Adjunctive Devices for Patients With Acute Coronary Syndromes Undergoing Percutaneous Coronary Intervention
Current Practice for Patients Undergoing PCI
Distal embolic protection devices are recommended to be used in patients undergoing PCI of saphenous vein grafts due to previously demonstrated ability to reduce MACE. However, use of embolic protection devices in STEMI has been less well supported mainly because of underpowered clinical trials that evaluated intermediate markers. More recently, larger randomized controlled trials (RCTs) of patients with STEMI have evaluated MACE as an end point and followed patients beyond hospital discharge (typically 3 to 12 months) but have given conflicting results. Thus, the comparative effectiveness and the risk differences between these devices in patients with ACS undergoing PCI for native coronary arteries are not well established and needs to be systematically evaluated.
