However, their value in predicting coronary artery disease (CAD) has been little studied. We aimed to assess the relationship between these scores and the extent of coronary disease. MethodsWe analyzed 238 consecutive patients admitted for NSTE-ACS and undergoing a coronary angiogram during hospitalization. The severity of CAD was assessed using the SYNTAX score. Obstructive CAD was defined as ≥50% stenosis in the left main or ≥70% stenosis in other vessels. Severe CAD was defined as a SYNTAX score >32. The Pearson test was used to assess the correlation between scores. ResultsThe SYNTAX score was higher in patients at high risk (GRACE score: p<0.001 and TIMI score: p=0.001). Moreover, there was a significant positive correlation between the GRACE and SYNTAX scores (r=0.23, p<0.001) as well as between TIMI and SYNTAX (r=0.2, p=0.002). Both clinical scores can predict obstructive CAD moderately well (area under the curve [AUC] for GRACE score: 0.599, p=0.015; TIMI score: AUC 0.639, p=0.001) but not severe disease. A GRACE score of 120 and a TIMI score of 2 were predictive of obstructive CAD with, respectively, a sensitivity of 57% and 75.7% and a specificity of 61.8% and 47.9%. ConclusionThe GRACE and TIMI scores correlate moderately with the extent of coronary disease assessed by the SYNTAX score. They can predict obstructive CAD but not severe disease. ER -
