Baseline characteristics and laboratory findings of the study population OP-001 Ventricular arrhythmias prediction in bodybuilders Kadir Uğur Mert, Muhammet Dural, Serdar İlgüy, Gurbet Özge Mert, Kemal İskenderov, Taner Ulus Department of Cardiology, Eskişehir Osmangazi University Faculty of Medicine, Eskişehir Background and Aim: Arrythmias are often recorded in strength training athletes without cardiovascular abnormalities but also may be a sign of an underlying cardiovascular disease which predicts risk of sud- den cardiac death(SCD). Nowadays, bodybuilding is a popular sport among adolescents. There was lack of studies comparing bodybuilders with healthy controls by excluding anabolics in arrythmias. We aimed to evaluate structural, functional and electrical characteristics of the bodybuilders’ heart comparing with control subjects. Methods: In this study, 35 male competitive bodybuilders and 35 age-, gender-, body mass index- matched healthy control subjects were evaluated. A detailed cardiovascular and systemic examination was per- formed at the beginning of the study with demographic data and anthropometric measures. Biochemical ACE: Angiotensin converting enzyme; ARB: Angiotensin receptor blocker; TSH: Thyroid-stimulating hormone. and haemotologic, echocardiographic, 24 h holter recordings, and ECG measurements obtained from all participants. Table 2. Conventional echocardiographic parameters and atrial conduction times Results: VAs encountered significantly more frequently in bodybuilders than control group (Table). QT and of the two groups QTc were not significantly different among groups. Tp-e interval, Tp-e/QT ratio, and Tp-e/QTc ratio were significantly higher in bodybuilders group compared to the control group (constantly p<0.001) (figure). There were a positive correlation between Tp-e interval, Tp-e/QT ratio, and Tp-e/QTc ratio with RV and arrythmias. Conclusions: Prolonged repolarization are common in athletes, even if their predictive value is unclear. In this study, alteration in ventricular repolarization were positively correlated with RV dimensions, thus we postulated that arrythmias, exclusively in strength athletes, may be predicted by evaluating RV echocardio- graphically and dispersions of repolarization in ECG. Finally, SCD could be evitable in strength athletes with this kind of reasonable and applicable interpretation.
