Abstract
Abstract
Background
The model for end-stage liver disease excluding international normalized ratio (MELD-XI) is a simple score for risk assessment. However, the prognostic role of MELD-XI and its additional value to current risk assessment in elderly patients with ST-segment elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI) is uncertain.
Methods
In all, 1029 elderly patients with STEMI undergoing PCI were consecutively included and classified into three groups according to the TIMI risk score: low-risk (≤ 3, n = 251); moderate-risk (4–6, n = 509); and high-risk (≥ 7, n = 269) groups. Multivariate analysis was performed to identify risk factors for adverse events.
Results
The overall in-hospital mortality was 5.3% and was significantly higher in the high-risk group (1.2% vs. 3.3% vs. 13.0%, p < 0.001). The optimal cut-off of the TIMI risk score and MELD-XI for in-hospital death was 7 and 13, respectively. MELD-XI was associated with in-hospital (adjusted odds ratio = 1.09, 95% CI = 1.04–1.14, p = 0.001) and one-year (adjusted hazard ratio = 1.05, 95% CI = 1.01–1.08, p = 0.005) mortality independently of the TIMI risk score. Combining TIMI risk score and MELD-XI exhibited better predictive power for in-hospital death than TIMI risk score (area under the curve [AUC] = 0.810 vs. 0.753, p = 0.008) or MELD-XI alone (AUC = 0.810 vs. 0.750, p = 0.018). Patients with TIMI risk score ≥ 7 and MELD-XI ≥ 13 had the worst prognosis.
Conclusion
MELD-XI could be considered as a risk-stratified tool for elderly patients with STEMI undergoing PCI. It had an additive prognostic value to TIMI risk score.
