The European Society of Cardiology (ESC) has recently published guidelines for the management of atrial fibrillation.1 Key changes include the identification of more patients at risk of stroke and wider use of oral anticoagulants, a more pragmatic approach to rate control, and a lower threshold for catheter ablation of atrial fibrillation. The priorities in the management of atrial fibrillation (in order of their effect on prognosis) remain as stroke prevention, rate control, and rhythm control⇓.
To incorporate new evidence for the role of oral anticoagulants, the simple and easily remembered CHADS2 scoring system has been modified. The age limit for stroke prevention has been lowered to 65, with an additional point in the scoring system given to those 75 years or more.2 An additional point is also now given for women and those with vascular disease. Table 1⇓ summarises the modified (CHA2DS2-VASc) system.
Other changes are that no treatment is now recommended for a score of zero and oral anticoagulants are recommended over aspirin for a score of 1. Table 2⇓ shows the preferred anticoagulation strategy by CHA2DS2-VASc score. This revised strategy is the result of consistent evidence of the superiority of oral anticoagulants …
