摘要

Background Frailty is a multidimensional syndrome that reflects the physiological reserve of elderly.It is related to unfavorable outcomes in various cardiovascular conditions.We conducted a systematic review and meta-analysis of the association of frailty with all-cause mortality and bleeding after acute myocardial infarction (AMI) in the elderly.Methods We comprehensively searched the databases of MEDLINE and EMBASE from inception to March 2019.The studies that reported mortality and bleeding in AMI patients who were evaluated and classified by frailty status were included.Data from each study were combined using the random-effects,generic inverse variance method of DerSimonian and Laird to calculate hazard ratio (HR),and 95％ confidence interval (CI).Results Twenty-one studies from 2011 to 2019 were included in this meta-analysis involving 143,301 subjects (mean age 75.33-year-old,60.0％ male).Frailty status was evaluated using different methods such as Fried Frailty Index.Frailty was statistically associated with increased early mortality in nine studies (pooled HR =2.07,95％ CI: 1.67-2.56,P ＜ 0.001,I2=41.2％) and late mortality in 11 studies (pooled HR =2.30,95％ CI: 1.70-3.11,P ＜ 0.001,I2=65.8％).Moreover,frailty was also statistically associated with higher bleeding in 7 studies (pooled HR =1.34,95％ CI: 1.12-1.59,P ＜ 0.001,I2 =4.7％).Conclusion Frailty is strongly and independently associated with bleeding,early and late mortality in elderly with AMI.Frailty assessment should be considered as an additional risk factor and used to guide toward personalized treatment strategies.
