【摘要】：目的探讨三维斑点追踪技术(3D-STE)结合腺苷负荷试验诊断早期冠心病(缺血心肌节段)的临床价值。方法在2015年7月—2016年9月于广东省第二人民医院心血管内科住院的疑似冠心病患者中采用随机数字表法抽取61例,常规超声心动图未见室壁运动异常,根据冠状动脉造影结果分为冠心病组(45例)与对照组(16例),其中冠心病组又分为缺血心肌节段亚组和非缺血心肌节段亚组。应用3D-STE结合腺苷负荷试验检测左心室各血管节段径向、纵向、环向收缩期峰值应变(RS、LS、CS)及面积收缩期峰值应变(AS)。绘制RS、LS、CS、AS诊断缺血心肌节段的受试者工作特征曲线(ROC曲线),分析其诊断价值。结果缺血心肌节段亚组与非缺血心肌节段亚组、对照组RS、LS、CS、AS比较,差异均有统计学意义(P0.05),而对照组与非缺血心肌节段亚组间差异均无统计学意义(P0.05)。RS、LS、CS、AS诊断缺血心肌节段的ROC曲线下面积分别为0.868、0.916、0.786、0.921。结论 3D-STE结合腺苷负荷试验可定量评价心肌收缩功能的微小改变,AS能较好地识别心肌缺血,对诊断早期冠心病具有很高的临床价值。
[Abstract]:Objective to evaluate the clinical value of 3D-STE combined with adenosine stress test in the diagnosis of early coronary heart disease (ischemic myocardial segment). Methods from July 2015 to September 2016, we were hospitalized in the Department of Cardiovascular Medicine, the second people's Hospital of Guangdong Province. Sixty-one patients with suspected coronary heart disease were selected by random digital table. No abnormal wall motion was found in routine echocardiography. According to the results of coronary angiography, they were divided into coronary heart disease group (n = 45) and control group (n = 16). Coronary heart disease group was divided into ischemic myocardial segment subgroup and non-ischemic myocardial segment subgroup. Left ventricle was detected by 3D-STE combined with adenosine stress test. Radial segments of blood vessels, Longitudinal, ROC curve was drawn for the diagnosis of ischemic myocardial segment. Results Ischemic myocardial segment subgroup and non-ischemic myocardial segment subgroup were divided into two groups. The control group was compared with the control group, and the control group was compared with the control group. There was no significant difference between the control group and the non-ischemic myocardial segment subgroup. The area under the ROC curve for diagnosis of ischemic myocardial segment was 0.868 ~ 0.916 ~ 0.786 ~ 0.921 respectively. Conclusion 3D-STE combined with adenosine stress test can be quantitatively evaluated. Small changes in myocardial contractile function can be used to identify myocardial ischemia. It has high clinical value in the diagnosis of early coronary heart disease.
