摘要
目的:探究彩色多普勒超声心动图(CDE)联合心肌声学造影(MCE)对心肌缺血患者冠脉狭窄程度的临床诊断价值。方法:选取2019.1-2020.6期间本院心血管科收治的心肌缺血患者32例作为研究对象,入院后行冠状动脉造影(CAG)、CDE和MCE检查。以CAG诊断结果为基准,对CDE和MCE诊断心肌缺血患者冠状动脉狭窄正确率、特异性和灵敏性程度进行比较。将心肌室壁运动异常、心肌缺血、心绞痛、每搏输出量和射血分数作为自变量,将冠脉狭窄程度(CAG阳性)作为因变量进行Logistic多因素回归分析。结果:CAG检测结果显示,32例心肌缺血患者冠状动脉狭窄者28例,MCE诊断敏感性92.86%;特异性97.53%,诊断正确率94.92%;CDE诊断敏感性89.29%,特异性75.00%,诊断正确率91.33%;MCE联合CDE诊断敏感性98.72%,特异性96.85%,诊断正确率99.37%。Logistic多因素回归分析结果显示,心肌室壁运动异常、心肌缺血和心绞痛是CAG阳性的独立危险因素,每搏输出量和射血分数不是CAG阳性的独立危险因素。结论:彩色多普勒超声心动图联合心肌声学造影对心肌缺血冠脉狭窄的诊断价值突出。
Objective:To explore the clinical diagnostic value of color Doppler echocardiography(CDE)combined with myocardial contrast echocardiography(MCE)for coronary artery stenosis in patients with myocardial ischemia.Methods:Thirty-two patients with myocardial ischemia admitted to the Department of Cardiovascular Diseases of our hospital during the period 2019.1-2020.6 were selected as the research objects.Coronary angiography(CAG),CDE and MCE were performed after admission.The CAG examination results were used as the standard for evaluating coronary artery stenosis,and the accuracy,specificity and sensitivity of coronary artery stenosis in patients with myocardial ischemia were compared between CDE and MCE.The abnormal myocardial wall motion,myocardial ischemia,angina pectoris,stroke volume and ejection fraction were used as independent variables,and the degree of coronary artery stenosis(CAG positive)was used as the dependent variable to perform Logistic multivariate regression analysis.Results:CAG test results showed that 28 patients with coronary artery stenosis in 32 patients with myocardial ischemia,MCE diagnosis sensitivity was 92.86%;specificity was 97.53%,diagnosis accuracy rate was 94.92%;CDE diagnosis sensitivity was 89.29%,specificity was 75.00%,The diagnostic accuracy rate was 91.33%;the diagnostic sensitivity of MCE combined with CDE was 98.72%,the specificity was 96.85%,and the diagnostic accuracy rate was 99.37%.Logistic multivariate regression analysis showed that abnormal myocardial wall motion,myocardial ischemia and angina pectoris were independent risk factors for CAG positive,and stroke volume and ejection fraction were not independent risk factors for CAG positive.Conclusion:Color Doppler echocardiography combined with myocardial contrast echocardiography has outstanding diagnostic value for myocardial ischemic coronary stenosis.
