Hemostatic and fibrinolytic effects of systemic prostaglandin E1 therapy in patients with peripheral arterial disease.

BACKGROUND: The study was designed to evaluate if there is any evidence of a hyperfibrinolytic bleeding-risk under systemic treatment with prostaglandin E1 (PGE1) of patients with peripheral arterial disease (PAD). PATIENTS AND METHODS: The in vivo effect of PGE1 on the fibrinolytic and hemostatic process was tested on 15 patients before and after treatment with Alprostadil for 21 days using D-dimers (DD), fibrinogen, prothrombin time (PT), partial thromboplastin time (PTT), antithrombin (AT), ProC-Global, plasminogen, plasminogen activator inhibitor activity (PAI), alpha 2-antiplasmin, coagulation factor XII, basal and activated fibrinolytic capacity (fib. cap.). RESULTS: There was no significant difference in DD, fibrinogen, PT, PTT, AT, ProC-Global, plasminogen, PAI, alpha 2-antiplasmin, coagulation factor XII, basal and activated fibrinolytic capacity observed after the treatment. CONCLUSION: Summarizing this study there is no hyperfibrinolytic bleeding-risk after the systemic therapy with Alprostadil to be expected.
