Is there a high-risk subtype of depression in patients with coronary heart disease?

Abstract

Depression is a risk factor for cardiac morbidity and mortality in patients with coronary heart disease, especially in those with a recent history of acute coronary syndrome. To improve risk stratification and treatment planning, it would be useful to identify the characteristics or subtypes of depression that are associated with the highest risk of cardiac events. This paper reviews the evidence concerning several putative depression subtypes and symptom patterns that may be associated with a high risk of morbidity and mortality in cardiac patients, including single-episode major depressive disorder, depression that emerges after a cardiac event, somatic symptoms of depression, and treatment-resistant depression.
