JAHA:房颤负荷与活动量呈负相关性

2018-11-30 MedSci MedSci原创

近期有研究显示房颤患者的活动量与心血管死亡和发病风险呈相关性。本研究的目的旨在评估房颤的日负荷对接受肺静脉隔离患者活动量的影响。本研究纳入了DISCERN AF临床研究中的对象,所有对象均有心脏监测仪记录每天的房性心动过速和房颤(AT/AF)与相应的活动量水平。最终纳入分析了50例患者,每例患者平均有887次记录。结果显示,消融后的每日AT/AF范围为0-1440min,每日活动量的最小时间和最大

近期有研究显示房颤患者的活动量与血管死亡和发病风险呈相关性。本研究的目的旨在评估房颤的日负荷对接受肺静脉隔离患者活动量的影响。

本研究纳入了DISCERN AF临床研究中的对象,所有对象均有心脏监测仪记录每天的房性心动过速和房颤(AT/AF)与相应的活动量水平。最终纳入分析了50例患者,每例患者平均有887次记录。结果显示,消融后的每日AT/AF范围为0-1440min,每日活动量的最小时间和最大时间分别是0min和600min。活动量与房颤的复合呈反相关(P<0.001; 95% Cl, 0.01–0.04),房颤时间超过500min后日活动量呈进展性下降,房颤时间超过1000min后日活动量急剧下降。另外,在多变量调整分析后,AT/AF负荷与活动量的负相关性依旧存在(P =0.02; 95% Cl, -003 to 0.04)。

研究结果显示,在接受房颤消融术后的患者中,日活动量与房颤的负荷呈明显的负相关性。
