Association of factor V Leiden R506Q , FXIIIVal34Leu , and MTHFR C677T polymorphisms with acute myocardial infarction

Background Acute myocardial infarction (AMI) is a leading cause of death and morbidity around the world. Although the association between thrombophilia and AMI is well-established, controversial data are present on the association between thrombophilic polymorphisms and AMI. The aim of this study was to investigate the association of three thrombophilic polymorphisms including factor V Leiden ( FVL ), MTHFRC677T (methylenetetrahydrofolate reductase), and Coagulation factor XIIIVal34Leu with AMI in East of Iran. Result There were no statistically significant differences between the patients and control groups in terms of the distributions of allelic and genotypic frequencies of FVL and FXIIIVal34Leu polymorphisms ( P -value > 0.05). Subjects who carried CT genotype of MTHFR C677T polymorphism were at a 2.03-fold higher risk for AMI ( P -value: 0.02, OR 1.76, 95% CI 1.07–2.75). Furthermore, patients with MTHFR 677 CT ( P -value < 0.001, β = - 0.90, 95% CI − 1.33, − 047) or 677CC ( P -value < 0.001, β = - 1.04, 95% CI − 1.47, − 0.61) genotypes showed significantly Lower creatinine levels compared with patients having the MTHFR 677TT. No association was observed between the other remaining polymorphisms and AMI ( P -value > 0.05). Conclusion Our findings showed that MTHFRC677T polymorphism could contribute to AMI susceptibility and increase creatinine levels in east Iran population. This was the first study to examine the association of these three polymorphisms with AMI in east Iran.
