secondary prevention
• Lifestyle: smoking, exercise, diet, salt, alcohol
• Antiplatelet: not on warfarin and non-hemorrhagic stroke
o Clipidogrel 75mg od OR
o Aspirin 75mg od + dipyridamole S/R 200mg bd
• Oral anticoagulation: rheumatic MV disease, prosthetic valves, dilated cardiomyopathy, AF
o Warfarin vs dabigatran
• Antihypertensives
o Cholesterol: simvastatin 40mg od if total is >3.5mmol/L

Carotid stenosis and carotid endarterectomy
Endarterectomy decreases mortality if carotid stenosis symptomatic
