Subendocardial infarction associated with ventricular hypertrophy in preterm infants with chronic lung disease

Abstract

We describe three preterm neonates with bronchopulmonary dysplasia, pulmonary hypertension and ventricular hypertrophy who incurred subendocardial infarctions, as evidenced by electrocardiographic, laboratory or autopsy findings. We propose that cardiac hypertrophy contributed to the risk for subendocardial ischemia and infarction, and suggest diligence for this complication.
