The Fibrosis-5 Index Predicts Major Adverse Cardiovascular Events in Patients With ST-Segment Elevation Myocardial Infarction Undergoing Percutaneous Coronary Intervention

This study aimed to evaluate the fibrosis-5 (FIB-5) index as a marker of liver fibrosis for major adverse cardiovascular events (MACE) in patients with ST-segment elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI). A total of 406 STEMI patients were enrolled in the study. Over an average follow-up of 27 months, 143 of the patients developed MACE. The patients were subgrouped into tertiles based on the FIB-5 index and Kaplan-Meier survival (MACE-free) curves were plotted, showing statistically significant differences (log-rank test, < .001). In the adjusted Cox regression model, the hazard ratio (HR) of MACE was 1.95 (95% CI 1.21-3.13; = .006) in tertile 3 and 0.98 (95% CI 0.97-1.00; = .013) for per unit increase in the FIB-5 index. The area under the curve (AUC) of the FIB-5 index predicting the occurrence of MACE in STEMI patients after PCI was 0.645 (95% CI 0.590-0.701; < .001). Low FIB-5 may be a useful predictor of MACE in STEMI patients undergoing PCI.
