UNIT 4 Antihyperlipidemic/Hypolipidemic Drugs Pt.1

🫀 Important Lipid (Cholesterol/Fat) Terminology — EASY Breakdown

🧈 Cholesterol

What is it?

➡ A fat-like substance your body needs to work properly.

Why do we need it?

Cholesterol is a building block for:

• 🧬 Steroid hormones (made by adrenal glands)

  • Cortisol (stress hormone)

  • Aldosterone (controls blood pressure)

  • Sex hormones

Memory Trick:

“CHOLESTEROL = CHOICES for hormones”
➡ Your body uses cholesterol to choose and create hormones .

🩸 Hyperlipidemia

Break the word apart:

• Hyper = high

• Lipid = fat

• -emia = in the blood

Meaning: ➡ Too much fat in the blood

Includes high levels of:

• Cholesterol

• Triglycerides

Why is it a problem?

Too much fat can build up inside arteries → forms plaque → blocks blood flow.

“HYPER = HIGH FAT FLOATING”
➡ Hyperlipidemia = too much fat floating in your blood.

💊 Hypolipidemic / Antihyperlipidemic Drugs

Break it down:

• Hypo = lower

• Anti = against

• Lipid = fat

Meaning:

➡ Medications that lower blood fats

They help decrease:
✅ Cholesterol
✅ Triglycerides
✅ Risk of artery blockage

Memory Trick:

“ANTI-HYPER = FIGHT HIGH FAT”
➡ These drugs fight high lipid levels.

🫀 Important Lipid (Cholesterol/Fat) Terminology — EASY Breakdown

🍳 Dietary Lipids (Fats from Food)

Dietary lipids are fats we eat that the body uses for important jobs.

They help make:

1. 🧱 Cell Membranes

• Lipids create the outer layer of cells

• Helps cells stay strong and function

“Lipids = Cell's Protective Coat”

2. 🧠 Nerve Tissue

• Fats help protect and support nerves

Think:

“Fat = Fuel for the Brain & Nerves”

3. 🚚 Plasma Lipoproteins

Lipoproteins are transport vehicles that carry fats through blood.

Think:

LIPOPROTEIN = LIPID TAXI 🚕
➡ It carries fats around the body.

🫀 Important Lipid (Cholesterol/Fat) Terminology — EASY Breakdown

🧈 Types of Dietary Lipids

1. Fatty Acids What are they?

➡ Building blocks that make fats.

They are the “pieces” that create larger fats.

“Fatty acids = Fat pieces”

2. Triglycerides What are they?

➡ The main type of fat stored in the body.

Made of:

• 3 fatty acids + glycerol

Job:

✅ Stores energy
✅ Provides fuel when needed

“TRI = 3 fats together”
➡ Triglyceride = 3 fatty acids attached.

3. Cholesterol Job:

Used to make:

• Hormones

• Cell membranes

• Other important substances

“Cholesterol builds, but too much blocks.”

🫀 Important Lipid (Cholesterol/Fat) Terminology — EASY Breakdown

🚨 What Happens When There Is Too Much Fat?

Step 1:

You eat extra fat 🍔

⬇

Step 2:

Body stores extra fat 🧈

⬇

Step 3:

Too much fat starts sticking inside arteries 🩸

⬇

Step 4:

Plaque forms

⬇

Step 5:

Blood flow becomes restricted

🧱 Atherosclerosis

What is it?

➡ Hardening/narrowing of arteries because of fatty plaque buildup

Think:

“Athero = Artery trouble”

Plaque is like:
🚰 Grease clogging a pipe

The artery becomes:

• Narrower

• Less flexible

• Harder for blood to pass through

🫀 Important Lipid (Cholesterol/Fat) Terminology — EASY Breakdown

⭐ BIG PICTURE MEMORY LINE:

“Lipids build the body, but too much blocks the body.”

✅ Cholesterol → makes hormones & cells
✅ Triglycerides → store energy
✅ Fatty acids → building blocks of fats
✅ Hyperlipidemia → too much fat in blood
✅ Antihyperlipidemics → lower fat levels
✅ Excess fat → plaque → atherosclerosis → reduced blood flow

Quick Exam Tip 📝:

High lipids = High plaque risk = High cardiovascular risk ❤

• Store excess fat, but eventually interferes with blood flow as fat lines the arteries (plaque, atherosclerosis)

🩸 Types of Lipoproteins — EASY Breakdown

🚕 What are Lipoproteins?

Break the word:

• Lipo = fat

• Protein = carrier

Meaning:

➡ Lipoproteins are “transport trucks” that carry fats through the blood.

They carry:

• 🧈 Cholesterol

• 🧈 Triglycerides

They take fats:
✅ To places where the body needs them
✅ To storage areas

“LIPOPROTEINS = LIPID TAXIS 🚕”
➡ They pick up fats and deliver them around the body.

Types of Lipoproteins

⭐ The Main Lipoproteins

⭐ The Main Lipoproteins

Think of them as having different jobs:

🟦 HDL = “Healthy” Cholesterol (Protective Lipoprotein)

HDL = High-Density Lipoprotein

Job:

➡ Picks up extra cholesterol from the blood and takes it back for removal.

Think:
🧹 HDL = The cleanup crew

It helps:
✅ Remove cholesterol
✅ Clear triglycerides
✅ Protect arteries

Higher HDL = Better ❤

More HDL → less plaque buildup → lower cardiovascular risk

How to Increase HDL:

🏃 Exercise
🐟 Omega-3 fatty acids (fish oils)
🍷 Moderate alcohol intake (if appropriate)

“HDL = Helps Defend the Heart” ❤

or

“H = Healthy Helper”

•  (protective; rapid clearance of cholesterol and triglycerides) – exercise, omega-3 fatty acids/fish oils, mod alcohol intake; higher levels decrease the risk of cardiovascular disease

Types of Lipoproteins-carrier proteins

Types of Lipoproteins

🟥 LDL = “Lousy” Cholesterol (Plaque Builder)

LDL = Low-Density Lipoprotein

Job: ➡ Carries cholesterol to body tissues.

The problem:
❌ Too much LDL leaves cholesterol behind in arteries.

This causes:
➡ Plaque buildup
➡ Narrow arteries
➡ Reduced blood flow
➡ Increased cardiovascular risk

“LDL = Leaves Deposits in arteries” 🧱

or

“L = Lousy because it Loads up arteries”

🟧 VLDL = Very Bad Delivery Truck

VLDL = Very Low-Density Lipoprotein

Job:

➡ Carries mainly triglycerides through the blood.

Problem:
❌ High levels contribute to plaque formation.

High VLDL → more fat available to build plate

“VLDL = Very Dangerous Lipid Delivery”

🫀 HDL vs LDL/VLDL (Easy Comparison)

Types of Lipoproteins

Lipoprotein	Job	Good or Bad?	Remember
🟦 HDL	Removes cholesterol	✅ Good	H = Healthy Helper
🟥 LDL	Delivers cholesterol	❌ Too much is bad	L = Leaves plaque
🟧 VLDL	Carries triglycerides	❌ High levels are bad	Very bad when high

“HDL = Hauls cholesterol away” 🚚⬅

(removes it)

“LDL = Leaves cholesterol behind” 🧱

(builds plaque)

“VLDL = Very Loaded with fat” 🧈

(carries triglycerides)

HDL = The cleaner 🧹 → protects your heart
LDL/VLDL = The builders 🧱 → can create plaque

⭐ “Higher HDL helps the heart; higher LDL/VLDL clogs the cart.” 🫀

🫀 Recommended Cholesterol Levels — EASY Breakdown

Think of cholesterol numbers like a report card for your heart ❤

Some fats should be LOW (because they clog arteries), and one should be HIGH (because it protects you).

🟥 LDL (“Lousy” Cholesterol) Goal:

✅ Below 100 mg/dL

Why?

LDL can leave cholesterol behind in arteries → plaque buildup.

“LDL = Leave it Low” ⬇

➡Low LDL = happier arteries 🩸

🟧 VLDL (“Very Loaded” Cholesterol) Goal:

✅ Below 40 mg/dL

Why?

VLDL carries triglycerides, and high levels can contribute to plaque.

“VLDL = Very Dangerous if it's Very Large”

➡ Keep VLDL low!

🟦 HDL (“Healthy” Cholesterol) Goal:

✅ Women: Greater than 60 mg/dL
✅ Men: Greater than 40 mg/dL

Why?

HDL removes extra cholesterol from the blood and protects arteries.

“HDL = Higher is Helpful” ⬆❤

More HDL = more protection

⚠ Low HDL Warning

If HDL is:
❌ Below 40 mg/dL

➡Risk of heart disease increases

Memory Trick: “HDL below 40 = Heart Risk at the door 🚪❤”

🫀 Recommended Cholesterol Levels — EASY Breakdown

side by side

🧈 Triglycerides Goal:

✅ Less than 150 mg/dL

Why?

High triglycerides increase the chance of fat buildup in arteries.

“TRI should stay under 150”

🩸 Total Cholesterol Goal:

✅ Less than 200 mg/dL

This is the total amount of cholesterol in your blood.

Includes:

• LDL

• HDL

• Other cholesterol particles

“Total under 200 keeps the heart strong.” ❤

Lipid	Goal Level	Easy Reminder
🟥 LDL	<100 mg/dL	LDL = Leave it Low
🟧 VLDL	<40 mg/dL	VLDL = Very Low is better
🟦 HDL	>60 women / >40 men	HDL = Higher Helps
🧈 Triglycerides	<150 mg/dL	TRI stays under 150
🩸 Total Cholesterol	<200 mg/dL	Total under 200

❤ “GOOD GOES UP, BAD GOES DOWN”

⬆ HDL = HIGH (good)
⬇ LDL + VLDL + Triglycerides = LOW (bad when high)

“Keep the L's Low (LDL & VLDL), Keep HDL High, and keep Total under 200!” 🫀

• Triglycerides levels should be less than 150 mg/dl

• If HDL below 40 mg/dl---increase risk of heart disease

• Total cholesterol Levels should be less than 200 mg/dl

🫀 Atherosclerosis — Easy Short Summary

Atherosclerosis = Plaque buildup inside artery walls 🧱🩸

➡ Plaque makes arteries narrow and stiff
➡ Less blood and oxygen can reach organs

Can lead to:

❤ Angina → Chest pain from reduced blood flow to the heart

❤ CHF (Congestive Heart Failure) → Heart struggles to pump blood

❤ MI (Myocardial Infarction/Heart Attack) → Blocked blood flow causes heart muscle damage

🧠 Cerebral Artery Disease → Stroke → Reduced blood flow to the brain

🦵 Peripheral Artery Disease (PAD) → Poor blood flow to arms/legs

🫘 Renal Artery Insufficiency → Reduced blood flow to kidneys

Memory Trick:

“Plaque blocks the pipes → organs lose oxygen.” 🧱🚰

Atherosclerosis = blocked arteries → heart, brain, legs, kidneys affected.
