Panic disorder, cardiology patients, and atypical chest pain.

Although patients with angiographically normal coronary arteries have low mortality, several studies have indicated that their social and work morbidity is high. Panic disorder appears to be a major contributor to the continuing chest pain in this population. There are also many chest pain patients appearing in cardiology clinics who also do not have heart disease but who are not given the opportunity to be evaluated for psychiatric disorders. Among those presenting with atypical or nonanginal chest pain, panic disorder represents a likely etiologic consideration. The fact that such patients do exist in cardiology populations is further substantiated by an open-label trial of alprazolam which demonstrated a positive effect in patients selected from those with atypical chest pain and no heart disease found to fit panic disorder criteria. These findings strongly support the increasing affiliation between cardiology and psychiatry and reinforce the belief that many problems of the heart may be problems of the mind/brain.
