Abstract
Background: Previous studies have shown that hepatic fibrosis indices and rates can be used to predict cardiovascular mortality and morbidity. Our aim with this study was to investigate the effect of aspartate aminotransferase/alanine aminotransferase (AST/ALT) ratio and fibrosis?4 (FIB?4) index calculated with ALT, AST, and platelet biomarkers, which are simple, fast, and relatively inexpensive and were used in previous studies to predict cardiovascular disease prognosis, on the prediction of postoperative morbidity and early mortality after mitral valve replacement (MVR) surgery. Methods: By scanning the hospital electronic health record system, 116 patients who underwent isolated MVR or MVR + tricuspid valve intervention were identified from 178 patients who underwent MVR with the standard sternotomy procedure between 2011 and 2021. The study was completed with 81 of these patients. Patients were divided into AST/ALT <2 (Group 1) and >2 (Group 2). In addition, the same patients were divided into FIB?4 index <3.25 (Group 3) and >3.25 (Group 4), and a total of four groups were formed. Results: The mean age of Group 2 was significantly higher than Group 1 (P = 0.049). In addition, the mean age of Group 4 was significantly higher than Group 3 (P = 0.003). Postoperative complications did not differ between Groups 1 and 2 (P > 0.05). While noninvasive mechanincal ventilation (NIMV) requirements did not differ between Groups 3 and 4 (P > 0.05), MV duration and intensive care unit stay were significantly longer in Group 4 (P < 0.05). Conclusion: The AST/ALT ratio, which has been shown to be a predictor of cardiovascular mortality in various studies, was not useful in predicting mortality and morbidity in our study. However, a high FIB?4 index, another hepatic fibrosis index, was found to be associated with increased perioperative bleeding, duration of mechanical ventilation, and cardiac intensive care unit stay, which are important criteria in the prediction of morbidity in cardiovascular surgery.
