According to a recent study depressed people have an increased risk of atrial fibrillation or an irregular heart rate that commonly causes poor blood flow. Researchers at Aarhus University also found that medication was not responsible for the high frequency of atrial fibrillation in depressed people. The findings are published in the European Journal of Preventive Cardiology. It is common knowledge that there is a connection between the mind and the heart. Depression predicts the development of coronary artery disease and worsens its prognosis. Our study investigated whether depression is also linked with atrial fibrillation said study's author Morten Fenger-Grøn.
