Cardiac Structure and Function Studies

Did you know the heart is smaller in adolescents and adults born preterm? Prior work by others in the field also demonstrates an increased risk for heart failure. Working with a multidisciplinary team of pulmonologists, cardiologists, medical imagers, and biomedical engineers, we have conducted studies to evaluate the preterm heart. Cardiac imaging (MRI) studies demonstrate a smaller heart long after preterm birth, though for most individuals the heart function remains normal.

Additional studies by our team have evaluated the presence of cardiac fibrosis and abnormal cardiac metabolism to help explain the cause of increased heart failure risk.

Pulmonary Vascular Disease Studies

Our team previously conducted studies at the University of Wisconsin, demonstrating that a significant 45% of otherwise healthy young adults born preterm have evidence of subclinical or mild pulmonary hypertension. New studies here at UT Southwestern are using echocardiography to screen for pulmonary hypertension, as well as evaluating potential etiologies for pulmonary vascular disease in adults born preterm.
