Abstract

Objective. To study the prevalence of thrombosis allelic polymorphisms in patients with severe angina who have indications for myocardial revascularization. Design and methods. The study included 105 patients (87 men and 18 women) aged from 33 to 70 years who had angina III–IV functional class, with indications for myocardial revascularization. All the patients studied polymorphism of the inhibitor of tissue plasminogen activator I type (675 4G/5G) (PAI-I), mutations of the factor II-prothrombin (20210 G / A), mutations of the factor V Leiden (Arg 506 Gln) and polymorphism of the methylenetetrahydrofolate reductase (Ala 222 Val) (MTHFR). Results. The prevalence of these mutations and polymorphisms in patients with severe angina requiring revascularization of the myocardium in 3 times greater than in the group of healthy adolescents. Our data showed that the risk of severe angina is directly proportional, and the age of the clinical debut of CHD is inversely proportional to the number of studied genetic defects. Thrombophilic polymorphisms studied genes increases the effects of other cardiovascular risk factors such as male sex, smoking and leads to an earlier debut of clinical CHD. Conclusion. It is necessary to form the strategy of genetically-based population policy for the prevention of atherosclerosis, including coronary. Healthy persons with diagnosed thrombosis polymorphisms are need of active primary prevention of cardiovascular disease.
