🫀 Castelli Risk Index
Calculate the Castelli atherogenic risk indices (TC/HDL and LDL/HDL).
Castelli Risk Index
Total cholesterol (mg/dL)
HDL cholesterol (mg/dL)
LDL cholesterol (mg/dL)
When to use
Summarise the balance of atherogenic and protective cholesterol.
How it works
Castelli I = TC/HDL; Castelli II = LDL/HDL. Lower is better (TC/HDL ideally < 3.5).
Key points
- Complements absolute LDL and global risk scores.
- Higher ratios indicate greater atherogenic burden.
- Not a standalone treatment trigger.
