title: Nonfearful panic disorder in chest pain patients.
abstract: The prevalence of non-fearful panic disorder (panic attacks without the experience of fear) was estimated in 199 patients consecutively referred to outpatient cardiac investigation for chest pain. Fifty-nine patients met the criteria for panic disorder, and 17 patients fulfilled the criteria for non-fearful panic disorder. The patients with non-fearful panic disorder had lower scores on self-reported panic symptoms and lower frequencies of agoraphobia and comorbid axis I disorders than the patients with panic disorder and had a higher prevalence of somatic disorders than the patients without panic disorder. The patients with non-fearful panic disorder did not differ significantly from the patients with panic disorder in health-related quality of life.
