Overview

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.

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
