Atrial fibrillation is most commonly associated with cardiovascular disease
Non cardiac causes: pulmonary disease/PE, hyperthyroidism, sympathomimetics, drugs/ETOH
AFFIRM & RACE trials compared outcomes of a fib patients treated w/ rate vs. rhythm control
- No significant difference in survival between groups
Risk of thromboembolic CVA
- Rhythm control = Rate control + anticoagulation
New data challenges the need for strict heart rate control
- Resting heart rate should be <110 bpm
Use CHADS2 score to identify who requires anticoagulation based on %risk of emboli
- Chronic heart failure, HTN, Age>75, DM, Stroke/TIA
