This former standalone HDL page has been folded into ASCVD / Lp(a) Prevention Master. It remains as a short preserved pointer for the key rule that high HDL does not neutralize Lp(a) risk.

This page is no longer an active standalone owner. Its useful HDL U-curve thresholds and “HDL does not offset Lp(a)” rule were folded into ASCVD / Lp(a) Prevention Master on 2026-05-10.
Preserved core rule: the old HDL peak of 2.53 mmol/L is worth remembering, but the latest HDL around 1.99 mmol/L downgrades extreme-HDL concern. Revisit deeper HDL workup only if HDL repeatedly returns to >2.3-2.6 mmol/L or imaging shows discordant disease. Good HDL never cancels Lp(a), smoking, BP, or plaque uncertainty.
