Every organ in the human body needs a continuous supply of oxygen and nutrients for survival, and heart is no exception. This supply of oxygen and other nutrients happens by circulation of blood, and heart pumps and puts the blood into motion.
Although the heart contains blood inside its cavity, it does not use it to for its survival, instead, it depends on coronary arteries.
There are two coronary arteries in the human body, namely, left and right coronary arteries. Left coronary divides into further major branches LAD and LCX.
A disease process knows as atherosclerosis can affect any vessel in the human body so can affect coronary arteries. Atherosclerosis produces plaques inside the blood vessels thus limiting the flow of blood.
This flow limitation can jeopardise the functioning of the organ affected. If the flow limitation is severe it can even cause the death of part of an organ, leading to catastrophes. Consequences depend on the organ and amount of tissue affected. For example, if the block is for lower limb then subject may lose is a limb, if the blocked vessels is supplying the brain then subject may suffer brain stroke.
Similarly, if the block affects coronary arteries it leads to heart attack.
