Depression contributes to the risk of heart disease more than genetics

Depression contributes to the risk of heart disease more than genetics, according to a long-term study of twins. Other research has found that depression makes people more susceptible to heart trouble. But recent studies have found some genes that increase the risk of heart disease may also make people more prone to depression. This study indicates that depression takes a huge toll on the heart that can't be due to genetics. (USA Today, 3/4/09)
