STOPping Versus Continuing Antiplatelet Therapy During Noncardiac Surgery and Procedures After Next Generation Drug-eluting Stent Implantation

May 17, 2018 updated by: Yonsei University

Randomized Controlled Comparison: STOPping Versus Continuing Antiplatelet Therapy During Noncardiac Surgery and Procedures After Next Generation Drug-eluting Stent Implantation (STOP-ASP Trial)

Most previous trials support the absolute increase in bleeding risk with perioperative administration of antiplatelet. Furthermore, recent studies demonstrated that perioperative major bleeding may be related to increase cardiovascular risk. The investigators will compare the efficacy and safety of continuing versus stopping antiplatelet therapy during perioperative period in patients underwent PCI(Percutaneous Coronary Intervention) with next generation DES(Drug Eluting Stent).

Terminated

Detailed Description

Most current guidelines recommend to focus on continuing antiplatelet therapy (mostly with aspirin) during noncardiac surgery if possible. Although previous study showed efficacy of continuous antiplatelet therapy in reducing perioperative ischemic cardiovascular events, its effectiveness is still not clear between perioperative bleeding and ischemic risk. Most previous trials support the absolute increase in bleeding risk with perioperative administration of antiplatelet. Furthermore, recent studies demonstrated that perioperative major bleeding may be related to increase cardiovascular risk. The investigators will compare the efficacy and safety of continuing versus stopping antiplatelet therapy during perioperative period in patients underwent PCI(Percutaneous Coronary Intervention) with next generation DES(Drug Eluting Stent).

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Continuing aspirin
Patients in the group may continue the administration of aspirin during perioperative period.
Subject assigned to control arm will maintain antiplatelet therapy using aspirin only at least 7 days before surgery. If subject is taking one or more antiplatelet drugs, it should be changed (for subjects taking antiplatelet drug except aspirin at enrollment) or continued (for subject taking aspirin at enrollment) with low-dose, aspirin monotherapy before surgery. Cessation of clopidogrel, ticagrelor, and prasugrel should be started at least 5 days, 3 days and 7 days before surgery, respectively. Administration of aspirin will be started at the day of cessation of previous antiplatelet regimen and maintained until third postoperative day with 100 mg once a day.
Experimental: Stopping aspirin
Patients in the group may stop medication of antiplatelet drugs during perioperative period.
Subject assigned to comparison arm will stop antiplatelet therapy before scheduled surgery or procedure. If subject is taking aspirin, clopidogrel, ticagrelor, or prasugrel, it should be discontinued for 7 days, 5 days, 3-5 days, and 7 days before surgery. Antiplatelet therapy may be restarted as previous regimen at fourth postoperative day or sooner unless significant bleeding risk or bleeding event occurs.
