Objective: The neutrophil -to-lymphocyte ratio (NLR) is a new predictor for cardiovascular risk and mortality. The SYNTAX score is an angiographic tool used in grading the complexity of coronary artery disease (CAD). However, its relation with CAD severity and complexity is not yet known. We hypothesized that NLR would be associated with a greater complexity of CAD as assessed using the SYNTAX score. Methods: This cross-sectional observational study included 106 patients who had undergone coronary angiography for stable angina pectoris and 69 patients who had normal coronary angiogram. Baseline NLR was measured by dividing neutrophil count to lymphocyte count. The patients were classified two groups as CAD (-) (n=69) and CAD (+) (n=106), then patients in CAD (+) group were divided into 3 groups according to SYNTAX scores (SYNTAX score 1-22, 23-32, >32) as pointed in European Society of Cardiology (ESC) revascularization guideline. Statistical analysis was performed using the Mann-Whitney U and Kruskal-Wallis tests, and multiple logistic regression analysis was used to identify the independent predictors of complexity of CAD-SYNTAX score. Results: Patients with CAD had a significantly higher value of NLR [1.6 median (1.2-3.3 IQR) vs. 2.3 median (1.8-3.0 IQR) p<0.001]. The group with high SYNTAX scores (>32) more frequently had diabetes mellitus (DM), hypercholesterolemia (HL), were of older age, and also had significantly elevated NLR values [2.4 (1.3-2.6), 2.6 (2.3-3.9), 2.0 (1.5-2.6) p=0.006]. In univariate analysis, age, DM, HL, creatinine, neutrophil count and NLR were predictors of high SYNTAX score. In the multiple logistic regression analysis, only NLR [odds ratio (OR)=2.1, 95% confidence interval (CI) 1.2-3.8, p=0.09], was identified as independent predictor of a high SYNTAX score. Conclusion: NLR is a strong clinical laboratory value that is associated with presence and complexity of CAD.

SYNTAX skoru koroner arter hastalığı (KAH) karmaşıklığını derecelendirmede anjiyografik bir yöntemdir. NLO ile KAH varlığı ve karmaşıklığı arasındaki ilişki henüz ortaya konmamıştır. Biz SYNTAX skorunu kullanarak NLO ile KAH varlığı ve karmaşıklığı arasında daha güçlü bir ilişki olabileceği tezini öne sürdük.

Bazal NLO nötrofil sayısının lenfosit sayısına oranı olarak hesaplandı. Hastalar KAH olan ve olmayan şeklinde iki gruba ayrıldı. KAH grubu SYNTAX skoruna göre Avrupa Kardiyoloji Cemiyeti miyokardiyal girişim kılavuzuna dayanarak 3 gruba ayrıldı (23)(24)(25)(26)(27)(28)(29)(30)(31)(32) >32).

PS patients demonstrate reduced cardiac contractility, independent of CMR-proven structural cardiac lesions, while patients with structural lesions have a more pronounced drop in strain parameters. Tn-C and Gl-3 are promising markers for the diagnosis of PS, but they are not specific for cardiac involvement.

Background: Coronary ischemia can lead to myocardial damage and necrosis. The pathogenesis of cardiovascular diseases often includes increased oxidative stress and decreased antioxidant defense. The study aimed to assess levels of ischemia modified albumin (IMA), malondialdehyde acid (MDA), superoxide dismutase (SOD), and catalase in individuals diagnosed with ST elevated myocardial infarction (STEMI) and non-STEMI. Methods: The present study prospectively included 50 STEMI patients, 55 NSTEMI patients, and 55 healthy subjects. Only patients who were recently diagnosed with STEMI or NSTEMI were included in this study. IMA, MDA, SOD, and catalase activities were measured spectrophotometrically. Significant coronary artery lesions were determined by angiography. Results: Patients with ACS had significantly greater IMA and MDA values than the healthy controls (p<0.001). In addition, patients with STEMI had IMA levels that were significantly greater than those of the patients with NSTEMI (p <0.001), while the reverse was true for MDA levels (p<0.001). The healthy controls had the highest levels of SOD and catalase levels, followed by patients with STEMI and patients with NSTEMI, respectively (p <0.001). There was a significant negative correlation among MDA and SOD with catalase levels (r = -0.771 p <0.001 MDA vs catalase; r = -0.821 p <0.001 SOD vs catalase). Conclusions: Data obtained in this study reveals that compared to healthy controls, STEMI and NSTEMI patients had increased levels MDA and IMA, and decreased levels of SOD and catalase.

Background: Index of cardio-electrophysiological balance (iCEB) has been described as a novel risk marker for predicting malignant ventricular arrhythmia. There remains limited evidence on the effects of amiodarone and propafenone used for sinus rhythm maintenance on iCEB in patients with atrial fibrillation (AF). The aim of this study was to evaluate iCEB in patients with AF on antiarrhythmic-drug therapy.Methods: A total of 108 patients with AF (68 patients using amiodarone and 40 patients using propafenone) and 50 healthy subjects were included in the study. All groups underwent a standard 12-lead surface electrocardiogram. QRS duration, QT, T wave peak-to-end (Tp-e) intervals, iCEB (QT/QRS) and iCEBc (heart rate-corrected QT (QTc)/QRS) rates were calculated from the electrocardiogram and compared between groups.Results: QT, Tp-e intervals and Tp-e/QT ratio were significantly longer in the amiodarone group than the propafenone and control groups (P < 0.001, for all). iCEB was similar in the amiodarone and control groups (4.4 ± 0.6 and 4.2 ± 0.4; P > 0.05), while iCEB values in the propafenone group were significantly lower than the amiodarone group and control groups (3.9 ± 0.5; P < 0.001). There was a significantly difference in iCEBc values among the amiodarone, control and propafenone groups (4.8 ± 0.6, 4.6 ± 0.4 and 4.3 ± 0.6; P < 0.001, respectively).Conclusions: In this study, higher iCEBc parameters were observed in patients using amiodarone, while iCEBc values were lowest among patients with AF using propafenone. Further studies are needed to determine whether these electrophysiological changes are associated with ventricular arrhythmias for patients with AF on antiarrhythmicdrug therapy.
