Hyperlipidemia and HTN Flashcards
Most cholesterol is made in
Liver
LDLs do what?
Carry cholesterol from the Liver (where it’s made) to the body’s cells
HDL’s job
collect chol from bodys tissues and return it to the Liver
Chylomicrons
carry lipids from DIET
VLDLs carry
Triglycerides
Familial Hypercholesterolemia conditions
Tx w Statin
Secondary Hyperlipidemia
Risk factors
DM Exc Alcohol Smoking Obesity Hypothyroid CKD Liver dz Meds
What is more common- Secondary Hyperlipidemia or Inherited/genetic Hyperlipidemia?
Inherited
When to screen for High cholesterol?
9-11 YO
and again at
17-21 YO
When to screen lipids
age 9
age 17
Coronary Heart Dz Risk factors
HTN >140/90 DM Tobacco use Obese Hyperlipidemia HDL <40
What is affected more by eating: cholesterol or Triglycerides?
Trig way more, and since they are taken at the same time, this is why the labs are supposed to be FASTING
Total cholesterol includes
HDL + LDL + Trig/5
Cholesterol, LDL, and HDL levels can be falsely low after what?
MI
Acute coronary event
Desirable LDL level
60-130
many sources say <100
Normal LDL level
<100
Desirable Total Cholesterol
<200
Desirable HDL level
> 60
Normal HDL level for female
> 50 (or equal to)
Normal HDL level for male
> 40 (or equal to)
Approach to Lipid mgmt
Diet
Exercise
Meds
Diet for Elevated Lipids:
DASH
“Dietary approaches to stop HTN”
Rich fruits and veggies Moderate in low fat dairy Low animal protein Plant source of protein Low sodium
Benefits of DASH diet
Decrease BP
Decrease LDL
Decrease risk of CHD and Stroke
Exercise can increase HDL levels
3-4 sessions/week
40 min of mod-vigorous
What are Statins
HMG Co-A reductase inhibitors
How do Statins work
Stabilize vulnerable plaques and reduce underlying inflammation
Statin mechanism
Stop HMG-Co A Reductase enzyme from working in the Liver
This is the Rate limiting step in Cholesterol production
When should pts take Statins
Bedtime
SE/ risk of Statins
Liver toxic
Mild GI
Myalgia, Myositis, Myopathy –> RHABDO!!!!
muscle stuff
CONTRA to giving Statins
Pregnant
Active Liver dz
What labs do you need to take before starting a Statin?
Lipid panel
LFT (live fx)
Creatine kinase
How often to get labs after starting Statins?
every 4-12 wks at first
What Lipid med is Safe during Pregnancy
Bile Acid Seq
Synergistic w Statin
Bile Acid Seq
What is the bad thing about Bile Acid Seq?
Can increase Triglycerides
DO NOT USE if Trig are already >400, and caution use if they are >200
Niacin
increase HDl
SE: Flushing, liver damage, not rec to use w statin
Fibric Acid Derivative
- Gemfibrozil
- Fenofibrate
- Bezafibrate
Best known for LOWERING TRIGLYCERIDES
raise HDL
Meds that affect Triglycerides
Fibric Acid: good bc they LOWER triglycerides
Bile Acid: bad bc they can increase triglycerides
Fibric Acid Deriv
contra
Pre-existing Gallstones
Don’t use w other statin, Myopathy risk (muscle)
Ezetimibe
Block absorption of cholesterol
ADJUNCT for Statin
Contra to Ezetimibe
Active Liver dz
Pregnancy
PCSK9 Inhib
- Evolocumab
- Alirocumab
EXPENSIVE, requires injections
but very effective at lowering LDL, increasing role as Adjunct tx to Statins
