多巴酚丁胺负荷超声结合多普勒组织成像技术检测冬眠心肌的研究进展

Study Progress of Dobutamine Stress Echocardiography with Doppler Tissue Imaging in the Detection of Hibernating Myocardium

多巴酚丁胺负荷超声是目前世界上广泛应用的检测冬眠心肌的有效方法,具有较高的敏感性和特异性,但其图像分析采用半定量目测法,结果的分析判断易受主观因素影响,带有较强的经验依赖性。组织多普勒是近年发展起来的一项定量分析室壁运动的超声新技术,与多巴酚丁胺负荷超声相结合可弥补其半定量目测法的不足。

Dobutamine stress echocardiography is the effective method in the detection of hibernating myocardium,which is widespread used in the most countries and have the high sensitivity and specificity.The image analysis often uses demi-quantitative visual analysis for myocardial ischemia,its major limitation is related to a high inter-observer variability and operator-dependent expertise.Recently,Tissue Doppler Imaging as a new technology provides a quantitative analysis of regional myocardial function.Dobutamine stressechocardiography with Doppler Tissue Imaging might overcome the limitation of the demi-quantitative visual analysis.
