What Is CIMT?
Carotid Intima-Media Thickness (CIMT) is an ultrasound measurement of the inner two layers of the carotid arteries — the vessels that supply blood to your brain. By assessing the thickness of these artery walls, we can identify early changes of atherosclerosis long before symptoms develop.
Benefits of Getting a CIMT (Carotid Intima-Media Thickness) Test:
A CIMT test (Carotid Intima-Media Thickness) is a non-invasive ultrasound that measures the thickness of the inner layers of your carotid arteries — the vessels that supply blood to your brain. This test provides an early, quantitative snapshot of your vascular health long before traditional symptoms or even abnormal lab results appear.
- Detects Early Arterial Plaque
CIMT identifies early plaque buildup — the earliest stage of atherosclerosis (hardening of the arteries) — often years before a heart attack or stroke risk becomes apparent.
This means you can act early with lifestyle, diet, or medical changes to reverse or stabilize plaque formation.
- Predicts Future Heart Disease and Stroke Risk
Clinical studies show CIMT is one of the strongest non-invasive predictors of future cardiovascular events.
A small increase in artery wall thickness can indicate increased risk — even when cholesterol, blood pressure, or other routine labs are normal.
- Reveals “Silent” Vascular Disease
Up to 50% of heart attacks and strokes occur in people with no prior symptoms. CIMT helps uncover hidden arterial disease early, giving you a chance to make changes before a major event occurs.
- Optimizes Training and Recovery for Athletes
For endurance and high-intensity athletes, CIMT helps ensure your arteries are adapting well to your cardiovascular load. It can detect if intense training is promoting healthy vascular elasticity — or if early inflammation or stiffness is occurring.
- Monitors the Impact of Lifestyle and Treatment
CIMT can be repeated annually to track how interventions — such as diet, exercise, statins, or supplements — are affecting arterial health. It’s a measurable, trackable scorecard for your cardiovascular progress.
- Non-Invasive, Painless, Affordable
The test uses simple ultrasound imaging — no needles, radiation, or contrast dyes — and typically takes about 20–30 minutes. It’s one of the most affordable, high-impact preventive screenings available today.
CIMT testing is endorsed by preventive cardiology experts as one of the most reliable, non-invasive ways to measure vascular health and “arterial age.”
