OBJECTIVE To analyze the frequency of self-reported systemic arterial hypertension and associated factors. METHODS Study based on data provided by the system of Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (VIGITEL--Telephone-based surveillance of risk and protective factors for chronic diseases), collected in 2006 in Brazil's capitals and Federal D...

Objective: Intracerebral hemorrhage (ICH) following systemic and chronic hypertension is one of the main causes of acute stroke leading to disability and death. Identifying the risk factors in ICH patients can be effective in reducing bleeding and the rates of mortality and disability in these patients. This study was carried out to investigate the factors associated with ICH.Methods: A t...

Background: Elevation in PA pressures has been observed by 2D echo in some but not all hypertensive patients. The mechanism and hemodynamic impact of pulmonary hypertension in these patients remains unclear. Methods: We reviewed echoes of all patients referred with systemic hypertension between 9/2006 to 5/2009 to identify those patients with left ventricular hypertrophy, normal systolic functi...

Integration of omics with clinical data through machine learning is the future personalised and precision medicine in systemic sclerosis-associated pulmonary arterial hypertensionhttps://bit.ly/3jsyBoV

Primary systemic hypertension affects 10%-25% of individuals presenting for surgery and anaesthesia and constitutes an important cause of cancellation of elective surgeries. Much of the fear stems from the fact that hypertension may lead to adverse perioperative outcomes. Although long-standing hypertension increases the risk of stroke, renal dysfunction or major adverse cardiovascular events, ...

The hyperactivity of the brain renin-angiotensin system (RAS) has been implicated in the development and maintenance of hypertension in several types of experimental and genetic hypertension animal models. We previously reported that in the murine brain, aminopeptidase A (APA) is involved in the conversion of angiotensin II (AngII) to AngIII and that AngIII is one of the main effector peptides ...

The haemodynamic effects of nifedipine were studied in 14 patients (aged 8-14 years, seven male and seven female) with ventricular septal defect with and without pulmonary hypertension. All underwent left and right heart catheterisation. In each patient the pressures and heart rate were measured and blood samples were taken for oximetry before and after sublingual administration of 10 mg nifedi...

Coronary hemodynamics are known to be affected by intravascular and extravascular factors that vary regionally and transmurally between the perfusion territories of left and right coronary arteries. However, despite clinical evidence that left coronary arterial dominance portends greater cardiovascular risk, relatively little is known about the effects of left or right dominance on regional con...

An increased renal resistive index (RI) and albuminuria are markers of target organ damage secondary to systemic hypertension. This study evaluated associations between systemic blood pressure (SBP), renal RI, pulsatility index (PI), and albuminuria in dogs with pituitary-dependent hyperadrenocorticism (PDH). Predictors of overall mortality were investigated. Twenty client-owned dogs with PDH a...

objectives in this study, besides studying the rv function in ssc patients, attempts have been made to find a new possible noninvasive echocardiographic test for early diagnosis of systolic failure as a pah complication. methods 30 patients with at least a 2-year history of diffuse ssc confirmed by an expert rheumatologist were enrolled in this study. all the patients underwent transthoracic ec...
