Reducing emotional distress improves prognosis in coronary heart disease: 9-year mortality in a clinical trial of rehabilitation

Prevention of heart failure

PURPOSE OF REVIEW

Chronic heart failure imposes a significant health burden and remains a substantial and increasing problem despite advances in therapy. Hence, prevention of heart failure is a priority.

RECENT FINDINGS

Various risk factors have been identified that contribute to the development of heart failure. In this review, we will discuss the various recently reported clinical trials, epidemiological studies, meta-analyses, and subanalyses that have identified these risk factors and have provided evidence regarding the strategies to prevent heart failure.

SUMMARY

Heart failure is a costly, disabling, and potentially fatal disease. It is therefore important to incorporate the strategies for prevention of heart failure on the basis of the current available evidence into routine clinical practice.

Usefulness of type D personality in predicting five-year cardiac events above and beyond concurrent symptoms of stress in patients with coronary heart disease

Psychological stress and type D personality have been associated with adverse cardiac prognosis, but little is known about their relative effect on the pathogenesis of coronary heart disease (CHD). "Type D" refers to the tendency to experience negative emotions and to inhibit the expression of these emotions in social interactions. We investigated the relative effect of stress and type D personality on prognosis at 5-year follow-up. At baseline, 337 patients with CHD who participated in cardiac rehabilitation filled in the General Health Questionnaire (psychological stress) and the Type D personality scale. Patients were followed for 5 years. The end point was major adverse cardiac events, which were defined as a composite of cardiac death, myocardial infarction, and cardiac revascularization (coronary artery bypass grafting/percutaneous coronary intervention). There were 46 major adverse cardiac events at follow-up, including 4 deaths and 8 myocardial infarctions. Type D patients had an increased risk of death/infarction (odds ratio 4.84, 95% confidence interval 1.42 to 16.52, p = 0.01) compared with non-type D patients, independent of disease severity. Stress (p = 0.011) and type D (p = 0.001) were related to an increased risk of developing a major adverse cardiac event after adjusting for gender, age, and biomedical risk factors. Multivariate analysis yielded left ventricular ejection fraction < or =40%, no treatment with coronary artery bypass grafting, and type D personality (odds ratio 2.90, 95% confidence interval 1.42 to 5.92, p = 0.003) as independent predictors of major adverse cardiac events, whereas psychological stress was marginally significant (odds ratio 2.01, 95% confidence interval 0.99 to 4.11, p = 0.054). In conclusion, type D personality is a psychological factor that may optimize risk stratification in patients with CHD. Type D reflects more than temporary changes in general stress level because it predicted cardiac events after controlling for concurrent symptoms of stress.

Positive and negative affect within the realm of depression, stress and fatigue: the two-factor distress model of the Global Mood Scale (GMS)

BACKGROUND

The Global Mood Scale (GMS; [Denollet, J., 1993a. Emotional distress and fatigue in coronary heart disease: the Global Mood Scale (GMS). Psychol Med 23, 111-121., Denollet, J., 1993b. The sensitivity of outcome assessment in cardiac rehabilitation. J Consult Clin Psychol 61, 686-695.]) was originally developed as a measure of positive affect (PA) and negative affect (NA) in cardiac patients. The purpose of this study was to examine its two-factor affect model in the realm of stress, depression, and fatigue in working adults.

METHODS

Affect, stress, depression, and fatigue were assessed with validated questionnaires in a sample of 228 adults (49.6% male; mean = 41.4 +/- 9 years) from the working population.

RESULTS

The GMS PA and NA scales were internally consistent (Cronbach's alpha = .94 and alpha = .93, respectively), and correlated in the expected direction with their corresponding mood scales from the Positive and Negative Affect Schedule (PANAS). Factor analyses of the 40 mood terms comprising the GMS and PANAS yielded one common PA-dimension, but two NA-dimensions reflecting emotional exhaustion (GMS) and anxious apprehension (PANAS) as different components of the stress process. A relatively high mean NA score of the GMS suggested that these working adults perceived terms that refer to malaise/deactivation as being relevant to describe their negative affective status. The GSM-NA scale was related to stress, depression and fatigue while the GMS-PA scale was positively associated with quality of life.

LIMITATIONS

This study is based on a cross-sectional design.

CONCLUSIONS

The association between the PA (negative correlation) and NA (positive correlation) scales of the GMS and perceived stress, depressive symptoms, and fatigue supports the validity of its two-factor model. Assessment of both PA and NA may benefit a better understanding of emotional distress in adults from the working population.

Predictors of poor mid-term health related quality of life after primary isolated coronary artery bypass grafting surgery

OBJECTIVE

To assess the determinants of poor mid-term health related quality of life (HRQoL) at one year after primary isolated coronary artery bypass grafting (CABG).

METHODS

463 patients who underwent primary isolated CABG for multivessel disease and came for their annual follow up at the outpatient clinic during one year at Harefield Hospital, Middlesex, were approached to participate in the present study. Prospective clinical data were collected as part of the clinical care of the patients and were retrospectively analysed when the patients consented to participate in the study at their outpatient visit. After their consent they were given three HRQoL assessment questionnaires. Scores, together with clinical data, were analysed by both univariate and multivariate analyses with regard to poor HRQoL outcome.

RESULTS

437 (94.4%) patients consented to participate in the study and filled in the HRQoL questionnaires. Ten variables were identified in the univariate analysis as potential predictors of poor scores of the physical element of HRQoL; however, only three variables-gastrointestinal problems, congestive heart failure, and type D personality trait-predicted poor physical scores independently. Eleven variables were identified in the univariate analysis as potential predictors of poor scores of the mental element of HRQoL; however, only three variables-peripheral vascular disease, infective complications, and type D personality trait-predicted poor physical scores independently.

CONCLUSION

Preoperative gastrointestinal problems, preoperative congestive heart failure, and type D personality trait were independent predictors of the poor physical component of HRQoL. Peripheral vascular disease, infective complications, and type D personality trait were independent predictors of the poor mental component of HRQoL. Interestingly, patients with type D personality were more than twice as likely to have poor physical HRQoL and more than five times as likely to have poor mental HRQoL.

Social inhibition modulates the effect of negative emotions on cardiac prognosis following percutaneous coronary intervention in the drug-eluting stent era†

AIMS

Negative emotions have an adverse effect on cardiac prognosis. We investigated whether social inhibition (inhibited self-expression in social interaction) modulates the effect of negative emotions on clinical outcome following percutaneous coronary intervention (PCI).

METHODS AND RESULTS

Eight hundred and seventy-five consecutive patients from the RESEARCH registry (Erasmus Medical Centre, Rotterdam) completed depression, anxiety, negativity (negative emotions in general), and social inhibition scales 6 months following PCI. The endpoint was major adverse cardiac event (MACE-death, myocardial infarction, coronary artery bypass graft (CABG), or PCI) at 9 months following assessment. There were 100 MACE; patients who were high in both negativity and inhibition were at increased risk of MACE (38/254=15%) when compared with high negativity/low inhibition patients (13/136=10%; P=0.018). Depression (P=0.23) or anxiety (P=0.63) did not explain away this moderating effect of inhibition. High negativity/high inhibition (HR=1.92, 95%CI 1.22-3.01, P=0.005) and previous CABG (HR=1.90, 95%CI 1.04-3.47, P=0.038) were independent predictors of MACE. Patients with high negativity but low inhibition were not at increased risk (P=0.76). High negativity/high inhibition also independently predicted death/MI (n=20) as a more specific endpoint (HR=5.85, P=0.001).

CONCLUSION

The interaction effect of social inhibition and negative emotions, rather than negative emotions per se, predicted poor clinical outcome following PCI. Social inhibition should not be overlooked as a modulating factor.

Quality of life in women following coronary artery bypass graft surgery

The purpose of this study was to determine the effect of coronary artery bypass graft (CABG) surgery on the quality of life of women. Wilson and Cleary's conceptual model of health-related quality of life, which examines five major outcomes (biological variables, symptom status, functional status, general health perceptions, perceived quality of life), was used. Participants included 61 women who provided information by self-report questionnaires before and three months after surgery. The major findings of the study are that women had significantly improved quality of life (p = .004) due to increased satisfaction with health and functioning (p < .001) at three months following CABG surgery. They experienced less angina (p < .001) and shortness of breath (p = .014), although fatigue was unrelieved for the majority of women. Psychological well being improved after surgery for most women (p < .001), with lower anxiety levels (p < .001), greater levels of well being (p = .021), feelings of health (p < .001) and vitality (p = .023). Women reported less use of emotive coping (p = .043), indicating less emotional distress. Nevertheless, 25% of the sample continued to experience severe psychological distress three months after surgery, indicating the need for continued follow-up.

Psychological distress and cardiovascular disease: results from the 2002 National Health Interview Survey

AIMS

The objective of this study was to examine the burden of psychological distress among individuals with different forms of heart disease in a large representative sample of adults.

METHODS AND RESULTS

Data were obtained from the 2002 National Health Interview Survey, which is a large annual survey of the US non-institutionalized civilian population. Psychological distress was assessed with a standardized questionnaire (K6) and heart disease diagnoses were based on self-report. Among non-diseased individuals, the estimated prevalence of psychological distress was 2.8%, whereas the estimates were 10, 6.4, and 4.1% among those with congestive heart failure (CHF), myocardial infarction (MI), and coronary heart disease (CHD), respectively. Over 1 million individuals with one or more of these conditions are estimated to experience psychological distress. However, only 31-35% of the participants with heart disease and psychological distress have visited a mental health professional. The logistic regression model results indicate that MI (OR 2.0, 95% CI 1.4-3.0) and CHF (OR 3.1, 95% CI 1.8-5.1) are significantly associated with psychological distress.

CONCLUSION

These findings imply that psychological distress is a significant comorbidity of cardiovascular disease. Other investigations have demonstrated a link between psychological distress and morbidity and mortality. Taken together, these findings provide the impetus for future investigations that assess the role that a medical and mental health care professional intervention may have in altering these outcomes when targeted at this distress.

DS14: standard assessment of negative affectivity, social inhibition, and Type D personality

OBJECTIVE

Type D personality-a joint tendency toward negative affectivity (NA) and social inhibition (SI)-is related to poor cardiac prognosis, but there is no standard for assessing Type D. This study reports on the Type D Scale-14 (DS14) as a standard measure of NA, SI, and Type D.

METHODS

The study included 3813 participants (2508 from the general population, 573 cardiac patients, 732 hypertension patients). They all filled out the DS14, containing 7-item NA and SI subscales; 275 subjects also completed the NEO-FFI, and 121 patients filled out the DS14 twice.

RESULTS

Factor analysis of the DS14 yielded 2 dominant traits; all of the NA and SI items loaded between 0.62 to 0.82 on their corresponding factor (N = 3678). The NA scale covered dysphoria, worry, and irritability; the SI scale covered discomfort in social interactions, reticence, and lack of social poise. The NA and SI scales were internally consistent (alpha = 0.88/0.86; N = 3678), stable over a 3-month period (test-retest r = 0.72/0.82) and not dependent on mood and health status (N = 121). NA correlated positively with neuroticism (r = 0.68); SI correlated negatively with extraversion (r = -0.59/-0.65). Scale-level factor analysis confirmed the construct validity of the DS14 against the NEO-FFI. Using a cutoff of 10 (NA > or =10 and SI > or =10), 1027 subjects (28%) were classified as Type D, 21% in the general population versus 28% in coronary heart disease and 53% in hypertension (p < or = .001). Age, sex, and Type D (odds ratio, 3.98; 95% confidence interval, 3.2-4.6; p <.0001) were independently associated with cardiovascular morbidity.

CONCLUSION

The DS14 is a brief, psychometrically sound measure of negative affectivity and social inhibition that could readily be incorporated in epidemiologic and clinical research.

Self-management interventions for chronic illness

An increasing number of interventions have been developed for patients to better manage their chronic illnesses. They are characterised by substantial responsibility taken by patients, and are commonly referred to as self-management interventions. We examine the background, content, and efficacy of such interventions for type 2 diabetes, arthritis, and asthma. Although the content and intensity of the programmes were affected by the objectives of management of the illness, the interventions differed substantially even within the three illnesses. When comparing across conditions, it is important to recognise the different objectives of the interventions and the complexity of the issues that they are attempting to tackle. For both diabetes and asthma, the objectives are concerned with the underlying control of the condition with clear strategies to achieve the desired outcome. By contrast, strategies to deal with symptoms of pain and the consequences of disability in arthritis can be more complex. The interventions that were efficacious provide some guidance as to the components needed in future programmes to achieve the best results. But to ensure that these results endure over time remains an important issue for self-management interventions.

The effect of low social support on short-term prognosis in patients following a first myocardial infarction

The objectives of the current study were (1) to assess adjustment in patients following a first myocardial infarction (MI) at 9 months compared with 4-6 weeks post-MI, (2) to examine the availability of and satisfaction with social support over time, and (3) to determine separate baseline psychosocial predictors of recurrent cardiac events. A questionnaire assessing post-traumatic stress disorder, anxiety, depression, health complaints, and social support, was distributed to consecutive patients 4-6 weeks and 9 months post-MI. Prior to assessment at follow-up, 8 (7%) of 112 patients had dropped out, and two had died due to cardiac causes. Objective clinical measures were obtained from medical records. There was an improvement in somatic and cognitive symptoms at follow-up, but no change in symptoms of arousal, depression, and anxiety. Half of the patients were afraid of a recurrent MI. There was a significant decrease in social support between baseline and follow-up, and lower social support at baseline was associated with a 10% increased risk of recurrent cardiac events at follow-up (OR: 0.90; 95% CI: 0.84 to 0.97) adjusting for all other variables. Some patients still experienced difficulties with psychosocial adjustment 9 months post-MI despite a reduction in somatic and cognitive symptoms. Social support decreased over time, which may have serious prognostic implications; lower social support at baseline was an independent predictor of recurrent events at 9 months. An important step for future research will be to investigate how social support can be enhanced in patients at risk.

Acute and chronic psychological stress in coronary disease

PURPOSE OF REVIEW

Coronary artery disease (CAD) is the leading cause of death in the United States and other developed countries. Along with a number of other factors thought to contribute to the high prevalence of CAD in developed societies (longer life expectancy, obesity, sedentary lifestyles), various psychological and social factors appear to promote the development or worsening of heart disease. It is well recognized that stress can be harmful to the cardiovascular system. The combination of the preexisting vulnerability and the major stressor are believed to result in cardiac arrhythmias and/or plaque rupture leading to death.

RECENT FINDINGS

Recently, the epidemiologic evidence of a link between stress and CAD is very convincing, yet the biopsychosocial pathway that would explain how stress can lead to disease is less clear. Different types of psychological stress have been found to be associated with increased cardiovascular events. Evidence regarding the efficacy of psychosocial interventions is also presented.

SUMMARY

It is suggested that, taken as a whole, evidence for a psychological and social impact on CAD morbidity and mortality is convincing.

Type D personality is associated with increased anxiety and depressive symptoms in patients with an implantable cardioverter defibrillator and their partners

OBJECTIVE

We investigated the prevalence of anxiety and depressive symptoms in patients with an implantable cardioverter defibrillator (ICD) and their partners, and the role of personality factors and social support as determinants of distress.

METHODS

Of all surviving patients (n = 221) having had an ICD implanted between October 1998 and January 2003, 182 patients and 144 partners completed the Hospital Anxiety and Depression Scale, the Type D Personality Scale, and the Perceived Social Support Scale. Type D personality defines those who tend to experience increased negative distress and who do not express these negative emotions in social interactions. Clinical variables for the patients were obtained from medical records.

RESULTS

Thirty-one percent of patients versus 42% of partners suffered from symptoms of anxiety (p =.048); symptoms of anxiety were particularly prevalent in male partners. Twenty-eight vs. 29% suffered from depressive symptoms (p =.901). In patients, Type D personality was independently related to anxiety (OR: 7.03; 95% CI: 2.32-21.32) and depressive symptoms (OR: 7.40; 95% CI: 2.49-21.94) adjusting for all other variables. Underlying cardiac disease pathology did not explain differences in patient distress. In partners, Type D personality was independently associated with increased symptoms of anxiety (OR: 8.77; 95% CI: 3.19-24.14) and depression (OR: 4.40; 95% CI: 1.76-11.01).

CONCLUSION

Partners experienced similar levels of depression but higher levels of anxiety compared with ICD patients. Personality was an important explanatory factor of distress in both ICD patients and their partners. Research is now warranted to investigate the implications of this finding for the clinical course of ICD patients, as Type D personality has been associated with adverse prognosis in patients with coronary artery disease.

Type D personality predicts death or myocardial infarction after bare metal stent or sirolimus-eluting stent implantation

OBJECTIVES

We investigated the effect of Type D personality on the occurrence of adverse events at nine months in patients with ischemic heart disease (IHD) after percutaneous coronary intervention (PCI) with sirolimus-eluting stents (SESs) or bare stents. Type D patients experience increased negative emotions and tend not to express these emotions in social interactions.

BACKGROUND

The SES is a new advent in interventional cardiology that reduces the restenosis rate and the risk of a major adverse cardiac event, but the SES has not been shown to confer any benefits on death or myocardial infarction (MI).

METHODS

Consecutive patients with IHD (n = 875) enrolled in the Rapamycin-Eluting Stent Evaluated At Rotterdam Cardiology Hospital (RESEARCH) registry completed the Type D Personality Scale (DS14) six months after PCI. The end point was a composite of death and MI. Events occurring before administration of the DS14 were excluded from analyses.

RESULTS

At nine months' follow-up, there were 20 events. Type D patients were at a cumulative increased risk of adverse outcome compared with non-Type D patients: 5.6% versus 1.3% (p < 0.002). Type D personality (odds ratio [OR] 5.31; 95% confidence interval [CI] 2.06 to 13.66) remained an independent predictor of adverse outcome adjusting for all other variables, including SES versus bare-stent implantation.

CONCLUSIONS

Type D personality was an independent predictor of adverse events in patients optimally treated with the latest advent in interventional cardiology. The DS14 could be used as a screening instrument in routine clinical practice to optimize risk stratification in IHD patients.

Role of spousal anxiety and depression in patients' psychosocial recovery after a cardiac event

OBJECTIVE

The purposes of this study were to a) compare emotional responses and perception of control of patients and their spouses to myocardial infarction or coronary revascularization; and b) examine the relationship between spouses' emotional distress and patients' emotional distress and psychosocial adjustment to the cardiac event.

METHODS

A total of 417 patient-spouse pairs were recruited after the patient was hospitalized for either acute myocardial infarction or coronary revascularization. We compared emotional responses of patients and spouses. The relationship between spouse anxiety and depression, and patient psychosocial distress was then determined.

RESULTS

Spouses had higher levels of anxiety (p <.001) and depression (p <.001) than did patients, but there were no differences in level of hostility. Patients also expressed higher levels of perceived control than did spouses (p <.001). Spouse anxiety, depression, and perceived control remained correlated with patient psychosocial adjustment to illness, even when patient anxiety and depression were kept constant. Patients' psychosocial adjustment to illness was worse when spouses were more anxious or depressed than patients, and it was best when patients were more anxious or depressed than spouses, whereas psychosocial adjustment to illness was intermediate to these 2 extremes when patient and spouse anxiety and depression levels were similar (p =.001).

CONCLUSION

Spouses often experience greater anxiety and depression and less perceived control than patients themselves. Attention to the psychological distress experienced by spouses of patients who have suffered a cardiac event may improve outcomes in patients.

Psychosocial treatment within sex by ethnicity subgroups in the Enhancing Recovery in Coronary Heart Disease clinical trial

OBJECTIVE

Intervening in depression and/or low perceived social support within 28 days after myocardial infarction (MI) in the Enhancing Recovery in Coronary Heart Disease (ENRICHD) clinical trial did not increase event-free survival. The purpose of the present investigation was to conduct post hoc analyses on sex and ethnic minority subgroups to assess whether any treatment subgroup is at reduced or increased risk of greater morbidity/mortality.

METHODS

The 2481 patients with MI (973 white men, 424 minority men, 674 white women, 410 minority women) who had major or minor depression and/or low perceived social support were randomly allocated to usual medical care or cognitive behavior therapy. Total mortality or recurrent nonfatal MI (ENRICHD primary endpoint) and cardiac mortality or recurrent nonfatal MI (secondary endpoint) were analyzed as composite endpoints by group for time to first event using Cox proportional hazards regression.

RESULTS

There was a trend in the direction of treatment efficacy for white men for the primary endpoint (hazard ratio [HR], 0.80; 95% confidence interval, 0.61-1.05; p =.10) and a significant (p <.006, Bonferroni corrected) effect for the secondary endpoint (HR, 0.63; 95% CI, 0.46-0.87; p =.004). In contrast, the HRs for each of the other three subgroups were nonsignificant. The magnitude of differences in treatment effects between white men and the other subgroups remained significant for the secondary endpoint (p =.04) after adjustment for age, education, living alone, antidepressant use, comorbidity score, cardiac catheterization, ejection fraction, history of hypertension, and major depression.

CONCLUSIONS

White men, but not other subgroups, may have benefited from the ENRICHD intervention, suggesting that future studies need to attend to issues of treatment design and delivery that may have prevented benefit among sex and ethnic subgroups other than white men.

Engaging patients in managing their cardiovascular health

Psychological factors play a major part in the impact, course, and treatment of cardiovascular disease. Patients' cognitions and emotions feed into their responses to their illness and its treatments and can, for example, affect the likelihood of attendance at cardiac rehabilitation programmes. It is important to view the rehabilitation process from the perspective of the patient and to examine and assess patients' beliefs. Self management and self efficacy need to be encouraged. Depression and anxiety are common after myocardial infarction and can influence outcome. A patient's mood state should be assessed routinely and regularly.

Is depression a major risk factor for coronary disease? A systematic review of the epidemiologic evidence

My objective is to examine systematically the status of the current evidence for and against depression as an independent major risk factor for coronary disease. From English-language reports on depression and coronary disease in MEDLINE (1966-2002) and PsycINFO (1967-2002), and from informal searches, I selected all studies that addressed the specific questions related to the established criteria for risk-factor status: (1) strength of association, (2) prediction, (3) specificity, (4) consistency, (5) dose-response effect, (6) biological plausibility, and (7) response to treatment. I find that the evidence for depression as a coronary disease risk factor is good for four criteria: strength of association, prediction, consistency, and dose-response effect. The evidence on specificity and biological plausibility is fair. Due to the lack of definitive studies, there is currently insufficient evidence for cardiac risk reduction in response to treatment for depression. My conclusion is that the evidence for depression's role as an independent major risk factor for coronary disease is good in four areas, but not yet conclusive in three, pointing to the need for three types of studies: (1) prospective, observational studies that address specificity questions, (2) studies of biological mechanisms linking depression and coronary disease, and (3) clinical trials of treatments for depression in people with coronary disease or at high risk for developing coronary disease.

Comparing symptoms of depression and anxiety as predictors of cardiac events and increased health care consumption after myocardial infarction

OBJECTIVES

We sought to compare symptoms of depression and anxiety as predictors of incomplete recovery after a first myocardial infarction (MI).

BACKGROUND

Depressive symptoms have been related to post-MI mortality and health care consumption, but little is known about the effect of anxiety. We wanted to examine the effect of emotional distress on health care consumption and whether depressive symptomatology is a better predictor of prognosis than anxiety.

METHODS

Subjects were 318 men (mean age 58 years) who completed the depression, anxiety, and hostility scales from the 90-item symptom check list after they survived a first MI.

RESULTS

After an average follow-up of 3.4 years, there were 25 cardiac events (fatal or non-fatal MI). Symptoms of both depression (hazard ratio [HR] 2.32, 95% confidence interval [CI] 1.04 to 5.18; p = 0.039) and anxiety (HR 3.01, 95% CI 1.20 to 7.60; p = 0.019) were associated with cardiac events, adjusting for age, left ventricular ejection fraction, and use of antidepressants. However, a multivariate analysis including all three negative emotions indicated that symptoms of anxiety (HR 2.79, 95% CI 1.11 to 7.03; p = 0.029) explained away the relationship between depressive symptoms and cardiac events. Regarding health care consumption, anxiety (OR 2.00, 95% CI 1.24 to 3.22; p = 0.005), but not depression/hostility, was a predictor of cardiac rehospitalization and frequent visits at the cardiac outpatient clinic.

CONCLUSIONS

Symptoms of depression and anxiety were associated with cardiac events. Anxiety was an independent predictor of both cardiac events and increased health care consumption and accounted for the relationship between depressive symptoms and prognosis. Symptoms of anxiety need to be considered in the risk stratification and treatment of post-MI patients.

Addressing patients' emotional and spiritual needs

BACKGROUND

A comprehensive, systematic literature review and original research were conducted to ascertain whether patients' emotional and spiritual needs are important, whether hospitals are effective in addressing these needs, and what strategies should guide improvement.

METHODS

The literature review was conducted in August 2002. Patient satisfaction data were derived from the Press Ganey Associates' 2001 National Inpatient Database; survey data were collected from 1,732,562 patients between January 2001 and December 2001.

RESULTS

Data analysis revealed a strong relationship between the "degree to which staff addressed emotional/spiritual needs" and overall patient satisfaction. Three measures most highly correlated with this measure of emotional/spiritual care were (1) staff response to concerns/complaints, (2) staff effort to include patients in decisions about treatment, and (3) staff sensitivity to the inconvenience that health problems and hospitalization can cause.

DISCUSSION

The emotional and spiritual experience of hospitalization remains a prime opportunity for QI. Suggestions for improvement include the immediate availability of resources, appropriate referrals to chaplains or leaders in the religious community, a team dedicated to evaluating and improving the emotional and spiritual care experience, and standardized elicitation and meeting of emotional and spiritual needs. Survey data suggested a focus on response to concerns/complaints, treatment decision making, and staff sensitivity.

Type D personality, cardiac events, and impaired quality of life: a review

BACKGROUND

Psychological distress has been associated with the pathogenesis and progression of coronary heart disease (CHD) but little is known about the determinants of distress as a coronary risk factor. Although it has become unfashionable to focus on personality factors since research on Type A behaviour yielded inconsistent findings, personality may comprise a major explanatory factor of individual differences in stress-related CHD. This article focuses on Type D--the distressed--personality, which describes patients who experience increased negative emotions and tend to inhibit the expression of these emotions in social interactions.

METHODS

The article reviews research on Type D personality in the context of CHD.

RESULTS

Accumulating evidence indicates that cardiac patients with the Type D personality are at increased risk for cardiovascular morbidity and mortality (odds ratios ranging from 4.1-8.9, P<0.0001) independent of standard cardiac risk factors. Type D patients are also at increased risk for psychological distress, clustering of psychosocial risk factors, impaired quality of life, and seem to benefit less from medical and invasive treatment. Preliminary evidence suggests that physiological hyper-reactivity and activation of pro-inflammatory cytokines may be responsible for the detrimental effect of Type D personality on cardiac prognosis.

CONCLUSIONS

There is an urgent need to adopt a personality approach in the identification of patients at risk for stress-related cardiac events. Type D is a stable personality construct that may be of special interest not only in CHD, but in other chronic cardiac conditions as well.

The psychological perspective: a professional view

Psychological issues surrounding the care of patients with cardiovascular disease are many and diverse. This paper discusses three main areas: cognitions, emotions, and social support. The examples given relate primarily to post-myocardial infarction patients but the concepts discussed are relevant to other aspects of cardiovascular disease. Patients' cognitions can influence early help seeking for symptoms of myocardial infarction, attendance at cardiac rehabilitation, behaviour change, and return to work. Depression and anxiety are common following myocardial infarction and can be associated with increased mortality. Mood changes must therefore be addressed as part of the cardiac rehabilitation programme. Social support also plays an important part in cardiac rehabilitation.

A mechanism converting psychosocial stress into mononuclear cell activation

Little is known about the mechanisms converting psychosocial stress into cellular dysfunction. Various genes, up-regulated in atherosclerosis but also by psychosocial stress, are controlled by the transcription factor nuclear factor kappaB (NF-kappaB). Therefore, NF-kappaB is a good candidate to convert psychosocial stress into cellular activation. Volunteers were subjected to a brief laboratory stress test and NF-kappaB activity was determined in peripheral blood mononuclear cells (PBMC), as a window into the body and because PBMC play a role in diseases such as atherosclerosis. In 17 of 19 volunteers, NF-kappaB was rapidly induced during stress exposure, in parallel with elevated levels of catecholamines and cortisol, and returned to basal levels within 60 min. To model this response, mice transgenic for a strictly NF-kappaB-controlled beta-globin transgene were stressed by immobilization. Immobilization resulted in increased beta-globin expression, which could be reduced in the presence of the alpha1-adrenergic inhibitor prazosin. To define the role of adrenergic stimulation in the up-regulation of NF-kappaB, THP-1 cells were induced with physiological amounts of catecholamines for 10 min. Only noradrenaline resulted in a dose- and time-dependent induction of NF-kappaB and NF-kappaB-dependent gene expression, which depended on pertussis-toxin-sensitive G protein-mediated phosphophatidylinositol 3-kinase, Ras/Raf, and mitogen-activated protein kinase activation. Induction was reduced by alpha(1)- and beta-adrenergic inhibitors. Thus, noradrenaline-dependent adrenergic stimulation results in activation of NF-kappaB in vitro and in vivo. Activation of NF-kappaB represents a downstream effector for the neuroendocrine response to stressful psychosocial events and links changes in the activity of the neuroendocrine axis to the cellular response.

Psychosocial influences on the development and course of coronary heart disease: current status and implications for research and practice

Psychosocial characteristics predict the development and course of coronary heart disease (CHD). In this review, the authors discussed human and animal research on psychophysiological mechanisms influencing coronary artery disease and its progression to CHD. They then reviewed literature on personality and characteristics of the social environment as risk factors for CHD. Hostility confers increased risk, and a group of risk factors involving depression and anxiety may be especially important following myocardial infarction. Social isolation, interpersonal conflict, and job stress confer increased risk. Psychosocial interventions may have beneficial effects on CHD morbidity and mortality, although inconsistent results and a variety of methodological limitations preclude firm conclusions. Finally, they discussed implications for clinical care and the agenda for future research.
