An observational study in Acute Coronary Syndrome, Chronic Coronary Syndrome and Heart Failure, sponsored by Burapha University. Recruiting at 1 site in Thailand. Open to participants aged 18 Years to 100 Years. Per ClinicalTrials.gov, last updated 2026-10-14.
Sponsored by Burapha University · Observational
This prospective cross-sectional diagnostic accuracy study enrolled patients undergoing coronary angiography and left heart catheterization at Burapha University Hospital, Thailand. The diameters of the common femoral vein and common femoral artery were measured using ultrasonography, and the common FVD/FAD ratio was calculated. LVEDP, measured during left heart catheterization, served as the reference standard. An elevated LVEDP (>16 mmHg) was defined as volume overload. Diagnostic performance was evaluated using receiver operating characteristic (ROC) curve analysis.

Exclusion Criteria:
Adults undergoing clinically indicated coronary angiography and left heart catheterization were enrolled in this prospective cross-sectional diagnostic accuracy study. All participants underwent ultrasound examination of the common femoral vein and common femoral artery to measure their diameters and calculate the common femoral vein-to-artery diameter ratio. Left ventricular end-diastolic pressure was measured during left heart catheterization as the reference standard. No study intervention was administered.
Diagnostic Test: Ultrasound Measurement of Common Femoral Vein-to-Artery Diameter Ratio
Ultrasound measurement of the common femoral vein and common femoral artery diameters performed in the supine position. The common femoral vein-to-artery diameter ratio is calculated from the measured vessel diameters and evaluated as a diagnostic index for detecting elevated left ventricular end-diastolic pressure. The ultrasound examination is non-invasive and does not involve administration of any therapeutic intervention.
Left ventricular end diastolic pressure
Left ventricular end diastolic pressure measured by left heart catheterization
Time frame: During the cardiac catheterization procedure
Plan to share: No — all IPD collected throughout the trial, only IPD used in the results publication
