Background: The predictive value of serum soluble ST2 (sST2) biomarker for diagnostics of cardiovascular pathologies is still poorly understood as well as the role of psychological stress on the risk of heart disease. Aim: This study aimed at determining the diagnostic significance of the sST2 level in athletes involved in speed-strength sports. In addition, stress as a risk factor for the development of cardiovascular pathology was assessed and analysed as well. Methods: A prospective study on Greco-Roman wrestlers was carried out at the Centre for Sports Medicine and Rehabilitation (Almaty, Republic of Kazakhstan). All participants (n = 30) were males aged 20 to 34 years. The control group consisted of volunteers (VO) (n = 30). Anthropometric and hemodynamic parameters of athletes were studied along with electrocardiography (ECG) and ECG tests. The sST2 level was determined before (BT) and immediately after (AT) training. The stress level was determined using The Perceived Stress Scale- 10 (PSS-10). Results: The average age of the athletes was 26.57 ± 3.6 years. The total training experience was 14.57 ± 4.02 years. According to the ECG data, minor deviations from the norm (13.3%) and an abnormal ECG (33.3%) were identified. Echo-CG data showed «moderate» and «pronounced changes» in 23.3% and 53.3% of cases, respectively. The sST2 level of VO (337.1 ± 61.8 pg / mL) was lower than that of BT (548.1 ± 32.6 pg / mL) (p d» 0.001). The sST2 level of AT, it was significantly higher (830.01 ± 71.6 pg / mL) than BT (p d» 0.001). The average and high level of stress among athletes was in 43.3% and 56.7% of cases, respectively. Stress increased the likelihood of developing distinctly abnormal ECG (OR = 1.06, 95% CI 1.01-1.08; p = 0.02). The stress level showed a positive correlation with the sST2 level (r = 0.752, p = 0.01). The sST2 concentration and categorical echocardiography data demonstrated a dependent positive correlation (r = 0.6, p = 0.01). Conclusions: Athletes sST2 levels exceeded thresholds both before and after training. Moreover, the relationship between an increase in sST2 levels and abnormal ECG abnormalities and a high level of stress in athletes was determined. sST2 concentration was associated with cardio-pulmonary stress triggered by the cumulative exercise dose as well as with lifelong psychological stress. Our findings indicate that the elevated sST2 concentrations in athletes could be used as the predictive value. However, clinical relevance and results validity require further intensive studies.
