Besides being the top cause of death in the United States, heart disease has now been linked to higher depression incidence.

After reviewing dozens of studies, researchers from the UCSF School of Nursing and Medicine found that depression was three times more likely to occur among the people who had suffered heart attack when compared with the general population. It was young women who were especially vulnerable to depression following a heart attack.

American Heart Association has also observed said that people hospitalized for conditions such as unstable angina, angioplasty, bypass surgery or valve surgery were as likely as those who'd had an outright heart attack to develop depression.

If any of the cardiac patients has recently felt little interest or pleasure in doing things or felt down, depressed or hopeless, they should seek professional help for further evaluation. Treatment could range from medication to exercise to cognitive behavioral therapy.

Depression is also very likely to lead to heart attacks since people suffering from depression may not be exercising and eating well, or may smoke.
