The AWARE-Angina study is a cluster randomized trial aimed at evaluating whether routine provider feedback of patients' angina burden and activity level can improve angina control. Patients will wear an activity monitor for 6 months, and their providers will be randomized to receive either monthly feedback or feedback at the end of the study period.

This is a cluster randomized trial of using a wearable activity monitor to enhance communication between patients with recent acute Myocardial Infarction (MI) and their physicians. After IRB approval, each site will be randomly assigned to either the monthly feedback or the end-of-study feedback arm. All participating providers will participate in an accredited webinar discussing the prevalence of post-MI angina, effects of angina on quality of life and outcomes, and the evidence supporting use of available treatment options. The intention of this approach is to develop a similar baseline understanding of angina among the participants so that knowledge gaps do not interfere with the intervention described below.

Patients at each site who meet the eligibility criteria (acute MI within 6 months with documentation of at least single-vessel coronary artery disease, possession of a smartphone) will be approached for consideration of participation. Those who qualify and express interest will provide informed consent to the study procedures.

At the time of enrollment, patient data (including socio-demographic information, medial history and comorbidities, details of the patient's index MI, secondary prevention medications, and anti-anginal medication prescriptions) will be collected by participating sites for each enrolled patient via a paper data collection form and faxed to a secure fax machine at the DCRI. Patients will also complete a brief survey including questions about angina frequency and quality of life.

All patients will receive a wearable activity tracker (WithingsGO) and smartphone-based app (Withings Health mate). Patients will be instructed on how to put on and take off the wearable activity monitor. They will be instructed to wear the activity monitor continuously while awake for the duration of the study. For the next 6 months, the wearable activity monitor will measure daily step count and distance walked. This data will be transmitted continuously via a Bluetooth connection to the smartphone-based app. The activity monitor application will share activity data through Validic with DCRI IT/CDM through a secure Web Portal. Every other week, patients will receive an email with a link to a Qualtrics survey including questions regarding angina frequency, angina severity, use of short-acting nitroglycerin tablets, and whether they had any overnight hospitalizations in the 2 weeks prior. The survey data will be transmitted to the DCRI through Qualtrics. If patients miss 2 or more consecutive Qualtrics surveys, then representatives from DCRI will contact the patient to complete.
