It’s startling how much debate and disagreement exists about the guidelines for statin use.
Back in November 2013, new guidelines were published by the American Heart Association and the American College of Cardiology. The 2013 guidelines represented a significant shift in cholesterol management: essentially moving away from targeting/treating to a specific cholesterol level and instead encouraging treatment of all individuals with a 10-year risk of heart disease of 7.5% or higher (for specifics, see my post, The NEW guidelines for cholesterol-lowering statin meds).
There then ensued heated arguments over the published Risk Calculator that yields that all-important 10-year level of heart disease risk. Indeed, clicking the AHA’s Heart Attack Risk Assessment page right now yields this frustrating error:
“We’re sorry, but this tool is currently unavailable. The Heart Attack Risk Calculator is being updated and will be available soon. Please check back!”
Luckily, the AHA’s Prevention Guidelines page with a link to the original calculator still exists, so you can still calculate your 10-year risk. (Note: if these links fail, try my RESOURCES page: I’ll try to keep the risk calculator links up-to-date there.)
Assuming one believes at least directionally in the AHA’s risk calculator (and I do), it’s important for those who can use the calculator* and assess your personal level of heart disease risk over the next 10 years. (* You cannot use the calculator if you have heart disease or take statins already. Read more about calculators here.)
Until yesterday, it was clear what to do with your resulting risk: if someone between 40-75** gets a 10-year risk of heart disease of 7.5% or more, statin therapy should be considered and discussed with a doctor. (** See full 11/2013 recommendations below.)
But yesterday, things got a little tricky for anyone whose risk is between 7.5% and 10%.
Because yesterday, the U.S. Preventive Services Task Force issued new guidance for the use of statins which is not exactly the same as the AHA 2013 guidelines. (The USPSTF guidelines were published in the Journal of the American Medical Association; read/download a PDF here).
- On the plus side, the new USPSTF guidelines support the November 2013 AHA decision in that the new guidelines are also based on the 10-year risk calculator. So the USPSTF added weight to the argument for using 10-year risk calculator, and not treating by managing to a particular LDL cholesterol level.
- On the tricky side, the new USPSTF guidelines increased the risk of heart disease cutoff from 7.5% to 10%.
So now it’s not entirely clear what someone with a risk rate of 7.5%-10% should do. And whether insurance will cover statins for those individuals.
That’s because, as Ariana Eunjung Cha of The Washington Post astutely points out in her excellent article, New Statin Guidelines: Everyone 40 and older should be considered for the drug therapy, both Medicare and the Affordable Care Act use USPSTF recommendations to guide drug coverage plans. So that MAY call into question whether insurance companies will cover statin drugs for those in the 7.5% to 10% risk group.
In the end, what’s important is this: calculate your 10-year risk of heart disease. Use the calculator, and:
- If you’re below 7.5%, make sure to keep pursuing a lo-co lifestyle with frequent exercise and a healthy, low-fat, low-sugar, plant-based diet.
- If your risk is over 10%, get thee to a doctor and discuss statins.
- If your risk is between 7.5% and 10%, talk to your doctor or cardiologist about what next steps are right for you.
It all starts with your risk: calculate it! It’s so easy – all you need is your latest cholesterol results and systolic blood pressure (the first number). Then review your personal results and make a plan with your doctor.
** November 2013 AHA recommendation: if you are in one of the following four groups, you have elevated heart disease risk and should take statins:
- those who already have cardiovascular disease
- anyone with LDL (bad) cholesterol of 190 mg/dL or higher
- anyone between 40 and 75 years of age who has Type 2 diabetes
- people between 40 and 75 who have an estimated 10-year risk of cardiovascular disease of 7.5 percent or higher.
The USPSTF November 2016 recommendation:
“The USPSTF recommends that adults without a history of cardiovascular disease (CVD) (ie, symptomatic coronary artery disease or ischemic stroke) use a low- to moderate-dose statin for the prevention of CVD events and mortality when all of the following criteria are met: 1) they are aged 40 to 75 years; 2) they have 1 or more CVD risk factors (ie, dyslipidemia, diabetes, hypertension, or smoking); and 3) they have a calculated 10-year risk of a cardiovascular event of 10% or greater.”
