Background

ACC/AHA published new cholesterol and cardiovascular risk
assessment guidelines in 2013. 1

This is an overview of the 2013 ACC/AHA guidelines and a
comparison to preceding guidelines.

ATP III Lipid and
Lipoprotein Classification
(The “Old Familiar Classification”)
LDL Cholesterol (mg/dL)
<100
100–129
130–159
160–189
190
Optimal
Near optimal/above optimal
Borderline high
High
Very high
Old vs. New: Lifestyle Modification
New guidelines:
Diet: healthy pattern
DASH, USDA , AHA Diet
Calorie requirements, personal and
cultural preferences, and nutrition
therapy for other medical
conditions

Old guidelines:

Diet: low fat and
low cholesterol

regular exercise habits
avoidance of tobacco products
maintenance of a healthy weight


Old vs. New: Statin Eligibility
Old
New
Age
Statin eligible
groups
1 ≥21 years
Clinical CVD
2 ≥21 years
LDL-C ≥190 mg/dl
3 40-75 years +LDLC 70-189 mg/dl
Diabetes
4 40-75 years + LDLC 70-189 mg/dL
High CVD risk
≥7.5%, 10 years,
CHD or stroke
Determining Risk for the 4th Group
New Pooled Cohort Equations to estimate 10-year risk
 Adults 20-79 years of age who are free from ASCVD
 4 racially and geographically diverse cohorts
 ASCVD risk: heart disease and stroke
 Calculated from sex, age, race, total cholesterol, HDL
cholesterol, systolic blood pressure, and whether on
treatment for high blood pressure, has diabetes, or is a
smoker
See Flowchart (addendum)
New: Classification of Statin Intensity
Intensity of statin therapy: is defined as a daily dose that
lowers LDL-C by

High-intensity: by 50%

Moderate-intensity: by 30% to <50%
New: Intensity Instead of Levels
What about the Rest?


There are people who may benefit from statin therapy who
do not fall into one of the four groups.
As with other guidelines, clinicians may use their judgment
in considering other factors such as:
• family history of ASCVD.
 biomarkers such as C - reactive protein.
 ankle-brachial index, etc.
Summary




Statin is the first line therapy.
Statin eligible groups based on benefit, not only on the LDLC measurement.
Treatment is based on statin intensity instead of specific
treatment goals for blood cholesterol.
New global risk assessment tool.
Healthy Dietary Patterns (servings per day unless
specified) (2000 kcal)
Implications

High cholesterol is a major and controllable risk factor for
heart attacks and strokes.

One goal of the ACC/AHA guidelines is to better identify and
focus statin therapy on those who are most at risk for (or
have) ASCVD.
Implications

We have much room for improvement for increasing the
level of healthy lifestyles and statin therapy even among
those most at risk.

We can use the guidelines to identify those who do not yet
know they are at risk, and increase healthy lifestyle choices
and statin therapy for those who are.
Program Considerations

New performance measures for cholesterol are in the
development phase.
Right now, we can:
 Increase adaptation of healthy lifestyle and levels statin
therapy for those who do know they are at risk.
 Help them adhere to that therapy for the rest of their longer
lives.
