             Obesity increases the likelihood of developing high blood cholesterol and high blood pressure. CHD is caused by the thickening of the inside walls of the coronary arteries. This thickening is called atherosclerosis, narrows the space through which blood flows decreasing of cutting off the heart's oxygen and nutrient supply. Atherosclerosis usually occurs when a person has high levels of cholesterol (usually obese people), in the blood. .
             When cholesterol level in the blood is high, there is greater chance that it will be deposited onto the artery walls, thus narrowing the arteries and can slow or block blood flow. .

             Coronary / Balloon angioplasty - inflation of a tiny balloon at the tip of the catheter positioned in the narrowed coronary artery.
             Coronary bypass operation - blood vessel taken from leg or chest is grafted onto the blocked artery, bypassing the blocked area.
             Atherectomy - procedure whereby surgeons shave off thin strips of plaque blocking the artery and remove these strips.
             Laser angioplasty - use of a catheter with a laser to burn the plaque in a blocked artery.
             Insertion of a stent, a metal coil that can be permanently implanted in a narrowed part of the artery to keep it propped open.
