The present study was performed to compare pain-related oesophageal motility, gastro-oesophageal reflux and ST-segment deviations in patients with intermittent chest pain and normal or pathological coronary angiography. Thirty patients (11 males, 19 females; mean age 54.8 years) with normal and 15 patients (12 males, 3 females; mean age 66.7 years) with pathological coronary angiography were investigated by 24-h oesophageal pressure, pH and ECG recording. Chest pain correlated with motility abnormalities or gastro-oesophageal reflux occurred in 33% (10/30) of patients with normal coronary arteries and in 26% of patients with pathological coronary angiography. Symptomatic and asymptomatic ST-segment changes were less frequently observed in patients with normal angiography (4/30) than in patients with pathological coronary angiography (7/14; P = 0.02). Oesophageal dysfunction coincided with ST-segment deviation in 6.7% (2/30) of patients with normal and 40% (6/15) of patients with pathological coronary angiography (P = 0.02). The conclusions reached were: (1) pain-correlated abnormal motility or gastro-oesophageal reflux occurred in patients with normal and pathological coronary angiography at the same frequency; (2) ambulatory motility and pH recording alone does not appear to differentiate between cardiac and non-cardiac chest pain; (3) simultaneous ECG recording reveals a significant correlation of ST-segment deviation and gastro-oesophageal reflux or abnormal motility in patients with coronary artery stenosis.
