['Medication non-adherence is a significant contributor to suboptimal control of blood pressure and lipids.', 'This study determined if having a paid and/or family caregiver was associated with medication adherence in patients hospitalized for cardiovascular disease.', 'Consecutive patients admitted to the cardiovascular service at a university medical center who completed a standardized questionnaire about medication adherence and caregiving (paid/professional or family member/friend) were included in this analysis (N = 1,432; 63 % white; 63%male).', 'Among cardiac patients, 39 % reported being prescribed ≥ 7 different medications, and one in four reported being non-adherent to their medication(s). Participants who reported having/planning to have a paid caregiver were 40 % less likely to be non-adherent to their medications compared to their counterparts. The association remained significant after adjustment for demographic confounders and comorbid conditions (OR = 0.49; 95 %CI = 0.29-0.82).'] Is medication adherence associated with having a caregiver among cardiac patients?
