In November 2013, the American
Heart Association (AHA) and the American College of Cardiology (ACC) released new guidelines
for cholesterol therapy in adults 20-79 years old. The guidelines were based on
solid medical evidence but, nonetheless, generated a lot of controversy and
even opposing opinions from experts in the field. On one hand, the guidelines
argue for limiting some of the cholesterol testing we now use as a guide for
therapy. On the other hand, the guidelines recommend therapy (the use of statin
drugs) for certain groups of patients, regardless of their blood cholesterol
levels. The controversy which evolved was covered in articles in the New York
Times last November. The two titles convey the opposing messages: Experts Reshape Treatment Guide for
Cholesterol and Don’t
Give More Patients Statins.
Some of the best known statin drugs
now in use include: Atorvastatin (Lipitor), Rosuvastatin (Crestor), Lovastatin
and Simvastatin.
A study on the subject was published in the New England Journal of Medicine of 3/20/2014
by Michael J. Pencina, PhD, from the Duke Clinical Research
Institute. It reports that the new
guidelines would increase the number of
U.S. adults eligible for statin therapy by almost 13 million, and that most adults
between 60-75 years old would become candidates for treatment. I also refer to
the guidelines in my blog of last November, Statins,
To Take Or Not To Take.
The guidelines use a newly updated, computerized cardiac
risk assessment tool, in deriving its recommendations. We use the same tool in
our office.
One has to remember that the guidelines are guidelines;
they are not iron clad rules. Each case has to be judged individually. In the
majority of cases, the guidelines should be followed. But there are exceptions.
A small percentage of people just can’t take statins because of side effects.
Others may be able to make lifestyle changes, such as diet modification, an
increase in physical activity and weight loss, which may mitigate against the
ill effects of high cholesterol. Others may have to be convinced that the benefits
of taking a statin outweigh the risks. Still others may have to be convinced
that they actually already have the beginnings of heart disease before they
agree to take the medication. And then there is that group of patients that
“just get away with high cholesterol.” Their families have had high cholesterol
for generations, and they live well into their nineties or longer. They are the
ones who wouldn't hear of statins…
When necessary, additional testing is done to further
assess you heart disease risk, such as specialty blood work, and coronary artery
calcium scoring.
So next time you’re in the office, ask about the new
cardiac risk assessment (it’s free), and see if you really need to take a statin
drug.
