Write answer in between .Q:A previously healthy 57-year-old man comes to the emergency department because of acute retrosternal chest pain that radiates to his back. The pain started suddenly while he was having dinner. A few moments prior to the onset of the pain, he experienced discomfort when trying to eat or drink anything. On the way to the hospital he took a sublingual nitrate tablet that he had at home, which helped relieve the pain. His pulse is 80min, respirations are 14min, and blood pressure is 14488 mm Hg. Examination shows no other abnormalities. An ECG shows a normal sinus rhythm with no ST-segment abnormalities. An esophagogram is done and shows areas of diffuse, uncoordinated spasms in several segments along the length of the esophagus. This patients condition is most likely to show which of the following findings?? A: Esophageal manometry shows simultaneous multi-peak contractions, B: Endoscopy shows multiple mucosal erosions, C: Ultrasonography shows a mass at the gastroesophageal junction, D: Serology shows elevated CK-MB levels, E: Esophageal manometry shows hypertensive contractions,  <response>: This is a clinical vignette describing a patient with acute onset chest pain that radiates to the back and is relieved by nitrates. Key findings include onset during eating, normal ECG and vital signs. The esophagogram shows diffuse spasms along the esophagus. Based on the acute onset during eating, relief with nitrates, normal cardiac workup and esophageal spasms on imaging, this is most consistent with esophageal spasm or diffuse esophageal spasm. Esophageal manometry would be expected to show simultaneous multi-peaked contractions, while the other findings would not be expected.A: Esophageal manometry shows simultaneous multi-peak contractions
