Abstract
BACKGROUND Tricuspid regurgitation (TR) is common and is associated with poor outcomes in patients with heart failure (HF). However, data with adjudicated events from fully characterized patients with heart failure with reduced ejection fraction (HFrEF) are lacking. OBJECTIVES This study sought to explore the association between mild or moderate/severe TR and clinical outcomes of patients with HFrEF. METHODS GALACTIC-HF (Global Approach to Lowering Adverse Cardiac Outcomes Through Improving Contractility in Heart Failure) was a double-blind, placebo-controlled randomized trial comparing omecamtiv mecarbil vs placebo in patients with symptomatic HFrEF. RESULTS Among the 8,232 patients analyzed in the GALACTIC-HF trial, 8,180 (99%) had data regarding baseline TR (none: n = 6,476 [79%], mild: n = 919 [11%], and moderate/severe: n = 785 [10%]). The primary composite outcome of a first HF event or cardiovascular death occurred in 2,368 (36.6%) patients with no TR, 353 (38.4%) patients with mild TR, and 389 (49.6%) patients with moderate/severe TR. Moderate/severe TR was independently associated with a higher relative risk of the primary composite outcome compared with either no TR (adjusted HR: 1.12 [95% CI: 1.01-1.26]; P = 0.046) or no/mild TR (adjusted HR: 1.14 [95% CI: 1.02-1.27]; P = 0.025) driven predominantly by HF events. The association between moderate/severe TR and clinical outcomes was more pronounced in outpatients with worse renal function, higher left ventricular ejection fraction, and lower N-terminal pro-B-type natriuretic peptide and bilirubin levels. The beneficial treatment effect of omecamtiv mecarbil vs placebo on clinical outcomes was not modified by TR. CONCLUSIONS In symptomatic patients with HFrEF, baseline moderate/severe TR was independently associated with cardiovascular death or HF events driven predominantly by HF events. The beneficial treatment effect of omecamtiv mecarbil on the primary outcome was not modified by TR.

Abstract
BACKGROUND Omecamtiv mecarbil improves outcomes in patients with heart failure and reduced ejection fraction (HFrEF). We examined the relationship between baseline troponin levels, change in troponin levels over time and the treatment effect of omecamtiv mecarbil in patients enrolled in the Global Approach to Lowering Adverse Cardiac Outcomes through Improving Contractility in Heart Failure (GALACTIC-HF) trial (NCT02929329). METHODS GALACTIC-HF was a double-blind, placebo-controlled trial that randomized 8256 patients with symptomatic HFrEF to omecamtiv mecarbil or placebo. High-sensitivity troponin I (cTnI) was measured serially at a core laboratory. We analyzed the relationship between both baseline cTnI and change in cTnI concentrations with clinical outcomes and the treatment effect of omecamtiv mecarbil. RESULTS Higher baseline cTnI concentrations were associated with a risk of adverse outcomes (hazard ratio for the primary endpoint of time to first HF event or CV death = 1.30; 95% CI 1.28, 1.33; P < 0.001 per doubling of baseline cTnI). Although the incidence of safety outcomes was higher in patients with higher baseline cTnI, there was no difference between treatment groups. Treatment with omecamtiv mecarbil led to a modest increase in cTnI that was related to plasma concentrations of omecamtiv mecarbil, and it peaked at 6 weeks. An increase in troponin from baseline to week 6 was associated with an increased risk of the primary endpoint (P < 0.001), which was similar, regardless of treatment assignment (P value for interaction = 0.2). CONCLUSIONS In a cohort of patients with HFrEF, baseline cTnI concentrations were strongly associated with adverse clinical outcomes. Although cTnI concentrations were higher in patients treated with omecamtiv mecarbil, we did not find a differential effect of omecamtiv mecarbil on either safety or efficacy based on baseline cTnI status or change in cTnI.

Abstract
Background Many patients with heart failure (HF) have severely reduced ejection fraction but do not meet threshold for consideration of advanced therapies (ie, stage D HF). The clinical profile and health care costs associated with these patients in US practice is not well described. Methods and Results We examined patients hospitalized for worsening chronic heart failure with reduced ejection fraction ≤40% from 2014 to 2019 in the GWTG-HF (Get With The Guidelines-Heart Failure) registry, who did not receive advanced HF therapies or have end-stage kidney disease. Patients with severely reduced EF defined as EF ≤30% were compared with those with EF 31% to 40% in terms of clinical profile and guideline-directed medical therapy. Among Medicare beneficiaries, postdischarge outcomes and health care expenditure were compared. Among 113 348 patients with EF ≤40%, 69% (78 589) had an EF ≤30%. Patients with severely reduced EF ≤30% tended to be younger and were more likely to be Black. Patients with EF ≤30% also tended to have fewer comorbidities and were more likely to be prescribed guideline-directed medical therapy ("triple therapy" 28.3% versus 18.2%, P<0.001). At 12-months postdischarge, patients with EF ≤30% had significantly higher risk of death (HR, 1.13 [95% CI, 1.08-1.18]) and HF hospitalization (HR, 1.14 [95% CI, 1.09-1.19]), with similar risk of all-cause hospitalizations. Health care expenditures were numerically higher for patients with EF ≤30% (median US$22 648 versus $21 392, P=0.11). Conclusions Among patients hospitalized for worsening chronic heart failure with reduced ejection fraction in US clinical practice, most patients have severely reduced EF ≤30%. Despite younger age and modestly higher use of guideline-directed medical therapy at discharge, patients with severely reduced EF face heightened postdischarge risk of death and HF hospitalization.

Abstract
IMPORTANCE Exercise limitation is a cardinal manifestation of heart failure with reduced ejection fraction (HFrEF) but is not consistently improved by any of the current guideline-directed medical therapies. OBJECTIVE To determine whether omecamtiv mecarbil, a novel direct myosin activator that improves cardiac performance and reduces the risk for cardiovascular death or first HF event in HFrEF, can improve peak exercise capacity in patients with chronic HFrEF. DESIGN, SETTING, AND PARTICIPANTS Phase 3, double-blind, placebo-controlled randomized trial of patients with HFrEF (left ventricular ejection fraction ≤35%), New York Heart Association class II-III symptoms, N-terminal pro-B-type natriuretic peptide level of 200 pg/mL or greater, and baseline peak oxygen uptake (V̇o2) of 75% or less of predicted. Patients were randomized in a 2:1 ratio (omecamtiv mecarbil to placebo) between March 2019 and May 2021 at 63 sites in North America and Europe, with the last patient visit occurring on November 29, 2021. INTERVENTIONS Omecamtiv mecarbil (n = 185) or matching placebo (n = 91), given orally twice daily at a dose of 25 mg, 37.5 mg, or 50 mg based on target plasma levels, for 20 weeks. MAIN OUTCOMES AND MEASURES The primary end point was a change in exercise capacity (peak V̇o2) from baseline to week 20. Secondary end points included total workload, ventilatory efficiency, and daily physical activity as determined by accelerometry. RESULTS Among 276 patients who were randomized (median age, 64 years; IQR, 55-70 years; 42 women [15%]), 249 (90%) completed the trial. The median left ventricular ejection fraction was 28% (IQR, 21-33) and the median baseline peak V̇o2 was 14.2 mL/kg/min (IQR, 11.6-17.4) in the omecamtiv mecarbil group and 15.0 mL/kg/min (IQR, 12.0-17.2) in the placebo group. Mean change in peak V̇o2 did not differ significantly between the omecamtiv mecarbil and placebo groups (mean, -0.24 mL/kg/min vs 0.21 mL/kg/min; least square mean difference, -0.45 mL/kg/min [95% CI, -1.02 to 0.13]; P = .13). Adverse events included dizziness (omecamtiv mecarbil: 4.9%, placebo: 5.5%), fatigue (omecamtiv mecarbil: 4.9%, placebo: 4.4%), heart failure events (omecamtiv mecarbil: 4.9%, placebo: 4.4%), death (omecamtiv mecarbil: 1.6%, placebo: 1.1%), stroke (omecamtiv mecarbil: 0.5%, placebo: 1.1%), and myocardial infarction (omecamtiv mecarbil: 0%, placebo: 1.1%). CONCLUSIONS AND RELEVANCE In patients with chronic HFrEF, omecamtiv mecarbil did not significantly improve exercise capacity over 20 weeks compared with placebo. These findings do not support the use of omecamtiv mecarbil for treatment of HFrEF for improvement of exercise capacity. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT03759392.

Abstract
A 48-year-old woman with a past medical history of migraines and hyperlipidemia presented due to severe retrosternal chest pain with no other associated signs or symptoms. The patient was hemodynamically stable and was found to have an elevated troponin with electrocardiogram showing no ischemic changes. Computed tomography of the coronary arteries showed a left dominant system with dissection extending from the mid-to-distal left anterior descending (LAD) artery. The patient was subsequently discharged on medical therapy but returned 3 days later due to worsening chest pain. Electrocardiogram revealed inferior and anteroseptal ST segment changes with peak troponin of 14.9 ng/ml (reference range <0.80 ng/ml). Coronavirus disease 2019 (COVID-19) nasopharyngeal swab was performed prior to urgent coronary angiogram. Coronary angiogram was performed with full personal protective equipment for respiratory and droplet precautions due to pending COVID-19 testing results. Angiogram revealed spontaneous coronary artery dissection (SCAD) extending from the ostium of the LAD to the distal vessel. COVID-19 testing returned positive while in intensive care unit. The patient was not a percutaneous coronary intervention candidate due to the extent of the dissection and was not a surgical candidate due to a lack of graftable target and medical management was continued. To our knowledge, this case is the first in which SCAD has been reported in the LAD in a patient with COVID-19 with no other symptoms of respiratory illness or symptoms classically associated with the novel coronavirus. SCAD should be considered on the differential as one of the various cardiac manifestations of COVID-19 infection.

Abstract
BACKGROUND Recently, the symptom of bendopnea, that is, shortness of breath when bending forwards such as when putting on shoes, has been described in heart failure patients and found to be associated with higher ventricular filling pressures, particularly in the setting of low cardiac index. However, it is not known whether bendopnea is associated with clinical outcomes. METHODS In a prospective convenience sample of 179 patients followed in our heart failure disease management clinic, we determined the presence of bendopnea at the time of enrollment and ascertained clinical outcomes through 1 year of follow-up. We performed univariate and stepwise multivariable modeling to test the association of bendopnea with clinical outcomes. RESULTS Bendopnea was present in 32 of 179 (18%) subjects. At 1 year, those with versus without bendopnea were at increased risk of the composite endpoint of death, heart failure admission, inotrope initiation, left ventricular assist device implantation, or cardiac transplantation in univariate (hazard ratio [HR] 1.9, P < .05) but not multivariable (HR 1.9, P = .11) analysis. Bendopnea was more strongly associated with short-term outcomes including heart failure admission at 3 months in both univariate (HR 3.1, P < .004) and multivariable (HR 2.5, P = .04) analysis. CONCLUSIONS Bendopnea was associated with an increased risk of adverse outcomes in ambulatory patients with heart failure, particularly heart failure admission at 3 months.
