短期CPAP心肌交感神经功能

加拿大一项研究表明，在同时伴射血分数降低性心衰(HFrEF)和阻塞性睡眠呼吸暂停(OSA)的患者中，短期持续正压通气(CPAP)可改善心肌交感神经功能，并有可能在严重OSA患者中改善心肌效能。论文于7月3日在线发表于《循环》(Circulation)杂志。 此项研究共纳入45例同时伴有HFrEF和OSA的患者，并随机给予(22例)或不给予(23例)短期CAPA治疗。在CAPA治疗前和治疗后6～8

加拿大一项研究表明，在同时伴射血分数降低性心衰(HFrEF)和阻塞性睡眠呼吸暂停(OSA)的患者中，短期持续正压通气(CPAP)可改善心肌交感神经功能，并有可能在严重OSA患者中改善心肌效能。论文于7月3日在线发表于《循环》(Circulation)杂志。

此项研究共纳入45例同时伴有HFrEF和OSA的患者，并随机给予(22例)或不给予(23例)短期CAPA治疗。在CAPA治疗前和治疗后6～8周实施超声心动图和HED PET评估。计算心肌效率估计值工作代谢指数(WMI)，并利用HED保留指数计算突触前交感神经功能。

结果显示，与非CAPA组患者相比，CAPA组患者的HED保留指数显著升高(P=0.003)。两组患者的WMI无显著变化。然而，在OSA更为严重的患者中(呼吸暂停低通气指数>20/小时)，CPAP可显著升高WMI和收缩压(P<0.05)。
