About this trial
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.

Primary outcomes
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 Two different definitions of adherence are used: * 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. * A 80% threshold is used. If \>80% of the prescribed heart failure drugs were detectable in urine, the patient was characterized as "adherent." Otherwise, the patient was considered to be "nonadherent."
Secondary outcomes
Patients-related factor with impact on adherence (anxiety and depression)
Measurement of anxiety and depressions via one questionnaire with two subscales (Hospital Anxiety and Depression Scale- German version= HADS-D; Two subscales HADS-A (anxiety) and HADS-D (depression), each with 7 items; this results in two total scores for the HADS-A (anxiety) and HADS-D (depression) scales with value ranges from 0 - 21; higher values indicating depression or anxiety; 0-7 unremarkable, 8-10 suspicious, \>10 conspicuous)
Patients-related factors with impact on adherence (social support)
Measurement of social support via one questionnaire (ENRICHD Social Support Instrument German version= ESSI-D; 5 items; total score 5-25; higher values indicating better social support)
Patients-related factor with impact on adherence (dementia)
Measurement of dementia via one questionnaire (Demtect; Total score= 0-18; 0-8= Suspected dementia; 9-12= Mild cognitive impairment; 13-18= Cognitive powers appropriate for subject's age)
