Prognostic capabilities of coronary computed tomographic angiography before non-cardiac surgery: prospective cohort study
Why the study?
Does preoperative coronary computed tomographic angiography improve prediction of cardiovascular death and non-fatal myocardial infarction in patients undergoing non-cardiac surgery?
Population
955 patients with, or at risk of, atherosclerotic disease who underwent non-cardiac surgery, multinational.
Comparison
Preoperative coronary computed tomographic… vs Revised cardiac risk index alone
Design
Cohort, Clinicians were blinded to the results unless left main disease was…
Follow-up
30 days

Implication
CCTA may aid perioperative risk stratification in non-cardiac surgery; leaves open routine adoption given net overestimation and observational design.
Structured PICO
Does preoperative coronary computed tomographic angiography improve prediction of cardiovascular death and non-fatal myocardial infarction in patients undergoing non-cardiac surgery?
P
Population
955 patients with, or at risk of, atherosclerotic disease who underwent non-cardiac surgery, multinational (12 centers in 8 countries).
I
Intervention
Preoperative coronary computed tomographic angiography (CCTA)
C
Comparator
Revised cardiac risk index alone
O
Outcome
Composite of cardiovascular death and non-fatal myocardial infarction within 30 days after surgerycomposite
Preoperative CCTA improves perioperative risk prediction for non-cardiac surgery but leads to a high rate of inappropriate risk overestimation in patients who do not experience events.
