Abstrakt: Objective: To examine the contribution of six cardiovascular polymorphisms to the occurrence of a first event of ischemic heart disease (IHD) in a primary care population with a high prevalence of hypertension. Furthermore, we specified the data for sex and age.
Methods: In this cross sectional case-control study, patients with a first event of IHD (157) and event-free controls (571) were studied. Both the groups were genotyped for the angiotensin II type 1 receptor (A1166C), angiotensinogen (M235 T), angiotensin converting enzyme (4656rpt), endothelial nitric oxide synthase (E298D), G-protein beta3 subunit (C825 T), and alpha-adducin (G460W) polymorphisms. Univariate and multivariate odds ratios (ORs) were calculated to assess the association between a first ischemic event and these polymorphisms. Sliding mean analyses were performed to show age-specific associations.
Results: Multivariate ORs indicated a protective association for the carrier status of the T-allele of AGT, overall [OR = 0.69 (0.34-0.90)] and for males [OR = 0.58 (0.27-0.89)]. Sliding mean analyses showed a continuous protective association with IHD of the T-allele of AGT with increasing age in males, whereas in females an increased risk for IHD was observed with a maximum OR of 1.6 at the age of 56 years.
Conclusion: In this population the T-allele of the AGT polymorphism is protective for a first event of IHD in males.
