摘要
This study analyzed 255,256 patients who had acute myocardial infarction and were enrolled in the National Registry of Myocardial Infarction 2, 3, and 4(1994 to 2002). The objective was to determine in-hospital mortality rate among patients who had ST-segment depression on the initial electrocardiogram. Patients who had ST-segment depression had an in-hospital mortality rate(15.8%) similar to that of patients who had ST segment elevation or left bundle branch block(15.5%). After adjusting for observed differences, ST-segment depression was associated with only a slightly lower odds ratio(0.91) of mortality compared with ST-segment elevation or left bundle branch block.
