动脉粥样硬化的发展过程分4期: 1.无症状期或称隐匿期 其过程长短不一,包括从较早的病理变化开始,直到动脉粥样硬化已经形成,但尚无器官或组织受累的症状。 2.缺血期 由于血管狭窄、器官缺血而产生症状。 3.坏死期 由于血管内血栓形成或管腔闭塞而产生器官组织坏死的症状。 4.纤维化期 长期缺血,器官组织纤维化和萎缩而引起症状。不少患者不经过坏死期而进入纤维化期,而在纤维化期的患者也可重新发生缺血期的表现。按受累动脉部位
The development of atherosclerosis in four stages: 1. Asymptomatic or hidden period of the process of varying length, including from the early pathological changes until atherosclerosis has been formed, but no organ or tissue involvement Symptoms. 2. Ischemic period due to vascular stenosis, organ ischemia and symptoms. Necrotic stage of necrosis due to intravascular thrombosis or lumen occlusion and the symptoms of organ tissue necrosis. 4 fibrosis period of long-term ischemia, organ tissue fibrosis and atrophy caused by symptoms. Many patients enter the fibrosis stage without going through the necrotic stage, whereas those in the fibrotic stage may re-develop their ischemic stage. By affected artery site
