Brief summary
Medical imaging is increasingly important for understanding diseases, detecting them early, and personalizing treatments. New imaging techniques, which can measure processes in the body without surgery, are opening the door to a more precise approach to medicine. Instead of relying on general probabilities, this technology allows us to analyze specific factors in a person's health, leading to better predictions and targeted treatments. One key challenge in medicine today is reducing "residual individual risk"-the remaining health risks that current treatments don't fully address. This involves understanding how factors like age, sex, genetics, and environment affect our health, particularly when it comes to conditions like heart and liver disease. By using imaging to distinguish between normal aging and disease, we can better assess individual health risks. The current project will create a large collection of medical images linked with health data from a broad population across France. Using advanced, non-invasive techniques such as MRI and ultrasound, researchers will analyze the heart, blood vessels, and liver in detail, considering factors like gender and health risk profiles. This will help improve our understanding of these diseases, which are often silent and not well understood, providing direct benefits to the participants. Ultimately, the goal is to optimize imaging technologies for large-scale studies, which will help enhance early detection and prevention for everyone.
Interventions
* Cardiovascular MRI * Hepatic MRI * Hepatic ultrasound
* Urinary pregnancy test for women of childbearing age. * Blood sample for cardiometabolism profiling * Blood samples for biobanking (according to the information and consent form) * Impedancemetry * AGE reader: combined non-invasive measurement of aging and accumulation of glycated proteins in the subcutaneous tissue will be performed with a CE-marked device.
* Review of risk factors * Review of previous history * Recording of current medication (dci, dose, start date) * Recording of medication in the last 6 months and discontinued since (dci, dose, start date)
Echocardiography including: 12-lead digital ECG
