Beta blockers are busted
The 20 or so beta blockers now on the market are very widely used - almost 200 million prescriptions were written for them in the US in 2010. They are standard issue for most people with heart disease or high blood pressure. This may now change.A large study published last month in The Journal of the American Medical Association found that beta blockers did not prolong the lives of patients - a revelation that must have left many cardiologists shaking their heads (JAMA, vol 308, p 1340).The researchers followed almost 45,000 heart patients over three-and-a-half years and found that beta blockers did not reduce the risk of heart attacks, deaths from heart attacks, or stroke.While this is not definitive, it's pretty damning, especially when another study - published just days earlier - found pretty much the same thing (Journal of the American Geriatrics Society, vol 60, p 1854).
