This study looks at whether the bacteria living in your gut can help predict your risk of heart disease. Researchers will collect blood and stool samples from 700 adults undergoing heart catheterization to compare gut bacteria patterns with signs of inflammation. The goal is to b…

This registry is collecting data from 20,000 people with coronary artery disease to see if an AI tool that analyzes CT scans of the heart can help doctors make better treatment decisions. The AI measures the amount and type of plaque in the arteries. Researchers will compare how …

This study follows over 5,700 people with coronary artery disease and mild heart damage to see if blood tests and ECGs can better predict who is at risk for sudden cardiac death. The goal is to find inexpensive markers that could help doctors decide who needs a defibrillator. Par…

This study looks at two ways to measure blood flow in partially blocked heart arteries. About 50 people with moderate blockages will get both tests and a standard one to see which is more accurate. The goal is to find a better method to guide treatment decisions.

This study was designed to find better ways to manage heart disease in veterans with severe peripheral artery disease (poor leg blood flow) who had leg surgery. It planned to track major heart problems like heart attacks or heart-related death. However, the study was withdrawn be…

This study looks back at medical records of 1,000 people who had a special test during a heart catheterization to measure blood flow in their heart arteries. Researchers want to see if the test results can predict future heart attacks, the need for another procedure, or death fro…

This study looks at how common a specific lung pressure (airway opening pressure) is in 196 adults recovering from heart surgery. Researchers will measure this pressure within an hour of entering the ICU using a simple breathing test. The goal is to understand if this pressure is…

This study was designed to test a new catheter that takes two types of pictures inside heart arteries at the same time—using sound and light. The goal was to see if this hybrid approach is safer and better at identifying fatty plaques that could cause heart attacks compared to st…

This study looks at whether giving people a personalized genetic risk score for coronary artery disease helps doctors make better decisions about prevention. About 1,000 adults with moderate heart risk will be randomly assigned to receive their risk score or not. Researchers will…

This study compares two methods for deciding which blocked heart arteries need bypass during valve surgery. The standard method uses angiography (X-ray dye), while the new method uses a computer calculation called QFR. About 792 patients will be randomly assigned to one method, a…

This study looks at 40 adults having heart surgery to see if a less invasive approach (through a small chest cut) helps preserve lung function and muscle strength better than the traditional method (cutting through the breastbone). Participants will do breathing tests, strength t…

This study was designed to see if helping heart patients with social problems like food, housing, and mental health could keep them out of the hospital. The researchers planned to screen patients and connect them to community resources. However, the study was withdrawn before enr…
