Eye scans for heart health: a study of blood vessels
This study uses an eye scan called OCTA to look at blood vessels in the retina. It compares people with certain heart or blood vessel conditions (like high blood pressure or diabetes) to healthy volunteers to see if eye changes can help detect heart disease early.

Testing a noninvasive device for heart disease risk
This trial uses a noninvasive device to examine small blood vessels in people at high risk for heart disease. It may help doctors better understand who needs preventive care.
Stockholm, DanderydAges Any age - NCT07360067Recruiting
Comparing two types of heart pacing for sick sinus syndrome
This study compares two different ways of placing a pacemaker lead to see which one better helps heart function and reduces future heart problems in people with sick sinus syndrome.
Seoul, SeoulAges 19 years+ - NCT07360418Recruiting
Follow-up study for healed diabetic foot ulcers

Beijing, Beijing MunicipalityAges 18 years+ - NCT07361679RecruitingPhase 4
Aspirin plus heparin vs aspirin alone for preeclampsia prevention
This trial tests whether adding a daily blood-thinning injection (heparin) to low-dose aspirin helps prevent preeclampsia better than aspirin alone for pregnant women at high risk.
Athens, AtticaAges 18 years+ - NCT07361783Recruiting
Heparin before hospital for heart attack
This trial tests whether giving a blood thinner (heparin) early, before you get to the hospital for a heart attack procedure, can improve outcomes. It is for people having a specific type of heart attack (STEMI) who will receive a balloon angioplasty within 2 hours.
Wuhan, HubeiAges 18 years+ - NCT07361887Recruiting
Moderate wine and healthy aging study
This study tests whether moderate wine consumption can help healthy aging by looking at tiny particles in your blood after a meal. It may help you understand how wine affects your body's cells.
Seville, SevillaAges 35–36 - NCT07362303Recruiting
Neuralert stroke monitor study for high-risk patients
This trial tests a device that monitors for stroke in adults who are at high risk after certain heart or blood vessel procedures. It could help detect a stroke early so you get treated faster.
Philadelphia, PennsylvaniaAges 22 years+ - NCT07363278Recruiting
Study of a new device for atrial fibrillation ablation
This study looks at how often silent brain lesions happen after a new type of heart procedure for atrial fibrillation (an irregular heartbeat). The procedure uses a device called the Varipulse catheter to help fix the heart's rhythm.
Seoul, Jongro-kuAges 19 years+ - NCT07363343Recruiting
Blood pressure medication study for new mothers after birth
This study tests two different drug combinations to see which works better for new mothers with postpartum high blood pressure that needs more than one medication.
Cleveland, OhioAges 18 years+ - NCT07363525Recruiting
Early experience with Tigertriever for stroke clot removal
This study looks at the early experience using the Tigertriever device to remove blood clots from large arteries in the brain. It may help researchers understand how well the device works in real-life practice for people having a stroke.
Detroit, MichiganAges 18 years+ - NCT07363772Recruiting
Mixed reality CPR training for adults
