Prognostic capabilities of coronary computed tomographic angiography before non-cardiac surgery: prospective cohort study.

ABSTRACT:

Objectives

To determine if coronary computed tomographic angiography 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.

Design

Prospective cohort study.

Setting

12 centers in eight countries.

Participants

955 patients with, or at risk of, atherosclerotic disease who underwent non-cardiac surgery.

Interventions

Coronary computed tomographic angiography was performed preoperatively; clinicians were blinded to the results unless left main disease was suspected. Results were classified as normal, non-obstructive (<50% stenosis), obstructive (one or two vessels with ≥ 50% stenosis), or extensive obstructiv
