Physical and Mental Health in Takayasu Arteritis and Behçet's Disease
This study compares physical and mental health in people with Takayasu arteritis or Behçet's disease to healthy volunteers. It aims to better understand how these conditions affect day-to-day life and well-being.
Denizli, DenizliAges 18 years+ - NCT07276243Recruiting
Foam plus laser for varicose veins
This study tests if adding a laser to a foam treatment (polidocanol) works better for varicose veins than the foam alone. It may help people with small to medium varicose veins that are close to the skin.
Rio de Janeiro, Rio de JaneiroAges 21–75 - NCT07276282RecruitingPhase 3
Ziltivekimab for heart attack patients with artery plaque
This trial tests a new drug called Ziltivekimab to see if it can reduce plaque buildup in the heart arteries after a heart attack. It may help prevent future heart problems by targeting inflammation.
BernAges 18 years+ - NCT07276490Recruiting
Pacemaker Study for Heart Block
This study tests how a pacemaker affects blood flow and heart health in people with heart block. It aims to see if special pacing settings can improve how the heart works.
Tallinn, HarjuAges 18–80 - NCT07277361Recruiting
Quality of life study for Fabry disease patients aged 65+
This study looks at the quality of life of people aged 65 and older with Fabry disease. It includes patients who are receiving specific treatment and those who are not, to compare their experiences.
