Yoram Rudy retires (Links to an external site)

For biomedical engineer Yoram Rudy, a new chapter awaits

It’s no wonder that after such a long, accomplished and productive career, Yoram Rudy is not quite ready to retire from his life’s work. Yes, he stepped down at the end of 2022 from his role as director of the Cardiac Bioelectricity and Arrhythmia Center — which he founded in 2004 — to become emeritus professor, but he sees this next step as yet another opportunity to begin anew. With a life defined by an inquisitiveness that has furthered the field of biomedicine, Rudy has trained and inspired a new generation of bioengineers as they make their own discoveries in service to humanity.

Radiation therapy reprograms heart muscle cells to younger state (Links to an external site)

Stacey Rentschler Radiation therapy reprograms heart muscle cells to younger state

Radiotherapy repairs irregular rhythms in those with life-threatening heart arrhythmia.

New research from Washington University School of Medicine in St. Louis suggests that radiation therapy can reprogram heart muscle cells to what appears to be a younger state, fixing electrical problems that cause a life-threatening arrhythmia without the need for a long-used, invasive procedure.

Compound may prevent risk of a form of arrhythmia from common medications (Links to an external site)

Jianmin Cui, KCNQ1

CBAC Jianmin Cui leads a multi-institutional team to make this discovery. Dozens of commonly used drugs, including antibiotics, antinausea and anticancer medications, have a potential side effect of lengthening the electrical event that triggers contraction, creating an irregular heartbeat, or cardiac arrhythmia called acquired Long QT syndrome. While safe in their current dosages, some of these drugs may have a more therapeutic benefit at higher doses, but are limited by the risk of arrhythmia.

Engineers find unexpected results during cardiac research. This article features CBAC members Jonathan Silva, assistant professor of biomedical engineering, and Jeanne Nerbonne, Alumni Endowed Professor of Molecular Biology and Pharmacology and director of the Center for Cardiovascular Research at Washington University’s School of Medicine.

Silva, Nerbonne and Zoltan Varga from the University of Debrecen in Hungary worked with collaborators to take a closer look at the sodium ion channels responsible for creating the electrical signal that makes the heartbeat.They found that certain sodium subunits attached to the main protein in different places. It was an unexpected result that could lead to better drug delivery and efficacy for patients with heart arrhythmia.

CardioInsight ECVUE

While working a Case Western Reserve University, CBAC Director Yoram Rudy, PhD had the idea for a game-changing cardiac monitoring device–a vest filled with more than 200 sensors that could detect the heart’s electrical activity. While standard 12-lead EKGs had become the gold standard for detecting many heart problems, EKGs still can miss cardiac problems because they only probe electrical potential at a limited number of points on the body.
