The Systolic Blood Pressure Intervention Trial (SPRINT) compared the clinical outcomes between target systolic blood pressure (SBP) levels between 140 and 120 mmHg or lower. Both,the 2017 ACC/AHA and the 2018 ESC/ESH guidelines in hypertension are derived from the SPRINT trial and advise initiation and/or intensification of treatment at lower blood pressure thresholds. The ACC/AHA guidance supersedes the 2014 Eight Joint National Committee guideline (JNC-8) which advised initiation of treatment when the BP was 140/90 mmHg or higher; in adults 60 years or over, the target was 150/90 mmHg. Compared to JNC-8, the new guidelines lower the SBP target by 10 mmHg in patients under age of 60 years, and by 20 mmHg in the elderly. We performed a qualitative multi-dimensional analysis in order to answer two key questions: will the new guidelines deliver the stated benefits? and, will translation to the clinic be simple, risk-free, and affordable? A major investment by national healthcare administrations will be necessary for the initiation and support of this program but this decision can only be justified by a valid expectation of clinical benefit. At this time, a definitive answer is not available and a "wait and see" attitude appears appropriate and reasonable. In the interim, efforts are best directed to the immediate problem of untreated hypertension worldwide.
收缩压干预试验(SPRINT)比较了目标收缩压(SBP)水平在 140mmHg 至 120mmHg 或更低之间的临床结果。2017 年美国心脏病学会/美国心脏协会(ACC/AHA)和 2018 年欧洲心脏病学会/欧洲高血压学会(ESC/ESH)高血压指南均源自 SPRINT 试验,并建议在更低的血压阈值下开始和/或加强治疗。ACC/AHA 指南取代了 2014 年的八项联合国家委员会指南(JNC-8),该指南建议当血压为 140/90mmHg 或更高时开始治疗;对于 60 岁或以上的成年人,目标是 150/90mmHg。与 JNC-8 相比,新指南将 60 岁以下患者的 SBP 目标降低了 10mmHg,老年患者降低了 20mmHg。为了回答两个关键问题,我们进行了定性多维分析:新指南是否会带来预期的益处?并且,向临床转化是否简单、无风险且负担得起?国家医疗保健管理部门需要进行重大投资,以启动和支持该计划,但只有在有合理的临床获益预期的情况下,才能做出这一决定。目前,还没有明确的答案,“观望”的态度似乎是合适和合理的。在此期间,最好将精力集中在全球未治疗高血压的紧迫问题上。
