Background The HFA-PEFF algorithm has been recently developed and is recommended by the European Society of Cardiology to make a diagnosis of heart failure with preserved ejection fraction (HFpEF). Based on functional echocardiography criteria, morphological criteria, and natriuretic peptide levels, a score from 1 to 6 is obtained with higher scores indicating a higher probability of HFpEF. Purpose This study investigates the prognostic value of the HFA-PEFF score in HFpEF patients hospitalised for decompensation. Methods This retrospective cohort study includes consecutive patients with HFpEF, admitted to Mayo Clinic Rochester between 2010–2015 and requiring treatment with intravenous loop diuretics for congestion. The HFA-PEFF score was calculated for all patients with echocardiography data available within 1 year and natriuretic peptide levels obtained upon admission. The study population was subsequently stratified according to HFA-PEFF score ≤4 (n=79), =5 (n=93), or =6 (n=271). Incidence rates of recurrent heart failure admissions per 100 patient-years of follow-up, time to all-cause mortality, and mortality causes were compared among strata. Results In 443 patients with HFpEF (78±12 years; 60% women), higher HFA-PEFF score was associated with older age, female gender, higher systolic blood pressure, and worse renal function. Heart failure readmission rates were higher in patients with HFA-PEFF score =5 [46.0 (38.5–53.5)] or HFA-PEFF score =6 [45.0 (40.1–49.8)] versus HFA-PEFF score ≤4 [28.9 (22.7–35.0); P-value&amp;lt;0.001 for differences; see upper panel figure]. Increasing HFA-PEFF score was associated with a shorter median survival (P-value&amp;lt;0.001), which was 65 months (36–89 months) in HFA-PEFF score ≤4, 45 months (26–59 months) in HFA-PEFF score =5, and 28 months (22–42 months) in HFA-PEFF score =6 (see lower panel figure). The proportions of deaths directly related to heart failure were comparable among HFA-PEFF strata (49% versus 49% versus 52%, respectively; P-value=0.903), as was the contribution of cardiovascular death (60% versus 57% versus 63%, respectively; P-value=0.662). Overall, few differences in patterns of mortality causes were observed among strata. There was a lower contribution of primary respiratory disease (mainly chronic obstructive pulmonary disease) to mortality in patients with a higher HFA-PEFF score (26% versus 19% versus 6%, respectively; P-value&amp;lt;0.001). Conclusions Higher HFA-PEFF score in hospitalized patients with HFpEF is associated with increased risk of subsequent heart failure readmissions and all-cause mortality, which includes both heart failure specific and non-heart failure mortality.
