急性冠脉综合征(ACS)是以冠状动脉粥样硬化斑块破裂或侵蚀,继发完全或不完全闭塞血栓形成,从而引起不同程度的冠状动脉病变为病理基础的一组临床综合征,包括不稳定型心绞痛(UA)、非ST段抬高型心肌梗死(NSTEMI)及ST段抬高型心肌梗死(STEMI)。老年急性冠脉综合征(GACS)是最常见的老年心血管病急症,也是老年住院心脏病患者中占比例较多的疾病。 Acute coronary syndrome (ACS) is a group of clinical syndromes characterized by the rupture or erosion of coronary atherosclerotic plaques secondary to complete or incomplete occlusion of thrombosis resulting in varying degrees of coronary artery disease as a pathological basis including UA, NSTEMI, and STEMI. Geriatric Acute Coronary Syndrome (GACS) is the most common acute cardiovascular disease and is a disease that accounts for a large proportion of elderly hospitalized heart patients.
