niacin has been researched along with Carotid Stenosis in 3 studies
Niacin: A water-soluble vitamin of the B complex occurring in various animal and plant tissues. It is required by the body for the formation of coenzymes NAD and NADP. It has PELLAGRA-curative, vasodilating, and antilipemic properties.
vitamin B3 : Any member of a group of vitamers that belong to the chemical structural class called pyridines that exhibit biological activity against vitamin B3 deficiency. Vitamin B3 deficiency causes a condition known as pellagra whose symptoms include depression, dermatitis and diarrhea. The vitamers include nicotinic acid and nicotinamide (and their ionized and salt forms).
nicotinic acid : A pyridinemonocarboxylic acid that is pyridine in which the hydrogen at position 3 is replaced by a carboxy group.
Carotid Stenosis: Narrowing or stricture of any part of the CAROTID ARTERIES, most often due to atherosclerotic plaque formation. Ulcerations may form in atherosclerotic plaques and induce THROMBUS formation. Platelet or cholesterol emboli may arise from stenotic carotid lesions and induce a TRANSIENT ISCHEMIC ATTACK; CEREBROVASCULAR ACCIDENT; or temporary blindness (AMAUROSIS FUGAX).

"The primary endpoint of this study is carotid plaque lipid composition identified by MRI. The determination of plaque lipid content for each carotid artery will be performed using the automated interactive system. These measurements will be performed from the MRI scans at four time points blinded to time sequence of MRI examinations, patient treatment, lipid levels and clinical course.~Volume Measurements: Contours were placed around the lumen, outer-wall boundaries, and plaque features of carotid artery. (Arterial wall area) = (outer-wall area) - (lumen area). Volume calculated as: area x 2 mm (slice thickness). Tissue volume/wall volume x (100%) is presented as percentage. Annualized change presented mm^3/year (for volume) and as percentage change/year." (NCT00715273)
