Background: Most patients hospitalized for heart failure (HF) present with signs of congestion. Prognostic significance of clinical congestion may vary depending on left ventricular ejection fraction (LVEF). This study aims to investigate the prognostic impact of congestion across different LVEF categories.

Methods and results: Composite congestion scores (CCSs; 0-9) derived from the severity of edema, jugular venous pressure, and orthopnea, were analyzed on admission and at discharge in 3787 patients hospitalized for HF (LVEF ≥ 40%: n = 2347, LVEF < 40%: n = 1440). The median admission CCS was 4 in both LVEF strata (P = .64). Adjusted hazard ratios (HRs; 95% confidence interval [CI]) of the moderate (CCS 4-6) and severe congestion [7-9] groups relative to the mild congestion [0-3] group on admission for a composite of all-cause death or HF rehospitalization were 1.20 (1.04-1.39, P = .01) and 1.54 (1.27-1.86, P < .001) in the LVEF ≥ 40% stratum, and 1.20 (1.01-1.44, P = .04) and 0.82 (0.61-1.07, P = .14) in the LVEF < 40% stratum, respectively (P_interaction< .001). A total of 16% of the patients with LVEF ≥40% and 14% with LVEF <40% had residual congestion (CCS ≥ 1) at discharge, which was associated with a respective adjusted HR of 1.40 (1.18-1.65, P < .001) and 1.25 (0.98-1.58, P = .07) for postdischarge death or HF rehospitalization (P_interaction = 0.63).

Conclusion: The severity of clinical congestion on admission was associated with adverse clinical outcomes in patients with LVEF ≥ 40%, but not in those with LVEF < 40%. These findings warrant further studies to better understand the detailed profile of congestion across the LVEF spectrum.

Introduction: Women continue to remain under-represented in academic publishing in the field of cardiology. Some evidence suggests that double-blind peer reviews may mitigate the impact of gender bias. In July 2021, the Journal of Cardiac Failure implemented a process for the conduct of double-blind reviews after previously using single-blind reviews, with the aim of improving author diversity. The purpose of the current study was to examine the association between changes in authorship characteristics and implementation of double-blind reviews.

Methods: Manuscripts were stratified into 3 Eras: March-September 2021 (Era 1: prior to double-blind reviews); March-September 2022 (Era 2); and March-September 2023 (Era 3). All article types except invited editorials were included. Data were abstracted, including names, genders, ranks, and disciplines of the first and senior authors.

Results: A total of 310 manuscripts were included in the analysis. The proportion of women first authors increased from 24% in Era 1 to 34% in Era 2 to 39% in Era 3, while the percentage of women authors serving in a senior authorship role remained fairly stable over time-around 21%-22%. Even after adjusting for region, article type, first-author discipline, and last-author gender, there was an increase in female first authors over time (P = 0.015). Manuscripts with a female senior author were significantly more likely to have a female first author.

Conclusions: Our findings suggest that double-blind peer review may contribute to increased gender diversity of first authors and may highlight areas for future improvement by the Journal and academic publishing in general.

Background: The effect of steroids on congestion in patients with acute heart failure (AHF) is not known.

Methods and results: Patients with AHF, NT-proBNP levels > 1500 pg/mL and high-sensitivity C-reactive protein (hsCRP) levels > 20 mg/L were randomized to once-daily oral 40 mg prednisone for 7 days or usual care. In this post hoc analysis, congestion score was calculated on the basis of orthopnea, edema and rales (0 reflecting lack of congestion, and 9 maximal congestion) at each time point. Among 100 eligible patients randomized, those assigned to prednisone had a greater improvement in congestion score at day 31 (win odds for the prednisone group compared to usual care at day 31 was 1.77 (95% CI 1.17-2.84; P = 0.0066) in all patients and 2.41 (95% CI 1.37-5.05; P = 0.0016) in patients with IL-6 > 13 pg/mL at baseline. In patients with congestion scores ≥ 7 at baseline, the effects of prednisone therapy on the EQ-5D visual analog scale score were 4.30 (95% CI 0.77-7.83) points at day 7 and 5.40 (0.51-10.29) points at day 31, accompanied by lower heart rate and respiratory rate and higher oxygen saturation compared to usual care.

Conclusions: In patients with AHF and inflammatory activation, 7-day steroid therapy was associated with reduction in signs of congestion up to day 31. These results need confirmation in larger studies examining potential effects of steroids on congestion, diuresis, fluid redistribution and vascular permeability as well as clinical effects in AHF.

Background: A novel implantable sensor has been designed to measure the inferior vena cava (IVC) area accurately so as to allow daily monitoring of the IVC area and collapse to predict congestion in heart failure (HF).

Methods: A prospective, multicenter, single-arm, Early Feasibility Study enrolled 15 patients with HF (irrespective of ejection fraction) and with an HF event in the previous 12 months, an elevated NT-proBNP level, and receiving ≥ 40 mg of furosemide equivalent. Primary endpoints included successful deployment without procedure-related (30 days) or sensor-related complications (3 months) and successful data transmission to a secure database (3 months). Accuracy of sensor-derived IVC area, patient adherence, NYHA classification, and KCCQ were assessed from baseline to 3 months. Patient-specific signal alterations were correlated with clinical presentation to guide interventions.

Results: Fifteen patients underwent implantation: 66 ± 12 years; 47% female; 27% with HFpEF, NT-ProBNP levels 2569 (median, IQR: 1674-5187, ng/L; 87% NYHA class III). All patients met the primary safety and effectiveness endpoints. Sensor-derived IVC areas showed excellent agreement with concurrent computed tomography (R² = 0.99, mean absolute error = 11.15 mm²). Median adherence to daily readings was 98% (IQR: 86%-100%) per patient-month. A significant improvement was seen in NYHA class and a nonsignificant improvement was observed in KCCQ.

Conclusions: Implantation of a novel IVC sensor (FIRE1) was feasible, uncomplicated and safe. Sensor outputs aligned with clinical presentations and improvements in clinical outcomes. Future investigation to establish the IVC sensor remote management of HF is strongly warranted.

Background: A primary goal of treating patients with obstructive hypertrophic cardiomyopathy (oHCM) is to improve their symptoms, function and quality of life. Although the psychometric properties of the 23-item Kansas City Cardiomyopathy Questionnaire (KCCQ-23) have been described in oHCM, they have not been assessed for the shorter 12-item version (KCCQ-12), which is used increasingly in clinical practice.

Methods and results: Using data from the EXPLORER-HCM trial, the psychometric properties of the KCCQ-12 were evaluated. The KCCQ-12 domain and summary scores had moderate correlations with the most relevant clinical (New York Heart Association class, exercise duration, peak oxygen consumption) and patient-reported measures (EQ-5D-5L visual analog scale, Work Productivity and Activity Impairment [WPAI] questionnaire, and Hypertrophic Cardiomyopathy Symptom Questionnaire [HCMSQ]). KCCQ-12 domain scores had strong internal consistency, and test-retest reliability, demonstrated significant and proportional changes with differing magnitudes of clinical change (assessed by the patients' global impressions of change and the patients' impressions of severity), and they demonstrated close equivalence to the KCCQ-23 scores.

Conclusions: The KCCQ-12 demonstrated good psychometric performance for patients with oHCM, comparable to that of the KCCQ-23, supporting its use in clinical practice to care for patients with oHCM.
