CIMT test (Carotid Intima-Media Thickness Test) that shows the risk of heart attack and stroke early

Do you have high cholesterol, high blood pressure, or diabetes? Or has anyone in your family ever had a heart attack or stroke? Things like these can cause a little fear in our minds, right? These diseases don't happen overnight. They have been growing inside our bodies for years, slowly and silently. So how great would it be if there was a way to identify the first signs of these dangerous diseases before they even appear? Today, we're going to talk about a test that many people haven't heard of, but is very important.

Simply put, what is this CIMT test?

The full meaning of CIMT is Carotid Intima-Media Thickness . Okay, the name may sound a bit complicated, but the way it works is very simple. Let's break it down a bit and understand.

There are two main blood vessels on either side of your neck that carry blood to your brain. These are what we call the Carotid Arteries . These arteries are not just tubes, they also have a wall. This wall is made up of three main layers. The CIMT test measures the thickness of the two innermost layers of that wall - the intima, which is the thinnest layer that comes into contact with blood, and the media, which is the muscular layer underneath it.

Think of a water pipe. Over time, rust and dirt build up inside the pipe, thickening the wall of the pipe and reducing the space for water to flow through, right? That's how it is with our blood vessels. When fats like cholesterol start to build up inside the blood vessels, the blood vessel walls gradually start to thicken. This is what we call atherosclerosis in medicine.

This is like a red light that we get before a major illness develops. It means that we have an opportunity to take the necessary steps and avoid that major danger in advance.

Who wants to take this test?

Usually, your doctor will only recommend this test if you have risk factors for atherosclerosis. Not everyone needs to have this test. These are the main risk factors.

If you have one or more of these risks, you can talk to your doctor to find out if this CIMT test is right for you.

How is this test done? Is it something to be afraid of?

There is nothing to be afraid of! The CIMT test is painless, non-invasive, and similar to an ultrasound scan performed on a pregnant woman. It does not use any radiation.

This test is usually performed by a technician who has received special training in ultrasound scanning. Here is how it happens step by step.

Do you need to prepare before the test?

No special preparation is required. You can eat and drink as usual. However, it is easier to wear a dress with wide shoulders and buttons that exposes your neck area.

What happens during the test?

This entire test takes about 30 to 45 minutes.

1. Preparation: You will be made to lie down on an examination table and be in a comfortable position.

2. Applying a gel: Then, a small amount of cold gel is applied to the sides of your neck. This gel helps to create a good connection between the scanning device (probe) and the skin and allows the sound waves to be easily transmitted into the body.

3. Scanning: Now the technician will place a small device called a transducer on your neck and slowly move it around. You will feel a little pressure during this time, but it will not hurt. Sometimes you will be asked to turn your head slightly.

4. Taking pictures: High-frequency sound waves (ultrasound waves) emitted by the transducer travel down the neck, hit the arteries inside, and bounce back. The returning waves are picked up by the transducer and sent to a computer. The computer analyzes the data and produces a clear picture of the artery wall and a measurement of its thickness in millimeters.

5. Finishing: After all the necessary pictures and measurements have been taken, the gel applied to your neck will be wiped off and you will be sent home. You can continue with the rest of your work for the day without any interruptions.

What does the investigation report say?

The results of the CIMT test are a measure of the thickness of the inner two layers of your carotid artery wall. These images and measurements are reviewed by a radiologist who prepares a report.

Once the doctor treating you (your family doctor or cardiologist) receives the report, he or she will explain it to you.

If the results are abnormal, what do you do next?

Imagine that your CIMT report says that your artery walls are thickened. Don't panic. The best part is that you'll know about it before it happens . Now you and your doctor can work together to make a plan to reduce your risk.

Your doctor will often recommend things like:

• Starting medication: You may be asked to start medications to lower cholesterol (e.g., statin drugs), control blood pressure, or prevent blood clots (e.g., aspirin).
• Lifestyle change:
• Diet: Reduce foods high in oil, sugar, and salt, and eat more heart-healthy foods like vegetables, fruits, legumes, and fish.
• Exercise: Start exercising, such as walking or cycling, for at least 30 minutes a day.
• Quitting bad habits: If you smoke, quit completely.

By following these steps, you can control further thickening of the artery walls and perhaps even reverse the condition to some extent.
