Arrhythmias & electrophysiologyCohort study

Programmed ventricular stimulation for risk stratification in symptomatic athletes with nonischemic left ventricular scar and preserved ejection fraction

EuropacePublished

  • Prospective cohort study
  • consecutive enrolment

23 electrophysiological study (EPS)+ athletes received an ICD (18 transvenous, 5 subcutaneous); 16 EPS- athletes received an implantable loop recorder

Authors' conclusion

In symptomatic athletes with non-ischaemic LV scar and preserved LVEF, inducibility at EPS identifies a subgroup at higher risk of MAE, whereas non-inducibility is associated with a low event rate.

Study context

Population
Symptomatic athletes with non-ischaemic left ventricular (LV) scar and preserved left ventricular ejection fraction (LVEF) (≥50%) undergoing EPS
Participants
72 athletes
Exposure
Inducible vs non-inducible at EPS with programmed ventricular stimulation (PVS)
  • EPS+n = 23
  • EPS-n = 49reference
Outcome
Major arrhythmic events: sudden cardiac death, sustained ventricular tachycardia/ventricular fibrillation, or appropriate implantable cardioverter-defibrillator therapy

Main finding

As reported in the abstract

Event-free survival from major arrhythmic events (MAE) · 50 months
  • 11 major arrhythmic events during median follow-up of 42 months: 9 among inducible athletes (all terminated by appropriate ICD therapy), 2 among non-inducible athletes (resuscitated, then ICD)
  • EPS+ vs EPS-: P < 0.001
  • log-rank test

Observational data: associations, not effects.

Further findings

Arrhythmic deaths · median follow-up 42 months

No arrhythmic deaths occurred during follow-up
