P value for comparison of adherent and nonadherent groups
a
Patients were classified as adherent when 88% or above of days they took correct dose.
Patients were classified as nonadherent if less than 88% of days they took correct dose. Data are presented as means ± SD, or N (%); ACEI = angiotensin-converting-enzyme inhibitor; BB = beta blocker; LVEF = Left Ventricular Ejection Fraction; NYHA = New York Heart Association
