Summary of risk assessment methods based on the Framingham equations
| Table | Age (years) | Risk assessed | Risk factors included | Format | |||
| Sheffield | Men 30–70, women 35–70 (in 2 year intervals) | 10 year CHD ⩾ 30% | Age, sex, smoking (Y/N), hypertension (Y/N), diabetes (Y/N), LVH (Y/N), total cholesterol | Tables for men and women; cholesterol concentration at which risk ⩾ 30% | |||
| Modified Sheffield | Men 26–70, women 34–70 (in 2 year intervals) | Annual CHD ⩾ 3.0% and ⩾ 1.5% | Age, sex, smoking (Y/N), hypertension (Y/N), diabetes (Y,N), total:HDL cholesterol ratio, LVH (age+20 years) | Tables for men and women; total:HDL cholesterol ratio at which risk ⩾ 1.5% and ⩾ 3.0% | |||
| Joint British guidelines | 30–70 (in four decades) | 10 year CHD risk, 3 bands: < 15%, 15–30%, > 30% | Age, sex, smoking (Y/N), SBP (110–210 mm Hg), diabetes (Y/N), total:HDL cholesterol ratio | Graph of SBPv total:HDL cholesterol ratio; three risk categories colour coded; separate graphs for each permutation of sex, diabetes, smoking, and decade of age | |||
| Revised joint British guidelines | 35–74 (in four decades) | ||||||
| Canadian | 30–70 (in 2 year intervals) | 10 year CHD risk | Age, sex, smoking (Y/N), SBP (98–185 mm Hg), diabetes (Y/N), LVH (Y/N), total cholesterol (3.59–8.53 mmol/L), HDL cholesterol (0.65–2.48 mmol/l) | Graph of riskv age for men and women; risk modified by addition/subtraction of points for risk factors | |||
| Framingham categorical | 30–74 | 10 year CHD risk | Age, sex, smoking (Y/N), SBP, diabetes (Y/N), LVH (Y/N), total cholesterol, HDL cholesterol | Summation of points for risk factors: table for conversion to CHD risk | |||
| New Zealand | 40–70 (in four decades) | 5 year CVD risk in six bands: < 2.5%, 2.5–5%, 5–10%, 10–15%, 15–20%, and > 20% | Age, sex, smoking (Y/N), SBP (120–180 mm Hg), diabetes (Y/N), total:HDL cholesterol ratio | Matrix of cells with colours corresponding to different CVD risk levels; rows relate to blood pressure levels, columns to cholesterol:HDL ratios; different matrices for each permutation of sex, diabetes mellitus (Y/N), smoking (Y/N), and for each of four decades of age | |||
| Updated New Zealand | 5 year CVD risk in eight bands: < 2.5%, 2.5–5%, 5–10%, 10–15%, 15–20%, 20–25%, 25–30% and > 30% | ||||||
| Joint European guidelines | 30–70 (in four decades) | 10 year CHD risk in five bands: < 5%, 5–10%, 10–20%, 20–40% and > 40% | Age, sex, smoking (Y/N), SBP, diabetes (Y/N), total cholesterol | Similar design to New Zealand tables | |||
CHD, coronary heart disease; HDL, high density lipoprotein; LVH, left ventricular hypertrophy; SBP, systolic blood pressure.
