Overview

Brief Summary

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.

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
