Brief Summary

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.

Acute Decompensated Heart Failure

Acute Decompensated Heart Failure; Adherence; Emergency department

Outcome Measures

Primary Outcomes (1)

• Adherence to heart failure medication

  Directly measured adherence rates (measurement of drug levels or metabolites in body fluids via toxicological analysis) of patients with acute heart failure at the emergency department \- If all prescribed drugs/metabolites for the treatment of heart failure were detectable in urine, the patient is "adherend". If 1 or at least 2 prescribed drugs were nondetectable in urine, the patient was classified as "partially adherend" and "non-adherend", respectively.

  1 day (cross-sectional)

Secondary Outcomes (3)

• Patients-related factor with impact on adherence (anxiety and depression)

  1 day (cross-sectional)

• Patients-related factors with impact on adherence (social support)

  1 day (cross-sectional)

• Patients-related factor with impact on adherence (dementia)

  1 day (cross-sectional)

Eligibility Criteria

• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)
