Assessment of longitudinal myocardial stiffness is not enough to evaluate diastolic function.
(Japanese Circulation Soc, 2013-02)
In the 1960 s, the first studies of diastolic function appeared and from there the interest in this phase of the cardiac cycle increased. Such interest has continued to the present day, when systole and diastole are equally ...
Short-term diabetes attenuates left ventricular dysfunction and mortality rates after myocardial infarction in rodents
(Faculdade de Medicina / USP, 2011)
OBJECTIVES: To investigate the effects of hyperglycemia on left ventricular dysfunction, morphometry, myocardial infarction area, hemodynamic parameters, oxidative stress profile, and mortality rate in rats that had undergone ...
Isoproterenol-induced hypertrophy may result in distinct left ventricular changes
(Blackwell Science Asia, 2000-05-01)
1. the aim of the present study was to analyse the possible lack of uniformity in isoproterenol (ISO)-induced myocardial hypertrophy.2. Data obtained for isovolumic hearts isolated from 20 rats treated with ISO (0.3 mg/kg ...
Myocardial Remodeling after Large Infarcts in Rat Converts Post Rest-Potentiation in Force Decay
(ARQUIVOS BRASILEIROS CARDIOLOGIARIO DE JANEIRO, 2012)
Background: Post-rest contraction (PRC) of cardiac muscle provides indirect information about the intracellular calcium handling. Objective: Our aim was to study the behavior of PRC, and its underlying mechanisms, in rats ...
Food restriction does not impair myocardial mechanics during the healing period of myocardial infarction in the rat
(Elsevier B.V., 2005-12-01)
Papillary muscle mechanics were studied in 4 groups of rats: control (C) noninfarcted (n = 9), C infarcted (n = 9), food-restricted (FR) noninfarcted (n = 8) and FR infarcted (n = 9). Food-restricted animals were fed with ...
