People with prehypertension undoubtedly have an increased risk of cardiovascular and other complications. The vast majority have low absolute risk and whether drug treatment would be beneficial is uncertain. While pharmacotherapy has attractions from a public health prospective, clinicians and crucially those with prehypertension require robust evidence that drug treatment will lead to short-term as well as long-term gains. Any changes in recommendations should await adequately powered outcome studies, which provide solid evidence of the magnitude of absolute risk reduction in treating prehyper-tension and assessment of the cost-effectiveness.
血压正常高值的人群无疑有更高的心血管及其他并发症风险。绝大多数人的绝对风险较低,药物治疗是否有益尚不确定。虽然从公共卫生角度来看药物治疗有吸引力,但临床医生,尤其是血压正常高值的患者需要有力证据证明药物治疗能带来短期和长期益处。建议的任何改变都应等待有足够效力的结局研究,这些研究能提供治疗血压正常高值时绝对风险降低幅度的可靠证据以及成本效益评估。
