Adherence to Medication in Patients With Acute Decompensated Heart Failure: a Cross-sectional Study at the Emergency Department (ADHF-ED= Adherence to Medication in Patients With Acute Decompensated Heart Failure at the Emergency Department)
Every day, patients present to emergency department due to acute heart failure. There are many causes for decompensation. One possible cause is a lack of adherence to heart failure medication (prognosis-improving medications and diuretics). The aim of this study is to directly measure adherence in patients with acute heart failure (gold standard of adherence measurement using liquid chromatography coupled to high-resolution mass spectrometry= LC-HRMS/MS) at the emergency department. Questionnaires are used to investigate possible factors influencing adherence.
• age ≥18 years of age
• known chronic heart failure irrespective of ejection fraction (heart failure with reduced, mildly reduced, or preserved ejection fraction)
• requirement of intravenous diuretics (outpatient or stationary treatment)
• stable heart failure medication \>2 weeks
• ≥1 sign of volume overload (peripheral edema, jugular venous distension, pulmonary rales, ascites, or demonstration of pulmonary venous congestion on chest X-ray)
• elevated natriuretic peptides (N-terminal pro brain natriuretic peptide= nt-pro-BNP ≥125 pg/ml)
