We investigated apolipoprotein E (APOE) genotypic influence on myocardial infarction risk in South India, where the disease is emerging as a major threat to the public health care system. The study included 412 subjects: 202 myocardial infarction patients and 210 age- and sex-matched controls. DNA was isolated, the polymorphism of the APOE gene was subjected to PCR, and lipid levels were evaluated. The prevalence of E3/E4 genotypes in patients (18.3%) was 1.5-fold that of controls (11.0%, p < 0.05), and the prevalence of E2/E3 genotypes was higher in controls (6.7%) than in patients (4%). The epsilon 4 allele was significantly associated with myocardial infarction: chi (2) = 12.4; OR 2.2 (CI 95%: 1.4-3.4), p < 0.004, for epsilon 4 versus epsilon 3 and chi (2) = 5.7; OR 2.7 (CI 95%: 1.1-6.5), p > 0.01, for epsilon 4 versus epsilon 2. A significant association of the epsilon 4 allele, especially the E3/E4 genotype, with myocardial infarction was observed.
