Information for health professionals

The probability that an individual will develop cardiovascular disease within a given period of time depends on the combination and intensity of all their identified risk factors, rather than on the presence of any single risk factor.


Using an absolute risk approach takes into account the cumulative and sometimes synergistic effects of these multiple risk factors. Clinical decisions based on absolute cardiovascular disease risk levels can lead to improved health outcomes, because they direct the right treatments to those who can benefit most. The absolute risk approach is emphasised by several Australian and international primary care guidelines, and supported by robust evidence.

Who should have their absolute risk assessed?

Absolute cardiovascular risk assessment, using the Framingham Risk Equation to predict risk of a cardiovascular event over the next 5 years, should be performed for all adults aged 45+ years (or 30+ years for Aboriginal and Torres Strait Islander peoples) without existing cardiovascular disease or not already known to be at increased risk of cardiovascular disease (see Box 1 below).

For specific population groups, additional recommendations include: 

  1. Combined early screening for diabetes, chronic kidney disease and cardiovascular risk factors in Aboriginal and Torres Strait Islander adults from the age of 18 years.

  2. Assessments in Aboriginal and Torres Strait Islander adults from 30 years at the latest (rather than 45 years). Although the Framingham Risk Equation might underestimate risk in this population, available evidence suggests that this approach will provide an estimate of minimum cardiovascular risk. 

  3. Assessments in adults with diabetes aged 45—60 years (rather than 45—74 years). Although the Framingham Risk Equation might underestimate risk in this population, available evidence suggests that this approach will provide an estimate of minimum cardiovascular risk.

  4. In adults who are overweight or obese, the results of the assessment should be interpreted with the awareness that its predictive value has not been specifically assessed in this population.

  5. In adults with atrial fibrillation (particularly those aged over 65 years), an increased risk of cardiovascular events and all-cause mortality, in addition to thromboembolic disease and stroke, should be taken into account. While cardiovascular disease risk is known to be elevated for this population, it is not possible to quantify the degree of additional cardiovascular disease risk in an individual. Clinical judgement is necessary when assessing overall cardiovascular risk.

Adults with any of the conditions in Box 1 are already known to be at increased absolute risk of cardiovascular disease and do not require further assessment using the Framingham Risk Equation.

 Box 1. Adults already known to be at increased absolute risk of cardiovascular disease

  • Diabetes and age > 60 years

  • Diabetes with microalbuminuria (> 20 mcg/min or urinary albumin:creatinine ratio > 2.5 mg/mmol for males, > 3.5 mg/mmol for females)

  • Moderate or severe chronic kidney disease (persistent proteinuria or estimated glomerular filtration rate < 45 mL/min/1.73 m2)

  • A previous diagnosis of familial hypercholesterolaemia**

  • Systolic blood pressure ≥ 180 mmHg or diastolic blood pressure ≥ 110 mmHg

  • Serum total cholesterol > 7.5 mmol/L

What is included in a full absolute risk assessment?*

To make a full assessment of your patient’s absolute cardiovascular risk, you will need to take into consideration the following factors:

  • Age† and sex†

  • Smoking status†

  • Serum lipids†

  • Blood pressure†

  • Waist circumference and body mass index

  • Nutrition

  • Physical activity level

  • Alcohol intake††

  • Family history of premature cardiovascular disease

  • Social history including cultural identity, ethnicity, socioeconomic status‡ and mental health

  • Diabetes

  • Chronic kidney disease

  • Urine for microalbumin and protein

  • Familial hypercholesterolaemia**

  • Evidence of atrial fibrillation (history, examination, electrocardiogram)

* Some recommendations were derived from the systematic review, while others are consensus statements developed where the systematic literature review process was undertaken, but no evidence was found for or against the recommendation. For details see NVDPA’s Guidelines for the assessment of absolute cardiovascular disease risk.

†† Alcohol is a risk factor for elevated blood pressure (which is itself a major independent determinant of risk of atherosclerotic disease), stroke and cardiomyopathy. For a full discussion of this, please see the National Health and Medical Research Council’s (NHMRC) Australian guidelines to reduce health risks from drinking alcohol.
‡ Risk assessment requires consideration of socioeconomic deprivation as an independent risk factor for cardiovascular disease. Absolute cardiovascular risk calculated using the Framingham Risk Equation is likely to underestimate cardiovascular risk in socioeconomically deprived groups.
