  "abstract": "Objectives:: To describe the cardiovascular manifestations and clinical course of patients with chronic Chagas cardiomyopathy at a Peruvian national hospital.\n\nMaterials and methods: : Descriptive retrospective case series (2021-2025). Nine patients with serologically confirmed Trypanosoma cruzi infection were assessed by electrocardiography, echocardiography, and/or 24-hour Holter monitoring; a predominant cardiovascular phenotype was assigned to each.\n\nResults: : The mean age was 50.1 ± 6.8 years; 55.6% were male, and 66.7% came from the Peruvian Amazon. The heart failure phenotype predominated (55.6%), with ejection fractions of 15-39%, followed by ventricular arrhythmias (22.2%) and conduction disorders (22.2%). Two patients (22.2%) received permanent pacemakers, one (11.1%) received an implantable cardioverter-defibrillator, and two (22.2%) died.\n\nConclusions: : The three classic phenotypes coexisted, with advanced disease at diagnosis. Chagas disease should be considered cases of nonischemic dilated cardiomyopathy or conduction disorders.",
