Health News Digest -- The number of Americans admitted to hospitals for treatment of coronary artery disease declined by 31 percent between 1997 and 2007, according to the latest News and Numbers from the Agency for Healthcare Research and Quality. In people with coronary heart disease, fatty deposits clog heart arteries, restricting the flow of blood to the heart and increasing the risk of a heart attack. As a result of this decrease, coronary heart disease no longer ranks as the leading disease treated in hospitals. It is now ranked number 3.
