Interpretation
Score 0 (low risk): may not require anticoagulant unless valvular atrial fibrillation
Score 1 (low-moderate risk): should consider anticoagulant / antiplatelet
Score 2 or more (moderate-high risk): anticoagulant is recommended
Notes
- Transthoracic echocardiogram should be done TRO valvular heart disease
