REDUCING GLOBAL PERIOPERATIVE RISK
This resource center is jointly hosted by The American Journal of Medicine,
The American Journal of Cardiology, and the Canadian Journal of Cardiology.
Key Highlights
- The objectives were to determine if coronary computed tomographic angiography (CCTA) enhances prediction of perioperative risk in patients before non-cardiac surgery and to assess the preoperative coronary anatomy in patients who experience a myocardial infarction after non-cardiac surgery.
- CCTA was performed preoperatively. Results were classified as normal, non-obstructive (<50% stenosis), obstructive (one or two vessels with ≥50% stenosis), or extensive obstructive (≥50% stenosis in two vessels including the proximal left anterior descending artery, three vessels, or left main).
- This prospective cohort study was conducted in 12 centers in eight countries and enrolled 955 patients with, or at risk of, atherosclerotic disease who underwent non-cardiac surgery.
- The main outcome was the composite of cardiovascular death and non-fatal myocardial infarction within 30 days after surgery. The independent variables were scores on the revised cardiac risk index and findings on coronary computed tomographic angiography.
