Your uncle Raj goes to see his doctor for his yearly checkup. The nurse wraps a cuff around his arm, it gets tight, then slowly releases. “Your blood pressure is 150 over 90,” she says. Uncle Raj nods but isn’t sure what this means for his health.
Blood pressure is the force of blood pushing against your artery walls as your heart pumps. Think of it like water pressure in your garden hose. When you squeeze the hose, pressure builds up. Your arteries are like that hose, and your heart is the pump.
The first number (systolic) measures pressure when your heart beats and pushes blood out. The second number (diastolic) measures pressure when your heart rests between beats. Both numbers matter for your health.
When blood pressure stays too high for too long, it’s like having that garden hose under constant high pressure – eventually, it can damage the hose. High blood pressure can damage your arteries, heart, brain, kidneys, and eyes.
Common Myth: “I feel fine, so my blood pressure must be normal.”
Truth: High blood pressure usually has no symptoms, which is why it’s called the “silent killer.”
Priya’s father had a heart attack at age 52. Her grandmother developed diabetes in her 40s. Priya wonders if her family is just unlucky, or if there’s something more going on.
South Asians have a significantly higher odds of premature ischemic heart disease (defined as men aged <55 years and women aged <65 years; OR: 1.77; 95% CI: 1.05-2.97) vs Europeans even after adjusting for demographic and traditional CV risk factors such as diabetes mellitus and hypertension. South Asians represent approximately one fourth of the world’s population, but they account for more than 50% of the global cardiovascular deaths.
In the INTERHEART study, the mean age of first myocardial infarction was 53 years in South Asia vs 62-63 years in China and Europe. This means South Asians get heart attacks about 10 years earlier than other groups.
Several factors make South Asians more vulnerable: genetic differences affect how our bodies process fats and sugars, higher rates of diabetes and insulin resistance, different fat distribution (more belly fat), and unique responses to blood pressure changes. Compared with Europeans, South Asians have higher SBP, diastolic BP and mean arterial pressure, and the association between BP and stroke is stronger.
Common Myth: “Heart disease only affects older people in our community.”
Truth: South Asians can develop serious heart problems 10-15 years earlier than other groups.
Ravi felt perfectly fine when he went for his annual physical. He exercises regularly, eats well, and has lots of energy. So he was shocked when his doctor told him his blood pressure was 160/95 – dangerously high.
High blood pressure earned the nickname “silent killer” because most people have no symptoms until serious damage has already occurred. Your body is remarkably good at adapting to slowly rising blood pressure, so you won’t feel the changes happening inside.
Why You Can’t Feel High Blood Pressure: Your blood vessels gradually adapt to higher pressure, your brain adjusts to the new “normal,” and symptoms only appear when organs are already damaged.
What’s Happening Inside When You Can’t Feel It: Your artery walls are thickening and becoming less flexible, your heart is working harder and may be enlarging, small blood vessels in your kidneys may be getting damaged, and your risk of blood clots is increasing.
By the time you feel symptoms, you may already have had a heart attack, stroke, kidney damage, or eye problems.
Common Myth: “If my blood pressure was really high, I would feel sick.”
Truth: Most people with high blood pressure feel completely normal until serious complications develop.
Amit’s blood pressure reading is 135/85. His doctor says it’s “borderline high” but Amit doesn’t understand if he should be worried or not. What do these numbers really mean?
The ESH recommends a threshold of >140/90 mm Hg (grade 1) for the diagnosis of hypertension, whereas the ACC/AHA guideline recommends a lower threshold of >130/80 mm Hg (stage 1).
Normal: Less than 120/80 mmHg
Elevated: 120-129 systolic and less than 80 diastolic
Stage 1 High: 130-139/80-89 mmHg
Stage 2 High: 140/90 mmHg or higher
Crisis: Higher than 180/120 mmHg
For South Asians, even “borderline” numbers matter more because of our higher baseline risk. In the U.K. Biobank, with every 20 mm Hg rise in systolic blood pressure, the risk of CV events increased by 33% among South Asians vs 12% among Europeans.
Common Myth: “130/80 is ‘almost normal’ so I don’t need to worry.”
Truth: For South Asians, even these “borderline” numbers significantly increase heart attack and stroke risk.
Neha is 28 and healthy. Her mother asks when she should start checking her blood pressure regularly. “I’m young and feel fine,” Neha says. “Can’t this wait until I’m older?”
The answer depends on your risk factors. South Asians should start earlier than other groups because we develop problems younger.
Age 18-25: Check every 2 years if you have
Age 18+ (Check Every Year):
Age 30+ (Check Every 6 Months):
Age 40+ (Check Every 3-4 Months):
We advise considering high-CVD-risk race/ethnicity (e.g. South Asian), family history of premature onset atherosclerotic CVD (CVD event in males aged <55 years and/or females <65 years), socio-economic deprivation, inflammatory conditions as important risk factors.
Common Myth: “I’m too young to worry about blood pressure.”
Truth: South Asians can develop high blood pressure and heart disease in their 30s and 40s.
Deepak’s doctor told him his blood pressure is 145/90 and he needs to make lifestyle changes before considering medication. Deepak wants to try natural methods first but doesn’t know where to start.
The DASH Diet – Modified for South Asian Tastes:
Eat More Of:
Eat Less Of:
Exercise That Works: 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity aerobic exercise per week is recommended to be supplemented with low- or moderate-intensity dynamic or isometric resistance training 2× to 3× per week.
Cardio Options: Brisk walking, dancing to Bollywood music, swimming, cycling, climbing stairs
Strength Training: Push-ups, squats, resistance bands, light weights 2-3 times per week
Lifestyle Changes:
Potassium Power: Potassium helps balance sodium’s effects. Good sources include bananas, potatoes, spinach, yogurt, and coconut water.
Common Myth: “I need to completely give up all my favorite South Asian foods.”
Truth: You can modify traditional recipes to be heart-healthy while keeping the flavors you love.
Take Action:
At a family gathering, Auntie Reshma declares, “High blood pressure is just stress. Drink some chamomile tea and it will go away.” Uncle Mohan adds, “Only fat people get high blood pressure. I’m thin, so I’m fine.” These well-meaning but dangerous myths circulate in many South Asian families.
| # | Myth | Fact |
|---|---|---|
| 1 | High blood pressure is just stress – it’s not serious. | While stress can raise blood pressure temporarily, chronic high blood pressure is a medical condition that damages organs even when you’re relaxed. |
| 2 | Only overweight people get high blood pressure. | Thin South Asians can have high blood pressure, especially due to genetics, salt intake, and belly fat even at normal weight. |
| 3 | If I feel fine, my blood pressure must be normal. | High blood pressure usually has no symptoms until organs are seriously damaged. |
| 4 | Blood pressure medication is addictive. | These medications are not addictive. Your body needs them to maintain safe blood pressure levels. |
| 5 | Natural remedies are always safer than medication. | While lifestyle changes are important, uncontrolled high blood pressure can cause heart attacks and strokes. |
| 6 | Young people don’t get high blood pressure. | South Asians can develop high blood pressure in their 30s and 40s. |
| 7 | I can stop taking medication when I feel better. | Blood pressure medication prevents future problems, not just current symptoms. |
| 8 | Home blood pressure monitors aren’t accurate. | Validated home monitors can be very accurate and provide important information. |
Common Myth: “Our traditional diet is automatically healthy.”
Truth: Traditional South Asian cooking can be very healthy, but modern versions often include too much salt, oil, and refined grains.
Sanjay’s blood pressure is 138/88. His doctor mentions medication, but Sanjay heard that 140/90 used to be the cutoff. He’s confused about when medication is really necessary.
The Guidelines Have Changed: The American Heart Association (AHA) and American College of Cardiology (ACC) now recommend a lower threshold of ≥130/80 mm Hg (stage 1) for the diagnosis of hypertension, whereas previous guidelines used ≥140/90 mm Hg.
When Medication is Usually Recommended:
We advise considering high-CVD-risk race/ethnicity (e.g. South Asian) as a risk-enhancing factor. This means doctors may recommend medication at lower blood pressure levels for South Asians than for other groups.
Starting Treatment: Most doctors start with one medication and add others if needed. It may take 2-3 months to find the right combination and dose.
Common Myth: “Once I start blood pressure medication, I’ll need it forever.”
Truth: While most people need long-term treatment, some can reduce or stop medication with significant lifestyle changes.
Kamala always feels rushed during doctor appointments and forgets to ask important questions. By the time she gets home, she realizes she doesn’t really understand her blood pressure situation.
Common Myth: “Doctors don’t have time for lots of questions.”
Truth: Good doctors want you to understand your condition and make informed decisions.
Rajesh knows his father has high blood pressure but won’t take it seriously. His wife is pre-diabetic and stressed about work. His teenage daughter eats mostly junk food. He wants to help his whole family but doesn’t know where to start.
Older South Asian adults often resist changes or modern medicine. Approach with respect and patience:
South Asian teens often adopt Western fast food while losing traditional healthy eating patterns:
Common Myth: “You can’t teach old dogs new tricks – elderly parents won’t change.”
Truth: Older adults often become very motivated to change when they understand the benefits.
Priya started taking blood pressure medication but her doctor wants to see how it’s working. She needs to track her readings but doesn’t know the best way to keep organized records.
How to Track Effectively: Take readings at the same times each day (morning and evening), record before taking medication, note any unusual circumstances (stress, poor sleep, illness), and bring your log to every doctor appointment.

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.
