Japanese registry for patients having lead removal from veins
This study collects information about people in Japan who need a procedure to remove heart device wires (leads) through a vein. It helps doctors understand outcomes and improve care for future patients.
Suita, OsakaAges Any age - NCT04399200Recruiting
Study apnea after stroke to prevent new heart events
This trial looks at sleep apnea (breathing pauses during sleep) in people soon after a first stroke or a TIA, to see if it can be linked to new cardiovascular (heart/blood vessel) events. It also aims to make sure you can safely follow the study and rehabilitation plan.
GrenobleAges 18–85 - NCT04417387Recruiting
Check genetics to improve heart disease risk prediction
This study looks at whether adding genetic information to a standard NHS Health Check can better predict a person’s risk of coronary artery disease (CAD). If you qualify, you may be asked to provide genetic information to help refine future risk estimates.
LeicesterAges 40–74 - NCT04437914Recruiting
Tests a smartwatch to spot heart rhythm and wiring problems
This study checks how accurately a smartwatch can detect heart rhythm and electrical “wiring” problems compared with a standard heart test. If it works well, it could help make heart monitoring easier and more accessible.
Teresina, PiauíAges 18 years+ - NCT04442334Recruiting
European registry for people with fatty liver
This registry collects health and lifestyle information from adults with suspected or confirmed fatty liver (NAFLD) to help researchers better understand the condition. You may be asked about diet, exercise, alcohol intake, and some liver-related tests.
AntwerpAges 18–100 - NCT04444128Recruiting
Testing heart risk assessment using MRI T1 mapping
This study checks whether an MRI heart scan measure called “T1 mapping” can improve how doctors estimate heart disease risk in everyday people. You may join if you’re an adult and can have a contrast-enhanced heart MRI safely.
Frankfurt am Main, HesseAges 18 years+ - NCT04464655Recruiting
10-minute heart MRI protocol for people with heart conditions
