目的探讨经胸彩色多普勒超声心动图(CDE)在冠心病诊断中的价值。方法通过回顾性地对246例临床疑似冠心病患者的超声心动图(CDE)检查结果与冠状动脉造影(CAG)检查作对照,评价CDE对冠心病的诊断价值。结果246例临床疑似为冠心病患者经CAG检查明确了冠心病的诊断共139例,其中72例CDE检出室壁节段运动异常,107例非CHD患者经CDE诊断排除了93例,CDE诊断CHD的阳性预测值和特异度分别为83.72%、86.92%。结论CDE作为一种无创性快速诊断方法,以其较高的阳性预测值和特异度可应用于临床冠心病早期诊断。
Objective To investigate the value of transthoracic color Doppler echocardiography (CDE) in the diagnosis of coronary heart disease. Methods The diagnostic value of CDE on coronary heart disease was evaluated retrospectively on 246 echocardiography (CDE) and coronary angiography (CAG) in patients with clinically suspected coronary heart disease. Results A total of 139 cases of coronary heart disease were diagnosed by coronary angiography in 246 patients suspected of coronary heart disease. Of these, 139 cases were diagnosed as coronary artery disease by coronary angiography, of which 72 cases had abnormal motion of the wall segment in CDE. 93 cases were diagnosed by CDE in 107 cases of non-CHD, The positive predictive value and specificity of CHD were 83.72% and 86.92% respectively. Conclusion CDE as a noninvasive rapid diagnostic method, with its high positive predictive value and specificity can be applied to the early diagnosis of clinical coronary heart disease.
