What results prompted reevaluation of the recommendation for aspiration thrombectomy before primary PCI?
The results of three multicenter trials prompted reevaluation of the recommendation for aspiration thrombectomy before primary PCI. These trials were the INFUSE-AMI trial, which enrolled 452 patients with anterior STEMI due to proximal or mid-left anterior descending occlusion, the TASTE trial, which enrolled 7244 patients, and the TOTAL trial, which enrolled 10,732 patients. The results of these trials showed no significant differences between the group that received aspiration thrombectomy before primary PCI and the group that received primary PCI only with regard to death, reinfarction, stent thrombosis, target lesion revascularization, or a composite of major adverse cardiac events.
