Lack of association between factor V Leiden and prothrombin G20210A polymorphisms in Tunisian subjects with a history of myocardial infarction

Background dial infarction is a multifactorial disease. It is provoked by occlusions in the coronary arteries resulting from exposure to multiple risk factors. ive dy the risk of myocardial infarction associated with the gene polymorphisms of factor V Leiden and factor II (G20210A). als and methods consisted of 100 myocardial infarction patients who were hospitalized in the Principal Military Hospital of Tunis and 200 control subjects with no history of myocardial infarction. s evalence of the factor V Leiden was higher in myocardial infarction patients (9%) than in control subjects (6%) with an OR=1.55 (95% CI=0.58–4.12), whereas the prevalence of prothrombin G20210A mutation was 3% and 2.5% in the patient and control groups, respectively [OR=1.21 (95% CI=0.22–5.94)]. sion sults indicate that neither factor V Leiden nor the prothrombin G20210A contributed to the risk factors for myocardial infarction.
