This study collects tissue samples from women with and without preeclampsia during C-sections to examine blood vessel function. Researchers focus on a protein called AT2R, which may play a role in the condition. The goal is to better understand how preeclampsia affects blood vess…

This study is testing whether adding genetic and imaging information to standard risk assessments can better predict heart disease in 30,000 healthy Italian adults aged 40-80. Participants will have their risk calculated using traditional methods and then again with the added dat…

This study looks at how long new mothers with high blood pressure should monitor their blood pressure from home after giving birth. Researchers will compare a 2-week program to a 6-week program to see which leads to better health outcomes. About 400 women who have already joined …

This study is testing a virtual patient navigation program for 260 English, Chinese, or Spanish speakers with breast cancer or heart disease. The goal is to see if a phone-based portal can help underserved people get the support they need, even though it won't fully replace in-pe…

This study aims to understand how tiny particles called exosomes, released from the placenta, may cause preeclampsia—a serious pregnancy condition involving high blood pressure. Researchers will collect blood and placenta samples from 64 women with preeclampsia and study these pa…

This study is testing a simple bedside device called a bioimpedance analyser to measure body water changes in pregnant women. Researchers will compare its readings to standard fluid charts in 900 women, including those having planned C-sections, induced labor, or conditions like …

This study is for pregnant people at risk for preeclampsia who are taking aspirin as part of their care. Researchers want to see how aspirin changes tiny particles from the placenta in the blood. They hope to create a blood test that can better monitor placental health and predic…

This study looks at whether early-onset preeclampsia (a serious pregnancy condition) affects the size of two brain areas in the fetus: the fornix and hippocampus. Researchers will use ultrasound to measure these areas in 84 pregnant women—half with early-onset preeclampsia and ha…

This study follows over 10,000 Moroccan adults for 10 years after a heart screening. Researchers will track heart attacks, strokes, and heart-related deaths to build a risk score tailored to the Moroccan population. The goal is to better predict and prevent heart disease in Moroc…

This study is building a biobank of blood and tissue samples from 500 patients undergoing cardiac surgery. Researchers will analyze these samples to better understand the causes and progression of heart disease. The goal is to improve future diagnosis and treatment, but no new th…

This study is testing whether a blood test that measures certain markers (sFlt-1/PlGF) can help doctors decide when to deliver babies in women with mild preeclampsia at term. Instead of automatically inducing labor at 37 weeks, women with normal test results would wait until 39 w…

This study looks at whether a blood gas measurement called base excess differs between pregnant women with severe preeclampsia and those with normal blood pressure. Researchers will test 100 women before delivery to see if abnormal base excess levels are linked to more severe dis…

This study follows 2,800 pregnant women and their children in Weifang, China, from early pregnancy until the child turns 18. Researchers collect data on diet, lifestyle, and environment, along with blood, urine, and other samples. The goal is to understand how factors before and …

This study aims to see if voice recordings from a smartphone can help detect heart disease. Researchers will collect voice samples and health data from up to 1 million adults using the Mayo Clinic app. No treatment is given; the goal is to gather information for future AI tools.

This study looks at why low-dose aspirin sometimes fails to prevent preeclampsia, a serious pregnancy complication. Researchers will study genetic and platelet factors in 130 women who had preeclampsia before and took aspirin in a later pregnancy. The goal is to understand why so…

This study tests whether pregnant women with complications like pre-eclampsia or fetal growth restriction can use a remote device at home to monitor their baby's heart rate. Sixty participants between 32 and 37 weeks of pregnancy will try the device daily. Researchers will check …

This study is testing whether a smartwatch, combined with artificial intelligence and remote doctor check-ins, can help detect heart issues like atrial fibrillation and unstable angina earlier than usual. Researchers at the University of Sao Paulo will enroll 520 adults with hear…

This study is observing 900 adults in Greece who have both chronic obstructive pulmonary disease (COPD) and at least one heart condition. Researchers will track their health for two years, recording lung flare-ups, heart complications, hospital visits, and quality of life. The go…

This study looks at whether tiny particles from blood vessels, found in urine, can help predict which pregnant women with high blood pressure will develop a dangerous condition called pre-eclampsia. Researchers will measure these particles in 110 pregnant women at two points duri…

This study looks at how pregnant women at risk for preeclampsia process aspirin and how that relates to signs of metabolic problems. Researchers will measure aspirin byproducts in blood and urine, along with other health markers, in 50 women. The goal is to better understand why …

This study follows 100 women who had preeclampsia, HELLP syndrome, or kidney problems during pregnancy. Researchers will measure blood vessel stiffness and collect blood samples for a biobank. The goal is to better understand long-term heart and kidney health after these conditio…
