This study aimed to examine the prospective associations between total physical activity, leisure-time physical activity (LTPA), and domestic and work-related physical activity (DWPA) involving heavy physical labor, with all-cause mortality in patients with cardiovascular disease (CVD). A 7-year follow-up cohort design was used based on the data from the Taiwan 2005 National Health Interview Survey, which was linked to the 2005 to 2012 Taiwan National Health Insurance claims data. Multivariable Cox proportional hazard models were utilized to assess the associations between physical activity and all-cause mortality in 2,370 patients with CVD. Participants who achieved a volume of all physical activities of ≥1,000 kcal/week experienced lower risks of all-cause mortality than those who achieved less. Additionally, an inverse relation between LTPA and all-cause mortality was observed. Furthermore, participants who reported exertions (1 to 999 kcal/week) in DWPA had the lowest risk of all-cause mortality. This study provides evidence that patients with CVD who achieve at least a moderate volume of physical activity reduce their mortality risk. It also reveals that both LTPA and DWPA may be important contributors to the reduced risk of premature death among this clinical population.
本研究旨在探讨心血管疾病 (CVD) 患者的总身体活动、休闲时间身体活动 (LTPA) 以及涉及重体力劳动的家务和工作相关身体活动 (DWPA) 与全因死亡率之间的前瞻性关联。该研究采用了基于台湾 2005 年全国健康访谈调查数据的 7 年随访队列设计，并与 2005 年至 2012 年台湾全民健康保险理赔数据进行了关联。多变量 Cox 比例风险模型用于评估 2370 名 CVD 患者的身体活动与全因死亡率之间的关联。与活动量较少的患者相比，达到每周≥1000 千卡总身体活动量的患者全因死亡率风险较低。此外，还观察到 LTPA 与全因死亡率之间呈负相关。此外，报告 DWPA 中有（1 至 999 千卡/周）用力活动的参与者全因死亡率最低。本研究提供了证据表明，达到至少中等身体活动量的 CVD 患者可以降低其死亡风险。它还表明，LTPA 和 DWPA 可能是降低该临床人群过早死亡风险的重要因素。
