Background The period shortly after hospitalization for heart failure (HF) represents a high-risk window for recurrent clinical events, including rehospitalization or death.
Objectives To determine whether the efficacy and safety of sacubitril/valsartan varies in relation to the proximity to HF hospitalization among patients with HF and preserved ejection fraction (HFpEF).
Methods In this post hoc analysis of PARAGON-HF, we assessed risk of clinical events and response to sacubitril/valsartan in relation to time from last HF hospitalization among patients with HFpEF (≥45%). Primary outcome was composite total HF hospitalizations and cardiovascular death, analyzed using a semiparametric proportional rates method, stratified by geographic region.
Results Of 4,796 validly randomized patients in PARAGON-HF, 622 (13%) were screened during hospitalization or within 30 days of prior hospitalization, 555 (12%) within 31-90 days, 435 (9%) within 91-180 days, 694 (14%) after 180 days, and 2,490 (52%) were never previously hospitalized. Over median 35 months follow-up, risk of total HF hospitalizations and cardiovascular death was inversely and non-linearly associated with timing from prior HF hospitalization (P<0.001). There was a gradient in relative risk reduction in primary events with sacubitril/valsartan from patients hospitalized within 30 days (rate ratio 0.73; 95% confidence interval 0.53-0.99) to patients never hospitalized (rate ratio 1.00; 95% confidence interval 0.80-1.24); trend in relative risk reduction Pinteraction=0.15. With valsartan alone, rate of total primary events was 26.7 (≤30 days), 24.2 (31-90 days), 20.7 (91-180 days), 15.7 (>180 days), and 7.9 (not previously hospitalized) per 100 patient-years. Compared with valsartan, absolute risk reductions with sacubitril/valsartan were more prominent in patients enrolled early after hospitalization: 6.4% (≤30 days), 4.6% (31-90 days), 3.4% (91-180 days), while no risk reduction was observed in patients screened >180 days or who were never hospitalized; trend in absolute risk reduction Pinteraction=0.050.
Conclusions Recent hospitalization for HFpEF identifies patients at high-risk for near-term clinical progression. In the PARAGON-HF trial, relative and absolute benefits of sacubitril/valsartan compared with valsartan in HFpEF appear to be amplified when initiated in the high-risk window after hospitalization and warrants prospective validation.
