In search of associations between coronary artery disease and symptoms of depression and anxiety, we conducted a prospective cross-sectional study of 314 patients (age range, 19-79 yr) who had presented with chest pain. Coronary angiographic findings were classified into 5 categories (0-4), in which higher numbers indicated more severe disease. Symptoms of depression and anxiety were evaluated by the Beck depression and anxiety inventories, in which higher scores indicated more severe symptoms.
