Gastric Ultrasound Before CABG to See if Heart Function Changes Stomach Contents
Official title: Evaluation of the Relationship Between Preoperative Gastric Ultrasonography Findings and Left Ventricular Systolic Function in Patients Undergoing Elective Coronary Artery Bypass Graft Surgery
Run by Adiyaman University · NCT07898215 · Data updated 2026-11-12
This study checks whether people with weaker heart function before elective CABG have different stomach contents seen on ultrasound.

Is this trial a fit for you?
✓Likely a good fit
Adults 18 years or older scheduled for elective CABG with consent, grouped by preoperative LVEF (<40% or ≥40%).
✕Probably not a fit
Patients with emergency surgery, BMI >40 kg/m², prior upper GI surgery, or inability to undergo gastric ultrasound may not benefit from or participate in the study.

What this trial studies
This prospective, single-center observational study will enroll 50 adults undergoing elective CABG and split them into two groups by preoperative LVEF: <40% and ≥40%. Preoperative gastric ultrasonography will assess the stomach using the Perlas grading system and antral measurements in supine and right lateral decubitus positions, with the examiner blinded to LVEF and other clinical data. The study will compare gastric contents and estimated gastric volume between the two groups to identify potential factors associated with aspiration risk during anesthesia. Demographic data, comorbidities, medications, GI symptoms, fasting duration, and echocardiographic findings will be collected. No intervention is performed; ethnicity and other details are not influencing the protocol beyond standard clinical assessment.
Why it matters
Potential benefit: If successful, the findings could help tailor preoperative risk assessment for aspiration in CABG patients with varying heart function.
How similar studies have gone: Prior work using preoperative gastric ultrasound and heart function has provided insight into aspiration risk, but this specific LVEF-stratified approach in CABG is relatively novel.
