Depressive Symptoms and Associated Risk Factors In Coronary Artery Disease Patients Heather L. Rogers, Mariantonia Lemos Hoyos, Verónica Cuartas Murillo & Juan Carlos
99 patients with Coronary Artery Disease (CAD) from the Cardiovascular Clinic and 107 healthy controls in Medellín, Colombia were administered the Patient Health Questionnaire – 9 (PHQ-9, measure of depression) and answered questions regarding presence of traditional CAD risk factors. CAD patients had significantly higher PHQ-9 scores compared to controls. For each point on the PHQ-9, the risk of having CAD increased by 12% [OR=1.12 (1.04-1.21)]. Using multiple logistic regression models, hypertension and former smoking were found to mediate the relationship between depressive symptoms and CAD. Although there is a relationship between depressive symptoms in the prior two weeks and CAD, hypertension and former smoking are important mechanisms that explain this relationship in this sample of Colombians.
