Names & Terms You Will Hear
Plain-language meanings for the terms your care team may use.
| Term | Meaning |
|---|---|
| Cholesterol | A waxy, fat-like substance your body needs for cells, hormones, and bile. Made by the liver; some comes from food. |
| Lipid Panel | The blood test that measures cholesterol and triglycerides. Usually checked fasting, but a non-fasting test is fine for screening. |
| LDL | Low-density lipoprotein — the BAD cholesterol. Carries cholesterol into artery walls where it builds plaque. |
| HDL | High-density lipoprotein — the GOOD cholesterol. Carries cholesterol back to the liver to be cleared. |
| Triglycerides | Another type of fat in the blood. Comes from food and from extra calories your body stores. |
| Non-HDL Cholesterol | Total cholesterol minus HDL. Sums up all the bad particles in one number. Target is your LDL target plus 30. |
| ApoB (Apolipoprotein B) | A protein on every bad-cholesterol particle. Counts the particles directly. Newer, more precise risk marker. |
| Lp(a) | Lipoprotein little-a. An inherited form of bad cholesterol. Checked once in a lifetime. About 1 in 5 people carry high levels. |
| Familial Hypercholesterolemia (FH) | An inherited cause of very high LDL (often above 190 mg/dL). Runs in families. Needs early, aggressive treatment. |
| ASCVD | Atherosclerotic cardiovascular disease — heart attack, stroke, or blocked-artery disease anywhere in the body. |
| Statin | The most-used cholesterol medicine. Lowers LDL by 30 to 50 percent and cuts heart attack and stroke risk. |
| Plaque | A mix of cholesterol, calcium, and other cells that builds up inside artery walls and narrows the artery. |
Three things to remember about cholesterol:
1. LDL = BAD (carries cholesterol INTO artery walls). Lower is better.
2. HDL = GOOD (carries cholesterol AWAY). Higher is better.
3. Your LDL target depends on your overall risk — not just the number itself. See the ladder.

What Is Cholesterol?
- Cholesterol is a waxy substance your body needs. It helps build cell walls, make hormones, and produce bile that digests fat. Without any cholesterol, the body would not work.
- Most of your cholesterol is made by the liver. Only about 20 percent comes from the food you eat. That is why diet alone is often not enough to bring high numbers down.
- Cholesterol travels through the blood inside tiny packages called lipoproteins. The two main kinds are LDL and HDL. They do opposite jobs.
- LDL (low-density) is the BAD one. It carries cholesterol from the liver INTO the artery walls. Over years, this builds plaque and narrows arteries.
- HDL (high-density) is the GOOD one. It carries cholesterol AWAY from the artery walls and back to the liver to be cleared.
- Triglycerides are another blood fat. They come from food and from extra calories your body stores. Very high triglycerides can inflame the pancreas — a separate problem from plaque.
- A lipid panel is the blood test that measures all of these. Most adults should have a first lipid panel by age 20, then every 4 to 6 years — sooner and more often if you have risk factors.
- You can have very high cholesterol and feel completely fine. There are no symptoms until plaque is already large enough to cause a heart attack, stroke, or leg pain. The blood test is the only way to know.
Fasting or non-fasting?
For routine screening, a non-fasting lipid panel is FINE — the LDL and HDL numbers are accurate either way. If your triglycerides come back high on a non-fasting test, your team may repeat the panel after a 9 to 12 hour fast to be sure. Fasting is usually needed if triglycerides are very high or if specific advanced tests are ordered.
For routine screening, a non-fasting lipid panel is FINE — the LDL and HDL numbers are accurate either way. If your triglycerides come back high on a non-fasting test, your team may repeat the panel after a 9 to 12 hour fast to be sure. Fasting is usually needed if triglycerides are very high or if specific advanced tests are ordered.
Why It Matters
- High LDL is one of the strongest causes of heart attack and stroke. Lowering LDL has been shown — in dozens of large trials — to prevent heart attacks, strokes, and cardiovascular deaths.
- The benefit is dose-dependent: each 40 mg/dL drop in LDL reduces major heart events by about 20 to 25 percent. Lower is better, and the lower you go, the more events you prevent.
- The damage from high LDL adds up SLOWLY over decades. The earlier you bring LDL down, the more years of protected artery you get. This is why screening starts at age 20.
- Your LDL target depends on your overall heart risk — not just the number itself. A 35-year-old with no risk factors and an LDL of 120 is in a different situation than a 65-year-old after a heart attack with the same LDL.
- Cholesterol works WITH the other risk factors: high blood pressure, smoking, diabetes, and family history. Treating cholesterol does not let you ignore the others.
- Lp(a) is an inherited form of bad cholesterol that diet and exercise cannot change. About 1 in 5 people carry high levels. If your Lp(a) is high, your team will treat all your OTHER risk factors more aggressively.
Lp(a): The Inherited Risk You Need to Check Once
- Lp(a) is a special kind of bad-cholesterol particle. The level is set by your genes — diet and exercise barely change it.
- About 1 in 5 adults worldwide carry high Lp(a) (above 50 mg/dL or 125 nmol/L). It runs in families.
- High Lp(a) raises lifelong risk of heart attack, stroke, and aortic-valve calcification — even when LDL looks fine.
- Check Lp(a) ONCE in your lifetime. The number stays stable. Insurance usually covers a one-time test.
- There is no Lp(a)-specific approved drug yet (several are in trials). If your Lp(a) is high, we treat all your OTHER risk factors more aggressively — lower LDL target, lower BP target, no smoking.
- First-degree relatives (parents, siblings, children) of anyone with high Lp(a) should also be tested.

Risk Factors
Knowing your personal risks helps your care team take extra precautions.
| Risk Factor | Why It Increases Risk |
|---|---|
| Family history of high cholesterol or early heart disease | Familial hypercholesterolemia (FH) raises LDL above 190 from birth. Heart attack in a parent or sibling before 55 (men) / 65 (women) doubles your risk. |
| Diet high in saturated fat | Butter, fatty meat, full-fat cheese, lard, palm and coconut oil raise LDL. Trans fat (still in some packaged baked goods) is worse — avoid it completely. |
| Overweight or obesity | Extra body fat lowers HDL and raises LDL and triglycerides. Losing 5 to 10 percent of body weight improves all three. |
| Sedentary lifestyle | Lack of regular activity lowers HDL and raises triglycerides. 150 minutes a week of moderate exercise helps. |
| Smoking and vaping | Lowers HDL, damages artery walls, and makes LDL more harmful. Quitting raises HDL within weeks. |
| Type 2 diabetes and prediabetes | Drives high triglycerides, low HDL, and small dense LDL particles — the worst pattern for the arteries. |
| Underactive thyroid (hypothyroidism) | Raises LDL even on a perfect diet. A simple TSH blood test catches it; treating the thyroid often fixes the cholesterol. |
| Some medicines | Steroids, some HIV medicines, certain birth-control pills, and a few mental-health medicines can raise cholesterol. Ask your doctor about your list. |
| Inherited Lp(a) | About 1 in 5 people carry levels above 50 mg/dL. Diet and exercise do not change Lp(a). Check it ONCE in your lifetime. |
Treatment Options
Shown in English for your safety — this section is not automatically translated. Confirm with your doctor or call the office.
- Step 1 — Heart-healthy eating. The Mediterranean and DASH patterns lower LDL by about 10 percent and triglycerides by 15 to 20 percent. See our companion guide go.riasalimd.com/heart-healthy-eating-guide.
- Step 2 — Soluble fiber. Oats, beans, lentils, apples, berries, and psyllium (Metamucil) lower LDL by another 5 to 10 percent. Target 10 to 25 grams of soluble fiber per day.
- Step 3 — Move your body. 150 minutes per week of moderate exercise (brisk walking) lowers LDL by about 5 percent and raises HDL. Adds independent protection beyond the number.
- Step 4 — Weight loss if needed. Losing 10 pounds can drop triglycerides by 25 percent or more. Slow, steady loss is far better than a crash diet.
- Step 5 — Stop smoking. Raises HDL, drops LDL, and cuts heart-attack risk by half within 1 to 2 years. The single highest-yield change for any smoker.
- Step 6 — Statin therapy when LDL is still above your target after lifestyle, or when you are higher risk from the start. Statins lower LDL by 30 to 50 percent and cut heart attack and stroke risk by 25 to 35 percent. See go.riasalimd.com/statins-guide.
- Step 7 — Ezetimibe (Zetia) is added when a statin alone does not reach goal. Lowers LDL another 15 to 25 percent. Pill-form, well tolerated. See go.riasalimd.com/ezetimibe-guide.
- Step 8 — PCSK9 inhibitors (Repatha, Praluent) are powerful injectable medicines added for very-high-risk patients or familial hypercholesterolemia. Lower LDL another 50 to 60 percent. See go.riasalimd.com/pcsk9-guide.
- Step 9 — Bempedoic acid (Nexletol) is a newer non-statin pill, useful for statin-intolerant patients. Lowers LDL by about 20 percent. See go.riasalimd.com/bempedoic-guide.
- Step 10 — Check Lp(a) once. If high, there is no Lp(a)-specific approved drug yet — but knowing the number changes how aggressively we treat everything else. See go.riasalimd.com/lpa-guide.
Cholesterol-lowering medicines at a glance
| Drug class | How much LDL drops | Form / dosing | Common side effects |
|---|---|---|---|
| Statin (atorvastatin, rosuvastatin, simvastatin) | 30 to 50% (moderate intensity) 50% or more (high intensity) | Pill, once daily, usually at night | Muscle aches (5-10%), mild liver-enzyme rise, small rise in blood sugar |
| Ezetimibe (Zetia) | 15 to 25% added to a statin | Pill, once daily | Very few. Mild diarrhea or stomach upset |
| PCSK9 inhibitor (Repatha, Praluent) | 50 to 60% added to a statin | Injection every 2 weeks or monthly | Injection-site soreness, mild cold-like symptoms |
| Bempedoic acid (Nexletol) | About 20% added to a statin (or alone if statin-intolerant) | Pill, once daily | Small rise in uric acid (gout risk), tendon issues (rare) |
| Inclisiran (Leqvio) | 50% added to a statin | Injection twice a year | Injection-site soreness; convenience is the main benefit |
If you struggle with statin side effects.
Up to 1 in 10 patients have muscle aches on a statin. The good news: most can take SOME statin after switching brand, lowering the dose, or trying every-other-day dosing. If statins truly do not work, ezetimibe + bempedoic acid + PCSK9 inhibitor can replace most of the lost LDL reduction. See our Statin-Associated Muscle Symptoms guide: go.riasalimd.com/sams-guide.

Comfort Measures at Home (No Medication Needed)
These simple steps support healing and ease symptoms. Use them alongside any medication your doctor prescribes.
- Eat MORE plants. Half your plate vegetables and fruit. Beans and lentils 3 to 4 times a week. Fish 2 times a week.
- Choose WHOLE grains. Oats for breakfast, brown rice or quinoa for dinner, whole-wheat bread for sandwiches. Cut white bread and white pasta.
- Swap butter and lard for extra-virgin olive oil. Use it for cooking AND salads. A small handful of unsalted walnuts or almonds counts as healthy fat too.
- Add 10 to 25 grams of SOLUBLE fiber per day. Oats, beans, lentils, apples, oranges, berries, brussels sprouts. A packet of psyllium (Metamucil) is an easy add for many patients.
- Limit red meat to once a week. Skip processed meats (bacon, sausage, hot dogs, deli meats) — they raise LDL and blood pressure at the same time.
- Drink water as your default. Skip sugary drinks and fruit juice — they raise triglycerides quickly.
- Move your body 150 minutes a week. Brisk walking counts. Two short sessions of strength training per week add a boost.
- Sleep 7 to 8 hours per night. Poor sleep raises LDL, triglycerides, and blood pressure.
- If you smoke, ask us about quit support. Patches, gum, and prescription help all work. We can refer you.
Risks, Benefits, and Alternatives
Shown in English for your safety — this section is not automatically translated. Confirm with your doctor or call the office.
Every choice has trade-offs. Use this table to start the shared decision conversation with your care team.
| Option | Risks | Benefits | Alternatives |
|---|---|---|---|
| Lifestyle change alone | May not be enough if LDL is genetically high or your risk is already high. Slow to work — 8 to 12 weeks to see numbers shift. | Lowers LDL up to 15 percent, triglycerides 20 to 30 percent. Also lowers BP, blood sugar, and weight at the same time. | Adding a statin if numbers do not reach goal. Diet + medicine work BETTER together than either alone. |
| Statin (moderate or high intensity) | Muscle aches in 5 to 10 percent. Small rise in liver enzymes (rarely matters). Small rise in blood sugar in pre-diabetics. See our Statin-Associated Muscle Symptoms guide. | Lowers LDL 30 to 50 percent. Cuts heart attack and stroke risk by about 25 to 35 percent. Strongest cardiovascular benefit of any cholesterol pill. | Lower dose, every-other-day, or different statin if side effects. Ezetimibe or bempedoic acid if truly statin-intolerant. |
| Ezetimibe added to statin | Very few side effects. Costs more than generic statin alone. Modest LDL drop on top of statin. | Lowers LDL another 15 to 25 percent. Cuts heart events in post-heart-attack patients (IMPROVE-IT trial). | Higher statin dose first. PCSK9 inhibitor if very-high-risk and not at goal. |
| PCSK9 inhibitor (injection) | Injection every 2 weeks (or monthly). Expensive — usually requires prior authorization. Injection-site soreness is the most common side effect. | Lowers LDL by 50 to 60 percent ON TOP of statin. Cuts heart events further in high-risk patients (FOURIER, ODYSSEY). | Inclisiran (twice-yearly injection). Bempedoic acid. Higher statin dose plus ezetimibe. |
| Doing nothing | LDL keeps building plaque silently for years. First sign may be a heart attack, stroke, or sudden cardiac death. | No cost or side effects today. | Lifestyle change alone is the gentlest active option. Even small steps add up. |
Common Misconceptions
| Myth | Reality |
|---|---|
| "I feel fine, so my cholesterol must be OK." | High cholesterol has NO symptoms until it causes a heart attack, stroke, or leg-artery blockage. The blood test is the only way to know. Many patients are shocked by their first lipid panel. |
| "HDL is always good, so more is always better." | Most of the time, yes. But Lp(a) is an HDL-LIKE particle that is BAD — it raises heart and stroke risk. And very high HDL (over 80) has not been shown to help further. |
| "If I just eat right, I do not need medicine." | For some people, lifestyle is enough. For most with high LDL — especially familial cases or those with diabetes or ASCVD — diet alone does not get close to the target. Diet and statins WORK TOGETHER. |
| "Statins are dangerous — I will not take them." | Statins are among the most-studied medicines in history. Muscle aches happen in 5 to 10 percent and usually resolve by switching statins. Liver problems are rare. The proven benefit (fewer heart attacks and strokes) is far bigger than the small risk. |
| "Eggs and shrimp are full of cholesterol — I should avoid them." | Saturated fat in butter and fatty meat raises LDL much more than cholesterol in food. For most adults, 1 egg a day is fine — even with high LDL. |
| "Once my number is good, I can stop the statin." | Stopping the statin lets LDL climb right back up within weeks. The benefit (fewer heart attacks) only lasts as long as the LDL stays down. |
| "Coconut oil is plant-based, so it is heart-healthy." | Coconut oil is over 80 percent saturated fat — more than butter. It raises LDL. Use olive oil instead. |
| "My family all had high cholesterol and lived fine." | Familial hypercholesterolemia raises lifelong risk a LOT. Surviving family members often had unrecognized events. If a parent or sibling had a heart attack before 55 (men) or 65 (women), get checked early. |
Possible Complications
Knowing what can go wrong helps you spot problems early. Most complications are uncommon, especially with treatment.
| Where / What | What Can Happen |
|---|---|
| Heart attack | LDL plaque in a heart artery can crack open and form a clot that blocks blood flow. The most common cause of death in high-cholesterol patients. |
| Stroke | Plaque in the carotid (neck) and brain arteries can break off or block flow, causing a stroke. Same disease as a heart attack, different location. |
| Peripheral artery disease (PAD) | Plaque in the leg arteries causes pain when walking (claudication), wounds that will not heal, and — if untreated — limb loss. |
| Aortic plaque and aneurysm | Cholesterol plaque can weaken the wall of the aorta — the body's main artery — and lead to ballooning (aneurysm) or tearing (dissection). |
| Pancreatitis | Triglycerides over 500 mg/dL — and especially over 1,000 — can trigger sudden, severe inflammation of the pancreas. A medical emergency. |
| Tendon and skin deposits | In familial hypercholesterolemia, cholesterol deposits show up as yellow bumps on tendons (xanthomas) or around the eyes (xanthelasma). Treat the LDL aggressively. |
Triglycerides: The Other Blood Fat
- Triglycerides are a different blood fat from cholesterol. They come from the fat and extra calories you eat — especially sugar, alcohol, and refined carbs.
- Normal is under 150 mg/dL. Borderline 150 to 199. High 200 to 499. Very high 500 or above.
- Most LDL medicines (statins, ezetimibe, PCSK9) also lower triglycerides a little — but not enough if they are very high.
- Very high triglycerides (over 500) can inflame the pancreas. Over 1,000 is a medical emergency.
- First-line treatment is lifestyle: cut sugar and alcohol, lose weight, exercise. Weight loss of 5 to 10 percent can drop triglycerides by 30 percent.
- If lifestyle is not enough, prescription omega-3 (Vascepa or Lovaza), fibrates (fenofibrate), or niacin may be added. Vascepa also cuts heart-event risk in high-risk patients (REDUCE-IT trial).
- Recheck triglycerides 8 to 12 weeks after any major diet change or new medicine.
Familial Hypercholesterolemia (FH): When LDL Is Inherited
- FH is an inherited cause of very high LDL — usually above 190 mg/dL — present from birth.
- About 1 in 250 people have it. Often missed for decades until a young heart attack happens in the family.
- Without treatment, heart attacks often start in the 30s and 40s for men, 40s and 50s for women.
- Clues: LDL above 190 in adults (or above 160 in children); yellow tendon bumps (xanthomas) on the Achilles or hands; a ring around the cornea before age 45; heart attack in a parent or sibling before 55 (men) / 65 (women).
- Treatment is aggressive and lifelong: high-intensity statin from age 8 to 10, often PLUS ezetimibe, often PLUS a PCSK9 inhibitor. The target is LDL under 70 (or under 55 if heart disease already present).
- All first-degree relatives (parents, siblings, children) should be screened — this is called cascade screening.
Public health note from Dr. Ali. Cholesterol is one of the few heart-disease risk factors we can measure cheaply, change effectively, and prove makes a difference. Every 40 mg/dL drop in LDL — by any means — cuts major heart events by about 20 to 25 percent. The longer you spend at a lower LDL, the more years of protected artery you get. The single biggest gap in care is that many high-risk patients are not on enough medicine to reach their target. Ask: "What is my LDL target, and am I there?"
Points to Know
Shown in English for your safety — this section is not automatically translated. Confirm with your doctor or call the office.
If you remember nothing else, remember these key points.
- Cholesterol has no symptoms — the lipid panel is the only way to know your numbers.
- LDL is the BAD one. Lower is better. Your target depends on your risk tier (see the ladder).
- HDL is the GOOD one. Aim for men at least 40, women at least 50 mg/dL.
- Triglycerides under 150. Over 500 = risk of pancreatitis.
- Get a lipid panel by age 20, then every 4 to 6 years. Sooner and more often if you have risk factors.
- Lp(a) is an inherited risk — check it ONCE in a lifetime. About 1 in 5 people carry high levels.
- Lifestyle is step 1. Mediterranean / DASH eating, exercise, weight loss, and stop smoking lower LDL up to 15 percent.
- Statins lower LDL 30 to 50 percent and cut heart attack and stroke risk by a quarter to a third. They are safe for almost everyone who needs them.
- If a statin alone is not enough, ezetimibe, PCSK9 inhibitors, bempedoic acid, and inclisiran add big extra LDL reduction.
- Diet and medicine WORK TOGETHER — not one or the other. Each one adds to the other.
When to Call Us — and When to Call 911
Shown in English for your safety — this section is not automatically translated. Confirm with your doctor or call the office.
If you are not sure, call. We would rather hear from you twice than miss a real problem.
- Call 911 for sudden chest pressure or pain, shortness of breath, weakness on one side, trouble talking, sudden bad headache, or fainting. These are heart-attack and stroke warning signs.
- Call our office (727-943-5200) if you have new muscle aches, weakness, or dark urine after starting a statin — we may need to check a blood test.
- Call us if your last lipid panel was more than 1 year ago and you take cholesterol medicine. We aim to recheck 8 to 12 weeks after any dose change and once a year after that.
- Call us if you have a strong family history of early heart attack or very high cholesterol — your first lipid panel may need to happen earlier than age 20.
- Call us if your triglycerides are above 500 mg/dL. Very high triglycerides can inflame the pancreas — a separate emergency from heart disease.
- Call us to schedule your one-time Lp(a) check if you have never had it tested. Knowing the number changes how we treat everything else.
- Ask us about a coronary calcium scan (CAC) if you are at borderline risk and unsure about starting a statin. See go.riasalimd.com/cac-guide.
