Abstract
Ischemic heart disease (IHD) can trigger responses from the innate immune system, provoke aseptic inflammatory processes, and result in the recruitment and accumulation of neutrophils. Excessive recruitment of neutrophils is a potential driver of persistent cardiac inflammation. Once recruited, neutrophils are capable of secreting a plethora of inflammatory and chemotactic agents that intensify the inflammatory cascade. Additionally, neutrophils may obstruct microvasculature within the inflamed region, further augmenting myocardial injury in the context of IHD. Immune-related molecules mediate the recruitment process of neutrophils, such as immune receptors and ligands, immune active molecules, and immunocytes. Non-immune-related molecular pathways represented by pro-resolving lipid mediators are also involved in the regulation of NR. Finally, we discuss novel regulating strategies, including targeted intervention, agents, and phytochemical strategies. This review describes in as much detail as possible the upstream molecular mechanism and external intervention strategies for regulating NR, which represents a promising therapeutic avenue for IHD.

Cheng W, Li T, Wang X, Xu T, Zhang Y, Chen J, Wei Z. The neutrophil-to-apolipoprotein A1 ratio is associated with adverse outcomes in patients with acute decompensated heart failure at different glucose metabolic states: a retrospective cohort study. Lipids Health Dis 2024; 23:118. [PMID: 38649986 PMCID: PMC11034163 DOI: 10.1186/s12944-024-02104-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2024] [Accepted: 04/06/2024] [Indexed: 04/25/2024] Open
Abstract
BACKGROUND The present study was performed to assess the association between the neutrophil-to-apolipoprotein A1 ratio (NAR) and outcomes in patients with acute decompensated heart failure (ADHF) at different glucose metabolism states. METHODS We recruited 1233 patients with ADHF who were admitted to Nanjing Drum Tower Hospital, Affiliated Hospital of Medical School, Nanjing University from December 2014 to October 2019. The endpoints were defined as composites of cardiovascular death, nonfatal myocardial infarction, nonfatal ischemic stroke and exacerbation of chronic heart failure. The restricted cubic spline was used to determine the best cutoff of NAR, and patients were divided into low and high NAR groups. Kaplan-Meier plots and multivariable Cox proportional hazard models were used to investigate the association between NAR and the risk of adverse outcomes. RESULTS During the five-year follow-up period, the composite outcome occurred in 692 participants (56.1%). After adjusting for potential confounding factors, a higher NAR was associated with a higher incidence of composite outcomes in the total cohort (Model 1: HR = 1.42, 95% CI = 1.22-1.65, P<0.001; Model 2: HR = 1.29, 95% CI = 1.10-1.51, P = 0.002; Model 3: HR = 1.20, 95% CI = 1.01-1.42, P = 0.036). At different glucose metabolic states, a high NAR was associated with a high risk of composite outcomes in patients with diabetes mellitus (DM) (Model 1: HR = 1.54, 95% CI = 1.25-1.90, P<0.001; Model 2: HR = 1.40, 95% CI = 1.13-1.74, P = 0.002; Model 3: HR = 1.31, 95% CI = 1.04-1.66, P = 0.022), and the above association was not found in patients with prediabetes mellitus (Pre-DM) or normal glucose regulation (NGR) (both P>0.05). CONCLUSIONS The NAR has predictive value for adverse outcomes of ADHF with DM, which implies that the NAR could be a potential indicator for the management of ADHF.

Wang X, Zhang Y, Wang Y, Liu J, Xu X, Liu J, Chen M, Shi L. The neutrophil percentage-to-albumin ratio is associated with all-cause mortality in patients with chronic heart failure. BMC Cardiovasc Disord 2023; 23:568. [PMID: 37980510 PMCID: PMC10657562 DOI: 10.1186/s12872-023-03472-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Accepted: 08/24/2023] [Indexed: 11/20/2023] Open
Abstract
BACKGROUND In this study, we evaluated the predictive utility of neutrophil percentage-to-albumin ratio (NPAR) for all-cause mortality in patients with chronic heart failure (CHF). METHODS Patients diagnosed as CHF enrolled in this retrospective cohort study were from Beijing Chaoyang Hospital, capital medical university. Admission NPAR was calculated as neutrophil percentage divided by serum albumin. The endpoints of this study were defined as 90-day, 1-year and 2-year all-cause mortality. Multivariable Cox proportional hazard regression model was performed to confirm the association between NPAR and all-cause mortality. Receiver operating characteristics (ROC) curves were used to evaluate the ability for NPAR to predict all-cause mortality. RESULTS The 90-day (P = 0.009), 1-year (P < 0.001) and 2-year (P < 0.001) all-cause mortality in 622 patients with CHF were increased as admission NPAR increased. Multivariable Cox regression analysis found the higher NPAR value was still independently associated with increased risk of 90-day (Group III versus Group I: HR, 95% CI: 2.21, 1.01-4.86, P trend = 0.038), 1-year (Group III versus Group I: HR, 95% CI:2.13, 1.30-3.49, P trend = 0.003), and 2-year all-cause mortality (Group III versus Group I: HR, 95% CI:2.06, 1.37-3.09, P trend = 0.001), after adjustments for several confounders. ROC curves revealed that NPAR had a better ability to predict all-cause mortality in patients with CHF, than either albumin or the neutrophil percentage alone. CONCLUSIONS NPAR was independently correlated with 90-day, 1-year, and 2-year all-cause mortality in patients with CHF.

Abstract
OBJECTIVE To investigate the association between cardiovascular diseases (CVDs) and haematologic factors in a cohort of Iranian adults. METHOD For a total population of 9,704 aged 35 to 65, a prospective study was designed. Haematologic factors and demographic characteristics (such as gender, age, and smoking status) were completed for all participants. The association between haematologic factors and CVDs was assessed through logistic regression (LR) analysis, decision tree (DT), and bootstrap forest (BF). RESULTS Almost all of the included factors were significantly associated with CVD (p<.001). Among the included factors, were: age, white blood cell (WBC), and platelet distribution width (PDW) had the strongest correlation with the development of CVD. For unit OR interpretation, WBC has been represented as the most remarkable risk factor for CVD (OR: 1.22 (CI 95% (1.18, 1.27))). Also, age is associated with an increase in the odds of CVD + occurrence (OR: 1.12 (CI 95% (1.11, 1.13))). Moreover, males are times more likely to develop CVD than females (OR: 1.39 (CI 95% (1.22, 1.58))). In DT model, age is the best classifier factor in CVD development, followed by WBC and PDW. Furthermore, based on the BF algorithm, the most crucial factors correlated with CVD are age, WBC, PDW, sex, and smoking status. CONCLUSION The obtained result from LR, DT, and BF models confirmed that age, WBC, and PDW are the most crucial factors for the development of CVD.

Abstract
Owing to the augmented perception of heart failure (HF) pathophysiology, management of the affected patients has been improved dramatically; as with the identification of the inflammatory background of HF, new avenues of HF prognosis research have been opened up. In this regard, relative values of hematologic indices were demonstrated by a growing body of evidence to successfully predict HF outcomes. Cost-effectiveness, accessibility, and easy obtainability of these relative values make them a precious option for the determination of HF prognosis; particularly in low-income developing countries. In this short review, we aimed to present the current literature on the predictability of these hematologic parameters for HF outcomes.

The Difference of Cholesterol, Platelet and Cortisol Levels in Patients Diagnosed with Chronic Heart Failure with Reduced Ejection Fraction Groups According to Neutrophil Count. ACTA ACUST UNITED AC 2021; 57:medicina57060557. [PMID: 34205836 PMCID: PMC8228361 DOI: 10.3390/medicina57060557] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2021] [Revised: 05/26/2021] [Accepted: 05/27/2021] [Indexed: 12/12/2022]
Abstract
Background and Objectives: It is known that neutrophils are involved in the pro-inflammatory processes and thus, can have a great impact on the pathophysiology of heart failure (HF). Moreover, hypercholesterolemia heightens neutrophil production, thereby accelerating cardiovascular inflammation. However, there is a lack of information about the relation of low inflammation to the state of stress, hypercholesterolemia, and pro-thrombotic statement in patients with chronic HF. Therefore, we aimed to determine whether platelet, cholesterol and cortisol levels differ in a different inflammatory condition groups according to the neutrophil count in patients diagnosed with CHF with reduced ejection fraction (CHFrEF), and whether there is a correlation between those readings. Materials and Methods: The average of neutrophil count was 4.37 × 109 L; therefore, 180 patients were separated into two groups: one with relatively a higher inflammatory environment (neutrophil count ≥ 4.37 × 109 L (n = 97)) and one with a relatively lower inflammatory environment (neutrophil count < 4.38 × 109 L (n = 83)). We also determined the levels of lymphocytes, monocytes, platelet count (PLT), mean platelet volume (MPV), platelet aggregation, the levels of cortisol and cholesterol and the concentrations of C reactive protein (CRP) and fibrinogen. Results: We found that CRP, fibrinogen and cortisol concentrations were statistically significantly higher in the group with higher neutrophil counts. However, there were no differences among cholesterol concentration and other markers of platelet function between the groups. We also showed that PLT, leukocyte and monocyte counts were higher in the group with a higher neutrophil count, and the PLT correlated with other cell type count and CRP. In addition, the neutrophil count correlated with concentrations of fibrinogen, evening cortisol and CRP. Conclusions: Cortisol, fibrinogen and CRP levels, PLT and monocyte counts were higher in the CHFrEF patient group with higher neutrophil counts. The cholesterol levels and platelet function readings did not differ between the groups. The neutrophil count correlated with evening cortisol concentration.

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.

Abstract
BACKGROUND We assessed the utility of the systemic immune-inflammatory index (SII) in estimating the in-hospital and long-term prognosis of elderly patients with acute myocardial infarction (AMI) who received percutaneous coronary intervention (PCI). MATERIAL AND METHODS Our study evaluated 711 consecutive elderly patients (age 65-85 years) from January 2015 to December 2017. The correlation between clinical outcomes and SII was analyzed through the stepwise Cox regression analysis and the Kaplan-Meier approach. The clinical endpoints were all-cause mortality and major adverse cardiovascular and cerebrovascular events (MACCE) in-hospital and during 3-year follow-up. RESULTS The study enrolled 711 elderly patients with AMI (66.95% male, 71.99±0.19 years). Kaplan-Meier analysis showed a lower survival rate in patients with higher SII scores, which also predicted in-hospital and long-term (≤3 years) outcomes. In multivariate analyses, SII showed an independent predictive value for in-hospital mortality (hazard ratio (HR), 3.32; 95% confidence interval (CI), 1.55-7.10; p<0.01), in-hospital MACCE (HR, 1.43; 95%CI, 1.02-2.00; p=0.04), long-term mortality (HR, 1.95; 95%CI, 1.23-3.09; p<0.01), along with long-term MACCE (HR, 1.72; 95%CI, 1.23-2.40; p<0.01). Moreover, SII showed a weak but significant positive relationship with the Gensini score among patients developing non-ST-segment elevation myocardial infarction (r=0.18; p<0.01). CONCLUSIONS SII, a readily available laboratory marker, is a potential indicator to predict the clinical endpoints for elderly patients with AMI undergoing PCI.

Abstract
OBJECTIVES Neutrophil to lymphocyte ratio (NLR) might be associated with the mortality or major adverse cardiac events (MACEs) in acute coronary syndrome (ACS) patients. We performed a meta-analysis to evaluate the correlation between NLR and mortality/MACEs in ACS. METHODS We assessed clinical trials through Pubmed, EMBASE, the Cochrane Library and Web of science in investigating the association between NLR and mortality/MACEs in ACS patients up to August 15, 2017. The primary outcome was mortality or recurrent MACEs. RESULTS In total, 8 studies of 9406 patients were included in the systematic and meta-analysis. Our analysis indicated that elevated pretreatment NLR was a poor prognostic marker for patients with recent ACS in predicting medium to long-term mortality/MACEs (OR 1.26, 95%CI 1.13-1.41). And the analysis indicated that higher pretreatment NLR value was associated with higher in-hospital mortality in ACS patients (OR 6.39, 95%CI 1.49-27.38, p<0.001). The NLR value of 5.0 maybe a cut-off value for ACS risk. CONCLUSIONS In patients with a recent ACS, an elevated pretreatment NLR value is effective in predicting the risk of mortality/MACEs.

Abstract
BACKGROUND AND AIM The aim of this study was to examine the association between the admission neutrophil-to-lymphocyte ratio (N/L ratio) with coronary heart disease (CHD), separately from acute coronary syndrome (ACS) and stable angina (SA). A further aim was to investigate the clinical value of the N/L ratio in predicting in-hospital CHD events and the long-term prognosis of patients with CHD. PATIENTS AND METHODS In all, 942 patients were enrolled and classified into a CHD group (comprising an ACS group and an SA group) and a normal group. Laboratory data including regular blood test results were obtained at baseline. The relationship between the N/L ratio and CHD, ACS, Gensini score, and multivessel lesions was analyzed by logistic regression. Receiver operating characteristics (ROC) curve analysis was used to identify the value of the N/L ratio in the diagnosis of CHD, ACS, and the severity of CHD. We divided the patients into four groups according to the N/L ratio quartiles and compared the differences in major adverse cardiac events (MACEs) that occurred in hospital and in the 4.26 ± 0.57-year follow-up out of hospital. RESULTS Patients with an elevated N/L ratio had a significantly increased risk of CHD [odds ratio (OR) = 1.697, 95 % confidence interval (CI) = 1.483-1.942], and an elevated N/L ratio was closely related to a higher risk of ACS (OR = 1.652, 95 % CI = 1.434-1.902). The admission N/L ratio (0.664; 95 % CI = 1.942-1.616) showed a greater ROC area than the WBC and LDL-C values. Patients with a higher N/L ratio in both the SA group and the ACS group had a higher incidence of in-hospital and out-of-hospital MACEs, including long-term mortality and occurrence of new-onset heart failure or re-occurrence of heart failure. An elevated N/L ratio on admission was also found to be a significant indicator of 4.26-year MACEs. CONCLUSION The admission N/L ratio was significantly associated with CHD and may become a risk predictor in the prognosis of patients with CHD.

Abstract
Objective: We aimed to study the predictive value of the neutrophil-lymphocyte ratio (NLR) for left ventricular systolic dysfunction (LVSD) in patients with non ST-elevated acute coronary syndrome (NST-ACS). Methods: A total of 405 patients (mean age 62 years and 75% male) with NST-ACS were included in the study. The study population was divided into tertiles based on admission NLR values. The low, medium and high tertiles defined as NLR≤1.81 (n=135), 1.81<NLR≤3.2 (n=135) and NLR>3.2 (n=135), respectively. Results: The patients in the high NLR group were older (p<0.001), have higher rate of diabetes mellitus (p=0.028) and non-ST elevated myocardial infarction (NSTEMI) (p<0.001) and have lower left ventricular ejection fraction (LVEF) (p<0.001). Baseline WBC (p=0.02) and neutrophil (p<0.001) levels and NLR (p<0.001) were significantly higher, baseline hemoglobin (p=0.044), hematocrit (p=0.019) and lymphocyte (p<0.001) levels were significantly lower in the high NLR group. NLR was negatively correlated with LVEF in correlation analysis. An NLR >3.2 and age ≥70 were found to be an independent predictor of systolic dysfunction in multivariate analyses. Conclusion: An NLR >3.2 is a useful predictor for LVSD in patients with NST-ACS. The practice of using an NLR count on admission may be useful for identifying high-risk patients and their associated treatment methods.

Abstract
BACKGROUND According to the present evidences suggesting association between low testosterone level and prediction of reduced exercise capacity as well as poor clinical outcome in patients with heart failure, we sought to determine if testosterone therapy improves clinical and cardiovascular conditions as well as quality of life status in patients with stable chronic heart failure. METHODS A total of 50 male patients who suffered from congestive heart failure were recruited in a double-blind, placebo-controlled trial and randomized to receive an intramuscular (gluteal) long-acting androgen injection (1 mL of testosterone enanthate 250 mg/mL) once every four weeks for 12 weeks or receive intramuscular injections of saline (1 mL of 0.9% wt/vol NaCl) with the same protocol. RESULTS The changes in body weight, hemodynamic parameters, and left ventricular dimensional echocardiographic indices were all comparable between the two groups. Regarding changes in diastolic functional state and using Tei index, this parameter was significantly improved. Unlike the group received placebo, those who received testosterone had a significant increasing trend in 6-walk mean distance (6MWD) parameter within the study period (P = 0.019). The discrepancy in the trends of changes in 6MWD between study groups remained significant after adjusting baseline variables (mean square = 243.262, F index = 4.402, and P = 0.045). CONCLUSION Our study strengthens insights into the beneficial role of testosterone in improvement of functional capacity and quality of life in heart failure patients.

Abstract
The important role of the immune system and inflammation in the pathophysiology of heart failure (HF) is becoming increasingly appreciated. We have reviewed the prognostic significance of under-recognized aspects of the leukocyte differential in HF, including lymphocytes, monocytes, eosinophils and mast cells. Studies to date evaluating lymphocyte counts in both chronic and hospitalized HF patients have consistently shown worse prognosis associated with low lymphocyte counts, despite widely heterogeneous study designs. Limited data suggest elevations in monocyte-derived cytokines and serum monocyte count may be predictive of poor outcomes in HF. Further data are required to better define the relationship between eosinophils, mast cells and HF. Leukocyte differentials are widely available, simple, inexpensive and appear to have independent prognostic significance, beyond traditional risk factors. Enhanced sympathetic activation and increased circulating cytokine levels (particularly tumor necrosis factor) have been implicated in the variability of leukocyte subpopulations. To date, immune-modulators targeting these mediators have been largely unsuccessful in improving cardiovascular outcomes in HF. Given the potential role of the immunological axis in HF, there may be an unmet need for novel therapeutic agents that can safely and effectively ameliorate these leukocyte derangements and perhaps improve the unacceptably high event rate in this population. Variations in leukocyte differentials may identify a high-risk subset of patients that may benefit from tailored immune therapies.

Abstract
Objective. Studies have shown that inflammation plays an important role in pathogenesis of coronary artery disease. The present study was designed to evaluate the role of high WBC count before CABG in predicting the risk of ischemic events after CABG. Methods and Results. This prospective study was carried out on 380 patients who underwent CABG surgery. Ninety seven patients (25.5%) had recurrent ischemic event. Mean WBC count before CABG surgery in patients with recurrent ischemic event was 7267 mic/lit ± 1863, which was significantly higher than the others, with a mean WBC count of 6721 mic/lit ± 1734 (P = 0.011). Patients with a WBC count more than 6000 mic/lit were at the highest risk for recurrent ischemic event (OR = 2.11, 95% CI = 1.18–3.44, P = 0.009). After adjustment for age, sex, family history, smoking, hyperlipidemia, Logestic Euro score, post opretive enzyme release (CK.mb), arterial graft and BMI, the relationship between the group with WBC count higher than 6000 mic/lit and recurrent of ischemic event remained significant (OR = 2.25, 95% CI = 1.2 to 4, P = 0.005). Conclusions. High WBC count before CABG surgery is an independent risk factor for ischemic events one year after the surgery.

Abstract
Introduction: Admission white blood cell (WBC) count and thrombosis in myocardial infarction (TIMI) risk score have been associated with adverse outcomes after acute myocardial infarction (AMI). This study investigated the joint effect of WBC count and TIMI risk score on predicting in-hospital outcomes in patients with AMI. Materials and Methods: WBC count and TIMI risk score were measured at the time of hospital admission in 70 patients with AMI. Echocardiogram was done on prior to discharge by a cardiologist and ejection fraction (EF) was determined according to the Simpson formula. Patients were stratified into tertiles (low and high) based on WBC count and TIMI risk score. Results: Patients with a high WBC count had a 5.0-fold increase in-hospital congestive heart failure and 2.2 increases in mortality compared with those with a low WBC count. Patients with a high TIMI risk score had a 10-fold increase in congestive heart failure presentation and mortality compared with those with a low TIMI risk score. When a combination of different strata for each variable was analyzed, a stepwise increase in mortality was seen. There were a few number of patients with a high WBC count and low TIMI risk score or with a low WBC count and high TIMI risk score. These patients had an intermediate risk, whereas those with a high WBC count and TIMI risk score had the highest risk. Conclusion: These findings suggested that a simple combination of WBC count and TIMI risk score might provide further information for predicting outcomes in patients with AMI.

Abstract
Some studies have suggested that high levels of total white blood cell (WBC) count and C-reactive protein (CRP) may be considered as independent prognostic factors in patients with acute coronary syndromes (ACS) and/or after cardiac revascularisation by percutaneous coronary intervention or coronary artery bypass grafting surgery. Evidence on the role of neutrophils in cardiovascular disease is less compelling. Therefore, we conducted a systematic review of the literature with the aim of identifying all the available evidence to clarify the role of neutrophils (absolute or relative count, neutrophil/lymphocyte ratio) as a prognostic risk factor in patients with ACS and/or cardiac revascularisation. All published studies evaluating the role of neutrophils as a risk factor for clinical outcomes were assessed using the MEDLINE and EMBASE databases. Study selection, data extraction and validity assessment was performed independently by two reviewers. Twenty-one studies (17 of which had positive results) for a total of more than 34,000 patients were included. Ten of 13 studies in ACS patients found that neutrophils measured on-admission are related to mortality rate and/or to major adverse clinical events. A predictive value of neutrophils after cardiac revascularisation procedures was reported in seven out of eight studies. Most of the studies showed that neutrophils were independent predictors of cardiovascular outcomes when analysed concomitantly with other markers of inflammation (WBC, CRP). The findings of our systematic review highlight the potential application of this inexpensive and readily available inflammatory marker for risk stratification in patients with ACS and/or cardiac revascularisation.

Abstract
Macrophage inflammatory protein-2 (MIP-2) is a C-X-C chemokine that is important in recruiting neutrophils to inflammatory sites. Our previous reports demonstrated that lipopolysaccharide (LPS) or CpG-oligode-oxynucleotide (CpG-ODN) rapidly induce MIP-2 gene expression in the macrophage cell line, RAW 264.7. Here, we show that the DNA sequence of the MIP-2 promoter between -114 and +14 is sufficient for strong promoter activity in LPS- or CpG-ODN-stimulated RAW 264.7 cells. Importantly, comprehensive mutant analysis reveals that an Sp1 element in the promoter region between -114 and -94 is essential for synergistic MIP-2 promoter activation by NF-kappaB and c-Jun regardless of the presence of an AP-1 site. By combining deletion or site-specific mutant analysis with immunocomplex assays, we also confirmed that Sp1 mediates the recruitment of transcription factors NF- kappaB and c-Jun in LPS- or CpG-ODN-treated RAW 264.7 cells. Several lines of experimental evidence imply that the Sp1-binding element is an important determinant of MIP-2 promoter activity, and that NF-kappaB, c-Jun and Sp1 can functionally cooperate to elicit maximal activation of the promoter.
