Key result
Trypanosoma cruzi immune evasion and sustained proinflammatory responses cause autonomic dysfunction, microvascular ischemia, autoimmunity, and myocardial fibrosis in chronic Chagas cardiomyopathy.
Why the study?
The mechanisms involved in cardiac damage in Chagas disease remain an active field of study.
This review synthesizes the immunopathological mechanisms of Chagas cardiomyopathy, highlighting how Trypanosoma cruzi persistence, immune evasion, microvascular dysfunction, and autoimmune responses drive chronic myocardial fibrosis and heart failure.

May inform immunomodulatory strategies in Chagas cardiomyopathy; leaves open prospective validation before clinical adoption.
In Chagas disease, the mechanisms involved in cardiac damage are an active field of study. The factors underlying the evolution of lesions following infection by Trypanosoma cruzi and, in some cases, the persistence of its antigens and the host response, with the ensuing development of clinically observable cardiac damage, are analyzed in this review.

Alba-Alvarado et al. (2023) conducted a review in Chagas disease (Trypanosoma cruzi infection and Chagas cardiomyopathy). Trypanosoma cruzi infection was evaluated on Immunopathological cardiac damage and fibrosis in Chagas disease. Trypanosoma cruzi immune evasion and sustained proinflammatory responses cause autonomic dysfunction, microvascular ischemia, autoimmunity, and myocardial fibrosis in chronic Chagas cardiomyopathy.
