Functional predictors of poor outcomes in Chagas cardiomyopathy: The value of end-tidal carbon dioxide at peak exercise

•PETCO2 peak and VO2peak were lower in chagas cardiomyopathy patients with adverse events.•PETCO2 peak and VO2peak are independent predictors of worse prognosis.•PETCO2 peak and VO2peak lower than 32 mmHg and 20 mL.kg.min identify worse prognosis. Functional impairment can be detected from the onset...
