Heart ultrasound study in healthy blood donors
Part of Injuries & trauma clinical trials.
This study uses a heart ultrasound (echocardiography) to see how the heart changes when healthy volunteers donate blood. If you're a healthy adult who can donate blood, you may help researchers understand more about blood donation's effect on the heart.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 40 years old.
- You are generally healthy and eligible to donate blood under French rules.
- You do not have a body mass index (BMI) below 18 or above 30, and you weigh no more than 96 kg (about 211 lbs).
- You have never had heart valve disease, blocked heart arteries, or heart failure.
- You are not pregnant, breastfeeding, and do not take certain medicines (like blood pressure, seizure, or anti-inflammatory drugs) that might affect how your body handles losing blood.

This study uses ultrasound (echocardiogram) to see how a blood transfusion affects heart function in people with low red blood cells (anemia) in the emergency room.
This study teaches medical students and doctors how to perform a specific heart ultrasound measurement (LVOT VTI) on healthy volunteers. Researchers want to see how well beginners can learn and perform this technique.
This study collects small blood samples (and sometimes samples during treatment) to help researchers understand diseases involving the heart, inflammation, and blood vessel function. It may help improve future tests and treatments by giving scientists usable human data.
This trial uses low-intensity ultrasound to see if it can safely measure or affect heart function in healthy people. It aims to understand how the heart works during a simple, non-invasive procedure.
This study tests a new digital method for analyzing heart ultrasound images. Researchers want to see if computer software can help doctors read heart scans more accurately and quickly.
This trial is studying heart and blood circulation problems that may happen during a certain type of organ donation (called Maastricht 3). It is for people who donate organs and those who receive them. The goal is to see how the level of oxygen in the blood affects these problems.
