Do Hypolipidemic Drugs Lower Medical Expenses?
Joel M. Kauffman, Ph.D.
In a recent review by Tsuyuki and Bungard (1) noncompliance with
prescribed hypolipidemic agents was said to have annual associated
costs of $25-100 billion in the US alone. How could this be possible?
If statin drugs in particular changed the cause of death to sudden
fatal hemorrhagic stroke, for example, rather than some form of
cardiovascular disease (CVD), then a medical cost saving is possible;
but I have not seen such a claim, thus the most that can be expected
of statin drugs is to postpone the inevitable. In the CARE trial
the relative risk of breast cancer in the treatment group was +1500%
(absolute risk +4.2%); but the medical costs of breast cancer are
probably comparable with those of CVD. Even if the statin drugs
increased lifespan by a number of years, most of the people taking
them will eventually die of CVD or cancer anyway, so the largest
reduction in cost that could be expected would be a hiatus for a
number of years followed by the same costs as before. In addition,
the costs of the statin drugs of about $1,000 per year per person
for 20-30 years would be added permanently.
Tsuyuki and Bungard
wrote that ...numerous randomized controlled trials have conclusively
established the efficacy of aggressive cholesterol reduction in
decreasing mortality...Despite this robust evidence of efficacy...
How much do statin drugs increase lifespan? In the EXCEL trial of
lovastatin, after 1 year the total death rate in the treatment group
went up +0.3% absolute. In the 4S trial of simvastatin, after 5.4
years the total death rate went down 3.3%, or -0.6%/year. In the
WOSCOPS trial of pravastatin, after 4.4 years, the total death rate
went down 0.9%, or -0.2%/year. In the CARE trial of pravastatin,
after 5 years, the total death rate went down 0.77%, or -0.15%/year.
In the AFCAPS/TexCAPS trial of lovastatin, after 5.2 years, the
total death rate went up 0.09%, or +0.02%/year. In the LIPID trial
on pravastatin, after 6.1 years, the total death rate went down
3%, or -0.49%/year.2 In the MIRACL trial on atorvastatin for secondary
protection, after 2.5 years, there was no change in the total death
rate. (3) Taking the mean of these results of these 7 trials, the
absolute risk is -0.16%/year. Assuming a 20-30-year treatment period
in which the non-CVD deaths do not increase, of which we will know
nothing for 10-15 more years, the increase in life expectancy on
treatment with statin drugs would be about 4 months.
The assertion or
Tsuyuki and Bungard that Elevated serum cholesterol is well
known as a major risk factor for the development of CVD...[italics
added] may be true as written, but cholesterol as a cause of CVD
has been disproven decisively. (2,4) It has even been suggested
that elevated cholesterol is a protective reaction to elevated homocysteine
levels.5 After all, women with the highest cholesterol levels live
the longest. (2,4) Two recent reports confirmed that serum cholesterol
levels have no predictive value whatever in individuals for the
development of calcified plaques in arteries as found by electron
beam tomography. (6,7)
Serious consideration
should be given to halting the use of the statin drugs, or at least
not compensating the costs of their mass adminstration. Statin drugs
do not increase lifespan significantly and, with 10-15 more years
of trials completed, they might be found to decrease lifespan as
the toll in increased cancer rates is exacted. It is actually conceivable
that discontinuation of all anticholesterol treatments will actually
save $billions/year.
An even more extreme
view aired in the United Kingdom is that serum cholesterol level
is a relatively poor predictor of CVD, and that the many misclassifications
may have damaging psychological effects, and that in most cases,
even testing cholesterol level, as well as treating raised concentrations,
is a waste of National Health Service resources. (8)
