Background
The prognostic role of procedural complexity when discontinuing aspirin in patients on oral anticoagulation undergoing percutaneous coronary intervention (PCI) has never been studied.
Methods
Ischaemic events were compared in 256 consecutive patients according to procedural complexity and aspirin on discharge. PCI complexity was defined according to the high-risk features for ischaemic events in the current guidelines
Results
Forty percent patients had stable presentation. In patients with complex PCI, ischaemic events were significantly higher when discharged without aspirin (adjusted HR 3.66, (95% CI 1.07 to 12.47), P = 0.038). This was driven from both target vessel failure and de-novo coronary lesions. Ischaemic events were comparable between patients with complex PCI on aspirin and those who underwent non-complex PCI.
Conclusions
Procedural complexity in patients with indication for oral anticoagulation undergoing PCI should be factored in when deciding optimal antithrombotic therapies. Aspirin discontinuation in patients with high-risk PCI features should be discouraged.
