This study tested a noninvasive monitor that uses light to measure oxygen levels in the liver of children with heart conditions. Researchers wanted to see if this method could replace the usual needle-based blood draw. The study included 100 children undergoing heart catheterizat…

This study tested whether a special belt that creates images of the lungs (Electrical Impedance Tomography) can safely help doctors choose the best pressure settings on a breathing machine for infants under 3 years old. The study included 14 children with various serious conditio…

This study measured how often teenagers develop chronic kidney disease after having heart surgery as young children. Researchers collected blood and urine samples from 120 teens aged 10 to 15 during their regular heart check-ups. The goal was to find out how common kidney damage …

This study looked at how well a daily low-dose aspirin works in people who have both immune thrombocytopenia (low platelets) and heart disease. Only 4 adults took part. Researchers measured platelet function after aspirin to see if the standard dose is enough to prevent blood clo…

This study tested whether a systematic phone call from a medical student, supervised by a general practitioner, could reduce hospitalizations in patients with chronic heart or mental health conditions during the COVID-19 lockdown in France. Over 22,000 patients aged 70 and older …

This study looked at 320 adults who had heart surgery to see how well two different risk scores (EuroSCORE-II and POSPOM) predict the chance of dying in the hospital. Researchers calculated each patient's scores before surgery and compared them to what actually happened. The goal…

This study looked at whether orienteering (a navigation-based walk) is as good as regular walking for heart rehab. 40 people with stable heart disease took part. Researchers measured heart rate and enjoyment during both activities. The goal was to see if orienteering could be a f…

This study looked at whether viral infections and diabetes in pregnant women are linked to congenital heart defects in their babies. Researchers analyzed blood and stool samples from 114 women to detect viruses and immune responses. The goal was to gather knowledge for future lar…

This study tested whether 3D-printed heart models or augmented reality (AR) help first-year medical students understand two rare heart defects better than traditional slide lectures. 26 students took a quiz before and after learning with one of the three methods. The goal was to …

This study looked at 60 children having heart surgery with a bypass machine. It compared two types of filters—hemofilters and hemodialyzers—to see which one better removes inflammatory substances called cytokines. The goal was to find out if the cheaper hemodialyzer could be a sa…

This study tested a new parent questionnaire called ORALQUEST to assess feeding and eating disorders in children aged 9 months to 6 years. Researchers included 338 children with chronic conditions like heart defects or autism, as well as those with picky eating. The goal was to s…

This completed study looked at 800 children who survived blood cancer to see if having a congenital heart defect raises their risk of death or other health problems later in life. Researchers also checked for shared genetic links between the two conditions. The goal is to better …

This study explored whether the number of twists (coils) in the umbilical cord is connected to a baby's heart function during pregnancy. Researchers used ultrasound to measure both the cord coiling and heart function in 202 healthy pregnant women. The goal was to better understan…

This study tested an indoor air pollution intervention called AIRWISE in 20 adults aged 55 and older with heart disease. Participants received personal air cleaners, a color-changing air quality monitor, and educational materials. The goal was to see if they would use these tools…

This study looked at brain scans of 195 young adults (ages 18-30) with moderate to severe congenital heart disease to find signs of brain injury. The goal was to see if these brain changes could help predict memory or thinking problems later in life. No new treatments were tested…
