Adherence to a novel oral anticoagulant among patients with atrial fibrillation.
The researchers examined adherence and persistence to dabigatran among adults with atrial fibrillation. Among those using dabigatran alone (n = 2,713), 41 percent were nonadherent with therapy, and 32 percent had gaps of 60 days or greater. Among those observed for 9 months who used dabigatran alone, rates of nonadherence were 47 percent, whereas 48 percent discontinued therapy during follow-up.

Association of patient enrollment in Medicare Part D with outcomes after acute myocardial infarction.
The researchers investigated whether enrollment versus nonenrollment in Medicare's prescription drug plan (Part D) is associated with better outcomes after acute myocardial infarction (AMI). They found that only half of Medicare-insured patients with AMI were enrolled in Part D by hospital discharge, and their 30-day and 1-year adjusted outcomes did not differ substantially from nonenrollees.

Factors affecting medication adherence trajectories for patients with heart failure.
The researchers examined the relationship between patient characteristics and medication adherence trajectories for patients with congestive heart failure (CHF). They found that age, region, education, smoking, and race were all significantly associated with the likelihood of belonging to a particular trajectory (low, increasing, decreasing, and high adherence). Nonwhites were less likely to be in the high adherence group, and smoking was more common in the low adherence group (22 percent) than in the high group (10 percent).

Medication non-adherence after myocardial infarction: an exploration of modifying factors.
The purpose of this study was to identify demographic and patient characteristics, medical comorbidities, psychosocial factors, and health belief-related factors associated with medication non-adherence among patients with known cardiovascular disease. They found that worry about having a stroke, higher life chaos, and younger age were all significantly associated with self-reported medication nonadherence in patients with cardiovascular disease and a history of myocardial infarction.
