Resumption of physical exercise 3 months after acute myocarditis diagnosis resulted in no adverse cardiac events or worsening of left ventricular ejection fraction over a 12-month follow-up.

Does resumption of physical exercise 3 months after diagnosis of myocarditis increase adverse cardiovascular events in patients with mildly reduced or preserved LVEF?
Early resumption of physical exercise 3 months after acute myocarditis appears safe in patients with preserved or mildly reduced LVEF and no arrhythmias on screening.
International cardiovascular society recommendations to return to sports activities following acute myocarditis are based on expert consensus in the absence of prospective studies. We prospectively enrolled 30 patients with newly diagnosed myocarditis based on clinical parameters, laboratory measurements and cardiac magnetic resonance imaging with mildly reduced or preserved left ventricular ejection fraction (LVEF) with a follow-up of 12 months. Cessation of physical activity was recommended for 3 months. The average age was 35 (19-80) years with 73% male patients. One case of non-sustained ventricular tachycardia was recorded during 48-h-Holter electrocardiogram. Except for this case, all patients were allowed to resume physical exercise after 3 months. At 6- (n = 26) and 12-month (n = 19) follow-up neither cardiac events nor worsening LVEF were recorded. The risk of cardiac events at 1 year after diagnosis of myocarditis appears to be low after resumption of exercise after 3 months among patients who recover from acute myocarditis.
Patriki et al. (Mon,) conducted a cohort in Acute myocarditis (n=30). Resumption of physical exercise 3 months after diagnosis was evaluated on Adverse cardiovascular events (persistent or malignant arrhythmias, worsening LVEF, hospitalizations for heart failure, and death). Resumption of physical exercise 3 months after acute myocarditis diagnosis resulted in no adverse cardiac events or worsening of left ventricular ejection fraction over a 12-month follow-up.
