The psychology of men and women recovering from coronary artery bypass surgery

Validation of CARE Scale-7 in treatment-seeking patients with chronic pain: measurement of sex invariance

Supplemental Digital Content is Available in the Text.

The CARE Scale-7 is the first validated instrument to assess self-care difficulty in both sexes and may promote individualized care planning among chronic pain patients.

Objectives:

Social and interpersonal factors impact the trajectory of chronic pain. We previously developed and validated a 2-factor, 7-item measure to assess interpersonal factors, including relationship guilt and worry and difficulty prioritizing self-care in chronic pain. Here, we confirm the factor structure and examine the sex invariance of the two-factor structure of the CARE Scale-7.

Methods:

Data were collected as part of routine clinical care at a tertiary pain clinic using the Collaborative Health Outcomes Information Registry. Patient participants (67% women) were predominantly middle-aged (M = 50.9 years, SD = 17.8), married (55.2%), and White/non-Hispanic (55.7%). Data included demographics, pain characteristics, CARE Scale-7, pain catastrophizing, and Patient-Reported Outcomes Measurement Information System psychological and physical function measures. Confirmatory factor analysis was conducted to validate the factor structure of the CARE Scale, and a stepwise approach to measurement invariances by sex examined configural, metric, and scalar invariance.

Results:

Internal consistency of the scale items ensured suitability for factor analyses. Confirmatory factor analysis findings revealed an overall good fit of the 2-factor model among males and females and that CARE Scale-7 is in fact sex invariant. Finally, CARE Scale-7 showed convergent validity with pain-related outcomes.

Discussion:

The CARE Scale is the first validated instrument to assess self-care in both sexes among patients with chronic pain. The subscale of difficulty prioritizing self-care emerged as a potentially unique factor that should be integrated in clinical assessment. CARE Scale may facilitate standardized measurement in research and clinical contexts, which may inform a comprehensive treatment focus that integrates individualized self-care planning.

CARE Scale-7: Development and Preliminary Validation of a Measure to Assess Factors Impacting Self-Care in Chronic Pain

OBJECTIVES

Social and interpersonal factors may impact chronic pain self-care and self-management; however, no integrated measure exists to assess the interplay of these factors. We developed and tested a measure designed to assess salient interpersonal factors, including relationship guilt and worry, and difficulty prioritizing self-care in chronic pain.

METHODS

We tested self-report items broadly relevant to locus of care, limit-setting capacity, and worry/guilt about relationships in 3 discrete chronic pain samples (total N=1,452): (1) online sample of chronic pain clinic patients (N=729; 21 candidate CARE items, sociodemographics, and measures of psychological and physical functioning). Analytic results supported a final 7-item CARE scale that was next tested in (2) an anonymous online sample of 578 adults with chronic pain. (3) Finally, preliminary validation of the CARE scale was performed in a tertiary pain clinic sample (N=145).

RESULTS

Exploratory factor analysis revealed a 7-item, 2-factor solution (difficulty prioritizing self-care and guilt/worry) that accounted for a combined total of 58% of the variance. CARE scale-7 had modest convergent validity with pain intensity, pain-related interference, and emotional distress. Extreme difficulty with both factors was reported by about one-third of the total sample, suggesting that relationship factors significantly impact pain management and self-care.

DISCUSSION

Social factors are gaining attention for their influence on the trajectory of chronic pain. The CARE scale is a brief, integrated measure that may be used to reveal specific interpersonal and personal impediments to self-care, and identify important therapeutic targets to optimize self-management behaviors.

Psychological interventions for acute pain after open heart surgery

BACKGROUND

This is an update of a Cochrane review previously published in 2014. Acute postoperative pain is one of the most disturbing complaints in open heart surgery, and is associated with a risk of negative consequences. Several trials investigated the effects of psychological interventions to reduce acute postoperative pain and improve the course of physical and psychological recovery of participants undergoing open heart surgery.

OBJECTIVES

To compare the efficacy of psychological interventions as an adjunct to standard care versus standard care alone or standard care plus attention control in adults undergoing open heart surgery for pain, pain medication, psychological distress, mobility, and time to extubation.

SEARCH METHODS

For this update, we searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, Web of Science, and PsycINFO for eligible studies up to February 2017. We used the 'related articles' and 'cited by' options of eligible studies to identify additional relevant studies. We checked lists of references of relevant articles and previous reviews. We searched the ProQuest Dissertations and Theses Full Text Database, ClinicalTrials and the WHO International Clinical Trials Registry Platform to identify any unpublished material or ongoing trials. We also contacted the authors of primary studies to identify any unpublished material. In addition, we wrote to all leading heart centres in Germany, Switzerland, and Austria to check whether they were aware of any ongoing trials.

SELECTION CRITERIA

Randomised controlled trials comparing psychological interventions as an adjunct to standard care versus standard care alone or standard care plus attention in adults undergoing open heart surgery.

DATA COLLECTION AND ANALYSIS

Two review authors (SZ and SK) independently assessed trials for eligibility, estimated the risk of bias and extracted all data. We calculated effect sizes for each comparison (Hedges' g) and meta-analysed data using a random-effects model. We assessed the evidence using GRADE and created 'Summary of findings' tables.

MAIN RESULTS

We added six studies to this update. Overall, we included 23 studies (2669 participants).For the majority of outcomes (two-thirds), we could not perform a meta-analysis since outcomes were not measured, or data were provided by one trial only.No study reported data on the number of participants with pain intensity reduction of at least 50% from baseline. Only one study reported data on the number of participants below 30/100 mm on the Visual Analogue Scale (VAS) in pain intensity (very low-quality evidence). Psychological interventions did not reduce pain intensity in the short-term interval (g 0.39, 95% CI -0.18 to 0.96, 2 studies, 104 participants, low-quality evidence), medium-term interval (g -0.02, 95% CI -0.24 to 0.20, 4 studies, 413 participants, moderate-quality evidence) or in the long-term interval (g 0.05, 95% CI -0.20 to 0.30, 2 studies, 200 participants, moderate-quality evidence).No study reported data on median time to re-medication or on number of participants re-medicated. Only two studies provided data on postoperative analgesic use in the short-term interval, showing that psychological interventions did not reduce the use of analgesic medication (g 1.18, 95% CI -2.03 to 4.39, 2 studies, 104 participants, low-quality evidence). Studies revealed that psychological interventions reduced mental distress in the medium-term (g 0.37, 95% CI 0.13 to 0.60, 13 studies, 1388 participants, moderate-quality evidence) and likewise in the long-term interval (g 0.32, 95% CI 0.10 to 0.53, 14 studies, 1586 participants, moderate-quality evidence). Psychological interventions did not improve mobility in the medium-term interval (g 0.23, 95% CI -0.22 to 0.67, 3 studies, 444 participants, low-quality evidence), nor in the long-term interval (g 0.09, 95% CI -0.10 to 0.28, 4 studies, 458 participants, moderate-quality evidence). Only two studies reported data on time to extubation, indicating that psychological interventions reduced the time to extubation (g 0.56, 95% CI 0.08 to 1.03, 2 studies, 154 participants, low-quality evidence).Overall, the very low to moderate quality of the body of evidence on the efficacy of psychological interventions for acute pain after open heart surgery cannot be regarded as sufficient to draw robust conclusions.Most 'Risk of bias' assessments were low or unclear. We judged selection bias (random sequence generation) and attrition bias to be mostly low risk for included studies. However, we judged the risk of selection bias (allocation concealment), performance bias, detection bias and reporting bias to be mostly unclear.

AUTHORS' CONCLUSIONS

In line with the conclusions of our previous review, there is a lack of evidence to support or refute psychological interventions in order to reduce postoperative pain in participants undergoing open heart surgery. We found moderate-quality evidence that psychological interventions reduced mental distress in participants undergoing open heart surgery. Given the small numbers of studies, it is not possible to draw robust conclusions on the efficacy of psychological interventions on outcomes such as analgesic use, mobility, and time to extubation respectively on adverse events or harms of psychological interventions.

Perceptions and Experiences of Heart Disease: A Literature Review and Identification of a Research Agenda in Older Women

BACKGROUND

Following diagnosis of heart disease women have poorer health related outcomes compared with men. Nursing science lacks well-evaluated interventions to address the specific rehabilitative needs of older women with heart disease. This paper seeks to inform the development of nursing intervention studies by a review of published studies on the experiences and rehabilitative needs of older women with heart disease.

METHODS

The CINAHL, MEDLINE, FAMILY and PsychINFO databases were searched, identifying literature published from 1982 and written in English. Keywords used were women, old* (old, older) women, elderly women and: heart disease, heart failure, cardiac and rehabilitation. Hand searching of nursing and medical textbooks also occurred. These searches resulted in over 120 articles that met the criteria of describing experiences, perceptions, psychological responses and support rehabilitative needs of older women.

RESULTS

Older women present with symptoms that are different from those derived from a male-dominated research agenda and further there is a paucity of data related to evaluation of interventions tailored to the needs of women. Key themes emerging from the literature review include not only that older women compared with men have a poorer prognosis and experience greater disability moreover they: (1). are at a higher risk of psychosocial distress; (2). have a greater need for instrumental support and social support; (3). have an altered perception of risk; and (4). demonstrate the need for specific rehabilitation programs, tailored to their needs.

CONCLUSION

Future research should develop and evaluate intervention studies that better meet the unique needs of older women with heart disease. Particular emphasis needs to be on psychosocial aspects, given evidence that identify these are major concerns for women.

Psychological interventions for acute pain after open heart surgery

BACKGROUND

Acute postoperative pain is one of the most disturbing complaints in open heart surgery, and is associated with a risk of negative consequences. Several trials investigated the effects of psychological interventions to reduce acute postoperative pain and improve the course of physical and psychological recovery of participants undergoing open heart surgery.

OBJECTIVES

To compare the efficacy of psychological interventions as an adjunct to standard care versus standard care alone or standard care plus attention in adults undergoing open heart surgery on pain, pain medication, mental distress, mobility, and time to extubation.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2013, Issue 8), MEDLINE (1946 to September 2013), EMBASE (1980 to September 2013), Web of Science (all years to September 2013), and PsycINFO (all years to September 2013) for eligible studies. We used the 'related articles' and 'cited by' options of eligible studies to identify additional relevant studies. We also checked lists of references of relevant articles and previous reviews. We also searched the ProQuest Dissertations and Theses Full Text Database (all years to September 2013) and contacted the authors of primary studies to identify any unpublished material.

SELECTION CRITERIA

Randomised controlled trials comparing psychological interventions as an adjunct to standard care versus standard care alone or standard care plus attention in adults undergoing open heart surgery.

DATA COLLECTION AND ANALYSIS

Two review authors (SK and JR) independently assessed trials for eligibility, estimated the risk of bias and extracted all data. We calculated effect sizes for each comparison (Hedges' g) and meta-analysed data using a random-effects model.

MAIN RESULTS

Nineteen trials were included (2164 participants).No study reported data on the number of participants with pain intensity reduction of at least 50% from baseline. Only one study reported data on the number of participants below 30/100 mm on the Visual Analogue Scale (VAS) in pain intensity. Psychological interventions have no beneficial effects in reducing pain intensity measured with continuous scales in the medium-term interval (g -0.02, 95% CI -0.24 to 0.20, 4 studies, 413 participants, moderate quality evidence) nor in the long-term interval (g 0.12, 95% CI -0.09 to 0.33, 3 studies, 280 participants, low quality evidence).No study reported data on median time to remedication or on number of participants remedicated. Only one study provided data on postoperative analgesic use. Studies reporting data on mental distress in the medium-term interval revealed a small beneficial effect of psychological interventions (g 0.36, 95% CI 0.10 to 0.62, 12 studies, 1144 participants, low quality evidence). Likewise, a small beneficial effect of psychological interventions on mental distress was obtained in the long-term interval (g 0.28, 95% CI 0.05 to 0.51, 11 studies, 1320 participants, low quality evidence). There were no beneficial effects of psychological interventions on mobility in the medium-term interval (g 0.23, 95% CI -0.22 to 0.67, 3 studies, 444 participants, low quality evidence) nor in the long-term interval (g 0.29, 95% CI -0.14 to 0.71, 4 studies, 423 participants, low quality evidence). Only one study reported data on time to extubation.

AUTHORS' CONCLUSIONS

For the majority of outcomes (two-thirds) we could not perform a meta-analysis since outcomes were not measured, or data were provided by one trial only. Psychological interventions have no beneficial effects on reducing postoperative pain intensity or enhancing mobility. There is low quality evidence that psychological interventions reduce postoperative mental distress. Due to limitations in methodological quality, a small number of studies, and large heterogeneity, we rated the quality of the body of evidence as low. Future trials should measure crucial outcomes (e.g. number of participants with pain intensity reduction of at least 50% from baseline) and should focus to enhance the quality of the body of evidence in general. Altogether, the current evidence does not clearly support the use of psychological interventions to reduce pain in participants undergoing open heart surgery.

In Sickness and in Health: a Literature Review about Function of Social Support within Anxiety and Heart Disease Association

A narrative review of the major evidence concerning the relationship between anxiety, social support and cardiac disease was conducted. Literature demonstrates that a strict relationship between anxiety, social support and cardiac disease outcomes subsists. However, the function of social support within anxiety and heart disease association remains unclear and needs to further researches to be established. Moreover evidence suggests that it's the quality of close relationships to play an important role in affecting psychological and physiological health status. The main components that the literature suggests for a better quality of social support and close relationship, and the main assessment measure are presented. Evidence about cardiac rehabilitation programs and the need to assess and intervene on psychological and psychosocial factors is discussed.

Spiritual coping in rehabilitation- a comparative study: part 2

Spiritual coping, which may or may not contain religiosity, may enhance adaptation of clients with chronic illness. Part 1 of this article (Baldacchino et al, 2013) presented the research methodology of this cross-sectional comparative study, which explored the spiritual coping of clients with chronic illness receiving rehabilitation services in Malta (n=44) (lower limb amputation: n=10, chronic heart disease: n=9, osteoarthritis in an institution: n=10 and in the community: n=15) and Norway (n=16) (post-hip/shoulder surgery: n=5; chronic heart disease: n=5; chronic pain: n=6). Data were collected from seven purposive samples by focus groups. Roy's adaptation model (1984) and Neuman's Systems Model (2010) guided the study. Part2 discusses the findings, which consist of one main spiritual coping theme and three sub-themes: 'adopting religious coping strategies, relationship with God, and time for reflection and counting one's blessings'. Commonalities were found in the findings except in one dimension, which was found only in the Malta group, that is, being supported by others with a similar condition. This difference may be a result of the environment in the rehabilitation centres, cultural, and geographical differences between the two countries. While considering the limitations of this study, recommendations are proposed to the rehabilitation and education sectors and further trans-cultural comparative longitudinal research with mixed method approach on various clients with acute, chronic and life-threatening illness.

A systematic review of pre-operative predictors of post-operative depression and anxiety in individuals who have undergone coronary artery bypass graft surgery

In addition to the physical benefits, another important objective of coronary artery bypass graft (CABG) surgery is improvement of health-related quality of life. The aim of this systematic review is to provide an overview of the literature relating to the pre-operative prediction of post-operative depression and anxiety in individuals who have undergone CABG surgery. Forty-six studies were identified through a literature search of electronic databases conducted using explicit inclusion and exclusion criteria. The study characteristics, methodological features, and psychometric and clinical outcomes were summarised in a systematic manner. Collective appraisal of the studies indicated that symptoms of depression and anxiety exhibited after CABG surgery are best predicted by pre-operative measures of functioning in that area. Papers were inconclusive with respect to the predictive qualities of gender and age. Further research is required to clarify the predictive values of these and other factors, including pre-morbid ill health and socio-economic status. The findings of this review indicate a range of pre-operative predictors of post-operative depression and anxiety in patients with CABG. Chief among these are pre-operative depression and anxiety. These findings have clinical implications concerning the importance of pre and post-operative psychological assessment and intervention for individuals at risk of poor psychological recovery.

Telephone-delivered collaborative care for treating post-CABG depression: a randomized controlled trial

CONTEXT

Depressive symptoms commonly follow coronary artery bypass graft (CABG) surgery and are associated with less positive clinical outcomes.

OBJECTIVE

To test the effectiveness of telephone-delivered collaborative care for post-CABG depression vs usual physician care.

DESIGN, SETTING, AND PARTICIPANTS

Single-blind effectiveness trial at 7 university-based and community hospitals in or near Pittsburgh, Pennsylvania. Participants were 302 post-CABG patients with depression (150, intervention; 152, usual care) and a comparison group of 151 randomly sampled post-CABG patients without depression recruited between March 2004 and September 2007 and observed as outpatients until June 2008.

INTERVENTION

Eight months of telephone-delivered collaborative care provided by nurses working with patients' primary care physicians and supervised by a psychiatrist and primary care physician from this study.

MAIN OUTCOME MEASURES

Mental health-related quality of life (HRQL) measured by the Short Form-36 Mental Component Summary (SF-36 MCS) at 8-month follow-up; secondary outcome measures included assessment of mood symptoms (Hamilton Rating Scale for Depression [HRS-D]), physical HRQL (SF-36 PCS), and functional status (Duke Activity Status Index [DASI]); and hospital readmissions.

RESULTS

The intervention patients reported greater improvements in mental HRQL (all P < or = .02) (SF-36 MCS: Delta, 3.2 points; 95% confidence interval [CI], 0.5-6.0), physical functioning (DASI: Delta, 4.6 points; 95% CI, 1.9-7.3), and mood symptoms (HRS-D: Delta, 3.1 points; 95% CI, 1.3-4.9); and were more likely to report a 50% or greater decline in HRS-D score from baseline (50.0% vs 29.6%; number needed to treat, 4.9 [95% CI, 3.2-10.4]) than usual care patients (P < .001). Men with depression were particularly likely to benefit from the intervention (SF-36 MCS: Delta, 5.7 points; 95% CI, 2.2-9.2; P = .001). However, the mean HRQL and physical functioning of intervention patients did not reach that of the nondepressed comparison group.

CONCLUSION

Compared with usual care, telephone-delivered collaborative care for treatment of post-CABG depression resulted in improved HRQL, physical functioning, and mood symptoms at 8-month follow-up.

TRIAL REGISTRATION

The Bypassing the Blues treatment protocol: stepped collaborative care for treating post-CABG depression

OBJECTIVE

To present the design of the Bypassing the Blues (BtB) study to examine the impact of a collaborative care strategy for treating depression among patients with cardiac disease. Coronary artery bypass graft (CABG) surgery is one of the most common and costly medical procedures performed in the US. Up to half of post-CABG patients report depressive symptoms, and they are more likely to experience poorer health-related quality of life (HRQoL), worse functional status, continued chest pains, and higher risk of cardiovascular morbidity independent of cardiac status, medical comorbidity, and the extent of bypass surgery.

METHODS

BtB was designed to enroll 450 post-CABG patients from eight Pittsburgh-area hospitals including: (1) 300 patients who expressed mood symptoms preceding discharge and at 2 weeks post hospitalization (Patient Health Questionnaire (PHQ-9) >or=10); and (2) 150 patients who served as nondepressed controls (PHQ-9 <5). Depressed patients were randomized to either an 8-month course of nurse-delivered telephone-based collaborative care supervised by a psychiatrist and primary care expert, or to their physicians' "usual care." The primary hypothesis will test whether the intervention can produce an effect size of >or=0.5 improvement in HRQoL at 8 months post CABG, as measured by the SF-36 Mental Component Summary score. Secondary hypotheses will examine the impact of our intervention on mood symptoms, cardiovascular morbidity, employment, health services utilization, and treatment costs.

RESULTS

Not applicable.

CONCLUSIONS

This effectiveness trial will provide crucial information on the impact of a widely generalizable evidence-based collaborative care strategy for treating depressed patients with cardiac disease.

Longitudinal Risk Factors for Adverse Psychological Functioning Six Months after Coronary Artery Bypass Graft Surgery

This research aimed to identify modifiable risk factors for poor psychological functioning six months post-operatively, using a chronic illness model to explain the relationships between risk factors. Consecutive elective CABG patients ( N = 119) completed self-report measures including optimism, illness representations, self-rated health, social support, coping methods, depression, anxiety and PTSD symptomatology in a repeated measures design. Poor pre-operative psychological functioning was the strongest psychological risk factor for adverse psychological functioning six months post-operatively. Longitudinal support for the chronic illness model examined was limited. Further research to identify modifiable risk factors and pre-operative psychopathology screening to determine individuals at-risk of poor psychological outcome is recommended.

Physical, psychological and social recovery patterns after coronary artery bypass graft surgery: A prospective repeated measures questionnaire survey

AIM

This study examined the physical, psychological and social recovery patterns of Hong Kong Chinese patients who have undergone CABG surgery over a period of six months.

BACKGROUND

Recovery from coronary artery bypass graft (CABG) surgery is a dynamic process and the associated physical, psychological and social effects could lead to failure to recuperate leading to hospital re-admission and morbidity.

DESIGN

A prospective repeated measures design was used for this research. Patients were interviewed in person 5 days before surgery and at 1 week after discharge, and by telephone at 3 and 6 months after discharge. Physical recovery dimension was assessed by three categories of the Sickness Impact Profile (ambulation, sleep-rest, body movement and care). Social recovery dimension was assessed by three categories of the Sickness Impact Profile (SIP) (home management, social interaction, and recreation and pastimes). Psychological recovery was assessed using the Centre for Epidemiologic Studies-Depression (CES-D).

RESULTS

Sixty-eight patients participated in this research. The mean physical SIP-dimension score and depression level at discharge was the highest then gradually decreased at 6 months after CABG. The SIP-physical and SIP-social and depression level differed significantly across the four-assessment time within-group. There were no gender differences in physical and social recovery and depression levels. Patients who had poorer physical and social recovery had more depression at one week and three months after CABG surgery.

CONCLUSION

Patients should be prepared for discharge after CABG surgery. Cultural factors may have influenced the similar recovery patterns between genders. These factors contributing to early recovery must be further examined.

RELEVANCE TO CLINICAL PRACTICE

Because of the large number of patients who undergo CABG worldwide, and because of healthcare cost related to this intervention, it is important for both patients and healthcare providers to have realistic expectations about the recovery process and to recognise deviations from the norm. The results provided some insights into the Hong Kong Chinese patients' recovery from CABG surgery that would guide the development of culturally appropriate pre-operative and discharge teaching for this group of patients.

Stressors and Anxiety in Patients Undergoing Coronary Artery Bypass Surgery

Background Patients undergoing coronary artery bypass surgery who have increased anxiety levels have poorer outcomes than patients with lower levels, yet few studies have identified the concerns associated with this anxiety.

Objective To describe the concerns of patients undergoing coronary artery bypass surgery and to identify concerns that were associated with higher levels of anxiety.

Method Patients (n = 172) were interviewed to determine their concerns and anxiety levels before surgery, before discharge, and 10 days after discharge. Multiple regression was used to determine the predictors of anxiety.

Results Although individual concerns changed over time, anxiety levels did not change from before to after surgery, remaining low to moderate. Being female and having more concerns about waiting for the surgery, being in pain/discomfort, and resuming lifestyle were predictors of increased anxiety before surgery. Predictors of increased anxiety while hospitalized after the surgery included taking anxiolytic or antidepressant medications, higher anxiety levels before surgery, concerns about personal things being inaccessible, and difficulty sleeping. Patients with higher anxiety levels after discharge were older, more anxious before surgery, and had concerns about being in pain/discomfort.

Conclusion Patients waiting for coronary artery bypass surgery should be routinely assessed for anxiety before the procedure, and interventions to prevent or reduce anxiety should be provided. Interventions must be multifactorial, including information and support for pain management and realistic information about surgery schedules and resuming lifestyle after the surgery. Women and older patients may need to be targeted for intervention.

Rehabilitation and guidance as reported by women and men who had undergone coronary bypass surgery

AIMS AND OBJECTIVES

The purpose of this study was to describe the experience of rehabilitation reported by coronary artery disease patients who had undergone coronary artery bypass surgery. A further purpose was to describe the kind of guidance on rehabilitation that they were given during this period.

METHODS

The data consisted of thematic questionnaires completed by six women and eight men who had undergone coronary artery bypass surgery. They had recorded their experiences on these questionnaires at one-month intervals for a year after the surgery. The data were analysed using the method of content analysis.

RESULTS

On the basis of the results, women had experienced the most balanced period of physical, mental and social rehabilitation during the six months following surgery. Their recovery, however, suffered a setback after the first six months. On the basis of the results, men attained a better balance of physical, mental and social rehabilitation only after the six-month period following surgery. Even men had various problems in their rehabilitation, but their recovery proceeded more smoothly than that of women. Women hoped for more guidance throughout the process of rehabilitation. The support and help from wives had a positive impact on the process of men's recovery. Peer support was another significant source support.

CONCLUSIONS

A person undergoing rehabilitation needs special guidance from health care professionals, especially when his/her rehabilitation does not proceed optimally. The findings suggest that, especially, the guidance of women should be improved because women seemed to suffer from many problems during their process of rehabilitation, including loneliness, insecurity, uncertainty, fears, depression and anxiety.

RELEVANCE TO CLINICAL PRACTICE

Expanding the role of practical nurses to provide both preventive and rehabilitation guidance should be seen as an important strategy in health care. Individual needs, gender differences and support from families and peers should be taken into consideration when planning and implementing guidance.

Device Implant Technique and Consideration of Body Image: Specific Procedures for Implantable Cardioverter Defibrillators in Female Patients

OBJECTIVES

The purpose of this paper is to describe the psychological effects of implantable cardioverter defibrillator (ICD) implantation in female patients and to make clinical recommendations for providers to optimize health outcomes for women.

BACKGROUND

Traditional ICD implantation produces visible scarring. Changes in physical appearance affect body image in all ICD recipients but may be more onerous in female ICD recipients. Electrophysiologists have described cosmetic approaches to device placement that appear promising and may warrant consideration in female patients.

CONCLUSIONS

Active discussion and consideration of alternative device implant techniques are indicated in female patients. Female patients should also be given time to make preoperative decisions, and family members should be engaged in decision making. The investigation of cosmetic implants is noteworthy and could improve quality of life, adjustment, and psychological fitness of female ICD recipients.

Family support, living alone, and subjective health of a patient in connection with a coronary artery bypass surgery

OBJECTIVE

The study's objective was to evaluate the connections among family support, living alone, and subjective health after coronary artery bypass surgery (CABS).

DESIGN

This was a prospective and comparative follow-up study.

SETTING

The study took place in surgical clinics in two university hospitals in Finland.

PATIENTS

A total of 279 patients underwent CABS. The sample comprised consecutive patients who were willing to participate.

INTERVENTION

The patients were asked to evaluate their subjective health before surgery (initial phase) and 6 months after surgery (follow-up phase).

OUTCOME MEASURES

Outcome was measured by the Chest Pain and Dyspnea Scale, Modified Beck Depression Inventory, Endler Anxiety Scale, Family Support Scale, and Hopelessness items.

RESULTS

Subjective health improved significantly after CABS. Those who had lower family support before surgery had more depressive symptoms, anxiety, and hopelessness than those who had more support. In the group with low family support, the subjective health of women was poorer than that of men, and those who had no vocational education described poorer health than others. In the group with high family support, those who had no vocational education had more chest pain and dyspnea than others. Patients who were living alone had initially more depressive symptoms and hopelessness compared with patients living with someone. At follow-up, those living alone reported more chest pain and depressive symptoms than those living with someone. Patients aged less than 65 years and living alone reported more depressive symptoms, anxiety, and hopelessness than the oldest age group during the follow-up. In those patients living with someone, the subjective health of female patients, patients aged less than 65 years, and patients who had no vocational education was poorer than others.

CONCLUSIONS

High family support seemed to protect health and promote recovery. In nursing it is important to take care of those who receive only limited amount of family support or who live alone. These results suggest that women, patients aged less than 65 years, and patients with no vocational education may need additional support and care.

Validation of the Cardiac Depression Scale in a cardiac rehabilitation population

OBJECTIVE

The current study was undertaken to provide further evidence supporting the reliability and validity of the Cardiac Depression Scale (CDS) in a population of cardiovascular patients.

METHODS

The CDS was administered to 627 consecutive ambulatory adult cardiac patients attending an outpatient Cardiac Rehabilitation program, and a subgroup also completed the Geriatric Depression Scale--Short Form (GDS-SF).

RESULTS

Factor analysis revealed six subscales accounting for 62% of scale variance. The CDS demonstrated high internal consistency (Cronbach's alpha=.92) and correlation coefficient with the GDS-SF of .77. Receiver operating characteristic curves suggested a CDS cutoff score of 100 to detect more severe depression, and 90 to detect mild to moderate depression.

CONCLUSION

These findings encourage the continued use and evaluation of the CDS for measuring symptoms of depressive affect in cardiac patients.

Psychosocial predictors of cardiac rehabilitation quality-of-life outcomes

OBJECTIVE

This study investigated hostility, social support, coping, depression, and their contributions to concurrent and posttreatment quality of life (QoL) among a group of patients participating in a 6-week cardiac rehabilitation program.

METHOD

Both direct and mediational relationships among psychosocial factors, QoL baseline, and QoL outcome were examined using structural equation modeling analysis, while age, education, and severity of illness (risk for future event) were controlled.

RESULTS

The final model was well supported (chi(2)=64.88, df=56, P>.05; CFI=.99, RMSEA=.04). Results indicated that baseline QoL, hostility, and depressive symptom severity directly and independently predicted QoL outcome, while depression and hostility were also associated with baseline QoL. Hostility, social support, and maladaptive coping also contributed to baseline and follow-up QoL by their associations with depression.

CONCLUSION

Psychosocial characteristics were interrelated, and they predicted postrehabilitation QoL outcome directly or indirectly through depression symptom severity.

Fatigue and physical activity in older women after myocardial infarction

BACKGROUND

Within 6 years of a myocardial infarction (MI) more women (35%) than men (18%) will have another MI. Participation in physical activity is one of the most effective methods to reduce cardiac risks; however, few older women participate. One of the most frequently reported barriers to physical activity is fatigue.

OBJECTIVES

The specific aims of this study were to (1) describe factors related to fatigue in older women after MI and (2) examine the relationship of fatigue to physical activity in older women after MI.

METHODS

This descriptive correlational study examined the effects of age, body mass index, comorbidities, sleep, beta-blocker medication, depression, and social support on fatigue and physical activity in women (N = 84), ages 65 to 88 years old, 6 to 12 months post-MI. All women had their height and weight measured and completed (1) a health form on comorbidities, physical activity, and medication history; (2) the Geriatric Depression Scale; (3) the Epworth Sleepiness Scale; (4) the Revised Piper Fatigue Scale; and (5) the Social Provisions Scale.

RESULTS

The majority (67%) of the women reported fatigue that they perceived as different from fatigue before their MI. Moderately strong correlations were noted among depression, sleep, and fatigue, and multivariate analysis indicated that depression and sleep significantly accounted for 32.7% of the variance in fatigue. Although only 61% of the women reported participating in physical activity for exercise, most were meeting minimal kilocalories per week for secondary prevention. Fatigue was not significantly associated with participation in physical activity.

CONCLUSION

Describing correlates to fatigue and older women's participation in physical activity after MI are important to develop interventions targeted at increasing women's participation in physical activity, thus decreasing their risk for recurrent MIs.

Group-mediated activity counseling and traditional exercise therapy programs: Effects on health-related quality of life among older adults in cardiac rehabilitation

BACKGROUND

Regular physical activity has been consistently related to improvements in health- related quality of life (HRQL) in older adults. Nevertheless, systematic investigations of the influence of exercise therapy on older men and women enrolled in cardiac rehabilitation remain sparse.

PURPOSE

The primary purpose of this investigation was to compare the effects of a group-mediated cognitive behavioral physical activity intervention program (GMCB) to a traditional cardiac rehabilitation program (CRP) with regard to changes in HRQL in a community-dwelling sample of older adults.

METHODS

This randomized clinical trial assigned 147 participants who were eligible for inclusion in cardiac rehabilitation to the GMCB or traditional CRP arms. Changes in HRQL at 3 and 12 months were assessed using the Short Form-36 (SF-36) from the Medical Outcomes Study.

RESULTS

Mixed-model analyses yielded significant Baseline x Gender x Treatment interactions for the self-reported mental health component and the Vitality subscale of the SF-36. Decomposition of these interactions revealed that men in both exercise therapy groups and women in the GMCB treatment with low baseline values demonstrated more favorable improvements in the HRQL perceived mental health measures than women in the CRP treatment.

CONCLUSIONS

Improvements in HRQL among older adults enrolled in cardiac rehabilitation differ as a function of treatment, gender, and initial mental health status. Results are discussed in terms of the implications for the design of future physical activity interventions among older adults with cardiovascular disease and the measurement of their HRQL.

Independent and mediated contributions of personality, coping, social support, and depressive symptoms to physical functioning outcome among patients in cardiac rehabilitation

This study examined the direct and mediated contributions of psychosocial variables to posttreatment physical functioning among 142 patients receiving cardiac rehabilitation. Two models were proposed and tested. In the first model, psychosocial factors were correlated and made to predict baseline and 6-week physical functioning. The results showed that after controlling for age, illness severity, baseline physical functioning, and other psychosocial correlates, optimism and social support still significantly predicted better posttreatment physical functioning. In the second model, we explored both the direct and mediational relationships between psychosocial factors and physical health outcomes. Optimism and social support were found to contribute to health outcomes not only directly but also indirectly through the mediation of less engagement in detrimental coping and lower depressive symptoms, whereas hostility and negative coping only predicted outcomes indirectly through mediators. These findings highlighted the importance of addressing psychosocial issues and their interrelationships in cardiac rehabilitation.

The coronary artery bypass experience: gender differences

OBJECTIVE

The primary purpose of this study was to examine differences between women and men on physical, social and psychological domains of health quality of life before, 1 month after, and 3 months after coronary artery bypass surgery.

DESIGN

A prospective, longitudinal design was used.

SETTING

The study was conducted at a Midwestern, 500-bed community hospital with an ongoing cardiothoracic surgical program.

PARTICIPANTS

Forty pairs of women and men matched on age within 5 years and body surface area within 0.1m 2.

INSTRUMENTS

The physical, social and psychological domains of health quality of life were assessed using the following instruments: Ferrans and Powers Quality of Life Index, Specific Activity Scale, Symptom Scale, Profile of Mood States, Overall Health Rating Index, and Personal Resource Questionnaire.

RESULTS

Both women and men improved on physical and psychological measures following coronary artery bypass surgery. Compared with men, women reported more shortness of breath and depression and lower ratings of activity, vigor, and overall health. Measures of social support yielded little information.

CONCLUSIONS

Despite matching for age and body surface area, women did not have as favorable an outcome after surgery as men. Continued research needs to further examine the interaction of physical outcomes and depression in women after coronary artery bypass surgery.

Patient characteristics can predict improvement in functional health after elective coronary artery bypass grafting

BACKGROUND

Despite many patients undergoing coronary artery bypass grafting (CABG) to improve their functional status, literature in this area is limited. The purpose of this study is to determine the effect of CABG on the functional health of an elective population and to identify preoperative patient characteristics associated with improved functional health after surgery.

METHODS

Physical and mental functional health was assessed before and 6 months after surgery with the Short-Form Health Survey (SF-36) in 1,061 consecutive patients undergoing elective, isolated CABG. Survey data were complete in 529 patients (49.9%). Preoperative information on patient demographics, severity of cardiovascular illness, and disease comorbidities was also prospectively collected.

RESULTS

Six months post-CABG the mean summary score for physical function improved by 31.9% over baseline (45.1 versus 34.2, p < 0.0001). The mean summary score for mental function improved by 7.3% over baseline (51.3 versus 47.8, p < 0.0001). Overall 73.2% of patients showed improvement in physical function and 41.6% showed improvement in mental function. Multivariate logistic regression identified certain preoperative characteristics as negative correlates of a significant improvement in physical functioning: body mass index 35 kg/m2 or greater, diabetes with sequelae, chronic obstructive pulmonary disease, peripheral vascular disease, and baseline physical function. Baseline mental function and chronic obstructive pulmonary disease were identified as negative correlates and older age as a positive correlate of significant improvement in mental functioning.

CONCLUSIONS

Patient characteristics exist that impact functional health after elective CABG. Knowledge of these characteristics may be helpful when counseling patients about expected improvement in functional health with CABG.

Depression and anxiety in coronary artery bypass grafting patients

PURPOSE

Heart surgery is a factor triggering off specific emotional and physiological responses of a patient. In spite of positive somatic effects of surgery, depression and anxiety can persist or appear for the first time after the operation worsening the patient's psychosocial functioning and quality of life. The aim of this study is to offer a prospective view on the incidence and course of self-reported depression and anxiety in coronary artery bypass graft (CABG) patients.

SUBJECT AND METHODS

After informed consent, 53 patients who submitted to CABG were examined a few days before and after the operation and 3 months after CABG. They completed the Spielberger Anxiety Questionnaire and Beck Depression Inventory.

RESULTS

Approximately 55% of the patients had high a level of anxiety preoperatively. Shortly after the surgery, 34% of patients and after 3 months 32% of them had clinically relevant level of anxiety. Thirty-two percent of patients before the surgery, 28% immediately after CABG and 26% at follow-up were depressed.

CONCLUSIONS

High preoperative depression, state and trait anxiety scores appear to be predictors of postoperative psychological outcome. Preoperative assessment can identify patients at risk for clinical levels of postoperative anxiety and depression. Psychological preventive counseling and psychiatric intervention can reduce patients' emotional distress, medical and economic costs.

Safety of antidepressant drugs in the patient with cardiac disease: a review of the literature

Patients with cardiac disease, specifically ischemic heart disease and heart failure, have a higher frequency of major depressive disorder than patients without cardiac disease. The pathophysiologic reason for this is not completely understood. Previous depression, other debilitating illnesses, and type A personality are risk factors for the development of depression in cardiac patients. Depression has been shown to lower the threshold for ventricular arrhythmias. Therefore, treatment of depression potentially may prolong life in these patients. Antidepressant options that have been evaluated include several of the tricyclic antidepressants, trazodone, bupropion, and several of the selective serotonin reuptake inhibitors. Individual antidepressant drugs vary in their pharmacologic activity and side-effect profiles. Although clinical data are limited, it is important to individualize therapy in order to minimize cardiac adverse effects. Clinicians are encouraged to evaluate patients with cardiac disease for major depressive disorder and to consider antidepressant drug therapy for these patients when appropriate.

Sex differences in heart disease incidence and prevalence: implications for intervention

Women present clinically with coronary disease later in life than men do, and given their increased life expectancy compared to men, represent an increasingly larger proportion of patients with coronary disease. Coronary disease in women results in a large human and financial burden to the healthcare system. Effective prevention measures should integrate the clinical and social features of coronary disease which are specific to women and should be anchored within a comprehensive understanding of the burden of coronary disease in women. While attention has been recently directed at coronary disease in women, there is relatively limited information on the incidence and prevalence of coronary disease in women and how it may have changed over time; few studies include sufficient numbers of women to draw appropriate inference. This paper reviews the epidemiology of coronary disease in women and discusses the implications for intervention.

Effects of a telephone counseling intervention on psychosocial adjustment in women following a cardiac event

OBJECTIVE

The purpose of this study was to test the effect of a post-discharge telephone counseling intervention on women's psychosocial adjustment following a cardiac event.

DESIGN

The study was a prospective, randomized, controlled trial.

PATIENTS

Women (n = 196) were recruited from 4 hospitals in Sydney, Australia, who were hospitalized for coronary artery disease: myocardial infarction, coronary artery bypass grafts, coronary angioplasty, or stable angina. Women were randomized to usual care (n = 103) or telephone counseling (n = 93) and were 67 years of age (range 34-92). The majority had not completed high school (92%) and were not employed (84%).

OUTCOMES

Psychosocial adjustment was measured by the Psychosocial Adjustment to Illness Scale and the Hospital Anxiety and Depression Scale the day before hospital discharge and 12 weeks postdischarge.

INTERVENTION

Individualized information and support, was designed to promote self-managed recovery and psychosocial adjustment, and began with an evaluation during admission and was followed up by telephone counseling at 1, 2, 3, and 6 weeks after discharge.

RESULTS

The intervention had no effect on psychosocial adjustment (F[1,182] = 0.06, P =.8), anxiety (F[1,182] = 0.15, P =.69) or depression (F[1,182] = 0.11, P =.74) at 12 weeks after discharge. Women made significant improvements during the 12 weeks on mean scores for psychosocial adjustment (F[1,182] = 58.37, P =.00), anxiety (F [1,182] = 74.58, P =.00) and depression (F[1,182] = 14.11, P =.00). The predictors of poor psychosocial outcomes for women included being less than 55 years of age, being unemployed or retired, having poor psychosocial adjustment to illness at baseline, having readmission, or experiencing a stressful, personal event during follow-up.

CONCLUSIONS

Women at risk for poor outcomes following hospitalization for a cardiac event can be identified (ie, women less than 55 years of age, unemployed or retired, poorly adjusted to their cardiac illness, or readmitted to hospital within 12 weeks of a previous cardiac admission), but an effective intervention to enhance psychosocial outcomes remains to be established.

Social support and experimental pain

OBJECTIVE

The purpose of this experimental study was to supplement and expand on clinical research demonstrating that the provision of social support is associated with lower levels of acute pain.

METHODS

Undergraduates (52 men and 49 women) performed the cold pressor task either alone or accompanied by a friend or stranger who provided active support, passive support, or interaction. Pain perception was measured on a 10-point scale.

RESULTS

Participants in the active support and passive support conditions reported less pain than participants in the alone and interaction conditions, regardless of whether they were paired with a friend or stranger.

CONCLUSIONS

These data suggest that the presence of an individual who provides passive or active support reduces experimental pain.

Body image and depressive symptoms as correlates of self-reported versus clinician-reported physiologic function

PURPOSE

This study examined the relationships between physiologic function, depressive symptoms, and body image among maintenance cardiac rehabilitation participants. Physiologic function was operationalized as both functional status and functional capacity.

METHODS

Participants were 72 men (mean age = 67.3 years) all of whom had experienced a traumatic cardiac event (ie, myocardial infarction, valve replacement surgery, coronary artery bypass graft surgery, percutaneous transluminal coronary angioplasty), and had completed some type of physician-supervised acute cardiac rehabilitation (ie, phase I and phase II). Measures of body image (social physique anxiety and body appearance satisfaction), self-reported functional status, clinician-reported functional capacity (ie, V0(2) and peak power), and depressive symptoms were collected.

RESULTS

Hierarchic multiple regression analyses revealed that both functional capacity and functional status explained significant variance in social physique anxiety (R(2) = 0.11, P<.05 and R(2) = 0.18, P<.05, respectively), whereas only functional status was a significant predictor of body appearance satisfaction (R(2) = 0.37, P<.01). Contrary to our hypotheses, depressive symptoms were not significantly related to either psychosocial or physiologic indices of functional well-being.

CONCLUSIONS

Both patient perceptions of functional status and clinical measures of functional capacity are important aspects of psychosocial well-being among cardiac patients.

Gender-specific changes in quality of life following cardiovascular disease: a prospective study

Gender-specific changes in Quality of Life (QoL) following cardiovascular disease (CVD) were studied in 208 patients to determine whether gender-related differences in postmorbid QoL result from differences in disease severity, premorbid QoL, or different CVD-related recovery. Premorbid data were available from a community-based survey. Follow-ups were done at 6 weeks, 6 months, and 12 months after diagnosis. Results showed that females had worse QoL at all three postmorbid assessments compared to males. However, multivariate analyses adjusting for premorbid gender differences and disease severity showed no significant gender-related differences for physical and psychologic functioning. Therefore, gender differences in QoL following CVD mainly result from premorbid differences in QoL, age, comorbidity, and disease severity at the time of diagnosis, and do not appear to be the consequence of gender-specific recovery. However, in clinical practice it is important to acknowledge the poorer QoL of females following CVD.

Factors influencing health-related quality of life in cardiac rehabilitation patients

Associations of age, gender, cardiac procedure (coronary artery bypass grafting or percutaneous transluminal coronary angioplasty), risk stratification, and number of comorbidities with health-related quality of life (HRQL) were examined among 217 men and 84 women (mean age, 63+/-11 years) consecutively enrolled in a phase II cardiac rehabilitation program. Female gender and high-risk stratification were independently associated with impaired treatment gains in most areas of HRQL. Older age and having a greater number of comorbidities were also associated with impaired gains in specific areas. HRQL was generally lower at baseline but not post-treatment in coronary artery bypass grafting vs. percutaneous transluminal coronary angioplasty patients. Cardiac rehabilitation patients also had lower HRQL scores than an age-matched, normative sample at baseline (most areas) and post-treatment (mainly on role physical). Findings reinforce the need for cardiac rehabilitation programs to tailor assessments and risk factor modification strategies to patient characteristics associated with low levels of HRQL, especially in women and those with higher risk stratification.

Barriers to participation in and adherence to cardiac rehabilitation programs: a critical literature review

Despite the documented evidence of the benefits of cardiac rehabilitation (CR) in enhancing recovery and reducing mortality following a myocardial infarction, only about one third of patients participate in such programs. Adherence to these programs is an even bigger problem, with only about one third maintaining attendance in these programs after 6 months. This review summarizes research that has investigated barriers to participation and adherence to CR programs. Some consistent factors found to be associated with participation in CR programs include lack of referral by physicians, associated illness, specific cardiac diagnoses, reimbursement, self-efficacy, perceived benefits of CR, distance and transportation, self-concept, self-motivation, family composition, social support, self-esteem, and occupation. Factors associated with non-adherence include being older, female gender, having fewer years of formal education, perceiving the benefits of CR, having angina, and being less physically active during leisure time. However, many of the studies have methodologic flaws, with very few controlled, randomized studies, making the findings tentative. Problems in objectively measuring adherence to unstructured, non-hospital-based programs, which are an increasingly popular alternative to traditional programs, are discussed. Suggestions for reducing barriers to participation and adherence to CR programs, as well as for future research aimed at clearly identifying these barriers, are discussed.

Impact of in-home defibrillators on postmyocardial infarction patients and their significant others: an interview study

OBJECTIVE

To investigate the impact of automated external defibrillator (AED) placement in the homes of postmyocardial infarction (MI) patients and their significant others.

DESIGN

This qualitative study used a semistructured interview to examine a nonrandomized convenience sample recruited from a larger study of home AEDs.

SETTING AND PARTICIPANTS

Patients (and their significant others) were recruited from an ongoing study of AED use in the home. Seventeen interviews with 15 patients (14 men, 1 woman) and 16 significant others (1 man, 15 women) aged 39 to 80 years were performed in patients' homes.

METHODS

Verbatim transcripts of audiotaped interviews were reviewed, and responses were categorized. Other data were obtained from hospital chart abstraction.

RESULTS

The majority of subjects noted only positive effects of the presence of home AEDs (eg, giving them feelings of security and control). There was no evidence that AED presence in the home caused excessive anxiety or stress either in patients or their significant others, nor were they perceived to cause relationship stress. On average, patients and their significant others estimated a 38% and 43% (respectively) risk of cardiac arrest and a 92% and 87% likelihood of a successful resuscitation with the use of the AED. Subjects' perceived risk of cardiac arrest were subjectively related to their estimate of current health status, size of infarction, and symptoms during their MI. Subjects also related their estimates of risk to their likelihood of traveling with their AED and whether they would consider purchasing one. Significant others had high confidence in their ability to properly use the AED.

CONCLUSIONS

AEDs were valued highly by subjects and enhanced their perceived control over their heart disease. This was especially true for subjects who believed that their risk of cardiac arrest was high. The possible effects of providing education regarding expert estimates of the likelihood of cardiac arrest and of a successful resuscitation at the time of AED placement are discussed.

Cardiac rehabilitation I: review of psychosocial factors

Cardiovascular disease (CVD) is the leading cause of death and disability for women and men. There are gender differences in recovery from coronary events, which may be due physiological, sociodemographic, or psychosocial factors. Cardiac rehabilitation programs have beneficial effects on coronary recovery. The following presents a review of the literature from MedLine (1997-2001) and PsychInfo (1984-2001) on gender differences in participation in cardiac rehabilitation programs, with a focus on depression, anxiety, self-efficacy and social support. A critical analysis of gaps in the literature as well as areas for future research are presented.

Cardiac rehabilitation II: referral and participation

Cardiovascular disease (CVD) is the leading cause of death and disability for women and men. Substantial health risks continue following ischemic coronary events (ICEs), but secondary prevention efforts, including cardiac rehabilitation (CR), have beneficial effects on both early and late mortality and morbidity. This prospective study examined the relationship among psychosocial factors and CR referral and participation patterns in 906 (586 men, 320 women) patients from the coronary intensive care unit (CICU) over the course of six months. Only 30% of participants were referred to CR programs, with significantly fewer women being referred. A logistic regression analysis was used to determine whether depression, anxiety, self-efficacy, or social support predicted CR participation six months following an ICE, while controlling for sociodemographic factors. Results show that higher family income, greater anxiety symptomatology, and higher self-efficacy were significantly predictive of CR participation at six months. Implications for women's recovery from an ICE are discussed.

Differential effects of premorbid physical and emotional health on recovery from acute events

OBJECTIVES

Emotional health may have an important effect on disease onset, but there has been little work evaluating premorbid emotional health on recovery from disability that results from acute medical events. The aim of this study is to determine whether premorbid emotional health is predictive of recovery in functional ability 1 year after reporting a stroke, heart attack, or hip fracture (event).

DESIGN

A prospective cohort study of an older population-based sample from 1986 to 1992.

SETTING

Data are from baseline and six annual follow-ups of the North Carolina Established Population for Epidemiological Study of the Elderly.

PARTICIPANTS

Two hundred forty whites and blacks aged 65 and older who reported a stroke, heart attack, or hip fracture during one of the first five follow-up interviews and had an increased level of disability at that follow-up.

MEASUREMENT

Improvement in disability in activities of daily living (ADLs) 1 year postevent.

RESULTS

High depressive symptoms at baseline showed a significant association with poorer recovery in functional ability 1-year postevent after adjustments were made for sociodemographic characteristics, smoking status, ADLs at time of event, cognitive status, and prior history of disease. Compared with nondepressed subjects, depressed subjects had an odds ratio (OR) of 0.38 (95% confidence interval (CI) = 0.16-0.94) for recovery 1 year after reporting a stroke, heart attack, or hip fracture. Additionally, among subjects who reported low depressive symptoms, high positive affect was significantly associated with increased odds of recovery (OR = 2.70, 95% CI = 1.10-6.68), adjusting for the same variables.

CONCLUSIONS

Emotional health, independent of other baseline measures, is associated with recovery in functional ability 1 year after a major health event. Our findings suggest that reducing premorbid levels of depressive symptoms or increasing positive affect may help the recovery process.

Psychosocial characteristics after acute myocardial infarction: the ENRICHD pilot study. Enhancing Recovery in Coronary Heart Disease

PURPOSE

Psychosocial factors, such as emotional distress and social isolation, have been increasingly recognized as important risk factors for patients' recovery from acute myocardial infarction (AMI). This study examined age, gender, and ethnic differences in depression and general distress, social support, and health-related quality of life after AMI.

METHODS

Data came from a series of 88 patients aged 62.1 +/- 14.2 years (46% female) who were hospitalized for AMI at eight different US clinical centers participating in the Enhancing Recovery in Coronary Heart Disease (ENRICHD) Pilot Study. Standardized psychometric measures were administered to assess three psychosocial domains: (1) depression and general distress (mental health functioning), (2) social support, and (3) health-related quality of life. Multivariate analysis of variance was used to examine the effects of age, gender, and ethnic differences in each of the three psychosocial domains.

RESULTS

Female patients reported higher levels of depression and distress compared with male patients (P = .040). Gender differences in mental health functioning differed by age (P = .046), with the greatest differences observed among younger female patients. Older patients (P = .014) and female patients (P = .025) reported lower levels of social support compared with younger and male patients, respectively. Minority patients did not differ from nonminority patients in mental health functioning or social support, and there were no significant differences in post-AMI quality of life on the basis of age, gender, or ethnicity.

CONCLUSIONS

The psychosocial risk profile after AMI may be different for male and female patients, and interventions may need to take account of each gender's specific needs.

Emotional and functional outcomes in women with coronary heart disease

Instruments used to measure emotional and functional outcomes of coronary heart disease show a fairly high level of consistency. Scores on depression scales are typically higher in women than men, yet this finding must be balanced with data showing that mean scores for depression are low. Both sexes report moderate levels of anxiety after a cardiac event; however, global mental health is rated as relatively high. Women report lower levels of physical activity and higher levels of disruption in functional activities than men. Women also report resuming household activities early in their recovery, a finding most likely reflective of traditional role responsibilities. Last, for both sexes, emotional distress and functional disability decrease over time and appear to be stable by 6 months after the event.
