[Maximal functional capacity, ejection fraction, and functional class in Chagas cardiomyopathy. Are these indices related?].
OBJECTIVE Left ventricular ejection fraction (LVEF) and maximal functional capacity (VO2max) have both been shown to be related to a poor long-term survival in Chagas' disease patients. The aim of this study was to estimate the potential association of VO2max, LVEF, and NYHA functional class in patients with Chagas' disease cardiomyopathy. METHODS One hundred four male patients, aged 40.3+/-9...
متن کامل[Maximal functional capacity and diastolic function in patients with cardiomyopathy due to Chagas' disease without congestive heart failure].
PURPOSE To identify early cardiac dysfunctions in asymptomatic patients with Chagas' cardiomyopathy. METHODS We studied 38 male individuals: control group consisting of 20 sedentary normal individuals and Chagas' group, of 18 asymptomatic patients with Chagas' disease, with suggestive electrocardiographic alterations and normal fractional shortening (FS) on echocardiogram. Both groups were su...
متن کاملFunctional capacity and right ventricular function in patients with Chagas heart disease.
AIMS Right ventricular (RV) dysfunction is an important factor on effort tolerance in cardiopulmonary diseases. Nevertheless, the role of RV function in predicting exercise capacity in patients with Chagas disease has not been reported. This study aims to evaluate whether RV function assessed by tissue Doppler can predict functional capacity in patients with Chagas heart disease. METHODS AND ...
متن کاملChagas' Cardiomyopathy
Background The fundamental determinant of the natural history of Chagas' disease is cardiac involvement. Methods and Results We studied 104 male patients with congestive heart failure due to Chagas' disease to estimate the survival distribution function and to evaluate age, functional class (FC), maximal oxygen consumption (Vo2max ), and ejection fraction (EF) as predictors of survival. Statist...
متن کاملFunction of the Left Atrium in the Chagas’ Cardiomyopathy
Results The age was 48±13 years old and 69% were men. Most of patients (88%) were in functional classes I and II, under a conventional treatment for cardiac insufficiency. The fraction of ejection of the left ventricle was 39±13%. The indicators of diastolic function associate to those of systolic function and the functional class. The carriers of pseudonormal or restrictive pattern of diastoli...
