The goal of therapy with vitamin K antagonists (warfarin), and new direct oral anticoagulant drugs (NOAC or DOAC) is the prevention of stroke and embolic events in patients with non-valvular atrial fibrillation and treatment and prevention of venous thromboembolism. In all cases it is necessary to determine renal function with creatinine clearance because it determines the choice and dosage of NOAC’s. It is extremely important to pay attention to older patients with a number of associated conditions and drug interactions, with a high incidence of neurological symptoms and worse outcomes. Oral anticoagulation can represent a challenge, especially in cases of drug overdose or emergencies such as bleeding and need for urgent surgery. The need for the guidelines has emerged during the last years because of new classes of oral anticoagulants being prescribed more frequently. The expert working group of emergency specialists was formed and gathered on Consensus Conference in October 2015 in Zagreb, to design guidelines for the patients with NOAC therapy and provides details of preoperative management and managements in emergency conditions.
