title: Oesophageal ischaemia in motility disorders associated with chest pain.
abstract: The cause of chest pain in diffuse oesophageal spasm and "nutcracker" oesophagus is not clear. Spasm of the oesophageal muscle itself is probably not the cause, because pain and spasm are frequently not coincident. It is suggested instead that oesophageal ischaemia may be the cause of the pain, since the rewarming rate of the oesophagus after a standardised cold challenge was significantly longer in 9 patients with these motility disorders than in 21 normal controls. As rewarming time in other sites correlates with blood flow, these results are consistent with the hypothesis that the oesophagus is ischaemic in these patients.
