Cardiovascular diseases rank as America's number 1 killer. They claim the lives of
             42.7 percent of the more than 2 million Americans who die each year. Cancer follows,
             killing 23.8 percent. All other causes of death account for 33.5 percent. Medical research
             continually seeks to reduce disability and death from heart attack, stroke and other heart
             and blood vessel diseases. However, more than 56 million Americans heart defects to
             high blood pressure and hardening of the arteries. As a result, Americans will pay an
             estimated $128 billion in 1955 for medical cost and disability. Especially costly to
             American business are the deaths of skilled employees between the ages of 35 and 64,
             where the loss of management and production skills and the cost of training replacement
             The human heart is a muscle that pumps blood. Blood containing food and oxygen
             to meet the heart's own needs come from the coronary arteries. Fatty deposits (called
             Plaque) made of cholesterol and other substances can build up in the walls of these
             vessels. Over time such deposits marrow the arteries are reduce or stop blood flow to the
             heart. This may cause chest pain called angina pectoris. When less blood flows to the
             heart, the heart muscle may be damaged. If a blood clot forms in a narrowed artery and
             completely blocks the blood flow, part of the heart may die. Doctors call this a hear
             attack of a coronary thrombosis, coronay occlusion or mycardial infarction. If the heart
             can be kept beaten, and the heart muscle isn't too damaged, small blood vessels may
             gradually reroute blood around blocked arteries.
             Uncomfortable pressure, fullness, squeezing or pain in the center of the chest that
             last more than a few minutes could mean a heart attack, particularly if the pain spreads to
             the shoulders, neck or arms. Lightheadedness, fainting, sweating, nausea of shortness of
