老年人降压切忌贪多求快,短期内降幅最好不要超过原血压的20%,否则很容易因为血压波动过大诱发脑梗塞等严重的后遗症。因为60岁以上的老年高血压患者由于其生理机能减退,或多或少会有一些代谢紊乱和心脑血管病变的存在。如果血压降得过快、过猛,会导致大脑和心脏供血不足,血流减慢,可反射性地引起脑血管痉挛,血小板沉积引起脑血栓形成,就会有发生脑梗塞的风险。
Antihypertensive elderly should not be greedy seek faster, the best short-term decline should not exceed 20% of the original blood pressure, otherwise it is easy because of excessive blood pressure induced cerebral infarction and other serious consequences. Because over the age of 60 elderly hypertensive patients due to their physiological decline, more or less there will be some metabolic disorders and the existence of cardiovascular and cerebrovascular diseases. If the blood pressure drops too fast, too much, can lead to insufficient blood supply to the brain and heart, blood flow can be reflex caused by cerebral vasospasm, platelet deposition caused by cerebral thrombosis, there will be the risk of cerebral infarction.
