Abstract
Aim:To determine the relationship between baseline inflammation (CRP and IL-6) with natriuretic peptide (NP) activity (measured by NT-proBNP) and incident heart failure (HF) in older men.Methods & results:In the British Regional Heart Study, 3569 men without prevalent myocardial infarction or HF were followed for mean 16.3 years; 327 developed HF. Baseline CRP and IL-6 were significantly and positively associated with NT-proBNP. Those in the highest CRP and IL-6 quartiles had an elevated risk of HF after age and BMI adjustment (HR = 1.42 [1.01–1.98] and 1.71 [1.24–2.37], respectively), which markedly attenuated after NT-proBNP adjustment (HR = 1.15 [0.81–1.63] and 1.25 [0.89–1.75], respectively).Conclusion:NP activity is associated with pro-inflammatory biomarkers and may explain the link between inflammation and incident HF.
Highlights
During follow-up, elevated C-reactive protein and interleukin-6 levels were associated with increased incident heart failure (HF)
Risk in models adjusting for age and BMI. This risk disappeared on addition of baseline NT-pro-B-type natriuretic peptide to the model
Natriuretic peptide (NP) activity is linked to pro-inflammatory biomarker activity
Summary
To determine the relationship between baseline inflammation (CRP and IL-6) with natriuretic peptide (NP) activity and incident heart failure (HF) in older men. Using a large cohort of older men, we aimed to determine the relationship between a pro-inflammatory cytokine (IL-6), an acute phase reactant (CRP) and incident HF over a long follow-up period
