Prognostic significance of the HFAâPEFF score in patients with heart failure with preserved ejection fraction
Abstract Aims The HFAâPEFF score is a part of the stepwise diagnostic algorithm of heart failure with preserved ejection fraction (HFpEF). We aimed to evaluate the prognostic significance of the HFAâPEFF score on the clinical outcomes in patients with HFpEF. Methods and results The Prospective mUlticenteR obServational stUdy of patIenTs with Heart Failure with preserved Ejection Fraction (PURSUITâHFpEF) study is a prospective, multicentre, observational study in which collaborating hospitals in Osaka record clinical, echocardiographic, and outcome data of patients with acute decompensated heart failure with preserved left ventricular ejection fraction (â„50%) [UMINâCTR ID: UMIN000021831]. Acute decompensated heart failure was diagnosed on the basis of the following criteria: (i) clinical symptoms and signs according to the Framingham Heart Study criteria; and (ii) serum Nâterminal proâBâtype natriuretic peptide level of â„400 pg/mL or brain natriuretic peptide level of â„100 pg/mL. The HFAâPEFF score has functional, morphological, and biomarker domains. We evaluated the prognostic significance of the HFAâPEFF score (calculated based on the data at hospital discharge) on postâdischarge clinical outcomes in this cohort. The primary endpoint of the present study was a composite of allâcause death and heart failure readmission. Between June 2016 and December 2019, 871 patients were enrolled from 26 hospitals (mean followâup duration 399 ± 349 days). A total of 804 patients were finally analysed after excluding patients with scores of 0 (N = 5) and 1 (N = 15) from 824 patients with available HFAâPEFF score based on the echocardiographic and laboratory data at discharge. According to the laboratory and echocardiographic data at the time of discharge, 487 patients (59.1%) were diagnosed as HFpEF (HFAâPEFF score â„ 5) while 317 patients (38.5%) had intermediate score. KaplanâMeier analysis divided by the HFAâPEFF score [low, score 2â5 (N = 494) vs. high, score 6 (N = 310)] indicated that the HFAâPEFF score successfully stratified the patients for the primary endpoint (logârank test P < 0.001). Cox proportional hazard model showed that the HFAâPEFF score was significantly associated with the primary endpoint (high score with reference to low score, adjusted hazard ratio 1.446, 95% confidence interval [1.099â1.902], P = 0.008). Conclusion The HFAâPEFF score at discharge was significantly associated with the postâdischarge clinical outcomes in acute decompensated heart failure patients with preserved ejection fraction. This study suggested clinical usefulness of the HFAâPEFF score not only as a diagnostic tool but also a practical prognostic tool
