Coronary heart disease

In coronary heart disease (CHD), layers of fatty material build up inside the coronary arteries. The space available for blood to pass through becomes narrower, so less blood flows to the heart muscle. Its cells then receive less oxygen.

One example is coronary heart disease (CHD): fatty deposits narrow the coronary arteries that supply the heart muscle. Less blood can then reach the muscle, reducing its supply of oxygen. Treatment may aim to lower the chance of further narrowing, improve blood flow through an existing narrowing, or deal with damage to the heart.

One example is coronary heart disease (CHD): fatty deposits narrow the coronary arteries, which supply the heart muscle with oxygen and glucose. Reduced blood flow can cause chest pain, and a blockage can lead to a heart attack. Treatment may aim to lower the chance of further disease, control symptoms or improve blood flow.
