C. Shekhar; P. J. Whorwell, Evaluation and Management of Patients with Noncardiac Chest Pain
“ If the patient responds, then GERD-related chest pain is the most likely diagnosis and maintenance treatment may be required. Failure to respond to a PPI suggests that acid reflux is not the problem although obviously this does not exclude nonacid reflux. In the absence of reflux, it is usually assumed that the problem may be due to a disorder of motility or sensation. On the assumption that esophageal contractions may be contributing to the pain, a variety of treatments aiming at relieving spasm have been evaluated. ”
