When a person acquires coronary artery disease (CAD), this condition causes the arteries to narrow or become smaller than their original size. CAD is caused by the accumulation of fatty acids, cholesterol, and calcium. And other substances are present inside the walls of the arteries. Therefore, doctors opted for the heart bypass surgery procedure to improve heart health of the person.
