Imagine there was a drug that you could take soon after a heart attack that could reduce damage by protecting healthy heart muscle tissue.
Imagine there was a drug that you could take soon after a heart attack that could reduce damage by protecting healthy heart muscle tissue.
“Cardiologists say that when a heart attack occurs, time is muscle,” said Robert Gourdie, director of the Fralin Biomedical Research Institute at VTC Center for Heart and Reparative Medicine Research.
Without oxygen supplied by blood flow, heart cells die — fast. But while a heart attack may only reduce blood and oxygen to an isolated section of heart cells — causing what’s called hypoxic ischemic injury — those dying cells send signals to their neighbors.
“The problem is that the area of dying tissue is not quarantined. Damaged heart cells start to send out signals to otherwise healthy cells, and the injury becomes much bigger,” said Gourdie, who is also the Commonwealth Research Commercialization Fund Eminent Scholar in Heart Regenerative Medicine Research and a professor in the Department of Biomedical Engineering and Mechanics in the Virginia Tech College of Engineering.
