Anticoagulant Drugs

Oral anticoagulant drugs (OALs) are effective agents in the prevention and treatment of thromboembolic complications. However, despite standardization and application progression, OALs represent a significant clinical problem because they are small-therapeutic medicines that easily interact with food and medicine, which can substantially affect the increased or weakened therapeutic effect. Oral anticoagulants are 4-hydroxycoumarin derivatives and vitamin K antagonists, and their pharmacological activity is based on inhibition of the synthesis of coagulation factors in the liver. These drugs are effective in the prevention of venous thromboembolism, acute myocardial infarction (AIM), heart rhythm disorders by type of atrial fibrillation, stroke prevention, and the like. The most important and clinically commonly undesirable effect of OAL is bleeding. The risk of bleeding is greatest during the introduction of the drug in therapy and for the first few months of the onset of therapy. HAS-BLED scor is a skoring system developed to estimate the 1-year risk of major bleeding in patients with atrial fibrillation and is also used for other indications.

Secondary Stroke Prevention

Ischemic strokes related to atrial fibrillation are highly prevalent, presenting with severe neurologic syndromes and associated with high risk of recurrence. Although advances have been made in both primary and secondary stroke prevention for patients with atrial fibrillation, the long-term risks for stroke recurrence and bleeding complications from antithrombotic treatment remain substantial. We summarize the major advances in stroke prevention for patients with atrial fibrillation during the past 30 years and focus on novel diagnostic and treatment approaches currently under investigation in ongoing clinical trials. Non–vitamin K antagonist oral anticoagulants have been proven to be safer and equally effective compared with warfarin in stroke prevention for patients with nonvalvular atrial fibrillation. Non–vitamin K antagonist oral anticoagulants are being investigated for the treatment of patients with atrial fibrillation and rheumatic heart disease, for the treatment of patients with recent embolic stroke of undetermined source and indirect evidence of cardiac embolism, and in the prevention of vascular-mediated cognitive decline in patients with atrial fibrillation. Multiple clinical trials are assessing the optimal timing of non–vitamin K antagonist oral anticoagulant initiation after a recent ischemic stroke and the benefit:harm ratio of non–vitamin K antagonist oral anticoagulant treatment in patients with atrial fibrillation and history of previous intracranial bleeding. Ongoing trials are addressing the usefulness of left atrial appendage occlusion in both primary and secondary stroke prevention for patients with atrial fibrillation, including those with high risk of bleeding. The additive value of prolonged cardiac monitoring for subclinical atrial fibrillation detection through smartphone applications or implantable cardiac devices, together with the optimal medical management of individuals with covert paroxysmal atrial fibrillation, is a topic of intensive research interest. Colchicine treatment and factor XIa inhibition constitute 2 novel pharmacologic approaches that might provide future treatment options in the secondary prevention of cardioembolic stroke attributable to atrial fibrillation.

Abstract Purpose/Background : Oral anticoagulation is recommended for stroke prevention in patients with non-valvular atrial fibrillation (NVAF) and stroke risk factors, but discontinuation rates are high among those treated with vitamin K antagonists (VKA). After the first year of treatment, about half of patients permanently stop taking VKA therapy. We examined persistence to therapy with dabigatran etexilate (DE) in patients enrolled in the global, prospective GLORIA-AF Registry Program. Methods: GLORIA-AF collects data in three phases from routine clinical practice in 44 countries worldwide. Enrollment in Phase II was initiated following approval of DE, the first non-VKA oral anticoagulant (NOAC) available. During this phase, all patients with newly diagnosed NVAF at risk for stroke starting DE are followed for 2 years. This analysis is based on a pre-specified interim analysis once follow-up of the first 3000 DE patients was completed. Patients were recruited between November 2011 and December 2013 at nearly 1,000 sites worldwide, by cardiologists, neurologists and general practitioners. To reduce selection bias, patients were recruited consecutively, irrespective of antithrombotic therapy. Persistence was defined as time from initiation to discontinuation of therapy for >30 days or substitution of initial treatment by another oral anticoagulant. Persistence rates were analyzed on the basis of a time-to-event analysis using the Kaplan Meier method. Results: Among eligible patients, 2,937 were prescribed DE; 823 (27.4%) in North America, 1,503 (50.1%) in Europe, 194 (6.5%) in Latin America, 54 (1.8%) in Africa/Middle East and 363 (12.1%) in Asia. Overall, 55.3% were male, the median age was 71.0 (range 23-98) years; 36.7% were ≥75 years old. The CHA2DS2VASc score was ≥2 in 88.2%, 78.9% had hypertension, 22.7% diabetes mellitus, 10.1% prior stoke and 24.9% heart failure. All but 5 eligible patients took at least one dose of DE. The probability of remaining on DE treatment was 76.6% at 1 year and 69.2% at 2 years (based on Kaplan-Meier method). At the 2 years visit, half of the permanently discontinued patients (418 out of 828) had switched to another oral anticoagulant. Characteristics of patients discontinuing vs. sustaining therapy and relationships to stroke risk and geographical region will be presented. Conclusions: In this global, prospective, cohort of patients newly diagnosed with NVAF and treated with DE, persistence on therapy was high through 2 years of treatment, with an estimated probability of remaining on treatment of about 77% after 1 year and 70% after 2 years. The detailed results will provide a global perspective on the factors that influence treatment persistence in patients prescribed a NOAC for stroke prophylaxis.
