Notes

• MESA: Multi-Ethnic Study of Atherosclerosis; CAC: coronary artery calcification; HDL: high-density lipoprotein; MI: myocardial infarction; ASCVD: atherosclerotic cardiovascular disease; CHD: coronary heart disease.
• This calculator helps predict the 10-year risk of the following ASCVD events:
  • CHD death
  • Nonfatal MI
  • Resuscitated cardiac arrest
  • Coronary revascularization in patient with angina
• When a CAC score is known, a second 10-year risk calculation is done using independent hazard ratios associated with CAC scores.

 
Equations used
 

Terms = (Age * 0.0455) + (Sex * 0.7496) + ((Race == 1?1:0) * -0.2111) + ((Race == 2?1:0) * -0.5055) + ((Race == 3?1:0) * -0.19) + (Diabetes * 0.5168) + (Smoker * 0.4732) + (Totalcholesterol * 0.0053) - (HDLcholesterol * 0.0140) + (On lipid-lowering medication * 0.2473) + (Systolic blood pressure * 0.0085) + (On hypertension medication * 0.3381) + (Family history of MI * 0.4522)

10-year risk = 100 * (1 - 0.99963e(Terms))

Terms CAC = (Age * 0.0172) + (Sex * 0.4079) + ((Race == 1?1:0) * 0.0353) + ((Race == 2?1:0) * -0.3475) + ((Race == 3?1:0) * -0.0222) + (Diabetes * 0.3892) + (Smoker * 0.3717) + (Totalcholesterol * 0.0043) - (HDLcholesterol * 0.0114) + (On lipid-lowering medication * 0.1206) + (Systolic blood pressure * 0.0066) + (On hypertension medication * 0.2278) + (Family history of MI * 0.3239) + (ln(CAC + 1) * 0.2743)

10-year risk CAC = 100 * (1 - 0.99833e(Terms CAC))

 

 

Calculation Details and Variables

• Equation parameters such as Race, have two or more discrete values that may be used in the calculation. The numbers in the parentheses, e.g. (1), represent the values that will be used.
