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 …

Left Ventricular Pseudoaneurysm: An Overview Of Diagnosis And Management., Faisal Inayat, Ali Raza Ghani, Iqra Riaz, Nouman Safdar Ali, Usman Sarwar, Raphael Bonita, Hafeez Ul Hassan Virk

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 …

Myocardial Dysfunction After Out-Of-Hospital Cardiac Arrest: Predictors And Prognostic Implications., Yuan Yao, Nicholas James Johnson, Sarah Muirhead Perman, Vimal Ramjee, Anne Victoria Grossestreuer, David Foster Gaieski

Department of Emergency Medicine Faculty Papers

We aim to determine the incidence of early myocardial dysfunction after out-of-hospital cardiac arrest, risk factors associated with its development, and association with outcome. A retrospective chart review was performed among consecutive out-of-hospital cardiac arrest (OHCA) patients who underwent echocardiography within 24 h of return of spontaneous circulation at three urban teaching hospitals. Our primary outcome is early myocardial dysfunction, defined as a left ventricular ejection fraction < 40% on initial echocardiogram. We also determine risk factors associated with myocardial dysfunction using multivariate analysis, and examine its association with survival and neurologic outcome. A total of 190 patients achieved ROSC and underwent echocardiography within 24 h. Of these, 83 (44%) patients had myocardial dysfunction. A total of 37 (45%) patients with myocardial dysfunction survived to discharge, 39% with intact neurologic status. History of congestive heart failure (OR 6.21; 95% CI 2.54-15.19), male gender (OR 2.27; 95% CI 1.08-4.78), witnessed arrest (OR 4.20; 95% CI 1.78-9.93), more than three doses of epinephrine (OR 6.10; 95% CI 1.12-33.14), more than four defibrillations (OR 4.7; 95% CI 1.35-16.43), longer duration of resuscitation (OR 1.06; 95% CI 1.01-1.10), and therapeutic hypothermia (OR 3.93; 95% CI 1.32-11.75) were associated with myocardial dysfunction. Cardiopulmonary resuscitation immediately initiated by healthcare personnel was associated with lower odds of myocardial dysfunction (OR 0.40; 95% CI 0.17-0.97). There was no association between early myocardial dysfunction and mortality or neurological outcome. Nearly half of OHCA patients have myocardial dysfunction. A number of clinical factors are associated with myocardial dysfunction, and may aid providers in anticipating which patients need early diagnostic evaluation and specific treatments. Early myocardial dysfunction is not associated with neurologically intact survival.

Department of Emergency Medicine Faculty Papers

Cardiokines play an essential role in maintaining normal cardiac functions and responding to acute myocardial injury. Studies have demonstrated the heart itself is a significant source of C1q/TNF-related protein 9 (CTRP9). However, the biological role of cardiac-derived CTRP9 remains unclear. We hypothesize cardiac-derived CTRP9 responds to acute myocardial ischemia/reperfusion (MI/R) injury as a cardiokine. We explored the role of cardiac-derived CTRP9 in MI/R injury via genetic manipulation and a CTRP9-knockout (CTRP9-KO) animal model. Inhibition of cardiac CTRP9 exacerbated, whereas its overexpression ameliorated, left ventricular dysfunction and myocardial apoptosis. Endothelial CTRP9 expression was unchanged while cardiomyocyte CTRP9 levels decreased after simulated …

Validation Of An Icd Code For Accurately Identifying Emergency Department Patients Who Suffer An Out-Of-Hospital Cardiac Arrest., Shelby K. Shelton, Steve B. Chukwulebe, David F. Gaieski, Benjamin S. Abella, Brendan G. Carr, Sarah M. Perman

Department of Emergency Medicine Faculty Papers

AIM: International classification of disease (ICD-9) code 427.5 (cardiac arrest) is utilized to identify cohorts of patients who suffer out-of-hospital cardiac arrest (OHCA), though the use of ICD codes for this purpose has never been formally validated. We sought to validate the utility of ICD-9 code 427.5 by identifying patients admitted from the emergency department (ED) after OHCA.

METHODS: Adult visits to a single ED between January 2007 and July 2012 were retrospectively examined and a keyword search of the electronic medical record (EMR) was used to identify patients. Cardiac arrest was confirmed; and ICD-9 information and location of return …

Deciphering A Case Of Pulmonary Hypertension In A Young Female: Partial Anomalous Pulmonary Venous Drainage The Culprit, Hiten R. Patel, Suchit Bhutani, Fayez Shamoon, Hartaj Virk

Abington Jefferson Health Papers

Partial anomalous pulmonary venous drainage (PAPVD) is a rare congenital cardiac defect and is associated with sinus venosus atrial septal defect. While most cases are asymptomatic, a patient can present with pulmonary hypertension (PHTN) and it can be difficult to diagnose. Here, we discuss the case of a young female with PHTN who was found to have two right-sided PAPVD. Through this case, authors try to emphasize the importance of meticulous and thorough investigation when evaluating PHTN, which allows for correct diagnosis and a timely intervention before PHTN becomes irreversible.

Hmgcs2 Is A Key Ketogenic Enzyme Potentially Involved In Type 1 Diabetes With High Cardiovascular Risk., Sanket Kumar Shukla, Weijing Liu, Kunal Sikder, Sankar Addya, Amrita Sarkar, Yidong Wei, Khadija Rafiq

Center for Translational Medicine Faculty Papers

Diabetes increases the risk of Cardio-vascular disease (CVD). CVD is more prevalent in type 2 diabetes (T2D) than type 1 diabetes (T1D), but the mortality risk is higher in T1D than in T2D. The pathophysiology of CVD in T1D is poorly defined. To learn more about biological pathways that are potentially involved in T1D with cardiac dysfunction, we sought to identify differentially expressed genes in the T1D heart. Our study used T1D mice with severe hyperglycemia along with significant deficits in echocardiographic measurements. Microarray analysis of heart tissue RNA revealed that the T1D mice differentially expressed 10 genes compared to …
