ABSTRACT: Aims
Current evidence about the effect of angiotensin receptor blocker (ARB) on the outcome of heart failure with mid-range ejection fraction (HFmrEF) is lacking. We aim to assess the association between use of ARB and 1 year all-cause mortality after hospitalization for HFmrEF.Methods and results
We analysed the data of patients with ejection fraction of 40-49% in China Patient-centred Evaluative Assessment of Cardiac Events Prospective Heart Failure Study; 4907 patients hospitalized for heart failure from 52 Chinese hospitals were enrolled from August 2016 to May 2018. Use of ARB was determined by prescriptions at discharge. Patients who died during hospitalization or were using angiotensin-converting enzyme inhibitors at discharge were excluded. The association between the use of ARB and outcome was assessed using stabilized inverse probability of treatment weighting-adjusted Kaplan-Meier and Cox regression analyses. A total of 701 patients with HFmrEF were included for analysis. The mean age was 66.4 ± 12.8 years, and 267 (38.1%) were female. Of them, 244 were treated (34.8%) with ARB. During the 1 year follow-up period, patients treated with ARB had lower all-cause mortality compared with untreated patients (11.5% vs. 21.9%, P = 0.0005). Inverse probability of treatment weighting-adjusted Cox regression analysis showed that use of ARB was associated with significantly reduced all-cause mortality (adjusted hazard ratio 0.44, 95% confidence interval 0.28-0.69, P = 0.0004).Conclusions
Among patients hospitalized for HFmrEF, the use of ARB was associated with lower 1 year mortality after discharge.

Project description:AimsThe beneficial effect of β-blocker on heart failure with reduced ejection fraction is well established. However, its effect on the 1-year outcome of heart failure with mid-range ejection fraction (HFmrEF) remains unclear.Methods and resultsWe analysed the data of the patients with left ventricular ejection fraction (LVEF) between 40% and 49% in China Patient-centred Evaluative Assessment of Cardiac Events Prospective Heart Failure Study (China PEACE 5p-HF Study), in which patients hospitalized for heart failure from 52 Chinese hospitals were recruited from 2016 to 2018. Two primary outcomes were all-cause death and all-cause hospitalization. The associations between β-blocker use at discharge and outcomes were assessed by inverse probability of treatment weighting (IPTW)-weighted Cox regression analyses. To assess consistency, IPTW adjusting medications analyses, multivariable analyses and dose-effect analyses were performed. A total of 1035 HFmrEF patients were included in the analysis. The mean age was 65.5 ± 12.7 years and 377 (36.4%) were female. The median (interquartile range) of LVEF was 44% (42-47%). Six hundred and sixty-one (63.8%) were treated with β-blocker. Patients using β-blocker were younger with better cardiac function, and more likely to use renin-angiotensin system inhibitor and mineralocorticoid receptor antagonist. During the 1-year follow-up, death occurred in 84 (12.7%) treated and 85 (22.7%) untreated patients (P < 0.0001); all-cause hospitalization occurred in 298 (45.1%) treated and 188 (50.3%) untreated patients (P = 0.04). After IPTW-weighted adjustment, β-blocker use was significantly associated with lower risk of all-cause death [hazard ratio (HR): 0.70; 95% confidence interval (CI): 0.51-0.96, P = 0.03], but not with lower all-cause hospitalization (HR, 0.92, 95% CI, 0.76-1.10, P = 0.36). Consistency analyses showed consistent favourable effect of β-blocker on all-cause death, but not on all-cause hospitalization.ConclusionsAmong patients with HFmrEF, β-blocker use was associated with lower risk of all-cause death, but not with lower risk of all-cause hospitalization.

Project description:AimsSpironolactone has been shown to improve outcomes in patients with heart failure (HF) with reduced ejection fraction (EF). We investigated whether the discharge use of spironolactone could be associated with better long-term outcomes among patients with HF with mid-range EF (HFmrEF).Methods and resultsWe analysed HFmrEF (left ventricular EF 40-49%) patients enrolled in the Japanese Cardiac Registry of Heart Failure in Cardiology, which prospectively studied the clinical characteristics, treatments, and long-term outcomes of patients hospitalized due to HF. Patients were divided into two groups according to the use of spironolactone at discharge. The primary outcome was a composite of all-cause death or HF rehospitalization. A total of 457 patients had HFmrEF. The mean age was 69.3 years and 286 (62.6%) were male. Among them, spironolactone was prescribed at discharge in 158 patients (34.6%). Chronic kidney disease (7.6% vs. 16.8%, P = 0.007) was less prevalent and loop diuretics (89.2% vs. 70.2%, P < 0.001) were more often prescribed in patients with spironolactone. During a mean follow-up of 2.2 years, patients with spironolactone had a lower incidence rate of the primary outcome than those without it (171.5 vs. 278.8 primary outcome per 1000 patient-years, incidence rate ratio 0.61, 95% confidence interval 0.44-0.86; P = 0.004). After multivariable adjustment, spironolactone use at discharge was associated with a significant reduction in the composite of all-cause death or HF rehospitalization (adjusted hazard ratio 0.63, 95% confidence interval 0.44-0.90, P = 0.010).ConclusionsAmong patients with HF hospitalized for HFmrEF, spironolactone use at discharge was associated with better long-term outcomes.

Project description:AIMS:While heart failure with preserved (HFpEF) and reduced ejection fraction (HFrEF) are well described, determinants and outcomes of heart failure with mid-range ejection fraction (HFmrEF) remain unclear. We sought to examine clinical and biochemical predictors of incident HFmrEF in the community. METHODS AND RESULTS:We pooled data from four community-based longitudinal cohorts, with ascertainment of new heart failure (HF) classified into HFmrEF [ejection fraction (EF) 41-49%], HFpEF (EF ?50%), and HFrEF (EF ?40%). Predictors of incident HF subtypes were assessed using multivariable Cox models. Among 28 820 participants free of HF followed for a median of 12?years, there were 200 new HFmrEF cases, compared with 811 HFpEF and 1048 HFrEF. Clinical predictors of HFmrEF included age, male sex, systolic blood pressure, diabetes mellitus, and prior myocardial infarction (multivariable adjusted P ??0.003 for all). Biomarkers that predicted HFmrEF included natriuretic peptides, cystatin-C, and high-sensitivity troponin (P ??0.0004 for all). Natriuretic peptides were stronger predictors of HFrEF [hazard ratio (HR) 2.00 per 1 standard deviation increase, 95% confidence interval (CI) 1.81-2.20] than of HFmrEF (HR 1.51, 95% CI 1.20-1.90, P =?0.01 for difference), and did not differ in their association with incident HFmrEF and HFpEF (HR 1.56, 95% CI 1.41-1.73, P =?0.68 for difference). All-cause mortality following the onset of HFmrEF was worse than that of HFpEF (50 vs. 39 events per 1000 person-years, P =?0.02), but comparable to that of HFrEF (46 events per 1000 person-years, P =?0.78). CONCLUSIONS:We found overlap in predictors of incident HFmrEF with other HF subtypes. In contrast, mortality risk after HFmrEF was worse than HFpEF, and similar to HFrEF.

Project description:AimsHeart failure patients with mid-range ejection fraction (HFmrEF) have overlapping clinical features, compared with patients with reduced ejection fraction (HFrEF) and preserved ejection fraction (HFpEF). We aim to perform a meta-analysis of studies reporting long-term outcomes in HFmrEF compared with HFrEF and HFpEF.Methods and resultsData from 18 eligible large-scale studies including 126 239 patients were pooled. Patients with HFmrEF had a lower risk of all-cause death than those with HFrEF [risk ratio (RR) = 0.92; 95% CI = 0.85-0.98; P < 0.001]. This significant difference was seen in the follow-up at 1, 2, and 3 years. Patients with HFmrEF had significantly lower risk of cardiovascular (CV) deaths than HFrEF (RR = 0.77; 95% CI = 0.65-0.92; P < 0.001). Subgroup analysis showed that studies recruiting >50% of males had higher risk of deaths with HFrEF (RR = 1.15; 95% CI = 1.04-1.26; P = 0.006). When compared with HFpEF, patients with HFmrEF had comparable risk of all-cause death (RR = 1.02; 95% CI = 0.96-1.09; P = 0.53). Similarly, there were no differences in the 1, 2, and 3 year deaths; CV and non-CV deaths were insignificant between HFmrEF and HFpEF.ConclusionsThe results of the study support that HFmrEF has better prognosis than HFrEF but similar prognosis when compared with HFpEF. Gender disparity between studies seems to influence the results between HFmrEF and HFrEF. Transition in left ventricular ejection fraction (LVEF), which could not be addressed in the study, may play a decisive role in determining outcomes.

Project description:Heart failure (HF) with borderline ejection fraction was first defined in 2013 in the American College of Cardiology/American Heart Association guidelines as the presence of the typical symptoms of HF and a left ventricular ejection fraction (LVEF) of 41% to 49%. In 2016, the European Society of Cardiology specified HF with mid-range ejection fraction (HFmrEF) as LVEF of 40% to 49%. This range of LVEF is less well studied compared with HF with preserved ejection fraction (HFpEF) and HF with reduced ejection fraction (HFrEF). Although there are effective, guideline-directed medical therapies for patients with HFrEF, no therapies thus far show measurable benefit in HFpEF. Patients with HFmrEF have a clinical profile and prognosis that are closer to those of patients with HFpEF than those of HFrEF, with certain distinctions. Whether these patients represent a unique and dynamic HF group that may benefit from targeted therapies known to be beneficial in patients with HFrEF, such as neurohormonal blockade, requires further study. This review summarizes what is known about the clinical epidemiology, pathophysiology, and prognosis for patients with HFmrEF and how these features compare with the more well-studied HF groups. Although recommended treatments currently focus on aggressive management of comorbidities, we summarize the studies that identify a potential signal for beneficial therapies. Future studies are needed to not only better characterize the HFmrEF population but to also determine effective management strategies to reduce the high cardiovascular morbidity and mortality burden on this phenotype of patients with HF.

Project description:AimsAdipose tissue and inflammation may play a role in the pathophysiology of patients with heart failure (HF) with mildly reduced or preserved ejection fraction. We therefore investigated epicardial fat in patients with HF with preserved (HFpEF) and mid-range ejection fraction (HFmrEF), and related this to co-morbidities, plasma biomarkers and cardiac structure.Methods and resultsA total of 64 HF patients with left ventricular ejection fraction >40% and 20 controls underwent routine cardiac magnetic resonance examination. Epicardial fat volume was quantified on short-axis cine stacks covering the entire epicardium and was related to clinical correlates, biomarkers associated with inflammation and myocardial injury, and cardiac function and contractility on cardiac magnetic resonance. HF patients and controls were of comparable age, sex and body mass index. Total epicardial fat volume was significantly higher in HF patients compared to controls (107 mL/m2 vs. 77 mL/m2 , P <0.0001). HF patients with atrial fibrillation and/or type 2 diabetes mellitus had more epicardial fat than HF patients without these co-morbidities (116 vs. 100 mL/m2 , P =0.03, and 120 vs. 97 mL/m2 , P =0.001, respectively). Creatine kinase-MB, troponin T and glycated haemoglobin in patients with HF were positively correlated with epicardial fat volume (R =0.37, P =0.006; R =0.35, P =0.01; and R =0.42, P =0.002, respectively).ConclusionHeart failure patients had more epicardial fat compared to controls, despite similar body mass index. Epicardial fat volume was associated with the presence of atrial fibrillation and type 2 diabetes mellitus and with biomarkers related to myocardial injury. The clinical implications of these findings are unclear, but warrant further investigation.

Project description:AIMS:Heart failure (HF) patients with a mid-range ejection fraction (HFmrEF) are not well characterized. Accordingly, we examined the epidemiology, pathophysiology and clinical outcomes of HF patients with a left ventricular ejection fraction (LVEF) of 40-50%. METHODS AND RESULTS:We identified 168 patients with an LVEF between 40-50% at enrollment into a HF registry, and determined whether LVEF was improved, worsened, or the same compared to a prior LVEF. Three subgroups of HFmrEF patients were identified: HFmrEF improved (prior LVEF <40%); HFmrEF deteriorated (prior LVEF >50%); HFmrEF unchanged (prior LVEF 40-50%). The majority of patients (73%) were HFmrEF improved, 17% were HFmrEF deteriorated, and 10% were HFmrEF unchanged. The demographics of the HFmrEF cohort were heterogeneous, with more coronary artery disease in the HFmrEF improved group and more hypertension and diastolic dysfunction in the HFmrEF deteriorated group. HFmrEF improved patients had significantly (P<0.001) better clinical outcomes relative to matched patients with HF and reduced ejection fraction, and significantly (P<0.01) improved clinical outcomes relative to HFmrEF deteriorated patients, whereas clinical outcomes of the HFmrEF deteriorated subgroup of patients were not significantly different from matched HF patients with preserved ejection fraction. CONCLUSIONS:Patients with a mid-range LVEF are heterogeneous. Obtaining historical information with regard to prior LVEF allows one to identify a distinct pathophysiological substrate and clinical course for HFmrEF patients. Viewed together, these results suggest that in the modern era of HF therapeutics, the use of LVEF to categorize the pathophysiology of HF may be misleading, and argue for establishing a new taxonomy for classifying HF patients.

Project description:AimsHeart failure with mid-range ejection fraction (HFmrEF) has been proposed as a distinct HF phenotype, but whether patients on this category fare worse, similarly, or better than those with HF with reduced EF (HFrEF) or preserved EF (HFpEF) in terms of rehospitalization risks over time remains unclear.Methods and resultsWe prospectively included 2961 consecutive patients admitted for acute HF (AHF) in our institution. Of them, 158 patients died during the index admission, leaving the sample size to be 2803 patients. Patients were categorized according to their EF: HFrEF if EF ? 40% (n = 908, 32.4%); HFmrEF if EF = 41-49% (n = 449, 16.0%); and HFpEF if EF ? 50% (n = 1446, 51.6%). Covariate-adjusted incidence rate ratios (IRRs) were used to evaluate the association between EF status and recurrent all-cause and HF-related admissions. At a median follow-up of 2.6 years (inter-quartile range: 1.0-5.3), 1663 (59.3%) patients died, and 6035 all-cause readmissions were registered in 2026 patients (72.3%), 2163 of them HF related. Rates of all-cause readmission per 100 patients-years of follow-up were 150.1, 176.9, and 163.6 in HFrEF, HFmrEF, and HFpEF, respectively (P = 0.097). After multivariable adjustment, when compared with that of patients with HFrEF and HFpEF, HFmrEF status was not significantly associated with a different risk of all-cause readmissions (IRR = 0.99; 95% confidence interval [CI], 0.77-1.27; P = 0.926; and IRR = 0.93; 95% CI, 0.74-1.18; P = 0.621, respectively) or HF-related readmissions (IRR = 1.06; 95% CI, 0.77-1.46; P = 0.725; and IRR = 1.11; 95% CI, 0.82-1.50; P = 0.511, respectively).ConclusionsFollowing an admission for AHF, patients with HFmrEF had a similar rehospitalization burden and a similar risk of recurrent all-cause and HF-related admissions than had patients with HFrEF or HFpEF. Regarding morbidity risk, HFmrEF seems not to be a distinct HF phenotype.

Project description:AimsGuidelines for management of patients with heart failure with mid-range ejection fraction [HFmrEF; left ventricular EF (LVEF) 41-49%] do not exist. Disagreement exists whether HFmrEF should be considered a distinct group. The aim of this study is to examine characteristics of patients with HFmrEF with HF with reduced EF (HFrEF; LVEF ≤ 40%) or preserved EF (HFpEF; LVEF ≥ 50%).Methods and resultsWe examined data collected in the American College of Cardiology's National Cardiovascular Data Registry (NCDR) Practice Innovation and Clinical Excellence (PINNACLE) Registry® for first HF patient visits between 1 May 2008 and 30 June 2016. Analysis was performed using ANOVA F-tests (or Kruskal-Wallis tests for non-normally distributed variables) for continuous parameters and χ2 tests for nominal covariates at the first diagnosed HF visit. Given the NCDR PINNACLE Registry® is a US-based registry, we opted to define HFmrEF as per the US guidelines, which define HFmrEF as LVEF 41-49% in contrast to European guidelines, which define HFmrEF as LVEF 40-49%. Among 1 103 386 patients with available data, 36.1% (N = 398 228) had HFrEF, 7.5% (N = 82 292) had HFmrEF, and 56.5% (N = 622 866) had HFpEF. Compared with patients with HFrEF or HFpEF, patients with HFmrEF had more prevalent coronary and peripheral artery disease and more history of myocardial infarction, percutaneous coronary intervention, or coronary artery bypass surgery (all P < 0.001). Patients with HFmrEF were also more likely to have atrial fibrillation/flutter, diabetes, and chronic kidney disease and to have a history of tobacco use (both P < 0.001). Among those with EF assessment prior to this analysis, only 4.8% (N = 1032) previously had HFrEF that improved to HFmrEF; 32.9% (N = 7072) had HFpEF previously and progressed to HFmrEF. Those patients who transitioned from HFpEF to HFmrEF had considerably more complex profiles and were less aggressively managed compared with those who remained with HFmrEF (all P < 0.001).ConclusionsIn this large descriptive analysis, patients with HFmrEF had an atherothrombotic phenotype distinct from other forms of HF. Interventions aimed at treating coronary ischaemia and addressing prevalent risk factors may play a particularly important role in the management of patients with HFmrEF.

Project description:BackgroundEpicardial adipose tissue (EAT) accumulation is thought to play a role in the pathophysiology of heart failure (HF) with mid-range and preserved ejection fraction, but its effect on outcome is unknown. We evaluated the prognostic value of EAT volume measured with cardiac magnetic resonance in patients with HF with mid-range ejection fraction and HF with preserved ejection fraction.MethodsPatients enrolled in a prospective multicenter study that investigated the value of implantable loop-recorders in HF with mid-range ejection fraction and HF with preserved ejection fraction were analyzed. EAT volume was quantified with cardiac magnetic resonance. Main outcome was the composite of all-cause mortality and first HF hospitalizations. Hazard ratios (HR) and 95% CI are described per SD increase in EAT.ResultsWe studied 105 patients (mean age 72±8 years, 50% women, and mean left ventricular ejection fraction 53±8%). During median follow-up of 24 (17-25) months, 31 patients (30%) died or were hospitalized for HF. In univariable analysis, EAT was significantly associated with a higher risk of the composite outcome (HR, 1.76 [95% CI, 1.24-2.50], P=0.001), and EAT remained associated with outcome after adjustment for age, sex, and body mass index (HR, 1.61 [95% CI, 1.13-2.31], P=0.009), and after adjustment for New York Heart Association functional class and N-terminal of pro-brain natriuretic peptide (HR, 1.53 [95% CI, 1.04-2.24], P=0.03). Furthermore, EAT was associated with all-cause mortality alone (HR, 2.06 [95% CI, 1.26-3.37], P=0.004) and HF hospitalizations alone (HR, 1.54 [95% CI, 1.04-2.30], P=0.03).ConclusionsEAT accumulation is associated with adverse prognosis in patients with HF with mid-range ejection fraction and HF with preserved ejection fraction. This finding supports the importance of EAT in these patients with HF.RegistrationURL: https://www.Clinicaltrialsgov; Unique identifier: NCT01989299.
