很多老年人都害怕患高血压,而认为血压低些没关系。其实这是一种误解,低血压同样会对健康造成危害,因为它会促进缺血性中风的发生,成为间接危险。这是因为血压偏低的老年人血流缓慢,血液黏稠度高,脑部供血不足引起缺血缺氧。加之动脉硬化,血管腔变得狭窄,血管壁弹性减弱,因此容易形成血栓而导致缺血性中风。
Many older people are afraid to suffer from high blood pressure, but it does not matter if the blood pressure is low. In fact, this is a misunderstanding. Hypotension will also be harmful to health as it will promote the occurrence of ischemic stroke and become an indirect danger. This is because the elderly people with low blood pressure have slow blood flow, high blood viscosity and lack of blood supply to the brain that cause ischemia and hypoxia. Coupled with atherosclerosis, the blood vessel becomes narrow, the elasticity of the blood vessel wall weakened, so easy to form a thrombus and lead to ischemic stroke.
