Main findingResult — go to the resultAdjusted odds ratio 4.10 95% CI 3.56–4.72Study context
- Population
- Patients ≥65 years undergoing noncardiac elective or urgent/emergent surgery1,014 cardiac events
- Participants
- 161,177 patients
- Exposure
- Urgent/emergent vs elective noncardiac surgery
- Outcome
- Postoperative cardiac event:
- MI
- Cardiac arrest
- Follow-up
- Within 30 days of surgery
Main finding
As reported in the abstract
Adjusted odds ratio
4.10
95% CI 3.56–4.72
By group
Urgent and emergent vs Elective
aOR 4.10 (95% CI 3.56–4.72)
Observational data: associations, not effects.
Further findings
Factors associated with postoperative cardiac event (adjusted)
- Increased age, higher baseline cardiac risk, peripheral vascular disease, hypertension, worse American Society of Anesthesiologist (ASA) physical classification and longer operative time associated with a postoperative cardiac event
Associations stratified by acuity (subgroup)
- Higher baseline cardiac risk more strongly associated with cardiac events in elective patients
- Worse ASA physical classification more strongly associated with cardiac events in urgent and emergent patients
- Black patients had higher odds of a cardiac event vs White patients only in urgent and emergent patients
