Introduction
Hypercholesterolemia- Why do we Care?1. Affects 65 Million U.S. Adults
2. Independent Risk Factor for CHD
3. CHD #1 Killer in U.S.
4. My fianceé has it
>200 mg/dl Total Cholesterol
LDL>130 HDL<40 mg/dl

Don’t We Already Have it
Figured Out?
1. ONLY worry about LDL
2. If LDL is high- Put ALL PatientsONLY on a Statin for life
3. Pat yourself on the back when LDLis decreased and forget about your
patients who die of heart attacks
despite being on a statin

Men’s Health, June 2001
“He hasn’t been trained in the latesttechnology.”
“He isn’t aware of the latest treatment.”
“The test that he relies on will miss 8 outof 10 cases.”
“Yet the enemy he is fighting is heart
disease, the leading killer of men.” “Who is he?”
“He’s your doctor.”

*Coronary heart disease or peripheral vascular disease (including symptomatic carotid artery

** Other risk factors for coronary heart disease (CHD) include: age (males > 45 years, females > 55years or premature menopause without estrogen replacement therapy); family history of premature
CHD; current cigarette smoking; hypertension, confirmed HDL-C < 35 mg/dL (< 0.91 mmol/L); and
diabetes mellitus. Subtract 1 risk factor if HDL-C is > 60 mg/dL (> 1.6 mmol/L).

2. HMG- CoA Reductase Inhibitors
(Statins)
New Treatment Methods
1. Niacin
2. Niacin + Statin

http://slidepdf.com/reader/full/niacin-presentation 12/41
Current Treatment Methods
1. Exercise and Dieta. Poor compliance
b. Usually cannot get to target levels
2. Statins
a. Great at lowering LDL levels
b. Not much affect on Lipoprotein(a), HDL,or small dense LDL, and minor effects on
Triglycerides

Who Cares?
The National Cholesterol EducationalPanel (NCEP) Cares and in 1993-Began focusing more on other major
lipids in addition to LDL1
This In-Depth Study Revealed aPlethora of Information related to CHDRisk

Lipid Parameter Function:
Latest Commentary1
VLDL
Carries triglycerides to peripheral cells
High levels may be associated with increased CHD risk2
LDL
Carries cholesterol to cells
High levels linked to increased CHD risk
Primary target of cholesterol-reducing therapy3
HDLRemoves cholesterol from cells
High HDL considered protective against CHD
HDL >60 mg/dL decreases CHD risk1
Lipoprotein(a)
A complex of LDL and apolipoprotein(a)Prevents LDL from being taken up by the Liver
Elevated Lp(a) is an independent risk factor for premature CHD4
Triglycerides
A neutral fat stored in adipose cells
Positively correlated with risk for CHD1

Your Patients Care Too, Because:
25% of Men with a FH of CHD:
1st Sign of Heart Disease is SuddenDeath
50% of arteriosclerosis can’t beexplained by standard risk factors(smoking, diet, lifestyle, and highcholesterol)
80% of people who develop CHD havethe same basic cholesterol numbers as
those who don’t have CHD

HDL
Has been shown to be Cardioprotective in theFramingham Heart Study, and inretrospective analyses of intervention trialssuch as the Coronary Primary Prevention
Trial and the Multiple Risk Factor InterventionTrial 5-7
The data were consistent with a 2% to 3%
decrease in CHD risk for each 1 mg/dLincrease in HDL, after adjustment to controlfor other risk factors.

VA- HIT Study on HDL8
The importance of raising HDL to reduce morbidity and mortality
was clearly confirmed with the publication August 1999 in the NEJM of the findings of the landmark Veterans Administration High Density
Lipoprotein Intervention Trial (VA-HIT) clinical outcome study.

Niacin (9, 10, 11)
Increases HDL by up to 26%
Decreases LDL by up to 17%
Decreases TGs by up to 35%
Decreases Lp(a) by up to 27%

The Uniqueness of Niacin
Increases HDL better than ANY other medication and increases HDL2b themost
Only drug that has been shown toswitch subclasses of LDL from smalldense (IIIa and IIIb), to large buoyant
(Pattern B to Pattern A)
Decreases Lp (a) the best of any
medication

Why Isn’t Everyone on Niacin!?!
Main Reason- Flushing
Difficult Dosing (TID)
It’s too cheap (No $$$ for Drug
companies)

Flushing Tips
When beginning or increasing dose- take
400mg Ibuprofen (or equivilant Naproxen or Aspirin) 30 min before Niaspan®
Avoid Hot drinks, Hot shower, or spicy foods
1 hr before or anytime after Niaspan® dosing
Eat a low-fat snack with Niaspan®
Take right before going to bed

Combination Therapy
Niaspan®
+ Statin(12,13,14, 15)
1. Has been proven safe and effective in
many trials
2. Some early trials with OTC sustained
release Niacin showed some
rhabdomyolysis and mild increase in
LFTs
3. No rhabdomyolysis or increase in LFTshas been shown with Niaspan® in
combination with a Statin

Summary
7/29/2019 Niacin Presentation
http://slidepdf.com/reader/full/niacin-presentation 32/41
Summary LDL is not the only Lipoprotein that should be
considered for CHD Risk- HDL, TGs, Lp(a) should be
evaluated and consideration should be given toLDL/HDL sub-class testing with a strong FH of
sudden cardiac death
Niaspan® is close to a “Magic Bullet” by moving ALLLipoproteins in the right direction, especially HDL,
and doing positive things in areas we are not
currently testing like Lp(a) and LDL/HDL subclasses
Advicor™- is being shown to have phenomenal
effects on the Lipid profile and (pending FDA
approval in the second half of 2001) will become a
formidable weapon in the war against CHD
