CVA, cerebrovascular accident; HCM, hypertrophic cardiomyopathy; INR, international normalised ratio; LV, left ventricular; TIA, transient ischemic attack.
Oral anticoagulation (optimal INR 2–3):
▸ Rheumatic heart disease (mitral stenosis)
▸ Prosthetic heart valve
▸ High risk patients:
    –history of CVA or TIA
    –diabetes mellitus
    –heart failure
    –age >65 years
    –echocardiogram: LV dysfunction, HCM
Aspirin (75–325 mg/daily):
▸ “Lone” atrial fibrillation
▸ No risk factors
