Sharp, Huijing Xia, Karl Moles, Kashyap Koul, John S. Wang, David J. Polhemus, Traci T. Goodchild, Ravi B. Patel, Sanjiv J. Shah, David J. Lefer

School of Medicine Faculty Publications

BACKGROUND: Recent studies have suggested that cardiac nitrosative stress mediated by pathological overproduction of nitric oxide (NO) via inducible NO synthase (iNOS) contributes to the pathogenesis of heart failure with preserved ejection fraction (HFpEF). Other studies have suggested that endothelial NO synthase (eNOS) dysfunction and attenuated NO bioavailability contribute to HFpEF morbidity and mortality. We sought to further investigate dysregulated NO signaling and to examine the effects of a NO-based dual therapy (sodium nitrite+hydralazine) following the onset of HFpEF using a “2-hit” murine model. METHODS AND RESULTS: Nine-week-old male C57BL/6 N mice (n=15 per group) were treated concurrently with high-fat …

Cytosolic Dna Sensing Protein Pathway Is Activated In Human Hearts With Dilated Cardiomyopathy, Leila Rouhi, Sirisha M Cheedipudi, Benjamin Cathcart, Priyatansh Gurha, Ali J Marian

Faculty, Staff and Student Publications

INTRODUCTION: The genome is constantly exposed to numerous stressors, which induce DNA lesions, including double-stranded DNA breaks (DSBs). DSBs are the most dangerous, as they induce genomic instability. In response to DNA damage, the cell activates nuclear DNA damage response (DDR) and the cytosolic DNA sensing protein (CDSP) pathways, the latter upon release of the DSBs to the cytosol. The CDSP pathway activates NFκB and IRF3, which induce the expression of the pro-inflammatory genes. There is scant data on the activation of the CDSP pathway in human hearts with dilated cardiomyopathy (DCM).

AIM: We aimed to determine expression levels of …

Neprilysin Inhibitors In Heart Failure: The Science, Mechanism Of Action, Clinical Studies, And Unanswered Questions, Biykem Bozkurt, Ajith P Nair, Arunima Misra, Claire Z Scott, Jamal H Mahar, Savitri Fedson

Faculty, Staff and Students Publications

This article provides a contemporary review and a new perspective on the role of neprilysin inhibition in heart failure (HF) in the context of recent clinical trials and addresses potential mechanisms and unanswered questions in certain HF patient populations. Neprilysin is an endopeptidase that cleaves a variety of peptides such as natriuretic peptides, bradykinin, adrenomedullin, substance P, angiotensin I and II, and endothelin. It has a broad role in cardiovascular, renal, pulmonary, gastrointestinal, endocrine, and neurologic functions. The combined angiotensin receptor and neprilysin inhibitor (ARNi) has been developed with an intent to increase vasodilatory natriuretic peptides and prevent counterregulatory activation …

Glucocentric Drugs In Cardiovascular Disease Protection And Heart Failure, Khawaja M. Talha, Gregg C. Fonarow, Salim S. Virani, Javed Butler

Office of the Provost

Evidence for cardiovascular outcomes with older-generation antihyperglycemic drugs in the management of type 2 diabetes is based on aggregated data from prior randomized controlled trials and observational studies that were not focused on prespecified cardiovascular end points. Newer antihyperglycemic medications have undergone a rigorous evaluation of cardiovascular outcomes through randomized controlled trials since the US Food and Drug Administration imposed a mandatory requirement for all glucose-lowering drugs in 2008. The three classes of drugs that have been most extensively studied are dipeptidyl peptidase 4 inhibitors, glucagon-like peptide 1 receptor agonists, and sodium-glucose cotransporter-2 (SGLT2) inhibitors, the latter two reporting significant …

The Role Of Telehealth In Reducing Hospital Readmissions For Heart Failure Patients, Tommy Lee Bratcher

Graduate Theses, Dissertations, and Capstones

Heart failure affects over six million people annually, and is expected to increase to over eight million by 2030. Over 60 million people live in the rural United States. Telehealth is a tool to improve access to care, provide early intervention, and follow up with patients within 48 hours of a hospital discharge. Utilizing Telehealth to conduct a medication reconciliation within 48 hours of discharge to address any medication errors or admission, and reinforce adherence is a way to improve access to care to those living in rural areas.

Medication Complexity Among Older Adults With Hf: How Can We Assess Better?, Min Ji Kwak, Monica Cheng, Parag Goyal, Dae Hyun Kim, Scott L Hummel, Abhijeet Dhoble, Ashish Deshmukh, Rajender Aparasu, Holly M Holmes

Faculty, Staff and Student Publications

Medical management of heart failure (HF) has evolved and has achieved significant survival benefits, resulting in highly complex medication regimens. Complex medication regimens create challenges for older adults, including nonadherence and increased adverse drug events, especially associated with cognitive impairment, physical limitations, or lack of social support. However, the association between medication complexity and patients' health outcomes among older adults with HF is unclear. The purpose of this review is to address how the complexity of HF medications has been assessed in the literature and what clinical outcomes are associated with medication regimen complexity in HF. Further, we aimed to …

A Case Of Isolated Cardiac Burkitt Lymphoma Causing Right-Sided Heart Failure, Graham Rector, Stephanie J Koh, Rashed Tabbaa

The Texas Heart Institute Journal

Primary cardiac tumors are rare, as the most common cause of cardiac masses is from metastatic disease. In this article, a unique case of isolated cardiac Burkitt lymphoma causing right-sided heart failure in a 70-year-old man who presented to the emergency department with abdominal distension and lower-extremity swelling is described. The right ventricular mass was initially identified via computed tomographic scans of the abdomen and pelvis. Further workup included transthoracic echocardiogram and cardiac magnetic resonance imaging that showed extension of the mass into the right atrium and pericardium. Staging imaging and bone marrow biopsy revealed no evidence of metastatic disease. …

Aims: Heart failure (HF) is a common and morbid condition impacting multiple health domains. We previously reported the development of the PROMIS®-Plus-HF (PROMIS+HF) profile measure, including universal and HF-specific items. To facilitate use, we developed shorter, PROMIS+HF profiles intended for research and clinical use.

Methods and results: Candidate items were selected based on psychometric properties and symptom range coverage. HF clinicians (n = 43) rated item importance and clinical actionability. Based on these results, we developed the PROMIS+HF-27 and PROMIS+HF-10 profiles with summary scores (0-100) for overall, physical, mental, and social health. In a cross-sectional sample (n = 600), we …

Indicators Of Cardiac Autonomic Dysfunction Associated With Chronic Hyperglycemia: Implications On Vascular Surrogates And Heart Failure, Yap-Hang Chan, Bernard Man-Yung Cheung, Hung-Fat Tse

Journal of the Hong Kong College of Cardiology

Background: Limited data exist on the role of chronic hyperglycemia-related cardiac autonomic dysfunction in incident heart failure (HF). We investigated the relations of resting heart rate (HR) and PR interval with chronic hyperglycemia, and effects on new-onset HF.

Methods: We prospectively studied 550 patients with prior coronary disease, ischemic stroke and/ or type 2 diabetes. Incident HF was ascertained. Heart rate-PR interval dissociation was defined as counter-physiological co-occurrence of increased PR interval (>mean; 173.3ms) and increased resting HR (>mean; 64.4 beats/min).

Results: Over 63 ±11 months, 6.7% patients developed new-onset HF. Resting HR³75bpm was independently predictive of new-onset …

The Lawnmower And The Pediatric Lower Extremity: A Catastrophic Combination, Alvaro Tamayo-Gutierrez, Hassan N Ibrahim

Faculty, Staff and Student Publications

Heart failure can lead to renal impairment, an interaction now termed "cardiorenal syndrome." The prevalent physiological explanation for the renal impairment that accompanies heart failure centers around the forward failure hypothesis, which emphasizes the role of left ventricular dysfunction in causing edema, and the backward failure hypothesis, which singles out venous congestion as the dominant mechanism of edema and reduced glomerular filtration rate. In this review, we provide an appraisal on venous congestion, an extremely important contributor that has received little attention. We also summarize the pharmacology of loop diuretics, explain current understanding of diuretic resistance, and address controversies regarding …

The Texas Heart Institute Journal

Background

Since the introduction of cardiac resynchronization therapy (CRT) to improve left ventricular function, the effect of CRT on the right ventricle in patients with heart failure has not been well described.

Methods

We evaluated the effect of CRT on right ventricular systolic function in 20 patients (80% men; mean [SD] age, 58.5 [9.8] y) with cardiomyopathy and right ventricular systolic dysfunction (New York Heart Association class III or IV, left ventricular ejection fraction ≤35%, and QRS interval ≥120 ms). The median follow-up time was 15 months. Right ventricular systolic function, defined as a tricuspid annular plane systolic excursion (TAPSE) …

Understanding Intelligent Non-Adherence By Measuring The Differences In Knowledge, Attitudes, Beliefs, And Behaviors Of Self-Care In Heart Failure Patients, Marco Mimbela

Seton Hall University Dissertations and Theses (ETDs)

Background and Purpose of the Study: Research shows that six in ten U.S. adults have a chronic disease and four in ten have two or more (CDC, 2018). Of all chronic diseases, heart failure is the leading cause of hospitalization and mortality in the U.S. (Kilgore, Patel, Kielhorn, Maya, & Sharma, 2017). Luckily, this condition can be managed through various self-care practices. Although healthcare providers are educating their patients on these self-care practices, patients are making a conscious decision to non-adhere. This phenomenon is known as intelligent non-adherence and is mostly affected by an individual’s level of knowledge, attitudes, beliefs, …

A Sensor-Controlled Digital Game For Heart Failure Self-Care Based On Behavioral Change Frameworks, Kavita Radhakrishnan, Atami Sagna Demain, Christine Julien, Katelyn Leggio, Matthew O'Hair, Emily T Hebért Arsers, Grace Lee, Tom Baranowski

Faculty, Staff and Students Publications

Self-care behaviors are critical to manage the adverse impact of heart failure disease. However, engaging in self-care behaviors such as physical activity or daily weight-monitoring can be difficult due to lack of knowledge or motivation. Digital games can serve as an alternative to traditional patient education to provide information and motivate engagement in critical self-care behaviors. In this paper, we describe a sensor-controlled digital game (SCDG) in which game play is driven by the player's real life self-care behaviors. We also present the design and development of the next iteration of the SCDG based on playtesting results and behavioral theoretical …

INTRODUCTION: Mutations in the LMNA gene, encoding Lamin A/C (LMNA), are established causes of dilated cardiomyopathy (DCM). The phenotype is typically characterized by progressive cardiac conduction defects, arrhythmias, heart failure, and premature death. DCM is primarily considered a disease of cardiac myocytes. However, LMNA is also expressed in other cardiac cell types, including fibroblasts.

AIM: The purpose of the study was to determine the contribution of the fibroblasts to DCM caused by LMNA deficiency.

METHODS AND RESULTS: The Lmna gene was deleted by crossing the platelet-derived growth factor receptor α-Cre recombinase (Pdgfra-Cre) and floxed Lmna (LmnaF/F) …

Advancements In Left Ventricular Assist Devices To Prevent Pump Thrombosis And Blood Coagulopathy, Grainne Malone, Gerges Abdelsayed, Fianait Bligh, Fatma Al Qattan, Saifullah Syed, Prateepan Varatharajullu, Augustin Msellati, Daniela Mwipatayi, Maimoona Azhar, Saulat Hasnain Fatimi

Section of Cardiothoracic Surgery

Mechanical circulatory support (MCS) devices, such as left ventricular assist devices (LVADs) are very useful in improving outcomes in patients with advanced-stage heart failure. Despite recent advances in LVAD development, pump thrombosis is one of the most severe adverse events caused by LVADs. The contact of blood with artificial materials of LVAD pumps and cannulas triggers the coagulation cascade. Heat spots, for example, produced by mechanical bearings are often subjected to thrombus build-up when low-flow situations impair washout and thus the necessary cooling does not happen. The formation of thrombus in an LVAD may compromise its function, causing a drop …

Repurposing Probenecid For The Treatment Of Heart Failure (Re-Prosper-Hf): A Study Protocol For A Randomized Placebo-Controlled Clinical Trial, Jack Rubinstein, Nathan Robbins, Karen Evans, Gabrielle Foster, Kevin Mcconeghy, Toluwalope Onadeko, Julie Bunke, Melanie Parent, Xi Luo, Jacob Joseph, Wen-Chih Wu

Faculty, Staff and Student Publications

BACKGROUND: Improving contractility in heart failure with reduced ejection fraction (HFrEF) has resurfaced as a potential treatment goal. Inotropic therapy is now better understood through its underlying mechanism as opposed to the observed effect of increasing contractility. Calcitropes are a subgroup of inotropes that largely depend on the stimulation of adenylyl cyclase to transform ATP into cyclic adenosine monophosphate (cAMP). At least two clinically relevant calcitropes-istaroxime and probenecid-improve contractility through an increase in systolic intracellular calcium without activating cAMP production. Probenecid, which has been safely used clinically for decades in non-cardiac conditions, has recently been identified as an agonist of …

Heart failure (HF) is a major health problem worldwide. The development of effective drug and/or device therapy is crucial to mitigate the significant morbidity, mortality and healthcare costs associated with HF. The choice of endpoint in clinical trials has important practical and clinical implications. Outcomes of interest including mortality and HF hospitalisations provide robust evidence for regulatory approval granted there is sufficiency of safety data. At the same time, it is important to recognise that HF patients experience significant impairments in functional capacity and quality of life, underscoring the need to incorporate parameters of symptoms and patient-reported outcomes in clinical …

Impact Of Pank1 Deletion On Mitochondrial Acetylation And Cardiac Function During Pressure Overload., Timothy N. Audam

Electronic Theses and Dissertations

Recent studies have associated elevated protein acetylation levels with heart failure in humans. Although mechanisms promoting elevated acetylation levels are not fully known, excess acetyl-CoA may drive enzyme-independent acetylation of cardiac proteins. Accumulation of acetyl-CoA depends on the availability of sufficient CoA, whose production is regulated by pantothenate kinases in the CoA biosynthetic pathway. We show that cardiac proteins are hyperacetylated during heart failure in humans and tested in mice whether limiting CoA abundance would improve ventricular remodeling during pressure overload-induced hypertrophy. We limited cardiac CoA levels by deleting the rate-limiting enzyme in CoA biosynthesis, Pank1 (one of three PANK-encoding …
