Incidence of ventricular arrhythmias after stem cell therapy in patients with Chagas cardiomyopathy.

Background: Treatment with stem cells in several cardiomyopathies may be related to the increase in arrhythmias.

Objectives: To determine whether intracoronary injection of stem cells in patients with Chagas cardiomyopathy is associated with increased incidence of ventricular arrhythmias, compared to the Control Group.

Methods: A retrospective cohort study that evaluated the medical records of 60 patients who participated in a previous cross-sectional study.
