Abstract
INTRODUCTION Coronary Artery Disease (CAD) is a prevalent condition characterized by the presence of atherosclerotic plaques in the coronary arteries of the heart. The global burden of CAD has increased significantly over the years, resulting in millions of deaths annually and making it the leading health-care expenditure and cause of mortality in developed countries. The lack of cost-effective strategies for monitoring the prognosis of CAD warrants a pressing need for accurate and efficient markers to assess disease severity and progression for both reducing health-care costs and improving patient outcomes. AREA COVERED To effectively monitor CAD, prognostic biomarkers and imaging techniques play a vital role in risk-stratified patients during acute treatment and over time. However, with over 1,000 potential markers of interest, it is crucial to identify the key markers with substantial utility in monitoring CAD progression and evaluating therapeutic interventions. This review focuses on identifying and highlighting the most relevant markers for monitoring CAD prognosis and disease severity. We searched for relevant literature using PubMed and Google Scholar. EXPERT OPINION By utilizing the markers discussed, health-care providers can improve patient care, optimize treatment plans, and ultimately reduce health-care costs associated with CAD management.

Abstract
Fifty percent of all death from cardiovascular diseases is due to coronary artery disease (CAD). This is avoidable if early identification is made. Preventive health care has a major role in the fight against CAD. Atherosclerosis and atherosclerotic plaque rupture are involved in the development of CAD. Modifiable risk factors for CAD are dyslipidemia, diabetes, hypertension, cigarette smoking, obesity, chronic renal disease, chronic infection, high C-reactive protein, and hyperhomocysteinemia. CAD can be prevented by modification of risk factors. This paper defines the primary, secondary, and tertiary prevention of CAD. It discusses the mechanism of risk factor-induced atherosclerosis. This paper describes the CAD risk score and its use in the selection of individuals for primary prevention of CAD. Guidelines for primary, secondary, and tertiary prevention of CAD have been described. Modification of risk factors and use of guidelines for prevention of CAD would prevent, regress, and slow down the progression of CAD, improve the quality of life of patient, and reduce the health care cost.

Targeted anti-inflammatory therapy is a new insight for reducing cardiovascular events: A review from physiology to the clinic. Life Sci 2020; 253:117720. [PMID: 32360620 DOI: 10.1016/j.lfs.2020.117720] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2020] [Revised: 04/13/2020] [Accepted: 04/14/2020] [Indexed: 12/30/2022]
Abstract
Despite considerable progressions, cardiovascular disease (CVD) is still one of the major causes of mortality around the world, indicates an important and unmet clinical need. Recently, extensive studies have been performed on the role of inflammatory factors as either a major or surrogate factor in the pathophysiology of CVD. Epidemiological observations suggest the theory of the role of inflammatory mediators in the development of cardiovascular events. This may support the idea that targeted anti-inflammatory therapies, on the background of traditional validated medical therapies, can play a significant role in prevention and even reduction of cardiovascular disorders. Many randomized controlled trials have shown that drugs commonly useful for primary and secondary prevention of CVD have an anti-inflammatory mechanism. Further, many anti-inflammatory drugs are being examined because of their potential to reduce the risk of cardiovascular problems. In this study, we review the process of inflammation in the development of cardiovascular events, both in vivo and clinical evidence in immunotherapy for CVD.

Abstract
Objective The aim of the study was to establish, by means of linear regressions analysis, whether RANTES and CCL2 have a relationship with age, sex, heart rate, ejection fraction, white blood cells count, monocyte count, platelet count, mean platelet volume, hsCRP concentration, creatinine and eGFR value, applied treatments, and coronary risk factors in polish cardiovascular disease patients. Methods Plasma chemokines concentrations were measured by ELISA method (R&D Systems Europe Ltd., Abingdon, England) in 115 cardiovascular disease patients (83 myocardial infarction/AMI and 32 stable angina/SA) and in the control group (N=25). Results Univariate linear regression analysis found that (1) for men mean RANTES plasma level is 1.56 times higher as compared to women; (2) if patient's age increases by 1 year, the mean RANTES concentration value increases by 1.4%; (3) if CCL2 concentration increases by 10 pg/mL, the mean RANTES concentration value increases by 3.3%; (4) if hsCRP concentration increases by 1 mg/L, the mean RANTES concentration value increases by 1.0%. By means of multiple linear regression analysis we found that (1) for men the mean plasma RANTES concentration value increases 1.89 times as compared to women; (2) if CCL2 concentration increases by 10 pg/mL, the mean RANTES concentration value increases by 3.4%; (3) if MPV increases by 1 fL, the mean RANTES concentration value increases by 12%, if other model parameters are fixed. For CCL2 we did not obtain statistically significant linear regression models. Conclusion Due to high variability of obtained CCL2 concentrations, it seems that RANTES better reflects the presence of the atherosclerotic lesion than CCL2. RANTES as a marker of atherosclerotic process may be an important therapeutic target, and the assessment of RANTES concentration should be interpreted depending on patient's sex, age, platelet hyperactivity state, hsCRP, and CCL2 concentration.

Significant association between admission serum monocyte chemoattractant protein-1 and early changes in myocardial function in patients with first ST-segment elevation myocardial infarction after primary percutaneous coronary intervention.

Abstract
Background Recent studies have indicated that monocyte chemoattractant protein-1 (MCP-1) plays an important role in the initiation and progression of ischaemic heart disease. However, no previous research has investigated the correlation between serum MCP-1 levels and early changes in myocardial function in patients with ST-segmental elevation myocardial infarction (STEMI) after primary percutaneous coronary intervention (PCI). Methods A total of 87 STEMI patients who had undergone a successful primary PCI were consecutively recruited. All the patients included in this study were grouped into two subgroups according to the median value of MCP-1 upon admission. An early change in left ventricular ejection fraction (LVEF) was defined as (LVEF at 3 months post-STEMI)-(LVEF at 2 days post-STEMI). Results Serum MCP-1 levels increased gradually over time during the first 72 h after the onset of STEMI. The concentration of hypersensitive cardiac troponin I (hs-cTnI) upon admission as well as at 24 h and 72 h after primary PCI, especially the peak hs-cTnI concentration, declined significantly in the low admission MCP-1 group. As continuous variable, admission MCP-1 also correlated positively with admission hs-cTnI, hs-cTnI at 24 h after primary PCI, and peak hs-cTnI. Additionally, the absolute early change in LVEF improved markedly in the low admission MCP-1 group (3.77% ± 6.05% vs − 0.18% ± 7.69%, p = 0.009) compared to that in the high admission MCP-1 group. Most importantly, the global LVEF in the low admission MCP-1 group also improved significantly at 3 months compared to baseline LVEF (55.79% ± 7.05% vs 59.60% ± 6.51%, p = 0.011), while an improvement in global LVEF was not observed in the high admission MCP-1 group. Furthermore, as a continuous variable, the MCP-1 level up admission also correlated negatively with early changes in LVEF (r = − 0.391, p = 0.001). After assessment by multiple linear regression analysis, the MCP-1 level upon admission remained correlated with early changes in LVEF [beta = − 0.089, 95% CI (− 0.163 to − 0.015), p = 0.020]. Conclusion MCP-1 upon admission not only correlated positively with hs-cTnI at different time points and peak hs-cTnI, but also associated inversely with early improvements in myocardial function in patients with first STEMI. So we speculated that suppression the expression of MCP-1 via various ways may be a promising therapeutic target in myocardial I/R injury in the future.

Abstract
BACKGROUND The aim of this study was to investigate the expression of monocyte chemoattractant protein-1 (MCP-1) and its correlation with the blood lipid level in upper gastrointestinal bleeding (UGIB). MATERIAL AND METHODS A total of 118 patients with UGIB were enrolled in this study. The relevant indicators for blood lipid levels were detected using a biochemical analyzer. MCP-1 levels in the serum of patients was determined through enzyme-linked immunosorbent assay (ELISA). Statistical Product and Service Solutions (SPSS) 17.0 software was used for the statistical analysis. Two-sample t-test was used for the intergroup comparison. The significant indicators were included in a multivariate logistic regression model to analyze the prognostic factors of UGIB. Pearson analysis was applied to the correlation analysis. P<0.05 suggested that the difference was statistically significant. RESULTS MCP-1 expression levels in patients with UGIB were significantly lower than that in the control group and were even further reduced in patients with massive hemorrhage. The levels of total cholesterol (TC), triglyceride (TG), and low-density lipoprotein (LDL) in the serum of patients with UGIB were decreased compared with those in the control group and these indicators of the blood lipid level were decreased much more in patients with massive hemorrhage. The MCP-1 expression was positively correlated with the levels of TC, TG, and LDL in serum. MCP-1 and TC were the prognostic influencing factors of UGIB. CONCLUSIONS Serum MCP-1 expression was significantly decreased in patients with UGIB and correlated with blood lipid level, suggesting it might be a prognostic factor for UGB.

Abstract
Stroke is the third leading cause of mortality. Approximately 80 to 85% strokes are ischemic due to carotid artery stenosis (CAS). The prevalence of significant CAS is 7% in women and 9% in men. Severe asymptomatic CAS varies from 0 to 3.1%. Prevalence of symptomatic CAS is high in patients with peripheral arterial disease. CAS is due to atherosclerosis, the major risk factors for which include dyslipidemia, hypertension, diabetes, obesity, cigarette smoking, advanced glycation end products (AGEs) and its receptors (RAGE, soluble RAGE [sRAGE]), lack of exercise and C-reactive protein (CRP). This article discusses the basic mechanism of atherosclerosis and the mechanisms by which these risk factors induce atherosclerosis. The role of AGEs and its receptors in the development and progression of CAS has been discussed in detail. Lifestyle changes and medical treatment of CAS such as lifestyle changes, lipid-lowering agents, antihypertensive agents, antidiabetic drugs, anti-AGE therapy, measures to elevate soluble receptors of AGE (sRAGE, esRAGE). CRP-lowering agents have been discussed in detail. The drugs especially lipid-lowering agents, and antihypertensive and antidiabetic drugs suppress, regress, and slow the progression of CAS. The possible role of lowering the levels of AGEs and raising the levels of sRAGE in the treatment of CAS has been proposed. Lifestyle changes besides medical treatment have been stressed. Lifestyle changes and medical treatment not only would slow the progression of CAS but would also regress the CAS.

Abstract
PURPOSE OF REVIEW The varied effects of colony-stimulating factors (CSFs) on monocytes and macrophages during inflammation and atherosclerosis and its clinical presentation prompt the question whether the differing effects of CSFs dictate macrophage function and disease progression. RECENT FINDINGS CSFs can give rise to heterogeneous populations of monocyte-derived macrophages that are characterized by disparate expression of distinct molecules which dictate their ability to process lipid and regulate inflammatory and immune responses. The CSFs have been found within atherosclerotic plaques and in the circulation where their levels may act as predictive biomarkers of disease progression. Accordingly, differing exposure to these factors imparts divergent genomic signatures and functional properties on macrophages and may impact the multifactorial steps involved in atherogenesis, plaque progression and instability. SUMMARY Great interest in macrophage heterogeneity in the genesis and progression of atherosclerosis has led to the search for consistent markers of specific subsets in both animal models and humans. A better understanding of the overlap and competition between CSF regulation of macrophage phenotypes is therefore warranted, to allow their characterization in plaques. Subsequent targeted genetic and pharmacological intervention will facilitate the generation of therapeutic approaches to halt the progression and rupture of advanced atherosclerotic plaques.

Impact of macrophage inflammatory protein-1α deficiency on atherosclerotic lesion formation, hepatic steatosis, and adipose tissue expansion. PLoS One 2012; 7:e31508.

Abstract
Macrophage inflammatory protein-1α (CCL3) plays a well-known role in infectious and viral diseases; however, its contribution to atherosclerotic lesion formation and lipid metabolism has not been determined. Low density lipoprotein receptor deficient (LDLR−/−) mice were transplanted with bone marrow from CCL3−/− or C57BL/6 wild type donors. After 6 and 12 weeks on western diet (WD), recipients of CCL3−/− marrow demonstrated lower plasma cholesterol and triglyceride concentrations compared to recipients of C57BL/6 marrow. Atherosclerotic lesion area was significantly lower in female CCL3−/− recipients after 6 weeks and in male CCL3−/− recipients after 12 weeks of WD feeding (P<0.05). Surprisingly, male CCL3−/− recipients had a 50% decrease in adipose tissue mass after WD-feeding, and plasma insulin, and leptin levels were also significantly lower. These results were specific to CCL3, as LDLR−/− recipients of monocyte chemoattractant protein−/− (CCL2) marrow were not protected from the metabolic consequences of high fat feeding. Despite these improvements in LDLR−/− recipients of CCL3−/− marrow in the bone marrow transplantation (BMT) model, double knockout mice, globally deficient in both proteins, did not have decreased body weight, plasma lipids, or atherosclerosis compared with LDLR−/− controls. Finally, there were no differences in myeloid progenitors or leukocyte populations, indicating that changes in body weight and plasma lipids in CCL3−/− recipients was not due to differences in hematopoiesis. Taken together, these data implicate a role for CCL3 in lipid metabolism in hyperlipidemic mice following hematopoietic reconstitution.

Abstract
OBJECTIVE Monocyte chemoattractant protein-1 (MCP-1/CCL2) is a chemokine involved into the pathogenesis of atherosclerosis and has prognostic value in the acute and chronic phases in patients with acute coronary syndromes. RESEARCH DESIGN AND METHODS MCP-1/CCL2 concentration was measured in plasma fractions of 363 middle-aged overweight/obese individuals (aged 61 +/- 12 years, BMI 30.1 +/- 6.6 kg/m(2), 15% with type 2 diabetes, and 12% with impaired glucose tolerance) of a population survey carried out in 1990-1991 in Lombardy, Italy (Cremona Study), and cardiovascular disease (CVD) mortality was assessed in 2006 through Regional Health Registry files. RESULTS At baseline MCP-1/CCL2 was increased in individuals with type 2 diabetes (P < 0.05) and showed significant correlations with biochemical risk markers of atherosclerosis. After 15 years, among the 363 subjects, there were 82 deaths due to CVD. In univariate analysis age, sex, fasting glucose and insulin, fibrinogen, glucose tolerance status, smoking habit, and MCP-1/CCL2 were associated with CVD mortality. Age, sex, fasting serum glucose, MCP-1/CCL2, and smoking habit maintained an independent association with CVD mortality in multiple regression analysis. In a subgroup of 113 subjects in whom data for C-reactive protein (CRP) were available, its level was not predictive of CVD mortality. CONCLUSIONS In middle-aged overweight/obese individuals MCP-1/CCL2 was independently associated with CVD mortality. Further studies will be necessary to establish its role as a surrogate biomarker and as a potential therapeutic target.

Abstract
Angiotensin II receptor blockade has been shown to have a beneficial effect on the angiopathies of hypertension and hyperglycemia in patients with type 2 diabetes. However, the effect of angiotensin II receptor blockade on monocyte and endothelial cell adhesion markers in type 2 diabetes is poorly understood. We investigated the effects of valsartan on these markers in 53 hypertensive patients with and without type 2 diabetes mellitus. Levels of monocyte activation markers (soluble CD14: 2.1+/-0.9 vs. 3.3+/-1.4 microg/ml, p<0.01; monocyte chemotactic peptide: 392+/-94 vs. 489+/-114 pg/ml, p<0.05; and monocyte-derived microparticles: 264+/-98 vs. 511+/-128/microL, p<0.01) and endothelial cell activation markers (soluble E-selectin: 41+/-11 vs. 61+/-20 ng/ml, p<0.001; and soluble vascular cell adhesion molecule-1: 478+/-82 vs. 584+/-101 ng/ml, p<0.01) were significantly increased in hypertensive patients with type 2 diabetes compared to normotensive controls. In addition, the concentrations of adiponectin were significantly decreased in patients with type 2 diabetes (8.1+/-3.1 vs. 5.2+/-2.5 microg/ml, p<0.01). Regardless of the presence of diabetic complications, both systolic and diastolic blood pressures significantly decreased after valsartan administration (valsartan 80 mg/day for 8 weeks). Monocyte and endothelial cell activation markers were decreased significantly in patients with type 2 diabetes after valsartan treatment, but not in non-type 2 diabetic patients. In addition, valsartan alleviated hypoadiponectinemia in hypertensive patients with diabetes (before vs. after: 5.2+/-2.5 vs. 7.6+/-2.7 microg/ml, p<0.001) but did not increase adiponectin levels in the non-diabetic hypertensive group, for which the average adiponectin level was normal prior to treatment. These results suggest angiotensin II receptor blockade (valsartan) may be beneficial as an anti-atherosclerotic therapy in patients with type 2 diabetes in addition to its anti-hypertensive action.

Abstract
Because the prevalence of obesity has increased dramatically in recent years, one of the key targets of public health is obesity and its associated pathological conditions. Obesity occurs as a result of white adipose tissue enlargement, caused by adipocyte hyperplasia and/or hypertrophy. Recently, endocrine aspects of adipose tissue have become an active research area and these adipose tissue-derived factors are referred to as adipokines. These adipokines interact with a range of processes in many different organ systems and influence a various systemic phenomena. Therefore, dysregulated production of adipokines has been found to participate in the development of metabolic and vascular diseases related to obesity. The obese state is also known to be associated with increased local and systemic inflammation. Adipokines influence not only systemic insulin resistance and have pathophysiological roles in the metabolic syndrome and cardiovascular disease, but also contribute toward an increase in local and systemic inflammation. Thus, circulating levels of adipokines can be used as high-throughput biomarkers to assess the obesity-related health problems, including low grade inflammation. This review focuses on the usefulness of measuring circulating adipokine levels for the assessment of obesity-related health problems.

Abstract
BACKGROUND Neutrophils, in concert with proinflammatory cytokines, play an important role in the progression of atherosclerosis. Calcium channel blockers are commonly used in the treatment of hypertension, and their pleiotropic effects, other than the lowering of blood pressure, have been recently recognized. METHODS We studied the effects of various calcium channel blockers (amlodipine, nicardipine, cilnidipine, benidipine, efonidipine, nifedipine, azelnidipine, verapamil, and diltiazem; each being used at 5 and 10 micromol/l) on superoxide (O(2)(-)) release, migration, and signaling pathways in human neutrophils stimulated by granulocyte-macrophage colony-stimulating factor (GM-CSF) or tumor necrosis factor-alpha (TNF-alpha). RESULTS GM-CSF-induced O(2)(-) release was suppressed by amlodipine, nicardipine, and cilnidipine, whereas TNF-alpha-induced O(2)(-) release was suppressed by amlodipine, nicardipine, cilnidipine, benidipine, efonidipine, nifedipine, and azelnidipine. TNF-alpha-induced phosphorylation of extracellular signal-regulated kinase (ERK) and Akt, but not p38 mitogen-activated protein kinase (MAPK), was attenuated by nicardipine, cilnidipine, benidipine, efonidipine, and azelnidipine. By contrast, GM-CSF-induced phosphorylation of ERK, p38, and Akt was affected by none of the blockers. GM-CSF-induced neutrophil migration was also suppressed by amlodipine and nicardipine, but not by azelnidipine, when these blockers were assessed for their effect on neutrophil migration. CONCLUSIONS These findings suggest that (i) some calcium channel blockers can suppress cytokine-induced neutrophil activation, leading to possible prevention of the progression of atherosclerosis; and (ii) that activation of the ERK and phosphatidylinositol 3-kinase (PI3K)/Akt pathways, induced by TNF-alpha but not by GM-CSF, is selectively affected by some blockers.

Abstract
Angiotensin II (Ang II), a potent vasoconstrictor, has been implicated in vascular inflammation through induction of reactive oxygen species (ROS) and pro-inflammatory genes. Among the chemokines, monocyte chemoattractant protein (MCP)-1 induced by Ang II acts as a central mediator of the inflammatory responses. In the present study, we found that the water extract of ZoaGumHwan (ZGH), a Korean herbal remedy, dose-dependently inhibited Ang II-induced U937 monocyte adhesion to human umbilical vein endothelial cells (HUVECs) and mRNA expression of MCP-1 in HUVECs and C-C chemokine receptor 2 (CCR-2) in U937 cells. In addition, ZGH water extract inhibited Ang II-induced generation of reactive oxygen species in HUVECs in a dose-dependent manner. Berberine, a major component of Coptis chinensis Franch, also showed similar effects on ROS production and MCP-1 expression induced by Ang II. These results suggest that Korean herbal remedy, ZGH, effectively protects against Ang II-induced endothelial inflammation.

Abstract
BACKGROUND Previous study has demonstrated an arterial inflammatory response in aortic tissues in several hypertensive models which can not be fully explained by hemodynamic forces. This study sought to investigate the effect of angiotensin II (Ang II)and its subtype-1 receptor blocker Losartan on the chemokine expression of monocyte chemoattractant protein-1(MCP-1) in aortic tissues of acute stage of 2-kidney-1-clip (2K1C) hypertensive rats. METHODS 2K1C renovascular hypertension was produced in male Wistar-Kyoto(WKY) rats by placing a silver clip with an internal diameter of 0.2 mm around the left renal artery. The MCP-1 mRNA on aortic wall was detected by in situ hybridization and reverse transcription-polymerase chain reaction(RT-PCR); the levels of Ang II in plasma and aorta were determined by radioimmunoassay. The concentration of MCP-1 in supernatant of cultured endothelial cells (ECV-304) was measured by ELISA. RESULTS No MCP-1 was exhibited in aortic wall of normotensive rats both by RT-PCR and in situ hybridization; it would be expressed on the aortic wall of rats in 7 days after 2K1C hypertensive model was formed, especially in intima. The expression of MCP-1 in aortic wall was increased with the duration of hypertension and correlated with local Ang II activity (r=0.594, P=0.02) other than those in plasma, it was decreased obviously after being treated by Losartan for 28 days (optical density of MCP-1/GAPDH ratio: 0, 0.58+/-0.10, 1.14+/-0.09, 1.52+/-0.20, 0.66+/-0.07, respectively, P<0.01). Ang II had increased the expression of MCP-1 in endothelial cells; the highest levels had been performed at 1x10(-7)mol/l Ang II or after 4 h, respectively; and losartan markedly reduced the expression of MCP-1. CONCLUSIONS The expression of MCP-1 significantly increases in aortic tissues of the acute stage 2K1C hypertensive rats and is decreased markedly by treatment of losartan. These findings imply Ang II may be involved in facilitating MCP-1 production in hypertension, and may provide a molecular link between hypertension and the development of atherosclerosis.

Abstract
Electronegative low-density lipoprotein (LDL(-)) is a modified subfraction of LDL present in plasma able to induce the release of interleukin 8 (IL-8) and monocyte chemotactic protein 1 (MCP-1) by human umbilical vein endothelial cells (HUVEC). To ascertain whether further inflammation mediator release could be induced by LDL(-), a protein array system was used to measure 42 cytokines and related compounds. Native LDL and LDL(-) isolated from normolipemic subjects were incubated for 24 h with HUVEC and culture supernatants were used to measure inflammation mediator release. The protein array revealed that IL-6, granulocyte/monocyte colony-stimulating factor (GM-CSF) and growth-related oncogene (GRO) release were increased by cultured HUVEC in response to LDL(-). LDL(-) enhanced production of IL-6 (4-fold vs. LDL(+)), GM-CSF (4-fold), GRObeta (2-fold) and GROgamma (7-fold) was confirmed by ELISA. Time-course experiments revealed that IL-6 was released earlier than the other inflammation mediators, suggesting a first-wave cytokine action. However, the addition of IL-6 alone did not stimulate the production of IL-8, MCP-1 or GM-CSF. Moreover, IL-8, MCP-1 or GM-CSF alone did not promote the release of the other inflammatory molecules. Modification of LDL(+) by phospholipase A(2)-mediated lipolysis or by loading with non-esterified fatty acids (NEFA) reproduced the action of LDL(-), thereby suggesting the involvement of NEFA and/or lysophosphatidylcholine in the release of these molecules. Our results indicate that LDL(-) promotes a proinflammatory phenotype in endothelial cells through the production of cytokines, chemokines and growth factors.

Abstract
BACKGROUND Monocyte chemoattractant protein-1 (MCP-1) plays a crucial role in atherosclerosis and it has been recently proposed as a surrogate biomarker of long-term clinical outcomes in patients with acute myocardial infarction. Little is known of the factors that may influence plasma MCP-1 concentrations. METHODS We studied 384 healthy volunteers and 226 HIV-infected patients as a model of chronic inflammatory condition that predisposes to sub-clinical atherosclerosis. RESULTS In healthy participants there were significant associations between plasma MCP-1 concentration and age, smoking status, and serum triglyceride concentrations that were not observed in the HIV-infected patients. The plasma concentration of MCP-1 was significantly associated with the polymorphism at position -2518 of the MCP-1 gene and, in patients, with the carotid artery intima-media thickness. There were also significant correlations indicating a close association between MCP-1 and HIV disease activity. However, in a multiple regression model, only age, the MCP-1 genotype and smoking status showed significant, and independent, associations with plasma MCP-1 concentrations. CONCLUSION Plasma MCP-1 concentration is genetically determined and associated with age and smoking habit and it also correlates with subclinical atherosclerosis in HIV-infected patients.

Abstract
Chemokine-driven migration of inflammatory cells has been
implicated in pathogenesis of atherosclerosis-associated
conditions such as ischemic stroke and myocardial infarction. In
this study, a candidate chemokine, monocyte chemoattractant
protein (MCP)-1, was investigated in patients with both
aforementioned manifestations of atheroslerotic inflammation.
MCP-1 levels in serum were determined by ELISA in 40 healthy,
control subjects (C), 40 patients with ischemic stroke (IS), and
in 64 patients with myocardial infarction (MI). Statistical
analysis utilised Mann-Whitney test, Fisher's exact test, and
Spearman's rank correlation (P < .05). In comparison to control
subjects (C; median/interquartile range: 239/126 pg/mL), MCP-1
serum levels were increased in both investigated patient cohorts
(IS: 384/370, P < .001; MI: 360/200, P < .002). There was a
substantial variability of MCP-1 serum levels, especially in the
IS group. No relationship was observed between chemokine levels
and atherosclerosis risk factors (hypertension, diabetes, smoking,
and alcohol consumption), and MCP-1 was also not related to age or
gender. Elevation of MCP-1 in circulation of patients with
atherosclerosis-associated complications implicates this CC
chemokine ligand (CCL)2 in inflammatory processes, which
contribute to pathogenesis of myocardial infarction and ischemic
stroke. Further investigations, including patient stratification,
are however necessary to evaluate if MCP-1 can be utilised for
clinical management of patients with these diseases.

Abstract
In type 2 diabetes mellitus, there is increased risk of nephropathy and cardiovascular complications and the incidence of renal failure increases in advanced stages of the disease. Nifedipine, a dihydropyridine-type calcium antagonist, improves endothelial function in hypercholesterolemia by enhancing nitric oxide function, and increases endothelial nitric oxide bioavailability by antioxidative mechanisms. We administered nifedipine, 50 mg/day, to the hypertensive patients for 12 months. There were no other changes in any of the patient's pharmacologic regimen during nifedipine treatment. Clinical and biochemical data obtained before and after nifedipine administration were compared. All markers were measured by ELISA. The levels of platelet activation markers (CD62P, CD63, PAC-1, and Annexin V), microparticles (PDMP and MDMP), RANTES and soluble adhesion markers (sP-selectin and sVCAM-1) differed in the control group and the hypertension group. The levels of these markers were also different in hypertensive patients with and without type 2 diabetes but were unchanged in patients without diabetes in comparison to the control group. However, the concentrations of MDMPs, chemokines, and soluble adhesion markers in hypertensive patients without type 2 diabetes decreased significantly following nifedipine treatment, although the level of RANTES was unchanged. Systolic blood pressure correlated with CD62P, CD63, annexin V, and RANTES levels, and diastolic blood pressure with CD62P and annexin V levels. The effect of nifedipine on platelet activation markers and C-C chemokines in the present study indicates potential effectiveness of calcium antagonist therapy for hypertensive patients with type 2 diabetes.

Abstract
We investigated the effects of long-term benidipine treatment on levels of monocyte and endothelial cell activation markers in hypertensive patients with (n = 28) and without (n = 10) type 2 diabetes mellitus. Benidipine, 4 mg/day, was administered for 6 months; there were no other changes in any of the patients pharmacologic regimens during benidipine treatment. Clinical and biochemical data obtained before and after benidipine administration were compared; all markers were measured by ELISA. The levels of platelet activation markers (CD62P, CD63, and PAC-1), microparticles (monocyte-derived microparticles: MDMPs, and endothelial cell-derived microparticles: EDMPs), chemokines (monocyte chemotactic peptide 1: MCP-1, regulated on activation normally T-cell expressed and secreted: RANTES) and soluble adhesion markers (soluble E-selectin and soluble ICAM-1) differed in the control and hypertension groups. In addition, levels of platelet, monocyte, and endothelial cell activation markers, microparticles, chemokines, and soluble adhesion molecules were higher in hypertensive patients than in those without type 2 diabetes. Furthermore, benidipine administration decreased the concentrations of all these markers. The effect of this drug was significant in diabetes patients with high levels of antioxidized low-density lipoprotein (LDL) antibody. These results suggest that benidipine is effective for the treatment of oxLDL-dependent vascular disorders in hypertensive patients with type 2 diabetes.

Abstract
BACKGROUND The monocyte chemoattractant protein-1 (MCP-1) is a chemokine responsible for the recruitment of monocytes to sites of inflammation. MCP-1 may play critical roles in plaque instability. Anti-inflammation may be one benefit of statin drugs in acute coronary syndrome (ACS). We investigated the effects of atorvastatin therapy on plasma MCP-1 concentrations and production of MCP-1 released by peripheral blood monocytes from ACS patients. METHODS Forty patients with ACS were randomly separated into two groups, those receiving conventional therapy (Group A, n=20), and conventional therapy+atorvastatin (10 mg/day, Group B, n=20). The study the effects of atorvastatin on secretion and expression of MCP-1, human peripheral blood monocytes from healthy donors were incubated with atorvastatin (0.1-10 micromol/l) for up to 24 h in vitro. MCP-1 concentrations in plasma and monocytes culture supernatants were measured by enzyme-linked immunosorbent assays (ELISA). MCP-1 expression was measured by RT-PCR. RESULTS Plasma concentrations of MCP-1 were significantly lower after 4 weeks therapy in both groups of patients [Group A from 97.4 (50.1-164) to 72.6 (36.3-156) pg/ml, Group B from 101 (60-178) to 45 (29-91) pg/ml, (P<0.05, respectively)]. Compared with conventional therapy alone, atorvastatin significantly further reduced plasma MCP-1 concentrations. There was no significant correlation between the degree of changes in plasma MCP-1 and LDL-C. In vitro, atorvastatin inhibits production of MCP-1 up to 73%, in a concentration-dependent manner, and suppressed MCP-1 expression in peripheral blood monocytes. CONCLUSIONS Atorvastatin reduced plasma MCP-1 concentrations in patients with ACS. These effects may explain some clinical benefits of statins in the treatment of these patients.

Abstract
OBJECTIVE Leptin and tumor necrosis factor (TNF)-alpha are associated with insulin resistance and cardiovascular disease. In vitro studies suggested that these effects may be mediated via overproduction of monocyte chemoattracting protein (MCP)-1/CCL2, which is a chemokine involved in the pathogenesis of atherosclerosis. RESEARCH DESIGN AND METHODS In this study, fasting plasma leptin, soluble TNF-alpha receptor 2 (TNF-alpha-R2), and MCP-1/CCL2 concentrations were measured in 207 middle-aged women (age 61 +/- 12 years, BMI 30.1 +/- 6.6 kg/m(2)), including 53 patients with type 2 diabetes, 42 with impaired glucose tolerance, and 112 with normal glucose tolerance, to assess cross-sectionally their relationship with markers of atherosclerosis and, longitudinally over 7 years, whether their circulating levels were associated with cardiovascular disease (CVD) mortality. RESULTS At baseline, leptin and TNF-alpha-R2 were not different among groups; meanwhile, MCP-1/CCL2 was increased in type 2 diabetes (P < 0.05). All showed significant associations with biochemical risk markers of atherosclerosis. In a univariate analysis, age, fasting insulin, leptin, and MCP-1/CCL2 were associated with CVD mortality at 7 years. When a multivariate analysis was performed, only age, leptin, and insulin retained an independent association with CVD mortality, with leptin showing a protective effect (hazard ratio 0.88; P < 0.02). CONCLUSIONS In middle-aged women, MCP-1/CCL2, leptin, and TNF-alpha-R2 were all related to biochemical risk markers of atherosclerosis. MCP-1/CCL2 concentration was the only one to be increased in type 2 diabetes with respect to nondiabetic women and the only one to be associated with increased risk of CVD mortality after a 7-year follow-up period in the univariate analysis. In the multivariate analysis, neither MCP-1/CCL2 nor TNF-alpha-R2 was associated with CVD mortality, and inspection of the data showed that leptin, in both the univariate and multivariate analysis, was associated with a protective effect.

Abstract
BACKGROUND Monocyte chemoattractant protein-1 (MCP-1) is a chemokine responsible for the recruitment of monocytes to sites of inflammation. MCP-1 appears to play a critical role at multiple stages in atherosclerosis, including the initiation of the fatty streak, promotion of plaque instability, and remodeling after myocardial infarction. METHODS AND RESULTS MCP-1 was measured from frozen plasma specimens in 279 healthy volunteers and 2270 patients with acute coronary syndromes enrolled in the Oral Glycoprotein IIb/IIIa Inhibition with Orbofiban in Patients with Unstable Coronary Syndromes (OPUS-TIMI) 16 trial. Median [25th, 75th percentiles] MCP-1 levels were 157 [124, 196] pg/mL in healthy volunteers and 178 [128, 238] pg/mL in the OPUS-TIMI 16 population (P<0.001). In OPUS-TIMI 16, baseline MCP-1 levels were associated with older age, female sex, hypertension, diabetes, prior coronary disease, and renal insufficiency (P<0.01 for each) but not with smoking status, body mass index, ejection fraction, troponin I or C-reactive protein. After adjustment for differences in baseline characteristics, ECG changes, troponin I, and C-reactive protein, an MCP-1 level >75th percentile (corresponding to the 90th percentile in the healthy volunteers) was associated with an increased risk of death or myocardial infarction through 10 months of follow-up (adjusted hazard ratio, 1.53; 95% CI, 1.09 to 2.14; P=0.01). CONCLUSIONS In a large cohort of patients with acute coronary syndromes, an elevated baseline level of MCP-1 was associated both with traditional risk factors for atherosclerosis as well as an increased risk for death or myocardial infarction, independent of baseline variables. Because it appears to play a crucial role at multiple stages of atherosclerosis, MCP-1 is attractive as a surrogate biomarker and merits further study as a potential therapeutic target.

Abstract
Recent investigations have shown that, in addition to neurohormonal system overactivation, another class of biologically active molecules, termed cytokines, is also overexpressed in the setting of chronic heart failure and participates actively in the progression of the syndrome. In this article, we present recent experimental and clinical data describing the pathophysiological role of cytokines in left ventricular remodeling, endothelial dysfunction, and peripheral myopathy characterizing the progression of chronic heart failure, as well as novel therapeutic approaches aimed at attenuating the deleterious effects of cytokines on the cardiovascular system.

Abstract
BACKGROUND This study investigates the plasma activity of inflammatory mediators such as granulocyte-macrophage colony-stimulating factor (GM-CSF), C-C chemokines and soluble adhesion molecules, produced by monocyte-endothelial cell adhesive interaction, in patients with arterial hypertension. METHODS We studied 66 untreated patients with mild to moderate arterial hypertension (hypercholesterolemic: 34, normocholesterolemic: 32) and 30 sex- and age-matched normocholesterolemic normotensive controls. Plasma concentrations of GM-CSF, macrophage chemoattractant protein-1 (MCP-1), macrophage inflammatory protein-1alpha (MIP-1alpha), RANTES (regulated on activation normally T-cell expressed and secreted), soluble intercellular adhesion molecule-1 (sICAM-1) and soluble vascular cell adhesion molecule-1 (sVCAM-1), as well as plasma endothelin-1 (ET-1), were determined in study population by ELISA and RIA, respectively. RESULTS Hypertensives exhibited significantly higher levels of GM-CSF (6.5+/-1.3 vs. 2.3+/-0.7 pg/ml, P=0.099), MCP-1 (175+/-31 vs. 120+/-24 pg/ml, P=0.0093), MIP-1alpha (23+/-4 vs. 15+/-2 pg/ml, P=0.0089), RANTES (17+/-4 vs. 14+/-3 ng/ml, P=0.047), sICAM-1 (235+/-39 vs. 187+/-21 ng/ml, P=0.0041), sVCAM-1 (684+/-42 vs. 589+/-23 ng/ml, P=0.0045) and ET-1 (6.1+/-1.5 vs. 2.4+/-0.3 pg/ml, P=0.0095) than those of normotensives. The normocholesterolemic hypertensives had significantly lower levels of GM-CSF, MCP-1, MIP-1alpha, sICAM-1 and sVCAM-1 than hypercholesterolemic hypertensives but higher than normotensives. In hypertensives, ET-1 levels were significantly correlated with mean arterial pressure (r=0.51, P=0.028), MCP-1 values (r=0.45, P=0.047) and sICAM-1 levels (r=0.64, P=0.0090). Significant correlations were also found between LDL cholesterol values and plasma inflammatory factors GM-CSF (r=0.58, P=0.0088), MCP-1 (r=0.49, P=0.040) and sICAM-1 (r=0.53, P=0.034) in the hypercholesterolemic sub-group of hypertensives. CONCLUSIONS Inflammatory markers of monocyte-endothelial cell adhesive interaction are elevated in hypertensives in comparison to normotensives and may be related to plasma ET-1 activity. The coexistence of hypercholesterolemia may enhance this inflammatory process induced by arterial hypertension.

Abstract
C-C chemokines are essential factors in the recruitment and activation of leukocytes from the circulation into inflamed tissue and may play a role in ischemia-induced myocardial injury and left ventricular remodeling after acute myocardial infarction (AMI). We investigated the kinetics of three major C-C chemokines, macrophage chemoattractant protein-1 (MCP-1), macrophage inflammatory protein-1 alpha (MIP-1 alpha), and regulated on activation normally T cell expressed and secreted (RANTES), in the sera of AMI patients and correlated the findings with the severity of the disease. Serum levels of C-C chemokines were determined in 35 AMI patients by ELISA assays serially during the first week of hospitalization and 1 month after hospital admission. Patients (n = 18) with uncomplicated AMI (Killip class I) were classified as group A, patients (n = 17) with AMI complicated by heart failure manifestations (Killip classes II and III) were classified as group B, and 15 age-matched and sex-matched volunteers were used as healthy controls. A sustained increase in serum C-C chemokines was observed in both AMI groups during the 7-day hospitalization period. Peaks of these inflammatory factors were significantly higher in group B than in group A (MCP-1, 295 +/- 11 vs. 203 +/- 9 pg/ml, p < 0.01; MIP-1 alpha, 30 +/- 1 vs. 24 +/- 2 pg/ml, p < 0.05; RANTES, 32 +/- 2 vs. 16 +/- 1 ng/ml, p < 0.01) and healthy controls (MCP-1, 125 +/- 7 pg/ml, p < 0.001; MIP-1 alpha, 14 +/- 1 pg/ml, p < 0.001; RANTES, 12 +/- 1 ng/ml, p < 0.001). In group B, significant correlations were found between the peak of MCP-1 and the peak of C-reactive protein levels (r = 0.55, p < 0.02) as well as wedge pressure (r = 0.40, p < 0.05). In the same group, the peak of MIP-1 alpha levels was also significantly correlated with the peak of serum creatine kinase-myocardial band (MB) (r = 0.51, p < 0.04) and left ventricular ejection fraction (LVEF) (r = -0.45, p < 0.05). After 1 month, AMI patients (n = 14) with severe left ventricular dysfunction (LVEF < or = 35%) exhibited significantly higher levels of C-C chemokines (all p < 0.05) than the other AMI patients (n = 21) (LVEF > 35%). A significant correlation was found between MIP-1 alpha levels and left ventricular end-diastolic diameter (r = 0.47, p < 0.03) in this patient population. In conclusion, we have detected a significant elevation of major C-C chemokines during the course of AMI, with the highest levels in patients with AMI complicated by heart failure manifestations and severe left ventricular dysfunction. The elevation of these chemotactic inflammatory factors may actively contribute to the pathophysiology of the disease and the subsequent left ventricular remodeling.
