AIM To assess fatigue severity in patients with rheumatoid arthritis (RA) using the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) scale and to examine its association with demographic, socioeconomic, clinical, and lifestyle-related factors. METHODS This cross-sectional observational study included 90 adults with RA. Fatigue was assessed using the FACIT-F scale, and disease activity was assessed using the Disease Activity Score in 28 joints (DAS28). Continuous variables were summarised as medians and interquartile ranges (IQRs). Associations were evaluated using Spearman correlation, Mann-Whitney U, Kruskal-Wallis, and robust linear regression analyses. RESULTS The median FACIT-F score was 37.0 [IQR 27.0 - 45.0], and 35.6% of patients had moderate-to-severe fatigue. FACIT-F correlated negatively with DAS28 (ρ = -0.381; p < 0.001). In multivariable robust regression, DAS28 remained associated with FACIT-F score after adjustment for age and disease duration (β = -3.54; 95% confidence interval -5.39 to -1.68; p < 0.001), whereas age and disease duration were not significant. FACIT-F scores differed by sex and employment status but not by treatment category. CONCLUSION Fatigue is a prevalent and clinically important symptom in RA. Higher disease activity was associated with greater fatigue severity, supporting comprehensive assessment of fatigue beyond inflammatory disease activity alone.

AIM To evaluate the prognostic value of the CHA2DS2-VASc score in relation to major adverse cardiovascular events (MACE) and cardiovascular mortality in patients with non-ST elevation myocardial infarction (NSTEMI), and to assess its association with clinical and echocardiographic characteristics. METHODS This prospective, observational, cohort study included 311 NSTEMI patients admitted to the Internal Medicine Clinic at the University Clinical Centre Tuzla between January 2023 and April 2024. The patients were stratified into intermediate-risk (score < 4) and high-risk (score ≥ 4) groups based on the CHA2DS2-VASc score at admission. Demographic, clinical, and echocardiographic data were collected, including electrocardiography (ECG) and transthoracic echocardiography. All patients were followed for 3 months (90 days) to assess the occurrence of MACE and cardiovascular mortality. RESULTS The patients in the high-risk group were older and had significantly lower left ventricular ejection fractions and larger left atrial diameters compared with the intermediate-risk group. During the 3-month follow-up, MACE occurred in 11.9% of high-risk and 3.9% of intermediate-risk patients; cardiovascular mortality was observed exclusively in the high-risk group (2.5%). A higher CHA2DS2-VASc score was significantly associated with cardiovascular mortality (p = 0.003), but not with overall MACE (p = 0.393). Moderate predictive accuracy for mortality (AUC = 0.64) and shorter event-free survival in the high-risk group (log-rank p = 0.005) were observed. CONCLUSION The CHA2DS2-VASc score showed potential as a simple and accessible tool for early identification of NSTEMI patients at risk of cardiovascular death. Its significant association with mortality supports its role as a supplementary risk stratification tool, although these findings require validation in larger, multicentre studies.

AIM To compare outcomes of elective open inguinal hernia repair under local anaesthesia (LA) and general anaesthesia (GA). METHODS This retrospective cohort included 833 adults treated in Tuzla during 2017-2025. The primary outcome was any early adverse outcome within 30 days. Secondary outcomes included analgesic requirement, chronic groin pain, discomfort, dissatisfaction, and recurrence. Logistic regression adjusted for age, American Society of Anesthesiologists physical status, hernia characteristics, and technique. Adjusted odds ratios (aORs) with 95% confidence intervals (CIs) were reported; Benjamini-Hochberg correction was applied to secondary outcomes. RESULTS The LA group included 425 patients and the GA group 408. Postoperative analgesia was required in 338 (79.5%) and 110 (27.0%) patients, respectively (p<0.001). An early adverse outcome occurred in 79 (18.6%) and 35 (8.6%) patients (aOR 2.08, 95% CI 1.31-3.30; p = 0.002), mainly because of more haematomas with LA, 54 (12.7%) versus 20 (4.9%) (p < 0.001). Chronic groin pain did not differ after adjustment (aOR 1.26, 95% CI 0.81-1.96; p = 0.310). Dissatisfaction was higher with LA, 85 (20.8%) versus 40 (10.1%) (aOR 1.95, 95% CI 1.27-2.99; p = 0.002). Eight recurrences were recorded. Median follow-up was 14 months (interquartile range 12-18 months). CONCLUSION LA was associated with more early adverse outcomes and dissatisfaction than GA. Chronic pain did not differ after adjustment, and recurrence was similar. Selection bias and residual confounding should be considered.

AIM To determine the prevalence of irritable bowel syndrome (IBS)-related symptoms and associated factors among medical students in Bosnia and Herzegovina. METHODS This cross-sectional online survey included 176 medical students from the universities of Sarajevo and Zenica between November 2022 and December 2023. IBS-related symptoms were assessed using the Serbian-language Rome III questionnaire, and test anxiety using the Westside Test Anxiety Scale. Categorical variables were compared using Pearson's χ² test. RESULTS Eighty-four students (47.7%) met the symptom-based Rome III criteria. The IBS-related symptoms group included 75 females (89.3%) compared with 54 (58.7%) in the comparison group (p<0.001). Sweets consumption at least four times weekly was reported by 53 (63.1%) and 45 (48.9%) students, respectively (p = 0.021). Test-anxiety distributions differed between groups (p < 0.001); extremely high anxiety was reported by 12 (14.3%) students with IBS-related symptoms and one (1.1%) without symptoms. Other sociodemographic and lifestyle characteristics were not associated with IBS-related symptoms. CONCLUSION IBS-related symptoms were frequent in this medical-student sample and were associated with female sex, frequent sweets consumption, and test anxiety. The cross-sectional, self-reported design precludes causal interpretation and clinical confirmation of IBS.

Background/Objectives: Early risk stratification remains challenging in patients with non-ST-segment elevation myocardial infarction (NSTEMI). The present study evaluated the prognostic value of 24 h high-sensitivity cardiac troponin I (hs-Troponin I) and assessed whether combining biomarkers and echocardiographic parameters improves short-term risk prediction. Methods: This prospective observational cohort study included 170 consecutive adult patients with confirmed NSTEMI who were admitted to a Medical Intensive Care Unit and prospectively enrolled between February 2022 and January 2023. Clinical, routine biochemical, inflammatory, hematological, lipid, and echocardiographic data were collected during index hospitalization. High-sensitivity cardiac troponin I was measured at admission and again 24 h after hospitalization, with the 24 h value used as the principal marker of myocardial injury in the prediction analyses. The primary endpoint was major adverse cardiovascular events (MACEs), defined as cardiovascular death, recurrent myocardial infarction, ischemic stroke, urgent coronary revascularization, or hospitalization for worsening heart failure, within 3 months. Multivariable logistic regression, Cox regression, sequential prediction modeling, and internal bootstrap validation were performed. Results: MACEs occurred in 88 patients (51.8%). Twenty-four-hour hs-Troponin I, but not admission hs-Troponin I, was independently associated with MACEs (OR 1.57, 95% CI 1.09–2.26; p = 0.015) and a shorter time to the first MACE event (HR 1.38, 95% CI 1.07–1.78; p = 0.012). Lower left ventricular ejection fraction (LVEF) was also independently associated with adverse outcomes. The addition of 24 h hs-Troponin I, LVEF, and C-reactive protein improved discrimination from an AUC of 0.665 to 0.759 (optimism-corrected AUC, 0.717), with corresponding improvements in reclassification. A simplified multimarker score was independently associated with event-free survival (HR 2.36, 95% CI 1.53–3.64; p < 0.001). Conclusions: In patients admitted to a medical intensive care unit with NSTEMI, the integration of 24 h hs-Troponin I, LVEF, and C-reactive protein improved short-term risk prediction beyond that of clinical variables alone. A practical multimarker model based on routinely available parameters identified patients at increased risk of adverse cardiovascular outcomes during early follow-up.

AIM To determine the prevalence and microbiological profile of ventilator-associated pneumonia (VAP) in mechanically ventilated patients and to assess clinical and laboratory parameters associated with its development, with emphasis on C-reactive protein (CRP) levels and duration of mechanical ventilation. METHODS This single-centre prospective observational cohort study included 118 adult patients who required invasive mechanical ventilation for more than 48 hours in the intensive care unit of the University Clinical Centre Tuzla. Patients were classified into VAP and non-VAP groups. Demographic, clinical, laboratory, and microbiological data were collected, and in-hospital outcomes were recorded. Statistical analysis included between-group comparisons, univariate logistic regression, and receiver operating characteristic (ROC) curve analysis. RESULTS VAP was diagnosed in 41 patients (34.7%). Gram-negative pathogens predominated (≈ 85%), with Acinetobacter baumannii identified most frequently (43.9%), followed by Pseudomonas aeruginosa and Klebsiella pneumoniae. Patients with VAP had significantly longer durations of mechanical ventilation (12.5 vs. 7.3 days, p < 0.001) and hospitalisation (19.6 vs. 12.2 days, p < 0.001), as well as higher CRP levels (178.2 vs. 126.4 mg/L, p < 0.001). Reintubation, elevated CRP, leukocytosis, hypercapnia, and prolonged mechanical ventilation were associated with VAP. CRP demonstrated good-to-moderate discriminative ability for VAP (AUC = 0.83). CONCLUSION VAP remains a common and clinically significant complication in mechanically ventilated patients. Elevated CRP levels and prolonged mechanical ventilation may support early clinical suspicion using routinely available parameters.

AIM To analyse patient admission patterns, clinical outcomes, and organisational workload in a medical intensive care unit (ICU), with emphasis on early mortality and post-pandemic changes in healthcare demand. METHODS This retrospective, observational, single-centre cohort study included all adult patients admitted to the medical ICU of the Clinic for Internal Medicine at the University Clinical Centre Tuzla between January 1, 2018, and December 31, 2025. Aggregated data were obtained from the hospital information system and internal ICU records. Analysed variables included annual admission volume, admission sources, discharge outcomes, in-hospital and early mortality (within 24-72 hours after ICU admission), estimated length of stay, invasive procedures, and patient age. Temporal trends were assessed across pre-pandemic (2018-2019), pandemic (2020-2021), and post-pandemic (2022-2025) periods. RESULTS A total of 9,342 ICU hospitalisations were analysed. Admissions remained relatively stable through 2020, declined in 2021, reached their lowest level in 2022, and then increased markedly from 2023 onward. Admissions per bed rose from 67.5 in 2022 to 108.6 in 2025, while the estimated mean ICU length of stay decreased from 5.4 to 3.4 days. Overall, in-hospital mortality was approximately 22%, with 75-80% of deaths occurring between 24 and 72 hours from admission. The patient population was predominantly elderly, with a mean age of approximately 70 years. CONCLUSION Medical ICU services operated under increasing organisational strain, reflected by rising admission volume, higher admissions per bed, and reduced estimated length of stay despite fixed bed capacity. Persistently high early mortality remained a prominent feature of this population.

BACKGROUND Acute hyperglycemia is frequently observed in patients presenting with acute coronary syndromes and is considered a marker of metabolic and neurohormonal stress. However, its prognostic significance relative to chronic glycemic status remains incompletely understood, particularly in patients with non-ST-segment elevation myocardial infarction (NSTEMI). Glycated hemoglobin (HbA1c) reflects long-term glycemic control but may not adequately capture acute metabolic derangements occurring during myocardial ischemia. Stress hyperglycemia reflects a transient metabolic response to acute illness mediated by counter-regulatory hormones, systemic inflammation, and increased hepatic gluconeogenesis, and does not necessarily indicate pre-existing insulin resistance or chronic dysglycemia. Recent studies suggest that stress-related hyperglycemia indices may better reflect short-term risk, yet comparative data in NSTEMI populations remain limited. AIM To determine whether admission stress hyperglycemia indices are associated with early mortality in patients with non-ST elevation myocardial infarction. METHODS This prospective, single-center observational study consecutively enrolled 171 patients admitted with confirmed NSTEMI. Stress hyperglycemia was assessed using the stress hyperglycemia ratio (SHR) and the admission glucose-to-chronic glycemia ratio (ACGR), calculated from admission plasma glucose and HbA1c values obtained at hospital presentation. Patients were categorized according to established HbA1c thresholds. Clinical, laboratory, and echocardiographic data were systematically collected. All patients were followed for three months after discharge. The primary endpoint was the occurrence of major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, or urgent coronary revascularization. The secondary endpoint was all-cause mortality. Discriminatory performance was evaluated using receiver operating characteristic (ROC) curve analysis. Multivariable logistic regression models were constructed to assess the independent and incremental prognostic value of stress hyperglycemia indices before and after adjustment for established clinical and echocardiographic predictors. RESULTS During the three-month follow-up period, 88 MACE and 25 deaths were recorded. HbA1c categories were not significantly associated with all-cause mortality or MACE. In contrast, admission glucose levels, SHR, and ACGR were significantly higher in non-survivors than in survivors. No significant differences in HbA1c were observed between outcome groups. Stress hyperglycemia indices demonstrated modest discriminatory ability for predicting mortality and showed greater discrimination than HbA1c in ROC analyses. In multivariable models, both SHR and ACGR remained independently associated with early mortality after adjustment for demographic, clinical, and echocardiographic variables, whereas no independent association with the composite MACE endpoint was observed. ROC-derived thresholds used for survival analyses were exploratory and have not been externally validated. CONCLUSION In patients with NSTEMI, stress hyperglycemia indices assessed at hospital admission are independently associated with early mortality, whereas chronic glycemic status shows limited prognostic relevance. These indices appear to reflect acute systemic stress and metabolic instability and may provide clinically useful information for early risk stratification during the initial phase of hospitalization, particularly when comprehensive echocardiographic assessment is not yet available.

Background/Objectives: Cardiorenal syndrome type 2 (CRS-2) is characterized by progressive renal dysfunction caused by chronic heart failure (HF) and is associated with increased morbidity and mortality. However, the prognostic value of renal biomarkers in patients with CRS-2 hospitalized for decompensated HF remains unclear. Methods: This prospective observational cohort study included 200 consecutive patients hospitalized for decompensated HF in the Intensive Care Unit of the Clinic for Internal Medicine at the University Clinical Centre Tuzla between April and October 2025. CRS-2 was defined as chronic HF with chronic kidney disease persisting for ≥3 months before admission according to KDIGO criteria. Patients were followed for three months. The primary composite outcome was all-cause mortality or initiation of renal replacement therapy. Results: CRS-2 was identified in 130 patients (65.0%) and was associated with higher in-hospital mortality (32.3% vs. 11.4%, p = 0.002) and three-month mortality (44.6% vs. 21.4%, p = 0.002). Within the CRS-2 subgroup, patients who experienced the primary composite outcome had higher admission levels of cystatin C and urinary albumin-to-creatinine ratio (UACR) and lower estimated glomerular filtration rate (eGFR). ROC analysis demonstrated moderate discriminative ability of cystatin C (AUC 0.739) and UACR (AUC 0.733). In Cox regression analysis, cystatin C (HR 1.534, 95% CI 1.263–1.863, p < 0.001) and UACR (HR 1.003, 95% CI 1.001–1.006, p = 0.001) were significantly associated with the primary composite outcome. Conclusions: Renal dysfunction markers, particularly cystatin C and albuminuria, are associated with early adverse outcomes in CRS-2 patients hospitalized for decompensated HF. Routine assessment of these biomarkers may provide additional prognostic information and support risk assessment in this high-risk population.

Background Appropriate oral hygiene practices established in early childhood are essential for preventing dental caries. Parental awareness and supervision during the early school years play a key role in the development of effective daily oral hygiene habits. However, data on oral hygiene practices and the use of preventive dental products among children at school entry remain limited in many primary healthcare settings. Materials and methods This cross-sectional study included 307 six-year-old children who attended routine school-entry dental examinations at the Department of Dentistry, Public Health Institution "Health Center" Živinice, Bosnia and Herzegovina, between September 2022 and September 2024. Parents completed a structured questionnaire on the timing of the child’s first dental visit, initiation of toothbrushing, caregiver involvement in daily oral hygiene, and use of mechanical and chemical oral hygiene products. Categorical variables were summarized using descriptive statistics, and differences in questionnaire responses were analyzed using the Pearson Chi-square (χ²) test, with a significance level of p < 0.05. Results Delayed initiation of the first dental visit and toothbrushing were commonly reported. Only a minority of children attended their first dental visit following eruption of the first tooth, while most began brushing after eruption of several primary teeth. Parental supervision of oral hygiene was inconsistent, and independent brushing from the beginning was reported in a subset of children. Although regular toothbrush and toothpaste use was nearly universal, the use of adjunctive preventive products was limited, and more than half of parents were unaware of the fluoride content of their children's toothpaste. Conclusion Oral hygiene practices among six-year-old children appear suboptimal, with delayed initiation of preventive care and limited parental awareness of fluoride use. Educational interventions aimed at improving caregiver knowledge and supervision of children’s oral hygiene practices may support the development of more effective preventive behaviors at school entry.

Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare systemic vasculitis characterized by asthma, eosinophilia, and multisystem involvement. Renal manifestations are relatively uncommon but may be severe and rapidly progressive, and fatal hemorrhage from arteriovenous fistulas (AVFs) represents an uncommon yet catastrophic complication in patients with advanced kidney disease. We report a case of a 70-year-old man with long-standing asthma, chronic rhinosinusitis with nasal polyposis, marked eosinophilia, and progressive renal failure. After years of fragmented clinical manifestations, a clinical diagnosis of EGPA was considered based on clinical, laboratory, and immunological findings, supported by fulfillment of the 2022 American College of Rheumatology/European Alliance of Associations for Rheumatology (ACR/EULAR) classification criteria in the absence of histopathological confirmation, in the setting of rapidly progressive renal dysfunction. Induction immunosuppressive therapy with high-dose corticosteroids and cyclophosphamide was initiated. Due to advanced chronic kidney disease and the anticipated need for renal replacement therapy, a left radiocephalic AVF was constructed. Seventeen days later, the patient experienced spontaneous fistula rupture at home, resulting in massive hemorrhage, refractory hemorrhagic shock, and death. This case illustrates the consequences of delayed EGPA diagnosis and highlights the possibility of fatal vascular access complications in the setting of active systemic vasculitis, underscoring the importance of careful timing of invasive procedures, heightened clinical vigilance, and structured patient education when planning vascular access in patients with active inflammatory disease.

AIM Vaccine hesitancy challenges global public health, with parental attitudes significantly impacting childhood immunization. This study examined parental perceptions of vaccine safety, effectiveness, and decision-making factors in Bosnia and Herzegovina. METHODS A cross-sectional survey was conducted in March 2025 with 233 parents at a Primary Healthcare Center in Gračanica. A structured questionnaire based on the Parent Attitude about Childhood Vaccines (PACV) assessed sociodemographic data, vaccination experiences, information sources, and attitudes toward vaccines using a Likert scale. RESULTS Among 233 participants, 195 (83.7%) fully vaccinated their children, 30 (12.9%) practiced selective vaccination, and eight (3.4%) refused all vaccines. Vaccine hesitancy was significantly associated with lower education, (26.3% vs. 5.1%; p<0.001), rural residence (76.3% vs. 48.2%; p=0.002), and having three or more children (34.2% vs. 12.3%; p=0.01). Trust in healthcare professionals strongly influenced behavior, with 178 (91.3%) of parents who fully trusted doctors adhering to the immunization schedule. Concerns about autism were reported by 14 (36.8%) of hesitant parents and were significantly associated with delayed or refused vaccination (p<0.001). CONCLUSION Although overall confidence was high, vaccine hesitancy persisted due to perceived risks. Strengthening healthcare communication and addressing misinformation, particularly autism concerns, may help improve vaccine uptake.

AIM To identify predictors of all-cause mortality and 6-month rehospitalisation in patients with hypertensive crisis, focusing on inflammatory indices, metabolic markers measured at admission, and antihypertensive treatment profiles. METHODS This prospective observational study included 210 adult patients with hypertensive crisis. Demographic, clinical, and therapeutic data were collected, including data on comorbidities, antihypertensive drug use, and treatment adherence. Laboratory parameters obtained at admission included neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation index (SII), pan-immune-inflammation value (PIV), homocysteine, and uric acid. Patients were followed for 12 months. Multivariate logistic regression and receiver operating characteristic (ROC) curve analyses were conducted to identify independent predictors. RESULTS Mortality occurred in 10.9% of patients, and 27.1% were rehospitalised within 6 months. Deceased patients exhibited significantly higher levels of PLR (p=0.0329), SII (p=0.0355), homocysteine (p=0.0488), and uric acid (p=0.021). In multivariate analysis, homocysteine (OR=3.55; p<0.001), uric acid (OR=1.03; p=0.007), PLR (OR=1.04; p=0.047), and SII (OR=1.01; p=0.030) remained independently associated with mortality. Chronic kidney disease (OR=2.15, p=0.012) and poor treatment adherence (OR=1.92; p=0.017) were also significant predictors. ROC analysis demonstrated moderate discriminative power, with AUC values of 0.68 for PLR, 0.66 for SII, 0.65 for homocysteine, and 0.63 for uric acid. CONCLUSION Elevated inflammatory indices and metabolic markers, particularly homocysteine and uric acid, were independently associated with increased mortality risk. Additionally, chronic kidney disease and suboptimal adherence to antihypertensive therapy significantly contributed to adverse outcomes. These findings underscore the importance of comprehensive risk assessment and personalised management in this high-risk population.

AIM To examine the association between metabolic parameters and novel cardiometabolic indices with the coronary artery calcium score (CACS). METHODS This retrospective cross-sectional study included 130 patients who underwent coronary computed tomography angiography (CCTA) at the Radiology Clinic of the Clinical Centre of the University of Sarajevo between January and June 2024. Patients were classified into two groups: those with CACS ≤100 and those with CACS >100. Platelet count, mean platelet volume (MPV), estimated glomerular filtration rate (eGFR), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides (TG), uric acid (UA), and novel cardiometabolic indices, including Castelli risk index I and II (CRI-I and CRI-II), non-high-density lipoprotein cholesterol (non-HDL-C), were compared between the groups. RESULTS Patients with CACS >100 had significantly higher MPV, TC, LDL-C, UA, non-HDL-C, CRI-I, CRI-II, and the UA/eGFR ratio. Older age, increased platelet activity, dyslipidemia, hyperuricemia, and the higher UA/eGFR ratio correlated positively with CACS, whereas eGFR correlated negatively. In multivariate regression analysis, the UA/eGFR ratio emerged as an independent predictor of higher CACS (OR = 2.37; 95% CI 1.18–4.78; p=0.017). CONCLUSION Elevated UA levels and adverse cardiometabolic indices are associated with greater coronary artery calcification. The UA/eGFR ratio independently predicts higher CACS, highlighting its potential prognostic value.

Background: Inflammation-driven mechanisms play a central role in adverse outcomes after non-ST-elevation myocardial infarction (NSTEMI), yet simple, widely available biomarkers for early risk stratification remain insufficiently defined. Hemogram-derived indices and iron-related inflammatory markers may provide complementary prognostic information. Objective: To evaluate the prognostic significance of the mean platelet volume-to-monocyte ratio (MMR) and serum ferritin in predicting major adverse cardiovascular events (MACE) in patients with NSTEMI, and to assess the association of angiotensin-converting enzyme (ACE) inhibitor therapy with clinical outcomes. Methods: This prospective cohort study included 170 consecutive NSTEMI patients admitted to the University Clinical Center Tuzla between February 2022 and January 2023. All patients received dual antiplatelet therapy and high-intensity statins. The baseline evaluation included a complete blood count, serum ferritin, and C-reactive protein. MMR was calculated as the ratio of mean platelet volume to absolute monocyte count. Patients were followed for 12 months for the occurrence of MACE, defined as cardiovascular death, non-fatal myocardial infarction, urgent revascularization, stroke, or hospitalization for heart failure. Results: During follow-up, 103 patients (60.6%) experienced MACE. Admission MMR (18.1 ± 11.7 vs 13.2 ± 5.5; P = 0.003) and ferritin levels (284 ± 396 vs 152 ± 109 µg/L; P = 0.001) were significantly higher in patients with events. In multivariable analysis, both MMR (odds ratio [OR] 1.06, 95% confidence interval [CI] 1.02-1.11; P = 0.008) and ferritin (OR 1.28 per 100 µg/L, 95% CI 1.10-1.55; P = 0.003) independently predicted MACE, while ACE inhibitor therapy was associated with a lower risk (OR 0.24, 95% CI 0.08-0.70; P = 0.01). The combined model demonstrated good discriminative performance (AUC 0.72; 95% CI 0.64-0.80). Conclusion and Relevance: Elevated admission MMR and ferritin were independently associated with a higher 1-year risk of MACE in patients with NSTEMI. ACE inhibitor therapy was associated with improved outcomes, although causality cannot be inferred. These findings suggest that readily available inflammatory biomarkers may complement established clinical parameters for early risk stratification and support continued guideline-directed pharmacotherapy in NSTEMI.
