Multivariate analysis of 1-year mortality revealed that diabetes (OR 7.031, 95% CI 2.193–22.542, p = 0.001), atrial fibrillation (OR 8.217, 95% CI 1.932–34.943, p = 0.004), laboratory data lymphocyte count (OR 0.041, 95% CI 0.007–0.252, p < 0.001), red blood cell count (OR 0.167, 95% CI 0.056–0.492, p = 0.001), IL-6 level (OR 1.012, 95% CI 1.004–1.020, p = 0.003) and LDH level (OR 1.005, 95% CI 1.002–1.009, p < 0.001) were predictive of mortality. The gene discussed is IL6; the disease is diabetes mellitus.
