This study aimed to determine whether I/D polymorphism predispose to the development of MI in Tunisia. 50 patients with coronary artery disease complicated by MI and 70 healthy controls were analyzed. Quantitative analyses lipids are founded. DNA was isolated from blood samples. Polymorphisms were assessed by polymerase chain reaction method. Statistical differences between groups were determined by Chi-square test. Compared to controls, cases have significantly higher levels of total cholesterol, triglycerides and LDL-cholesterol and lower level of HDL-cholesterol. There are no significant differences between patients and controls in terms of allelic and genotypic frequencies. However, the frequency of the “I” allele is higher in cases which have 2 MI (p=0.0354). Additionally, a statistically significant association between diabetes, arterial high blood pressure, family history and cigarette smoking with MI was founded (p<0.01). I/D polymorphism of t-PA gene is not associated with MI in this sample of Tunisian population.
