The Value of the GRACE Score for Predicting the SYNTAX Score in Patients with Unstable Angina/Non-ST Elevation Myocardial Infarction
Highlights
- • There is a positive correlation between the GRACE score and angiographic SYNTAX score.
- • GRACE score could significantly predict the severity and extent of coronary artery stenosis.
- • GRACE score of 109 could predict SYNTAX score ≥ 23 with a sensitivity of 73.5%.
- • The high negative predictive value (94.0%) of GRACE score means it may help to predict normal coronary individuals or mild CAD patients.
Abstract
Background
In patients with unstable angina/non-ST-elevation myocardial infarction (UA/NSTEMI), Global Registry for Acute Coronary Events (GRACE) score is a valid tool for risk stratification. The Synergy between PCI with Taxus and Cardiac Surgery (SYNTAX) score is an angiographic scoring system to guide the decision-making between coronary artery bypass grafting (CABG) surgery and percutaneous coronary intervention (PCI). The aim of the present study was to assess the accuracy of the GRACE score in predicting the severity and extent of coronary artery stenosis by SYNTAX score.
