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.
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
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
