People with depression after heart attack 50% more likely to have stroke

People who have depression after a heart attack are nearly 50% more likely to suffer a stroke compared with those who don’t develop the mood disorder, new research suggests.

The study, presented April 2, 2022, at a conference of the American College of Cardiology, analyzed records from more than 495,000 patients across the United States who had a heart attack between 2015 and 2021.

About 10.5% were diagnosed with depression after their heart attack. One in six of these patients had been previously diagnosed with depression or another mental health disorder, while the others received a depression diagnosis only after the heart attack.

The heart attack survivors with depression also had higher rates of high blood pressure, diabetes, heart failure, chronic obstructive pulmonary disease (COPD), and coronary artery disease, compared with those who didn’t develop depression.

In addition, the depression patients had a higher average body mass index, and more of them were smokers. But researchers found the link between depression and higher stroke risk remained even after they adjusted the comparison to account for those factors.

Research findings presented at medical conferences should be considered preliminary until published in a peer-reviewed medical journal.

Still, this study built on evidence from earlier studies on the association between depression and stroke after heart attack. The researchers recommended that people who have had both heart disease and depression follow up regularly with their doctors.
