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 ...
Aldosterone Blockade Reduces Mortality without Changing Cardiac Remodeling in Spontaneously Hypertensive Rats
(Karger, 2013-01-01)
Background: The role of aldosterone blockers during transition from long-term compensated hypertrophy to dilated failure is not completely understood. In this study we evaluated the effects of early administration of ...
Myocardial contractility impairment with racemic bupivacaine, non-racemic bupivacaine and ropivacaine. A comparative study
(Acta Cirúrgica Brasileira, 2015)
To study racemic bupivacaine, non-racemic bupivacaine and ropivacaine on myocardial contractility. Isolated Wistar papillary muscles were submitted to 50 and 100 mM racemic bupivacaine (B50 and B100), non-racemic bupivacaine ...
Direct effects of colchicine on myocardial function - Studies in hypertrophied and failing spontaneously hypertensive rats
(Lippincott Williams & Wilkins, 2014)
The Dysfunctional Scenario of the Major Components Responsible for Myocardial Calcium Balance in Heart Failure Induced by Aortic Stenosis
(2022-01-01)
Background: Maladaptive cardiac remodelling is characterized by diastolic and systolic dysfunction, culminating in heart failure. In this context, the dysfunctional scenario of cardiac calcium (Ca2+) handling has been ...
A administração precoce de hormônio de crescimento resulta em efeitos deletérios na remodelação ventricular após o infarto agudo do miocárdio
(2005-02-01)
Objective: To assess the effect of growth hormone (GH) on myocardial remodeling in infarcted rats. Methods: This study comprised 24 Wistar rats divided into 3 groups as follows: 1) AMI-GH group - comprising 8 rats that ...

Myocardial dysfunction induced by food restriction is related to calcium cycling and beta-adrenergic system changes
(Elsevier B.V., 2003-07-01)
Food restriction (FR) has been shown to promote myocardial dysfunction in rats. The aim of this study was to verify the participation of calcium and beta-adrenergic system on myocardial mechanical alteration in rats submitted ...
