Biomed Pharmacother 2023; 167:115523. [PMID: 37742610 DOI: 10.1016/j.biopha.2023.115523] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2023] [Revised: 09/05/2023] [Accepted: 09/14/2023] [Indexed: 09/26/2023] Open
Abstract
BACKGROUND Proton-pump inhibitors (PPI) are frequently used in the emergency and general practice settings in several clinical presentations linked to acute upper gastro-intestinal tract disorders as abdominal or chest pain without recommendations. OBJECTIVE The aim of this scoping review was to assess pain reduction, diagnostic performance, and safety in the first 24 h-management in primary care or emergency medicine. METHODS Search was realized by 2 independent reviewers in PubMed, Embase, and Web of Science following PRISMA-ScR guidelines. Only original articles or systematic reviews in English were included. Studies about chronic and/or bleeding conditions, therapeutic cocktails and studies without pain evaluation were excluded. Two methodologies were used for bias estimation. RESULTS From 4442 titles, 79 full-text articles were assessed, and 9 were included. There is no strong evidence supporting the use of PPI as a first line analgesic or diagnostic test in acute syndromes linked to acute upper gastro-intestinal tract disorder. A small effect in pain reduction was retrieved in patients with low pain scores. A poor additional value in patients with gastric reflux, and a low specificity compared to other diagnostic tests were observed. A short-term PPI administration appears to be safe with low risk of serious allergic reactions, and poor adverse effects (moderate evidence). CONCLUSION Although PPIs may contribute to the multimodal analgesia in acute settings, with few and/or minor side effects, no recommendation can be drawn for their use as a primary analgesic. Data regarding the relevance of the PPI test are much less clear, no data regarding care pathways are available.

Clinical usefulness of esophageal high resolution manometry and adjunctive tests: An update. Dig Liver Dis 2021; 53:1373-1380. [PMID: 33994122 DOI: 10.1016/j.dld.2021.04.007] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/20/2021] [Revised: 04/07/2021] [Accepted: 04/08/2021] [Indexed: 12/11/2022]
Abstract
High resolution manometry (HRM), developed from conventional manometry, is the gold standard for assessment of esophageal motor function worldwide. The Chicago Classification, now in its fourth iteration, is the modern standard for HRM categorization of esophageal motility disorders. The HRM protocol has expanded from the original 10 supine swallow standard, to include upright swallows, and provocative maneuvers such as multiple rapid swallows, rapid drink challenge and standardized test meal. Impedance has been incorporated into HRM for visualization of bolus clearance. Futhermore, barium radiography and functional lumen imaging probe complement HRM when evidence of esophagogastric junction obstruction is inconclusive. The biggest impact of HRM is in the improved diagnosis and subtyping of achalasia spectrum disorders, with implications on management. Spastic disorders and absent contractility are better characterized. Within the reflux spectrum, HRM provides definition of morphology and tone of the esophagogastric junction, and assesses integrity of esophageal body peristalsis, which have pathophysiologic implications for reflux and its clearance. HRM provides characterization of behavioral disorders such as supragastric belching and rumination syndrome, which can mimic reflux disease. Thus, HRM has revolutionized the evaluation of esophageal motor function, and has expanded the utility of esophageal manometry in clinical practice.

ESNM/ANMS consensus paper: Diagnosis and management of refractory gastro-esophageal reflux disease. Neurogastroenterol Motil 2021; 33:e14075. [PMID: 33368919 DOI: 10.1111/nmo.14075] [Citation(s) in RCA: 36] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/27/2020] [Revised: 11/11/2020] [Accepted: 12/13/2020] [Indexed: 02/08/2023]
Abstract
Up to 40% of patients with symptoms suspicious of gastroesophageal reflux disease (GERD) do not respond completely to proton pump inhibitor (PPI) therapy. The term "refractory GERD" has been used loosely in the literature. A distinction should be made between refractory symptoms (ie, symptoms may or may not be GERD-related), refractory GERD symptoms (ie, persisting symptoms in patients with proven GERD, regardless of relationship to ongoing reflux), and refractory GERD (ie, objective evidence of GERD despite adequate medical management). The present ESNM/ANMS consensus paper proposes use the term "refractory GERD symptoms" only in patients with persisting symptoms and previously proven GERD by either endoscopy or esophageal pH monitoring. Even in this context, symptoms may or may not be reflux related. Objective evaluation, including endoscopy and esophageal physiologic testing, is requisite to provide insights into mechanisms of symptom generation and evidence of true refractory GERD. Some patients may have true ongoing refractory acid or weakly acidic reflux despite PPIs, while others have no evidence of ongoing reflux, and yet others have functional esophageal disorders (overlapping with proven GERD confirmed off therapy). In this context, attention should also be paid to supragastric belching and rumination syndrome, which may be important contributors to refractory symptoms.

Abstract
High-resolution manometry revolutionized the assessment of esophageal motility disorders and upgraded the classification through the Chicago Classification. A known disadvantage of standard HRM, however, is the inability to record esophageal motility function for an extended time interval; therefore, it represents only a more snapshot view of esophageal motor function. In contrast, ambulatory esophageal manometry measures esophageal motility over a prolonged period and detects motor activity during the entire circadian cycle. Furthermore, ambulatory manometry has the ability to measure temporal correlations between symptoms and motor events. This article aimed to review the clinical implications of ambulatory esophageal manometry for various symptoms, covering literature on the manometry catheter, interpretation of findings, and relevance in clinical practice specific to the evaluation of non-cardiac chest pain, chronic cough, and rumination syndrome.

Abstract
BACKGROUND High-resolution esophageal manometry (HREM) has become a leading tool in the assessment of esophageal motor disorders, replacing conventional manometry. However, there is limited data about the contribution of HREM as compared with conventional manometry to the assessment of esophageal motor disorders in patients with non-cardiac chest pain (NCCP). The aim of the study was to compare the distribution of esophageal motor disorders in patients with NCCP using HREM as compared with conventional manometry and to determine if HREM improved diagnosis of these disorders. METHODS In this study, we included 300 consecutive patients with NCCP who underwent either HREM or conventional manometry over a period of 10 years. A total of 150 patients had conventional manometry and the other 150 patients HREM. The Chicago 3.0 classification and the Castell and Spechler classification were used to determine the esophageal motor disorder of NCCP patients undergoing HREM and conventional manometry, respectively. KEY RESULTS In both HREM and the conventional manometry groups, normal esophageal motility was the most frequent finding (47% and 36%; respectively, P = .054). Hypotensive lower esophageal sphincter was the most common motility disorder identified by conventional manometry (27.3%), while ineffective esophageal motility was the most common esophageal motor disorder identified by HREM (25.3%). CONCLUSIONS & INFERENCES There is a discrepancy in the type of esophageal motor disorders identified by HREM as compared with conventional manometry in NCCP patients. Hypotensive motility disorders are the most commonly diagnosed by both manometric techniques.

Abstract
Fluoroscopic esophagography is a widely available, safe, and inexpensive test for detecting gastroesophageal reflux disease. In this article, we review the technique for performing a high-quality esophagram, including upright, double-contrast views of the esophagus and cardia with high-density barium; prone, single-contrast views of the esophagus with low-density barium; and evaluation of gastroesophageal reflux. We then discuss the radiographic findings associated with gastroesophageal reflux disease, including esophageal dysmotility, reflux esophagitis, peptic strictures, and Barrett's esophagus. Finally, we consider the differential diagnosis for the various radiographic findings associated with this condition. When carefully performed and interpreted, the esophagram is a useful test for evaluating gastroesophageal reflux disease and its complications.

Abstract
Background/Aims Gastroesophageal reflux disease (GERD) is the most common cause of non-cardiac chest pain (NCCP). Currently available data reveal a weak relationship between NCCP and dysmotility. Moreover, it is unclear why some refluxes are perceived as heartburn and others as NCCP. We aimed to evaluate the role of the reflux pattern and the esophageal motility in patients with NCCP. Methods Forty-eight patients with NCCP (Group 1) and 50 only typical GERD symptoms (Group 2) were included and underwent high-resolution manometry (HRM) and multichannel intraluminal impedance-pH monitoring. Results Impaired peristalsis was found in 60% of patients with NCCP and in 24% of patients with typical symptoms (P < 0.05). In patients belonging to Group 1, the majority of reflux episodes associated with chest pain were acid and mixed. The proportion of mixed refluxes was higher than that in Group 2. In Group 1, the reflux clearing time at 5, 9, and 15 cm, measured in reflux episodes associated to NCCP was longer than in reflux episodes associated to typical symptoms (mean ± 95% CI: 27.2 ± 5.6, 23.3 ± 4.4, and 14.6 ± 2.3 seconds vs 18.3 ± 3.5, 13.3 ± 2.2, and 11.1 ± 1.8 seconds; P < 0.01). Conclusions The presence of gas in the refluxate seems to be associated with NCCP. The impaired motility observed in NCCP patients may play a relevant role in delaying reflux clearing, hence increasing the time of contact between refluxate and esophageal mucosa.

Abstract
BACKGROUND Non-cardiovascular chest pain (NCCP) has a high healthcare cost, but insufficient guidelines exist for its diagnostic investigation. The objective of the present work was to identify important diagnostic indicators and their accuracy for specific and non-specific conditions underlying NCCP. METHODS A systematic review and meta-analysis were performed. In May 2012, six databases were searched. Hand and bibliography searches were also conducted. Studies evaluating a diagnostic test against a reference test in patients with NCCP were included. Exclusion criteria were having <30 patients per group, and evaluating diagnostic tests for acute cardiovascular disease. Diagnostic accuracy is given in likelihood ratios (LR): very good (LR+ >10, LR- <0.1); good (LR + 5 to 10, LR- 0.1 to 0.2); fair (LR + 2 to 5, LR- 0.2 to 0.5); or poor (LR + 1 to 2, LR- 0.5 to 1). Joined meta-analysis of the diagnostic test sensitivity and specificity was performed by applying a hierarchical Bayesian model. RESULTS Out of 6,316 records, 260 were reviewed in full text, and 28 were included: 20 investigating gastroesophageal reflux disorders (GERD), 3 musculoskeletal chest pain, and 5 psychiatric conditions. Study quality was good in 15 studies and moderate in 13. GERD diagnosis was more likely with typical GERD symptoms (LR + 2.70 and 2.75, LR- 0.42 and 0.78) than atypical GERD symptoms (LR + 0.49, LR- 2.71). GERD was also more likely with a positive response to a proton pump inhibitor (PPI) test (LR + 5.48, 7.13, and 8.56; LR- 0.24, 0.25, and 0.28); the posterior mean sensitivity and specificity of six studies were 0.89 (95% credible interval, 0.28 to 1) and 0.88 (95% credible interval, 0.26 to 1), respectively. Panic and anxiety screening scores can identify individuals requiring further testing for anxiety or panic disorders. Clinical findings in musculoskeletal pain either had a fair to moderate LR + and a poor LR- or vice versa. CONCLUSIONS In patients with NCCP, thorough clinical evaluation of the patient's history, symptoms, and clinical findings can indicate the most appropriate diagnostic tests. Treatment response to high-dose PPI treatment provides important information regarding GERD, and should be considered early. Panic and anxiety disorders are often undiagnosed and should be considered in the differential diagnosis of chest pain.

Abstract
The primary role of the esophagus is to propel swallowed food or fluid into the stomach and to prevent or clear gastroesophageal reflux. This function is achieved by an organized pattern that involves a sensory pathway, neural reflexes, and a motor response that includes esophageal tone, peristalsis, and shortening. The motor function of the esophagus is controlled by highly complex voluntary and involuntary mechanisms. There are three different functional areas in the esophagus: the upper esophageal sphincter, the esophageal body, and the LES. This article focused on anatomy and physiology of the esophageal body.

Abstract
Noncardiac chest pain is defined as recurrent chest pain that is indistinguishable from ischemic heart pain after a reasonable workup has excluded a cardiac cause. Noncardiac chest pain is a prevalent disorder resulting in high healthcare utilization and significant work absenteeism. However, despite its chronic nature, noncardiac chest pain has no impact on patients' mortality. The main underlying mechanisms include gastroesophageal reflux, esophageal dysmotility and esophageal hypersensitivity. Gastroesophageal reflux disease is likely the most common cause of noncardiac chest pain. Esophageal dysmotility affects only the minority of noncardiac chest pain patients. Esophageal hypersensitivity may be present in non-GERD-related noncardiac chest pain patients regardless if esophageal dysmotility is present or absent. Psychological co-morbidities such as panic disorder, anxiety, and depression are also common in noncardiac chest pain patients and often modulate patients' perception of disease severity.

Abstract
OBJECTIVE In patients with achalasia, little is known about symptoms of the gastrointestinal tract other than the esophagus. The purpose of this study was to determine the prevalence of two functional disorders, functional dyspepsia (FD) and irritable bowel syndrome (IBS), in a group of treated achalasia patients and to assess the additional impact of these disorders on health-related quality of life (HRQoL). MATERIAL AND METHODS Questionnaires assessing the Rome II criteria for FD and IBS together with the Eckardt clinical symptom score and RAND-36 were sent to 171 treated achalasia patients. RESULTS Of these patients, 76.6% returned their questionnaires. In the group of achalasia patients, 23% fulfilled the criteria for FD (Dutch general population 13-14%), and 21% fulfilled the criteria for IBS (Dutch general population 1-6%). The prevalence of frequent chest pain (at least weekly) was higher in patients with FD and/or IBS than in those without these symptoms (54.2% versus 28.2%; p=0.004). Female patients with achalasia and with frequent chest pain showed a higher probability of fulfilling the FD and/or IBS criteria (adjusted OR 2.90 (1.18-7.14) and 3.35 (1.4-8.1), respectively; both with p <0.05). Patients fulfilling the FD and/or IBS criteria scored a lower HRQoL on the RAND-36 subscales--pain, social functioning, and vitality--as compared with patients not fulfilling these criteria (p <0.006). CONCLUSIONS; Symptoms of FD and IBS in patients with treated achalasia are common and have a negative impact on HRQoL. Therefore, this has to be included in the standard evaluation of achalasia patients. The association with chest pain suggests a mutual underlying mechanism.

Abstract
OBJECTIVES Esophageal disease may mimic acute anginal pain. However, the prevalence of gastroesophageal reflux in the acute setting of patients with clinically unstable angina (UA) pectoris is not known. The aim of this study was to determine the co-existence of coronary artery disease (CAD) and gastroesophageal reflux in UA, and to study the feasibility of esophageal investigation in the chest pain unit. DESIGN 22 patients with clinical UA and confirmed CAD were monitored by continuous vector cardiography and pH-measurement during 24 h of observation. Symptoms of chest pain and episodes of ischemia and reflux were recorded. RESULTS 11 patients (50%) showed abnormal gastroesophageal reflux and another three (14%) had an increased number of reflux episodes. pH-measurements and esophageal manometry were well tolerated. Few chest pain episodes were recorded during the study period, and no association between chest pain, reflux, and ischemia could be shown. CONCLUSION Esophageal reflux is common in patients with UA and established CAD. As reflux-related chest pain may imitate angina pectoris, it is clinically important that gastroesophageal examination in patients with UA seems to be feasible and well tolerated in the 'acute setting'.

The evaluation of gastro-oesophageal reflux and oesophagocardiac reflex in patients with angina-like chest pain following cardiologic investigations. Int J Cardiol 2007; 118:62-8.

Abstract
UNLABELLED The aims of the study were to assess pathogenetic role of gastro-oesophageal reflux and the oesophago-cardiac reflex in subjects with chest pain. To evaluate the prevalence of gastro-oesophageal reflux disease and the oesophago-cardiac reflex in patients with different coronary artery diseases and in coronary spasm. PATIENTS, METHODS Fifty-one patients with chest pain were enrolled after detailed cardiologic evaluation including coronary angiography. The prevalence of gastrooesophageal reflux disease was established by symptom analysis, upper gastrointestinal endoscopy, 24-h oesophageal pH monitoring, and oesophageal manometry. The oesophago-cardiac reflex was established by oesophageal acid perfusion test (0.1 N HCl and 0.9% NaCl, 120-120 ml/10 min in a blinded manner) combined with transoesophageal Doppler echocardiographic coronary flow measurement in the left anterior descending artery. RESULTS Gastro-oesophageal reflux disease was established in 45% (23/51) of the patients. Oesophageal acid perfusion decreased the coronary flow velocity in 49% (25/51) of the patients indicating the presence of oesophago-cardiac reflex. Oesophago-cardiac reflex was present more frequently in patients with coronary spasm, than in patients with either epicardial coronary artery disease or microvascular coronary disease (p<0.02). Patients with oesophago-cardiac reflex had higher DeMeester scores, increased number of reflux episodes, fraction time below pH 4, and prolonged acid reflux episodes (p<0.05 for each parameter). CONCLUSIONS Gastro-oesophageal reflux disease is frequently established in patients with either epicardial or microvascular coronary artery disease or with coronary spasm. The oesophago-cardiac reflex was more frequently observed in patients with coronary spasm. The combination of oesophageal acid perfusion test and transoesophageal Doppler echocardiographic coronary flow measurement seems to be a useful method for the detection of this reflex. Patients with prolonged gastro-oesophageal acid reflux episodes, erosive oesophagitis and coronary spasm may be at higher risk for the development of linked-angina.

Abstract
Chest pain is common in medical consultations. One of the most frequent and serious causes is acute ischemic heart disease, which must be ruled out. The gold standard is coronary angiography. Noncardiac recurrent chest pain has a favorable prognosis. The most frequent cause is esophageal disease, with a prevalence of between 20% and 50%. The most frequent form is gastroesophageal reflux disease followed by esophageal motor disorders. Empirical treatment with high-dose proton pump inhibitors should be considered as a diagnostic-therapeutic test before performing exhaustive complementary investigations of esophageal function. Among complementary tests, manometry combined with 24-hour pH-metry has the highest diagnostic yield. Antidepressants are an acceptable therapeutic option in patients with esophageal visceral hyperalgesia.

Abstract
The close anatomical relations of the heart and oesophagus, and the similarity of symptoms attributable to disorders of either organ, often lead to diagnostic difficulty in patients with chest pain. A definitive diagnosis of non-cardiac chest pain attributable to oesophageal reflux or spasm is hampered, both by the need for prolonged ambulatory monitoring of pH, manometry, and endoscopy, and by the common occurrence of asymptomatic reflux and spasm, and the corresponding difficulty in linking an episode of reflux or spasm with an episode of pain. Moreover, some patients with non-cardiac chest pain and normal tests of oesophageal structure and function have centrally mediated hypersensitivity, both within and without the oesophagus. Rather than proceed with investigations, in the absence of symptoms to suggest structural disease of the oesophagus, it would be reasonable to attempt symptomatic treatment with a proton pump inhibitor or an antidepressant.

Abstract
Chest pain is common: one in four of the population have an episode annually. Of those who present to hospital, nearly two-thirds have noncardiac chest pain. More than half of these cases might have gastroesophageal reflux disease. Opinion differs over what is the most appropriate application of current investigatory methods. Evidence suggests that, once cardiac disease is ruled unlikely, empiric use of a proton pump inhibitor is an option; if acid suppression fails, detailed investigations as clinically indicated can be considered. A range of esophageal investigations is available, including 24-hour or 48-hour esophageal pH testing and esophageal manometry, as well as provocative tests, but there is no consensus as to which methods are the most useful. Psychiatric evaluation is not routine, but psychiatric or psychological disorders are common. Musculoskeletal disorders are also common, but are frequently overlooked. It is possible to subject patients to a comprehensive set of investigations before empiric therapy, but recent studies have failed to demonstrate an improved outcome using this exhaustive approach. A new tactic is required, with less attention spent on absolute diagnostic accuracy and more emphasis on optimizing the long-term clinical outcome in patients with noncardiac chest pain. It is possible that the targeted use of multiple drug trials in a policy of 'therapy as investigation' might be a superior methodology.

Abstract
Functional chest pain is a common, yet poorly understood entity. The focus of this review is to explore the evolving research and clinical approaches with a particular emphasis on the sensory or afferent neuronal dysfunction of the esophagus as a key player in the manifestation of this pain syndrome. Although once regarded as a psychologic or esophageal motility disorder, recent advances have shown that many of these patients have visceral hyperalgesia. Whether visceral hypersensitivity is a central or peripheral perturbation of the gut-brain axis remains debatable. Response to empirical therapy with high-dose proton pump inhibitors, upper endoscopy, or prolonged recording of esophageal pH may identify gastroesophageal reflux disease as a source of chest pain. Esophageal balloon distension study can serve as a useful test for identifying hypersensitivity. Newer techniques, including functional magnetic resonance imaging, magnetoencephalogram, and cortical evoked potentials, are being investigated. High doses of proton pump inhibitors and low doses of tricyclic antidepressants or trazadone remain the mainstay of therapy, although several new approaches including theophylline have been shown to be beneficial.

Abstract
Gastroesophageal reflux disease (GERD) is linked to several extraesophageal disease states including laryngitis, asthma, chronic cough, and noncardiac chest pain (NCCP). Although 24-hour pH monitoring is considered the "gold standard" in the diagnosis of typical GERD, it is also increasingly used in establishing the diagnosis of GERD in patients with extraesophageal symptoms. The clinical utility of pH monitoring in this patient population, however, remains controversial. In this article, the authors examine the role of pH monitoring in laryngitis, asthma, chronic cough, and NCCP.

Abstract
Catheter based high frequency intraluminal ultrasound (HFIUS) imaging is a powerful tool to study esophageal sensory and motor function and dysfunction in vivo in humans. It has provided a number of important insights into the longitudinal muscle function of the esophagus. Based on the ultrasound images and intraluminal pressure recordings, it is clear that there is synchrony in the timing as well as the amplitude of contraction between the circular and the longitudinal muscle layers of the esophagus in normal subjects. On the other hand, in patients with spastic disorders of the esophagus, there is an asynchrony of contraction related to the timing and amplitude of contraction of the two muscle layers during peristalsis. Achalasia, diffuse esophageal spasm, and nutcracker esophagus (spastic motor disorders of the esophagus) are associated with hypertrophy of the circular as well as longitudinal muscle layers. A sustained contraction of the longitudinal muscle of the esophagus is temporally related to chest pain and heartburn and may very well be the cause of symptoms. Longitudinal muscle function of the esophagus can be studied in vivo in humans using dynamic ultrasound imaging. Longitudinal muscle dysfunction appears to be important in the motor and sensory disorders of the esophagus.

Abstract
Catheter-based high-frequency intraluminal ultrasound imaging is a powerful tool to study esophageal sensory and motor function and dysfunction in vivo in humans. It can be combined with manometry, pH, and impedance measurement techniques to determine the relationships between different physiologic parameters. High-frequency intraluminal ultrasound imaging has provided a number of important insights regarding the longitudinal muscle function of the esophagus. On the basis of the ultrasound images and intraluminal pressure recordings, it seems that there is synchrony in the timing and the amplitude of contraction between the circular and longitudinal muscle layers. A sustained contraction of the longitudinal muscle layer is temporally related to esophageal chest pain and heartburn. The biomechanics of the esophageal wall and its relationship to sensory and motor function can be studied in humans in vivo by using high-frequency intraluminal ultrasound much more precisely than has previously been possible. Achalasia, diffuse esophageal spasm, and nutcracker esophagus are associated with hypertrophy of circular and longitudinal muscle layers. Finally, high-frequency intraluminal ultrasound imaging is the only technique that can detect reflux-related distention of the esophagus and its role in esophageal symptoms. Future approaches to display and quantify ultrasound image data are discussed. The principles of high-frequency intraluminal ultrasound described here are also applicable to study of the motor and sensory function of the other regions of the gastrointestinal tract.

Abstract
Extraesophageal manifestations of gastroesophageal reflux disease (GERD) are essentially complications of GERD that primarily involve organs that are in proximity to the esophagus. Non-cardiac chest pain (NCCP) is an atypical manifestation of GERD, because symptoms originate in essence from the esophagus. In both atypical and extraesophageal manifestation of GERD frequent heartburn is uncommon and lack of GERD symptoms is not unusual. Esophageal mucosal injury is rarely present making upper endoscopy a low-yield procedure in both conditions. While association with GERD has been commonly reported, the extent of causality remains unknown. In NCCP, the usefulness of the proton pump inhibitor (PPI) test in diagnosing GERD-related NCCP has been established. Similar value in extraesophageal manifestations of GERD has been proposed, but rarely studied. While treatment of extraesophageal manifestations of GERD remains a challenge, PPIs in at least double the standard dose, should be considered for the initial therapy. Properly designed therapeutic studies are still lacking as well as the exact role of antireflux surgery in this patient population.

Abstract
OBJECTIVE To describe diurnal variations of esophageal motor function in children using combined ambulatory 24-hour esophageal manometry and continuous intraluminal pH measurement (MP24). METHODS Medical records of all patients referred for the performance of MP24 from 1995 to 2002 at a tertiary care center were reviewed. Patients were selected retrospectively for this study using the following inclusion criteria: (1) no dysphagia, (2) normal upper gastrointestinal barium radiograph, (3) normal esophagogastroduodenoscopy and biopsies, (4) normal stationary esophageal manometry, (5) normal esophageal pH probe, and (6) no gastrointestinal pathology appearing after long-term follow-up. Data from the MP24 of these children were retrospectively analyzed for differences between meal, upright, and supine periods using nonparametric univariate analysis. RESULTS One hundred twenty-three children had MP24 during the study period. Eleven met the criteria for normality and were included. Their mean age was 12.4 +/- 1.5 years. The number of contractions/minute in the upper, middle, and lower esophageal body differed significantly during meals and in the upright and supine periods (P < 0.01). A significant increase in motor activity occurred during meals (P < 0.01). There was less motor activity observed in the supine position than in the upright position (P < 0.01). There were significant differences in effective (P < 0.05) and total propagated peristalsis among the meal, upright, and supine periods (P < 0.01), with the largest percentage of propagated contractions observed during meals. CONCLUSION This study provides the first information on prolonged esophageal motor activity in pediatric patients without esophageal disease. MP24 in children demonstrates significant diurnal variations in esophageal motor function that is similar to the findings in studies of healthy adults.

Abstract
Manifestations of atypical gastroesophageal reflux disease (GORD) are varied, and the presentation of atypical symptoms may occur in the absence of typical symptoms. The most sensitive and specific investigation for GORD is pH monitoring, and its application in atypical disease is utilized throughout this paper as a basis for correlating disease and pathogenesis. The less well-known areas of laryngeal manifestations, particularly chronic hoarseness and globus, are discussed in addition to recent work on orodental manifestations. Well-known areas of cardiac and respiratory manifestations, which include chronic cough and asthma, are also reviewed. Evidence from clinical trials indicates that aggressive anti-reflux therapy in patients with atypical symptoms can be effective. Where appropriate, medical therapy may involve long-term proton pump inhibitor, although further research outlining the roles of other therapies such as surgery is awaited.

Abstract
Noncardiac chest pain is a heterogeneous condition for which diagnosis and treatment are challenging. Research is needed to streamline evaluation to minimize unnecessary invasive testing and costs. Chest pain clinics to assess chest pain patients are popular in the United States and may be of value in reassuring patients and reducing presentation to hospital; however, recently this has been contended [111]. Options for the effective treatment of NCCP are dependent on the risk of an adverse outcome and the cost-effectiveness of the management algorithm that is followed. Most (64%) of those presenting to the emergency department with chest pain are classified as having NCCP [112,113]. GERD is probably the most important cause and application of a test of acid suppression with a high-dose PPI for 1 to 2 weeks seems to be a useful diagnostic tool. In those patients with GERD-related NCCP, short-term and potentially long-term therapy with a PPI (commonly higher than standard dose) is required to alleviate symptoms. Esophageal dysmotility is relatively uncommon in patients with NCCP and evaluation by esophageal manometry might be limited to rule out achalasia. Chest wall syndromes are common but probably often missed. Many patients with NCCP have psychologic or psychiatric abnormalities, as either the cause or an effect of the chest pain, but diagnosis here depends on techniques not applied easily in the acute situation. Pain modulators seem to offer significant improvement in chest pain symptoms for non-GERD-related NCCP. Finally, trials of management strategies to deal with this problem are required urgently, because the earlier discharge of patients with NCCP may exacerbate the problem. Fig. 2 provides a flow chart for diagnosis and treatment of NCCP.

Abstract
UNLABELLED Noncardiac chest pain (NCCP) presents as a frequent diagnostic challenge, with patients tending to use a disproportionate level of health care resources. Gastroesophageal reflux disease (GERD) is the most frequent cause of NCCP. GOALS To test the efficacy of a potent acid-suppressing agent as a diagnostic test in the evaluation of NCCP and to compare it with three commonly used tests. STUDY Eighteen men and 24 women, aged 22 to 77 years, who presented with recurrent chest pain complaints of a noncardiac etiology, as determined by rest/stress perfusion imaging with technetium Tc99m sestamibi (MIBI), were enrolled in a prospective, double-blinded, placebo-controlled, crossover trial using high-dose omeprazole. Thirty-seven patients completed both arms of the trial. Findings were compared with those of endoscopy, manometry, and ambulatory 24-hour two-channel esophageal pH monitoring. All patients underwent initial diagnostic upper endoscopy, esophageal manometry, and 24-hour pH monitoring. Patients were then randomly assigned to either placebo or omeprazole (40 mg/d orally twice daily) for 14 days, washed out for 21 days, and then crossed over. Patient's symptoms were determined using a Visual Analogue Scale to measure the severity of chest pain before and after each period. RESULTS Seventy-one percent of patients in the omeprazole arm reported improved chest pain, whereas only 18% in the placebo arm did. Abnormal results on manometry (20%), 24-hour pH monitoring (42%), or endoscopy with visual evidence of esophagitis (26%) were found less frequently. Combination of the three tests did not significantly increase their usefulness. In NCCP patients with GERD, as defined by positive results on a 24-hour pH test or presence of esophagitis on endoscopy, omeprazole treatment led to a response in 95% of patients, whereas 90% of GERD-positive patients treated with placebo did not respond. Of NCCP patients determined to be GERD negative, 39% responded to omeprazole. CONCLUSIONS Omeprazole as a first diagnostic tool in the evaluation of MIBI-negative NCCP is sensitive and specific for determining the cause of NCCP. Endoscopy, manometry, and 24-hour pH monitoring were not only less sensitive in diagnosing NCCP, but they were significantly more expensive.

Abstract
BACKGROUND Laparoscopic fundoplication cures heartburn and regurgitation in patients with gastroesophageal reflux disease (GERD) but its effect on the chest pain that is also experienced by some patients is less clear. Confusion stems from the fact that it is difficult to determine preoperatively whether the chest pain is actually caused by the reflux. Therefore, we designed a study in patients with GERD and chest pain that would assess the value of pH monitoring in establishing a correlation between the symptom and the disease, the predictive value of pH monitoring on the results of surgical treatment, and the outcome of laparoscopic fundoplication on chest pain in patients with GERD. METHODS Of 487 patients who underwent laparoscopic fundoplication for GERD at our institution between October 1992 and July 2000, 165 (34%) complained of chest pain in addition to heartburn and regurgitation. Their symptoms had been present for an average of 118 months. The pH monitoring tracings were analyzed for a correlation between episodes of reflux and chest pain. The mean length of follow-up was 13 months. RESULTS Among the 165 patients with chest pain, the relationship between pain and reflux during pH monitoring was as follows: 39 patients (group A) experienced no chest pain during the study; in 28 patients (group B), chest pain correlated with reflux in <40% of instances; in 98 patients (group C), chest pain correlated with reflux in ?40% of instances. Chest pain improved postoperatively in 65% of group A patients, 79% of group B patients, and 96% of group C patients (group C vs A and B: p <0.05). Heartburn and regurgitation resolved or improved in 97% and 95% of patients, respectively. CONCLUSIONS These data show that pH monitoring helped to identify a relationship between chest pain and reflux; and when the two coincided, the chest pain was relieved by antireflux surgery.

Abstract
AIMS To test the usefulness of upper gastrointestinal investigations and quality of life assessment in Chinese patients with non-cardiac chest pain. METHODS Seventy-eight consecutive patients with non-cardiac chest pain underwent upper endoscopy. Eight patients had upper gastrointestinal pathology (10%). The remaining 70 patients received acid perfusion test, oesophageal manometry and 24-h ambulatory oesophageal pH (n=65)/manometry (n=61), and the results were compared with those of healthy controls (n=20). Symptoms and quality of life (SF-36) were assessed by standard validated questionnaire. RESULTS Significant acid reflux symptoms were present in five (5/70, 7%) patients. Abnormal 24-h oesophageal pH, indicating gastro-oesophageal reflux, was found in 19 (19/65, 29%) patients. The percentage of simultaneous contractions was higher and the percentage peristalsis was lower in patients with non-cardiac chest pain when compared with normal subjects by 24-h ambulatory manometry. Patients with non-cardiac chest pain had a lower SF-36 score when compared to controls. CONCLUSIONS Typical acid reflux symptoms are uncommon in Chinese patients with non-cardiac chest pain, but abnormal 24-h pH results, indicating gastro-oesophageal reflux, were found in 29% of patients. Ineffective contractions were more frequently found in patients with non-cardiac chest pain by 24-h ambulatory manometry, which may have a bearing on the impaired quality of life in such patients. Upper gastrointestinal investigations are useful for the evaluation of Chinese patients with non-cardiac chest pain.

Abstract
Approximately 30% of coronary angiograms performed in this country are negative for significant coronary artery disease. These patients are classified as having noncardiac or unexplained chest pain (UCP). Despite the good overall prognosis, this condition has significant morbidity and costs. The pathophysiology of this condition is likely caused by overlapping cardiac, esophageal, and psychiatric abnormalities with visceral hyperalgesia playing a central role. Gastroenterologists are often consulted in the evaluation of these patients because esophageal disorders are among the most common conditions associated with UCP. However, clinical symptoms are unreliable in differentiating between esophageal and cardiac causes of UCP. Gastroesophageal reflux disease, not esophageal motility disorders, is the most common esophageal disorder present in patients with UCP. The most useful diagnostic test in the evaluation of UCP is 24-h pH monitoring. An initial empiric trial of high-dose acid suppression is the most cost-effective intervention in the management of these patients. A clinical algorithm is suggested for the evaluation and treatment of UCP.

Abstract
There are numerous tests for which a diagnostic value in the context of gastro-oesophageal reflux disease has been claimed. Some of these tests (e.g. the acid perfusion test) have become obsolete after the advent of 24-hour oesophageal pH monitoring. With the latter test not only can excessive reflux be identified, but also, and more importantly, a temporal relationship can be demonstrated between a patient's symptoms and reflux episodes. Radiographical examination of the oesophagus has largely been replaced by endoscopy, although the use of the former test is still indicated in certain circumstances (e.g. in the differentiation of sliding from para-oesophageal hiatus hernia). In clinical practice, the so-called proton pump inhibitor test has gained considerable popularity. Despite several studies on the specificity and sensitivity of this test, its value has not yet been established with sufficient accuracy. Conventional manometric evaluation of lower oesophageal sphincter pressure has been over-emphasized as a diagnostic test in gastro-oesophageal reflux disease.

Abstract
PURPOSE Recent evidence suggests that an empiric trial of omeprazole (the "omeprazole test") is sensitive and specific for diagnosing gastroesophageal reflux disease (GERD) as the cause of noncardiac chest pain. Our objective was to examine the clinical, economic, and policy implications of alternative diagnostic strategies for patients with noncardiac chest pain. METHODS Decision analysis was used to evaluate the clinical and economic outcomes of two diagnostic strategies that begin with the omeprazole test (60 mg daily for 7 days) followed sequentially by invasive testing utilizing endoscopy, ambulatory 24-hour esophageal pH monitoring, and esophageal manometry as necessary, compared with two traditional strategies involving sequential invasive diagnostic tests. Cost estimates were based on Medicare reimbursement and the Red Book of average wholesale drug prices. Probability estimates were derived from a systematic review of the medical literature. RESULTS The average cost per patient for the four diagnostic strategies varied from $1,859 to $2,313. Strategies utilizing the initial omeprazole test resulted in 84% of patients being symptom free at 1 year, compared with 73% to 74% for the strategies that began with invasive tests. The strategy of the omeprazole test, followed if necessary by ambulatory pH monitoring, then manometry, and then endoscopy, was both most effective and least expensive. It led to an 11% improvement in diagnostic accuracy and a 43% reduction in the use of invasive diagnostic tests, thus yielding an average cost savings of $454 per patient, compared with the strategy of beginning with endoscopy, then pH monitoring, and then manometry. CONCLUSIONS Among patients with noncardiac chest pain, diagnostic strategies that begin with the omeprazole test result in reduced costs, improved diagnostic certainty, and a greater proportion of symptom-free patients at 1 year than do traditional strategies that begin with invasive diagnostic tests.

Abstract
A substantial proportion of patients with chest pain referred to hospital, show signs of coronary artery disease. Anginal pain could be conceptualized as a warning signal for coronary artery disease and impending death. But, for many reasons this theory is partly disputed. Firstly, not all ischemic episodes are accompanied by anginal pain (silent ischemia). Secondly, chest pain indistinguishable from true angina pectoris may be the result of other abnormalities of thoracic viscera. Nevertheless acute severe cardiac ischemia often gives rise to anginal chest pain. Unstable angina pectoris is carrying a higher risk for future events in spite of intensive medical treatment. A special problem are patients awaiting coronary intervention because of severe ischemia and maximum medical treatment, who experience ischemic pain. New treatment regimens are needed for these patients. This review discusses the symptom of visceral pain from the heart, angina pectoris, its relation to ischemia and unstable angina pectoris. It also addresses the role of afferent nerve stimulation (transcutaneous electrical nerve stimulation, TENS) in the treatment of severe angina pectoris as well as recent findings of TENS applicability in unstable angina.

Abstract
BACKGROUND & AIMS Intraluminal pressure recording systems have not demonstrated predictable esophageal motor correlates of unexplained chest pain. This study used continuous high-frequency intraluminal ultrasonography to characterize esophageal contraction at the time of spontaneous and provoked chest pain. METHODS Intraluminal pressure, pH, and ultrasound images of the esophagus were recorded for a maximum of 24 hours in 10 subjects with unexplained chest pain. Changes in esophageal muscle thickness were measured as a marker of muscle contraction. Ten additional subjects with suspected esophageal chest pain were studied after edrophonium chloride injection to provoke symptoms. Ten healthy subjects were studied as controls. RESULTS Eighteen of 24 spontaneous chest pain episodes were preceded by a sustained esophageal contraction (SEC) detected on ultrasonography (mean duration, 68.0 seconds). This motor pattern was not accompanied by changes in intraluminal pressure. Four of 24 asymptomatic control periods were accompanied by SEC, although these contractions were of shorter mean duration (29.0 seconds; P < 0.001). SEC was observed in 5 subjects with a positive chest pain response to edrophonium and in none of the 5 subjects with a negative response. SEC was not detected in normal subjects. CONCLUSIONS There is a strong temporal correlation between a previously unrecognized esophageal motor event, SEC, and both spontaneous and provoked esophageal chest pain.

Abstract
Functional gut disorders include several clinical entities defined on the basis of symptom patterns (e.g., functional dyspepsia, irritable bowel syndrome, functional abdominal pain, functional abdominal bloating), for which there is no established pathophysiological mechanism. Because there is no well-defined pathophysiological target, treatment should be aimed at symptom improvement. Prokinetics and antispasmodics have been widely used in the treatment of functional gut disorders on the assumption that disordered motility is the underlying cause of symptoms, and symptom improvement is indeed achievable with these compounds in some, but not all, patients with features of hypo- or hypermotility, respectively. In the first part of this review, we cover the basic pharmacology and discuss the rationale for the clinical use of prokinetics and antispasmodics. On the other hand, in the past few years, the explosive growth in the research focusing on visceral sensitivity and visceral reflexes has suggested that at least some patients with functional gut disorders have altered visceral perception. Thus, the second part of the review covers these developments and focuses on studies addressing the issue of drugs modulating visceral sensitivity.

Abstract
The use of radionuclide transit (RT) as a screening test for chest pain of oesophageal origin has been debated. The aim of this study was to determine the value of RT as a screening test for oesophageal disorders in comparison with oesophageal manometry in patients admitted with acute chest pain but without acute myocardial infarction (non-AMI patients), and to assess the frequency of oesophageal disease present in these patients. A total of 222 non-AMI patients entered the study. An extensive examination programme comprised noninvasive cardiac studies, pulmonary studies, a careful physical examination of the musculoskeletal system, and oesophago-gastric examinations including endoscopy, pH monitoring of the oesophagus and a Bernstein test. In 91% of the patients one or more diagnoses were obtained. Based on clinical and laboratory data a 'consensus' diagnosis was made. With manometry as the reference RT had a poor sensitivity (35%) but an acceptable specificity (82%). With the consensus diagnosis as the gold standard the sensitivities of both manometry and RT were poor (29%), whereas the specificity of RT, but not of manometry, was very high (97%). Gastrointestinal diagnoses were found in 57% of the patients. In conclusion, none of the applied oesophageal examinations are valuable as single screening tests. Both RT and manometry have low sensitivities. RT may be used as a cheap, noninvasive and rapid supplementary examination. When positive, it strongly supports further invasive studies of the oesophagus in non-AMI patients with unexplained chest pain.

Abstract
The diagnosis of early myocardial infarction, especially in association with atypical clinical presentations, can be difficult to establish. Continued observation of high-risk patients, with multiple serial electrocardiographs and the use of other diagnostic modalities as available, is essential to prevent the inadvertent premature discharge of patients with evolving myocardial infarcts from the accident and emergency department.

Abstract
OBJECTIVES We wanted to supply a new 'vertical' approach in the analysis of oesophageal contraction data by describing variables of oesophageal function in relation to the amplitude of contraction. METHODS Twenty-four-hour oesophageal manometry was performed in 20 healthy volunteers (11 women and 9 men; mean age, 47.5 years). Computer analysis was performed in pressure windows at 10, 15, 20, 30, 40, 50, 60, 70, and 80 mm Hg. Within each window two variables were extracted: the distribution (%) of peristaltic contractions and median duration (sec) of contractions. RESULTS The percentage of peristaltic contractions increased with increasing amplitude of contractions during the upright position (15-20 mm Hg window: mean (+/- SD) 68.2% (+/- 13.3%), versus 70-80 mm Hg window: 85.0% (+/- 13.0%) (P < 0.001)) and meal periods (66.9% (+/- 13.8%) versus 92.2% (+/- 11.2%) (P < 0.001)) but not in the supine position (75.9% (+/- 14.6%) versus 73.5% (+/- 16.1%) (P = 0.64)). Contraction duration diminished with increasing contraction amplitude (upright, 15-20 mm Hg window: 3.2 sec (+/- 1.5 sec) versus 70-80 mm Hg window: 1.5 sec (+/- 1.0 sec) ( P < 0.0001); meal: 3.8 sec (+/- 1.7 sec) versus 1.9 sec (+/- 1.1 sec) (P < 0.01); supine: 4.1 sec (+/- 3.0 sec) versus 2.2 (+/- 1.5 sec) (P = 0.03)). The percentage of peristaltic contraction was lower during the supine periods than during meals and upright periods at high amplitudes (70-80 mm Hg window; P < 0.05). The number of contractions decreased linearly on a logarithmic scale with pressure window amplitude. CONCLUSIONS Pressure wave amplitude and organization were closely related. Accurate base-line determination and delineation are critical for the interpretation of oesophageal manometric recordings.

Abstract
STUDY OBJECTIVE The prevalence of esophageal disorders (dysmotility and/or gastroesophageal reflux) in patients with chest pain newly referred to a cardiologic clinic is unknown. The aims of our study were to investigate the prevalence of esophageal abnormalities in these patients and to assess the value of medical history in predicting the origin of the patient's chest pain. DESIGN We evaluated 28 consecutive patients who were newly referred to the cardiologist because of angina-like chest pain. Patients with evidence of severe myocardial ischemia were excluded. Cardiologic evaluation included medical history, physical examination, ECG, and exercise testing; further cardiologic workup was carried out only when considered necessary. Gastroenterologic evaluation consisted of medical history, esophageal manometry, endoscopy, and 24-h ambulatory monitoring of esophageal pH and pressure. MEASUREMENTS AND RESULTS In five patients a diagnosis of ischemic coronary artery disease was made. In only two of these five patients, the cardiologic history strongly suggested a cardiac origin of the pain. Twelve patients had a pathologic 24-h pH profile, four of whom also had reflux esophagitis. Ten patients had symptomatic reflux. In only three of these ten patients, the history was judged to be indicative of an esophageal origin of the chest pain. No motility disorders were found. CONCLUSIONS Thirty-six percent of the patients with chest pain newly referred to a cardiologic out-patient clinic have symptomatic gastroesophageal reflux. Neither cardiologic nor gastroenterologic history data have a high predictive value with respect to the origin of the chest pain.

Abstract
This article has summarized the epidemiology of several disorders commonly seen in a gastroenterologist's practice. The emphasis has been on population-based data because many people with these disorders never seek health care, and psychological features have been shown to be strongly associated with health care-seeking behavior. Each of these disorders is common in the community; in fact, the majority of the population experiences intermittent gastrointestinal symptoms. In general, the national surveys sponsored by the U.S. Public Health Service have been shown to underestimate the prevalence of these conditions. In part, this is due to the fact that subjects are asked to report diagnoses rather than symptoms, and current coding schemes do not provide specific codes for each of the functional gastrointestinal disorders. Still, these studies have demonstrated the large number of physician visits and overall costs attributable to these disorders. A number of surveys of more limited populations have been done to assess the prevalence of these disorders. Rates have varied because of the definitions used and the degree to which organic diagnoses are excluded. These studies have been helpful in demonstrating the burden of illness in the community. Age and gender differences in the community have been much less marked than those identified in clinic-based studies, thus highlighting the importance of population-based research. Future studies need to focus on the incidence and natural history of these disorders. Studies of incidence cases can best evaluate the role of etiologic factors, whereas studies of prevalent cases are best for assessing the burden of disease in the community. Understanding the natural history of these disorders is important in determining the efficacy of future therapeutic interventions. The fact that these disorders represent 50% of visits to a gastroenterologist practice highlights the importance of these disorders and the potential contribution of gastrointestinal dysmotility in clinical practice.

Abstract
Ambulatory esophageal manometry/pH-metry has been used primarily in patients with chest pain of presumed esophageal origin, and it is unclear whether the discriminating power of this test applies to other esophageal symptoms. In the present study, prolonged ambulatory manometry/pH recordings were compared in 17 healthy controls, 12 patients with atypical chest pain, and 11 patients with chest pain and nonstructural dysphagia using the Synectics microdigitrapper system. Chest pain patients tended to have higher values for all the pH variables, but their esophageal motility parameters were no different than controls. On the other hand, the chest pain plus dysphagia group was characterized by a significantly lower proportion of propagated contractions between 10 and 5 cm above the lower esophageal sphincter. This group also tended to have a higher frequency of high-amplitude or prolonged-duration contractions. In comparison to the results of standard stationary esophageal manometry, the prolonged ambulatory recordings were more sensitive in detecting esophageal motor dysfunction in the two patient groups. This study suggests that quantitative analysis of ambulatory pH/motility recordings is a sensitive method of evaluating patients with suspected esophageal dysfunction.

Abstract
BACKGROUND The aim of this study was to determine which motility data of patients with noncardiac chest pain (NCCP) differ from those of controls on the basis of long-term manometry and to evaluate the coexistence of motility disorders and pathologic acid reflux. Further, motility disorders were tested as to whether they were secondary to acid reflux. METHODS Combined long-term pH/manometry was performed in 95 patients with NCCP, using one pH-electrode and two pressure transducers. The motility data were compared with those of healthy controls (n = 40). In addition, an intraindividual patient-oriented motility analysis was performed. Evaluated were the amplitude, the duration in the distal and proximal esophagus, and the type of propagation, propulsive and simultaneous, of esophageal contractions. Ten patients with pathologic acid reflux and hypermotility disorders received 20 mg omeprazole twice daily and were investigated again 4 weeks after therapy began. RESULTS The median distal pressure amplitude (39.4 versus 28.9 mmHg, p < 0.0001) and the median percentage of simultaneous contractions (18.5% versus 10%; p < 0.0001) were significantly higher in patients with NCCP than in controls. In addition, patients whose symptoms correlated with abnormal motility (n = 18) had a significantly higher median duration of contractions (3.8 sec versus 3.2 sec; p < 0.03) than controls Patients with pathologic acid reflux showed a higher median distal pressure amplitude (38.3 mmHg versus 28.9 mmHg; p < 0.0001) and median percentage of simultaneous contractions (18% versus 10%; p < 0.0001) than controls. Furthermore, a high rate of coexistence with hypermotility disorders was observed (64%). These disorders persisted after acid suppression therapy. CONCLUSIONS Patients with NCCP differ from controls in their esophageal motility. Simultaneous contractions of increased amplitude and duration are pathologic. The intraindividual patient-oriented motility analysis is an appropriate evaluation method. Hypermotility disorders occur often in patients with pathologic acid reflux, but apparently they are not dependent on it.

Abstract
OBJECTIVES To investigate the association between exertional chest pain and gastroesophageal reflux in patients with normal coronary angiograms and in controls by measuring oesophageal pH during treadmill exercise tests and to compare the results with routine ambulatory monitoring. DESIGN Case control study. SETTING Tertiary referral cardiac unit. PATIENTS 50 consecutive patients with chest pain and completely normal coronary angiograms and 16 controls with coronary artery stenoses. MAIN OUTCOME MEASURES Episodes of acid reflux and chest pain during treadmill exercise; a symptom index expressing the percentage of episodes of pain related to acid reflux during ambulatory monitoring. RESULTS Four (8%) patients and two (12%) controls had reflux during treadmill exercise (NS). 32 (64%) and 16 (100%) reported chest pain, but only three (6%) and two (12%) had coincident reflux (NS). Reflux was as frequent before, during, and after treadmill exercise (five (8%) v six (9%) v two (3%)) in the 66 subjects; (NS). 19 (38%) patients and three (19%) controls had abnormal reflux on ambulatory monitoring (NS). Eight (16%) and three (19%) had a symptom index > 50%, but six and two of these reported pain without coincident reflux during treadmill exercise. CONCLUSION There are many potential causes of chest pain in patients with angiographically normal coronary arteries. Although gastroesophageal reflux is commonly implicated and many patients have a high incidence of spontaneous reflux during ambulatory monitoring, it rarely occurs during exertion and the association with chest pain is poor.
