摘　　要：目的观察超声心动图检查在冠心病伴左室功能不全患者冠脉支架术中的应用。方法选取我院2015年3月~2017年3月收治的200例冠心病伴左室功能不全患者以及100例进行常规体检的健康个体为本次研究对象,200例冠心病伴左室功能不全患者均进行冠脉支架术即为支架组,100例进行常规体检的健康个体为对照组,比较支架组患者行冠脉支架术前与对照组患者超声心动检查左室容量、左室舒张功能指标差异性以及支架组患者行冠脉支架术前后超声心动图检查左心室相关检测数据变化情况。结果支架组患者行冠脉支架术前左室收缩容积(LVESV)、左室舒张末期容积(LVEDV)明显高于对照组,左室射血分数(LVEF)明显小于对照组,二尖瓣舒张期最大血流频谱测定左心室Ep/Ap、Aa/Ea、左前降支(LAD)明显高于对照组,支架组患者进行冠脉支架术后LVESV、LVEDV、LVEF、Ep/Ap、Aa/Ea以及LAD各项数据变化明显,差异有统计学意义(P<0.05)。结论对于冠心病伴左室功能不全进行冠脉支架术的个体患者进行超声心动图检查有利于医师了解个体左心室容量以及功能改善情况。Objective To observe the application of echocardiography in coronary stenting in the patients with coronary heart disease complicated with left ventricular dysfunction. Methods 200 patients with coronary heart disease complicated with left ventricular dysfunction who were admitted in our hospital from March 2015 to March 2017 and 100 healthy individuals who underwent routine physical examination were selected as the study subjects. 200 cases of coronary heart disease complicated with left ventricular dysfunction who were given coronary stenting were assigned to the stenting group, and 100 cases of healthy subjects who were given routine physical examination were assigned to the control group. The differences of the left ventrieular volume, left ventricular diastolic function index were compared between the stenting group before coronary stenting and control group, and the changes of relevant test data of the left ventricle by echocardiography in the stenting group before and after coronary stenting were compared. Results Left ventricular systolic volume （LVSV） and left ventrieular end diastolic volume （LVEDV） in the stenting group before coro- nary stenting were significantly higher than those in the control group, and the left ventricular ejection fraction （LVEF） was significantly lower than that in the control group. During the mitral diastolic period, the maximum blood flow spectrum measured that the left ventricular Ep/Ap, Aa/Ea, and left anterior descending （LAD） were significantly higher than those in the control group. The changes of the data of LVESV, LVEDV, LVEF, Ep/Ap, Aa/Ea and LAD after coronary stenting in the individuals in the stenting group were significant, and the differences were statistically significant（P〈 0.05）. Conclusion Echocardiographic examination of individual patients undergoing coronary stenting for coronary heart disease complicated with left ventricular dysfunction is beneficial to physicians in understanding individual LV volume and functional improvement.
