A cardiac angiogram is about$4,000-$5,000. Cardiac angiography is coronary angiography, which is clinically recommended for patients with obvious angina symptoms or positive exercise plate test and acute myocardial infarction. Coronary angiography is a minimally invasive procedure, which generally involves puncturing a catheter from the radial artery to the opening of the coronary artery and hitting a contrast medium to show the blood vessels of the heart. Coronary angiography results in no stenosis of the blood vessels, the cost is about 4000-5000 dollars just for the examination. If the coronary angiogram reveals a severe frontal stenosis that needs to be treated, the cost varies greatly.
