Improved systolic ventricular function with normal myocardial mechanics in compensated cardiac hypertrophy
There still controversy about the relation between changes in myocardial contractile function and global left ventricular (LV) performance during stable concentric hypertrophy. To clarify this, we analyzed LV function in ...
Relevãncia do padrão de remodelamento ventricular no modelo de infarto do miocárdio em ratos
Background: The relevance of the remodeling pattern in the model of infarcted rats is not known. Objective: To analyze the presence of different patterns of remodeling in this model and its functional implications. Methods: ...
Ventricular systolic reserve in asymptomatic children previously treated with low doses of anthracyclines: A longitudinal, prospective exercise echocardiography study
Background: The time course of mild cardiotoxicity induced by anthracycline remains unknown. The aim of this study was to evaluate the long-term evolution of decreased myocardial reserve in children previously treated with ...
Effect of gestational protein restriction on left ventricle hypertrophy and heart angiotensin II signaling pathway in adult offspring rats
Maternal protein restriction may be a risk factor for cardiovascular disorders in adulthood. The RAS (renin-angiotensin-system) plays a pivotal role in cardiac remodeling. Components of the RAS, including angiotensin II ...
Developed pressure data may provide misinformation when used alone to evaluate systolic function in isovolumetric left ventricle preparations
(Associação Brasileira de Divulgação Científica, 1999-06-01)
We report data showing that developed pressure (DPmax) may lead to opposite conclusion with respect to maximal developed circumferential wall stress (smax) when used to assess contractile function in left ventricle isovolumic ...
