Bethesda Guidelines

  • Before returning to competitive sports, athletes should undergo a
    • resting echocardiogram
    • 24-hour Holter monitoring
    • an exercise ECG
  • no less than 3 to 6 months after the initial illness (Class I; Level of Evidence C}.[1]
  • It is reasonable that athletes resume training and competition if all of the following criteria are met
    • Ventricular systolic function has returned to the normal range.
    • Serum markers of myocardial injury, inflammation, and heart failure have normalized.
    • Clinically relevant arrhythmias such as frequent or complex repetitive forms of ventricular or supraventricular ectopic activity are absent on Holter monitor and graded exercise ECGs.
  • At present, it is unresolved whether resolution of myocarditis-related LGE should be required to permit return to competitive sports.
  • Athletes with probable or definite myocarditis should not participate in competitive sports while active inflammation is present.
  • This recommendation is independent of age, gender, and LV function (Class III; Level of Evidence C).
