Correlation of plasma von Willebrand factor levels, an index of endothelial damage/dysfunction, with two point-based stroke risk stratification scores in atrial fibrillation

In conclusion, in a wide cohort of non-selected and consecutive AF patients, endothelial damage/dysfunction (assessed by plasma vWf levels) but not endothelial activation (sE-sel) correlated with two new risk stratification scores for stroke in AF. Further prospective studies are needed to assess the prognostic role of prothrombotic indices in AF in relation to stroke and thromboembolic events, and their role in complementing clinical risk stratification schemas.
