Serum lipoproteins and apolipoproteins A I and A II in male patients with peripheral arterial insufficiency.

Serum apolipoprotein A I and A II concentrations and triglyceride and cholesterol concentrations in serum lipoprotein density classes were determined in male patients with peripheral arterial insufficiency (PAI) and in controls. Both triglyceride and cholesterol concentrations in serum, very low and low density lipoproteins were higher in PAI patients than in controls. The cholesterol in high-density lipoproteins and the serum apolipoprotein A I concentration were lower in PAI patients than in controls. No difference between the groups was found for serum apolipoprotein A II concentration. The results show that the lipoprotein pattern in PAI is changed in roughly the same way as in ischemic heart disease.
