Examining Symptom Trajectories That Predict Worse Outcomes In Post-Cabg Patients, Ming-Fen Tsai, Shiow-Luan Tsay, Debra K. Moser, Tsuey-Yuan Huang, Feng-Chun Tsai

Nursing Faculty Publications

Background: Coronary artery bypass grafting is one of the most common interventional revascularisation procedures used to treat coronary artery disease worldwide. With a wide variability in postoperative cardiac symptoms, identification of symptom trajectories during the 3-month postoperative recovery period may improve clinicians’ abilities to support symptom recovery.

Aims: To identify distinct trajectories of cardiac symptoms seen over time in a cohort of patients during the 3-month post-coronary artery bypass grafting period, and determine clinical characteristics associated with different symptom trajectories postoperatively.

Methods: A prospective trial used the cardiac symptom survey to determine patient symptoms at baseline prior to surgery, and …

Nursing Faculty Publications

Background: Patients with heart failure (HF) can suffer from increased thirst intensity and distress. Trajectories of thirst intensity and distress from hospital to home are unclear. The aim of this study was to describe thirst intensity and distress trajectories in patients from the time of hospital admission to 4 weeks after discharge, and describe trajectories of thirst intensity and distress by patients’ characteristics (gender, age, body mass index [BMI], plasma urea, anxiety, and depression).

Patients and methods: In this observational study, data were collected from patients with HF (n=30) at hospital admission, discharge, and at 2 and 4 weeks after …

New Oral Anticoagulants And Their Reversal Agents, Crista L. Laslo, Anca Pantea Stoian, Bogdan Socea, Dan N. Paduraru, Oana Bodean, Laura I. Socea, Tiberiu P. Neagu, Ana Maria Alexandra Stanescu, Dragos Marcu, Camelia C. Diaconu

Journal of Mind and Medical Sciences

Atrial fibrillation is a commonly encountered pathology in medical practice, and its prevalence has shown a continuous rise over the past years. Atrial fibrillation has a significant impact on patients' quality of life, not only due to the standard anticoagulant treatment with vitamin K antagonists that require close monitoring and dose adjustment, but also due to the fragile equilibrium between hemorrhagic and thrombotic risks. The introduction of new oral anticoagulants (NOACs) in the treatment guidelines for atrial fibrillation has improved the quality of life, as NOACs do not require close monitoring or dose adjustments. However, even if the safety profile …

A Curious Case Of Intermittent Left Bundle Branch Block Associated With Cough, Hunaina Shahab, Osman Faheem, Kumail Khandwala, Aamir Hameed

Section of Cardiology

A handful of cases of voluntary control of left bundle branch block (LBBB) have been described in the literature. We report the case of a middle-aged man who was found to have LBBB on baseline electrocardiogram (ECG) which disappeared on coughing and then reappeared with the same maneuver. Subsequent myocardial perfusion scan showed reduced count in the anteroseptal region likely attributed to LBBB. It is possible that the intermittent conduction changes may be due to the alteration in the vagal tone associated with cough as reflected in the change in the PR interval on the ECG.

Sleep Fainting: A Neurocardiogenic Entity, Hunaina Shahab, Ambreen A. Sonawalla, Maryam Khan, Aman Qureshi

Section of Cardiology

Fainting is a common clinical presentation, with vagally mediated (neurocardiogenic) causes being the most common for syncope presentation to the emergency room, and for hospital admissions. Classic teaching is that upright posture is a prerequisite for vagally mediated syncope (VMS) and that syncope in the supine position has more sinister causes. We present five patients, three males and two females, with a mean age of 44.4 (range 29-67) years, who presented with VMS in the supine position (sleep fainting). Four patients also had a history of classic upright syncope. Based on their clinical features and thorough investigations, we excluded other …

Gill Heart & Vascular Institute Faculty Publications

BACKGROUND

Despite the high rate of sudden death after myocardial infarction among patients with a low ejection fraction, implantable cardioverter–defibrillators are contraindicated until 40 to 90 days after myocardial infarction. Whether a wearable cardioverter–defibrillator would reduce the incidence of sudden death during this high-risk period is unclear.

METHODS

We randomly assigned (in a 2:1 ratio) patients with acute myocardial infarction and an ejection fraction of 35% or less to receive a wearable cardioverter–defibrillator plus guideline-directed therapy (the device group) or to receive only guideline-directed therapy (the control group). The primary outcome was the composite of sudden death or death from …

Takotsubo Cardiomyopathy Associated With Polycythemia Vera., Sijan Basnet, Priya Rajagopalan, Rashmi Dhital, Biswaraj Tharu

Reading Hospital Internal Medicine Residency

Takotsubo cardiomyopathy is characterized by transient apical ballooning with preserved basal ventricular function triggered by physical or emotional stressors. We present a case of a 75-year-old man referred to our facility for the management of acute myocardial infarction later diagnosed as takotsubo cardiomyopathy. We believe platelet-mediated adrenaline release from massive thrombocytosis might have been the precipitating factor for the pathogenesis of takotsubo cardiomyopathy.

Comparison Of Left Ventricular Strains And Torsion Derived From Feature Tracking And Dense Cmr, Gregory J. Wehner, Linyuan Jing, Christopher M. Haggerty, Jonathan D. Suever, Jing Chen, Sean M. Hamlet, Jared A. Feindt, Walter Dimitri Mojsejenko, Mark A. Fogel, Brandon K. Fornwalt

Biomedical Engineering Faculty Publications

Background: Cardiovascular magnetic resonance (CMR) feature tracking is increasingly used to quantify cardiac mechanics from cine CMR imaging, although validation against reference standard techniques has been limited. Furthermore, studies have suggested that commonly-derived metrics, such as peak global strain (reported in 63% of feature tracking studies), can be quantified using contours from just two frames – end-diastole (ED) and end-systole (ES) – without requiring tracking software. We hypothesized that mechanics derived from feature tracking would not agree with those derived from a reference standard (displacement-encoding with stimulated echoes (DENSE) imaging), and that peak strain from feature tracking would agree with …

Effects Of Beta Blockers And Ace Inhibitors After Left Ventricular Assist Device Implantation, Gaurang Vaidya, Emma Birks, Jessica Pillarella, Benjamin Salgado, Rajakrishnan Vijayakrishnan, Andrew Lenneman, Mark Slaughter, Dmitry Abramov

The VAD Journal

Purpose: While Beta blockers(BB) and Angiotensin system blockers(ACEinh/ARB) are important components in advanced heart failure therapy, their use after left ventricular assist device (LVAD) implantation remains controversial. Concern has been raised about possible adverse effects of BB on right ventricular(RV) function while tolerance and efficacy/outcome data for ACEinh are lacking. This study aimed to characterize the use of medical therapy post-LVAD implantation and to evaluate its safety and efficacy. Methods: Demographic, clinical and echocardiographic variables of patients implanted with a continuous-flow LVAD between 2012 and 2015 at a single center were retrospectively reviewed. Mortality and heart failure(CHF) hospitalizations were followed …

Transcriptional Up-Regulation Of Relaxin-3 By Nur77 Attenuates Β-Adrenergic Agonist-Induced Apoptosis In Cardiomyocytes., Xiaohua You, Zhifu Guo, Fang Cheng, Bing Yi, Fan Yang, Xinzhu Liu, Ni Zhu, Xianxian Zhao, Guijun Yan, Xin-Liang Ma, Jianxin Sun

Center for Translational Medicine Faculty Papers

The relaxin family peptides have been shown to exert several beneficial effects on the heart, including anti-apoptosis, anti-fibrosis, and anti-hypertrophy activity. Understanding their regulation might provide new opportunities for therapeutic interventions, but the molecular mechanism(s) coordinating relaxin expression in the heart remain largely obscured. Previous work demonstrated a role for the orphan nuclear receptor Nur77 in regulating cardiomyocyte apoptosis. We therefore investigated Nur77 in the hopes of identifying novel relaxin regulators. Quantitative real-time PCR (qRT-PCR) and enzyme-linked immunosorbent assay (ELISA) data indicated that ectopic expression of orphan nuclear receptor Nur77 markedly increased the expression of latexin-3 (RLN3), but not relaxin-1 …

Student Papers, Posters & Projects

Objective: Rare disease Background: Antiphospholipid syndrome (APS) is an autoimmune disease characterized by antibodies directed against phos-pholipids on plasma membranes. Through unclear mechanisms, APS confers hypercoagulability. APS may cause recurrent thromboses in the arterial and venous vasculature. We report a case of primary APS resulting in cerebral venous thrombosis and ST-elevation myocardial infarction (STEMI) for which only antiphosphatidylserine (aPS) IgM antibody was positive after extensive investigation. Case Report: A 48-year-old male was admitted after a witnessed generalized seizure with subsequent confusion. Imaging demonstrated thrombosis of multiple central nervous system (CNS) sinuses, including the superior sagittal sinus and bilateral transverse sinuses. …

Bevacizumab: A Rare Cause Of Nonischemic Cardiomyopathy., Oreoluwa Oladiran, Salik Nazir

Reading Hospital Internal Medicine Residency

Left ventricular dysfunction is a rare side effect of bevacizumab occurring in 2-4% of cases. We report the case of a 68-year-old woman who presented to the emergency department (ED) with sudden onset of shortness of breath, orthopnea, and paroxysmal nocturnal dyspnea. She was tachypneic and in respiratory distress. Physical examination revealed jugular venous distention, diffuse expiratory wheeze, and bipedal edema. She had been started on bevacizumab for the treatment of hereditary hemorrhagic telangiectasia 1 month prior to presentation. Laboratory tests revealed BNP of 1697 pg/ml with slightly elevated troponin 0.05 ng/ml. Chest X-ray showed interstitial edema with cardiomegaly, and …

Overcoming Small Data Limitations In Heart Disease Prediction By Using Surrogate Data, Alfeo Sabay, Laurie Harris, Vivek Bejugama, Karen Jaceldo-Siegl

SMU Data Science Review

In this paper, we present a heart disease prediction use case showing how synthetic data can be used to address privacy concerns and overcome constraints inherent in small medical research data sets. While advanced machine learning algorithms, such as neural networks models, can be implemented to improve prediction accuracy, these require very large data sets which are often not available in medical or clinical research. We examine the use of surrogate data sets comprised of synthetic observations for modeling heart disease prediction. We generate surrogate data, based on the characteristics of original observations, and compare prediction accuracy results achieved from …

MaineHealth Maine Medical Center

Problem/Impact Statement:

85% of first cases at Maine Medical Center for Vascular Surgery start late. According to one study done by Aurora Health Care; of 5,500 first case surgeries, 88% of them started late. The impact of this is far reaching. It is not in alignment with MMC value of Patient Centered Care because the patient becomes dissatisfied waiting to be brought in to surgery , they are fasting for longer than anticipated, and being away from their family while they wait causing anxiety. The financial impact is $1995 for each 1⁄2 hr. of O.R. time. Furthermore, this may result …

Electrocardiographic Characteristics, Antiarrhythmic Utilization, And Outcomes In Patients With Left Ventricular Assist Devices, Scott Lundgren, Elizabeth Lyden, Douglas Stoller, Marshall Hyden, Adam Burdorf, Ronald Zolty, John Um, Brian Lowes

The VAD Journal

Background: Left ventricular assist devices (LVAD) are an increasingly used therapy for patients with advanced heart failure. Arrhythmias are common complications following LVAD implantation requiring admission, initiation, and escalation of medical therapy. Despite their frequent use in the treatment of arrhythmias, little has been reported regarding electrocardiographic changes, antiarrhythmic utilization, and outcomes post-LVAD.

Methods: A total of 309 patients who received a LVAD underwent retrospective chart review pre- and post-LVAD. Kaplan-Meier curves were calculated and compared using the log-rank test. Cox regression model was used for univariate analysis and those with a p

Results: There was a significant reduction in …

A Rare Case Of Spontaneous Cardiac Tamponade Induced By Concomitant Use Of Rivaroxaban And Amiodarone., Oreoluwa Oladiran, Jared Segal, Ifeanyi Nwosu, Salik Nazir

Reading Hospital Internal Medicine Residency

Rivaroxaban is a direct oral anticoagulant (DOAC) approved as an important alternative to warfarin in patients with nonvalvular atrial fibrillation. We report the case of an 87-year-old man with past medical history of nonvalvular atrial fibrillation on rivaroxaban and recently started amiodarone for pulseless ventricular tachycardia who presented to our hospital with intermittent chest pain and was diagnosed with spontaneous hemopericardium causing cardiac tamponade. The culprit drugs were discontinued, and the patient was treated with emergent pericardiocentesis. Both rivaroxaban and amiodarone are substrates for the CYP3A4 hepatic pathway, and concomitant use can result in increased plasma rivaroxaban levels causing an …

Abington Jefferson Health Papers

Left ventricular pseudoaneurysm is a rare but life-threatening disorder that is frequently reported secondary to myocardial infarction or cardiac surgery. In this article, we chronicle the case of a patient with no prior risk factors who presented with a 2-week history of nonexertional atypical left chest pain. Apical 2-chamber transthoracic echocardiography revealed an unexpected outpouching of basal inferoseptal wall of the left ventricle, which had a narrow neck and relatively wide apex. The patient was diagnosed with left ventricular pseudoaneurysm and medical therapy was initiated. He refused to undergo the surgical intervention and subsequently, he was discharged from the hospital …
