老年人舒张压70~80 mmHg更合适!广东省医冯颖青等研究称:此范围内脑卒中风险很低

2019-12-15 岱西 中国循环杂志

对于≥60老年高血压患者,血压低一点更能预防脑卒中?近日,广东省心血管病中心、广东省人民医院冯颖青等进行的研究显示这部分患者舒张压或控制在70~80 mmHg最适宜,高于或低于这个范围,患者脑卒中风险均会增加。研究显示,与舒张压控制在70~79.9 mmHg的老年高血压患者相比:舒张压<70mmHg增加32%的脑卒中风险;80~89.9 mmHg增加50%的脑卒中风险;而≥90mmHg则增加

对于≥60老年高血压患者,血压低一点更能预防卒中

近日,广东省心血管病中心、广东省人民医院冯颖青等进行的研究显示这部分患者舒张压或控制在70~80 mmHg最适宜,高于或低于这个范围,患者脑卒中风险均会增加。

研究显示,与舒张压控制在70~79.9 mmHg的老年高血压患者相比:

舒张压<70mmHg增加32%的脑卒中风险;

80~89.9 mmHg增加50%的脑卒中风险;

而≥90mmHg则增加131%的脑卒中风险。

以上结果,是研究者在考虑了年龄、性别、体重指数、收缩压、空腹血糖、总胆固醇、甘油三酸酯、高密度脂蛋白胆固醇、低密度脂蛋白胆固醇、估算肾小球滤过率、糖尿病或冠状动脉疾病病史、吸烟、饮酒、使用降压药物、使用抗血小板药物或他汀类药物等后的结果。

对于强化降低舒张压脑卒中风险高的原因,目前认为,强化降低舒张压会导致亚临床心肌损害,重要脏器灌注不足、自动调节受损,最终导致心脑血管转归不良。

这项研究共纳入3315例≥60老年高血压患者,44.49%为男性,平均年龄71.4岁。中位随访5.5年期间,206例罹患缺血性脑卒中。
