Depression After a Heart Attack Dangerous for Years

The increased risk of death associated with depression after a heart attack persists for at least five years, a study finds.

"We've known for a number of years that depression increases the risk of mortality as well as morbidity [illness] after a heart attack for at least three to six months," said study author Robert M. Carney, a professor of psychiatry at Washington University School of Medicine in St. Louis. "We assumed that we would find a decline in risk, but that was not what we found. The risk remained worse after five years."

Carney and his colleagues followed more than 750 people after their heart attacks, according to their report in the current online issue of theJournal of Affective Disorders. Using diagnostic interviews rather than the self-reporting common in most such studies, the researchers determined that 163 had major depression, and 195 had minor depression. Over the five-year study, the death rate was 87 percent higher for those with major depression and 76 percent higher for those with any form of depression.
