Aim: The EMPULSE (EMPagliflozin in patients hospitalised with acUte heart faiLure who have been StabilizEd) trial showed that, compared to placebo, the sodium–glucose cotransporter 2 inhibitor empagliflozin (10 mg/day) improved clinical outcomes of patients hospitalized for acute heart failure (HF). We investigated whether efficacy and safety of empagliflozin were consistent across the spectrum of left ventricular ejection fraction (LVEF). Methods and results: A total of 530 patients hospitalized for acute de novo or decompensated HF were included irrespective of LVEF. For the present analysis, patients were classified as HF with reduced (HFrEF, LVEF ≤40%), mildly reduced (HFmrEF, LVEF 41–49%) or preserved (HFpEF, LVEF ≥50%) ejection fraction at baseline. The primary endpoint was a hierarchical outcome of death, worsening HF events (HFE) and quality of life over 90 days, assessed by the win ratio. Secondary endpoints included individual components of the primary endpoint and safety. Out of 523 patients with baseline data, 354 (67.7%) had HFrEF, 54 (10.3%) had HFmrEF and 115 (22.0%) had HFpEF. The clinical benefit (hierarchical composite of all‐cause death, HFE and Kansas City Cardiomyopathy Questionnaire total symptom score) of empagliflozin at 90 days compared to placebo was consistent across LVEF categories (≤40%: win ratio 1.35 [95% confidence interval 1.04, 1.75]; 41–49%: win ratio 1.25 [0.66, 2.37)] and ≥50%: win ratio 1.40 [0.87, 2.23], pinteraction = 0.96) with a favourable safety profile. Results were consistent across individual components of the hierarchical primary endpoint. Conclusion: The clinical benefit of empagliflozin proved consistent across LVEF categories in the EMPULSE trial. These results support early in‐hospital initiation of empagliflozin regardless of LVEF. [ABSTRACT FROM AUTHOR]

Aims: In patients hospitalized for acute heart failure (AHF) empagliflozin produced greater clinical benefit than placebo. Many patients with AHF are treated with mineralocorticoid receptor antagonists (MRAs). The interplay between empagliflozin and MRAs in AHF is yet to be explored. This study aimed to evaluate the efficacy and safety of empagliflozin versus placebo according to MRA use at baseline in the EMPULSE trial (NCT04157751). Methods and results: In this analysis all comparisons were performed between empagliflozin and placebo, stratified by baseline MRA use. The primary outcome included all‐cause death, heart failure events, and a ≥5 point difference in Kansas City Cardiomyopathy Questionnaire (KCCQ) total symptom score at 90 days, assessed using the win ratio (WR). First heart failure hospitalization or cardiovascular death was a secondary outcome. From the 530 patients randomized, 276 (52%) were receiving MRAs at baseline. MRA users were younger, had lower ejection fraction, better renal function, and higher KCCQ scores. The primary outcome showed benefit of empagliflozin irrespective of baseline MRA use (WR 1.46, 95% confidence interval [CI] 1.08–1.97 and WR 1.27, 95% CI 0.93–1.73 in MRA users and non‐users, respectively; interaction p = 0.52). The effect of empagliflozin on first heart failure hospitalization or cardiovascular death was not modified by MRA use (hazard ratio [HR] 0.58, 95% CI 0.30–1.11 and HR 0.85, 95% CI 0.47–1.52 in MRA users and non‐users, respectively; interaction p = 0.39). Investigator‐reported and severe hyperkalaemia events were infrequent (<6%) irrespective of MRA use. Conclusions: In patients admitted for AHF, initiation of empagliflozin produced clinical benefit and was well tolerated irrespective of background MRA use. These findings support the early use of empagliflozin on top of MRA therapy in patients admitted for AHF. [ABSTRACT FROM AUTHOR]

Aims Effective and safe decongestion remains a major goal for optimal management of patients with acute heart failure (AHF). The effects of the sodium–glucose cotransporter 2 inhibitor empagliflozin on decongestion-related endpoints in the EMPULSE trial (NCT0415775) were evaluated. Methods and results A total of 530 patients hospitalized for AHF were randomized 1:1 to either empagliflozin 10 mg once daily or placebo for 90 days. The outcomes investigated were: weight loss (WL), WL adjusted for mean daily loop diuretic dose (WL-adjusted), area under the curve of change from baseline in N-terminal pro-B-type natriuretic peptide levels, hemoconcentration, and clinical congestion score after 15, 30, and 90 days of treatment. Compared with placebo, patients treated with empagliflozin demonstrated significantly greater reductions in all studied markers of decongestion at all time-points, adjusted mean differences (95% confidence interval) at Days 15, 30, and 90 were: for WL −1.97 (−2.86, −1.08), −1.74 (−2.73, −0.74); −1.53 (−2.75, −0.31) kg; for WL-adjusted: −2.31 (−3.77, −0.85), −2.79 (−5.03, −0.54), −3.18 (−6.08, −0.28) kg/40 mg furosemide i.v. or equivalent; respectively (all P < 0.05). Greater WL at Day 15 (i.e. above the median WL in the entire population) was associated with significantly higher probability for clinical benefit at Day 90 (hierarchical composite of all-cause death, heart failure events, and a 5-point or greater difference in Kansas City Cardiomyopathy Questionnaire total symptom score change from baseline to 90 days) with the win ratio of 1.75 (95% confidence interval 1.37, 2.23; P < 0.0001). Conclusion Initiation of empagliflozin in patients hospitalized for AHF resulted in an early, effective and sustained decongestion which was associated with clinical benefit at Day 90.

Aims: Patients hospitalized for acute heart failure (HF) could be enrolled in EMPULSE (NCT04157751) upon haemodynamic stabilization and between 24 h and 5 days after hospital admission. The timing of treatment initiation may influence the efficacy and safety of drugs such as empagliflozin. The aim of this study was to evaluate patient characteristics, clinical events, and treatment effects according to time from admission to randomization. Methods and results: The EMPULSE population was dichotomized by median time from hospital admission to randomization (1–2 days vs. 3–5 days). The primary outcome was a hierarchical composite endpoint of time to all‐cause death, number of HF events, time to first HF event, and a ≥5‐point difference in Kansas City Cardiomyopathy Questionnaire total symptom score change from baseline after 90 days, analysed using the win ratio (WR) method. Patients randomized later (3–5 days, average time 3.9 days; n = 312) had a higher risk of experiencing clinical events than patients randomized earlier (1–2 days, average time 1.7 days; n = 215). The treatment effect favoured empagliflozin versus placebo in patients randomized later (3–5 days: WR 1.69, 95% confidence interval [CI] 1.26–2.25) but was attenuated in patients randomized earlier (1–2 days: WR 1.04, 95% CI 0.74–1.44) (interaction p = 0.029). A similar pattern was observed for the composite of HF hospitalization or cardiovascular death and all‐cause hospitalizations (interaction p < 0.1 for both). The reduction of N‐terminal pro‐B‐type natriuretic peptide levels was more pronounced with empagliflozin among patients randomized later than in patients randomized earlier (interaction p = 0.004). Conclusions: Among patients hospitalized for acute HF enrolled in EMPULSE, those randomized later after hospital admission (3–5 days) experienced greater clinical benefit with empagliflozin than those randomized earlier (1–2 days). These findings should be confirmed in future studies before clinical application. [ABSTRACT FROM AUTHOR]

Background: Patients hospitalized for acute heart failure experience poor health status, including a high burden of symptoms and physical limitations, and poor quality of life. SGLT2 (sodium-glucose cotransporter 2) inhibitors improve health status in chronic heart failure, but their effect on these outcomes in acute heart failure is not well characterized. We investigated the effects of the SGLT2 inhibitor empagliflozin on symptoms, physical limitations, and quality of life, using the Kansas City Cardiomyopathy Questionnaire (KCCQ) in the EMPULSE trial (Empagliflozin in Patients Hospitalized With Acute Heart Failure Who Have Been Stabilized).Methods: Patients hospitalized for acute heart failure were randomized to empagliflozin 10 mg daily or placebo for 90 days. The KCCQ was assessed at randomization and 15, 30, and 90 days. The effects of empagliflozin on the primary end point of clinical benefit (hierarchical composite of all-cause death, heart failure events, and a 5-point or greater difference in KCCQ Total Symptom Score [TSS] change from baseline to 90 days) were examined post hoc across the tertiles of baseline KCCQ-TSS. In prespecified analyses, changes (randomization to day 90) in KCCQ domains, including TSS, physical limitations, quality of life, clinical summary, and overall summary scores were evaluated using a repeated measures model.Results: In total, 530 patients were randomized (265 each arm). Baseline KCCQ-TSS was low overall (mean [SD], 40.8 [24.0] points). Empagliflozin-treated patients experienced greater clinical benefit across the range of KCCQ-TSS, with no treatment effect heterogeneity (win ratio [95% CIs] from lowest to highest tertile: 1.49 [1.01-2.20], 1.37 [0.94-1.99], and 1.48 [1.00-2.20], respectively; P for interaction=0.94). Beneficial effects of empagliflozin on health status were observed as early as 15 days and persisted through 90 days, at which point empagliflozin-treated patients experienced a greater improvement in KCCQ TSS, physical limitations, quality of life, clinical summary, and overall summary (placebo-adjusted mean differences [95% CI]: 4.45 [95% CI, 0.32-8.59], P=0.03; 4.80 [95% CI, 0.00-9.61], P=0.05; 4.66 [95% CI, 0.32-9.01], P=0.04; 4.85 [95% CI, 0.77-8.92], P=0.02; and 4.40 points [95% CI, 0.33-8.48], P=0.03, respectively).Conclusions: Initiation of empagliflozin in patients hospitalized for acute heart failure produced clinical benefit regardless of the degree of symptomatic impairment at baseline, and improved symptoms, physical limitations, and quality of life, with benefits seen as early as 15 days and maintained through 90 days.Registration: URL: https://www.Clinicaltrials: gov; Unique identifier: NCT0415775.
