Long-term forecasting and comparison of mortality in the Evaluation of the Xience Everolimus Eluting Stent vs. Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization (EXCEL) trial: prospective validation of the SYNTAX Score II [1]
The investigators of this project aimed to validate the SYNTAX Score II. This is a risk prediction tool that combines clinical characteristics and the original anatomical SYNTAX score in order to make 4 year mortality predictions with PCI or CABG in patients with unprotected left main disease (ULMCA) and an original SYNTAX score <33). They found that the SYNTAX Score II predicts an equipoise for long-term mortality between CABG and PCI in these patients.
