Pulmonary Vascular Disease and Cardiac Performance in Extreme Preterm Infants

This observational study tracks heart and lung health in babies born extremely prematurely (before 29 weeks of pregnancy), following them from the newborn intensive care unit through early childhood to understand how pulmonary pressures and heart function evolve over time. The researchers hypothesize that very preterm infants often have higher-than-normal lung pressures (pulmonary hypertension) and abnormal heart function, and that early identification with advanced ultrasound techniques could predict which children are at greater risk for long-term complications. Infants born before 29 weeks of gestation admitted to the NICU or followed at clinic after such an admission are eligible, excluding those with significant congenital heart defects or genetic disorders like Down syndrome. Participation involves echocardiography (heart ultrasound) assessments at various ages with no experimental treatments involved.
