 Background: In patients who have had a myocardial infarction MI and coronary disease, guidelines recommend cardiac rehabilitation services and the long-term use of cardiac medications to reduce the risk of recurrent cardiovascular events. Adherence to these recommendations substantially reduces morbidity and mortality post-MI. However, for a variety of patient, provider, and system-level reasons, adherence to cardiac medications declines to approximately 50 by 12 months. Likewise, only 30-40 of patients participate in cardiac rehabilitation. Thus, interventions to increase secondary prevention treatment adherence are urgently needed.
