1F53.2

ICD-11 MMS 2026-01

Chronic Chagas disease with heart involvement

Description

A disease caused by a chronic infection with the protozoan parasite Trypanosoma cruzi. This disease commonly presents with severe malaise or cardiac involvement (such as cardiomyopathy, cardiac failure, thromboembolism, bradyarrhythmias, tachyarrhythmias, apical aneurysms, or cardiac arrest). Transmission is by direct contact with faeces from an infected triatomine bug, vertical transmission, iatrogenic transmission, or ingestion of contaminated food or water. Confirmation is by identification of Trypanosoma cruzi in a blood sample.
