Relevãncia do padrão de remodelamento ventricular no modelo de infarto do miocárdio em ratos
(2010-10-01)
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: ...
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 ...
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 ...
Ventricular Systolic Reserve in Asymptomatic Children Previously Treated With Low Doses of Anthracyclines
(2007-10-15)
Doppler echocardiography has been used for the diagnosis of anthracycline-induced cardiotoxicity. However, few data are available that include asymptomatic children previously treated with a low cumulative dose of this ...
Diastolic function is associated with quality of life and exercise capacity in stable heart failure patients with reduced ejection fraction
(2013-09-01)
Exercise capacity and quality of life (QOL) are important outcome predictors in patients with systolic heart failure (HF), independent of left ventricular (LV) ejection fraction (LVEF). LV diastolic function has been shown ...
Dysautonomia and ventricular dysfunction in the indeterminate form of Chagas disease
(Elsevier B.V., 2006-11-10)
Background: the associations between autonomic function and biventricular function in patients with the indeterminate form of Chagas disease remains to be elucidated.Methods: In 42 asymptornatic patients and 19 healthy ...
Changes in Myocardial Perfusion Correlate With Deterioration of Left Ventricular Systolic Function in Chronic Chagas` Cardiomyopathy
(ELSEVIER SCIENCE INC, 2009)
OBJECTIVES This study aimed at analyzing the association between myocardial perfusion changes and the progression of left ventricular systolic dysfunction in patients with chronic Chagas` cardiomyopathy (CCC). BACKGROUND ...
Left ventricular sphericity index predicts systolic dysfunction in rats with experimental aortic regurgitation
(Amer Physiological Soc, 2014-05-01)
Although an increased left ventricular (LV) diastolic diameter (DD) and a decreased ejection fraction have been used as markers for the surgical replacement of an insufficient aortic valve, these signals may be observed ...
Recurrencia de miocardiopatía por estrés posterior a terremoto en Chile: Reporte de un caso clínico
