Statistics Faculty Publications

OBJECTIVES: Cardiovascular complications became a notable cause of morbidity and mortality in patients with lupus as therapeutic advancements became more efficient at managing other complications. The Appalachian community in Kentucky has a higher prevalence of traditional cardiovascular risk factors, predisposing them to cardiovascular events. Namely, the mean body mass index of the members of the Kentucky Appalachian community was reported at 33 kg/m² and 94.3% of male members of this community use tobacco. We sought to identify risk factors that predispose patients with lupus to cardiovascular morbidities and examine the effect of immunomodulatory drugs.

Prospective, observational data was collected in two cases in this proof-of-concept study. An assessment physician evaluated the donor heart remotely, and …

Removal Of Impella In The Setting Of Left Ventricular Thrombus: A Potential Indication For Cerebral Embolic Protection Devices, Miro Asadourian, Avinash Sharma, Richard Kiel, Felice Lin, Manminder Bhullar

The VAD Journal

Successful percutaneous mechanical circulatory support (MCS) has been used for acute stabilization of cardiogenic shock (CS). Improved survival outcomes have been observed in patients with CS from an acute myocardial infarction (AMI) who undergo implantation of left ventricular (LV) to ascending aorta rotodynamic pumps, such as the Impella® device (Abiomed). However, thrombotic events are a known complication of such devices in poor flow states such as CS. There is limited evidence regarding the management of patients who develop an LV thrombus after Impella insertion. Currently, the Sentinel cerebral protection system (SCPS, Boston Scientific) is the only FDA-approved device for cerebral …

Early Systolic Dysfunction And Impact Of Gene Mutation Severity In Marfan Syndrome, Aaron Clem, Lois J. Starr, David Danford, Mary Craft, Ling Li, Jason Christensen, Anji Yetman

Child Health Research Institute Pediatric Research Forum

Background

Marfan syndrome is caused by a mutation in the fibrillin-1 gene that manifests with a variety of features including aortic root dilation. Recent research has identified a primary cardiomyopathy in patients with Marfan syndrome, hypothesized to be due to the presence of abnormal fibrillin-1 in the myocardium. Controversy over the nature and significance of this cardiomyopathy remains. Echocardiographic measurement of the first-phase of ejection (defined as the beginning of systole to peak aortic valve flow) may be more sensitive to systolic dysfunction and provide useful clinical information. The purpose of this study is to:

1. Assess systolic dysfunction in patients …

Constrictive Pericarditis After Repair Of A Ruptured Sinus Of Valsalva, Sarah Studyvin, Sanket Shah

Posters

Background: Constrictive pericarditis (CP) is a rare complication of cardiac surgery. We report a patient who developed CP after ruptured sinus of Valsalva (RSOV) repair.

Case: A 23-year-old male presented with severe exertional dyspnea one year after RSOV repair. Echocardiogram showed thickened pericardium, ventricular septal bounce (Fig 1A), left atrial enlargement, diastolic hepatic flow reversal (Fig 1B), and trivial mitral regurgitation without stenosis. He underwent cardiac catheterization, which revealed elevated filling pressures (RVEDP 16 mmHg, LVEDP 18 mmHg), RVEDP/RVSP ratio < 0.5, and a low cardiac index (1.65 L/min/m2). Cardiac MRI on the same day confirmed pericardial thickening (Fig D) with paradoxic septal motion, dilated pulmonary veins (Fig 1F) and retrograde flow in the SVC.

Decision‐making: Pericardiectomy of thickened and adherent pericardium was performed without the use of cardiopulmonary bypass. The central venous pressure decreased …

Pharmacists’ Role In The Management Of Patients Receiving Dual Or Triple Antithrombotic Therapy, Laura Neubauer, Radhan Gopalani, Kristen De Almeida

All Publications

Purpose: Patients on dual and triple antithrombotic therapy present the therapeutic dilemma of mitigating bleed risk while sustaining antithrombotic efficacy. Lack of literature and variability in existing published guidance potentiates inconsistent management of these patients. Furthermore, suboptimal dosing of direct oral anticoagulants is relatively common. One study reported as high as 43% of patients receive higher and 13% receive lower than clinically indicated doses. These findings were associated with a significantly increased risk of major bleeding and incidence of stroke, thus highlighting the importance of selecting an ideal regimen. The purpose of this project is to highlight pharmacists’ role in …

Identifying The Cardiovascular Effects Of Multiple Pollutants., Katlyn Elizabeth Mcgraw

Electronic Theses and Dissertations

Cardiovascular disease (CVD) is the leading cause of death from environmental exposures. Although exposure to PM_2.5 is an established risk factor for CVD, the contribution of other hazardous pollutant exposure to CVD is less clear. Overall, this work aimed to examine the effect of pollutants with lesser documented effects on cardiovascular disease using a multi-pronged approach to exposure assessment. The three aims were to examine the relationship between county-level toxic chemical releases and CVD mortality in the contiguous United States between 2002 and 2012, to assess the relationship between individual-level VOC metabolites and vascular function, and to build multipollutant …

Hemodynamic Management Of Patients With Ejection Fraction < 50% Undergoing Pulmonary Vein Ablation, Aaron B. Hesselson, Heather Hesselson

Internal Medicine Faculty Publications

There is no consensus regarding optimal methodology forblood pressure monitoring inpatients with a depressed ejection fraction undergoingcatheter ablationfor atrial fibrillation. Our goalswere to determine ifhemodynamicmanagementdifferences exist during radiofrequency ablation for atrial fibrillation in patients with and without an ejection fraction< 50%, and whether management was influenced by the utilization of invasive arterial blood pressure monitoring. This single-center trial retrospectively compared blood pressure management during catheterablation of atrial fibrillationin all patients with an ejection fraction< 50% over a 2-year span (n=44), and compared to an age-matched cohort with preserved ejection fraction ablated over the same span in time (n=44). Blood pressure was not significantly managed differently between the groups, and did not appear to be influenced by the use of invasive arterial blood pressure monitoring. Hemodynamic management is similar across the spectrum of ejection fraction, regardless of invasive arterial blood pressure monitoring, which challenges the need for invasive arterial blood pressure monitoringduringcatheter ablation ofatrial fibrillationin left ventricular systolic dysfunction.

Perivascular Adipose Tissue In Relation To Diet, Thermogenesis And Cardiovascular Health, Ginger Paquette, Caitlin Stieber, Ashely Soucy, Benjamin Tero, Lucy Liaw

Thinking Matters Student Research Symposium

Adipose tissue is a diverse and crucial component to vascular health due to its role in energy storage and heat production. The primary function of white adipose tissue (WAT) is energy storage while the function of mitochondria-rich brown adipose tissue (BAT) is heat production. Perivascular adipose tissue (PVAT), which surrounds blood vessels, contains both WAT and BAT adipocytes. Dietary calorie restriction is associated with increased lifespan with decreased adiposity. Increased prevalence of WAT-like PVAT, due to high-fat diets and obesity, leads to increased metabolic disfunction and cardiovascular-disease. We used a calorie-restriction model in C57BL6/J mice to test the hypothesis that …

The Role Of Implantable Cardioverter Defibrillators For The Prevention Of Ventricular Arrhythmia In Left Ventricular Assist Device Recipients, Nikhil Reddy, Cristina Ortiz, Toshimasa Okabe, Muhammad Afzal, Mohamed H. Derbala, Asvin Ganapathi, Sakima Smith

Medical Student Research Symposium Abstracts and Posters

Advanced heart failure represents a significant strain on our health care system and is associated with increased morbidity and mortality. New device therapies, including left ventricular assist device (LVAD) implantation, have transformed management as both a destination therapy and as a bridge to transplantation. Although LVADs have improved patient outcomes, arrhythmias represent a significant and costly complication of this therapy. In recent years, implantable cardioverter-defibrillators (ICDs) have been developed to reduce the incidence of lethal arrhythmia. However, a gap in the literature exists for both guidelines in prevention of early ventricular arrhythmia (VA) in LVAD recipients and the effectiveness of …

Methamphetamine Associated Cardiomyopathy And Fatal Thrombus Formation, Kaitlynne Pak, Sanuri Gunawardena, Ericson Torralba, Juan Linares, Damian Valencia, Nathaniel Dittoe

Medical Student Research Symposium Abstracts and Posters

Stimulant abuse is a rapidly growing epidemic both in the United States, and around the world. Reports show that nearly 4.7 million Americans have tried methamphetamines at least once. It is known that methamphetamines and related compounds significantly increase cardiovascular morbidity and mortality. Substance-related chronic inflammation and tissue fibrosis can cause irreversible cardiac structural changes, leading to conditions like methamphetamine-associated dilated cardiomyopathy (MACM). Left ventricular dilation results in hemodynamic flow disturbances, which promote turbulent blood flow and stagnation. Furthermore, the sympathomimetic effects of methamphetamines also disrupt pathways in coagulation homeostasis, providing further incitement of thrombus formation. This unstable catecholamine driven …

Heyde’S Syndrome: An Enigma, Fayaz Mohammed Khazi, Nayyer R. Siddiqi, Yehia Mohamed Karaly, Obaid Aljassim, Zohair Y. Al-Halees

Journal of the Saudi Heart Association

Heyde's syndrome (HS) is described as the association between recurrent bleeding from angiodysplasia of the gastrointestinal tract and aortic stenosis. Aortic valve replacement has been reported to stop the bleeding. In unfit patients, the options available are interventional or conservative management. We hereby report an elderly obese patient with severe comorbidity with complicated HS involving a narrow aortic root. She underwent left ventricular outlet myomectomy and aortic root replacement to promote better forward flow and prevent restenosis and recurrence of symptoms. She was discharged home symptom-free despite being on coumadin anticoagulants.
