  • Title: Angiographic assessment of patency and reocclusion: preliminary results of the Dutch APSAC Reocclusion Multicenter Study (ARMS).

    Abstract:
    The main objective of the ARMS (APSAC Reocclusion Multicenter Study) trial was to obtain patency and reocclusion data. In an open multicenter study, a total of 156 patients were treated with 30 U of anistreplase or anisoylated plasminogen streptokinase activator complex (APSAC) within 4 h after onset of pain. Patency of the infarct-related vessel was assessed by coronary angiography performed 90 minutes after anistreplase administration. In those patients with a patent infarct-related vessel at 90 min, repeat coronary angiography was performed at 24 h to assess the reocclusion rate. Two independent cardiologists evaluated the angiograms and scored the coronary artery perfusion of the infarct-related vessel. The preliminary data of the first 148 patients indicate that the patency rate at 90 min was 73-75% and the reocclusion rate at 24 h was 4%. This patency rate corresponds with previous studies. The low reocclusion rate is noteworthy and probably reflects the prolonged action of anistreplase.
