Background
Chagas disease is a major cause of heart failure in Latin America. Many Chagas disease patients live in rural areas under poor economic conditions with limited access to formal echocardiography. Point-of-care ultrasound is rapidly gaining recognition as a powerful diagnostic tool in such fields as emergency medicine, intensive care, and primary care, but is not commonly utilized in Chagas-endemic regions. In this study we sought to determine the reproducibility of point-of-care cardiac ultrasound performed by a non-cardiologist in Chagas patients.
