Valvular heart disease

This study tests whether adding adenosine to the standard heart-protecting solution used during bypass surgery helps the heart recover better. Sixty adults having elective valve or bypass surgery will receive either adenosine or a placebo. Researchers will measure heart function,…

This study will test whether adding a special breathing exercise (inspiratory muscle training) to standard cardiac rehab helps heart patients recover better. About 80 adults who have been hospitalized for a heart condition will take part. The main goal is to see if the training i…

Researchers are testing a soft, wearable ultrasound patch that sticks to the chest and continuously images the heart in adults and children with severe heart conditions in intensive care. The study compares heart function measurements from the patch with results from standard bed…

This study aims to see if a new method using electrical and mechanical signals from the heart can accurately diagnose valvular heart disease. Researchers will recruit 1,300 adults with and without valve problems to compare the new test against standard echocardiography. If it wor…

This study is testing a new digital stethoscope that listens for subtle changes in heart sounds to detect coronary artery disease and valve problems earlier. Researchers will record heart sounds from 500 adults who are already scheduled for heart scans or echocardiograms. The goa…

This study tests whether closing the left atrial appendage (a small pouch in the heart) during valve surgery can prevent silent brain injuries in 100 adults without atrial fibrillation. Participants will have brain scans after surgery to check for hidden strokes. The goal is to f…

This study tests whether foot massage or kinesio taping can help older adults (65+) move better and feel less afraid of movement after heart surgery. Sixty participants will receive one of the two treatments daily for a week. Researchers will measure mobility, pain, and fear of m…

This study will create a computer tool to predict which older adults are at high risk for serious problems after heart or blood vessel surgery. It will also test if special programs before and during surgery can help prevent confusion, heart issues, and death. About 1,200 people …

This study follows 75 older adults having elective heart surgery to understand why some recover quickly while others face complications like delirium or slow recovery. Researchers will measure frailty, physical and mental function, and a blood marker of biological stress called G…

This study will compare how well heart and lung function recover after robot-assisted heart surgery versus traditional open-heart surgery. Researchers will measure exercise capacity and breathing in 80 patients before and after surgery. The goal is to see if the less invasive rob…
