Tailored digital support to cut sedentary time in long-term cardiac rehab

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This randomized trial evaluates a 6-month tailored behavioural intervention added to standard long-term cardiac rehabilitation. The intervention uses individualized counselling, digital prompts, smartphone self-monitoring, and educational resources to reduce sedentary behaviour. Primary outcome is objectively measured daily sedentary time with activPAL4. The study aims to determine if integrating digital health tools and tailored coaching can sustain lifestyle changes and improve cardiovascular-related health outcomes in this population.
