Abstract
PURPOSE Health-related quality-of-life (HRQoL) data for the chronic heart failure (HF) population in Malaysia are lacking. Using EQ-5D-5L, this study intended to describe their HRQoL, identify predictors of worse HRQoL, and derive EQ-5D-5L index scores for use in economic evaluations. METHODS A cross-sectional survey was conducted between April and September 2023 to collect EQ-5D-5L, sociodemographic, and clinical data from outpatients with HF across seven public specialist hospitals in Malaysia. Multivariable logistic and linear regression models were used to identify independent predictors of reported problems in the EQ-5D-5L dimensions, and predictors of index scores and EQ-VAS, respectively. RESULTS EQ-5D-5L data from 424 outpatients of multi-ethnic background (mean age: 57.1 years, 23.8% female, mean left ventricular ejection fraction: 35.7%, 89.7% NYHA class I-II) were collected using either Malay, English, or Chinese, achieving a 99.8% completion rate. Nearly half of the respondents reported issues in the Mobility, Usual Activities, and Pain/Discomfort dimensions. Mean EQ-5D-5L index was 0.820, lower than the general population, and significantly lower with NYHA class III-IV (0.747) versus NYHA class I (0.846) and NYHA class II (0.805). Besides NYHA class, independent predictors of worse HRQoL included Indian ethnicity, living alone, lower education, unemployment due to ill-health, and proxy-reported HRQoL, largely aligning with existing literature. CONCLUSION Community-dwelling Malaysians with HF reported poorer HRQoL compared to the general population. The observed disparities in HRQoL among HF patients may be linked to specific patient characteristics, suggesting potential areas for targeted interventions. HRQoL assessment using EQ-5D-5L proves feasible and should be considered for routine implementation in local clinics.

Differences in Health-Related Quality of Life among Patients with Heart Failure. MEDICINA (KAUNAS, LITHUANIA) 2024; 60:109. [PMID: 38256370 PMCID: PMC10818915 DOI: 10.3390/medicina60010109] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/16/2023] [Revised: 12/20/2023] [Accepted: 01/04/2024] [Indexed: 01/24/2024]
Abstract
Heart failure (HF) is characterized by a progressive clinical course marked by frequent exacerbations and repeated hospitalizations, leading to considerably high morbidity and mortality rates. Patients with HF present with a constellation of bothersome symptoms, which range from physical to psychological and mental manifestations. With the transition to more advanced HF stages, symptoms become increasingly more debilitating, interfere with activities of daily living and disrupt multiple domains of life, including physical functioning, psychological status, emotional state, cognitive function, intimate relationships, lifestyle status, usual role activities, social contact and support. By inflicting profuse limitations in numerous aspects of life, HF exerts a profoundly negative impact on health-related quality of life (HRQOL). It is therefore not surprising that patients with HF display lower levels of HRQOL compared not only to the general healthy population but also to patients suffering from other chronic diseases. On top of this, poor HRQOL in patients with HF becomes an even greater concern considering that it has been associated with unfavorable long-term outcomes and poor prognosis. Nevertheless, HRQOL may differ significantly among patients with HF. Indeed, it has consistently been reported that women with HF display poorer HRQOL compared to men, while younger patients with HF tend to exhibit lower levels of HRQOL than their older counterparts. Moreover, patients presenting with higher New York Heart Association (NYHA) functional class (III-IV) have significantly more impaired HRQOL than those in a better NYHA class (I-II). Furthermore, most studies report worse levels of HRQOL in patients suffering from HF with preserved ejection fraction (HFpEF) compared to patients with HF with reduced ejection fraction (HFrEF) or HF with mildly reduced ejection fraction (HFmrEF). Last, but not least, differences in HRQOL have been noted depending on geographic location, with lower HRQOL levels having been recorded in Africa and Eastern Europe and higher in Western Europe in a recent large global study. Based on the observed disparities that have been invariably reported in the literature, this review article aims to provide insight into the underlying differences in HRQOL among patients with HF. Through an overview of currently existing evidence, fundamental differences in HRQOL among patients with HF are analyzed based on sex, age, NYHA functional class, ejection fraction and geographic location or ethnicity.

J Med Econ 2024; 27:607-617. [PMID: 38557412 DOI: 10.1080/13696998.2024.2337563] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2024] [Accepted: 03/28/2024] [Indexed: 04/04/2024]
Abstract
AIM This study aimed to examine the validity of EQ-5D-5L among HFrEF patients in Malaysia, and to explore the measurement equivalence of three main language versions. METHODS We surveyed HFrEF patients from two hospitals in Malaysia, using Malay, English or Chinese versions of EQ-5D-5L. EQ-5D-5L dimensional scores were converted to utility scores using the Malaysian value set. A confirmatory factor analysis longitudinal model was constructed. The utility and visual analog scale (VAS) scores were evaluated for validity (convergent, known-group, responsiveness), and measurement equivalence of the three language versions. RESULTS 200 HFrEF patients (mean age = 61 years), predominantly male (74%) of Malay ethnicity (55%), completed the admission and discharge EQ-5D-5L questionnaire in Malay (49%), English (26%) or Chinese (25%) languages. 173 patients (86.5%) were followed up at 1-month post-discharge (1MPD). The standardized factor loadings and average variance extracted were ≥ 0.5 while composite reliability was ≥ 0.7, suggesting convergent validity. Patients with older age and higher New York Heart Association (NYHA) class reported significantly lower utility and VAS scores. The change in utility and VAS scores between admission and discharge was large, while the change between discharge and 1MPD was minimal. The minimal clinically important difference for utility and VAS scores was ±0.19 and ±11.01, respectively. Malay and English questionnaire were equivalent while the equivalence of Malay and Chinese questionnaire was inconclusive. LIMITATION This study only sampled HFrEF patients from two teaching hospitals, thus limiting the generalizability of results to the entire heart failure population. CONCLUSION EQ-5D-5L is a valid questionnaire to measure health-related quality of life and estimate utility values among HFrEF patients in Malaysia. The Malay and English versions of EQ-5D-5L appear equivalent for clinical and economic assessments.

Abstract
Background In heart failure (HF), symptoms and health-related quality of life (HRQoL) are known to vary among different HF subgroups, but evidence on the association between changing HRQoL and outcomes has not been evaluated. Objectives The authors sought to investigate the relationship between changing symptoms, signs, and HRQoL and outcomes by sex, ethnicity, and socioeconomic status (SES). Methods Using the ASIAN-HF (Asian Sudden Cardiac Death in Heart Failure) Registry, we investigated associations between the 6-month change in a "global" symptoms and signs score (GSSS), Kansas City Cardiomyopathy Questionnaire overall score (KCCQ-OS), and visual analogue scale (VAS) and 1-year mortality or HF hospitalization. Results In 6,549 patients (mean age: 62 ± 13 years], 29% female, 27% HF with preserved ejection fraction), women and those in low SES groups had higher symptom burden but lower signs and similar KCCQ-OS to their respective counterparts. Malay patients had the highest GSSS (3.9) and lowest KCCQ-OS (58.5), and Thai/Filipino/others (2.6) and Chinese patients (2.7) had the lowest GSSS scores and the highest KCCQ-OS (73.1 and 74.6, respectively). Compared to no change, worsening of GSSS (>1-point increase), KCCQ-OS (≥10-point decrease) and VAS (>1-point decrease) were associated with higher risk of HF admission/death (adjusted HR: 2.95 [95% CI: 2.14-4.06], 1.93 [95% CI: 1.26-2.94], and 2.30 [95% CI: 1.51-3.52], respectively). Conversely, the same degrees of improvement in GSSS, KCCQ-OS, and VAS were associated with reduced rates (HR: 0.35 [95% CI: 0.25-0.49], 0.25 [95% CI: 0.16-0.40], and 0.64 [95% CI: 0.40-1.00], respectively). Results were consistent across all sex, ethnicity, and SES groups (interaction P > 0.05). Conclusions Serial measures of patient-reported symptoms and HRQoL are significant and consistent predictors of outcomes among different groups with HF and provide the potential for a patient-centered and pragmatic approach to risk stratification.

Xu J, Sun Y, Gong D, Fan Y. Association Between Disease-specific Health-related Quality of Life and All-cause Mortality in Patients with Heart Failure: A Meta-analysis. Curr Probl Cardiol 2023; 48:101592. [PMID: 36632931 DOI: 10.1016/j.cpcardiol.2023.101592] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Accepted: 01/03/2023] [Indexed: 01/09/2023]
Abstract
The association between disease-specific health quality of life (QoL) and adverse outcomes remains controversial in patients with heart failure (HF). This meta-analysis aimed to evaluate the association of QoL measured by the Minnesota Living with Heart Failure Questionnaire (MLHFQ) or Kansas City Cardiomyopathy Questionnaire (KCCQ) with all-cause mortality in patients with HF. PubMed and Embase databases were comprehensively searched until December 30, 2022 to identify studies investigating the utility of QoL measured by the MLHFQ or KCCQ in predicting all-cause mortality patients with HF. Twenty-five studies reported on 24 articles enrolling 42,414 HF patients were identified. A comparison of the top with the bottom MLHFQ score, the pooled adjusted hazard ratios (HR) of all-cause mortality was 1.56 (95% confidence intervals [CI] 1.26-1.94). When analyzed the MLHFQ as continuous variable, each 10-point MLHFQ score increase conferred a 12% (95% CI 6%-18%) higher risk of all-cause mortality, which was consistently significant for physical component (HR 1.19; 95% CI 1.09-1.30) and mental component (HR 1.21; 95% CI 1.05-1.40). A comparison of the bottom with the top KCCQ score, the pooled adjusted HR was 2.34 (95% CI 2.10-2.60) for all-cause mortality. Furthermore, each 10-point KCCQ score decrease was associated with a 12% (95% CI 7%-16%) higher risk of all-cause mortality. Worse health-related QoL defined by the higher MLHFQ or lower KCCQ score was associated with an increased risk of all-cause mortality in patients with HF. Assessment of disease-specific health QoL at baseline may provide important prognostic information in these patients.

Abstract
Background Frailty is common in patients with heart failure (HF) and can adversely impact outcomes. Objectives This study examined the prevalence of frailty among Asian patients with HF, its association with 1-year outcomes, and if race-ethnicity, HF subtypes, and sex modify this relationship. Methods In the multinational ASIAN-HF (Asian Sudden Cardiac Death in Heart Failure) registry, a baseline frailty index (FI) was constructed using a cumulative deficits approach with 48 baseline variables, and patients were followed for the 1-year primary outcome of all-cause death or HF hospitalization. Results Among 3,881 participants (age 61 ± 13 years, 27% female), the mean FI was 0.28 ± 0.11, and 69% were frail (FI >0.21). Higher FI was associated with older age, Malay ethnicity, and Southeast Asian residency. While comorbidities were more frequent in frail patients (by definition), body mass index was not different across frailty classes. Compared with FI class 1 (<0.21, nonfrail), FI class 2 (0.21-0.31) and FI class 3 (>0.31) had increased risk of the 1-year composite outcome (hazard ratios of 1.84 [95% confidence interval (CI): 1.42-2.38] and 4.51 [95% CI: 3.59-5.67], respectively), even after multivariable adjustment (adjusted hazard ratios of 1.49 [95% CI: 1.13-1.97] and 2.69 [95% CI: 2.06-3.50], respectively). Race-ethnicity modified the association of frailty with the composite outcome (Pinteraction = 0.0097), wherein the impact of frailty was strongest among Chinese patients. The association between frailty and outcomes did not differ between men and women (Pinteraction = 0.186) or for HF with reduced ejection fraction versus HF with preserved ejection fraction (Pinteraction = 0.094). Conclusions Most Asian patients with HF are frail despite relatively young age. Our results reveal specific ethnic (Malay) and regional (Southeast Asia) predisposition to frailty and highlight its prognostic importance, especially in Chinese individuals.

The Relationship Between Uncertainty in Illness and Quality of Life in Patients With Heart Failure: Multiple Mediating Effects of Perceived Stress and Coping Strategies. J Cardiovasc Nurs 2021; 37:257-265. [PMID: 33764941 DOI: 10.1097/jcn.0000000000000799] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 11/26/2022]
Abstract
BACKGROUND Previous investigators have demonstrated that uncertainty in illness is associated with quality of life (QoL) in patients with chronic illness. However, little is known about the mechanism underlying the relationship in patients with heart failure. OBJECTIVE The aim of this study was to examine the multiple mediating effects of perceived stress and coping strategies on the relationship between uncertainty in illness and QoL in patients with heart failure. METHODS We conducted a cross-sectional study in 302 patients with heart failure recruited at a general hospital in China from October 2016 to September 2017. Uncertainty in illness, perceived stress, coping strategies, and QoL were assessed using self-reported questionnaires. The multiple mediation model was tested using the PROCESS macro for SPSS. RESULTS Of the 302 patients, 51.7% had poor physical QoL and 45.7% had poor mental QoL (physical component summary or mental component summary score of <50 points). Uncertainty in illness had a significantly negative indirect effect on mental QoL through perceived stress and acceptance-resignation (indirect effect, -0.02; 95% confidence interval, -0.04 to -0.01). Uncertainty in illness also had a significantly negative indirect effect on mental QoL via perceived stress only (indirect effect, -0.18; 95% confidence interval, -0.26 to -0.09). CONCLUSIONS Poor QoL is prevalent in patients with heart failure. Perceived stress and acceptance-resignation are important mediating factors between uncertainty in illness and mental QoL in patients with heart failure. Interventions aimed at reducing perceived stress and acceptance-resignation coping may be beneficial for improving mental QoL in patients with heart failure.

Abstract
Background Optimizing quality of life (QoL) is a key priority in the management of heart failure (HF). Hypothesis To investigate ethnic differences in QoL and its association with 1‐year survival among patients with HF. Methods A prospective nationwide cohort (n = 1070, mean age: 62 years, 24.5% women) of Chinese (62.3%), Malay (26.7%) and Indian (10.9%) ethnicities from Singapore, QoL was assessed using the Minnesota Living with HF Questionnaire (MLHFQ) at baseline and 6 months. Patients were followed for all‐cause mortality. Results At baseline, Chinese had a lower (better) mean MLHFQ total score (29.1 ± 21.6) vs Malays (38.5 ± 23.9) and Indians (41.7 ± 24.5); P < .001. NYHA class was the strongest independent predictor of MLHFQ scores (12.7 increment for class III/IV vs I/II; P < .001). After multivariable adjustment (including NT‐proBNP levels, medications), ethnicity remained an independent predictor of QoL (P < .001). Crude 1‐year mortality in the overall cohort was 16.5%. A 10‐point increase of the physical component (of MLHFQ) was associated with a hazard (HR 1.22, 95% 1.03‐1.43) of 1‐year mortality (P = .018) in the overall cohort. An interaction between MLHFQ and ethnicity was found (P = .019), where poor MLHFQ score (per 10‐point increase) predicted higher adjusted mortality only in Chinese (total score: HR 1.18 [95% CI 1.07‐1.30]; physical: HR 1.44 [95% CI 1.17‐1.75]; emotional score: HR 1.45 [95% CI 1.05‐2.00]). Conclusions Ethnicity is an independent determinant of QoL in HF. Despite better baseline QoL in Chinese, QoL was more strongly related to survival in Chinese vs Malays and Indians. These findings have implications for HF trials that use patient‐reported outcomes as endpoints.
