In coronary heart disease layers of fatty material build up inside the coronary arteries. This reduces the flow of blood through the coronary arteries. This can lead to a heart attack
Statins are widely used to reduce blood cholesterol levels, which slows down the rate of fatty material deposit.
Stents are used to keep the coronary arteries open.
In some people heart valves may become faulty, preventing the valve from opening fully, or the heart valve might develop a leak
Faulty heart valves can be replaced using biological or mechanical valves.
In the case of heart failure, a donor heart, or heart and lungs, can be transplanted. Artificial hearts are occasionally used to keep patients alive whilst waiting for a heart transplant, or to allow the heart to rest as an aid to recovery
