What Coronary Angiography Involves: Procedure Explained After JP Nadda’s Test

Coronary angiography is a diagnostic imaging technique used to visualise the blood vessels that supply the heart. During the procedure, a thin catheter is inserted through an artery in the wrist or groin and guided to the coronary arteries. A contrast dye is then injected, allowing X‑ray imaging to capture real‑time pictures of the coronary vessels. Physicians assess these images for narrowing, blockages, or other abnormalities that could indicate coronary artery disease. The test helps determine whether medication, angioplasty, or stent placement is required. The recent angiography performed on Minister JP Nadda highlighted the routine use of this test for evaluating cardiac health in emergency admissions.
