Influence of lisinopril on cardiac remodeling induced by tobacco smoke exposure
(2010-08-13)
Background: To investigate the effect of lisinopril on cardiac remodeling induced by smoking. Material/Methods: Rats were allocated into 3 groups: group CON (n=8): control; group CSE (n=8): cigarette smoke exposure; group ...
Improved systolic ventricular function with normal myocardial mechanics in compensated cardiac hypertrophy
(2002-12-01)
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 ...
Prospective Echocardiographic Evaluation of the Right Ventricle and Pulmonary Arterial Pressure in Hyperthyroid Patients
(2019-08-01)
Background: Pulmonary arterial hypertension (PAH) occurs in 35% to 65% of hyperthyroid patients. Despite this high frequency, only a few authors have examined the effects of hyperthyroidism treatment on PAH and the right ...
Physical training attenuates cardiac remodeling in rats with supra-aortic stenosis
(2014-01-01)
The aim of this study was to test the hypothesis that physical training (PT) attenuates cardiac remodeling and the severity of heart failure in rats with aortic stenosis. Wistar male rats were divided in sham (S, n=10), ...
Effect of gestational protein restriction on left ventricle hypertrophy and heart angiotensin II signaling pathway in adult offspring rats
(2013)
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 ...
Ventricular remodeling and diastolic myocardial dysfunction in rats submitted to protein-calorie malnutrition
(Amer Physiological Soc, 2002-04-01)
The effects of protein-calorie malnutrition (PCM) on heart structure and function are not completely understood. We studied heart morphometric, functional, and biochemical characteristics in undernourished young Wistar ...
Fiber architecture in remodeled myocardium revealed with a quantitative diffusion CMR tractography framework and histological validation
(BIOMED CENTRAL LTDLONDON, 2012)
Background: The study of myofiber reorganization in the remote zone after myocardial infarction has been performed in 2D. Microstructural reorganization in remodeled hearts, however, can only be fully appreciated by ...
Cardiac benefits of exercise training in aging spontaneously hypertensive rats
(Lippincott Williams & Wilkins, 2011-12-01)
Objective To evaluate the effect of low-intensity chronic exercise training (ExT) on blood pressure (BP), as well as the cardiac alterations associated with hypertension in aging hypertensive rats.Methods Male spontaneously ...
Tobacco Smoke Induces Ventricular Remodeling Associated with an Increase in NADPH Oxidase Activity
(Karger, 2011-01-01)
Background: Recent studies have assessed the direct effects of smoking on cardiac remodeling and function. However, the mechanisms of these alterations remain unknown. The aim of this study was to investigate de role of ...
Cardiac remodeling: Serial analysis and indexes for early detection of ventricular dysfunctionRemodelación cardiaca: Análisis seriado e índices de detección precoz de disfunción ventricular
(2010-01-01)
Background: Supravalvar aortic stenosis (SVAS) is used to study overload-induced cardiac remodeling (CR). In this model, neither CR behavior since beginning stage nor the best parameters to identify ventricular dysfunction ...
