Background: Non‐cardiac chest pain (NCCP) is a heterogeneous disorder. There is controversy about the associations between symptoms and causes in NCCP patients. The purpose of the present study was to evaluate the clinical usefulness of subgrouping according to characteristic symptoms in NCCP patients. Patients and Methods: Fifty‐eight patients were classified into two groups, as patients with typical reflux symptoms (group I, n = 24) and those without typical reflux symptoms (group II, n = 34). They underwent upper endoscopy, manometry, and 24‐h esophageal pH monitoring. Results: Twenty‐four (41%) of the patients were diagnosed with gastroesophageal reflux disease (GERD) at upper endoscopy or 24‐h esophageal pH monitoring. Eleven (19%) were diagnosed with GERD‐associated esophageal motility disorder and 13 (22%) were diagnosed with non‐GERD‐associated esophageal motility disorder. The two groups did not differ significantly in age, sex, weight, smoking history, history of chronic alcoholism, or the severity, duration and frequency of symptoms. The sensitivity, specificity, positive predictive value, negative predictive value, and likelihood ratio of group I for GERD‐related NCCP were significantly higher than those of group II. Group I had a higher proportion of patients with GERD‐associated esophageal motility disorder (55%) than non‐GERD‐associated esophageal motility disorder (23%). Conclusion: Typical reflux symptoms can be used to distinguish patients with GERD‐related NCCP from patients with NCCP, and subgrouping according to characteristic symptoms may assist the diagnosis of these patients in Korea.
