原发性高血压是诱发主动脉夹层(AD)发生发展的一种重要因素。可能与引起的血流动力学异常及促进动脉粥样硬化发展相关。AD是因动脉内膜破裂,高压血流冲入血管壁造成内膜与中膜分离并沿主动脉长轴方向扩展形成真假二个通道。虽发生率低,但危害极大,自然愈后极差,是心血管疾病中? Essential hypertension is a predominant factor in the development of aortic dissection (AD). It may be associated with abnormal hemodynamics and promote the development of atherosclerosis. AD is due to rupture of the arterial intima, high blood pressure into the blood vessel wall caused by intima and media separation and along the long axis of the aortic expansion to form true and false two channels. Although the incidence is low, but the great harm, the natural worse, is cardiovascular disease?
