Ultrasound study of artery calcium in endurance athletes
Part of Hormones & metabolism clinical trials.
This study uses ultrasound (a harmless imaging test) to look at the inner lining of your leg arteries to see how much calcium has built up over years of intense endurance exercise. It aims to find out how common this calcium buildup is in athletes like you and whether it is linked to long-term training.
Summary written for real people, not researchers, by Clin2.
Who can take part

This study tests a new balloon device that scores the artery walls to treat leg artery blockages with heavy calcium deposits. It aims to see if the device helps prepare the vessel safely and effectively before placing a stent.
This study uses ultrasound to measure blood flow in the legs of people with PAD symptoms and healthy volunteers. It aims to improve how doctors assess peripheral arterial disease without invasive tests.
This study uses a special high-frequency ultrasound to look at early changes in the arteries of people with prediabetes. It may help find early signs of heart risk and guide prevention.
This study uses 3D ultrasound to see how the heart moves blood in people who exercise a lot versus those who do not. It could help understand how regular endurance training changes heart function.
This study develops and tests a new way to diagnose severe aortic stenosis (narrowing of the aortic valve) by measuring calcium buildup on the valve using heart ultrasound. If you're already getting both an ultrasound and a CT scan of your heart, this study compares how well the ultrasound method can identify severe stenosis.
This study offers former high-intensity athletes a heart check-up using advanced imaging to look for early signs of heart problems. It aims to help you understand your heart health and catch any issues early.
