The CardioFit Internet-based expert system was designed to promote physical activity in patients with coronary heart disease (CHD) who were not participating in cardiac rehabilitation.
This randomized controlled trial compared CardioFit to usual care to assess its effects on physical activity following hospitalization for acute coronary syndromes.
A total of 223 participants were recruited at the University of Ottawa Heart Institute or London Health Sciences Centre and randomly assigned to either CardioFit (n = 115) or usual care (n = 108). The CardioFit group received a personally tailored physical-activity plan upon discharge from the hospital and access to a secure website for activity planning and tracking. They completed five online tutorials over a 6-month period and were in email contact with an exercise specialist. Usual care consisted of physical activity guidance from an attending cardiologist. Physical activity was measured by pedometer and self-reported over a 7-day period, 6 and 12 months after randomization.
The CardioFit Internet-based physical activity expert system significantly increased objectively measured (p = 0.023) and self-reported physical activity (p = 0.047) compared to usual care. Emotional (p = 0.038) and physical (p = 0.031) dimensions of heart disease health-related quality of life were also higher with CardioFit compared to usual care.
Patients with CHD using an Internet-based activity prescription with online coaching were more physically active at follow up than those receiving usual care. Use of the CardioFit program could extend the reach of rehabilitation and secondary-prevention services.
CardioFit 网络专家系统旨在促进未参与心脏康复的冠心病患者进行身体活动。
这项随机对照试验将 CardioFit 与常规护理进行比较，以评估其在急性冠状动脉综合征住院后对身体活动的影响。
共在渥太华大学心脏研究所或伦敦健康科学中心招募了 223 名参与者，并将其随机分为 CardioFit 组（n=115）和常规护理组（n=108）。CardioFit 组在出院后收到个性化的身体活动计划，并可访问一个安全的网站进行活动计划和跟踪。他们在 6 个月的时间内完成了五个在线教程，并与运动专家通过电子邮件保持联系。常规护理包括主治心脏病专家提供的身体活动指导。身体活动通过计步器和 7 天自我报告进行测量，在随机分组后 6 个月和 12 个月进行测量。
与常规护理相比，CardioFit 网络身体活动专家系统显著增加了客观测量（p=0.023）和自我报告的身体活动（p=0.047）。与常规护理相比，CardioFit 还提高了心脏病相关生活质量的情感（p=0.038）和身体（p=0.031）维度。
与接受常规护理的患者相比，使用基于互联网的活动处方和在线指导的冠心病患者在随访时更活跃。CardioFit 程序的使用可以扩大康复和二级预防服务的覆盖面。
