Preoperative Gastric Ultrasound and Left Ventricular Function in Coronary Artery Bypass Surgery
Evaluation of the Relationship Between Preoperative Gastric Ultrasonography Findings and Left Ventricular Systolic Function in Patients Undergoing Elective Coronary Artery Bypass Graft Surgery
Source: ClinicalTrials.gov · Last updated 30 Oct 2026
Brief summary (registry, in English)
This study aims to investigate whether reduced heart function is associated with differences in stomach contents before elective coronary artery bypass graft (CABG) surgery. Patients undergoing elective cardiac surgery will be divided into two groups based on their left ventricular ejection fraction (LVEF), a measure of how well the heart pumps blood: patients with an LVEF below 40% and patients with an LVEF of 40% or higher. Before surgery, the researchers will use ultrasound to examine the stomach. They will assess the presence and amount of stomach contents using the Perlas grading system and ultrasound measurements of the gastric antrum. The main objective is to compare gastric ultrasound findings between the two groups. The researchers will also evaluate estimated gastric volume and the frequency of stomach findings associated with a higher risk of aspiration during anesthesia.
