Background: The nutritional status of the patient is an important parameter in patients undergoing surgery. This study aims to determine of prognostic nutritional index value that predicts hospital mortality and morbidity in on-pump cardiac surgery. Methods: In this study, we scanned the medical data of 1003 patients who underwent on-pump cardiac surgery. Patients’ divided into two groups according to in-hospital mortality. 934 patients without in-hospital mortality were defined as Group I, and 69 patients who died in the hospital were defined as Group II. Their preoperative nutritional status was determined using the prognostic nutritional index classification. Results: In our series, age is statistically higher in Group II rather than Group I (62.5 ± 0.3 vs. 67.4 ± 1.2; p=0.001). There was a significantly different a higher tendency of hospital-acquired infection in Group II (151; 16.2% vs. 44; 63.8%; p=0.001). Postoperative stroke significantly higher in Group II (35; 3.7% vs. 62; 89.9%; p=0.001). Multivariate analysis revealed that cross clamp time, cardiopulmonary bypass time, intraaortic balloon pump usage and intensive care unit stay significantly higher in Group II (p<0.05, respectively). The prognostic nutritional index value was found statistically low in Group II (48.34 ± 6.71 vs. 44.76 ± 7.63; p=0.001). Multivariate analysis revealed that male gender, age, and the prognostic nutritional index were independently associated with postoperative survival. Conclusion: In on-pump cardiac surgery, postoperative mortality and morbidity are significantly associated with preoperative low prognostic nutritional index, and the prognostic nutritional index can be a useful and suitable parameter for preoperative risk evaluation.

Abstract Aim: The prevalence of atrial fibrillation (AF) in patients with myocardial infarction (MI) ranges widely and has been reported to be as high as 21%. However, the demographic, clinical, and angiographic characteristics of AF patients with de novo MI is unclear. The aim of this study was to investigate the prevalence of patients presenting with de novo MI with AF. Methods: The study was performed as a sub-study of the MINOCA-TR (Myocardial Infarction with Non-obstructive Coronary Arteries in Turkish Population) Registry, a multicenter, cross-sectional, observational, all-comer registry. MI patients without a known history of stable coronary artery disease and/or prior coronary revascularization were enrolled in the study. Patients were divided into AF and Non-AF groups according to their presenting cardiac rhythm. Results: A total of 1793 patients were screened and 1626 were included in the study. Mean age was 61.5 (12.5) years. 70.7% of patients were men. Prevalence of AF was 3.1% (51 patients). AF patients were older [73.4 (9.4) vs. 61.0 (12.4) years, p<0.001] than non-AF patients. The proportion of women to men in the AF group was also higher than in the non-AF group (43.1% vs. 28.7%, p=0.027). Dramatically, the minority of patients were previously diagnosed with AF (14 patients, 27.4%) and only 1 out of every 5 AF patients (10 patients, 19.6%) was using oral anticoagulants (OAC). Conclusions: AF prevalence in patients presenting with de novo MI was lower than reported in previous studies. The majority of AF patients did not have any knowledge of their arrhythmia and were not undergoing OAC therapy at admission, emphasizing the vital role of successful diagnostic strategies, patient education, and implementations for guideline adaptation.
