超声心动图在冠心病心功能评价中的应用进展

以往认为，超声心动图对于冠心病的诊断缺乏特异性和敏感性，近十几年来，随着现代电子、器材等高新技术不断引入超声诊断仪，彩色室壁运动分析(CK)技术、组织多普勒显像(DTI)、解剖M型超声心动图(AME)、心肌造影超声心动图(MCE)等无创性超声新技术逐步从基础走向临床，广泛用于冠心病的诊断及疗效评估，尤其是心功能评价，为临床研究冠心病提供了更直观、更量化的诊断依据。

New developments of echocardiography in assessing ventricular function in coronary artery disease

Echocardiography was once clinically considered as a tool for diagnosing coronary artery disease with limited sensitivity and specificity. Recently with the developments of modern electronic technologies,limitations of poor image quality were overcome and several new technical modalities,such as color kinesis(CK),Doppler tissue imaging(DTI)and anatomic M-mode echocardiography(AME)have been demonstrated to be useful for enhancing the accuracy and clinical applicability of the echocardiography. These new noninvasive ultrasonic technologies,adding more direct and quantitative information on specific topics of cardiac function,may play an important role in the study of coronary artery disease.
