BRAIN App for dementia support
This study is testing a new app (BRAIN App) designed to help people with dementia stay connected and engaged. Researchers want to see if the app can be useful for older adults who can still communicate and have not had a recent fast decline in health.
Winchester, MassachusettsAges 65 years+ - NCT06300450Recruiting
Alert test for cholesterol meds in PAD patients
This study tests whether a special alert in your electronic health record can help doctors start the right cholesterol-lowering medication for people with peripheral artery disease (PAD) who are not already on one. The goal is to see if the alert helps get treatment started more often.
Boston, MassachusettsAges 18 years+ - NCT06313645Recruiting
Blood vessel aging and heart attack risk study
This study looks at how blood vessel aging relates to the type of fatty buildup in your arteries that can cause heart attacks. If you've had a recent heart attack, chest pain (angina), or minor artery disease and do not have advanced heart failure, kidney failure, active cancer, or prior bypass surgery, you may be able to join.
Milan, LombardyAges 18–75 - NCT06311617Recruiting
Eye Blood Vessel Changes During Pregnancy
This observational study monitors changes in the blood vessels of your retina (the light-sensitive tissue at the back of the eye) during pregnancy. Researchers want to see how pregnancy affects the eyes, which might help better understand overall health.
Nashville, TennesseeAges 18 years+ - NCT05644548Recruiting
Eye scan study for people with common health conditions
This study uses a special eye scan (OCTA) to look at how blood vessels in the retina change in people with conditions like high blood pressure, diabetes, or abnormal cholesterol. It may help doctors better understand how these common illnesses affect the eyes.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06294119Recruiting
Brain-heart-vessel interaction study in heart surgery patients
This study looks at how your brain, heart, and blood vessels work together during heart surgery. It uses simple tests to measure these connections, which may help doctors better understand your health.
San Donato Milanese, MilanAges 18 years+ - NCT06281665RecruitingPhase 4
Aspirin after preeclampsia: the TAP trial
This trial tests whether taking low-dose aspirin after giving birth can help people who had preeclampsia. It aims to see if aspirin can lower the risk of future heart problems.
Pittsburgh, PennsylvaniaAges 18–55 - NCT06259292Recruiting
HHT patient registry tracking long-term outcomes
This registry collects health information from people with HHT over time to better understand the disease and improve care. Joining does not involve any experimental treatment, but your data will help researchers learn more about HHT.
Birmingham, AlabamaAges Any age - NCT06271577Recruiting
Smartphone ECG for heart attack detection
This study tests whether a smartphone can take a 12-lead ECG (a heart tracing) quickly when someone arrives at the ER with chest pain, to help doctors spot a heart attack sooner.
Rochester, MinnesotaAges 18 years+ - NCT03318432Recruiting
Stroke recovery research registry for people with ongoing symptoms
This study is a registry that enrolls adults who have had a stroke and still have symptoms. It helps researchers learn about stroke recovery over time and may connect you to future stroke research studies.
San Francisco, CaliforniaAges 18 years+ - NCT06220721Recruiting
Preventing long-term high blood pressure after preeclampsia
This trial is testing a medication called nifedipine (a long-acting blood pressure pill) to see if it can help lower the risk of long-term high blood pressure and improve blood vessel health after a pregnancy complication like preeclampsia. It is for women who have just given birth and are still in the hospital.
Chicago, IllinoisAges 18 years+ - NCT06187012Recruiting
