[Since it’s been over two and a half years since this UC Davis study was published and triclosan is still widely used, I am republishing this post from 8/21/2012.]
Due to an obsession with germs by Americans, antibacterial products have flooded the marketplace. Triclosan, introduced in the 1970’s, has become a popular antibacterial agent in consumer products.
Studies have raised the possibility that the overuse of triclosan contributes to making bacteria resistant to antibiotics, but new studies now attribute it to weakening cardiac and skeletal muscle contractility — a problem that can affect people with heart disease and heart failure.
Technology is helping doctors take a 3-D look at the hearts of possible heart attack victims. High-tech cardiac scans can provide three-dimensional images of the heart’s anatomy and blood circulation. It’s a non-invasive test and can detect if the heart’s blood vessels are blocked or narrowed.
The scan, the 64-slice CT scanner, is a huge advancement in cardiology and uses a combination of X-ray and computer technology. The life-saving machine produces cross-sectional images, often called “slices”, of the heart. The 64-slice scanner can spot things that couldn’t be seen on older scanners, such as the narrowing of arteries that cause heart attacks.
Low levels of radiation are used to create the image, so there is a risk of radiation exposure which may lead to cancer.
