Oral supplement effect on blood vessel health in obesity and hypertension
This trial tests whether an oral supplement made from special fats (called Specialized Pro-resolving Mediators) can help reduce blood vessel damage caused by inflammation in people with obesity and high blood pressure. If you have well-controlled high blood pressure and are obese, you may be able to join.
ParisAges 18–85 - NCT07038408Recruiting
Comparing two procedures for opening blocked heart arteries
This trial tests whether using a drug-coated balloon with a scaffold is better than using a scaffold alone for people with narrowed or blocked heart arteries. It looks at which method helps the artery stay open longer.
TallinnAges 18–68 - NCT07039149Recruiting
Dual antiplatelet therapy for acute coronary syndrome
This trial tests giving two blood-thinning medicines early to people who have had a heart attack or unstable chest pain. Researchers want to see if this approach reduces future heart problems.
