals across Nepal to enroll patients newly diagnosed with POAG and controls without POAG. The study protocol included history taking, ocular examination, and interviews with 173 POAG cases and 510 controls. Data analysis comprised descriptive and inferential statistics. Descriptive statistics computed the percentage, mean, and standard deviation (SD); inferential statistics used McNemar's test to measure associations between diseases. POAG affected males more frequently than females. The odds of members of the Gurung ethnic group having POAG were 2.05 times higher than for other ethnic groups. Hypertension and diabetes were strongly associated with POAG. The overall odds of POAG increased 2.72-fold among hypertensive and 3.50-fold among diabetic patients. POAG associates significantly with hypertension and diabetes in Nepal. Thus, periodic glaucoma screening for hypertension and diabetes patients in addition to opportunistic screening at eye clinics may aid in detecting more POAG cases at an early stage and hence in reducing avoidable blindness.

Common mental disorders, such as anxiety and depression, are risk factors for mortality among cardiac patients, although this topic has gained little attention in individuals with hypertension. We examined the combined effects of hypertension and common mental disorder on mortality in participants with both treated and untreated hypertension. In a representative, prospective study of 31 495 adults (aged 52.5 ± 12.5 years, 45.7% men) we measured baseline levels of common mental disorder using the 12-item General Health Questionnaire (GHQ-12) and collected data on blood pressure, history of hypertension diagnosis, and medication use. High blood pressure (systolic/diastolic >140/90 mmHg) in study members with an existing diagnosis of hypertension indicated uncontrolled hypertension and, in undiagnosed individuals, untreated hypertension. There were 3200 deaths from all causes [943 cardiovascular disease (CVD)] over 8.4 years follow-up. As expected, the risk of CVD was elevated in participants with controlled [multivariate hazard ratio = 1.63, 95% confidence interval (CI) 1.26-2.12] and uncontrolled (multivariate hazard ratio = 1.57, 95% CI 1.08-2.27) hypertension compared with normotensive participants. Common mental disorder (GHQ-12 score of ≥4) was also associated with CVD death (multivariate hazard ratio = 1.60, 95% CI 1.35-1.90). The risk of CVD death was highest in participants with both diagnosed hypertension and common mental disorder, especially in study members with controlled (multivariate hazard ratio = 2.32, 95% CI 1.70-3.17) hypertension but also in uncontrolled hypertension (multivariate hazard ratio = 1.90, 95% CI 1.18-3.05). The combined effect of common mental disorder was also apparent in participants with undiagnosed (untreated) hypertension, especially for all-cause mortality. These findings suggest that the association of hypertension with total and CVD mortality is stronger when combined with common mental disorder.

Hypertension and cardiovascular disease (CVD) may share a similar pathophysiology. Despite shift workers' CVD excess risk, studies on shift work and hypertension are inconclusive. Blood pressure and shift status for 25,343 autoworkers were obtained from medical check-ups and company registers. Cross-sectional associations modeling the total effect from shift work (day shifts, shift work without nights, rotating shift work with nights, and night shifts) on hypertension were assessed. By sequential adjustments, the influence of behavioral, psychosocial, and physiological factors on the total effect was examined, with subsequent mediation and moderation analyses. Adjusted for confounders, shift work without nights (vs. day shifts) was significantly associated with hypertension (OR 1.15, 95%CI 1.02-1.30). The total effect was mediated by BMI, physical inactivity, and sleep disorders. No moderation of the total effect by behaviors was found. The association between shift work and hypertension seems mainly attributable to behavioral mechanisms. © 2015 Wiley Periodicals, Inc.

Cervical Spondylosis and Hypertension

Abstract Cervical spondylosis and hypertension are all common diseases, but the relationship between them has never been studied. Patients with cervical spondylosis are often accompanied with vertigo. Anterior cervical discectomy and fusion is an effective method of treatment for cervical spondylosis with cervical vertigo that is unresponsive to conservative therapy. We report 2 patients of cervical spondylosis with concomitant cervical vertigo and hypertension who were treated successfully with anterior cervical discectomy and fusion. Stimulation of sympathetic nerve fibers in pathologically degenerative disc could produce sympathetic excitation, and induce a sympathetic reflex to cause cervical vertigo and hypertension. In addition, chronic neck pain could contribute to hypertension development through sympathetic arousal and failure of normal homeostatic pain regulatory mechanisms. Cervical spondylosis may be one of the causes of secondary hypertension. Early treatment for resolution of symptoms of cervical spondylosis may have a beneficial impact on cardiovascular disease risk in patients with cervical spondylosis. PMID:25761188

Diagnosis of hypertension-elevated blood pressure (BP) associated with increased cardiovascular disease (CVD) risk-and its management for decades have been based primarily on single time-of-day office BP measurements (OBPM) assumed representative of systolic (SBP) and diastolic BP (DBP) during the entire 24-hours span. Around-the-clock ambulatory blood pressure monitoring (ABPM), however, reveals BP undergoes 24-hours patterning characterized in normotensives and uncomplicated hypertensives by striking morning-time rise, 2 daytime peaks-one ~2-3 hours after awakening and the other early evening, small midafternoon nadir and 10-20% decline (BP dipping) in the asleep BP mean relative to the wake-time BP mean. A growing number of outcome trials substantiate correlation between BP and target organ damage, vascular and other risks is greater for the ABPM-derived asleep BP mean, independent and stronger predictor of CVD risk, than daytime OBPM or ABPM-derived awake BP. Additionally, bedtime hypertension chronotherapy, that is, ingestion of ≥1 conventional hypertension medications at bedtime to achieve efficient attenuation of asleep BP, better reduces total CVD events by 61% and major events (CVD death, myocardial infarction, ischaemic and haemorrhagic stroke) by 67%-even in more vulnerable chronic kidney disease, diabetes and resistant hypertension patients-than customary on-awaking therapy that targets wake-time BP. Such findings of around-the-clock ABPM and bedtime hypertension outcome trials, consistently indicating greater importance of asleep BP than daytime OBPM or ambulatory awake BP, call for a new definition of true arterial hypertension plus modern approaches for its diagnosis and management. © 2018 Stichting European Society for Clinical Investigation Journal Foundation.

Idiopathic noncirrhotic portal hypertension is a heterogeneous group of diseases characterized by portal hypertension in the absence of cirrhosis. The efficacy and safety of transjugular intrahepatic portosystemic shunt (TIPS) in this population are unknown. The charts of patients with idiopathic noncirrhotic portal hypertension undergoing TIPS in seven centers between 2000 and 2014 were retrospectively reviewed. Forty-one patients were included. Indications for TIPS were recurrent variceal bleeding (n = 25) and refractory ascites (n = 16). Patients were categorized according to the presence (n = 27) or absence (n = 14) of significant extrahepatic comorbidities. Associated conditions were hematologic, prothrombotic, neoplastic, immune, and exposure to toxins. During follow-up (mean 27 ± 29 months), variceal rebleeding occurred in 7/25 (28%), including three with early thrombosis of the stent. Post-TIPS overt hepatic encephalopathy was present in 14 patients (34%). Eleven patients died, five due the liver disease or complications of the procedure and six because of the associated comorbidities. The procedure was complicated by hemoperitoneum in four patients (10%), which was fatal in one case. Serum creatinine (P = 0.005), ascites as indication for TIPS (P = 0.04), and the presence of significant comorbidities (P = 0.01) at the time of the procedure were associated with death. Mortality was higher in patients with significant comorbidities and creatinine ≥100 μmol/L (P portal hypertension who have normal kidney function or do not have severe extrahepatic conditions, TIPS is an excellent option to treat severe complications of portal hypertension.

Resistant Hypertension and Cardiorenovascular Risk

Directory of Open Access Journals (Sweden)

Prkacin Ingrid

2017-06-01

Full Text Available Studies have documented independent contribution of sympathetic activation to the cardiovascular disease continuum. Hypertension is one of the leading modifiable factors. Most if not all the benefit of antihypertensive treatment depends on blood pressure lowering, regardless how it is obtained. Resistant hypertension is defined as blood pressure that remains uncontrolled in spite of the concurrent use of three antihypertensive drugs of different classes. Ideally, one of the three drugs should be a diuretic, and all drugs should be prescribed at optimal dose amounts. Poor adherence to antihypertensive therapy, undiscovered secondary causes (e.g. obstructive sleep apnea, primary aldosteronism, renal artery stenosis, and lifestyle factors (e.g. obesity, excessive sodium intake, heavy alcohol intake, various drug interactions are the most common causes of resistant hypertension. Cardio(renovascular morbidity and mortality are significantly higher in resistant hypertensive than in general hypertensive population, as such patients are typically presented with a long-standing history of poorly controlled hypertension. Early diagnosis and treatment is needed to avoid further end-organ damage to prevent cardiorenovascular remodeling. Treatment strategy includes lifestyle changes, adding a mineralocorticoid receptor antagonist, treatment adherence in cardiovascular prevention and, in case of failure to control blood pressure, renal sympathetic denervation or baroreceptor activation therapy. The comparative outcomes in resistant hypertension deserve better understanding. In this review, the most current approaches to resistant hypertension and cardiovascular risk based on the available literature evidence will be discussed.

Full Text Available Interleukins (IL 2, 6, 10, and C-reactive protein are crucial in arterial hypertension with obesity. Background. To identify the characteristics of inflammatory markers in patients with arterial hypertension and obesity, in accordance with the disease duration. Materials and Methods. The study involved 52 patients with stage II hypertension and obesity, divided in three groups according to the disease duration. In the first group consisted of 19 patients disease duration was 5 years, in the second (18 patients — 6–10 years, and in the third one (15 patients — more than 11 years. The serum levels of inflammatory markers were determined by ELISA. Results. When disease duration is 6–10 years, the IL‑6 level is increased slightly compared to the first group, and then decreased. The content of IL‑2 was increased in the first group by 3.74 times, and further decreased by 3.15 times and 3.04 times, respectively, compared to the controls. Levels of IL‑10 and C-reactive protein have the same tendency, as IL‑6. Conclusions. It was found that levels of interleukin 2, 6, 10, and C-reactive protein are significantly increased in patients with hypertension and obesity (greater levels of pro-inflammatory cytokines than the anti-inflammatory. Lengthening the duration of illness leads to less expressive inflammation that may indicate deeper immunological disorders. Initially increased blood concentration of cytokines and C-reactive protein became significantly reduced under standard therapy, but not significantly different from the controls, except the level of IL‑2.

Hypertensive diseases in pregnancy (HDP) occur in 5-8% of all pregnancies and represent one of the most important causes of maternal and fetal morbidity. Even after a normal pregnancy/delivery adaptation to parenthood is a major challenge. However, a successful adjustment is important for future family health. As pregnancy complications may put additional strain on early parenthood, the current study investigated satisfaction with partnership including factors which determine (dis)satisfaction as well as separation rates after pregnancies complicated by HDP. A total of 737 women after HDP and 624 matched-control women completed a self-administered questionnaire on psycho-social factors in the development of HDP. Free-text answers on satisfaction with partnership were analyzed by conceptual analysis. Women with HDP were significantly less often satisfied with their partnership than control women (76%/81.1%; p reasons for a satisfying marital relationship in women with and without a diagnosis of HDP. HDP represent an additional challenge in family adjustment. Adapted perinatal psycho-social support may help to facilitate the start into family life.

Many of the risk factors for heart disease have recently been shown to develop during childhood such as left ventricular hypertrophy and fibrous plaque lesions. As risk for cardiovascular disease in children and adolescents has risen, sleep duration has decreased, and inadequate sleep in children and adolescents has been found to be associated with cardiovascular disease risk. The aims of this manuscript are to provide an updated systematic review of the literature assessing sleep, hypertension, and cardiovascular risk and evaluate the strength of the evidence based on the available research. A systematic review was conducted using six databases from January 1, 2015 through March 9, 2018. We sought studies which looked at the relationship between sleep duration, sleep timing, or sleep quality and outcome variables of hypertension, inflammation, obesity, glucose or insulin, and lipids in children and adolescents. We found 24 studies which met our criteria. Nine studies included hypertension as an outcome variable; fifteen included obesity; thirteen included glucose or insulin; eight included lipids; and three included measures of inflammation. The existing literature on sleep and cardiovascular disease in children and adolescents is limited and relatively weak. Only one RCT was identified, and the overwhelming majority of studies had a high risk of bias. The strongest evidence of an association with sleep is with obesity, hypertension, and insulin sensitivity. Further research using more standardized methods and objective measures is needed to determine if a causal relationship truly exists between sleep and cardiovascular risk.

Objectives We previously found large variations in general practitioner (GP) hypertension treatment probability in oldest-old (>80 years) between countries. We wanted to explore whether differences in country-specific cardiovascular disease (CVD) burden and life expectancy could explain the differences. Design This is a survey study using case-vignettes of oldest-old patients with different comorbidities and blood pressure levels. An ecological multilevel model analysis was performed. Setting GP respondents from European General Practice Research Network (EGPRN) countries, Brazil and New Zeeland. Subjects This study included 2543 GPs from 29 countries. Main outcome measures GP treatment probability to start or not start antihypertensive treatment based on responses to case-vignettes; either low (80 years of age).  • In this study including 1947 GPs from 29 countries, we found that a high country-specific cardiovascular disease (CVD) burden (i.e. myocardial infarction and/or stroke) was associated with a higher GP treatment probability in patients aged >80 years.  • However, the association was modified by country-specific life expectancy at age 60. While there was a positive association for GPs in countries with a low life expectancy at age 60, there was no association in countries with a high life expectancy at age 60.  • These findings help explaining some of the large variation seen in the decision as to whether or not to treat hypertension in the oldest-old.

A hypertensive response to exercise (HRE; defined as normal clinic blood pressure (BP) and exercise systolic BP (SBP) ≥210 mm Hg in men or ≥190 mm Hg in women, or diastolic BP (DBP) ≥105 mm Hg) independently predicts mortality. The mechanisms remain unclear but may be related to masked hypertension. This study aimed to assess the prevalence of masked hypertension and its association with cardiovascular risk factors, including left ventricular (LV) mass, in patients with a HRE. Comprehensive clinical and echocardiographic evaluation (including central BP, aortic pulse wave velocity by tonometry) and 24-h ambulatory BP monitoring (ABPM) were performed in 72 untreated patients with HRE (aged 54 ± 9 years; 60% male; free from coronary artery disease confirmed by exercise stress echocardiography). Masked hypertension was defined according to guidelines as daytime ABPM ≥135/85 mm Hg and clinic BP hypertension was present in 42 patients (58%). These patients had higher LV mass index (41.5 ± 8.7 g/m(2.7) vs. 35.9 ± 8.5 g/m(2.7); P = 0.01), LV relative wall thickness (RWT; 0.42 ± 0.09 vs. 0.37 ± 0.06; P = 0.004) and exercise SBP (222 ± 17 mm Hg vs. 212 ± 14 mm Hg; P = 0.01), but no significant difference in aortic pulse wave velocity or central pulse pressure (P > 0.05 for both). The strongest independent determinant of LV mass index was the presence of masked hypertension (unstandardized β = 5.6; P = 0.007), which was also independently related to LV RWT (unstandardized β = 0.04; P = 0.03). Masked hypertension is highly prevalent in HRE patients with a normal resting office BP and is associated with increased LV mass index and RWT. Clinicians should consider measuring ABPM or home BP in HRE patients.

to study changes involving cerebral vessels in patients with hypertension and various levels of total cardiovascular risk. One hundred and thirty-four patients underwent CT-angiography of intracranial vessels. Ninety-eight of them were diagnosed with hypertension. Taking into consideration high blood pressure, presence of risk factors and target organ damage subjects were divided into 4 groups: with low, medium, high and very high total cardiovascular risk. Control group included 36 patients. They were not diagnosed with hypertension at the time of examination. One hundred and five patients were examined using a 4-slice CT scanner (Toshiba Asteion 4, Toshiba Medical System, Japan), and 29 patients were examined using a 128-slice scanner (Siemens Definition AS+, Siemens Healthcare, Germany) with an injection system. We used iodine-containing contrast agents such as iodixanol and iopromide for angiography. Anatomical and topographic changes of cerebral vessels were most frequently found in hypertensive patients with high and very high total cardiovascular risk. Narrowing of vertebral vessels was the most common change (27 patients (27.55%), 21 patients (21.43%) had narrowing of the right artery, and 6 (6.12%) subjects – of the left one). Tortuous course of internal carotid arteries at the neck level was visualized in 11 patients (11.22%). Narrowing of A1 segment of anterior cerebral artery was noted in 9 patients (9.18%), of the right one – in 8 patients (8.16%), of the left one – in 1 patient (1.02%). Aneurysmal dilation of intracranial vessels was visualized in 6 patients (6.12%). Saccular aneurysm of left internal carotid artery was diagnosed in 2 patients (2.04%), one patient (1.02%) had right internal carotid artery aneurysm and one patient (1.02%) had an aneurysm of the basilar artery. the most common changes of cerebral vessels diagnosed in MDCTA among patients with hypertension included various degrees of narrowing of vertebral vessels, anterior

Long-term imaging and clinical findings are reported in six children whose polycystic kidney disease was detected in infancy or early childhood. Over time (2 years to 20 years) all patients developed portal hypertension from hepatic fibrosis, a problem primarily noted in recessive pattern polycystic kidney disease. Mild renal failure (two patients) was accompanied by serious systemic hypertension in the same patients. In one family, one of the babies also showed dilated right hepatic ducts. Imaging studies included urography and CT although recently ultrasonography was the method of choice. The relative renal and hepatic manifestations in these patients so changed with time that it would seem fallacious to attempt to use rigid classifications based on findings at initial diagnosis.

Chronic kidney disease (CKD) and hypertension are global public health problems associated with considerable morbidity, premature mortality and attendant healthcare costs. Previous studies have highlighted that non-invasive examination of the retinal microcirculation can detect microvascular pathology that is associated with systemic disorders of the circulatory system such as hypertension. We examined the associations between retinal vessel caliber (RVC) and fractal dimension (DF), with both hypertension and CKD in elderly Irish nuns. Data from 1233 participants in the cross-sectional observational Irish Nun Eye Study (INES) were assessed from digital photographs with a standardized protocol using computer-assisted software. Multivariate regression analyses were used to assess associations with hypertension and CKD, with adjustment for age, body mass index (BMI), refraction, fellow eye RVC, smoking, alcohol consumption, ischemic heart disease (IHD), cerebrovascular accident (CVA), diabetes and medication use. In total, 1122 (91%) participants (mean age: 76.3 [range: 56-100] years) had gradable retinal images of sufficient quality for blood vessel assessment. Hypertension was significantly associated with a narrower central retinal arteriolar equivalent (CRAE) in a fully adjusted analysis (P = 0.002; effect size = -2.16 μm; 95% confidence intervals [CI]: -3.51, -0.81 μm). No significant associations between other retinal vascular parameters and hypertension or between any retinal vascular parameters and CKD were found. Individuals with hypertension have significantly narrower retinal arterioles which may afford an earlier opportunity for tailored prevention and treatment options to optimize the structure and function of the microvasculature, providing additional clinical utility. No significant associations between retinal vascular parameters and CKD were detected.

To assess endothelial dysfunction and the risk for coronary atherosclerosis in children with irreversible pulmonary hypertension due to congenital heart disease (CHD). The study included 18 cyanotic patients (the mean age was 12.28 ± 3.26 years) who developed irreversible pulmonary hypertension due to cyanotic and acyanotic CHDs, and 18 control patients (the mean age was 11.78 ± 3.00 years). Study groups were compared for flow-mediated dilatation (FMD), carotid intima media thickness (CIMT) and atherosclerotic risk factors. Compared to the control group, the mean FMD was significantly reduced in the cyanotic group (5.26 ± 2.42% and 9.48 ± 2.60%, respectively; P-value < 0.001). No significant difference was observed between the groups in CIMT (0.41 ± 0.08 mm and 0.39 ± 0.06 mm, respectively; P-value = 0.299). The levels of total cholesterol, low-density lipoprotein–cholesterol and very low-density lipoprotein–cholesterol were statistically significantly lower compared tothe control group (P-value = 0.001, 0.006 and 0.014, respectively), whereas no statistically significant difference was found in the levels of high-density lipoprotein–cholesterol and triglycerides (P-value = 0.113 and 0.975, respectively). Systemic endothelial dysfunction in children with irreversible pulmonary hypertension due to CHD was noted but there was no increased risk for atherosclerosis

BACKGROUND: The combination of hypertension and high physical activity at work may increase blood pressure considerably and increase the risk of atherosclerosis and thereby ischaemic heart disease (IHD), but only a few studies in men, and none among women, have examined this topic. DESIGN......: This was a prospective cohort study. METHODS: In 1993, 12,093 female nurses from the Danish Nurse Cohort Study, aged 45-64 years answered a baseline questionnaire on physical activity at work, history of hypertension, a selection of known risk factors for IHD and occupational factors. Information on incident IHD from...... baseline to 2008 was retrieved by individual linkage to the National Register of Hospital Discharges. RESULTS: In a fully adjusted Cox model, hypertensive nurses with high physical activity at work had nearly three times higher risk of IHD (hazard ratio (HR) 2.87 (95% confidence interval (CI) 2...

To prevent recurrence of cerebrovascular disease (CVD), adequate control of blood pressure (BP) is extremely important for the treatment of hypertensive CVD patients. As absence of the nocturnal fall of BP by the expected 10-20% from daytime levels is reported to exaggerate target organ injury, 24-h ambulatory blood pressure monitoring (ABPM) was conducted, especially to obtain data during nighttime sleep. Forty-eight elderly bedridden chronic phase CVD hypertensive patients (assessed 1-3 mo after CVD accident) participated. As a group, nocturnal BP was higher than diurnal BP, whereas nocturnal pulse rate was lower than diurnal pulse rate. The nocturnal BP fall was blunted in most (∼90%) of the patients. These results suggest that to perform a rational drug treatment, it is essential to do 24-h ABPM before initiation of antihypertensive therapy in elderly bedridden hypertensive CVD patients.

Despite the availability of efficacious treatments, only half of patients with hypertension achieve adequate blood pressure (BP) control. This paper describes the protocol and baseline subject characteristics of a 2-arm, 18-month randomized clinical trial of titrated disease management (TDM) for patients with pharmaceutically-treated hypertension for whom systolic blood pressure (SBP) is not controlled (≥140mmHg for non-diabetic or ≥130mmHg for diabetic patients). The trial is being conducted among patients of four clinic locations associated with a Veterans Affairs Medical Center. An intervention arm has a TDM strategy in which patients' hypertension control at baseline, 6, and 12 months determines the resource intensity of disease management. Intensity levels include: a low-intensity strategy utilizing a licensed practical nurse to provide bi-monthly, non-tailored behavioral support calls to patients whose SBP comes under control; medium-intensity strategy utilizing a registered nurse to provide monthly tailored behavioral support telephone calls plus home BP monitoring; and high-intensity strategy utilizing a pharmacist to provide monthly tailored behavioral support telephone calls, home BP monitoring, and pharmacist-directed medication management. Control arm patients receive the low-intensity strategy regardless of BP control. The primary outcome is SBP. There are 385 randomized (192 intervention; 193 control) veterans that are predominately older (mean age 63.5 years) men (92.5%). 61.8% are African American, and the mean baseline SBP for all subjects is 143.6mmHg. This trial will determine if a disease management program that is titrated by matching the intensity of resources to patients' BP control leads to superior outcomes compared to a low-intensity management strategy.

Full Text Available Introduction: Human gut microbiota is believed to be directly or indirectly involved in cardiovascular diseases and hypertension. However, the identification and functional status of the hypertension-related gut microbe(s have not yet been surveyed in a comprehensive manner.Methods: Here we characterized the gut microbiome in hypertension status by comparing fecal samples of 60 patients with primary hypertension and 60 gender-, age-, and body weight-matched healthy controls based on whole-metagenome shotgun sequencing.Results: Hypertension implicated a remarkable gut dysbiosis with significant reduction in within-sample diversity and shift in microbial composition. Metagenome-wide association study (MGWAS revealed 53,953 microbial genes that differ in distribution between the patients and healthy controls (false discovery rate, 0.05 and can be grouped into 68 clusters representing bacterial species. Opportunistic pathogenic taxa, such as, Klebsiella spp., Streptococcus spp., and Parabacteroides merdae were frequently distributed in hypertensive gut microbiome, whereas the short-chain fatty acid producer, such as, Roseburia spp. and Faecalibacterium prausnitzii, were higher in controls. The number of hypertension-associated species also showed stronger correlation to the severity of disease. Functionally, the hypertensive gut microbiome exhibited higher membrane transport, lipopolysaccharide biosynthesis and steroid degradation, while in controls the metabolism of amino acid, cofactors and vitamins was found to be higher. We further provided the microbial markers for disease discrimination and achieved an area under the receiver operator characteristic curve (AUC of 0.78, demonstrating the potential of gut microbiota in prediction of hypertension.Conclusion: These findings represent specific alterations in microbial diversity, genes, species and functions of the hypertensive gut microbiome.

2010-03-01

In the last several years, there have been numerous advancements in the field of pulmonary hypertension as a whole, but there have been few changes in the management of children with pulmonary hypertension after cardiac surgery. Patients at particular risk for postoperative pulmonary hypertension can be identified preoperatively based on their cardiac disease and can be grouped into four broad categories based on the mechanisms responsible for pulmonary hypertension: 1) increased pulmonary vascular resistance; 2) increased pulmonary blood flow with normal pulmonary vascular resistance; 3) a combination of increased pulmonary vascular resistance and increased blood flow; and 4) increased pulmonary venous pressure. In this review of the immediate postoperative management of pulmonary hypertension, various strategies are discussed including medical therapies, monitoring, ventilatory strategies, and weaning from these supports. With early recognition of patients at particular risk for severe pulmonary hypertension, management strategies can be directed at preventing or minimizing hemodynamic instability and thereby prevent the development of ventricular dysfunction and a low output state.

2017-01-01

Full Text Available The mechanisms facilitating hypertension in diabetes still remain to be elucidated. Nonalcoholic fatty liver disease (NAFLD, which is a higher risk factor for insulin resistance, shares many predisposing factors with diabetes. However, little work has been performed on the pathogenesis of hypertension in type 2 diabetes (T2DM with NAFLD. The aim of this study is to investigate the prevalence of hypertension in different glycemic statuses and to analyze relationships between NAFLD, metabolic risks, and hypertension within a large community-based population after informed written consent. A total of 9473 subjects aged over 45 years, including 1648 patients with T2DM, were enrolled in this cross-sectional study. Clinical and biochemical parameters of all participants were determined. The results suggested that the patients with prediabetes or T2DM were with higher risks to have hypertension. T2DM with NAFLD had significantly higher levels of blood pressure, triglyceride, uric acid, and HOMA-IR than those without NAFLD. Data analyses suggested that hypertriglyceridemia [OR = 1.773 (1.396, 2.251], NAFLD [OR = 2.344 (1.736, 3.165], hyperuricemia [OR = 1.474 (1.079, 2.012], and insulin resistance [OR = 1.948 (1.540, 2.465] were associated with the higher prevalence of hypertension independent of other metabolic risk factors in type 2 diabetes. Further studies are needed to focus on these associations.

The REgistry of Pulmonary Hypertension Associated with Rheumatic Disease (REOPARD) was established in Korea. The baseline data are described from the second year of the registry's operation. Patients with a connective tissue disease (CTD) who met the modified definition of the WHO group I pulmonary arterial hypertension (PAH) were enrolled. PAH was defined as a systolic pulmonary arterial pressure> 40 mmHg by echocardiography or mean pulmonary arterial pressure> 25 mmHg by right heart catheterization. Hemodynamic parameters and clinical data such as demographics, functional class, underlying disease, organ involvement, laboratory tests and current treatment were recorded. A total of 321 patients were enrolled during the 2-year study period from 2008 to 2010. The mean age of the patients at registration was 51.9 years and 87.5% were female. Most patients were diagnosed by echocardiography and only 24 patients (7.5%) underwent cardiac catheterization. Exertional dyspnea was present in 63.6% of patients and 31.8% were New York Heart Association class III or IV. Among the patients, systemic lupus erythematosus accounted for 35.3%, systemic sclerosis 28.3%, rheumatoid arthritis 7.8%, overlap syndrome 9.0%, and mixed connective tissue disease 5.9%. There were no significant differences in hemodynamics, functional class, diffusing capacity and N-terminal pro-brain natriuretic peptide levels between the disease subgroups. Treatments consisted of calcium antagonists (57.0%), endothelin antagonists (32.7%), prostanoids (27.1%), phosphodiesterase-5 inhibitors (14.3%) and combinations (37.4%). Compared with previous studies, the results showed some differences: underlying diseases, functional status and treatments. This may be due to differences in ethnic background and diagnostic methods of our study. © 2012 The Authors International Journal of Rheumatic Diseases © 2012 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd.

Full Text Available Although liver cirrhosis is the most common cause of portal hypertension (PH, about 20% of PH cases are caused by non-cirrhotic reasons, which are referred to as non-cirrhotic portal hypertension (NCPH, with a high incidence rate in developing countries. NCPH is a group of heterogeneous hepatic vascular diseases, including idiopathic portal hypertension (IPH and extrahepatic portal vein obstruction (EHPVO, as well as the rare diseases in clinical practice such as Budd-Chiari syndrome, congenital hepatic fibrosis, and nodular regenerative hyperplasia. The patients with NCPH usually have the symptoms of portal hypertension, such as recurrent variceal bleeding and splenomegaly, but liver function is well preserved in these patients. At present, the diagnosis of NCPH lacks a universally accepted standard and remains a challenge. In clinical practice, the method of exclusion is usually applied for the diagnosis of HCPH, and liver biopsy is performed when necessary to make a confirmed diagnosis. This paper introduces the pathogenesis and pathological manifestations of IPH and EHPVO, as well as the selection of diagnostic methods and therapeutic strategies. If upper gastrointestinal bleeding can be effectively controlled, NCPH is considered to have a relatively good prognosis.

Congenital diaphragmatic hernia-associated pulmonary hypertension.

2017-06-01

Congenital diaphragmatic hernia (CDH) is a complex entity wherein a diaphragmatic defect allows intrathoracic herniation of intra-abdominal contents and both pulmonary parenchymal and vascular development are stifled. Pulmonary pathology and pathophysiology, including pulmonary hypoplasia and pulmonary hypertension, are hallmarks of CDH and are associated with disease severity. Pulmonary hypertension (PH) is sustained, supranormal pulmonary arterial pressure, and among patients with CDH (CDH-PH), is driven by hypoplastic pulmonary vasculature, including alterations at the molecular, cellular, and tissue levels, along with pathophysiologic pulmonary vasoreactivity. This review addresses the basic mechanisms, altered anatomy, definition, diagnosis, and management of CDH-PH. Further, emerging therapies targeting CDH-PH and PH are explored.

Adusumalli, Srinath; Mazurek, Jeremy A

2017-12-01

The purpose of this review is to define pulmonary hypertension in the setting of left heart disease (PH-LHD), discuss its epidemiology and pathophysiology, and highlight the cause and effect relationship it has with disease progression in the setting of cardiomyopathy. Both pulmonary hypertension (PH) and heart failure are becoming increasingly common. As such, PH-LHD is now the most common form of PH. The pathophysiology of the condition relates to backward transmission of elevated left ventricular filling pressures into the pulmonary circulation and, ultimately, right ventricular (RV) strain/dysfunction. It is evident that these pathophysiologic processes are both the effect and cause of left heart disease progression. In this review, we describe the complex relationship between disease progression in left ventricular cardiomyopathy and PH-LHD. Clinicians and researchers should take note of the importance of PH-LHD and RV dysfunction to appropriately risk stratify patients and develop therapies for the condition.

Gut flora has personal characteristics for each individual, similar to the fingerprints, consisting of a special mixture of bacterial species living in the intestines, now referred to as the gut microbiome. There is a strong correlation between the loss of microbial diversity and the functional bowel disorders, obesity, type 2 diabetes and cardiovascular disease as well as many autoimmune disorders. With genetic testing of stool diversity of the gut microbiome and exact analysis of the species and phylogenetic classification of the gut flora, the changes of diversity can be identified and the overgrowth of some bacteria can be revealed. In cases with pre- and manifest hypertension, an overgrowth of species from the phylum Firmicutes has been reported along with the relative decline of the phylum Bacteroidetes as opposed with cases of normotension. At the same time, the physiological balance among bacterial families was lost. According to the first studies, there is a correlation between hypertension and the lost balance of the gut microflora, both in animal experiments and in the human clinical setting. This evidence also suggests that targeted dietary alteration of the gut microbiome can be a new innovative approach in the treatment of hypertension. Orv Hetil. 2018; 159(9): 346-351.

Autosomal dominant polycystic kidney disease is the most common inheritable kidney disease, frequently thought to become symptomatic in adulthood. However, patients with autosomal dominant polycystic kidney disease may develop signs or symptoms during childhood, in particular hypertension. Although ambulatory BP monitoring is the preferred method to diagnose hypertension in pediatrics, data in children with autosomal dominant polycystic kidney disease are limited. Our retrospective multicenter study was conducted to collect ambulatory BP monitoring recordings from patients with autosomal dominant polycystic kidney disease age 1 cm per kidney and daytime hypertension (odds ratio, 1.70; 95% confidence interval, 1.21 to 2.4; P =0.002), nighttime hypertension (odds ratio, 1.31; 95% confidence interval, 1.05 to 1.63; P =0.02), or 24-hour hypertension (odds ratio, 1.39; 95% confidence interval, 1.08 to 1.81; P =0.01). Kidney length, expressed as SD score, was also significantly associated with nighttime hypertension (odds ratio, 1.23; 95% confidence interval, 1.06 to 1.42; P =0.10). These data indicate high prevalence of hypertension in children with autosomal dominant polycystic kidney disease starting at young ages. Copyright © 2018 by the American Society of Nephrology.

Hypertension-attributed nephropathy: what's in a name?

Science.gov (United States)

Freedman, Barry I; Cohen, Arthur H

2016-01-01

Unrelated disease processes commonly occur in non-diabetic individuals with mild-to-moderate hypertension and low level or absent proteinuria who present with chronic kidney disease: primary glomerulosclerosis in those with recent African ancestry, and arteriolar nephrosclerosis with resultant glomerular ischaemia potentially related to hypertension and vascular disease risk factors in other cases. Unfortunately, nephrologists often indiscriminately apply a diagnosis of 'hypertensive nephrosclerosis' to patients in either scenario, which implies that the hypertension is causative of their renal disease. Although nephropathies that are associated with variants in the apolipoprotein L1 gene (APOL1) often cause secondarily elevated blood pressure, they belong to the spectrum of focal segmental glomerulosclerosis and are not initiated by systemic hypertension. Because genetic testing for APOL1 variants and other glomerulosclerosis-associated gene variants is available and can provide a precise definition of disease pathogenesis, we believe that the term 'hypertensive nephrosclerosis' should now be abandoned and replaced with either gene-based (for example, APOL1-associated) glomerulosclerosis or arteriolar nephrosclerosis. Precision medicine will be key to improving diagnostic accuracy in this field. Discrimination of these disparate disorders has the potential to eradicate primary forms of glomerulosclerosis that are associated with APOL1 renal-risk variants.

Presence of an interaction between smoking and being overweight increases risks of hypertension, diabetes, and cardiovascular disease in outpatients with mood disorders.

We aimed to evaluate the hypothesis that the presence of an interaction between smoking and being overweight increases the risks of lifestyle-related diseases (hypertension, diabetes mellitus, dyslipidemia, and cardiovascular disease) in outpatients with mood disorders. In this cross-sectional survey, using data from 213 outpatients with mood disorders (95 men, 118 women), we calculated the adjusted odds ratios (ORs) with 95% confidence intervals (CIs) for each of hypertension, diabetes, dyslipedemia, and cardiovascular disease, using a binary logistic regression model; we then calculated the adjusted OR values for smokers and non-smokers with body mass indexes (BMIs) of <25 or ≥25 kg/m². Next, we examined the data for the presence of an interaction between smoking and being overweight, using three measures of additive interaction: relative excess risk due to the interaction (RERI), attributable proportion due to the interaction (AP), and the synergy index (S). Smokers with BMI <25 kg/m² had a significantly lower risk of hypertension (OR 0.27, 95% CI 0.09-0.81) than non-smokers with BMI <25 kg/m² (reference group). Compared with the reference group, overweight non-smokers had a significantly higher risk (2.82, 1.34-6.19) of hypertension, and overweight smokers had a higher risk (4.43, 1.28-15.26) of hypertension and very high risks of diabetes (8.24, 2.47-27.42) and cardiovascular disease (13.12, 1.95-88.41). The highest RERI was derived from the relation with cardiovascular disease. The highest AP and S were derived from the relation with type 2 diabetes. There was no interaction of smoking and being overweight with dyslipidemia. The presence of an interaction between smoking and being overweight exacerbates the risks of hypertension, diabetes, and cardiovascular disease in outpatients with mood disorders.

Albuminuria and masked uncontrolled hypertension in chronic kidney disease.

Agarwal, Rajiv

Masked uncontrolled hypertension (MUCH) is associated with greater target organ damage such as left ventricular hypertrophy, increased arterial stiffness and albuminuria. Whether MUCH independently associates with greater cardiovascular end-organ damage or kidney damage is unclear. The objective of this study was to assess the strength of the relationship of MUCH (awake ambulatory blood pressure ≥135/85 mmHg and clinic blood pressure <140/90 mmHg) with target organ damage. In a cross-sectional study at a veterans' administration medical center, clinically normotensive veterans without chronic kidney disease (CKD) (n = 29) and 287 patients with CKD and controlled hypertension (CH, n = 193), MUCH (n = 67) and uncontrolled hypertension (UCH, n = 27) had evaluation of target organ damage. Target organ damage was measured by echocardiography [left ventricular mass index (LVMI)], arterial ultrasonography [aortic pulse wave velocity (PWV)] and 24-h urine collection [albuminuria (urine albumin to creatinine ratio)] in all participants. Compared to that of controls, LVMI was higher by 21.8 g/m2 (CI, 4.0-39.7 g/m2) in CH, 27.9 (CI, 8-47.8) in MUCH and 39.5 (CI, 15.7-63.2) in UCH (P < 0.01 for group differences, P < 0.01 for linear trend). Although differences persisted after adjustment for age, sex and race, they lost significance after adjustments for cardiovascular risk factors and their treatment. Compared to that of controls, PWV was different among CH, MUCH and UCH (P = 0.04 for group differences, P = 0.02 for linear trend). However, differences lost significance after adjustments for age, sex and race. Compared to that of controls, log2 UACR was higher by 2.40 mg/mg (CI, 1.28-3.52) in CH, 4.94 (CI, 3.70-6.18) in MUCH and 6.01 (CI, 4.49-7.53) in UCH (P < 0.0001 for group difference, P < 0.0001 for linear trend). Differences persisted after adjustment for age, sex and race, cardiovascular risk factors and their treatment and cardiovascular disease (P < 0.0001 for group

It is accepted that patient education can be beneficial in the treatment of chronic diseases. We conducted an educational intervention (EI) in hypertensive patients seen at Primary Care centres (PCC) and specialised Hypertension Units (SHU). To assess patient's knowledge of hypertension and to verify the impact of this educational initiative. A multicentre quasi-experimental study with the participation of 120 patients with hypertension. EI consisted of oral and written information which included the definition of hypertension, causes, cardiovascular risk factors and means of control. A self-administered questionnaire was used to assess patient's knowledge before and after EI. Sixty-two (52%) patients were from PCC and 58 (48%) from SHU (mean age: 61 ± 13.3 years, 59% were women). There were no differences in baseline characteristics between patients attending at PCC and SHU. The definition of hypertension (blood pressure ≥140 mmHg and/or ≥90 mmHg was known by 48% and 99% of the participants before and after EI, respectively (p hypertension was related to kidneys (54%) and eyes (58%). After EI this knowledge increased to 100% (p hypertension. However, further studies are needed to assess if EI produces behaviour changes in the long term, as this might enhance optimal blood pressure control to prevent kidney disease or delay its progression. © 2016 European Dialysis and Transplant Nurses Association/European Renal Care Association.

Preliminary studies of pulmonary perfusion scanning in patients with pulmonary hypertension

1986-01-01

A comparative analysis of pulmonary perfusion scanning through cardiac catheterization of 57 patients including 32 patients with congenital heart disease, 8 patients with chronic pulmonary thromboembolism and 7 patients with primary pulmonary hypertension is reported. The lung scintigram obtained with In-113m or Tc-99m-MAA represents the distribution of pulmonary blood. It has been found that the lung scintigram was abnormal in patients of congenital heart disease with pulmonary hypertension (i. e. pulmonary artery pressure between 41-80 mmHg) and the extent of radoiactive regional defects is proportional to the level of pulmonary hypertension. The results of the analysis indicated that pulmonary perfusion scanning being a noninvasive technique would be a useful method in evaluating the level of pulmonary hypertension in patients with left to right shunt before and after surgical operation

Precision Medicine for Hypertension Management in Chronic Kidney Disease: Relevance of SPRINT for Therapeutic Targets in Nondiabetic Renal Disease.

Ruzicka, Marcel; Burns, Kevin D; Hiremath, Swapnil

2017-05-01

In this review we evaluate the literature to determine if lower blood pressure (BP) targets are beneficial for patients with nondiabetic chronic kidney disease (CKD). Modification of Diet in Renal Disease (MDRD), African American Study of Kidney Disease and Hypertension (AASK), and Ramipril Efficacy in Nephropathy-2 (REIN-2), designed to assess the benefit of lower BP on progression of nondiabetic CKD, generally came to the same negative conclusion. They were not designed and powered to assess an effect of lower BP on cardiovascular outcomes. The Systolic Blood Pressure Intervention Trial (SPRINT) was the first trial designed and powered to address this issue, and showed a clear benefit of a lower targeted and achieved BP. SPRINT did not show any renal benefits from lower BP, and it was not designed to assess this outcome, and it enrolled patients with less "renal risk" per se. A distinguishing feature of SPRINT compared with other large trials is that it highlighted the importance of precise BP measurement methods in defining targets in hypertension treatment. Accordingly, we propose that SPRINT is truly a "game-changing" clinical trial that sets the bar for management of hypertension in select patients with nondiabetic CKD. In these patients, systolic BP target depends critically on the BP measurement method: < 140 mm Hg when derived from 3 readings using a mercury sphygmomanometer after 5 minutes of rest, < 130 mm Hg when calculated from at a minimum of 3 readings using an automated oscillometric device, and < 120 mm Hg when taken using an automated oscillometric device after 5 minutes of unattended rest.

Walters, Arthur S; Rye, David B

2009-05-01

Evidence is reviewed documenting an intimate relationship among restless legs syndrome (RLS) / periodic limb movements in sleep (PLMS) and hypertension and cardiovascular and cerebrovascular disease. Sympathetic overactivity is associated with RLS/PLMS, as manifested by increased pulse rate and blood pressure coincident with PLMS. Causality is far from definitive. Mechanisms are explored as to how RLS/PLMS may lead to high blood pressure, heart disease, and stroke: (a) the sympathetic hyperactivity associated with RLS/PLMS may lead to daytime hypertension that in turn leads to heart disease and stroke; (b) in the absence of daytime hypertension, this sympathetic hyperactivity may predispose to heart disease and stroke either directly or indirectly via atherosclerotic plaque formation and rupture; and (c) comorbidities associated with RLS/PLMS, such as renal failure, diabetes, iron deficiency, and insomnia, may predispose to heart disease and stroke. One theoretical cause for sympathetic hyperactivity is insufficient All diencephalospinal dopaminergic neuron inhibition of sympathetic preganglionic neurons residing in the intermediolateral cell columns of the spinal cord. We cannot exclude the possibility that peripheral vascular, cardiovascular, and cerebrovascular disease may also contribute to RLS/PLMS, and mechanisms for these possibilities are also discussed.

Objective: To investigate the impact of blood pressure and age on arterial stiffness in general population. Methods: Participants who took part in 2010, 2012 and 2014 Kailuan health examination were included. Data of brachial ankle pulse wave velocity (baPWV) examination were analyzed. According to the WHO criteria of age, participants were divided into 3 age groups: 18-44 years group ( n= 11 608), 45-59 years group ( n= 12 757), above 60 years group ( n= 5 002). Participants were further divided into hypertension group and non-hypertension group according to the diagnostic criteria for hypertension (2010 Chinese guidelines for the managemengt of hypertension). Multiple linear regression analysis was used to analyze the association between systolic blood pressure (SBP) with baPWV in the total participants and then stratified by age groups. Multivariate logistic regression model was used to analyze the influence of blood pressure on arterial stiffness (baPWV≥1 400 cm/s) of various groups. Results: (1)The baseline characteristics of all participants: 35 350 participants completed 2010, 2012 and 2014 Kailuan examinations and took part in baPWV examination. 2 237 participants without blood pressure measurement values were excluded, 1 569 participants with history of peripheral artery disease were excluded, we also excluded 1 016 participants with history of cardiac-cerebral vascular disease. Data from 29 367 participants were analyzed. The age was (48.0±12.4) years old, 21 305 were males (72.5%). (2) Distribution of baPWV in various age groups: baPWV increased with aging. In non-hypertension population, baPWV in 18-44 years group, 45-59 years group, above 60 years group were as follows: 1 299.3, 1 428.7 and 1 704.6 cm/s, respectively. For hypertension participants, the respective values of baPWV were: 1 498.4, 1 640.7 and 1 921.4 cm/s. BaPWV was significantly higher in hypertension group than non-hypertension group of respective age groups ( Page groups ( t -value

Sex differences in T cells in hypertension.

Tipton, Ashlee J; Sullivan, Jennifer C

2014-12-01

Hypertension is a major risk factor for cardiovascular disease, stroke, and end-organ damage. There is a sex difference in blood pressure (BP) that begins in adolescence and continues into adulthood, in which men have a higher prevalence of hypertension compared with women until the sixth decade of life. Less than 50% of hypertensive adults in the United States manage to control their BP to recommended levels using current therapeutic options, and women are more likely than are men to have uncontrolled high BP. This, is despite the facts that more women compared with men are aware that they have hypertension and that women are more likely to seek treatment for the disease. Novel therapeutic targets need to be identified in both sexes to increase the percentage of hypertensive individuals with controlled BP. The purpose of this article was to review the available literature on the role of T cells in BP control in both sexes, and the potential therapeutic application/implications of targeting immune cells in hypertension. A search of PubMed was conducted to determine the impact of sex on T cell-mediated control of BP. The search terms included sex, gender, estrogen, testosterone, inflammation, T cells, T regulatory cells, Th17 cells, hypertension, and blood pressure. Additional data were included from our laboratory examinations of cytokine expression in the kidneys of male and female spontaneously hypertensive rats (SHRs) and differential gene expression in both the renal cortex and mesenteric arterial bed of male and female SHRs. There is a growing scientific literature base regarding the role of T cells in the pathogenesis of hypertension and BP control; however, the majority of these studies have been performed exclusively in males, despite the fact that both men and women develop hypertension. There is increasing evidence that although T cells also mediate BP in females, there are distinct differences in both the T-cell profile and the functional impact of sex

Full Text Available To evaluate the prevalence, etiologic factors and therapy of hypertension in actively followed up transplant population in Saudi Arabia; we retrospectively reviewed the records of the active renal transplant patients at two large transplant centers in Riyadh and Jeddah in Saudi Arabia. These subjects were transplanted between January 1979 and November 1998. The patients were grouped according to the measurement of blood pressure; group 1 (considered normo-tensive: blood pressure below 140/90 mmHg, group2: blood pressure between 140-159/90-99, group 3: blood pressure 160-179/100-109 group 4: equal to or above 180/110. There were 1115 patients′ records included in the study. The mean duration of transplantation was 66.9 ± 50.1 months. According to the level of measured blood pressure, there were 641 (57.5% patients in the normotensive group (group 1, 404 (36.3% patients in the mildly hypertensive group (group 2 64 (5.7% patients in the moderately severe hypertension group (group 3 and only six (0.5% patients in the severe hypertension group (group 4. The estimated prevalence of hypertension in this study was almost 85%. We found no significant difference in the prevalence of hypertension in terms of gender, year of transplantation, duration of transplantation, type of donor, number of previous transplants, diagnosis of renal artery stenosis, etiology of kidney disease, diagnosis of diabetes after transplantation, diagnosis of cerebrovascular accidents, or mean dose of prednisolone and cyclosporine. There was a statistically significant association between increased level of blood pressure and old age (above 50 years, original disease associated with hypertension, history of hypertension on dialysis, acute rejection (once or more, presence of protienuria (more than 0.3 mg/day, abnormality of ECG, or serum creatinine above 300 µmol/L.

Full Text Available Chronic kidney disease (CKD and hypertension are global public health problems associated with considerable morbidity, premature mortality and attendant healthcare costs. Previous studies have highlighted that non-invasive examination of the retinal microcirculation can detect microvascular pathology that is associated with systemic disorders of the circulatory system such as hypertension. We examined the associations between retinal vessel caliber (RVC and fractal dimension (DF, with both hypertension and CKD in elderly Irish nuns.Data from 1233 participants in the cross-sectional observational Irish Nun Eye Study (INES were assessed from digital photographs with a standardized protocol using computer-assisted software. Multivariate regression analyses were used to assess associations with hypertension and CKD, with adjustment for age, body mass index (BMI, refraction, fellow eye RVC, smoking, alcohol consumption, ischemic heart disease (IHD, cerebrovascular accident (CVA, diabetes and medication use.In total, 1122 (91% participants (mean age: 76.3 [range: 56-100] years had gradable retinal images of sufficient quality for blood vessel assessment. Hypertension was significantly associated with a narrower central retinal arteriolar equivalent (CRAE in a fully adjusted analysis (P = 0.002; effect size = -2.16 μm; 95% confidence intervals [CI]: -3.51, -0.81 μm. No significant associations between other retinal vascular parameters and hypertension or between any retinal vascular parameters and CKD were found.Individuals with hypertension have significantly narrower retinal arterioles which may afford an earlier opportunity for tailored prevention and treatment options to optimize the structure and function of the microvasculature, providing additional clinical utility. No significant associations between retinal vascular parameters and CKD were detected.

Arterial hypertension is regarded today as a global public health problem, and the prevalence rate in Portugal is 26.9%. According to the etiology, is classified into primary or secondary arterial hypertension. In about 90% of cases it is not possible to establish a cause, so is called primary arterial hypertension. In the remaining 5 to 10%, it can be identified secondary causes, which are potentially treatable. For secondary arterial hypertension study to be cost-effective, it is essential to understand which patients investigate, and evaluate the best strategy to adopt. The main causes identified as responsible for secondary arterial hypertension are: kidney disease; endocrine and vascular diseases and obstructive sleep apnea. Among these some are consensual, and others more controversial in the literature. In this regard we present two cases of arterial hypertension, which are potentially secondary in etiology, but still focus of debate.

Hepatic angiography: Portal hypertension

International Nuclear Information System (INIS)

Oliver, T.W. Jr.; Sones, P.J. Jr.

1985-01-01

Portal hypertension is usually a manifestation of underlying hepatic parenchymal disease, although it may be secondary to portal or hepatic venous thrombosis and rarely to hyperdynamic portal states. Portal hypertension may present as encephalopathy, ascites, jaundice, hepatic failure, or catastrophic upper gastrointestinal hemorrhage. Radiologic investigation should include indirect or direct measurements of portal pressure, assessment of portal venous perfusion, visualization of collaterals, and demonstration of arterial and venous anatomy for potential shunt procedure. Following survival of initial variceal bleeding, the most effective procedure to prevent recurrent hemorrhage is a shunt to decompress the varices. The decision whether to intervene medically or surgically during the acute hemorrhagic episode as well as the type of shunt used to prevent future hemorrhage is the subject of continuing controversy

Systemic hypertension is an important risk factor for premature cardiovascular disease. Hypertension also contributes to excessive morbidity and mortality. Whereas excellent therapeutic options are available to treat hypertension, there is an unsettled issue about the very definition of hypertension. At what level of blood pressure should we treat hypertension? Does the definition of hypertension change in the presence of co-morbid conditions? This article covers in detail the evolving concepts in the diagnosis and management of hypertension.

Full Text Available Amy Hawkins, Robert TullohDepartment of Congenital Heart Disease, Bristol Royal Hospital for Children, Bristol UKAbstract: Pulmonary hypertension was once thought to be a rare condition and only managed in specialized centers. Now however, with the advent of echocardiography, it is found in many clinical scenarios, in the neonate with chronic lung disease, in the acute setting in the intensive care unit, in connective tissue disease and in cardiology pre- and postoperatively. We have a better understanding of the pathological process and have a range of medication which is starting to be able to palliate this previously fatal condition. This review describes the areas that are known in this condition and those that are less familiar. The basic physiology behind pulmonary hypertension and pulmonary vascular disease is explained. The histopathologic process and the various diagnostic tools are described and are followed by the current and future therapy at our disposal.Keywords: pulmonary hypertension, congenital heart disease, pulmonary vascular resistance, pulmonary vasodilators

Hypertension is one of the major risk factors for cardiovascular diseases that affect a high proportion of people worldwide. Understanding people's levels of knowledge about hypertension might contribute effectively to nurses' efforts to prevent, treat, and control the disease. The objectives of this study were to identify the levels of knowledge about hypertension disease among Jordanian adults and to identify differences in knowledge about hypertension on the basis of sociodemographic and clinical variables. A convenience sample was used in this descriptive comparison design as was the Hypertension Knowledge-Level Scale, which measures 6 dimensions of knowledge about hypertension (definition, treatment, drug compliance, lifestyle, diet, and complications). There were 284 participants, and the mean total knowledge about hypertension was 73.65. The participants had higher levels of knowledge about lifestyle and complications; lower scores were recorded for definition of hypertension as well as the relationship between diet and hypertension. Participants with higher education levels, who watched health programs, exercised regularly, visited their physicians regularly, and had other chronic diseases, had greater knowledge about hypertension. Although the total level of knowledge about hypertension is good among the participants, more efforts are needed to improve all dimensions of hypertension-related knowledge. Sociodemographic and clinical variables have significant relationships with levels of knowledge about hypertension. This necessitates the importance of considering these variables when designing and providing health educational programs.

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

- An explosion of information on pulmonary hypertension has occurred during the past few decades. The perception of this disease has shifted from purely clinical to incorporate new knowledge of the underlying pathology. This transfer has occurred in light of advancements in pathophysiology, histology, and molecular medical diagnostics. - To update readers about the evolving understanding of the etiology and pathogenesis of pulmonary hypertension and to demonstrate how pathology has shaped the current classification. - Information presented at the 5 World Symposia on pulmonary hypertension held since 1973, with the last meeting occurring in 2013, was used in this review. - Pulmonary hypertension represents a heterogeneous group of disorders that are differentiated based on differences in clinical, hemodynamic, and histopathologic features. Early concepts of pulmonary hypertension were largely influenced by pharmacotherapy, hemodynamic function, and clinical presentation of the disease. The initial nomenclature for pulmonary hypertension segregated the clinical classifications from pathologic subtypes. Major restructuring of this disease classification occurred between the first and second symposia, which was the first to unite clinical and pathologic information in the categorization scheme. Additional changes were introduced in subsequent meetings, particularly between the third and fourth World Symposia meetings, when additional pathophysiologic information was gained. Discoveries in molecular diagnostics significantly progressed the understanding of idiopathic pulmonary arterial hypertension. Continued advancements in imaging modalities, mechanistic pathogenicity, and molecular biomarkers will enable physicians to define pulmonary hypertension phenotypes based on the pathobiology and allow for treatment customization.

Pathology of idiopathic non-cirrhotic portal hypertension.

Science.gov (United States)

Guido, Maria; Sarcognato, Samantha; Sacchi, Diana; Colloredo, Guido

2018-04-12

Idiopathic non-cirrhotic portal hypertension is an under-recognized vascular liver disease of unknown etiology, characterized by clinical signs of portal hypertension in the absence of cirrhosis. By definition, any disorder known to cause portal hypertension in the absence of cirrhosis and any cause of chronic liver disease must be excluded to make a diagnosis of idiopathic non-cirrhotic portal hypertension. However, the diagnosis is often difficult because the disease resembles cirrhosis and there is no gold standard test. Liver biopsy is an essential tool: it is able to exclude cirrhosis and other causes of portal hypertension and it allows the identification of the characteristic lesions. Nonetheless, the histological diagnosis of idiopathic non-cirrhotic portal hypertension is not always straightforward, in particular by needle biopsy samples, because there is no pathognomonic lesion, but rather a variety of vascular changes which are unevenly distributed, very subtle, and not all necessarily identified in a single specimen. Pathologists should be able to recognize several patterns of injury, involving portal/periportal areas as well as parenchymal structures.The histological features of idiopathic non-cirrhotic portal hypertension are described in this review, focusing on their interpretation in needle biopsy specimens.

Diagnosis of secondary hypertension: an age-based approach.

Science.gov (United States)

Viera, Anthony J; Neutze, Dana M

2010-12-15

Secondary hypertension is a type of hypertension with an underlying, potentially correctable cause. A secondary etiology may be suggested by symptoms (e.g., flushing and sweating suggestive of pheochromocytoma), examina- tion findings (e.g., a renal bruit suggestive of renal artery stenosis), or laboratory abnormalities (e.g., hypokalemia suggestive of aldosteronism). Secondary hypertension also should be considered in patients with resistant hyper- tension, and early or late onset of hypertension. The prevalence of secondary hypertension and the most common etiologies vary by age group. Approximately 5 to 10 percent of adults with hypertension have a secondary cause. In young adults, particu- larly women, renal artery stenosis caused by fibromuscular dyspla- sia is one of the most common secondary etiologies. Fibromuscular dysplasia can be detected by abdominal magnetic resonance imag- ing or computed tomography. These same imaging modalities can be used to detect atherosclerotic renal artery stenosis, a major cause of secondary hypertension in older adults. In middle-aged adults, aldosteronism is the most common secondary cause of hyperten- sion, and the recommended initial diagnostic test is an aldosterone/ renin ratio. Up to 85 percent of children with hypertension have an identifiable cause, most often renal parenchymal disease. Therefore, all children with confirmed hypertension should have an evaluation for an underlying etiology that includes renal ultrasonography.

2016-12-01

Full Text Available Objectives: Hypertension is a major risk factor for white matter hyperintensities, lacunes, cerebral microbleeds and perivascular spaces, which are MRI markers of cerebral small vessel disease (SVD. Studies have shown associations between these individual MRI markers and cognitive functioning and decline. Recently, a total SVD score was proposed in which the different MRI markers were combined into one measure of SVD, to capture total SVD-related brain damage. We investigated if this SVD score was associated with cognitive decline over 4 years in patients with hypertension. Methods: In this longitudinal cohort study, 130 hypertensive patients (91 patients with uncomplicated hypertension and 39 hypertensive patients with a lacunar stroke were included. They underwent a neuropsychological assessment at baseline and after 4 years. The presence of white matter hyperintensities, lacunes, cerebral microbleeds, and perivascular spaces were rated on baseline MRI. Presence of each individual marker was added to calculate the total SVD score (range 0-4 in each patient. Results: Uncorrected linear regression analyses showed associations between SVD score and decline in overall cognition (p=0.017, executive functioning (p<0.001 and information processing speed (p=0.037, but not with memory (p=0.911. The association between SVD score and decline in overall cognition and executive function remained significant after adjustment for age, sex, education, anxiety and depression score, potential vascular risk factors, patient group and baseline cognitive performance.Conclusions: Our study shows that a total SVD score can predict cognitive decline, specifically in executive function, over 4 years in hypertensive patients. This emphasizes the importance of considering total brain damage due to SVD.

Current scientific evidence addressing the relationship between periodontitis and hypertension is limited to studies producing inconsistent results. All participants of an ongoing representative cohort of Puerto Rican elderly who were ≥70 years old and residing in the San Juan metropolitan area were invited to this cross-sectional study. Periodontal probing depth (PD) and attachment loss (AL) were summarized using the Centers for Disease Control and Prevention and the American Academy of Periodontology definition for severe periodontitis (≥2 teeth with AL ≥6 mm and ≥1 tooth with PD ≥5 mm). Three repeated blood pressure (BP) measurements taken were averaged using a standardized auscultatory method. Information on hypertension history, use of antihypertensive medications, and potential confounders (age, sex, smoking, heavy and binge drinking, diabetes, use of preventive dental services, flossing, body mass index, consumption of fruits, vegetables, whole wheat bread, and high-fiber cereal) was collected during in-person interviews. High BP was defined as average systolic BP ≥140 mm Hg or diastolic ≥90 mm Hg. Multivariate logistic regression models were used to study the relationship between severe periodontitis, hypertension history, and high BP. The study population comprised 182 adults. In multivariate analysis, there was no association between severe periodontitis and hypertension history (odds ratio [OR] = 0.99; 95% confidence interval [CI]: 0.40 to 2.48). Severe periodontitis was associated with high BP, with OR of 2.93 (95% CI: 1.25 to 6.84), after adjusting for age, sex, smoking, and binge drinking. This association was stronger when restricted to those with hypertension or taking antihypertensive medications: OR = 4.20 (95% CI: 1.28 to 13.80). The results of this study suggest that periodontitis may contribute to poor BP control among older adults.

Renovascular Hypertension: Clinical Features, Differential Diagnoses and Basic Principles of Treatment

Directory of Open Access Journals (Sweden)

Petrovic Dejan

2016-09-01

Full Text Available Renovascular hypertension is caused by renal artery stenosis. Its prevalence in populations of hypertensive patients is 1-8%, and in populations of patients with resistant hypertension, it is up to 20%. The two main causes of stenosis are atherosclerosis and fibromuscular dysplasia of the renal artery. The main clinical consequences of renal artery stenosis include renovascular hypertension, ischemic nephropathy and “flash” acute pulmonary oedema. Unilateral stenosis of the renal artery causes angiotensin II-dependent hypertension, and bilateral stenosis of the renal arteries produces volume-dependent hypertension. Renovascular aetiology of hypertension should be questioned in patients with resistant hypertension, hypertension with a murmur identified upon auscultation of the renal arteries, and a noticeable side-to-side difference in kidney size. Non-invasive diagnostic tests include the determination of concentrations of peripheral vein plasma renin activity, the captopril test, captopril scintigraphy, colour Doppler ultrasonography, computed tomography angiography, and nuclear resonance angiography. Renovasography represents the gold standard for the diagnosis of renovascular hypertension. The indications for revascularization of the renal artery include haemodynamically significant renal artery stenosis (with a systolic pressure gradient at the site of stenosis of - ΔP ≥ 20 mmHg, along with the ratio of the pressure in the distal part of the renal artery (Pd and aortic pressure (Pa less than 0.9 (Pd/Pa 0.8, chronic kidney disease (GFR <30 ml/min/1.73 m2 and negative captopril scintigraphy (lack of lateralization.

Insulin resistance is recognized as the pathophysiological hallmark of non-alcoholic fatty liver disease (NAFLD). A relation between insulin sensitivity and left ventricular morphology and function has been reported in essential hypertension, where a high prevalence of NAFLD has been recently found. We investigated the inter-relationship between left ventricular morphology/function, metabolic parameters and NAFLD in 86 never-treated essential hypertensive patients subdivided in two subgroups according to the presence (n = 48) or absence (n = 38) of NAFLD at ultrasonography. The two groups were similar as to sex, age and blood pressure levels. No patient had diabetes mellitus, obesity, hyperlipidemia, or other risk factors for liver disease. Body mass index, waist circumference, triglycerides, glucose, insulin, homeostasis model of assessment index for insulin resistance (HOMA-IR), aspartate aminotransferase and alanine aminotransferase were higher and adiponectin levels were lower in patients with NAFLD than in patients without NAFLD, and were associated with NAFLD at univariate analysis. Patients with NAFLD had similar prevalence of left ventricular hypertrophy compared to patients without NAFLD, but a higher prevalence of diastolic dysfunction (62.5 vs 21.1%, P 220 ms. Diastolic dysfunction (P = 0.040) and HOMA-IR (P = 0.012) remained independently associated with NAFLD at backward multivariate analysis. Non-alcoholic fatty liver disease was associated with insulin resistance and abnormalities of left ventricular diastolic function in a cohort of patients with essential hypertension, suggesting a concomitant increase of metabolic and cardiac risk in this condition.

Pimenta, Eduardo

2012-02-01

Hypertension is an important modifiable risk factor for cardiovascular (CV) morbidity and mortality, and a highly prevalent condition in both men and women. However, the prevalence of hypertension is predicted to increase more among women than men. Combined oral contraceptives (COCs) can induce hypertension in a small group of women and, increase CV risk especially among those with hypertension. Both COC-related increased CV risk and blood pressure (BP) returns to pretreatment levels by 3 months of its discontinuation. The effects of menopause and hormone replacement therapy (HRT) on BP are controversial, and COCs and HRT containing the new generation progestin drospirenone are preferred in women with established hypertension. Despite the high incidence of cancer in women, CV disease remains the major cause of death in women and comparable benefit of antihypertensive treatment have been demonstrated in both women and men.

Pulmonary arterial hypertension associated with congenital heart disease (PAH-CHD) is a complex disease that presents with a broad spectrum of morphological and haemodynamic findings of varying severity. Recently, the aspect of paediatric pulmonary hypertensive vascular disease (PPHVD) has been introduced to expand the understanding of the full spectrum of pulmonary hypertension and increased pulmonary vascular resistance. Evaluation and treatment of PAH-CHD/PPHVD-CHD can be divided into in different topics. First, defining criteria for operability and initiation of advanced therapies preoperatively and postoperatively is an unresolved issue. Second, management of Eisenmenger syndrome is still an important question, with recent evidence on the severity of the disease and a more rapidly progressive course than previously described. Third, the Fontan circulation with no subpulmonary ventricle requires a distinct discussion, definition and classification since even a mild rise in pulmonary vascular resistance may lead to the so-called failing Fontan situation. Patients with CHD and single-ventricle physiology (Fontan/total cavopulmonary anastomosis) require a particularly stepwise and individualised approach. This consensus statement is on the current evidence for the most accurate evaluation and treatment of increased pulmonary artery pressure and resistance, as well as ventricular dysfunction, in children with congenital heart defects, and provides according practical recommendations. To optimise preoperative and postoperative management in patients with PAH-CHD, diagnostic and treatment algorithms are provided. Published by the BMJ Publishing Group Limited.

René García Roche

2016-03-01

Full Text Available Background: aging-associated diseases contribute to morbidity and mortality in the population; therefore, it is necessary to develop intervention strategies to prevent and/or minimize their consequences. Objectives: to evaluate the effectiveness of a cognitive-behavioral intervention aimed at older hypertensive patients treated in primary care in Cardenas and Santiago de Cuba municipalities during 2011-2013. Methods: an intervention study of older adults with hypertension was conducted in two municipalities: Santiago de Cuba and Cárdenas. The intervention group was composed of 399 older patients living in the catchment areas of the Carlos Juan Finlay and Héroes del Moncada polyclinics while the control group included 377 older adults served by the Julian Grimau and Jose Antonio Echeverría polyclinics. The intervention consisted of a systematic strategy to increase knowledge of the disease in order to change lifestyles. Results: in the intervention group, there were more patients with sufficient knowledge of the disease (OR: 1.82, greater control of hypertension (OR: 1.51 and better adherence to treatment (OR: 1.70. By modeling the explanatory variables with hypertension control, being in the intervention group (OR: 0.695 and adhering to treatment (OR: 0.543 were found to be health protective factors. Conclusion: the congnitive-behavioral intervention for older adults treated in primary care of the municipalities studied was effective in improving blood pressure control since it contributed to a greater adherence to treatment.

Development of hypertension in overweight adolescents: a review

Full Text Available Rebecca K Kelly,1 Costan G Magnussen,1,2 Matthew A Sabin,3 Michael Cheung,3 Markus Juonala3–5 1Menzies Institute for Medical Research, University of Tasmania, Hobart, Australia; 2Research Centre of Applied and Preventive Cardiovascular Medicine, University of Turku, Turku, Finland; 3Murdoch Childrens Research Institute, Royal Children's Hospital and University of Melbourne, Parkville, Australia; 4Department of Medicine, University of Turku, 5Division of Medicine, Turku University Hospital, Turku, Finland Abstract: The upward trend in adolescent hypertension is widely attributed to the adolescent obesity epidemic. Secular trends in adolescent prehypertension and hypertension have risen in congruence with increasing trends in the prevalence of overweight and obesity. The correlation between body mass index and blood pressure in adolescence is moderate to strong in most studies and strongest in those classified as overweight or obese. The mechanisms relating to the development of hypertension in overweight adolescents are unclear; however, a number of nonmodifiable and modifiable factors have been implicated. Importantly, certain clinical and biochemical markers in overweight adolescents are indicative of high risk for hypertension, including family history of hypertension and hyperinsulinemia. These characteristics may prove useful in stratifying overweight adolescents as high or low risk of comorbid hypertension. The treatment of overweight and obesity related hypertension in this population focuses on two key modalities: lifestyle change and pharmacotherapy. These approaches focus almost exclusively on weight reduction; however, a number of emerging strategies target hypertension more specifically. Among adolescents with overt hypertension there are also several factors that indicate higher risk of concurrent subclinical disease, persistent adult hypertension, and adult cardiovascular disease. This group may benefit substantially from more

BACKGROUND Sigmoid volvulus (SV) is a life-threatening condition occasionally seen in adults. Adult Hirschsprung's disease (HD)-related SV is rarely complicated by difficult-to-control hypertension. In this report we present the case of an elderly man with a rare constellation of HD, SV, and refractory hypertension. CASE REPORT An 82-year-old man had long-term constipation, moderate abdominal pain, and progressive abdominal distension. A CT scan revealed the typical "coffee bean sign". Blood pressure was abnormal high. Subsequently, the patient's condition deteriorated. Therefore, he underwent a Hartmann's procedure. A giant and redundant sigmoid colon (length more than 60 cm, maximal diameter about 15 cm) was demonstrated to be the cause of SV during the process of surgery. Moreover, abdominal compartment syndrome caused by SV resulted in his high and refractory blood pressure (BP). Postoperative pathological results revealed HD in his sigmoid colon. CONCLUSIONS SV is rarely combined with conditions like refractory hypertension or HD among the elderly. Clinical features of SV typically present with long-term constipation, severe abdominal pain, and progressive abdominal distension. The "coffee bean sign" could be observed in imaging examinations. It is important to note that the management of SV is to relieve the obstruction and prevent recurrence, no matter which therapy is used in elderly patients with Hirschsprung's disease.

During the year 1996-1997, 3275 diabetic patients, registered in Diabetic Clinic of Jinnah Hospital, Lahore, were studied to note the effect of various variables of diabetes mellitus (DM) on hypertension (HTN) and coronary artery diseases (CAD). Out of these 1402 (42.8%) were hypertensive patients. HTN was observed more frequently in obese, older age, longer duration of DM, poor glycemic control and dyslipidemia with p<0.0001. The relative risk (RR) of HTN was significantly increased (p<0.001) in obese (M2.53, F7.77 times), older age (M 3.69,F 9.64 times), longer duration of Dm (2.3 times for both sexes), poor glycemic control (M 2.89, F 4.75 times) and dyslipedemia (M 1.62-5.27, F2.56-9.53 times). While the RR of CAD due to HTN was 4.6 times (M5.4, F4.2 times) (p<0.0001) as compared to normotensive diabetic patients. The risk of developing HTN is more in female diabetics and of CAD in male hypertensive diabetic patients. It is concluded that obesity, older age, poor glycemic control, longer duration of DM and dyslipidemia increases the risk of HTN 2-9.5 times and HTN increases the risk of CAD by 4-5 times, hence requiring aggressive and comprehensive treatment of the diabetes mellitus syndrome.

Systolic hypertension: an increasing clinical challenge in Asia

Science.gov (United States)

Park, Jeong Bae; Kario, Kazuomi; Wang, Ji-Guang

2015-01-01

Systolic hypertension, the predominant form of hypertension in patients aged over 50–60 years, is a growing health issue as the Asian population ages. Elevated systolic blood pressure is mainly caused by arterial stiffening, resulting from age-related vascular changes. Elevated systolic pressure increases the risk of cardiovascular disease, mortality and renal function decline, and this risk may increase at lower systolic pressure levels in Asian than Western subjects. Hence, effective systolic pressure lowering is particularly important in Asians yet blood pressure control remains inadequate despite the availability of numerous antihypertensive medications. Reasons for poor blood pressure control include low awareness of hypertension among health-care professionals and patients, under-treatment, and tolerability problems with antihypertensive drugs. Current antihypertensive treatments also lack effects on the underlying vascular pathology of systolic hypertension, so novel drugs that address the pathophysiology of arterial stiffening are needed for optimal management of systolic hypertension and its cardiovascular complications.

1994-01-01

Pulmonary perfusion imaging with 99m Tc labelled macroaggregated albumin (MAA) was performed in 48 cases of congenital heart diseases of children, including 32 cases with pulmonary hypertension (PH). The change in the total count ratio of the right lung against the left lung between right and left lateral decubitus positions (rt/lt) was used to assess the pulmonary arterial pressure postoperatively. The results showed that rt/lt ratio could qualitatively evaluate the pulmonary arterial pressure. The reproducibility of rt/lt ratio was quite good in experiments with rabbits. Some factors which affected the recovery of PH after operation have been discussed

Grosse, Alexandra; Grosse, Claudia; Lang, Irene M

2017-12-01

The purpose of this study was to discern imaging findings that separate chronic thromboembolic pulmonary hypertension (CTEPH) from other causes of pulmonary hypertension (PH). A total of 143 patients with proven PH (group 1, pulmonary arterial hypertension; group 2, PH due to left heart disease; group 3, PH due to lung disease; group 4, CTEPH; and group 5, PH due to unclear or multifactorial mechanisms) underwent MDCT angiography. The CT images were assessed for the presence of chronic pulmonary embolism (PE), disparity in segmental vessel size, mosaic perfusion, parenchymal densities, bronchial dilatation, and collateral arteries. The frequencies of vascular signs of chronic PE, disparity in segmental vessel size, mosaic perfusion, parenchymal densities, bronchial collateral arteries, and bronchial dilatation were statistically significantly higher in patients with CTEPH than in patients with nonthromboembolic PH. Vascular signs of chronic PE, mosaic perfusion, parenchymal densities, and bronchial dilatation without bronchial wall thickening were significantly more frequent in patients with CTEPH than in patients in groups 1, 2, 3, and 5. There was no significant difference in the frequencies of bronchial collateral arteries between patients with CTEPH and patients in groups 3 and 5. Most patients with CTEPH have direct vascular signs of chronic PE. Secondary signs include disparity in segmental vessel size, mosaic perfusion pattern, parenchymal densities, collateral bronchial arteries, and bronchial dilatation, which help distinguish CTEPH from other causes of PH.

The odds ratio of chronic morbidities was estimated taking smokers as the reference category.ResultsThe odds ratios for (self-reported diabetes, asthma, and hypertension were not significant for smokeless tobacco user compared to smoked tobacco users. The odds ratio of chronic lung diseases (CLDs was significantly lower among smokeless tobacco users compared to smoked tobacco users. The odds ratio of hypertension (measured combined with low education and belonging to lowest wealth quintiles were not significant for smokeless tobacco users compared to smoked tobacco users. Duration of the use of smokeless tobacco and quantity of use was found to have no significant relation with risk of chronic diseases as compared to smoking.ConclusionThis study did not find the significantly higher risk of chronic morbidities except for CLD for smokeless tobacco users compared to smoked tobacco users. The study suggests that the use of any form of tobacco may have a similar risk of chronic diseases.

Rationale: Development and progression of cardiovascular diseases, including hypertension, are often associated with impaired nitric oxide synthase (NOS) function and nitric oxide (NO) deficiency. Current treatment strategies to restore NO bioavailability with organic nitrates are hampered by undesirable side effects and development of tolerance. In this study, we evaluated NO release capability and cardiovascular effects of the newly synthesized organic nitrate 1, 3-bis (hexyloxy) propan-2-y...

Hypertension among HIV-positive populations has emerged as a new threat to the health and well being of people living with HIV, particularly among those receiving antiretroviral therapy. We reviewed the global evidence on the burden of disease (including prevalence and incidence), determinants of hypertension among HIV-positive populations, and the pharmacological management of hypertension in HIV-positive patients. We systematically searched PubMed-MEDLINE and EMBASE from January 2000 through February 2015 for relevant studies and traced their citations through the ISI Web of Science. We also searched the websites of the World Health Organisation, the International Society of Hypertension, and the International AIDS Society and constructed a narrative data synthesis. Hypertension is common in HIV-positive populations, with prevalence estimates ranging from 4.7 to 54.4% in high-income countries, and from 8.7 to 45.9% in low- and middle-income countries. The role of HIV-specific factors including disease severity, duration of disease, and treatments on the presence of hypertension in HIV-positive patients is reported, but patterns remain unclear. The clinical management of hypertension in HIV-positive patients is similar to those with hypertension in the general population; however, additional considerations should be given to potential drug interactions between antihypertensive agents and antiretroviral drugs to inform the clinician's selection of these therapies. Hypertension is common in HIV-positive populations and remains an important comorbidity affecting mortality outcomes. Further research examining the development of hypertension and its associated care in HIV-positive patients is required to optimize management of the dual conditions.

Radiologic evaluation of neonatal and childhood hypertension

The authors reviewed the radiographic findings in 40 neonates and 90 children and adolescents with hypertension. In neonates the common causes of secondary hypertension were renal vascular thrombosis (33%), polycystic kidney disease (25%), and obstructive uropathy (17%). US and renal scans were the most useful studies and yielded diagnostic information in approximately 70% of cases. Surgically correctable hypertension was found in almost half the patients. In patients over 1 year of age, the common causes of hypertension were medical renal disease (50%) and renovascular hypetension (15%). Urography, scintigraphy, and arteriography played a crucial role in their evaluation

Health-related quality of life (HRQOL) is poorly understood in patients with chronic kidney disease (CKD) prior to end-stage renal disease. The association between psychosocial measures and HRQOL has not been fully explored in CKD, especially in African Americans. We performed a cross-sectional analysis of HRQOL and its association with sociodemographic and psychosocial factors in African Americans with hypertensive CKD. There were 639 participants in the African American Study of Kidney Disease and Hypertension Cohort Study. The Short Form-36 was used to measure HRQOL. The Diener Satisfaction with Life Scale measured life satisfaction, the Beck Depression Inventory-II assessed depression, the Coping Skills Inventory-Short Form measured coping, and the Interpersonal Support Evaluation List-16 was used to measure social support. The mean participant age was 60 years at enrollment, and men comprised 61% of participants. Forty-two percent reported a household income less than $15,000/year. Higher levels of social support, coping skills, and life satisfaction were associated with higher HRQOL, whereas unemployment and depression were associated with lower HRQOL (P < 0.05). A significant positive association between higher estimated glomerular filtration rate (eGFR) was observed with the Physical Health Composite (PHC) score (P = 0.004) but not in the Mental Health Composite (MHC) score (P = 0.24). Unemployment was associated with lower HRQOL, and lower eGFR was associated with lower PHC. African Americans with hypertensive CKD with better social support and coping skills had higher HRQOL. This study demonstrates an association between CKD and low HRQOL, and it highlights the need for longitudinal studies to examine this association in the future. Copyright © 2012 Mosby, Inc.

There are high growing prevalence rates of hypertension in South Africa. Consequently, there is a need to assess knowledge and management among hypertensive patients receiving chronic medication from primary health care (PHC) facilities in South Africa as a basis for improving future management. This is important as South Africa seeks to improve its management of chronic diseases. Descriptive, quantitative study amongst chronic hypertensive patients in the chronic disease programme. Patients were interviewed face-to-face by trained pharmacists using a structured questionnaire. Data analysis included descriptive and inferential statistics. Half (53.7%) of the patients had uncontrolled blood pressure (BP). Less than a third of patients (27.7%) knew what hypertension is, the meaning of recorded BP numbers (4.5%), and what normal BP should be (19.9%). All patients who knew the meaning of BP numbers had formal education (p = 0.047). Only 15.6% of the 56.0% patients, who received hypertension information, received it on antihypertensive medicines specifically. The majority of the patients lacked hypertension specific knowledge and only half had controlled BP. Interventions to improve the control of high BP should be targeted at closing knowledge gaps as part of the current chronic treatment initiatives in South Africa to ensure the benefits of increased access to care are realized.

The causes of pulmonary arterial hypertension (PAH) are diverse and include multiple congenital and acquired cardiac diseases as well as diseases primarily affecting the pulmonary vasculature, lung, pleura and chest wall. The traditional role of CT in evaluating PAH includes assessment of pulmonary vasculature and lung parenchyma with limited assessment of the heart. Advances in multidetector CT technology with improved spatial and temporal resolution now permit accurate delineation of cardiac morphology. CT pulmonary angiography (CTPA) is widely utilised in the workup of patients with suspected pulmonary vascular disease and can identify both pulmonary and cardiac causes. As the initial presentation for CTPA is often precipitated by nonspecific, unexplained symptoms and therefore undertaken by a general radiologist, it is important that a systematic approach to the interpretation of these studies, including cardiac evaluation, is routinely adopted. This paper reviews the CT evaluation in pulmonary hypertension with a particular focus on the cardiac causes, their subclassification into congenital systemic to pulmonary shunts and secondary to left heart disease, and their imaging features. It emphasises the use of a systematic approach to interpretation of CTPA examinations both in patients with known PAH and those with previously unsuspected disease. (orig.)

Chinese herbal products (CHPs) have been frequently used among patients with chronic diseases including hypertension; however, the co-prescription pattern of herbal formulae and single herbs remain uncharacterized. Thus, this large-scale pharmacoepidemiological study evaluated the frequency and co-prescription pattern of CHPs for treating hypertension in Taiwan from 2003 to 2009. The database of traditional Chinese medicine (TCM) outpatient claims was obtained from the National Health Insurance in Taiwan. Patients with hypertension during study period were defined according to diagnostic codes in the International Classification of Disease Ninth Revision, Clinical Modification. The frequencies and percentages of herbal formula and single herb prescriptions for hypertension were analyzed. We also applied association rules to evaluate the CHPs co-prescription patterns. The hypertension cohort included 154,083 patients, 123,240 patients of which (approximately 80 %) had used TCM at least once. In total, 81,582 visits involving CHP prescriptions were hypertension related; Tian-Ma-Gou-Teng-Yin and Dan Shen (Radix Salvia Miltiorrhizae) were the most frequently prescribed herbal formula and single herb, respectively, for treating hypertension. This study elucidated the utilization pattern of CHPs for treating hypertension. Future studies on the efficacy and safety of these CHPs and on drug-herb interactions are warranted.

Full Text Available BACKGROUND: People with no previous cardiovascular events or cardiovascular disease represent a primary prevention population. The benefits and harms of treating mild hypertension in primary prevention patients are not known at present. This review examines the existing randomized controlled trial (RCT evidence. OBJECTIVE: Primary objective: To quantify the effects of antihypertensive drug therapy on mortality and morbidity in adults with mild hypertension (systolic blood pressure (BP 140-159 mmHg and/or diastolic BP 90-99 mmHg and without cardiovascular disease. METHODS: Search: We searched CENTRAL (2011, Issue 1, MEDLINE (1948 to May 2011, EMBASE (1980 to May 2011 and reference lists of articles. The Cochrane Database of Systematic Reviews and the Database of Abstracts of Reviews of Effectiveness (DARE were searched for previous reviews and meta-analyses of anti-hypertensive drug treatment compared to placebo or no treatment trials up until the end of 2011. Selection criteria: RCTs of at least 1 year duration. Data collection and analysis: The outcomes assessed were mortality, stroke, coronary heart disease (CHD, total cardiovascular events (CVS, and withdrawals due to adverse effects. MAIN RESULTS: Of 11 RCTs identified 4 were included in this review, with 8,912 participants. Treatment for 4 to 5 years with antihypertensive drugs as compared to placebo did not reduce total mortality (RR 0.85, 95% CI 0.63, 1.15.

Plasma Lipoprotein(a Levels and Atherosclerotic Renal Artery Stenosis in Hypertensive Patients

Directory of Open Access Journals (Sweden)

Cristiana Catena

2015-03-01

Full Text Available Background/Aims: The contribution of emergent cardiovascular risk factors to atherosclerotic renal artery stenosis (ARAS is debated. We investigated the relationship of lipoprotein(a and prothrombotic factors with ARAS in hypertension. Methods: In 50 hypertensive patients with angiographic evidence of ARAS and 58 hypertensive patients who had comparable cardiovascular risk factor burden but no evidence of renovascular disease, we measured renal function, lipoprotein(a, homocysteine, and hemostatic-fibrinolytic markers. Results: Patients with ARAS were more frequently smokers and had longer duration of hypertension, heavier antihypertensive treatment, and worse renal function than controls. Lipoprotein(a was higher in patients with ARAS than controls, whereas no differences were found in homocysteine and all hemostatic variables. Multivariate analysis showed that lipoprotein(a was associated with ARAS independent of other confounders including renal function and history of coronary heart, cerebrovascular, and peripheral artery disease. Conclusion: Lipoprotein(a might contribute to the development of ARAS and detection of elevated levels of this lipoprotein could raise the suspicion of renovascular disease in patients with high blood pressure.

White coat hypertension in definition of metabolic syndrome.

Although white coat hypertension (WCH) is believed to have an effect on health, there is no term defining WCH in metabolic syndrome. Consecutive patients 20 years old or older who underwent a check-up were included. The study included 1068 cases. The prevalences of hyperbetalipoproteinemia, hypertriglyceridemia, dyslipidemia, impaired glucose tolerance (IGT), and WCH were similar to excess weight in that they increased significantly until the seventh decade of life and decreased thereafter significantly (P hypertension (HT), diabetes mellitus (DM), and coronary heart disease (CHD) always increased significantly with age without any decrease (P definition of metabolic syndrome should include reversible metabolic risk factors such as excess weight (overweight and obesity), hyperbetalipoproteinemia, hypertriglyceridemia, dyslipidemia, IGT, and WCH, instead of irrevesible diseases such as DM, HT, CHD, and stroke that have already developed and require drug therapy. After development of one of the final metabolic diseases, the term metabolic syndrome probably loses most of its significance, since from that point on, nonpharmaceutical approaches such as lifestyle changes, diet, and exercise will provide little benefit to prevent development of the others, most likely due to the cumulative effects of the risk factors on body systems over a long period of time.

The growing epidemic of metabolic syndrome has been related to the increased use of fructose by the food industry. In fact, the use of fructose as an ingredient has increased in sweetened beverages, such as sodas and juices. We thus hypothesized that fructose intake by hypertensive rats would have a worse prognosis in developing metabolic disorder and non-alcoholic fatty liver disease. Male Wistar and SHR rats aged 6weeks were given water or fructose (10%) for 6weeks. Blood glucose was measured every two weeks, and insulin and glucose sensitivity tests were assessed at the end of the follow-up. Systolic blood pressure was measure by plethysmography. Lean mass and abdominal fat mass were collected and weighed. Liver tissue was analyzed to determine interstitial fat deposition and fibrosis. Fasting glucose increased in animals that underwent a high fructose intake, independent of blood pressure levels. Also, insulin resistance was observed in normotensive and mostly in hypertensive rats after fructose intake. Fructose intake caused a 2.5-fold increase in triglycerides levels in both groups. Fructose intake did not change lean mass. However, we found that fructose intake significantly increased abdominal fat mass deposition in normotensive but not in hypertensive rats. Nevertheless, chronic fructose intake only increased fat deposition and fibrosis in the liver in hypertensive rats. We demonstrated that, in normotensive and hypertensive rats, fructose intake increased triglycerides and abdominal fat deposition, and caused insulin resistance. However, hypertensive rats that underwent fructose intake also developed interstitial fat deposition and fibrosis in liver. Copyright © 2016 Elsevier Inc. All rights reserved.

Cardiorenal metabolic syndrome in the African diaspora: rationale for including chronic kidney disease in the metabolic syndrome definition.

2009-01-01

Chronic kidney disease (CKD) is more likely to progress to end-stage renal disease (ESRD) in African Americans while the reasons for this are unclear. The metabolic syndrome is a risk factor for the development of diabetes, cardiovascular disease, and has been recently linked to incident CKD. Historically, fewer African Americans meet criteria for the definition of metabolic syndrome, despite having higher rates of cardiovascular mortality than Caucasians. The presence of microalbuminuria portends increased cardiovascular risks and has been shown to cluster with the metabolic syndrome. We recently reported that proteinuria is a predictor of CKD progression in African American hypertensives with metabolic syndrome. In this review we explore the potential value of including CKD markers--microalbuminuria/proteinuria or low glomerular filtration rate (GFR)-in refining the cluster of factors defined as metabolic syndrome, ie, "cardiorenal metabolic syndrome."

Full Text Available Purpose: The association of obesity with hypertension has been recognized for the decades which are the important risk factors for the cardiovascular disease. So the purpose of the present study was to determine association of obesity with hypertension in school going children of Surat. Methodology: School going children aged between 12-18 years, of five schools in Surat were selected for the study. Height and weight were measured and BMI was calculated. Blood pressure measurements were taken as per recommendation of American heart society and family history of hypertension has also been assessed. Hypertension was considered if blood pressure is more than 95th percentile according to the update of task force report and Obesity was diagnosed by BMI for age. Results: Of 682 children, 8.94% were obese and 20.09% were hypertensive. Conclusion: Obesity is strongly associated with hypertension in children and both together may risk factors for later coronary disease.

The burden of chronic diseases is increasing in both low- and middle-income countries. However, healthcare systems in low-income countries are inadequately equipped to deal with the growing disease burden, which requires chronic care for patients. The aim of this study was to assess the capacity of health facilities to manage hypertension in two districts in Uganda. In a cross-sectional study conducted between June and October 2012, we surveyed 126 health facilities (6 hospitals, 4 Health Center IV (HCIV), 23 Health Center III (HCIII), 41 Health Center II (HCII) and 52 private clinics/dispensaries) in Mukono and Buikwe districts in Uganda. We assessed records, conducted structured interviews with heads of facilities, and administered questionnaires to 271 health workers. The study assessed service provision for hypertension, availability of supplies such as medicines, guidelines and equipment, in-service training for hypertension, knowledge of hypertension management, challenges and recommendations. Of the 126 health facilities, 92.9% reported managing (diagnosing/treating) patients with hypertension, and most (80.2%) were run by non-medical doctors or non-physician health workers (NPHW). Less than half (46%) of the facilities had guidelines for managing hypertension. A 10th of the facilities lacked functioning blood pressure devices and 28% did not have stethoscopes. No facilities ever calibrated their BP devices except one. About a half of the facilities had anti-hypertensive medicines in stock; mainly thiazide diuretics (46%), beta blockers (56%) and calcium channel blockers (48.4%). Alpha blockers, mixed alpha & beta blockers and angiotensin II receptor antagonists were only stocked by private clinics/dispensaries. Most HCIIs lacked anti-hypertensive medicines, including the first line thiazide diuretics. Significant knowledge gaps in classification of patients as hypertensive were noted among respondents. All health workers (except 5, 1.9%) indicated that they

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

The aim of this study was to interpret how hypertensive patients experience health care self-management. Hypertension is one of the most prevalent chronic diseases worldwide. The involvement of individuals in the management of their health care to treat this disease is fundamental, with aid and advice from healthcare professionals, especially nurses, so that hypertensive patients can effectively self-manage their health care. Qualitative study. Hypertensive patients were recruited using theoretical sampling. The study sample consisted of 28 hypertensive patients aged 18-59 years who were registered in the e-Health programme of the Ministry of Health. Data were collected and analyzed between September 2012-October 2014 using a semi-structured interview based on the methodological framework of the constructivist grounded theory. The participants' statements depicted an outline of their experience with the disease: the beginning of the illness; understanding the disease process; incorporating behaviour for self-management of the disease; experiencing attitudes and actions in the control and treatment of the disease; and being treated in the public healthcare system. A central phenomenon emerged, namely hypertensive patients' experience of self-management of health care. This phenomenon has paths, actions and interactions. When patients discover that they have the disease and become aware of the disease process, they assume the identity of being hypertensive and become proactive in their health care and in living with their families and in communities. © 2016 John Wiley & Sons Ltd.

Hypertension covers a large portion of burden of diseases, especially in the developing countries. The unequal distribution of hypertension in the population may affect 'health for all' goal. This study aimed to investigate the socioeconomic inequality of hypertension in Iran and to identify its influencing factors. We used data from Iran's surveillance system for risk factors of noncommunicable diseases which was conducted on 89 400 individuals aged 15-64 years in 2005. To determine the socioeconomic status of participants, a new variable was created using a principal component analysis. We examined hypertension at different levels of this new variable and calculated slop index of inequality (SII) and concentration index (C) for hypertension. We then applied Oaxaca-Blinder decomposition analysis to determine the causes of inequality. The SII and C for hypertension were -32.3 and -0.170, respectively. The concentration indices varied widely between different provinces in Iran and was lower (more unequal) in women than in men. There was significant socioeconomic inequality in hypertension. The results of decomposition indicated that 40.5% of the low-socioeconomic group (n = 18190) and 16.4% of the high-socioeconomic group (n = 16335) had hypertension. Age, education level, sex and residency location were the main associated factors of the difference among groups. According to our results, there was an inequality in hypertension in Iran, so that individuals with low socioeconomic status had a higher prevalence of hypertension. Age was the most contributed factor in this inequality and women in low-socioeconomic group were the most vulnerable people for hypertension.

In addition, it is oneof the major risk factor for cardiovascular and cerebrovascular diseases.Hypertension, considered a “silent murder”, is the largest social problem indeveloped countries and in a large number of developing countries. Despite of knownefficacy and affectivity of various preventive and control measures, including thepharmacological ones, hypertension will continue, for decades, representing oneof the largest health challenges and high cost disease for individuals and society. Ifcontrol of existed cases, as well as control and prevention of risks factors for thisdisease are not implemented, this problematic will affect a large proportion of thepopulation in our country, which, in 2020, will have had increase significantly over60 years of age.Hypertension is a multifactor, multisystem syndrome. It can be cause bymultiple causes, being related to inadequate life style, constitutional factors, suchas: sex, age, race/color and family history; as well as environmental issues, suchas: sedentary lifestyle, stress, smoking, alcoholism, inadequate diet and obesity.Due to its silent course, a person can be surprised by its complications, beingnecessary learn to live with its chronic nature on an every day basis. Nevertheless,this type of problem is influenced by a series of determinants, including personalitycharacteristics, forms to face the disease, self-concept, self-image, experience withthe disease and health care professionals attitudes.One of the difficulties found in the treatment of persons with hypertensionis the lack of adhesion to the treatment, as 50% of the known patients withhypertension don’t treat themselves, and among those who do, few have controlledblood pressure. Between 30 and 50% of persons with hypertension stop treatmentwithin the first year of treatment, and 75% after five

Full Text Available Kuwait is a small country located on the northeastern part of the Arabian Peninsula. The most recent data on hypertension show: (a a prevalence rate of 26.3%, (b awareness of the disorder in only 23% of affected persons, (c mild to moderate hypertension in 86% of subjects, (d increased proportion of hypertensive patients at older age, (e high prevalence in diabetics at age > 35 years and (f high association with obesity. Most patients still use beta-blockers with a recent surge in calcium channel-blockers (except for immediate-release nifedipine and angiotensin converting enzyme inhibitors. Hypertension was responsible for 935 hospital admissions in 1997. Its related co-morbid conditions such as ischemic heart disease, cerebrovascular accidents, congestive heart failure and chronic renal failure were responsible for 4111, 791, 690 and 978, hospital admissions, respectively, during the same year. Hypertension is the fourth common cause of end-stage renal disease. The most disturbing observation is the lack of disease awareness and the persistently high mortality rate of the disease and its co-morbid conditions. Efforts should be directed towards increase of awareness of this important risk factor for cardiovascular disease.

Uric acid (UA) is associated with high blood pressure in adolescents and with left ventricular hypertrophy (LVH) and cardiovascular disease (CVD) in adults. We sought to determine if UA is independently associated with CVD risk factors and left ventricular mass (LVM) over time in hypertensive youth. This was a 1-year prospective observational study of hypertensive children aged 3-19 years. Cross-sectional and longitudinal associations of serum UA with CVD risk factors and LVM were explored. Of the 49 children who completed both the baseline and 12-month assessments, at baseline the mean age was 13.8 years and mean UA was 5.5 mg/dL; 24% had elevated UA, 51% were overweight/obese and 39% had LVH. Measures of adiposity, low high-density lipoprotein cholesterol, high-sensitivity C-reactive protein, LVM and LVH were all significantly associated with elevated UA at baseline, but not with change over time. Each 1 mg/dL increase in baseline UA was associated with a 2.5 g/m(2.7) increase in the LVM index at follow-up (95% confidence interval 0.64, 4.39; p = 0.01); after adjustment for age, sex, race, body mass index z-score, change in UA, time, blood pressure and medication use, this association was no longer significant. Hypertensive children with elevated UA have a higher prevalence of obesity-related CVD risk factors. Among hypertensive children, UA may be a marker of adiposity and not an independent CVD risk factor.

Co-segregation of Norrie disease and idiopathic pulmonary hypertension in a family with a microdeletion of the NDP region at Xp11.3-p11.4.

Staropoli, John F; Xin, Winnie; Sims, Katherine B

Norrie disease is a rare X-linked congenital retinal vasculopathy that may be accompanied by sensorineural deafness, mental retardation, and other neurological deficits. Here we present a family in which Norrie disease co-segregated with either early-onset idiopathic pulmonary hypertension or sudden death preceded by a period of progressive dyspnea. Neither Norrie disease, nor its atypical variants described to date, have been associated with this extended clinical phenotype. Molecular analysis of the Norrie disease gene (NDP) and adjacent loci was performed by multiplex ligation-dependent probe amplification and comparative genomic hybridisation. Affected males in this family showed an inherited hemizygous deletion restricted to NDP and two immediately telomeric genes, monoamine oxidase-B (MAO-B) and monoamine oxidase-A (MAO-A), which encode closely related enzymes that metabolize biogenic amines including serotonin, dopamine, and norepinephrine. Sequencing of the deletion junction showed an unusual pattern in which a region of microhomology flanked intervening genomic sequence. Because abnormalities of biogenic amines, particularly serotonin, have been implicated in the pathophysiology of pulmonary hypertension, we propose that presumed MAO deficiency in these patients may represent a novel risk factor for pulmonary hypertension, particularly forms with very early onset. Fine-mapping of other microdeletions at this locus may provide insights into additional mechanisms for nonrecurrent genomic rearrangements at this and other chromosomal loci.

Zhong, Ming; Kim, Luke K; Swaminathan, Rajesh V; Feldman, Dmitriy N

2017-07-01

Sympathetic overactivation of renal afferent and efferent nerves have been implicated in the development and maintenance of several cardiovascular disease states, including resistant hypertension and heart failure with both reduced and preserved systolic function. With the development of minimally invasive catheter-based techniques, percutaneous renal denervation has become a safe and effective method of attenuating sympathetic overactivation. Percutaneous renal denervation, therefore, has the potential to modify and treat hypertension and congestive heart failure. Although future randomized controlled studies are needed to definitively prove its efficacy, renal denervation has the potential to change the way we view and treat cardiovascular disease.

The present review examines the types of hypertension that women may suffer throughout life, their physiopathological characteristics and management. In early life, the currently used low-dose oral contraceptives seldom cause hypertension. Pregnancy provokes preeclampsia, its main medical complication, secondary to inadequate transformation of the spiral arteries and the subsequent multisystem endothelial damage caused by deportation of placental factors and microparticles. Hypertension in preeclampsia is an epiphenomenon which needs to be controlled at levels that reduce maternal risk without impairing placental perfusion. The hemodynamic changes of pregnancy may unmask a hypertensive phenotype, may exacerbate a chronic hypertension, or may complicate hypertension secondary to lupus, renovascular lesions, and pheochromocytoma. On the other hand a primary aldosteronism may benefit from the effect of progesterone and present as a postpartum hypertension. A hypertensive pregnancy, especially preeclampsia, represents a risk for cardiac, vascular and renal disease in later life. Menopause may mimic a pheochromocytoma, and is associated to endothelial dysfunction and salt-sensitivity. Among women, non-pharmacological treatment should be forcefully advocated, except for sodium restriction during pregnancy. The blockade of the renin-angiotensin system should be avoided in women at risk of pregnancy; betablockers could be used with precautions during pregnancy; diuretics, ACE inhibitors and angiotensin receptor antagonists should not be used during breast feeding. Collateral effects of antihypertensives, such as hyponatremia, cough and edema are more common in women. Thus, hypertension in women should be managed according to the different life stages.

Pulmonary arterial hypertension associated with congenital heart disease

Directory of Open Access Journals (Sweden)

Michele D'Alto

2012-12-01

Full Text Available Pulmonary arterial hypertension (PAH is a common complication of congenital heart disease (CHD, with most cases occurring in patients with congenital cardiac shunts. In patients with an uncorrected left-to-right shunt, increased pulmonary pressure leads to vascular remodelling and dysfunction, resulting in a progressive rise in pulmonary vascular resistance and increased pressures in the right heart. Eventually, reversal of the shunt may arise, with the development of Eisenmenger's syndrome, the most advanced form of PAH-CHD. The prevalence of PAH-CHD has fallen in developed countries over recent years and the number of patients surviving into adulthood has increased markedly. Today, the majority of PAH-CHD patients seen in clinical practice are adults, and many of these individuals have complex disease or received a late diagnosis of their defect. While there have been advances in the management and therapy in recent years, PAH-CHD is a heterogeneous condition and some subgroups, such as those with Down's syndrome, present particular challenges. This article gives an overview of the demographics, pathophysiology and treatment of PAH-CHD and focuses on individuals with Down's syndrome as an important and challenging patient group.

Tobacco smoking in any form is a major risk factor for coronary artery disease (CAD), hypertension (HTN), chronic obstructive pulmonary disease (COPD), oral, nasopharyngeal, bronchial and other visceral malignancies. Cessation of smoking exerts considerable beneficial effect on development, recurrence and prognosis of these diseases. Present communication is based on the study of nine cases who had concurrent CAD, HTN, COPD and mitotic and/or pre malignant lesions due to unabated smoking. The youngest patient was a 35-year-old male having a smoking index of 300, presenting with acute coronary syndrome, COPD, HTN and buccal leukoplakia. Associated genitourinary malignancies in two cases and osteosarcoma in one case was an unusual presentation. These cases highlight the prognosis and public health implications of continuous smoking.

Chronic Kidney Disease (CKD) is associated with a high risk of developing further severe complications such as, cardiovascular disease and eventually End Stage Renal Disease (ESRD) leading to death. Hypertension plays a key role in the progression of renal failure and is also a chief risk factor for the occurrence of End Stage Renal Disease (ESRD). This study investigates the possible association of insertion (I) and deletion (D) polymorphism of ACE gene in patients of Chronic Kidney Disease (CKD) with and without hypertension (HT). Total 120 participants with 30 members in each group (Control, HT, CKD and CKD-HT) were chosen followed by informed consent. Blood samples were collected and subjected to biochemical analyses and nested PCR amplification was performed to genotype the DNA, for ACE I/D using specific primers. Statistical analyses were performed using SPSS version 13. Allele and genotypic frequency was calculated by direct gene counting method. Comparison of the different genotypes was done by using Chi square test. Odd's ratios were calculated with a 95% confidence interval limit. The ACE genotype were distributed as II, 27 (90%); DD, 2 (6.67%) and ID, 1 (3.33%) in control, II, 1 (3.33%); DD, 5 (16.67%) and ID, 24 (80%) in HT, II, 4 (13.33%); DD, 24 (80%) and ID, 2 (6.67%) in CKD and II, 0 (0%); DD, 2 (6.67%) and ID, 28 (93.33%) in CKD-HT group. D allele of ACE gene confers a greater role in genetic variations underlying CKD and hypertension. This result suggest that CKD patients should be offered analysis for defects in ACE I/D polymorphisms, especially if they are hypertensive.

Congenital absence of the portal vein (CAPV) is a rare malformation in which intestinal and splenic venous flow bypasses the liver and drains directly into the systemic circulation via a congenital portosystemic shunt. We describe two cases of CAPV presenting as pulmonary hypertension that were initially suspected as primary pulmonary hypertension. However, subsequent ultrasonography and CT detected the absence of a portal vein and the presence of a portosystemic shunt. Pulmonary hypertension is a recognized complication of liver disease and portal hypertension. However, these two cases illustrate that CAPV may result in pulmonary hypertension without liver disease or portal hypertension

Pulmonary hypertension occurs as the result of disease processes increasing pressure within the pulmonary circulation, eventually leading to right ventricular failure. Patients may become critically ill from complications of pulmonary hypertension and right ventricular failure or may develop pulmonary hypertension as the result of critical illness. Diagnostic testing should evaluate for common causes such as left heart failure, hypoxemic lung disease and pulmonary embolism. Relatively few patients with pulmonary hypertension encountered in clinical practice require specific pharmacologic treatment of pulmonary hypertension targeting the pulmonary vasculature. Management of right ventricular failure involves optimization of preload, maintenance of systemic blood pressure and augmentation of inotropy to restore systemic perfusion. Selected patients may require pharmacologic therapy to reduce right ventricular afterload by directly targeting the pulmonary vasculature, but only after excluding elevated left heart filling pressures and confirming increased pulmonary vascular resistance. Critically-ill patients with pulmonary hypertension remain at high risk of adverse outcomes, requiring a diligent and thoughtful approach to diagnosis and treatment. © The Author(s) 2015.

Full Text Available Background/Aim. World Health Organization (WHO studies on the global level have shown that one of the major problems of the public health is hypertension. Blood pressure level greater than 140/90 mmHg is directly and predictively linked to other cardiovascular diseases. The aim of this research was to determine the prevalence of hypertension and the risk groups among the adult population in the Šumadija District, Serbia. Methods. This cross-sectional study included 1.669 elderly population of the Šumadija District, aged 25-74. The study was performed according to the protocol of the Country Wide Integrated Noncommunicable Disease Intervention (CINDI international program. Results. In the Šumadija District more than a half of the population aged 25-74 suffers from hypertension (53%. In the Šumadija District 9% of population has undiagnosed hypertension. In the group of people familiar with their high blood pressure problems, good disease control is achieved in only 46% of them. Statistically, hypertension occurs more frequently in males aged 45-74, of lower education, and in rural population. This is the target group for implementation of the high risk strategy. Statistically, there is a higher prevalence of hypertension in people suffering from myocardial infarction (p = 0.04, angina pectoris (p = 0.00, other cardiac diseases (cardiac insufficiency (p = 0.00 and cerebrovascular crises (p = 0.04. Conclusion. A continuous increase of patients with hypertension, coupled with the developed complications and increase in cardiovascular diseases as a cause of death, points to the lack of effective access to prevention and early detection of these diseases in the primary health care among the risk groups in Šumadija.

Full Text Available Background: Mixed connective tissue disease (MCTD has features common to lupus, scleroderma and myositis with high levels of antibodies to U1 ribonucleoprotein (U1 RNP. Identification of a high incidence of pulmonary artery hypertension (PAH has changed its prospect. We report the largest series from India. Settings and Design: Rheumatology unit of a tertiary care centre in India; prospective. Materials and Methods: Patients seen between January 2002 and June 2004, satisfying the Kasukawa criteria were enrolled. All patients had a complete laboratory work-up including pulmonary function test, 2-D echocardiography, and Schirmer′s test, antinuclear antibodies (ANA and antibodies to extractable nuclear antigens. HRCT of chest was done where indicated. All patients were given standard treatment and followed up regularly. Results: Out of 1500 patients, thirteen (one male were diagnosed to have MCTD. The median follow-up period was 18 months [Interquartile range (IQR 12-22]. The median age of onset of symptoms was 36 years (IQR 22-39 and the median duration of disease was three years (IQR 1.75-4. The most common manifestation was polyarthritis followed by puffy fingers. Sjogren′s syndrome, dysphagia and interstitial lung disease, was present in four, three and two patients respectively. Two patients each had myositis and migraine. None had PAH, serositis or renal involvement. Arthritis, puffy fingers and RaynaudÆs phenomenon were the most common manifestations at onset. All patients were positive for ANA and anti U1 RNP. Two patients each had antibodies to Sm and SSA. Response to treatment also was noted. Conclusion: Pulmonary artery hypertension is not common in early MCTD.

We estimated hypertension and diabetes prevalence among US homeless adults compared with the general population, and investigated prevalence trends. We systematically searched 5 databases for published studies (1980–2014) that included hypertension or diabetes prevalence for US homeless adults, pooled disease prevalence, and explored heterogeneity sources. We used the National Health Interview Survey for comparison. We included data from 97 366 homeless adults. The pooled prevalence of self-reported hypertension was 27.0% (95% confidence interval = 23.8%, 29.9%; n = 43 studies) and of diabetes was 8.0% (95% confidence interval = 6.8%, 9.2%; n = 39 studies). We found no difference in hypertension or diabetes prevalence between the homeless and general population. Additional health care and housing resources are needed to meet the significant, growing burden of chronic disease in the homeless population. PMID:25521899

Hypertension is the most common non-communicable disease and risk factor for heart failure, stroke, chronic kidney disease and ischemic heart disease in sub-Saharan Africa. Few population-based studies have been conducted recently in Nigeria and, in Abia State, no previous study has been conducted on the prevalence and correlates of hypertension among the populace. The purpose of our study was, therefore, to determine the prevalence and determinants of high blood pressure in Abia State, southeastern Nigeria. We hypothesise that high blood pressure burden is high in Abia State. The study was a community based cross-sectional house-to-house survey aimed at ascertaining the burden/prevalence of hypertension in the state as well as identifying related risk factors associated with them. The study was conducted in rural and urban communities in Abia State, Nigeria. Participants in the study were men and women aged > or =15 years and were recruited from the three senatorial zones in the state. A total of 2,999 respondents were selected for the survey and, 2,983 consented to be interviewed giving a response rate of 99.5%. The data for 2,928 participants were suitable for analysis. Of these, 1,399 (47.8%) were men. The mean age of the population was 41.7 +/- 18.5 years (range 18-96 years). About 54% of the population were < or =40 years. Ninety percent had at least primary education with about 47% having completed secondary education. Expectedly, 96% of the respondents were Ibos, the predominant tribe in the southeastern part of the country. Women had significantly higher BMI than the men. Similarly, waist circumference was also larger in women but waist-to-hip ratio was only significantly higher in women in the urban areas compared to those in rural areas. Thirty-one percent of all participants had systolic hypertension (33.5% in men and 30.5% in women). This sex difference was statistically different in the urban area. On the other hand, diastolic hypertension was 22

Seedat, Y K

2007-01-01

Sub-Saharan Africa (SSA) has huge amounts of natural resources and a source of strategic minerals. It is not overpopulated compared to the Asian continent, yet the economic conditions have deteriorated alarmingly in recent years. It is the poorest continent and has the lowest per capita income in the world. An analysis of the causes of poverty and its impact on health, particularly cardiovascular diseases (CVD) and hypertension, was carried out and is reported on here. A 'second-wave epidemic' is currently sweeping through SSA, other developing countries and Eastern Europe, making a comprehensive CVD programme necessary. Social, economic and cultural factors impair the control of hypertension, diabetes, obesity, tobacco use and other risk factors for CVD in SSA. Primary prevention through a population-based, lifestyle-linked programme, as well as cost-effective methods for detection and management are synergistically linked. The existing healthcare infrastructure needs to be orientated to meet the challenge of CVD, while empowering the community through health education.

Graves' disease, a well-known cause of hyperthyroidism, is an autoimmune disease with multi-system involvement. More prevalent among young women, it appears as an uncommon cardiovascular complication during pregnancy, posing a diagnostic challenge, largely owing to difficulty in detecting the complication, as a result of a low index of suspicion of Graves' disease presenting during pregnancy. Globally, cardiovascular disease is an important factor for pregnancy-related morbidity and mortality. Here, we report a case of Graves' disease detected for the first time in pregnancy, in a patient presenting with bi- ventricular heart failure, severe pulmonary hypertension and pre- eclampsia. Emphasis is placed on the spectrum of clinical presentations of Graves' disease, and the importance of considering this thyroid disorder as a possible aetiological factor for such a presentation in pregnancy. A 30-year-old Bangladeshi-Bengali woman, in her 28th week of pregnancy presented with severe systemic hypertension, bi-ventricular heart failure and severe pulmonary hypertension with a moderately enlarged thyroid gland. She improved following the administration of high dose intravenous diuretics, and delivered a premature female baby of low birth weight per vaginally, twenty four hours later. Pre-eclampsia was diagnosed on the basis of hypertension first detected in the third trimester, 3+ oedema and mild proteinuria. Electrocardiography revealed sinus tachycardia with incomplete right bundle branch block and echocardiography showed severe pulmonary hypertension with an estimated pulmonary arterial systolic pressure of 73 mm Hg, septal and anterior wall hypokinesia with an ejection fraction of 51%, grade I mitral and tricuspid regurgitation. Thyroid function tests revealed a biochemically hyperthyroid state and positive anti- thyroid peroxidase antibodies was found.

Oxidative stress seems to play an important role in the pathophysiology of essential hypertension. We aimed to examine serum MDA, NO, 8-OHdG, ADMA, NT, CoQ10 and TAC as biomarkers of oxidative stress in dipper and non-dipper hypertensive patients. Eighteen dipper hypertensives, 20 non-dipper hypertensives and 22 healthy control subjects were included in the study. Clinical assessment and ambulatory blood pressure monitoring were performed in patients. Serum MDA, TAC and NO levels were measured by using spectrophotometric methods. CoQ10 levels were measured by HPLC method. 8-OHdG, ADMA and NT were quantitated by ELISA methods. MDA levels were significantly higher in dipper and non-dipper groups compared to controls (pstres compared with dipper hypertensive patients, which plays an important role in the development of cardiovascular diseases. Increased MDA and reduced TAC levels might be considered as prospective prognostic markers of the development of cardiovascular diseases in dipper and non-dipper hypertensive patients.

Low- and middle-income countries account for the majority of hypertension disease burden. However, little is known about the distribution of this illness within subpopulations of these countries, particularly among those who live in urban informal settlements. A cross-sectional hypertension survey was conducted in 2003 among 5649 adult residents of a slum settlement in the city of Salvador, Brazil. Hypertension was defined as either an elevated arterial systolic (≥140 mmHg) or diastolic (≥90 mmHg) blood pressure. Sex-specific multivariable models of systolic blood pressure were constructed to identify factors associated with elevated blood pressure. The prevalence of hypertension in the population 18 years and older was 21% (1162/5649). Men had 1.2 times the risk of hypertension compared with women (95% confidence intervals (CI), 1.05, 1.36). Increasing age and lack of any schooling, particularly for women, were also significantly associated with elevated blood pressure (p slum community was lower than reported frequencies in the non-slum population of Brazil and Salvador, yet both disease awareness and treatment frequency were low. Further research on hypertension and other chronic non-communicable diseases in slum populations is urgently needed to guide prevention and treatment efforts in this growing population.

A small proportion of the treated hypertensive population consistently has a blood pressure greater than 140/90 mm Hg despite a triple therapy including a diuretic, a calcium channel blocker, and a blocker of the renin-angiotensin system. According to guidelines, these patients have so-called resistant hypertension. The prevalence of this clinical condition is higher in tertiary than primary care centers and often is associated with chronic kidney disease, diabetes, obesity, and sleep apnea syndrome. Exclusion of pseudoresistant hypertension using ambulatory or home blood pressure monitoring is a crucial step in the investigation of patients with resistant hypertension. Thus, among the multiple factors to consider when investigating patients with resistant hypertension, ambulatory blood pressure monitoring should be performed very early. Among other factors to consider, physicians should investigate patient adherence to therapy, assess the adequacy of treatment, exclude interfering factors, and, finally, look for secondary forms of hypertension. Poor adherence to therapy accounts for 30% to 50% of cases of resistance to therapy depending on the methodology used to diagnose adherence problems. This review discusses the clinical factors implicated in the pathogenesis of resistant hypertension with a particular emphasis on pseudoresistance, drug adherence, and the use of ambulatory blood pressure monitoring for the diagnosis and management of resistant hypertension.

The significance of white-coat hypertension in older persons with isolated systolic hypertension remains poorly understood. We analyzed subjects from the population-based 11-country International Database on Ambulatory Blood Pressure Monitoring in Relation to Cardiovascular Outcomes database who had daytime ambulatory blood pressure (BP; ABP) and conventional BP (CBP) measurements. After excluding persons with diastolic hypertension by CBP (≥90 mm Hg) or by daytime ABP (≥85 mm Hg), a history of cardiovascular disease, and persons hypertension. During a median follow-up of 10.6 years, there was a total of 655 fatal and nonfatal cardiovascular events. The analyses were stratified by treatment status. In untreated subjects, those with white-coat hypertension (CBP ≥140/hypertension, the cardiovascular risk was similar in elevated conventional and normal daytime systolic BP as compared with those with normal conventional and normal daytime BPs (adjusted hazard rate: 1.10 [95% CI: 0.79–1.53]; P=0.57). However, both treated isolated systolic hypertension subjects with white-coat hypertension (adjusted hazard rate: 2.00; [95% CI: 1.43–2.79]; Phypertension who have their ABP normalized on antihypertensive therapy but with residual white-coat effect by CBP measurement have an entity that we have termed, “treated normalized hypertension.” Therefore, one should be cautious in applying the term “white-coat hypertension” to persons receiving antihypertensive treatment.

Vascular Remodeling in Experimental Hypertension

Full Text Available The basic hemodynamic abnormality in hypertension is an increased peripheral resistance that is due mainly to a decreased vascular lumen derived from structural changes in the small arteries wall, named (as a whole vascular remodeling. The vascular wall is an active, flexible, and integrated organ made up of cellular (endothelial cells, smooth muscle cells, adventitia cells, and fibroblasts and noncellular (extracellular matrix components, which in a dynamic way change shape or number, or reorganize in response to physiological and pathological stimuli, maintaining the integrity of the vessel wall in physiological conditions or participating in the vascular changes in cardiovascular diseases such as hypertension. Research focused on new signaling pathways and molecules that can participate in the mechanisms of vascular remodeling has provided evidence showing that vascular structure is not only affected by blood pressure, but also by mechanisms that are independent of the increased pressure. This review will provide an overview of the evidence, explaining some of the pathophysiologic mechanisms participating in the development of the vascular remodeling, in experimental models of hypertension, with special reference to the findings in spontaneously hypertensive rats as a model of essential hypertension, and in fructose-fed rats as a model of secondary hypertension, in the context of the metabolic syndrome. The understanding of the mechanisms producing the vascular alterations will allow the development of novel pharmacological tools for vascular protection in hypertensive disease.
