Circulation, Volume 150, Issue Suppl_1, Page A4144512-A4144512, November 12, 2024. Introduction:Transcatheter edge-to-edge repair of the mitral valve with the MitraClip has offered a less invasive percutaneous alternative to surgical repair in select candidates with mitral regurgitation. Various factors impact the outcomes of MitraClip. We investigated the impact of nutritional status on the outcomes of MitraClip.Methods:Utilizing the nationwide inpatient sample data for years from January 1, 2016, and December 31, 2021, patients who underwent MitraClip were identified. They were categorized based on obesity and protein energy malnutrition (PEM). Statistical significance was assigned at p

Circulation, Volume 150, Issue Suppl_1, Page A4139144-A4139144, November 12, 2024. Background:Iron deficiency anemia (IDA) affects approximately one-third of patients with systolic heart failure, yet comprehensive population-based analyses of its impact on in-hospital outcomes remain limited. This study seeks to examine how IDA influences in-hospital outcomes among individuals with decompensated systolic congestive heart failure (HFrEF).Methods:Using data from the National Inpatient Sample (NIS) database spanning from 2017 to 2021, this study identified patients hospitalized for decompensated systolic congestive heart failure (HFrEF) with a secondary diagnosis of IDA using ICD-10 codes such as I5020-23 and D500, D501, D508, D509. Propensity score matching (PSM) was then employed to create cohorts without and with IDA at a 1:3 ratio. Multivariate regression analyses were conducted to evaluate various outcomes, including in-hospital mortality, cardiogenic shock (CS), acute myocardial injury (AMI), cardiac arrest, ventricular tachycardia (VT), ventricular fibrillation (VF), length of stay (LOS), and total hospitalization charges. Furthermore, the utilization rate of mechanical ventilation and circulatory support, including intra-aortic balloon pump and extracorporeal membrane oxygenation, was evaluated in both cohorts.Results:Among 253,034 HFrEF hospitalizations, 16,200 (6.4%) had a secondary diagnosis of IDA. After PSM, multivariate regression analyses revealed no significant differences in the odds of cardiogenic shock (10% vs. 10%, p=0.86), in-hospital mortality (2.6% vs. 2.8%, p=0.71), and LOS (7.19 vs. 7.27 days) between the two groups. Additionally, the likelihood of cardiac arrest, ventricular arrhythmias, AMI, and utilization of mechanical ventilation and circulatory support did not reach statistical significance. However, patients with IDA and HFrEF had higher hospitalization charges ($85,516 vs. $93,000).Conclusion:HFrEF patients, with or without IDA, had similar odds of cardiogenic shock, in-hospital mortality, mechanical circulatory support utilization, as well as LOS. However, IDA with HFrEF correlated with higher hospitalization charges.

Circulation, Volume 150, Issue Suppl_1, Page A4144552-A4144552, November 12, 2024. Background:Heart Failure(HF) significantly deteriorates outcomes in patients with Atrial Fibrillation. Heart Failure with Preserved Ejection Fraction(HFpEF) and Atrial Fibrillation(AFib) share common disease progression pathways and are gradually increasing in prevalence.Aim:We aim to study the variation in characteristics and outcomes based on type of heart failure in patients with AFib using the National Readmission Database(2016-2020).Methods:NRD database was used to identify patients with Atrial Fibrillation using ICD-10 codes. Patients were stratified into two groups based on the presence of systolic dysfunction and diastolic dysfunction. Patients with combined systolic and diastolic dysfunction were excluded. Information was collected on patient demographics, comorbidities, and outcomes. Propensity score matching was performed to compare outcomes among AFib patients with HFrEF and HFpEF.Results:A total of 6,673,080 patients with AFib and isolated systolic or isolated diastolic dysfunction were included in the analysis. 3,914,695(58.66%) had HFpEF and 2,758,385 (41.34%%) had HFrEF. In the HFpEF group 57.8% were females in comparison with 33.12% females in the HFrEF group. HFpEF group had a higher rate of hypertension (84.9% vs 82%, p

Circulation, Volume 150, Issue Suppl_1, Page A4131460-A4131460, November 12, 2024. Background:Chronic kidney disease (CKD) is associated with risk of myocardial infarction (MI) and anemia. Among patients with CKD and anemia who experience MI, it remains uncertain if a liberal transfusion threshold (LTT) strategy (hemoglobin cutoff [Hgb] < 10 g/dL) is superior to a restrictive transfusion threshold (RTT, Hgb 7-8 g/dL) strategy.Objectives:To evaluate outcomes of those with CKD randomized to RTT vs. LTT in the Myocardial Ischemia and Transfusion (MINT) trial (NCT02981407).Methods:Among 3,495 MINT participants with non-missing creatinine (99.7%), we compared the baseline characteristics and outcomes at 30 days post-randomization of those individuals without CKD (N = 1279), CKD with eGFR 30-60 mL/min/1.73 m2(N = 999), CKD with eGFR < 30 mL/min/1.73 m2(N = 802), and CKD requiring dialysis (N = 415), both overall and by randomized transfusion strategy. Interaction terms for eGFR category by treatment assignment on each outcome were assessed.Results:Individuals with CKD compared to those without CKD more frequently presented with NSTEMI (all p < 0.001) and had a greater risk of all-cause death, recurrent MI, rehospitalization, and heart failure (all p < 0.05). Compared to a liberal transfusion strategy, a restrictive strategy among non-dialysis dependent individuals with an eGFR < 30 mL/min/1.73 m2was associated with an increased risk of death/recurrent MI (Figure 1) and unplanned rehospitalization (Figure 2). Among individuals with an eGFR 30-60 mL/min/1.73 m2, a restrictive strategy was associated with an increased risk of cardiac death (Figure 1). No eGFR category by treatment assignment interaction terms were significant.Conclusions:In this prespecified analysis, individuals with CKD were at greater risk of death, recurrent MI, heart failure, and unplanned rehospitalization at 30 days post-randomization than those without CKD. In individuals with CKD, a restrictive transfusion strategy was associated with increased risk of adverse outcomes.

Circulation, Volume 150, Issue Suppl_1, Page A4141644-A4141644, November 12, 2024. Background:Previous studies have shown conflicting results regarding higher rates of contrast-induced acute kidney injury (CI-AKI) after percutaneous coronary intervention (PCI) among women as compared to men. We sought to identify covariates that explain possible sex differences in rates of CI-AKI after PCI.Methods:This was a retrospective observational cross-sectional study of all PCIs performed at Cedars-Sinai Medical Center from 2020-2023, sourced from the National Cardiovascular Data Registry. The primary outcome and regressor were CI-AKI and sex, respectively. Covariates were other patient demographics, comorbidities, procedural factors, and health insurance. We excluded patients with pre-PCI dialysis requirement or without pre/post-PCI creatinine. We used multivariable-adjusted logistic regression to evaluate rates of CI-AKI among women versus men. Using additive adjustment, we identified factors that accounted for the sex differences.Results:Of 2971 PCIs included, 820 (27.6%) were performed in women, 316 (10.6%) in Black patients and 283 (9.5%) in Hispanic patients. On average, women were older than men (73.9 vs 68.6 years, p

Circulation, Volume 150, Issue Suppl_1, Page A4139444-A4139444, November 12, 2024. Case Presentation:A 39-year-old Southeast Asian female presented with fatigue and exertional dyspnea. She underwent a myomectomy four years ago. Examination showed vital signs within normal limits, except for an SpO2 of 87%. Blood tests indicated microcytic hypochromic anemia and elevated D-Dimer levels of 1479 ng/mL.A transthoracic echocardiogram revealed a large mass occupying almost the entire right atrium, extending into the inferior vena cava. A CT scan showed a large, low attenuation, and minimally enhanced mass extending from the right atrium into the inferior vena cava and right hepatic vein, possibly invading segments VII-VIII of the liver (Figure 1). Abdominal CT and MR images revealed multiple degenerating uterine fibroids, bilateral dilated uterine tubes, and mild right hydronephrosis (Figure 2).The patient underwent surgical removal of the cardiac mass under general anesthesia with extracorporeal circulation and hypothermia. Pathological examination confirmed a benign tumor characterized by bundles of smooth muscle cells (Figure 3). Immunohistochemical staining with Actin (+), Progesterone receptor (+), Desmin (+), Ki67 (+) was consistent with a diagnosis of benign metastasizing leiomyoma (BML) of the heart. Subsequently, elective hysterectomy and bilateral salpingo-oophorectomy were performed.Discussion:Although rare, uterine leiomyoma can exhibit metastatic behavior, disseminating to extraneous anatomical sites. BML should be considered in the differential diagnosis when patients present with an atypical cardiac mass and have a history of uterine leiomyoma, myomectomy, or hysterectomy.BML of the heart is an exceptionally rare condition, predominantly affecting middle-aged women who have undergone hysterectomy or myomectomy. While BML commonly occurs in pre-menopausal patients and shares a potentially similar mechanism with endometriosis, as indicated by its response to estrogen-blocking agents, the occurrence of BML in post-menopausal women suggests the involvement of other contributing factors.Multiple imaging modalities play a significant role in the diagnosis and preparation for surgical management.

Circulation, Volume 150, Issue Suppl_1, Page A4144763-A4144763, November 12, 2024. Background:Anemia is frequently observed as a comorbidity in atrial fibrillation (AF) and is associated with poor clinical outcomes.Purpose:We aim to investigate the impact of anemia on clinical outcomes in AF Patients on oral anticoagulants.Methods:We comprehensively searched PubMed, WOS, SCOPUS, EMBASE, and CENTRAL through March 2024 and conducted a prognostic systematic review and meta-analysis. All analyses were performed using R V. 4.3.1.Results:With the inclusion of 23 studies, our cohort comprised a total of 286,781 patients. Anemia was significantly associated with an 86% increase in the risk of major bleeding (HR: 1.86 with 95% CI [1.61, 2.14], P< 0.01), a 25% increase in the risk of intracranial hemorrhage (HR: 1.25 with 95% CI [1.02, 1.54], P= 0.03), a 92% increase in the risk of gastrointestinal bleeding (HR: 1.92 with 95% CI [1.68, 2.19], P< 0.01), and a 91% increase in the risk of all-cause mortality (HR: 1.91 with 95% CI [1.46, 2.51], P< 0.01). However, Anemia did not significantly affect the risk of stroke, TIA, or systemic embolism (HR: 1.07 with 95% CI [0.93, 1.22], P= 0.36).Conclusion:Anemia was significantly associated with an increased risk of major bleeding, intracerebral hemorrhage, gastrointestinal bleeding, and all-cause mortality without impacting stroke, TIA, or systemic embolism. Further research is warranted to compare the effects of DOACs and vitamin K antagonists. Clinically, it is imperative to closely monitor the anemic status of patients due to these elevated risks.

Circulation, Volume 150, Issue Suppl_1, Page A4128352-A4128352, November 12, 2024. Background:G6PD deficiency classically presents with hemolytic anemia, but associations have been described with atherogenesis and coronary artery disease. There are limited data that also suggest a link between G6PD deficiency and the development of congenital heart disease (CHD).Hypothesis:We hypothesize a higher incidence of CHD among individuals with G6PD deficiency as well as worse hospital outcomes for those with CHD and G6PD deficiency.Methods:We reviewed the Vizient® Clinical Data Base (a national, administrative database) from 10/2019-3/2024 for admissions of individuals aged 0-25 years with ICD-10 codes for moderate to severe CHD with and without and G6PD deficiency (D55.0, D75.A) to calculate and compare CHD incidence. Additional data included: demographics, hospital outcomes and costs. Hospital outcomes were compared using t-tests for normally distributed data, Mann-Whitney U test for non-normally distributed data and χ2for categorical data.Results:There were 213,708 admissions of individuals with CHD and

Circulation, Volume 150, Issue Suppl_1, Page A4145777-A4145777, November 12, 2024. Background:The literature regarding outcomes among patients with coagulopathy who had left atrial appendage occlusion (LAAO) device procedure is limited. This study evaluated the inpatient outcomes among patients that underwent LAAO with and without diagnosed coagulable disorders.Methods:Patients that underwent LAAO were collected from the National Inpatient Sample database 2016-2019. Patients were stratified by the presence of diagnosed coagulable disorders. Demographic and comorbidity data were collected. Bleeding events and inpatient mortality were assessed. Chi-square and binary logistic regression analyses were utilized. Factors with p

Circulation, Volume 150, Issue Suppl_1, Page A4124313-A4124313, November 12, 2024. A 30-year-old male electrician presented with two days of fever and positional left shoulder pain and was found to have elevated inflammatory markers and a large pericardial effusion with echocardiographic evidence of tamponade for which he underwent pericardiocentesis. He was discharged on a course of anti-inflammatory therapy with presumed diagnosis of idiopathic pericarditis based on negative cytology. He returned 6 months later with several weeks of upper respiratory infection symptoms as well as new abdominal discomfort and emesis.On presentation, his vital signs were notable for tachycardia to 113 and cardiac exam was notable for tachycardia, regular rhythm, no rubs or murmurs, nondisplaced precordial impulse, normal jugular venous pressure with Kussmaul sign, and pulsus paradoxus of 6. An electrocardiogram showed sinus tachycardia with diffuse ST segment changes (Figure A). His cardiac biomarkers were unremarkable (troponin 21). His labs revealed normocytic anemia with hemoglobin of 11 and erythrocyte sediment rate above assay. Echocardiogram demonstrated a circumferential complex pericardial effusion with echocardiographic evidence of early tamponade (Figure B, C). A pericardiocentesis was attempted with inability to advance wire within pericardial space. A malignancy workup was initiated. CT demonstrated multi-station thoracic and lower cervical lymphadenopathy, moderate left pleural effusion, and an intrapericardial mass with associated pericardial effusion (Figure D). Cardiac magnetic resonance imaging demonstrated a circumferential intrapericardial non-mobile mass measuring up to 22 mm in thickness posteriorly and the mass was isointense to myocardium indicating low-fat content (Figure E). A supraclavicular lymph node biopsy was obtained with immunohistochemical staining positive for WT1 and calretinin, consistent with metastatic epithelioid mesothelioma of pericardial versus pleural etiology (Figure F). A PET-CT subsequently showed a FDG-avid circumferential anterior pericardial mass and multiple pleural-based lesions concerning for metastatic mesothelioma. He was initiated on pemetrexed/carboplatin systemic chemotherapy. With systemic therapy, his disease has been stable for 6 months. Pericardial mesothelioma is a rare malignancy. This case underscores the diagnostic challenges associated with pericardial mesothelioma and the importance of cancer workup as part of the pericardial effusion workup.
