Background:Diabetes mellitus(DM)is an important risk factor in the long-term outcomes of surgical revascularization.However,few studies have focused on patients with ischemic heart failure(IHF)and DM,and the results are controversial.This study aimed to evaluate the effect of DM on the long-term outcomes of IHF patients undergoing coronary artery bypass grafting(CABG).Methods:In this propensity-matched study,data of IHF patients who underwent CABG in our hospital from January 2007 to December 2017 were analyzed.With a mean 73-month follow-up time,the patients were divided into two groups according to whether they had DM.The primary endpoint was all-cause death,and the secondary endpoint was a composite of all-cause death,stroke,recurrent myocardial infarction,and revascularization.Results:There was no significant difference in all-cause mortality between the two groups(5.8%vs.4.1%,P=0.216).The incidence of main adverse cardiovascular and cerebrovascular events(MACCE)in the secondary endpoint was significantly higher in the DM group than that in the non-DM group(10.4%vs.8.1%,P=0.023).Conclusions:DM can negatively affect the long-term outcomes of IHF patients undergoing CABG by significantly increasing the overall incidence of MACCE,though the long-term survival does not show a significant difference between the DM and non-DM patients.
