Adherence to ESC guideline-recommended medications over a 36-month follow-up period after hospitalization for heart failure: Results from the EPICAL2 cohort study.

Adherence to guideline-recommended medications while being hospitalized is of great importance because prescriptions are quite stable over time after discharge. HFrEF patients are most often older, with various comorbidities, such as chronic kidney disease or asthma/COPD, which importantly limit physicians' ability to prescribe recommended drugs, leading to suboptimal adherence to guidelines.
