Depression and coronary artery disease are known to walk hand in hand, but a new study suggests that depression any time after a diagnosis of CAD is the strongest predictor of death.
Among 24,137 patients identified with significant CAD, a new depression diagnosis was associated with a twofold higher risk of all-cause death after multivariable adjustment, the investigators reported in the European Heart Journal Quality of Care and Clinical Outcomes.
"It was stronger than any follow-up events, stronger than diabetes, stronger than smoking, sex, prior diagnosis of high blood pressure or depression, and even whether they had a heart attack," lead author Dr Heidi T May (Intermountain Heart Institute, Murray, UT) told theheart.org | Medscape Cardiology. "I thought it would be a significant predictor, but I didn't anticipate it would be the strongest.
"I would think most people would find that amazing."
