Systolic hypertension is difficult to control in the elderly, but this is not an excuse for denying these patients the benefits of carefully controlled antihypertensive treatment, particularly when target organ disease is present. Although drug therapy may produce alarming symptoms, it is highly doubtful that it increases the incidence of myocardial infarction or permanent neurologic damage. In fact, evidence indicates that antihypertensive therapy may prevent hemorrhagic and thrombotic strokes. Arterial pressure should be reduced slowly and cautiously--to allow control without interfering with cerebral flow stability. Drug therapy should be started in small doses and may be initiated with diuretics. Methyldopa in small or moderate doses has been effective and does not often cause postural hypotension. Drugs that interfere with reflex arteriolar constriction should not be used.
收缩期高血压在老年人中难以控制,但这并非拒绝给予这些患者精心控制的抗高血压治疗益处的借口,尤其是当存在靶器官疾病时。尽管药物治疗可能会产生令人担忧的症状,但极有可能它会增加心肌梗死或永久性神经损伤的发生率。事实上,有证据表明抗高血压治疗可能预防出血性和血栓性中风。动脉压应缓慢、谨慎地降低——以便在不干扰脑血流稳定性的情况下实现控制。药物治疗应从小剂量开始,可从利尿剂开始使用。小剂量或中等剂量的甲基多巴已证明有效,且不常引起体位性低血压。不应使用干扰反射性小动脉收缩的药物。
