Non-Cardiac Chest Pain (NCCP) is a term used to describe chest pain that resembles heart pain (also called angina) in patients who do not have heart disease. As the heart and esophagus are in close proximity, the pain due to both organs takes the same path to the brain. Thus, it becomes difficult to distinguish between cardiac pain and esophageal pain. This slide set gives a brief overview of the differentiating factors between GERD and NCCP.
