Abstract

Background We evaluated markers of inflammation and endothelial dysfunction and their associations with incident cardiovascular disease (CVD), all-cause mortality and progression of coronary artery calcium (CAC) in patients with type 2 diabetes (T2D) and microalbuminuria but without known coronary artery disease (CAD). Methods Prospective study including 200 patients receiving multifactorial treatment. Markers of inflammation (TNF-α, sICAM-1, sICAM-3, hsCRP, SAA, IL-1β, IL-6, IL-8) and endothelial dysfunction (thrombomodulin, sVCAM-1, sICAM-1, sICAM-3, sE-selectin, sP-selectin) were measured at baseline. Adjustment included traditional CVD risk factors, and full adjustment additionally NT-proBNP and CAC. The "SQRT method" assessed CAC progression after 5.8 years, and cut-point was an annualised difference > 2.5. Results Occurrence of CVD (n = 40) and all-cause mortality (n = 26) was traced after 6.1 years. In adjusted and fully adjusted Cox models, TNF-α was a determinant of CVD and all-cause mortality (p ≤ 0.007). Further, in adjusted and fully adjusted logistic regression, TNF-α was related to CAC progression (p ≤ 0.042). Of the other biomarkers, sICAM-3 and thrombomodulin were also associated with both endpoints (p ≤ 0.046), IL-1β with CVD endpoints (p = 0.021), and sVCAM-1 and sICAM-1 with all-cause mortality (p ≤ 0.005). Higher composite z-scores including all markers of inflammation and endothelial dysfunction were associated with CVD and all-cause mortality (p ≤ 0.008). Conclusions In patients with T2D and microalbuminuria without known CAD and receiving multifactorial treatment, biomarkers of inflammation and endothelial dysfunction were independently associated with CVD, all-cause mortality and CAC progression. Especially TNF-α was a robust determinant, even after adjusting for NT-proBNP and CAC.
