Does resting ECG improve the identification of cardiovascular disorders associated with sudden cardiac death compared to the AHA 14-point evaluation in high school athletes?
Resting ECG significantly outperforms the standard AHA 14-point history and physical examination in screening high school athletes for cardiovascular conditions associated with sudden cardiac death.
Background Preparticipation cardiovascular screening in athletes is fully endorsed by major medical societies, yet the most effective screening protocol remains debated. We prospectively compared the performance of the American Heart Association ( AHA ) 14‐point screening evaluation and a resting ECG for cardiovascular screening of high school athletes. Methods and Results Competitive athletes participating in organized high school or premier/select level sports underwent cardiovascular screening using the AHA 14‐point history and physical examination, and an ECG interpreted with the Seattle Criteria. A limited echocardiogram was performed for all screening abnormalities. The primary outcome measure was identification of a cardiovascular disorder associated with sudden cardiac death. From October 2014 to June 2017, 3620 high school athletes (median age, 16 years; range 13–19; 46.2% female; 78.6% white, 8.0% black) were screened. One or more positive responses to the AHA 14‐point questionnaire were present in 814 (22.5%) athletes. The most common history responses included chest pain (8.1%), family history of inheritable conditions (7.3%), and shortness of breath (6.4%). Abnormal physical examination was present in 356 (9.8%) athletes, and 103 (2.8%) athletes had an abnormal ECG . Sixteen (0.4%) athletes had conditions associated with sudden cardiac death. The sensitivity (18.8%), specificity (68.0%), and positive predictive value (0.3%) of the AHA 14‐point evaluation was substantially lower than the sensitivity (87.5%), specificity (97.5%), and positive predictive value (13.6%) of ECG . Conclusions The AHA 14‐point evaluation performs poorly compared with ECG for cardiovascular screening of high school athletes. The use of consensus‐derived history questionnaires as the primary tool for cardiovascular screening in athletes should be reevaluated.
