PPARy2 Gene Alleles Expression in Elderly Patients with Obesity and Coronary Artery Disease

We have explored the features of PPARγ2 gene alleles expression in elderly patients with comorbid conditions such as obesity and coronary artery disease. 140 patients of both sexes (54.3% men and 45.7% women) aged 60-89 were examined. The main group included 70 pts with CHD; the control group included 70 pts without CHD. Pro12 allele carrier state in the main group was 85%, and Ala12 allele carrier state – 15%. Pro12Ala and Ala12Ala genotypes, Ala12 allele were detected more often in patients with coronary artery disease than in the control group (p = 0.0008 and p = 0.0003, respectively). Pro12Ala genotypes (OR = 2.02, CI = 1.28–3.19, p = 0.003) and Ala12Ala (OR = 2.002, CI = 1.32–3.04, p = 0.0006) of Ala12 gene PPARγ2 carrier state increases the risk of CHD developing by 2 times. It was confirmed that nuclear PPARs are capable of controlling development, differentiation, metabolic homeostasis and reproduction. The role of various genotypes of the PPARγ2 gene in the regulation of lipid metabolism and angiogenesis in comorbid conditions in elderly patients may help to identify new methods of their treatment.
