Introduction: Hypertension links to a prothrombotic state driven by endothelial dysfunction, reduced fibrinolytic potential and platelet hyperactivity. We hypothesized that ramipril treatment would favourably modify the haemostatic response to a submaximal aerobic exercise session in hypertensives. Methods: Twenty-four hypertensive patients underwent a submaximal exercise test before and after 13±2 months of treatment with ramipril ± hydrochlorothiazide. Hypercoagulability (prothrombin fragments [PF1+2], thrombin- antithrombin complex [TAT] and D-dimers [Dd]), fibrinolytic activity (plasmin-a2-antiplasmin complex [PAP]), endothelial function (von Willebrand factor [vWf] and soluble thrombomodulin [sTM]), and platelet function (soluble P-selectin [sPsel]) were measured before, at peak and one hour after exercise. Results: Antihypertensive treatment resulted in an increase of PAP, vWf and sTM. During the first exercise, PF1+2 were mildly increased at peak exercise (p |
