Background
Patients with chronic kidney disease, particularly those diagnosed with end-stage renal disease (ESRD), face an elevated risk of adverse outcomes, especially during cardiac procedures. However, the impact of ESRD on outcomes in patients with heart failure undergoing left ventricular assist device (LVAD) implantation remains underexplored.
Methods
Utilizing the 2016-2020 Nationwide Readmission Database, we analyzed data to evaluate heart failure patients who underwent LVAD implantation. Outcomes were compared between individuals with and without ESRD. The primary endpoint was inpatient mortality. Secondary endpoints included 90-day all-cause readmission rates, incidence of cardiogenic shock, length of stay (LOS), and total hospitalization charges (THC). Multivariate linear and logistic regression models were applied to account for confounders.
Results
Among 4,920 heart failure patients receiving an LVAD, 2.4% were identified as having ESRD. The presence of ESRD was associated with significantly higher odds of inpatient mortality (adjusted odds ratio [aOR] 1.91, 95% confidence interval [CI] 1.05-3.5), extended LOS (73 days vs. 33 days, p < 0.001), and increased THC ($1,873,835 vs. $896,426, p < 0.001) compared to non-ESRD patients. No significant differences were observed in 90-day all-cause readmission rates (aOR 1.61, 95% CI 0.74-3.5) or rates of cardiogenic shock (aOR 2.84, 95% CI 0.88-9.1) between the two groups.
Conclusion
In heart failure patients undergoing LVAD placement, the presence of ESRD was linked to heightened inpatient mortality, prolonged hospital stays, and greater healthcare costs, underscoring the need for tailored interventions to improve outcomes in this vulnerable population.
背景:慢性肾脏疾病患者,特别是那些被诊断为终末期肾脏疾病(ESRD)的患者,面临着不良后果的风险增加,特别是在心脏手术期间。然而,ESRD对接受左心室辅助装置(LVAD)植入的心力衰竭患者预后的影响仍未得到充分研究。方法利用2016-2020年全国再入院数据库,对行LVAD植入的心力衰竭患者进行数据分析。比较了有和没有ESRD的个体之间的结果。主要终点是住院病人死亡率。次要终点包括90天全因再入院率、心源性休克发生率、住院时间(LOS)和总住院费用(THC)。应用多元线性和逻辑回归模型来解释混杂因素。结果在4920名接受LVAD的心力衰竭患者中,2.4%被确定为ESRD。与非ESRD患者相比,ESRD的存在与住院死亡率(校正优势比[aOR] 1.91, 95%可信区间[CI] 1.05-3.5)、延长的LOS(73天对33天,p < 0.001)和增加的THC(1,873,835美元对896,426美元,p < 0.001)相关。两组90天全因再入院率(aOR 1.61, 95% CI 0.74-3.5)或心源性休克率(aOR 2.84, 95% CI 0.88-9.1)无显著差异。结论:在接受LVAD植入的心力衰竭患者中,ESRD的存在与住院死亡率升高、住院时间延长和医疗费用增加有关,因此需要针对性的干预措施来改善这一弱势人群的预后。

Purpose
The effect of pulmonary hemodynamics on outcomes after the implantation of the HeartMate 3 left ventricular assist device (HM3-LVAD) is still not fully understood, although some studies indicate positive results. We conducted an analysis using the EUROMACS international database, which includes many patients from various sites across Europe.
Methods
We identified adults who underwent HM3-LVAD implantation from the EUROMACS Database of the European Association of Cardiothoracic Surgery from January 2018 through April 2024. We excluded those with previous cardiac surgery, undergoing concomitant cardiac procedures, on an IABP or ECMO, and those with missing hemodynamic data. Based on the pre-transplant hemodynamic profile, patients were categorized into: Group 1 with a mean pulmonary artery PA pressure (mPAP) < 20 mmHg and a pulmonary vascular resistance (PVR) < 2 WU; Group 2 with a mPAP > 20 mmHg and a PVR < 2 WU; and Group 3 with a PVR > 2 WU. We compared 1- and 2-year mortality rates, major bleeding, and right ventricular (RV) failure after adjusting for factors in the HM3 Survival Risk Score.
Results
632 individuals were identified: 47 (7.4%) in group 1, 144 (22.8%) in group 2, and 441 (69.8%) in group 3. Groups differed in age, gender, body mass index, race, and pre-LVAD use of some medications. Post-implant 1-year and 2-year death rates were 14.1% (n=89) and 18.7% (n=118), respectively while 16.0% (n=103) experienced a major bleed. After adjusting for factors in the HM3 Risk Score, no differences were seen in the odds of 1-year death when group 1 (Odds Ratio [OR] 1.09, 95% confidence interval [CI] 0.46-2.59) and group 2 (OR 0.61, 95% CI 0.61-1.86) were compared with group 3 (Figure). Similar results were seen for 2-year mortality (group 1 vs. group 3, p = 0.561; group 2 vs group 3, p = 0.330) and major bleeding (group 1 vs. group 3, p = 0.476; group 2 vs group 3, p = 0.958) with no difference between the groups. While, compared with group 3, group 1 increased the odds of late (>14 days) RV failure, no other differences in late or early (14 days) failure were seen.
Conclusions
In this retrospective study, elevated PA pressure and/or resistance did not affect the mortality and bleeding rates up to 2 years after HM3-LVAD implantation in adults enrolled in the EUROMACS database.

Heart transplantation remains the gold standard for the treatment of end-stage heart failure, with continuous advancements in surgical techniques and post-transplant care. However, the burden of heart transplant hospitalizations, including associated mortality rates, length of stay, and hospitalization costs, remains a critical area of study. Understanding these trends over time can provide valuable insights into the evolving landscape of heart transplant care in the United States.
Objective
The objective of this study is to assess the trends in the incidence, mortality, hospitalization cost, and length of stay for heart transplant admissions in the United States from 2016 to 2022.
Methods
In this descriptive study, we utilized data from the National Inpatient Sample (NIS) spanning from 2016 to 2022. We included patients who underwent heart transplants, identified through ICD-10 PCS codes. Quarterly trends were assessed for the mean number of transplants, the mean mortality rate, the median length of hospital stay (in days), and the median cost of hospitalization (in USD). The cost of hospitalization was adjusted for inflation using the corresponding average quarterly consumer price indices provided by the United States Bureau of Labor Statistics.
Results
A total of 20,905 heart transplant-related admissions were recorded over the study period. The mean age of the study population was 49.1 years (SD = 19.4), with 70.8% of the patients being male. The racial and ethnic composition was 58% White, 22% Black, and 11.5% Hispanic. Additionally, 99.4% of the admissions occurred at urban teaching hospitals. The annual number of heart transplants showed a modest increase, rising from 2,701 in 2016 to 3,361 in 2022. The annual mortality rate, however, remained relatively stable across the study period. The median hospitalization cost significantly increased from $670,147 (IQR = $761,238) in 2016 to $1,156,591 (IQR = $1,149,662) in 2022. The length of hospital stay also exhibited a steady upward trend, with a median of 25 days (IQR = 40) in 2016, increasing to 37 days (IQR = 40) in 2022.
Conclusions
Our analysis reveals a steady increase in heart transplant hospitalizations, with a notable rise in hospitalization costs and LOS, while the mortality rate remains stable.

Background
Environmental factors and housing instability (HI) may affect heart failure (HF) readmissions, which are a substantial clinical and economic burden. National prediction models attempt to address this issue, but they often ignore local factors like social drivers of health (SDOH). Standardized models rarely account for how housing instability affects medication adherence, post-discharge care, and HF treatment.
Hypothesis
We tested whether adding an extended definition of the HI variable and the Environmental Justice Index (EJI) to machine learning (ML)-based prediction models improves 30-, 60-, and 90-day HF readmission estimates at a large urban safety-net hospital. We expected that locally calibrated SDOH-integrated models would outperform clinical variable-based techniques.
Methods
This retrospective cohort analysis included 5,989 persons hospitalized with HF at Grady Memorial Hospital in Atlanta, GA, between January 2018 and December 2021. Comparing a Traditional Clinical Model (TCM) to an “expanded” Social Determinants Model (SDM) with HI status defined as having had HI within the past twelve months vs. the categorical definition of the TCM on admission. Logistic Regression, Random Forest, XGBoost, Neural Network, and SVM trained (70%) and validated (30%) to predict HF readmissions across 30, 60, and 90 days. Area under the ROC curve (AUC), accuracy, sensitivity, specificity, Brier score, and related metrics examined model discrimination and calibration.
Results
HI patients (10.5% of the cohort) showed higher readmission rates (32.96% vs. 12.33% at 30 days, 46.34% vs. 20.52% at 90 days; p<0.001). At all-time points, ML models with HI and the EJI demonstrated higher discriminative capacity over traditional models, with lower Brier’s score (XGBoost 0.7788 at 90 days). Ensemble-based approaches (Random Forest, XGBoost) of the SDM outperformed logistic regression and SVM, showing the predictive power of local SDOH variables and the extent of variable definition.
Conclusions
Extending the definition of HI to challenges up to twelve months and integrating the EJI enhanced HF readmission in an urban safety-net hospital. ML models' discrimination of 30-, 60-, and 90-day outcomes increased with local social context, highlighting the value of institution-specific SDOH data. This personalized approach could reduce HF readmissions, especially in vulnerable populations.

Background
Pulmonary arterial hypertension (PAH) remains a progressive disease with high morbidity despite therapeutic advances. While guidelines recommend combination therapy, data comparing soluble guanylate cyclase stimulators (sGCs) alone versus in combination with endothelin receptor antagonists (ERAs) are limited.
Methods
Using the TriNetX Research Network, we conducted a propensity score-matched cohort study of PAH patients receiving either sGC monotherapy (riociguat/vericiguat) or sGC+ERA combination therapy (with bosentan/ambrisentan/macitentan) between 2015-2023. After 1:1 propensity matching (n=1,267 per group), we compared 5-year outcomes including mortality, major adverse cardiac events (MACE), and other clinical endpoints.
Results
The sGC+ERA group demonstrated significantly higher MACE incidence (7.3% vs 4.5%; p=0.005) and lower MACE-free survival rates (86.5% vs 91.6%). All-cause mortality appeared higher in the combination therapy group (27.0% vs 22.7%, p=0.013), but this difference was not significant in time-to-event analysis. The combination therapy group showed higher rates of BNP elevation (HR: 1.36, p=0.047) and hypotension (HR: 1.30, p=0.010). However, after accounting for competing risks, mortality differences diminished (23.8% vs 21.9%, p=0.319). Multivariable Cox regression revealed a protective effect of combination therapy (adjusted HR: 0.85, p=0.022) after controlling for demographics, comorbidities, and clinical parameters.
Conclusions
In this real-world analysis, sGC+ERA combination therapy was associated with higher risks of MACE and hypotension compared to sGC monotherapy. However, after accounting for competing risks and patient characteristics, combination therapy showed potential mortality benefits. These findings emphasize the complex risk-benefit profile of combination therapy and underscore the importance of individualized treatment approaches in PAH management, with careful consideration of patient-specific factors to optimize outcomes.
背景肺动脉高压(PAH)仍然是一种进行性疾病,尽管治疗取得了进展,但发病率很高。虽然指南推荐联合治疗,但比较单独使用可溶性鸟苷酸环化酶刺激剂(sGCs)与联合使用内皮素受体拮抗剂(ERAs)的数据有限。方法使用TriNetX研究网络,我们对2015-2023年间接受sGC单药治疗(瑞西奎特/维西奎特)或sGC+ERA联合治疗(波生坦/安布里森坦/马西坦)的PAH患者进行了倾向评分匹配队列研究。在1:1倾向匹配(n= 1267 /组)后,我们比较了5年结局,包括死亡率、主要不良心脏事件(MACE)和其他临床终点。结果sGC+ERA组MACE发生率显著高于对照组(7.3% vs 4.5%; p=0.005),无MACE生存率显著低于对照组(86.5% vs 91.6%)。联合治疗组的全因死亡率更高(27.0% vs 22.7%, p=0.013),但在时间-事件分析中差异不显著。联合治疗组BNP升高(HR: 1.36, p=0.047)和低血压(HR: 1.30, p=0.010)发生率较高。然而,在考虑竞争风险后,死亡率差异减小(23.8% vs 21.9%, p=0.319)。在控制了人口统计学、合并症和临床参数后,多变量Cox回归显示了联合治疗的保护作用(校正HR: 0.85, p=0.022)。结论在现实世界的分析中,sGC+ERA联合治疗与sGC单药治疗相比,MACE和低血压的风险更高。然而,在考虑了竞争风险和患者特征后,联合治疗显示出潜在的死亡率优势。这些发现强调了联合治疗的复杂风险-收益概况,并强调了个性化治疗方法在PAH管理中的重要性,并仔细考虑患者特异性因素以优化结果。

Introduction
Pulmonary Artery Pressure Monitoring has been shown to reduce rehospitalization in HF patients. Interatrial Shunting (IS) is in clinical studies for similar purposes. However, none of the currently available devices provide both at the same time.
Hypothesis
A novel implantable system has been developed to provide IS and LAP monitoring. It consists of an implant device, a delivery system, and an external Monitoring Unit (MU). The MU works with the device’s MEMS pressure sensor to provide the measured LAP. This study aims to assess the feasibility of the system and accuracy of measured LAP in a chronic canine study.
Methods
The device was implanted in 10 healthy dogs (Labrador, 30-35 Kg), with 4 observed for 1 month and 6 for 3 months. Procedure success, safety outcome, shunt patency (via TEE) and pressure accuracy were evaluated. To achieve various pressure levels, phenylephrine (0.05-2.00 mg) was injected during implant and at the end of each follow up (FU) before termination. Waveforms of PCWP from Swan Ganz and LAP from the device were recorded for more than 10 seconds by PowerLab (PLC01) and MU respectively. Correlation and agreement between LAP and PCWP were assessed with Pearson’s correlation analysis and Bland-Altman plots.
Results
The implant was successful in all dogs with shunt patent at 1 or 3 months. No device related adverse event was observed. Pressure points were obtained for each dog, with a total of 42 pairs of pressure measurements ranging from 0 to 22 mmHg from all dogs. Fig. 1a shows an example of the device encapsulation by a thin layer of endothelium at 3 months. Simultaneous pressure waveform recordings, correlation and Bland-Altman plot are shown in Fig.1b-d. The PCWP and LAP measurements correlated well (R2=0.87), with an average difference of 0.33±1.80 mmHg. In the Bland-Altman plot, 40 of 42 pairs fell inside the 95% limit of agreement, indicating good agreement between PCWP measured by Swan-Ganz and LAP by the device.
Conclusions
This preliminary chronic animal study demonstrated the feasibility of this implantable device and the accuracy of device-based LAP as compared to PCWP. Further studies are warranted. This novel device with interatrial shunting therapy and hemodynamic monitoring has the potential to provide clinicians with more options for managing HF patients.

Background
Heart Failure (HF) and Pulmonary Embolism (PE)-related mortality rates are increasing annually in the United States. This study aims to analyze mortality trends of HF and PE-related deaths in the adult population of the United States (1999-2000).
Methods
The study analyzed HF and PE-related mortality rates from 1999 to 2020 using death certificate data from the Centers for Disease Control and Prevention Wide-Ranging OnLine Data for Epidemiologic Research (CDC WONDER). The Age-Adjusted Mortality Rates (AAMR), per 100 000 people, Annual Percent Changes (APCs) and corresponding Confidence Intervals (CIs) were calculated. Data was further stratified by year, sex, race, and geographic region (state and census regions).
Results
This study examines 60,072 deaths related to HF and PE among U.S. adults aged 25-85+ years from 1999 to 2020. The age-adjusted mortality rate (AAMR) increased from 1.1 (95% CI: 1.05-1.15) in 1999 to 1.88 (95% CI: 1.83-1.93) in 2020, with a particularly sharp rise from 2018 to 2020 with an APC of 12.14%. The total number of deaths increased from 1,980 in 1999 to a peak of 5,026 in 2020. Mortality was higher among females accounting for 56.07% than males with just 43.93% of total deaths, although men exhibited higher AAMRs 1.35 than that of females of 1.2, AAMRs among men increased from 1.15 in 1999 to 2.14 in 2020 with an APC of 7.21%, while females' AAMR had a significant rise from 1.3 in 2018 to 1.66 in 2020 having an APC of 12.16%. Racial disparities were evident, with non-Hispanic Black individuals having the highest AAMR of 2.10, followed by non-Hispanic Whites with AAMR of 1.24, non-Hispanic American Indian or Alaska Natives had AAMR of 1.13, Hispanics with 0.41 AAMR, and non-Hispanic Asian or Pacific Islanders had an AAMR of 0.38 The AAMR for non-Hispanic Black individuals rose significantly after 2016 all the way to 2020 with a staggering APC of 11.48%. Geographic differences were also notable, with the Southern region accounting for the highest proportion of deaths,37.50% of the total deaths where Wyoming recorded the highest AAMR of 2.05, while Hawaii had the lowest of 0.65. States like Texas and California contributed the highest total deaths with an AAMR of 1.55 and AAMR of 1.12 respectively.
Conclusion
Heart failure and pulmonary embolism-related AAMR inclined in the US from 1999 to 2020, with an obvious rise seen in the last year of our study period. This trend was seen more in men, NH black Africans, and southern regions of the country. Further prospective research with larger sample sizes and controlling for potential confounding factors is critical to better elucidate these correlations.

The increasing prevalence of cardiometabolic diseases which, via insulin resistance, cellular apoptosis, and myocardial fibrosis, lead to heart failure with preserved ejection fraction.
Hypothesis
Our novel bispecific biologic (CRRL 101) mitigates these processes by targeting both the GLP-1 and GCA pathways.
Methods
We evaluated CRRL 101 (10 µM) in vitro using transfected human embryonic kidney (HEK) cells, INS-1 rat pancreatic beta cells, human cardiac fibroblasts (HCF), AC16 human cardiomyocytes, and human preadipocytes-visceral(HPA-vis). Data was analyzed using GraphPad Prism 9.4.1 and are presented as mean ± SEM.
Results
In HEK cells, CRRL 101 markedly increased cyclic guanosine monophosphate (cGMP) levels (8.9 pmol/mL ± 5.1 vs 457.2 pmol/mL ± 64.9 relative activity 100) in GCA-expressing HEK, with no effect in guanylyl cyclase B (GCB) receptor-expressing HEK cells (3.57 pmol/mL ± 0.53 vs 5.12 pmol/mL ±1.86 relative activity 1.4). Demonstrating its effect via the GLP-1 signaling pathway, it also increased cAMP levels at all doses in a 20 mM glucose medium (16.7 pmol/mL ± 1.47 vs 24.87 pmol/mL ± 2.53 p=0.0041, 22.95 pmol/mL ± 3.95 p=0.0042, and 23.19 pmol/mL ± 1.51 p=0.0036) in INS-1 cells, and doubled insulin secretion independent of the glucose environment (3.8 ng/mL ± 0.74 vs 7.1 ng/mL in 2.8 mM glucose p = 0.0019 and 4.4 ng/mL ± 0.44 vs 9.5 ng/mL ± 0.34 in 20 mM glucose p < 0.0001). In HCF cells, CRRL 101 attenuated alpha smooth muscle actin (α-SMA) activation by both insulin and transforming growth factor beta 1 (TGF-β1). In AC16 cells, CRRL 101 exhibited dose-dependent inhibition of insulin mediated apoptosis and a similar inhibition of TGF-β1 and insulin-mediated collagen secretion (85.11 µg/mL ± 15.32 vs 55.93 µg/mL ± 13.15 p=0.09; and 86.27 µg/mL ± 14.10 vs 48.20µg/mL ± 12.03 p=0.0331, respectively). Finally, CRRL 101 demonstrated marked adipose browning in HPA-vis (Figure 1).
Conclusion
CRRL 101 is a GCA-selective and GLP-1 chimeric bispecific biologic with favorable insulinergic, anti-apoptotic, anti-fibrotic, and pro-adipose browning effects uniquely mediated through its activity at the GLP-1 and GCA receptors. Further in vivo studies are in progress to explore its therapeutic potential.
心脏代谢疾病通过胰岛素抵抗、细胞凋亡和心肌纤维化导致心力衰竭,并保留射血分数。我们的新双特异性生物(CRRL 101)通过靶向GLP-1和GCA途径来减轻这些过程。方法采用转染的人胚胎肾(HEK)细胞、INS-1大鼠胰腺β细胞、人心脏成纤维细胞(HCF)、AC16人心肌细胞和人内脏前脂肪细胞(HPA-vis)对CRRL 101(10µM)进行体外评价。数据采用GraphPad Prism 9.4.1进行分析,以均数±SEM表示。结果CRRL 101显著提高了表达gca的HEK细胞中环鸟苷单磷酸(cGMP)水平(8.9 pmol/mL±5.1 vs 457.2 pmol/mL±64.9相对活性100),而对表达GCB受体的HEK细胞无影响(3.57 pmol/mL±0.53 vs 5.12 pmol/mL±1.86相对活性1.4)。证明其效果通过GLP-1信号通路,它也增加了营水平在所有剂量20毫米葡萄糖培养基(16.7 pmol /毫升±1.47 vs 24.87 pmol /毫升p = 0.0041±2.53,3.95±22.95 pmol /毫升p = 0.0042,和23.19 pmol /毫升±1.51 p = 0.0036)在INS-1细胞胰岛素分泌,独立于葡萄糖环境(3.8 ng / mL±0.74 vs 7.1 ng / mL 2.8毫米葡萄糖p = 0.0019和4.4 ng / mL±0.44 vs 9.5 ng / mL 0.34±20毫米葡萄糖p & lt; 0.0001)。在HCF细胞中,CRRL 101可减弱胰岛素和转化生长因子β1 (TGF-β1)对α-平滑肌肌动蛋白(α-SMA)的激活。在AC16细胞中,CRRL 101对胰岛素介导的凋亡表现出剂量依赖性的抑制作用,对TGF-β1和胰岛素介导的胶原分泌也表现出类似的抑制作用(分别为85.11µg/mL±15.32 vs 55.93µg/mL±13.15 p=0.09; 86.27µg/mL±14.10 vs 48.20µg/mL±12.03 p=0.0331)。最后,CRRL 101在HPA-vis中显示出明显的脂肪褐变(图1)。结论crrl 101是一种GCA选择性和GLP-1嵌合的双特异性生物制剂,具有良好的胰岛素能、抗凋亡、抗纤维化和促脂肪褐变作用,其作用是通过其对GLP-1和GCA受体的活性来介导的。进一步的体内研究正在进行中,以探索其治疗潜力。
