Psychiatric care of patients with heart disease could be informed by the discovery of new genetic indicators, a recent study has revealed.
Up until now although it has been proved that individuals suffering from heart disease are twice as likely to develop depression, there has been no medical explanation for the phenomenon.
Researchers from the Miriam Hospital were therefore prompted to join forces with the Montreal Heart Institute, University of Montreal and McGill University to isolate genetic factors that they found contributed to depression in heart disease patients.
Dr Jeanne McCaffery, from the Miriam Hospital's Weight Control and Diabetes Research Center and assistant professor of psychiatry and human behavior at the Warren Alpert Medical School of Brown University was the lead author of the study.
She commented: "Our findings suggest that endothelial dysfunction may be a novel mechanism contributing to depressive symptoms among heart disease patients."
According to a report in the Daily Mail, post-natal depression can affect new fathers as well as mothers.
