title: Secondary prevention of cardioembolic stroke: oldest and newest promises.
abstract: Atrial fibrillation (AF) is the most common cause of cardioembolism. An update on secondary prevention strategies used to protect from the risk of stroke AF patients is presented. The main line of actions of stroke prevention in AF are antithrombotics (anticoagulant or antiplatelet), antiarrhythmics (for rate control and sinus rhythm restore), mechanical means (for occlusion of the left atrial appendage or protection of the internal carotid artery from emboli). Classic pharmacological prevention with K vitamin Kantagonists such as warfarin may be overcome by direct thrombin inhibitors like ximelagatran and melagatran. New ablation technologies promise to cure, at least a part of Nonvalvolae AF in the community, restoring sinus rhythm. Recent achievements on endovascular procedures deploying carotid artery implants provide an opportunity to divert emboli to nonhazardous locations, whereas cardiac devices can seal left atrial appendages and avoid risk of clot migration in the blood stream. In the next decade, the challenge will be to understand competitiveness between old and new drugs with endovascular implants.
