Five-year follow-up of young adults visiting an emergency unit because of atypical chest pain

A closer look at the relationships between panic attacks, emergency department visits and non-cardiac chest pain

This study examined the prevalence of emergency department visits prompted by panic attacks in patients with non-cardiac chest pain. A validated structured telephone interview was used to assess panic attacks and their association with the emergency department consultation in 1327 emergency department patients with non-cardiac chest pain. Patients reported at least one panic attack in the past 6 months in 34.5 per cent (95% confidence interval: 32.0%–37.1%) of cases, and 77.1 per cent (95% confidence interval: 73.0%–80.7%) of patients who reported panic attacks had visited the emergency department with non-cardiac chest pain following a panic attack. These results indicate that panic attacks may explain a significant proportion of emergency department visits for non-cardiac chest pain.

Unexplained acute chest pain in young adults: disease patterns and medication use 25 years later

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.

A prospective cohort study to refine and validate the Panic Screening Score for identifying panic attacks associated with unexplained chest pain in the emergency department

INTRODUCTION

Panic-like anxiety (panic attacks with or without panic disorder), a highly treatable condition, is the most prevalent condition associated with unexplained chest pain in the emergency department. Panic-like anxiety may be responsible for a significant portion of the negative consequences of unexplained chest pain, such as functional limitations and chronicity. However, more than 92% of panic-like anxiety cases remain undiagnosed at the time of discharge from the emergency department. The 4-item Panic Screening Score (PSS) questionnaire was derived in order to increase the identification of panic-like anxiety in emergency department patients with unexplained chest pain.

METHODS AND ANALYSIS

The goals of this prospective cohort study were to (1) refine the PSS; (2) validate the revised version of the PSS; (3) measure the reliability of the revised version of the PSS and (4) assess the acceptability of the instrument among emergency physicians. Eligible and consenting patients will be administered the PSS in a large emergency department. Patients will be contacted by phone for administration of the criterion standard for panic attacks as well as by a standardised interview to collect information for other predictors of panic attacks. Multivariate analysis will be used to refine the PSS. The new version will be prospectively validated in an independent sample and inter-rater agreement will be assessed in 10% of cases. The screening instrument acceptability will be assessed with the Ottawa Acceptability of Decision Rules Instrument.

ETHICS AND DISSEMINATION

This study protocol has been reviewed and approved by the Alphonse-Desjardins research ethics committee. The results of the study will be presented in scientific conferences and published in peer-reviewed scientific journals. Further dissemination via workshops and a dedicated website is planned.

A 14-year follow-up study of chest pain patients including stress hormones and mental stress at index event

BACKGROUND

Knowledge of long-term outcome in chest pain patients is limited. We reinvestigated patients who 14 years earlier had visited the emergency department due to chest pain, and were discharged without hospitalization. Extensive examinations were made at that time on 484 patients including full medical history, exercise test, a battery of stress questions and stress hormone sampling.

METHODS

From a previously conducted chest pain study patients still alive after 14 years were approached. Hospitalization or deaths with a diagnosis of ischemic heart disease or cerebrovascular disease were used as end point.

RESULTS

During the follow-up period 24 patients had died with a diagnosis of ischemic heart or cerebrovascular disease, and 50 patients had been given such a diagnosis at hospital discharge. Age (OR 1.12, CI 1.06-1.19), previous history of angina pectoris (OR 9.69, CI 2.06-71.61), pathological ECG at emergency department visit (OR 3.27, CI 1.23-8.67), hypertension (OR 5.03, CI 1.90-13.76), smoking (OR 3.04, CI 1.26-7.63) and lipid lowering medication (OR 14.9, CI 1.60-152.77) were all associated with future ischemic heart or cerebrovascular events. Noradrenalin levels were higher in the event group than in the non-event group, mean (SD) 2.44 (1.02) nmol/L versus 1.90 (0.75) nmol/L. When noradrenalin was included in the regression model high maximal exercise capacity was protective of an event (OR 0.986, CI 0.975-0.997).

CONCLUSION

In chest pain patients previous history of angina pectoris, hypertension, smoking, pathological ECG at primary examination, and age were the main risk factors associated with future cardiovascular or cerebrovascular events.

Unexplained chest pain in the ED: could it be panic?

PURPOSE

This study aimed at (1) establishing the prevalence of paniclike anxiety in emergency department (ED) patients with unexplained chest pain (UCP); (2) describing and comparing the sociodemographic, medical, and psychiatric characteristics of UCP patients with and without paniclike anxiety; and (3) measuring the rate of identification of panic in this population.

BASIC PROCEDURE

A structured interview, the Anxiety Disorders Interview Schedule for the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, was administered to identify paniclike anxiety and evaluate patients' psychiatric status. Anxious and depressive symptoms were evaluated with self-report questionnaires. Medical information was extracted from patients' medical records.

MAIN FINDINGS

The prevalence of paniclike anxiety was 44% (95% CI, 40%-48%) in the sample (n = 771). Psychiatric disorders were more common in panic patients (63.4% vs 20.1%), as were suicidal thoughts (21.3% vs 11.3%). Emergency physician diagnosed only 7.4% of panic cases.

PRINCIPAL CONCLUSIONS

Paniclike anxiety is common in ED patients with UCP, and this condition is rarely diagnosed in this population.

Pain catastrophizing in patients with noncardiac chest pain: relationships with pain, anxiety, and disability

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.

Effect on quality of life of different accelerated diagnostic protocols for management of patients presenting to the emergency department with acute chest pain

This study assessed the effects on quality of life (QoL) of dobutamine-atropine stress echocardiography (DASE) and electrocardiogram exercise testing (EET) accelerated diagnostic protocols for early stratification of low-risk patients with acute chest pain (ACP). A total of 290 patients with ACP, a nondiagnostic electrocardiogram, and negative biomarkers were randomly assigned to an accelerated diagnostic protocol (DASE, n = 110, or EET, n = 89) or usual care (n = 91) and followed up for 2 months. QoL was assessed at discharge and 2-month follow-up using the Nottingham Health Profile questionnaire. Baseline and 2-month follow-up answers to the Nottingham Health Profile questionnaire were available for 207 patients (71%; 55 in the usual-care, 77 in the DASE, and 75 in the ETT arm). At predischarge, patients in the usual-care arm reported higher impairment in the physical mobility and pain dimensions compared with the DASE and EET arms (p = 0.019 and p = 0.023, respectively). At 2-month follow-up, QoL improved in all groups; however, patients in the usual-care arm had significantly worse scores than patients managed using accelerated diagnostic protocols in the physical mobility, pain, social isolation, emotional reactions, and energy level dimensions (p = 0.014, p = 0.002, p = 0.04, p = 0.01, and p = 0.003, respectively). In conclusion, low-risk patients with ACP had non-negligible impairment of QoL in the acute phase. Emergency department ADPs with early DASE and EET reduced QoL impairment at both baseline and 2-month follow-up.

Natural history and predictors of outcome for non-cardiac chest pain: a prospective 4-year cohort study

The natural history of non-cardiac chest pain (NCCP) is poorly understood. We aimed to assess the 2- and 4-year outcomes of patients with chest pain, and determine whether baseline characteristics could predict outcomes (mortality, continued chest pain and quality of life). This was a prospective cohort study in a tertiary teaching hospital (Nepean Hospital), Sydney, Australia. All subjects who presented with acute chest pain to the emergency department were recruited at baseline (n = 197). Mortality data were obtained from death certificates on the entire cohort at 4 years; 129 (65%) patients responded to a 2 year follow-up and 92 (47%) to a 4-year follow-up questionnaire. At baseline, there were 126 (60%) NCCP patients and 71 cardiac patients. Chest pain continued to be reported in the majority of individuals (>65%) at follow-up. Over the 2-year period, NCCP disappeared among 10% (n = 9/88), but remained present in the remaining 90% (n = 79). In comparison, 69% (n = 28/41) of the cardiac chest pain (CCP) patients continued to have chest pain at the 2-year follow-up (NCCP vs CCP: P < 0.001). At the 4-year follow-up, 71% (n = 45/64) and 81% (23/27) continued to have NCCP and CCP respectively. The mortality rate among the entire cohort over the 4-year study was 9% (17/197). The cardiac mortality rate for patients initially diagnosed with CCP was 11% (8/71); compared with 5.5% (7/126) (P = 0.16) among patients initially diagnosed with NCCP who subsequently died from a cardiac cause. Outcomes in terms of mortality did not significantly differ between cardiac and NCCP patients. Both groups experienced continued chest pain during the follow-up period. Non-cardiac chest pain does not always confer an excellent long-term prognosis.

Anxiety disorder in patients with non-specific chest pain in the emergency setting

OBJECTIVES

Many patients who have been discharged from the emergency department (ED) with a diagnosis of "non-specific chest pain" (NSCP) have anxiety disorder (AD), a commonly missed entity in acute care. The objective of this study was to delineate characteristic properties that could enhance recognition of AD in ED patients admitted with NSCP.

METHODS

All patients between 18 and 65 years of age diagnosed with NSCP were enrolled. The Hospital Anxiety and Depression Scale (HADS) anxiety subscale was used as a screening test for AD. The patients with high HADS scores (> or = 10) were evaluated by a psychiatrist for AD.

RESULTS

In total, 157 patients were enrolled in the study. HADS scores were found to be "high" (> or = 10) in 49 patients (31.2%). Patients with high HADS scores had a higher frequency of associated symptoms (p = 0.004). Dizziness or lightheadedness, chills or hot flushes, and fear of dying were found to have been reported more frequently by patients with high anxiety scores. Of the group with high score, 33 patients (67.3%) were interviewed by a psychiatrist, and 23 (69.7%) of these patients were diagnosed with AD. Associated symptoms were described by 21 patients with AD (91.3%). Of those with AD, 18 (78.3%) had been previously admitted to the ED with chest pain. Atypical chest pain was described by 21 patients (91.3%).

CONCLUSIONS

Physicians should always consider AD in patients presenting to the ED with chest pain after ruling out organic aetiology. Patients' definition of atypical pain, recurrent admissions to ED, and presence of associated symptoms such as dizziness, chills or hot flushes, and fear of dying could aid in considering AD.

How do we define non-cardiac chest pain?

Noncardiac chest pain (NCCP) is a heterogeneous disorder associated with substantial health-care costs and resource utilization. NCCP is defined by recurrent episodes of substernal chest pain in patients lacking a cardiac cause after a comprehensive evaluation. The magnitude of the problem is quite high because of fear of serious or life-threatening heart diseases. Patients with chest pain who present for the first time to ambulatory care or to the emergency room, only 11% to 39% are ultimately diagnosed with coronary artery disease. The likely causes of NCCP are numerous and often overlap. Diagnosing NCCP is difficult because NCCP remains a diagnosis of exclusion that encompasses heterogeneous patient populations. First, cardiac ischemic must be excluded and coronary angiography remains the gold standard. Once cardiac causes have been ruled out, a diagnosis of NCCP is made. Mostly, the source for NCCP originates in essence from the esophagus. Gastroesophageal reflux disease (GERD) is the most common esophageal diseases present in patients with NCCP. An initial empiric trail of high-dose acid suppression is the most cost-effective measure in the management of these patients. When a diagnostic workup is chosen, it centers on upper gastrointestinal endoscopy, 24-hr esophageal pH monitoring and esophageal manometry.

A randomised controlled trial to measure the effect of chest pain unit care upon anxiety, depression, and health-related quality of life [ISRCTN85078221]

BACKGROUND

The chest pain unit (CPU) has been developed to provide a rapid and accurate diagnostic assessment for patients attending hospital with acute, undifferentiated chest pain. We aimed to measure the effect of CPU assessment upon psychological symptoms and health-related quality of life.

METHODS

We undertook a single-centre, cluster-randomised controlled trial. Days (N = 442) were randomised in equal numbers to CPU or routine care. Patients with acute chest pain, undiagnosed by clinical assessment, ECG and chest radiograph, were recruited and followed up with self-completed questionnaires (SF-36 and HADS) at two days and one month after hospital attendance.

RESULTS

Patients receiving CPU assessment had significantly higher scores on the physical functioning (difference 5.1 points; 95% CI 1.1 to 9.0), vitality (4.6; 1.3 to 8.0), and general health (5.7; 2.3 to 9.2) dimensions of the SF-36 at two days, and significantly higher scores on all except the emotional role dimension at one month. They also had significantly lower depression scores on the HADS depression scale at two days (0.93; 0.34 to 1.51) and one month (1.0; 0.36 to 1.66). However, initially lower anxiety scores at two days (0.89; 0.21 to 1.56) were not maintained at one month (0.48; -0.26 to 1.23). CPU assessment was associated with reduced prevalence (OR 0.71; 95% CI 0.52 to 0.97) and severity (6.5 mm on 100 m visual analogue scale; 95% CI 2.2 to 10.8) of chest pain at one month, but no significant difference in the proportion of patients taking time off work (OR 0.82; 95% CI 0.54 to 1.04).

CONCLUSION

CPU assessment is associated with improvements in nearly all dimensions of quality of life and with reduced symptoms of depression.

Noncardiac chest pain: epidemiology, natural history, health care seeking, and quality of life

The epidemiology of NCCP is poorly described, and the available data are conflicting. Population-based studies on the prevalence of NCCP are rare; most studies have been hospital based. According to the limited studies available, the annual prevalence of NCCP is approximately 25%. Despite this significant burden, the impact and natural history of NCCP in the community has not been adequately explored. NCCP is presumed to bea heterogeneous condition. Hospital-based studies have suggested that GERD, esophageal spasm, psychiatric disease (including panic attacks), and musculoskeletal pain explain many cases of NCCP. However, unrecognized coronary artery disease and microvascular angina (cardiac syndrome X)also explain an unknown proportion of cases in the general population.Current studies suggest that NCCP is common in the general population and significantly affects QOL, yet only a minority seeks medical attention.The epidemiology of NCCP requires further study in the general population and in those attending the Emergency Department.

Non-cardiac chest pain: prevalence, risk factors, impact and consulting--a population-based study

BACKGROUND

Little is known about the prevalence and importance of non-cardiac chest pain in the general population.

AIM

To evaluate the magnitude and impact of this condition.

METHODS

A validated self-report questionnaire was mailed to a sample of 1000 residents of Penrith, selected randomly from the electoral rolls. Symptoms, risk factors, psychological distress, quality of life and demographics were measured.

RESULTS

The response rate was 73% (n = 672; mean age, 46 years; 52% female). Chest pain ever was reported by 39% of the population; 7% reported a history of myocardial infarction and 8% a history of angina. Two hundred and nineteen (33%) cases were classified as non-cardiac chest pain; only 23% had consulted a physician about chest pain in the previous year. The only independent risk factor for non-cardiac chest pain was the frequency of heartburn (odds ratio, 1.74; 95% confidence interval, 1.08-2.79; P = 0.02). None of the gastrointestinal (heartburn, dysphagia, acid regurgitation) or psychological (anxiety, depression, neuroticism) risk factors were significantly associated with consulting for non-cardiac chest pain.

CONCLUSIONS

Non-cardiac chest pain is remarkably common in the general population and negatively impacts on the quality of life. Gastro-oesophageal reflux disease is a key risk factor for non-cardiac chest pain in the community. Health care seeking for non-cardiac chest pain remains unexplained.

Treatment needs of patients admitted for acute chest pain

OBJECTIVE

To examine the characteristics, subsequent resource use and outcome of a consecutive cohort of admissions with acute chest pain not due to myocardial infarction.

METHODS

Subjects (N=356) identified in the course of a epidemiological study of myocardial infarction were interviewed and completed HAD, SF-36 and other self-report information in hospital and at 3 months and 1 year. Hospital casenotes were reviewed at 1 year.

RESULTS

A total of 218 subjects were given cardiac diagnoses and 138 noncardiac diagnoses. Cardiac subjects were more distressed and disabled and used more resources. Those in the noncardiac group reported distress and disability and resource use comparable to infarct admissions.

CONCLUSION

Awareness of psychosocial variables would aid in the assessment and management of those with and without ischaemic heart disease.

Review article: the burden of illness of non-cardiac chest pain

BACKGROUND

Non-cardiac chest pain is a common condition affecting approximately one-quarter of the population during their lifetime, but the long-term economic costs of non-cardiac chest pain are poorly defined.

METHODS

A MEDLINE and Current Contents search was performed from 1991 to 2002 using specific keywords. All major articles on the subject of non-cardiac chest pain in this period were reviewed and their reference lists searched.

RESULTS

Limited studies suggest that the majority of those with non-cardiac chest pain do not consult a doctor regarding their symptoms; the drivers of health care seeking are not known. The impact on the quality of life in consulters can be severe, with as many as 36% reporting much lower quality of life levels. The diagnosis of non-cardiac chest pain can be difficult due to the heterogeneous nature of the condition, with significant overlap of gastro-oesophageal reflux disease, chest wall syndromes and psychiatric disease, which may drive up the costs of management. The prognosis appears to be good, but there are conflicting results in long-term studies.

CONCLUSIONS

The costs of non-cardiac chest pain to the health care system are likely to be large and represent a significant proportion of each Western country's health care budget. Further studies are required to determine methods of reducing health care costs.

Psychologic morbidity and health-related quality of life of patients assessed in a chest pain observation unit

STUDY OBJECTIVES

We sought to measure psychologic morbidity and health-related quality of life among patients attending the hospital with acute chest pain both at presentation and 1 month after rigorous assessment for cardiac disease.

METHODS

Consecutive patients undergoing assessment on the chest pain observation unit of a large, urban emergency department were asked to complete 3 questionnaires: the Short Form-36 Health Survey (SF-36), the Euroqol Health Utility Questionnaire, and the Hospital Anxiety and Depression Scale. The same questionnaires were mailed 1 month later, along with a questionnaire documenting subsequent pain and reassurance.

RESULTS

At enrollment (n=166), 32 (19%) participants (95% confidence interval [CI] 15% to 26%) were experiencing moderate levels of anxiety, and 21 (13%, 95% CI 8% to 19%) were experiencing moderate levels of depression. Health utility and all SF-36 dimensions of quality of life were substantially below age-adjusted normal values. One month after assessment (n=110), only the Pain dimension score of SF-36 had significantly improved. Most scores were unchanged, and the Physical Role and Mental Health dimension scores of SF-36 had significantly deteriorated. Seventy (64%) patients (95% CI 54% to 72%) had further pain after discharge. Despite these findings, 98 (86%) patients (95% CI 78% to 91%) responded that their assessment was "completely reassuring" or "quite reassuring."

CONCLUSION

Patients with acute, undifferentiated chest pain have substantial psychologic morbidity and impairment of quality of life. Although patients respond that they are reassured by chest pain observation unit assessment, anxiety and depression remain prevalent and quality of life remains impaired 1 month after assessment.

Depression and anxiety as predictors of outcome after myocardial infarction

OBJECTIVE

The objective of this study was to investigate the significance of emotional distress immediately after a myocardial infarction as a predictor of physical, psychological, and social outcomes and resource use.

METHODS

In an epidemiological survey, demographic and cardiological data were obtained for all patients from a defined geographical area who had had a myocardial infarction (according to diagnostic criteria of the Monitoring Trends and Determinants in Cardiovascular Disease [MONICA] trial). Hospital survivors were interviewed and were asked to complete self-report assessments on mental state and quality of life. Full replies were available at baseline for 347 subjects. Self-report follow-up questionnaire information was collected 3 months and 1 year later.

RESULTS

Fifteen percent of patients scored as probable cases of anxiety or depression. They were more likely than noncases to report preinfarct distress and poor adjustment (as indicated on the 36-item Medical Outcome Study short form). There was an improvement at 3 months, but there was little overall or individual change after that time. Anxiety and depression did not predict subsequent mortality but did significantly predict poor outcome at 1 year on all dimensions of the 36-item short form quality-of-life measure and on specific measures of everyday activity and reports of chest pain, use of primary care resources, and secondary prevention lifestyle changes.

CONCLUSIONS

Subjects who are distressed in the hospital are at high risk of adverse psychological and quality-of-life outcomes during the ensuing year. Our findings strengthen the argument for in-hospital identification and treatment of patients with depression and anxiety after myocardial infarction.

Presentation, management and course of angina and suspected angina in primary care

Previous surveys may have underestimated both prevalence and incidence of ischemic heart disease in general practice. Case identification is difficult, as many patients presenting with chest pain turn out not to have ischemic heart disease, although their outcome is unclear otherwise. In this work we aimed to: (1) estimate prevalence and incidence of angina in one Oxford general practice; (2) describe the processes of assessment, investigation, and management of suspected angina; and (3) describe the 2-year symptomatic and functional outcome of angina patients, compared with patients whose provisional diagnosis of suspected ischemic heart disease (IHD) was not subsequently sustained (NCCP). A retrospective survey of patients was undertaken (aged 45-74 years) by hand searching paper and electronic medical records to find, as of 1 January 1992, all patients in the practice with continuing treatment of angina diagnosed before 1989, or those having a new diagnosis of angina being assessed (suspected angina) in the 3 year 1989-1991. Two years later, a postal questionnaire survey compared the symptomatic and functional outcome of confirmed IHD and NCCP. On 1 January 1992, the diagnosis of angina was recorded in the notes of 11.1% of patients aged 45-74 years, and the diagnosis was considered correct in 7.4%. Over a 3-year period, 129 people was suspected of suffering from angina, but in 71 (55%) the diagnosis was not confirmed; 76 (59%) were either referred to a specialist out-patient clinic or had an emergency admission. A 2-year follow-up found that similar proportions of patients with angina and noncardiac chest pain had a poor outcome in terms of symptoms, mental state, quality of everyday life, and continuing consultation. The clinical burden of ischemic heart disease in general practice has been underestimated by earlier methodological approaches using less complete ascertainment strategies. The adequacy of current diagnostic and management arrangements for patients with suspected angina merits review, at both the primary and secondary care levels.

Noncardiac chest pain: interest in a medical psychological treatment

The aim of this study was to assess to what extent patients with unexplained chest pain (UCP) are interested in a medical psychological treatment, and to find biographical or medical status variables predictive of that need. A total of 1053 patients with a discharge diagnosis of UCP from two cardiac outpatient clinics were approached by mail. Of these, 77.2% returned the questionnaire, which inquired about duration, frequency, and intensity of UCP; limitations in activities; and whether they would like medical psychological treatment for their UCP. Results showed little spontaneous recovery, and indicated no association between duration of UCP and interest in treatment. Younger patients and males were more interested in treatment. Furthermore, limitations in activities rather than frequency or intensity of pain was the most important predictor of interest in treatment. A three-step plan is proposed to enhance care for patients with UCP.

Neurocirculatory asthenia: a reassessment using modern psychosomatic criteria

The purpose of this study was to assess the prevalence of mental illness and to evaluate the quality of life of patients with neurocirculatory asthenia. A consecutive series of 80 patients who satisfied the diagnostic criteria developed by Kannel et al. for neurocirculatory asthenia was included in this study. Patients underwent a psychiatric diagnostic research interview and extensive psychometric evaluation, with both observer and self-rated scales for depression, anxiety, phobic symptoms, quality of life and abnormal illness behavior. In 47 patients (59%), a psychiatric diagnosis (mainly an anxiety disorder) antedated the onset of neurocirculatory asthenia, which was thus defined as secondary, also because cardiorespiratory symptoms were part of the mental symptoms. In the remaining 33 patients (41%) neurocirculatory asthenia was the primary disorder. Patients with secondary neurocirculatory asthenia reported significantly higher levels of anxiety, depression, social phobia, abnormal illness behavior and an impaired quality of life compared with patients with primary neurocirculatory asthenia. This latter did not significantly differ in these variables (except for depression) from healthy control subjects matched for sociodemographic variables. At a 1-year follow-up, patients with primary neurocirculatory asthenia had a much better prognosis than those with secondary neurocirculatory asthenia. The results indicate the feasibility of the primary/secondary distinction based on the time of onset of mental and cardiorespiratory symptoms in neurocirculatory asthenia. Since only about one quarter of the patients were found to suffer from decreased energy and fatigue according to specified criteria, the terms neurocirculatory asthenia and effort syndrome should probably be discarded.
