Quoted message said:Aims Muscular problems are the major group of side-effects
during statin treatment. They are known to occur much more
frequently during and after exercise. Methods and results
For the last 8 years we have monitored 22 professional
athletes in whom, because of familial
hypercholesterolaemia, treatment with different statins was
attempted. Only six out of the 22 finally tolerated at
least one member of this family of drugs. In three of these
six the first statin prescribed allowed training
performance without any limitation. Changing the drug
demonstrated that only two tolerated all the four or five
statins examined (atorvastatin, fluvastatin, lovastatin,
pravastatin, simvastatin). Cerivastatin was not among the
statins prescribed. Conclusions These findings indicate
that in top sports performers only about 20% tolerate
statin treatment without side-effects. Clinical decision
making as to lipid lowering therapy thus becomes a critical
issue in this small subgroup of patients.

This summary raises so many questions it seems unwise
to draw any conclusions. Maybe when the study is
finished . . . .
Some questions:
What sports were involved? Nordic skiers might be expected
to have quite different skeletomuscular problems from
golfers or swimmers, as well as very different training
modalities and intensities.
How large a pool were the 22 drawn from?
How were they chosen? Did they self-present with
perceived problems, or was there a random process or were
they referred?
If they self-presented or were referred, what were the
patent complaints?
How long did each subject use each statin, and at what
dosage?
How soon were effects noticed?
Did treatment continue the entire eight years, or was it
ended earlier?
After at least three tolerated the first statin they were
treated with and six tolerated at least one of the five,
what was the object of testing all subjects for tolerance to
all five statins?
Why these five statins and no others? Why was
cerivastatin excluded?
The implication is that some subjects experienced inability
to continue their athletic training. What is the
correspondence between inability to do athletic training at
an elite level and patients whose daily physical activity is
less demanding?
The 22 subjects were a "small subgroup" of patients. Who
were the other patients, were they being treated, or did
they constitute a control group?
Do adverse effects in a small subgroup justify the subject:
"Professional athletes suffering from familial
hypercholesterolaemia *rarely* [my emphasis] tolerate statin
treatment because of muscular problems."
