The aim of the study was the assessment of selected inflammatory markers in patients with stable and unstable angina pectoris, in comparison to patients with dyslipidemia without coronary artery disease. The study group included 61 patients (37-79 years old), divided into three subgroups: group I. 26 (43%) with unstable angina, group 2. 19 (26%) with stable angina, group III. 16 (26%) dyslipidemia without coronary artery disease. We measured serum levels of cytokines (IL-1B, IL-1Ra, IL-2, IL-6, TNF-alpha), immunoglobulins (IgG, IgE, IgM), fibrinogen. C-reactive protein and subclass of lymphocytes T CD4 and T CD8. In stable and unstable angina pectoris group we found lower percentage of T CD4, T CD8 and higher level of TNF-alpha. In unstable angina group the level of IL-1 beta was lower and the concentration of C-reactive protein, IgE was higher in comparison to group without coronary artery disease. Observed immunoregulatory disorders confirm immune mechanism in the origin of unstable angina pectoris.

Variations of circulating C-reactive protein (CRP) levels are supposed to reflect chronic inflammatory process of the cardiovascular system. In particular, it has been reported that high-sensitivity CRP (hsCRP) is a promising marker of coronary heart disease. In the present study, we assessed the relationship between hsCRP and classic cardiovascular risk factors, such as age, blood pressure, smoking habit and serum lipids. Plasma hsCRP was measured by ELISA in 908 subjects, aged 30-79 years, who entered our health-check program. Plasma hsCRP level was 0.54+/-0.02 mg/l in 566 subjects without any disease currently treated. The level was significantly higher in patients treated for hypertension (0.74+/-0.06 mg/l, P=0.002), diabetes mellitus (0.77+/-0.09 mg/l, P=0.016) or coronary artery disease (0.99+/-0.16 mg/l, P=0.008) than in subjects without diseases. In a simple regression analyses of the 566 subjects without diseases, plasma hsCRP positively correlated with male gender, smoking, body mass index, systolic blood pressure, white blood cell count, blood hemoglobin, fasting blood glucose, serum gamma-GTP, uric acid and triglycerides, and inversely correlated with serum albumin and HDL-cholesterol. In multiple regression analysis, white blood cell count (r=0.276, P<0.001), body mass index (r=0.246, P<0.001), age (r=0.122, P=0.001) and smoking (r=0.112, P=0.009) showed independent correlations with plasma hsCRP. It is suggested that variation of circulating hsCRP, even within normal range, is involved in the interrelation of cardiovascular risk factors, such as age, smoking, obesity, high blood pressure and dyslipidemia, which are supposed to promote atherosclerosis and ultimately provoke cardiovascular diseases, such as coronary artery disease.

The simultaneous presence of various cardiovascular risk factors in the same individual is not rare, even in the pediatric age group. The clustering of risk factors can be termed insulin resistance syndrome (IRS) because of the putative central role of tissue insulin insensitivity in the background of the inter-related metabolic disturbances. Fasting hyperinsulinemia, impaired glucose tolerance, dyslipidemia, and hypertension are considered to represent the basic abnormalities of IRS. The most prevalent related disturbances are increased plasma levels of plasminogen activator inhibitor-1, fibrinogen, uric acid, homocysteine, and C-reactive protein, as well as visceral adiposity, microalbuminuria, disturbed essential fatty acid metabolism, low availability of lipid-soluble antioxidant vitamins, and enhanced expression of tumor necrosis factor-alpha in adipose tissues. Certain genetic abnormalities have been associated with IRS, but explain only a small part of the variability in insulin resistance. The exact prevalence of IRS in children remains to be defined; it was found to be 9% in one survey among children with obesity seeking medical attention. Modification of lifestyle, i.e. reduction of energy intake and enhancement of physical activity, are unquestionable prerequisites for long-term success in the management of IRS. In at least two randomized controlled studies, metformin proved to be clinically effective in increasing insulin sensitivity in hyperinsulinemic, nondiabetic adolescents. Thiazolidinediones have been successfully tested for the treatment of insulin resistance in adults, but not in children as yet. Prevention of the development of IRS in children is obviously of great significance for the health status of the community. However, the efficacy of various preventive approaches should be investigated further in carefully designed controlled trials.

Arteriosclerosis, atherosclerosis and vascular calcification are causally related to the high morbidity and mortality of patients with chronic renal failure. Oxidative stress and carbonyl stress of uremia, dialysis procedure and/or intravenous iron therapy result in AGE (advanced glycation end-product), ALE (advanced lipoxidation end-product) and AOPP (advanced oxidation protein product) formation, favouring together with elevated CRP (C-reactive protein) levels the development of cardiovascular and cerebrovascular complications. Enhanced plasma levels of homocysteine and ADMA (asymmetric dimethylarginine) contribute to this process. In addition, in chronic renal insufficiency hyperphosphatemia and an enhanced calcium x phosphorus ion product are associated with the morbidity and mortality of the patients, particularly in the presence of fetuin deficiency. Phosphorus, AGEs and AOPPs, beside other factors, catalyze the conversion of vascular smooth muscle cells to osteoblast--like cells (particularly in the presence of monocytes/macrophages), resulting in bone matrix protein formation. Other risk factors, such as age, male sex, smoking, hypertension, diabetes, chronic inflammation, insulin resistance or dyslipidemia (enhanced non-HDL-cholesterol) also contribute to the atherosclerotic risk profile of the patient with chronic renal insufficiency. While there is growing understanding of the mechanisms involved in arteriosclerosis, atherosclerosis and vascular calcification in uremia, we are still missing effective therapeutic maneuvers for reduction of excess mortality in uremic patients.

The recent focus on emerging cardiovascular risk factors, such as C-reactive protein, homocysteine, and small, dense low-density lipoprotein (LDL), may give the false impression that the current approach to the assessment of cardiovascular disease risk fails to identify a large section of the high-risk population. On the contrary, the new guidelines of the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) propose classifying an enormous number of individuals, including people with any form of atherosclerotic disease, diabetes, and a combination of major risk factors, into the category of high risk (>20% likelihood of a major coronary event or stroke in 10 years). Considering the widespread prevalence of the metabolic syndrome-a high-risk condition characterized by mild hypertension, mild dyslipidemia, hyperglycemia, and visceral obesity-we may be faced with the challenge of implementing aggressive risk reduction therapies in as much as 30% of the adult US population. From the point of view of risk assessment, a practical approach is to follow the NCEP guidelines (ie, place patients with diabetes and those with atherosclerotic complications in the highest risk category), apply the Framingham calculation to determine risk in people with common risk factors, and initiate early intervention in people who have familial hypercholesterolemia (LDL cholesterol >200 mg/dL) or a family history of early cardiovascular disease. The emerging risk factors may be useful for further stratifying risk in individuals with intermediate risk and the presence of risk factors not included in the Framingham calculation.

This study aimed to reveal the relationships among C-reactive protein (CRP), obesity, blood pressure (BP), and serum lipids in children. Eighty-six obese and 58 non-obese boys aged an average of 11.2 years were examined. Serum CRP levels were measured by high sensitivity latex turbidimetric immunoassay and subjects with CRP levels below 0.3 mg/dl were adopted. Comparisons of serum CRP levels, BP, and serum lipids levels between age-matched obese and non-obese groups were performed. A comparison of serum CRP levels among the percentage of relative weight quartiles and the relationships among percentage of relative weight, BP, and serum lipids in CRP quartiles were analyzed. The relationships between CRP and other parameters were analyzed by simple and stepwise multiple regressions. Obese children had significantly higher high-sensitivity CRP (hs-CRP) levels than their non-obese counterparts. The mean hs-CRP level was 5.5-fold higher in the top quartile of the percentage of relative weight than in the bottom quartile. In the top quartile of CRP, the percentage of relative weight, systolic BP, diastolic BP, pulse pressure, and low density/high density lipoprotein-cholesterol (LDL-C/HDL-C) were significantly higher than in the bottom quartile. The percentage of relative weight, BP, LDL-C, and apolipoprotein B (ApoB) showed positive correlations and HDL-C showed a negative correlation with log CRP by simple regression. Stepwise multiple regression analysis indicated that only the percentage of relative weight was strongly related to CRP. In conclusion, this study revealed a significant relationship between CRP and obesity in children. Obese children tended to have high CRP levels, BP elevation, and slight dyslipidemia. These results support the findings that CRP is one of the useful indices of childhood obesity that would affect the progression to future atherosclerotic disease. We consider that a strategy of preventing obesity from childhood would contribute to a drop in the future incidence of metabolic syndromes.

Heart disease is a major cause of morbidity and mortality among patients with renal failure. Premature atherosclerotic coronary heart disease is driven by multiple risk factors, including dyslipidemia and oxidative stress. In the nondialysis population, there is overwhelming evidence that treatment of dyslipidemia can significantly improve cardiovascular outcomes. Accumulating data indicate that dialysis patients have atherogenic lipid abnormalities. Although LDL cholesterol (LDL-C) levels in patients who undergo hemodialysis are normal or near normal, increased oxidized LDL-C, triglycerides, and lipoprotein (a) [Lp(a)]; decreased HDL cholesterol (HDL-C); and triglyceride-rich VLDL have been noted. Patients who receive peritoneal dialysis have a more atherogenic lipid profile with increased LDL-C, apolipoprotein B, oxidized LDL-C, triglycerides, and Lp(a) and decreased HDL-C. Furthermore, the LDL particles of peritoneal dialysis patients are small and dense. However, there is a dearth of information regarding the goals, efficacy, and safety of dyslipidemia treatment among dialysis patients. Given the strong evidence of risk reduction and the benefits of lipid-lowering treatment in the nondialysis population, the emerging consensus is that dialysis patients should be treated aggressively for dyslipidemia to an LDL-C goal below 100 mg/dl. Although physicians and patients may be reluctant to add medications because of concerns about polypharmacy, potential decreased compliance, and increased cost, the use of agents such as sevelamer that can serve multiple functions, including phosphate control, lipid lowering (decreased LDL-C and total cholesterol), and anti-inflammatory effects (decreased high-sensitivity C-reactive protein), should be explored and considered for patients who would benefit from such treatment.

Traditional risk factors for atherosclerosis are well known and their control decreases importantly the appearance of the disease. These factors are the genetic charge, dyslipidemia, smoking, systemic arterial hypertension, diabetes, obesity, gender, age, stress, estrogen levels in women, and life style. However, in the last decade, new risk factors have been identified especially for coronary and cerebrovascular atherosclerosis. Among these factors, the inflammatory process has been pointed out in which acute stage reactants participate, such as C-reactive protein, leukocyte count, globular sedimentation, multiple cytokines, alpha tumor necrosis factor, vascular and cellular adhesion molecules, some metalloproteinases, pregnancy-associated plasma protein A, lipoprotein-associated phospholipase A2, angiotensin II, and very probably infection. This article discusses the mechanism by which these markers participate in the atherosclerotic process and their value as predictors of future coronary events, as well as to what extent current therapeutics can contribute to decrease these events and to improve patient care.

Beyond the already well-established strong causative relationship with cancer, smoking increases the risk for vascular disease. Smoking may act directly or adversely influence risk factors contributing to the development of vascular disease. Smoking causes endothelial dysfunction, dyslipidemia (decreased high-density lipoprotein cholesterol levels, hypertriglyceridemia and increased oxidation of low-density lipoprotein cholesterol) and platelet activation leading to a prothrombotic state. Smoking increases emerging risk factors (eg, fibrinogen, homocysteine, and high-sensitivity C-reactive protein) and increases insulin resistance and the risk of developing type 2 diabetes mellitus. The beneficial effects of statins and antioxidants (eg, vitamins C and E, beta-carotene) are counteracted by smoking. Smoking-induced alterations in growth factors, adhesion molecules, and even in genes can accelerate the progression of atherosclerosis. The aim of this review is to consider the adverse consequences of smoking on the factors predisposing to vascular disease and to emphasize the beneficial effects of smoking cessation.

To investigate whether marked and sustained lipid-lowering in subjects with stable angina pectoris and dyslipidemia reduces exercise-induced myocardial ischemia, 17 subjects were treated with dose-adjusted atorvastatin over 1 year and underwent serial evaluation of exercise electrocardiographic ischemic parameters, serum biomarkers, and brachial artery endothelial function. Endothelial function improved progressively and C-reactive protein, P-selectin, and tissue plasminogen activator inhibitor levels decreased, but there was no decrease in exercise electrocardiographic ischemia.
