Background/Objectives: The Charlson Comorbidity Index (CCI) is designed for evaluating comorbidities and mortality risks, with the age-adjusted CCI (ACCI) combining age and comorbidity assessments. Despite its long-standing use, research on CCI’s application in cardiac surgery patients is limited. This study assessed the effectiveness of CCI and ACCI in predicting in-hospital mortality and post-surgery outcomes for patients undergoing isolated coronary artery bypass grafting (CABG). Methods: CCI and ACCI scores were derived from medical records between 2016 and 2022. Patient demographics, surgical techniques, and postoperative complications were documented. Results: Totally 393 patients [297 (75.6%) males, 96 (24.4%) females] with an average age of 65 years were included. Median CCI and ACCI scores were 1 (1–2) and 4 (3–5), respectively. In-hospital mortality occurred in 5.9% (n = 23) of cases, with CCI being an independent predictor (OR 1.865, 95% CI 1.117–3.116; p = 0.017). Both CCI and ACCI scores negatively correlated with preoperative EF (%) and positively correlated with ICU and total hospital stay, cardiopulmonary bypass time, and cross-clamp time. ACCI score also positively correlated with extubation time. Patients categorized by CCI comorbidity severity (no comorbidity, mild, moderate, severe) showed a significant increase in postoperative complications with increasing severity, including postoperative VT (p = 0.000), acute renal failure (p = 0.009), pneumonia (p = 0.007), and in-hospital mortality (p = 0.001). Conclusions: Both CCI and ACCI are prognostic indicators for in-hospital mortality in isolated CABG surgery patients, effectively predicting postoperative complications, extended ICU stays, and prolonged hospital stays. Implementing these scoring systems could enhance patient care and improve surgical decision-making.

Objective: Polyhexamethylene biguanide (PHMB) is a novel wound antiseptic solution that has a broad antimicrobial spectrum and wound healing promoting effect, with minimal side effects. The aim of present study was to demonstrate the efficacy of the PHMB on the bacterial burden of non-healing wounds, the reduction in wound size or closure of the wound in comparison to Ringer's lactate solution (RLS) after 21 days of wound dressing. A second objective was to investigate the differences in the C-reactive protein (CRP) levels and white blood cell (WBC) counts between the two groups. Method: In this prospective and open-cohort clinical study, patients who underwent cardiac surgery between July 2006 and August 2008 were included and placed in one of two groups, PHMB or RLS, by the block randomisation method. A wound care team, consisting of two surgeons, a wound care nurse and a microbiologist, was created. Classic moist dressings and wet compresses during dressing changes were applied at least once a day or as needed. During the 21 days of hospitalisation the team collected data on the wound healing status daily, on infection parameters every third day, and wound tissue for culture weekly. Results: There were 40 patients recruited of which 9 were excluded, leaving 31 in the intention-to-treat analysis. Of these 15 received PHMB and 16 received RLS. Overall 17 of 31 (66.7% PHMB group, 43.8% RLS group, p=0.181) patients were treated successfully by closure of surgically sutured wounds or healing by secondary intention, the wound tissue cultures of 19 of 31 patients (47.4% PHMB, 52.6% RLS, p=0.886) were negative, and wound size of all the patients were significantly reduced in clinical observations. Although the CRP levels were reduced significantly within group comparisons in both groups (p<0.001), it was significantly lower after 12 days (p<0.05) in the PHMB group compared with the RLS group. Conclusion: The results of this study emphasise that the successful treatment of chronic non-healing wounds require a multidisciplinary team approach under the control of a wound care specialist. Whatever the disinfectant used, consistency in the approach to treatment may be more important. We suggest that increasing the use of PHMB and adoption of this team approach in other cardiac centres or other populations may decrease the healing period, especially in chronic non-healing wounds.

Background: The lactate dehydrogenase to albumin ratio (LAR) is a novel inflammatory marker and a potential predictor of mortality in various conditions. No research has yet examined LAR’s impact on mortality in cardiac surgery patients. This study evaluated LAR’s role in predicting mortality and complications in isolated coronary artery bypass grafting (CABG) patients. Methods: A retrospective analysis of 377 CABG patients (93 women, 24.7%; 284 men, 75.3%; mean age 65.9 years) from 2020 to 2024 was conducted. Data included demographics, preoperative characteristics, surgical details, and postoperative outcomes, along with ICU and hospital length of stay (LOS). Results: In-hospital mortality was 6.1% (n = 23). Independent predictors were low preoperative ejection fraction (EF) (OR: 0.96, p = 0.024), baseline LAR (OR: 1.08, p = 0.000), LOS-ICU (OR: 1.1, p = 0.000), postoperative ventricular tachycardia (OR: 37.9, p = 0.006), and acute renal failure (OR: 12.1, p = 0.000). Mortality cases had a higher median LAR than survivors (8.6 vs. 5.2, p = 0.000). Elevated LAR correlated with lower preoperative EF (r = −0.227, p = 0.000), longer LOS-ICU (r = 0.17, p = 0.001), and longer LOS-hospital (r = 0.208, p = 0.000). A LAR cut-off of 7.097 predicted mortality (AUC: 0.823, sensitivity 78.3%, specificity 77.1%). Elevated LAR values were observed in all groups with postoperative complications (p < 0.05), indicating its consistent association with negative outcomes. Conclusions: LAR is a valuable predictor of in-hospital mortality and postoperative complications in CABG patients. Elevated LAR is associated with longer ICU/hospital stays and poorer outcomes. Preoperative LAR assessment can guide risk stratification, forecast mortality, and inform surgical planning and treatment strategies.

Introduction: Patients experience muscle, joint and shoulder pain after heart surgery. We aimed to compare quality of life in 2 groups of patients, one group having an internal mammary artery (IMA) retractor during surgery, the second group undergoing non-coronary heart surgery.Material and methods: Group 1 was composed of 39 patients receiving an IMA retractor whereas in group 2 there were 29 patients. Patients in groups were compared for postoperative quality of life, shoulder pain, functional status, strength and patient satisfaction.Results: Visual analog scale (VAS) assessment, pain localization, quality of life SF-36 form, and University of California at Los Angeles (UCLA) functional shoulder scoring were applied in both groups. Mean VAS score in group 1 was significantly higher than in group 2. Only the vitality measure mean score was not significantly different in SF-36 assessment; however, in group 2 physical function and mental health scale mean scores were higher and the pain scale mean score was lower than in group 1. The total UCLA score and UCLA subgroups of pain, function, active flexion angle and strength revealed a statistically significant difference between groups.Conclusions: Patients in whom an IMA retractor was not utilized during surgery exhibited better results in physical functions, emotional status, and shoulder pain in the postoperative period.
