What's next for dyslipidemia management? The 2013 ACC/AHA Guidelines, the NLA recommendations, and beyond

To compare and contrast the 2013 American College of Cardiology (ACC)/American Heart Association (AHA) Guidelines and the 2014/2015 National Lipid Association (NLA) Recommendations for Management of Dyslipidemia in the context of evolving evidence.

Guidelines from the National Cholesterol Education Program (NCEP), ACC/AHA, and NLA; recent clinical trials involving non-statin therapies.

At the authors' discretion, preference was given to references focusing on guidelines and recent clinical trials involving dyslipidemia management.

In late 2013, the ACC/AHA released guidelines on the treatment of blood cholesterol to reduce risk for atherosclerotic cardiovascular disease (ASCVD) in adults. Reflecting contemporary evidence-based literature, low-density lipoprotein cholesterol (LDL-C) and non-high-density lipoprotein cholesterol (non-HDL-C) numeric treatment goals were eliminated, and a new method of risk assessment (the Pooled Cohort Equations) was recommended. The guidelines emphasized lipid lowering in 4 patient populations proven to benefit from statin therapy, recommending moderate to high-intensity statin dosing, with no additional drug therapies and limited ongoing monitoring. Clinical controversies ignited by these guidelines led to the publication of recommendations by the NLA in 2014 and 2015. Part 1 of the NLA recommendations incorporated parts of both the ATP III guidelines and the 2013 ACC/AHA guidelines along with updated original recommendations. These recommendations provided numeric LDL-C, non-HDL-C, and apolipoprotein B treatment goals and potential additional ASCVD risk factors, with stepwise risk assessment based on traditional cardiac risk factors and multiple assessment tools. In addition to statins, the 2014 NLA recommendations highlighted the benefit of additional or alternative lipid-lowering therapies. Part 2 of the NLA recommendations expanded the guidance for treatment of special populations and prioritized ezetimibe as a non-statin agent based on recent evidence. Finally, the US Food and Drug Administration recently approved 2 medications from a new class, the PCSK9 inhibitors, although their role in therapy remains unclear pending outcomes data.

We aim to highlight the core recommendations of recent guideline publications and to discuss similarities and differences in the context of the future management of dyslipidemia.
