- Coronary Angiography
Coronary angiography is a diagnostic medical procedure used to examine the blood vessels that supply blood to the heart, known as the coronary arteries. It helps doctors identify blockages, narrowing, or other abnormalities that may reduce blood flow to the heart muscle. This test is commonly recommended for patients who experience symptoms such as chest pain, shortness of breath, or suspected heart disease.
The procedure is usually performed in a catheterization laboratory by a cardiologist. During coronary angiography, a thin flexible tube called a catheter is inserted into a blood vessel, typically through the wrist or groin, and guided toward the coronary arteries. A special contrast dye is then injected through the catheter, and X-ray images are taken. The dye makes the coronary arteries visible on the images, allowing doctors to clearly see any blockages or narrowing.
Coronary angiography usually takes about 30 to 60 minutes and is considered a safe and reliable test. It helps doctors decide the best treatment, such as medication, angioplasty, or heart surgery.
