Marlowe Eldridge, MD, was recently awarded a 1-year, $100,000 supplement to his R01, funded by the National Institutes of Health, National Heart, Lung and Blood Institute (NIH-NHLBI). Dr. Eldridge will be working with Co-Investigator, Kara Goss, MD (Department of Medicine - Pulmonary Medicine) on the project entitled, "Influence of Sex and Maturation on Right heart-Pulmonary Vascular coupling in bronchopulmonary dysplasia (BPD)." Female babies with BPD demonstrate improved survival over their male counterparts, although it is currently unclear if they are at higher risk of developing pulmonary hypertension. The goal of this project is to investigate the influence of sex hormones and maturation on lung and right heart function in BPD. The information gained could impact treatment strategies and predictions of disease progression.
