Abstract

Twenty-four-hour recording of esophageal pressure and pH was performed successfully in 41 patients admitted to the coronary care unit of a general hospital who had an episode of acute, prolonged retrosternal chest pain and who were initially suspected of suffering from coronary artery disease (severe angina pectoris, myocardial infarction), but in whom the pain was subsequently shown not to be of cardiac origin. The recordings were analyzed with fully automated techniques. A pain episode was considered to be related to abnormal esophageal motility when contraction amplitudes or durations in the pain episode exceeded the patient's upper limit of normal (97.5th percentile) or when the proportion of abnormal propagated contractions (simultaneous, nontransmitted) in the pain episode was significantly increased (χ2 test). Thirty patients (73%) had one or more pain episodes (in total 63 pain episodes) during the 24-hour recording. Forty-three percent of the pain episodes was related to abnormal motility and 30% to reflux, and 27% was not related to esophageal function disturbance. Using the criterium that the symptom index had to be ≥75%, it was found that the pain was related to reflux in 13 patients (43%) and to motor abnormalities in 10 patients (33%). It is concluded that in the majority of patients acutely admitted with noncardiac chest pain, esophageal motor abnormalities and reflux can be shown to be the likely cause of the symptoms.

      Most importantly, HRM rules out achalasia and other major esophageal motility disorders, which can present with symptoms that can resemble that seen with GERD [108]. In the context of non-cardiac chest pain, hypercontractile peristalsis, and other motor disorders, including achalasia may be encountered in some [109], while manometry is normal in 70% of these patients [110,111]. In refractory postprandial regurgitation, rumination or supragastric belching identified on HRIM may be the mechanism for symptoms [30,112,113], in as many as half of these refractory patients in a recent study [114].

      The diagnostic algorithm must have a high level of both sensitivity and specificity for the diagnosis of ACS. Of the patients who present to an ED with chest pain, 30-58% are subsequently diagnosed with gastro-oesophageal reflux disease (GERD) or oesophageal motility disorders [6–9]. Distinguishing ischaemic from oesophageal chest pain can be difficult on patient history and clinical observation, as both ischaemic cardiac chest pain and the pain associated with GERD can share very similar characteristics, including dyspepsia, and a response to nitrates or an antacid cocktail [10,11].

      It has been shown that up to 40% of the patients, admitted to a coronary care unit with typical angina-like chest pain have a normal coronary anatomy [3]. The majority of their chest pain events might, however, be caused by gastro-oesophageal reflux disease or other oesophageal motility disorders as it has been established by functional oesophageal testing [4–10]. Furthermore, oesophageal causes of non-cardiac chest pain can also be observed in patients with coronary artery disease with a similar incidence [11–13].
