Abstract

We examined the serum lipids, apoproteins and lipoproteins, and several neutral sterols including cholestanol, desmosterol, lathosterol, campesterol and β-sitosterol in 45 male patients with coronary artery disease (CAD) and 40 normal control male subjects. The results were as follows:(1) Statistically significant differences between both groups were noted in triglycerides, high density lipoprotein cholesterol (HDL-Ch), low density lipoprotein cholesterol (LDL-Ch), β-lipoprotein (β-Lipo), apolipoprotein (Apo) A-I, Apo A-II, Apo B, β-Lipo/HDL-Ch, Apo B/Apo A-I, HDL-Ch/total cholesterol, and Atherogenic index, as reported previously.(2) Serum Lp (a) levels were significantly higher (p<0.001) in the CAD group (162.0±120.7mg/l) than in the control group (76.0±64.1mg/l).(3) No significant differences between both groups were noted in plant sterols (campesterol and β-sitosterol) and desmosterol. While, serum cholestanol, which was an intermediate metabolite in the cholesterol metabolic pathway, and lathosterol, which has been reported to be a good indicator of whole-body cholesterol synthesis, were significantly high in the CAD group.These results showed that patients with CAD had multiple risk factors in the metabolism of lipids, particularly of cholesterol, and lipoproteins.
