Popis: Background Acute myocarditis (AM) in athletes is a frequent source of concern. Purpose Investigate whether the way of practice has an impact on the severity of AM and on the occurrence of long-term adverse events if sport is resumed. Methods 82 athletes (≥2 hours of sport per week) who presented an AM were retrospectively included from January 2009 to December 2019. AM was defined by onset of symptoms 6 months after acute phase) heart failure, rehospitalization or recurrence. Results Mean age was 29 ± 9 years old, 77 (94%) were men, median time of practice was 5.4 ± 3.7 hours per week. Sixteen (29.5%) presented a severe AM. Practicing sport > 6 hours a week (43.8% vs. 16.7% P = 0.019) or a Mitchell's Class IIIA sport (37.5% vs. 10.6%; P = 0.008) was associated with severe AM. Practicing a Michell's Class IC sport (6.3% vs. 37.9%; P = 0.008) was associated with non-severe AM. Median follow-up was 33.8 [16.6–60], 65 (79.3%) patients resumed sport ( Fig. 1 ). In univariate Cox regression analysis, sport resumes (HR 0.97; 95% CI 0.20–4.57, P = 0.97), competition (HR 0.76; 95%CI 0.15–3.82; P = 0.74) and amount of hours of practice par week (HR 1.15; 95%CI 0.98–1.32; P = 0.06) were not associated with the occurrence of late heart failure, rehospitalization or recurrence ( Table 1 ). Conclusion In athlete's AM, the way of sport participation (static or dynamic component, practice over 6 hours a week) is associated with the presentation's severity. The return to sport after the acute phase does not seem to be associated with the occurrence of adverse events.
