深度脑刺激技术可帮助控制高血压

英国布里斯托尔大学等机构的研究人员在新一期美国《神经病学》(Neurology)杂志上报告说,这名患者现年55岁,因为一次中风而被查出患有高血压,但降压药对他并没有明显效果。于是研究人员尝试了一种名为“深度脑刺激”的技术,就是在大脑中植入一个类似心脏起搏器的装置,它可以持续对大脑中一些与控制血压有关的部位发出电流刺激,以此帮助控制血压。

结果显示,在植入这个装置后的3年跟踪观察期内,患者血压得到良好控制。为证明是该装置起到了降血压效果,研究人员还试验性地关闭过几次该装置,结果血压很快升高,在重新开启装置后血压又回落到正常水平。

研究人员说,高血压常会引起中风或心脏病等严重后果,而且对于约十分之一的高血压患者来说,降压药都不易起作用或是患者因其他原因不能服用降压药。这次研究展示了一种不同于药物的降血压手段,对这部分高血压患者是个好消息。研究人员今后计划通过大规模临床试验来进一步验证这种电流刺激装置的可靠性。
