CIMT
Pronunciation: SEE-em-tee
Also written as: CIMT — Carotid Intima-Media Thickness
Carotid intima-media thickness measurement used as a surrogate marker for atherosclerotic disease.
Full Definition
Carotid intima-media thickness (CIMT) is a non-invasive ultrasound measurement of the thickness of the innermost two layers of the carotid artery wall. It serves as a validated surrogate marker for subclinical atherosclerosis and cardiovascular risk stratification. CIMT measurements are typically performed at the common carotid artery and can help identify patients at intermediate cardiovascular risk who may benefit from more aggressive preventive therapy. The measurement is expressed in millimeters, with normal values typically less than 0.9mm and values above 1.0mm considered abnormal.
Usage
Usage note: Always spell out on first use as 'carotid intima-media thickness (CIMT)'.
In Context
- "The patient's CIMT measurement of 1.2mm indicated subclinical atherosclerosis despite normal lipid levels." — Preventive cardiology consultation
- "Annual CIMT monitoring showed progression of intimal thickening over the three-year follow-up period." — Longitudinal study report
