Background/Objectives: Multi-organ failure (MOF) often complicates advanced heart failure (HF), contributing to a poor prognosis. The Model of End-Stage Liver Disease 3.0 (MELD-3.0) scale incorporates liver and kidney function parameters. This study aims to evaluate the prognostic significance of the MELD-3.0 score in patients with advanced HF who have undergone heart transplantation (HTx). Methods: The MELD-3.0 score was computed using the average values of the international normalized ratio and bilirubin, creatinine, sodium, and albumin levels during a hospital stay following HTx. The average MELD-3.0 scores from the period of 1 month preceding HTx and 1 week after HTx were analyzed. The primary endpoint of the study was the 6-month total mortality, and the secondary endpoint was ICU hospitalization time after HTx. Results: The analysis included 106 patients undergoing HTx, with a median age of 53 years (44–63), 81% of whom were male. Within 6 months post-HTx, 17 patients (16%) died; those patients had a higher 1-week post-HTx MELD-3.0 score of 18.3 (14.5–22.7) in comparison to survivors, whose average score was 13.9 (9.5–16.4), p < 0.01. There was no difference in MELD 3.0 score in the pre-HTx period: 16.6 (11.4–17.8) vs. 12.3 (8.6–17.1), p = 0.36. The post-HTx MELD-3.0 score independently predicted death: RR 1.17 (95% CI 1.05–1.30), p < 0.01. A Receiver Operating Characteristic (ROC) determined the cut-off value of the MELD-3.0 score as 17.3 (AUC = 0.83; sensitivity—67%; specificity—86%). Survivors with scores above this value had a longer ICU hospitalization time: 7 (5.0–11.0) vs. 12 (8–20) days (p = 0.01). Conclusions: The post-HTx MELD-3.0 score serves as an independent predictor of an unfavorable prognosis in patients with advanced HF undergoing HTx. The evaluation of MELD-3.0 scores provides additional prognostic information in this population.

Dressler's syndrome, a rare complication of myocardial infarction, is a form of secondary pericarditis that typically develops within one to six weeks following the infarction. In this report, we present a case of a 68-year-old woman who was diagnosed with Dressler’s syndrome after nine weeks from acute coronary syndrome. The patient first presented with an ill-tolerated episode of atrial fibrillation. Based on clinical, laboratory, and imaging findings, accompanied by a history of respiratory tract infections, an infection of an unknown origin was initially suspected. Lack of response to the applied treatment prompted the suspicion of Dressler's syndrome. This was followed by a cardiac MRI, which showed features of pericarditis. The patient responded well to a seven-day treatment with ibuprofen and was discharged home in good general condition.

Background/Objectives: Patients with advanced heart failure (HF) often suffer from impaired kidney function. Based on the pathophysiology of types I and II of cardiorenal syndrome, heart transplantation (Htx) may restore renal function. The aim of this study was to identify predictors of improvement in kidney function after HTx. Methods: Htx patients from a tertiary hospital were retrospectively divided into three groups—improvement (n = 24), deterioration (n = 31) and no significant change in eGFR (n = 45)—based on changes in their mean estimated glomerular filtration rate (eGFR) within the first three postoperative months, compared to the last three preoperative months. The threshold for eGFR improvement was defined as a ≥20% increase, while deterioration was defined as a ≥20% decrease. The no significant change group was defined as any change falling between these two values. Results: The median age of analyzed cohort was 54 (45–63) years, and 82% were male. Preoperatively, the improvement group was more frequently treated with inotropes or vasopressors and had significantly higher blood urea and total bilirubin levels before Htx. In the multivariate analysis, total bilirubin before Htx (OR 1.66; 95% CI; 1.24–2.69; p = 0.002) and no need for RRT early after Htx (OR 0.46; 95% CI 0.24–0.88; p = 0.02) were independent predictors of improved kidney function in the first three months after HTx. Conclusions: The improvement in renal function after HTx is uncommon. It could be expected in patients suffering from more severe forms of HF, with impaired kidney and liver function but who did not need RRT after the surgery.
