Beijing, Beijing MunicipalityAges 18–85 - NCT07022067Recruiting
Smartphone study for chronic coronary syndrome
This study tests if a smartphone app can help people with a chronic heart condition called coronary syndrome. It aims to make care easier and track symptoms at home.
Milan, ItalyAges 18 years+ - NCT07022210Recruiting
Low blood pressure after surgery in the recovery room study
This study looks at how often low blood pressure happens after surgery in the recovery room. It helps doctors understand and better manage blood pressure in patients who just had general anesthesia.
ZlínAges 18–105 - NCT07022340Recruiting
Heart health and resistance training for women with irregular periods
This study looks at how resistance training (like lifting weights) affects heart health in women with irregular periods. You'll either join a 16-week exercise program or a health education group.
Ann Arbor, MichiganAges 40–60 - NCT07022587Recruiting
Dissolving stent with drug for blocked heart arteries
This trial tests a stent that slowly dissolves after opening a blocked heart artery, releasing a drug to prevent reclogging. It may help people with narrowing in one or two spots that are not too hard or twisted.
Xi'an, ShannxiAges 18–75 - NCT07022847Recruiting
Using a finger sensor to predict low blood pressure during dialysis
This trial tests if a non-invasive finger sensor (PVI) can predict when blood pressure drops during dialysis. If successful, it could help prevent dangerous low blood pressure episodes.
Wuhu, AnhuiAges 18–80 - NCT07023003RecruitingPhase 4
Blood pressure medicine study for new mothers
This study compares two blood pressure medicines, nifedipine and enalapril, for women who have high blood pressure related to pregnancy or chronic hypertension after giving birth. It aims to find the best option to help new mothers manage their blood pressure.
Omaha, NebraskaAges 19 years+ - NCT07023367Recruiting
