Therapy guided by pulmonary artery (PA) pressure monitoring reduces PA pressures and heart failure hospitalizations (HFH) during the first year, but the durability of efficacy and safety through 2 years is not known.The CardioMEMS Post-Approval Study investigated whether benefit and safety were generalized and sustained. Enrollment at 104 centers in the United States included 1200 patients with NYHA Class III symptoms on recommended HF therapies with prior HFH. Therapy was adjusted toward PA diastolic pressure 8-20 mmHg. Intervention frequency and PA pressure reduction were most intense during first 90 days, with sustained reduction of PA diastolic pressure from baseline 24.7 mmHg to 21.0 at 1 year and 20.8 at 2 years for all patients. Patients completing two year follow-up (n = 710) showed similar 2-year reduction (23.9 to 20.8 mmHg), with reduction in PA mean pressure (33.7 to 29.4 mmHg) in patients with reduced left ventricular ejection. The HFH rate was 1.25 events/patient/year prior to sensor implant, 0.54 at 1 year, and 0.37 at 2 years, with 59% of patients free of HFH during follow-up.Reduction in PA pressures and hospitalizations were early and sustained during 2 years of PA pressure-guided management, with no signal of safety concerns regarding the implanted sensor.

Emergency department (ED) providers play a critical role in the stabilization and diagnostic evaluation of patients presenting with acute heart failure (AHF), and EDs are key areas for establishing current best practices and future considerations for the disposition of and decision making for patients with AHF. These elements include accurate risk assessment; response to initial treatment and shared decision making concerning optimal venue of care; reframing of physicians' risk perceptions for patients presenting with AHF; exploration of alternative venues of care beyond hospitalization; population-level changes in demographics, management and outcomes of HF patients; development and testing of data-driven pathways to assist with disposition decisions in the ED; and suggested outcomes for measuring success.

There is increasing evidence regarding the prevalence of genetic cardiomyopathies, for which arrhythmias may be the first presentation. Ventricular and atrial arrhythmias presenting in the absence of known myocardial disease are often labelled as idiopathic, or lone. While ventricular arrhythmias are well-recognized as presentation for arrhythmogenic cardiomyopathy in the right ventricle, the scope of arrhythmogenic cardiomyopathy has broadened to include those with dominant left ventricular involvement, usually with a phenotype of dilated cardiomyopathy. In addition, careful evaluation for genetic cardiomyopathy is also warranted for patients presenting with frequent premature ventricular contractions, conduction system disease, and early onset atrial fibrillation, in which most detected genes are in the cardiomyopathy panels. Sudden death can occur early in the course of these genetic cardiomyopathies, for which risk is not adequately tracked by left ventricular ejection fraction. Only a few of the cardiomyopathy genotypes implicated in early sudden death are recognized in current indications for implantable cardioverter defibrillators which otherwise rely upon a left ventricular ejection fraction ≤0.35 in dilated cardiomyopathy. The genetic diagnoses impact other aspects of clinical management such as exercise prescription and pharmacological therapy of arrhythmias, and new therapies are coming into clinical investigation for specific genetic cardiomyopathies. The expansion of available genetic information and implications raises new challenges for genetic counseling, particularly with the family member who has no evidence of a cardiomyopathy phenotype and may face a potentially negative impact of a genetic diagnosis. Discussions of risk for both probands and relatives need to be tailored to their numeric literacy during shared decision-making. For patients presenting with arrhythmias or cardiomyopathy, extension of genetic testing and its implications will enable cascade screening, intervention to change the trajectory for specific genotype-phenotype profiles, and enable further development and evaluation of emerging targeted therapies.

Introduction Patients with ambulatory advanced heart failure (HF) are increasingly considered for durable mechanical circulatory support (MCS) and heart transplantation and their effective triage requires careful assessment of the clinical trajectory. Methods REVIVAL, a prospective, observational study, enrolled 400 ambulatory advanced HF patients from 21 MCS/transplant centers in 2015-2016. Study design included a clinical re-assessment of Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) profile within 120 days after enrollment. The prognostic impact of a worsening INTERMACS Profile assigned by the treating physician was assessed at 1 year after the Early Relook. Results Early Relook was done in 325 of 400 patients (81%), of whom 24% had a worsened INTERMACS Profile, associated with longer HF history and worse baseline INTERMACS profile, but no difference in baseline LVEF (median 0.20), 6-minute walk, quality of life, or other baseline parameters. Early worsening predicted higher rate of the combined primary endpoint of death, urgent MCS, or urgent transplant by 1 year after Early Relook, (28% vs 15%), with hazard ratio 2.2 (95% CI 1.2- 3.8; p = .006) even after adjusting for baseline INTERMACS Profile and Seattle HF Model score. Deterioration to urgent MCS occurred in 14% vs 5% (p = .006) during the year after Early Relook. Conclusions Early Relook identifies worsening of INTERMACS Profile in a significant population of ambulatory advanced HF, who had worse outcomes over the subsequent year. Early reassessment of ambulatory advanced HF patients should be performed to better define the trajectory of illness and inform triage to advanced therapies.

BACKGROUND: B-type natriuretic peptide (BNP) immunoassays (ia) do not differentiate active and inactive forms. Inactive NT-proBNP is used to track heart failure (HF) during treatment with sacubitril/valsartan, which inhibits BNP degradation. Mass spectrometry (MS) may better assess effects of HF treatment on biologically active BNP1–32. METHODS AND RESULTS: We developed a MS assay with immediate protease inhibition to quantify BNP1–32 over a linear range, using labeled recombinant BNP standard. In four healthy volunteers, BNP1–32 by MS (BNP(MS)) rose from below the 5 pg/ml detection limit to 228 pg/mL after nesiritide. In patients with HF, BNP(MS) was measured in parallel with BNP and NT-proBNP immunoassays before and during sacubitril/valsartan treatment. BNP(MS) was 4.4-fold lower than BNP(ia) in patients with HF. Among patients not taking sacubitril/valsartan and without ESRD, BNP(MS) correlated with BNP(ia) (r(s)=0.77, p

Background Given the shortage of suitable donor hearts for cardiac transplantation and the growing interest in donation after circulatory death (DCD), our institution recently began procuring cardiac allografts from DCD donors. Methods Between October 2020 and March 2021, 15 patients with heart failure underwent cardiac transplantation using DCD allografts. Allografts were procured using a modified extracorporeal membrane oxygenation circuit for thoracic normothermic regional perfusion (TA-NRP) and were subsequently transported using cold static storage. Data collection and analysis were performed with institutional review board approval. Results The mean age of the DCD donors was 23 ± 7 years and average time on TA-NRP was 56 ± 8 minutes. Total ischemic time was 183 ± 31 minutes and distance from transplant center was 373 ± 203 nautical miles. Recipient age was 55 ± 14 years, with 8 (55.3%) recipients on durable left ventricular assist device support. Post-transplant, 6 (40%) recipients experienced mild left ventricle primary graft dysfunction (PGD-LV), 3 (20%) recipients experienced moderate PGD-LV, and no recipients experienced severe PGD-LV. Postoperative transthoracic echocardiogram demonstrated left ventricular ejection fraction >55% in all recipients. One recipient (6.6%) developed International Society for Heart and Lung Transplantation 2R acute cellular rejection on first biopsy. At last follow-up, all 15 recipients were alive past 30-days. Conclusions Cardiac DCD provides an opportunity to increase the availability of donor hearts for transplantation. Utilizing TA-NRP with cold static storage, we have extended the cold ischemic time of DCD allografts to almost 3 hours, allowing for inter-hospital organ transport.

Background On October 18, 2018, several changes to the donor heart allocation system were enacted. We hypothesize that patients undergoing orthotopic heart transplantation (OHT) under the new allocation system will see an increase in ischemic times, rates of primary graft dysfunction, and 1-year mortality due to these changes. Methods In this single-center retrospective study, we reviewed the charts of all OHT patients from October 2017 through October 2019. Pre- and postallocation recipient demographics were compared. Survival analysis was performed using the Kaplan-Meier method. Results A total of 184 patients underwent OHT. Recipient demographics were similar between cohorts. The average distance from donor increased by more than 150 km (p = .006). Patients in the postallocation change cohort demonstrated a significant increase in the rate of severe left ventricle primary graft dysfunction from 5.4% to 18.7% (p = .005). There were no statistically significant differences in 30-day mortality or 1-year survival. Time on the waitlist was reduced from 203.8 to 103.7 days (p = .006). Conclusions Changes in heart allocation resulted in shorter waitlist times at the expense of longer donor distances and ischemic times, with an associated negative impact on early post-transplantation outcomes. No significant differences in 30-day or 1-year mortality were observed.

Objective To describe the intent and early outcomes of elective inotrope use during heart failure hospitalization. Patients and Methods A prospective multisite design was used to collect data for hemodynamically stable patients started electively on inotrope therapy between January 1 and August 31, 2018. We prospectively recorded data when intravenous inotropic therapy was initiated, including survey of the attending cardiologists regarding expectations for the clinical course. Patients were followed up for events through hospital discharge and an additional survey was administered at the end of hospitalization. Results For the 92 patients enrolled, average age was 60 years and ejection fraction was 24%±12%. At the time of inotrope initiation, attending heart failure cardiologists predicted that 50% (n=46) of the patients had a “high or very high” likelihood of becoming dependent on intravenous inotropic therapy and 58% (n=53) had a “high” likelihood of death, transplant, or durable ventricular assist device placement within the next 6 months. Provider predictions regarding death/hospice or need for continued home infusions were accurate only 51% (47 of 92) of the time. Only half the patients (n=47) had goals-of-care conversations before inotrope treatment initiation. Conclusion More than half the patients (51 of 92) electively started on inotrope treatment without present or imminent cardiogenic shock ultimately required home inotrope therapy, died during admission, or were discharged with hospice. Heart failure clinicians could not reliably identify those patients at the time of inotrope therapy initiation and goals-of-care discussions were not frequently performed.

The interrelationships between atrial fibrillation (AF) and heart failure (HF) are complex and poorly understood, yet the number of patients with AF and HF continues to increase worldwide. Thus, there is a need for initiatives that prioritize research on the intersection between AF and HF. This article summarizes the proceedings of a virtual workshop convened by the US National Heart, Lung, and Blood Institute to identify important research opportunities in AF and HF. Key knowledge gaps were reviewed and research priorities were proposed for characterizing the pathophysiological overlap and deleterious interactions between AF and HF; preventing HF in people with AF; preventing AF in individuals with HF; and addressing symptom burden and health status outcomes in AF and HF. These research priorities will hopefully help inform, encourage, and stimulate innovative, cost-efficient, and transformative studies to enhance the outcomes of patients with AF and HF.

Heart failure (HF) patients experience a high burden of symptoms and functional limitations, and morbidity and mortality remain high despite successful therapies. The majority of HF drugs in the United States are approved for reducing hospitalization and mortality, while only a few have indications for improving quality of life, physical function, or symptoms. Patient-reported outcomes that directly measure patient's perception of health status (symptoms, physical function, or quality of life) are potentially approvable endpoints in drug development. This paper summarizes the history of endpoints used for HF drug approvals in the United States and reviews endpoints that measure symptoms, physical function, or quality of life in HF patients.

Whereas multiple national, international, and trial registries for heart failure have been created, international standards for clinical assessment and outcome measurement do not currently exist. The working group’s objective was to facilitate international comparison in heart failure care, using standardized parameters and meaningful patient-centered outcomes for research and quality of care assessments. The International Consortium for Health Outcomes Measurement recruited an international working group of clinical heart failure experts, researchers, and patient representatives to define a standard set of outcomes and risk-adjustment variables. This was designed to document, compare, and ultimately improve patient care outcomes in the heart failure population, with a focus on global feasibility and relevance. The working group employed a Delphi process, patient focus groups, online patient surveys, and multiple systematic publications searches. The process occurred over 10 months, employing 7 international teleconferences. A 17-item set has been established, addressing selected functional, psychosocial, burden of care, and survival outcome domains. These measures were designed to include all patients with heart failure, whether entered at first presentation or subsequent decompensation, excluding cardiogenic shock. Sources include clinician report, administrative data, and validated patient-reported outcome measurement tools: the Kansas City Cardiomyopathy Questionnaire; the Patient Health Questionnaire-2; and the Patient-Reported Outcomes Measurement Information System. Recommended data included those to support risk adjustment and benchmarking across providers and regions. The International Consortium for Health Outcomes Measurement developed a dataset designed to capture, compare, and improve care for heart failure, with feasibility and relevance for patients and clinicians worldwide., Central Illustration, Highlights • ICHOM seeks to help standardize and align outcome measurement efforts globally. • Standardization and alignment of this sort does not exist for heart failure. • The heart failure working group developed a standard set of 17 outcomes to be measured. • ICHOM hopes this standardization effort will increase quality and value in heart failure care.

Importance Early-onset atrial fibrillation (AF) can be the initial manifestation of a more serious underlying inherited cardiomyopathy or arrhythmia syndrome. Objective To examine the results of genetic testing for early-onset AF. Design, Setting, and Participants This prospective, observational cohort study enrolled participants from an academic medical center who had AF diagnosed before 66 years of age and underwent whole genome sequencing through the National Heart, Lung, and Blood Institute’s Trans-Omics for Precision Medicine program. Participants were enrolled from November 23, 1999, to June 2, 2015. Data analysis was performed from October 24, 2020, to March 11, 2021. Exposures Rare variants identified in a panel of 145 genes that are included on cardiomyopathy and arrhythmia panels used by commercial clinical genetic testing laboratories. Main Outcomes and Measures Sequencing data were analyzed using an automated process followed by manual review by a panel of independent, blinded reviewers. The primary outcome was classification of rare variants using American College of Medical Genetics and Genomics criteria: benign, likely benign, variant of undetermined significance, likely pathogenic, or pathogenic. Disease-associated variants were defined as pathogenic/likely pathogenic variants in genes associated with autosomal dominant or X-linked dominant disorders. Results Among 1293 participants (934 [72.2%] male; median [interquartile range] age at enrollment, 56 [48-61] years; median [interquartile range] age at AF diagnosis, 50 [41-56] years), genetic testing identified 131 participants (10.1%) with a disease-associated variant, 812 (62.8%) with a variant of undetermined significance, 92 (7.1%) as heterozygous carriers for an autosomal recessive disorder, and 258 (20.0%) with no suspicious variant. The likelihood of a disease-associated variant was highest in participants with AF diagnosed before the age of 30 years (20 of 119 [16.8%; 95% CI, 10.0%-23.6%]) and lowest after the age of 60 years (8 of 112 [7.1%; 95% CI, 2.4%-11.9%]). Disease-associated variants were more often associated with inherited cardiomyopathy syndromes compared with inherited arrhythmias. The most common genes wereTTN(n = 38),MYH7(n = 18),MYH6(n = 10),LMNA(n = 9), andKCNQ1(n = 8). Conclusions and Relevance In this cohort study, genetic testing identified a disease-associated variant in 10% of patients with early-onset AF (the percentage was higher if diagnosed before the age of 30 years and lower if diagnosed after the age of 60 years). Most pathogenic/likely pathogenic variants are in genes associated with cardiomyopathy. These results support the use of genetic testing in early-onset AF.

Background In patients hospitalized with acute heart failure (AHF), low urine sodium concentration (U Na) after diuretic treatment may identify patients at risk for longer length of stay (LOS) and adverse events. We investigated the prognostic significance of 24‐hour cumulative postdiuretic urine sodium concentration in a multicenter clinical trial population. Methods The Renal Optimization Strategies Evaluation AHF (ROSE AHF) trial randomized 360 patients with AHF and renal dysfunction receiving intravenous diuretic to dopamine, nesiritide, or placebo. Sodium concentration was measured in cumulative urine sample collected during the first 24 hours after randomization in 298 patients. Based on prior studies, lower U Na was defined as ≤60 mmol/L. Results Lower U Na was present in 142 (48%) patients, who had longer LOS (7 days vs 5 days, P

OBJECTIVE: To determine if a clinician-centered teaching intervention and automatic reminders increased ICD deactivation discussions and increased device deactivation. BACKGROUND: Although implantable cardioverter-defibrillators (ICDs) reduce sudden death, these patients die of heart failure (HF) or other diseases. To prevent shocks at the end of life, clinicians should discuss deactivating the defibrillation function. METHODS: We conducted a 6-center, single-blinded, cluster-randomized, controlled trial. Primary outcomes were proportion of patients: 1) having ICD deactivation discussions and 2) having the shocking function deactivated. Secondary outcomes included goals of care conversations and advance directive completion. RESULTS: We report on 525 subjects with advanced HF who had an ICD – 301 intervention and 224 control. At baseline 52% (272) were not candidates for advanced therapies (i.e. cardiac transplant or mechanical circulatory support). There were no differences in discussions (41 (14%) vs. 26 (12%)) or deactivation (33 (11%) vs. 26 (12%)). In pre-specified subgroup analyses of patients not candidates for advanced therapies, the intervention increased deactivation discussions (32 (25%) vs. 16 (11%); OR 2.90, P = 0.003). Overall 99 patients died; there were no differences in conversations or deactivations amongst decedents. Secondary Outcomes: Among all participants there was an increase in goals of care conversations (47% intervention vs. 38% control, OR 1.53, P = 0.04). There were no differences in completion of advance directives. CONCLUSIONS: Our intervention increased conversations about ICD deactivation and goals of care. HF clinicians were able to apply new communication techniques based on patients’ severity of illness. CLINICAL TRIALS REGISTRATION: ClinicalTrials.gov

Background Patient limitations guide selection of heart failure therapies, for which indications often specify New York Heart Association Class. Objectives To determine the extent of patient‐reported limitations during daily activities and compare to New York Heart Association class assigned by providers during the same visit, and to left ventricular ejection fraction (LVEF) group. Methods and Results While waiting for their appointment, 948 patients on return visits to an ambulatory HF clinic completed a written questionnaire assessing specific activity limitations, which were compared to physician‐assigned NYHA class during the same visit. Patient‐reported limitation to perform daily activity ranged from 25% for bathing to 61% for yardwork or housework and 71% for jogging or hurrying. Most patients who did not report limitations to perform daily life activities were correctly classified as NYHA I by the physicians (76%), but 12% of the 376 patients classified as NYHA I reported limitations to showering or bathing and 73% reported limitations while doing yardwork or house work. Limitation to walking was reported by 172 patients (50%) classified as class II. Limitations to walking one block were most common in patients with LVEF ≥40% compared to patients with LVEF

Objectives This study sought to explore clinical characteristics and outcomes in women and men with ambulatory advanced heart failure (HF). Background Women have been underrepresented in studies of advanced HF and have an increased mortality on the transplant waiting list and early after mechanical circulatory support (MCS). An increased understanding of the differential burden of HF between women and men is required to inform the use of mechanical circulatory support in ambulatory advanced HF patients. Methods REVIVAL (Registry Evaluation for Vital Information on Ventricular Assist Devices in Ambulatory Life) is a prospective, observational study of 400 outpatients with chronic systolic HF, New York Heart Association functional class II to IV, and 1 additional high-risk feature. Clinical characteristics, quality of life, and functional capacity were compared between women and men, as was a primary composite endpoint of death, durable MCS, or urgent heart transplantation at 1 year. Results REVIVAL enrolled 99 women (25% of the cohort) who had similar age, ejection fraction, INTERMACS (Interagency Registry for Mechanically Assisted Circulatory Support) profiles, medication use, and willingness to consider MCS as the men enrolled; however, women reported significantly greater limitations in quality of life with respect to physical limitation, reduced 6-min walk distance, and more frequent symptoms of depression. Nevertheless, 1-year combined risk of death, durable MCS, or urgent transplantation did not differ between women and men (24% vs. 22%; p = 0.94). Conclusions This study represents the largest report to date of women with ambulatory advanced HF receiving contemporary therapies. Systematic elicitation of patient-reported outcome measures uncovered an added burden of HF in women and may be an appropriate target of augmented support and intervention.

Objectives: This study aimed to evaluate the incidence and causes of hospitalization in the year preceding death of patients with heart failure (HF). Background: Hospitalizations in HF are common, especially in the last period of the lives of patients with HF, but little is known about hospitalization burden and causes during this phase of the disease. Methods: From Danish nationwide registries, we identified patients who died in the period 2001–2016 after having experienced HF for at least 1 year, and examined hospitalizations during the last year of life in age- and sex-stratified analyses. Results: We included 32,157 patients. Median age at time of death was 81 years; 39% were women. A total of 26,561 (84%) patients were hospitalized at least once during the last year of life. The patients experienced a median of 2 (1 to 3) hospitalizations and spent 14 (3 to 31) days in the hospital. Of all hospitalizations (n = 80,362), 9,644 (12%) were due to HF, 14,738 (18%) due to other cardiovascular (CV) causes, and 51,696 (64%) due to non-CV causes (p < 0.001). The frequency of hospitalizations increased toward death, but the domination of non-CV causes remained consistent throughout the year, regardless of age and sex. If we included diagnoses covering renal insufficiency in the definition of HF hospitalizations, non-CV hospitalizations remained dominant (58%). Conclusions: During the last year alive, patients with HF were more often hospitalized due to non-CV causes rather than HF. These findings warrant more focus on a multidisciplinary approach toward end-of-life care in patients with HF.

Background The pulmonary artery catheter (PAC) has been used in a wide range of critically ill patients. It is not indicated for routine care of heart failure (HF), but its role in cardiogenic shock (CS) has not been clarified. Methods and Results We conducted a retrospective cohort study with the use of the National Inpatient Sample and identified a total of 9,431,944 adult patients admitted from 2004 to 2014 with the primary diagnosis of HF (n = 8,516,528) or who developed CS (n = 915,416) during the index hospitalization. Overall, patients with PAC had increased hospital costs, length of stay, and mechanical circulatory support use. In patients with HF, PAC use was associated with higher mortality (9.9% vs 3.3%, OR 3.96; P < .001) but the excess of mortality declined over time. In those with CS, PAC was associated with lower mortality (35.1% vs 39.2%, OR 0.91; P < .001) and in-hospital cardiac arrest (14.9% vs 18.3%, OR 0.77; P < .001); this paradox persisted after propensity score matching. Conclusions The use of PAC in CS has decreased from 2004 to 2014, although its use is now associated with improved outcomes, which may reflect better selection of patients or better use of the information to guide therapies. Our data provide reassurance that PAC use in this population is an appropriate strategy.

BACKGROUND The outlook for ambulatory patients with advanced heart failure (HF) and the appropriate timing for left ventricular assist device (LVAD) or transplant remain uncertain. The aim of this study was to better understand disease trajectory and rates of progression to subsequent LVAD therapy and transplant in ambulatory advanced HF. METHODS See Related Editorial, page XXX Patients with advanced HF who were New York Heart Association (NYHA) Class III or IV and Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) Profiles 4 to 7, despite optimal medical therapy (without inotropic therapy), were enrolled across 11 centers and followed for the end-points of survival, transplantation , LVAD placement, and health-related quality of life. A secondary intention-to-treat survival analysis compared outcomes for MedaMACS patients with a matched group of Profile 4 to 7 patients with LVADs from the INTERMACS registry. RESULTS Between May 2013 and October 2015, 161 patients were enrolled with INTERMACS Profiles 4 (12%), 5 (32%), 6 (49%), and 7 (7%). By 2 years after enrollment, 75 (47%) patients had reached a primary end-point with 39 (24%) deaths, 17 (11%) undergoing LVAD implantation, and 19 (12%) receiving a transplant. Compared with 1,753 patients with Profiles 4 to 7 receiving LVAD therapy, there was no overall difference in intention-to-treat survival between medical and LVAD therapy, but survival with LVAD therapy was superior to medical therapy among Profile 4 and 5 patients (p = 0.0092). Baseline health-related quality of life was lower among patients receiving a LVAD than those enrolled on continuing oral medical therapy, but increased after 1 year for survivors in both cohorts. CONCLUSIONS Ambulatory patients with advanced HF are at high risk for poor outcomes, with only 53% alive on medical therapy after 2 years of follow-up. Survival was similar for medical and LVAD therapy in the overall cohort, which included the lower severity Profiles 6 and 7, but survival was better with LVAD therapy among patients in Profiles 4 and 5. Given the poor outcomes in this group of advanced HF patients, timely consideration of transplant and LVAD is of critical importance.

Despite all available therapies, the rates of hospitalization and death from heart failure (HF) remain unacceptably high. The most common reasons for hospital admission are symptoms related to congestion. During hospitalization, most patients respond well to standard therapy and are discharged with significantly improved symptoms. Post-discharge, many patients receive diligent and frequent follow-up. However, rehospitalization rates remain high. One potential explanation is a persistent failure by clinicians to adequately manage congestion in the outpatient setting. The failure to successfully manage these patients post-discharge may represent an unmet need to improve the way congestion is both recognized and treated. A primary aim of future HF management may be to improve clinical surveillance to prevent and manage chronic fluid overload while simultaneously maximizing the use of evidence-based therapies with proven long-term benefit. Improvement in cardiac function is the ultimate goal and maintenance of a “dry” clinical profile is important to prevent hospital admission and improve prognosis. This paper focuses on methods for monitoring congestion, and strategies for water and sodium management in the context of the complex interplay between the cardiac and renal systems. A rationale for improving recognition and treatment of congestion is also proposed.

Background Patients with recurring heart failure (HF) following cardiac resynchronization therapy fare poorly. Their management is undecided. We tested remote hemodynamic‐guided pharmacotherapy. Methods and Results We evaluated cardiac resynchronization therapy subjects included in the CHAMPION (CardioMEMS Heart Sensor Allows Monitoring of Pressure to Improve Outcomes in New York Heart Association Class III Heart Failure Patients) trial, which randomized patients with persistent New York Heart Association Class III symptoms and ≥1 HF hospitalization in the previous 12 months to remotely managed pulmonary artery (PA) pressure‐guided management (treatment) or usual HF care (control). Diuretics and/or vasodilators were adjusted conventionally in control and included remote PA pressure information in treatment. Annualized HF hospitalization rates, changes in PA pressures over time (analyzed by area under the curve), changes in medications, and quality of life (Minnesota Living with Heart Failure Questionnaire scores) were assessed. Patients who had cardiac resynchronization therapy (n=190, median implant duration 755 days) at enrollment had poor hemodynamic function (cardiac index 2.00±0.59 L/min per m 2 ), high comorbidity burden (67% had secondary pulmonary hypertension, 61% had estimated glomerular filtration rate 2 ), and poor Minnesota Living with Heart Failure Questionnaire scores (57±24). During 18 months randomized follow‐up, HF hospitalizations were 30% lower in treatment (n=91, 62 events, 0.46 events/patient‐year) versus control patients (n=99, 93 events, 0.68 events/patient‐year) (hazard ratio, 0.70; 95% CI, 0.51–0.96; P =0.028). Treatment patients had more medication up‐/down‐titrations (847 versus 346 in control, P P =0.002), and quality of life improvement (Minnesota Living with Heart Failure Questionnaire decreased −13.5±23 versus −4.9±24.8 in control, P =0.006). Conclusions Remote hemodynamic‐guided adjustment of medical therapies decreased PA pressures and the burden of HF symptoms and hospitalizations in patients with recurring Class III HF and hospitalizations, beyond the effect of cardiac resynchronization therapy.

Objectives This study sought to determine the impact of therapy guided by pulmonary artery (PA) pressure monitoring in patients with heart failure (HF) and obesity. Background Obesity is prevalent in HF and associated with volume retention, but it complicates clinical assessment of congestion. Methods The CardioMEMS Post Approval Study was a prospective, multicenter, open-label trial in 1,200 patients with New York Heart Association functional class III HF and prior HF hospitalization (HFH) within 12 months. Patients with a body mass index (BMI) >35 kg/m2 were required to have a chest circumference Results Baseline PA diastolic pressure was higher in patients with BMI ≥35 kg/m2 regardless of EF, but all PA pressures were reduced at 12 months in each cohort (P 50% in both cohorts for EF Conclusions Management guided by PA pressure monitoring effectively reduced pressures, HFH, and all-cause hospitalization in patients with obesity regardless of EF.

Introduction: Effective management of ambulatory heart failure (HF) requires active patient (pt) participation. In telemonitoring of weights and symptoms, pt adherence to transmission is often halved within 6 months (M). Although ambulatory pulmonary pressure-guided management decreases hospitalizations and improves quality of life, the time course of pt perception of illness and sense of security in relation to monitoring frequency is not known. Hypothesis: Pts will perceive decreased impact of their HF during pulmonary pressure-guided management, which may contribute to their engagement in transmission of ambulatory PAP. Methods: The post-approval study for the implanted PA sensor was amended to include serial measurements of pt reported outcomes, (PRO, n=143), including the Brief Illness Perception Questionnaire (BIPQ). Treatment was adjusted to a target PA diastolic pressure 8 to 20 mmHg and adherence to transmitting pressure data from home was collected. Results: In the PRO cohort, mean age was 68 years, 58% were male, and 55% with HFpEF. Negative illness perception (BIPQ) decreased during each measurement interval. Pts reported improvement in symptoms, sense of security, sense of control and less impact of illness on their emotions at each time point, equally with HFpEF or HFrEF. In this cohort pt adherence to transmitting pressures was high throughout 24 M, Fig.1. Perception of illness was most favorable at 2 years, at which time there was a slight decline in transmission frequency. Conclusions: Pt perception of HF was positively impacted during ambulatory hemodynamic monitoring including improvement in symptoms, less emotional effect of illness, improved sense of security and control over their HF throughout follow-up. This was associated with high-level pt adherence to pressure data transmission. The optimal level of chronic monitoring for stable pts to maintain clinical benefit while minimizing disease awareness beyond 2 years is still unknown.

Background: Ambulatory hemodynamic monitoring with an implantable pulmonary artery (PA) sensor is approved for patients with New York Heart Association Class III heart failure (HF) and a prior HF hospitalization (HFH) within 12 months. The objective of this study was to assess the efficacy and safety of PA pressure-guided therapy in routine clinical practice with special focus on subgroups defined by sex, race, and ejection fraction. Methods: This multi-center, prospective, open-label, observational, single-arm trial of 1200 patients across 104 centers within the United States with New York Heart Association class III HF and a prior HFH within 12 months evaluated patients undergoing PA pressure sensor implantation between September 1, 2014, and October 11, 2017. The primary efficacy outcome was the difference between rates of adjudicated HFH 1 year after compared with the 1 year before sensor implantation. Safety end points were freedom from device- or system-related complications at 2 years and freedom from pressure sensor failure at 2 years. Results: Mean age for the population was 69 years, 37.7% were women, 17.2% were non-White, and 46.8% had preserved ejection fraction. During the year after sensor implantation, the mean rate of daily pressure transmission was 76±24% and PA pressures declined significantly. The rate of HFH was significantly lower at 1 year compared with the year before implantation (0.54 versus 1.25 events/patient-years, hazard ratio 0.43 [95% CI, 0.39–0.47], P P Conclusions: In routine clinical practice as in clinical trials, PA pressure-guided therapy for HF was associated with lower PA pressures, lower rates of HFH and all-cause hospitalization, and low rates of adverse events across a broad range of patients with symptomatic HF and prior HFH.

Background Mortality is increased following a hospitalization for decompensated heart failure ( HF ), during which diuretics are usually intensified. It is unclear how risk is affected after outpatient intensification of diuretic therapy for HF . Methods and Results From nationwide administrative registers, we identified all Danish patients who were diagnosed with HF from 2001 to 2016 and received angiotensin‐converting enzyme inhibitor/angiotensin receptor blocker and β blocker within 120 days. Subsequent follow‐up tracked progressive events of diuretic intensification and HF hospitalization. Intensification events were defined as new addition or doubling of loop diuretic or addition of thiazide to loop diuretic. These events were included in multivariable Cox regression models, calculating 1‐year mortality hazard after each year since inclusion. Patients with an intensification event or hospitalization were risk set matched to 2 nonworsened HF controls and absolute 1‐year mortality risks were calculated using Kaplan‐Meier estimates. We included 74 990 patients, their median age was 71 years, and 36% were women. Intensification events were associated with significantly increased mortality at all times during follow‐up. One‐year mortality was 18.0% after an intensification event, 22.6% after HF hospitalization, and 10.4% for matched controls with neither. In a multivariable Cox model adjusted for age, sex, ischemic heart disease, atrial fibrillation, chronic obstructive pulmonary disease, and diabetes mellitus, the hazard ratio for 1‐year death after an intensification event was 1.75 (95% CI , 1.66–1.85), and it was 2.28 (95% CI , 2.16–2.41) after HF hospitalization. Conclusions In a nationwide cohort of patients with HF , outpatient intensification events were associated with almost 2‐fold risk of mortality during the next year. Although HF hospitalization was associated with a higher risk, the need to intensify diuretics in the outpatient setting is a signal to review and intensify efforts to improve HF outcomes.

BACKGROUND: Heart failure (HF) is a major source of morbidity and mortality. Fluid retention and shortness of breath are its cardinal manifestations for which loop diuretics are used. Although their usefulness is well accepted, less is known about their role in improving clinical outcomes. OBJECTIVES: To determine the relationship between loop diuretics and clinical outcomes in patients with HF. METHODS: Of the 25,345 older patients hospitalized for HF in Medicare-linked OPTIMIZE-HF registry, 9,866 (39%) received no pre-admission diuretics. We excluded 1,083 patients receiving dialysis and 847 discharged on thiazide diuretics. Of the remaining 7,936 patients, 5,568 (70%) were prescribed loop diuretics at discharge. Using propensity scores for receipt of loop diuretics estimated for each of the 7,936 patients, we assembled a matched cohort of 2,191 pairs of patients, balanced on 74 baseline characteristics. Hazard ratios (HRs) and 95% confidence intervals (CIs) for outcomes were estimated in the matched cohort. RESULTS: Matched patients (N=4,382) had a mean age of 78 years, 54% were women, and 11% African American. 30-day all-cause mortality occurred in 4.9% (107/2,191) and 6.6% (144/2,191) of patients in the loop diuretic and no loop diuretic groups, respectively (HR when the use of loop diuretics was compared to their nonuse, 0.73; 95% CI, 0.57–0.94; p=0.016). Patients in the loop diuretic group had a significantly lower risk of 30-day HF readmission (HR, 0.79; 95% CI, 0.63–0.99; p=0.037) but not of 30-day all-cause readmission (HR, 0.89; 95% CI, 0.79–1.01; p=0.081). None of the associations was statistically significant during 60 days of follow-up. CONCLUSION: Hospitalized older patients not taking diuretics prior to hospitalization for HF decompensation who received a discharge prescription for loop diuretics had significantly better 30-day clinical outcomes than those not discharged on loop diuretics. These findings provide new information about short-term clinical benefits associated with loop diuretic use in HF.

BACKGROUND: Heart failure (HF) with preserved ejection fraction (HFpEF) is a heterogeneous syndrome. Some patients develop elevated filling pressures exclusively during exercise and never require hospitalization, whereas others periodically develop congestion that requires inpatient treatment. The features differentiating these cohorts are unclear. METHODS: We performed a secondary analysis of 7 NIH sponsored multicenter trials of HFpEF (EF≥50%, n=727). Patients were stratified by history of HF hospitalization, comparing patients never hospitalized (HFpEF(NH)) to those with a prior hospitalization (HFpEF(PH)). Currently hospitalized (HFpEF(CH)) patients were included to fill the spectrum. Clinical characteristics, cardiac structure, biomarkers, quality of life (QOL), functional capacity, activity levels, and outcomes were compared. RESULTS: As expected, HFpEF(CH) (n=338) displayed the greatest severity of congestion, as assessed by NTproBNP levels, edema, and orthopnea. As compared to HFpEF(NH) (n=109), HFpEF(PH) (n=280) displayed greater comorbidity burden with more lung disease, renal dysfunction and anemia, along with lower activity levels (accelerometry), poorer exercise capacity (6 minute walk distance and peak exercise capacity), and more orthopnea. Patients with current or prior hospitalization displayed higher rates of future HF hospitalization, but QOL was similarly impaired in all HFpEF patients, regardless of hospitalization history. CONCLUSIONS: A greater burden of non-cardiac organ dysfunction, sedentariness, functional impairment, and higher event rates distinguish patients with HFpEF and prior HF hospitalization from those never hospitalized. Despite lower event rates, quality of life is severely and similarly in patients with no history of hospitalization. These data suggest that the two clinical profiles of HFpEF may require different treatment strategies.

Background: Patients with heart failure (HF) often have multiple chronic conditions that may impact health-related quality of life (HRQOL) despite HF therapy. We sought to determine the association between noncardiac comorbidities and HRQOL in ambulatory patients with advanced HF. Methods: Baseline data from 373 subjects in REVIVAL (Registry Evaluation of Vital Information for Ventricular Assist Devices in Ambulatory Life) were analyzed using multivariable general linear models to evaluate the relationship between comorbidities and HRQOL (EuroQol Visual Analogue Scale, EQ-5D-3L Index Score, and Kansas City Cardiomyopathy Questionnaire). The primary independent variables were a comorbidity index (sum of 14 noncardiac conditions), a residual comorbidity index (without depression), and depression alone. The median (25th to 75th percentile) number of comorbidities was 3 (2–4). Results: Increasing comorbidity burden was associated with a reduction in generic (EQ-5D Index, P =0.005) and HF-specific (Kansas City Cardiomyopathy Questionnaire, P =0.001) HRQOL. The residual comorbidity index was not associated with HRQOL when depression included in the model independently, while depression was associated with HRQOL across all measures. Participants with depression (versus without) scored on average 13 points (95% CI, 8–17) lower on the EuroQol Visual Analogue Scale, 0.15 points (95% CI, 0.12–0.18) lower on the EQ-5D Index, and 24.9 points (95% CI, 21.2–28.5) lower on the Kansas City Cardiomyopathy Questionnaire overall summary score. Conclusions: While noncardiac comorbidities were prevalent in ambulatory advanced HF patients, only depression was associated with decreased generic and HF-specific HRQOL. Other than depression, the presence of noncardiac comorbidities should not impact expected gains in HRQOL following ventricular assist device implantation, provided the conditions are not a contraindication to implant.

BACKGROUND: Heart failure (HF) is widely associated with a median survival of 5 years. However, population level data on survival and HF progression has been limited for key subgroups. We assessed survival and HF progression, defined as hospitalization or outpatient diuretic intensification in patients ≤70 years without severe comorbidity, who received relevant medical therapy.METHODS: From administrative registers, we identified all Danish patients ≤70 years diagnosed with HF 2000-2012 without severe comorbidity, survived for 120 days to receive angiotensin converting enzyme inhibitors (ACE-I)/angiotensin receptor blocker (ARB) and beta blocker. Risk of death or progression of HF was assessed with Kaplan-Meier and Aalen Johansen estimators, respectively. Cox regression models were used to identify factors associated with risk of death.RESULTS: We included 19,985 patients, median age 61, 25% women - 1/3 of all HF patients ≤70 years. We excluded 237 patients who died within 120 days and 21,065 due to severe comorbidity. Five-year cumulative incidence of all-cause death was 14% (95%-confidence interval [CI]:13-14). Risk of death was increased for patients first diagnosed in hospital compared to outpatient clinics (hazard ratio: 1.51, 95%-CI:1.38-1.65, p < 0.001). Five-year cumulative incidence of HF hospitalization: 18% (95%-CI, 18-19) and intensification of diuretic therapy: 14% (95%-CI, 14-15).CONCLUSIONS: In patients ≤70 years without severe comorbidity, five-year mortality was only 14% and almost 2/3 were alive after 5 years without evident HF progression. Discussion of prognosis should be tailored to age and health status to provide realistic expectations for patients newly diagnosed and treated with recommended therapies for HF.
