The aim: To examine the association between polymorphisms of the IL-6 gene promoter and HF in patients with CAD and obesity. Material and methods: 222 patients with coronary artery disease and obesity were identified. Comparison group consisted of 115 patients with coronary artery disease with normal body weight. The groups were comparable in age and sex. The exclusion group consisted of patients with severe concomitant diseases of the respiratory and digestive organs, kidneys and people with cancer. One single nucleotide polymorphisms in the interleukin-6 promoter region was analyzed. Odds ratio (OR) and 95 % confident interval (95 % CI) were calculated. Results: The combined course of coronary artery disease and obesity was characterized by the detection of allele C in 62 patients (27.93 %), allele G - in 160 patients (72.07 %), and genotypes CC, CG and GG - at 24 (10.81 %), 67 (30.18 %) and 131 (59.01 %) patients respectively. The results showed that the -174G allele and GG genotype in patients with coronary artery disease and obesity were associated with heart failure (OR = 2.55, 95% CI = [1.72-3.79], χ2 = 22.8; p<0.05) and (OR = 11.95, 95% CI = [3.41-41.91], χ2 = 22.5; p<0.05), whereas allele C-174 was associated with a decrease in the risk of heart failure (OR = 0.39, 95% CI = [0.26-0.58 ], χ2 = 22.75, p<0.05). Conclusions: The obtained results testify that the -174G>C polymorphism in the interleukin-6 gene is significantly associated with increased risk of heart failure in patients with coronary artery disease and obesity.
