Prevalence of myocardial infarction polymorphisms in Afyonkarahisar, Western Turkey

Abstract

The aim of the study was to investigate relationship between polymorphisms in genes that are clinical and environmental features and the risk of myocardial infarction (MI) in Afyonkarahisar subjects living in Turkey. Prevalence of the several genes polymorphisms, ≤45 (42.04 ± 3.3) and ≥46 (57.19 ± 7.5) years were studied in individuals with MI and without MI (40.30 ± 9.01) individuals were studied. We tested 140 with MI individuals for factor V (FV) Leiden, FV H1299R, Prothrombin G20210A, factor XIII (FXIII) V34L, β-fibrinogen b-455G/A, plasminogen activator inhibitor-1 (PAI-1)-675 4G/5G, human platelet antigens 1 (HPA-1) a/b, apolipoprotein B (ApoB) R3500Q, apolipoprotein E (ApoE), E2, E3, and E4, angiotensin-converting enzyme (ACE) D/I, 5,10 methylenetetrahydrofolate reductase (MTHFR) 677C/T, and MTHFR 1298A/C polymorphisms using a ViennaLab CVD strip assay. This study results were compared without MI control groups. According to the our results, prothrombin, factor XIII and MTHFRC677T deletions were the most frequent genetic variants in risk groups of hyperlipidemic patients (value of odds ratio sequentially [OR] = 4.5, p = 0.05, [OR] = 2.16, p = 0.04 and [OR] = 2.8, p = 0.09). MTHFRA1298C and PAI-1 deletions were most frequent genetic variants in risk groups for MI in patients with diabetes mellitus (value of odds ratio sequentially [OR] = 3.79, p = 0.06 and [OR] = 5 × 10(8), p = 0.000). ACE deletions were positively associated with family history of cardiovascular events (OR = 3.62, p = 0.03). We found a strong relationship between genetic variants and risk factors. Significant associations between genetic variants predicting cardiovascular events and common risk factors (hyperlipidemia, smoking, diabetes mellitus and family history) patients were found.
