Lipid-lowering therapy response calculator

Estimates the expected LDL-C at 3 months after a treatment change by back-calculating the untreated baseline LDL from the current regimen and applying the multiplicative reduction of the new regimen.

Method: LDLbaseline = LDLcurrent / (1 − rcurrent) · LDLpredicted = LDLbaseline × (1 − rnew) · For combinations: rtotal = 1 − Π(1 − ri) · Reduction values from Law meta-analysis (BMJ 2003), ESC 2021 and PCSK9/inclisiran trials.

Current treatment Starting point

Regimen the patient is taking when the current LDL-C is measured.

Estimated combined reduction 49%

Proposed treatment New regimen

Regimen to be started — predicted LDL is calculated at 8–12 weeks.

Estimated combined reduction 55%
