Preventive Cardiology10 min readBy Dr. Sanjeev Gera, MD, DNB (Cardiology)

Every week, someone hands me a lipid report with every value printed in reassuring black ink, nothing flagged in red, and says, “My cholesterol is normal, so why did I have a heart attack?”

It is a fair question, and the honest answer is uncomfortable: the “normal range” on your lab report was never designed to protect your heart. For many Indians, especially those with diabetes, a family history or an existing heart problem, a “normal” LDL cholesterol can still be far too high. And one of the most powerful inherited risk factors, lipoprotein(a), is not even part of a routine lipid profile.

In this article, I will walk you through how to read your cholesterol report the way a cardiologist does, explain the targets that actually matter, and clear up the myths about statins that stop so many people from taking a medicine that could save their life.

Anil (name changed), a 39-year-old non-smoking bank officer from Greater Noida, came to the emergency room with a heart attack. His LDL was 118 mg/dL, inside the lab’s “normal” range. His father had a bypass at 52. When we tested his lipoprotein(a), it was more than three times the risk threshold. Nobody had ever checked it.

Key Takeaways

  • Lab “reference ranges” describe the general population, not what is safe for your heart. Your ideal LDL depends on your personal risk.
  • For people who already have heart disease or a stent, cardiology guidelines advise LDL below 55 mg/dL, and Indian experts recommend below 50 mg/dL for very high-risk patients.
  • Lipoprotein(a), or Lp(a), is largely genetic and is not affected much by diet. Experts now recommend testing it at least once in a lifetime.
  • Statins are among the most studied medicines in the world. Serious side effects are uncommon, and most people tolerate them well.
  • Indians develop heart disease about a decade earlier than Western populations, so starting prevention early matters.

Why “Normal” Cholesterol Can Still Be Dangerous

The reference range printed on a lab report is usually based on what is common in the population, or on generic thresholds for low-risk people. But in a country where heart disease is common, “common” is not the same as “healthy”.

Cardiologists do not judge cholesterol in isolation. We first ask: how high is this person’s overall risk of a heart attack or stroke? Then we set a target. The higher your risk, the lower your LDL cholesterol needs to be. An LDL of 110 mg/dL might be acceptable for a healthy 30-year-old with no risk factors, but it is clearly too high for a 50-year-old with diabetes and a stent.

There is no single “normal” cholesterol. There is only the right cholesterol for your heart.

The principle behind every modern cholesterol guideline

Reading Your Lipid Profile Like a Cardiologist

The main culprit

LDL Cholesterol

The “bad” cholesterol that enters the artery wall and builds plaque. This is the number most treatment targets are based on.

Often misunderstood

HDL Cholesterol

Low HDL is a risk marker, but medicines that raise HDL have not reduced heart attacks. Focus on lowering LDL rather than chasing HDL.

Common in Indians

Triglycerides

Often high with belly fat, diabetes, refined carbohydrates and alcohol. They respond well to lifestyle change.

The total burden

Non-HDL Cholesterol

Total cholesterol minus HDL. It captures all the artery-clogging particles and is especially useful when triglycerides are high.

What LDL target should you aim for?

The table below summarises the commonly used targets from European cardiology guidelines and the Lipid Association of India. Your cardiologist will place you in the right category after assessing your full history.

Your risk categoryTypical examplesLDL target
Low to moderate riskYoung adults with no or few risk factorsBelow 100 mg/dL
High riskDiabetes without organ damage, multiple risk factors, very high single risk factorBelow 70 mg/dL
Very high riskPrevious heart attack, stent, bypass or stroke; diabetes with organ damage; significant plaque on imagingBelow 55 mg/dL (ESC) / below 50 mg/dL (LAI)
Extreme riskRepeat events, or heart disease with additional high-risk features such as diabetes or very high Lp(a)Around 30 mg/dL or lower, as advised

Lipoprotein(a): The Hidden Risk Factor Most People Have Never Tested

Lipoprotein(a), pronounced “L-P-little-a”, is a cholesterol-carrying particle similar to LDL, but with an extra protein attached that makes it stickier and more likely to promote clotting and inflammation. High Lp(a) increases the risk of heart attack, stroke and narrowing of the aortic valve.

Here is what makes it different from other cholesterol numbers:

  • It is mostly inherited. Your level is largely set by your genes, and diet and exercise barely change it.
  • It is not in a standard lipid profile. It needs to be specifically requested.
  • One test is often enough. Because it stays fairly stable through life, both European and Indian experts recommend measuring it at least once in adulthood.
  • Levels above about 50 mg/dL (roughly 105–125 nmol/L) are generally considered to increase risk.

Elevated Lp(a) appears to be common in Indians, and it may help explain why some people with otherwise “perfect” habits develop early heart disease. While specific Lp(a)-lowering medicines are still being tested in large trials, knowing your level is valuable today: it tells us to be more aggressive with LDL lowering, blood pressure control and other risk factors.

Should you ask for an Lp(a) test?

  • You or a close family member had a heart attack, stent, bypass or stroke at a young age
  • You have heart disease despite few traditional risk factors
  • Your LDL stays stubbornly high, or you have a family history of high cholesterol
  • You have narrowing of the aortic valve (aortic stenosis)
Stages of cholesterol plaque buildup inside a coronary artery from healthy to severely narrowed
Plaque builds silently over years. Lowering LDL early slows, and can partly reverse, this process.

Why Indians Need to Start Earlier

South Asians tend to develop coronary artery disease about ten years earlier than people of European descent, and often with more diffuse, multi-vessel blockages. Several factors combine: a higher tendency towards insulin resistance and diabetes, abdominal fat even at a “normal” body weight, higher triglycerides, smaller and denser LDL particles, higher Lp(a) in many people, and rapidly changing lifestyles with long sitting hours and processed food.

The practical message is simple: get your first lipid profile in your twenties, know your Lp(a), and do not wait for symptoms before taking cholesterol seriously. If you are unsure which symptoms matter, read our guide on the warning signs your heart may be giving you.

Statins: Separating Myth From Evidence

Statins lower LDL cholesterol and stabilise existing plaque. They have been studied in hundreds of thousands of people over more than three decades and consistently reduce heart attacks, strokes and deaths in people at risk. Yet fear of side effects is one of the most common reasons patients stop them. Let us look at the common concerns honestly.

Myth“Statins damage the liver, so I should avoid them.”
FactA mild rise in liver enzymes can occur but is usually harmless. Serious liver injury is rare. Statins are even used safely in many people with fatty liver.
Myth“Statins always cause muscle pain.”
FactMuscle aches are reported, but in blinded trials most of these symptoms occur just as often with placebo. True statin muscle damage is uncommon, and switching dose or type usually solves genuine intolerance.
Myth“Once I start a statin, I’m stuck on it forever, so I won’t start.”
FactStatins work only while you take them. Long-term use is the point: like wearing a seatbelt, the protection lasts as long as you keep using it.
Myth“Statins cause diabetes, so they do more harm than good.”
FactStatins slightly increase the chance of diabetes being diagnosed, mainly in people already close to the threshold. For people at risk of heart disease, the reduction in heart attacks and strokes far outweighs this.
Myth“My cholesterol is now normal, so I can stop the tablet.”
FactYour cholesterol is normal because of the tablet. Stopping it lets LDL rise again within weeks. Never stop without discussing it with your cardiologist.

Beyond statins

If a statin alone does not bring LDL to target, or cannot be tolerated, there are effective add-ons: ezetimibe, a tablet that reduces cholesterol absorption; bempedoic acid; and injectable therapies such as PCSK9 inhibitors and inclisiran, which can lower LDL dramatically. Your cardiologist will choose based on your risk, response and budget.

What You Can Do Starting This Week

  • Know your numbers: LDL, non-HDL, triglycerides, HbA1c and, at least once, Lp(a).
  • Swap refined carbs and fried snacks for whole grains, dals, vegetables, nuts and seeds. Cut back on vanaspati, bakery items and deep-fried street food.
  • Move every day: aim for at least 150 minutes of brisk walking or equivalent activity each week, and break up long sitting hours.
  • Watch your waist, not just your weight. Abdominal fat is a strong risk marker in Indians.
  • Quit tobacco in every form, including gutka and hookah.
  • Take prescribed medicines consistently and repeat your lipid profile as advised to check you are at target.

What Happened to Anil

After a successful angioplasty, Anil was started on a high-intensity statin plus ezetimibe, bringing his LDL below 50 mg/dL within three months. His brother and sister were tested too; one of them also had high Lp(a) and has now started early prevention. Sometimes the most important outcome of one person’s heart attack is protecting the rest of the family.

Frequently Asked Questions

What is a normal LDL cholesterol level?

There is no single normal value. For low-risk adults, below 100 mg/dL is generally acceptable. For people with diabetes and other risk factors, below 70 mg/dL is advised, and for those with heart disease or a stent, below 55 mg/dL (or below 50 mg/dL as per Indian recommendations). Your cardiologist will define your personal target.

What is the Lp(a) test and who should take it?

Lipoprotein(a) is a mostly inherited cholesterol particle that raises the risk of heart attack and stroke. Experts recommend that adults check it at least once in their lifetime, and especially those with early heart disease in themselves or their family.

Can I lower my cholesterol without medicines?

Diet, exercise and weight loss can lower LDL modestly and improve triglycerides significantly. For people at low risk this may be enough. For those at high risk or with existing heart disease, lifestyle changes alone rarely reach the target, and medicines are usually needed.

Are statins safe to take long term?

Yes. Statins have been used by millions of people for decades. Most people tolerate them well, and serious side effects are uncommon. Any symptoms should be discussed with your doctor, who can adjust the dose or switch medicines.

Should I fast before a lipid profile test?

For most people, a non-fasting test is acceptable and gives reliable LDL and non-HDL values. Fasting may be advised if your triglycerides were previously very high. Follow your doctor’s or lab’s instructions.

At what age should I first check my cholesterol?

Most adults should have their first lipid profile in their twenties, and earlier if there is a family history of high cholesterol or early heart disease. Given the earlier onset of heart disease in Indians, early testing is especially worthwhile.
