Heart CT Scan - Know Heart Blockage Without Angiography


Coronary artery disease has become the most common CVD in India. This happens mostly due to narrowed or blocked coronary arteries that carry blood to your heart muscle. For such patients with blocked arteries, a few newer techniques other than invasive angiography have taken their place in medical practice. One such technique is a heart CT scan that will create a detailed picture of the heart in a non-invasive way. Here, we have discussed the same.

What is a Heart CT scan?

A computed tomography (CT) scan of the heart is an imaging technique that uses x-rays to produce detailed images of the heart and its blood vessels.

When a coronary calcium scan is performed to determine whether you have a calcium accumulation in your heart arteries or not, it is referred to as a coronary calcium scan.

The test is occasionally combined with scans of the aorta or pulmonary arteries to search for issues with those structures.

Why do you need to go for such a scan?

If your treatment planning is unknown, our doctor may request a heart scan to gain a better picture of your risk of heart disease.

  • A heart scan employs a type of X-ray technology known as multidetector-row or multislice computed tomography (CT).
  • The scan generates a series of pictures that reveal any plaque or calcium deposits inside the blood vessels or arteries.
  • A cardiac scan offers early detection of plaque levels.

Plaque is made up of lipids, cholesterol, calcium, and other blood components. It appears gradually over time, long before any signs or symptoms of an illness appear.

These deposits can obstruct the passage of oxygen-rich blood to the cardiac muscles. Plaque can potentially break and form a blood clot, which can lead to a heart attack.

When do you need a heart scan?

  • If you have a low to moderate risk of heart disease or if your risk of heart disease is unclear, a heart scan may assist as guide therapy.

Based on your risk factors and overall health condition your doctor can advise you whether or not you should get a heart scan.

  • A cardiac scan may also assist in motivating those at intermediate risk to make key lifestyle changes and adhere to treatment recommendations.

How is it performed?

  • You will be instructed to lie down on a table that slides into the CT scanner's centre.
  • You will lie on your back, with your head and feet on each end of the scanner.
  • Small patches(4-5 patches) called electrodes are applied to your chest and attached to a machine that captures the electrical activity of your heart. Your heart rate may be slowed with medication.
  • When you enter the scanner, the x-ray beam spins around you.
  • Slices(a form of images or tomography) are discrete representations of the body produced by a computer.
  • These photographs can be saved, viewed on a computer display, or printed on film.
  • It is possible to make 3D (three-dimensional) models of the heart from the same scan.
  • As the movement generates fuzzy pictures, you must remain motionless during the exam.
  • It is possible that you will be instructed to hold your breath for brief periods( for a few seconds) of time.
  • The full scan includes getting the patient on, reassuring them, connecting them up, doing the test, and getting them off, everything should take no more than 10 minutes.

A Heart CT scan, also known as computed tomography (CT) of the heart, is an imaging technique that uses X-rays to create detailed images of the heart and its blood vessels. It can help detect calcium deposits and plaque buildup in the coronary arteries.
A Heart CT scan may be recommended by your doctor to assess your risk of heart disease, especially if you have risk factors or an unclear treatment plan. It can detect plaque and calcium deposits in the arteries, helping to identify early signs of heart disease.
A Heart CT scan may be necessary if you have a low to moderate risk of heart disease or if your risk is uncertain. Your doctor will assess your overall health and risk factors to determine if a heart scan is appropriate for you.
During a Heart CT scan, you will lie on a table that slides into the CT scanner. Electrodes will be attached to your chest to monitor your heart's electrical activity. The scanner will take X-ray images as it rotates around you, and a computer will create detailed pictures of your heart.
The entire Heart CT scan procedure, including setup and image acquisition, typically takes about 10 minutes to complete.
A Heart CT scan is generally considered safe. However, it does involve exposure to X-ray radiation. The benefits of the scan, such as early detection of heart disease, usually outweigh the potential risks associated with radiation.
Not everyone needs a Heart CT scan. It is typically recommended based on an individual's risk factors and overall health. Some people, such as those with certain medical conditions or allergies, may not be suitable candidates for this type of scan.
A Heart CT scan can detect calcium deposits and plaque buildup in the coronary arteries. These findings can help identify early signs of coronary artery disease (CAD) and assess the risk of future heart events
