Cognitive/behavioral therapy of anxiety in the medically ill: cardiac settings.

Anxiety appears to be a strong risk factor for ischemic heart disease (IHD) and specifically fatal IHD. However, no randomly assigned, controlled, clinical trial targeting anxiety yet exists demonstrating an impact on objective cardiac outcomes. Situational anxiety is frequent in cardiac populations and can diminish quality-of-life by increasing symptoms/disability and result in unnecessary medical system utilization. "Noncardiac" chest pain is common both in patients with objective coronary disease and in patients whose cardiac workup is negative. Both presentations of chest pain respond to cognitive/behavioral therapy, and imipramine has been found to be effective for chest pain unaccompanied by coronary disease. Because anxiety-like symptoms overlap with symptoms of IHD (eg, chest pain, dyspnea, dizziness, palpitations) and can be caused by organic factors, the diagnosis and treatment of anxiety in these populations require special considerations.
