The Role Of Mitochondrial Pyruvate Carrier 1 (Mpc1) In Heart Failure And Its Implications For Cardiac Recovery, Obadiah Issachar Kirk Jan 2020

The Role Of Mitochondrial Pyruvate Carrier 1 (Mpc1) In Heart Failure And Its Implications For Cardiac Recovery, Obadiah Issachar Kirk

Mahurin Honors College Capstone Experience/Thesis Projects

Heart failure (HF) is a complex syndrome with high mortality rates around the world. HF also has diverse etiology as many things contribute such as hypertension, obesity, coronary artery disease, inflammation, and cardiac arrhythmias. Studies have shown that unloading of a failing heart with a left ventricular assist device (LVAD) can lead to cardiac recovery in a subpopulation of individuals with advanced HF. RNA-sequencing and protein expression analysis of myocardial tissue from HF patients who underwent the LVAD implant and heart transplant indicated that subpopulation of HF patients who responded to LVAD unloading had significantly lower levels of mitochondrial pyruvate …

Evaluating Cardiac Anatomy As A Predictor For Success After Pulmonary Vein Isolation For The Treatment Of Atrial Fibrillation, Paul Richter, Evan Rochlis, Ethan Halpern Jan 2020

Evaluating Cardiac Anatomy As A Predictor For Success After Pulmonary Vein Isolation For The Treatment Of Atrial Fibrillation, Paul Richter, Evan Rochlis, Ethan Halpern

Phase 1

Introduction: Atrial Fibrillation is a condition characterized by the production of ectopic beats by the heart. One common treatment for Atrial Fibrillation is catheter guided pulmonary vein isolation (PVI), however this treatment is only effective in around 60-70% of the population. Our research hopes to elucidate a link between cardiac anatomy and successful treatment of A-fib by pulmonary vein isolation.

Methods: The medical records for 78 consecutive patients who underwent PVI for atrial fibrillation at Jefferson from July 2013 to March 2016 were gathered. Included in these charts were ECG-gated cardiac CT angiogram and two-year follow up history. Different variables …

State-Level Cpr Education Legislation Associated With Higher Survival After Out-Of-Hospital Cardiac Arrest In Older Adults, Megan Barnes, David G. Buckler, Tyler D. Alexander, Marissa Lang, Alexis Zebrowski, Douglas J. Wiebe, Benjamin S. Abella, Brendan G. Carr

Phase 1

Introduction: State-level legislation requiring CPR education prior to high school graduation is associated with an increased likelihood of community-level CPR training. CPR Legislation has also been shown to be associated with increased bystander CPR. We hypothesized that states with CPR Legislation would be associated with higher survival following out-of-hospital cardiac arrest (OHCA).

Methods: Utilizing 2014 Medicare Claims data for emergency department visits and inpatient stays, we identified OHCA via ICD-9-CM code. CPR Legislation data was collected through online statute review. Exposure to CPR Legislation was assessed using the patient state of residence. All disposition categories were considered survival to discharge …


Investigating The Effects Of Brainstem Neuronal Adaptation On Cardiovascular Homeostasis., James H Park, Jonathan Gorky, Babatunde Ogunnaike, Rajanikanth Vadigepalli, James S Schwaber Jan 2020

Investigating The Effects Of Brainstem Neuronal Adaptation On Cardiovascular Homeostasis., James H Park, Jonathan Gorky, Babatunde Ogunnaike, Rajanikanth Vadigepalli, James S Schwaber

Articles, Abstracts, and Reports

Central coordination of cardiovascular function is accomplished, in part, by the baroreceptor reflex, a multi-input multi-output physiological control system that regulates the activity of the parasympathetic and sympathetic nervous systems via interactions among multiple brainstem nuclei. Recent single-cell analyses within the brain revealed that individual neurons within and across brain nuclei exhibit distinct transcriptional states contributing to neuronal function. Such transcriptional heterogeneity complicates the task of understanding how neurons within and across brain nuclei organize and function to process multiple inputs and coordinate cardiovascular functions within the larger context of the baroreceptor reflex. However, prior analysis of brainstem neurons revealed …

Evaluating The Impact Of Kardiamobile On Healthcare Expenditures, Christopher Gerace, Mph, Daniel Frisch, Md Jan 2020

Evaluating The Impact Of Kardiamobile On Healthcare Expenditures, Christopher Gerace, Mph, Daniel Frisch, Md

Phase 1

Background: KardiaMobile is a mobile ECG device, with smartphone connectivity, that is able to detect atrial fibrillation (a-fib). The device captures a 30 second reading and an algorithm differentiates a-fib from sinus rhythm. The mobile application can alert the user to an a-fib reading and also send the ECG output to their personal physician. By monitoring a-fib without accessing traditional care, KardiaMobile has the potential to reduce healthcare costs for patients with a-fib. This study looked to evaluate the effect of KardiaMobile on healthcare utilization for patients with suspected or diagnosed a-fib and who see a clinical cardiac electrophysiologist.

Evaluation Of Ventricular Repolarization In Patients Undergoing Cardiac Resynchronization Therapy (Crt) Using Two Modalities: Conventional Biventricular Pacing Vs. His-Bundle Pacing, Anshul Gupta, Behzad B. Pavri, Md, Fhrs Jan 2020

Evaluation Of Ventricular Repolarization In Patients Undergoing Cardiac Resynchronization Therapy (Crt) Using Two Modalities: Conventional Biventricular Pacing Vs. His-Bundle Pacing, Anshul Gupta, Behzad B. Pavri, Md, Fhrs

Phase 1

Introduction:

Permanent His-bundle pacing (HBP) is being used as an alternative to biventricular pacing (BiVP) for CRT. HBP preserves the physiologic pattern of ventricular activation and markedly reduces ventricular dyssynchrony. While ventricular depolarization with HBP vs. BiVP has been studied, the effects of the 2 modalities on repolarization have not been compared. The purpose of this study was to compare ventricular repolarization in patients with HBP and BiVP. We hypothesize that HBP provides more physiologic repolarization as compared to BiVP.

Methods: ECG repolarization parameters were analyzed in patients who underwent HBP and BiVP using the first available ECG post implant. …


Pilot Evaluation Of The Usability And Utility Of A Wearable Technology To Monitor And Evaluate Health Condition, Drew Nielsen, David Shipon, Md, Facc, Facp Jan 2020

Pilot Evaluation Of The Usability And Utility Of A Wearable Technology To Monitor And Evaluate Health Condition, Drew Nielsen, David Shipon, Md, Facc, Facp

Phase 1

Introduction: Cardiac rehabilitation programs have particularly poor attrition and rehospitalization from cardiac-related events is a large burden on the medical system, as 8.9% of patients who have acute MI are rehospitalized within one year. External barriers may exist that prevent patients from adequately completing in-house cardiac rehabilitation, which makes them strong candidates for a home-based rehab program (HBCR). Previous randomized trials have generated evidence that HBCR can achieve similar cardiac improvements in 3- 12-month clinical outcomes. With the large-scale adoption of wearable technologies, with an estimated 8.2 million devices owned by individuals over 55, we have an opportunity to incorporate …


The Role Of Interleukin-18 In Myocardial Ischemia/Reperfusion, Yogesh Dhakal Jan 2020

The Role Of Interleukin-18 In Myocardial Ischemia/Reperfusion, Yogesh Dhakal

Theses and Dissertations

Acute Myocardial Infarction (AMI) is one of the leading causes of morbidity for cardiovascular diseases (CVDs) in the western world. While mortality rates for AMI has reduced in the last 20 years due to advancements in clinical interventions, patients who have an AMI are significantly more likely to develop heart failure (HF) in the following years. Reperfusion of the ischemic tissue is a necessary procedure to restore blood delivery to cardiomyocytes, minimize myocardial dysfunction, and reduce infarct size. Still, the step of reperfusion itself induces myocardial damage in a phenomenon known as reperfusion injury. Considering that the degree of myocardial …

Cardiac Risk Factors Predicting 30/90 Day Readmission Rates In Lumbar Decompression Surgeries, Blake Nourie, Kevin Xiao, Joseph Bechay, Dhruv K.C. Goyal

Phase 1

Preoperative cardiopulmonary disease is known to be a risk factor for perioperative complications in deformity surgery and lumbar fusion procedures, however there is a lack of literature evaluating cardiac risk factors and their influence on readmission rates following lumbar decompression surgery. We want to determine whether preoperative cardiac risk factors influenced the 30 and 90-day readmission rates in patients undergoing lumbar decompression surgery. Patient charts from Rothman Institute between were reviewed for history of preoperative cardiac risk factors such as coronary artery disease, congestive heart failure, myocardial infarction, stroke, cardiac catheterization, stent placement, coronary artery bypass graft, aspirin and/or clopidogrel …

Effect Of Contrast-Enhanced Echocardiograms On The Prognosis Of Infective Endocarditis, D. Arias, E. Halpern, F. Forsberg, J. R. Eisenbrey

Phase 1

Objective - Infective endocarditis (IE) is an infectious disease of the cardiac valves where bacteria colonize the valves; typically, via the formation of vegetations. Recent research has shown that the microbubbles in a contrast-enhanced ultrasound (CEUS) examination can move and dislodge bacterial vegetations in vitro. This study investigated whether CEUS resulted in faster resolution of IE in vivo by dislodging the vegetations.

Methods - This IRB approved retrospective study reviewed 36 patients who were diagnosed with IE via echocardiography. Data was sourced from patients within the Jefferson University Hospital’s Cardiology EMR system by searching for contrast and vegetation from …

In Adult Patients 60+ Y.O. With Aaa, Would (F)Evar Lead To Least Amount Of Post-Operative Complications Than Traditional Osr?, Sandra Yoo

Capstone Showcase

INTRODUCTION: An abdominal aortic aneurysm (AAA) is a permanent ballooning of the abdominal aorta greater than 3cm in diameter. A small AAA is often asymptomatic. However, as time passes the risk of rupture increases as the diameter of the aneurysm widens. This can ultimately lead to massive internal bleeding and fatality. Surgery is the most common course of treatment for AAA. Most patients will undergo traditional open surgery, but this is often associated with prolonged in-hospital recovery and is contraindicated in an aging population that have a higher prevalence of comorbidities. With this in thought, some clinicians have been turning …

Abstract

Introduction: Systolic heart failure is a chronic condition in which there is a decrease in the heart’s ability to pump blood to the body. While there are several treatments for the symptoms of heart failure, the only curative treatment for most causes of chronic heart failure is a heart transplant. Due to the limited number of heart donors, 72.2% of patients in need of a heart transplant in 2017 spent up to 2 years waiting for a transplant. Mechanical circulatory support has been used to increase patient survival to transplantation. In the past, these machines were external devices that …

Coagulopathy often develops soon after acute traumatic brain injury and its cause remains poorly understood. We have shown that injured brains release cellular microvesicles that disrupt the endothelial barrier and induce consumptive coagulopathy. Morphologically intact extracellular mitochondria accounted for 55.2% of these microvesicles, leading to the hypothesis that these extracellular mitochondria are metabolically active and serve as a source of oxidative stress that activates platelets and renders them procoagulant. In testing this hypothesis experimentally, we found that the extracellular mitochondria purified from brain trauma mice and those released from brains subjected to freeze-thaw injury remained metabolically active and produced reactive …

Lisinopril-Induced Angioedema In A Patient With Plasma Prekallikrein Deficiency, Swapan K Dasgupta, Stefanie Rivera, Perumal Thiagarajan

Faculty, Staff and Students Publications

Angiotensin-converting enzyme (ACE) inhibitors are extensively prescribed to treat patients with hypertension, congestive heart failure, and diabetic nephropathy. A small fraction of these patients (approximately 0.7%) develop angioedema, manifested by swelling of the lips and oropharynx. Angioedema of oropharynx is a medical emergency that can lead to asphyxiation and death. The angioedema is due to bradykinin generated from high molecular weight kininogen by kallikrein, which is derived from plasma prekallikrein by action of the factor XIIa, factor Xia, or prolylcarboxypeptidase. Bradykinin induces vasodilation and increased vascular permeability. ACE is the major degrading enzyme of bradykinin in the intravascular department. ACE …
