Carotid Intima-Media Thickness (CIMT) Test (2024)

Carotid Intima-Media Thickness (CIMT) Test

CIMT test for carotid arteries.

What Is Carotid Intima-Media Thickness Test?

The CIMT test uses ultrasound technology to measure the thickness of the inner two layers (intima and media) of the carotid arteries. It detects early signs of atherosclerosis, a condition where arteries narrow due to plaque buildup from fats, cholesterol, and other substances, restricting blood flow. CIMT is a non-invasive predictor of cardiovascular diseases like heart attacks and strokes, allowing for timely intervention. In 2022, cardiovascular disease was a significant health concern in Singapore, with approximately 23 deaths occurring daily and accounting for 31.4% of all deaths locally.

Given that cardiovascular disease is a leading cause of death in Singapore, early detection allows preventive measures such as lifestyle modifications, medications, and other interventions that can reduce the risk of serious health complications and potentially save lives.

Procedure for CIMT Test

CIMT test is generally performed as follows:

  • Preparation: The patient should remove all neck jewellery and obstructions and stand in a relaxed position.
  • Application: A gel is applied to the neck area. This gel ensures good contact between the transducer and the skin, eliminating air pockets that could distort the ultrasound waves and affect image quality, ensuring clear and precise imaging.
  • Ultrasound: The transducer is moved along the carotid artery. The technician carefully manoeuvres the probe to capture high-resolution images of the artery walls.
  • Measurement: The thickness of the intima and media layers is measured from the ultrasound images. The measurements are typically taken at multiple points along the carotid artery to ensure accuracy.
  • Analysis: The collected images and measurements are analysed by the doctor to assess the presence and extent of atherosclerosis.

Interpreting CIMT Results

An increased intima-media thickness indicates a higher risk of atherosclerosis. The doctor will review these results, consider the patient’s overall health, lifestyle, and risk factors, and determine the best course of action for preventing cardiovascular disease. Possible interventions can include lifestyle modifications such as dietary changes and increased physical activity, medications to manage cholesterol and blood pressure, and regular monitoring to track the progression of atherosclerosis.

CIMT vs. Other Cardiovascular Tests

CTCA and CT Calcium Scoring through computed tomography.
Stress tests to evaluate heart function.

CIMT is a non-invasive, safe, and quick procedure that specifically measures the thickness of the carotid artery walls, focusing on early detection of atherosclerosis. This differs from other cardiovascular tests, each with its unique purpose:

  • Electrocardiogram (ECG): Measures the electrical activity of the heart to detect arrhythmias, heart attacks, and other cardiac conditions.
  • CT Coronary Angiography (CTCA): Uses computed tomography (CT) scans to provide detailed images of the heart’s blood vessels, assessing for any blockages.
  • CT Calcium Scoring: Uses computed tomography (CT) scans to detect the buildup of calcified plaque in the coronary arteries.
  • Stress Tests: Evaluate heart function under physical stress, useful for detecting significant blockages and assessing overall cardiovascular fitness.

Each of these tests complements CIMT by providing comprehensive insights into different aspects of cardiovascular health and risk for cardiovascular-related diseases.

Summary

The CIMT test is a valuable, non-invasive tool for early detection of atherosclerosis, essential in managing cardiovascular health. In Singapore, where cardiovascular disease is a leading cause of death, regular CIMT screenings can identify early artery narrowing, allowing for timely interventions. By complementing other cardiovascular tests, CIMT offers comprehensive insights into heart health, aiding in the prevention of serious cardiovascular complications and improving patient outcomes. If you are unsure if CIMT is suitable for you, schedule an appointment with our doctors to discuss more about your cardiovascular health.

Frequently Asked Questions (FAQs)

A carotid ultrasound visualises the structure and blood flow of the carotid arteries to assess the presence of plaque inside the carotid arteries. CIMT specifically measures the thickness of the inner two layers (intima and media) of the carotid artery to detect early atherosclerosis.
Your CIMT score will be compared with population averages based on data sets. Scores that are higher than 75% of the population signify an increased cardiovascular risk.
A CIMT test, or Carotid Intima-Media Thickness test, measures the thickness of the carotid artery's inner layers to assess atherosclerosis risk.
Yes, the CIMT test is worth it for early detection of atherosclerosis, allowing for preventive measures to reduce cardiovascular risk.
CIMT is used to detect early atherosclerosis and assess the risk of cardiovascular diseases such as heart attacks and strokes.
Symptoms of a blocked carotid artery include sudden weakness, confusion, trouble speaking, vision problems, and dizziness, often indicating a transient ischemic attack (TIA) or stroke.
CIMT results showing increased thickness indicate higher risk of atherosclerosis and cardiovascular events. Your doctor will provide a detailed analysis based on overall health and risk factors.
Your CIMT score will be compared with population averages based on data sets. Scores that are higher than 75% of the population signify an increased cardiovascular risk.
Minimal to no blockage is considered normal. Any significant blockage requires medical attention.
Your CIMT score will be compared with population averages based on data sets. Scores that are higher than 75% of the population signify an increased cardiovascular risk.
A CIMT test in Singapore typically costs between SGD 200 and SGD 500.
The purpose of a CIMT test is to detect early signs of atherosclerosis, allowing for preventive interventions to reduce cardiovascular disease risk.
Thickening of the carotid artery indicates the early stages of atherosclerosis, increasing the risk of cardiovascular diseases like heart attacks and strokes.
