Participants: 30 065 (23 570 men) people seeking to obtain clinical eligibility for competitive sports.

Exercise ECG showed cardiac anomalies in 1227 athletes with normal findings on resting ECG. At the end of screening, 196 (0.6%) participants were considered ineligible for competitive sports.

Follow-up studies are needed to show if disqualification of such people would reduce the incidence of CV events among athletes.

(Age >30 years was significantly associated with an increased risk of being disqualified for cardiac findings during exercise testing.)

BMJ 21 December 2007;
