The APSAC interventional mortality study (AIMS) trial: mortality data

The anistreplase (anisoylated plasminogen streptokinase activator complex or APSAC) intervention mortality study was designed as a double-blind, placebo-controlled study to test the effectiveness of anistreplase, 30 U administered intravenously within the first 6 hours of acute myocardial infarction. The primary endpoint of the study was mortality of all causes at 30 days and 1 year. Within 30 days, there were 77 deaths with placebo (17.8%) and 40 deaths (6.5%) with anistreplase, an odds reduction of 50.5% (p = 0.0006). By the end of one year, there had been a total of 113 deaths (17.8%) with placebo and 69 deaths (11.1%) with anistreplase, an odds reduction of 42.7% (p = 0.0007).
