The effect of fish oil dietary supplementation on the dyslipidemia and coagulopathy of seven patients with nephrotic syndrome and hypoalbuminemia due to primary kidney disease was studied. Plasma lipids, platelet aggregation studies, simplate bleeding time, and fibrinogen levels were determined before and after 6 wk of treatment with fish oil (15 g/day of MaxEPA; 2.7 g of eicosapentenoic acid (EPA) and 1.8 g of docosahexenoic acid. Urea kinetics were determined from urine-urea concentration, urinary proteina, and urine volume. A 3-day dietary intake record was obtained from each patient before and after 6 wk of fish oil supplementation. There was no significant dietary change in protein, fat, or carbohydrate intake over the time period of the study. At study end, total triglycerides decreased from 2.98 +/- 1.31 to 2.18 +/- 1.14 mmol/L (P = 0.002), and very low-density lipoprotein-triglycerides decreased from 2.35 +/- 1.34 to 1.28 +/- 1.07 mmol/L (P = 0.01). Low-density lipoprotein (LDL) cholesterol increased from 5.18 +/- 1.74 to 7.35 +/- 2.83 mmol/L (P = 0.005). No significant changes occurred in bleeding time, platelet count, hematocrit, red blood cell flexibility, or whole blood viscosity. Platelet aggregation responses to collagen and arachidonic acid were consistently reduced after treatment, but there was no change in platelet response to ADP. The platelet membrane phospolipids showed a significantly increased incorporation of EPA after the fish oil diet (P = 0.03).(ABSTRACT TRUNCATED AT 250 WORDS)

During a transverse survey, 3 groups of men with the same weight and age were compared. Group I included 42 patients with coronary disease documented by coronarography, group 2 included 19 subjects with normal coronary angiograms, and group 3 included 27 healthy controls who had not undergone coronarography. Subjects presenting diabetes or any factor associated with secondary dyslipidemia or able to modify lipid levels were excluded from study. The following parameters were measured: total cholesterol (Chol), triglycerides (TG), HDL-cholesterol (HDL-C), LDL-cholesterol (LDL-C), apoprotein A1 (apoA1), apoprotein B (apoB), lipoprotein (a) or Lp(a), fibrinogen, insulinemia and plasminogen activator inhibitor activity (PAI). The levels of chol, LDL-C and ApoB were the same in the 3 groups. The levels of TG, HDL-C, apoA1 and the ApoA-1/APoB ratio were significantly different between groups 1 and 2, on the one hand, and groups 1 and 3, on the other hand. The levels of Lp(a) and insulin were similar in the 3 groups. Fibrinogen levels were slightly higher in group 1 than in group 3. There was no significant difference between groups 1 and 2 with regard to any of the parameters. Subjects with angiographically normal coronary arteries and subjects with documented coronary disease exhibited similar lipid abnormalities. In this study, TG, HDL-chol, apoA1 and the apoB ratio were better predictors of cardiovascular risk than Chol, LDL-C or apoB.

Epidemiologic research indicates that glucose intolerance and hypertension are interrelated phenomena, each powerfully predisposing to atherosclerotic cardiovascular disease. Both diabetic and hypertensive patients have greater amounts of atherogenic risk factors, including dyslipidemia, hyperuricemia, elevated fibrinogen, and left ventricular hypertrophy. Diabetic persons have an increased prevalence of hypertension (50%), and glucose intolerance is more common in hypertension (15% to 18%). Both share a strong relationship to excess weight, but the excess of hypertension in diabetic persons occurs in both lean and obese subjects. Diabetes doubles the risk of hypertension associated with overweight. The risk of coronary disease, stroke, and peripheral arterial disease increases with increasing blood pressure to the same degree in diabetic persons as in nondiabetic persons, but at any level of blood pressure, diabetic persons have a doubled risk of these outcomes. Both diabetic and hypertensive patients are particularly prone to silent or unrecognized myocardial infarctions. Greater efforts at primary prevention of both hypertension and diabetes are clearly needed, including efforts at weight control, exercise, limitation of salt intake, and control of blood lipid levels. In either diabetic or hypertensive candidates for cardiovascular disease, optimization of the chances of avoiding sequelae requires a comprehensive multifactorial approach. Prevention requires more than normalization of either the blood sugar or blood pressure. Rational preventive measures must also include weight reduction, a fat-modified diet, cessation of smoking cigarettes, raising high-density lipoprotein, lowering low-density lipoprotein, and reduction of fibrinogen. Hypertension, obesity, insulin resistance, hyperinsulinemia, hypertriglyceridemia, and low high-density lipoprotein cholesterol tend to coexist.(ABSTRACT TRUNCATED AT 250 WORDS)

Risk factors for primary cerebral hemorrhage remain uncertain. The population-based Stroke Registry of Dijon provides data on the risk factors. Among residents of Dijon (France), 130 cases of primary cerebral hemorrhage hospitalized from 1985 to 1992 were matched with 130 controls by age and sex. The following data were collected: history of hypertension, alcohol consumption, tobacco consumption, history of coagulation disorder, diabetes mellitus, dyslipidemia, and infectious disease in the 7 days before admission. The following parameters were measured on admission: blood pressure, blood glucose, cholesterol, triglycerides, hematocrit, fibrinogen, prothrombin levels, platelet counts, prothrombin time, bilirubin, transaminases, gamma-glutamyltransferase, and alkaline phosphatase. Electrocardiogram and Doppler ultrasound examination of cervical arteries were performed. Statistical analysis was performed by means of relative risk ratio for paired samples when dealing with proportions, and Student's t test for quantitative variables. A stepwise discriminant analysis was carried out to establish the relative weight of the different risk factors and their discriminant values. Among the qualitative data, the significant factors were history of hypertension, alcohol consumption, cardiac arrhythmia, atherosclerosis of carotid arteries and a previous infectious disease in the 7 days before admission. Among the quantitative data, the significant factors were early hypertension, high blood glucose levels, high hematocrit, and low cholesterol levels, in the acute stage of the stroke. After multifactorial analysis, only two factors were significant: hypertension and low cholesterol levels. Our population-based case-control study showed that hypertension and low cholesterol levels are the two discriminant risk factors for both lobar and basal ganglia primary cerebral hemorrhage. Therefore, treatment of hypercholesterolemia may increase risk of cerebral hemorrhage.

Hypertension is often related to metabolic disorders, such as android obesity, glucose intolerance, dyslipidemia, and hyperinsulinism (X syndrome). Insulin resistance (IR), described as the common link among these disorders, could contribute to an increase in coronary risk. The euglycemic insulin clamp technique has been used to show that different classes of antihypertensive agents have different effects on IR. The purpose of this multicenter study was to compare the effects of captopril to those of nicardipine on insulin profile using the oral glucose tolerance test (OGTT), a routine-feasible test. After a 1-month single-blind placebo period, 154 patients with hypertension and android obesity were randomized to 3 months of double-blind therapy with either 50 mg captopril twice daily (n = 77) or 50 mg nicardipine twice daily n = 77). An OGTT with an assay of insulin was performed before and after active treatment. Lipid parameters, Factor VII (F VII), fibrinogen, plasminogen activator inhibitor 1 (PAI-1), and insulin-like growth factor I (IGF-I) were measured at the same time. After 3 months of treatment, the changes from baseline in mean +/- SD values for the insulin area under the curve (AUC) were -24.8 +/- 107.4 microIU x h/mL (-15.2%) for captopril v 6.1 +/- 98.6 microIU x h/mL (4.8%) for nicardipine (P = .072). Changes in peak insulin values were -18.3 +/- 86.2 microIU/mL (-14%) for captopril v 6.7 +/- 79.4 microIU/mL (6.6%) for nicardipine (P = .070).(ABSTRACT TRUNCATED AT 250 WORDS)

There are a number of predisposing factors to thrombosis. Blood stasis and hypercoagulability are two important factors for the development of venous thrombosis. Several clinical situations are associated with these two factors. Congenital deficiencies in antithrombin III, protein C or protein S, the antiphospholipid antibodies represent well established risk factors. Arterial hypertension, dyslipidemia, tobacco, diabetes and obesity represent risk factors for arterial thrombosis. Hypofibrinolysis high levels fibrinogen and factor VII increases the risk of arterial thrombosis.

The obese state has been recognized to accentuate the known risk factors for atherosclerotic disease as dyslipidemia, hypertension, glucose intolerance and insulin resistance. Among other risk factors, obesity is characterized by a series of lipid disturbances, such as hypercholesterolemia, high fasting (and postprandial) triglyceride levels, low HDL cholesterol, high apolipoprotein B, high small dense lipoprotein particles and alterations of serum and tissue LPL-activity. Although obesity is associated with such cluster of lipid abnormalities, these factors do not explain the complete process of atherogenesis in the obese subject. Other risk factors belonging to the polymetabolic syndrome-cluster, insulin resistance, hypertension, fibrinogen, add substantial but not full explanation to the atherothrombotic process. Over the last decade, a series of excellent studies have provided the background for a more indepth mechanism of atherosclerosis; the role of lipid peroxidation in particular has been one of the focuses of this current research. There exists a lot of evidence suggesting a major role for oxidized LDL and VLDL particles in the pathogenesis of atherosclerosis. Although obesity is characterized by dyslipidemia, less is known about the oxidation capacity of lipoproteins in obese subjects. We measured the oxidizability in vitro in 21 premenopausal women and compared them to 18 age-matched controls. The oxidizability of the non-HDL fraction is evaluated by measuring the fluorescence and thiobarbituric acid reactive substances (TBARS: MDA nM/mg non-HDL) at different time intervals of incubation. TBARS formation increased linearly with the increase of lipids both in non-obese and obese subjects.(ABSTRACT TRUNCATED AT 250 WORDS)

Involuntary weight gains worsen all elements of the cardiovascular risk profile, including dyslipidemia, hypertension, insulin-resistant glucose intolerance, left-ventricular hypertrophy, hyperuricemia, and elevated fibrinogen. On the basis of data from the Framingham Heart Study and from other studies, it can be concluded that the degree of overweight is related to the rate of development of cardiovascular disease. After 26 y of follow-up in the Framingham study, each SD increment in relative weight was associated with 15% and 22% increases in cardiovascular events in men and women, respectively. Avoidance of weight gain after the age of 25 y is advisable to reduce cardiovascular mortality. There is a great potential benefit to weight loss, suggesting that weight control as a means for preventing and lessening cardiovascular disease become a national health priority. The optimal weight for avoidance of cardiovascular disease and prolonging life corresponds to a body mass index of 22.6 for men and 21.1 for women.

We investigated the relationships between hyperinsulinemia (a major indicator of the insulin resistance syndrome), blood pressure, dyslipidemia, and coagulation factors in 2606 community-dwelling Japanese individuals as part of the Jichi Medical School Cohort Study. An age-related decrease of the fasting insulin level was found in men but not in women. Body mass index, systolic and diastolic blood pressure, triglyceride and fasting glucose levels, and factor VII activity all increased in both sexes as the insulin level became higher, while the HDL cholesterol level decreased. In addition, total cholesterol and LDL cholesterol levels increased as the insulin level became higher and lipoprotein(a) levels decreased in the men. Fibrinogen levels were not related to the insulin level in either sex. Multiple logistic regression analysis revealed that fasting insulin levels were positively correlated with body mass index and fasting glucose and factor VII activity levels, whereas they were negatively correlated with HDL cholesterol in both sexes. In addition, fasting insulin levels were positively correlated with LDL cholesterol levels in men and with triglyceride levels in women. Our results indicate that hyperinsulinemia is associated with high factor VII activity in a general Japanese population as well as with high blood pressure and dyslipidemia. The accumulation of these cardiovascular risk factors in hyperinsulinemic subjects appears to contribute to cardiovascular events in the Japanese as well as in westerners.

Maintenance dialysis patients experience an exceedingly high incidence of arteriosclerotic cardiovascular disease (CVD) events that are poorly predicted by traditional CVD risk factor indices. We evaluated the prevalence of three non-traditional CVD risk factors, i.e. hyperhomocysteinemia, hyperfibrinogenemia, and lipoprotein (a) Lp(a)) excess, and combined hyperhomocysteinemia, hyperfibrinogenemia, and Lp(a) excess, in maintenance dialysis patients. Fasting total plasma homocysteine (Hcy), fibrinogen, Lp(a), glucose, and total and HDL cholesterol levels, and traditional CVD risk factor (i.e. glucose tolerance, smoking, hypertension, dyslipidemia) prevalences were assessed in 71 dialysis patients and 71 age, sex, and race matched Framingham Study controls free of clinical renal disease, with normal serum creatinine (< or = 1.5 mg/dl). Mean plasma Hcy 23.7 vs. 9.9 microM, P = 0.0001), fibrinogen (457 vs. 309 mg/dl, P = 0.0001), and Lp(a) (30 vs. 17 mg/dl, P = 0.0070) levels were substantially increased in the dialysis patients. Matched odds ratios (with 95% confidence intervals), dialysis patients/controls, for hyperhomocysteinemia, hyperfibrinogenemia, and Lp(a) excess, alone or combined, were markedly greater in the dialysis patients, with no evidence of confounding by the traditional CVD risk factors: hyperhomocysteinemia, 105.0 (29.9-368.9); hyperfibrinogenemia, 16.6 (6.6-42.0); Lp(a) excess, 3.5 (1.5-8.4); all three combined 35.0 (5.7-199.8). Given in vitro evidence that Hcy, Lp(a), and fibrinogen interact to promote atherothrombosis, combined hyperhomocysteinemia, hyperfibrinogenemia, and Lp(a) excess may contribute to the high incidence of vascular disease sequelae experienced by dialysis patients, which is inadequately explained by traditional CVD risk factors. Controlled, prospective studies of well-characterized maintenance dialysis cohorts are urgently required to substantiate this hypothesis.
