The evaluation of gastro-oesophageal reflux and oesophagocardiac reflex in patients with angina-like chest pain following cardiologic investigations

Exploring Roemheld syndrome: a comprehensive review with proposed diagnostic criteria

Roemheld syndrome (RS) is a condition that triggers cardiac symptoms due to gastrointestinal compression of the heart. It is often misdiagnosed as other types of cardiac or digestive disorders, leading to unnecessary treatments and reduced quality of life. Here, we provide a thorough review of RS, covering its pathogenesis, etiology, diagnosis, treatment, and outcome. We found that a number of conditions, including gallstones, hiatal hernia, excessive gas, and gastroesophageal reflux syndrome, can cause RS. The symptoms of RS can include chest pain, palpitations, shortness of breath, nausea, vomiting, bloating, and abdominal pain. Clinical history, physical examination, electrocardiograms, and improvement in symptoms following gastrointestinal therapy can all be used to identify RS. We also propose a set of criteria, the IKMAIR criteria, to improve the diagnostic approach for this condition. Dietary changes, lifestyle adjustments, pharmaceutical therapies, and surgical procedures can all be used to control RS. Depending on the underlying etiology and the outcome of treatment, RS has a varying prognosis. We conclude that RS is a complicated and understudied disorder that needs more attention from researchers and patients as well as from medical professionals. We recommend the inclusion of RS in the differential diagnosis for individuals with gastrointestinal problems and unexplained cardiac symptoms. Additionally, we advise treating RS holistically by attending to its cardiac and gastrointestinal components.

Gastroesophageal Reflux Disease and Idiopathic Lung Fibrosis. From Heartburn to Lung Transplant, and Beyond

Idiopathic pulmonary fibrosis (IPF) and gastroesophageal reflux disease (GERD) are undoubtedly related. Even though it is not clear yet which one is the primary disease, they certainly interact increasing each other's severity. Symptoms are unreliable to diagnose GERD in patients with IPF, and objective evaluation with pH monitoring and/or bronchoalveolar lavage analysis is mandatory. Pharmacological treatment with proton pump inhibitors (PPIs) may bring control of IPF in few patients, but PPIs do not control reflux but just change the pH of the gastric refluxate. Surgical therapy based on a fundoplication is safe and effective as it controls any type of reflux, independently from the pH of the gastric refluxate. In patients waiting for lung transplantation (if they can tolerate a laparoscopic operation under general anesthesia), a fundoplication before the operation might block the progression of IPF, while after transplantation it might prevent rejection by preventing the bronchiolitis obliterans syndrome.

The interplay between gastrointestinal and cardiovascular diseases: a narrative review focusing on the clinical perspective

Both cardiovascular and gastrointestinal disorders represent considerable health burden on community clinics and hospitals with overwhelming economic cost. An overlap in the occurrence of these disorders is encountered in daily practice. Both affect each other in bidirectional manner through several mechanisms including altered hemodynamics, systemic inflammation, bacterial overgrowth and interactions and adverse effects of medications. In addition, to the known overlap in the symptoms occurrence of upper gastrointestinal tract diseases and cardiovascular diseases (CVDs). Awareness of this interplay and its clinical manifestations optimizes patient management, and could prevent catastrophic consequences and even save lives. In this review, we highlighted the clinical aspects of this bidirectional association between gastrointestinal and CVDs aiming to shed light on this topic and improve patients' care.

Improved control of hypertension following laparoscopic fundoplication for gastroesophageal reflux disease

This study aims to determine whether successful laparoscopic fundoplication for gastroesophageal reflux disease (GERD) can improve the control of hypertension. We conducted an observational study of GERD patients with hypertension. The esophageal and gastroesophageal symptoms of these patients were successfully treated with laparoscopic fundoplication, as measured by the reduced GERD symptoms and proton pump inhibitor consumption. A hypertension control scale was used to classify the use of antihypertensive medications and the quality of blood pressure control before and after anti-reflux surgery.Wilcoxon signed-ranks test was used for the statistical analyses. Seventy GERD patients were included in the analysis and followed up for a mean period of 3.5 ± 1.4 years. Prior to surgery, all participating patients were taking at least one class of antihypertensive medication, and 56 patients (80%) had intermittently high blood pressure. After surgery, the mean number of antihypertensive medication classes per patient was significantly reduced from 1.61 ± 0.77 pre-procedure to 1.27 ± 0.88 post-procedure (P < 0.001). The blood pressure of 48 of the 56 cases (86%) with preoperative intermittent high blood pressure returned to normal post procedure. A total of 50 patients (71%) recorded improvements on the hypertension control scale, with the overall mean score decreasing from 3.1 ± 1.0 preprocedure to 1.4 ± 1.0 post-procedure (P < 0.001). Therefore, successful laparoscopic fundoplication may result in better blood pressure control in some hypertensive GERD patients. This result suggests a possible connection between gastroesophageal reflux and hypertension.

A jackhammer in the gullet: high amplitude oesophageal contractions as a cause of atypical chest pain

Chest pain is a common cause for referral to emergency departments. A proportion of these patients have non-cardiac chest pains with normal investigations. Such patients should be considered for oesophageal studies as these may reveal an underlying dysmotility disorder. We report the case of a 51-year-old man who presented with chest pain and underwent oesophageal studies. He was diagnosed with acid reflux and high amplitude oesophageal contractions, otherwise known as a jackhammer oesophagus. Treatment was successful with omeprazole and glyceryl trinitrate relieving his symptoms.

Enterogastroesophageal reflux detected on 99m-technetium sestamibi cardiac imaging as a cause of chest pain

Myocardial perfusion imaging (MPI) with technetium-99m sestamibi (Tc-99m MIBI) is considered a diagnostic technique that is widely used for the investigation of suspected coronary artery disease. Incidental inspection of an extracardiac activity is indirect, but important marker, which can identify a potentially treatable non-coronary cause for chest pain that may mimic cardiac symptoms. Here, we present an illustrative case in which significant enterogastroesophageal reflux of Tc-99m MIBI occurred during the cardiac imaging following prompt hepatobiliary clearance. Because, there was normal myocardial perfusion on MPI, presence of gastroesophageal reflux (GER) on GER scintigraphy and detection of mild inflammation with pathologically confirmed hyperplastic polyp by endoscopy, in view of the above findings we concluded that the probable cause of chest pain was reflux.

Acid reflux in patients with coronary artery disease and refractory chest pain

OBJECTIVE

To investigate the influence of acid reflux on chest pain and ischemic events and the effects of cardiac drugs on acid reflux in patients with coronary artery disease (CAD) and refractory chest pain.

METHODS

Simultaneous 24-hour esophageal pH monitoring and 24-hour continuous electrocardiogram (ECG) (Holter) results were obtained for 64 patients. Ischemic events and cardiac drug prescriptions were compared between the patients with and without gastroesophageal reflux disease (GERD). Patients fulfilling the GERD criteria received 14-day therapy with omeprazole at a dose of 20 mg bid. The results of the 24-hour pH monitoring, Holter and the SF-36 questionnaire were compared before treatment and again after two weeks of therapy.

RESULTS

GERD was identified in 38 (69%) patients, with 49% of all chest pain occurring in association with acid reflux. A higher incidence (p=0.033) and longer duration (p=0.040) of ischemic events were observed in the GERD (+) patients. More frequent combined use of cardiac drugs was found in the GERD (+) patients. However, fewer ischemic events and greater total SF-36 survey scores were noted after PPI therapy in the GERD (+) patients.

CONCLUSION

Acid reflux is common in patients with CAD and refractory chest pain. Refractory chest pain in patients with CAD can be partially noncardiac chest pain (NCCP) secondary to acid reflux. The combined use of common cardiac drugs may predispose or aggravate GERD. Short-term proton pump inhibitor (PPI) therapy not only restores a normal esophageal pH, but also significantly improves the general health-related quality of life (HRQL) of patients.

Exertional esophageal pH-metry and manometry in recurrent chest pain

AIM: To investigate the diagnostic efficacy of 24-h and exertional esophageal pH-metry and manometry in patients with recurrent chest pain.

METHODS: The study included 111 patients (54% male) with recurrent angina-like chest pain, non-responsive to therapy with proton pump inhibitors. Sixty-five (59%) had non-obstructive lesions in coronary artery angiography, and in 46 (41%) significant coronary artery narrowing was found. In all patients, 24-h esophageal pH-metry and manometry, and treadmill stress tests with simultaneous esophageal pH-metry and manometry monitoring were performed. During a 24-h examination the percentage of spontaneous chest pain (sCP) episodes associated with acid reflux or dysmotility (symptom index, SI) was calculated. Patients with SI > 50% for acid gastroesophageal reflux (GER) were classified as having GER-related sCP. The remaining symptomatic individuals were determined as having non-GER-related sCP. During the stress test, the occurrence of chest pain, episodes of esophageal acidification (pH < 4 for 10 s) and esophageal spasm with more than 55% of simultaneous contractions (exercise-provoked esophageal spasm or EPES) were noted.

RESULTS: Sixty-eight (61%) individuals reported sCP during 24-h esophageal function monitoring. Eleven of these (16%) were classified as having GER-related sCP and 53/68 (84%) as having non-GER-related sCP. The exercise-provoked chest pain during a stress test occurred in 13/111 (12%) subjects. In order to compare the clinical usefulness of 24-h esophageal function monitoring and its examination limited only to the treadmill stress test, the standard parameters of diagnostic test evaluation were determined. The occurrence of GER-related or non-GER-related sCP was assumed as a “gold standard”. Afterwards, accuracy, sensitivity and specificity were calculated. These parameters expressed a prediction of GER-related or non-GER-related sCP occurrence by the presence of chest pain, esophageal acidification and EPES. Accuracy, sensitivity and specificity of chest pain during the stress test predicting any sCP occurrence were 28%, 35% and 80%, respectively, predicting GER-related sCP were 42%, 0% and 83%, respectively, and predicting non-GER-related sCP were 57%, 36% and 83%, respectively. Similar values were obtained for exercise-related acidification with pH < 4 longer than 10 s in the prediction of GER-related sCP (44%, 36% and 92%, respectively) and EPES in relation to non-GER-related sCP (48%, 23% and 84%, respectively).

CONCLUSION: The presence of chest pain, esophageal acidification and EPES had greater than 80% specificity to exclude the GER-related and non-GER-related causes of recurrent chest pain.

Noncardiac chest pain: gastroesophageal reflux disease

Noncardiac chest pain (NCCP) is not only a difficult disorder to define but is also complex in characterization and treatment. Patients with NCCP are a challenge to primary care and subspecialty services such as cardiology and gastroenterology. NCCP is often a heterogeneous disorder with many potential causes including gastroenterologic diagnoses. This article presents the current evidence for gastroesophageal reflux disease as a cause of NCCP and highlights the best currently available tests for this group of patients.
