In the multivariate Cox proportional hazards analysis, the low DBP group was an independent predictor of HF readmission after adjustment for age, sex, SBP, hemoglobin, serum albumin, serum creatinine, BNP, RASi, CCB, LVEF, CAD, and whether they live alone (hazard ratio 2.229; 95% confidence interval 1.021–4.867; p = 0.044) (Table 3). The gene discussed is MMP19; the disease is coronary artery disorder.
