(Ivanhoe Newswire) -- Heart disease patients diagnosed with
depression could be in double trouble. New research shows these patients are
at an increased risk of heart failure after a diagnosis of depression.
In a recent study, researchers found depression diagnosis following coronary
artery disease (CAD) was associated with a two-fold increased risk for the
incidence of heart failure.
"Interestingly, when we stratified patients with depression by whether they
received antidepressant medication or not, the incidence of heart failure
didn't change,” Heidi May, Ph.D., M.S.P.H., an epidemiologist at
Intermountain Medical Center in Murray, Utah, was quoted as saying. “This
finding may indicate that antidepressants may not be able to alter the
physical or behavioral risks associated with depression and heart failure,
despite a potential improvement in depressive symptoms."
Researchers note there are overlapping risk factors between depression and
heart failure, including smoking, hypertension, diabetes and being
overweight. Other studies have also linked depression to neglecting good
health habits and adhering to medical treatment, all of which could
contribute to the results of this new study. The researchers say their
findings suggest careful screening for depression among CAD patients.
