Thanks for using this CVD calculator! Our Primary Care Simplified Lipid Guidelines (2023) have now been published and a new version of this calculator is available at

The updated calculator and guideline include updated evidence and simplified approaches to treatment. We encourage you to switch to the revised calculator and check out our updated guideline.



Gender MaleFemale
Race BlackNon-Black
Smoker YesNo

CVD risk is reversed after 5-10 years of no smoking

Diabetes YesNo

Systolic Blood Pressure


Enter present blood pressure regardless of treatment

120 mmHg is used for baseline risk

On treatment for BP YesNo

Click YES if taking blood pressure medication

Only applies if SBP is greater than 120 mmHg

On lipid-lowering treatment YesNo

Click YES if taking lipid-lowering medication

On antithrombotic treatment YesNo

Click YES if taking antiplatelet/anticoagulant medication

Total Cholesterol


Cholesterol should be prior to drug treatment

3 mmol/L is used for baseline risk.
Click to change to mg/dL.

116 mg/dL is used for baseline risk.
Click to change to mmol/L.

HDL Cholesterol


HDL should be prior to drug treatment

1.3 mmol/L is used for baseline risk.

50 mg/dL is used for baseline risk.

Family History of CVD YesNo

Angina or heart attack in a 1st degree relative < 60 yrs

Chronic Kidney Disease YesNo

CKD status is not part of the risk algorithm but is used for calculating the benefit of certain therapies

Atrial Fibrillation YesNo
Deprivation Quintile

This socioeconomic deprivation index can be determined by answering eight questions. For detailed information, see page two of the NZDep2013 brief flyer or visit the website.

Rheumatoid Arthritis YesNo





BMI of 25 kg/m2 for baseline risk

Family History of Early CHD


The amount of additional risk (relative increase in risk) conferred from a family member to a patient depends on: (1) how close a relative, (2) age of a relative, (3) number of affected family members.

If mother (< 65 yrs) increase risk 60%

If father (< 55 yrs) increase risk 75%

Relative Benefit:  

Benefit often has nothing to do with the effect on the surrogate marker. At present, you can only select one intervention at a time.

  • Physical Activity
  • Mediterranean Diet vs Low fat
  • Vitamin/Omega-3 supplements
  • BP meds (not atenolol/doxazosin)
  • Low-mod intensity statins
  • High intensity statins
  • Fibrates
  • Niacin
  • Ezetimibe
  • Metformin
  • Sulfonylureas
  • Insulins
  • Glitazones
  • GLPs
  • DPP-4s
  • Meglitinides
  • SGLT2
  • Smoking Cessation
  • ASA
