Medication nonadherence following myocardial infarction (MI) is prevalent and increases the risk of recurrent cardiovascular events. Socioeconomic factors including medication cost, financial insecurity, and poor health literacy are associated with nonadherence. We present a patient with a history of recurrent MI who was nonadherent due to socioeconomic challenges. Our patient subsequently developed ST-elevation MI secondary to in-stent thrombosis. This case illustrates the importance of pre-discharge screening for barriers to adherence.
