The goal of this observational study is to provide a better understanding of medical practice for heart failure management based on real-world data, collected both across Europe and the rest of the world, using robust methodology and representativeness within each country.

Standard management of patients will be the diagnostic and therapeutic interventions routinely performed in each center for patients presenting with signs and symptoms of chronic/acute heart failure.

Inclusion Criteria:

Adult patients with chronic or acute Heart Failure (HF), regardless of ejection fraction, either:

• Outpatient with chronic HF (including first-time diagnosis), according to the clinical judgment.

OR

• Patients admitted to hospital or presenting to Emergency Department or Acute out-patient care for acute HF for whom an IV (diuretics, inotropes, vasodilators) or mechanical therapy for HF (mechanical circulatory support) is administered.

Exclusion Criteria:

• Age <18 years
• Patients unwilling to consent (or patient's legally authorized representative unwilling to consent, if the patient is unable to consent).

The study population is all consenting patients seen in the outpatient clinic for chronic HF and all consenting patients admitted for acute HF in the study center as their standard medical care.
