What is the clinical evidence from this study?

Study design: Cohort. Population: Coronary artery bypass grafting (CABG) (n=1786). Intervention: Preoperative chest computed tomography (CT) vs. No preoperative chest CT. Primary outcome: Perioperative cerebral stroke (p=0.223).

What question did this study set out to answer?

To evaluate the clinical impact and neurological benefits of preoperative chest computed tomography in high-risk patients undergoing coronary artery bypass grafting.

Why the study?

Neurological complications pose significant risks in CABG, and the benefits of preoperative chest CT in optimizing outcomes and reducing neurological events in high-risk patients required investigation.

Does preoperative chest computed tomography improve outcomes and reduce neurological events in patients undergoing coronary artery bypass grafting?

Population

1786 CABG patients

Comparison

Preoperative chest CT vs no preoperative chest CT

Design

Retrospective propensity-matched cohort study

Follow-up

30 days

Key result

Preoperative chest CT in CABG patients was associated with a perioperative cerebral stroke rate of 0.7% compared to 1.9% without CT (p=0.223), and a 30-day mortality of 0.2% vs 1.7% (p=0.069).

Overview

Preoperative CT was not associated with significantly lower stroke or mortality after CABG; leaves open whether routine use improves outcomes in high-risk patients.

Key Points

To evaluate the clinical impact and neurological benefits of preoperative chest computed tomography in high-risk patients undergoing coronary artery bypass grafting.
Retrospective cohort study of 1,786 patients undergoing coronary artery bypass grafting between January 2017 and June 2023, comparing those who underwent preoperative chest CT (n=435) to those who did not (n=1,351).
Multivariate regression identified baseline clinical associations with preoperative CT use, followed by propensity score matching that established two balanced groups of 413 patients each.
In the matched cohort, the perioperative stroke rate was 0.7% in the CT group compared to 1.9% in the non-CT group (p=0.223), with 30-day mortality rates of 0.2% versus 1.7% (p=0.069).
Patients evaluated with preoperative CT had a significantly higher recognized prevalence of porcelain aorta (6.3% vs. 1.5%; p=0.0003) and more frequently underwent a no-touch aorta procedure (20.3% vs. 14.5%; p=0.035).

Main Result

Absolute Event Rate: 0.7% vs 1.9%

p-value: p=0.223

Preoperative chest CT in high-risk CABG patients alters surgical strategy by detecting porcelain aorta, with a trend toward reduced 30-day mortality and perioperative stroke.

Giusti et al. (2026) conducted a cohort in Coronary artery bypass grafting (CABG) (n=1,786). Preoperative chest computed tomography (CT) vs. No preoperative chest CT was evaluated on Perioperative cerebral stroke (p=0.223). Preoperative chest CT in CABG patients was associated with a perioperative cerebral stroke rate of 0.7% compared to 1.9% without CT (p=0.223), and a 30-day mortality of 0.2% vs 1.7% (p=0.069).
