Cheongju-si, North ChungcheongAges 19 years+ - NCT07282938Recruiting
Robot hand and electrical stimulation for hand function after stroke
This test combines a soft robotic hand and electrical stimulation to help improve hand movement in people recovering from a stroke. It may benefit stroke survivors who have some ability to extend their fingers and are in the early months of recovery.
Lahore, Punjab ProvinceAges 45–65 - NCT07283159RecruitingPhase 2
Tenecteplase plus a second drug for stroke recovery
This study tests whether giving a second drug (urinary kallidinogenase) after the clot-busting drug tenecteplase can help people with moderate to severe ischemic strokes recover better. It is for patients who started treatment within 4.5 hours of symptoms.
ShenyangAges 18 years+ - NCT07283224Recruiting
Using existing data to improve multiple myeloma care
This study uses already collected, de-identified data from past multiple myeloma trials to learn more about the disease. It does not involve any new treatments or procedures.
Bologna, BoAges 18 years+ - NCT07283289Recruiting
Obstructive sleep apnea in patients with PAD
This study looks at how common obstructive sleep apnea is in people with peripheral artery disease (PAD). Participants will have a sleep test as part of their regular care.
Toulon, VarAges 18 years+ - NCT07283809Recruiting
Heart care study for patients with common heart problems
This study is collecting information about people with common heart conditions to help doctors learn how to offer better care. If you have had a heart attack, heart failure, or atrial fibrillation, your experience can help improve treatment for others.
Montevarchi, AREZZOAges 18 years+ - NCT07284082Recruiting
How Does Menopause and HIV Affect Heart Health in Women?
This study looks at how menopause and HIV together might affect a woman's risk for heart disease. If you are a woman with HIV and are either premenopausal, perimenopausal, or postmenopausal, the researchers want to see if the combination of HIV and menopause creates a higher risk.
San Francisco, CaliforniaAges 18 years+ - NCT07284446Recruiting
Depression, memory, and outcomes in heart failure patients
This study looks at how depression and memory problems affect recovery in people hospitalized with worsening chronic heart failure. It aims to find better ways to support patients during their hospital stay.
KaunasAges 18–85 - NCT07284550Recruiting
