Anticoagulation therapy — the cardiological and neurological point of view

Determining proper, i.e. effective and safe anticoagulant therapy is often complex interdisciplinary problem. New oral anticoagulants are safer and at least as effective as vitamin K antagonists. The therapy with those agents creates some opportunities; however, it is also associated with some limitations and complications. We present the cases of two patients aged 45 and 86 years whose treatment required extensive interventions by both neurologists and cardiologists and in whom the selection of the appropriate anticoagulant therapy was difficult.
