目的评价超声心动图和冠脉造影对诊断冠心病的相关性。方法将超声心动图及冠脉造影在47例冠心病中的阳性检出率进行对比分析。结果冠脉造影对冠心病诊断准确率较高,而二维超声诊断冠心病准确率较低,经统计学检验,二者差异有统计学意义(P<0.05)。结论冠状动脉造影是目前较能客观显示冠状动脉病变范围和狭窄程度的一种可靠检查方法。
Objective To evaluate the correlation between echocardiography and coronary angiography in the diagnosis of coronary heart disease. Methods The positive rate of echocardiography and coronary angiography in 47 cases of coronary heart disease were compared. Results Coronary angiography had a higher diagnostic accuracy for coronary heart disease, while the accuracy of two-dimensional ultrasound in diagnosing coronary heart disease was lower. The difference was statistically significant (P <0.05). Conclusion Coronary angiography is a reliable method to objectively display the extent and severity of coronary lesions.
