A structural equation model linking health literacy, self efficacy and quality of life in adults with coronary heart disease. BMC Cardiovasc Disord 2022; 22:285. [PMID: 35739464 PMCID: PMC9229518 DOI: 10.1186/s12872-022-02720-8] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2022] [Accepted: 06/13/2022] [Indexed: 12/12/2022] Open
Abstract
Background Cardiovascular disease is the world major cause of death. There is sufficient evidence that patients with coronary heart disease (CHD) experience poor quality of life. Health literacy and self efficacy are modifiable psychosocial factors that could affect quality of life, and these factors should be considered as targets for intervention. As the relationships among health literacy, self efficacy, and quality of life in the CHD population have not been well understood. Thus, we constructed the structure equation model in these valuables. Methods A cross-sectional study of a convenience sample among 200 patients with CHD were participated from outpatient clinics in three tertiary general hospitals in Baoding City in mainland China, from December 2018 to June 2019. Data regarding demographic features, health literacy, self efficacy and quality of life were assessed. A structure equation model was used to construct and validate the pathways. Results The mean age of the study sampled patients was 65.37 years old. The average level of health literacy, self efficacy and quality of life were 9.6 ± 3.5, 28.8 ± 13.9 and 381.8 ± 130.1 respectively. Significant associations were observed from health literacy to quality of life, and self efficacy played a partial mediating role between health literacy and quality of life in the CHD population. Health literacy and self efficacy explained for 59.6% of the variance in quality of life. Conclusions Health literacy had a direct influence on quality of life, and an indirect influence on quality of life via self efficacy in the patients with CHD.

Abstract
PURPOSE The Seattle Angina Questionnaire (SAQ) is a widely used patient-reported measure of health status in patients with coronary artery disease. Comparisons of SAQ scores amongst population groups and over time rely on the assumption that its factorial structure is invariant. This study evaluates the measurement invariance of the SAQ across different demographic and clinical groups and over time. METHODS Data were obtained from the Alberta Provincial Project on Outcome Assessment in Coronary Heart Disease registry, a registry of patients who received coronary angiogram in Alberta, Canada. The study cohort consists of adult patients who completed the paper-based version of the 16-item Canadian version of the SAQ (SAQ-CAN) 2 weeks and 1-year post-coronary angiogram between 2009 and 2016. Multi-group confirmatory factor analysis was used to assess configural, weak, strong, and strict measurement invariance across age groups, sex, angina type, treatment, and over time. Model fit was assessed using the comparative fit index and root mean square error of approximation. RESULTS Of the 8101 patients included in these analysis, 1300 (16.1%) were at least 75 years old, while 1755 (21.7%) were female, 5154 (63.6%) were diagnosed with acute coronary syndrome, 1177 (14.5%) received coronary artery bypass graft treatment, and 3279 had complete data on the SAQ-CAN at both occasions. There was evidence of strict invariance across age, sex, and angina type, and treatment groups, but partial strict invariance was established over time. CONCLUSION SAQ-CAN can be used to compare the health status of coronary artery disease patients across population groups and over time.

Quality of Life Changes in Acute Coronary Syndromes Patients: A Systematic Review and Meta-Analysis. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17186889. [PMID: 32967168 PMCID: PMC7558854 DOI: 10.3390/ijerph17186889] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/23/2020] [Revised: 09/08/2020] [Accepted: 09/19/2020] [Indexed: 12/26/2022]
Abstract
There is little up-to-date evidence about changes in quality of life following treatment for acute coronary syndrome (ACS) patients. The main aim of this review was to assess the changes in QoL in ACS patients after treatment. We undertook a systematic review and meta-analysis of quantitative studies. The search included studies that described the change of QoL of ACS patients after receiving treatment options such as percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG) and medical therapy (MT). We synthesized findings using content analysis and pooled the estimates using meta-analysis. We used the PRISMA guidelines to select and appraise the studies and report the findings. Twenty-nine (29) articles were included in the review. We found a significant improvement of QoL in ACS patients after receiving treatment. Particularly, the meta-analytic association found that the mean QoL of patients diagnosed with ACS was higher after receiving treatment compared to baseline (overall pooled mean difference = 31.88; 95% CI = 31.64–52.11, I2 = 98) with patients on PCI having slightly lower QoL gains (pooled mean difference = 30.22; 95% CI = 29.9–30.53, I2 = 0%) compared to those on CABG (pooled mean difference = 34.01; 95% CI = 33.66–34.37, I2 = 0%). The review confirmed that QoL of ACS patients improved after receiving treatment therapies although varied by the treatment options and patients’ preferences. This suggests the need to perform further study on the QoL, patient preferences and physicians’ decision to prescription of treatment options.

Abstract
BACKGROUND Given limited knowledge on the extent of social inequalities in longer-term work ability of people with a chronic disease, this study analyzes social inequalities of three consecutive indicators of work ability following medical rehabilitation in a large sample of insured employees. METHODS Based on data from the German statutory pension insurance, a representative 20% random sample of all employed persons undergoing medical rehabilitation between 2006 and 2008 was included in a longitudinal analysis (n=219 584 persons). Three measures of consecutive work-related outcomes (physicians' assessment of work ability at discharge; return to work in the year thereafter; disability pension during follow-up) and socioeconomic position (SEP) (education, occupational position and income) were assessed. Adjusted relative risks (RRs) for each outcome were calculated according to SEP, applying Poisson regression analysis. RESULTS The measures of SEP were associated with all three outcomes of work ability in the fully adjusted models. Relatively strongest relationships were observed for education as SEP measure, and they were particularly pronounced for 'low work ability' (RR=2.38 for lower secondary education compared to tertiary education; 95% CI: 2.26-2.51). Based on average marginal effects, absolute differences of work ability by SEP indicate a socially graded pattern, with only few exceptions. CONCLUSIONS Despite Germany's universal access to medical and vocational rehabilitation social inequalities in longer-term work ability following chronic disease persist, thus calling for targeted programmes of prevention and occupational health promotion.

Abstract
The primary objective of the present study was to assess independent and interactive relations of perceived social support and self-efficacy with four quality of life (QOL) domains namely physical, psychological, social, and environmental in cardiovascular disease (CVD) patients from a South Asian region. Participants were 172 (age 22-60 years) patients recruited from three major government sector hospitals from the fifth biggest city of South Asia. It was found that overall CVD patients had a better QOL in psychological and environmental domains compared to social and psychological. Furthermore, findings from hierarchical regression analyses indicated that perceived social support and self-efficacy were positively associated with the four QOL domains. Besides main effects, a synergistic interaction between social support and self-efficacy emerged indicating that perceived social support was strongly associated with physical and social QOL in CVD patients who had higher self-efficacy levels, while, perceived social support was weakly associated with the physical and social QOL in CVD patients who had lower self-efficacy levels.

Abstract
AIMS This study aimed to investigate whether hospitalisation is associated with increased risk of disability retirement differently across four occupational classes. METHODS 170,510 employees of the City of Helsinki, Finland were followed from 1990 to 2013 using national registers for hospitalisations and disability retirement. Increases in the risk of disability retirement after hospitalisation for any cause, cardiovascular diseases, musculoskeletal disorders, mental disorders, malignant neoplasms, respiratory diseases and injuries were assessed across four occupational classes: professional, semi-professional, routine non-manual and manual, using competing risks models. RESULTS In general, hospitalisation showed a slightly more increased risk of disability retirement in the lower ranking occupational classes. Hospitalisation among women for mental disorders showed a more increased risk in the professional class (hazard ratio 14.73, 95% confidence interval 12.67 to 17.12) compared to the routine manual class (hazard ratio 7.27, 95% confidence interval 6.60 to 8.02). Occupational class differences were similar for men and women. The risk of disability retirement among women increased most in the routine non-manual class after hospitalisation for musculoskeletal disorders and injuries, and most in the professional class after hospitalisation for cardiovascular diseases. The corresponding risks among men increased most in the two lowest ranking classes after hospitalisation for injuries. CONCLUSIONS Ill-health as measured by hospitalisation affected disability retirement in four occupational classes differently, and the effects also varied by the diagnostic group of hospitalisation. Interventions that tackle work disability should consider the impact of ill-health on functioning while taking into account working conditions in each occupational class.

Abstract
Objective To evaluate the level of health-related quality of life (HRQoL), life satisfaction, and their present awareness of cardiac rehabilitation (CR) program in people with cardiovascular diseases. Methods A questionnaire survey was completed by 53 patients (mean age, 65.7±11.6 years; 33 men and 20 women) with unstable angina, myocardial infarction, or heart failure. The questionnaire included the Medical Outcome Study 36-item Short-Form Health Survey (MOS SF-36), life domain satisfaction measure (LDSM), and the awareness and degree of using CR program. Results The average scores of physical component summary (PCS) and mental component summary (MCS) were 47.7±18.5 and 56.5±19.5, respectively. There were significant differences in physical role (F=4.2, p=0.02), vitality (F=10.7, p<0.001), mental health (F=15.9, p<0.001), PCS (F=3.6, p=0.034), and MCS (F=11.9, p<0.001) between disease types. The average LDSM score was 4.7±1.5. Age and disease duration were negatively correlated with multiple HRQoL areas (p<0.05). Monthly income, ejection fraction, and LDSM were positively correlated with several MOS SF-36 factors (p<0.05). However, the number of modifiable risk factors had no significant correlation with medication. Thirty-seven subjects (69.8%) answered that they had not previously heard about CR program. Seventeen patients (32.1%) reported that they were actively participating in CR program. Most people said that a reasonable cost of CR was less than 100,000 Korean won per month. Conclusion CR should focus on improving the physical components of quality of life. In addition, physicians should actively promote CR to cardiovascular disease patients to expand the reach of CR program.

Abstract
BACKGROUND The aim is to know the factors related to the evolution of Health Related Quality of Life (HRQL) in Coronary Patients (CP) from a longitudinal perspective using an appropriate method that handles missing data adequately when the mechanism of missingness is uncertain. METHODS Prospective study with repeated measures at baseline, 3 and 6months. 250 patients with acute myocardial infarction or unstable angina were studied. Sociodemographic and clinical data were collected at baseline. Mental health (GHQ-28) and HRQL (SF-36v1) were assessed during the follow-up. The missingness mechanism was tested. Friedman test and partial eta-squared were used to analyse changes in SF-36 scores and WGEE were used to identify the predictors of the evolution of HRQL. RESULTS 95 dropped out after 3months and 72 after 6months. The missingness was likely to be at random. All the dimensions of the SF-36 improved over time, except PF. The factors related to the evolution of HRQL were: being woman (B=-23.9 in RE; B=-6.9 in MCS), older age (B=-0.5 in BP; B=-0.3 in VT), being single/separated (B=-14.5 in GH; B=-14.1 in SF; B=-23.3 in MH) and widow(er) (B=-23.2 PF; B=-29.8 in SF), hypertensive (B=-19.8 in RP; B=-8.9 in VT), worse mental health (B=-3 in PF; B=-2.8 in RP; B=-3.1 in BP; B=-1.2 in PCS; B=-3.8 in VT; B=-2.6 in SF), previous history of CHD (B=-12.5 in PF; B=-5.2 in PCS), and performing heart-healthy physical activities (B=13.9 in PF). CONCLUSIONS HRQL improves over time. A global approach, including age, marital status, performing physical activities or hypertension, is required to improve HRQL in CP.

Abstract
The purpose of this study was to validate the applicability of our proposed disease-specific questionnaire to Cantonese coronary heart disease (CHD) patients. During the investigation from August 2010 to March 2012, 1000 Cantonese inpatients were recruited. The reliability of the scale was judged by the internal consistency, and the content and construct validity were assessed by using Pearson correlation and confirmatory factor analysis, respectively. Results showed that the Cronbach’s α coefficient for the whole scale and most domains/facets were larger than .70 (.59 to .93). Most items had moderate to strong Pearson correlations with their respective facets ( r > 0.50). Confirmatory factor analysis showed that the indices for goodness of fit were nearly acceptable. Overall, the QLICD-CHD scale has adequate psychometric properties when applied to Cantonese CHD patients.

Abstract
Background Few studies have compared change in the health-related quality of life (HRQL) following treatment of non-ST-elevation acute coronary syndrome (NSTE-ACS) with either percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG). This study is to compare changes in HRQL six months after hospital discharge between NSTE-ACS patients who underwent either PCI or CABG. Methods HRQL was assessed using the Seattle angina questionnaire at admission and six months after discharge in 1012 consecutive patients with NSTE-ACS. To assess associations of PCI and CABG with HRQL changes, logistic regression models were constructed treating changes in the score of each dimension of the Seattle angina questionnaire as dependent variables. Results Although both the PCI and CABG groups experienced angina relief and other improvements at 6-month follow-up (P < 0.001), the CABG relative to PCI group showed more significant improvements in angina frequency (P = 0.044) and quality of life (P = 0.028). In multivariable logistic analysis, CABG also was an independent predictor for both improvement of angina frequency (OR: 1.62, 95%CI: 1.09−4.63, P = 0.042) and quality of life (OR: 2.04, 95%CI: 1.26−6.92, P = 0.038) relative to PCI. Conclusions In patients with NSTE-ACS, both PCI and CABG provide great improvement in disease-specific health status at six months, with that of CABG being more prominent in terms of angina frequency and quality of life.

Abstract
Background Quality of life (QOL) for patients with coronary heart disease (CHD) is now concerned worldwide with the specific instruments being seldom and no one developed by the modular approach. Objectives This paper is aimed to develop the CHD scale of the system of Quality of Life Instruments for Chronic Diseases (QLICD-CHD) by the modular approach and validate it by both classical test theory and Generalizability Theory. Methods The QLICD-CHD was developed based on programmed decision procedures with multiple nominal and focus group discussions, in-depth interview, pre-testing and quantitative statistical procedures. 146 inpatients with CHD were used to provide the data measuring QOL three times before and after treatments. The psychometric properties of the scale were evaluated with respect to validity, reliability and responsiveness employing correlation analysis, factor analyses, multi-trait scaling analysis, t-tests and also G studies and D studies of Genralizability Theory analysis. Results Multi-trait scaling analysis, correlation and factor analyses confirmed good construct validity and criterion-related validity when using SF-36 as a criterion. The internal consistency α and test-retest reliability coefficients (Pearson r and Intra-class correlations ICC) for the overall instrument and all domains were higher than 0.70 and 0.80 respectively; The overall and all domains except for social domain had statistically significant changes after treatments with moderate effect size SRM (standardized response mea) ranging from 0.32 to 0.67. G-coefficients and index of dependability (Ф coefficients) confirmed the reliability of the scale further with more exact variance components. Conclusions The QLICD-CHD has good validity, reliability, and moderate responsiveness and some highlights, and can be used as the quality of life instrument for patients with CHD. However, in order to obtain better reliability, the numbers of items for social domain should be increased or the items’ quality, not quantity, should be improved.

Abstract
AIMS Long-term health-related quality of life (HRQOL) in the elderly after percutaneous coronary intervention (PCI) is unknown. We 1) compared HRQOL of elderly (≥70 years) with younger patients (<70 years) at 6, 12, 36 months post-PCI, and 2) examined whether predictors of impaired HRQOL 36 months post-PCI differed between older and younger patients. METHODS AND RESULTS A prospective cohort of 651 PCI patients (26.3% ≥70 years) completed the SF-36 at 6, 12 and 36 months post-PCI. Older patients experienced a poorer physical HRQOL at all time points and worse mental HRQOL with respect to vitality and role emotional functioning (all p-values<0.05). By 36 months, the HRQOL for the older patients worsened in five of the eight subdomains (all p-values<0.05). Younger patients did not experience enduring changes in HRQOL, with the exception of role physical functioning. Predictors of impaired HRQOL were generally different for the elderly (diabetes, previous PCI) compared to younger cohorts (smoking, previous bypass surgery, ACE inhibitors), although poor six-month HRQOL, anxiety and depression were common predictors for both groups. CONCLUSIONS Elderly PCI patients experience a deteriorating and poorer HRQOL than younger patients across three years. Contrary to younger patients, three-year HRQOL of elderly patients is irrespective of adverse events during outcomes.

Abstract
Background Health-related quality of life (HRQoL) is an important outcome for patients diagnosed with coronary heart disease. This report describes predictors of physical and mental HRQoL at six months post-hospitalisation for myocardial infarction. Methods Participants were myocardial infarction patients (n=430) admitted to two tertiary referral centres in Brisbane, Australia who completed a six month coronary heart disease secondary prevention trial (ProActive Heart). Outcome variables were HRQoL (Short Form-36) at six months, including a physical and mental summary score. Baseline predictors included demographics and clinical variables, health behaviours, and psychosocial variables. Stepwise forward multiple linear regression analyses were used to identify significant independent predictors of six month HRQoL. Results Physical HRQoL was lower in participants who: were older (p<0.001); were unemployed (p=0.03); had lower baseline physical and mental HRQoL scores (p<0.001); had lower confidence levels in meeting sufficient physical activity recommendations (p<0.001); had no intention to be physically active in the next six months (p<0.001); and were more sedentary (p=0.001). Mental HRQoL was lower in participants who: were younger (p=0.01); had lower baseline mental HRQoL (p<0.001); were more sedentary (p=0.01) were depressed (p<0.001); and had lower social support (p=0.001). Conclusions This study has clinical implications as identification of indicators of lower physical and mental HRQoL outcomes for myocardial infarction patients allows for targeted counselling or coronary heart disease secondary prevention efforts.

Abstract
INTRODUCTION Cardiovascular diseases are always one of the major causes of mortality in the world affecting all aspects of patients' lives. Therefore, this study was conducted to summarize and provide a clear view of quality of life in these patients in Iran through a systematic review on the results of previously conducted studies. METHODS In a systematic review, required information was collected by searching keywords of Iran, quality of life, heart failure, cardiac, heart, and their Persian equivalents in databases of Science Direct, Pubmed, IRAN doc, SID, Medlib and Magiran. The selected time period for searching articles was since 2000 to 2012. Inclusion criteria were: releasing of article during 2000 to 2012, articles reporting patients' quality of life in any domains of heart diseases, and articles published in Persian and English. Extracted results first were summarized in Extraction Table, and then analyzed manually. RESULTS Finally 18 of 1592 found articles were included in the study. A total of 3,797 cardiac patients' quality of life was measured using six different tools, the most important one of which was SF36 questionnaire. Among eight dimensions of SF36 questionnaire, the highest mean was for social role functioning with average score of 58.37 and the lowest for physical limitation (physical role functioning) with score of 42.95. Overall, mean of eight dimensions was 53.19. Among 4 general domains of quality of life, physical activity had the lowest average of 43.63 and average of general dimensions of quality of life was 47.65. The most important factors affecting quality of life were sex, age, education, marital status, occupational status, suffering duration, number of hospitalizations etc. CONCLUSION The results of the studies showed relatively low quality of life of cardiovascular patients in general. Therefore, according to the introduced effective factors in this study, it is necessary to consider regular programs for improving quality of life in these patients and providing suitable and qualitative services.

Abstract
BACKGROUND Healthcare providers are called on to assess and improve the health-related quality of life (HRQL) of patients with myocardial infarction (MI). However, there is lack of empirical data on HRQL of such individuals in mainland China. The purpose of this study is to assess HRQL and identify associated factors in hospitalized Chinese MI patients. METHODS A single group, cross-sectional design was adopted with a sample of 192 hospitalized MI patients at two teaching hospitals in Xi'an, People's Republic of China. HRQL was assessed using the Chinese Mandarin versions of the Short Form 36 health survey (SF-36), the Myocardial Infarction Dimensional Assessment Scale (MIDAS), and the Hospital Anxiety and Depression Scale (HADS). RESULTS Chinese MI patients reported poor HRQL as measured by both the generic (SF-36) and disease-specific (MIDAS) instruments. Advancing age and the presence of heart failure, anxiety, and depression were significant predictors of overall HRQL. Smoking and hypertension were significant predictors of the physical aspects of HRQL. CONCLUSIONS Assessing HRQL of hospitalized Chinese MI patients and identifying associated factors may help health professionals in the design and delivery of appropriately tailored and culturally relevant interventions to this group of patients.

Abstract
BACKGROUND AND OBJECTIVES Relatively little is known about the effects of hemodialysis frequency on the disability of patients with ESRD. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS This study examined changes in physical performance and self-reported physical health and functioning among subjects randomized to frequent (six times per week) compared with conventional (three times per week) hemodialysis in both the Frequent Hemodialysis Network daily (n=245) and nocturnal (n=87) trials. The main outcome measures were adjusted change in scores over 12 months on the short physical performance battery (SPPB), RAND 36-item health survey physical health composite (PHC), and physical functioning subscale (PF) based on the intention to treat principle. RESULTS Overall scores for SPPB, PHC, and PF were poor relative to population norms and in line with other studies in ESRD. In the Daily Trial, subjects randomized to frequent compared with conventional in-center hemodialysis experienced no significant change in SPPB (adjusted mean change of -0.20±0.19 versus -0.41±0.21, P=0.45) but experienced significant improvement in PHC (3.4±0.8 versus 0.4±0.8, P=0.009) and a relatively large change in PF that did not reach statistical significance. In the Nocturnal Trial, there were no significant differences among subjects randomized to frequent compared with conventional hemodialysis in SPPB (adjusted mean change of -0.92±0.44 versus -0.41±0.43, P=0.41), PHC (2.7±1.4 versus 2.1±1.5, P=0.75), or PF (-3.1±3.5 versus 1.1±3.6, P=0.40). CONCLUSIONS Frequent in-center hemodialysis compared with conventional in-center hemodialysis improved self-reported physical health and functioning but had no significant effect on objective physical performance. There were no significant effects of frequent nocturnal hemodialysis on the same physical metrics.

Abstract
INTRODUCTION Health-related quality of life (HRQOL) refers to a person's or group's perceived physical and mental health over time. Coronary heart disease (CHD) affects HRQOL and likely varies among groups. This study examined disparities in HRQOL among adults with self-reported CHD. METHODS We examined disparities in HRQOL by using the unhealthy days measurements among adults who self-reported CHD in the 2007 Behavioral Risk Factor Surveillance System state-based telephone survey. CHD was based on self-reported medical history of heart attack, angina, or coronary heart disease. We assessed differences in fair/poor health status, 14 or more physically unhealthy days, 14 or more mentally unhealthy days, 14 or more total unhealthy days (total of physically and mentally unhealthy days), and 14 or more activity-limited days. Multivariate logistic regression models included age, race/ethnicity, sex, education, annual household income, household size, and health insurance coverage. RESULTS Of the population surveyed, 35,378 (6.1%) self-reported CHD. Compared with non-Hispanic whites, Native Americans were more likely to report fair/poor health status (adjusted odds ratio [AOR], 1.7), 14 or more total unhealthy days (AOR, 1.6), 14 or more physically unhealthy days (AOR, 1.7), and 14 or more activity-limited days (AOR, 1.9). Hispanics were more likely than non-Hispanic whites to report fair/poor health status (AOR, 1.5) and less likely to report 14 or more activity-limited days (AOR, 0.5), and Asians were less likely to report 14 or more activity-limited days (AOR, 0.2). Non-Hispanic blacks did not differ in unhealthy days measurements from non-Hispanic whites. The proportion reporting 14 or more total unhealthy days increased with increasing age, was higher among women than men, and was lower with increasing levels of education and income. CONCLUSION There are sex, racial/ethnic, and socioeconomic disparities in HRQOL among people with CHD. Tailoring interventions to people who have both with CHD and poor HRQOL may assist in the overall management of CHD.

Farin E, Meder M. Personality and the physician-patient relationship as predictors of quality of life of cardiac patients after rehabilitation. Health Qual Life Outcomes 2010; 8:100. [PMID: 20840774 PMCID: PMC2949817 DOI: 10.1186/1477-7525-8-100] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2009] [Accepted: 09/14/2010] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND Numerous studies document the influence of psychosocial variables on the course of coronary heart disease. This study examines the influence of personality traits (trait anger, cynicism) and aspects of the physician-patient relationship (promoting patient participation by the physician, active communication behavior of the patient, trust in the physician) on the health related quality of life (HRQOL) of cardiac patients after rehabilitation. METHODS N = 331 patients with chronic ischemic heart disease were surveyed using questionnaires at two time points (beginning and end of 3-weeks inpatient rehabilitation). In addition, characteristics of the disease and cardiac risk factors were provided by the physician. HRQOL was measured using a total of six scales and three instruments: SF-12, MacNew questionnaire, and SAQ. Hierarchical regression analyses were carried out to predict HRQOL after rehabilitation, in which the baseline values of HRQOL, sociodemographic variables, characteristics of the disease and risk factors, personality traits, and finally the aspects of the physician-patient relationship were included stepwise. As a number of variables were used for the regression models, multiple imputation was conducted. RESULTS The baseline values explain most of the variance (42%-60%). After controlling the baseline values, the sociodemographic variables explain up to 5% incremental variance of HRQOL, with income being the most important predictor. The characteristics of the disease and cardiac risk factors explain between 0.4% and 3.8% incremental variance, however, variance increase is often not significant. The personality traits added in the fourth step explain up to 2% additional variance; trait anger is a significant predictor of HRQOL in three of the six scales. The features of the physician-patient relationship included in the last step lead to a significant increase in explained variance (between 1.3% and 3.9%) for all six scales. In particular, the physician's promotion of patient participation has a significant influence. The overall explanation of variance for HRQOL is between 50% and 64%. CONCLUSIONS Low income, a high level of trait anger, and low patient participation are significant risk factors, even if a number of potential confounders are adjusted. Research is needed that shows which causal pathway low income functions on and what therapies in rehabilitation can mitigate the disadvantage of persons with a high level of trait anger. The providers should implement measures to actively integrate rehabilitation patients in treatment (e.g. encourage them to ask questions).

Abstract
AIMS The study aimed to determine the quality of life and the relationship between cardiac risk factors and the quality of life in subjects diagnosed with coronary artery disease. BACKGROUND Coronary artery disease is the leading cause of adult deaths. The main goal of the therapy is to stop the progression of atherosclerotic coronary disease, ensure its regression and protect individuals from possible complications, increase quality of life and survival period by providing optimal physical, psychological and social conditions. DESIGN AND METHOD The sample population was 270 outpatients who were diagnosed Coronary artery disease at the Cardiology Policlinics of State Hospital during 21 May-20 July 2007. Socio-demographic information and risk factors were inquired during the period of data collection with two forms as the 'Demographic Characteristics Questionnaire' and 'Mac New Quality of Life Scale'. RESULTS According to the results of the study, it was found that 22.2% of the patients were under the age of risk group, 27.8% had diabetes, 47.5% had hypertension, 36.7% were smokers, and 40.7% had hyperlipidemia. It was established that 31.1% had four risk factors, no patients were risk-free, and the mean number of risk factors was 3.7 (SD 1.28). For the scores of the quality of life scale domains of the patients, the physical field, emotional field, social field and total quality were estimated to be 60.85, 69.34, 68.31 and 130.42, respectively. CONCLUSIONS It was found that there was a negatively statistically significant relation between the quality of life and hypertension and early familial Coronary artery disease history and that quality of life declined as the risk factors increased. RELEVANCE TO CLINICAL PRACTICE Risk-factor modification and organisation of training programmes with ensured participation of patients and their relatives are of critical importance in improving their quality of life.

Abstract
OBJECTIVES The impact of socioeconomic status (SES) on health previously studied demonstrates that low SES relates to lower health. In Greece, related studies are limited and focused on native population. The aim of this study was to assess the influence of residence, ethnicity and SES on health-related quality of life (HRQoL). METHODS The study was carried out in Thessaly using a sample of 1,372 individuals (18+ years old, response rate 91.4%) via face-to-face interview. Multiple stepwise linear regression analyses were performed investigating the impact of the above factors on HRQoL, measured by SF-36. Interaction effects between socioeconomic and demographic variables were performed. RESULTS Disadvantage of SES, i.e. primary education and low income, was associated with impaired HRQoL in physical and mental health. Albanians reported better HRQoL compared to Greeks but after controlling for SES factors health disparities became insignificant. Rural residents were related to better general and mental health. CONCLUSIONS SES is an independent predictor of HRQoL, but ethnicity and place of residence had weak impact. Investigating the underline mechanisms that impair HRQoL, so as to take policies that will elucidate the risk of poor health in disadvantage groups, is important.

Abstract
OBJECTIVE The objective of this study was to ascertain the reliability and predictive power of the World Health Organization's Quality of Life Questionnaire (WHOQOL-BREF) and Short Form 36 Health Survey questionnaire (SF-36) in coronary artery disease patients. METHODS Between May and September 2006, patients with coronary artery disease hospitalized in Tehran Heart Center were divided randomly into two groups of 268 patients (for assessment of QOL with the SF-36 questionnaire) and 275 patients (for assessment of QOL with the WHOQOL-BREF questionnaire). Cronbach's alpha coefficient was used to test reliability of the two questionnaires and a value of 0.7 or higher was considered satisfactory. RESULTS For the SF-36 and the WHOQOL-BREF questionnaires, Cronbach's alpha was 0.825 and 0.701, respectively, both of which exceeded 0.7. In SF-36 questionnaire, with the deletion of four items in the scales of mental health (1), role limitation - physical (16), and bodily pain (19), Cronbach's alpha was significantly increased. Also, in the BREF questionnaire, deletion of each of items 3, 4, 8, 9, 22, and/or 26 led to an increase in Cronbach's alpha. CONCLUSION Although the WHOQOL-BREF questionnaire is a reliable tool for the evaluation of QOL in coronary artery disease patients, its reliability was significantly lower than that of the SF-36 questionnaire and thus it can be less applicable than SF-36 for this purpose.

Abstract
OBJECTIVE Depression occurs commonly in coronary artery disease (CAD) and is associated with substantial disability. Modifiable cognitive determinants of depression in this population have not been identified. We investigated the impact of potentially modifiable illness beliefs about CAD on depressive symptomatology. We also examined the association between these beliefs and health-related quality of life (HRQOL) and socio-demographic variations in illness beliefs. METHODS A prospective study of 193 recently hospitalized CAD patients was conducted. Data were collected from medical records and by self-report 3 and 9 months post-discharge. Socio-demographic differences were analysed with independent sample t-tests. Predictive models were tested in a series of hierarchical linear regression equations that controlled for known clinical, psychosocial, and demographic correlates of outcome. RESULTS Negative illness beliefs, particularly those associated with the consequences of CAD, were significantly predictive of higher levels of depressive symptomatology at 3 and 9 months. Positive illness perceptions were significantly associated with better HRQOL outcomes. Older and less socially advantaged patients demonstrated more negative illness beliefs. CONCLUSIONS Illness beliefs are significantly associated with depressive symptomatology and HRQOL in CAD patients. These beliefs can be easily identified and constitute a meaningful and clinically accessible avenue for improving psychological morbidity and HRQOL in CAD patients. Older and more socially vulnerable patients may require heightened monitoring of their illness beliefs. Research needs to translate these and other predictive findings into interventions.

Abstract
Angina pectoris (AP) often responds to treatment, but in some, it becomes chronic or recurs over time. Identifying patients with continued AP is a necessary to understand its associations and implications. A baseline cohort with coronary disease and AP were surveyed 6 months and 1 year after catheterization for self-reported symptoms and quality of life. Patients were divided into 3 groups: chronic AP, recurrent AP, and AP free. Baseline characteristics, medications, revascularization, and quality of life are described. Regression analysis determined independent associations with chronic AP. Of the 1,109 patients with complete 1-year follow-up, 19% (n = 207) had chronic AP, 11% (n = 126) had recurrent AP, but most (70%, n = 776) were AP free. Patients with chronic and recurrent AP had similar cardiac histories, had more single vessel coronary disease, and underwent revascularization less often. Patients with recurrent AP had lower educational status and more often smoked. Patients with chronic AP were younger, were women, had higher body mass index, had more depression and lung disease, and had more frequent baseline AP. They also took more antianginals and other medications and had reduced physical function and health-related quality of life in relation to the persistence and frequency of symptoms (p <0.001). In conclusion, patients with chronic and recurrent AP represent unique populations in whom AP continues to negatively impact quality of life despite contemporary care.

Abstract
The preoperative status of coronary artery bypass graft (CABG) surgical patients is often evaluated as a means to assess operative risk for mortality and morbidity and to inform how preoperative status influences or predicts outcomes following CABG surgery. The purpose of this study was to examine the influence of coronary artery disease (CAD) risk factor burden on CABG patients' preoperative functioning (functional status and functional capacity). A convenience sample of 152 subjects, 65 years and older, who had been consecutively enrolled in a larger randomized clinical trial, was evaluated. The RISKO Heart Hazard Appraisal was used to quantify CAD risk factor burden of the subjects. There were significant differences by CAD risk factor burden group, with subjects in the highest CAD risk factor burden group having poorer general health functioning (F2,147=3.45; P<.05) and functional capacity (F2,147=5.43; P<.01). These findings elucidate the potential usefulness of evaluating CABG patients' preoperative CAD risk factor burden status.

Abstract
BACKGROUND Health-related quality of life (HRQOL) is an increasingly relevant outcome as the population ages and associated morbidities increase. The purpose of this study was to evaluate predictors of HRQOL among ethnically diverse women hospitalized for coronary heart disease (CHD) and determine the impact of a brief, educational intervention on HRQOL 6 months post-hospitalization. METHODS Women (n = 160; mean age 63 years, 53% minority) admitted for CHD at three academic hospitals who completed a 6 month secondary prevention trial were studied. The SF-36 was administered at admission and 6 months. Multiple linear regressions were used to identify significant independent predictors of 6 month HRQOL. RESULTS Significant improvements in HRQOL were noted from admission to 6 months post-hospitalization. Subjects reporting better HRQOL at 6 months included those who were employed, married, physically active, enrolled in cardiac rehabilitation, and not depressed. Women who received an educational intervention had significantly less bodily pain at 6 months compared with usual care in a model adjusted for baseline HRQOL and physical activity goal adherence (p = 0.04). CONCLUSIONS Baseline HRQOL (8 SF-36 subscales), physical activity (3 SF-36 subscales) and marital status (1 SF-36 subscale) were the major determinants of HRQOL at 6 months post-hospitalization. Future interventions and preventive efforts should be targeted to women with CHD who have impaired HRQOL and may be at increased risk of poor clinical outcomes.

Health Qual Life Outcomes 2006; 4:60.

Abstract
BACKGROUND We evaluated how well physicians' global estimates of disease severity correspond to more specific physician-rated disease variables as well as patients' self-rated health and other patient variables. METHODS We analyzed baseline data from 1662 primary care patients with chronic cardiac or pulmonary disease who were enrolled in a longitudinal study of health-related quality of life (HRQoL). Each patient's primary physician rated overall disease severity, estimated the two-year risk of hospitalization and mortality, and reported the use of disease-specific medications, tests, and subspecialty referrals. Patient variables included sociodemographic characteristics, psychosocial factors, self-rated health, and both generic and disease-specific HRQoL. RESULTS Physicians rated 40% of their patients "about average", 30% "worse", and 30% "better" than the typical patient seen with the specific target disorder. The physician's global estimate of disease severity was strongly associated (P < 0.001) with each of the five more specific elements of physician-rated disease severity, but only marginally associated with patient self-rated health. Multivariable regression identified a set of patient variables that explained 16.4% of the variance in physician-rated disease severity. CONCLUSION Physicians' global ratings may provide disease severity and prognostic information unique from and complementary to patient self-rated health and HRQoL measures. The elements influencing physician-rated disease severity and its predictive validity for clinical outcomes warrant prospective investigation.

[PMID: 16441887 PMCID: PMC1413520 DOI: 10.1186/1471-2458-6-18] [Citation(s) in RCA: 34] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2005] [Accepted: 01/27/2006] [Indexed: 12/05/2022] Open
Abstract
Background The aim of the study was to identify the changes in Health Related Quality of Life (HRQL) 3 months after discharge from hospital, in patients who have had an acute coronary episode, and to determine the clinical and sociodemographic variables that explain those changes. Methods HRQL was assessed in 132 patients while they were admitted to the hospital and at 3 months after discharge, using the SF-36 health questionnaire. To identify the variables associated with the change, multiple linear regression models were constructed for two summary dimensions of the SF-36 (PCS and MCS) taking the change in the score of the dimension as dependent variable. Results There were no significant differences between the patients who completed the monitoring (n = 76) and those who were dropped out. After three months, a significant decrease was observed in the dimensions of physical functioning, general health, vitality, and Physical Summary Component (PCS). The variables revascularisation, age, and the interaction between previous history of coronary heart disease (CHD) and the presence of one or more risk factors explained 16.6% of the decrease in the PCS. The decrease in the PCS was 6.4 points less in the patients who had undergone revascularisation, 0.2 points less for each year of age, and 4.7 points less in the patients who had antecedents of the illness as well as one or more risk factors. Conclusion The dimensions most affected at three months after an acute coronary episode were those related to the physical component. Undergoing revascularisation improved the PCS in patients, but in the younger patients and those without personal antecedents or risk factors, the PCS was affected more, perhaps due to greater expectations for recovery in these patients.
