Distinct early repolarisation patterns in male Brazilian soccer players: insights from a multicentre study
Background Early repolarisation (ER) is commonly observed during cardiovascular screenings of young athletes and can present with various morphologies. However, its prevalence and clinical significance in male Brazilian soccer players have not been characterised. This study aimed to compare the prevalence of different ER patterns and assess their potential clinical significance in this population. Methods In this multicentre observational study, we analysed ECG data from male Brazilian soccer players who underwent preparticipation evaluations at 83 professional clubs across Brazil’s five geographic regions between February 2002 and August 2024. Our analysis included white, mixed-race and black athletes, as well as seven distinct ER morphologies. Poisson regression with robust variance was used to derive age-adjusted prevalence ratios for the different ER morphologies. Results We included 6353 athletes (median (IQR) age: 19 (16–23) years; 2556 white, 2071 mixed-race and 1726 black indiv
