Abstract
Background: Although rare, sudden cardiac death (SCD) is a tragic event for young sports participants and has catastrophic impact on the community. Hypertrophic cardiomyopathy (HCM) is a leading cause of SCD in sports. Comprehensive initial pre-participation physical evaluation (CIPPE) is mandated for middle school, and junior and senior high school students by Pennsylvania Interscholastic Athletic Association (PIAA) primarily for reducing potential sports-related injuries and SCD. Prospective data has been limited in this age group in regard to the prevalence of HCM. Methods: Between 2015 and 2023, we prospectively screened 424 students [age 10-21 (15±2) years, 60% male, 64% Caucasian) referred for cardiovascular disease pre-participation screening based on at least one positive response on the 14-point AHA questionnaire during CIPPE. Evaluation included 12-lead ECG and rhythm strip (100%), transthoracic echo (96.4%), ambulatory heart rhythm monitor (3.8%), treadmill exercise ECG (14.5%), stress echo (2.1%), and cardiac MRI (0.9%). Results: Overall, 1 (0.24%) student was diagnosed with definitive and two were diagnosed with probable HCM [Table-1]. Conclusion: In this prospective cohort of middle school and junior and senior high school students with at least one positive response to the 14-point AHA questionnaire, 1 (0.24%) had definitive and 2 (0.47%) had probable phenotypic HCM.
