The Clinical Efficacy And Prognosis For Patients Of Acute Myocardial Infarction Complicated With Multivessel Disease

BackgroundGuidelines at home and abroad only give clear guidance for the opening of infarct related artery during emergency operation at present,controversy over the strategy of revascularization with the acute myocardial infarction(AMI)patients with multiple vessel disease(MVD)after emergency percutaneous coronary intervention(PCI).ObjectiveTo investigat the clinical efficacy and prognosise of different revascularization(complete or incomplete)about the acute myocardial infarction(AMI)patients with multiple vessel disease(MVD)after emergency percutaneous coronary intervention(PCI).MethodsA retrospective analysis of 200 cases of AMI patients with MVD,according to coronary revascularization divided into complete revascularization group(CR group)82 cases;among them the complete revascularization group(CR1 group)31 cases,elective complete revascularization group(CR2 group)51 cases;Incomplete revascularization group(IR group)118 cases.The baseline clinical characteristics of the two groups,PCI treatment,drug use,clinical curative effect and long-term prognosis of PCI postoperative were recorded.ResultsThere was no significantly different between two groups of patients with baseline clinical characteristics,general drug use,coronary artery disease situation.CR groups of nitrates were significantly lower than IR group,the number of stent placement in CR group was significantly higher than IR group(P<0.05);The recurrent angina,revascularization rate and major adverse cardiovascular events(MACE)of IR group during hospitalization and posthospital were significantly higher than that in CR group,the recurrent angina pectoris and the incidence of MACE of CR2 group were significantly higher than that in CR1 group(P<0.05);Cox proportional hazards regression analysis found that incomplete revascularization is an independent predictors of MACE(P<0.01).ConclusionThe clinical curative effect and prognosis in patients of AMI and MVD achieve complete revascularization is superior to incomplete revascularization by percutaneous coronary intervention;direct complete revascularization was better than the delayed time of complete revascularization;incomplete revascularization is an independent predictor of MACE.
