Background: The lack of clear standards for medical supervision of athletes considerably limits the ability to diagnose and prevent overstrain of the cardiovascular system. To date, in the Republic of Kazakhstan, an assessment of the significance of early cardiomarkers, reflecting the state of maladjustment of the heart to physical exertion among highly qualified athletes involved in martial arts, has not been performed. Aims: The aim of this study is to determine the level and diagnostic significance of cardiac biomarker IL1RL1 (sST2 - serum-soluble) and the role of psychological stress on the risk of cardiovascular disease in qualified sport veterans engaged in speed--strength sports. Methods: A prospective study on wrestlers was performed at the Centre for Sports Medicine and Rehabilitation (Almaty, Republic of Kazakhstan). All participants (n = 30) were males aged 30 to 44 years s, masters of sports of international class, and honoured masters of sports). The control group consisted of volunteers (VO) (n = 30). The sST2 level was determined before (BT) and immediately after (AT) training. Anthropometric and hemodynamic parameters of athletes were studied along with electrocardiography and echocardiography tests. Results: The average age of 30 athletes was 36.3 ± 0.5 years; the largest proportion of athletes was 35-39 years old (66.7%, n = 20); 6 sports veterans (20%) were 30-34 years old; the smallest proportion of athletes was under 40-44 years old (13.3%, n = 5). According to the electrocardiography (ECG) data, minor deviations from the norm (16.6 %) and abnormal ECG (30%) were identified. The echo-CG data showed "moderate" and "pronounced changes" in 40.0% and 60.0% of cases, respectively. The sST2 level of VO (337.1 ± 61.8 pg/mL) was lower than that of BT (570.1 ± 32.6 pg/mL) and AT (768.7 ± 71.6 pg/mL) (p < 0.05).IL1RL1 (ST2) showed high sensitivity in determining the maladaptation of the cardiovascular system to physical exertion in highly qualified sports veterans (p > 0.05). Conclusion: Athletes' sST2 levels exceeded thresholds both before and after training. Our findings indicate that the elevated sST2 concentrations in athletes can be used as the predictive value show maladaptation of the cardiovascular. However, it requires further intensive studies.
