- W2077895112 abstract "Current American Heart Association/American College of Cardiology (AHA/ACC) guidelines recommend aspirin indefinitely (Class 1A) and clopidogrel for at least 12 months (Class 1B) after placement of coronary bare metal stents (BMS). AHA/ACC guidelines for peripheral arterial disease recommend either aspirin (Class 1A) or clopidogrel (Class 1B) daily. No official guidelines exist regarding anti-platelet use after placement of non-coronary arterial BMS. A Cochrane Review and literature search of the subject determined that prospective data are lacking. The aim of this study was to determine the most commonly prescribed anti-platelet regimens of interventional radiologists (IRs) post-BMS placement. An online survey was sent to 800 IRs. The first 108 responses were collected and used as data. Respondents were grouped into categories based on the number of non-coronary arterial stents placed per month. The majority (38.9%) placed on average 0–2 per month while only 8.3% placed >10. In all groups, the majority prescribed aspirin indefinitely (42.5–72.7%) and clopidogrel for 3–6 months (33.3–67.4%). In one group, two clopidogrel regimens were tied (<3 months and 3–6 months). Very few IRs (2.8%) prescribed clopidogrel for >12 months - the official recommendation of the AHA/ACC for coronary BMS. Meanwhile, a fairly high number of IRs did not prescribe aspirin/clopidogrel for any duration (25.2% and 11.3%, respectively) while 5.6% prescribed neither. IRs placing 0–2 stents per month were the most likely to prescribe no anti-platelet agent. Some radiologists (13.9%) stated that their anti-platelet regimen is vessel dependent with longer courses of clopidogrel for renal, infrainguinal, and < 5mm arteries. Anti-platelet regimens after arterial stent placement are widely variable in the IR community. Prospective randomized control trials are needed to determine optimum regimens and to form an official society consensus statement.Tabled 1Anti-Platelet Agent Regimens Among Interventional RadiologistsDo not Routinely Prescribe this Drug<3 Months3–6 Months6–12 Months12–24 MonthsIndefinitelyChoice is Vessel Dependentaspirin25.2% (26)1.9% (2)11.7% (12)1.9% (2)1.0% (1)55.3% (57)2.9% (3)clopidogrel11.3% (12)20.8% (22)44.3% (47)9.4% (10)0.0% (0)2.8% (3)11.3% (12) Open table in a new tab" @default.
