摘要/Abstract

摘要： 本次研究目的是探讨超声心动图评价冠心病节段性室壁运动异常价值。选取冠心病节段性室壁运动异常患者89例,均给予超声心动图检查及经皮冠状动脉介入治疗(PCI),术后室间隔、侧壁、前壁、下壁、前间隔各节段心肌收缩期峰值速度(PMSV)、舒张早期峰值速度(PMDV)以及心脏整体面积应变(GAS)、左心室射血分数(LVEF)、收缩末期左心室容血量(LVESV)和舒张末期左心室容血量(LVEDV)较术前明显改善(P<0.05);GAS预测左室功能改善的ROC曲线下面积为0.774(P>0.05)。在冠心病节段性室壁运动异常评价中,超声心动图有较好的应用价值,有助于疾病的检出及治疗疗效的预测。

Abstract: The purpose of this study was to explore the value of echocardiography in the evaluation of segmental wall motion abnormalities in coronary heart disease. 89 patients with coronary heart disease with segmental wall motion abnormality were selected. Echocardiography and percutaneous coronary intervention (PCI) were performed. The peak of myocardial systolic velocity (PMSV) and peak of myocardial diastolic velocity (PMDV) in each segment of interventricular septum, lateral wall, anterior wall, inferior wall and anterior septum after operation, and global area strain of the heart (GAS), left ventricular ejection fraction (LVEF), left ventricular end systolic volume (LVESV) and left ventricular end diastolic volume (LVEDV) were significantly improved compared with those before surgery (P<0.05). The area under the ROC curve for GAS was 0.774 (P>0.05). Echocardiography has a good application value in the clinical pathway evaluation system of coronary heart disease segmental ventricular wall motion abnormality, which is helpful for the detection of disease and the prediction of therapeutic effect.
