Backround: Postoperative atrial fibrillation (PoAF), the most common arrythmia observed in 18-40% of patients following coronary artery bypass surgery, may cause hemodynamic disturbances and increase embolism risk. The aim of this study was to investigate the relationship of HATCH score with PoAF in patients who underwent off-pump coronary artery bypass grafting (OPCABG) and evaluate the effect of preoperatively calculated neutrophil-to-lymphocyte ratio (NLR) on PoAF. Methods: Patients who underwent OPCABG between January 2014 and January 2019 were included in the study. Preoperative and postoperative data retrospectively were obtained. Patients who did not develop PoAF during the postoperative hospitalization period constituted Group 1; those who did were classified as Group 2. Results: Ninety-seven patients (69 males and 28 females) with a mean age of 54.4 ± 11.1 years constituted Group 1, and 26 patients (17 males and 9 females) with a mean age of 61±12.6 years constituted Group 2. Significant differences were observed between the 2 groups, in terms of age and HATCH scores (P = .025 and P < .001, respectively). NLR, number of distal anastomoses, intensive care unit (ICU) stay times, and total hospitalization times were significantly higher in Group 2 (P = .021, P = .021, P < .001, P < .001, respectively). HATCH score was identified as an independent predictor of AF development following OPCABG surgery (OR: 2.125, 95 % CI: 1.296–3.482, P = .003). Conclusion: In light of our study, HATCH scores of all patients preoperatively may be calculated so that preventive precautions are taken for high-risk patients.

Background: Aortic dissection is a cardiovascular disease with high mortality and morbidity rates. The aim of this study is to investigate the role of C-reactive protein (CRP) and neutrophil-to-lymphocyte ratio (NLR) in predicting in-hospital mortality in patients undergoing emergent surgery for Stanford type A aortic dissection. Methods: Patients operated for acute Stanford type A aortic dissection between January 2010 and December 2018 were included in the study. Patients without in-hospital mortality were classified as Group 1, and patients with mortality were classified as Group 2. Results: One-hundred-eighteen patients were involved in the study. Patient mean age was 57 ± 11.7 years, and 89 patients (75.4%) were male. Neutrophil-to-lymphocyte ratio (NLR), white blood cell (WBC), neutrophil counts, and C-reactive protein (CRP) values at the time of admission also were found to be high in Group 2 (P = .001, .021, < .001, < .001 respectively). Total perfusion times (TPt), antegrade cerebral perfusion time (ACPt), cross-clamp time (CCt), and intensive care unit (ICU) stay periods significantly were higher in the mortality group (P < .001, < .001, = .01, and < .001, respectively). In receiver-operating characteristic (ROC) curve analysis, a cut-off level of 23 mg/L was determined for CRP levels that predict progression to mortality (area under the curve (AUC): 0.879, P < .001, 75.0% sensitivity and 58.0% specificity). Similarly, a cut-off level of 8.8 was found for NLR that predicts progression to mortality (AUC: 0.835, P < .001, 76.0% sensitivity and 61.0% specificity). Conclusion: As a result, we can use CRP and NLR values, which easily can be measured or calculated from blood tests to predict mortality in patients with aortic dissections, which may have serious mortal consequences.

Delayed surgical closure following VAC therapy may be associated with shorter hospitalization and lower mortality in patients with deep sternal wound infection. Additional operation, diabetes mellitus, and a high level of EuroSCORE were associated with mortality.

OBJECTIVE: Many laboratory parameters allow to follow up the course of the disease and reveal its clinical severity, particularly in patients with coronavirus disease 2019 (COVID-19) pneumonia. In this study, we aimed to investigate the role of the blood urea nitrogen-to-albumin ratio in predicting the mortality in COVID-19 patients with moderate-to-severe disease who are hospitalized in the intensive care unit.METHODS: A total of 358 patients who were hospitalized in intensive care unit at our hospital between November 1, 2020 and May 15, 2021 were included in this study. During their course of intensive care, surviving patients were included in Group 1 and nonsurviving patients in Group 2.RESULTS: There were no statistically significant differences between the two groups in terms of gender, smoking, and chronic obstructive pulmonary disease rates. In multivariate logistic regression analysis, advanced age (OR 1.038, 95%CI 1.014-1.064, p=0.002), neutrophilto-lymphocyte ratio (OR 1.226, 95%CI 1.020-1.475, p=0.030), blood urea nitrogen-to-albumin ratio (OR 2.693, 95%CI 2.019-3.593, p<0.001), and chest computed tomography severity score (OR 1.163, p<0.001) values were determined as independent predictors for in-hospital mortality.CONCLUSION: In this study, we showed that the blood urea nitrogen-to-albumin ratio, which was previously shown as a predictor of mortality in patients with various pneumonia, was an independent predictor of mortality in patients with COVID-19 pneumonia.

Severe acute respiratory syndrome-associated coronavirus-2 (SARS-CoV-2) causes coronavirus disease 2019 (COVID-19), which has been considered a pandemic by the World Health Organization (WHO). Clinical manifestations of COVID-19 disease may differ, most cases are mild, but a significant minority of patients may develop moderate to severe respiratory symptoms, with the most severe cases requiring intensive care and/or mechanical ventilatory support. In this study, we aimed to identify validity of our modified scoring system for foreseeing the approach to the COVID-19 patient and the disease, the treatment plan, the severity of morbidity and even the risk of mortality from the clinician's point of view. In this single center study, we examined the patients hospitalized with the diagnosis of COVID-19 between 01/04/2020 and 01/06/2020, of the 228 patients who were between 20 and 90 years of age, and whose polymerase chain reaction (PCR) tests of nasal and pharyngeal swab samples were positive. We evaulated 228 (92 male and 136 female) PCR (+) patients. Univariate analysis showed that advanced age (p < 0.001), hemoglobin (p < 0.001), troponin-I (p < 0.001), C-reactive protein (CRP) (p < 0.001), fibrinogen (p < 0.001), HT (p = 0.01), CAD (p = 0.001), DM (p < 0.001), history of malignancy (p = 0.008), along with m-sPESI scores (p < 0.001) were significantly higher in patients that needed intensive care due to COVID-19 infection. In the multivariable logistic regression analysis, only the m-sPESI score higher than ≥ 2 was found to be highly significant in terms of indicating the need for ICU admission (AUC 0.948; 84.6% sensitivity and 94.6% specificity) (p < 0.001). With an increasing number of hospitalized patients, healthcare providers are confronting a deluge of lab results in the process of caring for COVID-19 patients. It is imperative to identify risk factors for mortality and morbidity development. The modified sPESI scoring system, which we put forward, is successful in predicting the course of the disease at the presentation of the patient with COVID-19 disease and predicting the need for intensive care with high specificity and sensitivity, can detect the need for intensive care with high specificity and sensitivity.

Objectives: This study aimed to investigate the early results of the patients presented with acute coronary syndrome (ACS) who underwent coronary artery bypass grafting (CABG) after percutaneous coronary intervention (PCI) to the culprit lesion. Methods: Patients who underwent CABG between January 2011 and January 2014 were enrolled and divided into two groups. Group 1 (102 patients) was consist of the patients who were hospitalized with ACS and underwent CABG after a previous PCI. Group 2 (107 patients) was consisting of the patients who underwent elective CABG operation after elective coronary angiography. Results: There was no statistically significant difference between the groups in terms of demographic features and preoperative risk factors. Preoperative use of angiotensin-converting enzyme inhibitor and levosimendan were significantly higher in group 1 compared to group 2. (95 (93.1%) vs. 89 (83.1%), p = 0.027). The operative variables were similar between two groups whereas the postoperative blood drainage amounts were significantly higher in group 1 than group 2 (546.3 ± 172 cc vs. 424.2 ± 185 cc, respectively, p < 0.001). The blood product usage was significantly higher in group 1 than in group 2 (3.3 ± 1.8 units vs.1.7 ± 0.9 units, respectively, p < 0.001). Conclusions: Early CABG operation after ACS is a safely applicable process with acceptable mortality and complication rates. Keywords: Early CABG operation after ACS is a safely applicable process with acceptable mortality and complication rates.ardiovascular Diseases (CVDs) are the most common cause of mortality in developed countries as it is the expected case to be valid in developing countries in the future [1]. Coronary artery disease (CAD) is the most common form of cardiovascular diseases which is associated with high mortality and morbidity all over the world. Ischemic heart disease may clinically manifests as silent ischemia, stable angina pectoris, unstable angina pectoris, myocardial infarction (MI), heart failure, or sudden cardiac death. Acute coronary syndrome (ACS) is the name of a group of diseases that show different clinical manifes-C
