Overview

The purpose of this study is to evaluate the impact of perioperative aspirin continuation on clinical outcomes in patients with a history of coronary stent implantation who are scheduled for abdominal surgery.

Detailed description

PCI with coronary stent implantation is performed for a huge number of patients with coronary artery disease. Approximately 20% of these patients undergo non-cardiac surgery within three years after PCI. However, there is a scarcity of clinical evidence regarding the efficacy of perioperative aspirin continuation on cardiovascular events.

Interventions

  • Drug Aspirin
    perioperative aspirin continuation
  • Drug Aspirin interruption
    Aspirin interruption 5-7 days before surgery

Primary outcome measures

  • a composite of death or myocardial infarction [Time frame: 30 days]
Secondary outcome measures (12)
  • Major bleeding (TIMI major/minor bleeding) [Time frame: 30 days]
  • Death/Myocardial Infarction (4th UDMI Definition)/Stroke [Time frame: 30 days]
  • Death/Myocardial Infarction (4th UDMI Definition)/Myocardial Injury (MINS) [Time frame: 30 days]
  • Myocardial Infarction (4th UDMI Definition)/Myocardial Injury (MINS) [Time frame: 30 days]
  • Death/Myocardial Infarction (ARC-2 Definition)/Stroke [Time frame: 30 days]
  • Death [Time frame: 30 days]
  • Cardiovascular Death [Time frame: 30 days]
  • Myocardial Infarction (4th UDMI Definition) [Time frame: 30 days]
  • Myocardial Infarction (ARC-2 Definition) [Time frame: 30 days]
  • Myocardial Infarction (SCAI Definition) [Time frame: 30 days]
  • Myocardial Infarction (modified POISE-2 Definition) [Time frame: 30 days]
  • Myocardial Injury (MINS) [Time frame: 30 days]

Eligibility criteria

Inclusion criteria

  • Patients with a history of coronary stenting and scheduled for abdominal surgery
  • Patients on a single antiplatelet agent

Exclusion criteria

  • Patients on dual antiplatelet therapy (DAPT)
  • Patients on anticoagulation therapy
  • Patients with a history of stent thrombosis
  • Patients with CHADS2 score >= 5
  • Patients at extremely high risk of bleeding and unable to continue preoperative aspirin
  • Patients incapable of consent, including those under 20 years of age
  • Other patients for whom either discontinuation or continuation of antiplatelet agents is deemed inappropriate by the attending physician

Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
