Where is this going to go? Two studies are ongoing, one in Europe (SPACE2) and one in the United States (CREST-2), that are going to compare best medical treatment with carotid endarterectomy and carotid stenting. Probably in 3-5 years, we will have an answer to which patients should be treated by which method. Stay tuned. It is an interesting area and it is highly controversial. I admit to my bias and that most asymptomatic patients are best treated medically -- intensive medical treatment and not by endarterectomy or surgery. As time goes by, we will get more information from these 2 good randomized studies, but this will always be a controversial area because of the bias of the physicians doing the procedures and writing the papers. That is my opinion. I am Frank Veith. Thanks for listening.
