Prognostic Value Of Short-Term Follow-up Biomarkers After Discharge In hOspitalized Patients With Acute Heart Failure

Inclusion Criteria: the diagnosis of Heart failure requires the following 1. heart failure with reduced ejection fraction ( A 'reduced' ejection fraction (EF) defined as EF \<40%): the presence of symptoms and/or signs of HF 2. heart failure with preserved ejection fraction ( A 'preserved' EF defined as EF≥ 40%) requires the all of the followings: a) the presence of symptoms and/or signs of HF b) elevated levels of natriuretic peptides (defined as B-type natriuretic peptide (BNP) \>100pg/ml and/or N terminal B-type natriuretic peptide (NT-proBNP) \>300pg/ml) c) any structural heart disease (left atrial volume index ≥ 34 mL/m2, left atrial dimension ≥ 50 mm, posterior or septal wall thickness ≥ 11mm) Exclusion Criteria: * any severe condition limiting life less than 3 months * the patient is not ready to contact by telephone at the end of the study
