CRP and atrial fibrillation: The correlation between declined FEV1 and FEV1/FVC and the incidence of AF was significantly attenuated after adjusting the inflammation biomarkers in a cohort study (7); FEV1 and FVC were inversely correlated with C-reactive protein (CRP) and fibrinogen in early adulthood (50, 51); the associations were identified between FEV1 and FVC and circulating levels of adhesion molecules such as intercellular adhesion molecule (ICAM) and P-selection (52); indicating that some risks may be mediated by inflammation.
