Statin Drugs are thought to reduce risk for heart attacks and stroke. However, there is no scientific evidence that these drugs are useful at all. Drug companies use their influence to lower the blood pressure level recommendation in order to haul in more patients to buy statin drugs. Many of the people who take these drugs do not even need to be on them. Make sure to ask your physician ahead of time about the uses of certain drugs. Try to prevent heart attacks and strokes through lifestyle and diet rather than by taking drugs.
