Valvular Heart Failure Is A Distinct Heart Transplant Phenotype With Comparable Adjusted Survival To Other Heart Failure Etiologies, Devon Kelley, Varun Kathawate, Joyce Ho, Andrew Belec, Takahiro Tashima, Kazuhiro Ueno, Jessica Dominic, Pavan Atluri

Division of Cardiology Faculty Papers

PURPOSE: Valvular heart failure (VHF) accounts for 1-5% of heart transplant listings. Comparative outcomes relative to other heart failure etiologies remain poorly characterized. This study defines the VHF phenotype and compares waitlist and transplant outcomes to other heart failure recipients.

METHODS: This retrospective cohort study uses the UNOS thoracic transplant database to analyze adult, first-time, heart-only listings with a diagnosis of heart disease. Patients were grouped by diagnosis as VHF or non-VHF. The primary outcome was waitlist events; post-transplant survival and outcomes were secondary analyses. Subgroup analysis was performed in the post-2018 allocation era.

RESULTS: VHF recipients were older (55.3 …

METHODS: Outcomes after redo-TAVR with Evolut R, Evolut PRO, and Evolut PRO+ valves in the Society of Thoracic Surgeons/American College of Cardiology TVT (Transcatheter Valve Therapy) Registry were analyzed and compared with outcomes after native-valve TAVR using the same valve platform during the …

A Case Report Of Myocardial Infarction Complicated With Blood Pressure Fluctuations Caused By Pheochromocytoma, Huiping Li, Wei Yang, Yu Feng, You Zhang, Gan-Xin Yan, Chuanyu Gao

Department of Medicine Faculty Papers

Pheochromocytoma typically presents with sustained or paroxysmal hypertension, but initial manifestation as acute non-ST-segment elevation myocardial infarction (NSTEMI) is rare. Peri-procedural hemodynamic fluctuations are often dramatic, making diagnosis and management challenging. We report a 51-year-old male admitted with chest tightness for 17 days. Elevated troponin and coronary angiography showing multivessel disease with total occlusion of the mid-left anterior descending artery (LAD) led to a preliminary diagnosis of NSTEMI. During percutaneous coronary intervention, blood pressure surged to 240/130 mmHg; intravenous nitroprusside caused an instantaneous drop to 95/55 mmHg, with rapid rebound to >200 mmHg upon withdrawal, showing no clear temporal relationship …

Division of Cardiology Faculty Papers

Risk factors (RF) for permanent pacemaker (PPM) placement in cardiac surgery include valvular operations and redo operations. We aim to identify RF for PPM placement prior to discharge (DC) specifically among redo mitral valvular operations, and to analyze outcomes in this population. Our retrospective review considered 943 patients undergoing redo MV operations between 01/2002 and 12/2021, excluding patients experiencing in-hospital death within 48 hours of their operation and patients with existing PPM or implanted cardiac defibrillator (ICD). Patients (n = 742) were categorized based on whether they received a PPM before DC or not. Of the 742 patients analyzed, 47 …

In Vivo Evidence Of Blood Flow Slippage: Failure Of The No-Slip Boundary Condition Assumption, Alena Jarolímová, Jaroslav Hron, Karel Tůma, Radomír Chabiniok, Josef Málek, Keshava Rajagopal

Division of Cardiology Faculty Papers

The assumption that blood adheres to vessel walls with zero tangential velocity component, the so-called "no-slip" boundary condition, is a foundational premise of cardiovascular fluid dynamics. Whether the no-slip condition holds in vivo, however, remains unknown. Seven healthy adult volunteers underwent cardiovascular magnetic resonance imaging. With four-dimensional flow magnetic resonance imaging of the descending thoracic aorta and modeling blood as a Navier-Stokes fluid, near-wall blood velocities were quantified, and wall shear stress was calculated based on the measured velocity fields. Within the Navier-Stokes data assimilation framework, tangential wall velocities of ∼30-80% of the mean luminal velocity were consistently obtained. These …

OhioHealth Research Institute Articles

BACKGROUND: Arrhythmia burden in ambulatory patients with symptomatic heart failure (HF) without cardiac implantable electronic devices (CIEDs) is not well defined, and it remains uncertain whether device-guided remote congestion management modifies arrhythmia occurrence.

OBJECTIVES: The goal was to assess whether arrhythmia burden differed between randomized congestion-management strategies and characterize the occurrences and associations of insertable cardiac monitor (ICM)-detected arrhythmias with therapeutic actions and clinical events.

METHODS: In ALLEVIATE-HF, patients with NYHA functional class II-III HF with any ejection fraction (EF) and a recent HF event, without prior CIEDs, underwent ICM implantation and were randomized to ICM-guided, physician-directed, nurse-facilitated congestion management …

Electronic Health Record Alerts To Improve Lipid Lowering After A Recent Myocardial Infarction, Dean G. Karalis, Benjamin Richter, Scott Hessen, Patrick Moeller, Laney K. Jones

Division of Cardiology Faculty Papers

BACKGROUND: This observational, quality initiative evaluated the impact of changing from a passive (dismissible) to an active (nondismissible without action) electronic health record alert on guideline-recommended lipid-lowering therapy (LLT) prescriptions in patients with recent myocardial infarction at risk for secondary events.

METHODS: We sequentially recruited a retrospective passive-alert (February 2018-July 2019; n=733) and a prospective active-alert (August 2020-January 2022; n=587) cohort of patients who triggered an alert to intensify LLT or order a low-density lipoprotein-cholesterol (LDL-C) test if they had a recent myocardial infarction (within 12 months) and elevated (≥70 mg/dL) or missing LDL-C. Prescribed LLTs and cumulative percentages of …

Apolipoprotein B100 Predicts Cardiovascular And Limb Events In Type 2 Diabetes Patients With Chronic Limb-Threatening Ischemia, Federico Biscetti, Maria Margherita Rando, Maria Anna Nicolazzi, Flavia Angelini, Roberto Iezzi, Luis H. Eraso, Paul J. Dimuzio, Dario Pitocco, Massimo Massetti, Antonio Gasbarrini, Andrea Flex

Department of Surgery Faculty Papers

BACKGROUND: Patients with type 2 diabetes mellitus (T2DM) and chronic limb-threatening ischemia (CLTI) undergoing lower extremity revascularization (LER) face high risks of major adverse cardiovascular events (MACE) and major adverse limb events (MALE), despite guideline-directed lipid-lowering therapy. Apolipoprotein B100 (ApoB100), reflecting total atherogenic particle number, may identify residual risk beyond LDL-cholesterol (LDL-C). Therefore, we investigated whether baseline ApoB100 levels independently predict MACE and MALE beyond conventional risk factors in this high-risk population.

METHODS: In this prospective cohort study, 167 T2DM patients with CLTI undergoing LER were followed for 12 months with visits at 1, 3, 6, and 12 months post-procedure. …

Sex-Based Disparities In Health Care Access And Utilization Among Patients With Atrial Fibrillation, Ji Mei May Wong, Peter R. Kowey

Department of Medicine Faculty Papers

IMPORTANCE: Females with atrial fibrillation (AF) experience a higher risk of stroke, myocardial infarction, and mortality than males with AF. Theories suggest that sex-based differences in hormonal, structural, and electrophysiologic factors are associated with this imbalance; we hypothesized that sex-based differences in health care access and utilization (HCAU) are also underlying factors.

OBJECTIVE: To determine whether sex-based disparities in HCAU barriers exist among individuals with AF.

DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study used data on patients with AF in the All of Us Research Program Registered Tier dataset (version 8), which contains integrated data from the electronic health record …

Pediatric cardiothoracic surgeries are high-stakes, complex procedures, typically undergoing prior review at multidisciplinary conferences. This study evaluates practice patterns of conferences throughout the United States (US). Surveys were distributed to fellowship program directors or division directors in 124 US pediatric cardiology centers seeking information on conference logistics, fellow roles, quality improvement (QI), and satisfaction. All 47 responding centers (response rate 38%) conduct presurgical conferences, mostly on a weekly basis (92%) lasting 60-120 min (79%). The conferences are solely virtual (19%) or hybrid (81%). High-volume centers (> 300 surgical cases/year) are more likely to hold multiple conferences (13/20 vs 7/27, p <  0.01) and less likely to designate a moderator (11/20 vs 22/26, p = 0.027). Categorical pediatric cardiology fellows at 33 centers present clinical data (97%), echocardiograms (85%), catheterizations (82%), and cross-sectional imaging (39%), typically beginning in their first year. Most centers report that minor (98%) or major changes (51%) are made to patient management at least "sometimes." Responders rate conferences as very important (median 10/10 on a 10-point Likert scale, IQR 9-10), but satisfaction is more modest (median 7/10, IQR 7-9). Only 17% of centers have a formal QI process. Comments from 42 centers reveal positive themes of collaboration (68%) but also concerns about lengthy (30%) or inefficient (36%) discussion. Conclusions: This survey highlights common practices for pediatric cardiothoracic presurgical conferences. Conferences are collaborative and seen as highly impactful. However, satisfaction varies, and QI efforts are infrequent. These findings highlight opportunities for process improvement and standardization.

IMPORTANCE: Female patients with heart failure (HF) are older and more often present with preserved left ventricular ejection fraction (LVEF), whereas male patients present with more ischemic disease. Despite these differences, an emergency department-based acute HF strategy may be equally applicable to both sexes.

OBJECTIVE: To determine whether the strategy for acute HF management in the Comparison of Outcomes and Access to Care for Heart Failure (COACH) trial differed by sex.

DESIGN, SETTING, AND PARTICIPANTS: This prespecified secondary analysis of the multicenter COACH stepped-wedge, cluster-randomized clinical trial included 10 acute care hospitals in Ontario, Canada. Data were collected from January …

Out-Of-Pocket Costs And Antihypertensive Medication Use Among Veterans: A Natural Experiment, Alexander R. Zheutlin, Alexander Chaitoff, Daniel Addo, Joshua A. Jacobs, Catherine G. Derington, Eric L. Stulberg, Peter A. Glynn, Bernardo Modenesi, Jordana B. Cohen, Adam P. Bress

Department of Neurology Faculty Papers

BACKGROUND: Blood pressure (BP) control remains suboptimal in the United States despite available low-cost antihypertensive medications. Even small out-of-pocket medication costs may contribute to adherence. We determined whether $0 versus >$0 out-of-pocket costs for antihypertensive medications is associated with differences in adherence, discontinuation, BP control, and cardiovascular outcomes.

METHODS: We included veterans with newly diagnosed hypertension who initiated antihypertensive medication in the Veterans Health Administration from 2004 to 2022. A fuzzy regression discontinuity design with 2-stage residual inclusion leveraged differences in medication copay policy at a 50% service-connected disability threshold (≥50% service-connected disability: $0 out-of-pocket cost versus < 50%: $8 monthly cost). Outcomes included 1-year medication nonadherence (proportion of days covered < 80%), 1-year medication discontinuation (no medication in the final 90 days of the study year), 1-year BP control (systolic BP/diastolic BP < 140/90 mm Hg and < 130/80 mm Hg) and cardiovascular disease events (myocardial infarction, coronary revascularization, peripheral artery disease, or stroke).

RESULTS: Among 417 …

Department of Medicine Faculty Papers

OBJECTIVES: There is debate regarding the optimal choice for a second conduit in coronary artery bypass grafting. The right internal mammary artery (RIMA) is commonly employed as a second conduit; however, it is unclear whether the free (fRIMA) or in situ (isRIMA) configuration yields superior outcomes. We performed a systematic review and meta-analysis to compare clinical outcomes between fRIMA and isRIMA as the second conduit.

METHODS: A comprehensive search of PubMed (MEDLINE), EMBASE, and CENTRAL was performed through May 2025 to identify studies comparing outcomes in patients undergoing coronary artery bypass grafting with either fRIMA or isRIMA as a second …

Student Papers, Posters & Projects

BACKGROUND: Coronary microvascular dysfunction (CMD) contributes to myocardial ischemia in patients both without obstructive coronary artery disease (e.g., MINOCA/INOCA) and in those with co-existing epicardial stenosis. While its etiology includes structural and functional causes. hematologic parameters have been linked to cardiovascular outcomes. However, the relationship between red blood cell (RBC) markers and microvascular resistance remains poorly characterized. We aim to evaluate whether RBC parameters are correlated with the angiography-derived index of microcirculatory resistance (angio-IMR).

METHODS: This retrospective study evaluated the association between red blood cell (RBC) parameters and angio-IMR in patients with intermediate coronary artery disease (30%-70% stenosis). Data were …

Department of Medicine Faculty Papers

INTRODUCTION: Relationship between changes in cardiac function, functional capacity, and patient-reported health status in heart failure (HF) remains incompletely defined, which may help inform endpoint selection and clarify how distinct clinical domains reflect treatment response.

METHODS: This post hoc analysis of the randomized cardiac microcurrent (C-MIC) II trial, which evaluated the efficacy and safety of C-MIC therapy in patients with chronic HF with reduced ejection fraction on optimal guideline-directed medical therapy, included 65 ambulatory patients with non-ischaemic dilated cardiomyopathy, New York Heart Association (NYHA) Class III-IV symptoms, and baseline left ventricular ejection fraction (LVEF) 25-35%. Correlations between changes in Kansas …

Two Faces Of Mitral Stenosis: Uncovering Structural And Hemodynamic Signatures Of Rheumatic And Mitral Annular Calcification-Induced Disease, Mohammad S. Hashemi, Peter Abdelmaseeh, Atif Nehvi, Gregg S. Pressman, Arash Kheradvar

Einstein Health Papers

BACKGROUND: Mitral annular calcification (MAC) is common and associated with increased cardiovascular risk and, when severe, mitral stenosis (MS). MAC-related MS differs anatomically and hemodynamically from rheumatic MS (RMS), challenging standard diagnostic methods. This study compares structural and flow characteristics, including  kinetic energy losses, across MAC-related MS, RMS, and normal mitral valves, and evaluates the applicability of conventional diagnostic metrics in MAC.

METHODS: Three-dimensional transesophageal echocardiographic data sets from 70 patients (22 normal mitral valves, 26 RMS valves, 22 MAC valves) were used to obtain linear, area, and volumetric measurements for valve comparison. Representative valves from each group were converted …

The Treatment Of Obesity In The Context Of The Obesity Paradox In Patients With Heart Failure: A Narrative Review, Pamela L. Alebna, Sarah Martey, Anurag Mehta, Carl J. Lavie, Salvatore Carbone

EVMS School of Health Professions Faculty Publications

Purpose of review

While excess adiposity is a known risk factor for incident heart failure ( HF), once the condition is established, observational data suggest that increased body mass index (BMI) may confer a survival advantage. This paradox has emphasized the underlying roles of cardiorespiratory fitness (CRF), and body composition, particularly lean mass (LM), in influencing clinical outcomes.

Recent findings

In this review, we explore the multifaceted nature of the obesity paradox in HF, with a focus on emerging anti-obesity incretin-mimetic therapies, such as glucagon-like peptide-1 receptor agonists (GLP-1 RAs) and dual GLP-1/glucose-dependent insulinotropic polypeptide (GIP) receptor agonists. These agents …

Department of Biomedical and Translational Sciences Faculty Publications

Background

Heart failure with preserved ejection fraction (HFpEF) arises from chronic cardiometabolic and vascular stress and is increasingly recognized as an inflammatory syndrome with immune dysregulation. Regulatory T cells (Tregs) are critical modulators of cardiovascular inflammation, yet the mechanisms driving Treg dysfunction in HFpEF remain poorly defined. stromal interaction molecule 1 (STIM1)-dependent calcium signaling is a key stress-responsive pathway in immune cells; however, its role in Treg maladaptation during HFpEF remains unknown.

Methods

Circulating Tregs from patients with and without HFpEF were analyzed for abundance, STIM1 expression, and stress-associated signaling pathways. To establish causality, mice with Treg-specific deletion of STIM1 …

Time-to-first-event analyses were stratified by inpatients and outpatients …

Comparative Value Of Echocardiography Vs. Right Heart Catheterization In Heart Failure With Preserved Ejection Fraction, Nathanael Tran, Mohammad Shaar, Hussein Al-Sudani, Ramy Sedhom, Hamza Akhtar, Kevin Bryan Lo, Gregg S. Pressman

Einstein Health Papers

BACKGROUND: Echocardiography and right heart catheterization (RHC) are useful in the evaluation of heart failure with preserved ejection fraction (HFpEF). We compared the two among decompensated HFpEF patients to determine their relative value in predicting all-cause mortality and a composite of cardiovascular (CV) death and heart failure (HF) readmission at 1 year.

METHODS: One hundred seventy-eight decompensated HFpEF patients who underwent both procedures and survived to hospital discharge were retrospectively identified. Hospital records and the National Death Index were queried to determine outcomes. Echocardiographic and invasive parameters were tested for significant associations with each outcome. Additionally, three predictive models were …

Left And Right Ventricular Strain Mechanics In Fetal Tachyarrhythmia., Rukmini Komarlu, Janelle R. Noel-Macdonnell Phd, Neha Chellu, Geetha Haligheri

Manuscripts, Articles, Book Chapters and Other Papers

Introduction: Assessment of myocardial function in fetuses with supraventricular tachyarrhythmia is challenging. Speckle-tracking echocardiography (STE) is a newer sensitive method to assess ventricular systolic function. We sought to assess left (LV) and right (RV) ventricular myocardial strain mechanics in fetuses with tachyarrhythmia and hypothesized that strain mechanics are impaired in this patient population even after conversion to sinus rhythm.

METHODS: This was a single-center retrospective review. LV and RV strain parameters were assessed using STE in tachyarrhythmia and after conversion to sinus rhythm and, compared to gestational age (GA), matched control fetuses in sinus rhythm.

RESULTS: Eighteen fetuses with tachyarrhythmia …
