Cellular Adhesion Molecules and Adverse Outcomes in Chronic Heart Failure: Findings From the DAPA-HF Randomized Clinical Trial.

IMPORTANCE: Vascular cell adhesion molecule 1 (VCAM-1) and intracellular cell adhesion molecule 1 (ICAM-1) are responsible for immune cell-cell interactions. Systemic levels of VCAM-1 are associated with incident heart failure (HF). OBJECTIVES: To determine if VCAM-1 and ICAM-1 levels are associated with progression of established HF. DESIGN, SETTING, AND PARTICIPANTS: Participants enrolled in the biomarker substudy of the Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure (DAPA-HF) randomized clinical trial had VCAM-1 and ICAM-1 levels measured at baseline and 12 months. The DAPA-HF trial was conducted at 410 sites in 20 countries. Patients with HF and reduced ejection fraction (HFrEF) in New York Heart Association (NYHA) class II to IV with elevated natriuretic peptides were enrolled between February 15, 2017, and August 17, 2018, with final follow-up on June 6, 2019. Data were analyzed from January 2023 to January 2025. INTERVENTIONS: Dapagliflozin, 10 mg, once daily vs placebo. MAIN OUTCOMES AND MEASURES: The primary outcome was the composite of a worsening HF event or cardiovascular death. The associations between VCAM-1 and ICAM-1 levels at baseline and the primary outcome, its components, and all-cause death were analyzed using Cox proportional hazards regression models adjusted for known prognostic variables including estimated glomerular filtration rate (eGFR), N-terminal pro-B-type natriuretic peptide (NT-proBNP), and high-sensitivity troponin T (hs-TnT), as well as high-sensitivity C-reactive protein. RESULTS: A total of 3051 participants (mean [SD] age, 67.2 [10.5] years; 2386 male [78.2%]) were included in this study. Mean (SD) follow-up time was 17.6 (5.2) months. The median (IQR) baseline VCAM-1 level was 997 (816.7-1218.8) ng/mL. Compared with patients with lower concentrations of VCAM-1, those with higher concentrations of VCAM-1 were older (mean [SD] age T3 vs T1, 69.7 [9.7] years vs 64.1 [10.7] years; P < .001), in worse NYHA class (T3 vs T1, NYHA class III/IV 35.6% [362 of 1017] vs 26.5% [269 of 1017]; P < .001), and had higher NT-proBNP (median [IQR] T3 vs T1, 2018 [1126-3753] pg/mL vs 1118 [693-1830] pg/mL) and hs-TnT (median [IQR] T3 vs T1, 24.7 [17.1-37.5] ng/L vs 16.6 [11.6-24.9] ng/L) concentrations, and lower eGFR (mean [SD] T3 vs T1, 58.4 [17.6] mL/min/1.73 m2 vs 71.7 [18.0] mL/min/1.73 m2). Patients in tertile 3 of VCAM-1, compared with tertile 1, had the highest risk of each outcome (eg, adjusted hazard ratio [HR] for primary outcome 1.40; 95% CI, 1.11-1.77; P = .004). ICAM-1 level was not associated with an elevated risk of any outcome. The benefit of dapagliflozin vs placebo in reducing the risk of the primary outcome was consistent across VCAM-1 tertiles: HR, 0.76 (95% CI, 0.54-1.06), 0.82 (95% CI, 0.59-1.12), and 0.77 (95% CI, 0.61-0.98) for tertiles 1, 2 and 3, respectively (P for interaction = .93). There was no significant change in VCAM-1 level with dapagliflozin at 52 weeks. CONCLUSIONS AND RELEVANCE: Results of this substudy of the DAPA-HF randomized clinical trial demonstrate that higher VCAM-1 levels, possibly reflecting a distinct inflammatory/immune pathophysiological pathway in HFrEF, were associated with worse outcomes, even after adjustment for conventional prognostic variables.

Finerenone According to Frailty in Heart Failure: A Prespecified Analysis of the FINEARTS-HF Randomized Clinical Trial.

IMPORTANCE: Patients with frailty are often perceived to have a less favorable benefit-risk profile for novel therapies and therefore may be less likely to receive these. OBJECTIVE: To examine the efficacy and safety of finerenone, compared with placebo, according to frailty status in patients with heart failure (HF) and mildly reduced ejection fraction (HFmrEF) or with HF and preserved ejection fraction (HFpEF). DESIGN, SETTING, AND PARTICIPANTS: This was a prespecified secondary analysis of a phase 3 randomized clinical trial, the Finerenone Trial to Investigate Efficacy and Safety Superior to Placebo in Patients With Heart Failure (FINEARTS-HF), conducted across 653 sites in 37 countries. Patients with HF with New York Heart Association functional class II through IV, a left ventricular ejection fraction of 40% or higher, evidence of structural heart disease, and elevated natriuretic peptide levels were randomized between September 2020 and January 2023. Data analysis was conducted from October 1 to November 30, 2024. INTERVENTION: Addition of once-daily finerenone or placebo to usual therapy. MAIN OUTCOMES AND MEASURES: The primary outcome was a composite of cardiovascular death and total worsening HF events. Frailty was measured using the Rockwood cumulative deficit approach. RESULTS: Of the 6001 patients randomized in FINEARTS-HF, a frailty index (FI) was calculable in 5952 patients (mean [SD] age, 72.0 [9.6] years; 3241 [54.4%] male). In total, 1588 patients (26.7%) had class I frailty (FI ≤0.210 [not frail]), 2141 (36.0%) had class II frailty (FI 0.211-0.310 [more frail]), and 2223 (37.3%) had class III frailty (FI ≥0.311 [most frail]). Compared with patients with class I frailty, those with class II and III frailty had a higher risk of the primary outcome (unadjusted rate ratio [RR], 1.88 [95% CI, 1.54-2.28] for class II and 3.86 [95% CI, 3.22-4.64] for class III). The effect of finerenone on the primary outcome did not vary significantly by frailty class (class I: RR, 1.07 [95% CI, 0.77-1.49]; class II: RR, 0.66 [95% CI, 0.52-0.83]; class III: RR, 0.91 [95% CI, 0.76-1.07]; P for interaction = .77). Frailty class did not modify the effects of finerenone on the components of the primary outcome, all-cause death, or improvement in the Kansas City Cardiomyopathy Questionnaire total symptom score. The effects of finerenone, compared with placebo, on experiencing hypotension, elevated creatinine level, hyperkalemia, or hypokalemia did not differ by frailty class. CONCLUSIONS AND RELEVANCE: In FINEARTS-HF, finerenone reduced the risk of total worsening HF events and cardiovascular death, and it improved symptoms; these effects were not modified by frailty status. In addition, the effects of finerenone on experiencing hypotension, elevated creatinine level, hyperkalemia, or hypokalemia did not differ by frailty status.

Finerenone and Atrial Fibrillation in Heart Failure: A Secondary Analysis of the FINEARTS-HF Randomized Clinical Trial.

IMPORTANCE: Heart failure (HF) with mildly reduced or preserved ejection fraction and atrial fibrillation (AF) are closely intertwined. OBJECTIVE: To examine the efficacy and safety of the nonsteroidal mineralocorticoid receptor antagonist finerenone in patients with HF with mildly reduced or preserved ejection fraction according to the absence or presence of AF and the type of AF (paroxysmal vs persistent or permanent). DESIGN, SETTING, AND PARTICIPANTS: Prespecified analyses were conducted in the Finerenone Trial to Investigate Efficacy and Safety Superior to Placebo in Patients With Heart Failure (FINEARTS-HF) randomized clinical trial. The trial was conducted across 653 sites in 37 countries. Participants were adults aged 40 years and older with symptomatic HF and left ventricular ejection fraction of 40% or greater, randomized between September 2020 and January 2023. Data analysis was conducted from September 1 to October 1, 2024. INTERVENTION: Finerenone (titrated to 20 mg or 40 mg) or placebo. MAIN OUTCOMES AND MEASURES: The primary outcome was the composite of total HF events and cardiovascular death. New-onset AF or atrial flutter (AFL) was a prespecified exploratory outcome. RESULTS: Among 5984 patients (mean [SD] age, 72.0 [9.6] years; 2724 [45.5%] female) with known AF status at baseline, 1384 (23.1%) had paroxysmal AF and 1886 (31.5%) had persistent or permanent AF. Patients with both types of AF were older and had worse HF status compared with those without AF (2714 patients [45.4%]). Both types of AF were associated with a higher unadjusted risk of the primary outcome compared with no AF (event rate per 100 person-years of follow-up, 20.3 [95% CI, 17.9-23.1] with paroxysmal AF, 19.8 [95% CI, 17.8-22.0] with persistent or permanent AF, and 11.9 [95% CI, 10.7-13.3] with no AF; rate ratio [RR], 1.62 [95% CI, 1.37-1.92] with paroxysmal AF and 1.66 [95% CI, 1.43-1.93] with persistent or permanent AF vs no AF); however, the associations were attenuated after adjustment for known prognostic variables. The benefit of finerenone on the primary outcome (overall RR, 0.84 [95% CI, 0.74-0.95]) was not modified by baseline AF status (RR, 0.80 [95% CI, 0.65-0.98] with no AF, 0.83 [95% CI, 0.65-1.06] with paroxysmal AF, and 0.85 [95% CI, 0.69-1.05] with persistent or permanent AF; P for interaction = .94). New-onset AF or AFL occurred in 6.5% of patients and was associated with a higher subsequent adjusted risk of the primary outcome (rate ratio, 3.65 [95% CI, 2.57-5.18]; P < .001). The subdistribution hazard ratio for new-onset AF or AFL among those receiving finerenone vs placebo was 0.77 (95% CI, 0.57-1.04; P = .09). CONCLUSIONS AND RELEVANCE: The efficacy of finerenone was consistent regardless of AF status. New-onset AF was associated with a substantially higher risk of subsequent outcomes.

Mode of Death in Patients With Heart Failure With Mildly Reduced or Preserved Ejection Fraction: The FINEARTS-HF Randomized Clinical Trial.

IMPORTANCE: The mode of death in patients with heart failure with mildly reduced ejection fraction (HFmrEF) or heart failure with preserved ejection fraction (HFpEF) remains poorly understood and may vary by EF. OBJECTIVE: To evaluate the mode of death according to EF and the treatment effect of finerenone on cause-specific mortality in patients with HFmrEF/HFpEF. DESIGN, SETTING, AND PARTICIPANTS: This was a prespecified secondary analysis of the Finerenone Trial to Investigate Efficacy and Safety Superior to Placebo in Patients With Heart Failure (FINEARTS-HF) randomized clinical trial, which evaluated clinical outcomes in 6001 patients with HF and EF greater than or equal to 40% randomly assigned to finerenone or placebo. The mode of death in relation to baseline EF categories (<50%, ≥50-<60%, and ≥60%) was examined, and the effect of randomized treatment on cause-specific death in Cox regression models was assessed. Data analysis was conducted between September 2024 and January 2025. INTERVENTIONS: Finerenone vs placebo. MAIN OUTCOMES AND MEASURES: Mode of death as centrally adjudicated by a clinical end points committee. RESULTS: Of 1013 patients (16.9%; median [IQR] age, 76 [69-82] years; 594 male [58.6%]) who died during median (IQR) follow-up of 32 (23-36) months, mode of death was ascribed to cardiovascular causes in 502 (49.6%), noncardiovascular causes in 368 (36.3%), and undetermined cause in 143 (14.1%). Of cardiovascular deaths, 215 (42.8%) were due to sudden death, 163 (32.4%) to HF, 48 (9.6%) to stroke, 25 (5.0%) to myocardial infarction, and 51 (10.2%) to other cardiovascular causes. The proportion of all-cause, cardiovascular, and sudden death was higher in those with EF less than 50%. The proportion of deaths related to HF was similar across EF categories, and the proportion of deaths due to myocardial infarction, stroke, and other cardiovascular causes was low regardless of EF. Randomization to finerenone did not significantly reduce death or cause-specific death compared with placebo in any EF category. CONCLUSIONS AND RELEVANCE: Among patients with HFmrEF/HFpEF in the FINEARTS-HF randomized clinical trial, higher proportions of cardiovascular and overall mortality in those with EF less than 50% were related principally to higher proportions of sudden death. A clear treatment effect of finerenone on cardiovascular or cause-specific mortality was not identified, although the trial was likely underpowered for these outcomes.

Finerenone in Heart Failure With Improved Ejection Fraction: The FINEARTS-HF Randomized Clinical Trial.

IMPORTANCE: Patients with chronic heart failure (HF) and left ventricular ejection fraction (LVEF) less than 40% who experience LVEF improvement to 40% or higher (HFimpEF) may still face residual risks. OBJECTIVE: To assess the clinical profiles, risk, and treatment response to finerenone in participants with HFimpEF. DESIGN, SETTING, AND PARTICIPANTS: A total of 6001 patients with HE, LVEF of 40% or higher, New York Heart Association class II to IV symptoms, and elevated natriuretic peptide levels, were enrolled between September 14, 2020, and January 10, 2023. Patients with a prior history of LVEF less than 40% were included. Data analysis was conducted between September 1 to December 10, 2024. INTERVENTION: Participants received finerenone (titrated to 20 mg or 40 mg) or placebo. MAIN OUTCOMES AND MEASURES: The primary end point was the composite of cardiovascular (CV) death and total (first and recurrent) worsening HF events. RESULTS: Of the 6001 participants (mean [SD] age, 72 [9.7], years; 3269 male [55%]), 273 (5%) had a prior LVEF less than 40%. Among those with a prior LVEF of less than 40%, the median recorded prior LVEF was 35% [IQR, 30%-37%], with a median improvement of 12% [IQR, 8%-17%]. Over a median follow-up of 2.6 years, those with a history of LVEF of less than 40% experienced higher rates of the primary outcome of a composite of CV death and worsening of HF events (21.4 per 100 patient-years vs 16.0 per 100 patient-years) than did those whose LVEF was consistently 40% or higher. After adjustment for clinically relevant covariates; however, this rate ratio (RR) was not statistically different (absolute RR, 1.13; 95% CI, 0.85-1.49, P = .39). The treatment effect of finerenone on the primary outcome was consistent among those with a history of LVEF less than 40% and those with LVEF that was consistently 40% or higher (P for interaction = .36). Owing to higher baseline risk, the absolute risk reduction was greater among those with HFimpEF (9.2 vs 2.5 per 100 patient-years). Patients with HFimpEF tended to develop more hypotension with finerenone treatment, but otherwise, the safety profile of finerenone was similar in patients with and without previous LVEF less than 40%. CONCLUSIONS AND RELEVANCE: In this prespecified analysis of a randomized clinical trial, patients with HFimpEF remained at high risk of CV events, underscoring the need for continued management despite LVEF improvement. The treatment benefits of finerenone observed among the overall population of patients with HF with preserved EF were consistent among patients with HFimpEF.

Finerenone for Heart Failure and Risk Estimated by the PREDICT-HFpEF Model: A Secondary Analysis of FINEARTS-HF.

IMPORTANCE: Patients with heart failure (HF) and mildly reduced ejection fraction (HFmrEF) or preserved ejection fraction (HFpEF) have a spectrum of risk, and the effect of therapies may vary by risk. OBJECTIVES: To validate the Prognostic Models for Mortality and Morbidity in HFpEF (PREDICT-HFpEF) in the phase 3 randomized clinical trial Finerenone Trial to Investigate Efficacy and Safety Superior to Placebo in Patients With Heart Failure (FINEARTS-HF) and to evaluate the effect of finerenone, compared with placebo, across the spectrum of risk in these patients. DESIGN, SETTING, AND PARTICIPANTS: The FINEARTS-HF trial was conducted across 653 sites in 37 countries. Participants were adults 40 years and older with symptomatic HF and left ventricular EF of 40% or greater randomized between September 2020 and January 2023. INTERVENTION: Finerenone (titrated to 20 mg or 40 mg) or placebo. MAIN OUTCOMES AND MEASURES: The 3 PREDICT-HFpEF risk scores for the composite outcome of cardiovascular death or HF hospitalization, cardiovascular death, and all-cause death, respectively, were calculated. Predicted risk was compared with observed outcomes. Model performance was assessed using the Harrell C statistic. The rates of the predicted outcomes (plus the composite of cardiovascular death and worsening HF events, which was the primary end point in the trial) were examined according to quintiles of risk score, as was the effect of finerenone according to risk quintiles. RESULTS: A total of 6001 patients (mean [SD] age, 72 [9.6] years; 3269 male [54.5%]) were randomized in the FINEARTS-HF trial. The C statistics for cardiovascular death or HF hospitalization, cardiovascular death, and all-cause death at 2 years were 0.71 (95% CI, 0.69-0.72), 0.68 (95% CI, 0.66-0.71), and 0.69 (95% CI, 0.67-0.71), respectively. The risk of the composite outcomes was approximately 8- to 10-fold higher in those in the highest compared with the lowest risk quintile. The relative risk reduction with finerenone compared with placebo was consistent across the spectrum of risk for all outcomes examined (eg, interaction P value for primary outcome = .24). CONCLUSIONS AND RELEVANCE: Results of the FINEARTS-HF randomized clinical trial demonstrate that the PREDICT-HFpEF models performed well in terms of calibration and discrimination. Baseline risk did not modify the benefit of finerenone. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT04435626.

Clinical Phenotype and Prognosis of Asymptomatic Patients With Transthyretin Cardiac Amyloid Infiltration.

IMPORTANCE: Patients with transthyretin (ATTR) cardiac amyloid infiltration are increasingly diagnosed at earlier disease stages with no heart failure (HF) symptoms and a wide range of cardiac amyloid infiltration. OBJECTIVE: To characterize the clinical phenotype and natural history of asymptomatic patients with ATTR cardiac amyloid infiltration. DESIGN, SETTING, AND PARTICIPANTS: This cohort study analyzed data of all patients at 12 international centers for amyloidosis from January 1, 2008, through December 31, 2023. Inclusion criteria were asymptomatic ATTR cardiac amyloid infiltration, defined as an absence of HF history, HF signs and symptoms, diuretic therapy, and plasma cell dyscrasia with evidence of myocardial uptake on bone scintigraphy. If plasma cell dyscrasia was present, histologic confirmation of ATTR amyloid was required. EXPOSURE: Asymptomatic ATTR cardiac amyloid infiltration. MAIN OUTCOMES AND MEASURES: The primary outcomes were all-cause and cardiovascular (CV) mortality. The secondary outcomes were unplanned HF hospitalization, unplanned CV-related hospitalization, and a composite outcome of CV mortality and HF hospitalization. RESULTS: The study comprised 485 patients with asymptomatic ATTR cardiac amyloid infiltration (mean [SD] age, 74.9 [9.9] years, 85.8% male, 112 [23.1%] with hereditary ATTR amyloidosis), with 369 (76.1%) having grade 2 or 3 and 116 (23.9%) having grade 1 cardiac uptake at baseline. Patients with grade 2 or 3 uptake exhibited significantly more cardiac functional and structural abnormalities vs patients with grade 1 uptake. At 3 years, compared with grade 1 uptake, patients with grade 2 or 3 uptake had greater development of HF (54.3% [95% CI, 47.7%-61.3%] vs 23.1% [95% CI, 14.8%-35.1%]), greater outpatient diuretic initiation and N-terminal pro-B-type natriuretic peptide progression (35.0% [95% CI, 28.0%-43.2%] vs 12.4% [95% CI, 6.3%-23.7%]), and greater HF hospitalization (8.7% [95% CI, 5.9%-12.9%] vs 0%) and unplanned CV hospitalization (20.0% [95% CI, 15.7%-25.3%] vs 4.3% [95% CI, 1.6%-11.3%]). Over a median follow-up of 37 months (IQR, 20-64 months), the all-cause death rate was similar between patients with grade 1 vs 2 and 3 uptake; however, those with grade 2 or 3 compared with grade 1 uptake had a significantly higher risk of CV mortality (unadjusted hazard ratio, 5.30; 95% CI, 1.92-14.65). CONCLUSIONS AND RELEVANCE: This study shows that asymptomatic ATTR cardiac amyloid infiltration encompasses a wide spectrum of disease severity, with patients with grade 2 or 3 cardiac uptake experiencing an increased rate of CV events and CV mortality and patients with grade 1 uptake experiencing a lower CV event rate and predominantly non-CV mortality. These findings support the use of disease-modifying treatments in asymptomatic patients with grade 2 or 3 uptake and highlight the need of large-scale studies to assess their role in grade 1 uptake.

Estimated Long-Term Benefits of Finerenone in Heart Failure: A Prespecified Secondary Analysis of the FINEARTS-HF Randomized Clinical Trial.

IMPORTANCE: People living with heart failure (HF) with mildly reduced or preserved ejection fraction have substantially curtailed life expectancy free from clinical events compared with their peers of comparable age. The nonsteroidal mineralocorticoid receptor antagonist, finerenone, was recently shown to reduce risks of cardiovascular events in this population over a median follow-up of 2.6 years; as patients with HF typically continue treatment beyond this time frame, estimating the potential long-term benefits of finerenone could inform shared clinical decision-making. OBJECTIVE: To estimate the projected long-term treatment effects of finerenone in patients with HF with mildly reduced or preserved ejection fraction if treated over a patient's lifetime. DESIGN, SETTING, AND PARTICIPANTS: Prespecified analyses were conducted of the FINEARTS-HF trial, a phase 3 randomized clinical trial conducted across 653 sites in 37 countries. Adults 40 years and older with symptomatic HF and left ventricular ejection fraction of 40% or greater were randomized from September 2020 to January 2023. Median (IQR) follow-up was 2.6 (1.9-3.0) years. INTERVENTIONS: Finerenone (titrated to either 20 mg or 40 mg) or placebo. MAIN OUTCOMES AND MEASURES: The primary composite outcome was time to cardiovascular death or worsening HF event. The long-term gains in survival free from a primary end point with finerenone were iteratively estimated with age-based Kaplan-Meier curves using age at randomization rather than time from randomization. Differences in areas under the survival curves between the finerenone and placebo arms represented event-free survival gains. RESULTS: Among 6001 participants (median [IQR] age, 73 [66-79] years; 3269 male [54.5%]), mean survival free from the primary end point for a 55-year-old participant was 13.6 years (95% CI, 11.9-15.2 years) with finerenone and 10.5 years (95% CI, 6.8-11.3 years) with placebo, representing a gain in event-free survival of 3.1 years (95% CI, 0.8-5.4 years; P = .007). Mean event-free survival for a 65-year-old participant was 11.0 years (95% CI, 10.1-11.9 years) with finerenone and 8.9 years (95% CI, 8.1-9.8 years) with placebo, representing a gain of 2.0 years (95% CI, 0.8-3.3 years; P = .001). Projected mean event-free survival was numerically greater with finerenone than with placebo for every starting age between 50 to 80 years. Lifetime gains in event-free survival were observed even among individuals already treated with a sodium-glucose cotransporter 2 inhibitor (65-year-old participant: 3.1 years; 95% CI, 0.1-6.0 years; P = .04). CONCLUSIONS AND RELEVANCE: In this prespecified secondary analysis of the FINEARTS-HF randomized clinical trial, long-term treatment with finerenone was estimated to extend event-free survival by up to 3 years among people with HF with mildly reduced or preserved ejection fraction.

Kidney Outcomes in Transthyretin Amyloid Cardiomyopathy.

IMPORTANCE: Transthyretin amyloid cardiomyopathy (ATTR-CM) is a progressive cardiomyopathy that commonly presents with concomitant chronic kidney disease. Chronic kidney dysfunction is associated with worse outcomes, but the prognostic value of changes in kidney function over time has yet to be defined. OBJECTIVE: To assess the prognostic importance of a decline in estimated glomerular filtration rate (eGFR) in a large cohort of patients with ATTR-CM. DESIGN, SETTING, AND PARTICIPANTS: This retrospective, observational, single-center cohort study evaluated patients diagnosed with ATTR-CM at the National Amyloidosis Centre (NAC) in the UK who underwent an eGFR baseline assessment and a follow-up assessment at 1 year between January 2000 and April 2024. Data analysis was performed in June 2024. MAIN OUTCOMES AND MEASURES: The primary outcome was the risk of all-cause mortality associated with decline in kidney function (defined as a decrease in eGFR >20%). RESULTS: Among 2001 patients, mean (SD) age was 75.5 (8.4) years, and 263 patients (13.1%) were female. The median (IQR) change in eGFR was -5 mlL/min/1.73 m2 (-12 to 1), and 481 patients (24.0%) experienced decline in kidney function. Patients who experienced decline in kidney function more often had the p.(V142I) genotype than patients with stable kidney function (99 [20.6%] vs 202 [13.3%]; P < .001) and had a more severe cardiac phenotype at baseline, as evidenced by higher median (IQR) concentrations of serum cardiac biomarkers (N-terminal pro-B-type natriuretic peptide [NT-proBNP]: 2949 pg/mL [1759-5182] vs 2309 pg/mL [1146-4290]; P < .001; troponin T: 0.060 ng/mL [0.042-0.086] vs 0.052 ng/mL [0.033-0.074]; P < .001), while baseline median (IQR) kidney function was similar between the 2 groups (eGFR: 63 mL/min/1.73 m2 [51-77] vs 61 mL/min/1.73 m2 [49-77]; P = .41). Decline in kidney function was associated with a 1.7-fold higher risk of mortality (hazard ratio [HR], 1.71; 95% CI, 1.43-2.04; P < .001), with a similar risk across the 3 genotypes (wild type: HR, 1.64; 95% CI, 1.31-2.04; p.(V142I): HR, 1.70; 95% CI, 1.21-2.39; non-p.(V142I): HR, 1.51; 95% CI, 0.87-2.61) (P for interaction = .93) and the 3 NAC disease stages (stage 1: HR, 1.69; 95% CI, 1.22-2.32; stage 2: HR, 1.69; 95% CI, 1.30-2.18; stage 3: HR, 1.61; 95% CI, 1.11-2.35) (P for interaction = .97). Decline in kidney function remained independently associated with mortality after adjusting for increases in NT-proBNP and outpatient diuretic intensification (HR, 1.48; 95% CI, 1.23-2.76; P < .001). CONCLUSIONS AND RELEVANCE: In this retrospective cohort study, decline in kidney function was frequent in patients with ATTR-CM and was consistently associated with an increased risk of mortality, even after adjusting for established markers of worsening ATTR-CM. eGFR decline represents an independent marker of ATTR-CM disease progression that could guide treatment optimization in clinical practice.

Effects of Sacubitril/Valsartan on All-Cause Hospitalizations in Heart Failure: Post Hoc Analysis of the PARADIGM-HF and PARAGON-HF Randomized Clinical Trials.

IMPORTANCE: Sacubitril/valsartan is indicated to reduce the risk of cardiovascular death and heart failure (HF) hospitalizations in patients with chronic HF. However, many of these patients are older and have multiple comorbidities that increase the risk of hospitalization for causes other than HF. OBJECTIVE: To assess the effects of sacubitril/valsartan on hospitalizations of any cause across the spectrum of left ventricular ejection fraction (LVEF). DESIGN, SETTING, AND PARTICIPANTS: This post hoc, participant-level, pooled analysis of the PARADIGM-HF (in patients with an LVEF ≤40%) and PARAGON-HF (in patients with an LVEF ≥45%) randomized clinical trials was conducted from February 5, 2024, to April 5, 2024. Participants with chronic HF, New York Heart Association classes II through IV symptoms, and elevated natriuretic peptides were randomized to treatment with either sacubitril/valsartan or a renin-angiotensin system inhibitor (RASi)-enalapril in the PARADIGM-HF trial or valsartan in the PARAGON-HF trial. INTERVENTION: Sacubitril/valsartan vs RASi (enalapril or valsartan). MAIN OUTCOMES AND MEASURES: The effects of sacubitril/valsartan on time to first investigator-reported all-cause and cause-specific hospitalizations were examined using Cox proportional hazards models, stratified by geographic region and trial. Effect modification by LVEF as a continuous function was examined. RESULTS: Among 13 194 participants in the PARADIGM-HF and PARAGON-HF trials, mean (SD) patient age was 67 (11) years, 8883 patients (67.3%) were male, and mean (SD) LVEF was 40% (15%). Sacubitril/valsartan significantly reduced the risk of all-cause hospitalization (ACH) compared with RASi over a median (IQR) follow-up period of 2.5 (1.8-3.1) years (hazard ratio [HR], 0.92; 95% CI, 0.88-0.97; P = .002). The incidence rate of first ACH was 25 (95% CI, 24-26) per 100 patient-years in the sacubitril/valsartan arm and 27 (95% CI, 26-28) per 100 patient-years in the RASi arm. The absolute risk reduction (ARR) was 2.1 per 100 patient-years, corresponding to a number needed to treat (NNT) of 48 patient-years of treatment exposure to prevent 1 ACH. Reductions in overall hospitalizations seemed primarily driven by lower rates of cardiac and pulmonary hospitalizations with sacubitril/valsartan. Patients in the 2 treatment arms had similar rates of composite noncardiac hospitalizations. Treatment heterogeneity on ACH by LVEF was observed (P for interaction = .03), with benefits most apparent in patients with an LVEF less than 60% (HR, 0.91; 95% CI, 0.86-0.96), but not in patients with an LVEF of 60% or more (HR, 0.97; 95% CI, 0.86-1.09). CONCLUSIONS AND RELEVANCE: In this post hoc pooled analysis of 13 194 patients with chronic HF in the PARADIGM-HF and PARAGON-HF randomized clinical trials, sacubitril/valsartan significantly reduced hospitalization for any reason, with benefits most apparent in patients with an LVEF below normal. This reduction appeared to be principally driven by lower rates of cardiac and pulmonary hospitalizations.

Aficamten and Cardiopulmonary Exercise Test Performance: A Substudy of the SEQUOIA-HCM Randomized Clinical Trial.

IMPORTANCE: Impaired exercise capacity is a cardinal manifestation of obstructive hypertrophic cardiomyopathy (HCM). The Phase 3 Trial to Evaluate the Efficacy and Safety of Aficamten Compared to Placebo in Adults With Symptomatic Obstructive HCM (SEQUOIA-HCM) is a pivotal study characterizing the treatment effect of aficamten, a next-in-class cardiac myosin inhibitor, on a comprehensive set of exercise performance and clinical measures. OBJECTIVE: To evaluate the effect of aficamten on exercise performance using cardiopulmonary exercise testing with a novel integrated measure of maximal and submaximal exercise performance and evaluate other exercise measures and clinical correlates. DESIGN, SETTING, AND PARTICIPANTS: This was a prespecified analysis from SEQUOIA-HCM, a double-blind, placebo-controlled, randomized clinical trial. Patients were recruited from 101 sites in 14 countries (North America, Europe, Israel, and China). Individuals with symptomatic obstructive HCM with objective exertional intolerance (peak oxygen uptake [pVO2] ≤90% predicted) were included in the analysis. Data were analyzed from January to March 2024. INTERVENTIONS: Randomized 1:1 to aficamten (5-20 mg daily) or matching placebo for 24 weeks. MAIN OUTCOMES AND MEASURES: The primary outcome was change from baseline to week 24 in integrated exercise performance, defined as the 2-component z score of pVO2 and ventilatory efficiency throughout exercise (minute ventilation [VE]/carbon dioxide output [VCO2] slope). Response rates for achieving clinically meaningful thresholds for change in pVO2 and correlations with clinical measures of treatment effect (health status, echocardiographic/cardiac biomarkers) were also assessed. RESULTS: Among 282 randomized patients (mean [SD] age, 59.1 [12.9] years; 115 female [40.8%], 167 male [59.2%]), 263 (93.3%) had core laboratory-validated exercise testing at baseline and week 24. Integrated composite exercise performance improved in the aficamten group (mean [SD] z score, 0.17 [0.51]) from baseline to week 24, whereas the placebo group deteriorated (mean [SD] z score, -0.19 [0.45]), yielding a placebo-corrected improvement of 0.35 (95% CI, 0.25-0.46; P <.001). Further, aficamten treatment demonstrated significant improvements in total workload, circulatory power, exercise duration, heart rate reserve, peak heart rate, ventilatory efficiency, ventilatory power, and anaerobic threshold (all P <.001). In the aficamten group, large improvements (≥3.0 mL/kg per minute) in pVO2 were more common than large reductions (32% and 2%, respectively) compared with placebo (16% and 11%, respectively). Improvements in both components of the primary outcome, pVO2 and VE/VCO2 slope throughout exercise, were significantly correlated with improvements in symptom burden and hemodynamics (all P <.05). CONCLUSIONS AND RELEVANCE: This prespecified analysis of the SEQUOIA-HCM randomized clinical trial found that aficamten treatment improved a broad range of exercise performance measures. These findings offer valuable insight into the therapeutic effects of aficamten. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT05186818.

Estimated Lifetime Cardiovascular, Kidney, and Mortality Benefits of Combination Treatment With SGLT2 Inhibitors, GLP-1 Receptor Agonists, and Nonsteroidal MRA Compared With Conventional Care in Patients With Type 2 Diabetes and Albuminuria.

BACKGROUND: Sodium glucose cotransporter 2 inhibitors (SGLT2i), glucagon-like peptide-1 receptor agonists (GLP-1 RA), and the nonsteroidal mineralocorticoid receptor antagonist (ns-MRA) finerenone all individually reduce cardiovascular, kidney, and mortality outcomes in patients with type 2 diabetes and albuminuria. However, the lifetime benefits of combination therapy with these medicines are not known. METHODS: We used data from 2 SGLT2i trials (CANVAS [Canagliflozin Cardiovascular Assessment] and CREDENCE [Canagliflozin and Renal Events in Diabetes with Established Nephropathy Clinical Evaluation]), 2 ns-MRA trials (FIDELIO-DKD [Finerenone in Reducing Kidney Failure and Disease Progression in Diabetic Kidney Disease] and FIGARO-DKD [Efficacy and Safety of Finerenone in Subjects With Type 2 Diabetes Mellitus and the Clinical Diagnosis of Diabetic Kidney Disease]), and 8 GLP-1 RA trials to estimate the relative effects of combination therapy versus conventional care (renin-angiotensin system blockade and traditional risk factor control) on cardiovascular, kidney, and mortality outcomes. Using actuarial methods, we then estimated absolute risk reductions with combination SGLT2i, GLP-1 RA, and ns-MRA in patients with type 2 diabetes and at least moderately increased albuminuria (urinary albumin:creatinine ratio ≥30 mg/g) by applying estimated combination treatment effects to participants receiving conventional care in CANVAS and CREDENCE. RESULTS: Compared with conventional care, the combination of SGLT2i, GLP-1 RA, and ns-MRA was associated with a hazard ratio of 0.65 (95% CI, 0.55-0.76) for major adverse cardiovascular events (nonfatal myocardial infarction, nonfatal stroke, or cardiovascular death). The corresponding estimated absolute risk reduction over 3 years was 4.4% (95% CI, 3.0-5.7), with a number needed to treat of 23 (95% CI, 18-33). For a 50-year-old patient commencing combination therapy, estimated major adverse cardiovascular event-free survival was 21.1 years compared with 17.9 years for conventional care (3.2 years gained [95% CI, 2.1-4.3]). There were also projected gains in survival free from hospitalized heart failure (3.2 years [95% CI, 2.4-4.0]), chronic kidney disease progression (5.5 years [95% CI, 4.0-6.7]), cardiovascular death (2.2 years [95% CI, 1.2-3.0]), and all-cause death (2.4 years [95% CI, 1.4-3.4]). Attenuated but clinically relevant gains in event-free survival were observed in analyses assuming 50% additive effects of combination therapy, including for major adverse cardiovascular events (2.4 years [95% CI, 1.1-3.5]), chronic kidney disease progression (4.5 years [95% CI, 2.8-5.9]), and all-cause death (1.8 years [95% CI, 0.7-2.8]). CONCLUSIONS: In patients with type 2 diabetes and at least moderately increased albuminuria, combination treatment of SGLT2i, GLP-1 RA, and ns-MRA has the potential to afford relevant gains in cardiovascular and kidney event-free and overall survival.
