Statin drugs may delay progressive artery damage in children
... To assess the drugs effectiveness, the team used ultrasound
to measure intima media thickness (IMT) in the carotid artery in the neck. IMT is the combined thickness of the intima and media, two layers of the artery wall. Carotid IMT is widely accepted as a standardized and validated surrogate marker for athe...
