Hailed as miracle drugs when they hit the market two decades ago, statins, the cholesterol-lowering drugs prescribed to prevent heart attacks, are not as effective nor as safe as we have been led to believe, say Dr. David M. Diamond, a professor of psychology, molecular pharmacology and physiology at the University of South Florida, and Dr. Uffe Ravnskov, an independent health researcher and an expert in cholesterol and cardiovascular disease.
According to Diamond and Ravnskov, statins produce a dramatic reduction in cholesterol levels, but they have "failed to substantially improve cardiovascular outcomes." They further state that the many studies touting the efficacy of statins have not only neglected to account for the numerous serious adverse side effects of the drugs, but supporters of statins have used what the authors refer to as "statistical deception" to make inflated claims about their effectiveness.
Their critique of the exaggerated claims regarding statins' ability to prevent strokes, heart attacks and heart disease-related deaths on a large scale has been published in the medical journal "Expert Review of Clinical Pharmacology".
Their paper is an analysis of the data in the statin trials which led them to conclude that "statin advocates have used statistical deception to create the illusion that statins are 'wonder drugs,' when the reality is that their modest benefits are more than offset by their adverse effects."
The paper also describes how the basis of the deception is in how authors of the statin studies present the rate of beneficial and adverse effects. The effect of the drugs on the population is called the 'absolute risk,' which has shown that statins benefit only about 1% of the population. This means that only one out of 100 people treated with a statin will have one less heart attack. Statin researchers, however, don't present the 1% effect to the public. Instead they transform the 1% effect using another statistic, called the "relative risk," which creates the appearance that statins benefit 30-50% of the population.
The exaggeration of beneficial effects of statin treatment was illustrated in their analysis of a subset of statin studies, including the Jupiter Trial (Crestor), the Anglo-Scandinavian Cardiac Outcomes Trial Lipid Lowering Arm (ASCOT-LLA), and the British Heart Protection Study.
