Electrocardiographic values associated with Serpain (PAI-1) gene mutation sensitivity in young athletes for forecasting cardiovascular disorders

Aim. The article deals with establishing the peculiarities of ECG contour analysis in athletes with various SERPINE1 (PAI-1) genotypes depending on their gender. Materials and methods. We examined 200 athletes from national teams, including 107 boys aged 14.95 ± 1.57 and 93 girls aged 15.04 ± 1.67. ECG registration was performed in standard conditions using SENSITEG 1003 equipment. SERPINE1 PAI-1 gene mutation was assessed with the help of polymerase chain reaction using REALTIME DNA-technologies. We processed the results of the study using SPSS integrated statistical system. Results. We revealed that 44.1% and 55.1% of female and male athletes, respectively, possess SERPINE1 (PAI-1) gene heterozygous form. Dominant genotype was revealed in 23.7% and 33.6% of female and male athletes, respectively, while recessive genotype was found in 32.3% and 11.2% of female and male participants, respectively. Prolonged QRS, P intervals, associated with SERPINE1 (PAI-1) recessive genotype, are more typical for male participants (7-10%). Decreased HR and alpha angle values in persons with recessive genotype are 1.7 and 2.7 times more common for female athletes. Conclusion. We revealed electrocardiographic indicators, associated with SERPINE1 (PAI-1) gene mutation in young athletes. These indicators are significant for the assessment of cardiovascular disease risks. It was established that persons with SERPINE1 (PAI-1) 4G/4G genotype can practice professional sports only under the supervision of a cardiologist.
