More Appropriate Use of Cardiac Stress Testing With Imaging Could Reduce Health Costs, Improve Patient Outcomes

In a new study recently published  in the Annals of Internal Medicine, researchers at NYU Langone Medical Center concluded that overuse of  cardiac stress testing with imaging has led to  rising healthcare costs and unnecessary radiation exposure to patients. Lead author, Joseph Ladapo, MD, PhD, assistant professor in the Departments of Medicine and Population Health, and colleagues wanted to determine whether U.S. trends in cardiac stress testing with imaging may be attributable to population shifts in demographics, risk factors, and provider characteristics, and to evaluate whether racial/ethnic disparities exist in physician decision making.

Novel Protein in Heart Muscle Linked to Cardiac Short-Circuiting, Ventricular Arrhythmias and Sudden Cardiac Deaths

Cardiovascular scientists at NYULMC have identified in mouse models a protein known as Pcp4 as a regulator of the heart’s rhythm. Additionally, when the Pcp4 gene is disrupted, it can cause ventricular arrhythmias. Led by Glenn I. Fishman, MD, William Goldring Professor of Medicine and Director of the Leon H. Charney Division of Cardiology at NYU Langone, results from this study were released online in the peer-reviewed publication, The Journal of Clinical Investigation. Read more...
