10-Year Heart Risk Calculator

A note from Kyle Keith, PA-C: Most people have never seen their 10-year heart risk number. This tool uses the same equations now recommended by the AHA. Enter your most recent numbers — the Plain Medicine explanation of what your result means is yours to keep.

About You

Age Between 30 and 79

Sex Biological sex at birth

Cholesterol (from recent labs)

Total Cholesterol mg/dL — find this on your most recent lipid panel in your patient portal or lab printout. It is usually labeled Total Cholesterol.

HDL Cholesterol mg/dL — on the same lipid panel, labeled HDL or HDL-C. This is the "good" cholesterol — higher is better.

Don't have your cholesterol numbers? This is a good reason to request a lipid panel at your next visit. Ask your provider for your total cholesterol and HDL — then come back and calculate your risk. Most patients can access recent lab results through their patient portal.

Blood Pressure

Systolic Blood Pressure The top number of your blood pressure reading — e.g. if your BP is 128/82, enter 128. Use your most recent reading from a provider visit, home monitor, or pharmacy cuff.

On BP medication? Any medication prescribed to lower your blood pressure — including lisinopril, amlodipine, metoprolol, hydrochlorothiazide, and others.

Medical History

Do you have diabetes? Type 1 or Type 2 diabetes — including if you are on diabetes medication or were told your blood sugar is diabetic range.

Do you currently smoke? Current cigarette smoker — not former smoker. If you quit, select No.

Body & Kidney

BMI Body Mass Index. Don't know yours? Search BMI calculator online — you'll need your height and weight. Or ask your provider — it is calculated automatically at every visit.

eGFR (optional) A kidney function number from your metabolic panel — labeled eGFR or GFR. Normal is 60 or above. Leave blank if unknown — the calculator will assume normal kidney function.

Don't have your BMI or eGFR? Your BMI is calculated at every provider visit and is in your chart. Your eGFR is on your most recent basic or comprehensive metabolic panel. Both are available in your patient portal. The calculator will run without eGFR — but including it improves accuracy.

Please fill in Age, Cholesterol, HDL, Blood Pressure, and BMI before calculating.

Important: This calculator uses the 2023 AHA PREVENT equations (Khan SS et al., Circulation 2024;149:430–449). It is an educational estimate only and does not constitute medical advice, diagnosis, or treatment. For use in adults ages 30–79 without a history of cardiovascular disease (primary prevention only). Results are not a substitute for a conversation with your provider.

Input ranges: Total cholesterol 130–320 mg/dL · HDL 20–100 mg/dL · Systolic BP 90–200 mmHg · BMI 15–60 · eGFR 15–140. Values outside these ranges will be clamped to the nearest valid input.
