RESUMEN
Among the estimated 6.2 million Americans living with heart failure (HF), ≈5%/y may progress to advanced, or stage D, disease. Advanced HF has a high morbidity and mortality, such that early recognition of this condition is important to optimize care. Delayed referral or lack of referral in patients who are likely to derive benefit from an advanced HF evaluation can have important adverse consequences for patients and their families. A 2-step process can be used by practitioners when considering referral of a patient with advanced HF for consideration of advanced therapies, focused on recognizing the clinical clues associated with stage D HF and assessing potential benefits of referral to an advanced HF center. Although patients are often referred to an advanced HF center to undergo evaluation for advanced therapies such as heart transplantation or implantation of a left ventricular assist device, there are other reasons to refer, including access to the infrastructure and multidisciplinary team of the advanced HF center that offers a broad range of expertise. The intent of this statement is to provide a framework for practitioners and health systems to help identify and refer patients with HF who are most likely to derive benefit from referral to an advanced HF center.

BACKGROUND: We aimed to evaluate the influence of heart failure (HF) on clinical and economic outcomes among older adults ≥75 years of age during their acute myocardial infarction (AMI) admission in large population-based study from the United States. We also evaluated the clinical characteristics associated with the presence of HF and the predictors of mortality, healthcare utilization, and cost among older adults with AMI. METHODS: From January 1, 2000, to December 31, 2016, AMI admission was identified using the primary diagnosis and concomitant HF was identified using any non-primary diagnoses in the Premier Healthcare Database. RESULTS: Of the 468,654 patients examined, 42,946 (9%) had concomitant HF during their AMI admission. These patients were older, more often female, and were more likely to be White. Patients with concomitant HF were more likely to be frail than non-HF patients (59% vs 15%, P < .001). The mean (SD) Elixhauser comorbidity index was 2.6 (2.5) vs 0.4 (1.1), P < .001 in the AMI with HF vs AMI only group. The use of percutaneous coronary intervention in those with AMI and HF was lower than those with AMI only (15% vs 31%, P < .001). The overall mortality rate for those with HF was 12%, the median [IQR] hospital length of stay was 5 [3,9] days, and only 25% of patients were discharged home. A higher proportion of patients were discharged to rehabilitation or hospice if they had AMI and HF (Rehabilitation: 33% vs 20%, P < .001; Hospice: 5% vs 3%, P < .001). The mean unadjusted cost of an AMI hospitalization in patients with concomitant HF was lower ($12,411 ± $14,860) than in those without HF ($15,828 ± $19,330). After adjusting for age, gender, race, hypertension, frailty, revascularization strategy, and death, the average cost of hospitalization attributed to concomitant HF was +$1,075 (95% CI +876 to $1,274) when compared to AMI patients without HF. CONCLUSION: In patients ≥75 years of age, AMI with concomitant HF carries higher risk of death, but at ages ≥85 years, the risk difference diminishes due to other competing risks. HF was also associated with longer hospital length of stay and higher likelihood of referral to hospice and rehabilitation facilities when compared to older patients without HF. Care for these older adults is associated with increased hospitalization costs. Measures to identify HF in older adults during their AMI admission are necessary to optimize health outcomes, care delivery, and costs.

BACKGROUND: Health system-level interventions to improve use of guideline-directed medical therapy (GDMT) often fail in the acute care setting. We sought to identify factors associated with high performance in adoption of GDMT among health systems in CONNECT-HF. METHODS AND RESULTS: Site-level composite quality scores were calculated at discharge and last follow-up. Site performance was defined as the average change in score from baseline to last follow-up and analyzed by performance tertile using a mixed-effects model with baseline performance as a fixed effect and site as a random effect. Among 150 randomized sites, the mean 12-month improvement in GDMT was 1.8% (-26.4% to 60.0%). Achievement of 50% or more of the target dose for angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, angiotensin receptor-neprilysin inhibitors, and beta-blockers at 12 months was modest, even at the highest performing sites (median 29.6% [23%, 41%] and 41.2% [29%, 50%]). Sites achieving higher GDMT scores had care teams that included social workers and pharmacists, as well as patients who were able to afford medications and access medication lists in the electronic health record. CONCLUSIONS: Substantial gaps in site-level use of GDMT were found, even among the highest performing sites. The failure of hospital-level interventions to improve quality metrics suggests that a team-based approach to care and improved patient access to medications are needed for postdischarge success.

Importance: Adoption of guideline-directed medical therapy for patients with heart failure is variable. Interventions to improve guideline-directed medical therapy have failed to consistently achieve target metrics, and limited data exist to inform efforts to improve heart failure quality of care. Objective: To evaluate the effect of a hospital and postdischarge quality improvement intervention compared with usual care on heart failure outcomes and care. Design, Setting, and Participants: This cluster randomized clinical trial was conducted at 161 US hospitals and included 5647 patients (2675 intervention vs 2972 usual care) followed up after a hospital discharge for acute heart failure with reduced ejection fraction (HFrEF). The trial was performed from 2017 to 2020, and the date of final follow-up was August 31, 2020. Interventions: Hospitals (n = 82) randomized to a hospital and postdischarge quality improvement intervention received regular education of clinicians by a trained group of heart failure and quality improvement experts and audit and feedback on heart failure process measures (eg, use of guideline-directed medical therapy for HFrEF) and outcomes. Hospitals (n = 79) randomized to usual care received access to a generalized heart failure education website. Main Outcomes and Measures: The coprimary outcomes were a composite of first heart failure rehospitalization or all-cause mortality and change in an opportunity-based composite score for heart failure quality (percentage of recommendations followed). Results: Among 5647 patients (mean age, 63 years; 33% women; 38% Black; 87% chronic heart failure; 49% recent heart failure hospitalization), vital status was known for 5636 (99.8%). Heart failure rehospitalization or all-cause mortality occurred in 38.6% in the intervention group vs 39.2% in usual care (adjusted hazard ratio, 0.92 [95% CI, 0.81 to 1.05). The baseline quality-of-care score was 42.1% vs 45.5%, respectively, and the change from baseline to follow-up was 2.3% vs -1.0% (difference, 3.3% [95% CI, -0.8% to 7.3%]), with no significant difference between the 2 groups in the odds of achieving a higher composite quality score at last follow-up (adjusted odds ratio, 1.06 [95% CI, 0.93 to 1.21]). Conclusions and Relevance: Among patients with HFrEF in hospitals randomized to a hospital and postdischarge quality improvement intervention vs usual care, there was no significant difference in time to first heart failure rehospitalization or death, or in change in a composite heart failure quality-of-care score. Trial Registration: ClinicalTrials.gov Identifier: NCT03035474.

Following regulatory guidance set forth in 2008 by the US Food and Drug Administration for new drugs for type 2 diabetes mellitus, many large randomized, controlled trials have been conducted with the primary goal of assessing the safety of antihyperglycemic medications on the primary end point of major adverse cardiovascular events, defined as cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke. Heart failure (HF) was not specifically mentioned in the US Food and Drug Administration guidance and therefore it was not a focus of these studies when planned. Several trials subsequently showed the impact of antihyperglycemic drugs on HF outcomes, which were not originally specified as the primary end point of the trials. The most impressive finding has been the substantial and consistent risk reduction in HF hospitalization seen across 4 trials of sodium glucose cotransporter 2 inhibitors. However, to date, these results have not led to regulatory approval of any of these drugs for a HF indication or a recommendation for use by US HF guidelines. It is therefore important to explore to what extent persuasive treatment effects on nonprimary end points can be used to support regulatory claims and guideline recommendations. This topic was discussed by researchers, clinicians, industry sponsors, regulators, and representatives from professional societies, who convened on the US Food and Drug Administration campus on March 6, 2019. This report summarizes these discussions and the key takeaway messages from this meeting.

Many therapies have been shown to improve outcomes for patients with heart failure (HF) in controlled settings, but there are limited data available to inform best practices for hospital and post-discharge quality improvement initiatives. The CONNECT-HF study is a prospective, cluster-randomized trial of 161 hospitals in the United States with a 2×2 factorial design. The study is designed to assess the effect of a hospital and post-discharge quality improvement intervention compared with usual care (primary objective) on HF outcomes and quality-of-care, as well as to evaluate the effect of hospitals implementing a patient-level digital intervention compared with usual care (secondary objective). The hospital and post-discharge intervention includes audit and feedback on HF clinical process measures and outcomes for patients with HF with reduced ejection fraction (HFrEF) paired with education to sites and clinicians by a trained, nationally representative group of HF and quality improvement experts. The patient-level digital intervention is an optional ancillary study and includes a mobile application and behavioral tools that are intended to facilitate improved use of guideline-directed recommendations for self-monitoring and self-management of activity and medications for HFrEF. The effects of the interventions will be measured through an opportunity-based composite score on quality and time-to-first HF readmission or death among patients with HFrEF who present to study hospitals with acute HF and who consent to participate. The CONNECT-HF study is evaluating approaches for implementing HF guideline recommendations into practice and is one of the largest HF implementation science trials performed to date.

Incidence of Burkitt's lymphoma post-transplant lymphoproliferative disorder (BL-PTLD) in solid organ transplant (SOT) recipients in 1.4%-1.6% with unknown cure rate. We report a case of Epstein-Barr virus (EBV) positive, late-onset BL-PTLD in a 24-year-old EBV donor positive/recipient negative female. This is the first reported case of advanced BL-PTLD post-heart transplant in an adult. This is also the first reported case of treatment of advanced BL-PTLD in a heart transplant recipient with a combined chemotherapy regimen without anthracyclines to avoid cardiotoxicity. The patient received 6 cycles of R-COEP (rituximab with cyclophosphamide, vincristine, etoposide, prednisone) over 6 months and subsequently 3 cycles of high-dose methotrexate (MTX) over 3 months for CNS prophylaxis. She remains without evidence of disease at 19 months post-treatment. This case demonstrates that an anthracycline-free regimen can be the therapy option for patients with BL-PTLD after heart transplantation.

Heart failure (HF) and diabetes mellitus (DM) are major public health issues that place significant burden on patients and health care systems. Patients with both HF and DM are at higher risk of adverse cardiovascular and HF outcomes than those with either disease in isolation. Different antihyperglycemic medications (even within the same medication class) have conflicting results of benefit or harm in patients with established and incident HF. Recent data highlight the importance of a renewed focus on optimal pharmacotherapy for this population with DM and HF (or at risk for HF). Both HF and DM require major lifestyle modification for optimal management, in terms of both optimizing health behaviors (eg, physical activity, diet) and adherence to complex medical and self-care regimens. Mobile health (mHealth) technologies (eg, apps, wearables) are widely available in the community and may play a role in optimizing the health status of patients; however, there is limited and conflicting information on whether such technologies are actually beneficial in at-risk populations. In this article, we summarize current strategies, including mobile health interventions, to improve physical activity levels, drug adherence, and outcomes in patients with DM, HF, or both and describe the design and rationale for the Technologies to improve drug Adherence and Reinforce Guideline based Exercise Targets in patients with heart Failure and Diabetes Mellitus trial, which is designed to test the efficacy of using mHealth technology to improve health behaviors and outcomes in this high-risk population.

INTRODUCTION: Worsening renal function (WRF) can occur throughout a hospitalization for acute heart failure (HF). However, decongestion can be measured in different ways and the prognostic implications of WRF in the setting of different measures of decongestion are unclear. METHODS: Patients (N = 433) from the ESCAPE were classified by measures of decongestion during hospitalization: hemodynamic (right atrial pressure ≤8 mmHg and/or wedge pressure ≤15 mmHg at discharge), clinical (≤1 sign of congestion at discharge), hemoconcentration (any increase in hemoglobin) and estimated plasma volume using the Hakim formula (5% reduction in plasma volume). WRF was defined as creatinine increase ≥0.3 mg/dl during hospitalization. The association between WRF and 180-day all-cause death was assessed. RESULTS: Successful decongestion was observed in 124 (60%) patients by hemodynamics, 204 (49%) by clinical exam, 173 (47%) by hemoconcentration, and 165 (45%) by plasma volume. There was no agreement between the hemodynamic assessment and other decongestion measures in up to 43% of cases. Persistent congestion with concomitant WRF at discharge was associated with worse outcomes compared to patients without congestion and WRF. Among patients decongested at discharge, in-hospital WRF was not significantly associated with 180-day all-cause death, when using hemodynamic, clinical or estimated plasma volume as measures of decongestion (P > .05 for all markers). CONCLUSIONS: In patients hospitalized for HF, although there was disagreement across common measures of decongestion, in-hospital WRF was not associated with increased hazard of all-cause mortality among patients successfully decongested at discharge.

BACKGROUND: Deaths from drug intoxication have increased in the United States but outcomes of recipients of orthotopic heart transplantation (OHT) from these donors are not well characterized. METHODS: We performed a retrospective analysis of the United Network for Organ Sharing's STAR database between January 2000 and March 2014 and assessed mortality and retransplantation using adjusted Cox models by mechanism of donor death. RESULTS: Of the 31,660 OHTs from 2000 to 2014, 1233 (3.9%) were from drug intoxication. These donors were more likely to be female, white, with greater tobacco use and higher BMI compared to donors who died of other mechanisms. Drug intoxication accounted for 1.1% of OHT donors in 2000 and 6.2% in March 2014. No significant difference was observed in 10-year mortality (adjusted hazard ratio [HR], 95% confidence interval [CI]: 0.99, 0.87-1.13), 10-year retransplantation (adjusted HR 0.84, 0.49-1.41) or 1-year and 3-year rehospitalization with other mechanisms of death compared to drug intoxication. CONCLUSION: There has been a large increase in OHT donors who die of drug intoxication in the United States. OHT outcomes from these donors are similar to those dying from other mechanisms. These data have important implications for donor selection in context of the ongoing opioid epidemic.

AIMS: To explore the association of changes in weight and fluid during treatment for acute heart failure (AHF) with clinical endpoints. METHODS AND RESULTS: Weight and net fluid changes recorded at 72-96 hours in 708 AHF patients enrolled in Diuretic Optimization Strategy Evaluation in Acute Decompensated Heart Failure, Cardiorenal Rescue Study in Acute Decompensated Heart Failure, and Renal Optimization Strategies Evaluation in Acute Heart Failure studies were compared with freedom from congestion at 72-96 hours and a composite endpoint of death, rehospitalization, and unplanned hospital visit at 60 days. Weight loss was concordant with net fluid loss in 55%, discordant and less than expected for fluid loss in 34%, and paradoxically discordant or more than expected for fluid loss in 11% of patients. Weight loss, but not fluid loss, was associated with freedom from congestion (odds ratio per 1-kg weight loss = 1.11 [1.03-1.19]) and a nominal reduction in the composite endpoint (hazard ratio per 1-kg weight loss = 0.98 [0.95-1.00]). Outcomes were similar in patients with concordant and discordant weight-fluid loss. CONCLUSION: During treatment for AHF, early changes in weight may be more useful for identifying response to therapy and for predicting outcomes than net fluid output. Nearly one-half of patients receiving decongestive therapies demonstrate discordant changes in weight and fluid; however, discordance was not associated with outcomes.

BACKGROUND: A subset of patients hospitalized with acute heart failure experiences in-hospital worsening heart failure, defined as persistent or worsening signs or symptoms requiring an escalation of therapy. METHODS: We analyzed data from the Acute Decompensated Heart Failure National Registry (ADHERE) linked to Medicare claims to develop and validate a risk model for in-hospital worsening heart failure. Our definition of in-hospital worsening heart failure included events such as escalation of medical therapy (eg, inotropic medications) >12hours after admission. We considered candidate risk prediction variables routinely assessed at admission, including age, medical history, biomarkers, and renal function. We used logistic regression with robust standard errors to generate a risk model in a 66% random derivation sample; we validated the model in the remaining 34%. We evaluated the calibration and discrimination of the model in both samples. RESULTS: We evaluated 23,696 patients hospitalized with acute heart failure. Baseline characteristics were well matched in the derivation and validation samples, and the occurrence of in-hospital worsening heart failure was similar in both samples (15.4% and 15.6%, respectively). In the multivariable model, the strongest predictors of in-hospital worsening heart failure were increased troponin and creatinine. The model was well calibrated and had good discrimination in the derivation sample (c statistic, 0.74) and validation sample (c statistic, 0.72). CONCLUSIONS: The ADHERE worsening heart failure risk model is a clinical tool with good discrimination for use in patients hospitalized with acute heart failure to identify those at increased risk for in-hospital worsening heart failure. This tool may be useful to target treatment strategies for patients at high risk for in-hospital worsening heart failure.

BACKGROUND: Though commonly noted in clinical practice, it is unknown if decongestion in acute heart failure (AHF) results in increased serum bicarbonate. METHODS AND RESULTS: For 678 AHF patients in the DOSE-AHF, CARRESS-HF, and ROSE-AHF trials, we assessed change in bicarbonate (baseline to 72-96 hours) according to decongestion strategy, and the relationship between bicarbonate change and protocol-defined decongestion. Median baseline bicarbonate was 28 mEq/L. Patients with baseline bicarbonate ≥28 mEq/L had lower ejection fraction, worse renal function and higher N-terminal pro-B-type natriuretic peptide than those with baseline bicarbonate <28 mEq/L. There were no differences in bicarbonate change between treatment groups in DOSE-AHF or ROSE-AHF (all P > .1). In CARRESS-HF, bicarbonate increased with pharmacologic care but decreased with ultrafiltration (median +3.3 vs -0.9 mEq/L, respectively; P < .001). Bicarbonate change was not associated with successful decongestion (P > .2 for all trials). CONCLUSIONS: In AHF, serum bicarbonate is most commonly elevated in patients with more severe heart failure. Despite being used in clinical practice as an indicator for decongestion, change in serum bicarbonate was not associated with significant decongestion.

BACKGROUND: Use of left ventricular assist devices (LVADs) for treatment of advanced heart failure has expanded significantly over the past decade. However, concomitant use of heart failure medical therapies after implant is poorly characterized. METHODS AND RESULTS: We examined the use of heart failure medications before and after LVAD implant in adult patients enrolled in the Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) between 2008 and 2013 (N = 9359). Using logistic regression, we examined relationships between patient characteristics and medication use at 3 months after implant. Baseline rates of heart failure therapies before implant were 38% for angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs), 55% for ß-blockers, 40% for mineralocorticoid receptor antagonists (MRAs), 87% for loop diuretics, 54% for amiodarone, 11% for phosphodiesterase inhibitors, 22% for warfarin, and 54% for antiplatelet agents. By 3 months after implant, the rates were 50% for ACE inhibitors or ARBs, 68% for ß-blockers, 33% for MRAs, 68% for loop diuretics, 42% for amiodarone, 21% for phosphodiesterase inhibitors, 92% for warfarin, and 84% for antiplatelet agents. In general, age, preimplant INTERMACS profile, and prior medication use were associated with medication use at 3 months. CONCLUSIONS: Overall use of neurohormonal antagonists was low after LVAD implant, whereas use of loop diuretics and amiodarone remained high. Heart failure medication use is highly variable, but appears to generally increase after LVAD implantation. Low neurohormonal antagonist use may reflect practice uncertainty in the clinical utility of these medications post-LVAD.

BACKGROUND: Hypoalbuminemia is common in patients with chronic heart failure and, as a marker of disease severity, is associated with an adverse prognosis. Whether hypoalbuminemia contributes to (or is associated with) worse outcomes in acute heart failure (AHF) is unclear. We sought to determine the implications of low serum albumin in patients receiving decongestive therapies for AHF. METHODS AND RESULTS: Baseline serum albumin levels were measured in 456 AHF subjects randomized in the DOSE-AHF and ROSE-AHF trials. We assessed the relationship between admission albumin levels (both as a continuous variable and stratified by median albumin [≥3.5 g/dL]) and worsening renal function (WRF), worsening heart failure (WHF), and clinical decongestion by 72 hours; 7-day cardiorenal biomarkers; and post-discharge outcomes. The mean baseline albumin level was 3.5 ± 0.5 g/dL. Albumin was not associated with WRF, WHF, or clinical decongestion by 72 hours. Furthermore, there was no association between continuous albumin levels and symptom change according to visual analog scale or weight change by 72 hours. Albumin was not associated with 60-day mortality, rehospitalization, or unscheduled emergency room visits. CONCLUSIONS: Baseline serum albumin levels were not associated with short-term clinical outcomes for AHF patients undergoing decongestive therapies. These data suggest that serum albumin may not be a helpful tool to guide decongestion strategies.

BACKGROUND: Patients with advanced heart failure may continue for prolonged times with persistent hemodynamic abnormalities; intermediate- and long-term outcomes of these patients are unknown. METHODS AND RESULTS: We used ESCAPE (Evaluation Study of Congestive Heart Failure and Pulmonary Artery Catheterization Effectiveness) trial data to examine characteristics and outcomes of patients with invasive hemodynamic monitoring during an acute heart failure hospitalization. Patients were stratified by final measurement of cardiac index (CI; L/min/m2) and pulmonary capillary wedge pressure (PCWP; mmHg) before catheter removal. The study groups were CI ≥ 2/PCWP < 20 (n = 74), CI ≥ 2/PCWP ≥ 20 (n = 37), CI < 2/PCWP < 20 (n = 23), and CI < 2/PCWP ≥ 20 (n = 17). Final CI was not associated with the combined risk of death, cardiovascular hospitalization, and transplantation (hazard ratio [HR]1.03, 95% confidence interval 0.96-1.11 per 0.2 L/min/m2 decrease, P = .39), but final PCWP ≥ 20 mmHg was associated with increased risk of these events (HR 2.03, 95% confidence interval 1.31-3.15, P < .01), as was higher final right atrial pressure (HR 1.09, 95% confidence interval 1.06-1.12 per mmHg increase, P < .01). CONCLUSION: Final PCWP and final right atrial pressure were stronger predictors of postdischarge outcomes than CI in patients with advanced heart failure. The ability to lower filling pressures appears to be more prognostically important than improving CI in the management of patients with advanced heart failure.

BACKGROUND: Acute hypothyroidism after brain death results in hemodynamic impairments that limit availability of donor hearts. Thyroid hormone infusions can halt that process and lead to increased utilization of donor organs, but prolonged use of thyroid replacement has not been well studied. METHODS: We developed a 15-question survey regarding policies, procedures, and reporting of thyroid hormone use by organ procurement organizations (OPOs). The survey was posted for 5 weeks on the Association of OPOs Portal. RESULTS: We received 29 responses, representing 24 OPOs. Seventy-two percent reported their OPOs use thyroid hormone for all potential donors and 90% have a protocol for thyroid hormone use. There is a large variation in the maximum dose of thyroid hormone used, and many OPOs have no weaning protocol. Most OPOs do not collect data on total thyroid hormone administered during procurement and would favor more detailed report of thyroid hormone use. CONCLUSIONS: Thyroid hormone use can have important implications for organ selection and cardiac function before and after transplantation. Protocols vary widely with respect to why and how to use and wean thyroid hormone. We believe there should be more detailed reporting of thyroid hormone use for future studies to ensure appropriate donor management.
