I25.14: Atherosclerotic heart disease: Left main stem stenosis

Blood vessels in your heart have narrowed.

The heart is supplied with oxygen-rich blood via the coronary arteries. The coronary arteries are blood vessels that run around the outside of the heart. The coronary arteries come out of the aorta. The right coronary artery comes out of the right-hand side. The left coronary artery, which divides into two further left coronary arteries, comes out of the left-hand side. The right coronary artery and the two left coronary arteries each divide into many other small coronary vessels.

Deposits of fat and calcium in the blood vessel walls may cause coronary vessels to narrow. When coronary vessels narrow too much, not enough blood can flow through them. This can cause problems and the heart muscle can become damaged.

Your left coronary artery has narrowed.
