Predicting post-traumatic symptoms in cardiac patients

Family-authored ICU diaries to reduce fear in patients experiencing a cardiac arrest (FAID fear): A pilot randomized controlled trial

Survivors of cardiac arrest (CA) and their family members often experience significant fear-based distress (cardiac fear; i.e., fear about the CA survivor's heart). Fear-based distress after CA is associated with higher rates of cardiac event recurrence and mortality in CA survivors. As posited in Dyadic Disruption Theory (DDT), cardiac fear in family members may contribute to the development of distress in CA survivors via socially-based mechanisms. Thus, interventions to reduce family distress may improve CA survivors' outcomes. ICU diaries are easy to implement and scalable and show promise for reducing distress after CA but are primarily targeted towards survivors. The primary aim of the Family-Authored ICU Diaries to reduce Fear in Patients Experiencing a CA (FAID Fear) pilot randomized controlled trial was to test feasibility of an ICU diary intervention targeted towards family member distress alone. Family members of patients hospitalized after CA (N = 16) were randomized 2:1 to receive the FAID Fear intervention or usual care. Intervention participants were provided brief instructions and were asked to write in the diary twice per week until the end of hospital care. Assessments occurred at baseline enrollment, end of hospital care, and 30 days later. Participants' mean age was 50.73 years (SD = 13.41; 80% cis-gender female; 60% White). Recruitment (16/25 referred; 64.0%), retention (14/16 enrolled; 87.5%), and intervention adherence (7/10 completed; 70%) were promising. Most agreed that the ICU diary intervention was appropriate (7/10 completed; 70.0%), feasible (9/10 completed; 90.0%]), and acceptable (8/10 completed; 80.0%). Fear was nonsignificantly lower in intervention participants (v. control) at end of hospital care and 30 days later. FAID Fear represents a first step in building theory-based dyadic interventions that can be implemented to support family members of CA survivors in the ICU, with potential to improve outcomes in CA survivors.

Sense of coherence and psychological well-being among coronary heart disease patients: a moderated mediation model of affect and meaning in life

There are credible data that the indirect relationship of sense of coherence with well-being can involve potential mediation and moderation mechanisms related to emotional and meaning-oriented factors. The self-concordance model provides a theoretical framework through which these associations can be examined. The current research explored whether the relationship between sense of coherence and well-being in people with coronary heart disease can be mediated by affect and simultaneously moderated by meaning in life. A total of 176 patients with coronary heart disease completed four questionnaires. Positive and negative affect turned out to mediate, though differently, the relationship between feelings of coherence and well-being. Furthermore, meaning in life moderated the indirect effect of sense of coherence to well-being only through positive affect. This confirmed the validity of a moderated mediation model of affect and meaning in life in associations between sense of coherence and well-being in people with coronary heart disease problems.

Posttraumatic stress disorder prevalence in medical populations: A systematic review and meta-analysis

OBJECTIVE

PTSD is increasingly recognized following medical traumas although is highly heterogeneous. It is difficult to judge which medical contexts have the most traumatic potential and where to concentrate further research and clinical attention for prevention, early detection and treatment. The objective of this study was to compare PTSD prevalence in different medical populations.

METHODS

A systematic review of the literature on PTSD following medical traumas was conducted as well as a meta-analysis with final pooled result and 95% confidence intervals presented. A meta-regression was used to investigate the impact of potential effect modifiers (PTSD severity, age, sex, timeline) on study effect size between prevalence studies.

RESULTS

From 3278 abstracts, the authors extracted 292 studies reporting prevalence. Using clinician-administered reports, the highest 24 month or longer PTSD prevalence was found for intraoperative awareness (18.5% [95% CI=5.1%-36.6%]) and the lowest was found for epilepsy (4.5% [95% CI=0.2%-12.6%]). In the overall effect of the meta-regression, only medical events or procedures emerged as significant (p = 0.006) CONCLUSION: This review provides clinicians with greater awareness of medical contexts most associated with PTSD, which may assist them in the decision to engage in more frequent, earlier screening and referral to mental health services.

Psychological Considerations and Interventions in Inflammatory Bowel Disease Patient Care

The presence of psychological comorbidities, specifically anxiety and depression, is well documented in inflammatory bowel disease (IBD). The drivers of these conditions typically reflect 4 areas of concern: disease impact, treatment concerns, intimacy, and stigma. Various demographic and disease characteristics increase risk for psychological distress. However, the risk for anxiety and depression is consistent throughout IBD course and is independent of disease activity. Early intervention before psychological distress becomes uncontrolled is ideal, but mental health often is unaddressed during patient visits. Understanding available psychological treatments and establishing referral resources is an important part of the evolution of IBD patient care.

Depression and post-traumatic stress disorder in individuals with hereditary hemorrhagic telangiectasia: A cross-sectional survey

INTRODUCTION

Hereditary hemorrhagic telangiectasia (HHT) is characterized by frequent severe bleeding, particularly epistaxis, and life-threatening complications including stroke, brain abscess and heart failure. The psychological impact of HHT is not known. We conducted this cross sectional study to determine the prevalence of depression and post-traumatic stress disorder (PTSD) related to HHT.

METHODS

A survey tool comprising demographic and clinical information and two validated self-administered questionnaires, the PTSD checklist for DSM-5 (PCL-5) and Beck Depression Inventory-II (BDI-II), was distributed to individuals with HHT. Associations with clinical and demographic variables with depression and PTSD were evaluated in a logistic regression model.

RESULTS

A total of 222 individuals responded to the survey. Of these, 185 completed either the BDI II or PCL-5 and were included in the analysis. Median age was 54years and 142 (76.8%) were female. An existing diagnosis of depression, anxiety disorder and PTSD was present in 81 (43.8%), 59 (31.9%) and 16(8.6%) respondents, respectively. BDI-II scores>13 indicating at least mild depressive symptoms were present in 142 (88.7%) patients and 52 (28.1%) patients had a positive screen for PTSD (PCL-5 score≥38). On multivariable analysis, depression [OR 2.17 (95% CI 1.045-4.489), p=0.038], anxiety disorder [OR 2.232 (95% CI 1.066-4.676), p=0.033], and being unemployed [OR 2.234 (95% CI 1.46-4.714), p=0.019) were associated with PTSD.

CONCLUSION

We report a high prevalence of depressive and PTSD symptoms in individuals with HHT. While selection bias may lead to overestimation of prevalence in this study, our results are concerning and clinicians should remain vigilant for signs of psychological distress and consider screening for these disorders.

Posttraumatic stress disorder after myocardial infarction and coronary artery bypass grafting

Post traumatic stress disorder is a psychiatric disease that is usually precipitated by life threatening stressors. Myocardial infarction, especially in the young can count as one such event. The development of post traumatic stress after a coronary event not only adversely effects psychiatric health, but leads to increased cardiovascular morbidity and mortality. There is increasing evidence that like major depression, post traumatic stress disorder is also a strong coronary risk factor. Early diagnosis and treatment of this disease in patients with acute manifestations of coronary artery disease can improve patient outcomes.

[Posttraumatic stress disorder : Trigger and consequence of vascular diseases]

Posttraumatic stress disorder (PTSD) was previously thought to be a psychological reaction precipitated by exposure to war, sexual and physical violence; however, PTSD is also prevalent after life-threatening medical events, such as stroke and myocardial infarction. After such events PTSD is often underdiagnosed despite the fact that it is clearly associated with adverse clinical outcomes including recurrence of cardiac events and increased mortality. Moreover, PTSD increases the risk of vascular events. This review summarizes the bidirectional relationship between PTSD and vascular diseases and outlines current knowledge regarding clinical features, prevalence and the putative underlying pathophysiological mechanisms.

Psychiatric history, post-discharge distress, and personality characteristics among incident female cases of takotsubo cardiomyopathy: A case-control study

BACKGROUND

The role of psychological factors in the onset of takotsubo cardiomyopathy (TC) is still controversial. Associations with previous psychiatric conditions are registry-based; associations with personality characteristics and psychological sequelae of TC have been largely unexplored. This case-control study sought to study pre-admission psychiatric morbidity, personality traits, and post-discharge distress in incident cases of TC.

METHODS

TC cases (Mayo clinic criteria) and acute myocardial infarction (MI) controls were recruited among women admitted to two Emergency Departments in New England. Healthy controls (HC) were recruited from a volunteers' registry. Preadmission psychiatric history (DSM-IV-TR) was abstracted from the medical record. PTSD symptoms (Impact of Events Scale); distress (Hospital Anxiety and Depression Scale); perceived stress (PS scale) and personality traits (optimism; hostility, type D personality) were collected via phone interview one month after discharge.

RESULTS

From March 2013 through October 2015, 107 participants (45 TC, 32 MI and 30 HC) were enrolled. The prevalence of preadmission anxiety disorders was 24.4% in TC, 9.4% in MI, and 0 in HC (p = 0.007) while that of mood disorders was similar across groups. TC had higher psychological distress, perceived stress, and PTSD symptoms post-discharge vs. MI and HC. In adjusted models, PTSD symptoms remained higher in TC vs. MI (b = 0.55, p < 0.05) and vs. HC (b = 0.92, p < 0.01). Optimism and hostility scores were similar across groups, while type D (social inhibition) scores were higher in TC and MI vs. HC.

CONCLUSIONS

Preadmission anxiety, but not depression, was associated with the occurrence of TC. High distress and PTSD symptoms post-discharge indicate that TC women may be at risk for poor psychological adjustment.

Reporting of Posttraumatic Stress Disorder and Cardiac Misconceptions Following Cardiac Rehabilitation

PURPOSE

Approximately 15% of cardiac patients experience posttraumatic stress disorder (PTSD), double the incidence seen in the general community. Posttraumatic stress disorder can seriously affect psychological and physical recovery. This study assessed how many patients reported symptoms of PTSD following a cardiac event and examined whether there was any change after completing a cardiac rehabilitation (CR) program. Associations between PTSD and anxiety, depression, and cardiac misconceptions were also explored.

METHODS

This was a prospective cohort study using repeated measures. All patients eligible for the hospital CR program were invited to complete questionnaires assessing psychological distress and beliefs about heart disease before (T1) and after (T2) completing the CR program.

RESULTS

Questionnaires at T1 were returned by 105 patients. Of these, 24% reported symptoms of PTSD, 18% high anxiety, and 9% high levels of depression. At T2, 67 patients returned questionnaires, showing that 9% of patients continued to experience PTSD. These patients experienced significantly higher levels of anxiety (t = -4.77; P < .001) and depression (t = -3.64; P < .001). Intrusive thoughts and hyperarousal were significantly lower at T2 (t = 2.32; P = .02 and t = 3.01; P = .01, respectively). More misconceptions were associated with higher levels of anxiety and depression; however, the number of cardiac misconceptions remained similar throughout. Caucasians reported significantly fewer misconceptions than non-Caucasian patients, except for beliefs about myocardial infarction. Patients had fewer misconceptions about their own specific condition.

CONCLUSIONS

These findings suggest that screening for symptoms of PTSD after completion of a CR program would be helpful in identifying patients who would benefit from specialist psychological support.

Fatigue two months after myocardial infarction and its relationships with other concurrent symptoms, sleep quality and coping strategies

AIMS AND OBJECTIVES

To explore fatigue levels two months after myocardial infarction and examine the associations with other concurrent symptoms, sleep quality and coping strategies.

BACKGROUND

Fatigue has been found to be the most frequent and bothersome symptom after myocardial infarction, influencing health-related quality of life negatively.

DESIGN

The present study was explorative and cross-sectional. The focus was on fatigue two months postmyocardial infarction, complemented with a comparative analysis of fatigue dimension levels.

METHODS

The sample included 142 persons (mean age 63 years), treated for myocardial infarction, who responded to a questionnaire package measuring fatigue, depression, health complaints (symptoms), sleep quality and coping strategies.

RESULTS

The main results showed that a global fatigue score two months postmyocardial infarction was associated with concurrent symptoms, such as breathlessness and stress, and coping strategies such as change in values, intrusion and isolation. In comparisons of present fatigue dimension levels (general fatigue, physical fatigue, reduced activity and mental fatigue) two months postmyocardial infarction with baseline measurements (first week in hospital), the results showed that levels of fatigue dimensions had decreased. In comparisons with levels of fatigue four months postmyocardial infarction in a reference group, we found lower levels of fatigue two months postmyocardial infarction.

CONCLUSION

The present findings indicated that postmyocardial infarction fatigue is lowest two months postmyocardial infarction. This may thus be the right time to identify persons experiencing postmyocardial infarction fatigue, as timely fatigue relief support may prevent progression into a state of higher levels of fatigue.

RELEVANCE TO CLINIC PRACTICE

Measuring fatigue two months postmyocardial infarction would enable healthcare professionals to identify persons experiencing fatigue and to introduce fatigue relief support. Tailored rehabilitation support should include stress management and breathlessness relief support. If maladaptive use of the coping strategies isolation and intrusion is observed, these strategies could be discussed together with the patient.

Does Illness Perception Predict Posttraumatic Stress Disorder in Patients with Myocardial Infarction?

INTRODUCTION

Myocardial infarction (MI) as a life-threatening event, carrying high risk of recurrence and chronic disabling complications, increases the risk of developing acute stress disorder (ASD), posttraumatic stress disorder (PTSD), or both. The aim of this study was to investigate the relationship between illness perceptions and having ASD, PTSD, or both in patients after MI.

METHOD

Seventy-six patients diagnosed with acute MI were enrolled into our prospective study. We evaluated patients during the first week and six months after MI. Patients were assessed by using the Clinician Administered PTSD Scale (CAPS), the Hamilton Depression Rating Scale (HDRS), the Hamilton Anxiety Rating Scale (HARS), the Brief Illness Perception Questionnaire (BIPQ), and a semi-structured interview for socio-demographic characteristics during both the first and second evaluations.

RESULTS

Acute stress disorder (ASD) developed in 9.2% of patients and PTSD developed in 11.9% of patients with MI. Illness perception factors of 'consequences, identity and concern' predicted the occurrence of both ASD and PTSD, whereas 'emotion' predicted only PTSD.

CONCLUSION

The factors of illness perceptions predicted the induction of ASD and PTSD in patients who had acute MI.

Matters of the heart: patients' adjustment to life following a cardiac crisis

In a sample of patients who experienced a myocardial infarction, coronary artery bypass graft surgery or both within the past year, we examined the extent to which patients' attempts to intrapersonally inhibit their emotions about their cardiac event and their attempts to disclose their feelings about the event to their partner predicted their psychological health (depression, anxiety, post-traumatic stress) and relational functioning (closeness, satisfaction). The more patients inhibited their feelings about their cardiac event, the poorer their psychological and relational functioning. Greater disclosure was associated with greater closeness to their partner. However, frequency of disclosure was also an indicator of level of distress, such that the more frequently patients talked about their feelings regarding the cardiac event with their partner, the more they had anxiety and post-traumatic stress symptoms. Important interactions of inhibition by disclosure on outcomes as well as moderation by time since the cardiac event were found and are discussed in greater detail.

Posttraumatic stress disorder prevalence and risk of recurrence in acute coronary syndrome patients: a meta-analytic review

BACKGROUND

Acute coronary syndromes (ACS; myocardial infarction or unstable angina) can induce posttraumatic stress disorder (PTSD), and ACS-induced PTSD may increase patients' risk for subsequent cardiac events and mortality.

OBJECTIVE

To determine the prevalence of PTSD induced by ACS and to quantify the association between ACS-induced PTSD and adverse clinical outcomes using systematic review and meta-analysis.

DATA SOURCES

Articles were identified by searching Ovid MEDLINE, PsycINFO, and Scopus, and through manual search of reference lists.

METHODOLOGY/PRINCIPAL FINDINGS

Observational cohort studies that assessed PTSD with specific reference to an ACS event at least 1 month prior. We extracted estimates of the prevalence of ACS-induced PTSD and associations with clinical outcomes, as well as study characteristics. We identified 56 potentially relevant articles, 24 of which met our criteria (N = 2383). Meta-analysis yielded an aggregated prevalence estimate of 12% (95% confidence interval [CI], 9%-16%) for clinically significant symptoms of ACS-induced PTSD in a random effects model. Individual study prevalence estimates varied widely (0%-32%), with significant heterogeneity in estimates explained by the use of a screening instrument (prevalence estimate was 16% [95% CI, 13%-20%] in 16 studies) vs a clinical diagnostic interview (prevalence estimate was 4% [95% CI, 3%-5%] in 8 studies). The aggregated point estimate for the magnitude of the relationship between ACS-induced PTSD and clinical outcomes (ie, mortality and/or ACS recurrence) across the 3 studies that met our criteria (N = 609) suggested a doubling of risk (risk ratio, 2.00; 95% CI, 1.69-2.37) in ACS patients with clinically significant PTSD symptoms relative to patients without PTSD symptoms.

CONCLUSIONS/SIGNIFICANCE

This meta-analysis suggests that clinically significant PTSD symptoms induced by ACS are moderately prevalent and are associated with increased risk for recurrent cardiac events and mortality. Further tests of the association of ACS-induced PTSD and clinical outcomes are needed.

Posttraumatic stress disorder following myocardial infarction: personality, coping, and trauma exposure characteristics

OBJECTIVE

This study aimed to investigate the interrelationship between trauma exposure characteristics of myocardial infarction (MI), MI patients' personality traits, coping strategies, post-MI PTSD, and general psychological distress.

METHOD

One hundred and twenty MI patients were recruited from two general practices. The MI patients were interviewed using a MI experience questionnaire and completed the Posttraumatic Stress Diagnostic Scale (PDS), the General Health Questionnaire-28 (GHQ-28), the NEO-Five Factor Inventory (NEO-FFI), and the COPE Scale.

RESULTS

Neuroticism was directly associated with post-MI PTSD and general psychological distress, while agreeableness did not link to the outcomes directly. Neuroticism influenced MI exposure characteristics which in turn influenced PTSD. Agreeableness affected PTSD and general psychological distress through MI exposure characteristics. Neuroticism influenced problem-focused coping which in turn affected general psychological distress. Agreeableness influenced problem-focused coping which in turn affected PTSD and general psychological distress.

CONCLUSIONS

Patients developed PTSD and general psychological distress following MI. Neurotic and antagonistic personality traits combined with patients' subjective experiences of MI and usage of problem-focused coping influenced the severity of outcomes.

Risk indicators for post-traumatic stress disorder in adolescents exposed to the 5.12 Wenchuan earthquake in China

In Chinese adolescents exposed to the Wenchuan earthquake, we used the Children's Revised Impact of Event Scale (CRIES) as the screening tool, and Post-traumatic Cognitions Inventory (PTCI) and the Social Support Rating Scale (SSRS) were used to assess the cognitive status and their social supports, to evaluate the prevalence and the predictors variables of post-traumatic stress disorder (PTSD) after the Wenchuan earthquake in China, which occurred on 12 May 2008. Subjects with a CRIES score greater than 30 were interviewed and assessed using the DSM-IV criteria for PTSD diagnosis by a trained psychiatrist with the Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children Lifetime version (Kiddie-SADS-L). We found the overall prevalence of PTSD was 2.5% in 3208 adolescents from the surrounding areas of the epicentre 6months after the earthquake. Risk factors for post-traumatic stress symptoms are as follows: being female, being buried/injured during the earthquake, having parents who were severely injured, having classmate(s) who died, having a house destroyed, and witnessing someone buried/wounded/dying during the earthquake. Individuals with better social support had significantly lower scores on the CRIES. There were significant differences in cognitive style between individuals at low risk for PTSD (CRIES<30) and those at high risk for PTSD (CRIES≥30). Post-traumatic cognition emerged as an important factor that was associated with PTSD reactions in children. Social support can lessen the impact of a natural disaster by affecting post-traumatic cognition.

Distress related to myocardial infarction and cardiovascular outcome: a retrospective observational study

BACKGROUND

During acute coronary syndromes patients perceive intense distress. We hypothesized that retrospective ratings of patients' MI-related fear of dying, helplessness, or pain, all assessed within the first year post-MI, are associated with poor cardiovascular outcome.

METHODS

We studied 304 patients (61 ± 11 years, 85% men) who after a median of 52 days (range 12-365 days) after index MI retrospectively rated the level of distress in the form of fear of dying, helplessness, or pain they had perceived at the time of MI on a numeric scale ranging from 0 ("no distress") to 10 ("extreme distress"). Non-fatal hospital readmissions due to cardiovascular disease (CVD) related events (i.e., recurrent MI, elective and non-elective stent implantation, bypass surgery, pacemaker implantation, cerebrovascular incidents) were assessed at follow-up. The relative CVD event risk was computed for a (clinically meaningful) 2-point increase of distress using Cox proportional hazard models.

RESULTS

During a median follow-up of 32 months (range 16-45), 45 patients (14.8%) experienced a CVD-related event requiring hospital readmission. Greater fear of dying (HR 1.21, 95% CI 1.03-1.43), helplessness (HR 1.22, 95% CI 1.04-1.44), or pain (HR 1.27, 95% CI 1.02-1.58) were significantly associated with an increased CVD risk without adjustment for covariates. A similarly increased relative risk emerged in patients with an unscheduled CVD-related hospital readmission, i.e., when excluding patients with elective stenting (fear of dying: HR 1.26, 95% CI 1.05-1.51; helplessness: 1.26, 95% CI 1.05-1.52; pain: HR 1.30, 95% CI 1.01-1.66). In the fully-adjusted models controlling for age, the number of diseased coronary vessels, hypertension, and smoking, HRs were 1.24 (95% CI 1.04-1.46) for fear of dying, 1.26 (95% CI 1.06-1.50) for helplessness, and 1.26 (95% CI 1.01-1.57) for pain.

CONCLUSIONS

Retrospectively perceived MI-related distress in the form of fear of dying, helplessness, or pain was associated with non-fatal cardiovascular outcome independent of other important prognostic factors.

Associations between organizational and incident factors and emotional distress in emergency ambulance personnel

OBJECTIVES

This study examined the prevalence and correlates of post-traumatic stress disorder (PTSD), anxiety and depression among emergency ambulance personnel.

DESIGN AND METHOD

A questionnaire and reminder were sent anonymously to 1029 emergency ambulance personnel in a large ambulance service.

RESULTS

Among the 617 respondents, levels of PTSD symptoms did not differ according to grade, but men had a higher prevalence rate than women. Key predictors of the severity of symptoms were organizational stress, the frequency of experiencing potentially traumatic incidents, length of service, and dissociation in response to an index incident. The degree of organizational, but not incident-related, stress discriminated between 'cases' and 'non-cases'. Nine and 23% of recorded scores indicated clinical levels of depression and anxiety respectively. Several work factors were associated with these emotions, explaining 38% of anxiety and 31% of depression scores.

CONCLUSION

Both organizational and individually based interventions may be necessary to minimize PTSD and other emotional disorders among ambulance personnel.

Stress-related symptoms and positive emotions after a myocardial infarction: a longitudinal analysis

BACKGROUND

There is a controversy as to whether the diagnostic umbrella of post-traumatic stress reactions is directly applicable to serious health conditions like myocardial infarction (MI).

OBJECTIVE

The principal objective of this study was to examine longitudinally the prevalence of posttraumatic stress-related symptoms, throughout three measurement periods, for patients who had suffered a first MI. In addition to the analysis of symptoms related to stress and general distress, the presence of and temporary evolution of positive emotions and optimism in these patients was also evaluated.

DESIGN

A longitudinal study with three periods of evaluation after the MI (Time 1 (T1): 48-72 hours, Time 2 (T2): 5 months, and Time 3 (T3): 13 months).

RESULTS

In T1 few symptoms related to the stressful event were found. The probable prevalence of PTSD was 8-11% at 5 months after the MI and 0-3% 13 months after the event. With regard to subjective severity of the infarction, although in the first instance patients did not regard the event as excessively traumatic, in the periods T2 and T3 this perception increased significantly [F (2, 32)=20.00; p=0.0001]. At all times during the measurement period the mean positive affect was significantly greater than the negative affect.

CONCLUSIONS

As the results show, the probable prevalence of PTSD, as well as the severity of different symptom clusters, is low at all times of the evaluation. The diagnostic implications of these findings are discussed as well as the uses and abuses of diagnostic labels to characterize the psychological experiences lived through after a potentially life-threatening health problem.

Post-traumatic stress disorder following myocardial infarction: prevalence and risk factors

BACKGROUND

Post-traumatic stress disorder (PTSD) is associated with negative impacts on physical health. Victims of a myocardial infarction (MI) who develop PTSD may be particularly affected by these impacts due to their cardiovascular vulnerability. Post-traumatic reactions in this population are not well known.

OBJECTIVES

To examine the prevalence of PTSD after MI and its risk factors, and to validate a prediction model for PTSD symptoms.

METHODS

Patients hospitalized for MI (n=477) were recruited in three hospitals. The Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, and questionnaires concerning PTSD symptoms and general measures were administered to patients during hospitalization and at one-month follow-up.

RESULTS

Four per cent of the patients had PTSD and 12% had partial PTSD. The perception of a threat to life, the intensity of acute stress disorder and depression symptoms several days after the MI, a history of referral to a psychologist or psychiatrist, and female sex were risk factors for the intensity of PTSD symptoms in a sequential multiple regression analysis (R=0.634). The prediction model was validated by applying the regression equation to 48 participants who were not included in the initial regression (R=0.633).

CONCLUSIONS

The risk factors for development of PTSD symptoms identified in the present study could be used to facilitate the detection of patients at risk for developing PTSD symptoms so they can later be offered psychological interventions as needed.

Incidence of posttraumatic stress disorder (PTSD) after myocardial infarction (MI) and predictors of ptsd symptoms post-MI--a brief report

OBJECTIVES

The objectives of this pilot study were to determine the incidence of Posttraumatic Stress Disorder (PTSD) one to two months after Myocardial Infarction (MI), and to evaluate potential predictors of PTSD symptoms post-MI.

METHODS

A convenience sample of 31 patients hospitalized for treatment of acute MI was interviewed during hospitalization and one to two months later. The assessments included socio-demographic questions, questions related to clinical history and hospitalization, assessment of depressive symptoms using the Center for Epidemiologic Studies-Depression (CES-D) scale, medical comorbidity using the Charlson Comorbidity Index (CCI), and perceived social support using the Medical Outcomes Study (MOS) scale. Medical records were reviewed for collection of clinical data. Symptoms of PTSD were evaluated using the Structured Clinical Interview for DSM-IV (SCID) and the Impact of Events Scale-Revised (IES-R).

RESULTS

While one patient (4.0%) met DSM IV criteria for PTSD; additional 16% of the patients had significant symptoms of PTSD as measured by the IES-R (scoring above 24). Higher scores of PTSD symptoms were significantly associated (p < 0.05) with younger age, black race, depressive symptoms in baseline, and self-reported anxiety during the MI.

CONCLUSIONS

The incidence of PTSD following MI was low, but 16% of MI patients developed subsyndromal PTSD. The emotional status of the patients at the time of the MI and their subjective reaction to the event were important factors in the development of PTSD symptoms. Black and younger patients were in increased risk of developing PTSD symptoms post-MI.

Acute stress disorder after myocardial infarction: prevalence and associated factors

OBJECTIVE

To examine the prevalence of acute stress disorder (ASD) after a myocardial infarction (MI) and the factors associated with its development.

METHODS

Of 1344 MI patients admitted to three Canadian hospitals, 474 patients did not meet the inclusion criteria and 393 declined participation in the study; 477 patients consented to participate in the study. A structured interview and questionnaires were administered to patients 48 hours to 14 days post MI (mean +/- standard deviation = 4 +/- 2.73 days).

RESULTS

Four percent were classified as having ASD using the Structured Clinical Interview for DSM-IV, ASD module. The presence of symptoms of depression (Beck Depression Inventory; odds ratio (OR) = 29.92) and the presence of perceived distress during the MI (measured using the question "How difficult/upsetting was the experience of your MI?"; OR = 3.42, R(2) = .35) were associated with the presence of symptoms of ASD on the Modified PTSD Symptom Scale. The intensity of the symptoms of depression was associated with the intensity of ASD symptoms (R = .65). The models for the detection and estimation of ASD symptoms were validated by applying the regression equations to 72 participants not included in the initial regressions. The results obtained in the validation sample did not differ from those obtained in the initial sample.

CONCLUSIONS

The symptoms of depression and the subjective distress during the MI could be used to improve the detection of ASD.

Persistence of posttraumatic stress symptoms 12 and 36 months after acute coronary syndrome

OBJECTIVES

To assess the prevalence and predictors of posttraumatic stress symptoms in patients at 12 and 36 months post hospital admission for an acute coronary syndrome (ACS). There is increasing recognition that posttraumatic stress may develop in the aftermath of an acute cardiac event. However, there has been little research on the longer-term prevalence of posttraumatic stress disorder (PTSD).

METHODS

Posttraumatic stress symptoms were assessed at 12 months in 213 patients with ACS and in 179 patients at 36 months. Predictor variables included clinical, demographic, and emotional factors measured during hospital admission.

RESULTS

At 12 months post ACS, 26 (12.2%) patients qualified for a diagnosis of PTSD; 23 (12.8%) patients were identified with PTSD at 36 months. Posttraumatic symptoms at 12 months were associated with younger age, ethnic minority status, social deprivation, cardiac symptom recurrence, history of depression, depressed mood during admission, hostility, and Type D personality. In multiple regression, depressed mood during admission and recurrent cardiac symptoms were independent predictors of posttraumatic symptoms (R(2) = 0.507, p < .001). At 36 months, posttraumatic stress symptoms were independently predicted by posttraumatic symptom levels at 12 months and depressed mood during admission (R(2) = 0.635, p < .001).

CONCLUSION

Posttraumatic stress symptoms persist for at least 3 years after an acute cardiac event. Early emotional responses are important in predicting longer-term posttraumatic stress. It is important to identify patients at risk for posttraumatic stress as they are more likely to experience reduced quality of life.

Psychological correlates of PTSD symptoms following stroke

This study assessed associations between a number of demographic, medical and psychological risk factors and post-traumatic stress disorder (PTSD) symptoms following stroke. Individuals (N = 102) who had experienced a stroke within the previous year participated in the study. Participants completed questionnaires containing measures of PTSD symptoms and a range of psychological risk factors (i.e., anxiety, depression, negative affect, dissociation, cognitive appraisals). Regression analyses revealed the variables under consideration were able to explain large proportions of the variance in the number (R(2) = .54, p < 0.001) and severity (R(2) = .58, p < 0.001) of PTSD symptoms. Number of strokes, negative affect and cognitive appraisals emerged as significant predictors of both the number and severity of PTSD symptoms. The present findings suggest that a significant proportion of stroke patients may benefit from the detection and treatment of PTSD symptoms.

Comorbidity and personality traits in patients with different levels of posttraumatic stress disorder following myocardial infarction

More research is needed to further our understanding of posttraumatic stress responses and comorbidity following myocardial infarction (MI), and to help us identify more clearly the personality traits which indicate that a person is more prone to developing post-MI posttraumatic stress disorder (PTSD). This study aimed to 1) investigate the comorbidity of patients who suffered from different levels of posttraumatic stress disorder following myocardial infarction (i.e. post-MI PTSD), and 2) investigate to what extent patients with different levels of post-MI PTSD differed in their personality traits. One hundred and twenty MI patients from two general practices were recruited for the study. They were asked to complete the Posttraumatic Stress Diagnostic Scale (PDS), the General Health Questionnaire-28 (GHQ-28) and the NEO-Five Factor Inventory (NEO-FFI). They were divided into a no-PTSD group, a partial-PTSD group and a full-PTSD group, according to the scores of the PDS. One hundred and sixteen members of the general public were also recruited for comparison purposes. They were asked to complete the GHQ-28. The results showed that patients with full-PTSD reported significantly more somatic problems, anxiety, social dysfunction and depression than the other two patient groups and the control group. When age, bypass surgery, mental health problems before MI and angioplasty were controlled for, patients with full-PTSD also reported greater symptom severity of the four GHQ subscales than the other two patient groups. Patients with full-PTSD were significantly more neurotic than those with no-PTSD and partial-PTSD. Patients with full-PTSD were less agreeable than patients with no-PTSD. Regression analyses showed that personality did not moderate the relationship between PTSD and comorbidity. To conclude, following MI, those with full-PTSD tend to report more severe comorbidity than those who have not developed PTSD fully. The former can also be distinguished from the latter by virtue of their specific personality traits.

Posttraumatic stress disorder and general health problems following myocardial infarction (Post-MI PTSD) among older patients: the role of personality

OBJECTIVES

This study aimed to: (1) investigate the degree to which older MI patients experienced post-MI PTSD and general health problems, and to (2) identify the association between five personality traits, post-MI PTSD and general health problems among these older people.

METHODS

The sample comprised 96 older MI patients and were recruited from two general practices. They were interviewed using the Posttraumatic Stress Diagnostic Scale (PDS), the General Health Questionnaire-28 (GHQ-28) and the NEO-Five Factor Inventory (NEO-FFI). The control group comprised 92 older people who experienced no MI. They were assessed using the GHQ-28.

RESULTS

The older MI patients experienced hyperarousal the most, followed by avoidance and re-experiencing symptoms. PDS revealed that 30% had full PTSD. The older patients were conscientious and agreeable individuals. They were also somewhat extraverted and open to experience. They also showed traits of neuroticism. Controlling for bypass surgery, heart failure, previous mental health difficulties, angina and angioplasty, regression analyses showed that neuroticism predicted re-experiencing and avoidance symptoms and general health total. Neuroticism and less agreeableness predicted hyperarousal symptoms.

CONCLUSIONS

MI older patients could manifest PTSD symptoms and general health problems following their MI. Personality traits, particularly neuroticism and antagonism, played a role in the manifestation of these symptoms.

Myocardial infarction and post-traumatic stress disorder: frequency, outcome, and atherosclerotic mechanisms

BACKGROUND

Post-traumatic stress disorder (PTSD) may develop in the aftermath of an acute myocardial infarction (MI). Whether PTSD is a risk factor for cardiovascular disease (CVD) is elusive. The biological mechanisms linking PTSD with atherosclerosis are unclear.

DESIGN

A critical review of 31 studies in the English language pursuing three aims: (i) to estimate the prevalence of PTSD in post-MI patients; (ii) to investigate the association of PTSD with cardiovascular endpoints; and (iii) to search for low-grade systemic inflammatory changes in PTSD pertinent to atherosclerosis.

METHODS

We located studies by PubMed electronic library search and through checking the bibliographies of these sources.

RESULTS

The weighted prevalence of PTSD after MI was 14.7% (range 0-25%; a total of 13 studies and 827 post-MI patients). Two studies reported a prospective association between PTSD and an increased risk of cardiovascular readmission in post-MI patients and of cardiovascular mortality in combat veterans, respectively. In a total of 11 studies, patients with PTSD had increased rates of physician-rated and self-reported cardiovascular diseases. Various cytokines and C-reactive protein were investigated in a total of seven studies suggesting that PTSD confers a pro-inflammatory state.

CONCLUSIONS

Increasing evidence suggests that PTSD specifically related to MI develops considerably frequently in post-MI patients. More research is needed in larger cohorts applying a population design to substantiate findings suggesting PTSD is an atherogenic risk factor and to understand better the suspected behavioural and biological mechanisms involved.

Symptoms of posttraumatic stress disorder in patients who have had a myocardial infarction

Symptoms of posttraumatic stress disorder (PTSD) and risk factors for recurrent ischemia were evaluated in 65 survivors of a myocardial infarction (MI) at baseline and 6 months afterward. PTSD patients had more uncontrolled cardiovascular risk factors at baseline. Patients with PTSD (N=14) were offered trauma-focused cognitive-behavior treatment (CBT) plus a nonspecific intervention to improve adherence to medical recommendations. Adherence to aspirin improved in recipients of the nonspecific intervention (N=8); PTSD symptoms and cardiovascular risk improved in patients who received CBT (N=6). PTSD may be a treatable risk factor for poor post-MI outcome. Further research is needed to evaluate treatment options.

Posttraumatic stress disorder in medically ill patients: what is known, what needs to be determined, and why is it important?

Can a medical illness or its treatment qualify as an emotionally traumatic event and can it cause posttraumatic stress disorder symptoms? If so, can the view of a medical illness as a traumatic experience enhance our ability to understand patients' adjustment to illness and their emotional reactions to it? Is it important to identify posttraumatic symptoms and try to address them in medically ill patients? These questions form the backbone for this review. Because many questions remain unanswered (or the answers are not definitive yet), we concisely summarize the issues and present our own view of the most pressing questions for further research.

The relationship between anxiety disorders and physical disorders in the U.S. National Comorbidity Survey

Although depression has clearly been shown to be associated with physical disorders, few studies have examined whether anxiety disorders are independently associated with medical conditions after adjusting for comorbid mental disorders. We examined the relationship between anxiety disorders and a wide range of physical disorders in a nationally representative sample. Data came from the National Comorbidity Survey (N=5,877, range=age 15-54 years, response rate=82.4%). The Composite International Diagnostic Interview [Kessler et al., 1998] was used to make DSM-III-R [American Psychiatric Association, 1987] mental disorder diagnoses. Physical disorders were assessed based on a list of several conditions shown to respondents. All analyses utilized multiple logistic regression to examine the relationship between past-year anxiety disorder diagnosis and past-year chronic physical disorder. Anxiety disorders were positively associated with physical disorders even after adjusting for mood disorders, substance-use disorders, and sociodemographics. Among respondents with one or more physical disorders, a comorbid anxiety disorder diagnosis was associated with an increased likelihood of disability even after adjusting for severity of pain, comorbid mood, and substance use disorders. Among specific anxiety disorders, posttraumatic stress disorder, panic attacks, and agoraphobia were more likely to be associated with specific physical disorders than generalized anxiety disorder, social phobia, or simple phobia. There is a strong and unique association between anxiety disorders and physical disorders. Clinically, the presence of an anxiety disorder among patients with physical disorders may confer a greater level of disability.

Posttraumatic stress disorder in the wake of heart disease: prevalence, risk factors, and future research directions

BACKGROUND

There is increasing recognition that patients after a cardiac event may be at risk of posttraumatic stress disorder (PTSD). The present article reviews studies looking at PTSD as a sequel of heart disease with a focus on prevalence, risk factors, and future research directions.

METHODS

We conducted a search on PsychInfo and MEDLINE from 1980 to the present. Studies were included in the review if they looked at PTSD after a cardiac event, reported on the number of cases with PTSD, and had been published in English.

RESULTS

We identified 25 studies that fulfilled the inclusion criteria, of which 7 reported on the follow-up of previously published studies. The prevalence of PTSD after heart disease varied from 0% to 38% across studies. PTSD has been most rigorously researched after myocardial infarction with the best-powered studies finding a prevalence rate of 15%. Studies including control groups showed that cardiac patients were at risk of developing PTSD. Risk factors included sociodemographic and psychological characteristics and aspects related to the cardiac event.

CONCLUSION

Despite substantial heterogeneity in the methodology of studies and differences in prevalence across studies, this review indicates that subgroups of patients are at risk of PTSD after a cardiac event. Future studies investigating PTSD as a sequel of heart disease should be more systematic, use a prospective study design with multiple assessments, and include sufficiently large samples. PTSD should not be ignored as a sequel of heart disease, given preliminary evidence that PTSD may be associated with nonadherence with medication and an increased risk of clinical adverse events.

Relationship of Quality of Life and Perceived Control With Posttraumatic Stress Disorder Symptoms 3 to 6 Months After Myocardial Infarction

PURPOSE

This study examined whether psychological variables were associated with posttraumatic stress disorder (PTSD) symptoms 3 to 6 months after myocardial infarction.

METHODS

The sample included 52 patients with myocardial infarction. A structured interview was used to obtain information about PTSD symptoms, quality of life, and ratings of perceived control, danger, and predictability, as well as information about stressful events that occurred during hospitalization.

RESULTS

Four patients (7.7%) met criteria for the diagnosis of PTSD. Elevated PTSD scores were associated with poorer quality of life (r = -0.32 to -0.79). Lower perceived control was associated with higher PTSD symptom scores (r = -0.30 to -0.52). Finally, PTSD scores were significantly correlated with the number of times patients were readmitted to the hospital (r = 0.35-0.57).

CONCLUSIONS

Approximately 8% of patients experienced PTSD 3 to 6 months following MI. Increasing levels of PTSD symptoms were correlated with poorer quality of life. Perceived lack of control during the MI and multiple hospitalizations may be related to the severity of PTSD symptoms.

The Impact of Event Scale--Revised: evaluation of the subscales and correlations to psychophysiological startle response patterns in survivors of a life-threatening cardiac event: an analysis of 129 patients with an implanted cardioverter defibrillator

BACKGROUND

The aim of the present study was to examine the reliability and validity of the Impact of Event Scale-Revised (IES-R) with special emphasis on the evaluation of the hyperarousal subscale against a standardized psychophysiological measurement.

METHODS

A total of 129 survivors of a life-threatening cardiac event underwent a psychodiagnostic evaluation and a psychophysiological acoustic startle reflex (ASR) paradigm. The ASR assessed the magnitude and habituation of electromyogram (EMG) and skin conductance responses (SCR) in response to the delivery of 15 acoustic startle trials. Pearson correlation and factor analysis was used to measure reliability and construct validity. The hyperarousal subscale was validated against the ASR in terms of sensitivity and specificity mainly using receiver operating characteristic (ROC) curve analysis.

RESULTS

A high reliability was found for the intrusion and avoidance subscale (alpha>0.8); however, the hyperarousal subscale showed a weaker reliability (alpha=0.66). No avoidance item, one intrusion item but four hyperarousal items revealed higher correlations to another than its assigned subscale. The hyperarousal subscale was not able to discriminate sufficiently between patients with and without exaggerated startle reactions as indicated by ROC curves running near the diagonal line.

LIMITATIONS

The scores in all three subscales are lower compared to subjects traumatized by non-cardiac events.

CONCLUSIONS

Reliability and construct validity for the intrusion and avoidance subscale proved to be high but was only sufficient for the hyperarousal subscale. Moreover, the criterion validity of the hyperarousal subscale regarding psychophysiological measurements is arguable and indicates further investigations in this area.

Posttraumatic stress, nonadherence, and adverse outcome in survivors of a myocardial infarction

OBJECTIVE

Posttraumatic stress disorder (PTSD) symptoms have been reported in patients with coronary vascular disease, after the trauma of a myocardial infarction (MI). The effect of these symptoms on post-MI disease control has not been elucidated. We conducted a study that sought to determine whether PTSD symptoms post-MI are associated with increased likelihood of cardiovascular readmission and with nonadherence to treatment recommendations.

METHODS

Patients were recruited during a visit in a cardiology clinic 6 months post-MI and were followed for 1 year. Adherence to aspirin was measured by platelet thromboxane production (an indication of aspirin's effect). Medical outcome was measured as rate of admission due to cardiovascular causes during the follow-up period. Self-report measures of PTSD (Impact of Event Scale), Depression, and Global Distress (SCL-90-R) were administered at enrollment.

RESULTS

Seventy-three patients were studied. Above-threshold PTSD symptom scores at enrollment, but not depression or global distress scores, were significant predictors of nonadherence to aspirin and of an increased likelihood of cardiovascular readmission over the course of the following year.

CONCLUSIONS

PTSD symptoms predicted poor disease control in this cohort of MI survivors. The data suggest that screening MI survivors for symptoms of PTSD may be beneficial if this high-risk population is to be targeted for interventions.

Posttraumatic stress disorder in first-time myocardial infarction patients

OBJECTIVES

The objectives of this study were to investigate the prevalence of posttraumatic stress disorder in patients with a first myocardial infarction compared with a random sample of healthy controls and to determine variables associated with the disorder.

DESIGN

A questionnaire was distributed to 112 consecutive patients 4 to 6 weeks after infarction and to 115 healthy controls selected randomly from the general population. Objective clinical measures were obtained from the patients' medical records.

RESULTS

Twenty-five (22%) patients qualified for a diagnosis of posttraumatic stress disorder (PTSD) compared with 8 (7%) controls with patients being more than a three-fold (OR: 3.84; 95% CI: 1.65 to 8.94) risk of having the disorder. When adjusting for other variables, the risk was reduced to above a two-fold risk (OR: 2.71; 95% CI: 0.99-7.41). In patients and controls, depression and neuroticism were associated with a diagnosis of PTSD adjusting for other variables. In patients, anxiety was associated with a diagnosis of PTSD adjusting for other variables. Left ventricular ejection fraction and symptoms of angina pectoris were not related to a diagnosis of PTSD in the patient group.

CONCLUSIONS

Given that previous research has shown that persons with PTSD are at increased risk of cardiovascular diseases, cardiac patients with the disorder may be at a higher risk of recurrent cardiac events. Although longitudinal studies are needed to confirm such a relationship, this disorder should not be overlooked because of its potential role in reinfarctions and mortality.

Posttraumatic stress disorder following medical illness and treatment

Studies describing posttraumatic stress disorder (PTSD) as a result of physical illness and its treatment were reviewed. PTSD was described in studies investigating myocardial infarction (MI), cardiac surgery, haemorrhage and stroke, childbirth, miscarriage, abortion and gynaecological procedures, intensive care treatment, human immunodeficiency virus (HIV) infection, awareness under anaesthesia, and in a group of miscellaneous conditions. Cancer medicine was not included as it had been the subject of a recent review in this journal. Studies were reviewed in terms of the prevalence rates for PTSD, intrusive and avoidance symptoms, predictive and associated factors and the consequences of PTSD on healthcare utilization and outcome. There was considerable variability both in the study methodology and design and in the results. The highest prevalence rates were identified in patients treated in intensive care units (ICUs) and those with HIV infection. Irrespective of the physical illness, posttraumatic symptomatology is more common than PTSD caseness. Existing characteristics of the patient may well predispose individuals to the development of PTSD as do other factors such as poor social support and negative interactions with healthcare staff. Generally, the severity of the illness itself is not predictive of PTSD. Issues relating to sampling, attrition, diagnosis, the course of symptoms, aetiological pathways, and the consequences of the disorder are discussed. The presence of PTSD most probably influences the patient's use of healthcare resources and may affect their clinical outcome.

Posttraumatic stress responses in children with life-threatening illnesses

Posttraumatic stress symptoms have been reported in response to various serious medical illnesses in adults and children. Not surprisingly, posttraumatic stress is probably more common in response to acute, life-threatening, events that are related to the illness. Emerging data suggest that children often experience life-saving medical procedures as traumatic, which puts caretakers and medical personnel in the role of perpetrators for the children. Trauma symptoms are also reported as common and severe in caregivers. Both of these issues have been previously poorly understood and should be addressed in assessment and treatment. As with other traumatic events, developmental considerations, the nature and severity of the event itself, social supports, and premorbid exposure to negative life events are also important issues to consider in developing appropriate interventions. The importance of developing prevention and treatment for PTSD in medically ill children and adults includes increased morbidity and mortality (e.g., nonadherence to medications) and psychiatric sequelae and decreased quality of life. Obstacles to systematic study of a psychiatric intervention for this group include difficulties assessing multidrug regimens and cognitive treatment effects in this group. The relative stability of social supports and the potential use of preventive measures make this an attractive population for intervention. Clinicians and researchers are encouraged to work together to develop and use uniform screening and assessment methods that will help to identify cases and facilitate the multicenter trials that are vital to increasing knowledge in this patient population.
