Rationale and design of a randomized trial of automated hovering for post-myocardial infarction patients: The HeartStrong program

Our randomized controlled trial of the HeartStrong program will provide an evaluation of a state-of-the-art behavioral economic intervention with a number of important pragmatic features. These include a tailored intervention responding to patient activity, streamlining of consent and implementation processes using new technologies, outcomes centrally important to patients, and the ability to implement rapid-cycle innovation.
