American College of Cardiology annual meeting: Roundup
American College of Cardiology annual meeting,March 6–9, Orlando
Here is more news from the American College of Cardiology meeting:
Absorbable stents. German researchers reported using stents that disappear in a month or so to successfully open coronary arteries in five men. The inner wall of the artery gradually absorbs the stent, which is made almost entirely of magnesium. Disappearing stents would be useful in children, whose arteries continually grow. In adults, they would allow the stented section of artery to expand and contract naturally. Several types of absorbable plastic stents are also being tested.
Rimonabant rolls on. What do cannabinoids (the active ingredients in marijuana) and heart disease have in common? More than you think. The experimental drug rimonabant (Acomplia) belongs to a class of drugs aimed at blocking cannabinoid receptor 1. Results from a two-year trial called RIO–Europe show that the drug helped obese volunteers lose weight and shrink waist size. It also boosted HDL and reduced triglycerides. Earlier studies have shown that rimonabant can help smokers stop smoking. Despite these promising results, worries over drug safety sparked by Vioxx and Celebrex mean that rimonabant will probably remain under the clinical microscope for some time before its maker, Sanofi-Aventis, asks the FDA to approve it for use in the United States.
