Left atrial dimension and new-onset atrial fibrillation in chronic Chagas disease: A competing-risk analysis of the SEARCH-Rio cohort.
BACKGROUND Atrial cardiomyopathy and atrial fibrillation (AF) complicate chronic Chagas disease (CCD). We assessed whether baseline left atrial (LA) diameter predicts new-onset AF during long-term follow-up, relates to ventricular remodeling, and whether P-wave signal-averaged ECG (P-SAECG) adds predictive value.
