Cardiovascular Risk Calculator
Estimate your 10-year risk of heart attack or stroke using the World Health Organization’s published risk charts for the Southeast Asia region, which includes Thailand.
Why Cardiovascular Risk Screening Matters in Thailand
Heart disease and stroke are among the leading causes of death in Thailand, and the trend has been getting worse rather than better. Because early-stage cardiovascular disease usually has no symptoms, a risk calculator like this one is often the first signal that it’s worth having your blood pressure and cholesterol properly checked, before a heart attack or stroke forces the issue.
Understanding the Risk Factors in This Calculator
Every input in this tool is a factor with a well-established, independent link to cardiovascular disease. Here’s what each one means and why it’s included.
Age & sex
Risk rises with age for both sexes, and men typically carry higher risk than women at the same age until women reach menopause, when the gap narrows.
Smoking
Smoking roughly doubles cardiovascular risk in most age groups and is one of the few risk factors that can improve significantly within a year of quitting.
Blood pressure
Systolic (top-number) blood pressure is one of the strongest predictors in the model. Risk increases steadily across every 20 mmHg band above 120 mmHg.
Total cholesterol
Higher total cholesterol contributes to plaque buildup in the arteries over time. A fasting lipid panel gives the most accurate reading.
Diabetes
A diagnosis of diabetes roughly doubles cardiovascular risk at a given age, which is why it changes which chart column your result is read from.
BMI
Used only in the non-lab version as a practical substitute for cholesterol when a blood test isn’t available. It’s a rougher estimate, particularly for people with diabetes.

How to Lower Your Cardiovascular Risk
Every factor in this calculator except age and sex can be improved, and doing so measurably lowers real-world risk over time. None of this replaces medical advice tailored to you, but these are the changes with the strongest evidence behind them.
Quit smoking
The single highest-impact change available. Cardiovascular risk starts dropping within months of quitting.
Control blood pressure
Regular monitoring, reduced salt intake, and medication when prescribed all meaningfully lower systolic pressure over time.
Manage cholesterol
Diet, activity, and medication when indicated can bring total cholesterol into a healthier range.
Stay physically active
Regular moderate activity supports healthy blood pressure, weight, and cholesterol together.
Manage diabetes closely
Good blood sugar control reduces the extra cardiovascular risk that comes with a diabetes diagnosis.
Get regular checkups
Blood pressure and cholesterol can be high for years with no symptoms. Testing is the only way to know for sure.
Frequently Asked Questions
This tool provides a general estimate for educational purposes and is not a medical diagnosis. It is intended for adults aged 40–74 with no personal history of heart attack, stroke, or other cardiovascular disease. It does not replace a consultation, physical examination, or blood test ordered by a licensed physician. No data you enter is stored or transmitted — all calculations happen in your browser.
