Asymptomatic carotid artery stenosis and stroke risk in patients undergoing CABG.
Article in Open heart, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivePerioperative stroke associated with coronary artery bypass grafting (CABG) is a catastrophic event. Identification of patients at risk and reduction of its incidence remains of high importance. The aim of this study was to analyse the association of different degrees of asymptomatic carotid artery stenosis (CAS) with the perioperative outcome in a consecutive series of CABG patients and to identify predictors for CABG associated ischaemic stroke.
methodsIn total, 2727 patients undergoing isolated CABG procedure at the Medical University of Innsbruck between 2010 and 2020 were included in this study. Sonography data included the severity of carotid stenosis for left and right internal carotid artery individually. The primary outcome was the 30-day stroke and mortality rate, and the secondary outcome was 5-year mortality. A Cox regression model was performed after adjustment for EuroSCORE II.
resultsLeft CAS>50% was present in 177 patients (7%) and right CAS>50% in 197 patients (7.8%). In total, 1.6% (40 patients) of the patients died within 30 days after surgery, and 1.0% (24 patients) experienced a postoperative stroke within 30 days. Patients with a carotid stenosis>90% had a higher 30-day mortality (p<0.001) and higher incidence of postoperative stroke within 30 days (p=0.005). Patients with a history of a prior stroke were at higher risk of experiencing another stroke within 30-days after surgery, with an HR of 6.829 (2.811-16.589) (p<0.001).
conclusionsAsymptomatic CAS>90% and history of stroke are both independent risk factors for perioperative stroke and 30-day mortality.
