Coronary Angiography (CAG) is a specialized diagnostic procedure used to visualize the coronary arteries — the blood vessels that supply the heart muscle. It helps detect blockages, narrowing, or abnormalities in the arteries that may cause chest pain, heart attacks, or other cardiac conditions. What is CAG? CAG is performed using a contrast dye and X-ray imaging (fluoroscopy). A thin, flexible catheter is inserted through the wrist or groin artery and guided to the coronary arteries. Once the contrast dye is injected, X-ray images are taken to show the flow of blood through the coronary vessels. When is Coronary Angiography recommended? Chest pain (angina) or tightness Positive stress test or abnormal ECG Suspected or confirmed heart attack (MI) Coronary artery disease risk in diabetic or high-risk patients Prior to angioplasty (PCI) or cardiac surgery What does it reveal? Location and severity of arterial narrowing or blockage Condition of the heart chambers and valves Need for further intervention such as angioplasty or bypass surgery Procedure Highlights Minimally invasive, typically done under local anesthesia Takes about 20–30 minutes Most patients are discharged the same or next day Performed in a dedicated Cath Lab by expert interventional cardiologist Dr.Chetan Jain
