This is a result of plaque accumulation in one’s coronary arteries i.e. arteriosclerosis that leads to blockage. As a result heart receives less blood oxygen and vital nutrients required for proper pumping. Cholesterol laden plaque increases the risk of blood clots and heart attacks.

Fundamental nutrients passing through this vessel start sticking causing life threatening situation.Heart diseases are the number 1 cause of death globally. More people die annually from heart diseases than from any other disease.Thus ranked as the first of the top 10 worst diseases in the world.
