Check Angio(A)
A Diagnostic Coronary Angiogram is the gold standard investigation performed by an interventional cardiologist to precisely visualise the coronary arteries, identify blockages, and plan the most appropriate treatment for coronary artery disease.
Overview
A Diagnostic Coronary Angiogram is the most accurate test available to examine your heart's blood vessels — a special contrast dye is injected through a thin catheter into the coronary arteries and real-time X-ray images reveal any narrowing or blockages in precise detail. This vital procedure creates a detailed map of your heart's circulation and helps your cardiologist determine whether you need medication, angioplasty, stenting, or bypass surgery to protect your heart. It is safe, well-tolerated, and provides answers that no non-invasive test alone can deliver.
Types of Coronary Angiography
Coronary angiography can be performed through different access routes and with varying levels of detail depending on the clinical question. Your cardiologist will recommend the most appropriate approach based on your symptoms and prior investigations.
- Standard Diagnostic Angiography (basic coronary artery visualisation)
- Radial Approach Angiography (catheter through the wrist — safer, quicker recovery)
- Femoral Approach Angiography (catheter through the groin)
- Left Heart Catheterisation with Angiography (combined valve and coronary assessment)
- FFR-Guided Angiography (functional severity assessment of borderline lesions)
Risk Factors of Coronary Artery Disease
A Check Angiogram is recommended when symptoms or risk factors suggest significant coronary artery disease. Early identification of these risks gives patients the best chance of preventing a heart attack.
- Long-standing poorly controlled hypertension damaging coronary artery walls
- Elevated cholesterol promoting arterial plaque formation
- Diabetes mellitus significantly increasing risk of coronary artery disease
- Active or previous history of heavy smoking
- Prior heart attack or previous angioplasty requiring follow-up
- Family history of premature coronary artery disease before age 55
Coronary Artery Disease Symptoms
Symptoms prompting a Check Angiogram range from obvious chest pain to subtle signs. Paying attention to these warning signals and seeking medical evaluation promptly can prevent a serious cardiac event.
- Typical chest pain or pressure on exertion (stable angina)
- Unstable chest pain occurring at rest or with increasing frequency
- Abnormal ECG findings suggesting reduced blood flow to the heart
- Positive stress test or nuclear scan indicating possible coronary disease
- Unexplained breathlessness on mild exertion
- Palpitations or episodes of rapid irregular heartbeat
- Pre-operative cardiac assessment before major non-cardiac surgery
- Syncope (fainting) with suspected cardiac cause

- Shave or clean the wrist and groin area as directed prior to admission
- Wear comfortable, loose clothing on the day of the procedure
The Procedure
Step-by-step guide to what you can expect during your check angio(a) procedure.
Specialist Cardiac Evaluation
Your cardiologist thoroughly reviews your symptoms, risk factors, ECG, echocardiogram, and prior investigations to determine whether a diagnostic coronary angiogram is needed to precisely map your coronary arteries and guide your treatment plan.
Safe Preparation for Your Angiogram
Our team confirms your consent, allergy history, kidney function, fasting status, and current medications — adjusting blood thinners or diabetes medications as needed — so your procedure is conducted with the highest standard of safety and preparation.
Comfortable Access and Contrast Injection
Local anaesthesia is applied at the catheter entry site — most commonly your wrist — so you remain comfortable and aware throughout. Contrast dye is then gently injected through the catheter into your coronary arteries while a specialised X-ray camera captures detailed images in real time.
Precise Coronary Artery Imaging
Your cardiologist acquires multiple angiographic views of all your coronary arteries from different angles, creating a detailed and accurate map of any narrowing, blockages, or abnormalities. This information forms the foundation of your personalised treatment strategy.
Expert Analysis of Your Results
Your cardiologist analyses the angiogram images immediately and, where applicable, uses pressure wire measurements (FFR) to determine the functional significance of any narrowing found. This precision ensures your treatment recommendation is based on the clearest possible evidence.
Your Results and Next Steps
Before discharge, your cardiologist discusses the findings directly with you and your family, explaining whether your coronary arteries are normal, whether medication is sufficient, or whether angioplasty or bypass surgery is recommended — giving you complete clarity and confidence.
What to Expect
You will be awake during the angiogram and feel only a brief sting from local anaesthesia at the insertion site — the procedure itself is generally pain-free. Contrast dye injection causes a brief warm flushing sensation that lasts only a few seconds and is completely normal. The procedure takes 20 to 40 minutes and most patients are discharged the same day after 2 to 4 hours of observation.
Recovery
Keep the catheter insertion site clean and dry for 24 hours and apply gentle pressure if any minor bleeding occurs. Rest at home on the day of the procedure and avoid driving, heavy lifting, or strenuous activity for 24 hours. Drink plenty of fluids to help flush out the contrast dye through your kidneys. Contact your cardiologist immediately if you notice significant bleeding, increasing pain at the insertion site, chest pain, or sudden breathlessness.
