Abstract

Functional limitations often persist in patients with venous thromboembolism (VTE). The relevance of biomarkers for these outcomes remains unexplored. Therefore, we aimed to investigate the association of hemostatic, inflammatory, and cardiovascular biomarkers with functional limitations 3 months after VTE. We conducted a prospective cohort study, including patients with acute VTE within 21 days of diagnosis. Biomarker levels (D-dimer, fibrinogen, factor VIII [FVIII], von Willebrand factor antigen [VWF], C-reactive protein [CRP], troponin T, N-terminal pro-B-type natriuretic peptide [proBNP]) were measured at inclusion and 3 months. Functional limitations at 3 months were evaluated with the post-VTE functional status (PVFS) scale (0–4, higher indicating more limitations). The association of biomarkers with functional limitations was assessed with proportional odds models adjusted for confounders. Furthermore, we evaluated the area under the receiver operating characteristic curve (AUC-ROC) for the presence of slight-to-severe functional limitations. Overall, we included 290 patients (41.4% of women) with a median age of 54.9 years (interquartile range [IQR]: 43.1–64.2). D-dimer, fibrinogen, FVIII, VWF, and CRP measured at inclusion were independently associated with functional limitations at 3 months. VWF showed the most favorable AUC-ROC (0.62, 95% CI, 0.55–0.69). In patients with pulmonary embolism, troponin T and proBNP were not associated with functional limitations. At the 3-month follow-up, D-dimer was the only biomarker independently associated with functional limitations, yielding an area under the curve (AUC) of 0.62 (95% CI, 0.55–0.69). In conclusion, we identified biomarkers independently associated with functional limitations 3 months after VTE. Our results indicate a role of these biomarkers in the early identification of patients at risk of persistent functional limitations and suggest their involvement in the underlying mechanisms.
