摘　　要：目的:探讨超声心动图(UCG)诊断冠心病节段性室壁运动异常的应用价值。方法:选取2020年1-12月阳江市人民医院超声医学科收治的疑似冠心病患者762例为观察对象,均行UCG与冠状动脉造影(CAG)检查,以CAG为金标准,分析UCG对冠心病的诊断价值,比较UCG检查诊断不同的冠状动脉管腔狭窄面积及冠状动脉病变血管支数的敏感度。结果:UCG诊断冠心病敏感度48.8%,特异度98.0%,阴性预测值56.4%,阳性预测值97.4%,准确度68.6%;UCG诊断冠状动脉狭窄程度介于50%~75%的患者节段性室壁运动异常的敏感度为14.5%,当冠状动脉狭窄程度>75%时,敏感度63.9%,UCG诊断冠心病准确度随冠状动脉狭窄程度的加重而提高,差异有统计学意义(P<0.001);UCG诊断单支病变、双支病变、三支病变的敏感度为31.1%、47.8%、58.9%,UCG诊断敏感度随病变血管支数增加提高,差异有统计学意义(P<0.001)。结论:UCG和冠脉造影检查诊断冠心病节段性室壁运动异常具有较好的一致性。Objective:To investigate the application value of ultrasound cardiogram(UCG)for the diagnosis of segmental ventricu⁃lar wall motion abnormalities in coronary artery disease.Methods:Seven hundred and sixty-two patients with suspected coronary ar⁃tery disease admitted to the Department of Ultrasound Medicine of Yangjiang People's Hospital from January to December 2020 were selected as observation subjects,and all of them underwent UCG and coronary arteriography(CAG).Using CAG as the gold standard,the diagnostic value of UCG for coronary artery disease was analyzed.The sensitivity of UCG examination in diagnosing different coronary artery lumen stenosis area and the number of coronary artery diseased vessel branches was compared.Results:The sensitivity of UCG in diagnosing coronary artery disease was 48.8%,the specificity was 98.0%,the negative predictive value was 56.4%,the positive predictive value was 97.4%,and the accuracy was 68.6%.The sensitivity of UCG in diagnosing segmental ventricular wall motion abnormalities in patients with coronary artery stenosis between 50%and 75%was 14.5%.When the degree of coronary artery stenosis was>75%,the sensitivity was 63.9%.The accuracy of UCG for the diagnosis of coronary artery disease increased with the degree of coronary stenosis,and the difference was statistically significant(P<0.001).The sensitivity of UCG in diagnosing single-branch lesions,double-branch lesions,and triple-branch lesions was 31.1%,47.8%,and 58.9%,and the diag⁃nostic sensitivity of UCG increased with the increase of the number of branches of the lesioned vessels,and the difference was sta⁃tistically significant(P<0.001).Conclusion:UCG and coronary angiography have good agreement in diagnosing segmental ventricu⁃lar wall motion abnormalities in coronary artery disease.
