				        	Objective To investigate the predictive value of quantitative flow ratio(QFR)on the occurrence of major adverse cardiovascular events(MACE)3 years after percutaneous coronary intervention(PCI)in patients with non-acute myocardial infarction.Methods This study included 139 patients with non-acute myocardial infarction who underwent PCI from January 2020 to June 2020 in the cardiac catheterization room of our hospital,all of them underwent post-PCI target vessel QFR measurements,and the incidence of MACE was followed up 3 years after PCI.The cut-off value of QFR was calculated by receiver operating characteristic(ROC)curve,according to which patients were divided into QFR>0.95 group and QFR≤0.95 group,and patients were divided into MACE group and non-MACE group depending on whether MACE occurs.The independent influencing factors of post-PCI QFR in patients with non-acute myocardial infarction were investigated by univariate and multifactorial linear regression analysis.Univariate and multivariate Cox regression analysis was used to investigate the predictive value of post-PCI QFR in the occurrence of MACE 3 years after PCI in patients with non-acute myocardial infarction.The long-term prognosis of patients with QFR>0.95 and those with QFR≤0.95 was compared by drawing the survival curve of no-MACE event.Results ROC curve analysis showed that post-PCI QFR predicted the occurrence of MACE 3 years after surgery in non-acute myocardial infarction patients with statistical significance(AUC 0.666,95%CI 0.556-0.777,P=0.003),and the cut-off value of MACE was 0.95.The sensitivity and specificity were 75.00%and 51.30%for the diagnosis of MACE with QFR≤0.95.Patients were divided into QFR≤0.95 group(n=74)and QFR>0.95 group(n=65)according to the cut-off value.Multivariate linear regression analysis showed that the maximum area stenosis rate after PCI was an independent factor for post-PCI QFR(P<0.001).Multivariate Cox regression analysis showed that body mass index(BMI),post-PCI QFR,three-vessel lesions and post-PCI QFR groups were independent influencing factors of no-MACE lifetime.The no-MACE survival curve showed that the long-term prognosis of patients in the QFR>0.95 group was significantly better than that in the QFR≤0.95 group(x2=5.272,P=0.022).Conclusions The optimal cut-off value of post-PCI QFR for predicting the occurrence of MACE 3 years after PCI in non-acute myocardial infarction patients was 0.95,and patients with QFR≤0.95 had worse long-term prognosis,and BMI,three-vessel lesions,and post-PCI QFR≤0.95 were independent risk factors for the occurrence of MACE 3 years in non-acute myocardial infarction patients after PCI.
