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: Engineering Around Extreme Events
Extreme events, such as super floods and hurricanes, are becoming more common, so civil engineers are trying to adapt civil infrastructure such as bridges to these unpredictable and sometimes devastating meteorological events. Engineer Ana Barros discusses how engineering can prepare us for extreme weather events, but also how changing climate and population conditions can affect the ability of infrastructure to hold up over time.
