摘要
Background: Tissue factor (TF), the main trigger of coagulation is important in the propagation of cardiovascular diseases. Based on an in vitro study, we hypothesised that enalapril may blunt the endotoxin-induced, TF-triggered coagulation in humans. Methods: In a randomised, controlled trial, 30 healthy male volunteers received 2 ng/kg of lipopolysaccharide (LPS) after pre-treatment with placebo or enalapril for 5 days or with enalapril 2 h before LPS infusion. Results: Infusion of LPS increased interleukin-6 levels 400 fold, and induced a 10-fold increase in prothrombin fragment, a fourfold increase in d-dimer, and a fivefold increase in plasmin–antiplasmin complexes. However, pre-treatment with enalapril did not blunt LPS-induced coagulation. Conclusions: Our trial provides evidence against a modulatory role of angiotensin converting enzyme in LPS-induced, TF-triggered coagulation.
