American (National Cholesterol Education Program) and European guidelines uses the FRS to classify people for primary prevention. Those with score <10% are classified as low risk, 10-20% as moderately high risk and >20% as high risk.

People with established CVD (cardiovascular disease) or diabetes are already at high risk of CVD events and are targeted for maximum aggressive therapy with an LDL goal of <100 mg/dl, with an optional goal of LDL<70 mg/dl in very high risk patients.¹ Those who have high triglycerides should also meet the non-HDL-C goal which is set at 30 mg/dl higher than the LDL goal.

The FRS is derived from the landmark Framingham Heart Study (FHS) that has provided valuable insights into CAD (coronary artery disease) risk prediction. The FRSis based on the clinical experience and coronary events of 5,209 men and women (aged 28-62 years) followed since 1948 and have guided the delivery of preventive cardiology for half a century.²

Launched in 1948, blood pressure readings for each subject were taken at two year intervals for a period of 14 years and the findings dispelled several myths that existed then and shared by some even today.³One such myth was “ The greatest danger to a man with blood pressure lies in its discovery because some fool may try to treat it.”⁴The first key finding from the study was that both systolic blood pressure (SBP) and diastolic blood pressure (DBP) are key markers of cardiovascular risk, especially stroke, heart failure, and heart attacks.³

Weighted scores are assigned to 6 easily measurable constructs─ total cholesterol (TC), HDL-C, systolic blood pressure, treatment of hypertension, smoking status, age and gender.⁵

Overestimation and Underestimation of the Risk

D’Agostino et al ⁸ applied FRS calculations to 6 prospectively studied, ethnically diverse populations within the US. It was discovered that the FHS performed well for whites and blacks. Among Japanese American and Hispanic men and Native American women, the FRS systematically overestimated the risk. After recalibration, taking into account different prevalence of risk factors and underlying rates of developing CAD, the authors were able to construct more accurate models for those subgroups whose risk was overestimated by the conventional method. ⁸

The prediction of absolute risk was not very accurate when a model derived from one study was applied to a different study or population.⁹ The FRS has been shown to substantially overestimate the risk, when applied to northern Europeans (including UK, Belfast) with high risk of CAD and particularly in southern Europeans with low risk of CAD. ^10-13 Over 50% of the variance in CAD death rates in 25 years was accounted for by the difference in mean serum cholesterol.¹⁴ The overestimation was as high as 2-fold among Spaniards and 4-fold among Chinese, but the accuracy could be improved by recalibration.¹²

The FRS systematically overestimated the absolute CAD risk in the Chinese Multi-provincial Cohort Study (CMCS). This cohort consisted of 30,121 adults aged 35-65 years at baseline and was followed for 12 years. The 10-year CAD rate of the CMCS cohort was one-fifth that of the Framingham cohort.

For example, in the 10th risk decile, the predicted rate of CAD death in men was 20% CMCS vs. an actual rate of 3%. The proportion of Chinese people with 10-year risk exceeding 10% was 9.9% by FRS estimate but only 0.35 by the CMCS functions. ⁶ The recalibration of the FRS using the mean values of risk factors and mean CAD incidence rates of the CMCS cohort substantially improved the performance of the FRS functions in the CMCS cohort. ⁶ Nevertheless, application of recalibrated FRS models again significantly overestimated the CAD risk in both men (by approximately 97%) and women (by approximately 228%).

Stroke is much more prevalent than CAD in China; thus, any risk prediction model only for CAD may not be appropriate in application. In another study involving 9903 Chinese followed for 17 years, of the 371 CVD events, 266 were ischemic strokes and 105 were coronary events.¹⁵

Recently a simplified point score model has been developed and tested for estimating the 10-year integrated cardiovascular risk (Ischemic stroke and heart attack) in Chinese, in whom stroke is the predominant form of CVD. This model uses age, systolic blood pressure, smoking, total cholesterol, diabetes and BMI (body mass index).¹⁵ Since overestimation of the risk in Chinese population could result in over treatment, the Framingham risk function cannot be used without calibration.

In sharp contrast to the Chinese the FRS underestimate the risk of CAD among Indians by 200%.⁷ See Underestimation of risk among Asian Indians.

Recalibrating the Framingham equations to the event rate and the prevalence of the risk among Spaniards and Chinese have been shown to improve the prediction of the risk. After calibration, the FRS function became an effective method of estimating the risk .⁸ The FRS-based coronary risk chart overestimates absolute coronary risk in populations characterized by a lower incidence of CAD events and should be used with caution.

Limitations of the FRS

The FRS is recommended only for patients with > 2 risk factors and is not accurate in patients with extreme end of a particular risk factor such as heavy smoking or very high cholesterol level.

FRS uses TC (instead of LDL-C) and does not include risk factor modification interventions, except for hypertension. It does not include family history or south Asian ethnicity both of which are known to confer 2-fold risk of future CAD ^{16, 17} It also does not include other identified risk factors such as overall and abdominal obesity, physical inactivity, metabolic syndrome, high lipoprotein(a), high triglycerides, non-HDL-C, apolipoprotein B, C-reactive protein, fibrinogen, left ventricular hypertrophy, estimated glomerular filtration rates etc.

The FRS includes only CAD events but excludes other vascular events such as stroke, which are more common than heart attack in Asian populations. The scoring was developed by studying a predominantly white and middle class population and particularly useful in the elderly but not be accurate for young and people of other ethnic origin. ^{18, 19}

The young subjects in FHS were not only underrepresented but had very few events, which led to its heavy emphasis on age and is unsuitable for predicting premature CAD (defined as 55 years and younger in men and 65 years and younger in women). In a study of 220 patients with premature heart attack (mean age 50, 25% women), almost 70% were classified as low risk by FRS and only 25% met criteria to qualify for medication prior to the heart attack. For women in this population, only 18% met criteria for treatment.²⁰

People with metabolic syndrome have recently been found to have a 53% higher mortality than is found in people without diabetes or metabolic syndrome. The metabolic syndrome and its components help predict the risk independent of Framingham risk score in people with in diabetics and nondiabetics alike.

10-year risk and lifetime risk: A major limitation of FRS is that it estimates the risk of developing CAD within only a 10-yr period. Among young individuals, there is marked disparity between 10-year risk and lifetime risk in the FHS. For example, a 50-year old man in the lowest risk tertile had a 10-year risk of only 4% but a life time risk of 50%. Ford et al have recently estimated that only 3% of the US population would be classified as CAD risk equivalents and therefore qualify for intensive lipid therapy.²¹ Thus, FRS may not identify subjects with low short-term but high lifetime risk for CAD ²²

These data underscore the need for continued vigilance in those who have been found to be at low short-term risk. Likewise it may underestimate the risk in populations highly prone for premature CAD.

Framingham Risk Score is the estimation of 10-year cvd (cardiovascular disease) risk of a person. It was developed by the Framingham Heart Study to assess the hard coronary heart disease outcome. It is used to estimate the risk of heart attacks in adults older than 20.
In the below calculator enter your gender, age, cholestrol level, BP and you get the 'Framingham Risk Score' and the risk of developing CHD. Higher the score, higher is the percentage of developing CHD.
