PURPOSE OF REVIEW: To review the recent literature and recommendations for cardiovascular screening in young athletes.

RECENT FINDINGS: The primary purpose of the preparticipation examination is to detect the cardiovascular disorders known to cause sudden cardiac arrest in the athlete. Studies demonstrate that the traditional history and physical-based examination has a limited sensitivity, does not detect the majority of athletes with at-risk conditions, and may provide false reassurance for athletes with disorders that remain undetected. Electrocardiogram (ECG) screening increases the sensitivity of the examination to detect disease, and cost modeling suggests protocols inclusive of ECG are the only screening strategies to be cost-effective. Proper ECG interpretation that distinguishes physiologic cardiac adaptations in athletes from findings suggestive of underlying cardiac pathology is essential to avoid high false-positive rates.

SUMMARY: The goal of cardiovascular screening is to maximize athlete safety. This includes the detection of underlying cardiac disease associated with sudden cardiac death and reduction of risk through both medical management and activity modification. Greater physician education and research are needed to improve the preparticipation examination in athletes.
