Non-cardiac chest pain is a term used to describe chest pain that resembles heart pain (also called angina) in patients who do not have heart disease. The pain typically is felt behind the breast bone (sternum) and is described as oppressive, squeezing or pressure-like. This can be caused by a variety of factors including gastroesophageal reflux, esophageal motility disorders, and/or biliary and pancreatic disorders.
