Background: Recent research has supported the central role of coagulative factors in advancing atherosclerosis and causing coronary artery disease (CAD single-vessel, two-vessel, and three-vessel diseases was 72.8%, 71.5%, and 76.4%, respectively; the difference was also insignificant (p = 0.379). 43.39 ± 46.18 in the patients with QQ genotype, 38.87 ± 42.89 in those with QR genotype, and 55.61 ± 53.80 (Cardiol J 2013; 20, 5: 533-538) No relationship was observed between the distribution of the genotypes and the number of the involved coronary vessels. The average of the Gensini score was
