Platelets are key players in atherothrombosis. Antiplatelet therapy comprising aspirin alone or with P2Y12-inhibitors are effective for prevention of atherothrombotic complications. However, there is interindividual variability in the response to antiplatelet drugs, leaving some patients at increased risk of recurrent atherothrombotic events. Several risk(More)
BACKGROUND Atrial fibrillation (AF) is associated with raised levels of P-selectin and an apparent prothrombotic state. However, levels of tissue plasminogen activator (t-PA)-antigen are increased also. We investigated whether high levels of endogenous t-PA-antigen or soluble P-Selectin (sP-Selectin), independently of CHADS(2-) or CHA(2) DS(2) VASc-scores,(More)
BACKGROUND The von Willebrand factor (vWF) is essential for platelet adhesion and arterial thrombosis. It is degraded into less active multimers by ADAMTS13. Patients with atrial fibrillation (AF) exhibit higher plasma vWF and lower ADAMTS13 antigen levels. The vWF/ADAMTS13-ratio might help to estimate the pro-thrombotic risk of patients with AF. We(More)
Von Willebrand factor (vWF) plays an essential role in platelet adhesion and thrombus formation. Patients with atrial fibrillation (AF) exhibit higher plasma vWF and lower ADAMTS13 antigen levels compared to controls. Little is known about vWF and ADAMTS13 in AF patients treated with cardioversion (CV). Thus we investigated the alterations of plasma vWF and(More)
BACKGROUND AND AIM The management of patients with recent-onset atrial fibrillation (AF) presenting at emergency departments (EDs) varies widely. Our aim was to describe the management of patients with recent-onset (<48 hours) AF, to determine safety and efficacy of pharmacological cardioversion at the ED, and to evaluate the incidence of thromboembolism or(More)
BACKGROUND Transcatheter aortic valve implantation (TAVI) has become the standard therapy for high-risk and non-operable patients with severe aortic stenosis. However, the procedure involves several adverse effects, such as rhythm and conduction disturbances. Patients with postprocedural left bundle branch block may have an increased mortality risk, whereas(More)
