Introduction Sudden cardiac death (SCD) is an important cause of morbidity in competitive athletes. Pre-participation evaluation (PPE) is mandatory for most sporting organisations. The ECG plays a very important diagnostic role and is included in most screening algorithms. PPE for athletes ≥14 years registered with the National Football Association is now mandatory. Study objectives: The objective of this study was to assess the diagnostic yield of PPE in a group of elite Maltese football players competing at national level. Methodology Players selected at national level (years 2020-2022) underwent PPE (history, physical examination, and resting ECG). Senior team players also underwent echocardiography (biannually) as per regulations. Data was tabulated and analyzed in Microsoft Excel. Results 300 athletes (69% male) were selected in this timeframe. 10.6% (n=32) required referral for secondary evaluation, equating to 1 in 11 athletes screened. Referrals were more frequent in male vs female athletes (22.1% vs 10.2%, p=0.005). Most referrals were from the men’s senior’s squad (22.5%), followed by the men’s U17 squad (21.7%) and 20% of the men’s U15 team. The ECG was the commonest reason for referral to a sports cardiologist (n=23, 71.8%). The commonest abnormal ECG patterns included anterior TWI (n=9, 3.0%), inferior/lateral TWI (n=6, 2.0%) and WPW (n=2, 0.7%). 108 (36.0%) had echocardiography as a first line screening modality. This was abnormal in a fifth of those referred (n=7, 21.9%), 4 of these had a normal ECG. 3 (1.0%) athletes were diagnosed with a condition linked to SCD (n=2 WPW, n=1 HCM). Another 5 (1.7%) athletes were diagnosed with a cardiac disorder (n=1 left ventricular outflow tract ectopy, n=1 dilated aortic root, n=1 aortic regurgitation, n=1 atrial septal defect, n=1 mitral regurgitation). Echocardiography doubled the diagnostic yield (1.3% vs 2.7%), with 3 athletes having otherwise a normal history, physical examination and ECG. 1 in 38 athletes (2.7%) were given a cardiac diagnosis, 1 in 100 athletes (1.0%) were labelled with a condition linked to SCD. Conclusion The referral rate is comparable to that reported in international screening programs, higher in males. The ECG was the commonest reason for referral. The overall diagnostic yield equates to 2.7%, while 1.0% were given a diagnosis linked to SCD. The higher diagnostic yield in this population highlights the importance of raising awareness about heart disease and PPE in young athletes.
