South Asians are genetically more prone to store fat around their organs (not just under the skin), develop insulin resistance early, and experience heart disease at younger ages — even when their weight and cholesterol appear normal.
Not necessarily. Many South Asians have heart attacks despite normal cholesterol. Advanced tests like ApoB and Lipoprotein(a) are better at showing hidden risk.
ApoB measures the number of cholesterol particles that can clog your arteries. It’s a stronger predictor of heart disease than just LDL. Many South Asians with “normal” LDL still have high ApoB.
Yes. Many South Asians are TOFI — Thin Outside, Fat Inside. Even slim people can have dangerous fat around the heart, liver, and pancreas that raises their risk.
Not always. A typical South Asian vegetarian diet can still be high in fried snacks, sugar, and refined carbs. Protein and fiber are often too low.
It’s a quick, painless CT scan that shows plaque in your heart arteries. It’s especially helpful if you’re South Asian, over 40, or have a family history of early heart disease.
Even if you’re not overweight, a waist size over 35 inches (90 cm) in men or 31 inches (80 cm) in women increases heart attack risk significantly.
Yes — it can reduce belly fat, lower insulin levels, and improve heart health. Just be mindful of sugar in chai and be consistent with meal timing.
Take a 10-minute walk after dinner. It helps control blood sugar, reduces belly fat, and is a powerful habit — especially if done daily.
This is a very common question! Many people think they only need to see a doctor when they feel sick. But when it comes to heart disease, feeling healthy doesn’t always mean you are healthy. Here’s why:
Heart disease is often called a “silent killer” because it can develop for years without causing any symptoms you can feel. By the time you notice problems, significant damage may have already occurred.
Think about it this way:
Mrs. Patel, a 52-year-old who never smoked and walked daily, felt perfectly fine until she had a sudden heart attack. During her recovery, tests showed her arteries had been narrowing for years. “If only I had gotten tested earlier,” she said, “I could have made changes or taken medication to prevent this.”
Several important tests can detect heart issues before you feel any symptoms:
Calcium Score Test This simple CT scan looks for hardened calcium in your heart’s arteries. It can show plaque buildup years before you might have symptoms. A score of zero means very low risk, while higher scores indicate more plaque and higher risk.
ApoB Blood Test This test measures a protein that carries “bad” cholesterol in your blood. Research shows it may be more accurate than traditional cholesterol tests at predicting heart attack risk. Many people with “normal” cholesterol levels still have high ApoB, which puts them at risk.
Blood Pressure Check This basic test is easy but powerful. High blood pressure typically causes no symptoms until it leads to serious problems like heart attack or stroke.
Blood Sugar Test Diabetes and pre-diabetes increase heart disease risk significantly. Many people have elevated blood sugar for years without knowing it.
You should consider heart testing even if you feel fine if you:
Finding problems early gives you more options:
Having heart tests when you feel fine is like checking your car’s engine before a long trip, even though it seems to be running well. It’s about prevention, not just treatment.
Remember, the first symptom of heart disease can be the most serious one – a heart attack. Many people who had heart attacks say they felt completely normal the day before.
Your heart works 24/7 for your entire life without a break. Isn’t it worth checking in on it occasionally, even when everything seems fine?

Both LDL and ApoB are tests that check for heart risk in your blood, but they measure different things. Let’s explain this in simple terms.
LDL cholesterol is a number that shows how much “bad” cholesterol is in your blood.
ApoB shows how many “bad” particles are in your blood that can cause heart problems.
Think of it this way:
What’s more important for heart risk? It’s the number of trucks (ApoB), not just how much total cargo they carry (LDL).
Here’s why: Each “bad” particle in your blood (like LDL) has exactly one ApoB protein on it. So ApoB directly counts how many potentially harmful particles are traveling in your blood [1].
When many small trucks (particles) carry a little cholesterol each, they can squeeze into the walls of your heart’s blood vessels more easily than a few big trucks carrying lots of cholesterol.
Traditional LDL tests might miss this problem. You could have “normal” LDL but still have too many small trucks (high ApoB) causing damage [2].
Imagine two people:
Person 1: Has 5 large trucks, each carrying 100 kg of cargo
Person 2: Has 50 small trucks, each carrying 10 kg of cargo
The traditional LDL test would show the same result for both people (500 kg of cargo). But Person 2 has ten times more trucks (particles) that can damage blood vessels!
South Asians often have a pattern of small, dense LDL particles with high ApoB levels even when their regular LDL cholesterol looks normal [3]. This may be one reason why heart disease is more common in our community.
Consider asking for an ApoB test if:
For ApoB, lower is better:
LDL tells you how much cholesterol is in your blood. ApoB tells you how many particles are carrying that cholesterol. For heart health, knowing both gives you a more complete picture, but the number of particles (ApoB) is often more important than just the amount of cholesterol (LDL).

[2] Washington Post. (2024). “Why the ApoB cholesterol test is a better predictor than standard tests.”

“My cholesterol is normal, so I’m safe from heart problems, right?”
If you’ve ever asked this question after a checkup, you’re not alone. Getting that “normal” result feels like passing an important health exam. It’s reassuring to see those numbers in the healthy range.
But for many South Asians, normal cholesterol might not tell the whole story.
Many people with perfect cholesterol numbers still have heart attacks. In fact, studies show that about half of all people who have heart attacks have “normal” cholesterol levels.
This is especially important for South Asians to understand. Our community has higher rates of heart disease that often appears at younger ages than in other populations.
Vikram, a 48-year-old software engineer, had normal cholesterol at his yearly checkup. He ate vegetarian food, wasn’t overweight, and played cricket on weekends.
“I thought I was doing everything right,” he says. “My doctor always told me my cholesterol was perfect.”
Yet Vikram ended up in the emergency room with chest pain. Tests showed he had significant blockage in his heart arteries. How could this happen with normal cholesterol?
Traditional cholesterol tests measure:
While these are important, they don’t show the whole picture. Think of it like checking only the temperature outside without looking at whether it’s raining or windy.
Here are three important heart tests many South Asians have never heard of:
ApoB measures the number of potentially harmful particles in your blood, not just the amount of cholesterol they carry.
Simple explanation: Imagine your bloodstream as a highway. LDL cholesterol tells you how much cargo is being transported. ApoB tells you how many trucks are carrying that cargo. It turns out that having too many trucks (even small ones) can cause more traffic problems than a few big trucks.
Many South Asians have a pattern of many small, dense cholesterol particles that don’t show up as abnormal on traditional tests.
Lp(a) is largely determined by your genes. It’s like a special type of cholesterol particle that’s stickier and more likely to cause blockages.
Simple explanation: If cholesterol is like fat floating in your bloodstream, Lp(a) is like sticky fat that more easily attaches to your artery walls.
About 1 in 4 South Asians have high Lp(a) levels. It doesn’t show up on regular cholesterol tests, and doesn’t change much with diet or exercise.
This isn’t a blood test, but a special CT scan that looks for early buildup in heart arteries before you have any symptoms.
Simple explanation: While blood tests tell you about risk factors, a Calcium Score is like taking a photo of your heart arteries to see if buildup has already started.
“My cholesterol was always normal, so I thought I was different from my father,” she says. “But my doctor suggested these additional tests because of my South Asian background.”
Her ApoB and Lp(a) tests showed high levels that her regular cholesterol test missed. With this knowledge, she made targeted lifestyle changes and started appropriate medication.
“I’m grateful I found out before having a heart attack,” Priya says. “These tests might have saved my life.”
Research shows that South Asians often have:
These differences mean that normal cholesterol results may not be as reassuring for South Asians as they are for other groups.
A normal cholesterol test is good news. But for complete heart protection, especially for South Asians, these additional tests provide a more complete picture.
Knowledge is power. Understanding your true heart risk allows you to take the right steps for protection. After all, your heart works hard for you every day—it deserves the most complete care you can give it.
Have you had any of these advanced heart tests? Share your experience in the comments below!
Absolutely yes! Good doctors appreciate patients who take an active interest in their health. Remember, your doctor works for you, not the other way around. You have every right to ask questions about your health and request tests that might benefit you.
Many doctors may not routinely order newer tests like ApoB or Lp(a) because they follow standard guidelines. But these guidelines don’t always address the specific risks that South Asians face.
There are several reasons:
Here are some respectful ways to bring up these tests:
Ask them to help you understand why:
If you still feel your concerns aren’t being addressed:
A good doctor will appreciate your engagement with your health. Frame your request as collaboration, not challenging their judgment:
It’s perfectly fine to ask about costs before proceeding:
Some labs offer cash discounts, and knowing your risk factors might save you money and health problems in the long run.
Prevention is always better than treatment. Explain that you’re trying to be proactive:
While most primary care physicians can order these tests, some specialists might be more familiar with them:
If your primary doctor isn’t familiar with these tests, it’s okay to ask for a referral to a specialist.
Your health is too important to let awkwardness or politeness get in the way of getting the best care possible. A good doctor-patient relationship is a partnership, and that means open communication from both sides.

A cardiovascular risk calculator is a medical tool that estimates your chance of having a heart attack or stroke in the next 10 years.
Think of it as a personalized weather forecast for your heart health—it combines multiple factors about your health to predict future risk.
Risk calculators are built using data from large medical studies that follow thousands of people over many years.
Researchers track who develops heart disease and identify the common factors that increase risk.
These patterns are then turned into mathematical formulas that can predict individual risk.
Key Components:
Most calculators evaluate these core factors:
Risk Categories:
What Your Number Means: A 10% risk means that out of 100 people exactly like you, about 10 will have a heart attack in the next 10 years. It's a probability, not a certainty.
Most widely-used risk calculators were developed using predominantly white populations.
This creates significant problems for South Asians:
Just as weather forecasts are more accurate when they account for local geography and climate patterns,
heart disease risk assessment is more accurate when it accounts for population-specific health patterns.
A good risk calculator doesn't just give you a number—it helps you understand:
Risk assessment is most valuable when it guides action:
Modern risk calculators are becoming more sophisticated:
The future of cardiovascular risk assessment is moving toward truly personalized predictions that account for:
Remember These Important Points:
Bottom Line: A good cardiovascular risk calculator is a powerful tool for understanding and preventing heart disease,
but it works best when designed for your specific population and used alongside professional medical care.
