Abstract

Single point mutations in the genes coding for hemostatic factors were shown to be major inherited predisposing factors for venous thromboembolism. However, their contribution in the development of non-diabetic coronary artery disease [nDCAD] remains controversial. Angiographically demonstrated nDCAD patients (n = 86) and healthy controls (n = 90) were included in the study. Genotype analysis of hemostatic gene polymorphisms were assessed by using CVD strip assay, based on allele specific oligonucleotide probes. The carrier frequency of factor V (FV) H1299R, prothrombin G20210A, glycoprotein (Gp) IIIa L33P, plasminogen activator inhibitor-I (PAI-1) 4G/5G, 4G/4G, 5G/5G, methylenetetrahydrofolate reductase (MTHFR) A1298C and β-fibrinogen -455 G > A were similar between patients and controls. In contrast, frequency of FV Leiden was significantly higher among patients (12.5%) than controls (5%, OR: 7.94; 95%CI: 1.9-49.6) and FXIII V34L was significantly lower among patients (23.7%) than controls (40%, OR: 0.24; 95%CI: 0.1-0.89). In addition, the frequency of the MTHFR C677T polymorphism was 32.5% among patients compared with 42.5% in controls, of which the T/T genotype was significantly lower among patients (5%) than controls (17.5%, OR: 0.06; 95%CI: 0.01-0.58). No difference was observed in prevalence of prothrombin G20210A, FV H1299R, Gp IIIa L33P, PAI-1 4G5G, MTHFR A1298C, β fibrinogen 455 G > A mutations between patients and controls. However, lower frequency of FXIII Val34Leu and MTHFR C677T polymorphisms may decrease, while FV Leiden polymorphism may increase development of nDCAD. © 2009 Springer Science+Business Media B.V.
