Step 1: Determine and classify lipoprotein levels
ATP Classification of LDL, Total, and HDL Cholesterol
LDL Cholesterol < 100 mg/dL Optimal
100-129 Near Optimal130-159 Borderline High160-189 High>/= 190 Very High

Total Cholesterol<200 mg/dL Desirable
200-239 Borderline high>/= 240 High
HDL Cholesterol< 40 mg/dL Low
>/= 60 High

Step 2: Identify presence of clinical atherosclerotic disease
o Clinical CHDo Symptomatic coronary artery
diseaseo Peripheral artery diseaseo Abdominal aortic aneurysm

Step 3: Major Risk Factors
o Cigarette smokingo Hypertensiono Low HDL cholesterol (<40 mg/dL)o Family history of premature CHD male: <55 years; female: <65 years o Age: men >/=45 years;
women >/= 55 years

Step 4: Determine risk category

Therapeutic Lifestyle Changes
o Weight managemento Increase physical activityo TLC diet
- Saturated fat < 7% of calories - Cholesterol < 200 mg/dL- Fiber 10-25 g/day
![Page 8: DYSLIPIDEMIA](https://reader036.fdocuments.in/reader036/viewer/2022070423/56816682550346895dda278d/html5/thumbnails/8.jpg)
Model of Steps in Therapeutic Lifestyle Changes
Visit 1: Begin lifestyle therapies6 weeks
Visit 2: Evaluate LDL response If goal not
reached,intensify LDL-lowering therapy
6 weeks
![Page 9: DYSLIPIDEMIA](https://reader036.fdocuments.in/reader036/viewer/2022070423/56816682550346895dda278d/html5/thumbnails/9.jpg)
Visit 3: Evaluate LDL response If LDL goal not reached,
consideradding drug therapy
Q 4-6 weeks
Visit N: Monitor adherence to TLC

Progression of Drug Therapy in Primary Prevention
Initiate LDL-lowering therapy6 weeks
If LDL goal not achieved,intensify LDL-lowering therapy6 weeks

If LDL goal not reached, intensify drug therapy
Q 4-6 mos
Monitor response and adherence to therapy

Identify metabolic syndrome and treat, if present after 3 months of TLC:
Risk Factor Defining LevelAbdominal Obesity Men Women
Waist circumference >102 cm (>40 in) >88 cm (>35 in)
Triglyceride >/= 150mg/dLHDL cholesterol Men Women
<40 mg/dL < 50 mg/dL
Blood pressure >/=130/>/=85mmHg
Fasting Glucose >/= 110 mg/dL

Treatment of Metabolic Syndrome
Treat underlying causes-Intensify weight management-Increase physical activity
Treat lipid & non-lipid risk factors-Treat hypertension-Use ASA for CHD patients -Treat elevated TG and/or low HDL
![Page 18: DYSLIPIDEMIA](https://reader036.fdocuments.in/reader036/viewer/2022070423/56816682550346895dda278d/html5/thumbnails/18.jpg)
Treat elevated triglycerides:
ATP III Classification of Serum TG (mg/dL)
<150 Normal150-199 Borderline high200-499 High>/= 500 Very high

Treatment of elevated triglycerides (>/= 150mg/dL)
Primary aim of therapy is to reach LDL goalIntensify weight managementIncrease physical activityIf TG is >/=200mg/dL after LDL goal is reached,set secondary goal for non-HDL cholesterol 30mg/dL higher than LDL cholesterol
![Page 20: DYSLIPIDEMIA](https://reader036.fdocuments.in/reader036/viewer/2022070423/56816682550346895dda278d/html5/thumbnails/20.jpg)

Treatment of Low HDL Cholesterol (40 mg/dL)
Reach LDL goalIntensify weight management and increase physical activityIf TG 200-499 mg/dL,achieve non-HDL
goalIf TG < 200 mg/dL in CHD or CHD equivalent consider nicotinic acid or fibrate
