C-reactive protein (CRP) has been suggested to exert direct adverse effects on the vasculature in experimental setups, including endothelial dysfunction and proinflammatory changes. Here, we assessed the consequences of 1.25 mg/kg highly purified recombinant human CRP, administered as an intravenous bolus, in six patients with familial hypercholesterolemia (FH) and six normocholesterolemic subj...

The aim of the present study was to investigate if hyperlipidemia interferes with the infarct size-limiting effect of postconditioning and to study the involvement of peroxynitrite in this phenomenon. Rats were fed a 2% cholesterol-enriched or normal diet for 12 wk. Infarct size by triphenyltetrazolium chloride staining was measured in hearts isolated from both groups and subjected to 30 min co...

Dyslipidemia appears to be a conventional risk factor for acute myocardial infarction (AMI). Several studies have reported decreased levels of antioxidants and increased levels of ischemia-modified albumin (IscMA) and lipid peroxides in dyslipidemic myocardial infarct patients. However, literature search reveals no reports of normolipidemic AMI patients with reference to antioxidants and IscMA ...

BACKGROUND Hyperlipidemic factors contribute to the high cardiovascular risk in hemodialysis patients. Soy protein has decreased some atherogenic lipid concentrations in subjects with normal renal function. This study evaluates the effect of soy protein on serum lipid profiles in hyperlipidemic and normolipidemic hemodialysis patients. METHODS Nineteen hyperlipidemic and 18 normolipidemic hem...

To see whether there are any lipoprotein abnormalities in diabetic patients without hyperlipidemia, lipoprotein composition was examined in 75 strictly normolipidemic diabetic patients. Their plasma cholesterol (chol) and triglyceride (TG) were limited to less than 6.0 and less than 1.7 mM, respectively. Body-weight- and age-adjusted normolipidemic healthy subjects served as the control group. ...

Apolipoprotein E (apoE) is important in modulating the catabolism of remnants of triglyceride-rich lipoprotein particles. It is a polymorphic protein with the three common alleles coding for apoE2, apoE3, and apoE4. ApoE3 is considered the normal isoform, while apoE4 is associated both with hypercholesterolemia and type V hyperlipoproteinemia. We quantitated the kinetics of metabolism of apoE4 ...

Background. Menopause, a form of reproductive aging, is marked by many hormonal variations which cause imbalance in the oxidative processes resulting in onset of endothelial dysfunction leading to cardiovascular disease (CVD). We aimed to analyze the effect of oxidative stress in an early detection of CVD in all menopausal women both normolipidemic and hyperlipidemic. Methods and Results. Study...

BACKGROUND Apoptosis of vascular endothelial cells (ECs) can be induced in vitro by experimentally modified LDL. Description of proapoptotic circulating lipoproteins may significantly enhance understanding of atherothrombosis pathophysiology. METHODS AND RESULTS Fast protein liquid chromatography of LDL samples from 7 asymptomatic, hypercholesterolemic patients yielded subfractions L1-L5 in i...

BACKGROUND C-Reactive protein (CRP) has been shown to be a strong predictor of coronary heart disease (CHD) and is being considered in cardiovascular disease risk assessment. The number of normolipidemic individuals who are eligible for evaluation of CRP in overall CHD risk assessment is not known. METHODS We analyzed data from the National Health and Nutrition Examination Survey 1999-2000 an...
