The predictive value of epinephrine for MACE in patients with STEMI after emergency PCI
Objective To explore the predictive value of Epinephrine(EPI)level for Major adverse cardiovascular events(MACE)in patients with ST segment elevation myocardial infarction(STEMI)after emergency Percutaneous coronary intervention(PCI).Methods A total of 107 patients with STEMI after emergency PCI in Northern Jiangsu People's Hospital of Jiangsu Province from September 2020 to November 2021 were selected.Baseline data,biochemical test data and coronary angiography data were collected.EPI level was measured by enzyme-linked immunosorbent assay.The following analysis was planned:① Patients were divided into MACE group and non-MACE group,and various indicators of the two groups were compared;② According to Receiver operating characteristic curve(ROC),the best cut-off values of EPI level which predict the occurrence of MACE were calculated respectively.Patients were respectively divided into high EPI level group and low EPI level group according to the best cut-off values,and the occurrence of MACE between the groups was compared respectively.③ Survival analysis(Kaplan-Meier method and log-rank test)was used to investigate the relationship between EPI level and MACE in patients with STEMI after emergency PCI.④ COX proportional hazard regression model was used to investigate the risk factors for MACE in patients with STEMI after emergency PCI.Results ① According to the inclusion and exclusion criteria,107 patients with STEMI after emergency PCI were selected for the study,of which 19 patients had MACE and 88 patients did not have MACE.Compared with the non-MACE group,the patients in the MACE group were older,the proportion of Killip Ⅱ and above,NT-proBNP and EPI were higher,while FT3 was lower,and the differences were statistically significant(P＜0.05).The Gensini score of MACE group was significantly higher than that of non-MACE group(P＜0.01).② According to ROC analysis,the Area under the curve(AUC)of EPI level for predicting MACE in patients with STEMI after emergency PCI was 0.699(95％CI:0.579-0.819,P=0.007),the best cut-off value of EPI level was 528.54,the sensitivity was 78.9％,and the specificity was 56.8％.The incidence of MACE in the high EPI level group was significantly higher than that in the low EPI group(P=0.005).③ Kaplan-Meier survival curve showed that the higher the EPI level value,the higher the risk of MACE(log-rank test P=0.004).④ Multivariate COX regression analysis showed that age(P=0.042),FT3(P＜0.001),EPI level(P＜0.001)and Gensini score(P=0.004)were independent risk factors for MACE.Conclusions ① EPI level significantly correlates with the occurrence of MACE in patients with STEMI after emergency PCI.EPI level has predictive value for MACE in patients with STEMI after emergency PCI.The higher the EPI value,the higher the risk of MACE.② Multivariate COX regression analysis show that EPI level is independent risk factor for MACE in patients with STEMI after emergency PCI.
