In order to ascertain the most effective index for predicting coronary sclerosis, the concentration of lipids, lipoproteins, and apoproteins in serum were determined in 45 males aged over 44 with angiographically diagnosed effort angina and in 153 male controls aged over 44 without ischemic heart disease (IHD) on physical examination. The results of our study are summarized as follows. 1) Alcohol intake of 25 g/day or more and smoking of 20 cigarettes/day or more showed significant odds ratios of 0.47 and 2.33, respectively. 2) By decrease of 10 mg/dl in HDLC level or of 10 mg/dl in Apo-AI level, the possibility of coronary sclerosis increases twofold after adjusting the effects of confounders. 3) LDLC/HDLC and Apo-B/Apo-AI are effective indices for predicting coronary sclerosis and, in particular, the probability of coronary sclerosis increases 3.8 times by increase of 0.5 in Apo-B/Apo-AI.

The relationship of dyslipidemia, particularly hypercholesterolemia to coronary heart disease is now well established. Although ischemic heart disease and stroke share many of the same risk factors, the relationship of cholesterol to stroke remains controversial. The 6-year and 12-year follow-up of the MRFIT study showed that elevated cholesterol significantly increased the risk for fatal nonhemorrhagic stroke. Atkins found no evidence that lowering plasma cholesterol influenced the incidence of fatal or nonfatal stroke and regression analysis showed no statistical association between the magnitude of cholesterol reduction and the risk for fatal stroke. We cannot preclude the possibility that more effective cholesterol lowering over a longer period of time might be effective. Hypertension is the most powerful risk factor for stroke. The San Antonio Heart Study reported a clustering of cardiovascular risk factors in individuals who developed hypertension during an eight-year follow-up period (higher levels of BP, fasting TC and LDLC, TG, glucose and insulin, and BMI, less favourable fat deposition, and lower HDL). Insulin resistance may be the unifying factor that results in those phenomena, the so-called syndrome X. The important factor underlying syndrome X may be central or visceral obesity, suggesting that maintenance or attainment of ideal weight would be a powerful preventive factor against both CHD and nonhemorrhagic stroke. There is evidence from the Treatment of Mild Hypertension Study that nutritional/hygienic measures can reduce the syndrome X risk factors and hence the risk of coronary heart disease and stroke.

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)

We describe the pattern of change for serum lipids and apolipoproteins from 1 to 15 years of age in a cohort of 128 children, supplemented with 215 children from 11 years of age and 243 at 13 years of age. Total cholesterol (TC) decreased after infancy, increased in early puberty and then decreased to 15 years of age. Reciprocal changes in high (HDLC) and low (LDLC) density lipoprotein cholesterol occurred during each interval, with HDLC increasing from 13 to 15 years in both sexes. The correlation for TC between children of both sexes and mothers and fathers varied from 0.1 to 0.28 at 2-13 years. At 15 years of age the correlation between mothers: daughters increased to 0.31, decreased to 0.19 for fathers: daughters, but no association was present between either parent and their sons. There were no differences in mean lipid values for the sample grouped according to the extent of family history of early ischaemic heart disease (before 60 years of age). There were few significant associations between serum lipids, energy and nutrients. At 15 years of age inverse associations were present between TC and energy, protein, sugar, starch and fibre intakes, and a positive association with total fat intake.
