Abstract
OBJECTIVE This study aims to assess the predictive value of the Systemic Immune Inflammation Index (SII) in determining in-stent restenosis (ISR) likelihood in patients with acute coronary syndrome (ACS) who have undergone percutaneous coronary intervention (PCI). METHODS The study enrolled 903 ACS patients undergoing PCI, categorized into ISR (+) and ISR (-) groups based on control coronary angiography results. Demographic, clinical, laboratory, and angiographic-procedural characteristics were systematically compared. RESULTS The ISR (+) group encompassed 264 individuals (29.2%), while the ISR (-) group comprised 639 individuals (70.8%). Patients had a mean age of 55.8 ± 10.2 years, with 69% being male. The ISR (+) group had higher diabetes and smoking prevalence and notably larger stent dimensions. Lab parameters showed significantly elevated creatinine, total cholesterol, red cell distribution width, white blood cell and neutrophil counts, SII index and C-reactive protein (CRP) in the ISR (+) group, while lymphocyte levels were lower. Binary logistic regression identified stent diameter (odds ratio [OR]: 0.598, 95% confidence interval [CI]: 0.383-0.935; P = 0.024), stent length (OR: 1.166, 95% CI: 1.132-1.200; P < 0.001), creatinine (OR: 0.366, 95% CI: 0.166-0.771; P = 0.003), CRP (OR: 1.075, 95% CI: 1.042-1.110; P = 0.031), and SII index (OR: 1.014, 95% CI: 1.001-1.023; P < 0.001) as independent ISR predictors. CONCLUSION The SII index exhibits potential as a predictive marker for ISR in ACS patients post-PCI, indicating systemic inflammation and heightened restenosis risk. Integrating the SII index into risk models could identify high-risk patients for targeted interventions.

Abstract
Background:
Inflammation plays a pivotal role in the pathogenesis of In-Stent Restenosis (ISR). High sensitivity C-reactive protein (hsCRP) is positively associated with major cardiovascular events.
Aim:
We aimed to investigate the hsCRP inflammatory response to Percutaneous Coronary Intervention (PCI) in Coronary Artery Disease (CAD) patients with coronary ISR vs. patients without ISR.
Methods:
This case-control study included 80 CAD patients previously treated with drug-eluting stent (DES) implantation. Patients had Coronary Angiography (CAG) because of chest pain or equivalent symptoms and were subdivided into 2 groups. Group A (n=40) included CAD patients with ISR. Group B (n=40) included age and gender-matched controls with CAD but without ISR. Serum hsCRP levels were obtained before PCI (baseline) and 8, 16, 24 h post-PCI.
Results:
At baseline (before intervention/CAG), the hsCRP level was increased in the ISR group compared with the No-ISR group (p=0.007). There were 36 (90%) patients in the ISR group who had a high hsCRP (>3 mg/L) compared with 25 (62.5%) patients in the No-ISR group. Also, there was a significant relationship between high hsCRP and the ISR. Patients with ISR had higher frequencies and percentages of elevated CRP than the no-ISR control group. This difference was maintained for all measurements, baseline, after 8, 16, and 24 h (p<0.05). Repeated measures analysis of variance (ANOVA) in the ISR group revealed that mean hsCRP differed significantly between serial measurements (p<0.001). In contrast, in the control group, the mean hsCRP did not differ significantly between the serial measurements (p=0.65).
Most of our patients (n=66, 82.5%) had 1-vessel CAD disease, and the left anterior descending (LAD) coronary artery was significantly affected in 46 patients (57.5%). Management of restenosis was accomplished mainly by stenting by DES in 29 patients (72.5%).
Conclusion:
Patients with ISR had substantially higher pre- and post-PCI hsCRP levels than the no-ISR controls. This difference was maintained up to 24h post-PCI. Conversely, the mean hsCRP did not significantly differ at the follow-up points for the controls without ISR.

Abstract
BACKGROUND Evidence reveals that inflammatory factors can predict coronary restenosis in patients suffering from coronary heart disease (CHD) after percutaneous coronary intervention (PCI). Perhaps, inflammatory factors are promising biomarkers for the diagnosis of coronary restenosis after PCI. However, the accuracy of inflammatory factors has not been systematically evaluated. Therefore, it is necessary to perform a meta-analysis to certify the diagnostic values of inflammatory factors on coronary restenosis after PCI. METHODS China National Knowledge Infrastructure (CNKI), Wanfang, VIP, China Biology Medicine disc (CBM), PubMed, EMBASE, Cochrane Library and Web of Science were searched for relevant studies to explore the potential diagnostic values of inflammatory factors on coronary restenosis after PCI from inception to January 2021. All data were extracted by 2 experienced researchers independently. The risk of bias about the meta-analysis was confirmed by the Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2). The data extracted were synthesized and heterogeneity was investigated as well. All of the above statistical analyses were carried out with Stata 16.0. RESULTS The results of this meta-analysis will be submitted to a peer-reviewed journal for publication. CONCLUSION This study clarified confusions about the specificity and sensitivity of inflammatory factors on coronary restenosis after PCI, thus further guiding their promotion and application. ETHICS AND DISSEMINATION Ethical approval will not be necessary since this systematic review and meta-analysis will not contain any private information of participants or violate their human rights.

Abstract
Background The incidence of recurrent cardiovascular events from the progression of nontarget lesions (NTLs) is high for percutaneous coronary intervention-treated patients. However, the underlying mechanisms have not been thoroughly elucidated. Methods In this study, ten atherosclerotic rabbits with multiple plaques in the upper and lower segments of abdominal aorta (group A) were randomly divided into two subgroups: group A1 underwent intravascular ultrasound examination and stent implantation in the lower segments of the abdominal aorta (n=5), whereas group A2 was without stenting (n=5). Group B was a control group without balloon injury. The serum levels of high-sensitivity CRP, interleukin-6 (IL-6), oxidized low-density lipoprotein, and CD36 were assessed via ELISA at five time points between the 10th and 18th weeks. The upper abdominal aorta was examined via the immunohistochemical stain and Western blotting of matrix metallopeptidase 9 (MMP-9), CD36, IL-6, and tumor necrosis factor α. Results As a result, we found that stent implantation aggravated serum levels of CD36, oxidative stress, and inflammatory cytokines. Meanwhile, the upper abdominal arterial plaque burden significantly increased after stenting by intravascular ultrasound. Immunohistochemistry and Western blotting showed that the local NTLs’ matrix metallopeptidase 9, CD36, IL-6, and tumor necrosis factor α expressions in group A1 were significantly higher than those in groups A2 and B (P<0.05–0.01). More importantly, a strong correlation was identified between CD36 expression and NTLs’ plaque burden before the rabbits were killed. Conclusion Taken together, stent implantation accelerated inflammation, induced oxidative stress, and increased the NTLs’ progression, which were associated with the upregulated CD36 expression.

Abstract
To derive insights into the temporal changes in oxidative, inflammatory and coagulation biomarkers in patients with stable angina undergoing percutaneous coronary intervention (PCI). PCI is associated with a variety of biochemical and mechanical stresses to the vessel wall. Oxidized phospholipids are present on plasminogen (OxPL-PLG) and potentiate fibrinolysis in vitro. We recently showed that OxPL-PLG increase following acute myocardial infarction, suggesting that they are involved in atherothrombosis. Plasma samples were collected before, immediately after, 6 and 24 h, 3 and 7 days, and 1, 3, and 6 months after PCI in 125 patients with stable angina undergoing uncomplicated PCI. Plasminogen levels, OxPL-PLG, and an array of 16 oxidative, inflammatory and coagulation biomarkers were measured with established assays. OxPL-PLG and plasminogen declined significantly immediately post-PCI, rebounded to baseline, peaked at 3 days and slowly returned to baseline by 6 months (p < 0.0001 by ANOVA). The temporal trends to maximal peak in biomarkers were as follows: immediately post PCI: OxPL-apoB and lipoprotein (a); Day 1-the inflammatory biomarker IL-6; Day 3-CRP and coagulation biomarkers OxPL-PLG, plasminogen and tissue plasminogen activity; Day 3 to 7-plasminogen activator inhibitor activity, and complement factor H binding to malondialdehyde-LDL and MDA-LDL IgG; Day 7-30 MDA-LDL IgM, CuOxLDL IgM, and ApoB-IC IgM and IgG; >30 days uPA activity, uPA antigen, CuOxLDL IgG and peptide mimotope to MDA-LDL. Most of the biomarkers trended to baseline by 6 months. PCI results in a specific, temporal sequence of changes in plasma biomarkers. These observations provide insights into the effects of iatrogenic barotrauma and plaque disruption during PCI and suggest avenues of investigation to explain complications of PCI and development of targeted therapies to enhance procedural success.

Prognostic Impact of 9-Month High-Sensitivity C-Reactive Protein Levels on Long-Term Clinical Outcomes and In-Stent Restenosis in Patients at 9 Months after Drug-Eluting Stent Implantation. PLoS One 2015; 10:e0138512.

Abstract
Introduction The level of 9-month high-sensitivity C-reactive protein (hsCRP) in predicting cardiovascular outcomes is scanty in patients at 9 months after receiving drug-eluting stent (DES) implantations. This study aims to evaluate the relationship between 9-month follow-up hsCRP levels and long-term clinical outcomes in patients at 9 months after receiving DES. Methods A total of 1,763 patients who received 9-month follow-up angiography were enrolled and grouped according to hsCRP level 9 months after the DES implantation: group I (718 patients, hsCRP<1.0 mg/L), group II (639 patients, 1.0≦hsCRP≦3.0 mg/L), and group III (406 patients, hsCRP>3.0 mg/L). Results Group III patients had a lower cardiovascular event-free survival rate than group I or II patients during a follow-up of 64±45 months (64.5% vs. 71.6% vs. 72.8%, respectively, p = 0.012). Multivariate analysis showed that a follow-up hsCRP level <3.0 mg/L was an independent predictor of a major adverse cardiovascular event (cardiac death, reinfarction, target lesion revascularization, stenting in a new lesion, or coronary bypass surgery). Group III patients had a higher restenosis rate (11.3% vs. 5.8% vs. 6.6%, respectively, p = 0.002) and loss index (0.21±0.32 vs. 0.16±0.24 vs. 0.18±0.28, respectively, p = 0.001) than group I or II patients in 9-month follow-up angiography. Conclusions A high 9-month follow-up hsCRP level is an independent predictor of long-term clinical cardiovascular outcomes in patients at 9 months after DES implantation. It is also associated with a higher restenosis rate, larger late loss and loss index at 9 months after DES implantation.

Abstract
Background Lipoprotein associated phospholipase A2 (Lp-PLA2) is a novel biomarker for cardiovascular risk prediction. Whether increased Lp-PLA2 level is associated with re-stenosis after stent-placement is unclear. Methods Totally 326 participants eligible for stent-placement were enrolled and divided into two groups according to baseline Lp-PLA2 levels (named normal and elevated groups). Baseline characteristics and clinical outcomes were compared between normal and elevated groups. The relationships between Lp-PLA2 and other risk factors with re-stenosis were evaluated. Results Only the between-group difference of Lp-PLA2 was significant (123.2 ± 33.6 ng/mL vs 336.8 ± 85.4 ng/mL, P < 0.001) while other demographic and clinical characteristics between these two groups were comparable. Approximately 55.1% and 58.5% of participants in normal and elevated groups presented with acute coronary syndrome, and the percentage of tri-vessels stenoses was significantly higher in elevated group (40.8% vs 32.1%, P = 0.016). Nearly 96.0% and 94.0% of participants in normal and elevated Lp-PLA2 groups were placed with drug-eluting stents, and the others were with bare-metal stents. After 1 year’s follow-up, the incidence of clinical end-points was comparable (13.3% vs 15.4%, P = 0.172). Nevertheless, the incidence of re-stenosis was marginally higher in elevated Lp-PLA2 group (8.5% versus 4.6%, P = 0.047). With multivariate analysis, after adjustment for other risk factors, Lp-PLA2 remained an independent predictor for re-stenosis with a hazard ratio of 1.140. No synergistic effect between Lp-PLA2 and other risk factors for re-stenosis was found. Conclusion Increased Lp-PLA2 level is associated with an increased risk of re-stenosis. Lp-PLA2 assessment may be useful in predicting subjects who are at increased risk for re-stenosis.

Abstract
INTRODUCTION AND OBJECTIVES High baseline levels of interleukin-6 and C-reactive protein confer an increased risk of mortality in non-ST-segment elevation acute coronary syndrome. The aim of the study was to determine whether serial measurements of interleukin-6 and high-sensitivity C-reactive protein provide additional information to baseline measurements for risk stratification of non-ST-segment elevation acute coronary syndrome. METHODS Two hundred and sixteen consecutive patients with non-ST-segment elevation acute coronary syndrome were prospectively included. Blood samples were obtained within 24 h of hospital admission and at 30 days of follow-up. The endpoint was a composite of all-cause death, nonfatal myocardial infarction, or acute decompensated heart failure. RESULTS Both interleukin-6 and high-sensitivity C-reactive protein levels decreased from day 1 to day 30, regardless of adverse events (both P<.001). Interleukin-6 levels at 2 time points (interleukin-6 day 1, per pg/mL; hazard ratio=1.006, 95% confidence interval, 1.002-1.010; P=.002 and interleukin-6 day 30, per pg/mL, hazard ratio=1.047, 95% confidence interval, 1.021-1.075, P<.001) were independent predictors of adverse events, whereas high-sensitivity C-reactive protein day 1 and high-sensitivity C-reactive protein day 30 levels were not. Patients with interleukin-6 day 1≤8.24 pg/mL and interleukin-6 day 30≤4.45 pg/mL had the lowest event rates (4.7%), whereas those with both above the median values had the highest event rates (35%). After addition of interleukin-6 day 30 to the multivariate model, C-index increased from 0.71 (95% confidence interval, 0.63-0.78) to 0.80 (95% confidence interval, 0.72-0.86), P=.042, and net reclassification improvement was 0.39 (95% confidence interval, 0.14-0.64; P=.002). CONCLUSIONS In this population, both interleukin-6 and high-sensitivity C-reactive protein concentrations decreased after the acute phase. Serial samples of interleukin-6 concentrations improved the prognostic risk stratification of these patients.

Abstract
AIMS Patients with type 2 diabetes (T2DM) have a high restenosis rate after percutaneous coronary intervention (PCI). This study investigated whether markers of inflammation and the adipo-insular axis associated with T2DM and poor metabolic control were able to predict restenosis after PCI in T2DM patients. METHODS AND RESULTS The predictive value of traditional and non-traditional risk markers, including IL-1β, IL-6, TNF-α, hsCRP, interferon gamma, leptin, IGF-I, insulin, proinsulin and NT-proBNP, was investigated in 82 patients with T2DM. A re-angiography 6 months after the index percutaneous coronary intervention (PCI) revealed that 43% of the patients had a restenosis. In a multiple regression analysis, the only independent predictors of restenosis were fasting glucose before the PCI and previous myocardial infarction (odds ratio [OR] 1.44, 95% confidence interval [CI] 1.07-1.92; p = 0.015 and OR 8.00, 95% CI 2.49-25.67; p ≤ 0.001, respectively). None of the other markers remained as significant predictors. CONCLUSION Fasting glucose prior to the PCI was an independent predictor of restenosis in patients with T2DM while analyses of a variety of markers related to inflammation and the adipo-insular axis did not add any further information.

Abstract
The main adverse reactions to coronary stents are in-stent restenosis (ISR) and stent thrombosis. Along with procedural factors, individual susceptibility to these events plays an important role. In particular, inflammatory status, as assessed by C-reactive protein levels, predicts the risk of ISR after bare-metal stent implantation, although it does not predict the risk of stent thrombosis. Conversely, C-reactive protein levels fail to predict the risk of ISR after drug-eluting stent (DES) implantation, although they appear to predict the risk of stent thrombosis. Of note, DES have abated ISR rates occurring in the classical 1-year window, but new concern is emerging regarding late restenosis and thrombosis. The pathogenesis of these late events seems to be related to delayed healing and allergic reactions to polymers, a process in which eosinophils seem to play an important role by enhancing restenosis and thrombosis. The identification of high-risk individuals based on biomarker assessment may be important for the management of patients receiving stent implantation. In this report, we review the evolving role of inflammatory biomarkers in predicting the risk of ISR and stent thrombosis.

Abstract
C-reactive protein (CRP) elevation is associated with an adverse cardiovascular prognosis after bare metal stent implantation. Data have suggested a similar association between preprocedural CRP and adverse events after drug-eluting stent (DES) implantation. The present study was designed to address whether such a relation exists after DES placement. After excluding patients presenting with an acute coronary syndrome with troponin I elevation, we analyzed the data from 936 consecutive patients who had undergone DES implantation from 2003 to 2007 and had a preprocedural CRP measurement. The patients were divided into 3 groups according to the preprocedural CRP level (<1.31, 1.31-3.76, and >3.76 mg/L). The primary end point was the composite of death and Q-wave myocardial infarction (QWMI) at 2 years of follow-up. Target vessel revascularization was also assessed. The rate of death/QWMI was not significantly different statistically among the CRP tertiles during the in-hospital period (0.6% vs 0.0% vs 0.6%, p = 0.5) or at 1 year of follow-up (1.9% vs 2.9% vs 4.5%, p = 0.2). At 2 years, death/QWMI had occurred in 2.9% of patients in the lowest, 5.2% in the middle, and 8.8% in the highest tertile (p = 0.006). The incidence of target vessel revascularization was similar in the 3 groups at 2 years of follow-up (13.2% vs 14.9% vs 16.9%, p = 0.5). On multivariate analysis, the upper tertile of CRP was an independent predictor of death/QWMI at 2 years (hazard ratio 2.5, 95% confidence interval 1.1 to 5.4, tertile 3 vs tertile 1, p = 0.006). In conclusion, high preprocedural CRP levels are associated with an increased risk of death and QWMI after DES implantation at long-term follow-up but not acutely. The CRP levels were not related to target vessel revascularization. Thus, an elevated CRP level in this population appears to be more of a marker of global cardiovascular risk than a predictor of post-DES-related complications.

Abstract
During the last few decades, with the evolution of techniques and materials and the increasing experience of operators, percutaneous coronary interventions (PCI) have become an equally efficient alternative to coronary artery bypass grafts for the treatment of most coronary stenoses. Bare-metal stent implantation represented a major step forward, compared with plain old balloon angioplasty (POBA), by improving the immediate angiographic success. However, the incidence of in-stent restenosis (ISR) remained unacceptably high. Development of the drug-eluting stent (DES) significantly improved the outcome of PCI by dramatically abating the rate of ISR and reducing the incidence of target lesion revascularization. However, ISR has not been eliminated and the persistence of metal vessel scaffolding also raises concern regarding the occurrence of late or very late stent thrombosis. POBA and stent implantation have been shown to induce a local and systemic inflammatory response, whose magnitude is associated with worse clinical outcome, and they increase the risk of ISR. C-reactive protein, a marker of systemic inflammation, has been demonstrated to predict clinical and angiographic outcome after POBA or bare-metal stent implantation. However, conflicting data regarding the prognostic value of C-reactive protein following DES implantation are available. In this paper, we review the literature regarding the clinical and pathophysiological association between inflammation and prognosis after DES implantation and suggest some possible therapeutic approaches to reduce inflammatory burden with the aim to improve clinical and angiographic outcome after PCI.

Abstract
Initiation and progression of coronary atherosclerosis has been associated with inflammation and cytokines balance. The objective of this study is to understand the role of cytokines in the pathophysiology and management of coronary artery disease. Coronary artery disease has been revisited with revision of the pertinent published articles in the Medline, Scopus, and EBSCO Host research from 1987 to 2007. The 2 groups of cytokines (proinflammatory and anti-inflammatory) have been detected in human atherosclerotic plaques. The balance between the 2 groups may reflect the intensity of occult plaque inflammation and the vulnerability to rupture. Multiple studies have determined that a diverse set of proinflammatory biomarkers can furnish prognostic information beyond the traditional risk factors. Inflammatory responses after coronary revascularization are known to play key role in vascular lesion formation early in atherosclerosis and restenosis. Clinical utilization of cytokines remains promising yet incompletely explored and need more studies.

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
Stent implantation causes significant injury to the vascular wall, resulting in inflammatory activation. Although sirolimus-eluting stents (SES) have anti-inflammatory properties, their effect on periprocedural systemic inflammatory response has not been sufficiently investigated. Eighty-one patients with stable coronary artery disease involving severe stenosis of one major epicardial coronary artery underwent coronary angioplasty with stent implantation and randomly received either SES or bare metal stents (BMS). Blood samples were taken 24h before, at 24h, 48 h and 1 month after the angioplasty and levels of high sensitive C-reactive protein (hsCRP), interleukin-6 (IL-6), interleukin-1 beta (IL-1 beta), and monocyte chemoattractant protein-1 (MCP-1) were determined. HsCRP after BMS implantation increased over 24h (p<0.001) and then remained steady, as did IL-6 and IL-1 beta similarly. In contrast, their levels in SES patients decreased to below baseline by the end of the month. MCP-1 levels increased by the end of 1 month (p<0.001) in the BMS group, whereas in SES they steadily decreased, becoming significantly lower than baseline from 48 h (p=0.015). In conclusion, patients with SES exhibit an attenuation of the postprocedural systemic inflammatory activation during a 1-month follow-up after stent implantation. This might partially explain the reduced restenosis rate associated with SES.

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
OBJECTIVES The aims of this study were to investigate the effect of coronary stenting on the release of cytokines and cell-mediated immunity factors and to evaluate the association between inflammation and clinical outcomes at 6 months. BACKGROUND Circulating levels of inflammatory markers and cytokines are elevated in patients with acute coronary syndromes and are related to an unfavorable outcome. The aims of this study were to investigate the effect of coronary stenting on the release of cytokines and cell-mediated immunity factors and to evaluate the association between inflammation and clinical outcomes at 6 months. METHODS Forty patients with single native coronary artery disease treated with stenting were enrolled. Peripheral venous blood samples were collected before and 6 h, 48 h, and 12 weeks after stenting. Serum concentrations of high-sensitivity C-reactive protein, interleukin-6, interleukin-8, tumor necrosis factor-alpha (markers of inflammation) and serum-soluble interleukin-2 receptor for T-lymphocyte activation (sIL2-R, marker of cell-mediated immunity) were measured. Patients also were evaluated clinically one, 3, and 6 months post-stenting or when they presented with cardiovascular symptoms to identify major adverse cardiac events (cardiac death, MI, revascularization). RESULTS Concentrations of interleukins 6 and 8 and tumor necrosis factor-alpha peaked at 6 h (11.0, 12.6, and 5.3 pg/ml, respectively). The peak level of high-sensitivity C-reactive protein (2.77 mg/dL) occurred 48 h post stenting, while sIL2-R peaked (495 U/ml) at 12 weeks. Patients who experienced restenosis had higher levels of C-reactive protein at 48 h (4.94 vs. 1.84 mg/dl; P = 0.043) and of IL-8 at 6 h (26.75 vs. 13.55 pg/mL; P = 0.048) than those without restenosis. CONCLUSIONS Proinflammatory cytokines and inflammatory markers are released into the peripheral circulation early after coronary stenting, and increased levels of some are associated with clinically relevant restenosis.

Abstract
Implantation of coronary stents after percutaneous coronary intervention (PCI) may result in an inflammatory response with an increase in high sensitive C-reactive protein (Hs-CRP) and interleukin 6 (IL-6). In 25 patients Hs-CRP and IL-6 increased after coronary artery stenting, however, the increase in the inflammatory response did not differ between PES and BMS stents. The inflammatory response did not predict neointima hyperplasia measured by intravascular ultrasound after 6 months.

Abstract
OBJECTIVES Evidence of local vascular production and a relationship between serum hsCRP levels and tissue expression of CRP in subjects with vascular disease would support a direct role for CRP in atherosclerosis. METHODS AND RESULTS Vascular tissue from subjects undergoing coronary artery bypass grafting surgery (CABGS) (n=28) and carotid endarterectomy (CEA) (n=25) were studied. Histological samples were assessed for intima-media ratio (IMR) and CRP by immunohistochemistry. CRP mRNA was quantified by real-time polymerase chain reaction. CRP mRNA was seen in all plaques, non-atherosclerotic artery and atrium but no difference in mRNA expression was seen between plaque and non-atherosclerotic tissue. Serum hsCRP correlated with IMR (r=0.64, p=0.001) in non-atherosclerotic arteries and with plaque CRP staining (r=0.57, p=0.009) independent of age, BMI, lipids, diabetes and blood pressure. In a separate patient series, serum hsCRP was measured in aortic and coronary sinus blood from subjects undergoing CABGS or angiography (n=54). There was a coronary circulation hsCRP gradient ([mean+/-S.E.M.] aortic CRP 4.3mg/l+/-0.8 versus coronary sinus 5.8+/-1.2mg/l, p<0.05). CONCLUSIONS Widespread vascular CRP mRNA expression, a correlation between serum hsCRP, intimal hypertrophy and plaque CRP, and a coronary hsCRP gradient suggest vascular secretion may contribute to serum CRP levels.

Abstract
OBJECTIVE To determine the association of preprocedural C reactive protein (CRP) levels with angiographic restenosis and adverse clinical events after drug-eluting stent (DES) implantation. DESIGN A prospective cohort analysis of preprocedural CRP levels as a predictor of serious ischaemic complications or binary restenosis in patients treated with DES. SETTING Tertiary referral centre. PATIENTS 1650 consecutive patients who underwent successful DES implantation. Patients were grouped into tertiles according to preprocedural CRP values for data analysis. INTERVENTIONS Successful DES implantation. MAIN OUTCOME MEASURES The primary end point was a major coronary event, defined as cardiac death or Q-wave myocardial infarction. RESULTS Baseline clinical and angiographic characteristics were similar between the tertile groups, except that more patients had multivessel disease and acute coronary syndrome with increasing tertiles of CRP levels. At 1-year follow-up, a primary end point occurred in 4 (0.7%) patients of the lowest tertile, in 3 (0.5%) patients of the middle tertile and in 16 (2.9%) patients of the highest tertile (p = 0.003). In multivariate analysis, the highest tertile of CRP levels was an independent predictor of a major coronary event (HR 4.68, 95% CI 1.91 to 11.44, tertile III vs tertiles I and II, p = 0.001). However, restenosis rates were similar in all three groups (9.1% vs 11.4% vs 11.6%, respectively, p = 0.3). CONCLUSIONS Preprocedural CRP levels are significantly associated with major coronary events after DES implantation. However, preprocedural CRP levels do not predict subsequent restenosis. Baseline CRP levels may be useful to guide adjunctive management for preventing serious ischaemic events in patients undergoing DES implantation.

We report C-reactive protein (CRP) measured 1 month after stenting was an independent predictor of angiographic restenosis, and patients with both elevated preprocedural CRP and CRP 1 month after stenting had the worst long-term clinical outcomes. Measurement of CRP during follow-up in addition to preprocedural CRP may improve risk stratification after coronary stenting.

Abstract
BACKGROUND This study was performed to assess the relationship between oxidized low-density lipoprotein (OxLDL) and restenosis. OxLDL induces up-regulation of inflammatory genes and cytokines and recruits monocytes to the vessel wall. Elevated levels of monocytes post-percutaneous coronary intervention (PCI) are associated with in-stent restenosis. METHODS AND RESULTS One hundred forty-one patients with stable angina pectoris had serial blood samples drawn before PCI (68% balloon only, 32% stent), immediately post-PCI and at 6 and 24 hours, 3 days, 1 week, and 1, 3, and 6 months. Plasma levels of OxLDL-E06, a measure of oxidized phospholipid (OxPL) content on apoB-100 detected by antibody E06 (OxPL/apoB), autoantibodies to malondialdehyde-LDL and copper-oxidized LDL, and apoB-immune complexes were measured in all samples. Quantitative and qualitative coronary angiography was performed with 94% angiographic follow-up. Restenosis was defined as >50% diameter stenosis (%DS). The overall angiographic restenosis rate was 32% (39% in balloon group, 16% in stent group). OxPL/apoB levels rose significantly and OxLDL autoantibody titers decreased immediately post-PCI in patients both with and without restenosis, but there were no significant differences among groups. There was also no relationship of any OxLDL marker to lesion length, %DS, or minimal lumen diameter. No differences were noted in stent versus balloon-treated patients. CONCLUSIONS Serial measurement of a comprehensive panel of circulating OxLDL markers after uncomplicated PCI for stable angina does not predict restenosis.
