    Abstract:
    β-Blocker (BB) use is a mainstay for the treatment of heart failure (HF) with reduced ejection fraction (HFrEF), whereas its efficacy for heart failure with preserved ejection fraction (HFpEF) remains controversial. Women outnumber men in HFpEF, whereas men outnumber women in HFrEF. Plasma B-type natriuretic peptide (BNP) is established as a biomarker for HF. We examined whether BB use is associated with plasma BNP levels differently in men and women with HFpEF. The study subjects comprised 721 patients with HFpEF [left ventricular ejection fraction (LVEF) ≥ 50%] (184 men, mean age 78.2 ± 9.2 yr and 537 women, mean age 83.1 ± 8.8 yr), 179 on BB (66 men and 113 women) and 542 no BB (118 men and 424 women), 583 in sinus rhythm (SR) and 138 in atrial fibrillation (AF). A multivariable logistic regression test was used. Plasma BNP levels were higher (P = 0.0005), systolic blood pressure and LVEF lower (P = 0.0003, and P = 0.0059, respectively) on BBs than on no BBs in women, whereas in men, plasma BNP levels, systolic blood pressure, and LVEF were not altered significantly (P = 0.0849, P = 0.9129, and P = 0.4718, respectively) on BBs compared with no BBs in patients with SR. Multivariable logistic regression analysis revealed that BB use and women were a positive and a negative predictor for high BNP levels (P = 0.003 and P = 0.032, respectively) in SR but not in AF. BB use was associated with high-plasma BNP levels and lower LVEF in women but not in men with HFpEF and SR, suggesting that the pathogenesis and treatment of HFpEF may differ in men and women in SR.NEW & NOTEWORTHY Pathogenesis and treatment for heart failure with preserved ejection fraction (HFpEF) may differ in men and women in sinus rhythm (SR).
