Objective: Structured electrocardiography (ECG) analysis is used to screen athletes for high-risk cardiovascular conditions (HRCC) to prevent sudden cardiac death. ECG criteria have been specified and recommended for use in young athletes ≤ 35 years. However, it is unclear whether these ECG criteria can also be applied to master athletes >35 years.
Aim: The purpose of this study was to test whether the existing ECG criteria for detecting HRCC in young athletes can be applied to master athletes.
Methods: We conducted a cross-sectional study among athletes >35 years screened for HRCC between 2006 and 2010. We performed a blinded retrospective analysis of master athletes' ECGs, separately applying European Society of Cardiology (ESC)-2005, Seattle, and International criteria. HRCC were defined using recommendations from the international cardiac societies American Heart Association and American College of Cardiology, and ESC, based on ECG screening and cardiovascular evaluation (CVE).
Results: We included 2578 master athletes in the study, of whom 494 had initial screening abnormalities mandating CVE. Atrial enlargement (109, 4.1%) and left ventricular hypertrophy (98, 3.8%) were the most common ECG abnormalities found using the ESC-2005 or Seattle criteria. Applying the International criteria, ST-segment deviation (66, 2.6%), and T-wave inversion (58, 2.2%) were most frequent. The ESC-2005 criteria detected more HRCC (46, 1.8%) compared with the Seattle (36, 1.4%) and International criteria (33, 1.3%). The most frequently detected HRCC was coronary artery disease (24, 0.9%).
Conclusion: ECG criteria recommended for use in young athletes can be applied to master athletes' ECGs to detect HRCC. The ESC-2005 criteria had the highest sensitivity for detecting HRCC among master athletes.
