Background: Even though medication and interventional therapy have improved the death rate for non-ST elevation myocardial infarction (NSTEMI) patients, these patients still have a substantial residual risk of cardiovascular events. Early identification of high-risk individuals is critical for improving prognosis, especially in this patient group. The focus of recent research has switched to finding new related indicators that can help distinguish high-risk patients. For this purpose, we examined the relationship between the pan-immune-inflammation value (PIV) and the severity of coronary artery disease (CAD) defined by the SYNTAX score (SxS) in NSTEMI patients. Methods: Based on the SxS, CAD patients were split into three groups. To evaluate the risk variables of CAD, multivariate logistic analysis was employed. Results: The PIV (odds ratio: 1.003; 95% CI: 1.001–1.005; p = 0.005) was found to be an independent predictor of a high SxS in the multivariate logistic regression analysis. Additionally, there was a positive association between the PIV and SxS (r: 0.68; p < 0.001). The PIV predicted the severe coronary lesion in the receiver-operating characteristic curve analysis with a sensitivity of 91% and specificity of 81.1%, using an appropriate cutoff value of 568.2. Conclusions: In patients with non-STEMI, the PIV, a cheap and easily measured laboratory variable, was substantially correlated with a high SxS and the severity of CAD.

Background: Inflammatory markers may provide insights into the underlying mechanisms of slow coronary flow (SCF), including subclinical atherosclerosis and endothelial dysfunction. Interleukin-34 (IL-34), known for its role in immuno-inflammatory diseases, might hold significance in SCF. We aimed to explore the potential association between IL-34 and SCF in patients undergoing diagnostic elective coronary angiography. Methods: This observational, cross-sectional study enrolled 256 participants: 124 with SCF and 132 with normal coronary flow (NCF). All participants had undergone outpatient coronary angiography for suspected coronary artery disease. SCF assessment employed the TIMI frame count (TFC) for quantifying coronary flow rate. Results: SCF patients exhibited significantly elevated TFC in all three major coronary arteries compared to controls (p < 0.05). IL-34 displayed a noteworthy positive correlation with average TFC [for all participants: r = 0.514, p < 0.001; for SCF patients: r = 0.526, p < 0.001; for normal controls: r = -0.288, p > 0.05]. Similarly, high-sensitivity C-reactive protein (hsCRP) showed a significant and positive relationship with average TFC [for all participants: r = 0.504, p < 0.001; for SCF patients: r = 0.558, p < 0.001; for normal controls: r = -0.148, p > 0.05]. SCF patients presented coronary arteries of larger size compared to controls. Conclusion: Mean coronary diameter and IL-34 emerged as independent predictors of SCF. Additionally, hsCRP, mean coronary diameter, and IL-34 exhibited a positive correlation with mean TFC values. IL-34 appears to be a more effective indicator than hsCRP in SCF patients.

İntroduction: Patients with normal coronary arteries in whom increased vasospasm cannot be detected with the stress test should be evaluated in terms of cardiac syndrome x (CSX). İnflammatory systems are effective in endothelial activation and dysfunction in CSX. The systemic immune inflammation index (SII) is thought to be an important factor in determining the course of diseases, especially in infectious diseases or other diseases, as an indicator of the inflammation process. The aim of this study is to determine the role of SII levels in the diagnosis of CSX disease. Methods: The study group included 80 patients who applied to the cardiology department of Fırat University with typical anginal complaints between October 2021 and April 2022, and were diagnosed with ischemia after the myocardial perfusion scan, and then coronary angiography was performed and normal coronary arteries were observed. Results: When the study and control groups were examined according to age, gender and body mass index, hypertension, smoking, diabetes mellitus, dyslipidemia and family history, no statistical significant difference was observed between the groups. It was observed that there was a significant difference between the high sensitive C- reactive protin levels of the individuals in the study and control groups (p = 0.028). SII levels measured in samples taken from patients were significantly higher than control subjects (p = 0.003). SII cutoff at admission was 582 with 82% sensitivity and 84% specificity (area under the curve 0.972; 95% CI:0.95–0.98;p < 0.001). Conclusion: It has been demonstrated that systemic SII parameters, which can be simply calculated with the data obtained from the complete blood count and do not require additional costs, can contribute to the prediction of CSX disease.

Background: This study aimed to investigate the relationship between neutrophil percentage-to-albumin ratio (NPAR) and collateral circulation in patients with chronic total occlusion (CTO). Chronic total occlusion is an advanced stage of coronary artery disease (CAD) and is characterized by complete occlusion of the coronary arteries. Collateral circulation provides alternative routes that supply blood flow instead of occluded arteries and may affect the prognosis of CTO patients. Neutrophil percentage-to-albumin ratio is recognized as an indicator of inflammation and can be used to predict the prognosis of various diseases. Methods: In this retrospective study, 320 patients with CAD who were diagnosed with CTO by coronary angiography were included. Demographic characteristics, clinical findings, and laboratory test results were recorded. The degree of coronary collateral circulation was classified according to the Cohen-Rentrop method. Neutrophil percent-age-to-albumin ratio and other inflammatory parameters were measured. The relationship between NPAR and collateral circulation was evaluated using multivariate analysis. Results: Neutrophil percentage-to-albumin ratio levels were significantly associated with poor collateral circulation. Neutrophil percentage-to-albumin ratio, together with other inflammatory parameters (white blood cell count, neutrophil-to-lymphocyte ratio, C-reactive protein), was identified as an independent marker of poor collateral circulation in CTO patients. Fasting blood glucose levels and diabetes mellitus were also associated with poor collateral circulation. Conclusion: Neutrophil percentage-to-albumin ratio is emerging as a simple and effective inflammatory marker that can be used to predict the quality of collateral circulation in CTO patients. This is important for predicting the prognosis of CTO patients and the success of percutaneous revascularization. However, more extensive studies are needed.

Introduction: Although patients with myocardial infarction (MI) history exhibit individual differences, several psychological problems can be observed in these patients. The present study aimed to investigate the correlation between defence mechanisms and other clinical and sociodemographic data in the early period in patients with MI history.Material and methods: Sixty patients diagnosed with MI and hospitalized in the cardiology department were included in the study. The Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), and Defence Styles Questionnaire (DSQ) were applied.Results: It was determined that the mean BDI score of the participants was 15.9 ±11.2, and the mean BAI score was 15.98 ±10.9. There was a positive correlation between the depression and immature defence mechanism scores of the patients, and there was a negative correlation between the depression and mature defence mechanism scores of the patients (p = 0.001, r = 0.412; p = 0.005, r = –0.359). A negative correlation was determined between anxiety scores and mature defence mechanism scores (p = 0.002, r = –0. 397).Conclusions: The findings demonstrated that depressive complaints of the post-MI patients increased as the immature defence mechanism score increased, and depressive complaints decreased as the maturity defence mechanism score increased. The correlation between the defence mechanisms adopted by MI patients and depression and anxiety symptoms should not be neglected.
