New link between depression and heart disease (Canada)

Researchers have identified an enzyme that may trigger depressive symptoms in patients with heart disease and may help to explain why general antidepressants are often not as effective for these specific patients. "Our study confirms that depressive symptoms are associated with inflammation in patients with heart disease and suggests a mechanism by which the brain might be affected," says Walter Swardfager, lead author of a new study and PhD candidate in the Neuropsychopharmacology Research Program at Sunnybrook Health Sciences Centre, Canada
