Drugs blocking the renin-angiotensin system, angiotensin converting enzyme
inhibitors and AT(1) receptor antagonists, among many pharmacological effec
ts may exert an antithrombotic action. The mechanisms, which mediate their
antithrombotic activity are associated with enhanced nitric oxide and prost
acyclin release or with attenuation of angiotensin IT action (;Fig. I, 2).
Nevertheless, endothelium plays an important role in this process linking t
he renin-angiotensin and fibrinolysis/coagulation systems.
