BOSTON — Recovering from a heart attack is tough enough without facing depression. Yet that's exactly what happens to nearly half of heart attack survivors. Depression after a heart attack isn't a one-size-fits-all classification. Different variations have different effects on the heart and recovery, reports the April 2007 issue of the Harvard Heart Letter.

Depression that occurs for the first time during recovery from a heart attack appears to be more dangerous than depression that started before the attack.
Depression arises for various reasons. In some people, depression and heart disease may reflect a genetic vulnerability that can trigger both conditions.
