Activation of coagulation and hyperfibrinolysis in patients with aortic arch atheromatosis (Aortic AA) as a risk factor for cerebral ischemia.

In patients with cerebral ischemia, a frequent finding is atheromatous plaques in the ascending aorta and the aortic arch. Since we were able to demonstrate that patients with atrial fibrillation have an increased coagulatory activity, we wanted to evaluate a potential systemic activation of the coagulatory system in patients with aortic arch atheromatosis (Aortic AA). In 134 consecutive patients, we determined several parameters of the coagulatory and fibrinolytic systems as well as several thrombophilia risk factors and compared the results with 134 age- and sex-matched healthy controls.
