Abstract
This study aimed to validate an inflammation-based risk score in patients with ST-segment elevation myocardial infarction (STEMI) by examining their cytokine profiles. Upon admission, patients were evaluated for systemic inflammation using a risk score that assigned points based on specific biomarkers: 1 point for leukocyte count ≥9.3 × 10³ cells/μL, 2 points for high-sensitivity C-reactive protein (hsCRP) ≥13.0 mg/L, and 3 points for serum albumin ≤3.6 g/dL. Patients were categorized into three groups: no inflammation (0 points, n = 13), mild inflammation (1-2 points, n = 35), and severe inflammation (3-6 points, n = 26). Serum levels of 16 key cytokines were measured. Patients with higher risk scores showed elevated interleukin (IL)-6 levels (19.6 vs. 8.5 vs. 6.8 pg/mL; P = 0.021) and decreased interferon-γ-induced protein-10 (IP-10) levels (73.4 vs. 68.8 vs. 112.2 pg/mL; P = 0.011). IL-6 was positively correlated with hsCRP (ρ 0.307) and negatively correlated with albumin (ρ -0.298), while IP-10 was negatively correlated with leukocyte count (ρ -0.301). No other cytokines showed significant association with the risk score. Higher inflammation scores were also associated with an increased incidence of major adverse cardiovascular events, particularly acute heart failure. This study underscores the association between the inflammation-based risk score and cytokine levels, specifically IL-6 and IP-10, in patients with STEMI.

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.

Comparison of frontal QRS-T angle and inflammatory parameters between the patients with drug-naive first episode psychosis and healthy controls. J Electrocardiol 2023; 81:106-110. [PMID: 37677849 DOI: 10.1016/j.jelectrocard.2023.08.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2023] [Revised: 08/08/2023] [Accepted: 08/23/2023] [Indexed: 09/09/2023]
Abstract
BACKGROUND Frontal QRS-T (fQRS-T) angle is a novel marker to predict many cardiovascular diseases. The present study aims to compare the fQRS-T angle of first episode psychosis (FEP) patients and healthy controls (HC) and evaluate the relationship between fQRS-T angle and blood count-related inflammatory markers such as neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), and monocyte to high-density lipoprotein cholesterol ratio (MHR). METHODS Electrocardiogram (ECG) and complete blood count (CBC) of 63 patients who were diagnosed with drug-naive FEP in the psychiatry clinic of a training and research hospital and 78 healthy controls (HC) individuals who had applied to the health committee polyclinic for recruitment or pre-military examination between 2016 and 2021 were included. RESULTS fQRS-T angle was wider in FEP patients (55.5o) than in healthy controls (22o) (p < .001). NLR, PLR, and MHR were higher in FEP patients than in healthy controls (p = .001, p < .001, and p < .001, respectively). fQRS-T angle was positively correlated with NLR (r = 0.52 and p < .001) and MHR (r = 0.39 and p = .002) in FEP patients. NLR (t = 2.196 and p = .032) and MHR (t = 5.469 and p < .001) values were found to be the predictors of fQRS-T angle in FEP patients. CONCLUSION In summary, we can conclude that patients with FEP tend to exhibit a wider fQRS-T angle compared to their healthy controls. Additionally, the values of NLR and MHR could potentially serve as useful indicators for predicting the fQRS-T angle in FEP patients. Conducting subsequent long-term studies could provide deeper insights into the interpretation of the fQRS-T angle and its potential connection to cardiovascular diseases in schizophrenia patients.

Abstract
Background/Aim: Evidence of increased mortality in perfusion abnormalities on myocardial perfusion scintigraphy (MPS) can be found. However, electrocardiography (ECG) is a cheaper and more easily accessible examination than MPS. Fragmented QRS (fQRS) is also considered to be associated with mortality in some cardiological diseases. The present study aimed to analyze the relationship between fQRS based on electrocardiography (ECG) and mortality in patients without reversible defects whose fixed hypoperfusion/perfusion defects were diagnosed and associated with myocardial infarction (MI) based on myocardial perfusion scintigraphy (MPS).
Methods: Non-ischemic patients (2289 patients) with MI diagnoses based on scintigraphy were selected based on retrospective scintigraphy reports. The presence of fQRS was investigated in 85 patients whose 12-lead electrocardiographs could be accessed from the hospital archive, and their deaths due to all causes were questioned from the death information system. The relationship between left ventricular ejection fraction (LVEF), fQRS, type of exercise, number of leukocytes, other parameters, and mortality rates was analyzed.
Results: The numbers of living (n = 69) and deceased (n = 16) patients were obtained. They were divided into two groups: (1) surviving patients (n = 69, number of fQRS positive 42) and (2) deceased (n = 16, number of fQRS positive 11). No distributional differences were found between mortality rates and fQRS and demographic features between groups (P = 0.558). However, a statistically significant effect was observed between mortality rates and low LVEF levels, pharmacological stress, number of leukocytes, and a low HDL level.
Conclusion: The present study suggests that it may be useful to define benign features of fQRS. LVEF levels may be a very important parameter in decision-making for pharmacological stress, and its role in prediction of mortality may be higher than that obtained by fQRS.

Abstract
Aim: New parameters are emerging to predict prognosis in patients with ST-segment elevation myocardial infarction (STEMI). In this study we aimed to determine and compare the prognostic values of some metabolic indices in terms of predicting long-term mortality in patients with STEMI. Method: A total of 1900 nondiabetic patients who presented with STEMI and underwent percutaneous coronary intervention were included in the study. Multivariable Cox proportional regression analysis was used to determine and compare the predictive performance of triglyceride-glucose (TyG) index, triglyceride-high density lipoprotein ratio (Ty/HDL) and admission glucose. Results: In multivariable Cox regression analysis, the model based on TyG index had better predictive performance than the Ty/HDL and admission blood glucose. Conclusion: The TyG index is more informative than Ty/HDL and admission glucose level to predict long-term all-cause mortality.

Abstract
BACKGROUND The machine learning algorithm (MLA) was implemented to establish an optimal model to predict the no reflow (NR) process and in-hospital death that occurred in ST-elevation myocardial infarction (STEMI) patients who underwent primary percutaneous coronary intervention (pPCI). METHODS The data were obtained retrospectively from 854 STEMI patients who underwent pPCI. MLA was applied to predict the potential NR phenomenon and confirm the in-hospital mortality. A random sampling method was used to split the data into the training (66.7%) and testing (33.3%) sets. The final results were an average of 10 repeated procedures. The area under the curve (AUC) and the associated 95% confidence intervals (CIs) of the receiver operator characteristic were measured. RESULTS A random forest algorithm (RAN) had optimal discrimination for the NR phenomenon with an AUC of 0.7891 (95% CI: 0.7093-0.8688) compared with 0.6437 (95% CI: 0.5506-0.7368) for the decision tree (CTREE), 0.7488 (95% CI: 0.6613-0.8363) for the support vector machine (SVM), and 0.681 (95% CI: 0.5767-0.7854) for the neural network algorithm (NNET). The optimal RAN AUC for in-hospital mortality was 0.9273 (95% CI: 0.8819-0.9728), for SVM, 0.8935 (95% CI: 0.826-0.9611); NNET, 0.7756 (95% CI: 0.6559-0.8952); and CTREE, 0.7885 (95% CI: 0.6738-0.9033). CONCLUSIONS The MLA had a relatively higher performance when evaluating the NR risk and in-hospital mortality in patients with STEMI who underwent pPCI and could be utilized in clinical decision making.

Abstract
Background Inflammation may mediate response to acute reperfusion therapy (RT) in acute
cerebral ischaemia. Neutrophil-lymphocyte ratio (NLR), an inflammatory
biomarker, may play an important role in acute ischaemic stroke (AIS)
prognostication. Objective This meta-analysis sought to examine the effect of NLR on functional
outcomes, mortality and adverse outcomes in AIS patients receiving RT. Methods Individual studies were retrieved from PubMed/Medline, EMBASE and Cochrane
databases. Data were extracted using a standardised data sheet and
meta-analysis on association of admission (pre-RT) or delayed (post-RT) NLR
with clinical/safety outcomes after RT was conducted. Results Thirty-five studies (n = 10 308) were identified for the systematic review
with 27 (n = 8537) included in the meta-analyses. Lower admission NLR was
associated with good functional outcomes (GFOs), defined as 3-month modified
Rankin scale (mRS) 0–2 (SMD = −.46; 95% CI = −.62 to −.29; P < .0001),
mRS 0–1 (SMD = −.44; 95% CI = −.66 to −.22; P < .0001) and early
neurological improvement (ENI) (SMD = −.55; 95 %CI = −.84 to −.25; P <
.0001). Lower delayed admission NLR was also associated with GFOs (SMD =
−.80; 95%CI = −.91 to −.68; P < .0001). Higher admission NLR was
significantly associated with mortality (SMD = .49; 95%CI = .12 to .85; P =
.009), intracerebral haemorrhage (ICH) (SMD = .34; 95% CI = .09 to .59; P =
.007), symptomatic ICH (sICH) (SMD = .48; 95% CI = .07 to .90; P = .022) and
stroke-associated infection or pneumonia (SMD = .85; 95% CI = .50, 1.19; P
< .0001). Higher delayed NLR was significantly associated with sICH (SMD
= 1.40; 95% CI = .60 to 2.19; P = .001), ICH (SMD = .94; 95% CI = .41 to
1.46; P < .0001) and mortality (SMD = 1.12; 95% CI = .57 to 1.67; P <
.0001). There were variations in outcomes across RT groups. Conclusion Higher admission or delayed NLR is significantly associated with worse
morbidity, mortality and safety outcomes in AIS patients receiving RT.

Abstract
INTRODUCTION P-wave dispersion (PWD) and cardiac troponin levels are independently associated with the recurrence of atrial fibrillation (AF) in patients with paroxysmal AF (PAF). We investigated the clinical usefulness of combining PWD and cardiac troponin I to predict AF recurrence in patients presenting to the emergency department with PAF. METHODS This study included 65 patients with PAF who were divided into three groups according to baseline troponin I and PWD values (group 1, troponin I<0.11 ng/dl and PWD<44.5 ms; group II, troponin I<0.11 ng/dl and PWD≥44.5 ms, or troponin I≥0.11 ng/dl and PWD<44.5 ms; group III, troponin I≥0.11 ng/dl and PWD≥44.5 ms). RESULTS The AF recurrence rate was significantly higher in group III than in groups I and II. Multivariate analysis revealed that the troponin I and PWD values in group III (odds ratio: 7.236, 95% confidence interval: 1.879-27.861, p=0.004) were independent predictors of AF recurrence. CONCLUSIONS The combined use of PWD and basal troponin I levels is a better predictor of AF recurrence than either value alone.

Abstract
BACKGROUND Despite major advances in basic and advanced life supports, patients who survived from out-of-hospital cardiac arrest (OHCA) have still poor prognosis. Several inflammatory parameters have been used to determine early and long-term prognosis in patients with OHCA. C-reactive protein-to-albumin ratio (CAR) is also a novel marker of systemic inflammation. To our knowledge, there is no study evaluating the clinical importance of CAR in OHCA patients. AIMS To evaluate the effect of CAR on in-hospital mortality in patients with OHCA. METHODS A total of 102 patients with OHCA were included in this study. The study population was divided into two groups as survivour (n = 43) and non-survivour (n = 59) during follow-up. Complete blood cell counts, biochemical and blood gas analyses were recorded for all patients. Neutrophil to lymphocyte ratio (NLR) was calculated as the ratio of neutrophil to lymphocyte. CAR was calculated as the ratio of C-reactive protein to the albumin. RESULTS NLR (P = .012), CAR (P < .001) and serum lactate level (P = .002) were significantly higher whereas lymphocyte (P = .008) and serum albumin (P < .001) were significantly lower in the non-survivour group compared with the survivour group. Multivariate logistic regression analysis showed that NLR (odds ratio [OR]: 1.044, 95% confidence interval [CI]: 1.044-1.437, P = .013), CAR (OR: 1.971, 95% CI: 1.327-2.930, P = .001) and lactate level (OR: 1.268, 95% CI: 1.095-1.469, P = .002) were independent predictors of in-hospital mortality. CONCLUSIONS We have demonstrated for the first time that CAR was an independent predictor of in-hospital mortality in OHCA patients.

Abstract
INTRODUCTION P-wave dispersion (PWD) and cardiac troponin levels are independently associated with the recurrence of atrial fibrillation (AF) in patients with paroxysmal AF (PAF). We investigated the clinical usefulness of combining PWD and cardiac troponin I to predict AF recurrence in patients presenting to the emergency department with PAF. METHODS This study included 65 patients with PAF who were divided into three groups according to baseline troponin I and PWD values (group 1, troponin I<0.11 ng/dl and PWD<44.5 ms; group II, troponin I<0.11 ng/dl and PWD≥44.5 ms, or troponin I≥0.11 ng/dl and PWD<44.5 ms; group III, troponin I≥0.11 ng/dl and PWD≥44.5 ms). RESULTS The AF recurrence rate was significantly higher in group III than in groups I and II. Multivariate analysis revealed that the troponin I and PWD values in group III (odds ratio: 7.236, 95% confidence interval: 1.879-27.861, p=0.004) were independent predictors of AF recurrence. CONCLUSIONS The combined use of PWD and basal troponin I levels is a better predictor of AF recurrence than either value alone.

Abstract
Objective According to previous studies, anaesthesia type has an important effect on immune response. However, there are limited data determining the effect of low-flow and normal-flow desflurane anaesthesia on inflammatory parameters. This study aimed to investigate the effect of low-flow and normal-flow desflurane anaesthesia on inflammatory parameters in patients undergoing laparoscopic cholecystectomy. Methods A total of 92 patients who underwent laparoscopic cholecystectomy were retrospectively included in this study. The patients were divided into the following 2 groups according to the type of anaesthesia they received: low-flow desflurane anaesthesia group (fresh gas flow rate: 0.5 L min-1) and normal-flow desflurane anaesthesia group (fresh gas flow rate: 2 L min-1). Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) were obtained before the procedure and 6 hours after the end of the procedure for all patients. Results Although pre-procedural NLR and PLR were similar between the normal-flow and low-flow anaesthesia groups, post-procedural NLR (4.38±2.00 vs. 3.51±1.37, p=0.023) and PLR (144.38±71.04 vs. 120.58±35.35, p=0.037) were significantly higher in the normal-flow anaesthesia group. In addition, compared with pre-procedural values, post-procedural NLR (from 2.31±1.02 to 4.38±2.00, p<0.001) and PLR (from 125.60±50.97 to 144.38±71.04, p=0.017) were significantly increased in the normal-flow anaesthesia group, whereas post-procedural NLR (from 2.88±2.51 to 3.51±1.37, p=0.135) and PLR (from 121.86±42.78 to 120.58±35.35, p=0.847) did not change significantly in the low-flow anaesthesia group. Conclusion The study results indicated that postoperative inflammatory response was significantly lower with low-flow desflurane anaesthesia than with normal-flow desflurane anaesthesia.

Abstract
Fragment QRS (fQRS) complex is a myocardial conduction abnormality that indicates myocardial scar. It is defined as additional notches in the QRS complex. Though initially fQRS was defined in the setting of normal QRS duration (<120 m s), later it has been expanded to include conditions with wide QRS complexes as in bundle branch block, ventricular ectopy and paced rhythm, when more than 2 notches are present. It is an important, yet often overlooked marker of mortality and arrhythmic events in many cardiac diseases. The significance of fQRS lies in the fact that it just requires a surface ECG for its recording and the value of information about the condition of the heart it dispenses based on the clinical setting. We review the role of fQRS in predicting adverse cardiac events in various conditions.

Abstract
Background The neutrophil to lymphocyte ratio (NLR) is an indicator of systemic inflammation and a prognostic marker in patients with acute coronary syndrome (ACS). This study aims to investigate the value of NLR to predict the in-hospital and long-term prognosis in patients with ST segment elevation myocardial infarction (STEMI) after percutaneous coronary intervention (PCI) by meta-analysis. Method The studies related to the prognosis of NLR and STEMI patients published in the Pubmed, Embase, and Ovid databases before June 2017 were retrieved. The relevant data were extracted. Review Manager Version 5.3 was used for meta-analysis. Results A total of 14 studies of 10,245 patients with STEMI after PCI were included. A significant difference was observed for mortality (P < 0.001; relative risk (RR) 3.32; 95% confidence interval (CI) 2.45–4.49), hospital cardiac mortality(P < 0.001; RR 3.22; 95% CI 2.25–4.60), all mortality (P < 0.001; RR 3.23; 95% CI 2.28–4.57), major adverse cardiovascular events (MACE) (P < 0.001; RR 2.00; 95% CI 1.62–2.46), in-stent thrombosis (P < 0.001; RR 2.72 95% CI 1.66–4.44), nonfatal myocardial infarction(MI) (P < 0.001; RR 1.93; 95%CI 1.43–2.61), angina (P = 0.007; RR 1.67; 95%CI 1.15–2.41), advanced heart failure (AHF) (P < 0.001; RR 1.81; 95% CI 1.48–2.21), arrhythmia (P = 0.002; RR 1.38; 95% CI 1.13–1.69), no reflow (P < 0.001; RR 2.28; 95% CI 1.46–3.57), long-term all mortality (P < 0.001; RR 3.82; 95% CI 2.94–4.96), cardiac mortality (P = 0.004; RR 3.02; 95% CI 1.41–6.45), MACE (P < 0.001; RR 2.49; 95% CI 1.47–4.23), and nonfatal MI (P = 0.46; RR 1.32; 95% CI 0.63–2.75). Conclusions Meta-analysis shows that NLR is a predictor of hospitalization and long-term prognosis in patients with STEMI after PCI, but requires further confirmation by large randomized clinical trials.
