Study flow chart and outcome of 2578 athletes >35 years screened for HRCC.

A total of 2578 athletes > 35 years had ECG-inclusive screening for HRCC. Of the 507 with screening abnormalities, 13 were excluded (incomplete data). Of the included 494 athletes, the ECG at rest was abnormal applying the ESC-2005 criteria in 308, applying the Seattle criteria in 212, and International criteria in 140. The corresponding ECG-detected HRCC were 46, 36, and 33, respectively.

ACM: arrhythmogenic cardiomyopathy; AV: aortic valve; AVS: moderate or severe aortic valve stenosis; BAV: bicuspid aortic valve; CAD: coronary artery disease; cAVB: complete AV-block; DCM: dilated cardiomyopathy; HCM: hypertrophic cardiomyopathy; HRCC: high-risk cardiovascular conditions; LRCC: low-risk cardiovascular conditions VT: ventricular tachyarrhythmia.
