Accuracy of the TIMI and GRACE scores in predicting coronary disease in patients with non-ST-elevation acute coronary syndrome

Introduction: The GRACE and TIMI scores have been well validated for assessment of prognosis in non-ST-elevation acute coronary syndrome (NSTE-ACS). 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. Methods: We 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. Results: The SYNTAX score was higher in patients at high risk (GRACE score: p32. O teste Pearson foi usado para avaliar a correlação entre os scores. Resultados: O valor do score Syntax foi superior nos doentes de alto risco (escore GRACE: p
