摘要
目的:探究经胸彩色多普勒超声诊断冠心病(CHD)的临床优势。方法:我院疑似为CHD的患者100例根据CAG结果分为非CHD组(48例)和CHD组(52例),比较两组经胸彩色多普勒超声心动图检测结果,以CAG结果为金标准,分析经胸彩色多普勒超声心动图诊断冠心病敏感性、特异性、准确度、阳性预测值和阴性预测值。结果:与非CHD组比较,CHD组左房内径[(3.21±0.41)cm比(3.85±0.37)cm]、左室内径[(4.44±0.39)cm比(4.81±0.32)cm]、室间隔厚度[(0.95±0.11)cm比(1.06±0.13)cm]、左室后壁厚度[(0.9±0.14)cm比(1.1±0.13)cm]和左室等容舒张时间[(68.11±11.29)ms比(78.32±13.40)ms]均显著增加,舒张早期E峰血流速度[(0.79±0.17)m/s比(0.65±0.15)m/s]、E峰减速时间[(215.35±18.43)ms比(195.36±21.43)ms]和左室舒张早期峰值流速/晚期峰值流速(E/A)比值[(1.22±0.18)比(0.94±0.37)]均显著减少,P均=0.001;经胸彩色多普勒超声心动图诊断CHD(阳性)的有42例,非冠心病(阴性)有58例,以冠脉造影为金标准,计算其诊断的敏感度为76.92%、特异性为95.83%、准确度为86.00%、阳性预测值95.24%、阴性预测值79.31%。结论:经胸彩色多普勒超声心动图诊断冠心病有较高的敏感性、特异性、准确度,是一种安全、准确、简便、无创、经济的检查方法。
Objective:To explore clinical advantages of transthoracic color Doppler echocardiography in diagnosis of coronary heart disease(CHD).Methods:According to CAG results,a total of 100 patients suspected of CHD in our hospital were divided into non-CHD group(n=48)and CHD group(n=52).Results of transthoracic color Doppler echocardiography were compared between two groups.With CAG results as gold standard,sensitivity,specificity,accuracy,positive and negative predictive value of transthoracic color Doppler echocardiography in diagnosing CHD were analyzed.Results:Compared with non-CHD group,there were significant rise in left atrial diameter[(3.21±0.41)cm vs.(3.85±0.37)cm],left ventricular diameter[(4.44±0.39)cm vs.(4.81±0.32)cm],interventricular septal thickness[(0.95±0.11)cm vs.(1.06±0.13)cm],left ventricular posterior wall thickness[(0.9±0.14)cm vs.(1.1±0.13)cm]and left ventricular isovolumic relaxation time[(68.11±11.29)ms vs.(78.32±13.40)ms],and significant reductions in early diastolic E peak velocity[(0.79±0.17)m/s vs.(0.65±0.15)m/s],E peak deceleration time[(215.35±18.43)ms vs.(195.36±21.43)ms]and left ventricular early/late diastolic peak velocity(E/A)[(1.22±0.18)vs.(0.94±0.37)]in CHD group,P=0.001 all;42 cases of CHD(positive)and 58 cases of non-coronary heart disease(negative)were diagnosed by chest color Doppler echocardiography,using coronary angiography as the gold standard,to calculation its sensitivity,specificity,accuracy,positive and negative predictive value in diagnosing CHD was 76.92%,95.83%,86.00%,95.24%and 79.31%respectively.Conclusion:Transthoracic color Doppler echocardiography possesses high sensitivity,specificity and accuracy in the diagnosis of CHD.It is a safe,accurate,simple,noninvasive and economic examination method.
