[New orally anticoagulants and brain stroke].

Brain stroke is a grave society problem. About 20% ischemic strokes are cardiac related problems. Atrial fibrillation (AF) is the most common cause of ischemic strokes. Decision to deploy anticoagulant treatment with AF patient depends on bleeding and thrombo-embolic risk which summerise scale CHA(2)DS(2)VASc and HAS-BLED. Past recent years in AF treatment anticoagulants from the group of vitamin K antagonist were used. At present in brain stroke prevention and systemic emboilment, new oral anticoagulants (NOA) which weren't worst than vitamin K antagonists, and they are recomendet in most cases of AF unrelated with heart valve defets. Useing NOA causes lower risk of bleeding, including intracranial heamorrhage. It is believed that this is related to the selective inhibition of specific coagulation factors, and respect other hemostatic mechanisms. Results from clinical studies NOA are encouraging, but still lacks clear answers regarding, among other things: long-term safety of treatment and economically viable in everyday clinical practice. In addition, to date there is no specific antidote for this group of drugs.
