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 …

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 …

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 …

Racial Disparities In Intravenous Recombinant Tissue Plasminogen Activator Use Persist At Primary Stroke Centers., Hugo J. Aparicio, Brendan G. Carr, Scott E. Kasner, Michael J. Kallan, Karen C. Albright, Dawn O. Kleindorfer, Michael T. Mullen

Department of Emergency Medicine Faculty Papers

BACKGROUND: Primary stroke centers (PSCs) utilize more recombinant tissue plasminogen activator (rt-PA) than non-PSCs. The impact of PSCs on racial disparities in rt-PA use is unknown.

METHODS AND RESULTS: We used data from the Nationwide Inpatient Sample from 2004 to 2010, limited to states that publicly reported hospital identity and race. Hospitals certified as PSCs by The Joint Commission were identified. Adults with a diagnosis of ischemic stroke were analyzed. Rt-PA use was defined by the International Classification of Diseases, 9th Revision procedure code 99.10. Discharges (304 152 patients) from 26 states met eligibility criteria, and of these 71.5% were …

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 …

Infusion Of Reconstituted High-Density Lipoprotein, Csl112, In Patients With Atherosclerosis: Safety And Pharmacokinetic Results From A Phase 2a Randomized Clinical Trial, Pierluigi Tricoci, Denise M.

Background CSL112 is a new formulation of human apolipoprotein A‐I (apoA‐I) being developed to reduce cardiovascular events following acute coronary syndrome. This phase 2a, randomized, double‐blind, multicenter, dose‐ranging trial represents the first clinical investigation to assess the safety and pharmacokinetics/pharmacodynamics of a CSL112 infusion among patients with stable atherosclerotic disease.

Methods and Results Patients were randomized to single ascending doses of CSL112 (1.7, 3.4, or 6.8 g) or placebo, administered over a 2‐hour period. Primary safety assessments consisted of alanine aminotransferase or aspartate aminotransferase elevations >3× upper limits of normal and study drug–related adverse events. Pharmacokinetic/pharmacodynamic assessments included apoA‐I plasma …

Incidence, In-Hospital Case-Fatality Rates, And Management Practices In Puerto Ricans Hospitalized With Acute Myocardial Infarction, Juan C. Zevallos, Jorge L. Yarzebski, Juan A. Gonzalez, Hector L.

OBJECTIVE: There are extremely limited data on minority populations, especially Hispanics, describing the clinical epidemiology of acute coronary disease. The aim of this study is to examine the incidence rate of acute myocardial infarction (AMI), in-hospital case-fatality rate (CFR), and management practices among residents of greater San Juan (Puerto Rico) who were hospitalized with an initial AMI. METHODS: Our trained study staff reviewed and independently validated the medical records of patients who had been hospitalized with possible AMI at any of the twelve hospitals located in greater San Juan during calendar year 2007. RESULTS: The incidence rate (# per 100,000 …

Myocardial Feature Tracking Reduces Observer-Dependence In Low-Dose Dobutamine Stress Cardiovascular Magnetic Resonance., Andreas Schuster, Matthias Paul, Nuno Bettencourt, Shazia T. Hussain, Geraint Morton, Shelby Kutty, Boris Bigalke, Amedeo Chiribiri, Divaka Perera, Eike Nagel, Philipp Beerbaum

Journal Articles: Cardiology

OBJECTIVES: To determine whether quantitative wall motion assessment by CMR myocardial feature tracking (CMR-FT) would reduce the impact of observer experience as compared to visual analysis in patients with ischemic cardiomyopathy (ICM).

METHODS: 15 consecutive patients with ICM referred for assessment of hibernating myocardium were studied at 3 Tesla using SSFP cine images at rest and during low dose dobutamine stress (5 and 10 μg/kg/min of dobutamine). Conventional visual, qualitative analysis was performed independently and blinded by an experienced and an inexperienced reader, followed by post-processing of the same images by CMR-FT to quantify subendocardial and subepicardial circumferential (Eccendo and …
