Results of a large study indicate that nearly one-third of patients are no longer persistent with prescribed medications when assessed at 6 months after an acute myocardial infarction (AMI). The most common reasons cited by AMI patients for discontinuing medication were side effects and physician instruction (57%). African-American race, older age, atrial fibrillation, dialysis, and depression decreased the likelihood of medication persistence among AMI patients.
