Abstract
Successful reperfusion of myocardial tissue is the goal of primary percutaneous coronary intervention (pPCI) in patients with ST-segment elevation myocardial infarction (STEMI). We aimed to investigate the association between the De Ritis ratio (AST/ALT) and myocardial reperfusion in patients with STEMI who underwent pPCI. We retrospectively investigated 1236 consecutive patients who were hospitalized for STEMI and underwent pPCI. ST-segment resolution (STR) was defined as the return of the deviated ST-segment to baseline; poor myocardial reperfusion was defined as <70% STR. Patients were divided into 2 groups according to the median De Ritis ratio (.921); 618 patients (50%) were assigned to the De Ritis low group while 618 patients (50%) were assigned to the De Ritis high group. Stent size, neutrophil-to lymphocyte ratio (NLR), and the De Ritis ratio found to be associated with poor myocardial reperfusion (Odds ratio (OR) 1.45, 95% CI 1.07-1.98, P = .01, OR 1.22, 95% CI 1.01-1.48, P = .03 and OR 10.9, 95% CI 7.9-15, P < .001, respectively). A high De Ritis ratio was associated with poor myocardial reperfusion in STEMI patients who underwent pPCI. As an easily obtainable test in clinical practice, the De Ritis ratio may help identify patients at major risk for impaired myocardial perfusion.

Intramyocardial immunomodulation with human CD16 + monocytes to treat myocardial infarction in pig: a blind randomized preclinical trial. Front Cardiovasc Med 2024; 11:1427023. [PMID: 39171324 PMCID: PMC11335517 DOI: 10.3389/fcvm.2024.1427023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2024] [Accepted: 07/24/2024] [Indexed: 08/23/2024] Open
Abstract
Background Human CD16+ monocytes (hCD16+ Ms) have proangiogenic properties. We assessed the feasibility, safety and efficacy of hCD16+ Ms in a porcine model of myocardial infarction (MI). Methods and results A total of 27 female Large White pigs underwent MI with reperfusion and cardiac magnetic resonance (CMR). Five days later, animals received intramyocardial injections of hCD16+ Ms in saline (n = 13) or saline only (n = 14). hCD16+ Ms were selected from leucocyte cones. Feasibility/safety endpoints included injury at injected sites, malignant arrhythmias, cancer, haematoma, left ventricular (LV) dilatation, troponin release and downstream organ injury. Co-primary efficacy outcome included LV scar and ejection fraction (LVEF) at 30-day post-injections by CMR. Immunohistochemistry included neo-angiogenesis, fibrosis, markers of myofibroblast and inflammation. Four animals were excluded before injections due to untreatable malignant arrhythmias or lung injury. Median cell number and viability were 48.75 million and 87%, respectively. No feasibility/safety concerns were associated with the use of hCD16+ Ms. The LV scar dropped by 14.5gr (from 25.45 ± 8.24 to 10.8 ± 3.4 gr; -55%) and 6.4gr (from 18.83 ± 5.06 to 12.4 ± 3.9gr; -30%) in the hCD16+ Ms and control groups, respectively (p = 0.015). The 30-day LVEF did not differ between groups, but a prespecified sub-analysis within the hCD16+ Ms group showed that LVEF was 2.8% higher and LV scar 1.9gr lower in the subgroup receiving a higher cell dose. Higher tissue levels of neo-angiogenesis, myofibroblast and IL-6 and lower levels of TGF-β were observed in the hCD16+ Ms group. Conclusions The use of hCD16+ Ms in acute MI is feasible, safe and associated with reduced LV scar size, increased tissue levels of neo-angiogenesis, myofibroblasts and IL-6 and reduced pro-fibrotic TGF-β at 30-day post-injections. A higher cell dose might increase the LVEF effect while reducing scar size, but this warrants validation in future studies.

Abstract
Given the continuous changes in the world, with an increasing trend of unhealthy lifestyles, metabolic comorbidities, and increased susceptibility to cardiovascular diseases (CVDs), researchers change their attention to improve not only the therapeutic platform but also current CVD predictive and prognostic tools to improve disease outcomes. As CVD is characterized by an inflammatory paradigm involving, to some degree, the innate and adaptative immune systems, the neutrophil-to-lymphocyte ratio (NLR) emerged as a potential low-cost, rapidly available, and reliable inflammatory marker, with substantial recent evidence showing its potential utility in clinical practice. Thus, in this literature review, we will present an up-to-date discussion of the prognostic role of NLR in the most frequent CVDs, such as acute and chronic coronary disease, atherosclerotic disease, heart failure, cardiac valvopathies, and cardiac arrhythmias with predilection to atrial fibrillation.

Abstract
BACKGROUND Neutrophil to lymphocyte ratio (NLR) has been considered a prognostic biomarker of mortality and other major cardiac events. This study investigates NLR's efficacy in predicting in-hospital and long-term outcomes in patients with ST-segment elevated myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI). METHODS Electronic databases (PUBMED, Cochrane CENTRAL, ERIC, Embase, Ovid, and Google Scholar) were searched till June 2022 to identify studies having STEMI patients who underwent PCI. Risk ratios and mean differences (MDs), along with their corresponding 95% confidence intervals (Cis) and standard deviations (SDs), were pooled using a random-effect model. This meta-analysis has been registered on Prospero (ID: CRD42022344072). RESULTS A total of 35 studies with 28,756 patients were included. Pooled estimates revealed an increased incidence of primary outcomes; in-hospital all-cause mortality (RR = 3.52; 95% CI = 2.93-4.24), long-term all-cause mortality (HR = 1.07; 95% CI = 1.00-1.14), (RR = 3.32; 95% CI = 2.57-4.30); in-hospital cardiovascular mortality (RR = 2.66; 95% CI = 2.04-3.48), long-term cardiovascular mortality (RR = 6.67; 95% CI = 4.06-10.95); in-hospital major adverse cardiovascular events (MACE) (RR = 1.31; 95% CI = 1.17-1.46), long-term MACE (RR = 2.92; 95% CI = 2.16-3.94); length of hospital stay (WMD = 0.60 days; 95% CI = 0.40-0.79) in patients with high NLR compared to those with a low NLR. CONCLUSION NLR might be a valuable tool for prognostication (in-hospital) and stratification of patients with STEMI who underwent PCI.

Abstract
Myocardial infarction (MI), a leading cause of morbidity and mortality globally, is characterized by an underlying inflammatory process driven by atherosclerosis. The neutrophil-to-lymphocyte ratio (NLR), a readily available and cost-effective marker of systemic inflammation, has emerged as a potential predictor of adverse outcomes in patients with MI. This meta-analysis aimed to evaluate the association between elevated NLR and the risk of major adverse cardiovascular events (MACE) and all-cause mortality in patients with MI. A comprehensive literature search was conducted across multiple databases, including Embase, Web of Science, PubMed, and OVID Medicine, to identify relevant studies published from January 1, 2011, onward. Studies reporting the effect of NLR values on MACE and mortality in adult patients with MI, including both ST-elevation (STEMI) and non-ST-elevation (NSTEMI) subtypes, were included. Data extraction and quality assessment were performed independently by multiple authors. The meta-analysis included 37 studies, comprising a total of 18 studies evaluating the risk of MACE and 30 studies assessing all-cause mortality. The pooled analysis revealed a significantly increased risk of MACE (odds ratio [OR] 1.86, 95% confidence interval [CI] 1.53-2.28, P < 0.01) and all-cause mortality (OR 2.29, 95% CI 1.94-2.70, P < 0.01) in patients with elevated NLR compared to those without elevated NLR. Subgroup analyses stratified by follow-up duration and study design further supported the consistent association between elevated NLR and adverse outcomes. In conclusion, this meta-analysis demonstrates a significant association between elevated NLR and an increased risk of MACE and all-cause mortality in patients with MI. These findings highlight the potential clinical utility of NLR as a prognostic marker and underscore the importance of further research to validate its predictive value and establish optimal cutoff values for risk stratification in this patient population.

Abstract
Lipoprotein (a) [Lp(a)] could contribute to coronary artery disease (CAD) through proinflammatory effects. The neutrophil to lymphocyte ratio (NLR) is an inflammatory biomarker. We consecutively enrolled 7,922 CAD patients to investigate the synergistic association of Lp(a) and NLR with prognosis in patients undergoing percutaneous coronary intervention (PCI). NLR was calculated as the neutrophil count divided by the lymphocyte count. Cutoff for NLR was a median of 2.07. The threshold value was set at 30 mg/dL for Lp(a). The primary endpoint was major adverse cardiac events (MACEs), including all-cause mortality and myocardial infarction. During 2 years follow-up, 111 (1.40%) MACEs occurred. Lp(a) > 30 mg/dL was associated with an increased MACE risk in participants with NLR ≥2.07 [adjusted hazard ratio (HR), 1.84; 95% CI, 1.12-3.03], but not in participants with NLR <2.07 (adjusted HR, 0.74; 95% CI, 0.38-1.45) (Pinteraction = 0.021). Subgroup analysis demonstrated that the synergistic association of Lp(a) and NLR with prognosis was more pronounced in female patients (Pinteraction = 0.028). This study suggested that combining Lp(a) and NLR may be useful for risk stratification in CAD population.

Abstract
Despite extensive studies on endogenous heart regeneration within the past 20 years, the players involved in initiating early regeneration events are far from clear. Here, we assessed the function of neutrophils, the first-responder cells to tissue damage, during zebrafish heart regeneration. We detected rapid neutrophil mobilization to the injury site after ventricular amputation, peaking at 1-day post-amputation (dpa) and resolving by 3 dpa. Further analyses indicated neutrophil mobilization coincides with peak epicardial cell proliferation, and recruited neutrophils associated with activated, expanding epicardial cells at 1 dpa. Neutrophil depletion inhibited myocardial regeneration and significantly reduced epicardial cell expansion, proliferation, and activation. To explore the molecular mechanism of neutrophils on the epicardial regenerative response, we performed scRNA-seq analysis of 1 dpa neutrophils and identified enrichment of the FGF and MAPK/ERK signaling pathways. Pharmacological inhibition of FGF signaling indicated its' requirement for epicardial expansion, while neutrophil depletion blocked MAPK/ERK signaling activation in epicardial cells. Ligand-receptor analysis indicated the EGF ligand, hbegfa, is released from neutrophils and synergizes with other FGF and MAPK/ERK factors for induction of epicardial regeneration. Altogether, our studies revealed that neutrophils quickly motivate epicardial cells, which later accumulate at the injury site and contribute to heart regeneration.

Abstract
BACKGROUND Predicting the prognosis of primary percutaneous coronary intervention(PPCI) in ST-segment elevation myocardial infarction (STEMI) patients in the perioperative period is of great clinical significance. The inflammatory response during the perioperative period is also an important factor. This study aimed to investigate the dynamic changes in the systemic immune inflammatory index (SII) during the perioperative period of PPCI and evaluate its predictive value for in-hospital and out-of-hospital outcomes in patients with STEMI. METHODS This retrospective study included 324 consecutive patients with STEMI who were admitted to the cardiac care unit. Blood samples were collected before PPCI, 12 h (T1), 24 h, 48 h after PPCI, the last time before hospital discharge (T2), and 1 month after hospital discharge. The SII was calculated as (neutrophils×platelets)/lymphocytes. Based on whether the primary endpoint occurred, we divided the patients into event and non-event groups. Univariate and multivariate logistic regression analyses were performed to identify independent risk factors that might influence the occurrence of the primary endpoint. Dynamic curves of SII were plotted, and receiver operating characteristic (ROC) curves were drawn for each node to calculate the optimal critical value, sensitivity, and specificity to assess their predictive ability for in-hospital and out-of-hospital courses. Kaplan-Meier curves were used to analyze the differences in survival rates at different SII inflammation levels. RESULTS High levels of SII were individually related to the occurrence of the in-hospital period and long-term outcomes during the post-operative follow-up of STEMI patients (in-hospital SII: T1:OR 1.001,95%CI 1.001-1.001, P < 0.001; SII following hospital discharge: T1M: OR 1.008,95%CI 1.006-1.010, P < 0.001). Patients with high SII levels had lower survival rates than those with low SII levels. The analysis showed that the SII 12 h after (T1) and SII 1 month (T1M) had excellent predictive values for the occurrence of in-hospital and out-of-hospital outcomes, respectively (AUC:0.896, P < 0.001; AUC:0.892, P < 0.001). CONCLUSION There is a significant relationship between the dynamic status of SII and prognosis in patients with STEMI. This study found that the 12 h and SII 1 month affected in-hospital and out-of-hospital outcomes, respectively. Consequently, we focused on the dynamic changes in the SII.

Abstract
BACKGROUND Atherosclerosis is a progressive disease characterized by the build-up of lipids and connective tissue in the large arteries. Some patients experience chronic total occlusion (CTO). Inflammation plays a key role in the development and complications of atherosclerosis. Neutrophil-to-lymphocyte ratio (NLR) is a marker of systemic inflammation associated with the development of acute coronary syndrome (ACS). We aimed to assess the relationship between NLR and CTO in ACS patients with ST elevated myocardial infarction (STEMI) in Indonesia. METHODS This cross-sectional study was performed with secondary data obtained from patient medical records at Cipto Mangunkusumo National Central Hospital, Jakarta. Inclusion criteria were patients with ACS and STEMI who underwent coronary angiography in 2015-2018. RESULTS A total of 98 patients were enrolled in the analysis. Most subjects with CTO were male, elderly (> 60), smoking, had no history of diabetes mellitus (DM) or hypertension, no family history of coronary heart disease (CHD), but had a history of ACS and had never consumed statin or antiplatelet medications. Bivariate logistic regression analysis revealed that male gender (PR = 1.820; 95%CI 0.871-3.805; p = 0.025) and smoking (PR = 1.781; 95%CI 1.028-3.086; p = 0.004) were significantly correlated with CTO. Receiver operator characteristic (ROC) curve revealed that higher NLR (≥ 6.42) could predict a CTO diagnosis with positive predictive value (PPV) of 91%. Multivariate analysis revealed that NLR was correlated with an 11.2-fold increase in occurrence of CTO (95%CI 3.250-38.303; p < 0.001). Additionally, smoking was correlated with a 7-fold increase in CTO (95% CI 1.791-30.508; p = 0.006). CONCLUSION NLR value of ≥ 6.42 is potentially useful as a marker of CTO in STEMI patients. In addition, smoking increases the risk of CTO in ACS/STEMI patients.

Early long-term low-dosage colchicine and major adverse cardiovascular events in patients with acute myocardial infarction: a systematic review and meta-analysis. Front Cardiovasc Med 2023; 10:1194605. [PMID: 37608812 PMCID: PMC10440701 DOI: 10.3389/fcvm.2023.1194605] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Accepted: 07/24/2023] [Indexed: 08/24/2023] Open
Abstract
Background Current evidence on the efficacy and safety of colchicine after acute myocardial infarction (AMI) remains controversial. This study aims to clarify early low-dose long-term colchicine's exact efficacy and safety in AMI patients via more studies. Methods We searched PubMed, Web of Science, Embase, and Cochrane Library databases for randomized controlled trials assessing the efficacy of colchicine on major adverse cardiovascular events (MACE) in recent AMI patients from inception to January 29, 2023, without any restriction. Additionally, we conducted subgroup analyses to assess the impact of early (≤3 days) long-term (≥1 year) low-dosage (0.5 mg/d) colchicine. Summary estimates were computed using Mantel-Haenszel and reported as risk ratios (RRs) or standard mean differences (SMDs), mean differences (MDs) with 95% confidence intervals (CIs). Sensitivity analyses were performed to explore the potential sources of heterogeneity. Review Manager software was used for the meta-analysis. Results Eight studies identified from 564 screened records were analyzed, with 5,872 patients after AMI. The length of follow-up varied from five days to 22.7 months, and 0.5-1.0 mg colchicine was administered daily. In summary, compared to the control group, colchicine reduced the occurrence of MACE (RR, 0.56; 95% CI, 0.48-0.67) with 2.99-fold gastrointestinal adverse events in patients with recent AMI. Moreover, the relation referred to a gradual decrease in the occurrence of MACE with a longer follow-up duration (≥1 year) and lower dosage (0.5 mg/d) without leading more gastrointestinal adverse events. Colchicine decreased the follow-up levels of C-reactive protein (CRP) (MD -0.66, 95% CI, -0.98- -0.35) and neutrophils (SMD -0.22, 95% CI, -0.39- -0.55) when the follow-up period was 30 days. Conclusion Early long-term low-dose colchicine decreases the risk of MACE via anti-inflammation without leading more gastrointestinal adverse events in patients with AMI.

Abstract
OBJECTIVE The aim of the study is to compare the prognostic power of the BUN/albumin ratio (BAR) calculated on admission to the emergency department and the SYNergy between Percutaneous Coronary Intervention with TAXus (SYNTAX) score calculated after coronary angiography (CAG) in predicting 30-day mortality in patients with ST-segment elevation myocardial infarction (STEMI). METHOD AND MATERIAL The study was conducted prospectively between March 2021 and March 2022 in the emergency department of a tertiary hospital. Patients over the age of 18 who underwent CAG with a diagnosis of STEMI were included in the study. Demographic charecteristics, comorbidities, laboratory parameters of the patients at the time of admission and SYNTAX (SX) score were recorded in the data form. RESULTS A total of 1147 patients (77% male) diagnosed with STEMI were included in the study. When the receiver-operating characteristic analysis for SX score and laboratory parameters' power to predict mortality was examined, it was found that the AUC value of the BAR level (AUC: 0.736; 95% confidence interval: 0.670-0.802, P < 0.001) was the highest. If the threshold value of the serum BAR level, which was determined to predict mortality, was taken as 4, the sensitivity was found to be 76.7% and the specificity was 56.9%. With multivariate logistic analysis, it was determined that the risk of mortality increased by 1.25 for each unit increase in the BAR value in STEMI patients ( P < 0.001). CONCLUSION According to the study data, the BAR may guide the clinician in the early period as a practical and valuable predictor of 30-day mortality in patients diagnosed with STEMI.

Abstract
BACKGROUND The ratio of platelets to lymphocytes (PLR) can serve as a potential biomarker for predicting the prognosis of individuals with acute myocardial infarction (AMI). AIM The purpose of the research was to evaluate the in-hospital outcomes of AMI patients and the predictive significance of PLR on major adverse cardiac events (MACE). METHODS A total of 799 AMI patients who had successful primary PCI within 12 h of the onset of chest pain were separated into low PLR (n = 511) and high PLR (n = 288) groups using a PLR cutoff value of 178. At admission, total white blood cell, neutrophil, lymphocyte, and platelet counts were assessed. RESULTS In patients with a high PLR group with PLR > 178, the incidence of MACE: heart rupture, acute heart failure, total adverse events, and mortality due to all events was considerably greater. In an analysis of the receiver operating characteristic curve, a high PLR > 178 accurately predicted adverse outcomes (73% specificity and 65% sensitivity). Age, hypertension, and PLR were found as independent predictors of adverse outcomes by multiple logistic regression. CONCLUSIONS AMI patients with high PLR had poor hospital outcomes. These findings recommend PLR as an independent risk factor for hospital-acquired complications, suggesting that inflammation and prothrombotic state may contribute to the poor prognosis of high PLR patients.

Abstract
In this study, we aimed to evaluate the utility of the immune-inflammation index (SII) in estimating the no-reflow phenomenon and short-term cardiovascular prognosis in patients with ST-segment elevation myocardial infarction (STEMI). 723 consecutive patients with STEMI who underwent primary percutaneous coronary intervention (PCI) were enrolled in our study. The receiver-operating characteristics (ROC) curve was used to determine the cut-off value of SII to predict the no-reflow. The multivariate regression analysis analyzed the correlation between no-reflow and SII. The median value of SII was significantly higher in patients with no-reflow in comparison with normal reperfusion [1466 (939-2409) vs 905 (566-1379), p < .001]. The optimal threshold for SII in predicting the no-reflow phenomenon was 1036, with sensitivity and specificity of 70% and 59%, respectively. The area under the ROC curve (AUC) was 0.71 (95% CI, 0.66-0.75, p < .001). In multivariate analysis, SII ≥ 1036 value showed an independent predictive value for the no-reflow (OR = 0.51, 95% CI: 0.29-0.92, p = .02) and the 30-day cardiovascular mortality (OR = 2.37, 95% CI: 1.34-4.19, p = .003). Our results suggest that higher SII levels are independently associated with the no-reflow phenomenon and 30-day mortality in STEMI patients undergoing primary PCI.

Abstract
Introduction. Chronic inflammation plays an essential role in the pathophysiology of both arterial hypertension (HTN) and coronary artery disease (CAD), and is more pronounced in individuals with a non-dipper circadian blood pressure (BP) pattern. A non-dipping BP pattern is in turn is associated with increased cardiovascular morbi-mortality, and a higher risk of atherosclerotic events. Neutrophil to lymphocyte ratio (NLR), monocyte to lymphocyte ratio (MLR) and platelet to lymphocyte ratio (PLR) are readily available predictors of systemic inflammation and cardiovascular risk. The purpose of our study is to evaluate whether NLR, MLR and PLR can be used as cost-effective predictors of a non-dipping blood pressure pattern in hypertensive patients with stable CAD. Materials and Methods: We performed a cross-sectional retrospective analysis that included 80 patients with hypertension and stable CAD (mean age 55.51 ± 11.83 years, 71.3% male) referred to a cardiovascular rehabilitation center. All patients underwent clinical examination, 24 h ambulatory blood pressure monitoring (ABPM) and standard blood analysis. Results: Baseline demographic characteristics were similar in both groups. Patients with non-dipper pattern had significantly higher NLR (median = 2, IR (2–3), p < 0.001), MLR (median = 0.31, IR (0.23–0.39), p < 0.001) and PLR (median = 175, IR (144–215), p < 0.001) compared to dippers. Conclusion: Our results suggest that MLR and PLR are inexpensive and easily accessible biomarkers that predict a non-dipping pattern in hypertensive patients with stable CAD.

Abstract
Abstract
Introduction: Severe ischemia occurring in the lower limbs represents the advanced stage of peripheral artery disease (PAD). Atherosclerosis and inflammatory markers have been intensively studied to identify prognostic tools with a role in the evolution of patients with PAD. The aim of this study is to demonstrate the predictive value of systemic inflammatory markers such as the neutrophil-to-lymphocyte ratio (NLR) and the systemic inflammation index (SII) in the prognosis of patients diagnosed with critical leg ischemia (CLI) undergoing infrainguinal surgical revascularization with remote endarterectomy.
Materials and methods: This retrospective study included all patients admitted to the Vascular Surgery Clinic of the County Emergency Clinical Hospital of Târgu Mureș, Romania between January 2018 and December 2021, who had critical limb ischemia Leriche-Fontaine stage III and were treated with endarterectomy. Patients were divided into two groups based on the presence or absence of patency in the lower limbs at 12 months.
Results: There was a higher baseline value of neutrophil count (p <0.0001), platelet count (p = 0.006), NLR and SII value (p <0.0001), as well as a lower value of lymphocyte count (p = 0.001) in the group without patency at 12 months. The ROC curve analysis showed that the NLR and SII were associated with the risk of major amputation and primary patency failure at 12 months, while multivariate analysis has shown that arterial hypertension (OR 3.63, p = 0.04), history of myocardial infarction (OR 2.93, p = 0.009), diabetes mellitus (OR 2.20; p = 0.04) and smoking (OR 3.48, p <0.0001) were also predictors of primary patency failure.
Conclusions: The results of this study demonstrated the predictive role of NLR and SII regarding poor outcomes among patients with CLI Leriche-Fontaine stage III undergoing infrainguinal surgical revascularization with remote endarterectomy.

Abstract
OBJECTIVES Neutrophil-to-lymphocyte ratio (NLR), one of the composite biomarker of systemic inflammatory status, was proved promising in predicting clinical outcomes of acute coronary syndrome (ACS). However, there were no evidences that NLR was directly relative to the clinical outcomes of unstable angina pectoris (UAP). Therefore, this study was aimed to detect whether NLR could predict the coronary artery lesion severity (indicated as SYNTAX score) and clinical outcomes (especially long-term cardiovascular mortality) in patients with. METHODS In the single-centre retrospective study, 4110 patients with UAP were enrolled and divided into two groups according to their primary NLR values and followed up at a median time duration of 36 months. The differences of SYNTAX score and cardiovascular mortality between groups were analysed, and the predictive value of NLR was determined. RESULTS NLR was positively and linearly correlated with SYNTAX score (r = 0.270). Diabetes (p = 0.049), lymphocyte (p = 0.004), NLR (p = 0.002) and SYNTAX score (p < 0.001) were independent predictors of long-term cardiovascular mortality in patients with UAP. Kaplan-Meier analysis revealed higher occurrence of cardiovascular mortality when NLR > 2.38 (p = 0.015). Receiver operating characteristic (ROC) analysis showed that NLR = 2.76 is an effective cut point for predicting cardiovascular mortality (69.2% sensitivity, 64.8% specificity). CONCLUSIONS NLR value was positively related to the severity of coronary artery lesion and proved to be an independent predictor of cardiovascular mortality in patients with UAP. This study would contribute to therapy and prognosis optimisation of UAP.

Abstract
Background and Objectives: Functional capacity (FC) assessed via cardiopulmonary exercise testing (CPET) is a novel, independent prognostic marker for patients with coronary artery disease (CAD). Neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) are two readily available predictors of systemic inflammation and cardiovascular event risk, which could be used as cost-effective predictors of poor FC. The purpose of this study was to evaluate the utility of NLR and PLR in predicting poor FC in patients with CAD and recent elective percutaneous coronary intervention (PCI). Materials and Methods: Our cross-sectional retrospective analysis included 80 patients with stable CAD and recent elective PCI (mean age 55.51 ± 11.83 years, 71.3% male) who were referred to a cardiovascular rehabilitation center from January 2020 to June 2021. All patients underwent clinical examination, cardiopulmonary exercise testing on a cycle ergometer, transthoracic echocardiography and standard blood analysis. Results: Patients were classified according to percent predicted oxygen uptake (% VO2 max) in two groups—poor FC (≤70%, n = 35) and preserved FC (>70%, n = 45). There was no significant difference between groups regarding age, gender ratio, presence of associated comorbidities, left ventricular ejection fraction and NLR. PLR was higher in patients with poor FC (169.8 ± 59.3 vs. 137.4 ± 35.9, p = 0.003). A PLR cut-off point of 139 had 74% sensitivity and 60% specificity in predicting poor FC. After multivariate analysis, PLR remained a significant predictor of poor functional status. Conclusions: Although CPET is the gold standard test for assessing FC prior to cardiovascular rehabilitation, its availability remains limited. PLR, a cheap and simple test, could predict poor FC in patients with stable CAD and recent elective PCI and help prioritize referral for cardiovascular rehabilitation in high-risk patients.

Abstract
Background The neutrophil–lymphocyte ratio (NLR) is emerging as an important biomarker of acute physiologic stress in a myriad of medical conditions, and is a confirmed poor prognostic indicator in COVID-19. Objective We sought to describe the role of NLR in predicting poor outcome in COVID-19 patients undergoing mechanical thrombectomy for acute ischemic stroke. Methods We analyzed NLR in COVID-19 patients with large vessel occlusion (LVO) strokes enrolled into an international 12-center retrospective study of laboratory-confirmed COVID-19, consecutively admitted between March 1, 2020 and May 1, 2020. Increased NLR was defined as ≥7.2. Logistic regression models were generated. Results Incidence of LVO stroke was 38/6698 (.57%). Mean age of patients was 62 years (range 27–87), and mortality rate was 30%. Age, sex, and ethnicity were not predictive of mortality. Elevated NLR and poor vessel recanalization (Thrombolysis in Cerebral Infarction (TICI) score of 1 or 2a) synergistically predicted poor outcome (likelihood ratio 11.65, p = .003). Patients with NLR > 7.2 were 6.8 times more likely to die (OR 6.8, CI95% 1.2–38.6, p = .03) and almost 8 times more likely to require prolonged invasive mechanical ventilation (OR 7.8, CI95% 1.2–52.4, p = .03). In a multivariate analysis, NLR > 7.2 predicted poor outcome even when controlling for the effect of low TICI score on poor outcome (NLR p = .043, TICI p = .070). Conclusions We show elevated NLR in LVO patients with COVID-19 portends significantly worse outcomes and increased mortality regardless of recanalization status. Severe neuro-inflammatory stress response related to COVID-19 may negate the potential benefits of successful thrombectomy.

Abstract
Background Neutrophils are involved in the injury of myocytes during myocardial ischemia (MI). Stem cells migrate to the site of myocardial injury under homing signals and play a protective role, such as inhibiting inflammation. Chemokine SDF-1α and its related receptor CXCR4 are upregulated after myocardial infarction, which may play an important role in stem cell homing. Objectives This study aimed to explore the potential therapeutic effect of SDF-1α-modified bone marrow mesenchymal stem cells on myocardial ischemia/reperfusion (I/R) injury. Methods We explored the role of SDF-1α modified bone marrow mesenchymal stem cells in vivo and in vitro. SDF-1α and CXCR4 expression was detected under hypoxia/reoxygenation (H/R) condition. Cell migration was detected by the transwell method. The levels of SDF-1α and IL-1β, IL-6, IL-10, and TNF-α were detected in different groups. Results In vivo, SDF-1α was mainly upregulated and secreted by cardiomyocytes, and cardiomyocytes recruited stem cells through the SDF-1/CXCR4 pathway to reduce the damage of polymorphic mononuclear neutrophils to cardiomyocytes under H/R. Upregulation of SDF-1α increased the migration ability of BMSC Stem Cells to H/R-induced cardiomyocytes. In vitro, intravenous injection of SDF-1α gene-modified BMSC Stem Cells reduced inflammatory infiltration in the injured area as well as the level of systemic inflammatory factors. Conclusions SDF-1α-overexpressing BMSC Stem Cells protected the heart function of mice and significantly reduced I/R-induced myocardial injury, which has a potential protective effect on MI.

Abstract
The natural history of coronary heart disease (CAD) commonly begins with atherosclerosis, progressing to chronic coronary syndrome (CCS), acute coronary syndrome (ACS), and eventually, heart failure. Despite advancements in preventive and therapeutic strategies, there is room for further cardiovascular risk reduction. Recently, inflammation has emerged as a potential therapeutic target. The neutrophil-to-lymphocyte ratio (NLR) is a novel inflammatory biomarker which predicts poor prognosis in several conditions such as metabolic syndrome, sepsis, malignancy and CAD. In atherosclerosis, a high NLR predicts plaque vulnerability and severe stenosis. This is consistent with observations in CCS, where an elevated NLR predicts long-term major adverse cardiac events (MACEs). In ACS patients, high NLR levels are associated with larger infarct sizes and poor long-term outcomes. Possible reasons for this include failure of fibrinolysis, ischemia-reperfusion injury and in-stent restenosis, all of which are associated with raised NLR levels. Following myocardial infarction, an elevated NLR correlates with pathological cardiac remodeling which propagates chronic heart failure. Finally, in heart failure patients, an elevated NLR predicts long-term MACEs, mortality, and poor left ventricular assist device and transplant outcomes. Further studies must evaluate whether the addition of NLR to current risk-stratification models can better identify high-risk CAD patients.

Abstract
Innate and adaptive leukocytes rapidly mobilize to ischemic tissues after myocardial infarction in response to damage signals released from necrotic cells. Leukocytes play important roles in cardiac repair and regeneration such as inflammation initiation and resolution; the removal of dead cells and debris; the deposition of the extracellular matrix and granulation tissue; supporting angiogenesis and cardiomyocyte proliferation; and fibrotic scar generation and resolution. By organizing and comparing the present knowledge of leukocyte recruitment and function after cardiac injury in non-regenerative to regenerative systems, we propose that the leukocyte response to cardiac injury differs in non-regenerative adult mammals such as humans and mice in comparison to cardiac regenerative models such as neonatal mice and adult zebrafish. Specifically, extensive neutrophil, macrophage, and T-cell persistence contributes to a lengthy inflammatory period in non-regenerative systems for adverse cardiac remodeling and heart failure development, whereas their quick removal supports inflammation resolution in regenerative systems for new contractile tissue formation and coronary revascularization. Surprisingly, other leukocytes have not been examined in regenerative model systems. With this review, we aim to encourage the development of improved immune cell markers and tools in cardiac regenerative models for the identification of new immune targets in non-regenerative systems to develop new therapies.

Abstract
OBJECTIVE The aim: We have aimed to develop method of risk assessment in patients with acute STEMI using blood cells count useful in everyday clinical practice. PATIENTS AND METHODS Materials and methods: 317 STEMI patients admitted to ICCU starting at 01/2014 to 06/2020 were included in this study. Data were evaluated partially retrospectively (n=214), 1st group) and prospectively, applying new risk-assessment tool in 103 patients 2nd group). Study groups did not differ in terms of all clinical characteristics. RESULTS Results: To evaluate criteria of severity of in-hospital complication we have created in-hospital complication index (HCI), composed according to number of adverse events per patient. Based on correlation analyses we have composed complex WBC-platelets (WBC-PLT) index = ((GRA - MON) / LYM) · 10 + PDWc + P-LCR). In the 1st study group WBC-PLT index was associated with in-hospital complications' index and correlated with neutrophil-leukocytes ratio (NLR) (p<0,001 and p<0,0005 respectively). WBC-PLT index > 137 appeared to be mildly associated with increased risk of adverse in-hospital outcomes (with specificity of 78 % and low sensitivity of 64 %, AUC- 0,72). Further prospective study of WBC-PLT index measured on the first STEMI-day (group 2) revealed that this parameter was more informative regarding association with adverse in-hospital events whereas NLR had low accuracy in risk assessment. CONCLUSION Conclusions: WBC-PLT index assessed on the first STEMI day may be used as a tool for detection of patients at risk of adverse in-hospital events in the every-day clinical practice.

Abstract
BACKGROUND: Acute coronary syndrome (ACS) patients with chronic kidney disease (CKD) are known to have a higher risk of mortality compared to ACS patients without CKD. In ACS patients with CKD, chronic inflammation plays an important role in morphological and functional changes in endothelial cells, resulting in atherosclerosis acceleration associated with coronary severity that leads to an increase in major adverse cardiac events (MACE).
AIM: Therefore, this study aims to determine the role of neutrophil lymphocyte ratio (NLR) as a predictor of MACE and its correlation with coronary severity in ACS patients with CKD.
METHODS: The study was conducted at National General Hospital Cipto Mangunkusumo Jakarta, Indonesia in October to November 2019. We used quota sampling with two designs study. First, a nested case control study was conducted with a total of 59 ACS patients with CKD: 31 subjects who had experienced MACE as a case group and 28 subjects who had not experienced MACE as a control group. Second, a correlative study with a cross-sectional approach was undertaken.
RESULTS: There was no significant difference or relationship between NLR and MACE (p > 0.05; OR = 2.16 [95% CI = 0.63–7.51]), also no correlation between NLR and coronary severity degree assessed using the Gensini score (r = 0.10; p = 0.474).
CONCLUSION: NLR can not predict MACE in ACS patients with CKD nor be employed interchangeably with the Gensini score in assessing coronary severity in ACS patients with CKD.

Abstract
INTRODUCTION Heart failure (HF) secondary to acute myocardial infarction (AMI) is still a worldwide problem with a high mortality rate. The current study aimed to explore early and reliable predictive biomarkers of HF following AMI. METHODS The gene expression profile GSE59867 was downloaded from GEO. Array data from peripheral blood mononuclear cells (PBMCs) was used from 46 control patients and 111 patients with AMI at four time points: (i) first day of AMI; (ii) 4-6 days after AMI; (iii) one month after AMI; and (iv) six months after AMI. Among the 111 AMI patients, nine with HF and eight without HF were studied. CIBERSORT was used to analyze the relative proportions of immune cells in PBMCs. The proportions of immune cells in different groups were compared. Differentially expressed genes (DEGs) were analyzed with R language packages. RESULTS The percentages of monocytes and neutrophils increased significantly on the first day of AMI, and then decreased gradually. The percentage of regulatory T cells increased significantly 4-6 days after AMI, while the percentage of resting memory CD4 cells, CD8 T cells, and resting natural killer cells decreased significantly on the first day of AMI, and then increased gradually. Patients who developed HF had a significantly higher proportion of neutrophils in PBMCs on the first day of AMI, but had a significantly lower proportion of naive CD4 T cells. Two shared genes, interleukin-1 receptor 2 (IL1R2) and leucine-rich repeat neuronal protein 3 (LRRN3), were found to have potentially important roles in predicting the development of HF following AMI. CONCLUSION A higher proportion of neutrophils and a lower proportion of naive CD4 T cells in PBMCs on the first day of AMI may be correlated with the development of HF following AMI. IL1R2 and LRRN3 may exert functions in the development of HF following AMI.

Abstract
Background: Inflammation plays an important role in the pathogenesis of diseases such as atherosclerosis and other inflammatory disorders. The inflammatory markers impose a considerable cost on the health system. Recently, neutrophil to lymphocyte ratio (NLR) has been shown to be involved in the prediction of coronary artery disease (CAD). Objectives: This study was conducted to clarify the potential relationship between NLR and the inflammatory extent of CAD. Materials and Methods: Patients with ST-elevation myocardial infarction (STEMI) or stable angina who underwent primary or elective percutaneous coronary intervention (PCI), respectively, were included in this cross-sectional study. Patients with hematologic disorders, recent or active infectious or inflammatory diseases, history of malignancy, and history of treatment with immunosuppressive drugs were excluded from the study. Gensini and SYNTAX scores were calculated for each patient as an indicator of the extent of CAD. Demographic and clinical characteristics were obtained through a questionnaire and NLR was calculated using laboratory results. Results: A total of 446 patients (223 patients in each group) fulfilled the inclusion criteria. NLR had a significant relationship with Gensini score in both stable angina and STEMI patients. Gensini and SYNTAX scores correlated significantly with NLR; however, the correlation was weaker for SYNTAX score. After adjustment for confounding factors, including age and hypercholesterolemia, only one trend remained for the Gensini scores. Conclusion: NLR showed a stronger correlation with Gensini score than SYNTAX score. Our findings are in accordance with previous studies, which show that NLR has a relationship with the extent of CAD. Further studies are required for reaching a definite conclusion. The idea of this study may be useful for the investigation of other inflammatory diseases.

Abstract
Objective: Systemic inflammation after subarachnoid hemorrhage (SAH) is implicated in delayed cerebral ischemia (DCI) and adverse clinical outcomes. We hypothesize that early changes in peripheral leukocytes will be associated with outcomes after SAH. Methods: SAH patients admitted between January 2009 and December 2016 were enrolled into a prospective observational study and were assessed for Hunt Hess Scale (HHS) at admission, DCI, and modified Ranked Scale (mRS) at discharge. Total white blood cell (WBC) counts and each component of the differential cell count were determined on the day of admission (day 0) to 8 days after bleed (day 8). Global cerebral edema (GCE) was assessed on admission CT, and presence of any infection was determined. Statistical tests included student's t-test, Chi-square test, and multivariate logistic regression (MLR) models. Results: A total of 451 subjects were analyzed. Total WBCs and neutrophils decreased initially reaching a minimum at day 4–5 after SAH. Monocyte count increased gradually after SAH and peaked between day 6–8, while basophils and lymphocytes decreased initially from day 0 to 1 and steadily increased thereafter. Neutrophil to lymphocyte ratio (NLR) reached a peak on day 1 and decreased thereafter. WBCs, neutrophils, monocytes, and NLR were higher in patients with DCI and poor functional outcomes. WBCs, neutrophils, and NLR were higher in subjects who developed infections. In MLR models, neutrophils and monocytes were associated with DCI and worse functional outcomes, while NLR was only associated with worse functional outcomes. Occurrence of infection was associated with poor outcome. Neutrophils and NLR were associated with infection, while monocytes were not. Monocytes were higher in males, and ROC curve analysis revealed improved ability of monocytes to predict DCI and poor functional outcomes in male subjects. Conclusions: Monocytosis was associated with DCI and poor functional outcomes after SAH. The association between neutrophils and NLR and infection may impact outcomes. Early elevation in monocytes had an improved ability to predict DCI and poor functional outcomes in males, which was independent of the occurrence of infection.

NAN FANG YI KE DA XUE XUE BAO = JOURNAL OF SOUTHERN MEDICAL UNIVERSITY 2021; 41:870-875. [PMID: 34238739 PMCID: PMC8267992 DOI: 10.12122/j.issn.1673-4254.2021.06.09] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Subscribe] [Scholar Register] [Received: 12/10/2020] [Indexed: 11/24/2022]
Abstract
OBJECTIVE To investigate the role of PI3K/Akt signaling pathway in mediating the protective effect of endomorphin-1 against myocardial ischemia-reperfusion (IR) injury. OBJECTIVE Fifty SD male rats were randomly divided into sham operation group, myocardial IR group, endomorphin-1 post-treatment group (EM50 group), endomorphin-1+wortmannin (a PI3K/Akt signaling pathway inhibitor) treatment group (EM50+Wort group), and wortmannin treatment group (Wort group). Rat models of myocardial IR injury were established by ligation of the left anterior descending coronary artery for 30 min followed by reperfusion for 120 min. The heart rate and mean arterial pressure were monitored during the experiment. Plasma levels of LDH, CK-MB, cTnI, IL-6, TNF-α, SOD and MDA were measured after reperfusion. The mRNA expression of Bax and Bcl-2 was detected using RT-PCR, and the expression of apoptosis-related protein cleaved caspase-3, phosphorylated Akt protein and total Akt protein in myocardial tissue was detected using Western blotting. OBJECTIVE Myocardial IR injury significantly decreased heart rate and blood pressure of the rats in comparison with the sham operation (P < 0.05). Compared with those in the IR group, the rats in EM50 group showed significantly increased heart rate and blood pressure (P < 0.05) with decreased plasma LDH, CK-MB, cTnI, IL-6, TNF-α and MDA levels (P < 0.05), increased SOD activity (P < 0.05), increased expression of p-Akt protein and Bcl-2 mRNA (P < 0.05), and decreased expression of Bax mRNA and cleaved caspase-3 protein (P < 0.05). In EM50+Wort group, the heart rate and blood pressure were significantly lowered (P < 0.05), plasma LDH, CK-MB, cTnI, IL-6, TNF-α and MDA levels increased (P < 0.05), SOD activity decreased (P < 0.05), the expression of p-Akt protein and Bcl-2 mRNA was reduced (P < 0.05), and the expression of Bax mRNA and cleaved caspase-3 protein increased (P < 0.05) as compared with those in EM50 group. OBJECTIVE EM-1 postconditioning can regulate cardiac myocyte apoptosis and reduce myocardial IR injury in rats. The PI3K/Akt signaling pathway may play a role in mediating the myocardial protective effects of EM-1 postconditioning.

Abstract
Periprocedural myocardial injury and myocardial infarction (MI) are not infrequent complications of percutaneous coronary intervention (PCI) and are associated with greater short- and long-term mortality. There is an abundance of preclinical and observational data demonstrating that high levels of pre-, intra- and post-procedural inflammation are associated with a higher incidence of periprocedural myonecrosis as well as future ischaemic events, heart failure hospitalisations and cardiac-related mortality. Beyond inflammation associated with the underlying coronary pathology, PCI itself elicits an acute inflammatory response. PCI-induced inflammation is driven by a combination of direct endothelial damage, liberation of intra-plaque proinflammatory debris and reperfusion injury. Therefore, anti-inflammatory medications, such as colchicine, may provide a novel means of improving PCI outcomes in both the short- and long-term. This review summarises periprocedural MI epidemiology and pathophysiology, evaluates the prognostic value of pre-, intra- and post-procedural inflammation, dissects the mechanisms involved in the acute inflammatory response to PCI and discusses the potential for periprocedural anti-inflammatory treatment.

Neutrophil-to-Lymphocyte Ratio at Emergency Room Predicts Mechanical Complications of ST-segment Elevation Myocardial Infarction. J Korean Med Sci 2021; 36:e131. [PMID: 34002551 PMCID: PMC8129614 DOI: 10.3346/jkms.2021.36.e131] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2020] [Accepted: 03/30/2021] [Indexed: 11/20/2022] Open
Abstract
BACKGROUND The neutrophil-to-lymphocyte ratio (NLR) has been proven to be a reliable inflammatory marker. A recent study reported that elevated NLR is associated with adverse cardiovascular events in patients with ST-segment elevation myocardial infarction (STEMI). We investigated whether NLR at emergency room (ER) is associated with mechanical complications of STEMI undergoing primary percutaneous coronary intervention (PCI). METHODS A total of 744 patients with STEMI who underwent successful primary PCI from 2009 to 2018 were enrolled in this study. Total and differential leukocyte counts were measured at ER. The NLR was calculated as the ratio of neutrophil count to lymphocyte count. Patients were divided into tertiles according to NLR. Mechanical complications of STEMI were defined by STEMI combined with sudden cardiac arrest, stent thrombosis, pericardial effusion, post myocardial infarction (MI) pericarditis, and post MI ventricular septal rupture, free-wall rupture, left ventricular thrombus, and acute mitral regurgitation during hospitalization. RESULTS Patients in the high NLR group (> 4.90) had higher risk of mechanical complications of STEMI (P = 0.001) compared with those in the low and intermediate groups (13% vs. 13% vs. 23%). On multivariable analysis, NLR remained an independent predictor for mechanical complications of STEMI (RR = 1.947, 95% CI = 1.136-3.339, P = 0.015) along with symptom-to balloon time (P = 0.002) and left ventricular dysfunction (P < 0.001). CONCLUSION NLR at ER is an independent predictor of mechanical complications of STEMI undergoing primary PCI. STEMI patients with high NLR are at increased risk for complications during hospitalization, therefore, needs more intensive treatment after PCI.

Abstract
Objective This study aimed to investigate the predictive value of inflammatory cells in peripheral blood on the prognosis of patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI). Methods Patients (n=1558) were consecutively enrolled and the median follow-up was 1142 days. Patients were divided into the major adverse cardiac events (MACE) 1 group (n=63) (all-cause mortality [n=58] and rehospitalization for severe heart failure [n=5], no MACE1 group (n=1495), MACE2 group (n=38) (cardiac mortality [n=33] and rehospitalization for severe heart failure [n=5]), and no MACE2 group (n=1520). The neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), and platelet-to-lymphocyte ratio (PLR) were analyzed. Results The NLR, MLR, and PLR were higher in the MACE groups than in the no MACE groups. Different subsets of inflammatory cells had similar diagnostic values for MACE. Kaplan–Meier curves showed that the survival time gradually decreased with an increase in the degree of risk as determined by the NLR, MLR, and PLR. The risk of MACE was highest in the extremely high-risk group. Conclusion Peripheral blood inflammatory cell subsets can predict MACE in patients with ACS undergoing PCI. These cell subsets could be important laboratory markers for the prognosis and clinical treatment of these patients.

Cardiovasc Hematol Disord Drug Targets 2021; 20:191-197.

Abstract
OBJECTIVES In this study, we aimed to assess the value of admission time CBC parameters in predicting post-primary PCI corrected TIMI frame count. BACKGROUND Recent years have witnessed a large series of studies evaluating different laboratory variables to predict no-reflow phenomenon following primary PCI (PPCI) in patients with STEMI. However, a general agreement about the most reliable predictor of the no-reflow phenomenon is challenging and also intriguing. METHODS The current study concluded 208 consecutive patients who underwent primary PCI for ST-Elevation Myocardial Infarction (STEMI) from January 2014 to February 2016. Blood samples were obtained after taking ECG. Complete blood samples were collected and analyzed within 5 minutes from sampling. Post-PCI corrected Thrombolysis in Myocardial Infarction (TIMI) frame count was determined by one interventional cardiologist blinded to patients' clinical data. The correlation between admission time blood parameters and post-primary PCI corrected TIMI frame count in patients with STEMI were assessed. RESULTS Corrected TIMI frame count was positively correlated with WBC count (R: 0.18, P-value: <0.01), neutrophil count (R: 0.34, P-value: <0.01), and platelet count (R: 0.23, P-value: <0.01) and negatively correlated with lymphocyte count (R: -0.2, P-value: <0.01). Multiple linear regression results demonstrated that corrected TIMI frame count was positively correlated with neutrophil count (P < 0·001) and platelet count (P < 0·001) and negatively correlated with lymphocyte count (p=0.004). CONCLUSION High counts of WBC, neutrophil, and platelet and low count of lymphocyte may be predictors of no-reflow in STEMI patients undergoing PPCI. The clinical significance of such predictive parameters becomes clear as we consider the treatment approach in STEMI patients. Appropriate risk stratification leads to better treatment planning and allocation of resources.

Abstract
The values of hematological and coagulation biomarkers were evaluated as predictors of in hospital mortality and complications, in patients with acute coronary syndromes (ACS). This retrospective observational study enrolled 936 ACS subjects admitted to the Clinical Emergency Hospital of Oradea, Romania, between January-December 2019. Hematological and coagulation parameters were obtained at admission. During hospitalization, the following adverse events were recorded: death, ventricular rhythm disturbances, atrial fibrillation, heart failure, re-infarction, and stroke. Accuracy of hematological and coagulation parameters as predictors of adverse outcome were also evaluated. The diagnosis was unstable angina in 442 patients (47.22%), non-ST-elevation myocardial infarction (NSTEMI) in 113 patients (12.1%) and ST-elevation myocardial infarction (STEMI) in 381 patients (40.70%); 87 patients (9.29%) died during hospitalization and 193 (20.7%) developed complications. Predictors for in hospital mortality were as follows: red cell distribution width (RDW) (AUC 0.691, p < 0.0001), white blood cells (WBC) (AUC 0.684, p < 0.0001), neutrophils (NEU) (AUC 0.684, p < 0.0001), and prothrombin time (PT) (AUC 0.765, p < 0.0001). WBC (AUC 0.659, p < 0.0001), NEU (AUC 0.664, p < 0.0001), RDW (AUC 0.669, p < 0.0001), and PT (AUC 0.669, 95% CI 0.622-0.714, p < 0.0001) also had accuracy for complications prediction. RDW had a good ability to predict heart failure in NSTEMI patients (AUC 0.832, p < 0.0001). An acceptable ability to predict ventricular rhythm disturbances occurrence had WBC (AUC 0.758, p < 0.0001) and NEU (AUC 0.772, p < 0.0001). Hematological and coagulation parameters can help in risk stratification of ACS patients. RDW, WBC, NEU, and PT were able to predict mortality and in-hospital complications in ACS patients. RDW has a good accuracy in predicting complications and heart failure in NSTEMI patients. WBC and NEU are good predictors for ventricular rhythm disturbances.

Abstract
AIMS Lymphopenia after ST-segment elevation myocardial infarction (STEMI) correlates with deleterious cardiac consequences and worse prognosis. An in-depth examination of genes implicated in lymphocyte proliferation, activation and regulation and their association with short- and long-term cardiac structure and function is therefore of great interest. METHODS Peripheral blood mononuclear cells were isolated from 10 control subjects and 64 patients with a first STEMI treated with primary percutaneous coronary intervention and submitted to cardiac magnetic resonance after 1 week and 6 months. mRNA expression of genes implicated in lymphocyte activation (CD25 and CD69) and regulation [programmed death (PD)-1 and cytotoxic T-lymphocyte antigen (CTLA)-4] were determined by qRT-PCR. RESULTS In comparison to controls, STEMI patients showed heightened mRNA expression of CD25 and lower PD-1 and CTLA-4 96 h after coronary reperfusion. Patients with extensive infarctions (>30% of left ventricular mass) at 1 week displayed a notable reduction in CD25, CD69, PD-1, and CTLA-4 expression (p < 0.05). However, CD25 was the only predictor of 1-week extensive infarct size in multivariate logistic regression analysis (odds ratio 0.019; 95% confidence interval [0.001-0.505]; p = 0.018). Regarding long-term ventricular function, mRNA expression of CD25 under the mean value was associated with worse ventricular function and more adverse remodelling. CONCLUSIONS Following STEMI, heightened expression of genes expressed in regulatory T cells (CD25 and CD69) and immune checkpoints (PD-1 and CTLA-4) correlates with a better short- and long-term cardiac structure and function. Advancing understanding of the pathophysiology of lymphopenia and evaluating novel immunomodulatory therapies will help translate these results into future clinical trials.

Abstract
BACKGROUND The platelet to lymphocyte ratio (PLR) is a novel biomarker to predict the prognosis of acute myocardial infarction (AMI) patients. AIM The study aimed to evaluate the in-hospital outcomes of elderly patients with AMI and assessed the prognostic value of PLR on in-hospital adverse events. METHODS A total of 1,001 patients were divided into an older group (n = 560) and a younger group (n = 441) based on age ≥ 60 years and successfully underwent primary percutaneous coronary intervention (PCI) within 12 h after presentation. Total white blood cells (WBCs), neutrophils, lymphocytes, and platelets counts were measured at admission. RESULTS The incidence of heart rupture, acute heart failure, total adverse events, and death resulting from all events were significantly higher in patients ≥ 60 years than in younger patients, whereas the incidence of postoperative angina and reinfarction were similar between groups. Regarding blood counts, total white blood cells, neutrophils, lymphocytes, and platelets were lower in the older group than in the younger group. The platelet-to-lymphocyte ratio (PLR) was significantly higher in the older group. In receiver operating characteristic curve analysis, high PLR > 147 predicted adverse events (specificity 72% and sensitivity 63%). In multiple logistic regression analysis, age, hypertension, and PLR were identified as independent predictors of adverse events. CONCLUSIONS The in-hospital outcomes of elderly patients with acute myocardial infarction were poor. PLR was an independent risk factor for in-hospital adverse events, which suggested that strong inflammation and prothrombotic status may contribute to the poor prognoses of elderly patients.

Abstract
BACKGROUND Inflammation is involved in the pathogenesis and progression of coronary artery diseases (CADs), including acute coronary syndrome. The neutrophil-to-lymphocyte ratio (NLR) has been identified as a novel marker of the pro-inflammatory state. We aimed to evaluate the predictive efficacy of the NLR for the prognosis of patients with new-onset ACS. METHODS We retrospectively included consecutive patients with new-onset ACS treated with emergency coronary angiography. NLR was measured at baseline and analyzed by tertiles. The severity of coronary lesions was evaluated by the Gensini score. Correlations of NLR with the severity of CAD and the incidence of major adverse cardiovascular diseases (MACEs) during follow-up were determined. RESULTS Overall, 737 patients were included. The NLR was positively correlated with the severity of coronary lesions as assessed by Gensini score (P < 0.05). During the follow-up period (mean, 43.49 ± 23.97 months), 65 MACEs occurred. No significant association was detected between baseline NLR and the risk of MACEs during follow-up by either Kaplan-Meier or Cox regression analysis. Multivariable logistic regression analysis showed that a higher NLR was independently associated with coronary lesion severity as measured by the Gensini score (1st tertile vs. 3rd tertile hazard ratio [HR]: 0.527, P < 0.001, and 2nd tertile vs. 3rd tertile HR: 0.474, P = 0.025). CONCLUSIONS The NLR may be associated with coronary disease severity at baseline but is not associated with adverse outcomes in patients with new-onset ACS. ETHICS APPROVAL NUMBER 2019XE0208.

Abstract
INTRODUCTION Chronic inflammation plays a considerable role in atherosclerosis and may occur simultaneously in different arteries. This condition is referred to as multisite arterial disease (MSAD). We aimed to investigate the association between inflammatory markers and MSAD. METHODS In this cross-sectional study we included 526 patients with peripheral artery disease (PAD). Patients with PAD were evaluated by conventional or computed tomography angiography for the presence of coronary artery disease (CAD) and those with at least 30% stenosis were included in the study. Patients were divided into two groups: either MSAD+(PAD and CAD), Group 1) or MSAD- (only PAD without CAD, Group 2). Inflammatory markers were compared between the two groups. RESULTS Among all patients, 293 had MSAD while 233 had only PAD. The MSAD+group had higher neutrophil-to-lymphocyte ratio (NLR) and platelet-to-neutrophil ratio (PLR) (5.08±0.19, 4.67±0.51, and 207.1±6.23, 169.3±10.8, respectively, p<0.001). In multivariate analysis, HT [odds ratio (OR): 2.40 (1.61-3.59)); p<0.002], male gender [OR: 2.03 (1.29-3.17); p=0.002], DM [OR:1.56 (1.03-2.36); P=0.035], NLR [OR: 1,08 (1.02-1.16); p=0.021, and PLR [OR:1.05 (1.03-1.08); p<0.001] were found to be associated with MSAD. CONCLUSION NLR and PLR are correlated with MSAD and may indicate the extent of atherosclerosis.

Abstract
Background No-reflow occurs in 3–4% of all percutaneous coronary interventions (PCIs) and has a strong negative impact on clinical outcomes of acute coronary syndrome (ACS). Therefore, the discovery of a biomarker that can early predict the occurrence of no-reflow has great clinical significance. Multiple factors including platelet activation are relevant to no-reflow. Calprotectin is found to be a biomarker of plaque instability and is identified to be a novel diagnostic and prognostic biomarker of cardiovascular diseases. The association of plasma calprotectin with platelet activation and no-reflow phenomenon in ACS is not clear. Methods In this prospective study performed at Yantai Yuhuangding Hospital from 2017 to 2018, a total of 176 Chinese patients with ACS who had undergone PCIs were recruited consecutively, aged from 30 to 88 years. Angiographic no-reflow was defined as thrombolysis in myocardial infarction grade less than 3. Blood samples were collected immediately at admission for the detection of plasma calprotectin and platelet–monocyte aggregates formation. Statistical analysis was performed for the variable’s comparisons between groups and the prediction value of plasma calprotectin for no-reflow. Results The mean age of the 176 included ACS patients were 64(±11) years and acute ST-segment elevation myocardial infarction (STEMI) was present in 41.5% of patients. Twenty-two patients had no-reflow during the PCI procedures and the prevalence was 12.5%. Patients with higher plasma calprotectin had a higher level of platelet–monocyte aggregates (PMA) and a higher prevalence of no-reflow (p < 0.001). The multivariate regression showed that plasma calprotectin and admission hs-cTnI were independently associated with PMA, while plasma calprotectin and serum LDL-c were independent predictors of no-reflow (p < 0.001 and p = 0.017). AUC of calprotectin for predicting no-reflow were 0.898. The cut-off value of plasma calprotectin for no-reflow was 4748.77 ng/mL with a sensitivity of 0.95 and a specificity of 0.77. Conclusion Plasma calprotectin was associated with platelet activation and may act as an early predictive biomarker of no-reflow in patients with acute coronary syndrome.

Abstract
No-reflow phenomenon (NRP) is an important problem in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (pPCI). Endocan is synthesized and secreted by activated vascular endothelium, and it has been shown to be related to endothelial dysfunction and inflammation. We aimed to evaluate the relationship between endocan levels and NRP. Consecutive patients (n = 137) with STEMI who had undergone coronary angiography and pPCI were enrolled into the study. The clinical characteristics of the patients were obtained and endocan levels were measured. Endocan levels were significantly higher in the NRP (+) group compared with the NRP (-) group (P < .001). In multivariate analysis, endocan (P < .001, OR = 2.39, 95% CI = 1.37-4.15) was found to be an independent predictor of NRP. An endocan value of >2.7 ng/mL has 89.6% sensitivity and 74.2% specificity for the prediction of the NRP (area under the curve: 0.832, P < .001). The present study demonstrated that the endocan level is an independent predictor of the NRP in patients with STEMI who underwent pPCI. Endocan levels may be helpful in detecting patients with a higher risk of insufficient myocardial perfusion and worse clinical outcome.

Abstract
OBJECTIVE Inflammation-related markers provide diagnostic and prognostic information for coronary artery disease and acute coronary syndrome. We aimed to compare neutrophil count and neutrophil/lymphocyte ratio (NLR) in acute coronary syndrome patients with coronary collateral development in our study. METHODS A total of 426 patients (102 unstable angina pectoris (USAP), 223 non-ST-elevation myocardial infarction (non-STEMI), 103 ST-elevation myocardial infarction (STEMI) were compared regarding hemoglobin, platelet, lymphocyte, neutrophil count, and NLR. RESULTS Neutrophil count and NLR were significantly lower in USAP patients and higher in STEMI patients; 5.14± 1.79 vs. 7.21± 3.05 vs. 9.93±4.67 and 2.92±2.39 vs. 5.19±4.80 vs. 7.93±6.38, p <0.001. Other parameters, i.e., hemoglobin, platelet, and lymphocyte count, were not significantly different between the groups. CONCLUSIONS In our study, it was concluded that there may be a statistically significant difference in the number of neutrophil counts and NLR among the types of acute coronary syndromes with coronary collateral development.

Abstract
BACKGROUND ST-segment elevation myocardial infarction (STEMI) is the most life-threatening condition of acute coronary syndrome that carries a poor prognosis of in-hospital mortality. Multiple scoring systems have been developed to predict in-hospital mortality and other cardiovascular events. Neutrophil-to-lymphocyte ratio (NLR) is hardly used as a predictor of in-hospital mortality. This study was aimed to determine the predictive value of NLR concerning in-hospital mortality in STEMI patients.
METHODS Literature search and pooled analysis related to studies on MEDLINE/PubMed, EBSCO, Science Direct, Cochrane, and ProQuest were retrieved. Inclusion criteria were met if they were cohort studies, the subjects were STEMI patient, contained pretreatment NLR cut-off, and considered in-hospital mortality, which is defined as cardiac or all-cause mortality. Quality assessment was conducted using Newcastle-Ottawa scale. Review Manager version 5.3 (The Nordic Cochrane Centre, Copenhagen) was used for meta-analysis.
RESULTS We found 12 studies with a total of 7,251 STEMI subjects with median NLR cut-off value of 5.6. Elevated NLR on admission carries a high risk of in-hospital mortality (odds ratio [OR] = 3.00, 95% confidence interval [CI] = 2.46–3.67). A slightly higher risk of all-cause mortality (OR = 2.74, 95% CI = 1.99–3.77) was observed compared with cardiac-related mortality (OR = 3.20, 95% CI = 2.47–4.14). No significant heterogeneity was observed between these studies (p = 0.46, I2 = 0%).
CONCLUSIONS Elevated NLR predicts a higher in-hospital mortality rate of STEMI patients.

Abstract
OBJECTIVE To evaluate the predictive value of the neutrophil-to-lymphocyte ratio (NLR), mean platelet volume (MPV), and platelet distribution width (PDW) for the no-reflow phenomenon in patients with ST-segment elevation myocardial infarction. Methods: Patients who underwent primary percutaneous coronary intervention from January 2017 to April 2019 were consecutively enrolled in this study and were split into the control and no-reflow groups. Logistic regression analysis was used to determine the independent predictors. Receiver operating characteristic curves were carried out to evaluate the predictive value. Results: A total of 455 patients were included and the incidence of the no-reflow was 19.6%. After the adjustment of confounding factors, logistic regression analyses showed that the NLR (odds ratio [OR] per unit increase: 1.107, 95% confidence interval [CI]: 1.044-1.172, p = .001), MPV (OR: 1.398, 95% CI: 1.010-1.937, p = .044), and PDW (OR: 1.392, 95% CI: 1.012-1.914, p = .042) were all independent predictors. In the prediction of the no-reflow, the NLR had the largest area under the curve of 0.650 (95% CI: 0.593-0.708) with 90% sensitivity and 36% specificity. The area under the curve of the combination of NLR + MPV was 0.676 and that of NLR + PDW was 0.654. Conclusions: The NLR, MPV and PDW are all associated with the no-reflow. However, there is no significant difference in the predictive value of these indicators. The combinations of NLR and platelet-associated parameters also do not show a better predictive value than NLR alone.

Abstract
BACKGROUND AND AIM Neutrophil-lymphocyte ratio (NLR) and lymphocyte-monocyte ratio (LMR) are associated with clinical outcomes in malignancy, cardiovascular disease and stroke. Here we investigate their association with outcome after acute ischaemic stroke treated by mechanical thrombectomy (MT). METHODS Patients were selected using audit data for MT for acute anterior circulation ischaemic stroke at a UK centre from May 2016-July 2017. Clinical and laboratory data including neutrophil, lymphocyte and monocyte count tested before and 24 h after MT were collected. Poor functional outcome was defined as modified Rankin Scale (mRS) of 3-6 at 3 months. Multivariable logistic regression analyses were performed to explore the relationship of NLR and LMR with functional outcome. RESULTS One hundred twenty-one patients (mean age 66.4 ± 16.7, 52% female) were included. Higher NLR (adjusted OR 0.022, 95% CI, 0.009-0.34, p = 0.001) and lower LMR (adjusted OR - 0.093, 95% CI (- 0.175)-(- 0.012), p = 0.025) at 24-h post-MT were significantly associated with poorer functional outcome when controlling for age, baseline NIHSS score, infarct size, presence of good collateral supply, recanalisation and symptomatic intracranial haemorrhage on multivariate logistic regression. Admission NLR or LMR were not significant predictors of mRS at 3 months. The optimal cut-off values of NLR and LMR at 24-h post-MT that best discriminated poor outcome were 5.5 (80% sensitivity and 60% specificity) and 2.0 (80% sensitivity and 50% specificity), respectively on receiver operating characteristic curve analysis. CONCLUSION NLR and LMR tested at 24 h after ictus or intervention may predict 3-month functional outcome.

Abstract
C-reactive protein (CRP) and high-sensitivity CRP (hsCRP), along with a series of hematological indices, platelet to lymphocyte ratio (PLR), neutrophil to lymphocyte ratio (NLR), mean platelet volume (MPV), platelet distribution width (PDW), and red blood cell distribution width (RDW), are regarded to be related to the incidence of no-reflow or slow flow. Clinical studies were retrieved from the electronic databases of PubMed, EMBASE, Google Scholar, Clinical Trials, and science direct from their inception to August 24, 2019. A total of 21 studies involving 7403 patients were included in the meta-analysis. Pooled analysis results revealed patients with higher hsCRP (odds ratio [OR] = 1.03, 95% confidence interval [CI], 1.01-1.05, P = .006), hsCRP (OR = 1.04, 95% CI: 1.0-1.08, P = .012), NLR (OR = 1.23, 95% CI: 1.11-1.37, P < .0001), PLR (OR = 1.13, 95% CI: 1.07-1.20, P < .0001), and MPV (OR = 2.13, 95% CI: 1.57-2.90, P < .0001) all exhibited significantly higher no-reflow incidence, but there was no significant association between no-reflow risk and RDW or PDW. Patients with higher CRP/hsCRP also performed higher rate of slow flow (OR = 1.06, 95% CI: 1.01-1.11, P = .018). Preangiographic CRP/hsCRP could independently predict no-reflow and slow flow. Moreover, some hematological indices are associated with no-flow.

Abstract
Amplified innate leukocytes (neutrophils and monocytes/macrophages) are associated with advanced ischemic and non-ischemic heart failure (HF). Intensified neutrophilic leukocytosis (neutrophilia) and sustained activation of neutrophils is the predominant factor that determines over activated inflammation in acute HF and the outcome of long-term chronic HF. After heart attack, the first wave of innate responsive and short-lived neutrophils is essential for the initiation of inflammation, resolution of inflammation, and cardiac repair, however uncontrolled and long-term activation of neutrophils leads to collateral damage of myocardium. In the presented review, we highlighted the interactive and integrative role of neutrophil phenotypes in cellular and molecular events of ischemic HF. In addition, we discussed the current, nonimmune, immune, and novel paradigms of neutrophils in HF associated with differential factors with a specific interest in non-resolving inflammation and resolution physiology.

White Blood Cell Count Improves Prediction of Delayed Cerebral Ischemia Following Aneurysmal Subarachnoid Hemorrhage. Neurosurgery 2019.

Abstract
BACKGROUND Immune dysregulation has long been implicated in the development of delayed cerebral ischemia (DCI) following aneurysmal subarachnoid hemorrhage (aSAH). OBJECTIVE To determine the relationship of inflammatory cell biomarkers with DCI. METHODS We evaluated 849 aSAH patients who were enrolled into a prospective observational cohort study and had a white blood cell (WBC) differential obtained within 72 h of bleed onset. RESULTS WBC count > 12.1 × 109/L (odds ratio 4.6; 95% confidence interval [CI]: 1.9-11, P < 0.001) was the strongest Complete Blood Count (CBC) predictor of DCI after controlling for clinical grade (P < .001), thickness of SAH blood on admission computed tomography (P = .002), and clipping aneurysm repair (P < .001). A significant interaction between clinical grade and WBC count (odds ratio 0.8, 95% CI: 0.6-1.0, P = .02) revealed that good-grade patients with elevated WBC counts (49%: 273/558) had increased odds for DCI indistinguishable from poor-grade patients. Multivariable Cox regression also showed that elevated WBC counts in good-grade patients increased the hazard for DCI to that of poor-grade patients (hazard ratio 2.1, 95% CI 1.3-3.2, P < .001). Receiver operating characteristic curve analysis of good-grade patients revealed that WBC count (area under the curve [AUC]: 0.63) is a stronger DCI predictor than the modified Fisher score (AUC: 0.57) and significantly improves multivariable DCI prediction models (Z = 2.0, P = .02, AUC: 0.73; PPV: 34%; NPV: 92%). CONCLUSION Good-grade patients with early elevations in WBC count have a similar risk and hazard for DCI as poor-grade patients. Good-grade patients without elevated WBC may be candidates to be safely downgraded from the intensive care unit, leading to cost savings for both patient families and hospitals.

[PMID: 31835088 DOI: 10.1016/j.intimp.2019.106063] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2019] [Revised: 11/15/2019] [Accepted: 11/15/2019] [Indexed: 02/07/2023]
Abstract
BACKGROUND Chronic kidney disease (CKD) patients have a high incidence of cardiovascular disease (CVD) events, which is related to the inflammatory status of this population. Platelet-to-lymphocyte ratio (PLR) is a relatively new indicator of inflammation. The aim of this study was to investigate the relationship between PLR and the CVD events in continuous ambulatory peritoneal dialysis (CAPD) patients. METHODS A total of 70 stable CAPD patients were included in this study from February 2014 to March 2017, and complete demographic characteristics and clinical laboratory baseline data were collected at enrollment. The primary endpoint was defined as the experienced of CVD events during the follow-up period. Binary logistic regression was used to assess the association between PLR and CVD events in CAPD patients. RESULTS During a median follow-up period of 22 months, 28 (40%) CAPD patients experienced CVD events. Patients in the CVD event group had a high level of platelets (P < 0.01), C-reactive protein (P < 0.01), PLR (P < 0.01) and neutrophil-to-lymphocyte ratio (NLR) (P < 0.01). However, lymphocyte counts (P < 0.01) were significantly lower than patients without CVD events. Following adjusted binary regression analysis revealed no relationship between high NLR and CVD events (OR, 1.21; 95% CI, 0.52-2.85; p = 0.44). However, the correlation between high PLR and CVD events was significant (OR, 1.05; 95% CI, 1.02-1.08; p < 0.01). High PLR was confirmed as an independent predictor of CVD events. CONCLUSION Our results demonstrated that PLR was independently associated with CVD events. High PLR can be used to predict the risk of CVD events in CAPD patients. PLR was easy to obtain and can be considered as a routine test to serve the clinic.
