A routine electrocardiogram cannot be used to determine the size of myocardial infarction in the rat
(Associação Brasileira de Divulgação Científica, 2005-04-01)
Nine lead electrocardiograms of non-infarcted (N = 61) and infarcted (N = 71) female Wistar rats (200-250 g) were analyzed in order to distinguish left ventricle myocardial infarction (MI) larger than 40% (LMI) from MI ...
GROWTH HORMONE ATTENUATES MYOCARDIAL FIBROSIS IN RATS WITH CHRONIC PRESSURE OVERLOAD-INDUCED LEFT VENTRICULAR HYPERTROPHY
(Wiley-Blackwell Publishing, Inc, 2009-03-01)
1. The role of growth hormone (GH) in cardiac remodelling and function in chronic and persistent pressure overload-induced left ventricular hypertrophy has not been defined. The aim of the present study was to assess ...
Cardiovascular changes in patients with non-severe Plasmodium vivax malaria
(2016-06-01)
Background: Cardiovascular system involvement in patients with Plasmodium vivax malaria has been poorly addressed. The aim of this study was to evaluate cardiac structures and function, and serum markers of cardiovascular ...
Diastolic function and functional capacity after a single session of continuous positive airway pressure in patients with compensated heart failure
(Universidade de São Paulo (USP), Hospital das Clínicas, 2014-01-01)
OBJECTIVE: The effects of acute continuous positive airway pressure therapy on left ventricular diastolic function and functional capacity in patients with compensated systolic heart failure remain unclear.METHODS: This ...
Follow-up study of morphology and cardiac function in rats undergoing induction of supravalvular aortic stenosis
(Sociedade Brasileira de Cardiologia (SBC), 2003-12-01)
OBJETIVO: Caracterizar, evolutivamente, o modelo experimental de hipertrofia ventricular esquerda (HVE) por indução de estenose aórtica supravalvar em ratos jovens. MÉTODOS: Ratos Wistar foram submetidos a toracotomia para ...
Food restriction-induced myocardial dysfunction demonstrated by the combination of in vivo and in vitro studies
(2002-11-01)
The aim of this study was to test the hypothesis that protein-calorie undernutrition decreases myocardial contractility jeopardizing ventricular function, and that ventricular dysfunction can be detected noninvasively. ...
Association between atherosclerotic aortic plaques and left ventricular hypertrophy in patients with cerebrovascular events
(Lippincott Williams & Wilkins, 2006-04-01)
Background and Purpose - the purpose of this research was to evaluate whether an association exists between the presence of atherosclerotic plaque in the thoracic aorta and left ventricular hypertrophy (LVH) in patients ...
Score for atrial fibrillation detection in acute stroke and transient ischemic attack patients in a Brazilian population: The acute stroke atrial fibrillation scoring system
(Faculdade de Medicina / USP, 2014-04-01)
OBJECTIVE: Atrial fibrillation is a common arrhythmia that increases the risk of stroke by four- to five-fold. We aimed to establish a profile of patients with atrial fibrillation from a population of patients admitted ...
A elevação da pressão arterial sistólica durante o teste ergométrico após transplante cardíaco: correlação com o quadro clínico e a função ventricular avaliada pela ecocardiografia sob estresse com dobutamina
(Sociedade Brasileira de Cardiologia - SBC, 2006-11-01)
OBJECTIVE: Patients who underwent heart transplantation (HTX) experience a reduction in the elevation that is usual in systolic blood pressure during exercise testing. Of unknown origin, this phenomenon varies in frequency ...
O bloqueio do sistema renina-angiotensina atenua a remodelação cardíaca de ratos submetidos a estenose aórtica
(Sociedade Brasileira de Cardiologia (SBC), 2005-04-01)
OBJETIVO: Avaliar o papel do bloqueador dos receptores AT1 e do inibidor da enzima conversora da angiotensina na remodelação cardíaca induzida por estenose aórtica em ratos. MÉTODOS: Ratos Wistar foram divididos em 4 grupos: ...
