Exercise May Reduce Subclinical Heart Disease Symptoms in People With Depressive Symptoms

A population study published today in the Journal of the American College of Cardiology points to a link between depressive symptoms and early biological indicators of heart disease, and highlights the potential for physical exercise to attenuate this risk.

Researchers from Emory University evaluated 965 adults (average age 49) who were free of any cardiovascular disease and had no history of an affective, psychotic, and/or anxiety disorder. All the patients completed a Beck Depression Inventory-II (BDI-II) questionnaire and underwent tests of their vascular function.

Subsequent analysis found that even when considering other factors associated with heart problems such as age, weight, or hypertension, higher BDI-II scores were associated with early cardiovascular disease (CVD) indicators like arterial stiffening and inflammation.

There was a significant interaction between these indicators and exercise, with sedentary individuals showing more severe arterial stiffening and inflammation, while these symptoms were attenuated in physically active people.

“Subjects undertaking regular exercise have a lower burden of subclinical CVD markers even in the presence of depressive symptoms,” the study authors wrote. “Our findings highlight potential mechanisms by which depressive disorders are linked to CVD risk and support routine assessment of depressive symptoms to improve CVD risk stratification.”
