背景 通常认为稳定型转化为不稳定型心绞痛的机制是冠脉内斑块破裂和血栓形成。但仅在致命性不稳定型心绞痛这一亚组的病人中得到了肯定的组织病理学依据。通过对经血管造影证实冠脉内无血栓形成的不稳定型心绞痛病人的定向冠脉内粥样斑块切除标本进行组织病理学和免疫组织病理学的
Background It is generally accepted that the mechanism by which stable conversion to unstable angina pectoris is intraluminal plaque rupture and thrombosis. However, positive histopathological evidence has been obtained only in patients in the subgroup of fatal unstable angina. Stereotactic and immunohistopathological studies were performed on targeted atherosclerotic plaque resections of patients with unstable angina pectoris confirmed by angiography in the coronary artery
