The older hypertensive patient (greater than or equal to 60 years) is at progressive risk of suffering from cardiovascular complications of hypertension (heart attack, congestive heart failure, stroke, occlusive peripheral arterial disease and renal failure). In this age group, hypertension is quantified as a blood pressure equal to or greater than 160/95mm Hg (average of 3 times 3 readings). With an increasing baseline risk, the returns of antihypertensive treatment increase, at least up to the age of 80 years. Prospective therapeutic trials have shown considerable benefits regarding prevention of stroke and congestive heart failure. This particularly applies to thiazide-type diuretics. Before any treatment is undertaken, the cardiovascular status of the older hypertensive patient should be assessed with utmost care, because target organ damage may turn the normalisation of blood pressure into a disadvantage. The profiles of currently available drugs are reviewed against the background of aging. There is not yet any firm evidence to support the thesis that some drug classes are better suited than others for treating older hypertensive patients, although some caution with alpha 1-blockers and centrally acting agents seems appropriate. Finally, some practical recommendations are presented on the build-up of optimum therapy in individual patients.
老年高血压患者(年龄大于或等于60岁)罹患高血压心血管并发症(心脏病发作、充血性心力衰竭、中风、闭塞性外周动脉疾病和肾衰竭)的风险不断增加。在这个年龄组中,高血压的定义为血压等于或高于160/95mmHg(3次测量,每次测量3个读数的平均值)。随着基线风险的增加,降压治疗的获益也会增加,至少在80岁之前如此。前瞻性治疗试验已表明,在预防中风和充血性心力衰竭方面有显著益处。这尤其适用于噻嗪类利尿剂。在进行任何治疗之前,应极其谨慎地评估老年高血压患者的心血管状况,因为靶器官损害可能会使血压正常化变为不利因素。本文在衰老的背景下对现有药物的特点进行了综述。目前尚无确凿证据支持某些药物类别比其他药物类别更适合治疗老年高血压患者这一论点,不过对α1受体阻滞剂和中枢作用药物似乎应有所谨慎。最后,针对个体患者优化治疗方案的制定提出了一些实用建议。
