Microarray Profiling of Differentially Expressed Genes in Coronary Artery Bypass Grafts of High-Risk Patients with Postoperative Cognitive Dysfunctions. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:1457. [PMID: 36674212 PMCID: PMC9859359 DOI: 10.3390/ijerph20021457] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/07/2022] [Revised: 01/07/2023] [Accepted: 01/10/2023] [Indexed: 06/17/2023]
Abstract
Postoperative cognitive dysfunction (POCD) is cognitive decline after surgery. The authors hypothesized that gene-level changes could be involved in the pathogenesis of POCD. The present study evaluated the incidence of POCD and its associated differentially expressed genes. This was a prospective cohort study conducted on high-risk coronary artery bypass graft patients aged 40 to 75 years. POCD classification was based on a one standard deviation decline in the postoperative scores compared to the preoperative scores. The differentially expressed genes were identified using microarray analysis and validated using quantitative RT-PCR. Forty-six patients were recruited and completed the study. The incidence of POCD was identified using a set of neurocognitive assessments and found to be at 17% in these high-risk CABG patients. Six samples were selected for the gene expression analyses (3 non-POCD and 3 POCD samples). The findings showed five differentially expressed genes in the POCD group compared to the non-POCD group. The upregulated gene was ERFE, whereas the downregulated genes were KIR2DS2, KIR2DS3, KIR3DL2, and LIM2. According to the results, the gene expression profiles of POCD can be used to find potential proteins for POCD diagnostic and predictive biomarkers. Understanding the molecular mechanism of POCD development will further lead to early detection and intervention to reduce the severity of POCD, and hence, reduce the mortality and morbidity rate due to the condition.

The Malay version of SF-36 health survey instrument: testing data quality, scaling assumptions, reliability and validity in post-coronary artery bypass grafting (CABG) surgery patients at the National Heart Institute (Institut Jantung Negara-IJN), Kuala Lumpur. Health Qual Life Outcomes 2021; 19:50. [PMID: 33563262 PMCID: PMC7874445 DOI: 10.1186/s12955-020-01658-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2020] [Accepted: 12/21/2020] [Indexed: 11/15/2022] Open
Abstract
BACKGROUND The Short Form 36 (SF-36) is a scoring system comprising of 36 items categorized into eight constructs corresponding to patients' health-related quality of life. It has been used extensively in various countries on different sub-populations and used to indicate the health status and help to ascertain the effect of clinical interventions on the particular population. OBJECTIVE To examine the psychometric properties of the Malay version of SF-36 (Malay SF-36) summated rating scales and validate the scale among post-coronary artery bypass grafting surgery (CABG) patients at the National Heart Institute (IJN), Kuala Lumpur. METHODS Five hundred and nine post-CABG patients at the IJN, Malaysia completed the questionnaires between 1 July and 31 December 2017. Psychometric tests endorsed by the "International Quality of Life Assessment Project" were utilised. RESULTS The data quality was excellent with a high questionnaire completion rate (100%). As hypothesized, the ordering of item means within scales was clustered. In unison, scaling assumptions were satisfied. Good discriminant validity was shown between subsets of patients with various levels of health status. Notwithstanding, there were probably translation issues of the Physical Functioning scale which showed small ceiling effects. We clearly observed high ceiling and floor effects in both Role Physical and Role Emotional scale most probably attributed to the dichotomous style of their choice of responses. Cronbach alpha values of the eight scales ranged from 0.73 to 0.90, showing good internal consistency reliability. Confirmatory Factor Analysis (CFA) confirmed the 8-factor solution and Composite Reliability revealed internal consistency reliability except for Vitality and Social Functioning. Based on the Average Variance Extracted (AVE), convergent validity was adequate except for two domains. Discriminant Validity is good for the eight constructs as the √AVE are generally higher than the correlation coefficients between the latent constructs. CONCLUSION The scoring for the Malay SF-36 based on the summated ratings method was proven to be valid to be applied in our local clinical population. The CFA, fitness estimates, reliability and validity assessments suggest that the Malay version of SF36 is a valid and reliable instrument. However, further work is warranted to further refine the convergent validity and reliability of some scales.

Abstract
<b>Introduction:</b> Ischemic heart disease is the most common cause of death in the world. The lives of patients with vascular defects can be saved by coronary artery bypass grafting (CABG). However, it is associated with an increased risk of developing depression after surgery. <br><b>Meterial and Methods:</b> The aim of the study is to present the results of the latest research on postoperative depression after CABG, including studies describing the course of the disease, its consequences for the patient's prognosis and treatment. The publications available on the PubMed platform published after 2011 were reviewed. <br><b>Results:</b> Depression before and after CABG affects 30-40% of patients, mostly women. Established after surgery and untreated, it persists for many years. The level of anxiety in patients decreases systematically after surgery. Indicators that may correlate with the patient's postoperative depression, including cortisol, high sensitivity C-reactive protein (hsCRP) and oxidative stress biomarkers, are being investigated. The occurrence of depression in patients after CABG has a number of negative consequences. Those include: weaker response to treatment, greater chance of relapse, and increased readmission frequency and mortality. Treatment of patients with this disorder involves the use of antidepressants (most often SSRIs - selective serotonin reuptake inhibitor) and/or various types of psychotherapy with cognitive behavioral therapy (CBT) at the forefront. <br><b>Conclusions:</b> Depression following CABG decreases the quality of life and worsens patient prognosis. It is necessary to detect this condition early after surgery and to apply treatment, taking into account the cardiological disorders of the patient.

Assessment of the Quality of Life in Patients before and after Coronary Artery Bypass Grafting (CABG): A Prospective Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17041417. [PMID: 32098322 PMCID: PMC7068373 DOI: 10.3390/ijerph17041417] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 12/29/2019] [Revised: 02/19/2020] [Accepted: 02/19/2020] [Indexed: 01/21/2023]
Abstract
The aim of this study was to examine the quality of life and to report on the utility and QALY measures in patients before and after coronary artery bypass grafting (CABG); to investigate whether the SF-12 is comparable with the SF-36 for measuring health-related quality of life of patients with CABG; and to determine the impact of individual predictors on poor quality of life assessment after rehabilitation. This prospective study was conducted between January 2017 and December 2018 at the University Hospital Center Osijek, at three time points: pre-operation, 1 month after surgery, and after rehabilitation. The study was conducted with the SF-36 and SF-12 health questionnaires on 47 participants. After rehabilitation, there was a significant improvement in all domains of quality of life. The highest score was given to the change in pain (BP); mean scores were 63.8 (95% CI 56.9 to 70.6) (p = 0.001). The lowest grade (the lowest quality) after rehabilitation was in the domain of limitations due to physical difficulties (RP); arithmetic mean was 48.5 (95% CI 41 to 55.9) (p < 0.001). Quality-adjusted life-year was 0.41 (95% CI 0.38–0.44) after the CABG. The results of this study show that patients with coronary heart disease have poor quality of life before surgery. One month after the surgery, the quality of life improved, but was still inadequate. One year after surgery, satisfactory results were obtained in almost all subscales. The SF-36, SF-12, and its components, can be used effectively in patients with CABG. Age, gender, lifestyle, and risk factors in our sample of participants are not predictors of poor quality of life assessment after rehabilitation.

Abstract
OBJECTIVE This study was done to investigate the effect of preoperative peer education on patients' adherence to medication and lifestyle changes after Coronary Artery Bypass Graft (CABG). METHODS In this randomized clinical trial, the peers of CABG patients conducted preoperative educational sessions at the ward in groups of 4-5 (n = 36) while the control group (n = 34) received routine education by a nurse. Adherence of both groups to medication and recommendations for lifestyle modification including physical activity, smoking, and diet was measured one and two months after discharge. RESULTS A multivariate analysis of co-variance showed the significant effect of peer education on adherence (F = 32.586, p < 0.001; η2 = 0.671). Univariate ANCOVA revealed a significant difference in adherence to diet between the two groups (F = 62.316, p = 0 0.0001; η2 = 0.482). Based on the repeated measures ANOVA, peer education significantly improved the CABG patients' adherence to diet (F = 55.373, p = 0.0001) and their total adherence (F = 9.911, p = 0.002) compared to the control group. CONCLUSION Preoperative peer education had a significant effect on improving CABG patients' adherence to lifestyle changes after hospital discharge. PRACTICE IMPLICATION Peer education can be used as an effective method to improve the CABG patients ' adherence to lifestyle changes.

Abstract
OBJECTIVES To explore predictors of return to work in patients after acute coronary syndrome and coronary artery bypass grafting, taking into account cognitive performance, depression, physical capacity, and self-assessment of the occupational prognosis. DESIGN Observational, prospective, bicentric. SETTING Postacute 3-week inpatient cardiac rehabilitation (CR). PARTICIPANTS Patients (N=401) <65 years of age (mean 54.5±6.3y), 80% men. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Status of return to work (RTW) 6 months after discharge from CR. RESULTS The regression model for RTW showed negative associations for depression (odds ratio 0.52 per SD, 95% confidence interval 0.36-0.76, P=.001), age (odds ratio 0.72, 95% confidence interval 0.52-1.00, P=.047), and in particular for a negative subjective occupational prognosis (expected incapacity for work odds ratio 0.19, 95% confidence interval 0.06-0.59, P=.004; unemployment odds ratio 0.08, 95% confidence interval 0.01-0.72, P=.024; retirement odds ratio 0.07, 95% confidence interval 0.01-0.067, P=.021). Positive predictors were employment before the cardiac event (odds ratio 9.66, 95% confidence interval 3.10-30.12, P<.001), capacity to work (fit vs unfit) at discharge from CR (odds ratio 3.15, 95% confidence interval 1.35-7.35, P=.008), and maximum exercise capacity (odds ratio 1.49, 95% confidence interval 1.06-2.11, P=.022). Cognitive performance had no effect. CONCLUSIONS The patient's perception and expectation regarding the occupational prognosis play a crucial role in predicting return to work 6 months after an acute cardiac event and CR. These findings highlight the importance of the multimodal approach, in particular psychosocial components, of CR.

Abstract
Thirty-six patients with angina were investigated by treadmill exercise testing and coronary angiography prior to coronary artery surgery. Severity of angina was judged by interview and self-assessment visual analogue scale and all patients were psychiatrically assessed. Further physical and psychiatric assessments were made at 3 and 6 months postoperatively. Eleven patients (31%) had significant psychiatric morbidity preoperatively and these had worse symptom scores and exercise tolerance compared with non-psychiatric cases, despite equivalent coronary angiographic findings and left ventricular function. Postoperatively, exercise tolerance improved equally in both groups but psychiatric cases remained significantly more symptomatic. Psychiatric morbidity remained unchanged throughout the study. We conclude that almost one third of patients with severe angina have psychiatric morbidity which is associated with a poor symptomatic response to coronary artery surgery, despite objective improvement in exercise tolerance. Ways of improving the symptomatic response to surgery in patients with coexisting psychiatric morbidity should be studied.

Abstract
OBJECTIVES To investigate the overall and the sex-specific association of preoperative and one-year post coronary artery bypass (CABG) surgery symptoms of depression and anxiety with 11-year all-cause mortality. METHODS A multicenter prospective study including 1125 patients who completed the Hospital Anxiety and Depression Scale (HADS) before an elective CABG surgery, of whom 850 completed the HADS again at one-year follow-up. Information on all-cause mortality was obtained through the Israeli Ministry of Internal Affairs Register. Multivariable adjusted Cox regression models quantified the association of symptoms of depression and anxiety with all-cause mortality. RESULTS Females comprised 22.7% of the cohort and were 5.5years older than males (70.0±9.3 and 64.4±10.3years, respectively). Controlling for sociodemographic and lifestyle factors, illness severity and post-surgery participation in cardiac rehabilitation, there was little evidence of an association between preoperative symptoms of depression and mortality in males [adjusted hazard ratio (aHRmales)=1.03, 95% CI 0.99-1.07, p=0.21] or females (aHRfemales=1.01, 95% CI 0.95-1.08, p=0.7). One-year postoperative symptoms of depression were associated with mortality in both males (aHRmales=1.05, 95% CI 1.01-1.10, p=0.03) and females (aHRfemales=1.07, 95% CI 1.02-1.13, p=0.013). Preoperative symptoms of anxiety were unrelated to mortality overall, but among females postoperative symptoms of anxiety predicted 11-year mortality (aHRfemales=1.07, 95% CI 1.00-1.14, p=0.049). There was no HADS by sex interaction (p for interaction=0.12-0.99). CONCLUSIONS Symptoms of depression one-year after surgery were positively related to mortality with little evidence for sex differences. These findings underscore the need for identification and treatment of psychiatric symptoms in patients undergoing CABG surgery. CLINICAL TRIAL REGISTRATION ClinicalTrials.gov: NCT00356863.

Abstract
PURPOSE to assess clinical efficacy of early post discharge rehabilitation of patients with ischemic heart disease (IHD) after coronary artery bypass grafting (CABG) in conditions of a polyclinical department of cardiological rehabilitation (stage III of cardiorehabilitation). MATERIAL AND METHODS We included in this study 36 men with IHD in 3-8 weeks (mean 7.8+/-1.6 weeks) after CABG. Patients were randomized in 2groups: patients of the main group attended special "School for patients recovering after CABG" [School] (60-80 min sessions once a week for 5 weeks) and participated in a program of monitored (up to 60 min 3 times a week for 4 months) and unmonitored (home based) exercise training. Patients of the control group attended School and were given advice to do physical exercises at home. Follow up duration was 1 year. RESULTS Main group. Compared with baseline values after 4 months exercise duration increased 32.6% (p<0.05), this effect persisted at 12 month; threshold exercise load increased 35.2% (p<0.05) after 4, 53.9% after 6, and 49.5% after 12 month. After 4 and 12 months of training some increases of left ventricular (LV) ejection fraction and stroke volume, and decrease of LV end systolic volume occurred. Physical training in this group was associated with improvement of parameters of quality of life. During 12 months of follow up there were no significant changes of concentrations of total and low density lipoprotein cholesterol (TC, LDLC). In the control group slight increase of exercise duration was observed only at 12 months (9.8%, p<0.05), and it was not accompanied by dynamics of exercise tolerance. Increases of concentrations of TC (10.2%, p<0.05) and LDLC (15.6%, p<0.05) were registered at 12 months. Serious cardiovascular complications in the main group (physical training + educational School) were three times less frequent than in the control group (attendance of School only) (11.1 vs. 39.2%, respectively.

Abstract
OBJECTIVE To examine the relative incidence of newly recorded diagnosis of depression after spinal surgery as a proxy for the risk of post-spinal surgery depression. PATIENTS AND METHODS We used the longitudinal California Office of Statewide Health Planning and Development database (January 1, 2000, through December 31, 2010) to identify patients who underwent spinal surgery during these years. Patients with documented depression before surgery were excluded. Risk of new postoperative depression was determined via the incidence of newly recorded depression on any hospitalization subsequent to surgery. For comparison, this risk was also determined for patients hospitalized during the same time period for coronary artery bypass grafting, hysterectomy, cholecystectomy, chronic obstructive pulmonary disease, congestive heart failure exacerbation, or uncomplicated vaginal delivery. RESULTS Our review identified 1,078,639 patients. Relative to the uncomplicated vaginal delivery cohort, the adjusted hazard ratios (HRs) for newly recorded depression within 5 years after the admission of interest were 5.05 for spinal surgery (95% CI, 4.79-5.33), 2.33 for coronary artery bypass grafting (95% CI, 2.15-2.54), 3.04 for hysterectomy (95% CI, 2.88-3.21), 2.51 for cholecystectomy (95% CI, 2.35-2.69), 2.44 for congestive heart failure exacerbation (95% CI, 2.28-2.61), and 3.04 for chronic obstructive pulmonary disease (95% CI, 2.83-3.26). Among patients who underwent spinal surgery, this risk of postoperative depression was highest for patients who underwent fusion surgery (HR, 1.28; 95% CI, 1.22-1.36) or had undergone multiple spinal operations (HR, 1.22; 95% CI, 1.16-1.29) during the analyzed period. CONCLUSION Patients who undergo spinal surgery have a higher risk for postoperative depression than patients treated for other surgical or medical conditions known to be associated with depression.

Abstract
The purposes of this investigation were to identify a zone of normality for ratings of perceived exertion (RPE) and to compare the RPE responses in patients with coronary artery disease to this zone. The zone was generated from RPE estimated during the last minute of each stage of a Bruce treadmill test in 44 normal adult men. RPE were regressed against the corresponding MET level for each exercise stage. The zone was established as the 95% confidence interval (CI) spanning the average RPE vs MET regression line. RPE estimated during the last 1.0 min. of a Bruce or Modified Balke treadmill test administered to adult men ( n = 37) with coronary artery disease were compared to the 95% CI zone. A total of 19 (51%) of the coronary artery disease patients estimated RPE during a progressively incremented treadmill test that were above the zone, indicating a comparatively greater than normal perception of strain for a given metabolic stress. The presently generated zone provides a practical use of RPE in the interpretation of clinical exercise tests.

Abstract
This study examined the strategy utilized by patients with cardiovascular disease to regulate exercise intensity using the Rating of Perceived Exertion (RPE) and tested if a step-up procedure would reduce overshoot of target heart rate (HR). Also the study investigated if Prescription Congruence and Intensity Discrimination, components of the Intensity Self-regulation Model, could be validated for these patients. An estimation and production paradigm was used. HR was measured at 2-min. intervals during 6-min. stationary cycle ergometer exercise trials. Data for four experimental trials were compared: (1) a work intensity set by experimenter to achieve a target RPE of 11 (Estimation 11), (2) an intensity set by experimenter to achieve a target RPE of 13 (Estimation 13), (3) an intensity varied by participant every 2 min. to produce a target RPE of 13 (Production 13), and (4) a Step-up Procedure with the intensity varied by participant, first producing a target RPE of 11 during the first 2 min., followed by producing a target RPE of 13 from min. 2 to 6 of exercise (Production 11 + 13). A very small effect size was found for HR between Production 13 and Estimation 13, and a moderate effect size was noted for the increased HR when patients produced a target RPE of 13 as compared to 11. The participants could be divided into 2 groups: 10 patients comprised a Higher group whose HR at 2 min. during Production 13 was greater than HR at 2 min. during Estimation 13, and 6 patients in a Lower group with HR at 2 min. during Production 13 less than or equal to HR during Estimation 13. A large effect size was found at 6 min. for the reductions of the Higher group's HR overshoot and for the Lower group's HR undershoot during Production 13. All participants in the Higher group ( n = 10) had a clinically significant 1ER overshoot of 5 beats · min.−1 at 2 min. during Production 13. Using a Step-up Procedure (Production 11 + 13), a large effect size was found for the reduced number of patients ( n = 3) with an overshoot of 5 beats · min.−1 at 2 min. This supports the ability of participants in cardiac rehabilitation programs to meet the Prescription Congruence and Intensity Discrimination components of the Intensity Self-regulation Model in the RPE 11–13 zone. Evidence was found for overshoot/undershoot of target HR at 2 min., supporting a proposed third component, Production Strategy, of the Intensity Self-regulation Model. The 2-min. Step-up Procedure reduced some patients' tendency to “overshoot” target intensity.

Abstract
Background Increasing access to revascularisation procedures is a key aspect of a National Service Framework. Coronary artery bypass grafting (CABG) is effective in relieving symptoms and reducing mortality but some patients do not report an improved quality of life or experience a good recovery. Aims To describe the recovery trajectory after CABG and identify facilitators and barriers to recovery. Methods Semi-structured interviews were conducted with 11 patients who had previously undergone elective, isolated, first-time CABG and with 10 health professionals experienced in caring for these patients. Results Thematic analysis identified the following themes: definition and timeline of recovery, preparation for surgery including information provision, attitude to surgery and confidence in staff, clinical factors and the in-patient experience. The key finding is the different recovery trajectory between patients with severe versus mild pre-operative symptoms; patients with few pre-CABG symptoms reported a much longer recovery time. Conclusions This study has provided insights into the barriers and facilitators to recovery after CABG and the processes involved. Findings have indicated areas where health professionals can intervene to aid patients’ long-term recovery and thereby maximise the benefits of CABG.

[PMID: 16627003 DOI: 10.1016/j.ejcnurse.2006.01.007] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/25/2005] [Revised: 01/01/2006] [Accepted: 01/26/2006] [Indexed: 11/16/2022]
Abstract
BACKGROUND The aim of the coronary artery bypass graft operation is to relieve anginal symptoms and improve functional ability, quality of life and survival. However, having the surgery does not always have the desired outcomes. Although numerous studies have investigated the outcomes of coronary artery bypass graft operation, little attention has been given to patients' perceptions of the outcomes or effects of the operation on health and well-being over time. AIM To explore patients' perspectives on the effects of coronary artery bypass surgery on health and well-being over time. METHODS As part of a larger mixed methods study, 62 in-depth audio-taped interviews with men and women who had undergone coronary artery bypass approximately 7 years earlier were conducted. Interviews were audio-taped and transcribed. Data were analysed thematically. This paper reports the findings from the qualitative component of the larger study. FINDINGS The four main themes: 'Recovery and Rehabilitation', 'Seven Years On', 'Maintaining a Positive Approach', and 'Health Behaviour Change' reflect the main areas of focus emerging across the interviews and provide credible overarching descriptors of the sub-themes they encompass. The 11 sub-themes identified were recognised as central to the patients' experiences of their health and well-being over the longer-term. CONCLUSIONS Although most patients report improved health and well-being after coronary artery bypass operation, many have described their recovery and rehabilitation as a complex process with both short and long term effects. The insights provided by participants help improve our understanding of the impact of the operation on patients' health and well-being over time. We believe these insights will help us to anticipate the possible needs of future patients and enable us develop appropriate interventions that may facilitate self-management for optimal recovery and health maintenance.

Abstract
The purpose of this study was to describe the experiences of persons whose spouses have newly diagnosed coronary artery disease (CAD). The purpose was to obtain knowledge that would help us to understand better the life of persons with a chronically ill spouse and to develop the education and rehabilitation of both the patients and their spouses. Data were collected from healthy spouses by an open-ended question. There were 146 informants. They were asked to write about their experiences of everyday life after their spouse had been diagnosed for CAD. The data were analyzed by methods of content analysis. The following categories were formulated to describe the healthy spouses' experiences: slow pace of life, limited life and unsure life. Slow pace of life meant that the disease had been adopted as a normal part of life. Life was organized in a new way, and the earlier busy and work-oriented lifestyle had been given up. The informants whose spouses had medication considered their personal freedom to be limited, because they had to assume responsibility for the care of their spouses. The spouses of the patients who had undergone bypass surgery (CABS) or angioplasty (PTCA) had a new role in the family. They had to monitor for symptoms, treat symptoms, take care, understand and support. They had to assume responsibility for everyday life. They felt themselves to be alone in that situation. They did not receive support from health care providers. All informants felt uncertainty due to financial problems, poorly planned care and unexpected changes in the course of the disease. As a conclusion, it can be said that life was limited by the sick spouse's needs. The disease caused changes in emotional balance, a need for continuous control of life, fears about a new myocardial infarction and worries about many issues of everyday life.

Abstract
BACKGROUND The waiting period for coronary artery bypass surgery is a difficult time for patients and families. Pre-operative cardiac rehabilitation may be safe and effective, but there is limited evidence regarding patients' experience and perceptions of such intervention. AIM To describe patients' experiences of a pre-operative programme of cardiac rehabilitation developed specifically for those awaiting coronary artery bypass surgery. METHOD A convenience sample of eight patients awaiting non-urgent surgery who had completed a 12 week pilot programme of cardiac rehabilitation were invited to be interviewed using a descriptive phenomenological approach. Domicillary interviews using an open technique were taped, transcribed and analysed using Colaizzi's framework. RESULTS Participants described this programme as a useful means of improving exercise capacity and decreasing anxiety. Through the combination of exercise, advice and support participants stated that their initial fear that exercise would cause a heart attack was replaced with confidence, enabling them to become fitter and modify other risk factors. CONCLUSIONS Findings of this study suggest that the programme was acceptable and perceived as beneficial by participants. Further research is required to evaluate the efficacy of pre-operative rehabilitation on risk factor modification.

Abstract
The purpose of this study was to describe coronary artery bypass grafting (CABG) and percutaneous transluminal coronary angioplasty (PTCA) patients' need for nursing informational support in health-related (HRQoL) items before and after coronary artery procedures. As well we present the adequacy of informational support from patients' viewpoint. The study sample (N=625) consisted of consecutive male (N=439) and female (N=176) patients with CAD who were treated with elective CABG or PTCA. The data were collected by structured interview before coronary artery procedures and by mailed questionnaires 6 and 12 months afterwards in 1999-2001. Patients in both groups reported needing the most information about recovery and psychosocial functioning before and after the treatments. Single HRQoL items identified that the expectations of women and men differed during the follow-up period. Women in the PTCA group needed more informational support than men before procedures, while men needed more support afterwards. Our results suggest that the content of informational support is different for male and female patients before and after the coronary artery procedures. The effects of nursing interventions and instruments for measuring change in patients' outcome resulting from nursing interventions should be developed further.

Abstract
OBJECTIVE Depression and anxiety are associated with poor recovery in coronary artery bypass graft (CABG) patients, but little is known about predictors of depression and anxiety symptoms. DESIGN We tested the prospective association between attachment orientation, and symptoms of depression and anxiety in CABG patients, 6-8 weeks, and 12 months following surgery. METHOD One hundred and fifty-five patients who were undergoing planned CABG surgery were recruited. Patients completed questionnaires measuring attachment, depression, and anxiety prior to surgery, then 6-8 weeks, and 12 months after surgery. RESULTS Attachment anxiety predicted symptoms of depression and anxiety at both follow-up time points, whereas attachment avoidance was not associated with depression or anxiety symptoms. The findings remained significant when controlling for baseline mood scores, social support, demographic, and clinical risk factors. CONCLUSION These results suggest that attachment anxiety is associated with short-term and long-term depression and anxiety symptoms following CABG surgery. These results may offer important insight into understanding the recovery process in CABG surgery. Statement of contribution What is already known on this subject? Depression and anxiety symptoms are twice more likely to occur in coronary artery bypass graft (CABG) populations than in any other medical group. Depression and anxiety are associated with poor recovery following cardiac surgery. Predictors of depression and anxiety in CABG patients have been underexplored. What does this study add? This study highlights the importance of close interpersonal relationships on health. Attachment anxiety was prospectively associated with higher levels of depression and anxiety. These results add to understanding mechanisms linked to recovery following CABG.

Abstract
Few studies have examined differences in patient perceptions of care between health care systems. This study compared the perceptions of male patients undergoing coronary artery bypass graft surgery in 43 Veterans Health Administration (VA) hospitals (N = 808) and 102 US private sector hospitals (N = 2271) from 1995 to 1998. Patient perceptions were measured by a validated survey that was mailed to patients after discharge. For 8 of the 9 dimensions assessed by the survey, VA patients were more likely (P < .001) than private sector patients to note a problem with care (eg, Coordination, 48% versus 40%; Patient Education and Communication, 50% versus 40%; Respect for Patient Preferences, 49% versus 41%). In comparisons limited to major teaching hospitals, VA patients were more likely to note a problem for 5 dimensions. The findings indicate that patient perceptions of care may be lower in VA than in private sector hospitals. Future studies should examine whether the VA's recent focus on improving patient satisfaction has narrowed these differences.

Abstract
We aimed to explore the combined contribution of pre-surgical depression and anxiety symptoms for recovery following coronary artery bypass graft (CABG) using data from 251 participants. Participants were assessed prior to surgery for depression and anxiety symptoms and followed up at 12 months to assess pain and physical symptoms, while hospital emergency admissions and death/major adverse cardiac events (MACE) were monitored on average 2.68 years after CABG. After controlling for covariates, baseline anxiety symptoms, but not depression, were associated with greater pain (β = 0.231, p = 0.014) and greater physical symptoms (β = 0.194, p = 0.034) 12 months after surgery. On the other hand, after controlling for covariates, baseline depression symptoms, but not anxiety, were associated with greater odds of having an emergency admission (OR 1.088, CI 1.010–1.171, p = 0.027) and greater hazard of death/MACE (HR 1.137, CI 1.042–1.240, p = 0.004). These findings point to different pathways linking mood symptoms with recovery after CABG surgery.

Abstract
Human beings with unmet needs related to their health and illnesses are the central focus of the domain of nursing. It is proposed in this column that nurses who conduct their practice from a nursing theory base, while assisting individuals and families to meet their health needs, are more likely to provide comprehensive, individualized care that exemplifies best practices. The Neuman systems model has been widely acclaimed to guide practice, yet specific examples are few in the published literature. The purpose of this column is to present two case studies based upon Neuman systems model; one case is directed toward family care, and the other demonstrates care with an individual. Theory-based exemplars serve as teaching tools for students and practicing nurses. These case studies illustrate how nurses' actions, directed by Neuman's wholistic principles, integrate evidence-based practice and generate high quality care.

Abstract
Little is known about the symptom experience throughout the trajectory of recovery for patients after coronary artery bypass surgery (CABS). This study investigates the preoperative and postoperative symptoms experienced by younger (< 65 years) and older (= 65 years) patients (N= 102) who had undergone CABS. Reported preoperative symptoms were angina, shortness of breath, dizziness, and sweating. At 1 week post-CABS, symptoms were incisional pain, wound drainage, chest congestion, shortness of breath, dizziness, sweating, swollen feet, and loss of appetite; incisional pain and swollen feet were reported by a few patients at 6 weeks after CABS. The incidence and frequency of postoperative symptoms declined over time. There were several age-related differences in symptom reports prior to and at 1 and 6 weeks after the procedure. Such information can be used to plan the care of patients undergoing CABS, to prepare them for normal recovery, and to determine the need for symptom management by health care providers.

Abstract
This article introduces the concept of clinical life to capture a form of life produced in the pursuit and wake of medically achieved longevity. Relying on the retrospective accounts of 28 individuals over age 70 who have undergone cardiac bypass surgery, angioplasty or a stent procedure, as well as interviews with their families and with clinicians, we examine three features of clinical life. First, patients do not distinguish between clinical possibility and clinical promise, and thus assume that life can and will be improved by medical intervention in late life. Rather than anticipating a range of potential treatment outcomes, patients therefore expect the best-case scenario: that medical procedures will reverse aging, disease and the march of time. Second, patients then assess the value of their post-procedure lives in accordance with that expectation. Norms regarding what life ‘should be like’ at particular ages are continually recalibrated to the horizon of what is clinically possible. And third, the price of living longer entails a double-edged relationship with the clinic – it generates opportunities for bodily restoration and increased self-worth but also creates ambivalence about the value of life. This latter feature of clinical life is rarely publicly acknowledged in an environment that emphasizes medical promise.

Abstract
This study examined associations between social sharing of emotions, social support and preoperative psychological distress. Social sharing was operationalized in terms of quantity and quality. Quantity of social sharing was measured daily using a diary method. Quality of social sharing was measured with the Quality of Sharing Inventory. Participants were 157 hospitalized Greek patients. Hierarchical regression analysis showed that controlling for distress on admission, quality of social sharing was negatively related to distress one day before surgery ( p < .01). No effects were found for quantity of social sharing. Results emphasize the importance of studying qualitative aspects of emotional disclosure.

Abstract
Recovery symptoms and related mood states during early recovery after coronary artery bypass graft surgery (CABG) have never been assessed in Thailand. This cross-sectional descriptive correlational study was to identify the relationships between frequency of recovery symptoms and mood states of a convenience sample of 91 Thai CABG patients during 2 weeks after discharge. Standardized tools/procedures were used to measure the variables of interest. The most common recovery symptoms were chest and leg incision pain, having trouble sleeping, and neck and shoulder or back discomfort. The most common mood states were confusion, anxiety, and anger, respectively. In addition, Thai CABG patients who had more frequent recovery symptoms also had greater negative mood disturbance. These findings provide a beginning explanation about the phenomena of recovery symptoms and mood states in a specific culture, Thai CABG patients.
