Caption: Narrowed heart arteries. Coloured 3D computed tomography (CT) scan of a heart (red) that has stenosis (narrowing) of its coronary arteries. The main part of the heart is at lower right, with the heart blood vessels at upper left. A network of narrow blood vessels (pink) is seen branching out over the surface of the heart. These are coronary arteries, supplying oxygenated blood to keep the heart muscle pumping. These arteries are narrowed in several places (centre right and centre left). These blockages can cause angina (heart pain) or a heart attack. Treatment involves angioplasty to re-open the arteries or implant a stent. In severe cases, coronary artery bypass grafts are used.
