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: ...
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 ...
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 ...
Echocardiographic predictors of ventricular remodeling after acute myocardial infarction in rats
(2011-12-01)
Background: The prediction of the ventricular remodeling process after acute myocardial infarction (AMI) may have important clinical implications. Objetive: To analyze echocardiographic variables predictors of remodeling ...
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 ...
Papel da lipoperoxidação na intensificação da remodelação causada pelo betacaroteno após o infarto
(Sociedade Brasileira de Cardiologia (SBC), 2009-07-01)
FUNDAMENTO: Os mecanismos envolvidos na maior remodelação causada pelo betacaroteno após o infarto são desconhecidos. OBJETIVO: Analisar o papel da lipoperoxidação na remodelação ventricular após o infarto do miocárdio, ...
Influence of autonomic neuropathy upon left ventricular dysfunction in insulin-dependent diabetic patients
(Clinical Cardiology Publ Co, 2000-05-01)
Background: Diabetic cardiomyopathy is a well-defined complication of diabetes that occurs in the absence of ischemic, vascular, and hypertensive disease.Hypothesis: The study was undertaken to test the relationship among ...
Tolerância ao esforço em ratos com estenose aórtica e disfunção ventricular diastólica e/ou sistólica
(Sociedade Brasileira de Cardiologia (SBC), 2013-01-01)
FUNDAMENTO: A Tolerância ao Esforço Físico (TEF) é uma medida de condicionamento cardiorrespiratório. A capacidade aeróbica é reduzida na Insuficiência Cardíaca (IC), embora não haja dados disponíveis sobre esse parâmetro ...
Infliximab prevents increased systolic blood pressure and upregulates the AKT/eNOS pathway in the aorta of spontaneously hypertensive rats
(2013-01-30)
High systolic blood pressure caused by endothelial dysfunction is a comorbidity of metabolic syndrome that is mediated by local inflammatory signals. Insulin-induced vasorelaxation due to endothelial nitric oxide synthase ...
