The Cardiovascular Center of Excellence, along with the Department of Pharmacology and Experimental Therapeutics, led an all LSU Health New Orleans original investigation into understanding, "Renal Sympathetic Denervation Protects the Failing Heart Via Inhibition of Neprilysin Activity in the Kidney." The investigation was led by CV Center members David Polhemus, Ph.D., Rishi Trivedi, Ph.D., Zhen Li and Amy Scarborough.
The study had a clear objective that 'investigated the effects of radiofrequency renal nerve denervation (RF-RDN) on the pathobiology of HF and the interaction between the renal sympathetic nerves and natriuretic peptide (NP) metabolism.'
The LSUHSC Center of Excellence in Cardiovascular Research hosts an exciting Cardiovascular Biology Seminar Series! Renowned scientists from prestigious and innovative institutions visit our Center regularly, sharing ideas and inspiring us to become the best. Please take a moment to view the LSU Health Science Center Medical School – Seminar Calendar. These seminars are golden opportunities to learn and visit with other scientists who aspire with similar interests.

$1.3 Million Grant to Fund Research on Reducing Cardiac Injury
with the First Drug-Eluting Guidewire
New Orleans, LA (August 11, 2017) – Adenopaint, LLC of Atlanta, GA, in conjunction with LSU Health New Orleans Cardiovascular Center of Excellence, has been awarded an SBIR Phase II grant in the amount of $1.3 million over two years by the National Heart, Lung and Blood Institute.
The funding will be used to study the company’s Adenowire, a novel guidewire coated with a drug which is released during percutaneous coronary intervention (PCI) to prevent and reverse vascular and cardiac tissue injury during PCI and therefore improve outcomes in cardiovascular diseases.

Cardiovascular Center Welcomes, Thomas E. Sharp III, Ph.D.
Dr. Thomas E. Sharp III joined the Cardiovascular Center of Excellence in July as a Postdoctoral Researcher. Dr. Sharp joins us from Temple University, Lewis Katz School of Medicine where he recieved his Ph.D. while working under reknowned professor, John Elrod, Ph.D.. He will work alongside both Dr. Lefer and Dr. Goodchild to continue ongoing research.
Is Cardioprotection Dead?
David J. Lefer, Ph.D., along with Eduardo Marban, M.D., Ph.D., co-authored the latest abstract titled, 'Is Cardioprotection Dead?', issued by the American Heart Association's Circulation as part of their July 2017 issue.
Acknowledgments were also given to CV Students David J. Polhemus, Ph.D. and Rishi Trivedi, Ph.D. for their laboratory research.
The Abstract Summary
"For >4 decades, the holy grail in the treatment of acute myocardial infarction has been the mitigation of lethal injury. Despite promising initial results and decades of investigation by the cardiology research community, the only treatment with proven efficacy is early reperfusion of the occluded coronary artery. The remarkable record of failure has led us and others to wonder if cardioprotection is dead. The path to translation, like the ascent to Everest, is certainly littered with corpses. We do, however, highlight a therapeutic principle that provides a glimmer of hope: cellular postconditioning. Administration of cardiosphere-derived cells after reperfusion limits infarct size measured acutely, while providing long-term structural and functional benefits. The recognition that cell therapy may be cardioprotective, and not just regenerative, merits further exploration before we abandon the pursuit entirely."

Dr. Wu Shares Insight on iPSCs for Cardiovascular Precision Medicine
Dr. Joseph C. Wu, Professor of Medicine and Radiology; Director of Stanford Cardiovascular Institute; Simon H. Stertzer Endowed Professorship from Stanford University School of Medicine presented the seminar on Induced pluripotent stem cells in cardiology, ‘iPSCs for Cardiovascular Precision Medicine’.
His presentation served as the 5th installment of the Cardiovascular Center of Excellence 2017 Seminar Series. During his visit in New Orleans, Dr. Wu met with LSUHSC professors and postdocs to discuss ongoing projects and potential collaborations.
His seminar covered a wide-range of topics discussing iPSC usage such as organ structure and function, patient phenotype, DNA sequence, gene expression and more. To learn more about Dr. Wu’s research, visit Nature Reviews – Cardiology.

Cardiovascular Center Faculty Published in Angewandte Chemie International
The combined research efforts by the Cardiovascular Center faculty contributed to the manuscript, ‘A Novel Esterase-sensitive Prodrug Approach for Controllable Delivery of Persulfide Species’, being accepted in the Angewandte Chemie International 2017 Edition.
Center faculty David J. Lefer, PhD; Chelsea L. Organ, PhD; Rishi K. Trivedi, PhD; and Zhen Li all made contributions to the study. The manuscript was peer-reviewed and accepted on July 12, 2017.
The Abstract Summary
“A new strategy to deliver a well-defined persulfide species in a biological medium is described herein. Under near physiological conditions, the persulfide prodrug can be activated by an esterase to generate a "hydroxyl methyl persulfide" intermediate, which rapidly collapses to form a defined persulfide. Such persulfide prodrugs can be used either as chemical tools to study persulfide chemistry and biology or for future development as H2S-based therapeutic reagents. Using the persulfide prodrugs developed in this study, the reactivity between S-methyl methanethiosulfonate (MMTS) with persulfide was unambiguously demonstrated. In addition, a representative prodrug exhibited potent cardioprotective effects in a murine model of myocardial ischemia-reperfusion (MI/R) injury with a bell shape therapeutic profile.”
