Successful treatment of suspected early form of chronic Chagas cardiomyopathy: a case report.

Background: Chagas disease, caused by the protozoan Case summary: We present a case of Chagas disease in a 75-year-old patient originally from El Salvador who presented to our Canadian tertiary centre with heart failure and atrial fibrillation/flutter. The patient had dilated cardiomyopathy with severely reduced systolic function, which was thought to be early Chagas cardiomyopathy after confirmatory positive serologies for Discussion: The American Heart Association recommends considering treatment of early chronic Chagas cardiomyopathy with anti-trypanosomal therapy. Our case highlights the importance of multidisciplinary collaboration in the diagnosis of early Chagas cardiomyopathy and critical timing of benznidazole, as effectiveness is limited in late disease due to myocardial cell-death programme. Although the historical BENEFIT study is known to not have shown mortality reduction, we advocate that the significant reduction in cardiovascular-related hospitalizations should be considered for symptomatic patients with early Chagas cardiomyopathy with the potential benefit of improving cardiac function and avoiding need for heart transplantation.
