Statins -- controversial, miraculous, and ubiquitous -- are the world's best-selling drugs. We hope that this book will help people have better conversations about statins with their doctors. Because some leading medical groups have recently recommended giving statins to more people with low or moderate risk of heart and vascular problems (instead of only high-risk patients), tens of millions more people with no symptoms at all of any problem are being faced with the issue of whether or not to start the drugs. This book will help them bring more solid information to making that decision.
