[The significance of determination of Lp(a) in health examinations].
Lp(a), an independent risk factor of thrombotic and arteriosclerotic diseases, was determined in subjects undergoing health examinations, and the significance of the determination of Lp(a) in such examinations was investigated by studying its relation wih other risk factors for arteriosclerosis, etc. The subjects were 838 individuals. Lp(a) was determined by latex immunoassay (LIA). The mean Lp(a) value for all of the subjects was 10.9 +/- 7.2 mg/dl. Both gender groups were compared by age, but no significant changes were observed. In a study of Lp(a) in accordance with complications, there was no significant difference between the DM group and the non-DM group. There was also no significant difference between the IHD group and the non-IHD group. In the hyperlipemia group, the value of Lp(a) tender to be higher than in the non-hyperlipemia group. In the abnormal ECG group, the Lp(a) value was significantly higher than in the normal ECG group. When the relation between Lp(a) and other factors was studied, there was positive correlation with TC, beta Lp and LDLC, and a significant negative correlation with TRG. There was significant negative correlation with GOT, GPT and TTT. When the incidence of disease was compared by cut-off value, the incidence of abnormal ECGs was significantly higher at Lp(a) values of 25 mgdl or higher. In this study, Lp(a) showed positive correlations with TC, beta Lp and LDLC, the atherogenic risk of Lp(a) was evident. Because of the significant incidence of abnormal ECGs at the Lp(a) cut-off value of 25 mg/dl or higher, the risk range for Lp(a) should probably be considered as 25 mg/dl or higher.(ABSTRACT TRUNCATED AT 250 WORDS)
