OBJECTIVES Coronary artery ectasia (CAE) is defined as localized or diffuse dilatation of the coronary artery lumen exceeding the diameter of adjacent healthy reference segments by 1.5 times. The etiology of coronary artery ectasia is still unknown, but the most likely cause is atherosclerosis. In this study, we aimed to evaluate some gene polymorphisms that are thought to be effective in the development of coronary atherosclerosis and have been shown to cause thrombophilia in CEA patients.
METHODS In our study Factor V Leiden (G1691A), Factor V H1299R, Prothrombin G20210A, Factor XIII V34L, B-Fibrinogen -455 G>A, PAI-1 4G/5G, MTHFR C677T, and MTHFR A1298C polymorphisms were evaluated in 66 patients with CAE and 32 individuals with normal coronary artery group.
RESULTS Comparison of the CAE and control groups revealed that clinical features and the frequency of polymorphism in thrombophilic genes (Factor V Leiden (G1691A Factor V H1299R, Prothrombin G20210A, Factor XIII V34L, Beta-Fibrinojen -455 G>A, PAI-1 4G/5G, MTHFR C677T and MTHFR A1298C) were similar in both groups. However, when the groups whether heterozygous and / or homozygous polymorphism were compared, it was found that the CAE group had significantly higher thrombophilic genes polymorphism (p: 0.023).
CONCLUSION Thrombophilic gene polymorphism may be associated to formation and clinical presentation in CAE.
