Abstract

Background

The development and course of noncardiac chest pain are assumed to be influenced by interoceptive processes.

Purpose

It was investigated whether heartbeat perception was enhanced in patients suffering from noncardiac chest pain and to what degree it was associated with self-reported cognitive–perceptual features and chest pain characteristics.

Methods

A total of 42 patients with noncardiac chest pain (NCCP), 35 patients with cardiac chest pain, and 52 healthy controls were recruited. Heartbeat perception was assessed using the Schandry task and a modified Brener–Kluvitse task. Self-report measures assessed anxiety sensitivity, somatosensory amplification, heart-focused anxiety, and chest pain characteristics.

Results

Heartbeat perception was not more accurate in patients with NCCP, compared to patients with cardiac chest pain and healthy controls. However, in patients with NCCP, the error score (Schandry task) was significantly associated with stronger chest pain impairment, and the response bias (Brener–Kluvitse task) was associated with lower chest pain intensity.

Conclusion

Against assumptions of current etiological models, heartbeat perception was not enhanced in patients with NCCP. Chest pain characteristics and particularly their appraisal as threatening might be more relevant to NCCP than the perceptional accuracy of cardiac sensations and should be focused in psychological interventions. However, associations with chest pain impairment suggest cardiac interoception to influence the course of NCCP.
