How to Calculate AIP From Triglyceride and HDL Levels

AIP refers to the atherogenic index of plasma and is calculated in an attempt to predict cardiovascular risk. AIP is based on the ratio of the values of triglycerides to high-density lipoprotein (HDL) levels. When placed into the scope of AIP, triglycerides and HDL refers to the relationship of atherogenic lipids to protective lipids. The AIP has demonstrated cardiovascular risk in clinical trials.

How to Calculate AIP From Triglyceride and HDL Levels

• 1

  Select the unit of measurement, either mmol/L or mg/dL. This will generally be based on the units that triglycerides and HDL were reported in. Units calculated in mmol/L refer to millimoles per liter. Units calculated in mg/dL refer milligrams per deciliter. To convert between the two, multiply mmol/L by 18 or divide mg/dL by 18.

• 2

  Calculate the AIP by taking the LOG base 10 of the value of triglycerides divided by the value of HDL: LOG (Triglycerides / HDL).

• 3

  Note that the value is less than 0.11 there is a low cardiovascular risk, between 0.11 to 0.21 there is an intermediate cardiovascular risk, and greater than 0.21 there is increased risk.
