The GRACE risk score showed a significant positive correlation (r=0.66) with the angiographic severity of coronary artery disease assessed by the Gensini score in patients with non-ST-elevation acute coronary syndrome.

Does a higher GRACE risk score predict greater angiographic severity of coronary artery disease in patients with non-ST-elevation acute coronary syndrome?
The GRACE risk score has a significant positive correlation with the angiographic severity of coronary artery disease in patients with NSTE-ACS, suggesting it can help predict anatomical extension of CAD prior to angiography.

Background: Due to the wide spectrum of risk for death and recurrent events among patients with NSTE-ACS, management guidelines emphasise the importance of early risk stratification. In addition to prognostic assessment, predicting the anatomical extension of coronary artery disease is potentially useful for clinical decision. The aim of the study is to determine whether the GRACE risk score correlates with the angiographic extent and severity of coronary artery disease in patients with non ST-elevation ACS Methods: A total of 50 patients with non-ST-elevation acute coronary syndrome were enrolled to the study. Based on the GRACE risk score classification system, the patients were divided into low (140) risk groups. All patients underwent coronary angiography within five days after admission. The severity of the coronary artery disease was assessed by Gensini score. Relation between Grace score and Gensini score was evaluated. Results: Mean Gensini score were 12.20 ± 13.60, 34.52 ± 13.50 and 48.41 ± 14.56 in low group, intermediate group and high GRACE risk group respectively and the difference of mean Gensini score was statistically significant (p<0.001). A GRACE score of 135 was identified as the optimal cut-off to predict severe CAD (sensitivity = 82.4% and specificity = 75.8%). In our study correlation co-efficient between GRACE risk score and Gensini score was r=0.66 (p<0.001). Conclusion: The study demonstrates that the GRACE risk score has significant positive correlation with coronary artery stenosis in patients with non-ST-elevation acute coronary syndrome.

Rahman et al. (Mon,) conducted a cross-sectional in Non ST-elevation Acute Coronary Syndrome (n=50). GRACE risk score was evaluated on Correlation between GRACE risk score and Gensini score (r=0.66, p=<0.001). The GRACE risk score showed a significant positive correlation (r=0.66) with the angiographic severity of coronary artery disease assessed by the Gensini score in patients with non-ST-elevation acute coronary syndrome.
