Clinical profile and prognostic value of anemia at the time of admission and discharge among patients hospitalized for heart failure with reduced ejection fraction: findings from the EVEREST trial.

ABSTRACT: Anemia has been associated with worse outcomes in patients with chronic heart failure (HF). We aimed to characterize the clinical profile and postdischarge outcomes of hospitalized HF patients with anemia at admission or discharge.An analysis was performed on 3731 (90%) of 4133 hospitalized HF patients with ejection fraction ?40% enrolled in the Efficacy of Vasopressin Antagonist in Heart Failure Outcome Study with Tolvaptan (EVEREST) trial with baseline hemoglobin data, comparing the clinical characteristics and outcomes (all-cause mortality and cardiovascular mortality or HF hospitalization) of patients with and without anemia (hemoglobin <12 g/dL for women and <13 g/dL for men) on admission or discharge/day 7. Overall, 1277 patients (34%) were anemic at baseline, which persisted through discharge in 73% and resolved in 27%; 6% of patients without baseline anemia developed anemia by discharge or day 7. Patients with anemia were older, with lower blood pressure, and higher creatinine and natriuretic peptide levels compared with those without anemia (all P<0.05). After risk adjustment, anemia at discharge, but not admission, was independently associated with increased all-cause mortality (hazard ratio, 1.30; 95% confidence interval, 1.05-1.60; P=0.015; and hazard ratio, 0.94; 95% confidence interval, 0.76-1.15; P=0.53, respectively) and cardiovascular mortality plus HF hospitalization early postdischarge (?100 days; hazard ratio 1.73; 95% confidence interval, 1.37-2.18; P<0.001; and hazard ratio, 0.92; 95% confidence interval, 0.73-1.16; P=0.47, respectively). Neither baseline nor discharge anemia was associated with long-term cardiovascular mortality plus HF hospitalization (>100 days) on adjusted analysis (both P>0.1).Among hospitalized HF patients with reduced ejection fraction, modest anemia at discharge but not baseline was associated with increased all-cause mortality and short-term cardiovascular mortality plus HF hospitalization.URL: http://www.clinicaltrials.gov.

Project description:AIMS:Troponin levels are commonly elevated among patients hospitalized for heart failure (HF), but the prevalence and prognostic significance of early post-discharge troponin elevation are unclear. This study sought to describe the frequency and prognostic value of pre-discharge and post-discharge troponin elevation, including persistent troponin elevation from the inpatient to outpatient settings. METHODS AND RESULTS:The ASTRONAUT trial (NCT00894387; http://www.clinicaltrials.gov) enrolled hospitalized HF patients with ejection fraction ?40% and measured troponin I prior to discharge (i.e. study baseline) and at 1-month follow-up in a core laboratory (elevation defined as >0.04?ng/mL). This analysis included 1469 (91.0%) patients with pre-discharge troponin data. Overall, 41.5% and 29.9% of patients had elevated pre-discharge [median: 0.09?ng/mL; interquartile range (IQR): 0.06-0.19?ng/mL] and 1-month (median: 0.09?ng/mL; IQR: 0.06-0.15?ng/mL) troponin levels, respectively. Among patients with pre-discharge troponin elevation, 60.4% had persistent elevation at 1?month. After adjustment, pre-discharge troponin elevation was not associated with 12-month clinical outcomes. In contrast, 1-month troponin elevation was independently predictive of increased all-cause mortality [hazard ratio (HR) 1.59, 95% confidence interval (CI) 1.18-2.13] and cardiovascular mortality or HF hospitalization (HR 1.28, 95% CI 1.03-1.58) at 12?months. Associations between 1-month troponin elevation and outcomes were similar among patients with newly elevated (i.e. normal pre-discharge) and persistently elevated levels (interaction P???0.16). The prognostic value of 1-month troponin elevation for 12-month mortality was driven by a pronounced association among patients with coronary artery disease (interaction P?=?0.009). CONCLUSIONS:In this hospitalized HF population, troponin I elevation was common during index hospitalization and at 1-month follow-up. Elevated troponin I level at 1?month, but not pre-discharge, was independently predictive of increased clinical events at 12?months. Early post-discharge troponin I measurement may offer a practical means of risk stratification and should be investigated as a therapeutic target.

Project description:The relationship among anemia, renal dysfunction, left ventricular ejection fraction, and outcomes of patients hospitalized for acute decompensated heart failure is unclear. The aim of this study was to evaluate the association between cardiorenal anemia syndrome and postdischarge outcomes in patients hospitalized for heart failure with a preserved or reduced ejection fraction.Of 4842 patients enrolled in the Acute Decompensated Heart Failure Syndromes Registry between April 1, 2007 and December 31, 2011, 4393 patients were evaluated to investigate the association among anemia, renal dysfunction, preserved or reduced ejection fraction, and the primary end point (mortality and readmission for heart failure since discharge). The patients were divided into four groups on the basis of eGFR and hemoglobin at discharge. The median follow-up period after discharge was 432 (range=253-659) days.The primary end point was reached in 37.6% and 34.8% of the preserved and reduced ejection fraction groups, respectively. After adjustment for multiple comorbidities, there was no significant association of either renal dysfunction or anemia alone with the primary end point in patients with preserved ejection fraction, but the combination of renal dysfunction and anemia was associated with a significantly higher risk than that without either condition (hazard ratio, 1.54; 95% confidence interval, 1.12 to 2.12; P<0.01). In patients with reduced ejection fraction, adjusted analysis showed that a significantly higher risk of the primary end point was associated with renal dysfunction alone (hazard ratio, 1.65; 95% confidence interval, 1.21 to 2.25; P=0.002) and also, renal dysfunction plus anemia relative to the risk without either condition (hazard ratio, 2.19; 95% confidence interval, 1.62 to 2.96; P<0.001).The findings show that renal dysfunction combined with anemia is associated with an increased risk of adverse postdischarge outcomes in patients with preserved ejection fraction, whereas renal dysfunction is an independent predictor of the risk of adverse outcomes in patients with reduced ejection fraction, regardless of anemia.

Project description:Background Sacubitril/Valsartan has been highly efficacious in randomized trials of heart failure with reduced ejection fraction (HFrEF). However, the effectiveness of sacubitril/valsartan in older patients hospitalized for HFrEF in real-world US practice is unclear. Methods and Results This study included Medicare beneficiaries age ≥65 years who were hospitalized for HFrEF ≤40% in the Get With The Guidelines-Heart Failure registry between October 2015 and December 2018, and eligible for sacubitril/valsartan. Associations between discharge prescription of sacubitril/valsartan and clinical outcomes were assessed after inverse probability of treatment weighting and adjustment for other HFrEF medications. Overall, 1551 (10.9%) patients were discharged on sacubitril/valsartan. Of those not prescribed sacubitril/valsartan, 7857 (62.0%) were prescribed an angiotensin-converting enzyme inhibitor/angiotensin II receptor blocker. Over 12-month follow-up, compared with a discharge prescription of angiotensin-converting enzyme inhibitor/angiotensin II receptor blocker, sacubitril/valsartan was independently associated with lower all-cause mortality (adjusted hazard ratio [HR], 0.82; 95% CI, 0.72-0.94; P=0.004) but not all-cause hospitalization (adjusted HR, 0.97; 95% CI, 0.89-1.07; P=0.55) or heart failure hospitalization (adjusted HR, 1.04; 95% CI, 0.91-1.18; P=0.59). Patients prescribed sacubitril/valsartan versus those without a prescription had lower risk of all-cause mortality (adjusted HR, 0.69; 95% CI, 0.60-0.79; P<0.001), all-cause hospitalization (adjusted HR, 0.90; 95% CI, 0.82-0.98; P=0.02), but not heart failure hospitalization (adjusted HR, 0.94; 95% CI, 0.82-1.08; P=0.40). Conclusions Among patients hospitalized for HFrEF, prescription of sacubitril/valsartan at discharge was independently associated with reduced postdischarge mortality compared with angiotensin-converting enzyme inhibitor/angiotensin II receptor blocker, and reduced mortality and all-cause hospitalization compared with no sacubitril/valsartan. These findings support the use of sacubitril/valsartan to improve postdischarge outcomes among older patients hospitalized for HFrEF in routine US clinical practice.

Project description:ImportanceSacubitril-valsartan use reduces mortality and hospitalizations compared with enalapril among patients with chronic heart failure with reduced ejection fraction (HFrEF); however, the cost-effectiveness of these treatments when initiated during hospitalization for HF is unknown.ObjectiveTo estimate the cost-effectiveness of inpatient initiation of sacubitril-valsartan vs enalapril compared with no initiation or posthospitalization initiation of sacubitril-valsartan among stabilized patients with HFrEF.Design, setting, and participantsThis economic evaluation included data on US patients with HFrEF who were eligible for sacubitril-valsartan treatment from December 8, 2009, to May 15, 2018.Main outcomes and measuresA 5-state Markov model with all-cause mortality, HF, and non-HF hospitalization probabilities was used. Quality of life was estimated using Euro-QoL EQ-5D scores. Hospitalization, long-term care, and medication costs for sacubitril-valsartan and enalapril were modeled with a discount rate of 3%. The base-case analysis included a lifetime horizon from a health care and societal perspective.ResultsModeled patients were a mean (SD) age of 63.8 (11.5) years. Inpatient treatment with sacubitril-valsartan ($5628 per year) was associated with 62 fewer HF-related admissions per 1000 patients compared with outpatient initiation or 116 fewer HF-related admissions compared with continuation of enalapril treatment. From a health care system perspective, initiation of sacubitril-valsartan during hospitalization saved $452 per year compared with continuing enalapril and $811 per year compared with initiation at 2 months after hospitalization and was associated with an incremental cost-effectiveness ratio of $21 532 per quality-adjusted life-year compared with continued enalapril treatment over a lifetime. From a societal perspective, inpatient initiation was estimated to save $460 per year per patient compared with no initiation of sacubitril-valsartan and $813 per year per patient compared with initiation after hospitalization. In a budget analysis, inpatient initiation of sacubitril-valsartan was estimated to save up to $449 per person for 1 year or $2550 per person over 5 years compared with continuation of enalapril.Conclusions and relevanceThe findings suggest that, for patients with HFrEF, initiation of sacubitril-valsartan during hospitalization may be associated with reduced hospitalizations, increased quality-adjusted life expectancy, and cost savings compared with no initiation or initiation after hospitalization.

Project description:BackgroundThe evidence-based beta-blockers carvedilol, bisoprolol, and metoprolol succinate reduce mortality and hospitalizations among patients with heart failure with reduced ejection fraction (HFrEF). Use of these medications is not well described in the general population of patients with HFrEF, especially among patients with potential contraindications.ObjectivesOur goal was to describe the patterns of prescription fills for carvedilol, bisoprolol, and metoprolol succinate among Medicare beneficiaries hospitalized for HFrEF, as well as to estimate the associations between specific contraindications for beta-blocker therapy and those patterns.Methods and resultsWith the use of the cohort of 15,205 Medicare beneficiaries hospitalized for HFrEF from 2007 to 2013 in the 5% Medicare random sample, we described prescription fills (30 days after discharge) and dosage patterns (1 year after discharge) for beta-blockers. By means of of Fine and Gray competing risk models, we estimated the associations between potential contraindications (hypotension, chronic obstructive pulmonary disease [COPD], asthma, and syncope) and prescription fill and dosing patterns while adjusting for demographics, comorbidities, and health care utilization. For beneficiaries who did not die or readmitted to the hospital, 38% of hospitalizations were followed by a prescription fill for an evidence-based beta-blocker within 30 days, 12% were followed by prescription fills for at least 50% of the recommended dose of an evidence-based beta-blocker within 1 year, and 9% were followed by a prescription fill for an up-titrated dose of an evidence-based beta-blocker within 1 year. The prevalence of the contraindications were 21% for hypotension, 48% for COPD, 15% for asthma, and 12% for syncope. Among beneficiaries who did not fill a prescription for an evidence-based beta-blocker within 30 days, 67% had at least 1 of these contraindications. Hypotension, COPD, and syncope were each associated with a ∼10% lower risk of filling a prescription for an evidence-based beta-blocker.ConclusionsPrescription fill and up-titration rates for evidence-based beta-blockers are low among Medicare beneficiaries with HFrEF, but contraindications explain only a minor part of these low rates.
