Røysland IØ, Patel H. Experiences of unexplained chest pain and physical activity: A Meta-Ethnography. J Clin Nurs 2022. [PMID: 36028954 DOI: 10.1111/jocn.16496] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Revised: 07/27/2022] [Accepted: 08/11/2022] [Indexed: 12/01/2022]
Abstract
AIMS AND OBJECTIVES The aim was to examine the experiences of physical activity in the patients with unexplained chest pain. BACKGROUND Previous qualitative studies have compiled data on the physical activity experiences of people with unexplained chest pain. Nevertheless, no meta-synthesis exists on this topic to advance the theoretical development of future-related studies. DESIGN A meta-ethnographic synthesis of qualitative studies was conducted. Original qualitative studies on the physical activity experiences of people with unexplained chest pain were identified and systematically synthesised using a meta-ethnographic approach. METHODS Seven databases were searched for relevant full-text articles in English, Danish, Norwegian and Swedish. There were no limitations concerning year of publication. Articles were first screened against inclusion criteria for eligibility and then assessed for quality and analysed using Noblit and Hare's seven-step meta-ethnography process. The ENTREQ checklist for systematic reviews was used. RESULTS Nine qualitative studies were included in the analysis. The physical activity experiences of people with unexplained chest pain illuminates the metaphor: "Physical activity means balancing uncertainty" with four themes: looking for possible explanations, feeling vulnerable, feeling uncertain of consequences and being physically active may mean becoming more capable. CONCLUSION For people with unexplained chest pain, being physically active meant moving toward being more capable. The participants felt vulnerable and physical activity helped in balancing uncertainty. A comprehensive model illustrates the antecedents and succedent for the physical activity experiences of individuals with unexplained chest pains. RELEVANCE TO CLINICAL PRACTICE An approach to care which considers the patient's experience might be applicable; however, it needs to be accompanied with a biomedical perspective. Nurses and other health professionals need to provide a bridge between the patient's experiences and health professionals' advice and recommendations.

J Pain Res 2021; 14:827-835. [PMID: 33833560 PMCID: PMC8019660 DOI: 10.2147/jpr.s303186] [Citation(s) in RCA: 35] [Impact Index Per Article: 11.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2021] [Accepted: 03/16/2021] [Indexed: 11/23/2022] Open
Abstract
Chronic pain is nowadays used as an umbrella term referring to a wide range of clinical conditions, such as fibromyalgia, migraine, or long-standing pain states without actual known causes. However, labeling a patient’s clinical condition with the term “chronic pain”, when dealing with pain lasting longer than 3 months, might be misleading. This paper aims at analyzing the possible pitfalls related to the use of the term “chronic pain” in the clinical field. It appears, indeed, that the term “chronic pain” shows a semantic inaccuracy on the basis of emerging scientific evidences on the pathogenesis of different long-standing pain states. The major pitfalls in using this label emerge in clinical settings, especially with patients having a biomedical perspective on pain or from different cultures, or with healthcare providers of other medical specialties or different disciplines. A label solely emphasizing temporal features does not help to discern the multifaceted complexity of long-standing pain states, whose onset, maintenance and exacerbation are influenced by a complex and interdependent set of bio-psycho-social factors. Thus, finding a more meaningful name might be important. We call upon the necessity of bringing awareness and implementing educational activities for healthcare providers, as well as for the public, on the biopsychosocial approach to assess, prevent and care of chronic pain. Further research on the etiopathogenetic processes of chronic pain states is also required, together with examinative diagnostic methods, to individuate the most appropriate label(s) representing the complex long-standing pain states and to avoid adopting the term “chronic pain” inappropriately.

Abstract
AbstractMany individuals presenting to medical settings with heart-related symptoms for which no medical explanation is found might suffer from cardiophobia, but this condition is still poorly identified and addressed. This article presents a case of cardiophobia treated in an outpatient cardiac rehabilitation unit and, for the first time, describes the application of brief strategic therapy for the treatment of this condition. In the case reported, the first therapeutic encounter and the key elements of the strategic approach are described in detail with the aim to explain how brief strategic therapy works and how it can be used to identify and address cardiophobia-related behaviors. A 64-year-old male presented to cardiac rehabilitation reporting intense anxiety-provoking heart palpitations, and believing he was at risk of dying from a heart attack. After 3 sessions, an overall improvement in heart-related bodily sensations followed a decrease in the patient’s continuous checking of his heartbeat and seeking reassurance—factors that were largely responsible for the persistence of the problem. Moreover, quantitative evaluation showed increased scores of mood state at the end of treatment. This improvement persisted at the 18-month follow-up. This case is an interesting example of how brief strategic therapy can contribute to the development of a new conceptual model for the diagnosis and treatment of cardiophobia. Still, more systematic research in the field is needed to prove the efficacy and effectiveness of this therapeutic approach on symptoms of heart-focused anxiety.

Risk of Myocardial Infarction in Patients Without Angiographic Coronary Artery Disease Compared With the General Population. Am J Cardiol 2020; 132:8-14. [PMID: 32773225 DOI: 10.1016/j.amjcard.2020.06.068] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/22/2020] [Revised: 06/25/2020] [Accepted: 06/30/2020] [Indexed: 11/20/2022]
Abstract
We examined the 10-year risk of myocardial infarction (MI) and death in patients without obstructive coronary artery disease (CAD) compared with the general population. We conducted a cohort study of every patient without obstructive CAD by coronary angiography (CAG) between 2003 and 2016 in Western Denmark. Patients were matched by gender and age with individuals from the general population of Western Denmark with no history of CAD. End points were MI and death. Ten-year risk differences in cumulative incidence proportions were computed, accounting for the competing risk of death in the case of MI. Unadjusted and adjusted incidence rate ratios (aIRRs) were estimated using conditional Poisson regression. We included 46,467 patients and 234,654 individuals from the general population. Median follow-up was 7.7 years. The 10-year cumulative incidence of MI was 2.40% (95% confidence interval [CI] 2.24 to 2.57) in patients without obstructive CAD in the CAG and 2.70% (95% CI 2.62 to 2.78) in the general population, with a reduced absolute 10-year risk (risk difference -0.30%, 95% CI -0.49 to -0.12) and a reduced aIRR (aIRR 0.70, 95% CI 0.63 to 0.77). Ten-year mortality was higher in patients without obstructive CAD in the CAG (21.44%, 95% CI 20.99 to 21.89) compared with the general population (17.25%, 95% CI 17.06 to 17.44). However, mortality rates were similar after adjustment (aIRR 1.00, 95% CI 0.96 to 1.02). In conclusion, the absence of obstructive CAD according to CAG is associated with a lower risk of MI than in the general population, and similar 10-year mortality.

Non-cardiac chest pain patients in the emergency department: Do physicians have a plan how to diagnose and treat them? A retrospective study. PLoS One 2019; 14:e0211615.

Abstract
BACKGROUND Non-cardiac chest pain is common and there is no formal recommendation on what diagnostic tests to use to identify underlying diseases after an acute coronary syndrome has been ruled out. OBJECTIVE To evaluate the diagnostic tests, treatment recommendations and initiated treatments in patients presenting with non-cardiac chest pain to the emergency department (ED). METHODS Single-center, retrospective medical chart review of patients presenting to the ED. Included were all medical records of patients aged 18 years and older presenting to the ED with chest pain and a non-cardiac discharge diagnosis between January 1, 2009 and December 31, 2011. Information on the diagnosis, diagnostic tests performed, treatment initiated and recommendation for further diagnostic testing or treatment were extracted. The primary outcomes of interest were the final diagnosis, diagnostic tests, and treatment recommendations. A formal ACS rule out testing was defined as serial three troponin testing. RESULTS In total, 1341 ED admissions for non-cardiac chest pain (4.2% of all ED admissions) were analyzed. Non-specific chest pain remained the discharge diagnosis in 44.7% (n = 599). Identified underlying diseases included musculoskeletal chest pain (n = 602, 44.9%), pulmonary (n = 30, 2.2%), GI-tract (n = 35, 2.6%), or psychiatric diseases (n = 75, 5.6%). In 81.4% at least one troponin test and in 89% one ECG were performed. A formal ACS rule out troponin testing was performed in 9.2% (GI-tract disease 14.3%, non-specific chest pain 14.0%, pulmonary disease 10.0%, musculoskeletal chest pain 4.7%, and psychiatric disease 4.0%). Most frequently analgesics were prescribed (51%). A diagnostic test with proton pump inhibitor (PPI) was prescribed in 20% (mainly in gastrointestinal diseases). At discharge, over 72 different recommendations were given, ranging from no further measures to extensive cardiac evaluation. CONCLUSION In this retrospective study, a formal work-up to rule out ACS was found in a minority of patients presenting to the ED with chest pain of non-cardiac origin. A wide variation in diagnostic processes and treatment recommendations reflect the uncertainty of clinicians on how to approach patients after a cardiac cause was considered unlikely. Panic and anxiety disorders were rarely considered and a useful PPI treatment trial to diagnose gastroesophageal reflux disease was infrequently recommended.

Abstract
INTRODUCTION Overuse of cardiac catheterisation (CC) for stable coronary artery disease (CAD) is documented in Germany and other regions, although percutaneous coronary interventions do not provide a benefit over medical therapy for stable patients. Various studies investigated health system, physician and patient factors driving non-adherence to guidelines which recommend a stepwise approach with invasive procedures only in case of signs of ischaemia in non-invasive testing. In a larger-scale project, we aim to better understand the patients' perspective in order to develop an intervention that enhances patient's acceptance of this stepwise diagnostic approach for stable CAD. As a first step, this qualitative study aims to identify patient factors that prevent and promote the described overuse. METHODS AND ANALYSIS The exploratory qualitative interview study will include about 20 patients with stable CAD and a history of acute coronary syndrome from two German teaching practices. Narrative, structured interviews designed to last 30 to 90 min will be conducted. The interviews will be analysed using qualitative content analysis by Mayring. The analysis will address the following questions: (1) What are reasons for stable patients to undergo CC? (2) How do patients deal with their heart disease (secondary prevention)? (3) Which processes do patients describe regarding decision-making for non-invasive and invasive coronary procedures? (4) What information needs exist on behalf of patients to better understand the stepwise diagnostic approach outlined in guidelines and thereby avoid low-appropriate CCs? Based on these data, empirical typification will be conducted. ETHICS AND DISSEMINATION Ethical approval for the study was obtained. All participants will provide written informed consent. Data will be pseudonymised for analysis. The findings will contribute to the development of an appropriate intervention. Results will be disseminated by conference presentations and journal publications.

Abstract
UNLABELLED Non-invasive imaging plays a critical role in the assessment of patients presenting with suspected angina chest pain. However, wide variations in practice across Europe and North America highlight the lack of consensus in selecting the appropriate first-line test for the investigation of coronary artery disease (CAD). CT coronary angiography (CTCA) has a high negative predictive value for excluding the presence of CAD. As such, it serves as a potential 'gatekeeper' to downstream testing by reducing the rate of inappropriate invasive coronary angiography. Two recent large multicentre randomised control trials have provided insights into whether CTCA can be incorporated into chest pain care pathways to improve risk stratification of CAD. They demonstrate that using CTCA enhances diagnostic certainty and improves the targeting of appropriate invasive investigations and therapeutic interventions. Importantly, reductions in cardiac death and non-fatal myocardial infarction appear to be attained through the more appropriate use of preventative therapy and coronary revascularisation when guided by CTCA. With this increasing portfolio of evidence, CTCA should be considered the non-invasive investigation of choice in the evaluation of patients with suspected angina pectoris due to coronary heart disease. CLINICAL TRIAL NUMBER NCT01149590, post-results.

Abstract
Background Recurrent chest pain is common in patients with and without coronary artery disease. The prevalence and burden of these symptoms on healthcare is unknown. Objectives To compare chest pain return visits (recidivism) in patients with unexplained chest pain (UCP) against reference group of patients with coronary artery disease (CAD) and estimate the annual cost of recurrent chest pain. Methods In a retrospective cohort study, a Veteran Affairs (VA) administrative and clinical database of Veterans who were deployed to or served in support of the wars in Iraq or Afghanistan was queried for first disease specific ICD-9 code to form two cohorts (UCP or CAD). Patients were followed between 09/2001-09/2010 for the first and cumulative return visits for UCP or cardiac pain (ACS or angina) to clinic, emergency department or admission; or for all-cause death. Time to return was analyzed using Cox regression and negative binomial models and adjusted for age, gender, race, marital status, and risk factors (hypertension, hyperlipidemia, diabetes, smoking and obesity). Direct total costs included inpatient, outpatient and fee basis (non-VA) costs. Results Of 749,036 patients, 20,521 had UCP and 5303 had CAD. UCP patients were young and had a lower burden of risk factors than CAD cohort (p < .01). Yet, these patients were likely to return earlier with any chest pain (adjusted Hazard Ratio [aHR] = 1.76; 95 % CI 1.65-1.88); or unexplained chest pain than CAD patients (aHR: 1.89; 95 % CI 1.77-2.01). UCP patients were also likely to return more frequently for any chest pain (aRate Ratio = 1.54; 95 % CI 1.43-1.64) or UCP than CAD patients (aRR =2.63; 95 % CI 2.43-2.87). Per 100 patients, the 1-year cumulative returns were 37 visits for reference group and 45 visits for UCP cohort. The annual costs for chest pain averaged $69,009 for CAD and $57,336 for UCP patients (log geometric mean ratio=1.25; 95 % CI 1.18-1.32). Conclusion Chest pain recidivism is common and costly even in patients without known CAD. We need evidence-based guidelines for these patients to minimize returns.

Abstract
BACKGROUND Recurrent chest pain in the absence of coronary artery disease is a common problem which sometimes leads to excess use of medical care. Although many studies have examined the causes of pain in these patients, few clinical trials have evaluated treatment. This is an update of a Cochrane review originally published in 2005 and last updated in 2010. The studies reviewed in this paper provide an insight into the effectiveness of psychological interventions for this group of patients. OBJECTIVES To assess the effects of psychological interventions for chest pain, quality of life and psychological parameters in people with non-specific chest pain. SEARCH METHODS We searched the Cochrane Library (CENTRAL, Issue 4 of 12, 2014 and DARE Issue 2 of 4, 2014), MEDLINE (OVID, 1966 to April week 4 2014), EMBASE (OVID, 1980 to week 18 2014), CINAHL (EBSCO, 1982 to April 2014), PsycINFO (OVID, 1887 to April week 5 2014) and BIOSIS Previews (Web of Knowledge, 1969 to 2 May 2014). We also searched citation lists and contacted study authors. SELECTION CRITERIA Randomised controlled trials (RCTs) with standardised outcome methodology that tested any form of psychotherapy for chest pain with normal anatomy. Diagnoses included non-specific chest pain (NSCP), atypical chest pain, syndrome X or chest pain with normal coronary anatomy (as either inpatients or outpatients). DATA COLLECTION AND ANALYSIS Two review authors independently selected studies for inclusion, extracted data and assessed quality of studies. We contacted trial authors for further information about the included RCTs. MAIN RESULTS We included two new papers, one of which was an update of a previously included study. Therefore, a total of 17 RCTs with 1006 randomised participants met the inclusion criteria, with the one new study contributing an additional 113 participants. There was a significant reduction in reports of chest pain in the first three months following the intervention: random-effects relative risk = 0.70 (95% CI 0.53 to 0.92). This was maintained from three to nine months afterwards: relative risk 0.59 (95% CI 0.45 to 0.76). There was also a significant increase in the number of chest pain-free days up to three months following the intervention: mean difference (MD) 3.00 (95% CI 0.23 to 5.77). This was associated with reduced chest pain frequency (random-effects MD -2.26, 95% CI -4.41 to -0.12) but there was no evidence of effect of treatment on chest pain frequency from three to twelve months (random-effects MD -0.81, 95% CI -2.35 to 0.74). There was no effect on severity (random-effects MD -4.64 (95% CI -12.18 to 2.89) up to three months after the intervention. Due to the nature of the main interventions of interest, it was impossible to blind the therapists as to whether the participant was in the intervention or control arm. In addition, in three studies the blinding of participants was expressly forbidden by the local ethics committee because of issues in obtaining fully informed consent . For this reason, all studies had a high risk of performance bias. In addition, three studies were thought to have a high risk of outcome bias. In general, there was a low risk of bias in the other domains. However, there was high heterogeneity and caution is required in interpreting these results. The wide variability in secondary outcome measures made it difficult to integrate findings from studies. AUTHORS' CONCLUSIONS This Cochrane review suggests a modest to moderate benefit for psychological interventions, particularly those using a cognitive-behavioural framework, which was largely restricted to the first three months after the intervention. Hypnotherapy is also a possible alternative. However, these conclusions are limited by high heterogeneity in many of the results and low numbers of participants in individual studies. The evidence for other brief interventions was less clear. Further RCTs of psychological interventions for NSCP with follow-up periods of at least 12 months are needed.

Abstract
BACKGROUND Patients with unexplained chest pain are commonly revisiting an emergency department with various symptoms, but comprehensive long-term studies are lacking. METHODS A total of 150 young adults (aged 18-40 years) with unexplained chest pain who presented at an emergency unit for 16 weeks in mid-1980s were included in a prospective cohort study. An age- and sex-matched control group was randomly selected from the same area. Data were retrieved from registers that recorded death, income, education, country of birth, diagnoses, hospitalizations, outpatient visits, and medications dispensed. RESULTS Patients with unexplained acute chest pain had lower levels of education and income and were more often immigrants. Long-term mortality rates did not differ between cases (4%) and controls (5%) during 25 years of follow-up, nor were there differences in diagnosis of ischemic heart disease. Patients with unexplained acute chest pain had more outpatient visits (median, 5 versus 2; p < .0001) and had more often been hospitalized (61.6% ever versus 41.8%; p < .001) during the follow-up period. Several disorders were more common among patients 20 to 25 years later, including atrial fibrillation, esophageal/gastric disorders, chest pain, palpitations, abdominal discomfort, musculoskeletal symptoms, sleeping disturbance, and stress reactions (p values < .05). More patients had been given antihypertensives, anticoagulants, antidepressants, analgesics, and hypnotics/tranquilizers (p values < .05). CONCLUSIONS Young patients admitted to the emergency department with unexplained acute chest pain showed no increased risk of mortality or ischemic heart disease during 25 years of follow-up, but they had higher incidence of a wide range of disorders and used more medications. Early identification and preventive interventions may improve health outcomes in these patients.

Abstract
BACKGROUND More than 20% of patients presenting to the cardiac catheterization laboratory with angina have no angiographic evidence of coronary artery disease. Despite a "normal" angiogram, these patients often have persistent symptoms, recurrent hospitalizations, a poor functional status, and adverse cardiovascular outcomes, without a clear diagnosis. METHODS AND RESULTS In 139 patients with angina in the absence of obstructive coronary artery disease (no diameter stenosis >50%), endothelial function was assessed; the index of microcirculatory resistance, coronary flow reserve, and fractional flow reserve were measured; and intravascular ultrasound was performed. There were no complications. The average age was 54.0±11.4 years, and 107 (77%) were women. All patients had at least some evidence of atherosclerosis based on an intravascular ultrasound examination of the left anterior descending artery. Endothelial dysfunction (a decrease in luminal diameter of >20% after intracoronary acetylcholine) was present in 61 patients (44%). Microvascular impairment (an index of microcirculatory resistance ≥25) was present in 29 patients (21%). Seven patients (5%) had a fractional flow reserve ≤0.80. A myocardial bridge was present in 70 patients (58%). Overall, only 32 patients (23%) had no coronary explanation for their angina, with normal endothelial function, normal coronary physiological assessment, and no myocardial bridging. CONCLUSIONS The majority of patients with angina in the absence of obstructive coronary artery disease have occult coronary abnormalities. A comprehensive invasive assessment of these patients at the time of coronary angiography can be performed safely and provides important diagnostic information that may affect treatment and outcomes.

Abstract
Cardiophobic persons repeatedly present with complaints of chest pain and heart palpitations accompanied by fears of having a heart attack and of dying. They focus attention on their heart when experiencing stress and arousal, perceive its function in a phobic manner, and continue to believe they suffer from an organic heart problem despite repeated negative medical tests. To reduce anxiety, they seek continuous reassurance, make excessive use of medical facilities, and avoid activities believed to bring on symptoms. This article analyses the evidence for viewing cardiophobia as a phobic disorder in its own right rather than merely a problem of non-organic chest pain with some overlay of anxiety and depression. Despite some overlapping symptoms shared with persons who suffer from panic disorder, illness phobia, and extreme health anxiety, a number of central and defining features of cardiophobia are identified to differentiate cardiophobia from other anxiety disorders. An integrative model for understanding the origin and maintenance of cardiophobia (Eifert, 1990) is summarised and some treatment recommendations are derived from this model to target the central problems of persons with cardiophobia. Directions for future research are also discussed.

Abstract
BACKGROUND & AIMS Chest pain is a common and frightening symptom. Once cardiac disease has been excluded, an esophageal source is most likely. Pathophysiologically, gastroesophageal reflux disease, esophageal dysmotility, esophageal hypersensitivity, and anxiety disorders have been implicated. However, treatment remains a challenge. Here we examined the efficacy and safety of various commonly used modalities for treatment of esophageal (noncardiac) chest pain (ECP) and provided evidence-based recommendations. METHODS We reviewed the English language literature for drug trials evaluating treatment of ECP in PubMed, Cochrane, and MEDLINE databases from 1968-2012. Standard forms were used to abstract data regarding study design, duration, outcome measures and adverse events, and study quality. RESULTS Thirty-five studies comprising various treatments were included and grouped under 5 broad categories. Patient inclusion criteria were extremely variable, and studies were generally small with methodological concerns. There was good evidence to support the use of omeprazole and fair evidence for lansoprazole, rabeprazole, theophylline, sertraline, trazodone, venlafaxine, imipramine, and cognitive behavioral therapy. There was poor evidence for nifedipine, diltiazem, paroxetine, biofeedback therapy, ranitidine, nitrates, botulinum toxin, esophageal myotomy, and hypnotherapy. CONCLUSIONS Ideally, treatment of ECP should be aimed at correcting the underlying mechanism(s) and relieving symptoms. Proton pump inhibitors, antidepressants, theophylline, and cognitive behavioral therapy appear to be useful for the treatment of ECP. However, there is urgent and unmet need for effective treatments and for rigorous, randomized controlled trials.

Abstract
OBJECTIVE Many patients who attend an emergency department (ED) with chest pain receive a diagnosis of non-cardiac chest pain (NCCP), and often suffer poor psychological outcomes and continued pain. This study assessed the role of illness representations in explaining psychological distress and continued chest pain in patients attending an ED. METHODS ED NCCP patients (N = 138) completed measures assessing illness representations, anxiety, depression and quality of life (QoL) at baseline, and chest pain at one month. RESULTS Illness representations explained significant amounts of the variance in anxiety (Adj. R² = .38), depression (Adj. R² = .18) and mental QoL (Adj. R² = .36). A belief in psychological causes had the strongest associations with outcomes. At one month, 28.7% of participants reported experiencing frequent pain, 13.2% infrequent pain and 58.1% no pain. Anxiety, depression and poor QoL, but not illness representations, were associated with continued chest pain. CONCLUSIONS The findings suggest that (i) continued chest pain is related to psychological distress and poor QoL, (ii) interventions should be aimed at reducing psychological distress and improving QoL and (iii) given the associations between perceived psychological causes and psychological distress/QoL, NCCP patients in the ED might benefit from psychological therapies to manage their chest pain.

Abstract
Approximately 20% of patients undergoing diagnostic angiography for the evaluation of chest pain are found to have a normal coronary angiogram. Although this finding is generally associated with a low risk of cardiac events, approximately half will continue to experience chest pain over the next 12 months. Therefore, the finding of normal angiography warrants further evaluation of the potential causes for the presenting chest pain if we are to improve the disability suffered by these patients. In this review, the potential non-cardiac and cardiac causes for the chest pain in patients with normal angiography are briefly discussed with an in-depth focus on coronary vasomotor disorders including coronary artery spasm (variant angina) and microvascular disorders such as syndrome X, microvascular angina, the coronary slow flow phenomenon and microvascular spasm.

Abstract
OBJECTIVES Intact esophageal mucosal integrity is essential to prevent symptoms during gastroesophageal reflux events. Approximately 70% of patients with heartburn have macroscopically normal esophageal mucosa. In patients with heartburn, persistent functional impairment of esophageal mucosal barrier integrity may underlie remaining symptoms. Topical protection of a functionally vulnerable mucosa may be an attractive therapeutic strategy. We aimed to evaluate esophageal mucosal functional integrity in patients with heartburn without esophagitis, and test the feasibility of an alginate-based topical mucosal protection. METHODS Three distal esophageal biopsies were obtained from 22 patients with heartburn symptoms, and 22 control subjects. In mini-Ussing chambers, the change in transepithelial electrical resistance (TER) of biopsies when exposed to neutral, weakly acidic, and acidic solutions was measured. The experiment was repeated in a further 10 patients after pretreatment of biopsies with sodium alginate, viscous control, or liquid control "protectant" solutions. RESULTS Biopsy exposure to neutral solution caused no change in TER. Exposure to weakly acidic and acidic solutions caused a greater reduction in TER in patients than in controls (weakly acid -7.2% (95% confidence interval (CI) -9.9 to -4.5) vs. 3.2% (-2.2 to 8.6), P<0.05; acidic -22.8% (-31.4 to 14.1) vs. -9.4% (-17.2 to -1.6), P<0.01). Topical pretreatment with alginate but not with control solutions prevented the acid-induced decrease in TER (-1% (-5.9 to 3.9) vs. -13.5 (-24.1 to -3.0) vs. -13.2 (-21.7 to -4.8), P<0.05). CONCLUSIONS Esophageal mucosa in patients with heartburn without esophagitis shows distinct vulnerability to acid and weakly acidic exposures. Experiments in vitro suggest that such vulnerable mucosa may be protected by application of an alginate-containing topical solution.

Abstract
Non-cardiac chest pain is common. It has a low risk of coronary events, but causes considerable physical and social disability and inappropriate health-care usage. It is a heterogeneous condition, which may be caused by or associated with gastro-oesophageal, musculoskeletal or psychiatric abnormalities and sustained by psychological factors including catastrophisation, avoidance behaviour and abnormal help-seeking. These may coexist and their relative contributions may vary in different patients or at different times in an individual patient. The absence of a unitary cause probably explains why treatment studies show only moderate success. An individualised biopsychosocial approach takes account of all causative and sustaining processes and has been shown to work in pain syndromes at other sites. We suggest that this approach should be tried for chest pain using a multidisciplinary clinic model including cardiologists, psychologists and nurses linked with a Rapid Access Chest Pain Clinic.

Abstract
Chest pain can be a frightening experience that leads many to seek medical evaluation. The symptom results in costly health care utilisation. Over half of patients referred for cardiac evaluations of chest pain do not obtain definitive medical explanations for their symptoms; these cases are described as non-cardiac chest pain (NCCP). Some patients with NCCP are not reassured after being informed their chest pain is non-cardiac in origin and seek repeated medical evaluation. Co-morbid anxiety and mood disorders often coexist with NCCP and are associated with health care utilisation. The current study examined chest pain, general anxiety, interoceptive fear and health care utilisation in a sample of 196 chest pain patients near the time of cardiac evaluation (Time 1), and 70 of these patients one year later (Time 2). Results indicate that anxiety and interoceptive fear were significantly associated with health care utilisation at Time 1, and only interoceptive fear (at Time 1) predicted health care utilisation at Time 2. This study develops research in this area by examining the relation of anxiety and health care utilisation longitudinally in patients with NCCP.

Abstract
OBJECTIVES We previously reported that 25% (108/441) of consecutive patients presenting to the emergency department (ED) of the Montreal Heart Institute with a chief complaint of chest pain suffered from panic disorder (PD). The purpose of the present study was to re-examine these patients (with and without PD) 2 years after their initial ED visit to determine their psychiatric and psychosocial status. METHODS An interviewer, who was kept blind to patients' initial medical and psychiatric diagnoses, attempted to contact all patients who participated in the initial study by phone. Patients who completed the phone interview were sent a battery of psychological questionnaires by mail. RESULTS A total of 301 (70%) patients completed the phone interview, and 228 (52%) patients completed the self-report questionnaires. Participants and non-participants did not differ with respect to age, gender, initial self-report scores, or initial cardiac or psychiatric diagnoses. At follow-up, significantly (p < 0.05) more PD+ than non-PD (PD-) patients reported: 1) chest pains in the last month (57% vs. 31%); 2) one or more ED consultations in the past year for chest pain (40% vs. 14%); 3) one or more hospitalizations in the past year (31% vs. 11%); and 4) perceiving their general health as "poor" (22% vs. 9%). PD+ patients displayed a significant (p < 0.05) worsening of their panic symptoms, agoraphobic avoidance, depression, and trait anxiety, and reported significantly (p < 0.05) greater suicidal ideation compared to PD- patients (32% vs. 9%). Of all PD+ patients, only 22% (18/82) reported receiving some form of mental health treatment for their symptoms. CONCLUSIONS Unrecognized and untreated PD has a chronic and disabling course. Greater efforts should be made to screen for PD in patients complaining of chest pain in EDs.

Abstract
BACKGROUND Recurrent chest pain in the absence of coronary artery disease is a common problem that sometimes leads to excess use of medical care. Although many studies examine the causes of pain in these patients, few clinical trials have evaluated treatment. The studies reviewed in this paper provide an insight into the effectiveness of psychological interventions for this group of patients. OBJECTIVES To update the previously published systematic review. SEARCH METHODS We searched the Cochrane LIbrary (CENTRAL and DARE) (Issue 3 of 4 2011), MEDLINE (1966 to August Week 5, 2011), CINAHL (1982 to Sept 2011) EMBASE (1980 to Week 35 2011), PsycINFO (1887 to Sept Week 1, 2011), and Biological Abstracts (January 1980 to Sept 2011). We also searched citation lists and approached authors. SELECTION CRITERIA Randomised controlled trials (RCTs) with standardised outcome methodology that tested any form of psychotherapy for chest pain with normal anatomy. Diagnoses included non-specific chest pain (NSCP), atypical chest pain, syndrome X, or chest pain with normal coronary anatomy (as either inpatients or outpatients). DATA COLLECTION AND ANALYSIS Two authors independently selected studies for inclusion, extracted data and assessed quality of studies. The authors contacted trial authors for further information about the RCTs included. MAIN RESULTS Six new RCTs were located and added to the existing trials, therefore, a total of 15 RCTs (803 participants) were included. There was a significant reduction in reports of chest pain in the first three months following the intervention; fixed-effect relative risk = 0.68 (95% CI 0.57 to 0.81). This was maintained from three to nine months afterwards; relative risk = 0.59 (95% CI 0.45 to 0.76). There was also a significant increase in the number of chest pain free days up to three months following the intervention; mean difference = 2.81 (95% CI 1.28 to 4.34). This was associated with reduced chest pain frequency (random-effects mean difference = -2.26 95% CI -4.41 to -0.12) but there was no evidence of effect of treatment on chest pain frequency from three to twelve months (random-effects mean difference -0.81 95% CI -2.35, 0.74). There was no effect on severity (random-effects mean difference = -4.64 (95% CI -12.18 to 2.89) up to three months after the intervention. Overall there was generally a low risk of bias, however, there was high heterogeneity and caution is required in interpreting these results. Wide variability in outcome measures made integration of studies for secondary outcome measures difficult to report on. AUTHORS' CONCLUSIONS This review suggests a modest to moderate benefit for psychological interventions, particularly those using a cognitive-behavioural framework, which was largely restricted to the first three months after the intervention. Hypnotherapy is also a possible alternative. The evidence for brief interventions was less clear. Further RCTs of psychological interventions for NSCP with follow-up periods of at least 12 months are needed.

Abstract
Noncardiac chest pain (NCCP) is very prevalent in the community. Although mortality remains low, morbidity and the financial implications are high. Women, especially those of middle age, should be thoroughly investigated as per current guidelines for coronary artery disease before labeling their chest pain as NCCP. Gastroesophageal reflux disease is the most common cause of NCCP; however other esophageal pathology including esophageal hypersensitivity, neuromuscular disease and eosinophilic esophagitis may also cause NCCP. Proton pump inhibitors are commonly used initially to manage NCCP, although patients who do not respond to this therapy require further investigation and differing treatment regimes. This article will focus on current knowledge regarding GI tract-related NCCP management strategies.

Abstract
The aim of this study was to examine independent and combined influences of alexithymia and anxiety sensitivity on chest pain and life interference in patients with non-cardiac chest pain (NCCP). Theories of NCCP posit a central role for emotion in the experience of chest pain, however, studies have not examined how alexithymia characterized by a difficulty identifying or verbalizing emotions, may influence this relationship. This study examined 231 patients (56% females, M age=50 years) with chest pain seeking cardiac evaluation, who showed no abnormalities during exercise tolerance testing. Forty percent (40%) scored at or above the moderate range of alexithymia. Whereas health care utilization was associated with elevated alexithymia among men, health care utilization was associated with elevated anxiety sensitivity among women. Hierarchical regression analyses revealed that alexithymia and anxiety sensitivity were both uniquely and independently associated with pain severity and life interference due to pain. Alexithymia-pain links were stronger for men compared to women. Secondary analyses conducted with a subsample suggest that alexithymia may be increasingly stable over time (i.e., 18-month follow-up). Findings are largely congruent with theoretical models of NCCP showing that personality and emotional factors are important in this medically unexplained syndrome.

Abstract
BACKGROUND Microvascular coronary dysfunction (MCD) is associated with symptoms and signs of ischemia, and also adverse outcomes in women without macrovascular obstructive coronary artery disease (M-CAD). Although MCD can be quantified using coronary flow reserve (CFR), treatment is poorly defined. HYPOTHESIS Phosphodiesterase type 5 (PDE-5) inhibition acutely improves MCD in these women. METHODS The subjects were 23 symptomatic women (age 54 ± 11 y) participating in an ancillary study of the Women's Ischemia Syndrome Evaluation with baseline CFR ≤3.0 (Doppler flow wire and intracoronary adenosine) and without M-CAD. Coronary flow reserve was remeasured 45 minutes after PDE-5 inhibition (100 mg oral sildenafil). The primary measure of interest was change in CFR adjusted for baseline variables. RESULTS The relationship between log(2)-transformed CFR post-PDE-5 inhibition (adjusted) and baseline was different from the line of identity (slope: 0.55 vs 1.0, P = 0.008; intercept: 0.73 vs 0.0, P = 0.01), indicating that PDE-5 inhibition improves CFR and the lower the baseline CFR, the greater the response. Among women with baseline CFR ≤2.5 (n = 11), CFR increased from 2.1 ± 0.2 to 2.7 ± 0.6 (P = 0.006). For women with baseline CFR >2.5 (n = 12), CFR did not change (3.1 ± 0.3 to 3.0 ± 0.6; P = 0.70). CONCLUSIONS For women with symptoms and signs of ischemia and no M-CAD, PDE-5 inhibition is associated with acute improvement in CFR, and the effect concentrates among those with CFR ≤2.5. If these acute effects are sustained, then PDE-5 inhibition would provide a rational strategy for management of MCD in symptomatic women without M-CAD. The longer-term effects warrant study in a randomized trial using a sustained-acting PDE-5 inhibitor.

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
OBJECTIVES Esophageal hypersensitivity is currently believed to have a crucial role in the pathogenesis of functional chest pain (FCP). The aim of this study was to evaluate the clinical efficacy of venlafaxine, a serotonin-norepinephrine reuptake inhibitor (SNRI), for FCP in young adult patients. METHODS Patients diagnosed with FCP were randomized to either an extended-release formulation of venlafaxine (75 mg hora somni) or a placebo for 4 weeks. After a washout period of 2 weeks, patients crossed over to the other arm of the study. The primary efficacy variable was the number of patients with >50% improvement in symptom scores. The secondary efficacy variables were (i) the symptom intensity score during each week, (ii) quality of life (QOL), (iii) the Beck Depression Inventory (BDI) score, and (iv) side effects. RESULTS A total of 43 patients (37 men, mean age 23.5 + or - 1.9 years) completed the study. A positive response was observed in 52.0% of patients during venlafaxine treatment; 4.0% had a positive response with placebo treatment as assessed by the intention-to-treat analysis (venlafaxine vs. placebo: odds ratio 26.0; 95% confidence interval 5.7-118.8; P<0.001). Results of Short-Form 36 (SF-36) indicated that patients who received venlafaxine treatment had a significantly greater improvement in body pain and emotional role compared with those who received placebo treatment (P=0.002 and P=0.002, respectively). No significant change was noted in the depression score after venalafaxine or placebo treatment. One patient withdrew from the study because of sleep disturbance and loss of appetite while receiving venlafaxine. CONCLUSIONS Venlafaxine, an SNRI antidepressant, significantly improved symptoms in young adult patients with FCP.

Abstract
The musculoskeletal system is a recognized source of chest pain. However, despite the apparently benign origin, patients with musculoskeletal chest pain remain under-diagnosed, untreated, and potentially continuously disabled in terms of anxiety, depression, and activities of daily living. Several overlapping conditions and syndromes of focal disorders, including Tietze syndrome, costochondritis, chest wall syndrome, muscle tenderness, slipping rib, cervical angina, and segmental dysfunction of the cervical and thoracic spine, have been reported to cause pain. For most of these syndromes, evidence arises mainly from case stories and empiric knowledge. For segmental dysfunction, clinical features of musculoskeletal chest pain have been characterized in a few clinical trials. This article summarizes the most commonly encountered syndromes of focal musculoskeletal disorders in clinical practice.

Abstract
The management of patients with chest pain is a common and challenging clinical problem. Although most of these patients do not have a life-threatening condition, the clinician must distinguish between those who require urgent management of a serious problem such as acute coronary syndrome (ACS) and those with more benign entities who do not require admission. Although clinical judgment continues to be paramount in meeting this challenge, new diagnostic modalities have been developed to assist in risk stratification. These include markers of cardiac injury, risk scores, early stress testing, and noninvasive imaging of the heart. The basic clinical tools of history, physical examination, and electrocardiography are currently widely acknowledged to allow early identification of low-risk patients who have less than 5% probability of ACS. These patients are usually initially managed in the emergency department and transitioned to further outpatient evaluation or chest pain units. Multiple imaging strategies have been investigated to accelerate diagnosis and to provide further risk stratification of patients with no initial evidence of ACS. These include rest myocardial perfusion imaging, rest echocardiography, computed tomographic coronary angiography, and cardiac magnetic resonance imaging. All have very high negative predictive values for excluding ACS and have been successful in reducing unnecessary admissions for patients at low to intermediate risk of ACS. As patients with acute chest pain transition from the evaluation in the emergency department to other outpatient settings, it is important that all clinicians involved in the care of these patients understand the tools used for assessment and risk stratification.

Abstract
BACKGROUND Recurrent chest pain in the absence of coronary artery disease is a common problem that sometimes leads to excess use of medical care. Although many studies examine the causes of pain in these patients, few clinical trials have evaluated treatment. The studies reviewed in this paper provide an insight into the effectiveness of psychological interventions for this group of patients. OBJECTIVES To investigate psychological treatments for non-specific chest pain (NSCP) with normal coronary anatomy. SEARCH STRATEGY We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (2008, Issue 4), MEDLINE (1966 to December 2008), CINAHL (1982 to December 2008) EMBASE (1980 to December 2008), PsycINFO (1887 to December 2008), the Database of Abstracts of Reviews of Effectiveness (DARE) and Biological Abstracts (January 1980 to December 2008). We also searched citation lists and approached authors. SELECTION CRITERIA Randomised controlled trials (RCTs) with standardised outcome methodology that tested any form of psychotherapy for chest pain with normal anatomy. Diagnoses included non-specific chest pain, atypical chest pain, syndrome X, or chest pain with normal coronary anatomy (as either inpatients or outpatients). DATA COLLECTION AND ANALYSIS Two authors independently selected studies for inclusion, extracted data and assessed quality of studies. The authors contacted trial authors for further information about the RCTs included. MAIN RESULTS Ten RCTs (484 participants) were included. There was a significant reduction in reports of chest pain in the first three months following the intervention; fixed effects relative risk = 0.68 (95% CI 0.57 to 0.81). This was maintained from 3 to 9 months afterwards; relative risk = 0.59 (95% CI 0.45 to 0.76). There was also a significant increase in the number of chest pain free days up to three months following the intervention; mean difference = 2.81 (95% CI 1.28 to 4.34). This was associated with reduced chest pain frequency (mean difference = -1.73 (95% CI -2.21 to -1.26)) and severity (mean difference = -6.86 (95% CI -10.74 to -2.97)). However, there was high heterogeneity and caution is required in interpreting these results. Wide variability in outcome measures made integration of studies for secondary outcome measures difficult to report on. AUTHORS' CONCLUSIONS This review suggests a modest to moderate benefit for psychological interventions, particularly those using a cognitive-behavioural framework, which was largely restricted to the first three months after the intervention. Hypnotherapy is also a possible alternative. The evidence for brief interventions was less clear. Further RCTs of psychological interventions for NSCP with follow-up periods of at least 12 months are needed.

Abstract
We investigated body vigilance, cardiac anxiety, and the mediating role of interoceptive fear on pain in patients with non-cardiac chest pain (NCCP; a syndrome of chest pain in the absence of identifiable organic etiology). Patients were more attentive to cardiac-congruent sensations than cardiac-incongruent sensations (e.g., gastrointestinal, cognitive dyscontrol; p's < .001). Patients with a DSM-IV Axis I anxiety or mood disorder were more body vigilant compared to patients who did not have a disorder (p's < .05). Patients with anxiety disorders were particularly vigilant to and fearful of cardiac sensations relative to patients without anxiety disorders. Latent variable path models examined the extent that interoceptive fear mediated the association between body vigilance and cardiac anxiety on chest pain. Within each model, diagnostic status, body vigilance, and cardiac anxiety were exogenous and predicted interoceptive fear that in turn predicted pain. Separate models examined body vigilance and cardiac anxiety, and both models fit the data well. Findings showed partial mediation for the body vigilance factor, and full mediation for the cardiac anxiety factor. Interoceptive fear played a mediating role in both models. The syndrome of NCCP may persist partly due to conscious hypervigilance to and fear of cardiac-congruent body sensations, particularly among anxious patients.

Abstract
Phosphoinositide-dependent kinase (PDK1) plays a central role in signal transduction mediated by phosphatidylinositol 3-kinases (PI3K) and regulates cellular functions in neutrophils. Neutrophils from individuals diagnosed with localized aggressive periodontitis (LAP) present an in vivo phenotype with depressed chemotaxis. The aim of this study was to test the hypothesis that PDK1 regulates chemotaxis in neutrophils and is responsible for the abnormal neutrophil chemotaxis LAP. Neutrophil chemotaxis was significantly suppressed by the PDK1 inhibitor staurosporine. When cells were transfected with PDK1 siRNA, there was a significant reduction in chemotaxis, while superoxide generation was not significantly affected. In primary neutrophils from persons with LAP, PDK1 expression and activation levels were significantly reduced, and this reduction was associated with the reduced phosphorylation of Akt (Thr308) and chemotaxis. Analysis of these data demonstrates that PDK1 is essential for the chemotactic migration of neutrophils, and in the absence of PDK1, neutrophil chemotaxis is impaired.

Abstract
OBJECTIVE To examine the contributions of chest pain, anxiety, and pain catastrophizing to disability in 97 patients with noncardiac chest pain (NCCP) and to test whether chest pain and anxiety were related indirectly to greater disability via pain catastrophizing. METHODS Participants completed daily diaries measuring chest pain for 7 days before completing measures of pain catastrophizing, trait anxiety, and disability. Linear path model analyses examined the contributions of chest pain, trait anxiety, and catastrophizing to physical disability, psychosocial disability, and disability in work, home, and recreational activities. RESULTS Path models accounted for a significant amount of the variability in disability scales (R(2) = 0.35 to 0.52). Chest pain and anxiety accounted for 46% of the variance in pain catastrophizing. Both chest pain (beta = 0.18, Sobel test Z = 2.58, p < .01) and trait anxiety (beta = 0.14, Sobel test Z = 2.11, p < .05) demonstrated significant indirect relationships with physical disability via pain catastrophizing. Chest pain demonstrated a significant indirect relationship with psychosocial disability via pain catastrophizing (beta = 0.12, Sobel test Z = 1.96, p = .05). After controlling for the effects of chest pain and anxiety, pain catastrophizing was no longer related to disability in work, home, and recreational activities. CONCLUSIONS Chest pain and anxiety were directly related to greater disability and indirectly related to physical and psychosocial disability via pain catastrophizing. Efforts to improve functioning in patients with NCCP should consider addressing pain catastrophizing.

Abstract
Since initial reports over 4 decades ago, cases of patients with angina-like chest pain whose coronary angiograms show no evidence of obstructive coronary artery disease and who have no structural heart disease continue to be a common occurrence for cardiologists. Many features of this patient population have remained constant with successive reports over time: a female predominance, onset of symptoms commonly between 40 and 50 years of age, pain that is severe and disabling, and inconsistent responses to conventional anti-ischemic therapy. Because patients may have had abnormal noninvasive testing that led to performance of coronary angiography, investigators have sought to show an association of this syndrome with myocardial ischemia. Abnormalities in coronary flow and metabolic responses to stress have been reported by several groups, findings consistent with a microvascular etiology for ischemia and symptoms, but others have questioned the presence of ischemia, even in patients selected for abnormal noninvasive testing. Despite considerable efforts by many groups over 4 decades, the syndrome remains controversial with regard to pathophysiology, diagnosis, and management.

Abstract
BACKGROUND Patients with ambulatory electrocardiographic (AECG) ST-segment depression and critical coronary narrowing are known to be at increased risk for adverse outcome, but little is known about patients with AECG ST-segment depression without critical coronary narrowing. HYPOTHESIS The objectives of this study were to characterize the coronary angiographic pathology in patients with AECG ST-segment depression but without critical (< 50% diameter stenosis) coronary narrowing and to compare demographic and clinical findings in these patients with those enrolled in the Asymptomatic Cardiac Ischemia Pilot Study with AECG ST-segment depression and critical (> or = 50% diameter stenosis) coronary narrowing. METHODS Coronary angiograms from patients with AECG ST-segment depression were reviewed in a central laboratory and quantitative measurement of percent stenosis was performed. Clinical and angiographic comparisons were made between patients with and without critical coronary narrowing. RESULTS Patients without critical coronary narrowing (n = 64) were younger (p = 0.02), less likely to be male (p < 0.001) or to have risk factors for coronary atherosclerosis or a history of myocardial infarction (p < 0.001), and had fewer ischemic episodes per 24 h on the screening AECG (p = 0.02) than patients with critical coronary narrowing (n = 441). Of patients without critical narrowing, one half had angiographic evidence for coronary artery disease (> or = 20% stenosis) and 60% had an ejection fraction > 70%. CONCLUSIONS Patients with AECG ST-segment depression without critical coronary narrowing are heterogeneous, with half having measurable coronary artery disease. Demographically and clinically, they appear to be different than patients with AECG ST-segment depression with critical coronary narrowing.

Abstract
Treatment of noncardiac chest pain is often difficult because of the heterogeneous nature of the disorder. This condition can stem from gastroesophageal reflux, visceral hyperalgesia, esophageal motility disorders, psychiatric dysfunction, abnormal biomechanical properties of the esophageal wall, sustained esophageal contractions, abnormal cerebral processing of visceral stimulation, or disrupted autonomic activity. For a treatment to be successful, diagnosis of the underlying cause is essential. This article examines three decades of studies from around the world. It concludes that new research into additional mechanisms involved in visceral pain appears promising; but that future studies using improved selective adenosine receptor antagonists and other therapeutic interventions are needed.

Abstract
Cardiophobia, a clinical syndrome that affects hundreds of thousands of individuals in the USA, is characterized by abrupt, recurrent sensations and pain in the chest in the absence of physical pathology. This conceptual article seeks to address the significance of cardiophobia in western culture and to distinguish it from related disorders. In addition, a model of cardiophobia that highlights the role of heart-focused anxiety and interoceptive conditioning in the generation of limited-symptom panic attacks and acute chest pain is presented and vulnerability factors for cardiophobia are discussed. Future research directions relevant to the assessment and treatment of this clinically significant phenomenon are reviewed.

Abstract
Noncardiac chest pain (NCCP) affects approximately 1 quarter of the adult population in the United States. The pathophysiology of the disorder remains to be fully elucidated. Identified underlying mechanisms for esophageal pain include gastroesophageal reflux disease (GERD), esophageal dysmotility, and visceral hypersensitivity. Aggressive antireflux treatment has been the main therapeutic strategy for GERD-related NCCP. NCCP patients with or without spastic esophageal motor disorders are responsive to pain modulators. The value of botulinum toxin injection, endoscopic treatment for GERD, and antireflux surgery in alleviating NCCP symptoms is limited.

Abstract
Background Acute chest pain is a major health problem all over the western world. Active approaches are directed towards diagnosis and treatment of potentially life threatening conditions, especially acute coronary syndrome/ischemic heart disease. However, according to the literature, chest pain may also be due to a variety of extra-cardiac disorders including dysfunction of muscles and joints of the chest wall or the cervical and thoracic part of the spine. The diagnostic approaches and treatment options for this group of patients are scarce and formal clinical studies addressing the effect of various treatments are lacking. Methods/Design We present an ongoing trial on the potential usefulness of chiropractic diagnosis and treatment in patients dismissed from an acute chest pain clinic without a diagnosis of acute coronary syndrome. The aims are to determine the proportion of patients in whom chest pain may be of musculoskeletal rather than cardiac origin and to investigate the decision process of a chiropractor in diagnosing these patients; further, to examine whether chiropractic treatment can reduce pain and improve physical function when compared to advice directed towards promoting self-management, and, finally, to estimate the cost-effectiveness of these procedures. This study will include 300 patients discharged from a university hospital acute chest pain clinic without a diagnosis of acute coronary syndrome or any other obvious cardiac or non-cardiac disease. After completion of the clinic's standard cardiovascular diagnostic procedures, trial patients will be examined according to a standardized protocol including a) a self-report questionnaire; b) a semi-structured interview; c) a general health examination; and d) a specific manual examination of the muscles and joints of the neck, thoracic spine, and thorax in order to determine whether the pain is likely to be of musculoskeletal origin. To describe the patients status with regards to ischemic heart disease, and to compare and indirectly validate the musculoskeletal diagnosis, myocardial perfusion scintigraphy is performed in all patients 2–4 weeks following discharge. Descriptive statistics including parametric and non-parametric methods will be applied in order to compare patients with and without musculoskeletal chest pain in relation to their scintigraphic findings. The decision making process of the chiropractor will be elucidated and reconstructed using the CART method. Out of the 300 patients 120 intended patients with suspected musculoskeletal chest pain will be randomized into one of two groups: a) a course of chiropractic treatment (therapy group) of up to ten treatment sessions focusing on high velocity, low amplitude manipulation of the cervical and thoracic spine, mobilisation, and soft tissue techniques. b) Advice promoting self-management and individual instructions focusing on posture and muscle stretch (advice group). Outcome measures are pain, physical function, overall health, self-perceived treatment effect, and cost-effectiveness. Discussion This study may potentially demonstrate that a chiropractor is able to identify a subset of patients suffering from chest pain predominantly of musculoskeletal origin among patients discharged from an acute chest pain clinic with no apparent cardiac condition. Furthermore knowledge about the benefits of manual treatment of patients with musculoskeletal chest pain will inform clinical decision and policy development in relation to clinical practice.

OBJECTIVE To describe the Funen Neck and Chest Pain (FNCP) study and carry out a comprehensive non-response analysis of the quality of the survey. METHODS The FNCP questionnaire was sent out to 7000 randomly selected individuals aged 20-71 years living in Funen County, Denmark. A full description of the FNCP survey, analysis of selection bias (representativeness of the background population), selective bias (non-responder bias), and item non-response bias was performed by using Danish vital statistics. RESULTS The adjusted response rate was 60%. Men, retired individuals, and individuals with lower income tended to be late responders. Women, people aged 50+, married individuals, and individuals with two or three children, with a higher educational level, living in a single house or with a high income were more likely to participate. Conversely, men, younger individuals, singles or divorced persons, individuals living in residential caring homes, and with lower educational level were less likely to participate. Adjustments based on design and logical omissions gave an overall missing data rate of 1.0%. In general, the frequency of missing data increased with age and was higher for women. The frequency of inconsistent answers was 0.34%. CONCLUSIONS A comprehensive non-response analysis showed some sociodemographic discrepancies between the FNCP study and the background population. The pattern of missing data was strongly associated with the design of the questionnaire and with participants' willingness to answer only questions they considered relevant. These factors must be taken into consideration when results from the FNCP study are presented.

Abstract
BACKGROUND/AIM The treatment of esophageal (noncardiac) chest pain is unsatisfactory and there is no approved therapy. A previous uncontrolled study suggested that theophylline may be useful. Our aims were to investigate the effects of theophylline on esophageal sensorimotor function and chest pain. METHODS In a double-blind study, sensory and biomechanical properties of the esophagus were assessed using impedance planimetry in 16 patients with esophageal hypersensitivity, after intravenous theophylline or placebo. In a second, randomized 4-wk crossover study, oral theophylline and placebo were administered to 24 patients with esophageal hypersensitivity. Frequency, intensity, and duration of chest pain episodes were evaluated. RESULTS After IV theophylline, chest pain thresholds (P=0.027) and esophageal cross-sectional area (P=0.03) increased and the esophageal wall became more distensible (P=0.04) compared with placebo. After oral theophylline, the number of painful days (P=0.03) and chest pain episodes (P=0.025), pain duration (P=0.002), and its severity (P=0.031) decreased. Overall symptoms improved in 58% on theophylline and 6% on placebo (P<0.02). There was no order effect. CONCLUSIONS Theophylline relaxed the esophageal wall, decreased hypersensitivity, and improved chest pain. Theophylline is effective in the treatment of functional chest pain.

Abstract
OBJECTIVE To assess the long-term effect of spinal cord stimulation (SCS) in patients with refractory cardiac syndrome X (CSX). METHODS A prospective, controlled, long-term follow-up was performed of 19 patients with CSX with refractory angina who underwent SCS (SCS group, 5 men, mean (SD) age 60.9 (8.5) years); 9 comparable patients with CSX who refused SCS treatment (3 men, mean (SD) age 60.9 (8.8) years) constituted the control group. Clinical and functional status were assessed at the time of screening for SCS indication (basal evaluation) and at a median (range) follow-up of 36 (15-82) months. RESULTS The two groups at baseline did not show any difference in clinical characteristics and angina status. All indicators of angina status (angina episode frequency, duration and short-acting nitrate use) improved significantly at follow-up in the SCS group (p<0.001) but not in controls. Functional status, as assessed by the Seattle Angina Questionnaire and a visual analogue scale for quality of life, improved at follow-up in the SCS group (p<0.001 for all scales) but not in controls. Exercise tolerance, exercise-induced angina and ST segment changes also significantly improved in the SCS group but not in controls. CONCLUSIONS Data show that SCS can be a valid form of treatment for long-term control of angina episodes in patients with refractory CSX.

Abstract
BACKGROUND Women are more likely than men to have nonspecific chest pain (NSCP) symptoms. The long-term outcomes in women discharged with a diagnosis of NSCP are unknown. METHODS The Women's Health Initiative Observational Study enrolled postmenopausal women aged 50-79 years. After excluding those with prior cardiovascular disease (CVD), 83,622 women were studied. NSCP cases were defined as having an initial primary hospital discharge diagnosis of NSCP (ICD-9 codes 786.50, 786.51, 786.59) without a prior diagnosis of coronary heart disease (CHD). Risks of subsequent CHD events were estimated from Cox proportional hazard ratio (HR) models stratified by clinic and adjusted for baseline age, cardiovascular risk factors, and hormone use. RESULTS Over an average of 8 years of follow-up, 11% (230 of 2,092) of women with NSCP experienced a cardiovascular event compared with 9.5% (7,724 of 81,530) who did not. Compared with women without a hospitalization for NSCP during follow-up, those with NSCP had a greater than 2-fold higher risk of a subsequent hospitalization for clinically diagnosed angina (HR 2.18, 95% CI 1.66-2.86) and at least a 1.5-fold higher risk of nonfatal myocardial infarction (MI) (HR 1.59, 1.10-2.31), revascularization (HR 1.67, 1.28-2.20), and congestive heart failure (HR 1.75, 1.27-2.41). Women with NSCP who subsequently experienced a CHD event were more likely to be over age 65 or to have cardiovascular risk factors. CONCLUSIONS Older women discharged with a diagnosis of NSCP may be at increased risk of CHD morbidity. Further research is needed to replicate these findings in other populations.

Abstract
OBJECTIVE The aims of this study were to (a) study the persistence of panic disorder (PD); (b) investigate the association between PD at baseline and outcome [chest pain, psychiatric morbidity, health care utilization, suicidal thoughts, work impairment and health-related quality of life (HRQOL)]; (c) study the course of pain, distress, symptom attribution and HRQOL; and (d) describe treatment and perceived treatment needs of patients with PD. METHOD A 1-year follow-up study of 199 chest-pain patients referred to cardiac outpatient investigation was completed. Assessments included Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (SCID), Short-Form McGill Pain Questionnaire, Symptom Checklist-90-Revised, the Illness Attitude Scales, the 36-item Short-Form Health Survey and a chest-pain questionnaire. RESULTS At follow-up, 57 of the 153 patients reassessed with the SCID suffered from PD. Forty-three of the 55 patients (78%) who were diagnosed with PD at baseline still suffered from PD at follow-up. PD at baseline was associated with pain persistence, psychiatric morbidity (current major depression, pain disorder and simple phobia), significantly higher scores on psychological distress, hypochondriasis, negative outcome expectation, lower scores on seven of the eight dimensions of HRQOL and more general practitioner consultations. Only 6% of the patients with PD used effective treatment, and 3% reported a treatment need at follow-up. CONCLUSION Despite chronic distress and impairment, we found significant undertreatment of PD, which needs to be addressed in future studies.

Abstract
BACKGROUND Chest pain is a common symptom that presents the primary care physician with a complex diagnostic and therapeutic challenge. AIMS To evaluate the natural history and management of patients diagnosed with chest pain of unspecified type or origin in primary care. DESIGN Population-based case-control study. METHODS The study included 13,740 patients with a first diagnosis of unspecified chest pain and 20,000 age- and sex-matched controls identified from the UK General Practice Research Database. Odds ratios (ORs) and 95% confidence intervals (CIs) were computed using unconditional logistic regression. Risk estimates were adjusted for age, sex and number of physician visits. RESULTS The incidence of a new diagnosis of chest pain was 15.5 per 1000 person-years and increased with age, particularly in men. The risk of a chest pain diagnosis was greatest in patients with prior diagnoses of coronary heart disease (OR: 7.1; 95% CI: 6.1-8.2) and gastroesophageal reflux disease (OR: 2.0; 95% CI: 1.7-2.3). In the year after diagnosis, chest pain patients were more likely than controls to be newly diagnosed with coronary heart disease (OR: 14.9; 95% CI: 12.7-17.4) and heart failure (OR: 4.7; 95% CI: 3.6-6.1). A new diagnosis of chest pain was associated with an increased risk of death in the following year (RR: 2.3; 95% CI: 1.9-2.8). CONCLUSIONS Some causes of chest pain are underdiagnosed in primary care. This is of particular consequence for the minority of chest pain patients with cardiac disease.

Abstract
Management of patients with coronary artery disease is a major challenge for physicians, patients, and the healthcare system. Chest pain experienced by patients with coronary disease can be of noncardiac origin, and symptoms frequently related to gastroesophageal etiologies. The distal esophagus and the heart share a common afferent nerve supply, suggesting that location and radiation of perceived pain may be identical. In addition, there is substantial overlap between the prevalence of coronary disease and gastroesophageal reflux disease. Many physicians, including cardiologists, prescribe acid-reducing therapy to coronary patients. However, no prospective, randomized studies to date have evaluated the potential benefit of such treatments to prevent chest pain symptoms for these patients. We review the studies on noncardiac chest pain demonstrating reflux in patients with and without coronary disease. Also, the association of reflux with exertional chest pain and cardiac syndrome X is discussed. A rationale is presented for prevention of noncardiac chest pain in coronary patients, and the potential role of acid-suppressive therapy in managing these patients is discussed.

Abstract
BACKGROUND Gastro-oesophageal reflux disease (GORD) is a chronic condition affecting up to one-quarter of the Western population. GORD is characterized by heartburn and acid regurgitation, but is reported to be associated with a spectrum of extra-oesophageal symptoms. OBJECTIVE The aim of this systematic review was to critically evaluate postulated extra-oesophageal symptoms of GORD. METHODS Extra-oesophageal symptoms were identified from population-based studies evaluating their association with GORD (either defined as heartburn and/or acid regurgitation, or diagnosed in general practice). The response of these symptoms to acid-suppressive therapy was investigated using randomized, double-blind, placebo-controlled studies. Pathogenic mechanisms were evaluated using clinical and preclinical studies. RESULTS An association between GORD and symptoms or a diagnosis of chest pain/angina, cough, sinusitis and gall-bladder disease was evident from three eligible population-based studies of GORD. Randomized placebo-controlled studies (n=20) showed that acid-suppressive therapy provides symptomatic relief of chest pain, asthma and, potentially, chronic cough and laryngitis. Mechanistic models, based on direct physical damage by refluxate or vagally mediated reflexes, support a causal role for GORD in chest pain and respiratory symptoms, but not in gall-bladder disease. CONCLUSION GORD is likely to play a causal role in chest pain and possibly asthma, chronic cough and laryngitis. Further investigation is desirable, particularly for other potential extra-oesophageal manifestations of GORD such as chronic obstructive pulmonary disease, sinusitis, bronchitis and otitis. Acid-suppressive therapy is likely to benefit patients with non-cardiac chest pain, but further placebo-controlled studies are needed for other symptoms comprising the extra-oesophageal spectrum of GORD.
