Capacidade funcional máxima e função diastólica em portadores de cardiomiopatia chagásica sem insuficiência cardíaca congestiva

Abstract

Purpose - -AT). Left ventricular diastolic function was evaluated by conventional echocardiography (E wave, A wave and E/A ratio).Results -No significant differences occurred between the two groups with regard to FS (p=0.212)

Gas exchange during exercise in different evolutional stages of chronic Chagas' heart disease

“…This result is in accordance with preceding studies 21,22 that also did not show a significant difference between healthy individuals and patients in the undetermined form of Chagas' disease (group IA of the Los Andes classification) for variables during exercise. However, it does not agree with another study 23 . This discrepancy may reflect a greater intolerance to exercise in patients of one sample as compared with those of another sample, and even may result from factors relating to different methodologies or equipment used that may interfere with the sampling.…”

Left Atrial Function in Patients with Chronic Chagasic Cardiomyopathy

“…The s’ wave is related to longitudinal left ventricular (LV) systolic function, while the e’ wave is related to LV diastolic function. One of the advantages of using the e' wave to assess LV diastolic function is less dependence on hemodynamic loading conditions, contrary to what occurs with the E wave of the mitral flow 2 - 8 .…”

Efeitos do exercí­cio fí­sico em indiví­duos com cardiomiopatia chagásica

“…Nos indivíduos sintomáticos a doença afeta principalmente a função cardíaca, provocando a destruição das células musculares e nervosas cardíacas. isso desencadeia alterações irreversíveis na estrutura e função do coração como remodelamento miocárdico, distúrbios de condução e arritmias, o que leva consequentemente a insuficiência cardíaca e a limitações funcionais desses indivíduos [4].…”
