Depressed CAD Patients May be at Higher Risk For MI, Death

Patients with coronary artery disease (CAD) who are depressed may have a much higher risk of myocardial infarction (MI) or death compared to those who are not depressed, according to research published March 23 which will be presented at ACC.16 in Chicago.

The study, conducted by Natalie Szpakowski, MD, and colleagues, included 22,917 patients who had been diagnosed with stable CAD following a coronary angiogram for chest pain. Results showed that the incidence of depression following a diagnosis of stable CAD was 18.8 percent. Patients who were female or who had more severe angina were more likely to be diagnosed with depression.

Further, depressed CAD patients were 83 percent more likely to die from any cause compared to those who were not depressed. They were also 36 percent more likely to present at a hospital for MI.  Those who were diagnosed with depression 90 to 180 days following the diagnosis of CAD were at greatest risk.

According to the authors, these findings suggest that these patients may need to be screened for mood disorders, either by their family physician or their cardiologist.

“Based on these findings, there may be an opportunity to improve outcomes in people with coronary heart disease by screening for and treating mood disorders, but this needs to be further studied,” says Szpakowski. “Stable chronic angina due to narrowing of the coronary arteries is common, and our findings show that many of these patients struggle with depression. Our follow-up was at most five years, so many more might be affected.”
