As the aforementioned coagulation changes induced by air pollution are similar in characteristics and degree to those observed in oral contraceptive users, it may be that coagulation is already activated by oral contraceptives so that no further enhancing effect is observed after exposure to PM 10.Nevertheless, current antiplatelet agents and those still in development, inhibit the thromboxane A 2 or ADP platelet activation pathways but do not interfere with a number of other platelet activation pathways that may contribute to thrombotic events.

Potential mechanisms leading to cardiovascular disease include autonomic dysfunction, systemic and local inflammation, endothelial injury, and alterations in the coagulation cascade 150, 151.Moreover, patients with the metabolic syndrome exhibit endothelial dysfunction (mainly decreased production of nitric oxide and prostacyclin) and heightened platelet reactivity 33.Pulmonary embolism and stroke in relation to pregnancy: how can high-risk women be identified.Alternatively, high fibrinogen levels may simply be a marker of the chronic inflammatory state typical of aging, without directly contributing to the risk 10.The American Heart Association helps you understand the risk factors for excessive blood clotting, also called hypercoagulation.Autoimmune disorders that make it more likely your blood will clot.

Because the vascular endothelium plays an important role in the normal process of haemostasis, any structural or functional change in the vascular wall (involving the extracellular matrix, vascular smooth muscle or endothelium) that occurs during aging may contribute to the increased risk of thrombosis in the elderly, particularly atherothrombosis.
