Risk of AMI after hip/knee surgery

This large retrospective cohort found the risk of AMI was markedly elevated within the 2 weeks after elective hip surgery (hazard ratio 26) and 2 weeks after elective knee surgery (hazard ratio 31). It remained elevated for 2-6 weeks after hip surgery (hazard ratio 5) but not for the 2-6 weeks after knee surgery (compared to controls). The authors suggest ongoing AMI risk assessment for patients up to 6 weeks after hip surgery and up to 2 weeks after knee surgery (abstract)
