Haptoglobin Levels and Phenotype as Determinants of Cardiovascular Risk in Type 2 Diabetes: Insights from the FIELD Sub-study

By MedXY 02/04/2026

This FIELD sub-study reveals that while Haptoglobin 1-1 phenotype combined with low HP levels indicates the lowest CVD risk in Type 2 Diabetes, higher HP levels significantly increase risk, particularly within the HP 1-1 group. Fenofibrate benefits appear independent of HP status.
