Aim: Impaired fibrinolysis is frequently observed in patients with the metabolic syndrome. Aim of the study was to examine the short-term effect of angiotensin II receptor blockade on the fibrinolytic system. Methods: Seventy-four patients with mild hypertension were randomly assigned to a 7-day treatment period with either 16 mg candesartan cilexetil or placebo. Several variables of the fibrinolytic system such as plasminogen activator inhibitor-1 (PAI-1) antigen and activity, tissue plasminogen activator (t-PA) antigen and activity as well as circulating t-PA/PAI-1 complexes were determined. Results: At baseline, the body mass index but not blood pressure was positively associated with PAI-1 antigen (r = 0.314, p < 0.01) and PAI-1 activity (r = 0.425, p < 0.01) but negatively with t-PA activity (r = -0.187, p < 0.05). A 7-day treatment with 16 mg candesartan cilexetil resulted in a significant greater reduction of diastolic blood pressure (-10.3 ± 10.8 mmHg vs.-5.8 ± 8.5 mmHg, p = 0.03). However, there was no significant effect of candesartan on all parameters of the fibrinolytic system under investigation, i.e. circulating PAI-1 antigen, PAI-1 activity, t-PA antigen, t-PA activity and t-PA/PAI-1 complexes. Furthermore, candesartan did not affect the characteristic circadian pattern of the variables of the fibrinolytic system. Conclusion: We conclude that short-term blockade of the angiotensin II receptor subtype 1 with candesartan does not have an impact on fibrinolysis in patients with mild hypertension.
