New tool could prevent needless stents and save money, cardiologist says

"Doctors may be implanting too many artery-opening stents and could improve patient outcomes - and ultimately save lives - if they did more in-depth measurements of blood flow in the vessels to the heart. That's the finding of a study, to be published January 15 in the New England Journal of Medicine, that evaluated the benefits of a new diagnostic tool to measure blood flow and determine whether stenting was the best option." - PhysOrg.com
