Key result
Low medication adherence affects ~80% of heart failure patients, driven by sociodemographic and clinical factors.
Why the study?
Despite effective pharmacological therapies for HF, low treatment adherence remains the leading cause of rehospitalizations and worse outcomes, warranting assessment of adherence and its determinants.
Population
Patients with HF followed at cardiology outpatient clinics of a specialized hospital
Design
Single-center cross-sectional observational study

High nonadherence in HF outpatients links to identifiable predictors; observational data leave open whether targeting them improves outcomes.
Cross-Sectional (n=200)
No
A high prevalence of low medication adherence (79.6%) was observed among heart failure outpatients, driven by polypharmacy, lower education, and HFimpEF status.
Jesus et al. (2026) conducted a cross-sectional in Heart failure (n=200). Sociodemographic and clinical factors was evaluated on Low medication adherence according to the Brief Medication Questionnaire (BMQ). Among patients with heart failure, 79.6% exhibited low medication adherence, which was independently predicted by factors including unmarried status, lack of prior acute coronary syndrome, lower education, polypharmacy, and improved ejection fraction.
