JAHA:植入装置测量的体力活动可预测房性心律失常和患者预后!

2018-02-26 xing.T MedSci原创

由此可见,在植入ICD的心衰患者中,无论患者的基线特征如何,低水平的PA与房性心律失常的风险有较高的相关性。此外,较低的每日PA可以预测患者死亡或心衰住院。

近日,心血管疾病领域权威杂志JAHA上发表了一篇研究文章,研究人员旨在明确日常体力活动(PA),通过植入装置(加速度传感器)测量,是否与植入型心律转复除颤器(ICD)心衰患者长期随访期间的房性心律失常风险相关。

在植入ICD后30天至60天期间研究人员根据植入装置记录了受试者每天的平均PA,并将研究对象分为2个人数相等的组别(PA截止点:3.5小时/天)。研究人员采用倾向评分匹配法比较了2个同等大小的具有相似特征的较低和较高活动度的患者队列。该研究主要终点是发生首次持续时间≥6分钟快速房性心律失常(AHRE)的时间。次要终点为:首次≥6小时的AHRE的时间,首次≥48小时的AHRE的时间和死亡或因心衰住院的复合终点。

研究人员对770例(65±15岁、66%为男性,左室射血分数为35±12%)患者进行了为期25个月的远程监测。PA≥3.5h/d与≥6分钟的AHRE相对风险降低38%相关(72个月累计生存率:75% vs. 68.1%;P=0.025),并且≥6小时的AHRE、≥48小时的AHRE和死亡或心衰住院复合终点风险降低(均有P<0.05)。

由此可见,在植入ICD的心衰患者中,无论患者的基线特征如何,低水平的PA与房性心律失常的风险有较高的相关性。此外,较低的每日PA可以预测患者死亡或心衰住院。
