The study is sponsored by the National Heart, Lung, and Blood Institute, which is part of the National Institutes of Health. We expect to enroll 400 subjects into this study. We will be recruiting research participants that are finishing or will finish cardiac rehabilitation soon. Participants belong to one or more groups of people who are less often studied in cardiac rehabilitation research, may have less access to a formal cardiac rehabilitation maintenance program, or they may especially benefit from additional support after cardiac rehabilitation ends. The main purposes of this study are to evaluate which treatments work the best after cardiac rehabilitation, which order to deliver the treatments in, and which treatments are as minimally burdensome as possible while still working well. This study will make two comparisons (one comparison between a set of low-intensity interventions and another between a set of higher-intensity interventions) to determine which produces the best behavioral adherence immediately after Phase II (outpatient) cardiac rehabilitation

We will first test which of two automated online interventions (\[A\] a low-intensity text-messaging intervention of 3 weekly sets of text messages focused on encouragement and reminders about the key health behaviors for 2 months, or \[B\] a fully automated 2-month online program modeled on our previous research, consisting of interactive lessons, self-monitoring, and tailored feedback) serves as the best first-line intervention. The second test is which of two home-based cardiac rehabilitation (CR) maintenance interventions produces the best outcomes for non-responders to the initial interventions. Those who do not respond to the low-intensity interventions will be randomized to receive 3 months of either (C) low-intensity home-based CR, consisting of education and exercise prescription, or (D) high-intensity home-based online CR that includes education and exercise prescription plus case management. Adherence to the 3 targeted cardioprotective behaviors will be measured after Phase II completion (baseline), the initial low-touch interventions (at Month 3), after 3 more months of continued or new interventions (at Month 6), and 6-months of no-treatment follow-up (at Month 12). The primary outcome will be adherence to the 3 cardioprotective behaviors (physical activity, weight management, and medication adherence) measured together in the Sequential, Multiple Assignment, Randomized Trials (SMART) decision rule (responder status) and individually. Exploratory outcomes will be death, rehospitalization, and quality of life. The specific aims of this study are to: (1) Compare the 2 least intensive, online, intervention options (text message versus an automated online program) to determine which produces the best behavioral adherence immediately after Phase II CR; (2) Determine whether low- or high-intensity home-based CR (i.e., with or without case management) produces superior behavioral adherence after failure of initial low-intensity online intervention; (3) Finalize the adaptive treatment based on the results of the first two aims; and (4) \[Exploratory Aim\] Conduct a moderators analysis to test for differential effects within specific participant groups.
