Prognostic Evaluation of Chagasic and Non-Chagasic Patients Undergoing Pacemaker Implantation and Cardiac Resynchronization in a Tertiary Center.

Background: Chagas cardiomyopathy (ChCC) is one of the causes of the implantation of pacemakers (PM) in many patients and has been associated with an adverse prognosis.

Objectives: To compare the prognosis of the chagasic and non-chagasic populations undergoing PM and cardiac resynchronizer implantation.

Methods: Observational, retrospective study, which analyzed a cohort of patients who underwent implantation of these devices, in a tertiary center, from October 2007 to December 2017, comparing the chagasic group with non-chagasic patients.

Evaluation of patients with implantable cardioverter-defibrillator in a Latin American tertiary center.

Introduction: Despite advancements in implantable cardioverter-defibrillator (ICD) technology, sudden cardiac death (SCD) remains a persistent public health concern. Chagas disease (ChD), prevalent in Brazil, is associated with increased ventricular tachycardia (VT) and ventricular fibrillation (VF) events and SCD compared to other cardiomyopathies.

Methods: This retrospective observational study included patients who received ICDs between October 2007 and December 2018.
