在什么时候治疗高血压往往成为讨论的中心问题;把血压降低到什么程度则很少谈及。如果通过治疗能够完全消除高血压的危险,答案就很简单了——在无症状性高血压的情况下,越低越好。然而,过度热衷于降低血压是令人担心的。血压的急剧下降并不使血液循环恢复到以前的状态。高血压引起的血管改变只能缓慢地(也许只能部分地)反回原状。所以高血压 Treatment of high blood pressure often becomes a central issue of discussion; the extent to which blood pressure is reduced is seldom discussed. The answer is simple if the risk of high blood pressure can be completely eliminated by treatment - in the case of asymptomatic hypertension, the lower the better. However, being overly enthusiastic about lowering blood pressure is worrying. The sharp drop in blood pressure does not return the blood circulation to the previous state. Vascular changes caused by high blood pressure can only (slowly, perhaps only partially) return to their original status. So high blood pressure
