- Addressing the optimal management approach for patients who are receiving single or dual antiplatelet therapy is a common and sometimes challenging clinical problem, especially for patients with coronary stents who are receiving dual antiplatelet therapy with acetylsalicylic acid (ASA) combined with a P2Y12 inhibitor. Using a case-based format, we summarize the findings of recent clinical trials and key observational studies which help inform best practices for the perioperative antiplatelet management of noncardiac surgery and coronary artery bypass graft surgery. In this review, we explore the evidence to address 3 key questions: What is the minimum duration that a surgery should be delayed after coronary stent implantation? In patients who are receiving single antiplatelet therapy with ASA, how to manage patients who require noncardiac and cardiac surgery? In patients who are receiving dual antiplatelet therapy for a coronary stent, how to manage patients who require noncardiac and cardiac surgery?
