Psychological symptom profiles in patients with chest pain

Five-hundred and thirty-two patients with ischaemic-like chest pain referred for symptom-limited exercise thallium myocardial perfusion studies, were assessed on a range of psychosocial measures. Three groups of patients were identified on the basis of their perfusion studies: (1) normal thallium perfusion; (2) current myocardial ischaemia; and (3) past myocardial infarction (but no current ischaemia). There were no significant psychological differences between these groups on a wide range of measures which included depression, state and trait anxiety, Type A behaviour, personality, suppression of affect, locus of control, alexythymia, and hypochondriasis. Significant differences were identified, however, on measures of anger and coping style. Subjects with no current ischaemia (normal thallium perfusion and those with past myocardial infarction) had higher scores on 'immature coping' and 'anger in', than subjects with current myocardial ischaemia. These findings are discussed in the light of other published research.
