ISC 2014:植入式监测仪可发现不明原因卒中患者的心房颤动

2014国际卒中大会(ISC)上,Richard A. Bernstein博士(美国西北大学)报告的CRYSTAL-AF研究结果显示,对于发生不明原因卒中的患者,使用植入式心脏监测仪的心房颤动(房颤)检出率显著高于标准监测。研究者表示,房颤是卒中最重要的危险因素之一,可通过抗凝治疗预防,监测仪能显著降低卒中复发率。研究入选441例不明原因卒中患者,所有患者在卒中90天内接受至少24小时的标准心脏监

2014国际卒中大会(ISC)上,Richard A. Bernstein博士(美国西北大学)报告的CRYSTAL-AF研究结果显示,对于发生不明原因卒中的患者,使用植入式心脏监测仪的心房颤动(房颤)检出率显著高于标准监测。

研究者表示,房颤是卒中最重要的危险因素之一,可通过抗凝治疗预防,监测仪能显著降低卒中复发率。

研究入选441例不明原因卒中患者,所有患者在卒中90天内接受至少24小时的标准心脏监测,其中一半患者随后使用植入式监测仪持续监测3年。监测仪大小和U盘相似,可于门诊手术室局麻下植入皮下。研究结果显示,和传统监测方法相比,监测仪在6个月~3年内使房颤诊断率提高5~7倍。研究中发现97%的房颤患者接受了抗凝治疗。治疗组患者卒中例数少于对照组,但未达到统计学差异。

Bernstein表示,该植入装置的获益远大于风险,仅有2.4%的装置因并发症被移除,患者未发生远期并发症。“卒中患者房颤若未被发现,很可能因没有接受抗凝治疗而再次发生卒中。”

“对照组共进行了121次心电图,32次Holter和1次事件记录器检查,220例患者在1年内仅发现4例房颤,而植入式监测仪发现29例。这显示目前的房颤检测方法有很大不足。”此外,本研究中植入式监测仪发现房颤的中位时间为84天。Bernstein谈到,“你无法要求患者长期佩戴外置装置。”
