Picture this: You’re at your annual checkup. Your doctor listens to your heart, checks your blood pressure, maybe runs a basic cholesterol test. “Everything looks fine,” they say. You leave feeling reassured.
But here’s what many South Asians don’t realize:
For us, “standard” heart checkups often aren’t enough.
Heart disease strikes South Asians 10–15 years earlier than other groups. Many of us — Indians, Pakistanis, Bangladeshis, Sri Lankans, Nepalis — develop heart problems in our 30s or 40s. The scary part?
You can feel completely fine while dangerous changes are happening inside your arteries.
That’s why these 8 advanced heart tests are life-saving.
They catch what regular checkups miss.
They give you time to act — before it’s too late.
What it is: A CT scan that checks for calcium buildup in your heart arteries.
Why it matters: South Asians often have more calcium buildup even with “normal” cholesterol.
When to ask for it: Age 40+ (or 35+ if you have diabetes or family history)
Did you know?
A score above 100 means your risk of heart attack is as high as someone who’s already had one!
What it is: A blood test that counts the number of “bad” cholesterol particles.
Why it matters: Total cholesterol may look normal, but ApoB reveals true risk — especially in South Asians.
When to ask for it: Alongside your next cholesterol panel.
Did you know?
Two people can have the same cholesterol level but very different ApoB — and risk.
What it is: A genetic cholesterol test — most people only need it once.
Why it matters: 1 in 4 South Asians have high Lp(a), compared to 1 in 10 in other populations.
When to ask for it: Once in your life (it doesn’t change much)
Did you know?
If you have high Lp(a), your children have a 50% chance of having it too.
What it is: A blood test for an amino acid linked to artery damage.
Why it matters: Vegetarian diets common in South Asians can lead to low B12 → high homocysteine.
When to ask for it: Especially if you’re vegetarian or have early family history of heart disease.
Did you know?
B vitamins like B12, B6, and folate can often bring high levels down naturally.
What it is: Blood tests for long-term blood sugar and early signs of diabetes.
Why it matters: South Asians have the world’s highest diabetes rates — and many are undiagnosed.
When to ask for it: Age 25+, or earlier if overweight or with family history.
Did you know?
Many South Asians are “thin on the outside, fat on the inside” — normal weight but high risk.
What it is: LDL (“bad”), HDL (“good”), and triglycerides.
Why it matters: Our pattern is often low HDL and high triglycerides — a dangerous combo.
When to ask for it: Starting at age 20, then every 4–6 years (more often if abnormal).
Did you know?
HDL under 40 (men) or 50 (women) is a serious warning sign.
What it is: The force of blood against your artery walls.
Why it matters: South Asians often develop high BP young — and don’t know it.
When to ask for it: Every visit to any doctor.
Did you know?
“High-normal” BP (130–139/80–89) still raises your heart disease risk.
What it is: A blood test that shows inflammation levels in your body.
Why it matters: High CRP doubles your heart attack risk — and South Asians often have more inflammation.
When to ask for it: If you have risk factors or family history.
Did you know?
Walking, turmeric, yoga, and managing stress can naturally reduce CRP.
These tests aren’t just numbers — they’re your early warning system.
Many South Asians think heart disease is just “in the family.” But here’s the truth:
Genetics load the gun. Lifestyle pulls the trigger.
These tests help you see if the gun is loaded — so you can make better choices before it fires.
Don’t wait for symptoms.
Don’t assume you’re too young.
Don’t think a “normal” checkup is enough.
Ask your doctor about these 8 tests.
Share this list with your family.
Take charge of your health — before it’s urgent.
Because knowing your risk isn’t scary.
Not knowing is.
Your calcium score tells you how much plaque has built up in your heart arteries:
Score of 0: No detectable calcium — excellent news [1]
Score of 1-99: Mild plaque present
While this is “low risk” for most people, South Asians should take even low scores seriously. Research shows we develop heart disease at lower calcium levels than other populations [2].
Score of 100-399: Moderate plaque buildup
You have coronary artery disease, but you can still prevent serious problems [3].
Score of 400+: Extensive plaque present
You’re at higher risk for heart events, but aggressive treatment can significantly reduce this risk [4].
Remember: Your score shows accumulated plaque, not current danger. A person with a score of 500 who’s being treated properly may be safer than someone with a score of 100 who’s doing nothing about it.
If your score is above 100 (or above 75 with risk factors), ask for a referral to a cardiologist. They specialize in cases like yours and can create a comprehensive treatment plan [5].
Your doctor may recommend:
Coronary CT Angiogram (CTA): Shows if plaques are blocking blood flow [6] 🔗 Learn more about CT Angiogram
Stress Test: Checks how your heart works during exercise
Advanced Lipid Testing: Including ApoB and Lp(a) to understand your cholesterol particles better [7] 🔗 What to do if ApoB is high
Blood pressure medicine — even if your readings are “normal”
Why? It helps reduce artery stress when combined with plaque
Low-dose aspirin (depending on your overall risk)
PCSK9 inhibitors or other advanced cholesterol drugs if needed
Research shows these dietary changes can slow plaque progression:
Aim for 35+ grams daily
Sources: vegetables, lentils, whole grains [10]
Less ghee, butter, fatty meats
Switch to mustard oil or olive oil
No vanaspati, margarine, deep-fried foods
Check labels for “partially hydrogenated oils”
Found in nuts, seeds, legumes [11]
Consider fortified foods
Pro tip: The Portfolio Diet has been shown to lower LDL by 30% — as much as some medications! [12]
The European Society of Cardiology recommends:
150 minutes of moderate exercise weekly (brisk walking)
75 minutes of vigorous exercise (jogging, swimming)
Start small: Even 10-minute walks after meals help. South Asian tradition got this right!
Note: Always discuss supplements with your doctor, especially if you’re on medications.
Chronic inflammation accelerates plaque buildup. Lower it by:
Get 7-8 hours of quality sleep [17]
Treat sleep apnea if present
Important: Your calcium score won’t decrease — calcium in plaques is permanent. But you can:
Prevent new plaque formation
Stabilize existing plaques
Dramatically reduce your heart attack risk [20]
Expect regular monitoring:
Cholesterol checks every 3-6 months initially
Monthly blood pressure monitoring
Repeat calcium scan in 3-5 years
Annual stress tests if recommended
Regular check-ins with your cardiologist
Look for these improvements:
Better cholesterol numbers (especially ApoB)
Lower blood pressure
Reduced inflammation (CRP levels)
Better blood sugar control
Increased exercise capacity
Improved energy levels
Look for these improvements:
Quick Questions
Q: Can my calcium score go down?
A: No, the calcium is permanent. But you can stop it from increasing and reduce your risk dramatically.
Q: How often should I repeat the test?
A: Usually every 3-5 years, or as your doctor recommends. More frequent testing doesn’t help.
Q: Should my spouse get tested?
A: If they’re over 40 (or 35 with risk factors), yes. Heart disease often affects both partners due to shared lifestyle.
Key Takeaways
**Share this with your parents, siblings, or children.** Heart risk runs in families — but so does prevention. Knowledge is power, and your family needs this information too.
The Bottom Line
A high calcium score is like getting a weather warning before a storm. You can’t stop the weather, but you can prepare your house, stock supplies, and stay safe.
Similarly, you can’t remove calcium from your arteries, but you can protect yourself from heart attacks and live a long, healthy life.
Work closely with your healthcare team
Take your medications as prescribed
Make the lifestyle changes that matter
Most importantly, don’t lose hope — you’ve caught this early enough to make a real difference

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.
