Assess your cholesterol levels and cardiovascular risk.
Cholesterol risk is assessed using multiple factors. Here's the breakdown:
Cholesterol guidelines:
Key insight: The ratio of total cholesterol to HDL is a better predictor of heart disease risk than total cholesterol alone.
Result = Validated health or fitness equation applied to the measurements and options entered. Review the methodology and limitations before interpreting the estimate.The estimate uses the measurement, age and other fields requested by the selected equation. Laboratory methods, units, timing, medication, medical history and population-specific limitations can materially affect interpretation.
The Cholesterol Risk Calculator can calculate your chances of developing a cardiovascular condition based on cholesterol numbers and certain factors that can affect the risk of cardiovascular disease. Inputs depend on the specific calculator but can include age, gender, total cholesterol, HDL cholesterol level, blood pressure, smoking status, diabetes and any cholesterol medication that has been prescribed. Note that the calculation is an estimate and it is not a medical diagnosis of whether you currently have heart disease or guidance on if and when you should start, stop or modify treatment.
Please provide the information as accurately as you can. If you have readings from recent examinations or test results, then input them from your latest readings.
Do not substitute LDL cholesterol for total cholesterol or HDL cholesterol. These are different laboratory measurements and are not interchangeable.
A cholesterol risk calculator is not meant to indicate risk based just on your cholesterol - the cardiovascular disease models we currently use involve numerous risk factors and calculation factors like the ones outlined below in the AHA PREVENT equations (which consider age, sex, blood pressure, cholesterol levels, body mass index, kidney function, diabetes, tobacco usage, and whether the patient is on applicable medication treatments) and prior calculators like the ASCVD Pooled Cohort Equations.
Since valid models may use different variables and definitions, you can obtain different estimates when using several of these calculators or. It's important to specify in a calculator its model when one interpretes his. The results will not reflect different people but potentially different estimates about the.
There is no single universal formula—call it a "risk formula"—or one class of cardiovascular risk calculator that applies to every individual. Instead, risk calculators use validated statistical equations derived for specific populations and endpoints.
For instance, The traditional ACC/AHA Pooled Cohort Equations to calculate the 10-year risk of ASCDV employ factors for age, gender and race along with total and HDL cholesterol, systolic blood pressure, prescription for hypertension, diabetes, status as a smoker, and others. New PREVENT equations use different predictive models with other cardiac, renal and metabolic factors included.
These equations contain factors and transformations to the model hence a simpler equation should never be entered instead of the true validated calculation. Any calculator the user employs must apply the actual equation corresponding to the model the tool diagnoses.
Consider an illustrative adult entering the following information into a calculator that requests these variables:
These are sample inputs, not an interpretation of the situation and they are not an indication of the risk level of a given person. The risk model that the calculator utilizes will have valid inputs processed through its own sex- and model-specific coefficients to arrive at the applicable risk level. Don't translate this example into a percent; you can't do that with out specifying precisely which model and version of the risk equation the calculator is using.
Usually the result you get back from a Cardiovascular disease risk calculator will tell you an estimate in percentage risk over a period such as 10 years. What that percentage actually signifies will vary with the algorithm, ages, population group, outcome and input values.
An increased risk score implies that the factors entered in to the model are generally associated with a higher predicted probability of the cardio vascular event. It does not guarantee the person is more likely to have an event.
Your Risk Assessment should be viewed in addition to other medical and family history data. When deciding upon a patients global cardiovascular risk a healthcare professional will also take into account prior cardiovascular disease history, family history, high cholesterol/lipids, blood pressure/hypertension, renal functionality, diabetes, medications, smoking history, risk-enhancing factors etc.
You should not use a calculator to display percentages alone to know if a person should start or stop taking or changing their blood pressure medicine or cholesterol medicine.
A calculator offers an approximation from a statistical formula. It can’t look directly at your arteries to diagnose heart disease, tell you the specific reason for an cholesterol disorder or tell you what you specifically are going to experience.
Risk scores may also be designed and validated for specific populations or age groups. These may be less relevant if a person is in a population or on measurement ranges different from what was selected when developing the model.
Different models can arrive at different estimates for the same variable as they may have different predictors, equations, populations and cardiovascular outcomes. Results from one model should not be compared to results from another model as if they are measuring the same thing.
Individuals with preexisting cardiovascular disease, extremely high cholesterol levels, other significant medical conditions or other conditions may need to be assessed in the clinic and not just have a primary-prevention risk calculation applied.
Please note that this calculator is for information only and is not a substitute for personal medical advice. If your questions relate to diagnosis, medication, treatment, pregnancy, serious symptoms or major concerns about your heart then please discuss your results with a suitably qualified healthcare professional.
These models incorporate cholesterol levels along with other risk factors in their calculations. A model may yield an estimate of a person's ASCVD risk over time or a broader cardiovascular risk depending on which model is used.
No. Cholesterol is just one factor that contributes to risk for cardiovascular disease. You cannot use a cholesterol level alone to diagnose heart disease, and a risk calculator cannot substitute for proper clinical assessment.

Cardiovascular Health Cholestolis measured differently in countries other than the United States Some laboratories and calculators may display results inmmol/L, others in mg/dL. Don’t use numbers for one system to stand in for the others.
Risk stratification models could be one piece in a clinician/patient discussion on cardiovascular prevention; but, in no case does the Calculator itself justify a medication trial or not justify it. The medical indication is complex.
Each calculator may apply equations that have been validated using a separate set of predictor variables, populations age groups or cardiovascular risk outcomes. It should therefore not be assumed that calculations from any two calculators should yield similar results.
Use a recent value from a reliable measurement source and verify the unit before calculating. Discuss unexpected or abnormal results with a qualified clinician rather than changing treatment based on the calculator.
Cholesterol is a component of evaluating cardiovascular risk. Established risk equations take into account total cholesterol and HDL cholesterol, but it is the overall risk estimation that is influenced by factors such as age, blood pressure, presence of diabetes, smoking and medication usage.
Total cholesterol andHDL cholesterol are two separate values and may not be entered in the same box. Total cholesterol describes cholesterol contained in several lipoprotein particles. HDL cholesterol describes the cholesterol contained in high-density lipoproteins.
| Measurement | Common U.S. Unit | Use in Risk Assessment |
|---|---|---|
| Total cholesterol | mg/dL | Used by several cardiovascular risk equations |
| HDL cholesterol | mg/dL | Used by several cardiovascular risk equations |
| LDL cholesterol | mg/dL | Important lipid measurement, but not interchangeable with total cholesterol or HDL |
| Non-HDL cholesterol | mg/dL | Used by some newer cardiovascular risk models |
In America, results for cholesterol are generally in mg/dL. However, on occasions cholesterol is reported using mmol/L by overseas laboratories. The calculator will need to adhere to the units for which its internal calculations expect. If conversion is necessary it is best performed before entering into the calculator, rather than mixing units in a single calculation.
It is a statistically computed percentage to give us an estimated probability on the outcome over the time span specified by the risk model. A calculated risk of 10 year cardiovascular risk is different from lifetime cardiovascular risk.
The resulting percentage should be thought of as an estimate for your risk within a population of similar people and not as a guarantee that an event will or will not take place. A low result does not ensure that you’ll never develop heart problems, nor does a high score necessarily indicate that an event is imminent.
A calculator result does not always address all elements needed to evaluate an individual for a future risk of cardiovascular disease. History of cardiovascular disease, personal family history of cardiovascular disease, co-morbidities, kidney disease, pregnancy history, medication history and other CVD risk factors may warrant further clinical assessment.
There is thus no reason, then, not to let the calculator act as an assistant for clinical decision-making, for training and for information without becoming an appraisal medical device.
If systolic pressure is considered as one factor for your cardiovascular risk model, there is a risk of having a wrongful estimate reading due to erroneous reading. There is always variations between blood pressure readings therefore always use the instructions on taking correct measure and make use of an actual reading instead of guessing.
A reading of your cholesterol level and a calculation of cardiovascular risk tell you two quite different things. Your cholesterol test will give you an estimate of the concentration of cholesterol in your blood, and a calculator of risk will help you find an estimate of your chances of having a certain cardiovascular event in a certain time.
As such, the cholesterol number shouldn't be read as if it were equivalent to the percentage cardiovascular risk.
As relevant inputs change, the risk estimate can change. Factors influencing the calculations will depend on the model used, but may include age, blood pressure, cholesterol numbers, whether someone smokes, has diabetes, kidney function and current medications. If your laboratory or clinical measures are updated, make sure to plug those updated numbers into the recalculations of your estimates.
Your results are an estimate based on the details you have provided and the risk model used by the Cholesterol Risk Calculator. Cholesterol Risk Calculator is not intended for diagnosing cardiovascular disease or making any autonomous decisions about medication or treatment. Speak to your health care provider if the risk assessment worries you, or if you consider that you are experiencing serious risk factors or symptoms of cardiovascular disease.
