Hyperlipidemia

—

In one line

·In hyperlipidemia, the bedside team that spots silent vascular risk early — checking lipids, blood pressure, and family history — outperforms the team that waits for a stroke or heart attack.

Normal physiology

·Your liver makes cholesterol every day because your body needs it to build cell walls, make vitamin D, and create hormones. The liver packages cholesterol into tiny protein-coated balls called lipoproteins so it can travel through your watery blood. Low-density lipoprotein (LDL) delivers cholesterol out to tissues; high-density lipoprotein (HDL) picks up extra cholesterol and hauls it back to the liver to be recycled or flushed out in bile. Triglycerides come mainly from food and are packaged separately to fuel muscles. In a healthy system, LDL and HDL stay balanced, artery walls stay smooth, and blood flows freely.

What goes wrong

·In hyperlipidemia, your liver makes too much LDL, your cells cannot pull enough of it out of the blood, or your body does not make enough HDL to haul the extra away. The result is a traffic jam of fat particles in your bloodstream. Excess LDL seeps into the artery wall, where it oxidizes (goes rancid like old oil), triggers inflammation, and hardens into plaque.

Hallmark signs

Red flags · escalate now

·Chest pain, jaw pain, or shortness of breath—may signal a heart attack from a ruptured cholesterol plaque.
·Sudden face droop, arm weakness, or slurred speech—may signal a stroke from a blocked brain artery.
·Severe belly pain with vomiting—triglycerides above 500 mg/dL can cause pancreatitis, a life-threatening emergency.
·Yellow skin bumps (xanthomas) or cloudy eye rings (arcus) before age 45—often means familial hyperlipidemia with very high inherited cholesterol that needs urgent treatment to prevent early heart disease.
·New leg pain that does not go away with rest—may signal a clot or severe artery blockage cutting off blood to the limb.

Workup

·Lipid panel (total cholesterol, LDL, HDL, triglycerides) after 9–12 hour fast
·10-year ASCVD risk calculator (using age, sex, race, cholesterol, BP, diabetes, smoking)
·Hemoglobin A1c
·Basic metabolic panel (BMP) including creatinine and eGFR
·Liver function tests (ALT, AST) before starting statin
·Thyroid-stimulating hormone (TSH)

—

Treatment

·High-intensity statin (atorvastatin 40–80 mg or rosuvastatin 20–40 mg daily)
·Moderate-intensity statin (atorvastatin 10–20 mg, rosuvastatin 5–10 mg, simvastatin 20–40 mg, or pravastatin 40–80 mg daily)
·Ezetimibe 10 mg daily (added to statin if LDL remains ≥ 70 mg/dL on statin alone)
·PCSK9 inhibitor (evolocumab 140 mg SC every 2 weeks or alirocumab 75–150 mg SC every 2 weeks)
·Lifestyle modification: diet with < 7% calories from saturated fat, 25–35 g fiber daily, 150 minutes moderate aerobic exercise per week, weight loss if BMI ≥ 25
·Icosapent ethyl 2 g twice daily (if triglycerides 150–499 mg/dL despite statin)
·Fibrate (fenofibrate 145 mg daily) if triglycerides ≥ 500 mg/dL

NCLEX trap

·Hyperlipidemia is silent for years. Most people feel completely fine. We catch it by checking blood lipids during a routine visit, not by waiting for symptoms to appear.
·Diet helps, but most people with hyperlipidemia also need a statin (a medicine that blocks cholesterol-making in the liver). Using both together lowers cholesterol better than either one alone.
·Statins for hyperlipidemia are usually lifelong. Stopping the medicine lets cholesterol climb back up, and fat builds back up inside the artery walls.
·We look at the whole picture: total cholesterol, LDL (the bad kind that clogs arteries), HDL (the good kind that cleans them), and triglycerides (another fat in the blood). High LDL or high triglycerides is dangerous even if HDL looks okay.
·Cut down on saturated fat (butter, fatty meat) and trans fat (fried foods, packaged snacks), but healthy fats like olive oil, nuts, and fish actually protect the heart and help control hyperlipidemia.
·We check lipids regularly—usually every 3 to 6 months at first—to see if the medicine dose is working and to keep hyperlipidemia under control long-term.
