[Antidepressant therapy in coronary artery disease].

Depression is considered an independent risk factor for coronary artery disease (CAD) and other vascular conditions. Moreover, comorbid depressive disorder in CAD patients carries an increased risk of cardiac events and mortality. Among survivors of acute myocardial infarction, up to 20% meet diagnostic criteria for major depression, the presence of which carries a fivefold increased risk of cardiac death within 6 months. Heart patients with depressive comorbidity require particular care for both adequate treatment of their affective disorder and reduction of their cardiac risk. Antidepressant treatment must follow established guidelines; special care is needed to avoid cardiac side effects. In this review, we discuss the pathophysiological and prognostic significance of comorbid depression in CAD and weigh risks and benefits of available treatment options - particularly different drug classes and psychotherapy - in light of recent study results.
