As a result, heart works harder to pump oxygen rich blood to the entire body. When it gets exhausted, it results in chest pain called Angina technically. It also causes abnormality in the beating of organ.

When the plaque completely closes the pathways arteries and veins, fatal condition called heart attack is caused. In the case of brain, when its pathways are blocked through which oxygen rich blood and glucose are supplied, it results in stroke.
