2014 Guideline for the Management of Atrial Fibrillation2014房颤处理指南

AHA/ACC/HRS have released new guidelines for the management of patients with atrial fibrillation (AF). Warfarin is recommended for patients with mechanical heart valves. The target INR should be 2.0 to 3.0 or 2.5 to 3.5 based on the type and location of the prosthesis. For patients with nonvalvular AF with a history of stroke or transient ischemic attack or an otherwise elevated risk of stroke, dabigatran, rivaroxaban, and apixaban are recommended alongside warfarin. Role for aspirin is limited. Radiofrequency ablation is superior to current antiarrhythmic drug therapy for maintenance of sinus rhythm in selected patient populations with nonvalvular AF.美国心脏协会，美国心脏病学院和心律学会发布了新的心房颤动（房颤）处理指南。装有机械性心脏瓣膜的患者建议应用华法令。根据瓣膜的类型和位置其目标INR应为2.0〜3.0或2.5〜3.5。非瓣膜性房颤且有中风或一过性脑缺血发作史或脑卒中风险高的患者，建议使用达比加群，利伐沙班，阿哌沙班以及华法令。阿司匹林作用有限。对某些非瓣膜性房颤患者，射频消融优于目前的抗心律失常药物治疗以维持其窦性心律。
