The relationships between biological novel biomarkers Lp-PLA 2 and CTRP-3 and CVD in patients with type 2 diabetes mellitus. J Diabetes 2024; 16:e13574. [PMID: 38924255 PMCID: PMC11199973 DOI: 10.1111/1753-0407.13574] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/18/2023] [Revised: 04/20/2024] [Accepted: 05/04/2024] [Indexed: 06/28/2024] Open
Abstract
BACKGROUND Cardiovascular disease (CVD) is recognized as a primary and severe comorbidity in patients with type 2 diabetes mellitus (T2DM) and is also identified as a leading cause of mortality within this population. Consequently, the identification of novel biomarkers for the risk stratification and progression of CVD in individuals with T2DM is of critical importance. METHODS This retrospective cohort study encompassed 979 patients diagnosed with T2DM, of whom 116 experienced CVD events during the follow-up period. Clinical assessments and comprehensive blood laboratory analyses were conducted. Age- and sex-adjusted Cox proportional hazard regression analysis was utilized to evaluate the association between lipoprotein-associated phospholipase A2 (Lp-PLA2), C1q/tumor necrosis factor-related protein 3 (CTRP-3), and the incidence of CVD in T2DM. The diagnostic performance of these biomarkers was assessed through receiver operating characteristic (ROC) curve analysis and the computation of the area under the curve (AUC). RESULTS Over a median follow-up of 84 months (interquartile range: 42 [32-54] months), both novel inflammatory markers, Lp-PLA2 and CTRP-3, and traditional lipid indices, such as low-density lipoprotein cholesterol and apolipoprotein B, exhibited aberrant expression in the CVD-afflicted subset of the T2DM cohort. Age- and sex-adjusted Cox regression analysis delineated that Lp-PLA2 (hazard ratio [HR] = 1.007 [95% confidence interval {CI}: 1.005-1.009], p < 0.001) and CTRP-3 (HR = 0.943 [95% CI: 0.935-0.954], p < 0.001) were independently associated with the manifestation of CVD in T2DM. ROC curve analysis indicated a substantial predictive capacity for Lp-PLA2 (AUC = 0.81 [95% CI: 0.77-0.85], p < 0.001) and CTRP-3 (AUC = 0.91 [95% CI: 0.89-0.93], p < 0.001) in forecasting CVD occurrence in T2DM. The combined biomarker approach yielded an AUC of 0.94 (95% CI: 0.93-0.96), p < 0.001, indicating enhanced diagnostic accuracy. CONCLUSIONS The findings suggest that the biomarkers Lp-PLA2 and CTRP-3 are dysregulated in patients with T2DM who develop CVD and that each biomarker is independently associated with the occurrence of CVD. The combined assessment of Lp-PLA2 and CTRP-3 may significantly augment the diagnostic precision for CVD in the T2DM demographic.

Exp Mol Med 2024; 56:1-18. [PMID: 38177294 PMCID: PMC10834487 DOI: 10.1038/s12276-023-01131-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2023] [Revised: 08/06/2023] [Accepted: 08/28/2023] [Indexed: 01/06/2024] Open
Abstract
Chitinase-3-like protein 1 (CHI3L1) is a secreted glycoprotein that mediates inflammation, macrophage polarization, apoptosis, and carcinogenesis. The expression of CHI3L1 is strongly upregulated by various inflammatory and immunological diseases, including several cancers, Alzheimer's disease, and atherosclerosis. Several studies have shown that CHI3L1 can be considered as a marker of disease diagnosis, prognosis, disease activity, and severity. In addition, the proinflammatory action of CHI3L1 may be mediated via responses to various proinflammatory cytokines, including tumor necrosis factor-α, interleukin-1β, interleukin-6, and interferon-γ. Therefore, CHI3L1 may contribute to a vast array of inflammatory diseases. However, its pathophysiological and pharmacological roles in the development of inflammatory diseases remain unclear. In this article, we review recent findings regarding the roles of CHI3L1 in the development of inflammatory diseases and suggest therapeutic approaches that target CHI3L1.

Abstract
Objective: This study intended to explore the serum YKL-40 change and its prognostic implication in acute ischemic stroke (AIS) patients with diabetes mellitus (DM). Methods: YKL-40 was detected from serum by ELISA in 121 AIS patients with DM at baseline, day (D)1, D3, D7 and D30 after disease onset. Results: YKL-40 increased from baseline to D3, then decreased until D30 (p < 0.001). Notably, 20.7% of patients had stroke recurrence, and 6.6% of patients died during follow-up. YKL-40 at D1 (p = 0.043), D7 (p = 0.007) and D30 (p = 0.001) predicted higher stroke recurrence risk; additionally, YKL-40 at D3 (p = 0.010), D7 (p = 0.007) and D30 (p = 0.002) estimated higher mortality risk. Conclusion: Serum YKL-40 has a prognostic effect on the management of AIS patients with DM.

[PMID: 35942210 PMCID: PMC9356854 DOI: 10.1155/2022/6137219] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2022] [Revised: 06/08/2022] [Accepted: 07/20/2022] [Indexed: 11/20/2022] Open
Abstract
This work is aimed at exploring the mechanism of inflammatory factors and soluble vascular cell adhesion molecule-1 (sVCAM-1) regulated by nuclear transcription factor-κB (NF-κB) in unstable angina pectoris (UAP). 60 patients with unstable angina pectoris (UAP), 60 patients with stable angina pectoris (SAP), and some healthy people (controls) were selected and included. Peripheral venous blood (PVB) of all subjects was collected to detect blood routine. The enzyme-linked immunosorbent assay (ELISA) was adopted for detecting Visfatin, sVCAM-1, soluble intervascular cell adhesion molecule-1 (sICAM-1), and inflammatory factors; flow cytometry (FCM) was to detect the CD63 and CD62P; real-time fluorescence quantitative polymerase chain reaction (rt-qPCR) was employed to detect the NF-κB1, NF-κB2, and REL mRNA. The hs-CRP results of UAP group, SAP group, and control group were 11.12 ± 1.5 mg/L, 10.23 ± 1.3 mg/L, and 4.51 ± 1.1 mg/L, respectively. The CD62P results of UAP group, SAP group, and control group were 16.07 ± 2.5%, 11.09 ± 1.8%, and 22.15 ± 0.4%, respectively. The high-sensitivity C-reactive protein (hs-CRP), inflammatory factors (IL-6, IL-17, IL-23, IL-1β, and tumor necrosis factor α (TNF-α)), CD63, CD62P, NF-κB1, NF-κB2, and REL mRNA were obviously higher in the SAP group compared than the indicator values in the control group (P < 0.05). The relative REL expression results of UAP group, SAP group, and control group were 3.77 ± 1.5, 2.2 ± 0.6, and 1 ± 0.4, respectively. The inflammatory factors, Visfatin, sVCAM-1, sICAM-1, CD63, CD62P, NF-κB1, NF-κB2, and REL mRNA in the UAP group showed higher levels in contrast to the other two groups (P < 0.05). In summary, UAP patients had marked activation of the IL-23/IL-17 inflammatory axis, high expressions of sVCAM-1 and sICAM-1, and activation of the NF-κB pathway. Increase of inflammatory factors and sVCAM-1 regulated by NF-κB was closely correlated with UAP.

Abstract
Aim This study attempted to investigate the diagnostic value of interleukin-18 (IL-18), matrix metalloproteinase-9 (MMP-9), high-sensitivity C-reactive protein (hs-CRP), and fibrinogen (FIB) in acute coronary syndrome (ACS) and their correlation with the degree of vascular lesions. Materials and Methods Altogether 206 patients with coronary heart disease admitted to our hospital were selected as research objects, including 136 patients with ACS (group A), 70 patients with stable angina pectoris (SAP) (group B), and 60 patients with noncoronary heart disease who had normal coronary angiography during the same period were selected as group C. The levels of IL-18, MMP-9, and hs-CRP in the serum were detected by enzyme-linked immunosorbent assay (ELISA), and the level of FIB in plasma was detected by automatic coagulation analyzer. Results Serum IL-18, MMP-9, hs-CRP, and plasma FIB levels in group A were significantly higher than those in group B and group C (p < 0.05). ROC curve and multivariate logistic regression showed that the sensitivity and specificity of combined diagnosis of ACS with serum IL-18, MMP-9, hs-CRP, and plasma FIB were 86.03% and 95.71%, respectively. Serum IL-18, MMP-9, hs-CRP, and plasma FIB were positively correlated with Gensini grading (p < 0.001). Serum IL-18, MMP-9, hs-CRP, and plasma FIB levels were positively correlated (p < 0.001). Conclusion The combined detection of serum IL-18, MMP-9, hs-CRP, and plasma FIB has good diagnostic value for ACS, and these index levels are positively correlated with the degree of vascular lesions.

Abstract
Abstract
Introduction: Systemic inflammation plays a key role in the pathophysiology of acute coronary syndrome (ACS), having a direct effect in promoting the progression and rupture of vulnerable coronary plaques. The aim of this study was to investigate the association between inflammatory biomarkers and the type of ACS (ST-elevation myocardial infarction – STEMI, non-ST-elevation myocardial infarction – NSTEMI, or unstable angina – UA) in patients with confirmed heart failure.
Material and Methods: This study included a total of 266 patients admitted to the Clinical Department of Cardiology of the County Emergency Clinical Hospital of Târgu Mureș – Cardiac Intensive Care Unit (CICU) for ACS of various types (UA, NSTEMI or STEMI) between January 1, 2017 and December 31, 2020, in whom the diagnosis of heart failure was established based on clinical and paraclinical data. From the total number of patients, 36 were hospitalized for UA and 230 for MI, of which 165 were STEMI and 65 were NSTEMI.
Results: Only hs-CRP and IL-6 were significantly higher in MI compared to UA. Mean hs-CRP was 4.9 ± 4.5 mg/mL in patients with UA vs. 20.4 ± 42.2 mg/mL in patients with MI (p = 0.001), and mean IL-6 was 7.2 ± 13.8 pg/mL in UA vs. 31.6 ± 129.2 pg/mL in MI (p <0.0001). ICAM seems to have had a greater discriminating power between STEMI and other types of ACS in those with heart failure, having a value more than double in those with STEMI (216.1 ± 149.6 ng/mL vs. 448.2 ± 754.4 ng/mL, p <0.0001).
Conclusions: In patients with heart failure, the increase of inflammatory biomarkers such as hs-CRP is associated with the development of an acute myocardial infarction but not with its type. Adhesion molecules, especially ICAM, are elevated in patients with STEMI compared to other types of ACS, indicating a potential role of endothelial alteration in the development of an ACS when it adds to systemic inflammation linked to heart failure.

Front Physiol 2021; 12:690109. [PMID: 34349665 PMCID: PMC8327173 DOI: 10.3389/fphys.2021.690109] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2021] [Accepted: 06/03/2021] [Indexed: 11/13/2022] Open
Abstract
Aim: Chitinase 3-like 1 (CHI3L1) has the potential to prompt proliferation and angiogenic formation. Interleukin-13 receptor α2 (IL-13Rα2) was regarded as a receptor of CHI3L1; however, it is unknown whether CHI3L1 adjusts the neovascularization in late atherosclerotic lesions of apoE -/- mice via IL-13Rα2. Methods: Silicone collars were placed around one of the common carotid arteries of apoE -/- mice fed with a high-fat diet. The mice were further injected with Ad.CHI3L1 alone or Ad.CHI3L1 + Ad.IL-13Rα2 shRNA through the caudal vein. The plaque areas in the whole aorta and aortic root were evaluated by Oil Red O staining and H&E staining. The contents of CD31, CD42b, and collagen in carotid plaques were investigated by immunohistochemistry and Masson trichrome staining. The role of CHI3L1 in migration and tube formation of human umbilical vein endothelial cells (HUVECs) was determined by transwell and Matrigel tests. The effect of CHI3L1 on the expression of AKT and extracellular signal-regulated kinase (ERK) was evaluated with the Western blot. Results: The plaque loads in the aorta were significantly more extensive in apoE -/- mice injected with Ad.CHI3L1 than those with Ad.CHI3L1 + Ad.IL-13Rα2 shRNA. CHI3L1 significantly increased the contents of CD31 and CD42b and decreased the element of collagen in late-stage atherosclerotic lesions of the carotid arteries. The effects of CHI3L1 on migration, tube formation, and upregulation of phospho-AKT and phospho-ERK of HUVECs were prohibited by inhibitors of phosphatidylinositol 3-kinase (PI3K) and mitogen-activated protein kinase kinase (MEK) as well as IL-13Rα2 shRNA. Conclusion: To some extent, CHI3L1 promotes migration and tube formation of HUVECs and neovascularization in atherosclerotic plaques possibly mediated by IL-13Rα2 through AKT and ERK signal pathways.

Abstract
PURPOSE This study aims to investigate the effects of ginkgo diterpene lactone on brain inflammation and oxidative stress in rats with cognitive impairment of cerebral small vessel disease (CSVD). METHODS We equally assigned 40 Sprague Dawley (SD) rats to the observation group (OG) and the control group (CG) and modeled them for cognitive impairment of CSVD. Rats in OG were given ginkgo diterpene lactone for treatment, while those in CG were injected with the same amount of normal saline. The learning and memorizing ability of rats was tested by the water maze. The oxidative stress and inflammatory response in rats were evaluated. The levels of vascular endothelial growth factor (VEGF) and endostatin (ES) mRNA in the hippocampus of rats were measured. Vascular smooth muscle cells of rats were sampled for cell viability and apoptosis assays. RESULTS Rats from OG were superior to those from CG in the learning and memorizing ability. After treatment, rats from OG had markedly lower malondialdehyde (MDA) levels and higher levels of superoxide dismutase (SOD), reduced glutathione (GSH), and glutathione peroxidase (GSH-Px) than those from CG (all P < 0.05). Concentrations of interleukin-18 (IL-18), transforming growth factor-β1 (TGF-β1), tumor necrosis factor-α (TNF-α), and amyloid β-protein 1-40 (Aβ1-40) were markedly lower in OG than in CG (all P < 0.05). Rats from OG had markedly higher VEGF levels and lower ES mRNA levels than those from CG (all P < 0.05). Cell viability gradually decreased in rats from OG after treatment and was markedly lower than that in rats from CG (P < 0.05). Cell apoptosis rate was markedly higher in OG than in CG (P < 0.05). CONCLUSION Ginkgo diterpene lactone can inhibit oxidative stress and inflammatory response in rats with cognitive impairment of CSVD to a certain degree.

Intensive statin versus low-dose statin + ezetimibe treatment for fibrous cap thickness of coronary vulnerable plaques. Chin Med J (Engl) 2021; 133:2415-2421. [PMID: 32889912 PMCID: PMC7575174 DOI: 10.1097/cm9.0000000000001067] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 02/01/2023] Open
Abstract
BACKGROUND Acute coronary syndromes mainly result from abrupt thrombotic occlusion caused by atherosclerotic vulnerable plaques (VPs) that suddenly rupture or erosion. Fibrous cap thickness (FCT) is a major determinant of the propensity of a VP to rupture and is recognized as a key factor. The intensive use of statins is known to have the ability to increase FCT; however, there is a risk of additional adverse effects. However, lower dose statin with ezetimibe is known to be tolerable by patients. The present study aimed to investigate the effect of intensive statin vs. low-dose stain + ezetimibe therapy on FCT, as evaluated using optical coherence tomography. METHOD Patients who had VPs (minimum FCT <65 μm and lipid core >90°) and deferred from intervention in our single center from January 2014 to December 2018 were included in the trial. They were divided into the following two groups: intensive statin group (rosuvastatin 15-20 mg or atorvastatin 30-40 mg) and combination therapy group (rosuvastatin 5-10 mg or atorvastatin 10-20 mg + ezetimibe 10 mg). At the 12-month follow-up, we compared the change in the FCT (ΔFCT%) between the two groups and analyzed the association of ΔFCT% with risk factors. Fisher exact test was used for all categorical variables. Student's t test or Mann-Whitney U-test was used for analyzing the continuous data. The relationship between ΔFCT% and risk factors was analyzed using linear regression analysis. RESULT Total 53 patients were finally enrolled, including 26 patients who were in the intensive statin group and 27 who were in the combination therapy group. At the 12-month follow-up, the serum levels of total cholesterol (TC), total triglyceride, low-density lipoprotein (LDL-C), hypersensitive C-reactive protein (hs-CRP), and lipoprotein-associated phospholipase A2 (Lp-PLA2) levels were reduced in both the groups. The ΔTC%, ΔLDL-C%, and ΔLp-PLA2% were decreased further in the combination therapy group. FCT was increased in both the groups (combination treatment group vs. intensive statin group: 128.89 ± 7.64 vs. 110.19 ± 7.00 μm, t = -9.282, P < 0.001) at the 12-month follow-up. The increase in ΔFCT% was more in the combination therapy group (123.46% ± 14.05% vs. 91.14% ± 11.68%, t = -9.085, P < 0.001). Based on the multivariate linear regression analysis, only the serum Lp-PLA2 at the 12-month follow-up (B = -0.203, t = -2.701, P = 0.010), ΔTC% (B = -0.573, t = -2.048, P = 0.046), and Δhs-CRP% (B = -0.302, t = -2.963, P = 0.005) showed an independent association with ΔFCT%. CONCLUSIONS Low-dose statin combined with ezetimibe therapy maybe provide a profound and significant increase in FCT as compared to intensive statin monotherapy. The reductions in Lp-PLA2, ΔTC%, and Δhs-CRP% are independently associated with an increase in FCT.

Abstract
Background: YKL-40, a secreted glycoprotein, has a role in promoting tumor angiogenesis through syndecan-1 receptor. Syndecan-4 is a member of syndecan family. However, the effects of YKL-40 on migration and tube formation of human umbilical vein cells (HUVECs) mediated by syndecan-4 receptor are unknown. Materials and methods: HUVECs were transfected with lentivirus encoding syndecan-4 short hairpin (sh) RNAs (lenti-synd4 shRNAs) and the efficiency of transfection was measured using qRT-PCR and western blotting. The effects of recombinant protein of YKL-40 on migration and angiogenesis of HUVECs adjusted by syndecan-4 were determined by wound healing and tube formation assay. The expressions of protein kinase Cα (PKCα) and extracellular signal regulated kinases (ERKs) 1 and 2 (ERK1/2) in HUVECs were measured using western blotting. Results: The mRNA and protein expression of syndecan-4 were significantly decreased in HUVECs successfully transfected with lenti-synd4 shRNAs. Lenti-synd4 shRNAs remarkably inhibited the migration and tube formation of HUVECs stimulated by recombinant protein of YKL-40. The levels of PKCα and ratio of p-ERK1/2 to ERK1/2 in HUVECs were also decreased by down-regulating syndecan-4. Conclusion: The effects of YKL-40 on migration and tube formation of HUVECs are partly inhibited by knock-downing syndecan-4 through suppressing PKCα and ERK1/2 signaling pathways.

Abstract
Patients with acute coronary syndrome (ACS) have an increased serum level of calprotectin. The purpose of present study was to analyze the prognostic significance of serum calprotectin levels in elderly diabetic patients underwent percutaneous coronary intervention (PCI) due to ACS.A total of 273 consecutive elderly diabetic patients underwent PCI for primary ACS were enrolled. Serum calprotectin levels were measured before PCI, and baseline clinical characteristics of all patients were collected. All patients were followed up at regular interval for major adverse cardiovascular events (MACEs) during 1 year after PCI. MACEs include cardiovascular death, nonfatal myocardial infarction, and target vessel revascularization (TVR). The predicting value of serum calprotectin for MACEs was analyzed by using univariate and multivariate analysis and receiver-operating characteristic curve (ROC).At the endpoint of this study, 47 patients of all 273 patients had MACEs. According to optimal cutoff value of calprotectin for predicting MACEs by ROC analysis, all patients were stratified into a high calprotectin group and a low calprotectin group. The incidence rate of MACEs and TVR in high calprotectin group was prominently higher than that in low calprotectin group (21.9% vs 11.5%, P = .02). In multivariable COX regression analysis adjusting for potential confounders, serum calprotectin level remains as an independent risk predictor of MACE (hazard ratio, 1.56; 95% confidence interval [CI]: 1.08-4.62; P = .01).In diabetic patients with a comorbidity of ACS, a high serum level of calprotectin is associated to a higher MACE rate after PCI.

Abstract
Background Coronary artery disease (CAD) remains a leading cause of morbidity and mortality. Cytokines play a potential role in atherosclerosis pathogenesis and progression. We investigated the association between high sensitive C-reactive protein (hsCRP) and severity of CAD. Methods CAD patients were stratified according to hsCRP cut-off value into high levels hsCRP group (≥ 8.4 mg/L) and low levels hsCRP group (< 8.4 mg/L). Severity of CAD was assessed according to artery stenosis degree and the number of vessel involved. Statistical analysis was performed using Statistical Package for the Social Sciences (SPSS, version 23.0). Results The mean age was 60.3 ± 11.0 years. The level of hsCRP was increased and ranged from 0.2 to 1020.0 mg/L. Biochemical risk factors and severity of CAD didn't show significant differences between the two groups. In multivariate linear analysis, cardiac troponin I (cTnI) and serum amyloid A (SAA) were predictors of hsCRP. As shown in receiver operating characteristic (ROC) curve analysis performed in patients with ST-segment elevation myocardial infarction (STEMI) and compared to myonecrosis biomarkers, hsCRP (area under the curve (AUC): 0.905; 95%CI: 0.844-0.966; P < 0.001) could be a powerful predictor marker in evaluating the infarct size after myocardial infarction but not better than cTnI. Conclusions HsCRP levels were not associated with the severity of CAD but could be useful in the evaluation of myocardial necrosis in patients with STEMI.

Abstract
Background Coronary flow is a determinative factor of non-ST-segment elevation myocardial infarction (NSTEMI) patients. Lipoprotein-Associated Phospholipase A2(Lp-PLA2) as a vascular specific inflammatory cytokine might relate to coronary slow flow in these patients. Methods 105 NSTEMI patients and 83 UAP patients were enrolled. Another group division was made by Lp-PLA2 tertile data. Corrected thrombolysis in myocardial infarction (TIMI) frame count (CTFC) was adopted to represent coronary flow condition. Correlation analysis was made between CTFC and other clinical indicators. Multivariable regression analysis was used to identify the influential factors of coronary flow in NSTEMI patients. ROC curve was used to determine the diagnostic value of Lp-PLA2 with coronary slow flow (CSF). Results High sensitive C reactive protein (hsCRP, P < 0.01), Lp-PLA2(P < 0.01), N-terminal pro-brain natriuretic peptide (NT-proBNP, P < 0.05), mean platelet volume (MPV, P<0.05), CTFC(P < 0.05) was higher in NSTEMI than UAP patients. hsCRP(P < 0.01), MPV(P < 0.01), NT-proBNP(P < 0.01) CTFC(P < 0.01) was higher in high-Lp-PLA2 group. Lp-PLA2 and hsCRP (r = 0.22, P < 0.01), MPV (r = 0.21, P < 0.05), CTFC (r = 0.69, P < 0.01) had a positive correlation in NSTEMI group. Multivariable regression analysis showed that Lp-PLA2 could explain most part changes of CTFC in NSTEMI patients, CTFC = 0.55*Lp-PLA2+0.03*hsCRP+0.005*NT-proBNP+15.843. Lp-PLA2 was specific and sensitive in diagnosis of CSF in NSTEMI group, AUC = 0.851(95% confidence interval (CI): 0.771-0.924, P < 0.01), Cutoff=196.96ng/ml, sensitivity = 84%, specificity = 81%. Conclusions Lp-PLA2 is closely correlated with coronary flow in NSTEMI patients. Lp-PLA2 over 196.96ng/ml could be used to predict CSF in NSTEMI patients.

Abstract
This study aimed to identify the correlation of contradiction between DAPT score and PRECISE-DAPT score with the severity of coronary lesion in acute coronary syndromes (ACS).In total, 458 patients with ACS after a percutaneous coronary intervention (PCI) who had tolerated 1-year uneventful dual antiplatelet therapy (DAPT) were enrolled and divided into groups based on the Gensini score, number of stenosed vessels, and left main (LM) disease. Both DAPT score and PRECISE-DAPT score were calculated and the proportion of patients receiving conflicting recommendations from each score was compared among the groups.DAPT score as well as the proportion of patients with DAPT score ≥2 were associated with the Gensini score and the number of stenosed vessels. Similarly, PRECISE-DAPT score as well as the proportion of patients with PRECISE-DAPT score ≥25 were associated with the Gensini score and the number of stenosed vessels. The proportion of patients with DAPT score ≥2 along with PRECISE-DAPT score ≥25 were associated with Gensini score, but they had no significant association with the number of stenosed vessels (P = .006 and P = .075, respectively). None of those aforementioned items were associated with LM disease.The inconsistencies of DAPT scores and PRECISE-DAPT scores are frequent and associated with the severity of coronary disease, represented by the Gensini score. Appropriate clinical decisions should be individualized.

Abstract
Background A retrospective study of data from a prospective clinical registry was conducted to evaluate the prognostic role of serum calprotectin in patients with diabetes who underwent percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS). Material/Methods Data were retrieved for 273 patients with diabetes mellitus who underwent PCI for primary ACS in a single center. Serum calprotectin levels were measured before PCI. Baseline clinical data included the Global Registry of Acute Coronary Events (GRACE) risk score for ACS. All patients underwent regular follow-up for major adverse cardiovascular events (MACE) during 12 months after PCI, including target vessel revascularization (TVR), defined as the need for an unplanned repeat PCI or coronary artery procedure. The predictive value of serum calprotectin for MACE was analyzed by using univariate and multivariate analysis and receiver operating characteristic (ROC) curve analysis. Results At the final follow-up, 47 of the 273 patients studies experienced MACE. Optimal cutoff values for serum calprotectin levels predictive for MACE stratified patients into a high calprotectin group and a low calprotectin group. The incidence of MACE and TVR in the high calprotectin group was significantly greater than in the low calprotectin group (21.9% vs. 11.5%; P=0.02). Multivariate analysis, adjusted for confounders, showed that the serum level of calprotectin was an independent risk factor for MACE (HR, 1.56; 95% CI, 1.08–4.62; P=0.01). Conclusions In patients with diabetes and the co-morbidity of ACS, a high serum level of calprotectin was associated with a significantly increased risk for MACE following PCI.

Abstract
Background Coronary heart disease is related to sudden death caused by multi-factors and a major threat to human health.This study explores the role of OX40L and ICAM-1 in the stability of coronary plaques and their relationship with sudden coronary death. Methods A total of 118 human coronary arteries with different degrees of atherosclerosis and/or sudden coronary death comprised the experimental group and 28 healthy subjects constituted the control group were isolated from patients. The experimental group was subdivided based on whether the cause of death was sudden coronary death and whether it was accompanied by thrombosis, plaque rupture, plaque outflow and other secondary changes: group I: patients with coronary atherosclerosis but not sudden coronary death, group II: sudden coronary death without any of the secondary changes mentioned above, group III: sudden coronary death with coronary artery atherosclerotic lesions accompanied by either of the above secondary changes. The histological structure of the coronary artery was observed under a light microscope after routine HE staining, and the related indexes of atherosclerotic plaque lesions were assessed by image analysis software. The expressions of OX40L and ICAM-1 were detected by real-time quantitative PCR (RT-PCR), immunohistochemistry (IHC) and Western blotting, and the correlations between the expressions and the stability of coronary atherosclerotic plaque and sudden coronary death were analyzed. Results (1) The expression of OX40L protein in the control group and the three experimental groups showed an increasing trend, and the difference between groups was statistically significant (P < 0.05). (2) The expression of the ICAM-1 protein in the control group and the three experimental groups showed a statistically significant (P < 0.05) increasing trend. (3) The expression of OX40L and ICAM-1 mRNAs increased in the control and the three experimental groups and the difference was statistically significant (P < 0.05). Conclusion The expression of OX40L and ICAM-1 proteins and mRNAs is positively correlated with the stability of coronary atherosclerotic plaque and sudden coronary death.

Abstract
YKL-40 is recently regarded as a pro-inflammatory cytokine involved in the pathological process of atherosclerosis and lipid metabolism. However, whether YKL-40 can directly influence the development of atherosclerosis and levels of lipid parameters is unknown. The aim of this study is to explore the effects of YKL-40 on atherosclerotic features, the levels of serum lipids, and biomarkers in apolipoprotein (E)-deficient (ApoE-/-) mice fed a high-fat diet. ApoE-/- mice were injected with a recombinant adenovirus expressing mouse YKL-40 or control adenovirus through the caudal vein. The levels of serum YKL-40, interleukin-6 (IL-6), tumour necrosis factor-alpha (TNF-alpha), matrix metalloproteinase-9 (MMP-9), and soluble vascular cell-adhesion molecule 1 (sVCAM-1) were measured by ELISA. Lipid metabolism parameters were measured using immunoturbidimetric assay. The size of plaque area in aorta was evaluated by Oil Red O and hematoxylin/eosin (HE) staining. The content of collagen fibers was stained with Masson, and the content of macrophages and smooth muscle cells (SMCs) in atherosclerotic lesions was investigated by immunohistochemistry. The serum levels of total cholesterol and triglycerides were similar between these two groups. Compared with the control, the levels of serum YKL-40, IL-6, TNF-alpha, MMP-9, plaque size, and macrophages in plaques were significantly increased in mice with adenovirus overexpressing YKL-40. However, the content of collagen fibers and SMCs was remarkably decreased in mice with adenovirus overexpressing YKL-40 than that in control. YKL-40 prompts the progress of atherosclerosis maybe involved with its role of pro-inflammation, but does not affect lipid metabolism in ApoE-/- mice fed a high-fat diet.

Abstract
ABSTRACT
Atrial fibrillation (AF) is an increasingly widespread healthcare problem. AF can frequently present as a complication in acute coronary syndromes (ACS), especially in ST-elevation acute myocardial infarction (AMI), in which case it is the most frequent supraventricular rhythm disturbance with an estimated incidence of 6.8-21%. The presence of AF in ACS heralds worse outcomes in comparison to subjects in sinus rhythm, and several studies have shown that in AMI patients, both new-onset and pre-existing AF are associated with a higher risk of major adverse cardiovascular and cerebrovascular events during hospitalization. The cause of newonset AF in AMI is multifactorial. Although still incompletely understood, the mechanisms involved in the development of AF in acute myocardial ischemic events include the neurohormonal activation of the sympathetic nervous system that accompanies the AMI, ischemic involvement of the atrial myocytes, ventricular dysfunction, and atrial overload. The identification of patients at risk for AF is of great significance as it may lead to prompt therapeutic interventions and closer follow-up, thus improving prognosis and decreasing cardiovascular and cerebrovascular events. The present manuscript aims to summarize the current research findings related to new-onset AF in AMI patients, as well as the predictors and prognostic impact of this comorbid association.
