≥80岁老人减降压药不影响血压达标!JAMA随机对照研究

2020-06-09 xujing 中国循环杂志

JAMA杂志发表的一项随机对照研究提示,对于应用2种以上降压药物的80岁以上的老老年患者,减少1种降压药物仍能有效控制血压。

JAMA杂志发表的一项随机对照研究提示,对于应用2种以上降压药物的80岁以上的老老年患者,减少1种降压药物仍能有效控制血压。

这项随机、无盲、非劣效性研究在英国69个初级保健中心进行。纳入534例年龄在80岁以上患者,收缩压低于150 mmHg,均应用至少2种降压药物。初级保健医生认为他们适合减少药物治疗。

按1:1的比例分配到降压药物减少组(减少1种药物,n=282)或不改变药物数量的常规治疗组(为对照组,n=287)。

结果显示,12周随访时,药物减少组中,收缩压低于150 mmHg的患者比例为86.4%,对照组为87.7%(调整后相对危险度为0.98),这一差异符合相对危险度为0.90的非劣效边缘。

次要结果包括参与者维持药物减少的比例以及血压、虚弱、生活质量、不良反应和严重不良事件的差异。

在7个预定的次级终点中,5个没有显着差异。

在12周时,187例(66.3%)患者持续服药减少。降压药物减少组平均收缩压的变化比对照组高3.4 mmHg。

药物减少组12例(4.3%)患者和对照组7例(2.4%)患者报告了至少1例严重不良事件(调整后的RR=1.72)。

可见,对于接受多种降压药物治疗的老年患者中,与常规治疗相比,减少药物数量在12周时对收缩压的控制并无影响,但仍需进一步研究长期的临床结果。
