MAJOR DEPRESSION AND AGORAPHOBIA IN PATIENTS WITH ANGIOGRAPHICALLY NORMAL CORONARY-ARTERIES AND PANIC DISORDER

Patients with panic disorder and/or agoraphobia appearing to psychiatric settings report rates for lifetime major depression between 24% and 91%. Between 40% and 90% of patients with panic disorder in psychiatric populations report concomitant agoraphobia. A recent study of panic disorder subjects appearing in an outpatient cardiology clinic confirmed the strong link between panic and depression but found only a weak association between panic disorder and agoraphobia. In order to test the reliability of these outpatient cardiology findings, the authors studied major depression and agoraphobia in patients with angiographically normal coronary arteries and panic disorder. Twelve of the 32 (37.5%) panic disorder subjects reported a lifetime history of major depression (nine current, three past only). Only two of the 32 (six percent) reported any phobic avoidance. This study confirms the previous findings which suggest that major depression is common in cardiology populations with panic disorder and that phobic avoidance is uncommon in this group.
