ABSTRACT
We investigated the association of gene IL6 G(-174)C polymorphism and gene IL10 G(-1082)A polymorphism with coronary artery disease (CAD) in the Russian population. A total of 1145 patients with CAD diagnose on the basis of clinical studies in cardiological hospitals of Moscow, St -Petersburg, Kazan, Chelyabinsk, Perm, Stavropol and Rostov-on-Don. Supervision term was 9.10 +/- 5.03 months (the maximum term 18 months). In case of gene IL10 G(-1082)A polymorphism we determined that patients with CAD diagnose and A alleles gene IL10 had unfavorable outcome more often than patients with homozygous G alleles. Survival time from end point from carrier genotype GA and AA is 11.68 +/- 0.67 months against 12.69 +/- 0.65 months from carrier phenotype GG gene IL10 (chi2 = 4.13, p = 0.042). The group studied do not differ significantly with respect to the distributions of gene IL6 G(-174)C alleles and genotypes. However in case combined group studies of gene IL10 G(-1082)A polymorphism and IL6 G(-174)C polymorphism we determined that patients with CAD diagnose and carrier genotype GG gene IL6 and genotype GA and AA gene IL10 had unfavorable outcome more often (survival time 11.01 +/- 1.24 months) than patients with genotype CC and CG gene IL6 and genotype GG gene IL10 (survival time 13.28 +/- 0.83 months) chi2 = 10.23, p = 0.017. The obtained data allows assuming the important role of the IL6 and IL10 genes which are responsible for functioning of inflammation system, in the accelerated formation of failures at the patients who had a coronary syndrome.

We investigated the association of polymorphisms of genes FGB G(-455)A and PROCC(-1654)T with coronary artery disease (CAD) in the Russian population. A total of 1145 patients with CAD diagnose on the basis of clinical studies in cardiological hospitals of Moscow, St. Petersburg, Kazan, Chelyabinsk, Perm, Stavropol and Rostov-on-Don. Supervision term was 1.14 +/- +/- 0.33 years (the maximum term 3.2 years). The group studied do not differ significantly with respect to the distributions of G(-455)A alleles and genotypes. However in case of gene PROC C(-1654)T polymorphism we determined that patients with CAD diagnose and Talleles of PROC gene had unfavorable outcome more often than patients with homozygous C alleles. Survival time from end point from carrier phenotype TT and CTis 2.19 +/- 0.18 r. years against 2.46 +/- 0.16 from carrier phenotype CCgene PROC. The obtained data allows to assume the important role of the genes which are responsible for functioning of system of a hemostasis, in the accelerated formation of failures at the patients who had a coronary syndrome.

Genetic factors determine resistance or susceptibility to development of many cardiovascular diseases. The study of polymorphisms of gene candidayes is a perpective approach in detection of risk and prognosis of outcomes of cardiovascular diseases. Most studied with the help of proven base genes are: ACE gene, angiotensin II gene, NO synthase gene, and estrogen receptor gene. Polymorphism of candidate genes has various clinical consequences in men and women. Despite small number of data devoted to gender differences our work sums up existing results of studies of polymorphisms of above mentioned 4 genes with consideration of gender peculiarities.

For the study of contribution of atrial fibrillation (AF) during acute coronary syndrome (ACS) in long-term prognosis after clinical stabilization we examined 453 patients admitted to Moscow hospitals and followed them for 2.07 +/- 0.48 years. The following events were registered: fatal and nonfatal myocardial infarction (MI), unstable angina (UA), fatal and nonfatal stroke, death of other causes. At ACS onset sinus rhythm was noted in 419 (92.5%), permanent or persistent AF-in 16 (3.5%), attack (paroxysm) of AF - in 18 (4.0%) patients. Mean length of life before end point was 884.9 +/- 23.4, 827.3 +/- 123.3 and 514.0 +/- 111.3 days in patients with sinus rhythm, permanent/persistent AF, and attack of AF during first 10 days of ACS, respectively (p<0.001). Compared with patients in sinus rhythm in patients with attack of AF relative risk (RR) of occurrence of any end point was 1.75 (95% confidence interval [CI] 1.284 to 2.873, p< 0.001), of fatal MI - 1.72 (95% CI 1.026 to 2.873, p=0.040), of UA - 2.116 (95% CI 1.249 to 3.585, p=0.005), of stroke - 2.863 (95% CI 1.300 to 6.301, p=0.009). Multifactorial analysis selected history of MI and attack of AF during first 10 days of ACS as independent predictors of unfavorable outcome. Thus paroxysmal form of AF during hospital stay because of ACS is associated with higher probability of development of unfavorable events in the next 1-2 years.
