Understanding Coronary Heart
Disease
The heart is a strong and powerful organ. It pumps blood
throughout the body, which supplies oxygen and nutrients to
all other organs and tissues.
The coronary arteries are the blood vessels around the heart.
They are responsible for supplying blood to the heart itself
to ensure that the blood circulation and the heart functions
normally.
Coronary heart disease (CHD) is caused by the narrowing or
blockage of the coronary arteries. This reduces the smooth
flow of blood and, therefore, interferes with the delivery
of adequate oxygen supply and nutrients to the heart muscle.
In severe cases, this can lead to damage of the heart muscle
and even death.
