组织多普勒Tei指数与冠状动脉病变程度的关系

目的评价组织多普勒Tei指数(DTI-Tei指数)与冠状动脉病变严重程度的关系。方法将126例行冠状动脉造影或介入治疗的非心肌梗死患者分为冠心病组与非冠心病组,根据Gensini评分分为无病变组、轻度病变组、严重病变组,应用组织多普勒(DTI)测定所有患者的Tei指数,观察DTI-Tei指数与冠状动脉病变Gensini评分的相关性及对严重冠状动脉病变的预测价值。结果冠心病组与非冠心病组相比较DTI-Tei指数差异具有统计学意义(分别是0.41±0.06和0.46±0.09,P<0.01),比较无病变组、轻度病变组、严重病变组的SBP[(135±18)mmHg、(148±19)mmHg和(156±20)mmHg、PP[(58±12)mmHg、(68±13)mmHg和(75±17)mmHg]、HDL-C[(1.29±0.21)mmol/L、(1.25±0.31)mmol/L和(1.11±0.32)mmol/L]、DTI-Tei值(0.41±0.06、0.43±0.07和0.51±0.07)差异有统计学意义(P<0.05),观察SBP、PP值,严重病变组及轻度病变组高于无病变组(P<0.05),严重病变组与轻度病变...

Relationship of Doppler tissue imaging Tei index and extent of coronary atherosclerosis lesions

Objective To estimate the correlation of DTI-Tei index and the severity of coronary atherosclerosis lesions. Methods 126 patients who had taken the coronary angiography or percutaneous coronary intervention were recruited. These non-cardiac muscle infarct patients were divided into coronary artery disease group and non-coronary artery disease group according coronary angiography,and divided into normal,mild lesion group and severe lesion group according Gensini score. All the patients were checked for Tei i...
