Proteção miocárdica ao coração hipertrofiado: O eterno desafio
The myocardial protection allowed great advance in cardiac surgery, decreasing the mortality and making more feasible complex surgeries. Latterly, the patient population elected for cardiac procedures has been changing ...
Myocardial remodeling and dysfunction are induced by chronic food restriction in spontaneously hypertensive rats
(Elsevier B.V., 2006-11-01)
Several studies have shown alterations in hearts from animals subjected to food restriction (FR). However, few experiments in hearts evaluating pressure overload have been reported. We examined the effects of chronic FR ...
Participação do Estado Contrátil e do Relaxamento Miocárdico na Disfunção Ventricular durante a Transição Hipertrofia-Falência Cardíaca
Purpose - To investigate the participation of contractile state and relaxation in cardiac muscle dysfunction during the transition from stable hypertrophy to cardiac decompensation in aging spontaneously hypertensive rats ...
Left ventricular adaptation to chronic pressure overload induced by inhibition of nitric oxide synthase in rats
(Dr Dietrich Steinkopff Verlag, 1998-06-01)
Myocardial Remodeling In Hypertension
(NATURE PUBLISHING GROUPLONDON, 2015)
Myocardial dysfunction with increased ventricular compliance in volume overload hypertrophy
(Elsevier B.V., 2006-12-01)
The aim this study was to evaluate systolic and diastolic function in volume overload induced myocardial hypertrophy in rats.Volume overload myocardial hypertrophy was induced in thirteen male Wistar rats by creating ...
Myocardial function during chronic food restriction in isolated hypertrophied cardiac muscle
(Lippincott Williams & Wilkins, 2000-10-01)
Background: the effect of food restriction (FR) on myocardial performance has been studied in normal hearts. Few experiments analyzed the effects of undernutrition on hearts subjected to cardiac overload. The aim of this ...
Experimental myocardial hypertrophy induced by a minimally invasive ascending aorta coarctation
(Associação Brasileira de Divulgação Científica (ABRADIC), 2001-03-01)
Ascending aorta coarctation was produced by a minimally invasive technique in rabbits. Animal mortality was 5%. Morphometric and hemodynamic parameters were evaluated. A parabiotically isolated heart model was used to ...
Direct effects of colchicine on myocardial function - Studies in hypertrophied and failing spontaneously hypertensive rats
(Lippincott Williams & Wilkins, 1999-01-01)
The aging spontaneously hypertensive rat (SHR) is a model in which the transition from chronic stable left ventricular hypertrophy to overt heart failure can be observed. Although the mechanisms for impaired function in ...
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 ...
