Comparing two imaging methods for multiple myeloma
This trial compares two whole-body imaging scans (full-body MRI using DWI and a PET/CT scan) to see which does a better job detecting and staging active multiple myeloma. If you have been newly diagnosed or are being evaluated for suspected symptomatic myeloma, joining could help doctors learn which test is best for planning your care.

Half-dose r-SAK before heart stent procedure for heart attack
This trial tests whether a half-dose medicine called r-SAK given before a primary PCI heart stent procedure improves outcomes and safety in people with a specific type of heart attack. It may help the heart recover better, but it also checks the risk of side effects like bleeding.
Nanjing, JiangsuAges 18–75 - NCT07688551RecruitingPhase 2/Phase 3
Speech therapy with brain stimulation for aphasia after stroke
This trial tests if adding a gentle brain stimulation (tDCS) to speech therapy helps people with aphasia (trouble speaking) after a stroke. If you had a stroke more than 6 months ago and have trouble naming objects, this study may be a good fit.
Charleston, South CarolinaAges 25–80 - NCT07686341Recruiting
Precision oxygen monitor study for infants
This trial tests a new type of oxygen monitor (pulse oximeter) in babies under 1 year old. It helps doctors better track oxygen levels in critically ill infants to improve care.

Tegoprazan to prevent stomach problems after stroke
This study tests a stomach-protecting medicine called tegoprazan for people who have had a stroke and are starting antiplatelet therapy. It aims to prevent stomach complications like ulcers or bleeding.
Busan, BusanAges 19 years+ - NCT07684053Recruiting
Digital screening for irregular heartbeat to prevent stroke
This study tests if using a digital device (like a smartwatch or phone) can help find an irregular heartbeat called atrial fibrillation. Finding it early may help prevent stroke, especially in people over 65.
Innsbruck, TyrolAges 65 years+ - NCT07682298Recruiting
Measuring leftover fluid in hospitalized heart failure patients
This study looks at how well we can measure leftover fluid in the body in people hospitalized for heart failure with fluid overload. It aims to help doctors better manage treatment and improve recovery.
AarhusAges 18 years+ - NCT07685938RecruitingPhase 2
Medicines to prevent heart damage from radiation
This trial tests whether common heart medicines (statins or ACE-inhibitors) can protect the heart during cancer radiation therapy. It is for adults who are about to start chest radiation and have not taken these drugs before.
Chapel Hill, North CarolinaAges 18 years+ - NCT07684924Recruiting
Early FAPI PET/MRI after a heart attack
This study uses a new type of PET/MR scan (FAPI) to look at inflammation in the heart shortly after a heart attack. It may help doctors understand recovery better and guide future treatments.
AnkaraAges 18–90 - NCT07682389Recruiting
Diagnosing heart infection causes
This study tests a new way to find the cause of infective endocarditis, a serious heart infection. It may help doctors choose the right treatment faster.
MoscowAges 18 years+ - NCT07683299Recruiting
New heart monitoring during bypass surgery
This study tests a new way to monitor your heart and blood flow during heart surgery that uses a heart-lung machine. The goal is to see if this integrated approach helps doctors make better decisions during the operation.
Medellín, AntioquiaAges 18 years+ - NCT07685639Recruiting
HEART ATTACK: A study to improve cholesterol care after a heart attack
This trial tests whether a program that uses electronic health records can help people who have had a heart attack lower their LDL (bad) cholesterol more effectively. It aims to improve follow-up care and reduce the risk of future heart problems.
Edmonton, AlbertaAges Any age - NCT07687745RecruitingEarly Phase 1
Breathing exercises for healthy blood pressure during pregnancy
This trial tests whether a simple breathing exercise device can help keep your blood pressure healthy during pregnancy. You will use a small device 5-7 days a week and sync measurements with your smartphone.
Tucson, ArizonaAges 18–55 - NCT07680595RecruitingPhase 1/Phase 2
Statins and folic acid for unstable carotid plaque
This trial tests if adding folic acid to a statin can help stabilize plaques in the carotid artery (neck artery) to prevent stroke. You may qualify if you have carotid plaque and are not already on certain supplements.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT07680634Recruiting
Heart failure care with remote home monitoring
This trial tests a new way of caring for heart failure that combines in-person clinic visits with at-home monitoring using digital tools. If you join, you may be able to have more of your check-ups from home, which could be more convenient and help your care team catch problems early.
Amsterdam, UtrechtAges 18 years+ - NCT07687576RecruitingPhase 2/Phase 3
Comparing clot removal methods for heart attack patients
This trial tests if a special device that sucks out blood clots during a heart attack is better than standard care for reducing clot size before placing a stent. It may help patients who have a large clot and a blocked artery.
Oxford, OxfordshireAges 18 years+ - NCT07687186RecruitingPhase 3
