Item Biased ligand of the angiotensin II type 1 receptor in patients with acute heart failure: a randomized, double-blind, placebo-controlled, phase IIB, dose ranging trial (BLAST-AHF)(Oxford University Press, 2017-08-07) Pang, Peter S.; Butler, Javed; Collins, Sean P.; Cotter, Gad; Davison, Beth A.; Ezekowitz, Justin A.; Filippatos, Gerasimos; Levy, Phillip D.; Metra, Marco; Ponikowski, Piotr; Teerlink, John R.; Voors, Adriaan A.; Bharucha, David; Goin, Kathleen; Soergel, David G.; Felker, G. Michael; Emergency Medicine, School of MedicineAims: Currently, no acute heart failure (AHF) therapy definitively improves outcomes. Reducing morbidity and mortality from acute heart failure (AHF) remains an unmet need. TRV027 is a novel 'biased' ligand of the angiotensin II type 1 receptor (AT1R), selectively antagonizing the negative effects of angiotensin II, while preserving the potential pro-contractility effects of AT1R stimulation. BLAST-AHF was designed to determine the safety, efficacy, and optimal dose of TRV027 to advance into future studies. Methods and results: BLAST-AHF was a multi-centre, international, randomized, double-blind, placebo-controlled, parallel group, phase IIb dose-ranging study, enrolling patients with AHF into 4 groups: placebo, 1, 5, or 25 mg/h of TRV027. Treatment was by IV infusion for 48-96 h. The primary composite endpoint was comprised of the following: (i) time from baseline to death through day 30, (ii) time from baseline to heart failure re-hospitalization through day 30, (iii) the first assessment time point following worsening heart failure through day 5, (iv) change in dyspnea visual analogue scale (VAS) score calculated as the area under the curve (AUC) representing the change from baseline over time from baseline through day 5, and (v) length of initial hospital stay (in days) from baseline. Analyses were by modified intention-to-treat. Overall, 621 patients were enrolled. After 254 patients, a pre-specified interim analysis resulted in several protocol changes, including a lower blood pressure inclusion criterion as well as a new allocation scheme of 2:1:2:1, overweighting both placebo, and the 5 mg/h dose. TRV027 did not confer any benefit over placebo at any dose with regards to the primary composite endpoint or any of the individual components. There were no significant safety issues with TRV027. Conclusion: In this phase IIb dose-ranging AHF study, TRV027 did not improve clinical status through 30-day follow-up compared with placebo.Item Characteristics and clinical outcomes of patients with acute heart failure with a supranormal left ventricular ejection fraction(Wiley, 2023) van Essen, Bart J.; Tromp, Jasper; Ter Maaten, Jozine M.; Greenberg, Barry H.; Gimpelewicz, Claudio; Felker, G. Michael; Davison, Beth A.; Severin, Thomas; Pang, Peter S.; Cotter, Gad; Teerlink, John R.; Metra, Marco; Voors, Adriaan A.; Emergency Medicine, School of MedicineAim: Recent data suggest that guideline-directed medical therapy of patients with heart failure (HF) with reduced ejection fraction (HFrEF) might improve clinical outcomes in patients with HF up to a left ventricular ejection fraction (LVEF) of 55-65%, whereas patients with higher LVEF do not seem to benefit. Recent data have shown that LVEF may have a U-shaped relation with outcome, with poorer outcome also in patients with supranormal values. This suggests that patients with supranormal LVEF may be a distinctive group of patients. Methods and results: RELAX-AHF-2 was a multicentre, placebo-controlled trial on the effects of serelaxin on 180-day cardiovascular (CV) mortality and worsening HF at day 5 in patients with acute HF. Echocardiograms were performed at hospital admission in 6128 patients: 155 (2.5%) patients were classified as HF with supranormal ejection fraction (HFsnEF; LVEF >65%), 1440 (23.5%) as HF with preserved ejection fraction (HFpEF; LVEF 50-65%), 1353 (22.1%) as HF with mildly reduced ejection fraction (HFmrEF; LVEF 41-49%) and 3180 (51.9%) as HFrEF (LVEF <40%). Patients with HFsnEF compared to HFpEF were more often women, had higher prevalence of non-ischaemic HF, had lower levels of natriuretic peptides, were less likely to be treated with beta-blockers and had higher blood urea nitrogen plasma levels. All-cause mortality was not statistically different between groups, although patients with HFsnEF had the highest numerical rate. A declining trend was seen in the proportion of 180-day deaths due to CV causes from HFrEF (290/359, 80.8%) to HFsnEF (14/24, 58.3%). The reverse was observed with death from non-CV causes. No treatment effect of serelaxin was observed in any of the subgroups. Conclusions: In this study, only 2.5% of patients were classified as HFsnEF. HFsnEF was primarily characterized by female sex, lower natriuretic peptides and a higher risk of non-CV death.Item Day vs night: Does time of presentation matter in acute heart failure? A secondary analysis from the RELAX-AHF trial(Elsevier, 2017-05) Pang, Peter S.; Teerlink, John R.; Boer-Martins, Leandro; Gimpelewicz, Claudio; Davison, Beth A.; Wang, Yi; Voors, Adriaan A.; Severin, Thomas; Ponikowski, Piotr; Hua, Tsushung A.; Greenberg, Barry H.; Filippatos, Gerasimos; Felker, G. Michael; Cotter, Gad; Metra, Marco; Department of Emergency Medicine, IU School of MedicineBackground Signs and symptoms of heart failure can occur at any time. Differences between acute heart failure (AHF) patients who present at nighttime vs daytime and their outcomes have not been well studied. Our objective was to determine if there are differences in baseline characteristics and clinical outcomes between AHF patients presenting during daytime vs nighttime hours within an international, clinical trial. Methods This is a post hoc analysis of the RELAX AHF trial, which randomized 1,161 AHF patients to serelaxin vs placebo, both in addition to usual AHF therapy. Prespecified end points of the primary trial were used: dyspnea, 60-day heart failure/renal failure rehospitalization or cardiovascular (CV) death, and 180-day CV death. Both unadjusted and adjusted analyses for outcomes stratified by daytime vs nighttime presentation were performed. Results Of the 1,161 RELAX-AHF patients, 775 (66.8%) patients presented during daytime and 386 (33.2%) at nighttime. Baseline characteristics were largely similar, although daytime patients were more likely to be male, have greater baseline body weight, have higher New York Heart Association class, have history of atrial fibrillation, and have more peripheral edema compared with nighttime patients. No differences in dyspnea relief or 60-day outcomes were observed. However, daytime presentation was associated with greater risk for 180-day CV death after adjustment (hazard ratio 2.28, 95% CI 1.34-3.86; c statistic = 0.82, 95% CI 0.78-0.86). Conclusion In this secondary analysis of the RELAX-AHF trial, baseline characteristics suggest that daytime-presenting patients may have more gradual worsening of chronic HF. Patients with AHF who presented at night had less risk for 180-day CV death, but similar risk for 60-day CV death or rehospitalization and symptom improvement for patients who presented during the daytime.Item Effects of a Novel Nitroxyl Donor in Acute Heart Failure: The STAND-UP AHF Study(Elsevier, 2021) Felker, G. Michael; McMurray, John J. V.; Cleland, John G.; O’Connor, Christopher M.; Teerlink, John R.; Voors, Adriaan A.; Belohlavek, Jan; Böhm, Michael; Borentain, Maria; Bueno, Hector; Cole, Robert T.; DeSouza, Mary M.; Ezekowitz, Justin A.; Filippatos, Gerasimos; Lang, Ninian N.; Kessler, Paul D.; Martinez, Felipe A.; Mebazaa, Alex; Metra, Marco; Mosterd, Arend; Pang, Peter S.; Ponikowski, Piotr; Sato, Naoki; Seiffert, Dietmar; Ye, June; Emergency Medicine, School of MedicineObjectives: The primary objective was to identify well-tolerated doses of cimlanod in patients with acute heart failure (AHF). Secondary objectives were to identify signals of efficacy, including biomarkers, symptoms, and clinical events. Background: Nitroxyl (HNO) donors have vasodilator, inotropic and lusitropic effects. Bristol-Myers Squibb-986231 (cimlanod) is an HNO donor being developed for acute heart failure (AHF). Methods: This was a phase IIb, double-blind, randomized, placebo-controlled trial of 48-h treatment with cimlanod compared with placebo in patients with left ventricular ejection fraction ≤40% hospitalized for AHF. In part I, patients were randomized in a 1:1 ratio to escalating doses of cimlanod or matching placebo. In part II, patients were randomized in a 1:1:1 ratio to either of the 2 highest tolerated doses of cimlanod from part I or placebo. The primary endpoint was the rate of clinically relevant hypotension (systolic blood pressure <90 mm Hg or patients became symptomatic). Results: In part I (n = 100), clinically relevant hypotension was more common with cimlanod than placebo (20% vs. 8%; relative risk [RR]: 2.45; 95% confidence interval [CI]: 0.83 to 14.53). In part II (n = 222), the incidence of clinically relevant hypotension was 18% for placebo, 21% for cimlanod 6 μg/kg/min (RR: 1.15; 95% CI: 0.58 to 2.43), and 35% for cimlanod 12 μg/kg/min (RR: 1.9; 95% CI: 1.04 to 3.59). N-terminal pro-B-type natriuretic peptide and bilirubin decreased during infusion of cimlanod treatment compared with placebo, but these differences did not persist after treatment discontinuation. Conclusions: Cimlanod at a dose of 6 μg/kg/min was reasonably well-tolerated compared with placebo. Cimlanod reduced markers of congestion, but this did not persist beyond the treatment period.Item Effects of serelaxin in acute heart failure patients with renal impairment: results from RELAX-AHF(Springer, 2016-09) Liu, Licette C. Y.; Voors, Adriaan A.; Teerlink, John R.; Cotter, Gad; Davison, Beth A.; Felker, G. Michael; Filippatos, Gerasimos; Chen, Yakuan; Greenberg, Barry H.; Ponikowski, Piotr; Pang, Peter S.; Prescott, Margaret F.; Hua, Tsushung A.; Severin, Thomas M.; Metra, Marco; Department of Emergency Medicine, IU School of MedicineBackground Serelaxin showed beneficial effects on clinical outcome and trajectories of renal markers in patients with acute heart failure. We aimed to study the interaction between renal function and the treatment effect of serelaxin. Methods In the current post hoc analysis of the RELAX-AHF trial, we included all patients with available estimated glomerular filtration rate (eGFR) at baseline (n = 1132). Renal impairment was defined as an eGFR <60 ml/min/1.73 m2 estimated by creatinine. Results 817 (72.2 %) patients had a baseline eGFR <60 ml/min/1.73 m2. In placebo-treated patients, baseline renal impairment was related to a higher 180 day cardiovascular (HR 3.12, 95 % CI 1.33–7.30) and all-cause mortality (HR 2.81, 95 % CI 1.34–5.89). However, in serelaxin-treated patients, the risk of cardiovascular and all-cause mortality was less pronounced (HR 1.19, 95 % CI 0.54 –2.64; p for interaction = 0.106, and HR 1.15 95 % CI 0.56–2.34 respectively; p for interaction = 0.088). In patients with renal impairment, treatment with serelaxin resulted in a more pronounced all-cause mortality reduction (HR 0.53, 95 % CI 0.34–0.83), compared with patients without renal impairment (HR 1.30, 95 % CI 0.51–3.29). Conclusion Renal dysfunction was associated with higher cardiovascular and all-cause mortality in placebo-treated patients, but not in serelaxin-treated patients. The observed reduction in (cardiovascular) mortality in RELAX-AHF was more pronounced in patients with renal dysfunction. These observations need to be confirmed in the ongoing RELAX-AHF-2 trial.Item Effects of serelaxin on the outcome of patients with or without substantial peripheral edema: A subgroup analysis from the RELAX-AHF trial(Elsevier, 2017-08) Gimpelewicz, Claudio; Metra, Marco; Cleland, John G. F.; Szecsödy, Peter; Chang Wun, Chuan-Chuan; Boer-Martins, Leandro; Cotter, Gad; Davison, Beth A.; Felker, G. Michael; Filippatos, Gerasimos; Greenberg, Barry H.; Pang, Peter S.; Ponikowski, Piotr; Severin, Thomas; Voors, Adrian A.; Teerlink, John R.; Department of Emergency Medicine, IU School of MedicineBackground Acute heart failure (AHF) is a heterogeneous disorder, with most of the patients presenting with breathlessness along with varying degrees of peripheral edema. The presence of peripheral edema suggests that volume overload is the cause of decompensation leading to AHF, whereas breathlessness in the absence of edema may reflect a “vascular phenotype.” This analysis investigated the characteristics, therapeutic response, and outcome of patients with AHF, with and without overt peripheral edema in the RELAX-AHF trial. Methods Physician-assessed edema scores at baseline were used to categorize the population into those with no/mild edema (score 0 or 1+) and moderate/severe edema (score 2+ or 3+). The effect of serelaxin vs placebo was assessed within each subgroup. Results Patients with moderate/severe edema (n = 583; 50.5%) were more likely to have severe dyspnea, orthopnea (>30°), rales (≥1/3), and elevated jugular venous pressure (>6 cm) than the patients with little or no peripheral edema (n=571; 49.5%). The relative benefits of serelaxin in terms of reduction in breathlessness, lower diuretic requirements, decreased length of initial hospital stay and days in intensive care unit/cardiac care unit, and improved prognosis (180-day cardiovascular and all-cause mortality) were generally similar for patients with or without peripheral edema. However, because patients with moderate/severe peripheral edema had worse outcomes, the absolute benefit was generally greater than in patients with no/mild edema. Conclusions Overall, patients with AHF and moderate/severe peripheral edema have a worse prognosis but appear to receive similar relative benefit and perhaps greater absolute benefit from serelaxin administration.Item Growth differentiation factor 15 (GDF-15) in patients admitted for acute heart failure: results from the RELAX-AHF study(Wiley, 2015-11) Cotter, Gad; Voors, Adriaan A.; Prescott, Margaret F.; Felker, G. Michael; Filippatos, Gerasimos; Greenberg, Barry H.; Pang, Peter S.; Ponikowski, Piotr; Milo, Olga; Hua, Tsushung A.; Qian, Min; Severin, Thomas M.; Teerlink, John R.; Metra, Marco; Davison, Beth A.; Department of Emergency Medicine, IU School of MedicineBackground Growth differentiation factor 15 (GDF-15) was found to be upregulated in patients with chronic heart failure (HF) and associated with disease severity, however, data on patients with acute heart failure (AHF) is lacking. Methods and results Levels of GDF-15 were measured at pre-specified time-points (baseline and at days 2, 5, 14, and 60) in patients enrolled in the placebo-controlled RELAXin in Acute Heart Failure (RELAX-AHF) study, which examined the effect of serelaxin in 1161 patients with AHF, systolic blood pressure >125 mmHg, and mild to moderate renal impairment. Neither baseline nor changes in GDF-15 were associated with the degree of dyspnoea or dyspnoea relief. After adjustment for baseline characteristics, baseline GDF-15 was not associated with the composite endpoint of heart failure or renal failure (HF/RF) readmission at 60 days/cardiovascular (CV) death or CV death at 180 days. In contrast, larger increases in GDF-15 levels at days 2 and 14 were associated with a greater risk of 60-day HF/RF rehospitalizations/CV death and CV death at 180 days. Serelaxin treatment was associated with significantly larger decreases of GDF-15 at days 2 and 5 than placebo. Conclusions In AHF patients enrolled in the RELAX-AHF study, increases in GDF-15 levels, but not baseline measurements, were associated with a greater likelihood of adverse outcomes. Serelaxin administration was associated with greater decreases in GDF-15 compared with placebo.Item Medical Misinformation: Vet the Message!(Oxford, 2019-02-01) Hill, Joseph A; Agewall, Stefan; Baranchuk, Adrian; Booz, George W; Borer, Jeffrey S; Camici, Paolo G; Chen, Peng-Sheng; Dominiczak, Anna F; Erol, Çetin; Grines, Cindy L; Gropler, Robert; Guzik, Tomasz J; Heinemann, Markus K; Iskandrian, Ami E; Knight, Bradley P; London, Barry; Lüscher, Thomas F; Metra, Marco; Musunuru, Kiran; Nallamothu, Brahmajee K; Natale, Andrea; Saksena, Sanjeev; Picard, Michael H; Rao, Sunil V; Remme, Willem J; Rosenson, Robert S; Sweitzer, Nancy K; Timmis, Adam; Vrints, Christiaan; Medicine, School of MedicineItem Neutrophil-to-Lymphocyte Ratio and Outcomes in Patients Admitted for Acute Heart Failure (As Seen in the BLAST-AHF, Pre-RELAX-AHF, and RELAX-AHF Studies)(Elsevier, 2022) Davison, Beth A.; Takagi, Koji; Edwards, Christopher; Adams, Kirkwood F., Jr.; Butler, Javed; Collins, Sean P.; Dorobantu, Maria I.; Ezekowitz, Justin A.; Filippatos , Gerasimos; Greenberg , Barry H.; Levy , Phillip D.; Masip, Josep; Metra, Marco; Pang , Peter S.; Ponikowski , Piotr; Severin , Thomas M.; Teerlink, John R.; Teichman, Sam L.; Voors, Adriaan A.; Werdan, Karl; Cotter, Gad; Emergency Medicine, School of MedicinePrevious studies have suggested that the neutrophil-to-lymphocyte ratio (NLR) is a novel yet readily evaluable inflammatory biomarker that may be useful for determining cardiovascular prognosis during acute episodes. The study investigated the role of NLR in predicting cardiovascular (CV) outcomes in patients with acute heart failure (HF). Individual patient data from the BLAST-AHF (phase 2b study of the biased ligand of the angiotensin 2 type 1 receptor, TRV027), Pre-RELAX-AHF (phase 2b study of recombinant human relaxin-2, serelaxin), and RELAX-AHF (phase 3 study of serelaxin) randomized, placebo-controlled studies for patients with acute HF were pooled for analysis. Dyspnea visual analog scale area under the curve through day 5, worsening HF through day 5, 30-day all-cause mortality, 60-day HF/renal failure rehospitalizations or CV death, 180-day all-cause mortality, and 180-day CV death were assessed. There were several differences in the baseline characteristics of the patients divided by NLR tertile, with patients in the higher NLR having worse clinical characteristics. NLR was an independent predictor of 30-day all-cause mortality (adjusted hazard ratio [HR] per log2 NLR increment: 1.66 [1.22 to 2.25], p = 0.001), 60-day HF/renal failure rehospitalizations or CV death: 1.33 [1.12 to 1.57], p = 0.001), 180-day all-cause mortality (adjusted HR 1.27 [1.08 to 1.50], p = 0.003), and 180-day CV death (adjusted HR 1.24 [1.04 to 1.49], p = 0.018). NLR, a readily available inflammatory biomarker, was associated with independent risk for short- and long-term adverse outcomes in acute HF, surpassing traditional markers, such as natriuretic peptides.Item Optimization of Evidence-Based Heart Failure Medications After an Acute Heart Failure Admission: A Secondary Analysis of the STRONG-HF Randomized Clinical Trial(American Medical Association, 2024) Cotter, Gad; Deniau, Benjamin; Davison, Beth; Edwards, Christopher; Adamo, Marianna; Arrigo, Mattia; Barros, Marianela; Biegus, Jan; Celutkiene, Jelena; Cerlinskaite-Bajore, Kamile; Chioncel, Ovidiu; Cohen-Solal, Alain; Damasceno, Albertino; Diaz, Rafael; Filippatos, Gerasimos; Gayat, Etienne; Kimmoun, Antoine; Lam, Carolyn S. P.; Metra, Marco; Novosadova, Maria; Pang, Peter S.; Pagnesi, Matteo; Ponikowski, Piotr; Saidu, Hadiza; Sliwa, Karen; Takagi, Koji; Ter Maaten, Jozine M.; Tomasoni, Daniela; Voors, Adriaan; Mebazaa, Alexandre; Emergency Medicine, School of MedicineImportance: The Safety, Tolerability, and Efficacy of Rapid Optimization, Helped by N-Terminal Pro-Brain Natriuretic Peptide Testing of Heart Failure Therapies (STRONG-HF) trial strived for rapid uptitration aiming to reach 100% optimal doses of guideline-directed medical therapy (GDMT) within 2 weeks after discharge from an acute heart failure (AHF) admission. Objective: To assess the association between degree of GDMT doses achieved in high-intensity care and outcomes. Design, setting, and participants: This was a post hoc secondary analysis of the STRONG-HF randomized clinical trial, conducted from May 2018 to September 2022. Included in the study were patients with AHF who were not treated with optimal doses of GDMT before and after discharge from an AHF admission. Data were analyzed from January to October 2023. Interventions: The mean percentage of the doses of 3 classes of HF medications (renin-angiotensin system inhibitors, β-blockers, and mineralocorticoid receptor antagonists) relative to their optimal doses was computed. Patients were classified into 3 dose categories: low (<50%), medium (≥50% to <90%), and high (≥90%). Dose and dose group were included as a time-dependent covariate in Cox regression models, which were used to test whether outcomes differed by dose. Main outcome measures: Post hoc secondary analyses of postdischarge 180-day HF readmission or death and 90-day change in quality of life. Results: A total of 515 patients (mean [SD] age, 62.7 [13.4] years; 311 male [60.4%]) assigned high-intensity care were included in this analysis. At 2 weeks, 39 patients (7.6%) achieved low doses, 254 patients (49.3%) achieved medium doses, and 222 patients (43.1%) achieved high doses. Patients with lower blood pressure and more congestion were less likely to be uptitrated to optimal GDMT doses at week 2. As a continuous time-dependent covariate, an increase of 10% in the average percentage optimal dose was associated with a reduction in 180-day HF readmission or all-cause death (primary end point: adjusted hazard ratio [aHR], 0.89; 95% CI, 0.81-0.98; P = .01) and a decrease in 180-day all-cause mortality (aHR, 0.84; 95% CI, 0.73-0.95; P = .007). Quality of life at 90 days, measured by the EQ-5D visual analog scale, improved more in patients treated with higher doses of GDMT (mean difference, 0.10; 95% CI, -4.88 to 5.07 and 3.13; 95% CI, -1.98 to 8.24 points in the medium- and high-dose groups relative to the low-dose group, respectively; P = .07). Adverse events to day 90 occurred less frequently in participants with HIC who were prescribed higher GDMT doses at week 2. Conclusions and relevance: Results of this post hoc analysis of the STRONG-HF randomized clinical trial show that, among patients randomly assigned to high-intensity care, achieving higher doses of HF GDMT 2 weeks after discharge was feasible and safe in most patients.
