To analyze the age-specific temporal trends, in-hospital outcomes and readmissions for acute heart failure (HF). There is a paucity of data on the age-specific differences in the trends and outcomes of hospitalizations with acute HF. The National Inpatients Sample database years 2002–2016 and the National Readmissions Database years 2013–2016 were used to identify primary hospitalizations for acute HF. We analyzed the age-specific temporal trends, in-hospital outcomes, and readmissions for acute HF. The annual rate of hospitalizations for acute HF declined from 456 per 100,000 people in 2002 to 356 per 100,000 people in 2016 (Ptrend 34 years). This nationwide contemporary analysis demonstrated a decline in the annual rates of hospitalizations with acute HF across all age categories except those aged 18–44 years. There was a reduction in rates of in-hospital mortality among middle-aged and older patients, but not in those aged 18–34. In-hospital mortality exhibited a dichotomous relationship with age. There was an inverse relationship between age and 30-days HF readmissions. •The frequency and in-hospital mortality of acute HF hospitalizations declined among all age groups, except younger patients.•In-hospital mortality exhibited a dichotomous relationship with age.•There was an inverse relationship between age and 30-days HF readmissions.•Future studies are warranted to explore primary and secondary preventive measures for younger patients with acute HF.
