[Dual Antiplatelet Therapy in the Perioperative Period - To Continue or Discontinue Treatment?].

 For secondary prevention of acute coronary syndrome, guidelines recommend dual antiplatelet therapy (DAPT) with acetylsalicylic acid and a P2Y12 receptor antagonist such as clopidogrel, prasugrel or ticagrelor for a period of 12 months. Often, uncertainty exists with respect to surgical or diagnostic procedures in these high-risk patients: can the DAPT be continued without interruption? If not, what is the recommended withdrawal strategy? What should be considered for the perioperative management?  An interdisciplinary group of experienced experts in the fields of cardiology, cardiac surgery, gastroenterology, anaesthesiology, intensive care and haemostaseology developed recommendations relevant to daily clinical practice based on the current scientific evidence.  These recommendations include instructions for evaluating the patient- and procedure-specific risks of bleeding and ischaemia, general recommendations regarding the DAPT withdrawal strategy, and specific guidance for frequent surgical or diagnostic procedures.  This article aims to facilitate the management of patients with DAPT for all medical disciplines involved, thereby ensuring optimal care of patients during the perioperative period.
