Nonadherence to beta blockers, statins, or angiotensin-converting enzyme inhibitors is common (21%-29%) among patients with coronary artery disease (CAD). Patients who do not adhere to their medication regimens are at increased risk of mortality, cardiovascular hospitalizations, and revascularization procedures; thus, medication nonadherence should be a target for quality improvement interventions to maximize the outcomes of CAD patients.
