Abstract

This randomized trial compared rheolytic thrombectomy before direct infarct artery stenting with direct infarct artery stenting alone in 100 patients with a first acute myocardial infarction (AMI). The primary end point of the study was early ST-segment elevation resolution, and the secondary end points were corrected Thrombolysis In Myocardial Infarction (TIMI) frame count, infarct size, and 1-month clinical outcome. The primary end point rates were 90% in the thrombectomy group and 72% in the placebo group (p = 0.022). Randomization to thrombectomy was independently related to the primary end point (odds ratio 3.56, p = 0.032). The corrected Thrombolysis In Myocaridal Infarctions (TIMI) frame count was lower in the thrombectomy group (18.2 +/- 7.7 vs 22.5 +/- 11.0, p = 0.032), and infarct size was smaller in the thrombectomy group (13.0 +/- 11.6% vs 21.2 +/- 18.0%, p = 0.010). At 1 month, there were no major adverse cardiac events. Rheolytic thrombectomy before routine direct infarct-related artery (IRA) stenting is highly feasible and provides more effective myocardial reperfusion in patients undergoing percutaneous coronary intervention for AMI.
