Positive Emotions Following Acute Cardiac Events
Purpose
The focus of this study is to test the efficacy of a 12-week, remotely delivered, positive-psychology-motivational interviewing (PP-MI) intervention, with additional twice weekly text messages for a total of 24 weeks (with interactive, algorithm-driven, goal-focused text messages in the final 12 weeks), compared to post-acute coronary syndrome (ACS) treatment as usual, in a randomized trial of 280 post-ACS patients with low baseline physical activity.

Experimental Positive Psychology + Motivational Interviewing |
Each week, participants in the PP-MI intervention group will complete a PP activity and work towards a physical activity goal, then complete a phone session with a study trainer. Each phone session will include PP and goal setting portions. In the PP portion, the study trainer will (a) review the week's PP exercise, (b) discuss the rationale of the next week's PP exercise through a guided review of the PP-MI manual, and (c) assign the next week's PP exercise. In the goal-setting portion, the trainer will (a) review the participant's physical activity goal from the prior week, (b) discuss techniques for improving physical activity (e.g. tracking activity), and (c) help the participant to set a physical activity goal for the next week. Participants also will receive supplemental text messages throughout the 12 weeks of the intervention and during the initial follow-up period (Week 13-24). |

No Intervention Treatment as Usual |
Participants in the treatment as usual (TAU) arm will not receive any specific intervention, though they will be free to receive any post-ACS treatment. |

Detailed Description
The investigators are proposing a study that will focus on testing the efficacy of a PP-MI intervention, with additional twice text messages for a total of 24 weeks (with interactive, algorithm-driven, goal-focused text messages in the final 12 weeks) in post-ACS patients. The investigators will enroll 280 post-ACS patients, who will take part in either a 12-week intervention (with 24 weeks of supplemental text messages), or receive post-ACS treatment as usual. In this project, the investigators hope to do the following: 1. Examine the efficacy of a 12-week, phone-delivered PP-MI intervention for individuals with ACS on physical activity-related outcomes, as compared to the treatment as usual group. 2. Assess the intervention's impact on psychological (e.g. positive affect), functional (e.g. physical function), and behavioral (e.g. overall adherence) outcomes. 3. Explore the intervention's impact on markers of cardiovascular health (e.g., cardiac biomarkers), as well as major adverse cardiac events/readmissions. Participants will be screened and enrolled during admission for an ACS. They will be provided with a accelerometer to monitor their physical activity for one week prior to their first in-person visit. At their first visit, they will answer questionnaires related to psychological and physical health and functioning, have their blood pressure and weight measured, and provide a fasting blood sample. Upon confirmation of adequate physical activity, participants will be randomized to receive the PP-MI intervention or treatment as usual. Participants in the intervention will be provided a treatment manual, an activity tracker, and other treatment materials. The intervention will be introduced, and the first exercise will be assigned. Following the first in-person visit, participants in the treatment condition will complete twelve weekly phone sessions with a study trainer. The phone sessions primarily will include a review of the prior week's session content and a discussion of the rationale and assignment of the next week's exercise/assignment. Participants in the treatment condition will receive twice weekly text messages throughout the intervention (Weeks 1-12) and initial follow-up period (Weeks 13-24). These messages will focus on the PP activity and physical activity. During Weeks 13-24, participants in the PP-MI condition will engage with twice weekly, automated, interactive text messages related to PP and physical activity. At Weeks 12, 24, and 48, participants will complete follow-up visits. One week prior to these visits, participants will be mailed an accelerometer and will wear it until their study visit. During these study visits, participants will be asked to answer questionnaires related to psychological and physical health and functioning, have their blood pressure and weight measured, and be asked about cardiovascular outcomes, including hospitalizations, cardiovascular procedures, and cardiac-specific hospitalizations. They will also provide a fasting blood sample. Finally, participants will complete phone sessions every 6 months until study end to inquire about hospitalizations and adverse cardiac events.
