Worsening Heart Failure Episodes Outside a Hospital Setting in Heart Failure With Preserved Ejection Fraction

Abstract

Objectives: This study sought to evaluate the frequency and prognostic implications of urgent heart failure (HF) visits in a large global clinical trial of HF with preserved ejection fraction (HFpEF). Background: Episodes of worsening HF managed without hospitalization are common and prognostically important in HF with reduced ejection fraction (EF). The significance of these ambulatory worsening HF events in HFpEF is uncertain. Methods: PARAGON-HF (Prospective Comparison of ARNI with ARB Global Outcomes in HF with Preserved Ejection Fraction) randomly assigned 4,796 patients with HFpEF (≥45%) to treatment with sacubitril/valsartan vs. valsartan with a primary composite endpoint of total HF hospitalizations and cardiovascular death. Urgent ambulatory HF visits requiring intravenous diuretic treatment were prospectively collected and adjudicated by a blinded committee. We examined the effect of study treatment on a prespecified expanded composite of cardiovascular death and worsening HF events (including HF hospitalizations and urgent HF visits) and the effect of each type of HF event on subsequent mortality. Results: Of 884 first worsening HF events, 66 (7.5%) were urgent HF visits. Patients whose first episode of worsening HF event was an urgent visit had similar age, comorbidities, baseline N-terminal prohormone of B-type natriuretic peptide, and Meta-Analysis Global Group in Chronic Heart Failure risk scores to those in whom the first HF event was a hospitalization (all comparisons p > 0.05). Regardless of the treatment setting, patients with a first episode of worsening HF had higher rates of subsequent death (19.2 per 100 patient-years; 95% confidence interval [CI]: 16.9 to 21.8 for HF hospitalization and 10.1 per 100 patients-years; 95% CI: 5.4 to 18.7 for urgent HF visit) compared with those who did not experience worsening HF (death rate 4.0 per 100 patient-years; 95% CI: 3.6 to 4.4). Including total urgent HF visits in the composite study endpoint added 95 total events and would have shortened the trial duration needed for event accrual. The addition of urgent HF visits in a prespecified composite endpoint reinforced the treatment efficacy of sacubitril/valsartan compared with valsartan (rate ratio 0.86; 95% CI: 0.75 to 0.99; p = 0.040). Conclusions: Like HF hospitalizations, worsening HF events treated in the ambulatory setting are prognostically important in HFpEF. Inclusion of these events in the composite primary endpoint underscores the benefit of sacubitril/valsartan compared with valsartan in PARAGON-HF.
