Ethnic groups within Britain have differing risk of coronary heart disease (CHD) and cardiovascular disease (CVD) at the same level of risk factors. This calculator adjusts for ethnic group and is based on a re-calibration of the Framingham risk equations. It also provides the standard Framingham estimates. The method uses the prevalence ratios for CHD and CVD for each ethnic group compared to the general population, and adjusts for differences in mean risk factor levels and prevalence of smoking between each ethnic group.

Ten-year risk of CHD and CVD is calculated using ethnic group, sex, age, systolic blood pressure (SBP), total cholesterol, high-density lipoprotein (HDL) cholesterol and smoking status (current smoker or not). The calculator can be applied to people aged 35 to 74 without diabetes or a previous history of CVD.

The definition of CHD used in this Framingham score is death from CHD (sudden or non-sudden) , myocardial infarction, angina pectoris and coronary insufficiency. The definition of CVD additionally includes stroke and transient ischemia.
