ABSTRACT
AIM: To validate the global registry of acute coronary events (GRACE) score in acute coronary syndromes (ACS) patients and study its angiographic correlation. METHODS AND RESULTS: Two-hundred and thirty-five ACS patients were studied for the combined endpoint of all-cause in-hospital mortality and non-fatal infarction/reinfarction. We tested the predictive accuracy of the composite GRACE score using the receiver operating characteristics (ROC) curve. Lower systolic blood pressure (SBP) (odds ratio [OR] 7.93, P=0.005), ST-segment deviation (OR 7.79, P=0.02) and cardiac biomarker positivity (OR > 6.52, P=0.01) were significantly associated with events. Serum creatinine > 1.4 mg/dL showed a trend towards statistical significance (OR 4.14, P=0.05), whereas age > 50 years (OR 3.62, P=not significant [NS]) and Killips class 4 (OR 2.71, P=NS) showed good association. The best value for predicting events was a GRACE score of > 217 and these patients were more likely to have double/triple vessel disease (P = 0.0009). The C statistic for the GRACE score was 0.75. CONCLUSION: Higher GRACE score predicts in-hospital events and more severe angiographic coronary artery disease (CAD).

One of the complications of prosthetic valve thrombosis (PVT) is systemic thromboembolism. We are reporting the occurrence of coronary artery embolism presenting as acute ST elevation myocardial infarction, 15 years after mitral valve replacement in a 30 year old female, with no clinical evidence of PVT.
