Abstract
Aim: This retrospective, multi-center study evaluates the relationships between novel liver function scoring systems - Albumin-Bilirubin (ALBI) score, EZ-ALBI, PALBI, and MELD-XI - and outcomes in patients undergoing transcatheter aortic valve implantation (TAVI). Feature importance was assessed with SHAP-values via the XGBoost-algorithm.
Results: The ALBI score exhibited the strongest association with 30-day mortality after TAVI (AUC = 0.723, p < 0.001), outperforming other scores in this regard and consistently demonstrating predictive power across various subgroup populations. Higher 30-day mortality rates were observed in the higher tertiles of the ALBI score compared to the lower tertiles (log-rank p-value = 0.004). The ALBI-based nomogram (C-index = 0.81, 95% CI:0.73-0.86, p = 0 < 001) demonstrated superior predictive power for 30-day mortality post-TAVI compared to the STS (C-index = 0.71, 95% CI :0.64-0.77, p = 0 < 001). In addition, the nomogram showed a significant improvement in reclassification (69.3%, p < 0.001) and a stronger discrimination 15.2%, p < 0.001) compared to the STS. It integrates nine variables, first ALBI score (SHAP:1.165), including NYHA class (0.594), body mass index (0.510), glomerular filtration rate, creatinine, hemoglobin, gender, predilatation requirement, presence of chronic kidney disease, and providing a comprehensive risk assessment tool.
Conclusion: This study exhibits the significance of liver dysfunction with AS patients and suggests incorporating liver function parameters in pre-operative risk assessments for better clinical outcomes in TAVI procedures.
期刊介绍:
Biomarkers are physical, functional or biochemical indicators of physiological or disease processes. These key indicators can provide vital information in determining disease prognosis, in predicting of response to therapies, adverse events and drug interactions, and in establishing baseline risk. The explosion of interest in biomarker research is driving the development of new predictive, diagnostic and prognostic products in modern medical practice, and biomarkers are also playing an increasingly important role in the discovery and development of new drugs. For the full utility of biomarkers to be realized, we require greater understanding of disease mechanisms, and the interplay between disease mechanisms, therapeutic interventions and the proposed biomarkers. However, in attempting to evaluate the pros and cons of biomarkers systematically, we are moving into new, challenging territory.
Biomarkers in Medicine (ISSN 1752-0363) is a peer-reviewed, rapid publication journal delivering commentary and analysis on the advances in our understanding of biomarkers and their potential and actual applications in medicine. The journal facilitates translation of our research knowledge into the clinic to increase the effectiveness of medical practice.
As the scientific rationale and regulatory acceptance for biomarkers in medicine and in drug development become more fully established, Biomarkers in Medicine provides the platform for all players in this increasingly vital area to communicate and debate all issues relating to the potential utility and applications.
Each issue includes a diversity of content to provide rounded coverage for the research professional. Articles include Guest Editorials, Interviews, Reviews, Research Articles, Perspectives, Priority Paper Evaluations, Special Reports, Case Reports, Conference Reports and Company Profiles. Review coverage is divided into themed sections according to area of therapeutic utility with some issues including themed sections on an area of topical interest.
Biomarkers in Medicine provides a platform for commentary and debate for all professionals with an interest in the identification of biomarkers, elucidation of their role and formalization and approval of their application in modern medicine. The audience for Biomarkers in Medicine includes academic and industrial researchers, clinicians, pathologists, clinical chemists and regulatory professionals.
