Circulating HDL/Apolipoprotein A1 des Q243 Ratio Is Significantly Correlated with Coronary Artery Disease and Diabetes Mellitus

30 mg/dL, 23% had LDL-P concentrations less than 1001 nmol/L, 25% were between 1001 and 1299 nmol/L, and 52% of the subjects were greater than 1300 nmol/L. At low LDL-P concentration less than 1000 nmol/L, approximately 41% of the subjects had Lp (a) concentrations less than 30 mg/dL. Conclusions: These data demonstrate that many patients with normal Lp(a) levels of less than 30 mg/dL, had discordant elevation of LDL-P concentration, with 52% of them having LDL-P levels greater than 1300 nmol/L. These results suggest that many patients with low Lp(a) concentrations could retain significant residual atherogenic risk because of their high LDL-P levels.
