Abstract
Background: To investigate the effect of beta-blockers according to NP levels and HF phenotypes because natriuretic peptide (NP) level can be used to risk-stratify HF patients regardless of left ventricular ejection fraction (LVEF).

Methods: Of 5,625 patients in the Korean acute heart failure registry, we included patients with LVEF and NP levels. HF phenotypes were defined as HF with reduced ejection fraction (HFrEF) (EF ≤ 40%), HF with midrange ejection fraction (HFmrEF) (40% < EF < 50%), and HF with preserved EF (HFpEF) (EF ≥ 50%). Patients were further stratified by NP tertiles. Primary outcome was 5-year all-cause mortality according to beta-blocker use at discharge.

Results: Both B-type NP (BNP) (r = -0.279, P < 0.001) and N-terminal pro-BNP (r = -0.186, P < 0.001) levels correlated inversely with LVEF. During a median follow-up duration of 961 days, 1560 (35.3%) patients died. In HFrEF, patients taking beta-blockers showed better survival regardless of NP levels. Regarding HFmrEF, there was no mortality difference between those taking and not taking beta-blockers. In HFpEF, beta-blocker use demonstrated lower mortality in those in the 3rd NP tertile (log-rank P = 0.041) but not in those in the 1st and 2nd NP tertiles (log-rank P > 0.05). After adjusting covariates, the use of beta-blockers was associated with a 38%-reduced mortality (hazard ratio: 0.62; 95% confidence interval: 0.39-0.98; P = 0.040) in HFpEF patients in the 3rd NP tertile but not in those in 1st and 2nd tertiles.

Conclusions: We confirm that the use of beta-blockers is beneficial in patients with HFrEF. Furthermore, we extend the benefits of beta-blockers to patients with HFpEF and high NP levels.
