自发性冠状动脉夹层(spontaneous coronary artery dissection,SCAD)为一种少见的可导致急性冠状动脉综合征、甚至猝死的冠状动脉疾病。其主要表现为冠状动脉内膜自发撕裂或冠状动脉壁内滋养血管出血形成血管夹层,影响正常冠状动脉血液供应。常常与冠状动脉粥样硬化、围产期女性体内激素水平改变、动脉壁中层结构变异、剧烈运动等因素相关。往往被误诊为冠心病心绞痛、心肌梗死或腹痛。故早期诊断、及时治 Spontaneous coronary artery dissection (SCAD) is a rare coronary artery disease that causes acute coronary syndrome and even sudden death. Its main manifestations of spontaneous rip incision of the coronary artery or blood vessels within the coronary artery nourish vascular dissection, affecting the normal coronary blood supply. Often with coronary atherosclerosis, perinatal women’s hormone levels change, the middle wall of the arterial wall structure variation, strenuous exercise and other factors.
