Coronary Angiography with Angina Phenotyping (via Imaging-Based Analysis)
This test involves imaging your heart arteries during chest pain episodes to assess blood flow and identify areas of concern, such as blockages or reduced blood supply.
["Helps doctors understand how your chest pain relates to your heart’s blood flow and guides treatment decisions."]

What This Test Measures
The test uses specialized imaging (such as coronary angiography) to visualize your coronary arteries while you experience angina (chest pain). This helps evaluate how blood flows through your heart during pain episodes, identifying potential blockages or narrowing that may trigger symptoms.
Why It’s Done
Your doctor may recommend this test if you have frequent or severe chest pain that doesn’t clearly match typical heart attack or anxiety symptoms. It helps determine whether your pain is due to reduced blood flow to your heart muscle, which can guide decisions about further testing or treatment.
Preparation and Process
You’ll likely need to fast for a few hours before the procedure. A catheter is inserted into a blood vessel (usually in your arm or groin), and contrast dye is injected to make your arteries visible on X-ray. You may feel pressure or a brief burning sensation, but you’ll be sedated to stay comfortable.
Risks and Considerations
While generally safe, this procedure carries minor risks like allergic reactions to dye, bleeding at the insertion site, or temporary nerve damage. Most people recover quickly, but serious complications are rare.
Reference range
Not applicable - this is a diagnostic confirmation outcome rather than a quantitative analyte. Result reported as positive/negative for angina pectoris confirmed by angiographic evidence of coronary artery stenosis.N/A
Patient should be informed about the invasive nature of coronary angiography including risks of bleeding, infection, allergic reaction to contrast media, and vascular complications. Fasting may be required per institutional protocol prior to catheterization. Review medication history including anticoagulants, metformin, and renal function.
