Abstract: Abstract］ ObjectiveTo investigate the relationship between prognosis and systolic blood pressure(SBP) of elder patients with heart failure. MethodsClinical datas of 35 patients with heart failure from Nov.2009 to Nov.2014 were retrospectively nanlyzed. According to the mean systolic blood pressure， 34(1 patient lost) patients were divided into group A(SBP<100 mmHg), group B(SBP 100-140 mmHg), group C(SBP>140 mmHg). The clinical statistics such as the survive time， BNP， cardiac troponin(cTn) and especially the 24 hour ambulatory blood pressure statistics of the patiens died were collected in two years. ResultsSurvival rate of elderly patients among different SBP showed significant difference(P<0.05); Three groups of elderly patients within 2 years after hospital discharge showed difference between time and the point of interaction(P＞005) but no differences between groups. CTn positive rate was statistically significant difference among the 3 groups(P＜005). The cTn positive rate in group A and the group C were higher than those in group C at 3 months. The cTn positive rate in group A were higher than those in group B and the group C at 6 months. The cTn positive rate in group A were higher than those in group B and the group C at 1to 2 years, and group A were higher than those in group B(P＜005). Within 2 years of followup, 25 patients (death) in the event group and 9 patients (survival) in the non event group had significant difference in the dynamic SBP level 24 h before discharged from hospital(P＜005). The event group had lower dynamic SBP than the survival group(P＜005). ConclusionSBP can be used as an index to judge the prognosis of elderly patients discharged from hospital. Clinicians should take effective measures for patients with SBP with lower heart failure.
