The aim of this study was to clarify the relationship between factor V Leiden and prothrombin G20210A with acute MI in patients younger than 50 years of age. Materials and methods: In this case-control study we recruited 101 MI patients and 101 healthy individuals in Fatemeh Zahra Hospital, affiliated to Mazandaran University of Medical Sciences. Demographic information and risk factors including age, past history of MI, diabetes mellitus, hypertension, dyslipidemia, and smoking were recorded. Genes of factor V Leiden and prothrombin G20210A were analyzed using PCRRFLP method. Results: Among all subjects, 191 (94.55%) had no factor V Leiden gene, 10 (4.95 %) were heterozygous, and one (0.49%) was homozygous. In case group, and control group there were seven (6.9%) and three (2.97%) heterozygous for factor V Leiden, respectively (P= 0.27). There was no mutation of prothrombin G20210A gene in 197 (97.5%) individuals and only five (2.5%) were heterozygous. There was no statistically significant difference between the two groups (P= 0.17). Conclusion: The prevalence of factor V Leiden and prothrombin G20210A gene mutation, in patients was not significantly different from that of the normal individuals. However, further studies are recommended in this age group to investigate these factors.
