A Trial Testing Amiodarone in Chagas Cardiomiopathy

Summary

Purpose: The ATTACH trial, as currently designed, will primarily test whether a treatment with Amiodarone for at least 6 months has a trypanocidal effect among individuals with mild-to-moderate Chronic Chagas Cardiomyopathy. A secondary goal will be to confirm, in this population, a clinical benefit from this treatment (in terms of reducing mortality or cardiac arrhythmic events), and to explore whether a potential trypanocidal effect is associated with a clinical benefit.
