A Review Of Neurogenic Stunned Myocardium., Sylvia Biso, Supakanya Wongrakpanich, Akanksha Agrawal, Sujani Yadlapati, Marina Kishlyansky, Vincent M. Figueredo

Department of Medicine Faculty Papers

Neurologic stunned myocardium (NSM) is a phenomenon where neurologic events give rise to cardiac abnormalities. Neurologic events like stroke and seizures cause sympathetic storm and autonomic dysregulation that result in myocardial injury. The clinical presentation can involve troponin elevation, left ventricular dysfunction, and ECG changes. These findings are similar to Takotsubo cardiomyopathy and acute coronary syndrome. It is difficult to distinguish NSM from acute coronary syndrome based on clinical presentation alone. Because of this difficulty, a patient with NSM who is at high risk for coronary heart disease may undergo cardiac catheterization to rule out coronary artery disease. The objective …

Cardiac Arrest Risk Standardization Using Administrative Data Compared To Registry Data., Anne V. Grossestreuer, David F. Gaieski, Michael W. Donnino, Joshua I.M. Nelson, Eric L. Mutter, Brendan G. Carr, Benjamin S. Abella, Douglas J. Wiebe

Department of Emergency Medicine Faculty Papers

BACKGROUND: Methods for comparing hospitals regarding cardiac arrest (CA) outcomes, vital for improving resuscitation performance, rely on data collected by cardiac arrest registries. However, most CA patients are treated at hospitals that do not participate in such registries. This study aimed to determine whether CA risk standardization modeling based on administrative data could perform as well as that based on registry data.

METHODS AND RESULTS: Two risk standardization logistic regression models were developed using 2453 patients treated from 2000-2015 at three hospitals in an academic health system. Registry and administrative data were accessed for all patients. The outcome was death …

Discordance In Investigator-Reported And Adjudicated Sudden Death In Tiospir., Robert A. Wise, Peter R. Kowey, George Austen, Achim Mueller, Norbert Metzdorf, Andy Fowler, Lorcan P Mcgarvey

Department of Medicine Faculty Papers

Accurate and consistent determination of cause of death is challenging in chronic obstructive pulmonary disease (COPD) patients. TIOSPIR (N=17 135) compared the safety and efficacy of tiotropium Respimat 5/2.5 µg with HandiHaler 18 µg in COPD patients. All-cause mortality was a primary end-point. A mortality adjudication committee (MAC) assessed all deaths. We aimed to investigate causes of discordance in investigator-reported and MAC-adjudicated causes of death and their impact on results, especially cardiac and sudden death. The MAC provided independent, blinded assessment of investigator-reported deaths (n=1302) and assigned underlying cause of death. Discordance between causes of death was assessed descriptively (shift …

Rehabilitation Therapy In Older Acute Heart Failure Patients (Rehab-Hf) Trial: Design And Rationale., Gordon R. Reeves, David J. Whellan, Pamela Duncan, Christopher M. O'Connor, Amy M. Pastva, Joel D. Eggebeen, Leigh Ann Hewston, Timothy M. Morgan, Shelby D. Reed, W. Jack Rejeski, Robert J. Mentz, Paul B. Rosenberg, Dalane W. Kitzman

Division of Cardiology Faculty Papers

BACKGROUND: Acute decompensated heart failure (ADHF) is a leading cause of hospitalization in older persons in the United States. Reduced physical function and frailty are major determinants of adverse outcomes in older patients with hospitalized ADHF. However, these are not addressed by current heart failure (HF) management strategies and there has been little study of exercise training in older, frail HF patients with recent ADHF.

HYPOTHESIS: Targeting physical frailty with a multi-domain structured physical rehabilitation intervention will improve physical function and reduce adverse outcomes among older patients experiencing a HF hospitalization.

STUDY DESIGN: REHAB-HF is a multi-center clinical trial in …

Branched Chain Amino Acids Cause Liver Injury In Obese/Diabetic Mice By Promoting Adipocyte Lipolysis And Inhibiting Hepatic Autophagy., Fuyang Zhang, Shihao Zhao, Wenjun Yan, Yunlong Xia, Xiyao Chen, Wei Wang, Jinglong Zhang, Chao Gao, Cheng Peng, Feng Yan, Huishou Zhao, Kun Lian, Yan Lee, Ling Zhang, Wayne Bond Lau, Xin-Liang Ma, Ling Tao

Department of Emergency Medicine Faculty Papers

The Western meat-rich diet is both high in protein and fat. Although the hazardous effect of a high fat diet (HFD) upon liver structure and function is well recognized, whether the co-presence of high protein intake contributes to, or protects against, HF-induced hepatic injury remains unclear. Increased intake of branched chain amino acids (BCAA, essential amino acids compromising 20% of total protein intake) reduces body weight. However, elevated circulating BCAA is associated with non-alcoholic fatty liver disease and injury. The mechanisms responsible for this quandary remain unknown; the role of BCAA in HF-induced liver injury is unclear. Utilizing HFD or …

The Medicine Forum

INTRODUCTION

The American College of Cardiology (ACC) and the American Heart Association (AHA) publ ished pre-operative risk stratification guidelines in 2014. These guidelines have routinely been used by physicians to pre-operatively risk stratify patients. In this case report, a patient was found to have multi-vessel coronary artery disease post-operatively in the setting of unremarkable cardiac work-up preoperatively. This case highlights a limitation of the 2014 ACC/AHA guidelines.

Case Report: Diagnosis Of Dual-Biopsy Negative Severe Cardiac Amyloidosis, Kristin Lohr, Md, Eric Kasprowicz, Md

The Medicine Forum

INTRODUCTION

Amyloidosis is a rare disorder that involves the deposition of misfolded protein in extracellular tissue. Disease manifestations vary depending on the affected organs. Areas most often involved include the kidneys, gastrointestinal tract, heart, nervous system, and musculoskeletal system. The most common type is AL amyloidosis, in which plasma cells produce an abundance of a monoclonal proteins that affect numerous organ systems. A second variety, AA amyloidosis, is associated with inflammatory diseases such as rheumatoid arthritis and inflammatory bowel disease. Finally, a heritable version of amyloidosis mediated by mutations in the transthyretin protein (TTR) has a predilection for deposition in …

Coronary Subclavian Steal Syndrome, Rady Ho, Md, Jonathan A. Dunn, Md

The Medicine Forum

INTRODUCTION

Coronary subclavian steal (CSS) syndrome is a rare complication of coronary artery bypass graft surgery (CABG) involving the left internal mammary artery (LIMA) graft to the left anterior descending (LAD) artery. It results from stenosis of the left subclavian artery proximal to the LIMA, which compromises myocardial blood flow. The incidence of CSS syndrome is between 0.1-3.4% in the United States.1 Most cases occur as a result of long-standing subclavian stenosis due to progres-sion of the stenosis following CABG. We report a case of CSS syndrome, which presented as a non-ST elevation myocardial infarction (NSTEMI).

Allergic Inflammatory Mediated Coronary Artery Vasospasm: A Case Report Of Kounis Syndrome, Jonathan Hullman, Ms4, Jaehee Kim, Md, Gregary D. Marhefka, Md, Facc, Facp

The Medicine Forum

INTRODUCTION

Kounis syndrome is an acute coronary syndrome occurring secondary to an anaphylactic reaction. A wide variety of triggers such as drugs and environmental exposures have been described for the so-called allergic myocardial infarction. The pathophysiology of Kounis syndrome is thought to be due to the release of inflammatory mediators such as histamine and cytokines by mast cells and eosinophils resulting in either coronary vasospasm, myocardial infarction or stent thrombosis.

Squamous Cell Carcinoma Metastatic To The Heart Mimicking St-Elevation Myocardial Infarction, Jason Chen, Md, Colin Craft, Md, Andrew W. Panakos, Md, Gregary D. Marhefka, Md, Facc, Facp

The Medicine Forum

INTRODUCTION

Heart disease remains the leading cause of mortality in the United States, accounting for about one quarter of all deaths in 20131. Acute ischemic heart disease is a major subpopulation of this group, and typically presents with characteristic electrocardiographic (EKG) changes. The most concerning of these findings are ST-elevations, as ST Elevation Myocardial Infarction (STEMI) typically indicates the need for emergent reperfusion therapy because 30-day mortality of untreated STEMI is approximately 10-15% versus 5% in treated cases2. As a result, clinicians are taught to recognize the symptoms and signs of myocardial ischemia and STEMI in order to achieve timely …

Childhood Psychosocial Determinants Of Cardiovascular Health, Samuel S. Gidding, Erica D. Sood

Department of Medicine Faculty Papers

Understanding risk and protective factors that impact cardiovascular health is of utmost importance. There is ample evidence that cardiovascular health begins in childhood, tracks over time, and is subject to adverse social influences. This paper reviews key studies examining the relations of psychosocial factors in childhood to cardiovascular health in adulthood. The existing literature provides evidence for both individual and cumulative effects of childhood psychosocial factors on adult cardiovascular health across the population, although the specific mechanisms underlying these relationships are not yet fully understood. This paper also includes a discussion of evidence-based strategies for prevention and treatment of childhood …

BACKGROUND: Nitrates are commonly prescribed to enhance activity tolerance in patients with heart failure and a preserved ejection fraction. We compared the effect of isosorbide mononitrate or placebo on daily activity in such patients.

METHODS: In this multicenter, double-blind, crossover study, 110 patients with heart failure and a preserved ejection fraction were randomly assigned to a 6-week dose-escalation regimen of isosorbide mononitrate (from 30 mg to 60 mg to 120 mg once daily) or placebo, with subsequent crossover to the other group for 6 weeks. The primary end point was the daily activity level, quantified as the average daily accelerometer …

Notching Early Repolarization Pattern In Inferior Leads Increases Risk Of Ventricular Tachyarrhythmias In Patients With Acute Myocardial Infarction: A Meta-Analysis., Zhiwei Zhang, Konstantinos P Letsas, Yajuan Yang, Panagiotis Korantzopoulos, Guangping Li, Gan-Xin Yan, Tong Liu

Department of Medicine Faculty Papers

The aim of this of this meta-analysis was to examine the potential association between certain early repolarization (ER) characteristics and ventricular tachyarrhythmias (VTAs) in patients with acute myocardial infarction (AMI). We searched PubMed, Embase and Web of Science databases for records published until December 2014. Of the 658 initially identified records, 7 studies with a total of 1,565 patients (299 with ER and 1,266 without ER) were finally analyzed. Overall, patients with ER displayed a higher risk of VTAs following AMI compared to patients without ER [odds ratio (OR): 3.75, 95% CI: 2.62-5.37, p < 0.00001]. Subgroup analyses showed that the diagnosis of ER prior to AMI onset is a better predictor of VTAs (OR: 5.70, p < 0.00001) compared to those diagnosed after AMI onset (OR: 2.60, p = 0.00001). Remarkably, a notching morphology was a significant predictor of VTAs compared to slurring morphology (OR: 3.85, p = 0.002). Finally, an inferior ER location (OR: 8.85, p < 0.00001) was significantly associated with increased risk of VTAs in AMI patients. In conclusion, our meta-analysis suggests that ER pattern is associated with greater risk of VTAs in patients with AMI. A notched ER pattern located in inferior leads confers the highest risk for VTAs in AMI.

Right Ventricular Dysfunction After Resuscitation Predicts Poor Outcomes In Cardiac Arrest Patients Independent Of Left Ventricular Function., Vimal Ramjee, Anne V. Grossestreuer, Yuan Yao, Sarah M. Perman, Marion Leary, James N. Kirkpatrick, Paul R. Forfia, Daniel M. Kolansky, Benjamin S. Abella, David F. Gaieski

Department of Emergency Medicine Faculty Papers

OBJECTIVE: Determination of clinical outcomes following resuscitation from cardiac arrest remains elusive in the immediate post-arrest period. Echocardiographic assessment shortly after resuscitation has largely focused on left ventricular (LV) function. We aimed to determine whether post-arrest right ventricular (RV) dysfunction predicts worse survival and poor neurologic outcome in cardiac arrest patients, independent of LV dysfunction.

METHODS: A single-center, retrospective cohort study at a tertiary care university hospital participating in the Penn Alliance for Therapeutic Hypothermia (PATH) Registry between 2000 and 2012.

PATIENTS: 291 in- and out-of-hospital adult cardiac arrest patients at the University of Pennsylvania who had return of spontaneous …

Whellan, Barbara Riegel, Wayne C. Levy

Department of Medicine Faculty Papers

BACKGROUND: Heart failure disease management programs can influence medical resource use and quality-adjusted survival. Because projecting long-term costs and survival is challenging, a consistent and valid approach to extrapolating short-term outcomes would be valuable.

METHODS: We developed the Tools for Economic Analysis of Patient Management Interventions in Heart Failure Cost-Effectiveness Model, a Web-based simulation tool designed to integrate data on demographic, clinical, and laboratory characteristics; use of evidence-based medications; and costs to generate predicted outcomes. Survival projections are based on a modified Seattle Heart Failure Model. Projections of resource use and quality of life are modeled using relationships with time-varying …

Saving Life And Brain With Extracorporeal Cardiopulmonary Resuscitation: A Single-Center Analysis Of In-Hospital Cardiac Arrests., Graham Peigh, Nicholas C. Cavarocchi, Hitoshi Hirose

Department of Surgery Faculty Papers

OBJECTIVE: Despite advances in medical care, survival to discharge and full neurologic recovery after cardiac arrest remains less than 20% after cardiopulmonary resuscitation. An alternate approach to traditional cardiopulmonary resuscitation is extracorporeal cardiopulmonary resuscitation, which places patients on extracorporeal membrane oxygenation during cardiopulmonary resuscitation and provides immediate cardiopulmonary support when traditional resuscitation has been unsuccessful. We report the results from extracorporeal cardiopulmonary resuscitation at the Thomas Jefferson University.

METHODS: Between 2010 and June 2014, 107 adult extracorporeal membrane oxygenation procedures were performed at the Thomas Jefferson University. Patient demographics, survival to discharge, and neurologic recovery of patients who underwent extracorporeal …

Simple New Risk Score Model For Adult Cardiac Extracorporeal Membrane Oxygenation: Simple Cardiac Ecmo Score., Graham Peigh, Nicholas Cavarocchi, Scott W. Keith, Hitoshi Hirose

Department of Surgery Faculty Papers

BACKGROUND: Although the use of cardiac extracorporeal membrane oxygenation (ECMO) is increasing in adult patients, the field lacks understanding of associated risk factors. While standard intensive care unit risk scores such as SAPS II (simplified acute physiology score II), SOFA (sequential organ failure assessment), and APACHE II (acute physiology and chronic health evaluation II), or disease-specific scores such as MELD (model for end-stage liver disease) and RIFLE (kidney risk, injury, failure, loss of function, ESRD) exist, they may not apply to adult cardiac ECMO patients as their risk factors differ from variables used in these scores.

METHODS: Between 2010 and …
