Framingham Risk Score Calculator

The Framingham Risk Score (FRS) is a validated clinical tool that estimates a person's 10-year probability of developing cardiovascular disease (CVD), including coronary artery disease, stroke, peripheral vascular disease, and heart failure. It was derived from the long-running Framingham Heart Study and is widely used in primary prevention settings.

The FRS is intended for adults aged 30 to 79 years without pre-existing cardiovascular disease. It is not meant for patients who already have a known CVD diagnosis, as these individuals are already considered high risk and require active management regardless of their score.

A 10-year risk below 10% is considered low risk, 10–20% is intermediate risk, and above 20% is high risk. High-risk patients typically warrant more aggressive lifestyle interventions and may be candidates for lipid-lowering therapy or other preventive treatments.

Men and women use separate scoring equations because cardiovascular risk factors have different weights by sex. For example, age and cholesterol contribute differently to absolute risk in males versus females. The 2008 model provides sex-specific coefficients to ensure accuracy for both groups.

The 2008 Framingham model does not formally include family history as a variable. However, clinical guidelines commonly recommend doubling the calculated FRS when a patient has a first-degree relative with premature coronary artery disease (men under 55, women under 65) to account for this added risk.

Being on antihypertensive medication indicates that blood pressure is being actively managed, but it also implies the patient has a history of elevated blood pressure. The Framingham model assigns a higher coefficient to treated systolic blood pressure because treated hypertension still carries residual cardiovascular risk beyond what the blood pressure reading alone suggests.

Heart age is an estimate of the age at which a person with all optimal risk factor values would have the same calculated CVD risk as the patient. A heart age higher than chronological age signals accelerated cardiovascular aging and can be a motivating way to communicate risk to patients.

A high score should prompt a conversation with a healthcare provider about lifestyle modifications such as smoking cessation, dietary changes, and increased physical activity, as well as consideration of pharmacological interventions like statins or antihypertensives. The FRS is a screening tool to guide clinical decision-making, not a definitive diagnosis.
