Abstract
AIMS In a randomized, parallel, blinded study, we investigate the impact of clopidogrel, prasugrel, or ticagrelor on peripheral endothelial function in patients undergoing stenting for an acute coronary syndrome. METHODS AND RESULTS The primary endpoint of the study was the change in endothelium-dependent flow-mediated dilation (FMD) following stenting. A total of 90 patients (age 62 ± 9 years, 81 males, 22 diabetics, 49 non-ST elevation myocardial infarctions) were enrolled. There were no significant differences among groups in any clinical parameter. Acutely before stenting, all three drugs improved FMD without differences between groups (P = 0.73). Stenting blunted FMD in the clopidogrel and ticagrelor group (both P < 0.01), but not in the prasugrel group. During follow-up, prasugrel was superior to clopidogrel [mean difference 2.13, 95% confidence interval (CI) 0.68-3.58; P = 0.0047] and ticagrelor (mean difference 1.57, 95% CI 0.31-2.83; P = 0.0155), but this difference was limited to patients who received the study therapy 2 h before stenting. Ticagrelor was not significantly superior to clopidogrel (mean difference 0.55, 95% CI -0.73 to 1.82; P = 0.39). No significant differences were seen among groups for low-flow-mediated dilation. Plasma interleukin (IL)-6 (P = 0.02 and P = 0.01, respectively) and platelet aggregation reactivity in response to adenosine diphosphate (P = 0.002 and P = 0.035) were lower in the prasugrel compared to clopidogrel and ticagrelor group. CONCLUSION As compared to ticagrelor and clopidogrel, therapy with prasugrel in patients undergoing stenting for an acute coronary syndrome is associated with improved endothelial function, stronger platelet inhibition, and reduced IL-6 levels, all of which may have prognostic implications. This effect was lost in patients who received the study medication immediately after stenting. EUDRACT-NO 2011-005305-73.

Abstract
We identified the prevalence of elevated high-sensitivity C-reactive protein and interleukin-6 in patients with recent cardiovascular (CV) events with or without prediabetes/diabetes, and in a control group of patients with remote CV events. Interleukin-6 was elevated in patients with prediabetes/diabetes and recent CV events (median, 4.84 pg/mL; interquartile range, 3.27-7.45) compared with patients with remote events (2.36 pg/mL; interquartile range, 1.09-4.00). There was a trend for elevated high-sensitivity C-reactive protein in patients with acute events and prediabetes/diabetes (P = 0.147). This supports the notion that patients with prediabetes/diabetes and recent CV events have higher inflammatory burdens than patients without recent CV events or dysglycemia.

Abstract
AIMS The aim of this study was to report on the midterm outcomes of patients undergoing percutaneous coronary intervention with bioresorbable vascular scaffolds (BVS) for the treatment of acute coronary syndromes (ACS) and compare with those of patients with stable coronary artery disease (sCAD). METHODS AND RESULTS One thousand four hundred and seventy-seven (1,477) patients underwent implantation of one or more BVS (Absorb BVS; Abbott Vascular, Santa Clara, CA, USA) at 11 European centres and were included in the GHOST-EU registry. Admissions comprised 47.1% of the patients (951 BVS) with ACS, and 52.8% (1,274 BVS) with sCAD. During a median follow-up of 384 (359-460) days, patient-oriented endpoints (PoCE), including all-cause death, any infarction, any revascularisation, were recorded in 271 patients (12-month incidence in ACS patients: 18.5% vs. 11.6% in the sCAD group, p<0.001). Device-oriented composite endpoints (DoCE), cardiac death, target vessel infarction and target lesion revascularisation, were observed in 98 patients (12-month incidence of 4.2% in the sCAD group, 6.4% in the ACS group; p=0.052). The 12-month incidence of definite scaffold thrombosis was 2.6% in ACS patients and 0.8% in XIENCE patients (p=0.006). In multivariate analysis, ACS was a predictor of DoCE (HR: 2.26 [1.34-3.81], p=0.002), PoCE (HR: 1.71 [1.13-2.58], p=0.011), and stent thrombosis (HR: 2.51 [1.13-5.60], p=0.025). In contrast, the incidence of target lesion revascularisation was not different between groups. There was no difference in the incidence of any of these endpoints among the different clinical presentations (unstable angina, non-ST-elevation infarction and ST-elevation infarction). CONCLUSIONS PoCE, DoCE and scaffold thromboses were more frequent in ACS patients, without any difference among different forms of ACS.

Abstract
Peripheral arterial disease (PAD) is a manifestation of systemic atherosclerosis, recognized as an inflammatory disease of the vessel wall, probably accelerated by diabetes mellitus (DM). Elevated interleukin (IL)-6 levels have been associated with increased cardiovascular morbidity and a common polymorphism has been identified in the promoter region of the IL-6 gene. The aim of this prospective study was to investigate inflammatory mediators in PAD patients (±DM) and to investigate a possible relationship to the IL-6 gene polymorphism. Five groups of patients (DM, intermittent claudication ±DM, critical limb ischemia (CLI) ±DM) and a control group of 20 individuals each were included. Hemoglobin, high sensitive C-reactive protein (hsCRP), creatinine, blood lipids, white blood cells (WBC); CD11b/CD18; vascular cell adhesion molecule (sVCAM-1), intercellular adhesion molecule (sICAM-1), sE-selectin, sP-selectin; IL-6, IL-8, tumour necrosis factor (TNF)α, sTNFα-R1 and sTNFα-R2 were analysed. The IL-6 gene polymorphism was determined in all groups and also compared with 200 healthy controls from a larger study of blood donors. In a multiple regression analysis, adjusted for gender, smoking and age, the effect of CLI was significantly ( p < 0.05) associated with elevated levels of the WBC count, hsCRP, proinflammatory cytokines (IL-6, TNFα-R1-2) and endothelial (sICAM, sVCAM) and WBC (CD11b gran) markers. The effect of less advanced PAD (intermittent claudication) was related to an increased concentration of sVCAM-1 and the number of monocytes and granulocytes. DM or leg ulcers were not significantly related to any of the markers. No significant difference in frequency of the various IL-6 genotypes was found between the groups or when compared with the group of 200 blood donors ( p > 0.3). Activation of cytokines, endothelial cells and WBC was related to the Fontaine stage of PAD but not to the presence of DM or ulcers. No association was found between the polymorphism in the IL-6 promoter region and PAD.

Abstract
INTRODUCTION Particularly in the setting of acute coronary syndromes, the interplay between vascular and platelet function has been postulated to have direct clinical implications. The present trial is designed to test the effect of clopidogrel, prasugrel and ticagrelor on multiple parameters of vascular function, platelet aggregation, oxidative and inflammatory stress before and up to 4 weeks after coronary artery stenting. METHODS AND ANALYSIS The study is designed as a three-arm, parallel design, randomised, investigator-blinded study. Patients with unstable angina or non-ST elevation myocardial infarction undergoing coronary intervention with a drug-eluting stent will be randomised to receive 600 mg clopidogrel, 60 mg prasugrel or 180 mg ticagrelor followed by oral therapy with the same drug. The primary endpoint of the trial is the impact of antiplatelet treatments on endothelial function as assessed by flow-mediated dilation at 1 day, 1 week and 1 month in patients who have undergone stenting. Secondary endpoints include the impact of study medications on parameters of macrovascular and microvascular function, platelet reactivity, oxidative and inflammatory stress. The study recruitment is currently ongoing and, after an interim analysis which was performed at 50% of the initially planned population, it is planned to continue until July 2015. ETHICS AND DISSEMINATION The protocol was approved by the local ethics committee. The trial will provide important pathophysiological insight on the relationship between platelet aggregation and endothelial function, two parameters that have been shown to influence patients' prognosis.

Abstract
OBJECTIVE It is unknown whether the effect of diabetes on patients with unprotected left main coronary artery (LMCA) disease differs according to the different revascularization strategies. This study was conducted to evaluate the impact of diabetes on patients with unprotected LMCA disease treated with either percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG). PATIENTS AND METHODS We prospectively enrolled 823 consecutive patients with unprotected LMCA disease who had drug-eluting stent (DES; n = 331) implantation or underwent CABG (n = 492) in the study. We compared the effects of diabetes on clinical outcomes according to different revascularization strategies. RESULTS Among 823 eligible patients enrolled, 226 had diabetes. In the DES population, no significant differences were observed in occurrences of death, cardiac death, repeat revascularization, stroke, and major adverse cardiac and cerebrovascular events. However, the risks of the composite of death/myocardial infarction (MI)/stroke (21.5 % DM vs. 7.2 % non-DM; p = 0.001) and MI (15.4 % DM vs. 1.6 % non-DM; p = 0.000) were significantly higher in the diabetic patients than those without diabetes. In the CABG population, similar rates of all clinical endpoints were observed between the diabetic and nondiabetic group. CONCLUSION Diabetes was associated with worse outcome in patients undergoing DES implantation for the treatment of unprotected LMCA disease. However, its negative prognostic impact was not found among patients undergoing CABG.

Abstract
OBJECTIVE To study leukocyte activation after percutaneous coronary intervention in patients with previous ST elevation myocardial infarction. METHODS Neutrophil and monocyte activation (by flow cytometric assessment of the surface expression of CD11b and CD62L adhesion molecules) was assessed in 39 patients during the subacute period of a previous ST elevation myocardial infarction initially treated with fibrinolytic agents, before and after diagnostic coronary angiography (coronary angiography control phase) as well as before and after stent implantation (percutaneous coronary intervention phase). Simultaneous evaluation of C-reactive protein (C-reactive protein immonoturbidimetry) and plasma cytokine levels (interleukins-1, -6, -10 and tumor necrosis alpha by immunoassay) was also performed. To track the earliest detectable change in the first few minutes after stent deployment, all measurements were performed before and 60 min after the procedures. RESULTS CD11b expression increased 1 h after stent deployment in neutrophils (P<0.0001) and monocytes (P<0.0001). A comparable increase, however, was also observed after coronary angiography (neutrophils, P=0.03; monocytes, P=0.01), although the increase of CD11b expression was greater after percutaneous coronary intervention on both neutrophils (90 vs. 40%, P=0.014) and monocytes (65 vs. 33%, P=0.04). CD62L expression decreased significantly after percutaneous coronary intervention (neutrophils, P=0.01; monocytes, P=0.006), but remained unchanged after coronary angiography. Plasma cytokine and C-reactive protein concentrations did not change after the procedures. CONCLUSION CD62L appears to be a specific and reliable early cellular biomarker of leukocyte activation after percutaneous coronary intervention, when this procedure is performed in patients with previous ST elevation myocardial infarction. Whether this marker represents also a potential predictor of future events and/or restenosis in this group of patients remains to be defined.

Abstract
Peripheral arterial disease (PAD) is a growing health problem for many Americans and often occurs along with other cardiovascular risk factors, including diabetes mellitus (DM), low-grade inflammation, hypertension, and lipid disorders. Intermittent claudication (IC), an early manifestation of PAD, commonly leads to reduced quality of life for patients who are limited in their ambulation. While recent wide adoption of percutaneous peripheral interventional (PPI) techniques has increased the number patients being aggressively treated for IC, the overall effectiveness of PPI for the treatment of IC is not well known, especially for DM patients who have both hemodynamic and functional obstacles to treatment success. This review is designed to illustrate how treatment outcomes for IC can be measured by different modalities and how diabetes and inflammation can influence those outcomes. In the setting of greater concern for health care resources and clinical accountability, better understanding of treatment outcomes and efficacy will help us manage these complex challenges.

Abstract
AIM To investigate release of some inflammatory cytokines (Cys) after coronary angioplasty and its links with coronary atherosclerosis. METHODS Twenty-seven consecutive subjects with acute coronary syndrome (ACS) who underwent percutaneous coronary intervention (PCI) were enrolled in the study: serial blood samples were taken in order to evaluate plasma concentrations of Interleukin (IL)-2, IL-10, IL-18, TNFalpha, and IFNgamma just before PCI at 12 and 24 hours. Patients were then divided, considering balance between each inflammatory Cy and IL-10, an antiinflammatory Cy, into four groups, ranging from a prevalent antiinflammatory response (stable inflammatory Cy-increasing IL-10 values) to a marked inflammatory imbalance (increasing inflammatory Cy-stable IL-10 values). RESULTS All Cys showed significant increases in plasma concentrations if compared with baseline values. Release curves were not significantly different when comparing subjects with ST-elevation myocardial infarction (STEMI) versus unstable angina-non-STEMI (UA-NSTEMI), diabetics versus controls. Subjects with marked inflammatory response showed a higher incidence of stenosis on left anterior descending (LAD) coronary artery (IL-2 chi(2) and IFNgamma P < 0.05); Cy release was higher in patients with multivessel coronary disease (IL-2 and IFNgamma, ANOVA P < 0.01). Correlations were also referable between Cys and myocardial enzyme release. Subjects treated with sirolimus-eluting stents (SES) showed significantly lower Cy periprocedure ratio if compared with those treated with bare metal stents. CONCLUSIONS A significant Cy release is detectable after PCI: inflammatory response seems to correlate with both PCI due to plaque instabilization and coronary atherosclerosis. A blunted inflammatory response is detectable in subjects treated with SES.

Abstract
UNLABELLED Coronary artery calcification may play a significant role in the pathophysiology of plaque progression and healing. We hypothesized that osteoprotegerin, an inhibitor of osteoclastogenesis, may participate in the calcification of coronary plaques or the response to injury after coronary stenting. A prospective registry was performed in 2004. Blood samples from 100 patients undergoing percutaneous coronary intervention (PCI) were obtained before PCI and 24 h after PCI. The concentrations of osteoprotegerin (OPG), C-reactive protein, interleukin-6, and soluble CD40 ligand (sCD40L) were determined by ELISA. Quantitative coronary angiography was performed to define the presence of culprit lesion calcification (CLC). Comparisons among markers of inflammation and tertiles of OPG were stratified with respect to CLC. Patients with CLC (n = 28) compared with no CLC (n = 71) were older (P < 0.01), had lower creatinine clearance (P < 0.01), lower hemoglobin (P = 0.02), and were less likely to smoke (P = 0.04). Patients without CLC were over twice as likely to present with a marker-positive acute coronary syndrome. CLC was associated with less pre-PCI platelet-mediated inflammation as measured by sCD40L (4.65 vs. 7.15 pg/ml, P = 0.05), but not with lower levels of OPG. Inflammatory cytokines increased significantly after PCI for patients with and without CLC. For patients in the highest tertile of OPG at baseline, there was a reduction in OPG after PCI. Systemic osteoprotegerin levels are not associated with angiographic calcification of culprit plaques. For patients with elevated levels of OPG prior to PCI, there is a significant reduction after PCI consistent with a counterregulatory role for OPG. CONDENSED ABSTRACT Both calcified and non-calcified culprit plaques exhibited a similar inflammatory response to stent-mediated injury. After PCI, osteoprotegerin decreased while proinflammatory cytokines increased, which may be consistent with a counterregulatory role for osteoprotegerin.

Abstract
BACKGROUND Systemic inflammation after coronary intervention identifies patients at increased risk of subsequent cardiac events. Cardiac events are less frequent after use of drug eluting stents (DES) compared with bare metal stents (BMS). Thus, we sought to determine whether attenuation of the systemic inflammatory response was contributing to the improved outcomes. METHODS A prospective registry was initiated in late 2003. Peripheral venous blood samples from 75 patients undergoing percutaneous coronary intervention (PCI) were obtained before PCI, and both 1 hour and 24 hours after stenting. The concentrations of C-reactive protein (CRP), interleukin-6 (IL-6) and interleukin-1 receptor antagonist (IL1-Ra) were determined by ELISA. Eleven patients were excluded from the analysis because they had both DES and BMS. RESULTS Patients treated with BMS (n=29) compared with DES (n=34) had a higher incidence of marker-positive acute coronary syndromes (40% vs. 17%, p=0.06), vein graft PCI (p=0.02) and a larger final balloon diameter (p=0.04). Consistent with the lower baseline clinical risk, pre-PCI concentrations of cytokines were lower in the DES group (p=0.04 for IL-6 and p=0.08 for CRP). Comparable and significant increases in CRP, IL-6 and IL1-Ra were evident 24 hours after PCI in patients treated with either DES or BMS. After controlling for baseline levels of CRP, there remained a similar and robust (300%) relative increase in CRP for both DES and BMS patients. CONCLUSIONS The inflammatory response to PCI appears similar in those treated with DES and BMS. Accordingly, the reduction in restenosis after DES is likely not mediated by attenuation of the systemic markers CRP, IL-1Ra, or IL-6.

Abstract
An elevated white blood cell (WBC) count and elevated C-reactive protein (CRP) have been associated with an increased risk of adverse cardiac events. The relation between these 2 parameters of heightened systemic inflammation was characterized in patients who underwent percutaneous coronary intervention (PCI). Femoral arterial blood samples from a prospective registry of 100 patients who underwent PCI were obtained immediately before the procedure. The concentrations of CRP and interleukin-6 were determined by an enzyme-linked immunosorbent assay. Patients were stratified according to tertiles of ascending WBC counts before PCI. Univariate analysis compared patients in the highest WBC count tertile with the lower tertiles for clinical, angiographic, and procedural characteristics, as well as pre-PCI cytokine concentrations. Multiple logistic regression analysis was performed to examine the association between the elevated WBC count and baseline elevations in either CRP or interleukin-6, accounting for the simultaneous effect of confounding characteristics. Approximately 75% of patients had stable or unstable angina pectoris versus a marker-positive acute coronary syndrome. Patients in the highest WBC count tertile were more likely to be smokers, have received unfractionated heparin, have a marker-positive acute coronary syndrome, and have a CRP >3.0 mg/L. Multivariate analysis showed that only elevated troponin-I before PCI was independently associated with the highest WBC count tertile (odds ratio 10.9, 95% confidence interval 3.7 to 32.4, p < 0.01). In patients with negative troponin I findings, CRP >3.0 mg/L was a powerful independent predictor of an elevated pre-PCI WBC count (odds ratio 3.78, 95% confidence interval 1.07 to 13.3, p = 0.04). In conclusion, in patients with troponin I negative coronary syndromes, a pre-PCI elevation in the WBC count reflected cytokine-mediated inflammation.

Abstract
BACKGROUND The systemic inflammatory response to percutaneous coronary intervention (PCI) is associated with recurrent cardiac events; however, the pathophysiology of this inflammatory response is not well understood. The present study was performed to investigate the role of pathogen burden of infection in determining the magnitude of C-reactive protein (CRP) and interleukin 6 (IL-6) response to PCI. METHODS One hundred patients with stable angina pectoris undergoing elective PCI at a single center were recruited. Antibodies against cytomegalovirus, Chlamydia pneumoniae , Epstein-Barr virus, Helicobacter pylori , and herpes simplex virus types 1 and 2 were determined before PCI. Plasma CRP and IL-6 levels were measured before and 6, 24, 48, 72 hours after PCI and data presented as area under the curve. RESULTS Plasma CRP and IL-6 concentrations increased significantly after PCI. Neither antibodies against single nor multiple pathogens were associated with the CRP or IL-6 response to PCI. No correlations were found between the inflammatory markers and troponin T levels after PCI. With the exception for CRP and body mass index (R = 0.20, P < .05), neither risk factors for coronary heart disease nor medication but stent implantation was associated with increased plasma CRP (76 vs 61 mg/L, P < .005) and IL-6 (74 vs 64 pg/mL, P < .005) levels after PCI. CONCLUSION Stent implantation, but not pathogen burden, is associated with the plasma CRP and IL-6 response to PCI.

Abstract
We evaluated C-reactive protein increases after implantation of bare metal stents in 200 patients and sirolimus-eluting stents in 100 patients. The magnitude of change in C-reactive protein was comparable between groups. Clinical follow-up showed a relation between the postprocedural C-reactive protein increase and outcome that was significant in the bare metal stent group, which accounted for the most of events, but not in the sirolimus-eluting stent group.

Abstract
BACKGROUND This prospective study evaluated the early increase in markers of inflammation after coronary stenting, and the predictors of early rise. Elevation of markers of inflammation after percutaneous coronary intervention correlates with an increased risk of adverse events. The role of soluble CD40 ligand (sCD40L) as a potential initiator of inflammation after stenting has not been described. METHODS Seventy-five patients were treated with heparin alone (n=25), or randomized to adjuvant treatment with eptifibatide (n=26) or abciximab (n=24) during stenting. Systemic blood was obtained before coronary stenting and at 10 min after stenting. C-reactive protein (CRP), interleukin (IL)-6, IL-1 receptor antagonist and sCD40L were determined by enzyme liberated immunosorbent assay. RESULTS sCD40L exhibited the greatest relative rise (35%, P=0.01 compared to concentrations before intervention) in the first 10 min after stenting. In a logistic regression model, an early increase in the concentration of sCD40L was predicted by baseline laboratory values (white blood count and sCD40L level before stenting) and procedural characteristics (number of stents and glycoprotein IIb-IIIa inhibitor assignment). CONCLUSIONS In conclusion, a systemic inflammatory response is detectable 10 min after coronary stent placement. The early increase in sCD40L suggests a possible role for this marker in the initiation of inflammation after coronary stenting.

Abstract
We studied 30 consecutive patients who underwent coronary stenting with respect to postprocedure endothelial dysfunction and levels of pre- and postprocedure cytokines. Patients with severe impairment of flow-mediated dependent dilation, but not flow- mediated independent dilation, had higher concentrations of C-reactive protein before percutaneous coronary intervention (12.9 +/- 20.2 vs 5.6 +/- 13.0 microg/ml, p = 0.04) and 24 hours after stenting (18.8 +/- 20.8 vs 11.8 +/- 20.0 microg/ml, p = 0.05) than patients without severe abnormities of systemic endothelial function. Thus, endothelium-dependent dilation abnormalities were related to the systemic inflammatory state, whereas endothelium-independent dilation abnormalities were not related to the inflammatory status of the patient.

Abstract
INTRODUCTION Atherosclerosis is looked upon as an inflammatory disease. The production of proinflammatory markers may indicate activity in this inflammatory state. METHODS We prospectively evaluated a range of proinflammatory serum parameters in 136 cardiac patients who had previously undergone percutaneous coronary intervention (PCI). RESULTS By means of myocardial scintigraphy, an ischemia group (A; n=49) and a group with stable cardiovascular disease without exercise induced ischemia (B; n=87) were distinguished. Risk factors and lipoprotein profile of both groups were comparable. Serum levels of serum C-reactive protein (CRP), IL-6, sTNF-RI, IGF-I, neopterin, serotonin and prolactin did not present any significant difference between the two groups. CONCLUSIONS We conclude that measurement of these (inflammatory) parameters does not help to delineate post-PCI cardiac patients with and without exercise-induced ischemia.
