Multinational and multiethnic variations in health-related quality of life in patients with chronic heart failure.

ABSTRACT: Assessing health-related quality of life (HRQoL) in patients with heart failure (HF) is an important goal of clinical care and HF research. We sought to investigate ethnic differences in perceived HRQoL and its association with mortality among patients with HF and left ventricular ejection fraction ?35%, controlling for demographic characteristics and HF severity.We compared 5697 chronic HF patients of Indian (26%), white (23%), Chinese (17%), Japanese/Koreans (12%), black (12%), and Malay (10%) ethnicities from the HF-ACTION and ASIAN-HF multinational studies using the Kansas City Cardiomyopathy Questionnaire (KCCQ; range 0-100; higher scores reflect better health status). KCCQ scores were lowest in Malay (58±22) and Chinese (60±23), intermediate in black (64±21) and Indian (65±23), and highest in white (67±20) and Japanese or Korean patients (67±22) after adjusting for age, sex, educational status, HF severity, and risk factors. Self-efficacy, which measures confidence in the ability to manage symptoms, was lower in all Asian ethnicities (especially Japanese/Koreans [60±26], Malay [66±23], and Chinese [64±28]) compared to black (80±21) and white (82±19) patients, even after multivariable adjustment (P<.001). In all ethnicities, KCCQ strongly predicted 1-year mortality (HR 0.45, 95% CI 0.30-0.67 for highest vs lowest quintile of KCCQ; P for interaction by ethnicity .101).Overall, HRQoL is inversely and independently related to mortality in chronic HF but is not modified by ethnicity. Nevertheless, ethnic differences exist independent of HF severity and comorbidities. These data may have important implications for future global clinical HF trials that use patient-reported outcomes as endpoints.

<h4>Background</h4>Assessing health-related quality of life (HRQoL) in patients with heart failure (HF) is an important goal of clinical care and HF research. We sought to investigate ethnic differences in perceived HRQoL and its association with mortality among patients with HF and left ventricular ejection fraction ≤35%, controlling for demographic characteristics and HF severity.<h4>Methods and results</h4>We compared 5697 chronic HF patients of Indian (26%), white (23%), Chinese (17%), Japan ...[more]

Project description:BackgroundWe have previously demonstrated an association between increased sFRP3 expression and adverse outcome in a population of HF irrespective of cause and left ventricular ejection fraction. In this study we evaluated the prognostic value of sFRP3 in older patients with chronic systolic HF of ischemic origin.MethodsWe evaluated sFRP3, by tertiles, as a risk factor for the primary endpoint (cardiovascular [CV] mortality, nonfatal myocardial infarction, nonfatal stroke), all-cause mortality, CV mortality, death from worsening HF (WHF), any coronary event, including sudden death, as well as hospitalizations for CV causes and WHF in 1444 patients from the CORONA population, randomly assigned to 10 mg rosuvastatin or placebo.ResultsKaplan-Meier curves for the primary endpoint, as well as all-cause- and CV mortality revealed a markedly better survival for patients with sFRP3 levels in the middle tertile of compared to the 1st and 3rd tertile. In multivariable Cox-regression, after full adjustment including high-sensitive CRP and NT-proBNP, a lower event rate for the primary end point, all cause and CV mortality was observed for patients with tertile 2 sFRP3 levels (HR 0.57 [0.44-0.74], 0.55 [0.44-0.74] and 0.52 [0.39-0.69]; p<0.001), as well as for the number of coronary events (HR 0.62 [0.47-0.82], p = 0.001) and sudden death (HR 0.55 [0.37-0.82], p = 0.002). Applying sFRP3 values to the fully adjusted regression model resulted in highly significant continuous net reclassification improvements for the primary endpoint, all cause and CV mortality, coronary events and sudden death (range 0.24-0.31; p≤0.002 for all).ConclusionsIntermediate serum sFRP3 levels are associated with better survival and fewer CV events than low or high sFRP3 levels, independently of conventional risk factors, in older patients with chronic systolic HF of ischemic origin. Our study suggests that balanced Wnt activity might confer protective effects in a clinical HF setting.Trial registrationhttp://www.clinicaltrials.gov NCT00206310.

Project description:BackgroundThere are calls to integrate serial recordings of health related quality of life (HRQoL) into routine care, clinical trials and prognosis. Little is known about the relationship between change in HRQoL and outcomes in heart failure (HF) patients by age, sex and HF subtype.MethodFrom the Swedish Heart Failure Registry (SwedeHF; 2008-2019), patients were categorised by reduced (<40%, HFrEF), mildly-reduced (40-49%, HFmrEF) and preserved (≥50%, HFpEF) ejection fraction. HRQoL was measured using Euro-QoL-5D visual analogue scale (EQ5D-vas), collected at baseline and 1-year. Baseline EQ5D-vas scores were categorised by: "best" (76-100), "good" (51-75), "bad" (26-50), and "worst" (0-25). Change in EQ5D-vas was categorised as 'no significant change' (<5 points increase/decrease); some worsening (5-9 points decrease); considerable worsening (≥10 points decrease); some improvement (5-9 points increase); considerable improvement (≥10 points increase). Associations with admission and death were estimated and interactions with patient sub-groups tested.FindingsAmong 23,553 patients (median age 74 [66-81] years, 8000 [34%] female), baseline EQ5D-vas was worse in older patients, women, and those with HFpEF compared to their respective counterparts. Compared to patients with the "best" EQ5D-vas, the adjusted associations for admission for those with "good", "bad" and "worst" EQ5D-vas were, respectively: HR 1.09 (1.04, 1.14), 1.27 (1.21, 1.33) and 1.39 (1.28, 1.51). Compared to no significant change in EQ5D-vas, the adjusted estimates for admission following some improvement, considerable improvement, some worsening and considerable worsening were, respectively: HR 0.91 (0.82, 1.01), 0.75 (0.70, 0.81), 1.04 (0.92, 1.16) and 1.25 (1.16, 1.35). Results were similar amongst groups and for HF admission and death.InterpretationChange in HRQoL was an independent indicator of risk of admission and death in people with all HF subtypes, irrespective of age and sex.FundingNIHR.
