This study was designed to determine the prognostic index which will best reflect short-term outcome of acute myocardial infarction (AMI) in Chinese patients. For this purpose, the predictive ability of 8 short term prognostic indices for AMI were compared in 340 patients, using receiver-operator characteristic curve (ROC) analysis. It was found that there was no statistically significant difference between the Norris and Dubois indices, which were the two best performing ones. The Dubois index had the advantage of simpler computation and of being based on clinical variables that are routinely measured in most hospital settings.
