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)

As part of the DREsden CArdiovascular risk and Nutrition study, 2038 participants, selected from a cohort of 3076 workers in the Dresden area, underwent a detailed nutritional analysis of the periods before and after German reunification. Although protein, fat, carbohydrate, and total calorie intake did not change in Dresden after reunification, polyunsaturated fat replaced 17% of the saturated fatty acids, dairy product intake tripled, and fruit intake increased by 70%. Relative to a reference PROCAM 'western' cohort, the 90th percentile of triglycerides was higher in middle-aged men, and the levels of total cholesterol and HDLC were higher in all males. Serum LDLC levels in males and females were similar. Serum lipid concentrations and the prevalence of hyperlipidemia were similar to those of the PROCAM cohort, but smoking was less common. In young males and females, body mass index was higher; hypertension was more frequent. We assume that the differences in nutrition and risk profile before reunification were less substantial than commonly believed.

Differences in LDL and HDL subclass distribution contribute to increased CAD risk through a variety of mechanisms. The inherited disorder characterized by an abundance of small, dense LDL particles increased CAD risk 3-fold and is associated with rapid arteriographic progression. The metabolic milieu associated with the small LDL trait includes insulin resistance, increased IDL, increased susceptibility to oxidative damage, impaired reverse cholesterol transport, and increased post prandial lipemia. Recent evidence indicates that the LDL IIIa+b region are the LDL subclass regions most associated with atherosclerosis. Improvement in LDL subclass distribution has been associated with arteriographic improvement significantly more than LDLC change. Therapeutic treatments including diet, and many pharmacologic interventions have a differential response in subjects characterized by an abundance of either small, or large LDL particles. Individual patient information regarding LDL and HDL subclass distribution can be used to improve medical management of the CAD patient that results in improved outcomes.

Treatment with inhibitors of 3-hydroxyl-3-methylglutaryl coenzyme A reductase (statins) reduces the incidence of cardiovascular events, but it is unclear whether the beneficial effects are mediated solely by their lipid-lowering properties. We therefore investigated whether atorvastatin reduces inflammation and oxidative stress independently of its lipid-lowering effects. The subjects comprised 71 hyperlipidemic patients (64+/-9 years old, mean+/-SD) who were not receiving medical treatment. Serum lipid and C-reactive protein (CRP) levels, and urine 8-isoprostane level (an index of oxidative stress) were measured before and after 4 weeks of treatment with atorvastatin at 10 mg/day. In 38 patients, these biochemical variables and carotid intima-media thickness (IMT) were also measured after 6 months of treatment with atorvastatin. Atorvastatin markedly reduced CRP (from 0.69+/-0.36 to 0.42+/-0.20 and 0.35+/-0.19 mg/l, median+/-median absolute deviation, P<0.0001), 8-isoprostane (from 225+/-99 to 178+/-75 and 179+/-60 ng/g creatinine, P<0.05), and low density-lipoprotein cholesterol (LDLC; from 165+/-21 to 106+/-18 and 112+/-17 mg/dl, P<0.0001) after 4 weeks and 6 months of treatment, respectively. However, the reductions in CRP and 8-isoprostane were not correlated with those of LDLC. After 6 months of treatment, IMT was significantly decreased compared with the baseline value (from 0.94+/-0.26 to 0.90+/-0.20 mm, P<0.05), but this was not correlated with the reduction in LDLC. These results suggest that atorvastatin has beneficial effects on inflammation, oxidative stress, and the lipid profile in patients with hyperlipidemia. The extra-lipid effects are not attributable to the lipid-lowering effect of the statin, suggesting that the pleiotropic effects of atorvastatin are independent of its effects on the lipid profile.

Dyslipidemia represents one of the major risk factors for atherosclerosis affecting the arteries of large and medium caliber and consequently causing ischemia in the brain, heart, or legs. Coronary artery disease and cerebral stroke represent the major causes of morbidity and mortality among the elderly and middle aged subjects. The change of lifestyle can reduce the risk of cardiovascular disease but available drug therapy (in particular statins, inhibitors of 3-hydroxy-3-methylglutaryl coenzyme A reductase) is effective in modifying hyperlipidemia and consequently reducing cardiovascular events. The hypolipemic drugs can prevent, slow the progression and sometimes determine the regression of atherosclerotic plaques, therefore significantly reducing the clinical complications of atherosclerotic cardiovascular disease. In this review, we want to point out the role of the different lipoproteins, such as triglycerides, HDL-C, LDLC, Lp(a), in the pathogenesis of stroke and the role of statins in reducing both lipid fractions and stroke risk.
