In the patients with Lp(a) concentrations above the upper reference value of 480 mg/l there was a significant correlation between Lp(a) and the concentration of orosomucoid, erythrocyte sedimentation rate, and the platelet count. The plasma concentrations of cholesterol and high density lipoprotein-cholesterol in both male and female patients were significantly lower than in controls. Apolipoprotein B and apolipoprotein AI in the patients correlated significantly with total cholesterol and high density lipoprotein-cholesterol respectively. ER -
