Epidemiologic research has shown that current low-dose estrogen oral contraceptives are associated with a low risk of vascular events (e.g., myocardial infarction, stroke, and venous thrombosis or thromboembolism). Yet questions still persist about the effects of low-dose oral contraceptives on the cardiovascular system. Changes in the coagulation system have been linked primarily to the estrogen component; however, it has been proposed that the progestin may have an influence on the fibrinolytic system. Desogestrel, a new gonane progestin, has been commercially available in Europe since 1981. It has been widely shown to produce minimal changes of the coagulation and fibrinolytic systems, and it has not been associated with an increased risk of thromboembolic disorders.
