Esophageal motility patterns in patients with and without coronary heart disease and healthy controls.

Background/aims: The aim of the study was to evaluate esophageal motility patterns in patients with chest pain with and without coronary artery disease, in order to elucidate the question: Does "non-cardiac" chest pain really exist?

Methodology: Patients with chest pain and normal coronary angiograms, patients with chest pain and coronarographically diagnosed coronary artery disease and controls were prospectively studied with long-term manometry.

Results: The pressure amplitudes were 38.3 (NCA)/39.
