Impact of cardiac structure and function on exercise intolerance in Chagas cardiomyopathy: Insights from CPET and echocardiography.

Introduction: Chronic Chagas cardiomyopathy (CCC), the most severe clinical condition of Chagas disease, often leads to a reduction in functional capacity and the appearance of symptoms such as fatigue and dyspnea on exertion. However, its determinant factors remain unclear. We aimed to evaluate the peak oxygen consumption (VO) in patients with CCC and identify its determining factors.

Functional Status in Peripheral Arterial Disease: Rehabilitated Versus Nonrehabilitated.

Background: To analyze patient perception of functional status related to activity and participation of rehabilitated and nonrehabilitated individuals with peripheral arterial disease.

Methods: Cross-sectional study assessing the activity and participation domain using the Human Activity Profile (HAP) questionnaire and the Participation Scale, respectively. Groups were compared using Chi-squared test and unpaired t-test.
