摘要目的　探讨不稳定型心绞痛 (UA)患者心电图T波变化的临床意义。方法　分析2 0 3例冠状动脉造影阳性的UA患者 ,其心电图T波、ST段有异常改变 ,并分析其与临床危险分层及冠状动脉病变的关系。结果　心电图出现T波异常≥ 2个导联者 173例 ( 85 .2 %) ,而T波异常≥ 6个导联在多支病变组为 73 .9%,显著高于单支病变组 2 0 .5 %;显著T波倒置在UA高危组为65 .9%,明显多于低中危组 8.3 %;T波异常伴ST段压低在UA高危组为 80 .8%,明显多于低中危组 10 .2 %。T波异常的导联数同冠状动脉病变程度有明显相关性 (r =0 .874,P <0 .0 1)。 Objective To evaluate the clinical significance of T waves in unstable angina(UA).Methods T waves abnormality and ST segment depression in ECG were analysed in 203 UA patients with positive coronary angiography and were compared with coronary artery angiography and UA risk stratification.Results T waves abnormality ≥2 leades appeared in 173 (85.2%) patients,but T waves abnormality ≥6 leades were higher in multi vessel disease (73.9%) than in single vessel disease (20.7%) and obvious T waves inversion or ST segment depression with T waves abnormality were higher in high risk group (65.9%,80.8%) than in low or intermediate risk group (8.3%,10.2%).The total leades of T waves abnormality have a good relativity with coronary artery vessel disease( r =0.874, P <0.01).Conclusion Quantitative analysis of T wave abnormality will be useful to provide optimal risk stratification in UA patients.
