A randomized controlled trial of cognitive behavior therapy tailored to psychological adaptation to an implantable cardioverter defibrillator

Perceived benefits of patient support groups and their format for people with an implantable cardioverter defibrillator

BACKGROUND

Support groups for people with Implantable Cardioverter Defibrillators (ICDs) are widely used, however, it is not clear what people with ICDs gain from a support group or what format they should take.

OBJECTIVES

The aim of the present study is to define the perceived benefit of ICD support groups and develop practical recommendations for group format.

METHODS

14 individuals with ICDs were interviewed using a semi-structured interview guide. Reflexive thematic analysis methods were utilised to code and analyse the transcripts before generating themes.

RESULTS

Four themes were defined: confronting mortality, coping through sharing, coping through learning, and providing space. Making connections with other people with ICDs, reassurance, access to information, and advice from health care professionals were important perceived benefits of the support group.

CONCLUSION

People with ICDs may have to confront their own mortality and adapt to considerable life changes after implant. The findings from the present study have improved understanding of how support groups are perceived and how ICD indication and group format influence the experience. A blended format of in-person community meetings, online forums, HCP-led education and space for person-person interaction is recommended. Importantly, provision of support should not be time-limited to allow people to access it when it most likely to be of benefit to them.

Impact of Preexisting Depression and Anxiety on Hospital Readmission and Long-Term Survival After Cardiac Arrest

BACKGROUND

While sudden cardiac arrest (CA) survivors are at risk for developing psychiatric disorders, little is known about the impact of preexisting mental health conditions on long-term survival or postacute healthcare utilization. We examined the prevalence of preexisting psychiatric conditions in CA patients who survived hospital discharge, characterized incidence and reason for inpatient psychiatry consultation during these patients' acute hospitalizations, and determined the association of pre-CA depression and anxiety with hospital readmission rates and long-term survival. We hypothesized that prior depression or anxiety would be associated with higher hospital readmission rates and lower long-term survival.

METHODS

We conducted a retrospective cohort study including patients resuscitated from in- and out-of-hospital CA who survived both admission and discharge from a single hospital between January 1, 2010, and December 31, 2017. We identified patients from our prospective registry, then performed a structured chart review to abstract past psychiatric history, prescription medications for psychiatric conditions, and identify inpatient psychiatric consultations. We used administrative data to identify readmissions within 1 year and vital status through December 31, 2020. We used multivariable Cox regressions controlling for patient demographics, medical comorbidities, discharge Cerebral Performance Category and disposition, depression, and anxiety history to predict long-term survival and hospital readmission.

RESULTS

We included 684 subjects. Past depression or anxiety was noted in 24% (n = 162) and 19% (n = 129) of subjects. A minority of subjects (n = 139, 20%) received a psychiatry consultation during the index hospitalization. Overall, 262 (39%) subjects had at least 1 readmission within 1 year. Past depression was associated with an increased hazard of hospital readmission (hazard ratio 1.50, 95% CI 1.11-2.04), while past anxiety was not associated with readmission. Neither depression nor anxiety were independently associated with long-term survival.

CONCLUSIONS

Depression is an independent risk factor for hospital readmission in CA survivors.

The relationship between mindfulness and enduring somatic threat severity in long-term cardiac arrest survivors

BACKGROUND

Cardiac arrest (CA) survivors experience continuous exposures to potential traumas though chronic cognitive, physical and emotional sequelae and enduring somatic threats (ESTs) (i.e., recurring somatic traumatic reminders of the event). Sources of ESTs can include the daily sensation of an implantable cardioverter defibrillator (ICD), ICD-delivered shocks, pain from rescue compressions, fatigue, weakness, and changes in physical function. Mindfulness, defined as non-judgmental present-moment awareness, is a teachable skill that might help CA survivors cope with ESTs. Here we describe the severity of ESTs in a sample of long-term CA survivors and explore the cross-sectional relationship between mindfulness and severity of ESTs.

METHODS

We analyzed survey data of long-term CA survivors who were members of the Sudden Cardiac Arrest Foundation (collected 10-11/2020). We assessed ESTs using 4 cardiac threat items from the Anxiety Sensitivity Index-revised (items range from 0 "very little" to 4 "very much") which we summed to create a score reflecting total EST burden (range 0-16). We assessed mindfulness using the Cognitive and Affective Mindfulness Scale-Revised. First, we summarized the distribution of EST scores. Second, we used linear regression to describe the relationship between mindfulness and EST severity adjusting for age, gender, time since arrest, COVID-19-related stress, and loss of income due to COVID.

RESULTS

We included 145 CA survivors (mean age: 51 years, 52% male, 93.8% white, mean time since arrest: 6 years, 24.1% scored in the upper quarter of EST severity). Greater mindfulness (β: -30, p = 0.002), older age (β: -0.30, p = 0.01) and longer time since CA (β: -0.23, p = 0.005) were associated with lower EST severity. Male sex was also associated with greater EST severity (β: 0.21, p = 0.009).

CONCLUSION

ESTs are common among CA survivors. Mindfulness may be a protective skill that CA survivors use to cope with ESTs. Future psychosocial interventions for the CA population should consider using mindfulness as a core skill to reduce ESTs.

Addressing PTSD in Implantable Cardioverter Defibrillator Patients: State-of-the-Art Management of ICD Shock and PTSD

PURPOSE OF REVIEW

This paper reviews the unique processes and treatments of post-traumatic stress in implantable cardioverter-defibrillator (ICD) patients and posits specific clinical management recommendations.

RECENT FINDINGS

PTSD is a common presenting problem for a prospective ICD patient and is a common response to ICD shocks. Approximately 32% of patients with sudden cardiac arrest report significant PTSD symptoms. Following ICD shock, approximately 20% experience PTSD from the shocks. Regardless, PTSD can interrupt and undermine clinical management from a cardiologist perspective and create significant disturbance in patients and families. Few cardiology clinics are outfitted to effectively manage psychological distress, in general, and PTSD, in particular. Effective management of PTSD patients can be achieved with both direct care in the cardiac clinic, as well as indirect care via multidisciplinary consultation and expertise. The importance of emotional validation, return to physical activity, and family engagement is emphasized in current management.

Benefits of support groups for patients living with implantable cardioverter defibrillators: a mixed-methods systematic review and meta-analysis

BACKGROUND

Patients with implantable cardioverter defibrillators (ICD) experience anxiety, depression and reduced quality of life (QoL).

OBJECTIVES

This mixed-methods systematic review evaluates whether ICD support groups have a beneficial effect on mental well-being.

METHODS

Literature searches were carried out in MEDLINE, Embase, CINAHL, PsycINFO and Web of Science. Eligible studies investigated patient-led support groups for ICD patients aged 18 years or older, using any quantitative or qualitative design. The Mixed-Methods Assessment Tool was used to assess quality. Meta-analysis of measures of mental well-being was conducted. Thematic synthesis was used to generate analytic themes from the qualitative data. The data were integrated and presented using the Pillar Integration Process.

RESULTS

Ten studies were included in this review. All studies bar one were non-randomised or had a qualitative design and patients had self-selected to attend a support group. Five contributed to the quantitative data synthesis and seven to the qualitative synthesis. Meta-analysis of anxiety and QoL measures showed no significant impact of support groups on mental well-being, but qualitative data showed that patients perceived benefit from attendance through sharing experiences and acceptance of life with an ICD.

DISCUSSION

ICD support group attendance improved the patients' perceived well-being. Attendees value the opportunity to share their experiences which helps to accept their new life with an ICD. Future research could consider outcomes such as patient acceptance and the role of healthcare professionals at support groups.

Supportive psychological therapy can effectively treat post-stroke post-traumatic stress disorder at the early stage

Post-traumatic stress disorder (PTSD) can develop after stroke attacks, and its rate ranges from 4 to 37% in the stroke population. Suffering from PTSD not only decreases stroke patient’s quality of life, but also relates to their non-adherence of treatment. Since strokes often recur and progress, long-term medical management is especially important. However, previous studies generally focused on the epidemiological characteristics of post-stroke PTSD, while there are literally no studies on the psychological intervention. In our study, 170 patients with a first-ever stroke during the acute phase were recruited. They were randomized into Psycho-therapy group 1 and Control group 1, and were administered with preventive intervention for PTSD or routine health education, respectively. At 2-month follow-up, PTSD symptoms were evaluated. Participants who were diagnosed with post-stroke PTSD were further randomized into Psycho-therapy group 2 and Control group 2, and received supportive therapy or routine health counseling, respectively. At 6-month follow-up (1°month after the therapy was completed), PTSD symptoms were re-evaluated. Our results showed that at 2-month, the PTSD incidence in our series was 11.69%, and the severity of stroke was the only risk factor for PTSD development. The preventive intervention was not superior to routine health education for PTSD prevention. At 6-month, results indicated the supportive therapy did have a fine effect in ameliorating symptoms for diagnosed PTSD patients, superior to routine health counseling. Thus, our study was the first to provide evidence that the supportive therapy was effective in treating post-stroke PTSD early after its diagnosis. This clinical trial was preregistered on www.chictr.org.cn (ChiCTR2100048411).

Career Development, Institutional Factors, Social Factors and Urban Young Returnees’ Happiness in the Context of Healthy China

In the context of the Healthy China 2030 Plan, the importance of the happiness of urban young returnees should not be underestimated. Based on a large-scale social survey of social practices in China, this paper applies a hierarchical linear regression model (HLM) and a structural equation model (SEM) to investigate the determinants of urban young returnees’ happiness. The results show that the happiness of urban young returnees in China is not only influenced by their socio-demographic characteristics, such as age and education, but mainly by their occupational development, institutional factors (especially the employment and entrepreneurship policy system) and social factors (physical environment and urban rural relationship), which are different from those of ordinary residents. Further study shows that occupational development indirectly affects the happiness of urban young returnees through relationship adaptation, collective adaptation and material adaptation, the indirect effects accounts for 42.18%, 21.64% and 36.18%, respectively. Institutional factors exert an indirect effect on the happiness of urban young returnees through relationship adaptation (46.80%) and material adaptation (53.20%). Social factors indirectly affect the happiness of urban young returnees through relationship adaptation (44.20%), collective adaptation (16.96%) and material adaptation (38.84%). Policies to improve the happiness of urban young returnees are suggested.

A Public Health Perspective of Post-Traumatic Stress Disorder

Trauma exposure is one of the most important and prevalent risk factors for mental and physical ill-health. Prolonged or excessive stress exposure increases the risk of a wide variety of mental and physical symptoms, resulting in a condition known as post-traumatic stress disorder (PTSD). The diagnosis might be challenging due to the complex pathophysiology and co-existence with other mental disorders. The prime factor for PTSD development is exposure to a stressor, which variably, along with peritraumatic conditions, affects disease progression and severity. Additionally, many factors are thought to influence the response to the stressor, and hence reshape the natural history and course of the disease. With sufficient knowledge about the disease, preventive and intervenient methods can be implemented to improve the quality of life of the patients and to limit both the medical and economic burden of the disease. This literature review provides a highlight of up-to-date literature on traumatic stress, with a focus on causes or triggers of stress, factors that influence response to stress, disease burden, and the application of the social-ecological public health model of disease prevention. In addition, it addresses therapeutic aspects, ethnic differences in traumatic stress, and future perspectives, including potential biomarkers.

Effect of Early Psychological Counseling for the Prevention of Posttraumatic Stress Induced by Acute Coronary Syndrome at Long-Term Follow-Up

OBJECTIVE

Psychological consequences of myocardial infarction (MI) are substantial, as 4% of all MI patients develop posttraumatic stress disorder (PTSD) and 12% clinically relevant posttraumatic stress symptoms (PTSS). The study investigated the course and development within 12 months of MI-induced PTSS to gain novel insights in potentially delayed response to early trauma-focused counseling aimed at preventing the incidence of MI-induced PTSS.

METHODS

In the MI-SPRINT two-group randomized controlled trial, 190 MI-patients were randomly allocated to receive a single-session intervention of either trauma-focused counseling or an active control intervention targeting the general role of stress in patients with heart disease. Blind interviewer-rated PTSS (primary outcome) and additional health outcomes were assessed at 12-month follow-up.

RESULTS

12-month follow-up of outcomes were available for 106 (55.8%) of 190 participants: In the entire sample, one patient (0·5%, 1/190) who received trauma-focused counseling developed full PTSD. There was no significant difference between trauma-focused counseling and stress counseling regarding total score of interviewer-rated PTSS (p > 0.05). The only group difference emerged in terms of more severe hyperarousal symptoms in the trauma-focused counseling group in the ITT analysis, but not in the completer analysis.

CONCLUSIONS

No benefits were found for trauma-focused counseling after 12 months when compared with an active control intervention. PTSD prevalence in the present study was low highlighting a potential beneficial effect of both interventions. Further studies are needed to determine the most accurate approach of counseling.

Device nurse intervention facilitates the patients' adaptation to cardiac shock devices in the remote monitoring era

BACKGROUND

A substantial number of patients with shock devices (implantable cardioverter defibrillators [ICDs] or ICDs with resynchronization [CRTDs]) experience psychological distress.

OBJECTIVE

We investigated the device nurse telephone intervention's effect on improving the patient's adaptation to shock devices, quality of life (QOL), and anxiety in the remote monitoring era.

METHODS

The patient's adaptation to the device, health-related QOL, and anxiety were investigated by the modified Implanted Devices Adjustment-Japan score (IDAS), Short Form-36, and State-Trait Anxiety Inventory (STAI) before and 1-year after the device nurse telephone intervention, performed every 3 months. A total of 95 patients (median age 69 years and 25 females) participated. Sixty patients had ICDs and 35 CRTDs. Structural heart disease was observed in 72 patients, and idiopathic ventricular arrhythmias in the others. The mean left ventricular ejection fraction was 46% ± 15%. The median duration since the device implantation was 5.2 years.

RESULTS

The total IDAS score significantly improved from 28.42 ± 7.11 at baseline to 26.77 ± 7.68 (p = 0.0076) at 1 year. Both the state and trait anxiety significantly improved (from 38.9 ± 9.6 to 35.3 ± 9.0 [<0.0001] and 38.8 ± 10.3 to 36.2±9.8 [p = 0.0044], respectively). The prevalence of patients with a state and trait anxiety of more than 40 decreased from 44 (46%) and 38 (40%) patients before the study to 27 (28 %) and 32 (34 %) at 1 year. The SF-36 mental component summary score significantly increased (50.8 ± 8.3 at baseline to 53.1 ± 7.7 at 1 year, p = 0.0031).

CONCLUSIONS

The device nurse intervention facilitated the patient's adaptation to the shock device, increased the health-related QOL, and reduced the patient's anxiety.

Acceptance of disability predicts quality of life in patients with epilepsy

BACKGROUND

Acceptance of disability (AOD) is a key concept in rehabilitation psychology that enhances psychosocial adjustment of individuals with disability. However, the impact of AOD on well-being has never been examined for patients with epilepsy. The present study investigated whether AOD affects quality of life (QOL) in patients with epilepsy in the presence of other multiple aspects of epilepsy based on the biopsychosocial model.

METHODS

We retrospectively reviewed 151 consecutive patients with epilepsy (77 men, aged 18-74 years) who underwent comprehensive assessment including long-term video-EEG monitoring, neuroimaging studies, and neuropsychological and psychosocial assessment in our epilepsy monitoring unit. Data were obtained from medical records and self-reported questionnaires. The outcome variable was QOL. Predictive variables included demographic characteristics, seizure-related variables (i.e., duration of epilepsy, seizure frequency, and number of antiepileptic drugs), psychological factors (i.e., AOD, depression, and self-stigma), and social factors (i.e., social support and education level). Acceptance of disability was measured by the Adaptation of Disability Scale-Revised (ADS-R), which we translated into Japanese with the original author's approval, and examined its internal consistency reliability. Data were analyzed using four hierarchical multiple regression analysis models.

RESULTS

The mean ADS-R score was 80 (range 45-115). The predictors accounted for 42% of the variance in QOL (R² = 0.45, ΔR² = 0.42, F[8, 141] = 14.47, p = 0.00). Higher AOD (p < 0.01), higher social support (p < 0.01), and lower depression scores (p = 0.02) were found to contribute significantly to higher overall QOL.

CONCLUSION

The present study revealed AOD as an important psychological concept, in addition to social support and depression as previously reported, to improve the QOL of patients with epilepsy. Acceptance of disability should be incorporated in the intervention to increase QOL of patients with epilepsy.

Preventing the onset of post traumatic stress disorder

Post-traumatic stress disorder (PTSD) is a common mental health condition that requires exposure to a traumatic event. This provides unique opportunities for prevention that are not available for other disorders. The aim of this review was to undertake a systematic review and evaluation of randomized controlled trials (RCTs) of interventions designed to prevent PTSD in adults. Searches involving Cochrane, Embase, Medline, PsycINFO, PILOTS and Pubmed databases were undertaken to identify RCTs of pre-incident preparedness and post-incident interventions until May 2019. Six pre-incident and 69 post-incident trials were identified that could be included in meta-analyses. The overall quality of the evidence was low. There was emerging evidence that some interventions may be helpful but an absence of evidence for any intervention that can be strongly recommended for universal, selected or indicated prevention before or within the first three months of a traumatic event. The strongest results were found for cognitive-behavioural therapy with a trauma focus (CBT-T) in individuals with a diagnosis of acute stress disorder which supports calls to detect and treat individuals with significant symptoms rather than providing blanket preventative interventions. Further research is required to optimally configure existing interventions with some evidence of effect and to develop novel interventions to address this major public health issue.

Course, Moderators, and Predictors of Acute Coronary Syndrome-Induced Post-traumatic Stress: A Secondary Analysis From the Myocardial Infarction-Stress Prevention Intervention Randomized Controlled Trial

Acute coronary syndromes (ACS) induce post-traumatic stress symptoms (PTSS) in one out of eight patients. Effects of preventive interventions, the course and potential moderators of ACS-induced PTSS are vastly understudied. This study explored whether a preventive behavioral intervention leads to a decrease in myocardial infarction (MI)-induced PTSS between two follow-up assessments. Sociodemographic, clinical and psychological factors were additionally tested as both moderators of change over time in PTSS and predictors of PTSS across two follow-ups. Within 48 h after reaching stable circulatory conditions, 104 patients with MI were randomized to a 45-min one-session intervention of either trauma-focused counseling or stress counseling (active control). Sociodemographic, clinical, and psychological data were collected at baseline, and PTSS were assessed with the Clinician-Administered Post-traumatic Stress Disorder Scale 3 and 12 months post-MI. PTSS severity showed no change over time from 3 to 12 months post-MI, either in all patients or through the intervention [mean group difference for total PTSS = 1.6 (95% CI -1.8, 4.9), re-experiencing symptoms = 0.8 (95% CI -0.7, 2.2), avoidance/numbing symptoms = 0.1 (95% CI -1.6, 1.7) and hyperarousal symptoms = 0.6 (95% CI -0.9, 2.1)]. Patients receiving one preventive session of trauma-focused counseling showed a decrease from 3 to 12 months post-MI in avoidance symptoms with higher age (p = 0.011) and direct associations of clinical burden indices with total PTSS across both follow-ups (p's ≤ 0.043; interaction effects). Regardless of the intervention, decreases in re-experiencing, avoidance and hyperarousal symptoms from 3 to 12 months post-MI occurred, respectively, in men (p = 0.006), participants with low education (p = 0.014) and with more acute stress symptoms (p = 0.021). Peritraumatic distress (p = 0.004) and lifetime depression (p = 0.038) predicted total PTSS across both follow-ups. We conclude that PTSS were persistent in the first year after MI and not prevented by an early one-session intervention. A preventive one-session intervention of trauma-focused counseling may be inappropriate for certain subgroups of patients, although this observation needs confirmation. As predictors of the development and persistence of PTSS, sociodemographic and psychological factors could help to identify high-risk patients yet at hospital admission.

Anxiety, depression, ventricular arrhythmias and mortality in patients with an implantable cardioverter defibrillator: 7 years' follow-up of the MIDAS cohort

OBJECTIVE

To examine whether anxiety and depression at time of implantation of an implantable cardioverter defibrillator (ICD) is associated with ventricular arrhythmias (VAs) and mortality 7 years later.

METHODS

A cohort of 399 patients (80% men; mean (SD) age = 58.3 (12.2)) implanted with an ICD completed the Hospital Anxiety and Depression Scale (HADS) and the State-Trait Anxiety Inventory at time of implantation. Patients were followed up for VAs and mortality at 7 years.

RESULTS

At 7-years follow-up, 34% of the patients had died and 38% had experienced VAs. Baseline depression (score ≥ 8) (HR:2.10; 95% CI:1.44-3.05, p < 0.001) was associated with 7-year mortality in adjusted analyses while state anxiety (score ≥ 40) (HR:1.45; 95% CI:1.02-2.06, p = 0.039) and trait anxiety (score ≥ 40) (HR:1.51; 95% CI:1.06-2.16, p = 0.022) showed a trend towards an association with mortality. No association was found between VAs and anxiety and depression. There was a dose-response relationship with higher burden of anxiety (HR:2.13; 95% CI:1.31-3.46, p = 0.002) and depression (HR:2.13; 95% CI:1.33-3.42, p = 0.002) measured with the HADS (scores < 8, 8-10 and > 10) being associated with an increased risk of mortality.

CONCLUSION

Patients with depression had greater risk of mortality, whereas anxiety only showed a trend. Neither anxiety nor depression was associated with VAs during follow-up.

Social cognitive intervention following an initial implantable cardioverter defibrillator: Better treatment response for secondary versus primary prevention

BACKGROUND

The patient + partner (P+P) is a patient/partner-focused social cognitive intervention with demonstrated efficacy to improve outcomes following an initial implantable cardioverter defibrillator (ICD). Little is known about how the patient response may differ by ICD implant indication. The aim of this study was to examine the response to intervention for patients with an initial ICD by reasons for primary versus secondary ICD indication.

METHOD

A longitudinal secondary analysis of data from a randomized clinical trial testing the P+P intervention examined patient health outcomes over 12 months, stratified by the indication for the ICD: primary prevention without cardiac resynchronization therapy (CRT) (1^o No CRT, n = 100), primary prevention with CRT (1^o CRT, n = 78), secondary prevention after cardiac arrest (2° Cardiac Arrest, n = 66), and secondary prevention for other arrhythmias (2^o Other, n = 57). Outcomes included physical and mental health status (Short-Form-36 Physical Component Summary and Mental Component Summary), physical symptoms (Patient Concerns Assessment), depression (Patient-Health-Questionniare-9), and anxiety (State-Trait Anxiety Inventory).

RESULTS

Participants (n = 301) were on average 64 years old, primarily male (73.7%) and Caucasian (91%) with reduced ejection fraction (34%). There were no baseline differences between ICD groups for all outcomes (P > .05). Patients in the 2° Cardiac Arrest group showed greater improvement from baseline to 3 months in physical and mental health outcomes. The 2° Cardiac Arrest group had better physical (F = 11.48, P = .004) and mental health (F = 4.34, P = .038) and less severe physical (z = 2.24, P = 0.013) and depressive symptoms (z = 2.71, P = .003) at 12 months compared to the 1^o No CRT group.

CONCLUSION

The P+P intervention was more effective for promoting physical and psychological health outcomes for individuals receiving an ICD for 2^o prevention after cardiac arrest.

Multisymptom Profile Predicts Increased Risk of Poor Outcomes After Initial Placement of Implantable Cardioverter Defibrillator

CONTEXT

Patients with implantable cardioverter defibrillators (ICDs) are at risk for multiple physical and psychological symptoms. Identification of specific symptom profiles associated with poor outcomes may elucidate novel strategies to enhance symptom management.

OBJECTIVES

The objectives were to determine common symptoms after initial ICD implantation, identify classes of individuals with similar symptom profiles, describe patient characteristics associated with different symptom profiles, and determine if symptom profiles at hospital discharge predicted outcomes three and 12 months after implantation.

METHODS

This was a secondary data analysis of a randomized controlled trial that compared patient + partner versus patient-only interventions designed to help patients manage symptoms, prepare for ICD shocks, and resume daily activities. Symptoms were measured with the Patient Concerns Assessment. Latent class regression analysis was used to identify symptom classes at baseline, three-month, and 12-month follow-up. Associations between patient characteristics, class membership, and outcomes were examined using chi-square, analysis of variance, and Poisson regression.

RESULTS

The study included 301 patients (74% male, mean age 64 ± 11.9 years). Three classes were identified: Multi-Symptom (N = 119, 40%), Tired-Rundown (N = 130, 43%), and Mostly Asymptomatic (N = 52, 17%). Patients in the Multi-Symptom class were younger (59.9 years, P < 0.001) and reported more anxiety (P < 0.001) and depression (P < 0.01) than the other classes. Membership in the Multi-Symptom class predicted lower quality of life and resulted in nearly double the rate of hospitalizations after 12 months (P = 0.02, IRR 1.9).

CONCLUSION

Evaluation of symptom profiles after ICD implantation offers a promising strategy for identifying patients at risk for poor health outcomes.

Cognitive behavioural therapy significantly reduces anxiety in patients with implanted cardioverter defibrillator compared with usual care: Findings from the Screen-ICD randomised controlled trial

AIM

The aim of this study was to investigate the effect of a cognitive behavioural therapy intervention provided by trained cardiac nurses plus usual care compared with usual care alone in patients with an implanted cardioverter defibrillator who, prior to randomization, had presented with symptoms of anxiety measured by the Hospital Anxiety and Depression Scale.

BACKGROUND

Around 20-25% of all patients with an implanted cardioverter defibrillator experience anxiety. Among these patients anxiety is associated with mortality, presumably explained by risk behaviour and activation of the autonomic nervous system. We hypothesised that cognitive behavioural therapy provided by cardiac nurses in an out-patient setting would be an effective treatment of anxiety.

METHODS

This was an investigator-initiated randomised clinical superiority trial with blinded outcome assessment, with 1:1 randomisation to cognitive behavioural therapy plus usual care or to usual care. The primary outcome was Hospital Anxiety and Depression Scale-Anxiety mean score at 16 weeks. Secondary outcomes included Hospital Anxiety and Depression Scale-Depression, Becks Anxiety Inventory, HeartQoL and Hamilton Anxiety Scale. Primary outcome analysis was based on the intention-to-treat principle.

RESULTS

A total of 88 participants were included, 66% men, mean age 64.3 years and 61% had primary indication implantable cardioverter defibrillator. A significant difference after 16 weeks was found between groups: intervention group (Hospital Anxiety and Depression Scale-A mean (standard deviation) 4.95 points (3.30) versus usual care group 8.98 points (4.03) (p < 0.0001)). Cohen's d was -0.86, indicating a strong clinical effect. The effect was supported by secondary outcomes.

CONCLUSION

Cognitive behavioural therapy provided by cardiac nurses to patients with a positive screening for anxiety had a statistically and clinically significant effect on anxiety compared with patients not receiving cognitive behavioural therapy.

Multiple session early psychological interventions for the prevention of post-traumatic stress disorder

BACKGROUND

The prevention of long-term psychological distress following traumatic events is a major concern. Systematic reviews have suggested that individual psychological debriefing is not an effective intervention at preventing post-traumatic stress disorder (PTSD). Over the past 20 years, other forms of intervention have been developed with the aim of preventing PTSD.

OBJECTIVES

To examine the efficacy of psychological interventions aimed at preventing PTSD in individuals exposed to a traumatic event but not identified as experiencing any specific psychological difficulties, in comparison with control conditions (e.g. usual care, waiting list and no treatment) and other psychological interventions.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, PsycINFO and ProQuest's Published International Literature On Traumatic Stress (PILOTS) database to 3 March 2018. An earlier search of CENTRAL and the Ovid databases was conducted via the Cochrane Common Mental Disorders Controlled Trial Register (CCMD-CTR) (all years to May 2016). We handsearched reference lists of relevant guidelines, systematic reviews and included study reports. Identified studies were shared with key experts in the field.We conducted an update search (15 March 2019) and placed any new trials in the 'awaiting classification' section. These will be incorporated into the next version of this review, as appropriate.

SELECTION CRITERIA

We searched for randomised controlled trials of any multiple session (two or more sessions) early psychological intervention or treatment designed to prevent symptoms of PTSD. We excluded single session individual/group psychological interventions. Comparator interventions included waiting list/usual care and active control condition. We included studies of adults who experienced a traumatic event which met the criterion A1 according to the Diagnostic and Statistical Manual (DSM-IV) for PTSD.

DATA COLLECTION AND ANALYSIS

We entered data into Review Manager 5 software. We analysed categorical outcomes as risk ratios (RRs), and continuous outcomes as mean differences (MD) or standardised mean differences (SMDs), with 95% confidence intervals (CI). We pooled data with a fixed-effect meta-analysis, except where there was heterogeneity, in which case we used a random-effects model. Two review authors independently assessed the included studies for risk of bias and discussed any conflicts with a third review author.

MAIN RESULTS

This is an update of a previous review.We included 27 studies with 3963 participants. The meta-analysis included 21 studies of 2721 participants. Seventeen studies compared multiple session early psychological intervention versus treatment as usual and four studies compared a multiple session early psychological intervention with active control condition.Low-certainty evidence indicated that multiple session early psychological interventions may be more effective than usual care in reducing PTSD diagnosis at three to six months' follow-up (RR 0.62, 95% CI 0.41 to 0.93; I² = 34%; studies = 5; participants = 758). However, there was no statistically significant difference post-treatment (RR 1.06, 95% CI 0.85 to 1.32; I² = 0%; studies = 5; participants = 556; very low-certainty evidence) or at seven to 12 months (RR 0.94, 95% CI 0.20 to 4.49; studies = 1; participants = 132; very low-certainty evidence). Meta-analysis indicated that there was no statistical difference in dropouts compared with usual care (RR 1.34, 95% CI 0.91 to 1.95; I² = 34%; studies = 11; participants = 1154; low-certainty evidence) .At the primary endpoint of three to six months, low-certainty evidence indicated no statistical difference between groups in reducing severity of PTSD (SMD -0.10, 95% CI -0.22 to 0.02; I² = 34%; studies = 15; participants = 1921), depression (SMD -0.04, 95% CI -0.19 to 0.10; I² = 6%; studies = 7; participants = 1009) or anxiety symptoms (SMD -0.05, 95% CI -0.19 to 0.10; I² = 2%; studies = 6; participants = 945).No studies comparing an intervention and active control reported outcomes for PTSD diagnosis. Low-certainty evidence showed that interventions may be associated with a higher dropout rate than active control condition (RR 1.61, 95% CI 1.11 to 2.34; studies = 2; participants = 425). At three to six months, low-certainty evidence indicated no statistical difference between interventions in terms of severity of PTSD symptoms (SMD -0.02, 95% CI -0.31 to 0.26; I² = 43%; studies = 4; participants = 465), depression (SMD 0.04, 95% CI -0.16 to 0.23; I² = 0%; studies = 2; participants = 409), anxiety (SMD 0.00, 95% CI -0.19 to 0.19; I² = 0%; studies = 2; participants = 414) or quality of life (MD -0.03, 95% CI -0.06 to 0.00; studies = 1; participants = 239).None of the included studies reported on adverse events or use of health-related resources.

AUTHORS' CONCLUSIONS

While the review found some beneficial effects of multiple session early psychological interventions in the prevention of PTSD, the certainty of the evidence was low due to the high risk of bias in the included trials. The clear practice implication of this is that, at present, multiple session interventions aimed at everyone exposed to traumatic events cannot be recommended. There are a number of ongoing studies, demonstrating that this is a fast moving field of research. Future updates of this review will integrate the results of these new studies.

Early interventions to prevent posttraumatic stress disorder symptoms in survivors of life-threatening medical events: A systematic review

Post-traumatic stress disorder (PTSD) induced by life-threatening medical events has been associated with adverse physical and mental health outcomes, but it is unclear whether early interventions to prevent the onset of PTSD after these events are efficacious. We conducted a systematic review to address this need. We searched six biomedical electronic databases from database inception to October 2018. Eligible studies used randomized designs, evaluated interventions initiated within 3 months of potentially traumatic medical events, included adult participants, and did not have high risk of bias. The 21 included studies (N = 4,486) assessed a heterogeneous set of interventions after critical illness (9), cancer diagnosis (8), heart disease (2), and cardiopulmonary surgery (2). Fourteen psychological, 2 pharmacological, and 5 other-type interventions were assessed. Four of the psychological interventions emphasizing cognitive behavioral therapy or meaning-making, 1 other-type palliative care intervention, and 1 pharmacological-only intervention (hydrocortisone administration) were efficacious at reducing PTSD symptoms relative to control. One early, in-hospital counseling intervention was less efficacious at lowering PTSD symptoms than an active control. Clinical and methodological heterogeneity prevented quantitative pooling of data. While several promising interventions were identified, strong evidence of efficacy for any specific early PTSD intervention after medical events is currently lacking.

Exercise-based cardiac rehabilitation for adult patients with an implantable cardioverter defibrillator

BACKGROUND

An effective way of preventing sudden cardiac death is the use of an implantable cardioverter defibrillator (ICD). In spite of the potential mortality benefits of receiving an ICD device, psychological problems experienced by patients after receiving an ICD may negatively impact their health-related quality of life, and lead to increased readmission to hospital and healthcare needs, loss of productivity and employment earnings, and increased morbidity and mortality. Evidence from other heart conditions suggests that cardiac rehabilitation should consist of both exercise training and psychoeducational interventions; such rehabilitation may benefit patients with an ICD. Prior systematic reviews of cardiac rehabilitation have excluded participants with an ICD. A systematic review was therefore conducted to assess the evidence for the use of exercise-based intervention programmes following implantation of an ICD.

OBJECTIVES

To assess the benefits and harms of exercise-based cardiac rehabilitation programmes (exercise-based interventions alone or in combination with psychoeducational components) compared with control (group of no intervention, treatment as usual or another rehabilitation programme with no physical exercise element) in adults with an ICD.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase and four other databases on 30 August 2018 and three trials registers on 14 November 2017. We also undertook reference checking, citation searching and contacted study authors for missing data.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) if they investigated exercise-based cardiac rehabilitation interventions compared with no intervention, treatment as usual or another rehabilitation programme. The trial participants were adults (aged 18 years or older), who had been treated with an ICD regardless of type or indication.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data and assessed risk of bias. The primary outcomes were all-cause mortality, serious adverse events and health-related quality of life. The secondary outcomes were exercise capacity, antitachycardia pacing, shock, non-serious adverse events, employment or loss of employment and costs and cost-effectiveness. Risk of systematic errors (bias) was assessed by evaluation of predefined bias risk domains. Clinical and statistical heterogeneity were assessed. Meta-analyses were undertaken using both fixed-effect and random-effects models. We used the GRADE approach to assess the quality of evidence.

MAIN RESULTS

We identified eight trials published from 2004 to 2017 randomising a total of 1730 participants, with mean intervention duration of 12 weeks. All eight trials were judged to be at overall high risk of bias and effect estimates are reported at the end of the intervention with a follow-up range of eight to 24 weeks.Seven trials reported all-cause mortality, but deaths only occurred in one trial with no evidence of a difference between exercise-based cardiac rehabilitation and control (risk ratio (RR) 1.96, 95% confidence interval (CI) 0.18 to 21.26; participants = 196; trials = 1; quality of evidence: low). There was also no evidence of a difference in serious adverse events between exercise-based cardiac rehabilitation and control (RR 1.05, 95% CI 0.77 to 1.44; participants = 356; trials = 2; quality of evidence: low). Due to the variation in reporting of health-related quality of life outcomes, it was not possible to pool data. However, the five trials reporting health-related quality of life at the end of the intervention, each showed little or no evidence of a difference between exercise-based cardiac rehabilitation and control.For secondary outcomes, there was evidence of a higher pooled exercise capacity (peak VO₂) at the end of the intervention (mean difference (MD) 0.91 mL/kg/min, 95% CI 0.60 to 1.21; participants = 1485; trials = 7; quality of evidence: very low) favouring exercise-based cardiac rehabilitation, albeit there was evidence of substantial statistical heterogeneity (I² = 78%). There was no evidence of a difference in the risk of requiring antitachycardia pacing (RR 1.26, 95% CI 0.84 to 1.90; participants = 356; trials = 2; quality of evidence: moderate), appropriate shock (RR 0.56, 95% CI 0.20 to 1.58; participants = 428; studies = 3; quality of evidence: low) or inappropriate shock (RR 0.60, 95% CI 0.10 to 3.51; participants = 160; studies = 1; quality of evidence: moderate).

AUTHORS' CONCLUSIONS

Due to a lack of evidence, we were unable to definitively assess the impact of exercise-based cardiac rehabilitation on all-cause mortality, serious adverse events and health-related quality of life in adults with an ICD. However, our findings do provide very low-quality evidence that patients following exercise-based cardiac rehabilitation experience a higher exercise capacity compared with the no exercise control. Further high-quality randomised trials are needed in order to assess the impact of exercise-based cardiac rehabilitation in this population on all-cause mortality, serious adverse events, health-related quality of life, antitachycardia pacing and shock.

Early psychological intervention following recent trauma: A systematic review and meta-analysis

Background: Post-traumatic stress disorder (PTSD) is a common and debilitating disorder which has a significant impact on the lives of sufferers. A number of early psychological interventions have been developed to try to prevent chronic difficulties. Objective: The objective of this study was to establish the current evidence for the effectiveness of multiple session early psychological interventions aimed at preventing or treating traumatic stress symptoms beginning within three months of trauma exposure. Methods: Randomized controlled trials of early multiple session psychological interventions aimed at preventing or reducing traumatic stress symptoms of individuals exposed to a traumatic event, fulfiling trauma criteria for an ICD or DSM diagnosis of PTSD were identified through a search of the Cochrane Common Mental Disorders Group Clinical Trials Registers database, the Cochrane Central Register of Controlled Trials, MEDLINE, Embase, PsycINFO and PILOTS. Two authors independently extracted study details and data and completed risk of bias assessments. Analyses were undertaken using Review Manager software. Quality of findings were rated according to 'Grades of Recommendation, Assessment, Development, and Evaluation' (GRADE) and appraised for clinical importance. Results: Sixty-one studies evaluating a variety of interventions were identified. For individuals exposed to a trauma who were not pre-screened for traumatic stress symptoms there were no clinically important differences between any intervention and usual care. For individuals reporting traumatic stress symptoms we found clinically important evidence of benefits for trauma-focused cognitive-behavioural therapy (CBT-T), cognitive therapy without exposure and eye movement desensitization and reprocessing (EMDR). Differences were greatest for those diagnosed with acute stress disorder (ASD) and PTSD. Conclusions: There is evidence for the effectiveness of several early psychological interventions for individuals with traumatic stress symptoms following trauma exposure, especially for those meeting the diagnostic threshold for ASD or PTSD. Evidence is strongest for trauma-focused CBT.

Psychological symptoms and subsequent healthy lifestyle after a colorectal cancer diagnosis

OBJECTIVE

Although medical professionals recommend lifestyle changes following a colorectal cancer (CRC) diagnosis to improve outcomes, such changes are not consistently implemented. This study examines whether higher distress is associated with lower likelihood of engaging in favorable behaviors after CRC diagnosis.

METHOD

Women from the Nurses' Health Study prospective cohort who completed anxiety (n = 145) and depression (n = 227) symptom scales within 4 years after receiving a CRC diagnosis were included. Measures of lifestyle (diet, physical activity, alcohol, smoking, body mass index [BMI]) were queried prediagnosis, when psychological symptoms were assessed (1988 and 1992, respectively), and then every 4 years thereafter until 2010. Women were categorized according to initial psychological symptoms levels and followed through 2010 or until last follow-up completed.

RESULTS

Higher versus lower anxiety symptoms were significantly related to unhealthier lifestyle scores throughout follow-up (β = -0.25, CI [-0.44, -0.05]); however, the rate of change over time was similar across groups (pinteraction effect = 0.41). Stratified analyses hinted that higher anxiety and depression symptoms were related to increased odds of reporting a future unhealthy lifestyle within 10-years postdiagnosis. Beyond 10 years, anxiety became statistically unrelated with future lifestyle, and higher depressive symptoms were associated with lower odds of subsequently having an unhealthy lifestyle, albeit nonstatistically significant (OR = 0.35, 95% CI [0.10, 1.24], p = 0.10).

CONCLUSIONS

Among women with CRC, higher anxiety and depression symptoms were associated with subsequent unhealthier lifestyle in the 10 years following diagnosis. With replication, such findings may suggest that treating psychological symptoms early in the cancer trajectory may not solely reduce psychological distress but also promote healthier lifestyle.

Exposure-Based Therapy for Symptom Preoccupation in Atrial Fibrillation: An Uncontrolled Pilot Study

Atrial fibrillation (AF) is the most common cardiac arrhythmia. Patients often experience a range of symptoms resulting in a markedly reduced quality of life, and commonly show symptom preoccupation in terms of avoidance and control behaviors. Cognitive behavior therapy (CBT) has been shown to improve symptom burden and quality of life in other somatic disorders, but has never been evaluated in patients with AF. The purpose of this study was to evaluate the potential efficacy and feasibility of an AF-specific CBT protocol in an uncontrolled pilot study. The study included 19 patients with symptomatic paroxysmal (intermittent) atrial fibrillation who were assessed pre- and posttreatment and at 6-month follow-up. The CBT lasted 10 weeks and included exposure to physical sensations similar to AF symptoms, exposure to avoided situations or activities, and behavioral activation. We observed large within-group improvements on the primary outcome AF-specific quality of life measurement AFEQT posttreatment (Cohen's d = 1.54; p < . 001) and at 6-month follow-up (d = 1.15; p < . 001). We also observed improvements in self-reported frequency and severity of AF symptoms. All participants completed the treatment and treatment satisfaction was high. This study demonstrates the potential efficacy and feasibility of a novel CBT approach to reduce symptoms and increase quality of life in AF patients.

Complications of Heart Rhythm Management Devices After Cardiac Rehabilitation Program

OBJECTIVE

The aim of this study was to examine physical and heart rhythm management device malfunction complications after participating in a cardiac rehabilitation program intervention compared with usual care.

METHOD

This study was a clinical trial of 100 patients. After randomization, intervention group patients received 8 cardiac rehabilitation program sessions for 8 weeks and follow-up phone calls. Each session consisted of exercise training, education, and psychological interventions. Data were collected at 3 points in both groups-baseline and 8 and 12 weeks after the first day of the intervention-using a researcher-designed case report form. Data were analyzed using descriptive and nonparametric tests.

RESULTS

Of the participants, 59% were men, and the sample was aged 40 to 60 years. At the 8- to 12-week follow-up, there were less physical complications among the cardiac rehabilitation group (P < .001) and no between-group differences in complications related to device malfunction. By heart rhythm device type, cardiac rehabilitation had the greatest efficacy in reducing physical complications in patients with cardioverter/defibrillators.

CONCLUSIONS

Cardiac rehabilitation reduced physical complications in patients with cardiac rhythm management devices, especially in patients with cardioverter/defibrillators. Cardiac clinical nurse specialists should recommend rehabilitation programs as part of postimplantation rhythm device treatment to decrease the risk of physical complications.

An Evidence-Based Review of Early Intervention and Prevention of Posttraumatic Stress Disorder

We present an evidence-based review of post-trauma interventions used to prevent posttraumatic stress disorder (PTSD). Literature search of PubMed from 1988 to March 2016 using keywords "Early Intervention AND Prevention of PTSD" yielded 142 articles, of which 52 intervention studies and 6 meta-analyses were included in our review. Trauma-focused cognitive behavioral therapy and modified prolonged exposure delivered within weeks of a potentially traumatic event for people showing signs of distress have the most evidence in the treatment of acute stress and early PTSD symptoms, and the prevention of PTSD. Even though several pharmacological agents have been tried, only hydrocortisone prior to high-risk surgery, severe traumatic injury, or during acute sepsis has adequate evidence for effectiveness in the reduction of acute stress symptoms and prevention of PTSD. There is an urgent need to determine the best targets for interventions after trauma to accelerate recovery and prevent PTSD.

Behavioural and emotional implications of implantable cardioverter-defibrillators in the young and in athletes

Despite the life-saving capabilities of implantable cardioverter-defibrillators, they may have implications on behavioural and emotional well-being and have been shown to negatively affect patients' psychosocial functioning. Children and CHD patients with these devices are at higher risk for complications, and therefore may have higher risk of psychosocial dysfunction including depression, anxiety, and a decrease in overall quality of life. In addition, these patients may be restricted from activities, which may also contribute to psychosocial dysfunction. Recommendations published in 2015 support a more liberal approach to athletic participation in this patient population compared with previous guidelines. Approaches to limit psychosocial dysfunction include education, minimisation of shocks, and psychosocial therapy. Psychosocial dysfunction should be assessed at each clinic visit, and information regarding intervention should be provided to patients and their families as needed. Psychosocial dysfunction may be debilitating, and healthcare providers should facilitate and support normal psychosocial function by offering resources as needed.

The Screen-ICD trial. Screening for anxiety and cognitive therapy intervention for patients with implanted cardioverter defibrillator (ICD): a randomised controlled trial protocol

INTRODUCTION

Previous research shows that patients with an implanted cardioverter defibrillator (ICD) have a fourfold increased mortality risk when suffering from anxiety compared with ICD patients without anxiety. This research supports the screening of ICD patients for anxiety with the purpose of starting relevant intervention.

METHODS AND ANALYSIS

Screen-ICD consists of 3 parts: (1) screening of all hospitalised and outpatient patients at two university hospitals using the Hospital Anxiety and Depression Scale (HADS), scores ≥8 are invited to participate. (2) Assessment of type of anxiety by Structured Clinical Interview for DSM Disorders (SCID). (3) Investigator-initiated randomised clinical superiority trial with blinded outcome assessment, with 1:1 randomisation to cognitive-behavioural therapy (CBT) performed by a cardiac nurse with CBT training, plus usual care or usual care alone. The primary outcome is HADS-A measured at 16 weeks. Secondary outcomes include Becks Anxiety Inventory, HeartQoL, Hamilton Anxiety Scale, heart rate variability, ICD shock, time to first shock and antitachycardia pacing. A total of 88 participants will be included. The primary analyses are based on the intention-to-treat principle and we use a mixed model with repeated measurements for continuous outcomes. For binary outcomes (HADS-A score <8), we use a generalised mixed model with repeated measurements.

ETHICS AND DISSEMINATION

The trial is performed in accordance with the Declaration of Helsinki. All patients must give informed consent prior to participation and the trial is initiated after approval by the Danish Data Protection Agency (RH-2015-282) and the regional ethics committee (H-16018868). Positive, neutral and negative results of the trial will be published.

TRIAL REGISTRATION NUMBER

NCT02713360.

Effect of psycho-educational interventions on quality of life in patients with implantable cardioverter defibrillators: a meta-analysis of randomized controlled trials

Background

Implantable cardioverter defibrillators (ICD) were developed for primary and secondary prevention of sudden cardiac death. However, ICD recipients’ mortality is significantly predicted by their quality of life (QOL). The aim of this meta-analysis was to evaluate the effects of psycho-educational interventions on QOL in patients with ICDs.

Methods

We systematically searched PubMed, Medline, Cochrane Library, and CINAHL through April 2015 and references of relevant articles. Studies were reviewed if they met following criteria: (1) randomized controlled trial, (2) participants were adults with an ICD, and (3) data were sufficient to evaluate the effect of psychological or educational interventions on QOL measured by the SF-36 or SF-12. Studies were independently selected and their data were extracted by two reviewers. Study quality was evaluated using a modified Jadad scale. The meta-analysis was conducted using the Cochrane Collaboration’s Review Manager Software Package (RevMan 5). Study heterogeneity was assessed by Q statistics and I² statistic. Depending on heterogeneity, data were pooled across trials using fixed-effect or random-effect modeling.

Results

Seven randomized controlled trials fulfilled the inclusion and exclusion criteria, and included 1017 participants. The psycho-educational interventions improved physical component summary (PCS) scores in the intervention groups more than in control groups (mean difference 2.08, 95 % CI 0.86 to 3.29, p < 0.001), but did not significantly affect mental component summary (MCS) scores (mean difference 0.84, 95 % CI -1.68 to 3.35, p = 0.52).

Conclusion

Our meta-analysis demonstrates that psycho-educational interventions improved the physical component, but not the mental component of QOL in patients with ICDs.

Cognitive-Behavioral Treatment of Posttraumatic Stress in Patients With Implantable Cardioverter Defibrillators: Results From a Randomized Controlled Trial

Approximately 20% of patients with implantable cardioverter defibrillators (ICDs) suffer from posttraumatic stress disorder (PTSD) due to a history of cardiac arrest, device implantation, and ICD shock. There has been very little examination of treatment of PTSD symptoms in these patients. This study evaluated the effect of a specific cognitive-behavioral therapy (CBT) intervention for ICD patients with high levels of PTSD symptoms: a manualized program consisting of 8 telephone sessions with a trained counselor, a patient education book, and a stress management procedure on compact disc. Participants were 193 ICD patients, who were randomized to CBT or usual cardiac care (UCC) who completed self-report surveys at the time of recruitment and 6 and 12 months after initial measurement. Previous publication on the primary research evaluation questions reported that the CBT condition resulted in greater improvement on PTSD and depression symptoms than the UCC for the general population of ICD patients, but did not evaluate the effect on those with elevated symptoms of PTSD. The authors conducted secondary analyses of the effect of treatment on high and low PTSD symptom groups based on a cutoff for the Impact of Event Scale-Revised (Weiss & Marmar, 1997). Participants in the CBT group who had high symptoms experienced significantly greater symptom reduction from baseline to 12 months (d = 2.44, p = .021) than the UCC group (d = 1.12). Participants with low symptoms had small reductions regardless of group assignment (d = 0.16, p = .031). ICD-focused CBT was sufficient to produce a large, statistically significant reduction in PTSD symptoms in ICD patients with indications for treatment.

Prevention of Post-Traumatic Stress Disorder After Trauma: Current Evidence and Future Directions

Post-traumatic stress disorder (PTSD) is a frequent, tenacious, and disabling consequence of traumatic events. The disorder's identifiable onset and early symptoms provide opportunities for early detection and prevention. Empirical findings and theoretical models have outlined specific risk factors and pathogenic processes leading to PTSD. Controlled studies have shown that theory-driven preventive interventions, such as cognitive behavioral therapy (CBT), or stress hormone-targeted pharmacological interventions, are efficacious in selected samples of survivors. However, the effectiveness of early clinical interventions remains unknown, and results obtained in aggregates (large groups) overlook individual heterogeneity in PTSD pathogenesis. We review current evidence of PTSD prevention and outline the need to improve the disorder's early detection and intervention in individual-specific paths to chronic PTSD.

Adult Congenital Heart Disease-Coping And REsilience (ACHD-CARE): Rationale and methodology of a pilot randomized controlled trial

INTRODUCTION

One-third of North American adults with congenital heart disease (CHD) have diagnosable mood or anxiety disorders and most do not receive mental health treatment. There are no published interventions targeting the psychosocial needs of patients with CHD of any age. We describe the development of a group psychosocial intervention aimed at improving the psychosocial functioning, quality of life, and resilience of adults with CHD and the design of a study protocol to determine the feasibility of a potential full-scale randomized controlled trial (RCT).

METHODS/DESIGN

Drawing upon our quantitative and qualitative research, we developed the Adult CHD-Coping And REsilience (ACHD-CARE) intervention and designed a feasibility study that included a 2-parallel arm non-blinded pilot RCT. Eligible participants (CHD, age ≥ 18 years, no planned surgery, symptoms suggestive of a mood and/or anxiety disorder) were randomized to the ACHD-CARE intervention or Usual Care (1:1 allocation ratio). The group intervention was delivered during eight 90-minute weekly sessions. Feasibility will be assessed in the following domains: (i) process (e.g. recruitment and retention), (ii) resources, (iii) management, (iv) scientific outcomes, and (v) intervention acceptability.

DISCUSSION

This study underscores the importance of carefully developing and testing the feasibility of psychosocial interventions in medical populations before moving to full-scale clinical trials. At study conclusion, we will be poised to make one of three determinations for a full-scale RCT: (1) feasible, (2) feasible with modifications, or (3) not feasible. This study will guide the future evaluation and provision of psychosocial treatment for adults with CHD.

Efeitos de Intervenção Cognitivo-Comportamental sobre Fatores de Risco Psicológicos em Cardiopatas

RESUMODiminuir fatores de risco para cardiopatias pode melhorar a qualidade de vida e reduzir a mortalidade e morbidade relacionadas a elas.O presente estudo avaliou a eficácia de uma intervenção cognitivo-comportamental em grupo sobre ansiedade, depressão, estresse e saúde cardiovascular em cardiopatas. Foram avaliados 91 pacientes antes e após participação nos grupos, com entrevistas semiestruturadas, Inventários Beck (Ansiedade e Depressão) e Inventário de Sintomas de Stress para Adultos de Lipp. Coletaram-se medidas fisiológicas para cálculo do escore de Framingham. A participação no grupo resultou em redução dos sintomas de ansiedade, depressão, estresse e melhora do enfrentamento ao estresse. Não houve diferença no escore de Framingham. A intervenção se mostrou eficaz para a redução dos fatores de risco psicológicos nessa amostra.

Do genetic risk scores for body mass index predict risk of phobic anxiety? Evidence for a shared genetic risk factor

BACKGROUND

Obesity and anxiety are often linked but the direction of effects is not clear.

METHOD

Using genetic instrumental variable (IV) analyses in 5911 female participants from the Nurses' Health Study (NHS, initiated 1976) and 3697 male participants from the Health Professional Follow-up Study (HPFS, initiated 1986), we aimed to determine whether obesity increases symptoms of phobic anxiety. As instrumental variables we used the fat mass and obesity-associated (FTO) gene, the melanocortin 4 receptor (MC4R) gene and a genetic risk score (GRS) based on 32 single nucleotide polymorphisms (SNPs) that significantly predict body mass index (BMI). 'Functional' GRSs corresponding with specific biological pathways that shape BMI (adipogenesis, appetite and cardiopulmonary) were considered. The main outcome was phobic anxiety measured by the Crown Crisp Index (CCI) in 2004 in the NHS and in 2000 in the HPFS.

RESULTS

In observational analysis, a 1-unit higher BMI was associated with higher phobic anxiety symptoms [women: β = 0.05, 95% confidence interval (CI) 0.030-0.068; men: β = 0.04, 95% CI 0.016-0.071). IV analyses showed that BMI was associated with higher phobic anxiety symptoms in the FTO-instrumented analysis (p = 0.005) but not in the GRS-instrumented analysis (p = 0.256). Functional GRSs showed heterogeneous, non-significant effects of BMI on phobic anxiety symptoms.

CONCLUSIONS

Our findings do not provide conclusive evidence in favor of the hypothesis that higher BMI leads to higher levels of phobic anxiety, but rather suggest that genes that influence obesity, in particular FTO, may have direct effects on phobic anxiety, and hence that obesity and phobic anxiety may share common genetic determinants.

Phone-delivered mindfulness training for patients with implantable cardioverter defibrillators: results of a pilot randomized controlled trial

BACKGROUND

The reduction in adrenergic activity and anxiety associated with meditation may be beneficial for patients with implantable cardioverter defibrillators.

PURPOSE

This study aims to determine the feasibility of a phone-delivered mindfulness intervention in patients with defibrillators and to obtain preliminary indications of efficacy on mindfulness and anxiety.

METHODS

Clinically stable outpatients were randomized to a mindfulness intervention (eight weekly individual phone sessions) or to a scripted follow-up phone call. We used the Hospital Anxiety and Depression Scale and the Five Facets of Mindfulness to measure anxiety and mindfulness, and multivariate linear regression to estimate the intervention effect on pre-post-intervention changes in these variables.

RESULTS

We enrolled 45 patients (23 mindfulness and 22 control; age, 43-83; 30 % women). Retention was 93 %; attendance was 94 %. Mindfulness (beta = 3.31; p = 0.04) and anxiety (beta = -1.15; p = 0.059) improved in the mindfulness group.

CONCLUSIONS

Mindfulness training can be effectively phone-delivered and may improve mindfulness and anxiety in cardiac defibrillator outpatients.

Characteristics associated with anxiety, depressive symptoms, and quality-of-life in a large cohort of implantable cardioverter defibrillator recipients

OBJECTIVE

Although most patients with implantable cardioverter defibrillators (ICDs) adjust well, some have considerable psychological distress. Factors associated with psychological adjustment in ICD-recipients are still not well understood. Our purpose was to describe quality-of-life (QoL) and prevalence of self-reported symptoms of anxiety and depression in a large national cohort of ICD-recipients, and to determine socio-demographic, clinical, and ICD-related factors associated with these variables.

METHODS

A cross-sectional, correlational design was used. All eligible adult ICD-recipients in the Swedish ICD- and Pacemaker Registry were invited to participate. Symptoms of anxiety and depression were measured using the Hospital Anxiety and Depression Scale (HADS), and QoL with the EuroQol-5D.

RESULTS

A total of 3067 ICD-recipients (66±11years, 80% male) were included. The mean HADS score was 3.84±3.70 for anxiety symptoms and 2.99±3.01 for symptoms of depression. The mean EQ-5D index score was 0.82±0.21. The probability of symptoms of anxiety and depression was associated with younger age, living alone, and a previous history of myocardial infarction or heart failure. Additionally, female ICD-recipients had a higher probability of symptoms of anxiety. A higher level of ICD-related concerns was most prominently related to symptoms of anxiety, depressive symptoms and poorer QoL, while number of shocks, ICD-indication and time since implantation were not independently related.

CONCLUSIONS

In this large cohort of ICD-recipients, the association of ICD-related concerns with symptoms of anxiety, depressive symptoms, and poor QoL suggests that ICD specific factors should be addressed in order to improve outcomes.

Position paper on the importance of psychosocial factors in cardiology: Update 2013

Background: The rapid progress of psychosomatic research in cardiology and also the increasing impact of psychosocial issues in the clinical daily routine have prompted the Clinical Commission of the German Heart Society (DGK) to agree to an update of the first state of the art paper on this issue which was originally released in 2008.

Methods: The circle of experts was increased, general aspects were implemented and the state of the art was updated. Particular emphasis was dedicated to coronary heart diseases (CHD), heart rhythm diseases and heart failure because to date the evidence-based clinical knowledge is most advanced in these particular areas. Differences between men and women and over the life span were considered in the recommendations as were influences of cognitive capability and the interactive and synergistic impact of classical somatic risk factors on the affective comorbidity in heart disease patients.

Results: A IA recommendation (recommendation grade I and evidence grade A) was given for the need to consider psychosocial risk factors in the estimation of coronary risks as etiological and prognostic risk factors. Furthermore, for the recommendation to routinely integrate psychosocial patient management into the care of heart surgery patients because in these patients, comorbid affective disorders (e.g. depression, anxiety and post-traumatic stress disorder) are highly prevalent and often have a malignant prognosis. A IB recommendation was given for the treatment of psychosocial risk factors aiming to prevent the onset of CHD, particularly if the psychosocial risk factor is harmful in itself (e.g. depression) or constrains the treatment of the somatic risk factors. Patients with acute and chronic CHD should be offered anti-depressive medication if these patients suffer from medium to severe states of depression and in this case medication with selective reuptake inhibitors should be given. In the long-term course of treatment with implanted cardioverter defibrillators (ICDs) a subjective health technology assessment is warranted. In particular, the likelihood of affective comorbidities and the onset of psychological crises should be carefully considered.

Conclusions: The present state of the art paper presents an update of current empirical evidence in psychocardiology. The paper provides evidence-based recommendations for the integration of psychosocial factors into cardiological practice and highlights areas of high priority. The evidence for estimating the efficiency for psychotherapeutic and psychopharmacological interventions has increased substantially since the first release of the policy document but is, however, still weak. There remains an urgent need to establish curricula for physician competence in psychodiagnosis, communication and referral to ensure that current psychocardiac knowledge is translated into the daily routine.

Efficacy of cognitive behavioral therapy in reducing psychiatric symptoms in patients with implantable cardioverter defibrillator: an integrative review

This article is a systematic review of the available literature on the benefits that cognitive behavioral therapy (CBT) offers patients with implanted cardioverter defibrillators (ICDs) and confirms its effectiveness. After receiving the device, some patients fear that it will malfunction, or they remain in a constant state of tension due to sudden electrical discharges and develop symptoms of anxiety and depression. A search with the key words "anxiety", "depression", "implantable cardioverter", "cognitive behavioral therapy" and "psychotherapy" was carried out. The search was conducted in early January 2013. Sources for the search were ISI Web of Knowledge, PubMed, and PsycINFO. A total of 224 articles were retrieved: 155 from PubMed, 69 from ISI Web of Knowledge. Of these, 16 were written in a foreign language and 47 were duplicates, leaving 161 references for analysis of the abstracts. A total of 19 articles were eliminated after analysis of the abstracts, 13 were eliminated after full-text reading, and 11 articles were selected for the review. The collection of articles for literature review covered studies conducted over a period of 13 years (1998-2011), and, according to methodological design, there were 1 cross-sectional study, 1 prospective observational study, 2 clinical trials, 4 case-control studies, and 3 case studies. The criterion used for selection of the 11 articles was the effectiveness of the intervention of CBT to decrease anxiety and depression in patients with ICD, expressed as a ratio. The research indicated that CBT has been effective in the treatment of ICD patients with depressive and anxiety symptoms. Research also showed that young women represented a risk group, for which further study is needed. Because the number of references on this theme was small, further studies should be carried out.

Pilot study of the effect of lipophilic vs. hydrophilic beta-adrenergic blockers being taken at time of intracardiac defibrillator discharge on subsequent PTSD symptoms

A pathophysiological model of posttraumatic stress disorder (PTSD) posits that an overly strong stress response at the time of the traumatic event leads to overconsolidation of the event's memory in part through a central β-adrenergic mechanism. We hypothesized that the presence of a β-blocker in the patient's brain at the time of the traumatic event would reduce the PTSD outcome by blocking this effect. The unpredictable, uncontrollable discharge of an implantable intracardiac defibrillator (ICD) is experienced by most patients as highly stressful, and it has previously been shown to be capable of causing PTSD symptoms. The present pilot study evaluated a convenience sample of 18 male cardiac patients who had been taking either a lipophilic β-blocker (which penetrates the blood-brain barrier) or a hydrophilic β-blocker (which does not) at the time of a discharge of their ICD. The self- report PTSD Checklist-Specific Version quantified 17 PTSD symptoms pertaining to the ICD discharge during the month preceding the evaluation. There was a statistical trend for patients who had been taking a lipophilic β-blocker at the time of the ICD discharge to have (35%) less severe PTSD symptoms than patients who had been taking a hydrophilic β-blocker (one-tailed p=0.07, g=0.64). Further, prospective, randomized, controlled studies are suggested.

Synergistic application of cardiac sympathetic decentralization and comprehensive psychiatric treatment in the management of anxiety and electrical storm

We report here, for the first time, two cases demonstrating a synergistic application of bilateral cardiac sympathetic decentralization and multimodal psychiatric treatment for the assessment and management of anxiety following recurrent Implantable Cardioverter Defibrillator (ICD) shocks. In a first case the combination of bilateral cardiac sympathetic decentralization (BCSD), cognitive behavioral psychotherapy and anxiolytic medication was sufficient to attenuate the patient's symptoms and maladaptive behaviors, with a maintained benefit at 1 year. Among the more prominent subjective changes in the post-lesion state we observed a decrease in aversive interoceptive sensations, particularly of the heartbeat. The patient continued to experience cognitive threat appraisals on a frequent basis, although these were no longer incapacitating. In a second case, we report the effect of BCSD on autonomic tone and subjective state. In the post-lesion state we observed attenuated sympathetic responses to the valsalva maneuver, isometric handgrip and mental arithmetic stressor, including decreased systolic and diastolic blood pressure and, decreased skin conductance. Collectively, these preliminary findings suggest that an integrative, multidisciplinary approach to treating anxiety disorders in the setting of ventricular arrhythmias and recurrent ICD shocks can result in sustained improvements in physical, psychological, and functional status. These findings raise the possibility of a potential role for the stellate ganglion in the modulation of emotional experience and afferent transmission of interoceptive information to the central nervous system.
