This study will enroll 5,000 adults with chronic heart conditions like heart failure, high blood pressure, or aortic stenosis. Participants will wear a Prolaio digital health patch that monitors heart rate, breathing, and other vital signs. The goal is to observe how these condit…

This study is reviewing medical records from 5,000 heart and blood vessel surgery patients to find factors that influence recovery and survival. Researchers are looking at data from 2001 to 2013 to identify what leads to complications or death after surgery. The goal is to improv…

This study collects small heart tissue samples from 400 adults undergoing heart procedures. Researchers will analyze these samples to find new markers that could help diagnose heart diseases earlier and better understand how the heart works in health and disease. The goal is to i…

This study looks at what happens to the back of your eye (the choroid) after you eat sugar. Healthy adults without diabetes will consume 30 grams of glucose tablets, and researchers will measure changes in choroidal thickness over time. The goal is simply to learn more about how …

This study looks at how short periods of high oxygen affect blood flow in the brains of ICU patients on breathing machines. Researchers will briefly increase the oxygen given through the ventilator and use ultrasound to monitor brain artery blood flow. The goal is to understand t…

This study aims to understand the natural bacteria living on the surface of the eye in both healthy people and those with certain eye conditions. Researchers will collect eye swabs from 500 adults in middle Tennessee to build a database of what a normal eye microbiome looks like.…

This study uses a special eye scan called OCTA to measure the density of tiny blood vessels in the retina. Researchers will compare results from 64 people—half with cardiovascular disease and half healthy—to see if the scan can reliably detect vessel changes linked to heart probl…

This early-stage study explores whether stem cells made from a person's own blood can help repair damaged blood vessels in the eye caused by diabetic retinopathy. Researchers will create these stem cells in a lab and test them in animals to see if they can grow new, healthy blood…

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 tests a new 4D microscope-integrated OCT system for the first time in people during eye surgery. Researchers want to see if the system is easy to use, safe, and can clearly show eye structures. Five adults having eye surgery will take part. The goal is to improve imagi…

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 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 aims to create a database of eye images using a new holographic Doppler laser device. The goal is to better visualize and measure blood flow in the retina and choroid, which is important for diagnosing eye diseases. About 123 adults, both with and without eye condition…

This study gathers standard eye movement and pupil data from 200 healthy volunteers, children, and people with eye or brain conditions using a VR headset called neos™. The headset shows images and tracks where participants look, how their pupils react, and how their eyes move. Th…

This study is testing a new non-invasive device that uses laser speckle to measure blood flow and structure inside the eye. Researchers will compare these images with standard vision tests in 500 people with various retinal conditions. The goal is to see if this technology can be…

This study is for people with diabetic macular edema, a condition that causes vision loss. Researchers want to see if certain substances in the blood and patterns on eye scans can predict how well a patient will respond to two common treatments: anti-VEGF injections or a dexameth…

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 tests a special microscope that takes live 3D images inside the eye during surgery. It aims to help surgeons see better when treating conditions like retinal detachment, macular holes, and cataracts. About 262 people will take part, including healthy volunteers and sur…

This study aims to understand how blood vessels around the fovea (a key part of the eye for sharp vision) develop in infants with retinopathy of prematurity, a leading cause of childhood blindness. Researchers will use a special imaging technique (OCTA) to track changes in blood …

This study tests a new, more comfortable eye camera (WiSLO) designed for children and adults. Researchers want to see if it takes better pictures and is less bothersome than current cameras. About 42 people with or without eye disease will have their eyes photographed with both t…

This study looks at why some premature babies develop retinopathy of prematurity (ROP), an eye condition that can affect vision. Researchers think fatty acids from the mother may play a role. They will collect blood, placenta, and cord samples from 135 mothers and their preterm o…

This study looks at how a cholesterol-regulating protein called LXR might protect the eyes in people with diabetic retinopathy. Researchers will take blood samples from 104 adults with or without diabetes to test how certain blood cells function. The goal is to understand the bio…
