Coronary Angiogram
Coronary Angiogram in Singapore
Chest discomfort, breathlessness, or unusual test results can leave you wondering if there’s anything wrong with your heart. A coronary angiogram gives doctors a clear view of your coronary arteries, helping to confirm or rule out blockages and guide the best treatment plan for you.
What Is a Coronary Angiogram?
A coronary angiogram is an X-ray test that shows how blood flows through the arteries in your heart, using a contrast dye to highlight blockages or narrowing in the coronary arteries. Unlike standard scans, a coronary angiogram looks directly at the blood vessels of your heart.
How a Coronary Angiogram Works
- During the test, a thin, flexible tube called a catheter is inserted into an artery, usually in your wrist or groin.
- The catheter is carefully guided to the heart.
- Once in place, contrast dye is injected through the catheter.
- As the dye moves through the coronary arteries, X-ray images capture the flow of blood.
These images allow your doctor to see areas where the arteries may have narrowed or become blocked.
Purpose of Coronary Angiogram
A coronary angiogram is not performed on every patient with chest pain or suspected heart disease. It’s usually recommended when other tests, such as an electrocardiogram (ECG) or stress test, suggest reduced blood flow to the heart.
The main purposes of this test are to:
- Confirm or rule out coronary artery disease.
- Identify the location and severity of narrowed or blocked arteries.
- Guide treatment decisions, such as whether medication, angioplasty, or surgery is needed.
When Coronary Angiography Is Recommended
A coronary angiogram is not typically a first-line test for every patient experiencing chest discomfort. It’s usually recommended when other assessments suggest that coronary artery disease could be present or when symptoms are significant.
Your doctor may consider this test if you:
- Experience persistent chest pain (angina) that doesn’t improve with medication or occurs with minimal exertion.
- Have abnormal results from other tests, such as an ECG, echocardiogram, or treadmill stress test.
- Have a known heart disease, in which case more detail is needed to plan further treatment.
- Are following a heart attack, to identify which arteries are affected and whether urgent treatment is needed.
- Are a high-risk patient with multiple cardiovascular risk factors, such as diabetes, high blood pressure, high cholesterol, or a strong family history of early heart disease.

If any of these apply to you, a coronary angiogram may be the next step. Speak with any of our cardiologists to confirm whether you should undergo the test.
Coronary Angiogram Procedure
A coronary angiogram is usually carried out in a hospital’s cardiac catheterisation laboratory. The process involves three stages: preparation, the procedure itself, and recovery afterwards.
Preparing for an Angiography Procedure
- At your consultation, your doctor will review your medical history. You’ll be asked about past reactions to contrast dye, iodine-based products, and if you have asthma or allergies.
- You’ll need to share all the medicines and supplements you’re currently taking at the time of your appointment so your doctor can inform you on which ones to continue and pause.
- You may also need to do blood tests to check how your kidneys are functioning and how your blood clots.
- You’ll usually be asked not to eat or drink for several hours before the procedure. Follow the fasting instructions given to you carefully.
During an Angiography Procedure
- You’ll lie down on a special X-ray table, where monitors will be placed on your chest and arm to track your heart rhythm, blood pressure, and oxygen levels. You’ll stay awake, but you may be given a mild sedative to help you feel more at ease.
- The skin on your wrist or groin will be cleaned, and you’ll get a small injection of local anaesthetic to numb the area. You may feel a quick sting, but after that, just pressure, not pain.
- Once the area is numb, the doctor will insert a thin, flexible tube called a catheter into your artery. Using X-ray guidance, the catheter will be threaded towards your heart. You won’t feel it moving inside you.
- Through the catheter, a special dye will be injected to make your coronary arteries visible on X-ray. You may notice a brief warm sensation as the dye flows through your bloodstream. This is common and passes quickly.
- While the dye is circulating, X-ray images will be taken from different angles. This helps your doctor see if your arteries are narrowed or blocked.
- If a significant blockage is found, your doctor may go ahead with treatment straightaway, such as widening the artery with a balloon (angioplasty) or placing a stent.
- The procedure usually takes about 30 to 60 minutes. If extra treatment is carried out, it may take longer.
Recovery After an Angiography Procedure
- When the catheter is removed, pressure or a compression device will be applied to the access site to stop the bleeding.
- You’ll then rest in a recovery area where nurses will check your heart rhythm, blood pressure, and the puncture site regularly.
- You’ll be encouraged to drink fluids once allowed. This helps flush the contrast dye out of your body.
- Most patients go home the same day, though in some cases your doctor may advise an overnight stay.
- Once home, you can usually return to light activities the next day. Avoid heavy lifting, vigorous exercise, or bending the wrist/hip used for the procedure until your doctor says it’s safe.
- Follow your doctor’s instructions on restarting any medicines you paused before the procedure.
- Keep an eye on the access site. Mild bruising or tenderness is normal, but you should call your doctor straight away if you notice bleeding that won’t stop, swelling, numbness, severe pain, chest discomfort, shortness of breath, or fever.
Understanding Your Coronary Angiogram Results
After the procedure, your doctor will review the X-ray images with you. These images show how well blood flows through your coronary arteries and whether there are any narrowings or blockages.
This is how your results will typically be described:
- Normal Findings: The dye moves smoothly through your arteries with no narrowing.
- Mild Narrowing: A small reduction in blood flow that often doesn’t require immediate treatment.
- Significant Narrowing or Blockage: One or more arteries are severely narrowed or blocked, reducing blood supply to the heart muscle.
Depending on the findings, your doctor may recommend:
- Adjusting or starting medication to improve blood flow and lower cardiovascular risk.
- A procedure to open the artery (angioplasty with or without stenting).
- Surgery, such as coronary artery bypass grafting (CABG), if blockages are extensive.
Risks and Considerations of Coronary Angiogram
Any medical procedure carries some risks. For a coronary angiogram, these can include:
- Bleeding or bruising at the wrist or groin where the catheter was inserted. But this usually settles with pressure or rest.
- Kidney strain due to the contrast dye. This is why, during consultation, you need to inform your doctor or care team of any allergies, so this can be mitigated beforehand.
Cost of Coronary Angiogram in Singapore
The cost of a coronary angiogram depends on where you go, the type of angiogram you undergo, and whether you can apply for an insurance claim or use Medisave.
Factors Affecting Coronary Angiogram Cost
Several factors influence the final bill:
- Type of Angiogram: Conventional catheter angiograms usually cost more than CT coronary angiograms, especially if treatment is performed during the same session.
- Complexity and Urgency: Emergency procedures and complex cases can increase costs.
- Facility and Room Charges: A single room or specialised equipment may add to the cost.
- Specialist and Consultation Fees: Costs vary depending on the cardiologist’s years of practice and seniority.
- Additional Tests or Treatments: Blood tests, medication, or immediate procedures such as angioplasty and stenting increase the total bill.
MediSave and Insurance Coverage
MediSave
You can typically use Medisave to help offset the cost of a coronary angiogram in Singapore. For CT scans, including CT coronary angiograms, the claimable amount is capped at $300 per year. Higher limits may apply if you undergo a catheter-based angiogram or require angioplasty, since these are more complex procedures. Both public hospitals and Medisave-accredited private centres accept Medisave claims.
MediShield Life & Integrated Shield Plans
Beyond Medisave, MediShield Life and Integrated Shield Plans may cover part of the cost if the procedure is deemed medically necessary. The amount covered depends on your plan tier, and you will still be responsible for any co-payments or deductibles.
Private Insurance
If you hold private insurance, the benefits vary depending on your policy. Some insurers allow direct billing with hospitals and specialist centres, while others require you to settle the bill first and then apply for reimbursement.
