Wuhan, HubeiAges 18 years+ - NCT07275515RecruitingPhase 2
Diroximel fumarate for brain bleed swelling
This study tests a medicine called diroximel fumarate to reduce swelling around a bleeding stroke (intracerebral hemorrhage). If you or your loved one have had a brain bleed within the last 48 hours and are not too severely affected, you may be able to join.
LilleAges 18 years+ - NCT07277309Recruiting
Recovery after brain injury using focused ultrasound
This study tests whether focused ultrasound can help people recover from a brain injury that has left them with a disorder of consciousness. The treatment involves a non-invasive technique that uses sound waves to stimulate brain activity.
Boston, MassachusettsAges 18–79 - NCT07277114Recruiting
Drug balloon vs stent for hardened arteries after special preparation
This trial compares two treatments for severely calcified coronary arteries: a drug-coated balloon (DCB) and a drug-eluting stent (DES). It is for people who have already had a procedure to crack or soften the calcium (like rotational atherectomy), and whose blood flow looks good afterward.
ShanghaiAges 18 years+ - NCT07275697RecruitingPhase 4
Weight loss drug and heart ablation study for AFib
This trial tests whether a weight loss medication (semaglutide) given before and after a first-time heart ablation procedure for atrial fibrillation can improve outcomes. It is for people who are overweight or obese and have certain related health conditions.
StockholmAges 18 years+ - NCT07276087Recruiting
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+ - NCT07272395Recruiting
Heart function changes after pacemaker or ICD placement
This study looks at how heart devices (pacemakers, ICDs, or CRT devices) affect the right side of the heart. Participants will have imaging tests before and after the device is placed to see how the heart functions.
Istanbul, FATIHAges 18 years+ - NCT07269366Recruiting
Surgery vs stents for heart disease with weak heart pump
This trial compares two ways to restore blood flow to the heart—bypass surgery (CABG) or stents (PCI)—in people whose heart pumps weakly (LVEF 40% or less). It aims to find which method works better for chest pain or recent heart issues.
GroningenAges 18 years+ - NCT07278609Recruiting
Safer medication use for older adults with rheumatic conditions
This study tests a program to help doctors choose safer medications for people aged 60 and older who have arthritis or other rheumatic conditions. It aims to reduce the use of potentially harmful drugs and improve overall medication safety.
Montreal, QuebecAges 60 years+ - NCT07274748Recruiting
High-intensity interval training vs functional training for stroke recovery
This study compares two types of exercise training to see which one better improves heart health, movement, and thinking skills in people who have had a stroke. It is for those who had a moderate stroke more than 6 months ago and can walk with some help.
