Abstract:
Objective To evaluate the predictive value of pyruvate kinase M2(PKM2)and transferrin saturation(TSAT)for major adverse cardiovascular events(MACE)in chronic obstructive pulmonary disease(COPD)-coronary artery disease(CAD)patients after percutaneous coronary intervention(PCI),and to analyze the relationship between these indicators and patients'cardiac function status.Methods The study cohort included 94 COPD-CAD patients diagnosed in Zhuozhou Hospital from January 2020 to May 2022.Left ventricular end-diastolic volume(LVEDV),left ventricular end-systolic volume(LVSV),left ventricular ejection fraction(LVEF),mitral valve inflow velocity(E)and early diastolic mitral annular velocity(e')were assessed by echocardiography.Plasma PKM2 and TSAT levels were analyzed using enzyme-linked immunosorbent assay kit.All patients were followed up for 2 years.The study end point was defined as MACE.Results During follow-up,22 patients(23.4%)experienced MACE.Compared with the non-MACE group,the MACE group showed increased peripheral blood PKM2 levels(P<0.05)and decreased TSAT levels(P<0.05).PKM2 was positively correlated with left ventricular end-systolic volume and E/e'(r=0.204 and 0.209,both P<0.05),and negatively correlated with ejection fraction and TSAT(r=-0.430 and-0.641,both P<0.001).TSAT was negatively correlated with left ventricular end-diastolic volume,left ventricular end-systolic volume and E/e'(r=-0.309,-0.470,-0.411,all P<0.001),and positively correlated with ejection fraction(r=0.470,P<0.001).PKM2(Hr=9.375,95%CI=4.145～21.203)and TSAT(Hr=0.753,95%CI=0.645～0.878)were independent influencing factors of MACE events in COPD-CAD patients(P<0.05).The AUC of PKM2 and TSAT in predicting MACE events were 0.835(95%CI=0.729～0.940)and 0.878(95%CI=0.811～0.946),respectively,with specificity of 72.7%and 90.9%,and sensitivity of 87.5%and 80.6%,respectively.Conclusion In patients with COPD-CAD treated by PCI,the changes of PKM2 and TSAT levels are independently related to MACE events,and are helpful to predict the occurrence of MACE events.
