Eligibility of patients with heart failure with preserved ejection fraction for sacubitril/valsartan according to the PARAGON-HF trial.

aimsIn the heart failure (HF) with preserved ejection fraction (HFpEF) PARAGON-HF trial, sacubitril/valsartan vs. valsartan improved mortality/morbidity in patients with left ventricular ejection fraction (LVEF) below median (57%). We assessed eligibility for sacubitril/valsartan based on four scenarios. METHODS AND

resultsEligibility was assessed in the Karolinska-Rennes study (acute HFpEF, LVEF ≥ 45%, and N-terminal pro-B-type natriuretic peptide ≥300 pg/mL subsequently assessed as outpatients including echocardiography) in (i) a trial scenario (all trial criteria); (ii) a pragmatic scenario (selected trial criteria); (iii) LVEF below lower limit of normal range (<54% in women and <52% in men); and (iv) LVEF below mean of normal range (<64% in women and <62% in men). Among 425 patients [age 78 (72-83) years, 57% women, 28% LVEF ≤ 57% (median in PARAGON-HF), the trial scenario, identified 34% as eligible. Left atrial enlargement and/or left ventricular hypertrophy were present in 99%. Inclusion criteria not met were diuretic treatment and New York Heart Association class. Important exclusion criteria were estimated glomerular filtration rate <30 mL/min/1.73 m

conclusionsIn real-world HFpEF (LVEF ≥ 45%) with N-terminal pro-B-type natriuretic peptide and cardiac structure/function assessed, eligibility for sacubitril/valsartan was according to PARAGON-HF complete criteria 34%, pragmatic criteria 63%, LVEF below lower limit of normal range 5.4%, and LVEF below mean of normal range 41%. Cardiac structural impairment was almost ubiquitous. Ineligibility was more due to exclusion criteria than failing to meet inclusion criteria.
