PCI refers to percutaneous coronary intervention, and post-procedure upper gastrointestinal bleeding is a relatively common complication that occurs within 1 year after the procedure, especially in the first month.
Percutaneous coronary intervention (PCI) refers to the therapeutic method of improving myocardial perfusion by unblocking narrowed or even occluded coronary artery lumens via cardiac catheterization, which can be used for chronic stable coronary artery disease with a wide range of myocardial ischemia, high-risk unstable angina, and non-ST-segment elevation myocardial infarction and acute ST-segment elevation myocardial infarction and other medical conditions.
Since antiplatelet drugs need to be applied before and after PCI, and intravenous heparin anticoagulation needs to be given during the operation, bleeding during the perioperative period (defined as from 5-7 days before the operation to 7-12 days after the operation) is a more common complication of PCI.
Once gastrointestinal bleeding occurs, early intervention should be made to avoid exacerbation of the condition.
