Acute decompensated heart failure (ADHF) characterizes patients with worsening HF signs or symptoms, often requiring hospitalization. Patients with persistent symptoms or refractory HF despite optimal oral therapies are classified as stage D by the American College of Cardiology/American Heart Association staging system. Additionally, ADHF patients have symptoms with minimal activity or at rest and thus are most commonly classified as New York Heart Association class III or IV.
