The goal of this clinical trial is to determine if a behavioral intervention can increase attendance at cardiac rehabilitation (CR) after secondary/type 2 myocardial infarction in adult patients. The main question it aims to answer is:
* Does the ATTEND-CR intervention increase attendance at ≥1 CR exercise session within 140 days of randomization?
* Does the intervention increase completion of ≥12 CR exercise sessions within 140 days of randomization?
Researchers will compare participants receiving the ATTEND-CR intervention (clinician notifications and a motivational interviewing participant phone call) to usual care to see if attendance and completion of CR improve.
Participants:
* Clinicians will receive informational messaging regarding CR and the referral process
* Participate in a motivational interviewing phone call (intervention group only)
* Have follow-up assessments via telephone and electronic health record (EHR) review to track CR attendance, clinical events, and health outcomes
