For the most part this test is performed in patients who are suspected of having carotid disease. Patients with symptoms suggestive of either a stroke, or TIA (mini-stroke), or a carotid bruit in either a symptomatic or an asymptomatic patient. We also believe that measurement of cIMT in the common carotid artery is a useful screening test for vascular disease in patients with Intermediate Framingham Risk Scores (FRS, 10-19). Our own data suggests that even patients with a low FRS have a high prevalence of abnormal cIMT in patients referred to a cardiac facility. Patients with abnormal cIMT can be targetted for other vascular preventative therapies such as Aspirin, Statins and even ACE inhibitor therapy. There are no specific pre-test recommendations. The procedure is performed using ultrasound. There are no recognized specific complications. The test is preformed for the following indications.
