Background: After coronary artery bypass graft (CABG) operations, acute kidney injury (AKI) appears at 5-30% rates, and this rate increases even more in patients with diabetes mellitus (DM). Prognostic nutritional index (PNI) is known as a valuable parameter that affects cardiovascular surgery outcomes. In this current study, we aimed to investigate the importance of PNI value in predicting AKI after on-pump CABG operations in insulin-dependent diabetic patients. Methods: A total of 254 consecutive patients with insulin-dependent diabetes who underwent on-pump CABG in our clinic between January 2016 and January 2020 retrospectively were included in this study. In the postoperative period, patients were registered as the renal failure group (Group 1), and those who did not develop renal failure were registered as Group 2. Results: A total of 255 patients with DM were included in the study. There were 82 patients in Group 1 and 173 patients in Group 2. There was no difference between the groups, in terms of age, gender, smoking, and hyperlipidemia rates. Hypertension rate significantly was higher in Group 2 (P = .001). In multivariate logistic regression analysis, hypertension (OR: 1.226, 95% CI: 1.114-2.459, P = .026), need for inotropic support (OR: 1.128, 95% CI: 1.070-1.784, P = .033), increased blood product use (OR: 1.291, 95% CI: 1.112-2.156, P = .021) preoperative high creatinine (OR: 3.563, 95% CI: 2.497-5.559, P < .001), and PNI (OR: 1.327, 95% CI: 1.118-2.785, P = .012) were independent predictors of AKI. Conclusion: In our study, we determined PNI value as an independent predictor in predicting acute renal injury occurring after on-pump CABG operations in patients with insulin-dependent DM.

Nutritional problem of the patient is a valuable stiuation in patients undergoing surgery. In this study, we aimed to investigate the relationship between prognostic nutritional index (PNI) and postoperative in-mortality in patients undergoing cardiac surgery. 1003 patients undergoing on-pump cardiac surgery in our hospital between January 2016-January 2020 were included in this study retrospectively. Patients were divided into two groups based on in-hospital mortality, as survivors (Group I, n = 934) and non-survivors (Group II, n = 69). Their preoperative nutritional status was determined using the PNI. Compared to survivors, non-survivors were found to have a significantly higher mean age (62.5 ± 10.8 vs. 67.45 ± 10.1, P < 0.001) and significantly lower mean preoperative ejection fraction (51.6 ± 0.3 vs. 44.5 ± 1.2, P < 0.001). And combined cardiac surgery rate was significantly higher in non-survivors (P = 0.009). Also nonsurvivors had a significantly lower mean PNI compared to survivors (44.76 ± 7.63 vs. 48.34 ± 6.71, P < 0.001). Multivariate analysis Model 1 revealed that age (Odds ratio (OR): 1.

Objectives Postoperative atrial fibrillation (PoAF), an important clinical condition that can occur after coronary artery bypass graft (CABG) operations, may bring about cerebrovascular risks, prolong hospital stay and increase treatment costs. In this prospective study, we aimed to investigate the predictive value of HATCH score and waist/height ratio (WHR) values in revealing the development of PoAF after CABG operations. Methods Patients who underwent isolated CABG surgery with cardiopulmonary bypass between May 2019 and November 2019 were prospectively included in the study. Preoperative demographic characteristics, laboratory parameters, and operative parameters of the patients were recorded prospectively. Results A total of 255 patients were included in the study. Those who did not develop PoAF were included in Group 1 (N = 196, mean age = 58.9 ± 9.4 years), and those who did were included in Group 2 (n = 59, mean age = 61.1 ± 12 years). There were no statistically significant differences between the two groups in terms of age, gender, presence of hypertension and hyperlipidemia. Rates of chronic obstructive pulmonary disease and previous percutaneous coronary interventions, waist circumference, waist to height ratio and HATCH score values were significantly higher in Group 2 compared to Group 1 ( p values: 0.019, 0.034, 0.001, <0.001, <0.001, respectively). In multivariate analysis, WHR (Odds ratio: 1.068, Confidence interval: 1.032–1.105, p < 0.001) and HATCH score (Odds ratio: 2.590, Confidence interval: 1.850–3.625, p < 0.001) were independent predictors of PoAF. Conclusions With this current prospective study, we showed that calculating WHR and HATCH score in the preoperative period can help us predict PoAF.
