Characteristics, Treatment, and Prognosis in Octogenarian and Older Patients With Acute Heart Failure in Japan - Prospective Observational Study on Acute Pharmacotherapy and Prognosis in Management of Acute Heart Failure (POPEYE-AHF Registry).

BACKGROUND

The number of older people in Japan is increasing more quickly than in other countries; with this aging of society, the number of elderly patients hospitalized for acute heart failure (HF) is also increasing. The treatment and prognosis of acute HF may be changing, but there are insufficient recent data, especially for octogenarian and older patients.

METHODS AND RESULTS

This study investigated the characteristics and treatment of acute HF patients in Japan. From 2018 to 2020, 1,146 patients from 7 Tokai area hospitals were followed for at least 1 year. The mean age was 78 years. Compared with patients aged <80 years, those aged ≥80 years were more likely to be female (57.4% vs. 34.2%), have a lower body mass index (22.2 vs. 24.9 kg/m), and have HF with preserved ejection fraction (43.1% vs. 21.4%), and less likely to have HF with reduced ejection fraction (38.9% vs. 61.7%). During hospitalization, 6.5% died. After discharge, patients faced high risks of rehospitalization for HF and death (27.6 and 14.2 per 100 patient-years, respectively). Notably, prescription rates of HF medications have declined over time for all patients, but especially for those aged ≥80 years.

CONCLUSIONS

Guideline-directed medical therapy should be provided based on a thorough understanding of an individual's background rather than withheld simply because of clinical inertia due to a patient's advanced age.
