不稳定型心绞痛的临床表现及其病理生理与稳定型心绞痛均不相同,但冠状动脉造影定量分析结果常无明显差别,即病变的冠状动脉数及其阻塞的程度无明显差异.相反地,冠状动脉各种形态的病变性质却可反应其各别的病理背景,对不稳定型心绞痛的冠状动脉造影进行定性分析可给各种临床表现提供相应的病理改变背景。
The clinical manifestations of unstable angina and its pathophysiology and stable angina pectoris are not the same, but the results of quantitative coronary angiography often no significant difference, that is, the lesion coronary artery and the extent of its obstruction no significant difference.Conversely, coronal Various morphological features of the artery can reflect its respective pathological background, qualitative analysis of coronary angiography of unstable angina can provide a variety of clinical manifestations of the corresponding pathological changes in the background.
