摘要
目的：探究实时三维超声心动图对冠状动脉病变的临床评估价值。方法选择2013年10月至2014年10月本院径冠状动脉造影确诊的冠心病患者60例为研究对象，根据病变累及范围分为单支组与多支组，每组各30例。根据狭窄程度将单支组患者分为A组（冠状动脉狭窄程度＜50%）及B组（冠状动脉狭窄程度50%～75%），每组各15例；多支组患者分为C组（冠状动脉狭窄程度＜50%）与D组（冠状动脉狭窄程度50%～75%），每组各15例，比较单支组、多支组患者左心室参数及两组中不同冠状动脉狭窄程度患者左心室参数。结果多支组患者左心室舒张末容积（LVEDV）、左心室收缩末容积（LVESV）均明显大于单支组，左心室每搏输出量（LVSV）、左心室射血分数（LVEF）均明显小于单支组，差异均具有显著性（P＜0.05）。B组患者LVEDV、LVESV均明显大于A组， LVSV、LVEF明显小于A组，差异均具有显著性（P＜0.05）。D组患者LVEDV、LVESV均明显大于C组，LVSV、LVEF明显小于C组，差异均具有显著性（P＜0.05）。结论实时三维超声心动图能够客观地反映冠状动脉病变患者的左室重构程度，可作为有效的临床评估指标。
Objective To evaluate the clinical value of real-time 3D echocardiography on coronary artery disease. Method 60 patients with coronary heart disease were selected from October 2013 to October 2014 in our hospital diagnosed cases of coronary angiography, according to the lesion involved the scope were divided into single vessel group and multi group, 30 cases in each group. According to the degree of stenosis of single branch group were divided into group A （the degree of coronary artery stenosis in 50%） and group B （the degree of coronary artery stenosis in 50%~75%）, 15 cases in each group;multi group were divided into group C （the degree of coronary artery stenosis in 50%） and group D （the degree of coronary artery stenosis in 50%~75%）, 15 cases in each group. Compared of single vessel group, multi branch of left ventricular in patients with coronary artery stenosis group parameters, and compared of the two groups in different degrees of coronary artery stenosis in patients with left ventricular parameters. Result LVEDV and LVESV of multi branch group patients were signiifcantly greater than the single group, LVSV and LVEF of multi branch group patients were signiifcantly less than the single group, there was signiifcant difference （P〈0.05）;patients in the group B LVEDV, LVESV were signiifcantly higher than those in group A, LVSV, LVEF were less than that of group A, there was signiifcant difference（P 〈 0.05）;patients in group D LVEDV, LVESV were signiifcantly higher than those in group C, LVSV, LVEF were less than that of group C, there was signiifcant difference （P〈0.05）. Conclusion Real-time 3D echocardiography could objectively relfect the degree of left ventricular remodeling in patients with coronary artery disease, maybe used as a clinical evaluation of the effective index.
