Covert Perioperative Strokes in Older Patients Having Noncardiac Surgery (PRECISION): A Prospective Cohort Analysis
Authors' conclusion
Among patients aged 60 yr and older who had major noncardiac surgery, mainly intracranial, one in nine patients experienced a perioperative covert stroke. Covert strokes more than doubled the risk of postoperative delirium and long-term neurocognitive decline.
Study context

- Exposure
- Covert stroke vs no covert stroke
- Outcome
- Cumulative incidence of postoperative stroke (scheduled MRI brain imaging)
- Follow-up
- Within 7 days
