Hypertensive crisis is an extreme phenotype of hypertension and hypertension-related thrombotic complications. This is most evident in patients with hypertensive crisis having advanced retinopathy and thrombotic microangiopathy (TMA). We examined whether hypertensive crisis complicated by advanced retinopathy is associated with endothelial dysfunction, platelet activation, thrombin generation and decreased fibrinolytic activity. In addition, we tested the association between these procoagulant changes and the development of TMA and end-organ dysfunction.Several key mediators of coagulation were assessed in 40 patients with hypertensive crisis with and without retinopathy and compared with 20 age, sex and ethnicity-matched normotensive controls. In patients with hypertensive crisis, associations with markers of TMA and renal dysfunction were assessed by regression analysis.Soluble P-selectin levels were higher in patients with hypertensive crisis compared with controls regardless of the presence or absence of retinopathy (P
