IntroductionDisturbed blood flow, characterized by high retrograde and oscillatory shear rate (SR), is associated with a proatherogenic phenotype. The impact of disturbed blood flow in patients with heart failure with reduced ejection fraction (HFrEF) remains unknown. We tested the hypothesis that acute elevation to retrograde and oscillatory SR provoked by local circulatory occlusion would increase endothelial microparticles (EMPs) and decrease brachial artery flow-mediated dilation (FMD) in patients with HFrEF.MethodsEighteen patients with HFrEF aged 55 ± 2 years, with left ventricular ejection fraction (LVEF) 26 ± 1%, and 14 control subjects aged 49 ± 2 years with LVEF 65 ± 1 randomly underwent experimental and control sessions. Brachial artery FMD (Doppler) was evaluated before and after 30 min of disturbed forearm blood flow provoked by pneumatic cuff (Hokanson) inflation to 75 mm Hg. Venous blood samples were collected at rest, after 15 and 30 min of disturbed blood flow to assess circulating EMP levels (CD42b−/CD31+; flow cytometry).ResultsAt rest, FMD was lower in patients with HFrEF compared with control subjects (P < 0.001), but blood flow patterns and EMPs had no differences (P > 0.05). The cuff inflation provoked a greater retrograde SR both groups (P < 0.0001). EMPs responses to disturbed blood flow significantly increased in patients with HFrEF (P = 0.03). No changes in EMPs were found in control subjects (P > 0.05). Disturbed blood flow decreased FMD both groups. No changes occurred in control condition.ConclusionCollectively, our findings suggest that disturbed blood flow acutely decreases FMD and increases EMP levels in patients with HFrEF, which may indicate that this set of patients are vulnerable to blood flow disturbances.

AbstractAngiotensin receptor-neprilysin inhibitor (ARNI) and sodium–glucose co-transporter-2 inhibitor (SGLT2i) have shown benefits in diabetic patients with heart failure with reduced ejection fraction (HFrEF). However, their combined effect has not been revealed. We retrospectively identified diabetic patients with HFrEF who were prescribed an ARNI and/or SGLT2i. The patients were divided into groups treated with both ARNI and SGLT2i (group 1), ARNI but not SGLT2i (group 2), SGLT2i but not ARNI (group 3), and neither ARNI nor SGLT2i (group 4). After propensity score-matching, the occurrence of hospitalization for heart failure (HHF), cardiovascular mortality, and changes in echocardiographic parameters were analyzed. Of the 206 matched patients, 92 (44.7%) had to undergo HHF and 43 (20.9%) died of cardiovascular causes during a median 27.6 months of follow-up. Patients in group 1 exhibited a lower risk of HHF and cardiovascular mortality compared to those in the other groups. Improvements in the left ventricular ejection fraction and E/e′ were more pronounced in group 1 than in groups 2, 3 and 4. These echocardiographic improvements were more prominent after the initiation of ARNI, compare to the initiation of SGLT2i. In diabetic patients with HFrEF, combination of ARNI and SGT2i showed significant improvement in cardiac function and prognosis. ARNI-SGLT2i combination therapy may improve the clinical course of HFrEF in diabetic patients.

Background: Among patients with heart failure (HF) with reduced ejection fraction (EF), improvements in left ventricular EF (LVEF) are associated with better outcomes and remain an important treatment goal. Patient factors associated with LVEF improvement in routine clinical practice have not been clearly defined. Methods: CHAMP-HF (Change the Management of Patients with Heart Failure) is a prospective registry of outpatients with HF with reduced EF. Assessments of LVEF are recorded when performed for routine care. We analyzed patients with both baseline and ≥1 follow-up LVEF assessments to describe factors associated with LVEF improvement. Results: In CHAMP-HF, 2623 patients had a baseline and follow-up LVEF assessment. The median age was 67 (interquartile range, 58–75) years, 40% had an ischemic cardiomyopathy, and median HF duration was 2.8 years (0.7–6.8). Median LVEF was 30% (23–35), and median change on follow-up was 4% (−2 to −13); 19% of patients had a decrease in LVEF, 31% had no change, 49% had a ≥5% increase, and 34% had a ≥10% increase. In a multivariable model, the following factors were associated with ≥5% LVEF increase: shorter HF duration (odds ratio [OR], 1.21 [95% CI, 1.17–1.25]), no implantable cardioverter defibrillator (OR, 1.46 [95% CI, 1.34–1.55]), lower LVEF (OR, 1.15 [95% CI, 1.10–1.19]), nonischemic cardiomyopathy (OR, 1.24 [95% CI, 1.09–1.36]), and no coronary disease (OR, 1.20 [95% CI, 1.03–1.35]). Conclusions: In a large cohort of outpatients with chronic HF with reduced EF, improvements in LVEF were common. Common baseline cardiac characteristics identified a population that was more likely to respond over time. These data may inform clinical decision making and should be the basis for future research on myocardial recovery.

We describe the characteristics of ambulatory patients with heart failure with reduced ejection fraction (HFrEF) in the Gulf region (Middle East) and the implementation of guideline-recommended treatments. We included 2427 HFrEF outpatients (mean age 59 ± 13 years, 75% males and median left ventricular ejection fraction [LVEF] of 30%). A high proportion of patients received guideline-recommended medications (angiotensin-converting enzyme inhibitor [ACEI]/angiotensin receptor blocker [ARB]/angiotensin receptor-neprilysin inhibitor [ARNI] 87%, β-blocker 91%, mineralocorticoid antagonist [MRA] 64%). However, only a minority of patients received guideline-recommended target doses (ACEI/ARB/ARNI 13%, β-blocker 27%, and MRA 4.4%). Old age was a significant independent predictor for not prescribing treatment ( P < .001 for ACEI/ARB/ARNI and MRA; and P = .002 for β-blockers). Other independent predictors were chronic kidney disease (for both ACEI/ARB/ARNI and MRA, P < .001) and higher LVEF ( P = .014 for β-blockers and P < .001 for MRA). Patients with HFrEF managed by heart failure specialists more often received recommended target doses of ACEI/ARB/ARNI (40% vs 11%, P < .001) and β-blockers (56% vs 26%, P < .001) compared to those treated by general cardiologists. Although the majority of our patients with HFrEF received guideline-recommended medications, the doses they were prescribed were suboptimal. Understanding the reasons behind this is important for improved practice.

Abstract Background The presence of atrial fibrillation (AF) has been demonstrated to be associated with poor clinical outcomes in heart failure patients with reduced ejection fraction. Objective This study aimed to elucidate the impact of the presence of atrial fibrillation (AF) on the clinical characteristics, therapeutics, and outcomes in patients with heart failure and preserved ejection fraction (HFpEF). Methods PURSUIT-HFpEF is a multicenter prospective observational study including patients hospitalized for acute heart failure with left ventricular ejection fraction of >50%. Patients with acute coronary syndrome or severe valvular disease were excluded. Results Of 486 HFpEF patients (age, 80.8±9.0 years old; male, 47%) from 24 cardiovascular centers, 199 (41%) had AF on admission. Patients with AF had lower systolic blood pressures (142±27 vs. 155±35mmHg, p<0.0001) and higher heart rates (91±29 vs. 82±26bpm, p<0.0001) than those without. There was no difference in the usage of inotropes or mechanical ventilation between the 2 groups. A higher quality of life score (EQ5D, 0.72±0.27 vs. 0.63±0.30, p=0.002) was observed at discharge in patients with than without AF. In addition, AF patients tended to demonstrate lower in-hospital mortality rates (0.5% vs. 2.4%, p=0.09) and shorter hospital stays (20.3±12.1 vs. 22.6±18.4 days, p=0.09) than those without. During a mean follow up of 360±111 days, mortality (14.1% vs. 15.3) and heart failure re-hospitalization rates (13.1% vs. 13.9%) were comparable between the 2 groups. Conclusion In contrast to heart failure patients with reduced ejection fraction, AF on admission was not associated with poor long-term clinical outcomes among HFpEF patients. Several in-hospital outcomes were better in patients with AF than in those without. Acknowledgement/Funding None

<b><i>Background:</i></b> In patients with heart failure (HF) and reduced ejection fraction (HFrEF) with or without type 2 diabetes mellitus, the sodium-glucose cotransporter 2 inhibitor (SGLT2i) dapagliflozin was recently shown to reduce the risk of worsening HF or death from cardiovascular causes in the dapagliflozin in patients with heart failure and reduced ejection fraction (DAPA-HF) trial. Our goal was to investigate how many patients in a real-world setting would be eligible for dapagliflozin according to the DAPA-HF enrolment criteria. <b><i>Methods:</i></b> This is a single-center retrospective study enrolling consecutive, unselected patients followed up in an HF clinic from 2013 to 2019. Key DAPA-HF inclusion criteria (i.e., left ventricular ejection fraction [LVEF] ≤40% and NT-proBNP ≥600 pg/mL [or ≥900 pg/mL if atrial fibrillation]) and exclusion criteria (estimated glomerular filtration rate [eGFR] &#x3c;30 mL/kg/1.73 m<sup>2</sup> and systolic blood pressure [SBP] &#x3c;95 mm Hg) were considered. <b><i>Results:</i></b> Overall, 479 patients (age 76 ± 13 years; 50.5% male; 78.9% hypertensive; 45.1% with an eGFR &#x3c;60 mL/min/1.73 m<sup>2</sup>; 36.5% with TD2M; and 33.5% with ischaemic HF) were assessed. The median SBP was 128.5 (112.0–146.0) mm Hg, mean eGFR was 50.8 ± 23.7 mL/min/1.73 m<sup>2</sup>, and median NT-proBNP was 2,183 (IQR 1,010–5,310) pg/mL. Overall, 155 (32.4%) patients had LVEF ≤40%. According to the DAPA-HF trial key criteria, 90 patients (18.8%) would be eligible for dapagliflozin. The remainder would be excluded due to LVEF &#x3e;40% (67.6%), eGFR &#x3c;30 mL/min/1.73 m<sup>2</sup> (19.4%), NT-proBNP below the cutoff (16.7%), and/or SBP &#x3c;95 mm Hg (6.5%). If we center the analysis to those with LVEF ≤40%, 58.1% would be eligible for dapagliflozin. The remainder would be excluded due to an eGFR &#x3c;30 mL/min/1.73 m<sup>2</sup> (20%), NT-proBNP below the cutoff (16.1%), and/or SBP &#x3c;95 mm Hg (8.4%). <b><i>Conclusion:</i></b> Roughly half of our real-world HFrEF cohort would be eligible for dapagliflozin according to the key criteria of the DAPA-HF trial. The main reason for non-eligibility was an eGFR &#x3c;30 mL/min/1.73 m<sup>2</sup>. However, two-thirds of patients had LVEF &#x3e;40%. These findings show that dapagliflozin is a promising complementary new drug in the therapeutic armamentarium of most patients with HFrEF, while highlighting the urgent need for disease-modifying drugs in mid-range and preserved LVEF and the need to assess the efficacy and safety of SLGT2i in advanced kidney disease patients. The results of ongoing SGLT2i trials in these LVEF subgroups are eagerly awaited.

Abstract Aims We assessed the efficacy of add-on drugs in patients with heart failure with reduced ejection fraction (HFrEF) and concomitant chronic kidney disease (CKD) already receiving neurohormonal inhibition (NEUi). Methods and results The literature was systematically searched for phase 3 randomized controlled trials (RCTs) involving ≥90% patients with left ventricular ejection fraction &lt;45%, of whom &lt;30% were acutely decompensated, and with published information about the subgroup of estimated glomerular filtration rate &lt;60 ml/min/1.73 m2. Six RCTs were included in a study-level network meta-analysis evaluating the effect of NEUi, ivabradine, angiotensin receptor-neprilysin inhibitor (ARNI), sodium-glucose cotransporter-2 inhibitors (SGLT2i), vericiguat, and omecamtiv mecarbil (OM) on a composite outcome of cardiovascular death or hospitalization for heart failure. In a fixed-effects model, SGLT2i (HR: 0.78, 95% CrI: 0.69–0.89), ARNI (HR: 0.79, 95% CrI: 0.69–0.90), and ivabradine (HR: 0.82, 95% CrI: 0.69–0.98) decreased the risk of the composite outcome vs. NEUi, whereas OM did not (HR: 0.98, 95% CrI: 0.89–1.10). A trend for improved outcome was also found for vericiguat (HR: 0.90, 95% CrI: 0.80–1.00). In indirect comparisons, both SLGT2i (HR: 0.80, 95% CrI: 0.68–0.94) and ARNI (HR: 0.80, 95% CrI: 0.68–0.95) reduced the risk vs. OM; furthermore, there was a trend for a greater benefit of SGLT2i vs. vericiguat (HR: 0.88, 95% CrI: 0.73–1.00) and ivabradine vs. OM (HR: 0.84, 95% CrI: 0.68–1.00). Results were comparable in a random-effects model and in sensitivity analyses. SUCRA scores were 81.8%, 80.8%, 68.9%, 44.2%, 16.6%, and 7.8% for SGLT2i, ARNI, ivabradine, vericiguat, OM, and NEUi, respectively. Conclusions Expanding pharmacotherapy beyond NEUi improves outcomes in HFrEF with CKD. 633 Figure

Background: Heart failure with improved ejection fraction (HFimpEF) is classified as a new type of heart failure, and its prevalence and prognosis are not consistent in previous studies. There is no systematic review and meta-analysis regarding the prevalence and prognosis of the HFimpEF.Method: A systematic search was performed in MEDLINE, EMBASE, and Cochrane Library from inception to May 22, 2021 (PROSPERO registration: CRD42021260422). Studies were included for analysis if the prognosis of mortality or hospitalization were reported in HFimpEF or in patients with heart failure with recovered ejection fraction (HFrecEF). The primary outcome was all-cause mortality. Cardiac hospitalization, all-cause hospitalization, and composite events of mortality and hospitalization were considered as secondary outcomes.Result: Nine studies consisting of 9,491 heart failure patients were eventually included. During an average follow-up of 3.8 years, the pooled prevalence of HFimpEF was 22.64%. HFimpEF had a lower risk of mortality compared with heart failure patients with reduced ejection fraction (HFrEF) (adjusted HR: 0.44, 95% CI: 0.33–0.60). HFimpEF was also associated with a lower risk of cardiac hospitalization (HR: 0.40, 95% CI: 0.20–0.82) and the composite endpoint of mortality and hospitalization (HR: 0.56, 95% CI: 0.44–0.73). Compared with patients with preserved ejection fraction (HFpEF), HFimpEF was associated with a moderately lower risk of mortality (HR: 0.42, 95% CI: 0.32–0.55) and hospitalization (HR: 0.73, 95% CI: 0.58–0.92).Conclusion: Around 22.64% of patients with HFrEF would be treated to become HFimpEF, who would then obtain a 56% decrease in mortality risk. Meanwhile, HFimpEF is associated with lower heart failure hospitalization. Further studies are required to explore how to promote left ventricular ejection fraction improvement and improve the prognosis of persistent HFrEF in patients.Systematic Review Registration:https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42021260422, identifier: CRD42021260422.
