RESUMO

BACKGROUND: With emerging evidence on the efficacy of adding dapagliflozin to standard care for patients with heart failure with reduced ejection fraction (HFrEF), this study assessed the cost-effectiveness of add-on dapagliflozin to standard care versus standard care alone for HFrEF from the perspective of healthcare systems in the Asia-Pacific region. METHODS: A Markov model was applied to project the outcomes of treatment in terms of lifetime medical cost and quality-adjusted life-years. The transition probabilities between health states in the model were obtained from the Dapagliflozin in Patients with Heart Failure and Reduced Ejection Fraction trial. Country-specific costs and utilities were extracted for modeling. The incremental cost-effectiveness ratio against a country-specific willingness-to-pay threshold was applied to determine the cost-effectiveness of treatment. A series of sensitivity analyses were performed to ensure the robustness of the study results. Costs are presented in 2020 United States dollars. RESULTS: The incremental cost-effectiveness ratios for add-on dapagliflozin versus standard care alone were $5277, $9980, $12,305, $16,705, and $23,227 per quality-adjusted life-year gained in Korea, Australia, Taiwan, Japan, and Singapore, respectively. When using add-on dapagliflozin to standard care versus standard care alone, ~ 100% of simulations were cost-effective at a willingness-to-pay threshold of one gross domestic product per capita of the given Asia-Pacific country; however, the probability of being cost-effective for using add-on dapagliflozin decreased when the time horizon for simulation was restricted to 18 months and when the cardiovascular mortality for the two treatments (43.8% and 33.0%, respectively) was assumed to be the same. The cost-effectiveness results were most sensitive to cardiovascular mortality of treatment. CONCLUSIONS: Adding dapagliflozin to standard care is cost-effective for HFrEF in healthcare systems in the Asia-Pacific region, which supports the rational use of dapagliflozin for HFrEF in this region.

RESUMO

AIMS: Although obesity is associated with increased mortality, epidemiologic studies in heart failure have reported lower mortality in obese patients compared with matched nonobese patients (the 'obesity paradox'). However, the relationship between survival and extreme (morbid) obesity (BMI ≥ 40) is poorly understood. We evaluate survival in low ejection fraction patients across a range of BMI categories, including extreme obesity. METHODS: In a retrospective review, 12 181 consecutive patients receiving nuclear stress testing at a tertiary care center were stratified based on BMI and ejection fraction. Eight-year mortality data were collected using the social security death index. RESULTS: Normal ejection fraction patients (internal control, ejection fraction ≥50%) exhibited the J-shaped association between mortality and BMI that is observed in the general population. Among patients with reduced ejection fraction (<50%), survival improved as obesity increased (P < 0.0001). Those with extreme obesity had the lowest mortality (n = 1134, P < 0.05). CONCLUSION: In this cohort of reduced Ejection fraction patients, the obesity paradox was observed in all weight categories, with the highest survival of all observed in the extremely obese BMI category. This further supports hypotheses that an obesity-related physiologic phenomenon affects mortality in reduced ejection fraction patients.

RESUMO

BACKGROUND AND AIMS: Malnutrition is frequent in heart failure (HF). However, the best tool for evaluating malnutrition in geriatric patients with HF with reduced ejection fraction (HFrEF) is unknown. This study aimed to evaluate the incremental prognostic value of the geriatric nutritional risk index (GNRI) in stable geriatric outpatients with HFrEF compared with a clinical/laboratory prognostic model. METHODS AND RESULTS: A total of 143 outpatients with HFrEF, aged >65 years, a LVEF <40%, and who were stable and on optimal therapy were studied. Follow-up lasted 3 years. The outcome was all-cause death. The GNRI was calculated as follows: [(1.489 × serum albumin (g/L)) + (41.7 × (current body weight/ideal weight)]. The 3-year death rate was 36.4% and 16 (11.2%) patients were at risk of malnutrition (GNRI ≤98). Deceased patients had a lower GNRI (113.6 ± 9.1 vs. 105.6 ± 9.2; p < 0.001) than did survivors. Greater values of the GNRI (hazard ratio = 0.93, 95% confidence interval [CI] = 0.90-0.95; p < 0.001) and GNRI >98 (hazard ratio = 0.29, 95% CI 0.15-0.57; p < 0.001) were associated with better survival. These factors remained significant after adjustment of significant confounders. The GNRI was a better discriminator of death than weight and albumin. Adding the GNRI to the clinical/laboratory predictor survival model significantly increased the c-statistics from 0.93 to 0.95 (p < 0.001) and the chi-square likelihood ratio test from 106.15 to 119.9. CONCLUSION: The risk of malnutrition, as assessed by the GNRI, in stable geriatric outpatients with HFrEF is a strong independent predictor of survival. The GNRI adds significant prognostic information to the clinical/laboratory model.

RESUMO

BACKGROUND: B-type natriuretic peptide (BNP) and echocardiography are potentially useful adjunct to guide management of patients with chronic heart failure (HF).Thus, the aim of this retrospective, multicenter study was to compare outcomes and renal function in outpatients with chronic HF with reduced ejection fraction (HFrEF) who underwent an echo and BNP guided or a clinically driven protocol for follow-up. METHODS AND RESULTS: In 1137 consecutive outpatients, management was guided according to echo-Doppler signs of elevated left ventricular filling pressure and BNP levels conforming to the protocol of the Network Labs Ultrasound (NEBULA) in HF Study Group in 570 (mean EF=30%), while management was clinically driven based on the institutional protocol of the HF Unit of the Cardiovascular and Thoracic Department in 567 (mean EF=33%). Propensity score, matching several confounding baseline variables, was used to match pairs based on treatment strategy. The median follow-up was 37.4months. After propensity matching, a lower incidence of death (HR 0.45, 95%CI: 0.30-0.67, p<0.0001), and death or worsening renal function (HR 0.49, 95%CI 0.36-0.67, p<0.0001) was apparent in echo-BNP-guided group compared to clinically-guided group. Worsening of renal function (≥0.3mg/dl increase in serum creatinine) was observed in 9.8% of echo-BNP-guided group and in 21.4% of clinical assessed group (p<0.0001). The daily dose of loop diuretics did not change in echo-BNP-guided group, while it increased in 65% of patients in clinically-guided group (p<0.0001). CONCLUSIONS: Echo and BNP guided management may improve the outcome and reduce worsening of renal function in outpatients with chronic HFrEF.

RESUMO

OBJECTIVE: To evaluate the cost-effectiveness of implantable cardioverter defibrillators (ICDs), cardiac resynchronisation therapy pacemakers (CRT-Ps) and combination therapy (CRT-D) in patients with heart failure with reduced ejection fraction based on a range of clinical characteristics. METHODS: Individual patient data from 13 randomised trials were used to inform a decision analytical model. A series of regression equations were used to predict baseline all-cause mortality, hospitalisation rates and health-related quality of life and device-related treatment effects. Clinical variables used in these equations were age, QRS duration, New York Heart Association (NYHA) class, ischaemic aetiology and left bundle branch block (LBBB). A UK National Health Service perspective and a lifetime time horizon were used. Benefits were expressed as quality-adjusted life-years (QALYs). Results were reported for 24 subgroups based on LBBB status, QRS duration and NYHA class. RESULTS: At a threshold of £30 000 per QALY gained, CRT-D was cost-effective in 10 of the 24 subgroups including all LBBB morphology patients with NYHA I/II/III. ICD is cost-effective for all non-NYHA IV patients with QRS duration <120 ms and for NYHA I/II non-LBBB morphology patients with QRS duration between 120 ms and 149 ms. CRT-P was also cost-effective in all NYHA III/IV patients with QRS duration >120 ms. Device therapy is cost-effective in most patient groups with LBBB at a threshold of £20 000 per QALY gained. Results were robust to altering key model parameters. CONCLUSIONS: At a threshold of £30 000 per QALY gained, CRT-D is cost-effective in a far wider group than previously recommended in the UK. In some subgroups ICD and CRT-P remain the cost-effective choice.

RESUMO

BACKGROUND: Beta-blockers improve outcomes in patients with systolic heart failure. However, it is unknown whether their initial negative inotropic effect may increase 30-day all-cause readmission, a target outcome for Medicare cost reduction and financial penalty for hospitals under the Affordable Care Act. METHODS: Of the 3067 Medicare beneficiaries discharged alive from 106 Alabama hospitals (1998-2001) with a primary discharge diagnosis of heart failure and ejection fraction <45%, 2202 were not previously on beta-blocker therapy, of which 383 received new discharge prescriptions for beta-blockers. Propensity scores for beta-blocker use, estimated for each of the 2202 patients, were used to assemble a matched cohort of 380 pairs of patients receiving and not receiving beta-blockers who were balanced on 36 baseline characteristics (mean age 73 years, mean ejection fraction 27%, 45% women, 33% African American). RESULTS: Beta-blocker use was not associated with 30-day all-cause readmission (hazard ratio [HR] 0.87; 95% confidence interval [CI], 0.64-1.18) or heart failure readmission (HR 0.95; 95% CI, 0.57-1.58), but was significantly associated with lower 30-day all-cause mortality (HR 0.29; 95% CI, 0.12-0.73). During 4-year postdischarge, those in the beta-blocker group had lower mortality (HR 0.81; 95% CI, 0.67-0.98) and combined outcome of all-cause mortality or all-cause readmission (HR 0.87; 95% CI, 0.74-0.97), but not with all-cause readmission (HR 0.89; 95% CI, 0.76-1.04). CONCLUSIONS: Among hospitalized older patients with systolic heart failure, discharge prescription of beta-blockers was associated with lower 30-day all-cause mortality and 4-year combined death or readmission outcomes without higher 30-day readmission.

RESUMO

BACKGROUND: Clinical guidelines recommend digoxin for patients with symptomatic systolic heart failure (HF) receiving optimal medical therapy, but this recommendation is based on limited, older trial data. We evaluated the effectiveness and safety of digoxin in a contemporary cohort of patients with incident systolic HF. METHODS AND RESULTS: We identified adults with incident systolic HF between 2006 and 2008 within Kaiser Permanente Northern California who had no prior digoxin use. We used multivariable extended Cox regression to examine the association between new digoxin use and risks of death and HF hospitalization, controlling for medical history, laboratory results, medications, HF disease severity, and the propensity for digoxin use. We also conducted analyses stratified by sex and concurrent ß-blocker use. Among 2891 newly diagnosed patients with systolic HF, 529 (18%) received digoxin. During a median 2.5 years of follow-up, incident digoxin use was associated with higher rates of death (14.2 versus 11.3 per 100 person-years) and HF hospitalization (28.2 versus 24.4 per 100 person-years). In multivariable analysis, incident digoxin use was associated with higher mortality (hazard ratio, 1.72; 95% confidence interval, 1.25-2.36) but no significant difference in the risk of HF hospitalization (hazard ratio, 1.05; 95% confidence interval, 0.82-1.34). Results were similar in analyses stratified by sex and ß-blocker use. CONCLUSIONS: Digoxin use in patients with incident systolic HF was independently associated with a higher risk of death but no difference in HF hospitalization.

RESUMO

BACKGROUND: In patients with chronic heart failure, physical evaluation and clinical judgment may be inadequate for prognostic stratification. HYPOTHESIS: Information obtained with simple bedside tests would be helpful in patient management. METHODS: We report on 142 outpatients with systolic heart failure seen at our heart failure unit from 2007 to 2010 (ages 69.4 ± 8.9 years; ejection fraction [EF] 30.6 ± 6.1%; 43% with implanted defibrillators and/or resynchronization devices). At their first visit, we assessed levels of brain natriuretic peptide (BNP) (pg/mL), evaluated transthoracic conductance (TFC) (1/kΩ) by transthoracic bioimpedance, and performed echocardiography. RESULTS: Four-year mortality was 21.2%. At multivariate analysis, surviving and deceased subjects did not differ regarding New York Heart Association, age, gender, heart failure etiology, or EF at index visit. Patients who died had higher BNP and TFC (BNP = 884 ± 119 pg/mL vs 334 ± 110 pg/mL; TFC = 50 ± 8/kΩ vs 37 ± 7/kΩ, both P < 0.001]. Patients with BNP < 450 pg/mL and TFC < 40/kΩ had a 2.1% 4-year mortality, compared to 46.5% mortality of patients having BNP ≥ 450 pg/mL and TFC ≥ 40/kΩ. BNP ≥ 450 pg/mL and TFC ≥ 40/kΩ showed high sensitivity (91%) and specificity (88%)in identifying patients who died at follow-up. CONCLUSIONS: The combined use of BNP and impedance cardiography during the first assessment of a patient in a heart failure unit identified those carrying a worse medium-term prognosis. This approach could help the subsequent management of patients, allowing better clinical and therapeutic strategies.

RESUMO

BACKGROUND: The prevalence, health care consumption, and mortality increase in elderly patients with heart failure. This study aimed to analyse long term cost expenditure and predictors of health care consumption in these patients. METHODS: We included 208 patients aged 60 years or older and hospitalised with heart failure (NYHA class II-IV and left ventricular systolic dysfunction); 58% were men, mean age 76 years, and mean ejection fraction 0.34. Data on all hospital admissions, discharge diagnoses, lengths of stay, and outpatient visits were collected from the National Board of Health and Welfare. We obtained data of all health care consumption for each individual. RESULTS: After 8-12 years of prospective follow up 72% were dead (median survival 4.6 years). Main drivers of health care expenditure were non-cardiac (40%) and cardiac (29%) hospitalizations, and visits to primary care centres (16%), and hospital outpatient clinics (15%). On average, health care expenditures were € 36,447 per patient during follow up. The average yearly cost per patient was about 5,700€, in contrast to the estimated consumption of primary and hospital care in the general population: € 1,956 in 65-74 year olds and € 2,701 in 75-84 year olds. Poor quality of life (Nottingham Health Profile) was the strongest independent predictor of total health care consumption and costs (p<0.001; by multivariate analyses). CONCLUSION: Health care costs in chronic systolic heart failure are at least two-fold higher than in the general population. Quality of life is a strong independent predictor of health care consumption.

RESUMO

OBJECTIVE: Descriptions of the inpatient experience for patients hospitalized with systolic heart failure (HF) are limited and lack a cross-sectional representation of the US population. While length of stay (LOS) is a primary determinant of resource use and post-discharge events, few models exist for estimating LOS. RESEARCH DESIGN AND METHODS: MarketScan(®) administrative claims data from 1/1/2005-6/30/2008 were used to select hospitalized patients aged ≥18 years with discharge diagnoses for both HF (primary diagnosis) and systolic HF (any diagnostic position) without prior HF hospitalization or undergoing transplantation. RESULTS: Among 17,597 patients with systolic HF; 4109 had commercial; 2118 had Medicaid; and 11,370 had Medicare payer type. Medicaid patients had longer mean LOS (7.1 days) than commercial (6.3 days) or Medicare (6.7 days). In-hospital mortality was highest for patients with Medicaid (2.4%), followed by Medicare (1.3%) and commercial (0.6%). Commercial patients were more likely to receive inpatient procedures. Renal failure, pressure ulcer, malnutrition, a non-circulatory index admission DRG, receipt of a coronary artery bypass procedure or cardiac catheterization, or need for mechanical ventilation during the index admission were associated with increased LOS; receipt of a pacemaker device at index was associated with shorter LOS. LIMITATIONS: Selection of patients with systolic HF is limited by completeness and accuracy of medical coding, and results may not be generalizable to patients with diastolic HF or to international populations. CONCLUSION: Inpatient care, LOS, and in-hospital survival differ by payer among patients hospitalized with systolic HF, although co-morbidity and inpatient procedures consistently influence LOS across payer types. These findings may refine risk stratification, allowing for targeted intensive inpatient management and/or aggressive transitional care to improve outcomes and increase the efficiency of care.

RESUMO

BACKGROUND: Trials investigating efficacy of disease management programs (DMP) in heart failure reported contradictory results. Features rendering specific interventions successful are often ill defined. We evaluated the mode of action and effects of a nurse-coordinated DMP (HeartNetCare-HF, HNC). METHODS AND RESULTS: Patients hospitalized for systolic heart failure were randomly assigned to HNC or usual care (UC). Besides telephone-based monitoring and education, HNC addressed individual problems raised by patients, pursued networking of health care providers and provided training for caregivers. End points were time to death or rehospitalization (combined primary), heart failure symptoms, and quality of life (SF-36). Of 1007 consecutive patients, 715 were randomly assigned (HNC: n=352; UC: n=363; age, 69±12 years; 29% female; 40% New York Heart Association class III-IV). Within 180 days, 130 HNC and 137 UC patients reached the primary end point (hazard ratio, 1.02; 95% confidence interval, 0.81-1.30; P=0.89), since more HNC patients were readmitted. Overall, 32 HNC and 52 UC patients died (1 UC patient and 4 HNC patients after dropout); thus, uncensored hazard ratio was 0.62 (0.40-0.96; P=0.03). HNC patients improved more regarding New York Heart Association class (P=0.05), physical functioning (P=0.03), and physical health component (P=0.03). Except for HNC, health care utilization was comparable between groups. However, HNC patients requested counseling for noncardiac problems even more frequently than for cardiovascular or heart-failure-related issues. CONCLUSIONS: The primary end point of this study was neutral. However, mortality risk and surrogates of well-being improved significantly. Quantitative assessment of patient requirements suggested that besides (tele)monitoring individualized care considering also noncardiac problems should be integrated in efforts to achieve more sustainable improvement in heart failure outcomes.

RESUMO

BACKGROUND: Several studies that used claims and registry data have reported that 40% to 80% of patients eligible for an implantable cardioverter defibrillator (ICD) fail to receive one in clinical practice, and the rates are especially high among women and blacks. The extent and documented reasons for nonuse of ICDs among patients with left ventricular systolic dysfunction are unknown. METHODS AND RESULTS: Using hospital claims and clinical data, we identified patients hospitalized with a heart failure diagnosis and left ventricular ejection fraction ≤30% between January 1, 2007, and August 30, 2007, at a tertiary-care center. Using claims data, we determined placement of an ICD or cardiac resynchronization therapy with defibrillation device at any time up to 1 year after hospitalization. Medical records for patients without an ICD were abstracted to determine reasons for nonuse. Patients with an ICD were compared with patients without an ICD and also with patients without an ICD who did not have any contraindication for an ICD as identified through chart abstraction. Of the 542 potentially eligible patients identified, 224 (41%) did not have an ICD. In the initial adjusted analysis, female sex (odds ratio=1.90; 95% CI, 1.28 to 2.81) and increasing age (odds ratio=1.07; 95% CI, 1.04 to 1.11) were associated with a higher likelihood of not having an ICD. After detailed chart review, of the 224 patients without an ICD, 117 (52%) were ineligible for the device and 38 (17%) patients refused the device, resulting in only 69 (13%) patients eligible for an ICD who failed to receive one. In this subsequent adjusted analysis, remaining factors associated with a higher likelihood of not having an ICD were absence of ventricular arrhythmias (odds ratio=4.93; 95% CI, 2.56 to 9.50), noncardiology hospital service (odds ratio=3.73; 95% CI, 1.98 to 7.04), and lack of health insurance (odds ratio=3.10; 95% CI, 1.48 to 6.46). CONCLUSIONS: On the basis of a detailed chart review, the true rate of ICD underuse may be substantially lower than previous estimates. In addition, after accounting for ICD eligibility criteria, patient sex and age disparities in ICD therapy were no longer present.

RESUMO

BACKGROUND: Corin, a transmembrane serine protease expressed in cardiomyocytes, cleaves pro-atrial natriuretic peptide and pro-brain natriuretic peptide (BNP) into biologically active peptide hormones. The minor corin I555(P568) allele, defined by the T555I and Q568P mutations, is common in persons of African ancestry and associated with increased risk for hypertension and cardiac concentric hypertrophy. The corin gene product containing the T555I and Q568P mutations has significantly reduced natriuretic peptide processing capacity. We hypothesized that the corin I555(P568) allele would be associated with adverse outcomes and impaired BNP processing in blacks with systolic heart failure. METHODS AND RESULTS: This is a retrospective study of 354 subjects in the African American Heart Failure Trial Genetic Risk Assessment in Heart Failure substudy. In the corin variant group (n=50) compared with corin nonvariant group (n=300), BNP-32 (amino acids 77 to 108) was lower (190 pg/mL versus 340 pg/mL, P=0.007), but the ratio of unprocessed BNP(1 to 108)/processed BNP-32 was significantly higher (P=0.05). Stratified analyses were conducted because of evidence of significant interaction between the corin I555(P568) allele and treatment assignment. In the placebo arm, multivariable analysis demonstrated that the corin I555(P568) allele was associated with increased risk for death or heart failure hospitalization (relative risk 3.49; 95% CI, 1.45 to 8.39; P=0.005); however, in the treatment arm (fixed-dose combination isosorbide-dinitrate/hydralazine), the corin I555(P568) allele was not associated with adverse outcomes. CONCLUSIONS: We have identified a pharmacogenomic interaction in blacks with systolic heart failure. The corin I555(P568) allele is associated with an increased risk for death or heart failure hospitalization in patients receiving standard neurohormonal blockade, but the addition of fixed-dose combination isosorbide-dinitrate/hydralazine ameliorates this risk. A plausible mechanism for this pharmacogenomic interaction is the impaired processing of BNP in carriers of the corin I555(P568) allele as compared with noncarriers.

RESUMO

Metoprolol succinate, carvedilol, and bisoprolol are approved for use in heart failure. Other beta-blockers have been found to be inferior (metoprolol tartrate) or have not been studied (atenolol). The authors compared all-cause mortality following treatment with either atenolol, carvedilol, or metoprolol tartrate for 974 patients with left ventricular function < or =40%. The unadjusted mortality at 6 months was lower with atenolol (3.2%) and carvedilol (4.2%) when compared with metoprolol tartrate (7.5%, P< or =.039). However, patients with atenolol were older but had less prior heart failure. After adjustment for the propensity to be treated with atenolol, patients actually treated with atenolol had a significantly lower risk of death compared with treatment with metoprolol tartrate and comparable outcome to those treated with carvedilol. These results suggest that atenolol may be useful for patients with heart failure treatment and highlight the need for a randomized trial comparing atenolol with established beta-blockers.

RESUMO

BACKGROUND: Although higher blood pressures are generally recognised to be an adverse prognostic marker in risk assessment of cardiology patients, its relationship to risk in chronic heart failure (CHF) may be different. OBJECTIVE: To examine systematically published reports on the relationship between blood pressure and mortality in CHF. METHODS: Medline and Embase were used to identify studies that gave a hazard or relative risk ratio for systolic blood pressure in a stable population with CHF. Included studies were analysed to obtain a unified hazard ratio and quantify the degree of confidence. RESULTS: 10 studies met the inclusion criteria, giving a total population of 8088, with 29 222 person-years of follow-up. All studies showed that a higher systolic blood pressure (SBP) was a favourable prognostic marker in CHF, in contrast to the general population where it is an indicator of poorer prognosis. The decrease in mortality rates associated with a 10 mm Hg higher SBP was 13.0% (95% CI 10.6% to 15.4%) in the heart failure population. This was not related to aetiology, ACE inhibitor or beta blocker use. CONCLUSION: SBP is an easily measured, continuous variable that has a remarkably consistent relationship with mortality within the CHF population. The potential of this simple variable in outpatient assessment of patients with CHF should not be neglected. One possible application of this information is in the optimisation of cardiac resynchronisation devices.
