Cardiac CT Scan: The Modern Way to Detect Heart Disease Early

Heart disease is one of the leading causes of death worldwide, but the good news is that modern technology people catch it early. One of the most effective tools used today is the Cardiac CR Scan. It is fast, painless, and highly accurate in detecting heart problems before symptoms appear.

At Putra Melaka Hospital, known as one of the best heart catheterization centers, patients can get advanced heart screening with the latest imaging technology, including cardiac CT scans. The hospital’s team of skilled doctors and technicians work together to make sure every patient gets accurate results and quality care.

What Is a Cardiac CT Scan?

A cardiac CT scan (Computed Tomography scan of the heart) is a special imaging test that uses X-rays and computer technology to create detailed pictures of your heart and blood vessels. It allows doctors to see inside your heart without surgery.

The scan provides 3D images of the heart, showing the size, shape, and condition of the coronary arteries — the vessels that supply blood to the heart muscle. It can also detect calcium buildup (plaque) in the arteries, which is one of the early signs of coronary artery disease.

How Does a Cardiac CT Scan Work?

The process is simple and fast. During a cardiac CT scan, you lie on a table that slides into a large, doughnut-shaped machine. The scanner rotates around your chest, taking many X-ray images from different angles. These images are then combined by a computer to produce clear, cross-sectional views of your heart.

Sometimes, a dye called contrast material is injected into your vein before the scan. This helps highlight the blood vessels, making it easier for doctors to see if there are any blockages or narrowing in the arteries.

Why Is Early Detection Important?

Heart disease often develops slowly, with few or no symptoms at first. By the time you feel chest pain or shortness of breath, your arteries may already be significantly narrowed or blocked.

A cardiac CT scan can reveal signs of trouble before symptoms appear. Early detection gives doctors a chance to start treatment early, helping you avoid serious complications such as heart attack or stroke.

Conditions a Cardiac CT Scan Can Detect

A cardiac CT scan can identify a variety of heart and blood vessel problems, such as:

1. Coronary Artery Disease (CAD) – It shows blockages or narrowing caused by plaque buildup.
2. Calcium Score (Coronary Artery Calcification) – It measures how much calcium is in your coronary arteries, helping predict your risk of heart disease.
3. Congenital Heart Defects – It can detect structural problems in the heart that are present from birth.
4. Heart Function Problems – It evaluates how well your heart is pumping blood.
5. Aneurysms or Enlarged Blood Vessels – It can show if your blood vessels are stretched or bulging.
6. Pericardial Disease – It detects thickening or inflammation around the heart.

Who Should Get a Cardiac CT Scan?

You might be a good candidate for a cardiac CT scan if you:

• Have a family history of heart disease
• Have high blood pressure, high cholesterol, or diabetes
• Are over 40 years old and have other risk factors
• Experience chest pain, shortness of breath, or unexplained fatigue
• Are a smoker or have smoked for many years
• Have had an abnormal result from another heart test, like an ECG or stress test

Benefits of a Cardiac CT Scan

There are many reasons why a cardiac CT scan is considered one of the most useful modern tools for heart health. Here are the key benefits:

1.Early Detection

• It can find signs of heart disease before any symptoms appear, giving doctors time to act early.

2. High Accuracy

• The scan produces detailed, high-resolution images of your heart, making it easier to detect even small blockages or calcium deposits.

3. Quick and Non-Invasive

• There’s no surgery or recovery time involved. You can usually return to your normal activities right after the test.

4. Safe and Painless

• It’s completely painless, and the radiation dose is carefully controlled to ensure safety.

5. Guides Treatment

• Results from a cardiac CT scan help doctors plan the right treatment — from medication to lifestyle changes or further tests.

6. Peace of Mind

• Knowing your heart’s condition gives you confidence and helps you take control of your health.

What to Expect During the Procedure

If you’ve been scheduled for a cardiac CT scan, here’s what typically happens:

1. Preparation:

• You may be asked to avoid caffeine or smoking before the scan, as these can affect your heart rate. Wear comfortable clothing and remove metal objects like jewellery.

2. Contrast Injection:

• In some cases, a dye is injected into your arm to help highlight the blood vessels. You may feel a warm sensation for a few seconds.

3. Scanning:

• You’ll lie still on the table while the scanner moves around your chest. The machine may ask you to hold your breath for short periods to get clear images.

4. Completion:

• The scan usually takes less than 15 minutes. Afterward, you can drink plenty of water to help flush the dye from your body.

5. Results:

• A radiologist will analyse the images and send the report to your cardiologist, who will discuss the results and next steps with you.

Are There Any Risks?

A cardiac CT scan is very safe, but like any medical test, it has some small risks. The radiation exposure is minimal and well within safe limits. If a contrast dye is used, there’s a small chance of allergic reaction or temporary kidney issues, especially if you have pre-existing kidney disease.

Always inform your doctor if you’re pregnant, have allergies, or any health concerns before the test. The healthcare team will make sure the procedure is safe for you.

How to Prepare for a Cardiac CT Scan

Preparing for a cardiac CT scan is simple. Here’s what you should do:

• Avoid caffeine and smoking for 4–6 hours before the test.
• Do not eat a heavy meal right before your appointment.
• Wear loose, comfortable clothes.
• Bring a list of your medications and medical history.
• Follow any specific instructions from your doctor or hospital staff.

After the Scan: What Happens Next?

Once your cardiac CT scan is complete, your doctor will review the images to check for any blockages, plaque buildup, or other issues.

If the scan shows no problems, you can continue your regular activities with peace of mind. But if it shows narrowing or calcium buildup in your arteries, your doctor may suggest further tests, medication, or lifestyle changes.
