Cognitive therapy for depression in patients with heart failure: a critical review.

Depression is a significant problem in patients with heart failure (HF). This article examines the evidence for the use of cognitive therapy (CT) in treating depression and depressive symptoms in patients with HF and cardiovascular related illnesses. In 8 of the 14 studies reviewed, researchers found that CT reduced depressive symptoms; however, the limitations of the studies prevent wide generalization of the results. Evidence to support the use of CT for the treatment of depressive symptoms in patients with cardiovascular illness is insufficient at this time. Large randomized controlled trials that demonstrate the efficacy of CT are needed before clinicians routinely refer patients with HF to CT for the purpose of improving depression or depressive symptoms.
