Department of Medicine

Background: The popularity of e-cigarettes has risen dramatically over the last few years, particularly among the younger population. Although the use of combustible cigarettes has established evidence to be associated with the development of several adverse cardiopulmonary diseases, the investigations regarding the prospective long-term effects of e-cigarette use on the cardiovascular system have just begun. We set to investigate if there is an association between the history of MI and e-cigarette use among smokers and non-smokers?
Methods: The current review aims to assess the association of myocardial infarction with e-cigarette consumption. PubMed, Google Scholar, and Cochrane Central Register of Controlled …

Contrast-Enhanced Cardiac Magnetic Resonance Imaging With A Manganese-Based Alternative To Gadolinium For Tissue Characterization Of Acute Myocardial Infarction, Benjamin P. Bonner, Salva R. Yurista, Jaume Coll-Font, Shi Chen, Robert A. Eder, Anna N. Foster, Khoi D. Nguyen, Peter Caravan, Eric M. Gale, Christopher Nguyen

School of Medicine Faculty Publications

BACKGROUND: Late gadolinium enhancement cardiac magnetic resonance imaging is an effective and reproducible method for characterizing myocardial infarction. However, gadolinium-based contrast agents are contraindicated in patients with acute and chronic renal insufficiency. In addition, several recent studies have noted tissue deposition of free gadolinium in patients who have undergone serial contrast-enhanced magnetic resonance imaging. There is a clinical need for alternative forms of magnetic resonance imaging contrast agents that are acceptable in the setting of renal insufficiency. METHODS AND RESULTS: Three days after 80 minutes of ischemia/reperfusion of the left anterior descending coronary artery, cardiac magnetic resonance imaging was performed …

The Cardiovascular Manifestations Of Covid-19: A Review Of The Literature And Institutional Experience, Gina Polsinelli, Steven J. Korzeniewski, Oksana M. Doubrovski, James Paxton

Medical Student Research Symposium

The cardiovascular health of those infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) plays a major role in rates of hospitalization, mortality risk, and rates of mechanical ventilation. In patients with COVID-19, acute myocardial injury and history of cardiovascular disease are both independently established risk factors for poor patient prognosis. In addition to myocardial injury, numerous acute cardiovascular manifestations of COVID-19 disease have been identified. Previous work on this topic typically focused either upon a general description of the acute cardiovascular manifestations and sequalae of COVID-19, or upon broad-based clinical outcomes associated with COVID-19 in patients with history of …

An ST-segment myocardial infarction (STEMI) occurs when the blood flow to the myocardium is suddenly and completely blocked causing the myocardium to become ischemic. A STEMI is a life-threatening condition that necessitates emergent medical treatment. Research has shown that longer …

Atypical Presentation Of Stemi With Cardiac Tamponade Related To Malignancy, Matthew J. Johnson, Rohan Penmetcha

Rowan-Virtua Research Day

Cardiac tamponade and myocardial infarction are rare as the initial presentation of a malignancy. Here, we describe a case with an atypical presentation of a myocardial infarction due to a thrombus in the right coronary artery occurring in the setting of a pericardial effusion causing tamponade physiology related to malignancy. We present this unique case of myocardial infarction and cardiac tamponade as this was not caused by a type-A aortic dissection. In conclusion, we suggest that malignancy be considered in the differential diagnosis when these findings present together.

A Study Of Acoustically Activated Nanodroplets, Songita Choudhury

Theses & Dissertations

Current treatment of acute myocardial infarction (AMI), which is the main pathophysiological event leading to death in the United States, has advanced considerably with the introduction of emergent percutaneous interventions, but there remains an urgent need for novel techniques to rapidly and accurately detect infarcted or ischemic tissue that results from AMI. Ultrasound contrast agents, also known as microbubbles (MB), have become commonplace in echocardiography. However, MBs are purely intravascular tracers and unable to cross endothelial barriers due to size. The limitations of MBs, namely size and short circulation times within the human body, led to the development of phase-change …

Temporal Trends In Care And Outcomes Of Patients Receiving Fibrinolytic Therapy Compared To Primary Percutaneous Coronary Intervention: Insights From The Get With The Guidelines Coronary Artery Disease (Gwtg-Cad) Registry, Ravi S. Hira, Deepak L. Bhatt, Gregg C. Fonarow, Paul A. Heidenreich, Christine Ju, Salim S. Virani, Biykem Bozkurt, Laura A. Petersen, Adrian F. Hernandez, Lee H. Schwamm

Office of the Provost

Background: Timely reperfusion after ST-elevation myocardial infarction (STEMI) improves survival. Guidelines recommend primary percutaneous coronary intervention (PPCI) within 90 minutes of arrival at a PCI-capable hospital. The alternative is fibrinolysis within 30 minutes for those in those for whom timely transfer to a PCI-capable hospital is not feasible.
Methods and Results: We identified STEMI patients receiving reperfusion therapy at 229 hospitals participating in the Get With the Guidelines-Coronary Artery Disease (GWTG-CAD) database (January 1, 2003 through December 31, 2008). Temporal trends in the use of fibrinolysis and PPCI, its timeliness, and in-hospital mortality outcomes were assessed. We also assessed predictors …

BACKGROUND: Despite the increasing magnitude and impact, there are limited data available on the clinical management and in-hospital outcomes of patients who have diabetes mellitus (DM) and chronic kidney disease (CKD) at the time of hospitalization for acute myocardial infarction (AMI). The objectives of our population-based observational study in residents of central Massachusetts were to describe decade-long trends (1999-2009) in the characteristics, in-hospital management, and hospital outcomes of AMI patients with and without these comorbidities.

METHODS: We reviewed the medical records of 6,018 persons who were hospitalized for AMI on a biennial basis between 1999 and 2009 at all eleven …

Association Between Body Surface Area And Outcomes After Percutaneous Coronary Intervention, Kambiz Shetabi, Tonga Nfor, Fengyi Shen, Anjan Gupta, Tanvir Bajwa, Suhail Allaqaband

Journal of Patient-Centered Research and Reviews

Purpose

Obesity is a well-known risk factor for adverse cardiovascular events, but some studies suggest higher body mass index (BMI) is associated with better outcomes after ST-segment elevation myocardial infarction (STEMI). We sought to determine the effect of body surface area (BSA) on adverse events after primary percutaneous coronary intervention (PCI) for STEMI and how this relates to the reported obesity paradox theory.

Methods

We analyzed a prospective registry of patients with STEMI who underwent primary PCI at a tertiary care hospital from 2003 to 2009. Post-PCI complications and 1-year all-cause mortality were compared across BSA quartiles. Relationship with 1-year …

Redefining Myocardial Infarction: What Is New In The Esc/Accf/Aha/Whf Third Universal Definition Of Myocardial Infarction, Hani Jneid, Mahboob Alam, Salim S. Virani, Biykem Bozkurt

Office of the Provost

Myocardial infarction (MI) is a major cause of mortality and morbidity worldwide. Each year, an estimated 785,000 persons will have a new MI in the United States alone, and approximately every minute an American will succumb to one.1 In addition, MI has major psychological and legal implications for patients and the society and is an important outcome measure in research studies. The prevalence of MI provides useful data regarding the burden of coronary artery disease and offers insight into health care planning, policy, and resource allocation. The importance of accurately and reproducibly defining MI is therefore self-evident. The Third Universal …

Loss Of Dystrophin Staining In Cardiomyocytes: A Novel Method For Detection Early Myocardial Infarction, Satwat Hashmi, Suhail Al-Salam

Department of Biological & Biomedical Sciences

Myocardial infarction (MI) is the most frequent diagnosis made in majority of sudden death cases subjected to clinical and medicolegal autopsies. When sudden death occurs at a very early stage of MI, traditional macroscopic examination, or histological stains cannot easily detect the myocardial changes. For this reason we propose a new method for detecting MI at an early stage. Murine model of MI was used to induce MI through permanent ligation of left anterior descending branch of left coronary artery. Five groups of C57B6/J mice were used for inducing MI, which includes 20 minutes, 30 minutes, one hour, four hours …
