Clinical Outcome of Aortic Dissection

Aortic dissection refers to the blood in the aortic lumen entering the aortic mediastinum from the tear of the aortic intima, separating the mediastinum and extending along the long axis of the aorta to form the true and false separation state of the aortic wall. Risk factors for aortic dissection included hypertension, cystic necrosis or degeneration of the middle aorta, hereditary connective tissue disease, congenital two-lobe active pulse valve, arteritis, aneurysm, atherosclerosis and iatrogenic injury, etc. The leading cause of aortic dissection is hypertension, and more than 75% of aortic dissection is associated with hypertension.Therefore, for hypertension patients to do a good job in the prevention and control of hypertension, pay attention to the regular use of antihypertensive drugs and monitoring blood pressure. In case of sudden chest and back lacerations, the patient should be immobilized in bed, contacted with an ambulance and sent to the hospital for emergency treatment, so as to avoid greater risks. The aim of this study is analyze clinical outcome of Chinese patients with acute aortic dissection.
