Hoyt et al identified risk factors for complications following atrial fibrillation. These can help to identify a patient who may benefit from alternative therapy or referral to an expert. The authors are from the Johns Hopkins University.


Risk factors for complications:

(1) female gender

(2) CHADS2 score >= 2 (for age >= 75 years, CHF, diabetes, history stroke, hypertension)

(3) low institutional or operator experience


Additional factors to consider:

(1) comorbidity not measured by CHADS2

(2) use of the latest techniques
