Fig. 1. Upper gastrointestinal evaluation. Gastroesophageal reflux disease (GERD)-related noncardiac chest pain (NCCP) is found in 24 (41%) of 58 subjects on upper endoscopy and/or ambulatory 24-hour esophageal pH monitoring. Esophageal motility disorder is found in 24 subjects (41%), including 18 with ineffective esophageal motility, 4 with nutcracker esophagus, one with hypertensive lower esophageal sphincter (LES), and one with achalasia. GERD-associated esophageal dysmotility is found in 11 (19%) patients, and non-GERD-associated esophageal dysmotility is found in only 13 subjects (22%).

Non-GERD, non-GERD-related NCCP; Hyper LES, hypertensive LES; Nutcracker, nutcracker esophagus; IEM, ineffective esophageal motility.
