Coronary disease & ACSCohort study
Long-term outcomes of high bleeding risk patients undergoing percutaneous coronary intervention: a Korean nationwide registry
- Nationwide cohort study
- Korean National Health Insurance Review and Assessment Service database
Authors' conclusion
Among patients undergoing PCI, those with HBR were at increased long-term risk for both bleeding and ischaemic events, with a greater risk of mortality compared to non-HBR patients.
Study context
- Population
- Patients with stable angina or ACS undergoing percutaneous coronary intervention (PCI) in Korea, 2009–2018
- Participants
- 325,417 patients
- Exposure
- High bleeding risk (HBR) vs non-HBR
- HBRn = 66,426
- Outcome
- Co-primary: major bleeding events and ischaemic events (cardiac death, MI, ischaemic stroke)
