最初非相应ST段压低的急性心肌梗塞患者临床特征及预后

目的 :分析最初心电图表现为单纯 ST段压低的急性心肌梗死 (AMI)患者的临床特征及预后。方法 :2 13例AMI患者中表现为 ST段压低者的临床特征及住院并发症 ,行常规 12导联心电图及右胸导联心电图 ,并与无 ST段压低者比较。结果 :AMI伴 ST段压低者 2 3例 (占 10 .8%)。伴 ST段压低组较无 ST段压低组年龄大 (P<0 .0 5 ) ,吸烟者少 (P<0 .0 5 ) ,严重心律失常 (P<0 .0 5 )及泵衰竭 (P<0 .0 5 )发生率高 ,住院病死率明显增高 (P<0 .0 1)。结论 :AMI患者伴有 ST段压低的只占少数 (10 .8%) ,其预后差

Clinical features and prognosis of the initial non-corresponding ST-segment depression in patients with acute myocardial infarction

Objective:To analyze the clinical features and prognosis of simplex ST-segment depression in patients with acute myocardial infarction(AMI).Methods:Two hundred and thirteen patients with AMI were analyzed.The clinical features and in-hospital mortalities of groups of patients with and without ST-segment depression were compared.Results:Among 213 AMI patients,23 patients(10.8 %) were complicated by ST-segment depression.Patients with ST-segment depression were old than patients without ST-segment depression( P <0.05),and had a greater level of myocardial infarction( P <0.05),a litter smoking( P <0.05),a greater incidence of severe arrhythmia( P <0.05) and heart failure( P <0.05) and had a higher in-hospital mortality( P <0.01).Conclusion:Patients with AMI complicated ST-segment depression were the few (10.8 %) and had worse in-hospital prognosis.
