The study found that interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-alpha), and C-reactive protein (CRP) are associated with the incidence of heart failure (HF), with IL-6 and CRP specifically linked to HF with preserved ejection fraction (HFpEF), but not with HF with reduced ejection fraction (HFrEF) or HF with midrange EF (HFmrEF).
Chronic systemic inflammation is associated with an increased risk of heart failure (HF). We sought to determine the association between biomarkers of systemic inflammation interleukin (IL)-6, IL-2, tumor necrosis factor alpha (TNF-alpha), and C-reactive protein (CRP) with those of HF and its subtypes. We hypothesize that inflammatory biomarkers IL-6, IL-2, TNF-alpha, and CRP are associated with HF and its subtypes. We included participants from the Multi-Ethnic Study of Atherosclerosis (a prospective population-based cohort study [2000 to 2002]), without a history of HF, and with available baseline inflammatory biomarkers. We explored the association of IL-6, IL-2, TNF-alpha, and CRP with incident HF, HF with reduced ejection fraction (left ventricular ejection fraction [LVEF] < 40%, HFrEF), HF with midrange EF (LVEF 40% to 50%, HFmrEF), and HF with preserved ejection fraction (LVEF > 50%, HFpEF). Among 6,814 participants, 195 developed HF over 10.9 years (56 HFrEF, 30 HFmrEF, and 57 HFpEF). In the models adjusted for clinical risk factors of HF, IL-6 (hazard ratio [HR] 1.33 per doubling; 95% confidence interval [CI] 1.10 to 1.60), TNF-alpha (HR 2.49 per doubling; 95% CI 1.18 to 5.28), and CRP (HR 1.18 per doubling; 95% CI 1.06 to 1.30) were associated with all HF, and IL-6 (HR 1.51 per doubling; 95% CI 1.09 to 2.10) and CRP (HR 1.21 per doubling; 95% CI: 1.01 to 1.45) were associated with incident HFpEF, whereas none of the examined biomarkers were associated with HFmrEF or HFrEF. In conclusion, inflammatory biomarkers (IL-6, TNF-alpha, and CRP) are independently associated with incident HF. IL-6 and CRP are associated with incident HFpEF but not HFrEF or HFmrEF. These findings suggest that activation of the IL-6/CRP pathway (as cause, consequence, or epiphenomenon) may be unique to HFpEF. (C) 2021 Elsevier Inc. All rights reserved.
