The clinical characteristics, initial presentation, management, and outcomes of patients hospitalized with new-onset (first diagnosis) heart failure (HF) or decompensation of chronic HF are poorly understood worldwide. REPORT-HF is a global, prospective, and observational HF disease registry designed to characterize patient trajectories longitudinally during and following an index hospitalization for acute HF.

Inclusion Criteria:

Patients at least 18 years old, or older for those countries where the adult age is above 18 years of age, hospitalized with a primary diagnosis of acute heart failure.

Exclusion Criteria:

1-Concomitant participation in any/a clinical trial with any investigational treatment (for any sponsor).

2. Use of investigational drugs within 5 half-lives of enrollment, or until the expected pharmacodynamic effect has returned to baseline, whichever is longer.

Enrollment of adult patients hospitalized with a primary diagnosis of acute Heart Failure (HF), i.e. new-onset (first diagnosis) HF or decompensation of chronic HF
