Perioperative Use Of Renin-Angiotensin System Inhibitors And Outcomes In Patients Undergoing Cardiac Surgery., Qian Ding, Zugui Zhang, Hong Liu, Huang Nie, Mark Berguson, Jordan E. Goldhammer, Nilas Young, Douglas Boyd, Rohinton Morris, Jianzhong Sun

Department of Anesthesiology Faculty Papers

It remains disputable about perioperative use of renin-angiotensin system inhibitors (RASi) and their outcome effects. This multicenter retrospective cohort study examines association between use of perioperative RASi and outcomes in patients undergoing coronary artery bypass graft and/or valve surgery. After the exclusion, the patients are divided into 2 groups with or without preoperative RASi (PreRASi, n = 8581), or 2 groups with or without postoperative RASi (PostRASi, n = 8130). With using of propensity scores matching to reduce treatment selection bias, the study shows that PreRASi is associated with a significant reduction in postoperative 30-day mortality compared with without one …

Improving Patient Experience And Education By Leveraging Technology, Cathy Palleschi, Wendy Osgood, Mark Parker, Cecilia Inman, Alicia Russell, Eileen Shanahan, Erin Pappal

Operations Transformation

It is estimated that 65% of the population are visual learners. With that in mind, a team of cardiac nurses in a large academic tertiary hospital developed a quality improvement project to hopefully improve patient engagement as well the patients’ perception that the nurses explained things in a manner that they could understand.

Baseline patient survey scores for the question, “Nurses Explained Things In A Way That I Understand”, were under the 75^thpercentile for a period of 9 months. A root cause analysis was conducted and it demonstrated numerous reasons for this score.

Several countermeasures were instituted to …

Nuclear Receptor Subfamily 4 Group A Member 2 Inhibits Activation Of Erk Signaling And Cell Growth In Response To Β-Adrenergic Stimulation In Adult Rat Cardiomyocytes, Sadia Ashraf, Yassmin K Hegazy, Romain Harmancey

Faculty, Staff and Student Publications

Sustained elevation of sympathetic activity is an important contributor to pathological cardiac hypertrophy, ventricular arrhythmias, and left ventricular contractile dysfunction in chronic heart failure. The orphan nuclear receptor NR4A2 is an immediate early-response gene activated in the heart under β-adrenergic stimulation. The goal of this study was to identify the transcriptional remodeling events induced by increased NR4A2 expression in cardiomyocytes and their impact on the physiological response of those cells to sustained β-adrenergic stimulation. Treatment of adult rat ventricular myocytes with isoproterenol induced a rapid (<4 >h) increase in NR4A2 levels that was accompanied by a transient (<24 >h) increase …

Manuscripts, Articles, Book Chapters and Other Papers

PURPOSE: Poor adherence to dietary/behaviour modifications as interventions for hypercholesterolemia in paediatric patients often necessitates the initiation of statin therapy. The aim of this study was to develop a joint population pharmacokinetic model for simvastatin and four metabolites in children and adolescents to investigate sources of variability in simvastatin acid exposure in this patient population, in addition to SLCO1B1 genotype status.

METHODS: Plasma concentrations of simvastatin and its four metabolites, demographic and polymorphism data for OATP1B1 and CYP3A5 were analysed utilising a population pharmacokinetic modelling approach from an existing single oral dose (10 mg < 17 years and 20 mg ≥ 18 years) pharmacokinetic dataset of 32 children and adolescents.

RESULTS: The population PK model included …

Mechanisms Of Simvastatin Myotoxicity: The Role Of Autophagy Flux Inhibition., Arya Emami, Shahla Shojaei, Simone C.

Center for Translational Medicine Faculty Papers

Statins are some of the most widely used drugs worldwide, but one of their major side effects is myotoxicity. Using mouse myoblast (C2C12) and human alveolar rhabdomyosarcoma cell lines (RH30) in both 2-dimensional (2D) and 3-dimensional (3D) cell culture, we investigated the mechanisms of simvastatin's myotoxicity. We found that simvastatin significantly reduced cell viability in C2C12 cells compared to RH30 cells. However, simvastatin induced greater apoptosis in RH30 compared to C2C12 cells. Simvastatin-induced cell death is dependent on geranylgeranyl pyrophosphate (GGPP) in C2C12 cells, while in RH30 cells it is dependent on both farnesyl pyrophosphate (FPP) and GGPP. Simvastatin inhibited …

Manuscripts, Articles, Book Chapters and Other Papers

Purpose: Single site ventricular pacing can result in electromechanical dyssynchrony and LV dysfunction. A classic pattern by strain echocardiography pattern analysis has been defined that specifically identifies electromechanical dyssynchrony that leads to LV dysfunction in other populations. Our purpose is to evaluate for the presence of the classic pattern and an association with LV dysfunction in asymptomatic young subjects with chronic pacing.

Methods: Inclusion criteria of non-surgical 2nd or 3rd degree AV block, normal cardiac anatomy, chronic ventricular pacing (> 95% of beats) and a quality 4-chamber apical image were met by 24 retrospective and 10 prospectively enrolled subjects. Global …

Developing An Evidence-Based Discharge Process For Patients On A Cardiac/Renal Acuity-Adaptable Inpatient Unit, Tami Gallagher

Master's Projects

Introduction: Readmissions continue to negatively impact patient outcomes and create a significant financial burden. Regardless of efforts to reduce readmission rates, the cost of readmission continues to increase.

Clinical Problem: All-cause, 30-day readmission rates on a cardiac/renal acuity-adaptable inpatient nursing unit ranged from 11% to 33% from July to December 2018 for patients diagnosed with COPD, AMI, HF, and sepsis. The readmission rate for the organization was 16.2% in September 2018 with a target goal of 14.8%.

Project Aim: To use quality improvement tools and an interdisciplinary team to implement the teach-back method during discharge education and a discharge preparedness …

Severity Of Chest Pain Among Acute Myocardial Infarction Patients With Diagonal Branch Vessel Disease: A Pilot Study, Nasir Rahman, Azmina Artani, Farhala Mari Baloch, Bilal Hussain

Section of Cardiology

Introduction: Acute myocardial infarction (AMI) patients present with variable clinical manifestations such as shortness of breath, nausea, etc. among which chest pain is the most common. Previous studies have reported that the clinical presentation of AMI patients with branch vessel disease is indistinguishable from epicardial coronary vessel disease. However, our experience suggests patients with branch vessel disease experience severe chest pain, especially those with a diagonal branch. Therefore, we aim to study the association of chest pain severity with isolated diagonal branch vessel disease as a culprit vessel in AMI patients.

Methods: It is a retrospective case-control design, where 10 …

Prasugrel is a thienopyridine that was approved by the US Food and Drug Administration (FDA) in combination with aspirin for the reduction of thrombotic events as well as stent thrombosis in patients with ACS who undergo PCI. This retrospective study aims to assess the frequency of inappropriate use of prasugrel and to emphasize that prasugrel still needs more attention as inappropriate use may result in significant morbidity.

Functionalization Of Cd36 Cardiovascular Disease And Expression Associated Variants By Interdisciplinary High Throughput Analysis., Namrata Madan, Andrew R. Ghazi, Xianguo Kong, Edward S. Chen, Chad A. Shaw, Leonard C. Edelstein

Department of Medicine Faculty Papers

CD36 is a platelet membrane glycoprotein whose engagement with oxidized low-density lipoprotein (oxLDL) results in platelet activation. The CD36 gene has been associated with platelet count, platelet volume, as well as lipid levels and CVD risk by genome-wide association studies. Platelet CD36 expression levels have been shown to be associated with both the platelet oxLDL response and an elevated risk of thrombo-embolism. Several genomic variants have been identified as associated with platelet CD36 levels, however none have been conclusively demonstrated to be causative. We screened 81 expression quantitative trait loci (eQTL) single nucleotide polymorphisms (SNPs) associated with platelet CD36 expression …

Symmetrical Peripheral Gangrene Associated With Low Output Cardiac Failure., Sijan Basnet, Priya Rajagopalan, Rashmi Dhital, Ataul Qureshi

Reading Hospital Internal Medicine Residency

Symmetrical peripheral gangrene (SPG) is a rare entity characterized by ischemic changes of the distal extremities with maintained vascular integrity. We present the case of a 64-year-old man with bilateral necrotic toes and deranged liver function tests. This was thought to be related to severely depressed ejection fraction from non-ischemic etiology, presumably chronic alcohol ingestion. We hope that awareness of SPG and association with a low output state will aid in early detection and prevention.
