Like all organs, your heart is made of tissue that requires a supply of oxygen and nutrients. Although its chambers are full of blood, the heart receives no nourishment from this blood. The heart receives its own supply of blood from a network of arteries, called the coronary arteries.
Two major coronary arteries branch off from the aorta near the point where the aorta and the left ventricle meet:
- Right coronary artery supplies the right atrium and right ventricle with blood. It branches into the posterior descending artery, which supplies the bottom portion of the left ventricle and back of the septum with blood.
- Left main coronary artery branches into the circumflex artery and the left anterior descending artery. The circumflex artery supplies blood to the left atrium, side and back of the left ventricle, and the left anterior descending artery supplies the front and bottom of the left ventricle and the front of the septum with blood.
These arteries and their branches supply all parts of the heart muscle with blood.
What happen if you don’t take care ?
Coronary artery disease will occur when plaque builds up in the coronary arteries and prevents the heart from getting the enriched blood it needs. If this happens, a network of tiny blood vessels in the heart that aren’t usually open called collateral vessels may enlarge and become active. This allows blood to flow around the blocked artery to the heart muscle, protecting the heart tissue from injury. Sometimes these vessel gets blocked and cause a heart attack.
What Is A Heart Attack?
Most heart attacks are the result of coronary heart disease, a condition that clogs coronary arteries with fatty, calcified plaques. Researchers confirmed that the immediate cause of nearly all heart attacks is not the obstructive plaque itself. Instead, it’s the sudden formation of a blood clot on top of plaque that ruptures and subsequently cuts off blood flow in an already narrowed blood vessel.
