Telemedical Intervention and Its Effect on Quality of Life in Chronic Heart Failure Patients: The Results from the Telemedicine and e-Health Solution Pilot Program.

(1) Background: Heart failure (HF) is not only a common cardiovascular disease with a poor prognosis. Its prevalence in developed countries equals 1-2% of the general population of adults, while in Poland HF, patients constitute 3.2% of the total population. Modern heart failure treatment should be focused not only on reducing the risk of death and the number of readmissions due to HF exacerbation but quality of life as well. Telemedicine has been suggested as a viable tool for enhancing HRQL. Therefore, we present the results of telemedical intervention in a group of HF patients and its effect on quality of life in chronic heart failure patients from a pilot study dedicated to reducing social inequalities in health through the use of telemedicine and e-health solutions. (2) Method: The project was a multicenter, open, non-controlled trial conducted by the University of Rzeszów, Poland. The data points were collected in the June 2023-December 2023 period from fourteen primary care units from five voivodeships, mostly considered social exclusion areas. A total of 52.7% of the patients recruited were Podkarpackie Voivodeship inhabitants. The result and discussion are presented based on the Chronic Heart Failure Questionnaire (CHFQ) and the EuroQol Visual Analogue Scale (EQVAS). (3) Results: During the program, a total of over 100,000 telemedicine examinations were conducted in the form of body weight measurement, heart rate, blood pressure tests, and 7-day Holter or 14-day event Holter assessment. Over the course of this study, coordinating the pilot program medical staff has ordered 570 changes in the patient's pharmacotherapy, confirming the positive impact on quality of life in the study group. (4) Conclusions: A comprehensive telemedical intervention can contribute to an improvement in the quality of life of patients with HF beyond what was achieved with the basic standard of care in the group of HF patients from the social exclusion region. It is now unclear if the result of the basic telemedical intervention would be constant after discontinuation of the mentioned pilot program.

Reliability and Validity of the Turkish Version of the Performance Measure for Activities of Daily Living-8 for Patients with Mild Symptomatic Heart Failure.

The Performance Measure for Activities of Daily Living-8 (PMADL-8) for patients with congestive heart failure is an International Classification of Functioning, Disability, and Health-based Activities of Daily Living (ICF) questionnaire to evaluate disease-specific functional limitations in chronic heart failure (CHF). The purpose of this study was to investigate the reliability and validity of the Turkish version of the PMADL-8 in CHF patients. In this study, 50 patients with CHF were included. Test-retest reliability of the PMADL-8 was assessed by intraclass correlation coefficient and Cronbach's alpha was calculated for internal consistency. Correlation coefficients between the PMADL-8 and New York Heart Association (NYHA) functional class, Chronic Heart Failure Questionnaire (CHQ), Nottingham Health Profile (NHP) were analyzed for construct validity. The Cronbach's alpha value of the PMADL-8 test and retest scores were recorded as 0.996, indicating that the scale is highly reliable. Test-retest reliability results of the PMADL-8 (mean intraclass correlation coefficient = 0.996) were excellent. The PMADL-8 score was moderately correlated with the NHP total score (r = 0.629, P < .001) and NHP physical abilities score (r = 0.517, P < .001). The PMADL-8 score was weakly correlated with the NYHA functional class (r = 0.385, P < .006), CHQ dyspnea (r = -0.475, P < .001), CHQ fatigue (r = -0.340, P = .016), and total score (r = -0.367, P = .009). The Turkish version of PMADL-8 is a reliable and valid assessment tool that could be used to determine activity limitations in CHF. The PMADL-8 is also useful for health professionals during the ICF evaluation of CHF patients.

Effect of empagliflozin on exercise ability and symptoms in heart failure patients with reduced and preserved ejection fraction, with and without type 2 diabetes.

The EMPERIAL (Effect of EMPagliflozin on ExeRcise ability and HF symptoms In patients with chronic heArt faiLure) trials evaluated the effects of empagliflozin on exercise ability and patient-reported outcomes in heart failure (HF) with reduced and preserved ejection fraction (EF), with and without type 2 diabetes (T2D), reporting, for the first time, the effects of sodium-glucose co-transporter-2 inhibition in HF with preserved EF (HFpEF). HF patients with reduced EF (HFrEF) (≤40%, N = 312, EMPERIAL-Reduced) or preserved EF (>40%, N = 315, EMPERIAL-Preserved), with and without T2D, were randomized to empagliflozin 10 mg or placebo for 12 weeks. The primary endpoint was 6-minute walk test distance (6MWTD) change to Week 12. Key secondary endpoints included Kansas City Cardiomyopathy Questionnaire Total Symptom Score (KCCQ-TSS) and Chronic Heart Failure Questionnaire Self-Administered Standardized format (CHQ-SAS) dyspnoea score. 6MWTD median (95% confidence interval) differences, empagliflozin vs. placebo, at Week 12 were -4.0 m (-16.0, 6.0; P = 0.42) and 4.0 m (-5.0, 13.0; P = 0.37) in EMPERIAL-Reduced and EMPERIAL-Preserved, respectively. As the primary endpoint was non-significant, all secondary endpoints were considered exploratory. Changes in KCCQ-TSS and CHQ-SAS dyspnoea score were non-significant. Improvements with empagliflozin in exploratory pre-specified analyses ofKCCQ-TSS responder rates, congestion score, and diuretic use in EMPERIAL-Reduced are hypothesis generating. Empagliflozin adverse events were consistent with those previously reported. The primary outcome for both trials was neutral. Empagliflozin was well tolerated in HF patients, with and without T2D, with a safety profile consistent with that previously reported in T2D. Hypothesis-generating improvements in exploratory analyses of secondary endpoints with empagliflozin in HFrEF were observed.

Health-related quality of life in outpatients with chronic heart failure associated with sideropenic anemia

The aim of this study was to assess the impact of anemia and iron deficiency on health-related quality of life (HRQoL) in outpatients with chronic congestive heart failure. The data were collected from patients with chronic congestive heart failure admitted to a university hospital outpatient clinic who agreed to be involved in the cross-sectional study. According to the World Health Organization’s cutoffs to define anemia, the patients were further divided into two groups, with and without anemia. HrQoL was assessed using two questionnaires: a disease-specific instrument, the chronic heart failure questionnaire (CHFQ), and a generic instrument, the Sickness Impact Profile (SIP). The standardized questionnaire was used to collect data regarding patients’ gender, age, marital status, place of living, education, occupation, and duration of diseases and comorbidities. To assess the iron status, ferritin, serum iron, the total iron binding capacity/TIBC and transferrin were measured. In total, 200 outpatients with congestive heart failure were included in the study, 100 with and 100 without anemia. Patients with anemia were mainly female, had longer duration of disease (p = 0.001) and more hospitalizations (p = 0.001). Independent associations were found between the HrQoL and hemoglobin level (p = 0.049), HrQoL and hematocrit value (p = 0.006) and HrQoL and NYHA functional class (p = 0.004). Iron deficiency was not associated with impaired HrQoL. Anemia has a significant impact on self-perceived health. Anemic patients are more likely to have worse heart failure as indicated by a higher NYHA class, thus being at higher risk for a decline of HrQoL compared with non-anemic patients.

Effects of a transitional palliative care model on patients with end-stage heart failure: study protocol for a randomized controlled trial.

BackgroundHeart failure (HF) is characterized by high rates of readmission after hospitalization, and readmission is a major contributor to healthcare costs. The transitional care model has proven efficacy in reducing the readmission rate and economic outcomes, and increasing satisfaction with care. However, the effectiveness of the transitional care model has not been evaluated in patients with end-stage HF. This study was designed to compare the customary hospital-based care and a comprehensive transitional care model, namely the Home-based Palliative HF Program (HPHP), in terms of readmission rate, quality of life, and satisfaction with care among end-stage HF patients under palliative care.Methods/designThis is a randomized controlled trial taking place in hospitals in Hong Kong. We have been recruiting patients with end-stage HF who are identified as appropriate for palliative care during hospitalization, on referral by their physicians. A set of questionnaires is collected from each participant upon discharge. Participants are randomized to receive usual care (customary hospital-based care) or the intervention (HPHP). The HPHP will be implemented for up to 12 months. Outcome measures will be performed at 1, 3, 6, and 12 months post-discharge. The primary outcome of this study is quality of life measured by the Chronic Heart Failure Questionnaire - Chinese version; secondary outcomes include readmission rate, symptom intensity, functional status, and satisfaction with care.DiscussionThis study is original and will provide important information for service development in the area of palliative care. The introduction of palliative care to end-stage organ failure patients is new and has received increasing attention worldwide in the last decade. This study adopts the randomized controlled trial, a vigorous research design, to establish scientific evidence in exploring the best model for end-stage HF patients receiving palliative care.Trial registrationThis trial was registered as NCT02086305 on 7 March 2014 in the United States Clinical Trials Registration, and in the Clinical Trials Registry, Hong Kong University with the trial number UW12202.Electronic supplementary materialThe online version of this article (doi:10.1186/s13063-016-1303-7) contains supplementary material, which is available to authorized users.

Assessing health-related quality of life in patients with heart failure: a systematic, standardized comparison of available measures

To systematically evaluate available health-related quality of life (HRQL) instruments for use in patients with heart failure (HF). Seven HF-specific HRQL questionnaires and associated studies of their metric properties were identified by systematic review: the Chronic Heart Failure Assessment Tool, the Cardiac Health Profile congestive heart failure, the Chronic Heart Failure Questionnaire (CHFQ), the Kansas City Cardiomyopathy Questionnaire (KCCQ), the Left Ventricular Disease Questionnaire (LVDQ), the Minnesota Living with Heart Failure Questionnaire (MLHFQ), and the Quality of Life in Severe Heart Failure Questionnaire. Each instrument was assessed by four experts using a standardized tool for evaluating patient-reported outcomes (EMPRO; scores from 0 to 100). Four questionnaires were given adequate scores (median >50) for the attribute "conceptual model." The LVDQ had the highest rated median for "reliability" (72.8). The CHFQ, the KCCQ, and the MLHFQ all got reasonable scores for "validity" (from 54.4 to 76.4). The reviewers rated the KCCQ the highest in terms of "sensitivity to change" (median 94.4). Only the CHFQ (50.0) and the KCCQ (72.2) received adequate scores for the "interpretability" attribute. The most highly rated instruments based on the overall EMPRO score were the KCCQ (64.4) and the MLHFQ (60.7), followed by the CHFQ (59.2). Based on the first systematic and reliable expert-based evaluation of available HF-specific HRQL questionnaires, the evidence seems to support the choice of the KCCQ, the MLHFQ, and the CHFQ over the others, which require further research on metric properties.

Evaluation of the Health Utilities Index Mark-3 in Heart Failure

Background The purpose of this study was to evaluate the reliability, validity, and responsiveness to change of the Health Utilities Index Mark-3 (HUI-3) in heart failure (HF) for use in cost-effectiveness studies. Methods and Results Two hundred eleven patients with HF recruited from outpatient clinics were enrolled; 165 completed the 26-week study. Patients completed 4 health-related quality of life questionnaires (baseline and 4, 8, and 26 weeks), including the HUI-3, the Medical Outcomes Study Short-form 12 (SF-12), the Minnesota Living with Heart Failure Questionnaire (LHFQ), and the Chronic Heart Failure Questionnaire (CHQ). The HUI-3 indicated moderate or fair health-related quality of life overall; the attributes most impaired were pain, ambulation, cognition, and emotion. Internal consistency reliability (Cronbach’s alpha = 0.51) was low and test-retest reliability (intraclass correlation coefficient = 0.68) was adequate. The HUI-3 total score was significantly associated with the SF-12, LHFQ, and CHQ total scores. It discriminated among patients with varying New York Heart Association class ( P < .001) and varying perceived health ( P < .001). The HUI-3 was less responsive to perceived change in health condition than the LHFQ or the CHQ. Conclusions The HUI-3 demonstrated satisfactory reliability and validity in this sample supporting its use in cost-effectiveness studies.

Reliability and validity of the Turkish version of the Chronic Heart Failure Questionnaire

Any disease specific Health Related Quality of Life Instrument for Chronic Heart Failure (CHF) is lacking in Turkey. The aim of this study is to adapt the Chronic Heart Failure Questionnaire (CHQ) into Turkish and probe the reliability and validity of this questionnaire. There are four dimensions of this 20 items scale. These dimensions are: dyspnea (5 items), fatigue (4 items), emotional status (7 items) and mastery (4 items). Response options were evaluated using a 7 -point Likert type scale. Quality of life (QOL) improves as the score increases. A total of 205 CHF patients hospitalized in the Department of Cardiology of Ege University hospital were enrolled in this study. The CHQ was applied to the patients twice with a wash-out period of 15 days. Confirmatory approach was used during the reliability and validity analysis. Cronbach alpha test was used for the reliability analysis. Confirmatory factor analysis (CFA) was used for the construct validity testing. NYHA classification for testing the criterion validity; SF-36 and WHOQOL-100 General Health and QOL facet for convergent validity testing of the Turkish version of the CHQ were used. Responsiveness to change was evaluated by Effect Size analysis by using test-retest data. The range of Cronbach alpha values is 0.72-0.94. A considerable ceiling and floor effects were observed for the dyspnea dimension of the scale but no problematic items were observed for the entire scale. The CFA results supported the original four factors scale structure. Criterion and construct validity rebuts were satisfactory. Effect sizes obtained among dimensions of the CHQ were between 0.13 and 0.56. Overall results revealed that Turkish version of the CHQ is a reliable and valid instrument to be used for the evaluation of CHF patients.

Impact of home-based, supervised exercise on congestive heart failure

Comparison of supervised home-based exercise program as adjunctive therapy, with comprehensive disease management alone, on symptoms and quality of life in congestive heart failure patients. 8 women and 11 men were enrolled in a randomized trial. The mean subject age was 69 (±4.44) in the controls and 70 (±4.05) in the intervention group. Baseline and 3, 6, and 12-month evaluations consisted of the Chronic Heart Failure Questionnaire (CHFQ), measuring perceived functional capacity (perceived symptoms of dyspnea, fatigue, and emotional function) and the Yale Physical Activity Survey (YPAS). A stress test was given at baseline and 12 months. The home-based exercise intervention caused a significant change in perceived fatigue between study groups (p=0.015), after 6 months of study participation, with the control group feeling less fatigued than the intervention group. After 12 months of participation, there were no significant differences in perceived functional capacity. Home-based exercise was well tolerated and favorably evaluated. This pilot study demonstrates the feasibility of studying home-based exercise in patients with moderate congestive heart failure. Larger and longer studies will be required to determine treatment effects.

Validity and Reliability of the Chronic Heart Failure Questionnaire Mastery Subscale in Patients With Defibrillators

Reliable, valid measures are needed to assess one's sense of mastery, which has the potential for decreasing anxiety and depressive symptoms among patients with implantable cardioverter-defibrillators (ICDs). This study evaluates the reliability and validity of a measure of mastery, the Chronic Heart Failure Questionnaire (CHQ) mastery subscale. One hundred twenty-two (75% men, mean age 65 years) and 100 patients complete baseline and 12-month face-to-face interviews, respectively. The CHQ mastery subscale is found to have internal consistency reliability (Cronbach's alphas = .79, .84), and its validity is supported. Factor analysis yields a single robust factor. Differences in the CHQ mastery subscale scores by the New York Heart Association (NYHA) classes are found: Patients with NYHA Class III or IV have lower mastery than those with Class I or II. Baseline younger age and less frequent ICD shocks and lower mastery are significant predictors of respectively 12-month anxiety (R( 2) = .37) and depressive symptoms (R(2) = .45).The CHQ mastery subscale has demonstrated satisfactory reliability and validity in this sample.

Disease-specific health-related quality of life questionnaires for heart failure: a systematic review with meta-analyses

Heart failure (HF) is an increasingly common condition affecting patients' health-related quality of life (HRQL). However, there is little literature comparing HF-specific instruments. Our aim was to evaluate and compare data on the conceptual model and metric properties (reliability, validity and responsiveness) of HF-specific HRQL instruments, by performing a systematic review with meta-analyses. Of 2,541 articles initially identified, 421 were full-text reviewed. Ninety-four reported data on five questionnaires: Minnesota Living with Heart Failure Questionnaire (MLHFQ), Chronic Heart Failure Questionnaire (CHFQ), Quality of Life Questionnaire for Severe Heart Failure (QLQ-SHF), Kansas City Cardiomyopathy Questionnaire (KCCQ) and Left Ventricular Dysfunction (LVD-36) questionnaire. Metric properties (reliability, validity and responsiveness) were summarised using meta-analysis for pools above five estimates. Cronbach's alpha coefficients were generally high (0.83-0.95) for overall scores and scales measuring physical health. Associations with four validity criteria (New York Heart Association [NYHA] class, six-minute walk test [6MWT] and short form-36 [SF-36] 'Physical' and 'Social Functioning') were moderate to strong (0.41-0.84), except for those between two CHFQ domains (fatigue and dyspnoea) and the NYHA (0.19 and 0.22). Pooled estimates of change from eight meta-analyses showed the MLHFQ to be highly responsive, with changes in overall score ranging from -9.6 (95% confidence interval [CI]: -4.1; -15.2) for placebo to -17.7 (95% CI: -15.3; -20.2) for pacing devices. The CHFQ and KCCQ also showed good sensitivity to change. Most of the questionnaires studied met minimum psychometric criteria, though current evidence would primarily support the use of the MLHFQ, followed by the KCCQ and CHFQ.

Triangulating Patient and Clinician Perspectives on Clinically Important Differences in Health‐Related Quality of Life among Patients with Heart Disease

To use triangulation methodology to better understand clinically important differences (CIDs) in the health-related quality of life (HRQoL) of patients with heart disease. We used three information sources: a nine-member expert panel, 656 primary care outpatients with coronary artery disease (CAD) and/or congestive heart failure (CHF), and the 46 primary care physicians (PCPs) treating these outpatients. From them, we derived CIDs for the Modified Chronic Heart Failure Questionnaire (CHQ) and the Medical Outcomes Study Short Form 36-Item Health Status Survey, Version 2 (SF-36). The expert physician panel employed Delphi and consensus methods to obtain CIDs. The outpatients received bimonthly HRQoL interviews for 1 year that included the CHQ and SF-36, as well as retrospective assessments of HRQoL changes. Their PCPs assessed changes in the patient's condition at follow-up clinic visits that were linked to HRQoL assessments to determine change over time. Patient- and PCP-assessed changes were categorized as trivial (no change), small, moderate, or large improvements or declines. Moderate or large changes in HRQoL reflect the added risk or investment associated with some treatment modifications. Estimates for each categorization were calculated by finding the mean change scores within anchored change classifications. The small CID for the CHQ domains was consistently one to two points using the patient-assessed change categorizations, but small CIDs varied greatly for the SF-36. PCP-assessed changes differed substantially from patient estimates for both the CHQ and SF-36, while the panel-derived estimates were generally larger than those derived from patients. Triangulation methodology provides a framework for securing a deeper understanding of each informant group's perspective on CIDs for these patient-reported outcome measures. These results demonstrate little consensus and suggest that the derived estimates depend on the rater and assessment methodology.

142 The CANPAP trial: Effects of CPAP on central sleep apnea, cardiovascular function and mortality in heart failure

peak), pulmonary artery pressures, markers of cardiac stretch (eg plasma brain natriuretic peptide), markers of catecholamines (e.g. plasma norepinephrine), and even resting heart rate! Unfortunately, none have proven to be a single stand alone variable upon which studies can be compared. Given the success of cardiac transplantation in the developed world, the term mortality in heart failure can be difficult to determine: should one use time of cardiac transplant as the end point, when a patient’s access to a cardiac transplant service is dependent upon socioeconomic, geographic, co-existentmedical problems or religious grounds?Quality of life is perhaps amore easily measurable index: standardised questionnaires either of heart failure severity (e.g. New York Heart Association, or the Gordon Guyatt Chronic Heart Failure Questionnaire), OSA, or general health (e.g. SF-36) specific are useful along with objective markers of cardiac function (pulmonary capillary wedge pressure, hospital admission frequency, 6 min walk distance). The role of sleep apnea (especially central sleep apnea with Cheyne Stokes respiration) is a useful marker of orthopnoea and paroxymal nocturnal dyspnoea, and accordingly, may be a useful marker of cardiac function over the long term.

Using an individualised quality of life measure in older heart failure patients

Background Existing tools purporting to measure quality of life in heart failure do not allow expression of individual needs and preferences. The Patient Generated Index is a recently introduced tool that allows individualised assessment of quality of life. Methods 59 patients aged 65 years and over with a clinical diagnosis of chronic heart failure were administered the Patient Generated Index at baseline, 1 week and 12 weeks, along with the Guyatt chronic heart failure questionnaire, Minnesota Living with Heart failure questionnaire and Short Form-12 tool. Changes in questionnaire scores were used to calculate reproducibility and responsiveness to change. Comparison of Patient Generated Index scores with the other questionnaires and with New York Heart Association class was used to determine construct validity. Results All four questionnaires were completed by > 90% of participants. Intraclass correlation coefficients denoting reproducibility were high for the Guyatt (0.93) and Minnesota questionnaires (0.89), moderate for the Patient Generated Index (0.65) and Short Form-12 (0.59). Responsiveness to change was similar for all questionnaires, but lower than in previous studies. The Patient Generated Index correlated with New York Heart association class and correlated moderately with the other questionnaires. The most important domains nominated on the Patient Generated Index were walking, performing daily activities, feeling tired and climbing stairs. Conclusions The Patient Generated Index can be administered successfully to older heart failure patients; usefulness is limited by suboptimal reproducibility and responsiveness. Impairment of physical function is the factor most cited by older heart failure patients affecting their quality of life.

Validation of the Chronic Heart Failure Questionnaire (Chinese version)

A striking rise in the incidence and prevalence of congestive heart failure (CHF) in the Chinese population has been reported. While promoting the quality of life (QOL) of these patients is widely recognized as an important clinical priority, there is not a validated Chinese disease-specific QOL measure for CHF patients. The aim of this study was to validate the Chinese version of Chronic Heart Failure Questionnaire (CHQ-C) which measures the disease-specific QOL of patients with CHF. A sample of 110 CHF elderly patients and a comparison group of 64 healthy elderly people was recruited. Structured questionnaires were administered by a research nurse. Criterion and construct validity of CHQ-C was demonstrated by its significant correlation with the New York Heart Association classification (Spearman r = -0.52, p < 0.001) and the Chinese version of Hospital Anxiety and Depression scale (Pearson r = -0.74, p < 0.001), respectively. Known-groups comparison also demonstrated the ability of CHQ-C to differentiate the QOL of people with or without CHF. Confirmatory factor analysis supported the original four-factor structure of CHQ. In terms of internal consistency and test-retest reliability, CHQ-C demonstrated a Cronbach's alpha of 0.95 and an intraclass correlation coefficient (ICC) of 0.75, respectively. The responsiveness coefficient of CHQ-C was 0.63. In conclusion, CHQ-C is recommended as a valid and reliable tool for evaluating the QOL of Chinese patients with CHF.

Clinically important differences in health status for patients with heart disease: an expert consensus panel report

Background The purpose of the study was to develop clinically important difference (CID) standards for patients with coronary artery disease and congestive heart failure that identify small, moderate, and large intraindividual changes with time in a modified version of the Chronic Heart Failure Questionnaire (CHQ) and the Medical Outcomes Study Short-Form 36-Item Health Survey (SF-36, version 2). Prior work in ascertaining important difference standards for the CHQ have centered on patient-perceived changes. No important difference standards for the SF-36 have been published for patients with heart disease. This development of CIDs would facilitate the use of health status measures in daily clinical decision-making. Methods We used a modification of the RAND Appropriateness Method to assemble and guide a 9-member consensus panel of physicians with substantial experience in using the CHQ or the SF-36 among patients with heart disease. Results On the basis of their own experience using these measures and an extensive review of articles describing the development and use of these instruments, the expert panel achieved consensus on small, medium, and large clinically relevant changes in scores for the CHQ and SF-36. The CID standards established by this panel were slightly higher than the minimal important difference standards previously established for the CHQ using patient-perceived changes. Conclusions The CID standards established by this expert panel provide an important and useful tool for determining whether routine clinical health status assessments will benefit patients and enhance physicians' decision-making capacity in clinical settings.

Relationship of Age and Sex to Health-Related Quality of Life in Patients With Heart Failure

Although health-related quality of life is diminished among patients with chronic heart failure, few investigators have examined interactions of age and sex with health-related quality of life longitudinally. To examine differences in health-related quality of life among 4 groups of patients with heart failure on the basis of age (< 65 years and > or = 65 years) and sex and to evaluate relationships of age and sex to changes in health-related quality of life during 6 months. Patients from 2 outpatient clinics in an urban county hospital were interviewed at baseline and 26 weeks later Health-related quality of life was measured by using the Minnesota Living With Heart Failure Questionnaire and the Chronic Heart Failure Questionnaire. A total of 165 patients (52% women; mean age, 57.6 years) completed interviews at baseline and 26 weeks later. At baseline, patients younger than 65 years had poorer health-related quality of life scores on total scales and some subscales than did older patients. Women had poorer scores than did men on some scales, particularly the emotional subscales. At 26 weeks, patients younger than 65 had poorer total health-related quality of life on 1 scale than did patients 65 and older, and women had poorer scores than did men on 1 total scale. With demographic and clinical factors controlled for, women younger than 65 had improvements in health-related quality of life on some scales. Women younger than 65 years had relatively poorer initial health-related quality of life that improved after 26 weeks.

Translation of the chronic heart failure questionnaire

The Brislin’s model of translation is recommended as the most reliable method for developing an equivalent translated instrument. This article describes its application in translating the Chronic Heart Failure Questionnaire (CHQ) from English to Chinese. The equivalence of translation of the CHQ is established. The methodological issues and difficulties encountered in the translation process are discussed.

Comparison of quality of life measures in heart failure

It is noticeable that the attention of clinical researchers worldwide is increasingly being focused upon the effects of heart failure, which in the past may not have had the attention given to other conditions. Despite a range of innovative treatments, morbidity and mortality rates in heart failure remain high. In this American study, the psychometric properties of three quality of life scales were compared. These were the Chronic Heart Failure Questionnaire (CHFQ), the Minnesota Living with Heart Failure Questionnaire (LHFQ), and the General Health Survey Short-form12 (SF-12). A convenience sample of 211 patients with heart failure completed baseline questionnaires via telephone interviews. Follow-up interviews were conducted at four, eight and 26 weeks. A total of 165 patients (78 per cent) completed the study, while 11 patients (5 per cent) died during the course of the research project. Overall, the results indicated that patients had a lowto-moderate health-related quality of life.

Social support and health-related quality of life in chronic heart failure patients.

Objectives of this study were to: (1) describe perceived social support during a baseline hospitalization and 12 months later among heart failure patients; (2) examine differences in social support as a function of gender and age (less than 65 and 65 years or older); and (3) examine social support as a predictor of health-related quality of life. Social support is a predictor of well-being and mortality, but little is known about support patterns among heart failure patients and how they influence quality of life. The sample included 227 hospitalized patients with heart failure who completed the Social Support Survey and the Chronic Heart Failure Questionnaire at baseline; 147 patients completed these questionnaires again 12 months after baseline. Mean baseline and 12-month total support scores were 56 and 53, respectively, with a score of 76 indicating the most positive perceptions of support. The ANOVA indicated significant interactions of gender by age for total (F = 5.04; p = 0.03) and emotional/informational support (F = 4.87; p = 0.03) and for positive social interactions (F = 4.43; p = 0.04), with men under age 65 perceiving less support than men aged 65 and older and women in either age group. Baseline support did not predict 12-month health-related quality of life, but changes in social support significantly predicted changes in health-related quality of life (R2 = 0.14). Overall, perceptions of support were moderate to high, but there was wide variation in perceptions over time. Men under age 65 reported less support than other groups of patients. Importantly, changes in social support were significant predictors of changes in health-related quality of life.
