%X To explore the influencing factors of survival time of patients with
heart failure, a total of 1789 patients with heart failure were collected from

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), </span><i><span style=\"font-family:Verdana;\">¦Â</span></i><span style=\"font-family:Verdana;\">-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 infection</span></span></span></span><span><span><span style=\"font-family:;\" \"=\"\"> </span></span></span><span><span><span style=\"font-family:;\" \"=\"\"><span style=\"font-family:Verdana;\">and </span><i><span style=\"font-family:Verdana;\">¦Â</span></i><span style=\"font-family:Verdana;\">-blockers.</span></span></span></span>
