BACKGROUND: The CardioFit Internet-based expert system was designed to promote physical activity in @entity1 with @entity301 ( @entity301 ) who were not participating in cardiac rehabilitation. DESIGN: This randomized controlled trial compared CardioFit to usual care to assess its effects on physical activity following hospitalization for @entity1187 . METHODS: A total of 223 @entity1 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. RESULTS: 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 @entity299 health-related quality of life were also higher with CardioFit compared to usual care. CONCLUSIONS: @entity1 with @entity301 using an Internet-based activity prescription with online @entity15285 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.
