Here are the facts. Coronary artery disease is the leading killer of men and women in Western civilization. In the United States alone, more than half a million people die of it every single year. Three times that number suffer known heart attacks. And approximately three million more have “silent” heart attacks, experiencing minimal symptoms and having no idea, until well after the damage is done, that they are in mortal danger. In the course of a lifetime, one out of every two American men and one out of every three American women will have some form of the disease.
