Wider
Guidelines Urged for Statins*
Prescribing
statins for people with type 2 diabetes irregardless of cholesterol
levels.
These
findings should tear up the rule-book on statin prescribing,"
says Richard Horton, editor of the Lancet. "This marks a major
conceptual shift in our understanding of the prevention of heart
disease."
July
5, 2002 -- Imagine a simple pill saving hundreds of thousands of
people from heart attack and stroke across the globe. That's what a
major new study says would happen if cholesterol-lowering statin drugs
were prescribed to the millions of at-risk individuals who could
benefit from them.
Researchers
say prescribing statins to a wider range of people could reduce heart
attack and stroke rates by at least a third. Until now, statins have
been primarily used to treat people who have high cholesterol levels.
But
the results of the British Heart Protection Study (HPS) show statins
also reduce risks for people with diabetes, narrowing of the arteries
(the major cause of heart disease), and a history of stroke. Even more
importantly, researchers say the inexpensive medications can also
protect people with normal or low cholesterol levels. And they work as
well in women and the elderly as they do in men and younger people.
"The
clear message from this study is: 'Treat risk -- not cholesterol
level,'" says Charles George, medical director of the British
Heart Foundation, in a news release. He says the results of the study
call for a review of the guidelines on statin use issued by government
and professional organizations, such as the U.S. National Institutes
of Health and American Heart Association.
Researchers
say guidelines should be changed so that a statin is considered for
use in anyone at increased risk for heart attack or stroke regardless
of cholesterol level.
The
study examined the effects of statin use in more than 20,000 men and
women between the ages of 40 to 80 with various risk factors for heart
disease. After five years, the risk of heart-related deaths was
reduced by 18% among those who received statins. People who took
statins were also 25% less likely to suffer a nonfatal heart attack or
stroke or require heart bypass surgery.
"HPS
shows unequivocally that statins can produce substantial benefit in a
very much wider range of high-risk people than had been previously
thought," says study author Rory Collins of the University of
Oxford Clinical Trial Unit, in the release.
"If
now, as a result, an extra 10 million high-risk people were to go onto
statin treatment, this would save about 50,000 lives a year -- that's
a thousand each week," says Collins. "In addition, this
would prevent similar numbers of people from suffering non-fatal heart
attacks or strokes."
The
complete report appears in the July 6 issue of The Lancet.
Richard
Horton, editor of The Lancet, says, "These findings should
tear up the rule book on statin prescribing. They are the most
important and far-reaching results for the treatment and prevention of
heart disease and stroke that we have seen in a generation.
"Previously
there has been concern that statins have been used too much; after the
results of HPS have been published there should be concern that they
may not be used enough in the future," says Horton.
Previous
studies on statins have not included many women or people over the age
of 70. But researchers say those groups were well represented in this
study, and statin use was safe and effective for all.
The
study also looked at the effect of using antioxidant supplements, such
as vitamins E and C and beta-carotene, in people at risk for heart
disease. But researchers found taking these supplements did not
provide any significant reduction in risk for heart attack, stroke,
cancer, or other major events.
Statin drugs include Pravachol, Lescol, Lipitor, Zocor.
