Monitoring cardiovascular function in infants with chronic lung disease of prematurity

In addition to persistent airways disease, survivors of premature birth with chronic lung disease are at risk of cardiovascular sequelae, including pulmonary hypertension, systemic hypertension, left ventricular hypertrophy, and exercise intolerance. The major treatment of pulmonary hypertension is supplemental oxygen, but drugs such as calcium channel blockers may also be required. The use of inhaled nitric oxide for its long term management is being investigated.
