This study tests a program called Heart-to-Heart, where community health workers help low-income patients make informed choices about cardiac rehab after a heart event. About 50 adults from Johns Hopkins Hospital will take part. The goal is to see if the program is practical and …

This study compares two techniques for guiding a needle into a blocked leg artery from the opposite direction (retrograde). One uses a live X-ray map, the other uses ultrasound. Researchers want to see which is safer and more successful in 32 people with severe leg artery disease…

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 will use tiny probes called microdialysis to measure chemicals related to blood flow, inflammation, and antibiotics right inside the amputation stump after surgery. Researchers will compare results between diabetic and non-diabetic patients to understand why some stump…

This study is creating a large registry of 14,000 people with peripheral artery disease (PAD) to compare the long-term results of treatments that use stents versus those that do not. Researchers will track outcomes like repeat procedures, amputations, and walking ability over 12 …

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 checks if a 6-minute stepper test is a reliable way to measure exercise ability in people with peripheral artery disease (PAD). Researchers will compare it to standard tests like the 6-minute walk test and a treadmill test. The goal is to find a simple, low-cost tool t…

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 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 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 better understand how blood flow and oxygen use in the legs are affected in people with peripheral artery disease (PAD). Researchers will use a non-invasive device that shines near-infrared light on the leg to measure oxygen levels. The study will include 120 p…

This study tests a non-invasive device that measures blood flow in the skin of people with severe leg artery disease. Researchers will compare results from 15 patients before and after a procedure to open blocked arteries, and also compare them to 15 healthy volunteers. The goal …

This observational study looks at how fitness level relates to bacteria in the mouth and blood flow to muscles. Researchers will collect mouth swabs, saliva, and blood samples, and measure exercise capacity in 70 adults with heart failure, peripheral artery disease, or overweight…

This study installs a 'black box' recording system in hybrid operating rooms to capture and analyze errors during vascular procedures. Researchers will study how teamwork, leadership, and the environment affect surgical performance and patient safety. The goal is to identify high…

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 creating a collection of blood, urine, and stool samples from 500 adults with or at risk for heart and blood vessel diseases. Researchers will use these samples to study inflammation, blood clotting, and other biological pathways. The goal is to build a resource tha…

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 looks at how narrowed leg arteries (peripheral artery disease) might affect heart function. Researchers will use advanced heart ultrasound to measure subtle changes in heart muscle strain in 162 participants. They will also check for links to metabolism and organ damag…

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 simple, passive leg movement called LEAP therapy in people with peripheral artery disease (PAD). Participants sit for 2.5 hours with or without the leg movement, and researchers measure blood flow, walking ability, and other health markers. The goal is to see i…
