Acute Heart Failure (AHF) refers to rapid or gradual onset of symptoms and/or signs of heart failure, severe enough for the patient to seek urgent medical attention.
Commonly leads to an unplanned hospital admission or an emergency department visit.
AHF is a leading cause of hospitalisations in subjects aged >65 years and is associated with high mortality and rehospitalisation rates.
In-hospital mortality ranges from 4% to 10%.
Post-discharge 1-year mortality can be 25-30% with up to more than 45% deaths or readmission rates.
