The purpose of this study is to determine whether supplements of Q10 and Selen are effective in reducing muscular adverse events (AE) in statin therapy.

Statins inhibit the synthesis of cholesterol by inhibiting the enzyme HMG-CoA reductase. The reduction of intracellular cholesterol leads to an increase in the number of LDL-receptors, and subsequent increased uptake and metabolism of LDL in the liver. Several large clinical trials have shown that the use of statins decreases morbidity and mortality in patients with risk factors for atherosclerotic disease. Unfortunately, 5% of statin users experience adverse events (mainly gastrointestinal \[GI\] and muscular). Statins inhibit not only cholesterol synthesis, but also synthesis of other substances in the mevalonate pathway. Among these other substances are Q10 and selenoproteins. It is well known that serum Q10 levels decrease during statin therapy, and that Q10 supplement inhibits this decrease. One study has shown reduction of Q10 in blood-platelets during statin therapy. Q10 is an important element in the mitochondrial respiratory chain. Depletion of Q10 leads to a reduction of high energy phosphates, anaerobe metabolism and mitochondrial dysfunction. This is suggested to be the cause of muscular adverse events in statin therapy. There are several reports of individuals relieved from muscular adverse effects after Q10 supplement, but no randomized, placebo controlled studies have been conducted. Symptoms of selenoprotein deficiency are very similar to adverse events seen in statin therapy, but no clinical trials have been conducted to evaluate the effect of selen supplement on adverse effects of statin therapy.
