Impact of readmissions on octogenarians with heart failure with preserved ejection fraction: PURSUIT‐HFpEF registry

Abstract Aims Heart failure (HF) readmissions with preserved ejection fraction (HFpEF) are increasing in the elderly, which is a major socioeconomic problem. We investigated the clinical impact of HF readmissions (HFR) on octogenarians with HFpEF. Methods and results We enrolled consecutive octogenarians (≥80 years old) from June 2016 to February 2020 in PURSUIT‐HFpEF registry. We divided them into HFR group readmitted for HF during the follow‐up period and non‐HF readmission (non‐HFR) group. We evaluated the impact of HFR on all‐cause mortality, cardiac death, and quality of life (QOL). Additionally, we evaluated the factors at discharge correlated with HFR. HFR group comprised 116 patients (21.4%). Among all‐cause deaths, 40 patients suffered cardiac deaths (48.2%). The Kaplan–Meier analysis revealed a similar prognosis between HFR and non‐HFR groups as well as similar incidences of HF deaths. The QOL scores had significantly deteriorated by 1 year later in the HFR group (0.71 ± 0.19 vs. 0.59 ± 0.21, P
