5. Cholesterol-lowering may shorten your life
An excerpt from my previous book
The Cholesterol Myths (out of print).
Before the introduction of the new cholesterol lowering drugs, the statins, more than 40 trials have been performed to test if cholesterol-lowering can prevent a heart attack. In some of the trials the number of fatal heart attacks were lowered a little, in other trials the number of fatal heart attacks increased. Overviews of the trials have shown that when all results were taken together, just as many died in the treatment groups (e.g. those whose cholesterol was lowered) as in the untreated control group (78,79). The following table gives the accumulated results. None of the differences were statistically significant. Nor were they by more sophisticated analyses.
That some overviews have shown a positive result after cholesterol-lowering is because they had ignored or excluded one or more trials with a negative outcome (79).
The mentioned overviews included mostly diet and/or the older cholesterol-lowering drugs. But a new type of drugs, the socalled statins (for instance Zocord®, Mevacor®, Lescol®, Lipitor® and Pravachol®) have been succesful. However, their effect isn´t exerted through cholesterol-lowering, they have other and more useful properties Unfortunately they also stimulate cancer growth (see section 6)
