Objective
In patients with non-ST elevation acute coronary syndrome (NSTE-ACS), identification of patients with high risk coronary anatomy (HRCA) who most likely to require CABG is crucial. The SYNTAX score (SXscore) is an angiographic grading tool designed to determine the complexity of coronary artery disease. It appears that CABG offers significantly better outcomes in patients with SXscore ≥ 33 which shows a very HRCA. We sought to assess the accuracy of the GRACE score in predicting HRCA in terms of SXscore in patients with NSTE-ACS.
Methods
Patients admitted to our coronary unit with a diagnosis of NSTE-ACS and undergoing coronary angiography during hospitalization were recruited to this study. Patients were categorized into two groups based on SXscore as HRCA (SXscore ≥33) and low risk coronary anatomy (LRCA, SXscore <33). Cut-off level of GRACE score for HRCA was established by receiver operator characteristic (ROC) analysis.
