The prevalence of anxiety disorders among patients with mitral valve prolapse syndrome and chest pain.

Nineteen patients from a cardiology practice with complaints of chest pain and with mitral valve prolapse syndrome were compared with 26 patients with chest pain but no discernible cardiac disorder. Instruments included a truncated form of the Diagnostic Interview Schedule, the symptom checklist 90 revised (SCL-90-R), the McGill Pain Questionnaire, and life events, physical activity, and family history questionnaires. Neither panic disorder nor self-rated anxiety were more common in the mitral valve prolapse group. This study failed to confirm the reported high association between mitral valve prolapse syndrome and panic disorder.
