Inflammatory markers and incident heart failure in older men: the role of NT-proBNP.
2021
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 & IL-6 quartiles had 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.
