This completed study looked at how levels of C-reactive protein (CRP), a marker of inflammation, change in 35 patients having emergency angioplasty for a heart attack. Researchers took blood samples before the procedure and at several time points up to 30 days after. The goal was…

This completed study looked at 1,000 heart attack patients to understand why some have no standard risk factors like smoking, high blood pressure, or diabetes. Researchers compared these 'SMuRF-less' patients to those with risk factors, examining their medical history, lab tests,…

This study tested whether rotigaptide, a drug that improves cell communication, can protect blood vessel function after a temporary blockage of blood flow (ischemia-reperfusion injury). Twelve healthy men received the drug or a placebo while their forearm blood flow was measured.…

This completed study looked at 12,500 cancer patients who had a type of heart attack called NSTEMI. Researchers compared those who got invasive procedures like angiography versus those treated only with medications. The goal was to see which approach led to fewer deaths in the ho…

This study looked at 43 adults having heart surgery to see if a simple blood pressure reading can accurately measure how well the heart contracts, compared to the standard ultrasound method. The goal was to test a new software tool that analyzes the blood pressure wave. This is a…

This completed study looked at 11,000 COVID-19 patients to understand how often they develop dangerous blood clots in arteries or veins. Researchers tracked clot rates, risk factors, and outcomes over 30 and 90 days. The goal was to learn more about these complications to improve…

This study looked back at 20 children under 18 who were in intensive care with heart inflammation (myocarditis) and a possible COVID-19 infection. The goal was to describe their symptoms, lab results, and heart function, and to figure out whether the virus directly damages the he…

This completed study looked at 1029 patients who had a heart attack or unstable angina and quit smoking. Researchers checked for certain gene mutations (called CHIP) in their blood. They wanted to see if these mutations are linked to a higher chance of future heart problems, like…

This study looked at 116 people who had a cardiac arrest outside the hospital and were treated with a machine called ECMO (which pumps and oxygenates blood). Researchers measured how well the heart was pumping at 28 days and 90 days after the arrest. The goal was to understand if…

This completed study followed 281 people who had a severe type of heart attack called STEMI. Researchers collected blood samples, ECGs, MRIs, and quality-of-life questionnaires to find new biological and imaging markers that could help predict outcomes like heart failure. The goa…

This study looked at 21 people who had a heart attack to see if markers of inflammation in the blood are linked to the amount of heart damage seen on MRI scans. Researchers measured inflammation levels at several time points and compared them to MRI images taken a week later. The…

This completed study looked at how different doses of aspirin, given with or without another drug called ticagrelor, affect the body's immune response. Healthy volunteers took the medications for 10-14 days, then received an injection that causes temporary flu-like symptoms to te…

This study monitored brain oxygen levels and electrical activity in 15 children aged 6 to 36 months during open heart surgery. Sensors placed on the forehead measured oxygen and brain waves every 5 minutes. The goal was to understand how these measurements relate to each other, w…

This early-stage study tested two blood-thinning drugs, vicagrel and clopidogrel, in 18 healthy adults with a specific gene type (CYP2C19 normal metabolizers). The goal was to compare how the body absorbs and processes each drug. Researchers measured drug levels in the blood and …

This study tested new MRI methods to detect bleeding inside the heart muscle after a heart attack. Researchers studied 14 patients to see if these scans could better identify damage that raises the risk of heart failure. The goal was to improve imaging, not to test a treatment.

This study looked at 362 adults who had a heart attack to understand why they waited before going to the hospital. Researchers collected information on symptoms, travel time, and other barriers. The goal is to find patterns that can help doctors and communities reduce delays and …

This completed study looked at medical records from over 24,000 people across the United States who had a heart attack. The goal was to find out how often a specific complication called hemorrhagic myocardial infarction (bleeding inside the heart muscle) occurs. Researchers also …

This study looked at two ways to assign care coordinators to older adults (65+) with heart disease or risk factors. One method used patients' own reports of difficulty coordinating care, while the other used usual triggers like hospital discharge. The goal was to see which approa…
