Routine Screening for Depression in Patients With Coronary Heart Disease: Never Mind

A recent Science Advisory from the American Heart Association (AHA) recommended routine screening of all patients with coronary heart disease (CHD) for depression. The authors of the advisory noted that the high prevalence of depression in patients with CHD supports this strategy. A systematic review of the evidence on depression screening and treatment in CHD patients published soon after the AHA advisory found that screening tools for major depression are reasonably accurate among patients with CHD, but that the majority of patients who screen positive will not have major depression; that depression treatment in CHD patients only accounts for a small amount of variance in depression symptom change scores; and that there is no evidence that screening for depression improves CHD outcomes. We call for the AHA to reassess their recommendations in light of this systematic review and considering the potential impact of their document on clinical practice.
