Patient preferences for heart failure treatment: utilities are valid measures of health-related quality of life in heart failure.

BACKGROUND: Current standards hold that cost-effectiveness analyses should incorporate measures of both quantity and quality of life, and that quality of life in this context is best measured by a utility. We sought to measure utility scores for patients with heart failure and to assess their validity as measures of health-related quality of life (HRQL). METHODS AND RESULTS: We studied 50 patients with heart failure. We measured utilities with the time trade-off technique, exercise capacity with a 6-minute walk test, and HRQL with the Minnesota Living With Heart Failure questionnaire, the Medical Outcomes Study Short Form-36 (SF-36) questionnaire, and a visual analogue score. Validity was assessed by establishing correlation between utilities and these other measures. Mean utility score was 0.77 +/- 0.28. There were significant (P < .05) curvilinear relationships between utility score and visual analogue score, the physical function summary scale of the SF-36, 6-minute walk distance, and the Living With Heart Failure score. Utility scores on retest at 1 week were unchanged in a subset of 12 patients. Utilities did not vary systematically with age, sex, or ethnicity. CONCLUSION: Utilities are valid measures of HRQL in patients with heart failure, and cost-effectiveness analyses of heart failure treatments incorporating utilities in the outcome measure can be meaningful.     

Depressive symptom trajectory predicts 1-year health-related quality of life in patients with heart failure

Background

One-third of patients with heart failure (HF) experience depressive symptoms that adversely affect health-related quality of life (HRQOL). We aimed to describe depressive symptom trajectory and determine whether a change in depressive symptoms predicts subsequent HRQOL.

Methods and Results

The sample consisted of 256 inpatients and outpatients with HF. Depressive symptoms were measured at baseline and 3 or 6 months with the Patient Health Questionnaire (PHQ-9). The Minnesota Living with HF Questionnaire was used to assess HRQOL at baseline, 3 to 6 months, and 1 year. Based on baseline and 3- to 6-month PHQ-9 scores, patients were categorized as depressive symptom-free (64%), depressive symptoms improved (15%), depressive symptoms developed (6%), or persistent depressive symptoms (15%). The groups differed in 1-year HRQOL levels (F = 36, P < .001); patients who were depressive symptom-free or whose depressive symptoms improved had better 1-year HRQOL than patients with persistent depressive symptoms (Tukey honestly significant difference, P < .01). Change in depressive symptoms was the strongest predictor of 1-year HRQOL (standardized β = .42, P < .001), after controlling for functional status, demographics, and clinical variables.

Conclusions

We found the trajectory of depressive symptoms predicts future HRQOL. Research is needed to determine whether interventions targeting depressive symptoms improve HRQOL in patients with HF.     

Age, functional capacity, and health-related quality of life in patients with heart failure

BACKGROUND: Although heart failure disproportionately affects older persons and is associated with significant physical disability, existing data on physical limitations and health-related quality of life (HRQL) derive largely from studies of younger subjects. We compared the relationship between functional limitation and HRQL between older and younger patients with heart failure. METHODS AND RESULTS: We evaluated 546 outpatients with heart failure enrolled in a multicenter prospective cohort study. At baseline and 6 +/- 2 weeks later, functional status was assessed by New York Heart Association (NYHA) classification and 6-minute walk testing. HRQL was measured with the Kansas City Cardiomyopathy Questionnaire (KCCQ). Comparing older (age >65 years, n = 218) and younger patients (n = 328), we assessed baseline HRQL across strata of functional status. In the 484 patients who completed follow-up (194 older and 290 younger patients), we also assessed the changes in HRQL associated with changes in functional status over time. At baseline, older patients had better HRQL than younger patients (mean KCCQ score 60 +/- 25 versus 54 +/- 28, P = .005) in spite of worse NYHA class (mean 2.54 versus 2.35, P < .001) and lower 6-minute walk distances (824 +/- 378 versus 1064 +/- 371 feet, P < .001). After multivariable adjustment including baseline NYHA class, older age was independently correlated with better HRQL (beta = +7.9 points, P < .001). At follow-up, older patients with a deterioration in NYHA class experienced marked declines in HRQL compared with younger patients (mean HRQL change of -14.4 points versus +0.3 points, respectively, P < .001). Analyses using 6-minute walk distance as the functional measure yielded similar results. CONCLUSIONS: Although older patients with heart failure have relatively good HRQL in spite of significant functional limitations, they are at risk for worsening HRQL with further decline in functional status. These results underscore the importance of treatments aimed at maintaining functional status in older persons with heart failure, including those with significant baseline functional limitations.

Iron deficiency and health-related quality of life in chronic heart failure: Results from a multicenter European study

Patients affected by chronic heart failure (CHF) present significant impairment of health-related quality of life (HRQoL). Iron deficiency (ID) is a common comorbidity in CHF with negative impact in prognosis and functional capacity. The role of iron in energy metabolism could be the link between ID and HRQoL. There is little information about the role of ID on HRQoL in patients with CHF. We evaluate the impact of ID on HRQoL and the interaction with the anaemia status, iron status, clinical baseline information and HRQoL, measured with the Minnesota Living with Heart Failure questionnaire (MLHFQ) was obtained at baseline in an international cohort of 1278 patients with CHF. Baseline characteristics were median age 68 ± 12, 882 (69%) were males, ejection fraction was 38% ± 15 and NYHA class was I/II/III/IV (156/247/487/66). ID (defined as ferritin level < 100 µg/L or serum ferritin 100–299 µg/L in combination with a TSAT < 20%) was present in 741 patients (58%). 449 (35%) patients were anaemic. Unadjusted global scores of MLHFQ (where higher scores reflect worse HRQoL) were worse in ID and anaemic patients (ID +: 42 ± 25 vs. ID−: 37 ± 25; p-value = 0.001 and A+: 46 ± 25 vs. A−: 37 ± 25; p-value < 0.001). The combined influence of ID and anaemia was explored with different multivariable regression models, showing that ID but not anaemia was associated with impaired HRQoL. ID has a negative impact on HRQoL in CHF patients, and this is independent of the presence of anaemia.     

Effects of cardiac resynchronization therapy on health-related quality of life in older adults with heart failure

The aim of the study was to examine changes in health-related quality of life among older adults undergoing cardiac resynchronization therapy (CRT), a pacemaker based intervention for heart failure. Twenty-one patients (mean age = 68; SD = 8) completed measures of cardiovascular health and quality of life prior to and 3-months post-CRT. Following the intervention, patients reported improvements in their perception of their physical functioning (t = 2.8, p < 0.01) and feelings of vitality (t = 2.9, p < 0.01) on the MOS SF-36 Health Survey. Patients improved on objective clinical measures of exercise capacity, cardiac ejection fraction, and ventricular dyssynchrony. Younger patients reported greater improvements in physical functioning and decreases in pain. Higher baseline body mass index was associated with less improvement in physical functioning. Finally, patients with nonischemic heart failure reported greater improvements on multiple subscales of the SF-36 than patients with ischemic heart failure. This preliminary study documented improvements in health-related quality of life following CRT. The findings highlight that specific patient characteristics may be associated with quality of life changes. Future studies will benefit from including quality of life measures that assess multiple health-related domains.     

Correlates of health-related quality of life among lower-income, urban adults with congestive heart failure

BACKGROUND: Improving health-related quality of life (HRQL) is a primary goal in the treatment of patients with congestive heart failure (CHF), yet few studies have explored correlates of HRQL among CHF patients. OBJECTIVES: We report on the association of demographic and pathophysiologic measures, social-cognitive measures, and environmental variables with HRQL as measured by the Kansas City Cardiomyopathy Questionnaire (KCCQ), Chronic Heart Failure (CHQ), and a single question of perceived overall health (PH). METHODS: Cross-sectional data were obtained from the baseline interview and electronic medical records of 212 patients 50 years of age and older who were enrolled during the first 7 months of a medication adherence study. RESULTS: Mean age was 63; 32% were male; 53% were black; the mean Charlson comorbidity score was 3.7; and the mean New York Heart Association class was 2.1. Correlations between KCCQ and CHQ subscale scores and PH ranged from 0.16 to 0.37. Multivariate regression analyses showed that the pathophysiologic measures ejection fraction and comorbidity were not associated with any of the HRQL measures. Overall PH was associated with greater age and more positive health beliefs. Persons of greater age, males, and black respondents had higher CHF-specific HRQL scores, as did persons reporting more positive health beliefs, greater income, social support, and communication with their physician. Variance explained ranged from 14 to 33%. CONCLUSION: These cross-sectional data highlight the potential significance of social and behavioral factors in CHF-specific HRQL.     

Impact of sleep-related breathing disorders on health-related quality of life in patients with chronic heart failure

BACKGROUND: Quality of life in patients with chronic heart failure (HF) is often severely compromised. Sleep-related breathing disorders (SRBD) like Cheyne-Stokes Respiration (CSR) or obstructive sleep apnea (OSAS) are often observed in patients with severe HF resulting in fragmentation of sleep, excessive daytime sleepiness and an increased mortality. While an apnea/hypopnea-index (AHI) >30/h represents an independent predictor of poor prognosis, clinical relevance of even minor SRBD with an AHI <30/h remains unclear with respect to quality of life, exercise capacity or depression rate. METHODS: Sixty-nine consecutive ambulatory patients with stable HF (NYHA II-III, EF 25%) underwent two night polygraphies with a six-channel ambulatory recording. Spiroergometry was performed, and patients were examined for sleep quality (PSQI), depressed mood (BDI) and health-related quality of life (SF-36). The data were compared to 10 age-matched healthy controls and 11 patients with OSAS (AHI 14-29/h) not suffering from HF. RESULTS: Fifty-one patients completed follow up. 52% were positively diagnosed for SRBD (AHI 16-30/h: 12 patients CSR, 5 patients OSAS, 9 patients mixed); 25 patients (48%) showed no relevant SRBD. Patients with HF and SRBD had lower quality of life than patients without SRBD and HF. The severity of SRBD as indicated by the AHI significantly correlated with quality of life measures: Bodily pain, physical functioning and social functioning showed largest impairment in patients with HF and SRBD. Furthermore, elevated depression rates in correlation to the AHI were only observed in patients with SRBD similar to patients with OSAS without HF. CONCLUSION: Even minor SRBD in patients with HF independently influence quality of life and correlate with estimation of depression and sleep disturbances.     

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.     

Characterization of health-related quality of life in heart failure patients with preserved versus low ejection fraction in CHARM

BACKGROUND: Limited comparative studies assessing the health-related quality of life (HRQL) in heart failure (HF) patients with preserved vs. low ejection fraction (LVEF) have been disparate. AIMS: The aims of this study were a) to characterize HRQL in a large population of HF patients with preserved and low LVEF and b) to determine the factors associated with worse HRQL. METHODS: Patients with symptomatic HF (NYHA Class II-IV) enrolled in the Candesartan in Heart Failure: Assessment of Reduction in Mortality and Morbidity (CHARM) HRQL study completed the Minnesota Living with Heart Failure questionnaire at randomization. Patients were stratified into 2 HF cohorts: preserved LVEF (>40%) and low LVEF (相似文献   

Depression and health-related quality of life in elderly patients suffering from heart failure and their spouses: a comparative study

BACKGROUND: Little is known about the factors that influence the health outcome of elderly patients suffering from heart failure or the health of their spouses. The aim of this comparative study was to determine if older patients suffering from heart failure and their spouses experience similar levels of health-related quality of life (HRQOL) and depression. The aim was also to identify those factors that contribute to HRQOL and depression in patient-spouse pairs. METHODS: Data were collected from 47 couples, using the Short Form 36 (SF-36) and Zung Self-rating Depression Scale (SDS) questionnaires. RESULTS: Patients suffering from heart failure and their spouses differed significantly in their experience of the physical, but not the mental, health-related quality of life, with patients experiencing significantly worse physical functioning. Physical symptoms of heart failure seemed to dominate the experience of the patient and was positively related to mental health and inversely related to the New York Heart Association classification (NYHA class) and patients' depression. Depressive symptoms as reflected in SDS showed no significant difference between patients and spouses. Patients' depression was positively related to high NYHA class, while spouse depression was positively related with higher age of the patient. CONCLUSION: Physical symptoms seem to dominate the experience of heart failure.     

Changes in health-related quality of life in older patients with acute myocardial infarction or congestive heart failure: a prospective study

OBJECTIVES: To study changes in health-related quality of life (HR-QL) following acute myocardial infarction (AMI) or congestive heart failure (CHF) in older people (> or = 57 yr). DESIGN: Prospective cohort study. SETTING: Primary healthcare registers. PARTICIPANTS: Patients were enrolled on the basis of primary healthcare records. Eighty-nine AMI patients (mean age = 69.5) and 119 CHF patients (mean age = 74.5) were included for analysis. MEASUREMENTS: HR-QL was conceptualized and measured by means of physical (activities of daily living (ADL), instrumental activities of daily living (IADL)), psychological (depressive symptoms, anxiety), social, and role functioning. Premorbid data (TO) were available from a 1993 community-based survey. Incident AMI and CHF cases, developed after 1993, were prospectively followed for 12 months. Assessments were performed at 6 weeks (T1) and 6 (T2) and 12 months (T3) after diagnosis. RESULTS: At the premorbid assessment, AMI patients did not significantly differ on HR-QL from a reference group of older people, whereas CHF patients were on average older and had worse HR-QL compared to the reference group. Although CHF had not yet been diagnosed at TO, symptoms were already present and resulted in decreased levels of functioning. At T1, all HR-QL measures showed worse functioning compared with TO, except for depressive symptoms that presented later (at T2). In contrast to the delay in depressive symptoms, a significant increase in anxiety was already seen at T1. The effect of the somatic conditions was the largest on physical functioning. Effects on psychological and social functioning were less pronounced but still significant. Effects were maintained during the 12 months of follow-up. CONCLUSION: The negative consequences on HR-QL in both AMI and CHF patients are not temporary. No recovery of function was seen in AMI patients, and functioning of CHF patients continued to decline in the first year after diagnosis.     

A comparison of health-related quality of life between older adults with heart failure and healthy older adults

BACKGROUND: Health-related quality of life (HRQOL) in older adults with heart failure may be affected by a variety of variables including aging. It is important to determine the unique impact of heart failure to more effectively improve HRQOL in this population. OBJECTIVE: The purpose of this study was to compare HRQOL and physical, psychologic, clinical, and sociodemographic status in older adults with and without heart failure. METHODS: The HRQOL of 90 older adults with heart failure and 116 healthy older adults was compared. The factors best associated with HRQOL in each group were determined using multiple regression model. RESULTS: HRQOL was substantially worse among older adults with heart failure than among healthy older adults. Older adults with heart failure had more severe physical and emotional symptoms, poorer functional status, and worse health perceptions. Physical symptom status was the strongest predictor of HRQOL in both groups. In addition, in older adults with heart failure, physical symptom status, age, and anxiety were related to HRQOL. CONCLUSION: The poor HRQOL seen in patients with heart failure is not just a reflection of aging. Comprehensive interventions targeted toward the factors that specifically negatively impact HRQOL are essential in older adults with heart failure.

Patients with heart failure in primary health care: effects of a nurse-led intervention on health-related quality of life and depression

AIMS: To determine the effects of a nurse-led intervention designed to improve self-management of patients with heart failure in a primary health care setting regarding health-related quality of life and depression. METHODS: Patients at eight primary health care centres were screened by the Diagnosis Related Groups registry for the diagnosis of heart failure and eligibility for a cluster randomised study. A total of 153 patients were included (n=78 in the intervention group, 54% males, mean age 79 years, 59% in New York Heart Association class III-IV). The intervention involved patient and family education about heart failure and self-management and monthly telephone follow-up during 12 months by a primary health care nurse. RESULTS: The effects of the nurse-led intervention were limited. Significant differences were found in the physical dimension measured by the SF-36 health survey, and in depression measured by the Zung Self-rating Depression Scale. In comparison within groups at the 3 and 12-month follow-up, the intervention group significantly maintained their health-related quality of life measured by the SF-36 health survey, and their experience of depression measured by the Zung Self-rating Depression Scale to a greater extent than in the control group, especially among women. CONCLUSION: A nurse-led intervention directed toward patients with heart failure in a primary health care setting resulted in limited effects between the groups, although the physical and mental status were retained during 12 months of follow-up to a greater extent than in the control group.
