FerraraAges Any age - NCT06311708Recruiting
PKP2-related heart condition natural history study
This study looks at how plakophilin 2 (PKP2)-related arrhythmogenic right ventricular cardiomyopathy (ARVC) progresses over time. You'll give blood samples to check for antibodies to a virus used in gene therapy, and help doctors understand the disease better.
San Francisco, CaliforniaAges 14–65 - NCT06312631Recruiting
Home glove helps stroke survivors use their arm
This study tests a home-use glove (SaeboGlove®) that may help people who had a stroke grip and hold objects with their hand. It looks at how using the glove affects arm function and what factors help people stick with the program.
ToulouseAges 18–90 - NCT06313684Recruiting
Hybrid cardiac rehab for heart failure patients
This study tests a hybrid cardiac rehab program (both at the clinic and at home) for people with heart failure. It combines supervised exercise sessions with remote support to help improve your heart health and daily function.
SantiagoAges 18 years+ - NCT06313645Recruiting
Blood vessel aging and heart attack risk study
This study looks at how blood vessel aging relates to the type of fatty buildup in your arteries that can cause heart attacks. If you've had a recent heart attack, chest pain (angina), or minor artery disease and do not have advanced heart failure, kidney failure, active cancer, or prior bypass surgery, you may be able to join.
