Best Practice Case Studies-Case 117 Asset 2 Recommendations for Athletes with Cardiac Channelopathies

Pdf Summary

This AHA/ACC scientific statement addresses competitive sports participation for athletes with cardiac channelopathies, genetically mediated electrical disorders that can cause syncope, seizures, or sudden cardiac arrest despite a structurally normal heart. Major conditions include long-QT syndrome (LQTS), catecholaminergic polymorphic ventricular tachycardia (CPVT), Brugada syndrome (BrS), early repolarization syndrome, short-QT syndrome, and possibly idiopathic ventricular fibrillation.<br /><br />The statement emphasizes that these disorders are potentially lethal but often treatable, and that athletes should be evaluated by a highly experienced heart rhythm specialist or genetic cardiologist before return-to-play decisions are made. It notes that new genetic testing has revealed many concealed, genotype-positive/phenotype-negative individuals, but there is no strong evidence that such athletes experience events during sport solely because of a positive genetic test.<br /><br />Key precautions for affected athletes include avoiding QT-prolonging drugs, avoiding Brugada-triggering drugs, maintaining hydration and electrolytes, preventing or treating fever and heat illness, carrying a personal automated external defibrillator, and having an emergency action plan with team officials.<br /><br />The recommendations are:<br />- Symptomatic athletes with suspected or diagnosed channelopathy should be restricted from all competitive sports until fully evaluated, treated, informed, and symptom-free on therapy for at least 3 months.<br />- Asymptomatic athletes with concealed channelopathy may participate in all sports with precautions.<br />- Participation may be considered for certain athletes with manifest or previously symptomatic BrS, early repolarization syndrome, short-QT syndrome, or LQTS after treatment and 3 months without symptoms.<br />- CPVT is treated more restrictively: competitive sports are generally not recommended except class IA sports, due to higher exercise-triggered risk.<br /><br />Overall, the document supports individualized, specialist-guided decisions rather than blanket disqualification.
