VOAVideo: New Heart Stents Better Than Old Ones, Study Says
Stents are used to keep coronary arteries open after a procedure called angioplasty. Some stents contain medicine that is released over time. It was thought that these stents would be more effective than plain metal ones, but early studies showed patients who had medicated stents were more llikely to have a heart attack than patients who got plain stents. Now there's a new generation of stents that release medication and a new study about their performance. VOA's Carol Pearson reports.
