Cardiac CT: Purpose, Procedure and Cost in Delhi

Cardiac CT, also known as a cardiac computed tomography scan or coronary CT angiography (CTA), is a non-invasive imaging test that provides detailed pictures of the heart and its blood vessels. Using advanced X-ray technology and computer processing, a cardiac CT creates cross-sectional images that help in detecting coronary artery disease, structural heart problems, and other cardiovascular abnormalities. This diagnostic tool is becoming increasingly popular in Delhi due to the city's rising incidence of heart-related conditions, particularly among middle-aged and elderly populations. With growing awareness, enhanced healthcare infrastructure, and access to advanced imaging technologies, Delhi offers numerous reputed hospitals and diagnostic centers equipped for cardiac CT procedures.

This blog outlines the purpose, procedure, and cost of a cardiac CT scan in Delhi, followed by a concise conclusion and a list of frequently asked questions.

Purpose of a Cardiac CT

Cardiac CT is primarily used to evaluate the heart’s anatomy and detect cardiovascular issues. It is often recommended for individuals who have risk factors for heart disease, such as high blood pressure, diabetes, high cholesterol, smoking history, or a family history of cardiac conditions.

Common reasons for undergoing a cardiac CT include:

1. Detection of Coronary Artery Disease (CAD)
   A cardiac CT scan helps in identifying plaque buildup or blockages in the coronary arteries before symptoms appear or before they worsen.
2. Evaluation of Chest Pain
   It is used to investigate unexplained chest discomfort or pressure, which may be linked to narrowed or blocked arteries.
3. Pre-Surgical or Pre-Procedure Assessment
   Patients undergoing heart surgery or interventions like angioplasty may need a cardiac CT to assess anatomy and guide treatment planning.
4. Monitoring Known Heart Conditions
   Individuals with known heart disease can be monitored for progression or complications through regular cardiac CTs.
5. Congenital Heart Defects
   It helps detect structural abnormalities in the heart that are present from birth.
6. Evaluation of Cardiac Masses or Tumors
   Rare tumors or abnormal growths in the heart can be detected and assessed using a CT scan.
7. Post-Bypass Surgery Assessment
   It evaluates the patency of grafts in patients who have undergone coronary artery bypass surgery.
8. Calcium Scoring
   A specialized form of cardiac CT (called a coronary calcium scan) is used to assess the level of calcium in the coronary arteries—an early indicator of heart disease risk.

Procedure: What Happens During a Cardiac CT Scan

A cardiac CT scan is generally quick, non-invasive, and safe. The entire process—from preparation to post-procedure instructions—usually takes less than an hour.

1. Preparation

• Patients are usually asked to fast for 4–6 hours before the test.
• Beta-blockers may be administered to slow the heart rate, improving the clarity of images.
• You should inform the technician about any known allergies (especially to iodine contrast), kidney issues, or pregnancy.

2. Use of Contrast Dye

• Most cardiac CTs are performed with contrast dye to visualize blood vessels clearly.
• The dye is injected through a vein in your arm and enhances the visibility of arteries, heart chambers, and any blockages.
• Some patients may experience a warm sensation or metallic taste temporarily after the injection.

3. Scanning Process

• You will lie on a motorized table that slides into a doughnut-shaped CT scanner.
• Your chest may be connected to ECG leads to synchronize image capture with the heart's rhythm.
• The technician will guide you to hold your breath for a few seconds while the scanner captures the images.
• The scan itself usually takes around 10–15 minutes.

4. Post-Scan Instructions

• If contrast dye is used, drinking plenty of water afterward helps flush it out of your system.
• Most patients can resume regular activities immediately after the procedure.

Cost of Cardiac CT in Delhi

The cost of a cardiac CT scan in Delhi depends on several factors such as the type of scan, use of contrast, the healthcare provider, and the sophistication of the imaging equipment used. The average cost of Cardiac CT in Delhi ranges from Rs. 3500 to Rs. 7000. Discounts may also be available through health check-up packages or online bookings.

Conclusion

Cardiac CT has revolutionized non-invasive cardiac imaging by providing high-resolution, real-time pictures of the heart and blood vessels. It plays a vital role in diagnosing, evaluating, and managing various cardiovascular conditions—often before they manifest symptoms.  For residents of Delhi, access to world-class diagnostic facilities makes it easier to opt for early screening and timely intervention, especially for those with a family history of heart disease or other risk factors. While the cost may vary based on the scan type and facility, the value it provides in terms of early detection and prevention of serious cardiac events is substantial.

If you or a loved one experiences symptoms like chest pain, breathlessness, or unexplained fatigue, a cardiac CT may be the next crucial step in your healthcare journey. Always consult a cardiologist to determine whether this test is appropriate for your case.
