Rapidly Progressing Chagas Cardiomyopathy.

Chagas disease, caused by the parasite Trypanosoma cruzi, can cause a potentially life-threatening cardiomyopathy in approximately 10-40% of afflicted individuals. The decline in cardiac function characteristically progresses over the course of many years. We report a case of Chagas disease in which the patient experienced an atypical rapid deterioration to severe cardiomyopathy over the course of 16 months. This case argues the need for increased routine surveillance for patients with confirmed T. cruzi infection, who are determined to be at high-risk for worsening cardiomyopathy. © The American Society of Tropical Medicine and Hygiene.
