Drugs Can Save Hearts and Cash
from the (Raleigh, N.C.) News and Observer
It's much cheaper and just as effective to treat some heart attacks with drugs instead of also trying to snake a stent into a clogged artery, scientists at Duke University report today in the New England Journal of Medicine.
The findings could prompt significant savings for many of the estimated 1.2 million Americans who suffer heart attacks each year. Wire mesh stents open clogged arteries and can save lives when used within a few hours of a heart attack, but they're no more beneficial than clot-busting drugs alone if the attack occurred a day or so before the patient sought treatment.
Forgoing stents in those cases could save an average of $7,000 per patient—or $700 million for the estimated 100,000 U.S. heart attack patients who don't need them.

PODCAST & VIDEO: 3D Printing Replacement Body Parts
Regenerative medicine, a fledgling field with the aim of regrowing parts from a person’s own cells, is being amplified with 3D-printing technology, which can now use organic materials to create scaffolds that cells need to grow into their final forms. Richard Wysk, a professor of industrial and systems engineering at North Carolina State University, discusses the latest successes with this research, and the timeline for creating more complicated structures.
