CABG

This study compares two common heart procedures—bypass surgery (CABG) and stenting (PCI)—in 358 people with weak hearts (ejection fraction 40% or less) and multiple blocked arteries. The goal is to see which approach leads to better survival, fewer heart attacks or strokes, and i…

This study tests whether custom pressure-guided elastic bandages can prevent leg swelling and other complications after coronary artery bypass surgery. About 106 adults having bypass surgery with leg vein removal will be split into two groups: one gets the custom bandages, the ot…

This study tests whether taking a low dose of colchicine (a medicine used for gout) every day for a year can prevent the new blood vessels created during heart bypass surgery from failing. About 100 adults who recently had bypass surgery will take colchicine or no extra treatment…

This study tests a new pain medicine called tafalgin against morphine in 100 adults recovering from coronary artery bypass grafting (CABG). Participants receive either a single shot of morphine or tafalgin when their pain level is high. The goal is to see if tafalgin controls pai…

This study tests whether adding virtual reality (VR) nature scenes to exercise training helps people who had heart bypass surgery breathe easier and feel better. 66 adults with low heart function and ongoing shortness of breath will be split into three groups: one does circuit tr…

This study compares two solutions used to protect the heart during coronary artery bypass surgery: standard blood cardioplegia and del Nido cardioplegia. Researchers will use MRI scans to see which solution better preserves heart muscle. The trial involves 60 adults with multives…

This study gives low-dose interleukin-2 to people who have had a heart attack and are scheduled for bypass surgery. Researchers want to see how the drug affects certain immune cells (regulatory T cells) inside heart tissue compared to blood. The goal is to understand whether thes…

This study is testing a tool called Transit-Time Flow Measurement (TTFM) that uses sound waves during heart bypass surgery to check blood flow through the new blood vessels. The goal is to see if using this tool helps the grafts stay open longer. About 1242 adults having their fi…

This study follows 160 heart failure patients who are scheduled for coronary artery bypass surgery. Researchers want to see if measuring a substance called GDF-15 in the blood before surgery can help predict who will have serious heart problems in the next year. The study does no…

This study looks at four simple physical tests—like timed walking and standing up from a chair—to see which one best measures how well people recover after coronary artery bypass surgery. About 150 adults aged 30-50 will be tested on the third and fifth day after surgery. The goa…

This study tests whether artificial intelligence can evaluate how well surgeons perform a key step in heart bypass surgery. Researchers will compare AI scores to those from human experts. The trial involves 284 patients undergoing bypass grafting and aims to see if AI can reliabl…

This study will follow 10,000 people who come to a clinic in Davos, Switzerland for cardiac rehabilitation after a heart attack, surgery, or other heart problem. Researchers will collect health data, blood samples, and genetic information to understand what helps people recover b…
