Hypertension is the most commonly diagnosed condition in persons aged 60 and older and is the single most important risk factor for cardiovascular disease (ischemic heart disease, heart failure, and stroke), kidney disease, and dementia. More than half of individuals with hypertension in the United States are aged 60 and older. Hypertension disproportionately affects African Americans, with all age groups, including elderly adults, having a higher burden of hypertension-related complications than other U.S.
Multiple clinical trials have demonstrated the beneficial effects of blood pressure (BP) reduction on cardiovascular morbidity and mortality, with most of the evidence in individuals aged 60 and older. Several guidelines have recently been published on the specific management of hypertension in individuals aged 60 and older, including in high-risk groups such as African Americans. Most recommend careful evaluation, thiazide diuretics and calcium-channel blockers for initial drug therapy in most African Americans, and angiotensin-converting enzyme inhibitors and angiotensin receptor blockers in those with chronic kidney disease or heart failure. Among the areas of controversy is the recommended target BP in African Americans aged 60 and older. A recent U.S. guideline recommended raising the systolic BP target from less than 140 mmHg to less than 150 mmHg in this population. This article will review the evidence and current guideline recommendations for hypertension treatment in older African Americans, including the rationale for continuing to recommend a SBP target of less than 140 mmHg in this population.
高血压是60岁及以上人群中最常被诊断出的疾病,并且是心血管疾病(缺血性心脏病、心力衰竭和中风)、肾脏疾病和痴呆症的唯一最重要风险因素。在美国,超过一半的高血压患者年龄在60岁及以上。高血压对非裔美国人的影响尤为严重,所有年龄组,包括老年人,与高血压相关的并发症负担都高于其他美国人群。
多项临床试验已证明降低血压(BP)对心血管发病率和死亡率的有益影响,大多数证据来自60岁及以上的个体。最近已发布了几项关于60岁及以上个体高血压具体管理的指南,包括针对非裔美国人等高风险群体。大多数指南建议进行仔细评估,对于大多数非裔美国人,噻嗪类利尿剂和钙通道阻滞剂用于初始药物治疗,而对于患有慢性肾病或心力衰竭的患者,则使用血管紧张素转换酶抑制剂和血管紧张素受体阻滞剂。争议领域之一是60岁及以上非裔美国人的推荐血压目标。最近一项美国指南建议将该人群的收缩压目标从低于140 mmHg提高到低于150 mmHg。本文将回顾关于老年非裔美国人高血压治疗的证据和当前指南建议,包括在该人群中继续推荐收缩压目标低于140 mmHg的理由。
