What is coronary heart disease?
CHD is the most common form of heart disease. It occurs when blood vessels to the heart fail to supply the necessary blood and oxygen to the working muscle of the heart. This is due to a narrowing of the small blood vessels, which normally supply the heart with blood and oxygen. The typical cause of this narrowing is a condition known as atherosclerosis, which is the result of plaque and fatty deposits building up on the artery walls, narrowing the vessels.
Cardiovascular diseases such as CHD can take years to reach a critical stage but early detection and prevention can literally be a lifesaver.
