The 'midband' lipoprotein is a coronary risk factor in Japanese patients with familial hypercholesterolaemia.
The relationship between coronary stenosis and 'midband' lipoprotein, which was observed between low density lipoproteins and very low density lipoproteins by 3% polyacrylamide gel electrophoresis, was studied in patients with heterozygous familial hypercholesterolaemia (FH). The subjects were 46 patients with FH, who were evaluated by coronary angiography. The groups with and without coronary artery disease (CAD) were compared. Age, sex ratio, total cholesterol, triglyceride, HDL-cholesterol and lipoprotein(a) levels were matched in these two groups. In addition, Achilles tendon thickness and the incidence of risk factors such as diabetes mellitus, hypertension and smoking between these two groups were matched. Under these conditions, the frequency of midband was higher in the patients with CAD (20/26) than that in patients without (4/20). The results suggest that the presence of a midband among Japanese is an independent risk factor for coronary stenosis even in cases of FH who have severe hypercholesterolaemia.
