American Trypanosomiasis (Chagas Disease)

American trypanosomiasis is caused by a parasite endemic of the Americas. Current migration has globalized Chagas disease. Acute infection usually resolves spontaneously. Nonetheless, 20% to 40% develop cardiomyopathy 20 to 30  years later. Progression to cardiomyopathy is devastatingly rapid, manifesting with heart failure and sudden death. Etiologic treatment is highly effective and recommended in those with acute infections, congenital infections, and parasite reactivation, and women of childbearing age, but in asympt omatic Trypanosoma cruzi carriers and patients with early cardiomyopathy remains controversial and under investigation. Progression of heart failure is rapid and accounts for most of the morbidity and related mortality.
