A Web-Based Program Improves Physical Activity Outcomes in a Primary Care Angina Population: Randomized Controlled Trial

94 adults with a confirmed diagnosis of stable angina recruited from 9 primary care general practitioners, mean age ~66, ~75% male, UK-based. Key exclusions: unstable angina, significant cardiac arrhythmia, comorbidities preventing physical activity, severely anxious/depressed, or conventional cardiac rehabilitation within the previous year.

A 6-week Web-based cardiac rehabilitation program ('ActivateYourHeart') delivered via the Internet after an initial face-to-face introduction. The program included individualized goals for physical activity, diet, emotions, and smoking, an online exercise diary, and communication with cardiac rehabilitation nurses via email or synchronized chat room.

Treatment as usual from general practitioner, consisting of being placed on a coronary heart disease register and attending an annual review.

Change in daily average step count at 6-week follow-up, measured using a Sensewear Pro 3 accelerometer worn for 2 weekdays (12 hours per day).surrogate
