Progression of Chagas Cardiomyopathy

Later manifestations of Chagas cardiomyopathy may include:

• Complex ventricular extrasystoles
• Non-sustained and sustained ventricular tachycardia
• Sinus node dysfunction with severe sinus bradycardia
• High degree atrioventricular blocks
• Apical aneurysm
• Pulmonary and systemic thromboembolic phenomena
• Progressive dilated cardiomyopathy with congestive heart failure

Patients may have both brady- and tachyarrhythmias.

Patients may complain of palpitations, presyncope, syncope, and/or symptoms of cardiac insufficiency.

Chagas cardiomyopathy carries a high risk of sudden death from ventricular arrhythmias, complete heart block, or emboli.
