CORONARY ARTERY DISEASE

This study tests whether using a special tube (EZ-Blocker) to collapse one lung during heart bypass surgery can reduce fluid buildup and the need for chest drains. The trial includes adults having planned coronary artery bypass surgery that uses the internal thoracic artery. The …

This study tested whether personalizing blood-thinning drugs based on a patient's genetics and risk factors could reduce bleeding after a heart attack. It enrolled 39 patients who had already been on standard dual therapy for a year. The trial was terminated early, so the finding…

This study tests new methods to measure pressure, blood flow, and blockage size in heart arteries. Researchers want to see if these measurements can better identify which blockages are serious enough to cause heart damage. The study involves people with known or suspected coronar…

This study looked at whether a special CT scan called FFR-CT can help emergency room doctors better diagnose coronary artery disease in patients with chest pain. The plan was to compare treatment decisions made with and without the FFR-CT results. However, the study was stopped e…

This study tested a new stress echocardiography method using regadenoson and atropine to diagnose coronary artery disease. It involved 45 adults scheduled for cardiac catheterization. The goal was to see if this faster, radiation-free approach could accurately detect significant …

This study looked at whether measuring the speed of pulse waves in arteries, combined with machine learning, could improve prediction of significant coronary artery disease in people with chest pain or shortness of breath. Researchers planned to enroll 156 patients undergoing a h…

This study tested whether taking roxadustat before heart bypass surgery could prevent sudden kidney damage, a common complication. The trial enrolled 98 adults aged 18-80 with planned bypass surgery. The drug aims to help tissues handle low oxygen better. However, the study was t…

This study looked at whether measuring a natural clot-busting substance (t-PA) released from heart arteries could predict future heart attacks or death in people with mild to moderate coronary artery disease. Researchers gave a small dose of bradykinin into the heart artery durin…

This study looked at how the heart's pumping function recovers after a short, controlled blockage of a coronary artery using a balloon. Six adults with stable coronary artery disease undergoing angioplasty had a balloon inflated in their artery for 90 seconds. Researchers measure…

This study tested whether starting with a low-cost coronary calcium scan (about $100) could safely avoid the need for a more expensive heart stress test (over $1,500) in people with chest pain. Researchers planned to enroll 48 adults aged 50 and older with suspected heart disease…

This study looked at using a special wire that measures blood pressure inside heart arteries (called FFR) to help doctors decide which blockages to treat with stents. It included 438 people with two or more blockages in the same artery. The study was stopped early, so the results…

This study tested whether a 16-week program of yoga and lifestyle changes could affect gene activity (micro RNA) and heart disease risk factors in 16 adults with coronary artery disease. Participants had either undergone a heart procedure or had non-obstructive heart disease with…

This study tested whether fentanyl, a painkiller used during heart stent procedures, reduces the effectiveness of ticagrelor, a blood thinner given to prevent clots. Researchers compared crushed versus whole ticagrelor pills in 45 patients. The trial was stopped early, so results…
