Framingham, and the Scottish ASSIGN score. NICE currently recommend binary option charts of the JBS formula.
ASSIGN is tailored to the Scottish population. The BNF calculation option provided on this site is designed to correspond as closely as possible to the official published charts. As such, the LVH and diabetes risk factors originally incorporated in Framingham, are not included in the JBS charts as these patients are automatically considered high risk. ASSIGN is therefore tailored to the Scottish population. This option may be used to produce charts similar to those produced by the JBS. CVD death – risk of dying from cardiovascular disease, based on Framingham.
CHD death – risk of dying from coronary heart disease, based on Framingham. The definitions of “cardiovascular disease” vary depending on the equation used, and are detailed below. This definition is the one used in the printed charts. The BNF calculation assumes that the person does not have diabetes. The Joint British Societies advise that in individuals with a positive family history, the risk can corrected be multiplying by 1.
This feature is not included on this website. The Framingham calculations include LVH as a risk factor. LVH refers to the original Framingham ECG criteria. It is important to distinguish this from echocardiographic findings of LVH, which are more common, or other ECG criteria such as the Sokolow-Lyon criteria or those employed by automated ECG reporting. ASSIGN incorporates SIMD as a risk factor. SIMD is assumed to be 20 if left blank and no postcode is given. In contrast, Framingham and BNF use the total:HDL cholesterol ratio.
