Circulation:不同去肾神经方法治疗顽固性高血压

难治性高血压是指联合服用3种或以上合适剂量的抗高血压药物(其中一种为利尿剂),仍然无法控制的高血压。

难治性高血压是指联合服用3种或以上合适剂量的抗高血压药物(其中一种为利尿剂),仍然无法控制的高血压。肾交感神经活动是血压维持和升高的重要环节,肾交感神经的激活对高血压的发生及发展具有重要作用,其主要机制为影响肾脏血管收缩、增加肾素释放和加强水钠重吸收。肾交感神经射频消融术对难治性高血压患者具有肯定的降压效果。德国莱比锡大学心脏中心的Karl Fengler等人进行了一项头对头的比较研究(RADIOSOUND-HTN研究),观察不同的去肾神经技术对于顽固性高血压的疗效。研究者将顽固性高血压患者以1:1:1的比例随机分到:1)肾主动脉射频消融RDN,2)肾主动脉、侧支和附件的射频消融RDN,或3)基于血管内超声能源的RDN。主要终点是3个月白天动态收缩压(ABPM)的变化。该研究在2015年6月至2018年6月,共招募了120名患者(平均年龄64±9岁,白天平均血压153/86±12/13mmHg)。其中39例随机分到肾主动脉射频消融术,39例随机分到肾主动和侧支射频消融,42例随机分到超声RDN。各组之间的基线日间血压、临床特征和治疗方法均衡。在3个月时,整个队列患者的白天动态收缩压下降

顽固性高血压是一种特殊类型的高血压,在应用包括利尿剂在内的3种或以上的足量降压药血压仍难以达标或至少需4种降压药血压才能达标,可能导致严重的靶器官损伤和心血管风险,治疗十分棘手[1]。近年来国外已有前瞻性队列研究和随机对照研究表明[2-4],经导管射频消融肾交感神经术(renal sympathetic denervation,RDN)对于部分顽固性高血压患者具有显著持久的降压作用,且很少发生
