Inflammation plays an important role in the initiation of postoperative atrial fibrillation (PoAF) in individuals undergoing cardiac surgery, Thus, this study aimed to investigate the predictive value of the systemic immune inflammation index (SII) to develop PoAF in such patients. In total, 391 consecutive patients undergoing an isolated coronary artery bypass grafting (CABG) were retrospectively analyzed. PoAF was defined according to the current guideline. The SII is determined using the following equation: neutrophil (N) × platelet (P) ÷ lymphocyte (L). The incidence of PoAF in the present study was 24% (n=97 cases). Multivariate logistic regression analysis revealed that the SII was an independent predictor of PoAF (Odds ratio: 1.002 95% confidence interval: (1.001-1.002), p807.8 with 60.8% sensitivity and 80.9% specificity [area under the curve (AUC): 0.7107]. The AUC value of SII in detecting PoAF was much greater than the AUC values of both the neutrophil to lymphocyte ratio (NLR) and the platelet to lymphocyte ratio (PLR) (AUC: 0.6740 and AUC: 0.6426, respectively). This study revealed that SII was an independent predictor of PoAF in patients who were operated on for isolated CABG. Additionally, SII had a better discriminative ability for PoAF compared to either NLR or PLR among these cases.

Patients with atrial fibrillation (AF) constitute a significant portion of hip fracture patients, and both diseases tend to present more frequently in older age. Our goal was to evaluate the long-term mortality of patients with AF who were free from heart failure undergoing hip fracture surgery. This observational, retrospective study was done in a single research and training hospital setting. Hospital electronic health record data, National Health Registry data, and National Death Registry System data for 233 consecutive patients who were above 65 years of age and were planned to undergo surgery for hip fracture were retrieved and analyzed. An experienced cardiologist evaluated the patients prior to surgery. Each member of the research cohort was categorized into one of the two groups based on their survival status (survivor and non-survivor groups). Of the 233 cases, 89 (38.2%) who were included in the investigation died during the follow-up period. The median long-term follow-up period was 34 (12-42) months. The frequency of AF was significantly higher in the non-survivor group. In multivariable Cox regression analysis, AF (HR: 2.195, 95%CI 1.365-3.415, p<0.001), advanced age, and blood urea level were determined as independent predictors for all-cause long-term mortality. AF is an independent predictor for long-term death in hip fracture cases above 65 years of age who were free from heart failure.

This study compares conventional coronary artery bypass grafting (CABG) with port access CABG via a left anterior small thoracotomy in patients requiring surgical multivessel revascularization. Clinical, neuropsychological, and angiographic outcomes were studied, as well as parameters of myocardial and cerebral protection. Pathogenicity of cardiopulmonary bypass (CPB) was further evaluated by measuring parameters of peripheral limb ischemia and inflammatory whole-body response. In a prospective randomized study, 40 patients who required multivessel CABG were assigned to either conventional CABG via complete median sternotomy (group A) or port access CABG via minithoracotomy (group B). Control angiograms were performed in group B only. In addition, patients underwent neuropsychological testing after the operation. CK, CK-MB, and Troponin T levels were documented. S-100B protein and neuron-specific enolase (NSE) served to quantify cerebral injury. The terminal complement complex (C5b-9) and myeloperoxidase concentrations were determined to analyze inflammatory whole-body response after CPB. There was no mortality. One patient suffered a retrograde aortic dissection immediately after onset of CPB, but had an uneventful postoperative course after surgical repair. Troponin T and CK-MB showed no difference between groups. CK and myoglobin were significantly higher in the minimally invasive cohort. Changes in complement activation (C5b-9) and myeloperoxidase during CPB markers of the whole-body inflammatory response were similar in both groups. S-100B concentrations in the port access group were significantly higher, whereas NSE levels were similar in both groups. Both groups did not display any significant difference in neuropsychological testing. Minimally invasive multivessel CABG via minithoracotomy using port access technology is feasible and safe. Though prolonged operating and CPB times with significantly higher S-100B concentrations were observed in group B, equivalent myocardial and cerebral protection and similar whole-body inflammatory response were documented.

Background and Objectives: Studies have shown that inflammation markers can be used as prognostic tools in predicting acute ischemic stroke. In this study, we conducted a comparison of several inflammation scores in predicting left atrial thrombosis (LAT) in patients with ischemic stroke without AF. Materials and Methods: In this single-center, retrospective study, we included 303 consecutive patients with ischemic stroke. Each patient underwent a transesophageal echocardiography (TEE) examination within 10 days of admission to detect the presence of LAT. To identify independent predictors of LAT, we conducted a multivariate logistic regression analysis. Results: In total, 303 patients who had ischemic stroke were included in the analysis. LAT was detached in 34 patients at the time of the TEE examination. The patients were categorized into two groups based on their LAT status. The Prognostic Nutritional Index (PNI), HALP score, and C-reactive Protein–Albumin Ratio (CAR) were identified as statistically significant predictors of LAT. Based on the results of the multivariate regression analysis, the CAR emerged as the only independent predictor of LAT. Conclusions: Among several inflammation scores, the PNI, HALP, and CAR were statistically significant predictors of LAT in ischemic stroke patients without AF. CAR was identified as the optimal score for the prediction of LAT in patients with stroke and without AF.
