心电图 ST段压低和无偏移型心肌梗死患者的临床特征
Clinical features in patients with ST depression and non-ST segment devi-ation myocardial infarction
摘要
Abstract
Aim:To explore the clinical features in patients with non-ST-elevation myocardial infarction ( NSTEMI) and different electrocardiographic manifestations .Methods:A total of 203 consecutive patients with NSTEMI undergone early coronary angiography .According to the difference of ST segment deviation pattern ,the patients were divided into two groups:ST-depression group(121 cases)and non-ST-deviation group(82 cases).The clinical characteristics,the lesion features of coronary artery,the mortality in hospital,infarction related artery(IRA)and its TIMI grades prior and after interventional therapy were analyzed.Results:(1)The young and male patients were less common for myocardial infarction and diabetes in non-ST-deviation group.(2)There were more single-vessel lesion in non-ST-deviation group(χ2 =14.868,P=0.002), and the IRA was often the circumflex artery .The rate of total occlusion of IRA in non-ST-deviation group was lower than that in ST-depression group(χ2 =37.516,P<0.001).Collateral circulation in non-ST-deviation group was better than that in ST-depression group(χ2 =12.500,P<0.001).(3)It was more frequent in ST-depression group without primary percutane-ous coronary intervention than non-ST-deviation group(χ2 =18.160,P<0.001).The rates of death between the two groups had no significant differences (χ2 =1.810,P=0.178).Conclusion:There are obvious differences between ST-depression and non-ST-deviation groups in clinical characteristics ,the lesion features of coronary artery ,therapy strategy and the mortal-ity in hospital .NSTEMI patients with different ECG manifestations should be treated with PCI in time .关键词
