| Objective:To analyze the acute coronary syndrome with ST-segment elevation in lead a VR,explore the characteristics of coronary lesions,analyze the risk factors of major adverse cardiovascular events,and explore the predictive value of its poor prognosis.Methods:The subjects of the study were patients who were admitted to the Department of Cardiovascular Medicine,Guizhou Provincial People’s Hospital from January 2016 to December 2019,were diagnosed with acute coronary syndrome,had complete clinical data,and had completed electrocardiogram and coronary angiography.Whether there is ST segment elevation in lead a VR is divided into two groups: STEa VR group,that is,the ST segment elevation in lead a VR is ≥0.05 m V;NSTE-a VR group,that is,there is no ST segment elevation or ST segment elevation in lead a VR.High amplitude <0.05 m V.The differences in general clinical data and coronary artery disease characteristics were compared between the two groups.Logistic regression analysis was used to predict the association between a VR and major adverse cardiovascular events.Results: 1.The c Tn I and BNP in the STE-a VR group were higher than those in the NSTE-a VR group(P<0.05);2.The NSTEMI diagnosis rate in the STE-a VR group was higher than that in the NSTE-a VR group(P<0.05);3.STE-a VR The incidence of coronary multi-vessel,left main and proximal left anterior descending artery lesions in the STE-a VR group was higher than that in the NSTE-a VR group(P<0.05);4.The incidence of subtotal coronary occlusion in the STE-a VR group was higher than that in the NSTE-a VR group(P<0.05);5.The incidence of major adverse cardiovascular events in the STE-a VR group was higher than that in the NSTE-a VR group(15.84%:7.89%,P=0.008),and logistic regression analysis showed that STE-a VR(OR=2.418,95%CI 1.173-4.987,P=0.017)was an independent risk factor for major adverse cardiovascular events.Conclusion:.In acute coronary syndromes,STE-a VR has important clinical significance for the diagnosis of NSTEMI,coronary multi-branch lesions,left main trunk,proximal left anterior descending branch,and subtotal coronary occlusion,and STE-a VR is an independent risk factor for the occurrence of major adverse cardiovascular events,indicating a poor prognosis. |
