Heart failure (HF) is associated with perturbations of the interleukin-6 (IL-6) signaling pathway. A total of 559 Danish subjects with severe chronic HF enrolled in the previously reported Echocardiography and Heart Outcome Study were genotyped for three SNPs in IL6, nine in the IL-6 receptor gene (IL6R), and two in the IL-6 signal transducer gene (IL6ST). After a mean follow-up of 5.0 years, 5 SNPs in IL6R introns (rs12083537, rs6684439, rs4845622, rs4537545, and rs7529229) and a SNP in the IL6R coding region (rs2228145, also known as Asp358Ala) were associated with adverse outcomes, e.g., hazard ratios (HRs) for cardiovascular death and all-cause death 1.38 (CI: 1.09-1.76; P = 0.008) and 1.37 (CI: 1.10-1.70; P = 0.004) for rs6684439 heterozygotes, and 1.39 (CI: 1.09-1.77; P = 0.007) and 1.37 (CI: 1.10-1.70; P = 0.005) for rs4845622 heterozygotes, respectively. We conclude that SNPs in the IL-6 signaling pathway may be independent predictors of fatal outcomes in patients with severe HF.
