Cognitive-perceptual factors in noncardiac chest pain and cardiac chest pain

Biobehavioral approach to distinguishing panic symptoms from medical illness

Panic disorder is a common psychiatric diagnosis characterized by acute, distressing somatic symptoms that mimic medically-relevant symptoms. As a result, individuals with panic disorder overutilize personal and healthcare resources in an attempt to diagnose and treat physical symptoms that are often medically benign. A biobehavioral perspective on these symptoms is needed that integrates psychological and medical knowledge to avoid costly treatments and prolonged suffering. This narrative review examines six common somatic symptoms of panic attacks (non-cardiac chest pain, palpitations, dyspnea, dizziness, abdominal distress, and paresthesia), identified in the literature as the most severe, prevalent, or critical for differential diagnosis in somatic illness, including long COVID. We review somatic illnesses that are commonly comorbid or produce panic-like symptoms, their relevant risk factors, characteristics that assist in distinguishing them from panic, and treatment approaches that are typical for these conditions. Additionally, this review discusses key factors, including cultural considerations, to assist healthcare professionals in differentiating benign from medically relevant symptoms in panic sufferers.

Determinants of depression in non-cardiac chest pain patients: a cross sectional study

BACKGROUND

Non-cardiac chest pain (NCCP) is a common patient complaint imposing great costs on the healthcare system. It is associated with psychological factors such as depression. The aim of the present study is determining depression predictors in NCCP patients.

METHODS

The participants of this cross-sectional study were 361 NCCP patients. Patients filled out questionnaires concerning their sociodemographic, lifestyle, and clinical factors (severity of pain, type D personality, somatization, cardiac anxiety, fear of body sensations, and depression).

RESULTS

Based on multiple ordinal logistic regression, lack of physical activity (odds ratio [OR], 1.78; 95% confidence interval [CI], 1.09-2.87), sleep quality (OR, 2.98; 95% CI, 1.15-7.69), being a smoker (OR, 1.33; 95% CI, 2.41-4.03), present pain intensity (OR, 1.08; 95% CI, 1.05-1.11), type D personality (OR, 2.43; 95% CI, 1.47- 4.03), and somatization (OR, 1.22; 95% CI, 1.15-1.3) were significant predictors of depression in NCCP patients. Additionally, multiple linear regression showed that being unmarried (β = 1.51, P = 0.008), lack of physical activity (β = 1.22, P = 0.015), sleep quality (β = 2.26, P = 0.022), present pain intensity (β = 0.07, P = 0.045), type D personality (β = 1.87, P < 0.001), somatization (β = 0.45, P < 0.001), and fear of bodily sensation (β = 0.04, P = 0.032) increased significantly depression scores in NCCP patients.

CONCLUSIONS

Physicians should consider the predictors of depression in NCCP patients which can lead to receiving effective psychological consultations and reducing the costs and ineffectual referrals to medical centers.

Investigating Attachment Insecurity and Somatosensory Amplification, and the Mediating Role of Interpersonal Problems

Abstract. Background: Somatosensory amplification involves perceptual sensitivity to and cognitive-affective interpretation of bodily sensations and external stimuli, contributing to heightened experiences of somatic symptoms. However, little is known about somatosensory amplification in relation to vulnerabilities such as attachment insecurity. Aims: The present study investigated the link between attachment insecurity and somatosensory amplification, including the mediating role of dysfunctional interpersonal behaviors. Method: A sample of 245 adult community members completed the Somatosensory Amplification Scale, Generalized Anxiety Disorder Scale, and abbreviated versions of the Experiences in Close Relationships scale and Inventory of Interpersonal Problems. Correlational and regression analyses were used to examine relations among study variables, including a hypothesized parallel mediation model. Results: Somatosensory amplification was significantly associated with attachment anxiety, but not attachment avoidance. Regression analyses, controlling for general anxiety symptoms and gender, found that interpersonal sensitivity (but not aggression or ambivalence) mediated the link between attachment anxiety and somatosensory amplification. Limitations: Study limitations include the use of cross-sectional data and a non-clinical sample. Conclusion: The findings indicate that somatosensory amplification may be related to individuals’ attachment anxiety, through the mediating effect of interpersonal sensitivity problems.

Efficacy of a Psychological Single-Session Intervention in Non-Cardiac Chest Pain

Abstract. Despite medical reassurance, non-cardiac chest pain (NCCP) frequently persists. Psychological interventions seem promising, but single-session interventions (SSI) are under-studied. To analyze the efficacy of a SSI focusing on chest pain perceptions in a randomized controlled trial (RCT), and to identify predictors of pain persistence. Individuals presenting with NCCP to a cardiology unit were randomly assigned to SSI ( N = 54) or treatment as usual ( N = 59). Follow-up assessments were 1 month (FU1) and 6 months (FU2) later. Primary outcome measures were chest pain (German Pain Questionnaire) and chest pain perceptions (IPQ-B, Reassurance Scale). Two by Three ANOVAs revealed significant improvements over time, but against expectation no significant interaction with group. Health concern and cardiac attribution following cardiac testing predicted FU2 chest pain ( p’s ≤ .018). These predictors could serve as markers to identify individuals with a risk for persisting complaints, a group that may benefit from interventions addressing dysfunctional illness perceptions.

Somatosensory amplification - An old construct from a new perspective

The paper reviews and summarizes the history and the development of somatosensory amplification, a construct that plays a substantial role in symptom reports. Although the association with negative affect has been supported by empirical findings, another key elements of the original concept (i.e. body hypervigilance and the tendency of focusing on mild body sensations) have never been appropriately addressed. Recent findings indicate that somatosensory amplification is connected with phenomena that do not necessarily include symptoms (e.g. modern health worries, or expectations of symptoms and medication side effects), and also with the perception of external threats. In conclusion, somatosensory amplification appears to refer to the intensification of perceived external and internal threats to the integrity of the body ("somatic threat amplification") rather than amplification of perceived or actual bodily events only. Practical implications of this new approach are also discussed.

Illness perceptions, negative emotions, and pain in patients with noncardiac chest pain

Illness-specific cognitions are associated with outcomes in numerous health conditions, however, little is known about their role in noncardiac chest pain (NCCP). NCCP is prevalent, impairing, and associated with elevated health care utilization. Our objective was to investigate the relations between illness perceptions, emotion, and pain in a sample of 196 adult patients diagnosed with NCCP. We found that negative illness perceptions were associated with greater anxiety, depression, chest pain, and pain-related life interference while controlling for the effects of demographic and pain-related variables. These results expand current NCCP theory and may inform future treatment development.

'Everything's fine, so why does it happen?' A qualitative investigation of patients' perceptions of noncardiac chest pain

Aims and objectives

To examine patients' perceptions and experiences of noncardiac chest pain, within the framework of the common sense model.

Background

Patients with noncardiac chest pain have good physical prognosis, but frequently suffer prolonged pain and psychological distress. The common sense model may provide a good framework for examining outcomes in patients with noncardiac chest pain.

Design

Qualitative thematic analysis with semi‐structured interviews.

Methods

In 2010, participants recruited from an emergency department (N = 7) with persistent noncardiac chest pain and distress were interviewed using a semi‐structured schedule, and data were analysed using thematic analysis.

Results

Seven themes were identified; six of which mapped onto core dimensions of the common sense model (identity, cause, timeline, consequences, personal control, treatment control). Contrary to previous research on medically unexplained symptoms, most participants perceived psychological factors to play a causal role in their chest pain. Participants' perceptions largely mapped onto the common sense model, although there was a lack of coherence across dimensions, particularly with regard to cause.

Conclusion

Patients with noncardiac chest pain lack understanding with regard to their condition and may be accepting of psychological causes of their pain.

Relevance to clinical practice

Brief psychological interventions aimed at improving understanding of the causes of noncardiac chest pain and providing techniques for managing pain and stress may be useful for patients with noncardiac chest pain.

Implicit affective evaluation of somatosensory sensations in patients with noncardiac chest pain

BACKGROUND AND OBJECTIVES

Etiological models of noncardiac chest pain (NCCP) stress the importance of abnormal implicit affective evaluations of somatosensory sensations, but this has never been studied empirically. The aim was therefore to assess implicit affective evaluations of somatosensory stimuli in NCCP using an experimental design.

METHODS

A total of 34 patients with NCCP, 24 patients with cardiac chest pain, and 46 healthy controls, took part in the study. Participants completed a tactile modification of the Affect Misattribution Procedure (tAMP) and answered self-report measures on anxiety sensitivity, somatosensory amplification, and somatic symptom distress.

RESULTS

A 3 × 3-ANOVA revealed that most negative judgments were found in the aversive condition, but this effect was not specific to patients with NCCP. Anxiety sensitivity was positively associated with negative implicit evaluations of aversive tactile stimuli in the tAMP.

LIMITATIONS

The task seemed to be too difficult for older participants. Also, future studies should apply clinically more relevant, e.g., heart related, stimuli that are more ecologically valid than the electrical stimulation of the finger used as a proxy for aversive somatosensory sensations here.

CONCLUSIONS

Against theoretical assumptions, patients with NCCP do not seem to show a stronger implicit negative interpretation bias concerning somatosensory sensations in comparison to patients either with cardiac chest pain, or without chest pain. Nevertheless, anxiety sensitivity seems to contribute significantly to implicit affective interpretations of somatic sensations. Further studies are required investigating the relevance of implicit interpretative processes for the course of NCCP and distressing somatic symptoms in general.

Illness representations, psychological distress and non-cardiac chest pain in patients attending an emergency department

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.
