Enduring Depression Linked to Increased Coronary Artery Calcification Among Women
Major depressive disorder is a highly disabling condition that affects nearly 15 million American adults in a given year.
HealthDay News — Persistent depressive symptoms are associated with increased coronary artery calcium (CAC) scores among middle-aged women without cardiovascular disease (CVD), according to a study published in The American Journal of Cardiology.
Imke Janssen, PhD, from the Rush University Medical Center in Chicago, and colleagues assessed participants in the Study of Women's Health Across the Nation Heart study annually for depressive symptoms over 5 years before CAC assessment.
The researchers found that high depressive symptoms were common over 5 years in middle-aged women free from CVD and diabetes: 19% had 1, 9% had 2, and 11% experienced 3 or more episodes. Overall, CAC was low, with 54%, 25%, and 21% having no CAC, 0 to 10, and ≥10 Agatston units, respectively. Compared to women with no depressive episodes, women with 3 or more episodes were twice as likely to have significant CAC (≥10 Agatston units), after adjustment for CVD risk factors (odds ratio, 2.20), with no difference by race. There was no difference for women with one or two episodes versus no episodes.
"In healthy women aged 46 to 59 years without clinical CVD or diabetes, persistent depressive symptoms were significantly associated with elevated CAC scores, suggesting that they are more likely to have pathophysiological and behavioral effects on the development of subclinical CVD than does a single episode of elevated depressive symptoms," the authors write.
