对于植入式心脏转换器除器 (ICD) 接受者来说,有氧运动是安全的,显著改善心血管性能. 这种以家庭为基础的计划并没有增加ICD冲击或住院病例,这挑战了以前的担忧.
科学领域:
- 心脏病学 心脏病学
- 运动生理学 运动生理学
- 医疗器械 医疗器械
背景情况:
- 有氧运动对健康有好处,但由于担心运动引起的心律失常,植入式心脏转移器除器 (ICD) 的患者经常避免进行这种运动.
- 这项研究前性地评估了针对ICD患者的家庭有氧运动计划.
研究的目的:
- 评估家庭有氧运动计划对ICD接受者的有氧能力的影响.
- 通过监测ICD冲击和住院病例来确定该炼计划的安全性.
主要方法:
- 160名ICD患者被随机分配到一个为期8周的家庭炼计划 (每天走路1小时,5天/周),然后进行维护或通常的护理.
- 峰值氧气消耗在基线,第8周和第24周被测量.
- 通过日志,心率记录和ICD审讯来监测坚持和不良事件.
主要成果:
- 运动组在8周 (26.7±7.0对比23.9±6.6毫升/公斤/分钟,P=0.002) 和24周 (26.9±7.7对比23.4±6.0毫升/公斤/分钟,P<0.001) 显著增加了峰值氧气消耗.
- 在这两组中,ICD冲击不常见 (在运动中4次,在常规护理中8次).
- 在运动和通常护理组之间,没有观察到住院或死亡的显著差异.
结论:
- 处方的家用有氧运动对于ICD患者来说是安全的.
- 这种运动干预显著提高了ICD接受者的心血管性能,而不会增加冲击或住院等不良事件.

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
