An elevated systolic but not diastolic blood pressure level represents a common finding in elderly patients and is associated with an increased risk for developing coronary artery disease, cerebrovascular disease, peripheral artery disease, progressive cognitive decline and renal failure. Although less frequently, elderly patients manifest not only with systolic but also diastolic hypertension. Also in this case, the elderly patient will present an increased risk for developing hypertension-related abnormalities. Based on several trials conducted in patients ≥65 years and one single trial in patients ≥80 years the most recent European guidelines recommend antihypertensive treatment in elderly hypertensive patients with a systolic blood pressure ≥60 mmHg, with a systolic target between 140 and 150 mmHg. In fit elderly patients <80 years treatment may be considered at a systolic level ≥140 mmHg with a target SBP <140 mmHg if treatment is well tolerated. Despite of the above, at least three issues related to antihypertensive drug treatment in aged individuals are still debated, particularly after the publication of a recent large scale clinical trial that included also 2.636 patients ≥75 years and a study in nursing home residents ≥80 years, i.e. the frailest oldest patients: (1) the blood pressure threshold at which antihypertensive drug should be initiated, (2) the blood pressure targets of the therapeutic intervention, and (3) the approach to frail elderly hypertensive patients. This review will critically review the evidence available so far on these important issues as well as the position of current guidelines and consensus statements.
收缩压升高但舒张压正常是老年患者的常见表现,与患冠状动脉疾病、脑血管疾病、外周动脉疾病、进行性认知衰退和肾衰竭的风险增加相关。老年患者较少出现单纯收缩期高血压,也有部分患者表现为舒张期高血压。在此情况下,老年患者发生高血压相关异常的风险也会增加。基于针对≥65岁患者开展的多项试验以及一项针对≥80岁患者的试验,最新欧洲指南建议,收缩压≥160 mmHg的老年高血压患者应接受降压治疗,收缩压目标值为140至150 mmHg。对于年龄<80岁的健康老年患者,如果治疗耐受性良好,收缩压≥140 mmHg时可考虑治疗,目标收缩压<140 mmHg。尽管如此,老年个体降压药物治疗仍存在至少三个有争议的问题,尤其是在一项纳入2636例≥75岁患者的大型临床试验以及一项针对≥80岁养老院居民(即最虚弱的老年患者)的研究发表之后:(1)开始使用降压药物的血压阈值;(2)治疗干预的血压目标;(3)老年虚弱高血压患者的治疗方法。本综述将严格审视目前关于这些重要问题的现有证据以及当前指南和共识声明的立场。
