Aims: The VICTORIA trial demonstrated a significant reduction in the primary composite outcome of heart failure (HF) hospitalization or cardiovascular death with vericiguat relative to placebo in high-risk HF. This study aimed to contextualize treatment effects of vericiguat in populations with varying risk profiles simulated from the PARADIGM-HF and DAPA-HF trials., Methods: Subgroups of VICTORIA participants (n = 5050) were generated to simulate PARADIGM-HF and DAPA-HF trial populations. The PARADIGM-HF-eligible population excluded participants not meeting left ventricular ejection fraction (LVEF), estimated glomerular filtration rate (eGFR), and minimal dose criteria and those with high predicted probability of run-in failure. The DAPA-HF-eligible population excluded those not meeting LVEF and eGFR criteria or with recent (<30 days) HF hospitalization. The time-to-first-event analysis was performed using an unadjusted Cox proportional hazards model., Results: A total of 1982 (39.2%) and 2543 (50.4%) VICTORIA participants were respectively deemed eligible for PARADIGM-HF and DAPA-HF. Vericiguat was associated with numerically larger reductions in the primary outcome of HF hospitalization or cardiovascular death in populations simulated from PARADIGM-HF [hazard ratio (HR) 0.85, 95% confidence interval (CI) 0.72-0.99] and DAPA-HF (HR 0.82, 95% CI 0.71-0.94) compared with the overall VICTORIA trial (HR 0.90). Significant reduction in HF hospitalization with vericiguat was also observed in the DAPA-HF-eligible population (HR 0.83, 95%CI 0.73-0.95) and with a nominal reduction in the PARADIGM-HF-eligible population (HR 0.86, 95% CI 0.74-1.01)., Conclusions: A trend towards enhanced efficacy of vericiguat in populations simulated from PARADIGM-HF and DAPA-HF was observed. These findings support further exploration of vericiguat in lower-risk HF populations as is being investigated in the ongoing VICTOR (a study of vericiguat in participants with chronic heart failure with reduced ejection fraction) trial., (© 2024 The Author(s).

Background: Type 2 diabetes mellitus (T2DM) significantly worsens heart failure (HF) prognosis., Objectives: This study sought to investigate the impact of T2DM on outcomes in patients enrolled in VICTORIA and assess the efficacy of vericiguat in patients with and without T2DM., Methods: Patients with HF with reduced ejection fraction were randomized to receive vericiguat or placebo in addition to standard therapy. The primary outcome was a composite of cardiovascular death or first heart failure hospitalization (HFH). A Cox proportional hazards model was used to calculate HRs and 95% CIs to assess if the effect of vericiguat differed by history of T2DM., Results: Of 5,050 patients enrolled, 3,683 (72.9%) had glycosylated hemoglobin (HbA 1c ) measured at baseline. Of these, 2,270 (61.6%) had T2DM, 741 (20.1%) had pre-T2DM, 449 (12.2%) did not have T2DM, and 178 (4.8%) had undiagnosed T2DM. The risks of the primary outcome, HFH, and all-cause and cardiovascular mortality were high across all categories. The efficacy of vericiguat on the primary outcome did not differ in patients stratified by T2DM by history (HR: 0.92; 95% CI: 0.81-1.04), T2DM measured by HbA 1c (HR: 0.77; 95% CI: 0.49-1.20), and pre-T2DM measured by HbA 1c (HR: 0.88; 95% CI: 0.68-1.13) and in those with normoglycemia (HR: 1.02: 95% CI: 0.75-1.39; P for interaction = 0.752). No significant differences were observed in subgroups with respect to the efficacy of vericiguat on HFH and all-cause or cardiovascular death., Conclusions: In this post hoc analysis of VICTORIA, vericiguat compared with placebo significantly reduced the risk of cardiovascular death or HFH in patients with worsening HF with reduced ejection fraction regardless of T2DM status.

Background: In VICTORIA (Vericiguat Global Study in Subjects with Heart Failure with Reduced Ejection Fraction), participants with heart failure (HF) and reduced ejection fraction, vericiguat decreased the primary composite outcome (time to first HF hospitalization [HFH] or cardiovascular death [CVD]) (897 events) compared with placebo (972 events) (hazard ratio, 0.90; 95% confidence interval [CI], 0.82-0.98; P = .02). In this prespecified secondary analysis, we applied the weighted composite end point (WCE) and the win ratio (WR) methods to provide complementary assessments of treatment effect., Methods and Results: The WCE method estimated the mean HFH-adjusted survival based on prespecified weights from a Delphi panel of the VICTORIA executive committee and national leaders: mild (weight per event, 0.39), moderate (0.5), or severe (0.67) HFH, and CVD (1.0). The unmatched WR was estimated for the descending hierarchy of CVD, then recurrent HFH. The WCE used all 3412 primary clinical events: 875 severe HFH (vericiguat, 416/ placebo, 459), 1614 moderate HFH (767/847), 68 mild HFH (38/30), and 855 CVD (414/441). Improved HFH-adjusted survival occurred with vericiguat (mean 78.2% vs 75.6%, difference 2.4%, 95% CI, 1.7%-3.2%, P < .0001). Based on a comparison of 6,375,624 pairs, the WR of 1.13 (95% CI 1.03-1.24, P = .01) also indicated improved clinical outcomes with vericiguat., Conclusions: The results of the WCE and WR methods were consistent with the primary analysis of the time to first HFH or CVD. Although both WCE and WR assessed recurrent events, the WCE allowed inclusion of all recurrent events, insights on the severity of HFH events, and an absolute measure of the participant-treatment experience.

Background: Heart failure with preserved ejection fraction (HFpEF) is a heterogeneous syndrome that may emerge from overlapping systemic processes associated with comorbidities. We assessed whether unique clusters of circulating proteins are associated with specific clinical characteristics and functional status at baseline and follow-up in a well-phenotyped cohort of patients with HFpEF., Methods: We evaluated 368 proteins associated with cardiovascular disease and inflammation in prerandomization blood samples from 763 VITALITY-HFpEF (Vericiguat to Improve Physical Functioning in Daily Living Activities of Patients With HFpEF) participants who had a left ventricular ejection fraction ≥45% and a heart failure decompensation event within 6 months. Proteins were clustered, and their associations with clinical characteristics, baseline, and 24-week functional outcomes (Kansas City Cardiomyopathy Questionnaire Physical Limitation Score, 6-minute walk distance [6MWD], and Fried frailty phenotype) were estimated with linear regression. Elastic net regression was used to derive a proteomic summary composite to predict changes in 24-week functional outcomes., Results: Four unique protein clusters were identified, containing 24, 66, 197, and 81 proteins. At baseline, 2 protein clusters with the hub proteins caspase-3 and Dickkopf-related protein 1 were associated with increased frailty, whereas the cluster with tumor necrosis factor receptor 1 as a hub protein was associated with lower Kansas City Cardiomyopathy Questionnaire Physical Limitation Score and shorter 6MWD. By contrast, the cluster with protein C as a hub protein was associated with less frailty and longer a 6MWD. The 24-week increase in 6MWD was negatively correlated with the protein cluster with caspase-3; the protein C cluster was correlated with less frailty at 24 weeks. The baseline proteomic summary composite predicted observed changes in Kansas City Cardiomyopathy Questionnaire Physical Limitation Score and 6MWD at 24 weeks (r=0.42 and 0.30; P <0.001 for both)., Conclusions: Proteomics differentiate specific baseline functional traits associated with HFpEF and may facilitate phenotyping in a heterogeneous disease. These proteins also provide insights into the diverse pathophysiology of HFpEF and which patients may improve functional status during follow-up., Registration: URL: https://www.clinicaltrials.gov; Unique identifier: NCT03547583., Competing Interests: Dr deFilippi has received research funding to Inova from Abbott Diagnostics, Roche Diagnostics, Siemens Healthineers, and Ortho Diagnostics and consults for FujiRebio, Roche Diagnostics, Siemens Healthineers, and Ortho Diagnostics.

Aims: Reverse ventricular remodelling, defined as a decrease in left ventricular end-systolic volume indexed to body surface area (LVESVI) or an increase in left ventricular ejection fraction (LVEF), is associated with improved clinical outcomes in patients with heart failure with reduced ejection fraction (HFrEF). However, the underlying pathophysiological mechanisms remain unclear., Methods and Results: We evaluated paired core-lab assessed echocardiograms and measurements of 92 biomarkers at baseline and 8 months thereafter in 419 participants with HFrEF. Reverse ventricular remodelling was defined as a >5% LVEF increase or >15% LVESVI relative decrease between baseline and 8 months. We evaluated the association between baseline biomarkers and their changes with reverse ventricular remodelling in the prospectively randomized controlled VICTORIA (Vericiguat Global Study in Subjects With Heart Failure With Reduced Ejection Fraction) trial. Of 419 patients (median age 66 [interquartile range 57-74] years, 27.4% women), 206 (49.2%) had reverse ventricular remodelling (either a 5% LVEF increase or a 15% LVESVI decrease). There were no differences in baseline biomarker concentrations between patients with versus those without reverse ventricular remodelling on follow-up. However, in patients with reverse ventricular remodelling there were significant decreases in biomarkers relating to inflammation and cardiac metabolism; particularly the tumour necrosis factor superfamily member 13B (ratio 0.82, 95% confidence interval [CI] 0.77-0.88), growth differentiation factor-15 (ratio 0.74, 95% CI 0.66-0.84), and insulin-like growth factor binding protein 7 (ratio 0.80, 95% CI 0.73-0.88)., Conclusions: Reverse ventricular remodelling in patients with HFrEF is associated with a decrease of biomarkers related to inflammation and cardiac metabolism., (© 2024 The Author(s).

Background: In VICTORIA (Vericiguat Global Study in Subjects With Heart Failure With Reduced Ejection Fraction), vericiguat compared with placebo reduced cardiovascular death or heart failure (HF) hospitalization in patients with HF with reduced ejection fraction., Objectives: This study explored the association between vericiguat and recurrent hospitalizations and subsequent mortality after HF hospitalization., Methods: The treatment effect of vericiguat on the burden of HF hospitalizations was evaluated by assessing total HF hospitalization and cardiovascular death in the overall trial and based on baseline N-terminal pro-B-type natriuretic peptide levels with and without adjustment for VICTORIA model covariates (ie, baseline variables associated with the primary endpoint) assessed via the Andersen-Gill method. Associations between vericiguat and recurrent hospitalization and mortality adjusted for VICTORIA model covariates are reported., Results: There were 1,222 total HF hospitalizations and cardiovascular deaths among 2,526 patients in the vericiguat group and 1,336 total events among 2,524 patients in the placebo group (unadjusted HR: 0.89 [95% CI: 0.81-0.97] and adjusted HR: 0.92 [95% CI: 0.84-1.01]). In the subgroup with N-terminal pro-B-type natriuretic peptide levels ≤2,816 pg/mL (ie, Q1 and Q2; median or below), there was a suggestion of a benefit with vericiguat (adjusted HRs of 0.80 [95% CI: 0.64-1.01] and 0.77 [95% CI: 0.62-0.94], respectively) compared with those above this value (adjusted HRs of 1.12 [95% CI: 0.93-1.34] and 0.87 [95% CI: 0.74-1.04] for Q3 and Q4). There was no significant difference in treatment effect between patients with vs without an HF hospitalization. After HF hospitalization, the all-cause mortality rate (events per 100 patient-years) was 48.6 for vericiguat and 44.1 for placebo., Conclusions: Additional investigation of the association between vericiguat and cardiovascular death and total HF hospitalizations by recurrent event analysis did not show a statistically significant reduction in events. Mortality was high after HF hospitalization, emphasizing the need for further therapies to reduce morbidity and mortality.

Aims: In VICTORIA, vericiguat compared with placebo reduced the risk of cardiovascular death (CVD) and heart failure hospitalization (HFH) in patients enrolled after a worsening heart failure (WHF) event. We examined clinical outcomes and efficacy of vericiguat as it relates to background use of loop diuretics in patients with WHF., Methods and Results: We calculated the total daily loop diuretic dose equivalent to furosemide dosing at randomization and categorized these as: no loop diuretic, 1-39, 41-80, 40, and >80 mg total daily dose (TDD). The primary composite outcome of CVD/HFH and its components were evaluated based on TDD loop diuretic and expressed as adjusted hazard ratios with 95% confidence intervals. Post-randomization rates of change in TDD were also examined. Of 4974 patients (98% of the trial) with diuretic dose information available at randomization, 540 (10.8%) were on no loop diuretic, 647 (13.0%) were on 1-39, 1633 (32.8%) were on 40, 1185 (23.8%) were on 41-80, and 969 (19.4%) were on >80 mg TDD. Patients with higher TDD had a higher rate of primary and secondary clinical outcomes. There were no significant interactions with TDD at randomization and efficacy of vericiguat versus placebo for any outcome (all p interaction  > 0.5). Post-randomization diuretic dose changes for vericiguat and placebo showed similar rates of up-titration (19.6 and 20.2/100 person-years), down-titration (16.8 and 18.1/100 person-years), and stopping diuretics (22.9 and 24.2/100 person-years)., Conclusions: Loop diuretic TDD at randomization was independently associated with worse outcomes in this high-risk population. The efficacy of vericiguat was consistent across the range of diuretic doses., (© 2024 European Society of Cardiology.)

Aims: The relationship between accelerometry data and changes in Kansas City Cardiomyopathy Questionnaire-Physical Limitation Score (KCCQ-PLS) or 6 min walk test (6MWT) is not well understood., Methods and Results: VITALITY-HFpEF accelerometry substudy (n = 69) data were assessed at baseline and 24 weeks. Ordinal logistic regression models were used to assess the association between accelerometry activity and deterioration, improved, or unchanged KCCQ-PLS (≥8.33 and ≤ -4.17 points) and 6MWT (≥32 vs. ≤ -32 m). KCCQ-PLS score deteriorated in 16 patients, improved in 34, and was unchanged in 19. 6MWT deteriorated in 8 patients, improved in 21, and was unchanged in 19. Mean accelerometer wear was 21.4 (±2.1) h/day. Changes in hours active from baseline to 24 weeks were not significantly different among patients who exhibited deterioration, improvement, or no change in KCCQ-PLS [odds ratio (OR) 0.91, 95% confidence interval (CI) 0.71-1.18; P = 0.48] or 6MWT (OR 1.21, 95% CI 0.91-1.60; P = 0.18). Similar lack of association was observed for other accelerometry metrics and change in KCCQ and 6MWT. These findings were unaffected when KCCQ and 6MWT were examined as continuous variables., Conclusions: Accelerometer-based activity measures did not correlate with subjective or objective standard measures of health status and functional capacity in heart failure with preserved ejection fraction. Further investigation of their relationships to clinical outcomes is required., (© 2023 The Authors.

Background: The VICTORIA trial (Vericiguat Global Study in Subjects With Heart Failure With Reduced Ejection Fraction) demonstrated that, in patients with high-risk heart failure, vericiguat reduced the primary composite outcome of cardiovascular death or heart failure hospitalization relative to placebo. The hazard ratio for all-cause mortality was 0.95 (95% CI, 0.84-1.07). In a prespecified analysis, treatment effects varied substantially as a function of baseline NT-proBNP (N-terminal pro-B-type natriuretic peptide) levels, with survival benefit for vericiguat in the lower NT-proBNP quartiles (hazard ratio, 0.82 [95% CI, 0.69-0.97]) and no benefit in the highest NT-proBNP quartile (hazard ratio, 1.14 [95% CI, 0.95-1.38]). An economic analysis was a major secondary objective of the VICTORIA research program., Methods: Medical resource use data were collected for all VICTORIA patients (N=5050). Costs were estimated by applying externally derived US cost weights to resource use counts. Life expectancy was projected from patient-level empirical trial survival results with the use of age-based survival modeling methods. Quality-of-life adjustments were based on prospectively collected EQ-5D-based utilities. The primary outcome was the incremental cost-effectiveness ratio, comparing vericiguat with placebo, assessed from the US health care sector perspective over a lifetime horizon. Cost-effectiveness was estimated using the total VICTORIA cohort, both with and without interaction between treatment and baseline NT-proBNP., Results: Life expectancy modeling results varied according to whether the observed heterogeneity of treatment effect by baseline NT-proBNP values was incorporated into the modeling. Including the interaction term, the vericiguat arm had an estimated quality-adjusted life expectancy of 4.56 quality-adjusted life-years (QALYs) compared with 4.13 QALYs for placebo (incremental discounted QALY, 0.43). Without the treatment heterogeneity/interaction term, vericiguat had 4.50 QALYs compared with 4.33 QALYs for placebo (incremental discounted QALY, 0.17). Incremental discounted costs (vericiguat minus placebo) were $28 546 with the treatment interaction and $20 948 without it. Corresponding incremental cost-effectiveness ratios were $66 509 per QALY allowing for treatment heterogeneity and $124 512 without heterogeneity., Conclusions: Vericiguat use in the VICTORIA trial met criteria for intermediate value, but the incremental cost-effectiveness ratio estimates were sensitive to whether the analysis accounted for observed NT-proBNP treatment effect heterogeneity. The cost-effectiveness of vericiguat was driven by the projected incremental life expectancy among patients in the lowest 3 quartiles of NT-proBNP., Registration: URL: https://www., Clinicaltrials: gov; Unique identifier: NCT02861534., Competing Interests: Disclosures Dr Cowper reports research grant support from Merck, Eli Lilly, Novartis, AstraZeneca, Bristol Myers Squibb, AGA Medical, Tenax Therapeutics, GE Healthcare, Mayo Clinic, and Gilead.

Aims: Whether electrocardiographic (ECG) measurements predict mortality in chronic heart failure with reduced ejection fraction (HFrEF) is unknown., Methods and Results: We studied 4880 patients from the Vericiguat Global Study in Subjects with Heart Failure with Reduced Ejection Fraction (VICTORIA) trial with a baseline 12-lead ECG. Associations between ECG measurements and mortality were estimated as hazard ratios (HR) and adjusted for the Meta-Analysis Global Group in Chronic Heart Failure (MAGGIC) risk score, N-terminal pro-B-type natriuretic peptide, and index event. Select interactions between ECG measurements, patient characteristics and mortality were examined. Over a median of 10.8 months, there were 824 cardiovascular (CV) deaths (214 sudden) and 1005 all-cause deaths. Median age was 68 years (interquartile range [IQR] 60-76), 24% were women, median ejection fraction was 30% (IQR 23-35), 41% had New York Heart Association class III/IV, and median MAGGIC score was 24 (IQR 19-28). After multivariable adjustment, significant associations existed between heart rate (per 5 bpm: HR 1.02), QRS duration (per 10 ms: HR 1.02), absence of left ventricular hypertrophy (HR 0.64) and CV death, and similarly so with all-cause death (HR 1.02; HR 1.02; HR 0.61, respectively). Contiguous pathologic Q waves were significantly associated with sudden death (HR 1.46), and right ventricular hypertrophy with all-cause death (HR 1.44). The only sex-based interaction observed was for pathologic Q waves on CV (men: HR 1.05; women: HR 1.64, p interaction  = 0.024) and all-cause death (men: HR 0.99; women: HR 1.57; p interaction  = 0.010). Whereas sudden death doubled in females, it did not differ among males (male: HR 1.25, 95% confidence interval [CI] 0.87-1.79; female: HR 2.50, 95% CI 1.23-5.06; p interaction  = 0.141)., Conclusion: Routine ECG measurements provide additional prognostication of mortality in high-risk HFrEF patients, particularly in women with contiguous pathologic Q waves., (© 2023 The Authors.

Background: Selecting high-risk patients with heart failure with potentially modifiable cardiovascular events is a priority. Our objective was to evaluate NT-proBNP (N-terminal pro-B-type natriuretic peptide) changes during a 30-day screening to establish (1) the frequency and direction of changes; (2) whether a relationship exists between changes in NT-proBNP and the primary composite outcome of cardiovascular death and heart failure hospitalization; and (3) whether changes in NT-proBNP relate to vericiguat's clinical benefit., Methods: VICTORIA (A Study of Vericiguat in Participants With Heart Failure With Reduced Ejection Fraction) randomized 5050 patients with heart failure with reduced ejection fraction and a recent worsening heart failure event. We studied 3821 patients who had NT-proBNP measured during screening and at randomization., Results: Sixteen hundred exhibited a >20% reduction, 1412 had ≤20% change, and 809 showed a >20% rise in NT-proBNP levels. As compared with the primary composite outcome of 28.4/100 patient-years (497 events; 31.1%) in patients with a >20% decline in NT-proBNP, those with >20% during screening had worse outcomes; 48.8/100 patient-years (359 events; 44.4%); adjusted hazard ratio, 1.61 (95% CI, 1.39-1.85). Those patients with a ≤20% change in NT-proBNP had intermediate outcomes; 39.2/100 patient-years (564 events; 39.9%); adjusted hazard ratio, 1.33 (95% CI, 1.17-1.51). No relationship existed between NT-proBNP changes during screening and vericiguat's effect on cardiovascular death and heart failure hospitalization., Conclusions: Substantial differences occurred in the rates of cardiovascular death and heart failure hospitalization, especially in patients with a >20% change in NT-proBNP levels during screening interval. Sequential NT-proBNP levels add important prognostic information meriting consideration in future heart failure trials., Registration: URL: https://www., Clinicaltrials: gov; Unique identifier: NCT02861534., Competing Interests: Disclosures Dr Armstrong received research grants from Merck, Bayer, Boehringer Ingelheim/Eli Lilly, and CSL Limited; and consulting fees from Merck, Bayer, Boehringer Ingelheim, and Novo Nordisk.

Background: We examined whether the primary composite outcome (cardiovascular death or heart failure hospitalization) was related to differences in background use and dosing of guideline-directed medical therapy in patients with heart failure with reduced ejection fraction enrolled in VICTORIA (Vericiguat Global Study in Subjects with Heart Failure with Reduced Ejection Fraction), a randomized trial of vericiguat versus placebo., Methods: We evaluated the adherence to guideline use of angiotensin-converting enzyme inhibitors, angiotensin-receptor blockers, angiotensin receptor-neprilysin inhibitors, beta-blockers, and mineralocorticoid receptor antagonists. We assessed basic adherence; indication-corrected adherence accounting for guideline indications and contraindications; and dose-corrected adherence (indication-corrected adherence+≥50% of drug dose target). Associations between study treatment and the primary composite outcome according to the adherence to guidelines were assessed using multivariable adjustment; adjusted hazard ratios with 95% CIs and P interaction are reported., Results: Of 5050 patients, 5040 (99.8%) had medication data at baseline. For angiotensin-converting enzyme inhibitor, angiotensin-receptor blockers, and angiotensin receptor-neprilysin inhibitors, basic adherence to guidelines was 87.4%, indication-corrected was 95.7%, and dose-corrected was 50.9%. For beta-blockers, basic adherence was 93.1%, indication-corrected was 96.2%, and dose-corrected was 45.4%. For mineralocorticoid receptor antagonists, basic adherence was 70.3%, indication-corrected was 87.1%, and dose-corrected was 82.2%. For triple therapy (angiotensin-converting enzyme inhibitors, angiotensin-receptor blockers, or angiotensin receptor-neprilysin inhibitors+beta-blocker+mineralocorticoid receptor antagonist), basic adherence was 59.7%, indication-corrected was 83.3%, and dose-corrected was 25.5%. Using basic or dose-corrected adherence, the treatment effect of vericiguat was consistent across adherence to guidelines groups, with or without multivariable adjustment with no treatment heterogeneity., Conclusions: Patients in VICTORIA were well treated with heart failure with reduced ejection fraction medications. The efficacy of vericiguat was consistent across background therapy with very high adherence to guidelines accounting for patient-level indications, contraindications, and tolerance., Registration: URL: https://www., Clinicaltrials: gov; Unique identifier: NCT02861534., Competing Interests: Disclosures Dr Ezekowitz: Research grants from Bayer, Merck, Servier, Amgen Sanofi, Novartis, Cytokinetics, American Regent, and Applied Therapeutics; consulting fees from Bayer, Merck, Servier, Amgen, Sanofi, Novartis, Cytokinetics, American Regent, and Applied Therapeutics.

Background: Age and sex influence treatment and outcomes in patients with heart failure (HF)., Objectives: The authors examined the associations of age and sex with clinical characteristics, background therapies, outcomes, and response to vericiguat in this post hoc analysis of 5,050 VICTORIA (Vericiguat Global Study in Subjects With Heart Failure With Reduced Ejection Fraction) patients with HF and reduced ejection fraction; 1,568 (31%) were ≥75 years of age, of whom 445 (24%) were women., Methods: Clinical characteristics were compared across age (<65, 65 to <75, and ≥75 years) and sex. The treatment effect of vericiguat was estimated by age and sex on the primary composite outcome (time to first HF hospitalization or cardiovascular death) using Cox proportional hazards regression., Results: Compared with younger patients, those ≥75 years of age had more class III and IV symptoms, higher N-terminal pro-B-type natriuretic peptide levels, and worse kidney function but had the lowest use of triple therapy. No sex differences in triple therapy existed by age, but achieving target doses of triple therapy was less likely in older patients. Men ≥75 years of age were more than twice as likely to receive defibrillators and 65% more likely to undergo cardiac resynchronization than women. The primary composite outcome was nominally lower in women than men across all age groups. Vericiguat dosing did not differ between sexes in each age group, and its beneficial effect on the primary endpoint was not modified by age (continuous age, P interaction  = 0.169; categorical age, P interaction  = 0.189); and sex (3-way interaction; P = 0.847)., Conclusions: Although elderly women received less intense background HF therapy than men, their prognosis was nominally better. The benefit of vericiguat was independent of age and sex.

Background: ST-segment-elevation myocardial infarction (STEMI) guidelines recommend pharmaco-invasive treatment if timely primary percutaneous coronary intervention (PCI) is unavailable. Full-dose tenecteplase is associated with an increased risk of intracranial hemorrhage in older patients. Whether pharmaco-invasive treatment with half-dose tenecteplase is effective and safe in older patients with STEMI is unknown., Methods: STREAM-2 (Strategic Reperfusion in Elderly Patients Early After Myocardial Infarction) was an investigator-initiated, open-label, randomized, multicenter study. Patients ≥60 years of age with ≥2 mm ST-segment elevation in 2 contiguous leads, unable to undergo primary PCI within 1 hour, were randomly assigned (2:1) to half-dose tenecteplase followed by coronary angiography and PCI (if indicated) 6 to 24 hours after randomization, or to primary PCI. Efficacy end points of primary interest were ST resolution and the 30-day composite of death, shock, heart failure, or reinfarction. Safety assessments included stroke and nonintracranial bleeding., Results: Patients were assigned to pharmaco-invasive treatment (n=401) or primary PCI (n=203). Median times from randomization to tenecteplase or sheath insertion were 10 and 81 minutes, respectively. After last angiography, 85.2% of patients undergoing pharmaco-invasive treatment and 78.4% of patients undergoing primary PCI had ≥50% resolution of ST-segment elevation; their residual median sums of ST deviations were 4.5 versus 5.5 mm, respectively. Thrombolysis In Myocardial Infarction flow grade 3 at last angiography was ≈87% in both groups. The composite clinical end point occurred in 12.8% (51/400) of patients undergoing pharmaco-invasive treatment and 13.3% (27/203) of patients undergoing primary PCI (relative risk, 0.96 [95% CI, 0.62-1.48]). Six intracranial hemorrhages occurred in the pharmaco-invasive arm (1.5%): 3 were protocol violations (excess anticoagulation in 2 and uncontrolled hypertension in 1). No intracranial bleeding occurred in the primary PCI arm. The incidence of major nonintracranial bleeding was low in both groups (<1.5%)., Conclusions: Halving the dose of tenecteplase in a pharmaco-invasive strategy in this early-presenting, older STEMI population was associated with electrocardiographic changes that were at least comparable to those after primary PCI. Similar clinical efficacy and angiographic end points occurred in both treatment groups. The risk of intracranial hemorrhage was higher with half-dose tenecteplase than with primary PCI. If timely PCI is unavailable, this pharmaco-invasive strategy is a reasonable alternative, provided that contraindications to fibrinolysis are observed and excess anticoagulation is avoided., Registration: URL: https://www., Clinicaltrials: gov; Unique identifier: NCT02777580., Competing Interests: Disclosures Dr Van de Werf reports institutional grants from Boehringer Ingelheim.

Background: Hospitalization due to heart failure (HFH) is a major source of morbidity, consumes significant economic resources and is a key endpoint in HF clinical trials. HFH events vary in severity and implications, but they are typically considered equivalent when analyzing clinical trial outcomes., Objectives: We aimed to evaluate the frequency and severity of HF events, assess treatment effects and describe differences in outcomes by type of HF event in VICTORIA (Vericiguat Global Study in Subjects with Heart Failure with Reduced Ejection Fraction)., Methods: VICTORIA compared vericiguat with placebo in patients with HF with reduced ejection fraction (< 45%) and a recent worsening HF event. All HFHs were prospectively adjudicated by an independent clinical events committee (CEC) whose members were blinded to treatment assignment. We evaluated the frequency and clinical impact of HF events by severity, categorized by highest intensity of HF treatment (urgent outpatient visit or hospitalization treated with oral diuretics, intravenous diuretics, intravenous vasodilators, intravenous inotropes, or mechanical support) and treatment effect by event categories., Results: In VICTORIA, 2948 HF events occurred in 5050 enrolled patients. Overall total CEC HF events for vericiguat vs placebo were 43.9 vs 49.1 events/100 patient-years (P = 0.01). Hospitalization for intravenous diuretics was the most common type of HFH event (54%). HF event types differed markedly in their clinical implications for both in-hospital and post-discharge events. We observed no difference in the distribution of HF events between randomized treatment groups (P = 0.78)., Conclusion: HF events in large global trials vary significantly in severity and clinical implications, which may have implications for more nuanced trial design and interpretation., Clinical Trial Registration: ClinicalTrials.gov (NCT02861534)., (Copyright © 2023 Elsevier Inc.

Aim: Vericiguat significantly reduced the primary composite outcome of heart failure (HF) hospitalization or cardiovascular death in the VICTORIA trial. It is unknown if these outcome benefits are related to reverse left ventricular (LV) remodelling with vericiguat in patients with HF with reduced ejection fraction (HFrEF). The aim of this study was to compare the effects of vericiguat versus placebo on LV structure and function after 8 months of therapy in patients with HFrEF., Methods and Results: Standardized transthoracic echocardiography (TTE) was performed at baseline and after 8 months of therapy in a subset of HFrEF patients in VICTORIA. The co-primary endpoints were changes in LV end-systolic volume index (LVESVI) and LV ejection fraction (LVEF). Quality assurance and central reading were performed by an echocardiographic core laboratory blinded to treatment assignment. A total of 419 patients (208 vericiguat, 211 placebo) with high-quality paired TTE at baseline and 8 months were included. Baseline clinical characteristics were well balanced between treatment groups and echocardiographic characteristics were representative of patients with HFrEF. LVESVI significantly declined (60.7 ± 26.8 to 56.8 ± 30.4 ml/m 2 ; p < 0.01) and LVEF significantly increased (33.0 ± 9.4% to 36.1 ± 10.2%; p < 0.01) in the vericiguat group, but similarly in the placebo group (absolute changes for vericiguat vs. placebo: LVESVI -3.8 ± 15.4 vs. -7.1 ± 20.5 ml/m 2 ; p = 0.07 and LVEF +3.2 ± 8.0% vs. +2.4 ± 7.6%; p = 0.31). The absolute rate per 100 patient-years of the primary composite endpoint at 8 months tended to be lower in the vericiguat group (19.8) than the placebo group (29.6) (p = 0.07)., Conclusions: In this pre-specified echocardiographic study, significant improvements in LV structure and function occurred over 8 months in both vericiguat and placebo in a high-risk HFrEF population with recent worsening HF. Further studies are warranted to define the mechanisms of vericiguat's benefit in HFrEF., (© 2023 The Authors.

Background: Vericiguat reduced the risk of cardiovascular death (CVD) or hospitalization for heart failure (HF) in patients with worsening HF and reduced left ventricular ejection fraction (LVEF)., Objectives: The authors assessed the association of LVEF with biomarker levels, risk of outcome, and whether the effect of vericiguat was homogeneous across LVEF in the VICTORIA (Vericiguat Global Study in Subjects with Heart Failure With Reduced Ejection Fraction) trial., Methods: Patients were grouped by LVEF tertiles (≤24%, 25%-33%, and >33%). Patient characteristics, clinical outcomes, and efficacy and safety of vericiguat were examined by tertile. Prespecified biomarkers including N-terminal pro-B-type natriuretic peptide, cardiac troponin T, growth differentiation factor 15, interleukin 6, high-sensitivity C-reactive protein, and cystatin C were examined., Results: The mean LVEF was 29% ± 8% (range: 5%-45%). A pattern of higher N-terminal pro-B-type natriuretic peptide, high-sensitivity C-reactive protein, and interleukin 6 was evident in patients in the lowest LVEF tertile vs the other tertiles. Patients with lower LVEF experienced higher rates of the composite outcome (41.7%, 36.3%, and 33.4% for LVEF ≤24, 25-33, and >33; P < 0.001). There was no significant treatment effect heterogeneity of vericiguat across LVEF groups (adjusted HR from lowest to highest tertiles: 0.79 [95% CI: 0.68-0.94]; 0.95 [95% CI: 0.82-1.11]; 0.94 [95% CI: 0.79-1.11]; P for interaction = 0.222), although the HR was numerically lower in the lowest tertile. There was also no heterogeneity of effect for CVD and HF hospitalization individually (P interaction for CVD = 0.964; HF hospitalization = 0.438). Discontinuation of treatment because of adverse events, symptomatic hypotension, or syncope was consistent across the range of LVEF., Conclusions: Patients with lower LVEF had a distinctive biomarker profile and a higher risk for adverse clinical outcomes vs those with a higher LVEF. There was no significant interaction for the benefit of vericiguat across LVEF tertiles, although the largest signal for benefit in both the primary outcome and HF hospitalizations was noted in tertile 1 (LVEF ≤24%).

Background: The association between frailty and health status in patients with heart failure with preserved ejection fraction (HFpEF) is not well known., Objectives: The authors examined the association between: 1) patient-reported frailty, measured by the Fried frailty phenotype, Kansas City Cardiomyopathy Questionnaire Physical Limitation Score (KCCQ-PLS), 6-minute walking distance (6MWD), and other baseline characteristics; 2) baseline frailty compared with KCCQ-PLS and 24-week 6MWD; 3) frailty and changes in KCCQ-PLS and 6MWD; and 4) vericiguat and frailty at 24 weeks., Methods: In a post hoc analysis, patients in the VITALITY-HFpEF (Patient-reported Outcomes in Vericiguat-treated Patients With HFpEF) trial were categorized as not frail (0 symptoms), prefrail (1-2 symptoms), and frail (≥3 symptoms) according to patient-reported number of frailty symptoms. Correlations and linear regression models were used to examine the association between frailty and other measures, and between frailty and KCCQ-PLS at baseline with 24-week 6MWD., Results: Among 739 patients, 27.3% were not frail, 37.6% were prefrail, and 35.0% were frail at baseline. Frail patients were older, more likely to be women, and less likely to be from Asia. Baseline KCCQ-PLS and 6MWD (mean ± SD) among not frail, prefrail, and frail patients was 68.2 ± 23.2, 61.7 ± 22.6, and 48.4 ± 23.8 and 328.5 ± 117.1 m, 310.8 ± 98.9 m, and 250.7 ± 104.3 m (P < 0.01 for both). After accounting for baseline 6MWD, frailty status at baseline, but not KCCQ-PLS, was significantly associated with 6MWD at 24 weeks. By 24 weeks, 47.5% of patients had no change in frailty, 45.5% had become less frail, and 7.0% had become more frail. Treatment with vericiguat did not alter frailty status at 24 weeks., Conclusions: Patient-reported frailty is modestly correlated with both the KCCQ-PLS and 6MWD but offers prognostic insight into 6MWD at 24 weeks.

Background: Circulating biomarkers may be useful in understanding prognosis and treatment efficacy in heart failure with reduced ejection fraction. In the VICTORIA (Vericiguat Global Study in Subjects with Heart Failure with Reduced Ejection Fraction) trial, vericiguat, a soluble guanylate cyclase stimulator, decreased the primary outcome of cardiovascular death or heart failure hospitalization in heart failure with reduced ejection fraction. We evaluated biomarkers of cardiac injury, inflammation, and renal function for associations with outcomes and vericiguat treatment effect., Methods and Results: High-sensitivity cardiac troponin T (hs-cTnT), growth differentiation factor-15 (GDF-15), interleukin-6 (IL-6), high-sensitivity C-reactive protein (hs-CRP), and cystatin C were measured at baseline and 16 weeks. Associations of biomarkers with the primary outcome and its components were estimated. Interaction with study treatment was tested. Changes in biomarkers over time were examined by study treatment. One or more biomarkers were measured in 4652 (92%) of 5050 participants at baseline and 4063 (81%) at 16 weeks. After adjustment, higher values of hs-cTnT, growth differentiation factor-15, and interleukin-6 were associated with the primary outcome, independent of N-terminal pro-B-type natriuretic peptide. Higher hs-cTnT values were associated with a hazard ratio per log standard deviation of 1.21 (95% confidence interval 1.14-1.27). A treatment interaction with vericiguat was evident with hs-cTnT and cardiovascular death (P = .04), but not HF hospitalization (P = .38). All biomarkers except cystatin C decreased over 16 weeks and no relationship between treatment assignment and changes in biomarker levels was observed., Conclusions: hs-cTnT, growth differentiation factor-15, and interleukin-6 levels were associated with risk of the primary outcome in VICTORIA (Vericiguat Global Study in Subjects with Heart Failure with Reduced Ejection Fraction). Uniquely, lower hs-cTnT was associated with a lower rate of cardiovascular death but not HF hospitalization after treatment with vericiguat., (Copyright © 2023 Elsevier Inc. All rights reserved.)

Remarkable advances in the management of coronary artery disease have enhanced our approach to left main coronary artery (LMCA) disease. The traditional role of coronary artery bypass graft surgery has been challenged by the less invasive percutaneous coronary interventional approach. Additionally, major strides in optimal medical therapy now provide a rich menu of treatment choices in selected circumstances. Although a LMCA stenosis >70% is an acceptable threshold for revascularization, those patients with a LMCA narrowing between 40 and 69% present a more complex scenario. This review examines the relative merits of the different treatment options, addresses key diagnostic and therapeutic unknowns, and identifies future work likely to advance progress., Competing Interests: Conflict of interest: Armstrong reports grants and personal fees from Merck, Bayer, and Boehringer Ingelheim; grants from Boehringer Ingelheim/Eli Lilly and CSL Limited; and personal fees from Novo Nordisk.

Vericiguat, a novel stimulator of soluble guanylate cyclase (sGC), is indicated for the treatment of patients following a hospitalization for heart failure or need for outpatient intravenous diuretics, with symptomatic chronic heart failure and ejection fraction less than 45%. Pharmacokinetic (PK) data from the phase II trial SOCRATES-REDUCED (Soluble Guanylate Cyclase Stimulator in Heart Failure Study) and the phase III trial VICTORIA (Vericiguat Global Study in Patients With Heart Failure With Reduced Ejection Fraction) were used to characterize vericiguat PK. A total of 8,092 concentration records from 2,321 participants (362 from SOCRATES-REDUCED and 1,959 from VICTORIA) were utilized for the development of the population PK model. The final PK model was a one-compartment model with first-order absorption and linear elimination. Baseline body weight and time-varying body weight were identified as statistically significant covariates affecting apparent clearance (CL/F) and volume of distribution, respectively. Age, sex, race, bilirubin, estimated glomerular filtration rate, and albumin did not affect vericiguat PK. Baseline disease-related factors, such as left ventricular ejection fraction, New York Heart Association (NYHA) class, and N-terminal pro B-type natriuretic peptide, also did not influence vericiguat PK. Since vericiguat is a titrated drug, the impact of vericiguat PK on the titration to and maintenance of the target dose in VICTORIA was assessed. The distribution of steady-state doses in VICTORIA was similar across CL/F quartiles, suggesting that the ability to reach and maintain dosing at the target 10-mg dose was not related to vericiguat exposure., (© 2022 Merck Sharp & Dohme LLC, Cognigen division, Simulations Plus, Inc and Bayer AG.

Aim: We assessed a subset of the 5040 patients in VICTORIA receiving sacubitril/valsartan, either at randomization (n = 731) or post-randomization drop-in use (n = 425), to evaluate the relationship between the efficacy and safety of combination therapy with vericiguat., Methods and Results: The efficacy of vericiguat on the primary composite endpoint, heart failure (HF) hospitalization, and all-cause mortality was assessed. Safety outcomes included symptomatic hypotension, syncope, worsening renal function, and hyperkalaemia. At randomization, 731 patients received sacubitril/valsartan; they were more frequently from Western Europe or North America, had lower ejection fraction and systolic blood pressure, and more use of triple background HF therapy (65.9% vs. 58.6%), biventricular pacemakers (17.9% vs. 14.1%), or implantable cardioverter defibrillators (42.3% vs. 25.3%). For patients on versus not on sacubitril/valsartan at randomization, adjusted hazard ratios (95% confidence intervals) for vericiguat's treatment effect on the primary composite outcome, cardiovascular death, and HF hospitalization were 0.92 (0.71-1.19) versus 0.89 (0.80-0.98), 0.71 (0.45-1.12) versus 0.95 (0.82-1.11), and 0.98 (0.74-1.29) versus 0.87 (0.78-0.98), respectively. No significant interaction existed between sacubitril/valsartan and vericiguat's treatment effect (p-values for interaction: 0.81, 0.23 and 0.47, respectively). Post-randomization, more drop-in sacubitril/valsartan use occurred in those assigned to placebo (n = 238) versus vericiguat (n = 187) (p = 0.007). Symptomatic hypotension (21.0% vs. 23.1%; p = 0.41), renal dysfunction (29.9% vs. 31.9%; p = 0.50), and hyperkalaemia (10.3% vs. 7.9%; p = 0.20) in patients receiving sacubitril/valsartan (n = 992) for ≥3 months were not different by treatment arm., Conclusions: Concomitant use of sacubitril/valsartan for at least 3 months did not alter the efficacy of vericiguat and was similarly safe and tolerated in both study arms. Sacubitril/valsartan was initiated more frequently after randomization in patients assigned to placebo versus vericiguat., Clinical Trial Registration: ClinicalTrials.gov NCT02861534., (© 2022 European Society of Cardiology.)

Background: The effect of vericiguat on sequential N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels and influence of this relationship on clinical outcomes is unknown., Objectives: This study assessed the relationship between changes in NT-proBNP and the primary outcome (cardiovascular death or heart failure hospitalization); evaluated the effect of vericiguat on changes in NT-proBNP; and explored the association between the efficacy of vericiguat and changes in NT-proBNP., Methods: NT-proBNP was measured at randomization and at 16, 32, 48, and 96 weeks in 4,805 of 5,050 patients. The association between NT-proBNP change at week 16 and the primary outcome was assessed. The relationship between changes in NT-proBNP and the primary outcome according to treatment group was assessed by using joint modeling and mediation analysis., Results: A significant and sustained decline in NT-proBNP levels was seen in both treatment groups. After week 16, NT-proBNP levels decreased more with vericiguat vs placebo (any reduction: odds ratio [OR]: 1.45 [95% CI: 1.28-1.65]; P < 0.001; ≥50% reduction: OR: 1.27 [95% CI: 1.10-1.47]; P = 0.001) and were less likely to increase (≥20% increase: OR: 0.68 [95% CI: 0.59-0.78]; P < 0.001; ≥50% increase: OR: 0.70 [95% CI: 0.59-0.82]; P < 0.001). The treatment effect related to serial NT-proBNP on the primary composite outcome was HR: 0.96 (95% CI: 0.95-0.99) at week 16, which increased to HR: 0.90 (95% CI: 0.85-0.96) at week 48; the average extent of mediation of the composite outcome related to NT-proBNP was 45%., Conclusions: In patients with worsening HFrEF, vericiguat significantly decreased NT-proBNP levels compared with placebo. This change appeared associated with a modest relative improvement in the primary outcome of cardiovascular death or heart failure hospitalization.

Background: Patients with heart failure (HF) and a reduced ejection fraction (HFrEF) who experience worsening HF (WHF) events are at increased risk of adverse outcomes and experience significant morbidity and mortality. We herein describe the epidemiology of these patients and identify those potentially eligible for vericiguat therapy in this population-based study., Methods and Results: This retrospective cohort study included hospitalized or emergency department patients with a primary diagnosis of HF and a left ventricular ejection fraction (LVEF) of less than 45% diagnosed between April 1, 2009, and March 31, 2019 in Alberta, Canada, with follow-up to March 31, 2020. Inclusion criteria from the VerICiguaT Global Study in Subjects with Heart Failure with Reduced Ejection (VICTORIA) trial were applied to explore eligibility for vericiguat. Among 25,629 patients with HF and LVEF data, 9948 (38.8%) had HFrEF, of which 5259 (52.8%) experienced WHF at some point during a median 5.8 years of follow-up, and 38.3% of those met the vericiguat trial eligibility criteria. Compared with patients with HFrEF without WHF, those with WHF were older, with more comorbidities, worse renal function, and similar LVEF status, but greater use of HF medications at baseline. At the time of WHF, 27% of those with HFrEF and WHF were on triple therapy, 50.6% were on dual therapy, and 15.4% were on monotherapy. All-cause mortality and the composite outcome of all-cause mortality or cardiovascular hospitalization at 1-year of follow-up were higher in the HFrEF with WHF cohort compared with HFrEF without WHF (adjusted hazard ratios of 1.92 and 1.51, respectively, both P < .0001)., Conclusions: Approximately one-half of patients with HFrEF experienced WHF over the long-term follow-up. Most were not on triple therapy, highlighting the underuse of the existing standard-of-care treatments and opportunities for application of newer therapies; more than one-third of patients with HFrEF may be eligible for vericiguat., Lay Summary: Among patients with heart failure (HF), those who experience worsening HF (WHF) are at increased risk of adverse outcomes. A few new therapies, including vericiguat, have emerged recently for patients with HF and reduced ejection fraction. However, the epidemiology, treatment patterns, and outcomes of patients with WHF in large representative populations is unclear. In the current study, approximately one-half of the patients with HF and reduced ejection fraction experienced WHF and 38.3% were potentially eligible for vericiguat therapy. The guideline-recommended therapies were under-utilized among patients with WHF, which highlights the need for initiatives to address this care gap., Competing Interests: Conflict of Interest Disclosures J.A.E. and P.W.A. were investigators at the VICTORIA trial.

Background: For patients hospitalized for heart failure with reduced ejection fraction (HFrEF), guidelines recommend optimization of medical therapy prior to discharge. The degree to which changes in medical therapy occur during hospitalizations for HFrEF in North American clinical practice is unclear., Methods: The VICTORIA registry (Vericiguat Global Study in Subjects with Heart Failure with Reduced Ejection Fraction) enrolled patients hospitalized for worsening chronic HFrEF across 51 sites in the United States and Canada from February 2018-January 2019. In patients with complete medication data who were not receiving dialysis, use and dose of angiotensin-converting enzyme inhibitor (ACEI)/angiotensin II receptor blocker (ARB), angiotensin receptor neprilysin inhibitor (ARNI), beta-blocker, mineralocorticoid receptor antagonist (MRA), and sodium glucose cotransporter-2 inhibitors (SGLT2i) were assessed at admission and discharge., Results: Of 1695 patients, the median (IQR) age was 69 (59-79) years, and 33% were women. Among eligible patients, 33%, 25% and 55% were not prescribed ACEI/ARB/ARNI, beta-blocker, and MRA at discharge, respectively; 99% were not prescribed SGLT2i. For each medication, > 50% of patients remained on stable subtarget doses or no medication during hospitalization. In-hospital rates of initiation/dose increase were 20% for ACEI/ARB, 4% for ARNI, 20% for beta-blocker, 22% for MRA, and < 1% for SGLT2i; corresponding rates of dose decrease/discontinuation were 11%, 2%, 9%, 5%, and < 1%, respectively. Overall, 17% and 28% of eligible patients were prescribed triple therapy prior to admission and at discharge, respectively. At both admission and discharge, 1% of patients were prescribed triple therapy at target doses. Across classes of medication, multiple factors were independently associated with higher likelihood of in-hospital initiation/dosing increase (eg, Canadian enrollment, white race, admission to intensive care units) and discontinuation/dosing decrease (eg, worse renal function, admission to intensive care units)., Conclusions: In this contemporary North American registry of patients hospitalized for worsening chronic HFrEF, for each recommended medical therapy, the large majority of eligible patients remained on stable subtarget doses or without medication at admission and discharge. Although most patients had no alterations in medical therapy, hospitalization in Canada and multiple patient characteristics were associated with higher likelihood of favorable in-hospital medication changes., (Copyright © 2022 Elsevier Inc.

Background: We examined the effects of vericiguat compared with placebo in patients with heart failure with reduced ejection fraction enrolled in VICTORIA (Vericiguat Global Study in Patients With Heart Failure With Reduced Ejection Fraction) on health status outcomes measured by the Kansas City Cardiomyopathy Questionnaire (KCCQ) and evaluated whether clinical outcomes varied by baseline KCCQ score., Methods: KCCQ was completed at baseline and 4, 16, and 32 weeks. We assessed treatment effect on KCCQ using a mixed-effects model adjusting for baseline KCCQ and stratification variables. Cox proportional-hazards modeling was performed to evaluate the effect of vericiguat on clinical outcomes by tertiles of baseline KCCQ clinical summary score (CSS), total symptom score (TSS), and overall summary score (OSS)., Results: Of 5050 patients, 4664, 4741, and 4470 had KCCQ CSS (median [25th to 75th], 65.6 [45.8-81.8]), TSS (68.8 [47.9-85.4]), and OSS (59.9 [42.0-77.1]) at baseline; 94%, 88%, and 82% had data at 4, 16, and 32 weeks. At 16 weeks, CSS improved by a median of 6.3 in both arms; no significant differences in improvement were seen for TSS and OSS between the 2 groups ( P =0.69, 0.97, and 0.13 for CSS, TSS, and OSS). Trends were similar at 4 and 32 weeks. Vericiguat versus placebo reduced cardiovascular death or heart failure hospitalization risk similarly across tertiles of baseline KCCQ CSS, TSS, and OSS (interaction P =0.13, 0.21, and 0.65)., Conclusions: Vericiguat did not significantly improve KCCQ scores compared with placebo. Vericiguat reduced the risk of cardiovascular death or heart failure hospitalization across the range of baseline health status., Registration: URL: https://www., Clinicaltrials: gov; Unique identifier: NCT02861534.

Early prediction of significant morbidity or mortality in patients with acute ST-segment elevation myocardial infarction (STEMI) represents an unmet clinical need. In phenotypically matched population of 139 STEMI patients (72 cases, 67 controls) treated with primary percutaneous coronary intervention, we explored associations between a 24-h relative change from baseline in the concentration of 91 novel biomarkers and the composite outcome of death, heart failure, or shock within 90 days. Additionally, we used random forest models to predict the 90-day outcomes. After adjustment for false discovery rate, the 90-day composite was significantly associated with concentration changes in 14 biomarkers involved in various pathophysiologic processes including: myocardial fibrosis/remodeling (collagen alpha-1, cathepsin Z, metalloproteinase inhibitor 4, protein tyrosine phosphatase subunits), inflammation, angiogenesis and signaling (interleukin 1 and 2 subunits, growth differentiation factor 15, galectin 4, trefoil factor 3), bone/mineral metabolism (osteoprotegerin, matrix extracellular phosphoglycoprotein and tartrate-resistant acid phosphatase), thrombosis (tissue factor pathway inhibitor) and cholesterol metabolism (LDL-receptor). Random forest models suggested an independent association when inflammatory markers are included in models predicting the outcomes within 90 days. Substantial heterogeneity is apparent in the early proteomic responses among patients with acutely reperfused STEMI patients who develop death, heart failure or shock within 90 days. These findings suggest the need to consider synergistic multi-biomarker strategies for risk stratification and to inform future development of novel post-myocardial infarction therapies., (© 2021.

Aims: Coronary artery disease (CAD) portends worse outcomes in heart failure (HF). We aimed to characterize patients with CAD and worsening HF with reduced ejection fraction (HFrEF) and evaluate post hoc whether vericiguat treatment effect varied according to CAD., Methods and Results: Cox proportional hazards were generated for the primary endpoint of cardiovascular death or HF hospitalization (CVD/HFH). CAD was defined as previous myocardial infarction, percutaneous coronary intervention, or coronary artery bypass grafting. Of 5048 patients in VICTORIA with available data on CAD status, 2704 had CAD and were older, were more frequently male, diabetic, and had a lower glomerular filtration rate than those without CAD (all p <0.0001). Use of implantable cardioverter defibrillators and cardiac resynchronization therapy (CRT) was higher in patients with versus without CAD (33.5% vs. 21.1%; p <0.0001 and 16.3% vs. 12.8%; p = 0.0006). The primary endpoint of CVD/HFH was higher in those with versus without CAD (40.6 vs. 30.1/100 patient-years; adjusted hazard ratio [HR] 1.23; p <0.001) as was all-cause mortality (17.9% vs. 12.7%; adjusted HR 1.32; p <0.001). The primary outcome of CVD/HFH associated with vericiguat in patients with or without CAD was 38.8 versus 27.6 per 100 patient-years and for placebo was 42.6 versus 32.7 per 100 patient-years (interaction p = 0.78)., Conclusion: In this post hoc study, CAD was associated with more CVD and HFH in patients with HFrEF and worsening HF. Vericiguat was beneficial and safe regardless of concomitant CAD., (© 2022 European Society of Cardiology.)

Aims: Clinically important thresholds in patient-reported outcomes measures like the Kansas City Cardiomyopathy Questionnaire (KCCQ) have not been defined for patients with heart failure and preserved ejection fraction (HFpEF). The aim of this study was to estimate meaningful thresholds for improvement or worsening in the KCCQ physical limitation score (PLS) in patients with HFpEF., Methods and Results: In this pre-specified analysis from VITALITY-HFpEF, anchor- and distribution-based approaches were used to estimate thresholds for improvement or worsening in the KCCQ-PLS using Patient Global Impression of Change (PGIC) as an anchor. The KCCQ-PLS contains six elements, with each increment in response resulting in a change of 4.17 points when converted to a 0-100 scale. The mean change in KCCQ-PLS from baseline to week 12 was calculated for each PGIC group to estimate a meaningful within-patient change. Of 789 patients enrolled, 698 had complete KCCQ-PLS and PGIC data at week 12. The mean (± standard deviation) changes in KCCQ-PLS corresponding to PGIC changes of 'a little better', 'better', and 'much better' were 5.7 ± 18.6, 11.6 ± 19.3, and 18.4 ± 25.3 points, respectively. The scores of patients who responded 'a little better' (n = 177) overlapped substantially with those who reported 'no change' (n = 193; mean change 2.8 ± 18.9). The mean change in KCCQ-PLS for patients responding 'a little worse' (n = 32) was -2.6 ± 18.0 points. The threshold for meaningful within-patient change in KCCQ-PLS based on distribution-based analyses was 12.3 points. Using area under the curve (AUC) analyses of KCCQ-PLS, the sensitivity and specificity of a 4.17-point change were 0.61 and 0.57, for an 8.33-point change they were 0.49 and 0.64, and for a 12.5-point change they were 0.44 and 0.72 for being at least a little better on the PGIC (AUC = 0.54)., Conclusion: In the VITALITY-HFpEF trial, a change in KCCQ-PLS of ≥8.33 points (corresponding to an improvement in ≥2 response categories of KCCQ-PLS) may represent the minimal clinically important difference for improvement and a change of ≤ -4.17 points (corresponding to a worsening in ≥1 response category of KCCQ-PLS) may suggest deterioration in patients with HFpEF., (© 2022 The Authors.

Objective: Phenotypic heterogeneity among patients with type 2 diabetes mellitus (T2DM) and atherosclerotic cardiovascular disease (ASCVD) is ill defined. We used cluster analysis machine-learning algorithms to identify phenotypes among trial participants with T2DM and ASCVD., Research Design and Methods: We used data from the Trial Evaluating Cardiovascular Outcomes with Sitagliptin (TECOS) study (n = 14,671), a cardiovascular outcome safety trial comparing sitagliptin with placebo in patients with T2DM and ASCVD (median follow-up 3.0 years). Cluster analysis using 40 baseline variables was conducted, with associations between clusters and the primary composite outcome (cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, or hospitalization for unstable angina) assessed by Cox proportional hazards models. We replicated the results using the Exenatide Study of Cardiovascular Event Lowering (EXSCEL) trial., Results: Four distinct phenotypes were identified: cluster I included Caucasian men with a high prevalence of coronary artery disease; cluster II included Asian patients with a low BMI; cluster III included women with noncoronary ASCVD disease; and cluster IV included patients with heart failure and kidney dysfunction. The primary outcome occurred, respectively, in 11.6%, 8.6%, 10.3%, and 16.8% of patients in clusters I to IV. The crude difference in cardiovascular risk for the highest versus lowest risk cluster (cluster IV vs. II) was statistically significant (hazard ratio 2.74 [95% CI 2.29-3.29]). Similar phenotypes and outcomes were identified in EXSCEL., Conclusions: In patients with T2DM and ASCVD, cluster analysis identified four clinically distinct groups. Further cardiovascular phenotyping is warranted to inform patient care and optimize clinical trial designs., (© 2021 by the American Diabetes Association.)

Background Although safety and tolerability of vericiguat were established in the VICTORIA (Vericiguat Global Study in Subjects With Heart Failure With Reduced Ejection Fraction) trial in patients with heart failure with reduced ejection fraction, some subgroups may be more susceptible to symptomatic hypotension, such as older patients, those with lower baseline systolic blood pressure (SBP), or those concurrently taking angiotensin receptor neprilysin inhibitors. We described the SBP trajectories over time and compared the occurrence of symptomatic hypotension or syncope by treatment arm in potentially vulnerable subgroups in VICTORIA. We also evaluated the relation between the efficacy of vericiguat and baseline SBP. Methods and Results Among patients receiving at least 1 dose of the study drug (n=5034), potentially vulnerable subgroups were those >75 years old (n=1395), those with baseline SBP 100-110 mm Hg (n=1344), and those taking angiotensin receptor neprilysin inhibitors (n=730). SBP trajectory was plotted as mean change from baseline over time. The treatment effect on time to symptomatic hypotension or syncope was evaluated overall and by subgroup, and the primary efficacy composite outcome (heart failure hospitalization or cardiovascular death) across baseline SBP was examined using Cox proportional hazards models. SBP trajectories showed a small initial decline in SBP with vericiguat in those >75 years old (versus younger patients), as well as those receiving angiotensin receptor neprilysin inhibitors (versus none), with SBP returning to baseline thereafter. Patients with SBP <110 mm Hg at baseline showed a trend to increasing SBP over time, which was similar in both treatment arms. Safety event rates were generally low and similar between treatment arms within each subgroup. In Cox proportional hazards analysis, there were similar numbers of safety events with vericiguat versus placebo (adjusted hazard ratio [HR], 1.18; 95% CI, 0.99-1.39; P =0.059). No difference existed between treatment arms in landmark analysis beginning after the titration phase (ie, post 4 weeks) (adjusted HR, 1.14; 95% CI, 0.93-1.38; P =0.20). The benefit of vericiguat compared with placebo on the primary composite efficacy outcome was similar across the spectrum of baseline SBP ( P for interaction=0.32). Conclusions These data demonstrate the safety of vericiguat in a broad population of patients with worsening heart failure with reduced ejection fraction, even among those predisposed to hypotension. Vericiguat's efficacy persisted regardless of baseline SBP. Registration URL: https://www.clinicaltrials.gov; Unique identifier: NCT02861534.

Background: In the VICTORIA trial (Vericiguat Global Study in Patients with Heart Failure with Reduced Ejection Fraction), anemia occurred more often in patients treated with vericiguat (7.6%) than with placebo (5.7%). We explored the association between vericiguat, randomization hemoglobin, development of anemia, and whether the benefit of vericiguat related to baseline hemoglobin., Methods: Anemia was defined as hemoglobin <13.0 g/dL in men and <12.0 g/dL in women (World Health Organization Anemia). Adverse events reported as anemia were also evaluated. We assessed the risk-adjusted relationship between hemoglobin and hematocrit with the primary outcome (composite of cardiovascular death or heart failure hospitalization) and the time-updated hemoglobin relationship to outcomes., Results: At baseline, 1719 (35.7%) patients had World Health Organization anemia; median hemoglobin was 13.4 g/L (25th, 75th percentile: 12.1, 14.7 g/dL). At 16 weeks from randomization, 1643 patients had World Health Organization anemia (284 new for vericiguat and 219 for placebo), which occurred more often with vericiguat than placebo ( P <0.001). After 16 weeks, no further decline in hemoglobin occurred over 96 weeks of follow-up and the ratio of hemoglobin/hematocrit remained constant. Overall, adverse event anemia occurred in 342 patients (7.1%). A lower hemoglobin was unrelated to the treatment benefit of vericiguat (versus placebo) on the primary outcome. In addition, analysis of time-updated hemoglobin revealed no association with the treatment effect of vericiguat (versus placebo) on the primary outcome., Conclusions: Anemia was common at randomization and lower hemoglobin was associated with a greater frequency of clinical events. Although vericiguat modestly lowered hemoglobin by 16 weeks, this effect did not further progress nor was it related to the treatment benefit of vericiguat.

Background: Data are limited data on the prevalence of cardiovascular disease (CVD) and multimorbidity in contemporary cohorts of high-cost users (HCUs) in Canada.We examined the following: (i) the prevalence of CVD, with a comparison of total healthcare costs among HCUs with vs without CVD; (ii) the contribution of other comorbidities to costs among HCUs with CVD; and (iii) the trajectory of healthcare costs in the years before and after becoming an HCU., Methods: The study included adult Alberta patients in the Canadian Institutes of Health Research/Canadian Institute for Health Information Dynamic Cohort of Complex, High System Users from 2011-2012 through 2014-2015. We examined total healthcare costs, including hospital, ambulatory care, physician services, and drugs., Results: Among 88,536 HCUs, 23.4% had no CVD, 28.9% were hospitalized with a primary diagnosis of CVD, and 47.7% were hospitalized with a secondary diagnosis of CVD. Total healthcare costs were $2.0 billion (20.4% non-hospital costs), $2.8 billion (24.1% non-hospital costs), and $4.9 billion (19.8% non-hospital costs), respectively, in the 3 groups. Many HCUs with CVD were frail (74.2%) and many had diabetes (33.8%) or chronic obstructive pulmonary disease (27.9%), which contributed to higher costs and mortality. Healthcare expenditures in HCUs with CVD were several times higher than per capita health expenditures in the years prior to, and following, their inclusion in the dynamic HCU cohort., Conclusions: CVD is very common in HCUs of healthcare. HCUs with CVD have high rates of frailty and multimorbidity. Further research is needed to identify and intervene earlier, in order to flatten the cost curve in these complex patients., (© 2021 The Authors.)

Background: Randomized controlled trials (RCTs) often target enrollment of patients with demographics and outcomes less representative of the broader population of interest. To provide context for the VICTORIA trial (Vericiguat Global Study in Subjects With Heart Failure With Reduced Ejection Fraction), we designed a registry of hospitalized patients with worsening heart failure to characterize their clinical profile, outcomes, and reasons for their nonparticipation in a RCT., Methods: Fifty-one RCT sites in Canada and the United States participated. Eligible patients included those with chronic heart failure, hospitalized for heart failure, and an ejection fraction <45%; no other exclusions were applied. Sites identified patients between 2017 and 2019 during the RCT enrollment period. RCT eligibility criteria were applied, and non-mutually exclusive reasons for nonenrollment were captured. Mortality at 1 year was estimated via the Meta-Analysis Global Group in Chronic Heart Failure risk score or as observed in the RCT., Results: Overall, 2056 patients were enrolled in the registry; 61% (n=1256) were ineligible for the RCT, 37% (n=766) were eligible but not enrolled, and 2% (n=34) were also enrolled in the RCT. Registry participants had a median age of 70, 33% were women, and 63% were White. The median risk score predicted a 20.9% 1-year mortality, higher than in the RCT (predicted 14.7% and observed 11.5%). Major reasons for ineligibility in the RCT included the use of nitrates (23%), systolic blood pressure <100 mm Hg (12%), and substance use (11%) with other exclusion criteria <10%. For eligible patients, reasons for nonparticipation in the RCT included lack of interest in participating (28%), poor compliance (25%), inability to complete follow-up (23%), too sick (20%), unable to provide consent (17%), and distance from site (15%)., Conclusions: Patients with worsening heart failure in routine clinical practice exhibit high-risk features, and approximately one-third were eligible for an RCT but excluded. The majority of these nonparticipating patients had modifiable reasons. Registration: URL: https://www.clinicaltrials.gov; Unique identifier: NCT02861534.

Aims: Vericiguat reduced the primary composite outcome of cardiovascular death or heart failure (HF) hospitalization in patients with worsening HF with reduced ejection fraction (HFrEF) and a lower limit of baseline estimated glomerular filtration rate (eGFR) of 15 mL/min/1.73 m 2 . We evaluated the relationship between the efficacy of vericiguat and baseline and subsequent changes in renal function., Methods and Results: In VICTORIA, core laboratory serum creatinine was measured at baseline (n = 4956) and weeks 16, 32, and 48. Worsening renal function (WRF), defined as an increase ≥0.3 mg/dL in creatinine from baseline to week 16, was assessed via a Cox model with respect to subsequent primary events. Mean age was 69 years, 24% were female, and mean baseline eGFR was 61 mL/min/1.73 m 2 . During 48 weeks of treatment, the trajectories in eGFR and creatinine with vericiguat were similar to placebo (P = 0.50 and 0.18). The beneficial effects of vericiguat on the primary outcome were not influenced by baseline eGFR (interaction P = 0.48). WRF occurred in 15% of patients and was associated with worse outcomes (adjusted hazard ratio 1.28, 95% confidence interval 1.11-1.47; P < 0.001), but the beneficial effects of vericiguat on the primary outcome were similar in patients with or without WRF (interaction P = 0.76)., Conclusion: Renal function trajectories were similar between vericiguat- and placebo-treated patients and the beneficial effects of vericiguat on the primary outcome were consistent across the full range of eGFR and irrespective of WRF., (© 2021 The Authors.

Aims: We evaluated the relation between baseline and new-onset atrial fibrillation (AF) and outcomes, and assessed whether vericiguat modified the likelihood of new-onset AF in patients with worsening heart failure (HF) with reduced ejection fraction in VICTORIA., Methods and Results: Of 5050 patients randomized, 5010 with recorded AF status at baseline were analysed. Patients were classified into three groups: no known AF (n = 2661, 53%), history of AF alone (n = 992, 20%), and AF on randomization electrocardiogram (n = 1357, 27%). Compared with those with no AF, those with history of AF alone had a higher risk of cardiovascular death [adjusted hazard ratio (HR) 1.21, 95% confidence interval (CI) 1.01-1.47] without excess myocardial infarction or stroke; neither type of AF was associated with a higher risk of the primary composite outcome (time to cardiovascular death or first HF hospitalization), HF hospitalizations, or all cause-death. The beneficial effect of vericiguat on the primary composite outcome and its components was evident irrespective of AF status at baseline. Over a median follow-up of 10.8 months, new-onset AF occurred in 6.1% of those with no AF and 18.3% with history of AF alone (P < 0.0001). These events were not influenced by vericiguat treatment (adjusted HR 0.93, 95% CI 0.75-1.16; P = 0.51), but were associated with an increase in the hazard of both primary and secondary outcomes., Conclusions: Atrial fibrillation was present in nearly half of this high-risk population with worsening HF. A history of AF alone at baseline portends an increased risk of cardiovascular death. Neither type of AF affected the beneficial effect of vericiguat. Development of AF post-randomization was associated with an increase in both cardiovascular death and HF hospitalization which was not influenced by vericiguat., (© 2021 European Society of Cardiology.)

Background: The prediction of outcomes in patients with heart failure (HF) may inform prognosis, clinical decisions regarding treatment selection, and new trial planning. The VerICiguaT Global Study in Subjects With Heart Failure With Reduced Ejection Fraction included high-risk patients with HF with reduced ejection fraction and a recent worsening HF event. The study participants had a high event rate despite the use of contemporary guideline-based therapies. To provide generalizable predictive data for a broad population with a recent worsening HF event, we focused on risk prognostication in the placebo group., Methods and Results: Data from 2524 participants randomized to placebo with chronic HF (New York Heart Association functional class II-IV) and an ejection fraction of less than 45% were studied and backward variable selection was used to create Cox proportional hazards models for clinical end points, selecting from 66 candidate predictors. Final model results were produced, accounting for missing data, and nonlinearities. Optimism-corrected c-indices were calculated using 200 bootstrap samples. Over a median follow-up of 10.4 months, the primary outcome of HF hospitalization or cardiovascular death occurred in 972 patients (38.5%). Independent predictors of increased risk for the primary end point included HF characteristics (longer HF duration and worse New York Heart Association functional class), medical history (prior myocardial infarction), and laboratory values (higher N-terminal pro-hormone B-type natriuretic peptide, bilirubin, urate; lower chloride and albumin). Optimism-corrected c-indices were 0.68 for the HF hospitalization/cardiovascular death model, 0.68 for HF hospitalization/all-cause death, 0.72 for cardiovascular death, and 0.73 for all-cause death., Conclusions: Predictive models developed in a large diverse clinical trial with comprehensive clinical and laboratory baseline data-including novel measures-performed well in high-risk patients with HF who were receiving excellent guideline-based clinical care., Clinical Trial Registration: Clinicaltrials.gov identifier, NCT02861534.Lay Summary: Patients with heart failure may benefit from tools that help clinicians to better understand a patient's risk for future events like hospitalization. Relatively few risk models have been created after the worsening of heart failure in a contemporary cohort. We provide insights on the risk factors for clinical events from a recent, large, global trial of patients with worsening heart failure to help clinicians better understand and communicate prognosis and select treatment options., (Copyright © 2021 Elsevier Inc.

Importance: The period following heart failure hospitalization (HFH) is a vulnerable time with high rates of death or recurrent HFH., Objective: To evaluate clinical characteristics, outcomes, and treatment response to vericiguat according to prespecified index event subgroups and time from index HFH in the Vericiguat Global Study in Subjects With Heart Failure With Reduced Ejection Fraction (VICTORIA) trial., Design, Setting, and Participants: Analysis of an international, randomized, placebo-controlled trial. All VICTORIA patients had recent (<6 months) worsening HF (ejection fraction <45%). Index event subgroups were less than 3 months after HFH (n = 3378), 3 to 6 months after HFH (n = 871), and those requiring outpatient intravenous diuretic therapy only for worsening HF (without HFH) in the previous 3 months (n = 801). Data were analyzed between May 2, 2020, and May 9, 2020., Intervention: Vericiguat titrated to 10 mg daily vs placebo., Main Outcomes and Measures: The primary outcome was time to a composite of HFH or cardiovascular death; secondary outcomes were time to HFH, cardiovascular death, a composite of all-cause mortality or HFH, all-cause death, and total HFH., Results: Among 5050 patients in the VICTORIA trial, mean age was 67 years, 24% were women, 64% were White, 22% were Asian, and 5% were Black. Baseline characteristics were balanced between treatment arms within each subgroup. Over a median follow-up of 10.8 months, the primary event rates were 40.9, 29.6, and 23.4 events per 100 patient-years in the HFH at less than 3 months, HFH 3 to 6 months, and outpatient worsening subgroups, respectively. Compared with the outpatient worsening subgroup, the multivariable-adjusted relative risk of the primary outcome was higher in HFH less than 3 months (adjusted hazard ratio, 1.48; 95% CI, 1.27-1.73), with a time-dependent gradient of risk demonstrating that patients closest to their index HFH had the highest risk. Vericiguat was associated with reduced risk of the primary outcome overall and in all subgroups, without evidence of treatment heterogeneity. Similar results were evident for all-cause death and HFH. Addtionally, a continuous association between time from HFH and vericiguat treatment showed a trend toward greater benefit with longer duration since HFH. Safety events (symptomatic hypotension and syncope) were infrequent in all subgroups, with no difference between treatment arms., Conclusions and Relevance: Among patients with worsening chronic HF, those in closest proximity to their index HFH had the highest risk of cardiovascular death or HFH, irrespective of age or clinical risk factors. The benefit of vericiguat did not differ significantly across the spectrum of risk in worsening HF., Trial Registration: ClinicalTrials.gov Identifier: NCT02861534.

Background: The inflammatory cytokine IL-6 has been previously implicated in the pathophysiology of acute decompensated heart failure (HF). Prior observations in acute HF patients have suggested that IL-6 may be associated with outcomes and modulated by nesiritide. We aimed to evaluate the associations between serial IL-6 measurements, mortality and rehospitalization in acute HF., Methods and Results: We analyzed the associations between IL-6 in acute HF, readmission, and mortality (30 and 180 days) using a cohort of 883 hospitalized patients from the ASCEND-HF trial (nesiritide vs placebo). Plasma IL-6 was measured at randomization (baseline), 48-72 hours, and 30 days. The median IL-6 was highest at baseline (14.1 pg/mL) and decreased at subsequent time points (7.6 pg/mL at 30 days). In a univariable Cox regression analysis, the baseline IL-6 was associated with 30- and 180-day mortality (hazard ratio per log 1.74, 95% confidence interval 1.09-2.78, P = .021; hazard ratio 3.23, confidence interval 1.18-8.86, P = .022, respectively). However, there was no association after multivariable adjustment. IL-6 at 48-72 hours was found to be independently associated with 30-day mortality (hazard ratio 8.2, confidence interval 1.2-57.5, P= .03), but not 180-day mortality in multivariable analysis that included the ASCEND-HF risk model and amino terminal pro-B-type natriuretic peptide as covariates. In comparison with placebo, nesiritide therapy was not associated with differences in serial IL-6 levels., Conclusions: Although elevated IL-6 levels were associated with higher all-cause mortality in acute HF, no independent association with this outcome was identified at baseline or 30-day measurements. In contrast with prior reports, we did not observe any impact of nesiritide over placebo on serial IL-6 levels., (Copyright © 2021 Elsevier Inc. All rights reserved.)

Background: Prediction of outcomes in patients with heart failure (HF) may inform prognosis, clinical decisions regarding treatment selection, and new trial planning. The VICTORIA trial included high-risk patients with HF and reduced ejection fraction and a recent worsening HF event. The study participants had an unusually high event rate despite usage of contemporary guideline-based therapies. To provide generalizable predictive data for a broad population with a recent worsening HF event, we focused on risk prognostication in the placebo group., Methods: Data from 2524 participants randomized to placebo with chronic HF (New York Heart Association class [NYHA] II-IV) and ejection fraction <45% were studied and backward variable selection was used to create Cox proportional hazards models for clinical endpoints, selecting from 66 candidate predictors. Final model results were produced, accounting for missing data, non-linearities, and interactions with treatment. Optimism-corrected c-indices were calculated using 200 bootstrap samples., Results: During a median follow-up of 10.4 months, the primary outcome of HF hospitalization or cardiovascular death occurred in 972 (38.5%) patients. Independent predictors of increased risk for the primary endpoint included HF characteristics (longer HF duration and worse NYHA class), medical history (prior myocardial infarction), and laboratory values (higher N-terminal pro-hormone B-type natriuretic peptide, bilirubin, urate; lower chloride and albumin). Optimism-corrected c-indices were 0.68 for the HF hospitalization/cardiovascular death model, 0.68 for HF hospitalization/all-cause death, 0.72 for cardiovascular death, and 0.73 for all-cause death., Conclusions: Predictive models developed in a large diverse clinical trial with comprehensive clinical and laboratory baseline data-including novel measures-performed well in high-risk HF patients who were receiving excellent guideline-based clinical care., Clinical Trial Registration: Clinicaltrials.gov identifier, NCT02861534., Lay Summary: Patients with heart failure may benefit from tools that help clinicians better understand patient's risk for future events like hospitalization.

Background: Emerging evidence suggests that coronary intensive care units are evolving into intensive care environments with an increasing burden of non-cardiovascular illness, but previous studies have been limited to older populations or single center experiences., Methods: Canadian national health-care data was used to identify all patients ≥18 years admitted to dedicated coronary intensive care units (2005-2015) and admissions were categorized as primary cardiac or non-cardiac. The outcomes of interest included longitudinal trends in admission diagnoses, critical care therapies, and all-cause in-hospital mortality., Results: Among the 373,992 patients admitted to a coronary intensive care unit, minimal changes in the proportion of patients admitted with a primary cardiac (88.2% to 86.9%; p <0.001) and non-cardiac diagnoses (11.8% to 13.1%; p <0.001) were observed. Among cardiac admissions, a temporal increase in the proportion of ST-segment elevation myocardial infarction (19.4% to 24.1%, p <0.001), non-ST-segment elevation myocardial infarction (14.6% to 16.2%, p <0.001), heart failure (7.3% to 8.4%, p <0.001), shock (4.9% to 5.7%, p <0.001), and decline in unstable angina (4.9% to 4.0%, p <0.001) and stable coronary diseases (21.3% to 12.4%, p <0.001) was observed. The proportion of patients requiring critical care therapies (57.8% to 63.5%, p <0.001) including mechanical ventilation (9.6% to 13.1%, p <0.001) increased. In-hospital mortality rates for patients with primary cardiac (4.9% to 4.4%; adjusted odds ratio 0.71, 95% confidence interval 0.63-0.79) and non-cardiac (17.8% to 16.1%; adjusted odds ratio 0.84, 0.73-0.97) declined; results were consistent when stratified by academic vs community hospital, and by the presence of on-site percutaneous coronary intervention., Conclusion: In a national dataset we observed a changing case-mix among patients admitted to a coronary intensive care unit, though the proportion of patients with a primary cardiac diagnosis remained stable. There was an increase in clinical acuity highlighted by critical care therapies, but in-hospital mortality rates for both primary cardiac and non-cardiac conditions declined across all hospitals. Our findings confirm the changing coronary intensive care unit case-mix and have implications for future coronary intensive care unit training and staffing.
