To explore the influencing factors of survival time of patients with
heart failure, a total of 1789 patients with heart failure were collected from
Shanghai ShuguangHospital. The Cox proportional hazards model and the mixed effects Cox
model wereused to analyze the factors on survival time of patients. The results of Cox
proportional hazards model showed that age (RR = 1.32), hypertension (RR =
0.67), ARB (RR = 0.55), diuretic (RR = 1.48) and antiplatelet (RR = 0.53) have
significant impacts on the survival time of patients. The results of mixed
effects Cox model showed that age (RR = 1.16), hypertension (RR = 0.61), lung
infection (RR = 1.43), ARB (RR = 0.64), β-blockers
(RR = 0.77) and antiplatelet (RR = 0.69) have a significant impact on the survival
time of patients. The results are consistent with the covariates age, hypertension,
ARB and antiplatelet but inconsistent with the covariates lung infectionand β-blockers.
