J Clin Hypertens:中国学者认为糖尿病把130 mmHg作为降压药门槛不可取

2019-02-05 卢芳 中国循环杂志

对于糖尿病患者,如果收缩压在130~140mmHg,服不服降压药?

对于糖尿病患者,如果收缩压在130~140mmHg,服不服降压药?

2017年美国心脏病学会/美国心脏协会(ACC/AHA)高血压指南推荐,糖尿病高血压患者启动降压药的门槛是130 mmHg。

但南方医科大学Wang S等进行的Meta分析显示,收缩压在130~140 mmHg的糖尿病患者使用降压药物治疗,可能得不偿失,不仅血管和肾脏无获益,而且不良事件风险还增加。

研究显示,收缩压在130~140 mmHg的糖尿病患者启动降压,并未降低主要血管事件的发生率(RR=1.01,95%CI:0.93~1.10),而且在亚组分析和敏感性分析中是一致的。

此外,降压治疗也没有降低心肌梗死风险、脑卒中风险、心衰风险以及白蛋白尿风险、终末期肾病风险、心血管死亡和全因死亡风险。



除了无任何获益外,还可能增加严重不良事件的风险(RR=2.00,95%CI:1.33~3.01)和低血压风险(RR=5.30,95%CI:0.99~28.40)。

研究者指出,这提示可能不建议糖尿病患者收缩压在低于140 mmHg时开始降压。

对于2017年美国新指南,其中多采纳SPRINT研究的事后分析,但其中纳入的并非糖尿病患者,而是糖尿病前期患者,二者有所差异。

这项研究共纳入6项试验21574例糖尿病患者。
