Have a Good Heart


Tuesday, September 23rd, 2008 Have a Good Heart

There is strong evidence to support that Coronary Heart Disease is the biggest killer in the UK. However with the onset of new technologies and treatments as a population we can prolong our lives. Though essentially we need to know what the heart is to gain understanding of its value.

The heart is a muscle that is about the size of your fist. It pumps blood around your body and beats approximately 70 times a minute. After the blood leaves the heart, it goes to your lungs where it picks up oxygen.

The oxygen-rich blood returns to your heart and is then pumped to the organs of your body through a network of arteries. The blood returns to your heart through veins before being pumped back to your lungs again. This process is called circulation.

The heart gets its own supply of blood from a network of blood vessels on the surface of your heart, called coronary arteries.The heart gets its own supply of blood from a network of blood vessels on the surface of your heart, called coronary arteries.

One of the commonest diseases to affect the heart is coronary heart disease (CHD). It’s usually caused by atherosclerosis, a build up of fatty materials within the walls of the arteries.In CHD, the arteries that supply the heart with oxygen and nutrients become narrowed by atherosclerosis. This restricts the supply of blood and oxygen to the heart, particularly during exertion when there are more demands on the heart muscle.
