While performing a physical examination on a 65-year-old Asian male, you discover a carotid bruit. He has not experienced any symptoms related to cerebral ischemia. In addition, his neurologic examination is normal and his overall health status is good. An ultrasound examination documents a high-grade stenosis (>60% diameter) in the affected artery.

Which one of the following is the best treatment at this time?

1) Dipyridamole (Persantine), 75 mg three times a day
2) Ticlopidine (Ticlid), 250 mg twice daily
3) An HMG-CoA reductase inhibitor such as pravastatin (Pravachol) or lovastatin (Mevacor)
4) Carotid endarterectomy
5) No treatment as long as he is asymptomatic
