Published in the Journal of the American Medical Association, the findings suggest that depression contributes to heart disease indirectly - by fostering unhealthy behaviors like smoking - rather than directly. Certain biological factors linked with depression, such as inflammation and the levels of brain chemicals like serotonin, may play some role in heart health, researchers say, but the new study found that the factors that most increased heart disease risk in depressed people were the ones you might expect: lack of exercise and smoking...
