Many epidemiological studies have reported an association between hemostatic factors and risk of both coronary and peripheral artery diseases. Using polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) analysis, we investigated the association between coronary artery disease and polymorphisms in the methylenetetrahydrofolate reductase ( MTHFR C677T and A1298C), prothrombin (G20210A), and factor V (A4070G) genes. We screened these gene variants in 174 subjects who had undergone coronary angiography - 115 patients with patent coronary artery disease (grade 3 vessel disease, i.e. , significant coronary stenosis), and 59 healthy controls with grade 0 vessel disease. The analysis of our data did not show any statistically significant association between coronary artery disease (CAD) and the investigated polymorphisms.
