FilterWire-Ex in Primary PCI 106 patients with acute MI undergoing primary PCI Matched Case-Control Study • FilterWire-Ex (FW) • A distal embolic protection device • Successfully positioned in 89% of patients without complication • (n = 53) • Matched Control • Matched for infarct-related artery, TIMI flow grade, gender and age • (n = 53) • Endpoints: • Primary – Feasibility and safety of adjunctive FW use during primary PCI • Secondary – Markers of effective reperfusion (ST resolution, myocardial blush grade, and cTFC); peak CK and CK-MB release, change in LVEF and WMSI at 30 days compared with admission; MACE (death, reinfarction, and need for target vessel revascularization) at 30 days Circulation 2003; 108:171-176
