Effect of chronic lung disease on blood pressure levels at follow up
1Department of Child Health, King's College Hospital, London, United Kingdom.
Insights
Neonatal chronic lung disease (CLD) did not lead to significant blood pressure (BP) elevation in preterm infants. Follow-up monitoring showed no hypertension symptoms or notable BP differences compared to controls.
Area of Science:
- Neonatology
- Pediatric Cardiology
- Respiratory Medicine
Background:
- Neonatal chronic lung disease (CLD) is a significant concern in preterm infants.
- Potential long-term cardiovascular complications, including hypertension, require investigation.
Purpose of the Study:
- To assess the incidence of elevated blood pressure (BP) in preterm infants with CLD.
- To compare BP levels in infants with CLD to matched controls over a 6-month period.
Main Methods:
- Prospective follow-up of 13 preterm infants with CLD and 13 matched controls.
- Monthly clinical examinations and noninvasive Doppler blood pressure (BP) measurements for 6 months.
Main Results:
- No infant in either group developed symptoms of hypertension.
- No statistically significant differences in BP levels were observed between the CLD group and the control group at follow-up.
Conclusions:
- Significant blood pressure elevation appears uncommon in preterm infants following neonatal chronic lung disease.
- Neonatal CLD may not be a primary risk factor for developing hypertension in early infancy.
Abstract:
Thirteen preterm infants (median gestational age 28 weeks) who had developed neonatal chronic lung disease (CLD) and 13 gender- and gestational age-matched controls (without CLD) were prospectively followed. The infants were seen at monthly intervals for 6 months. At each attendance the infants were examined and their blood pressure (BP) measured using a noninvasive Doppler technique. No infant developed symptoms related to hypertension and there were no significant differences in their BP levels at follow up. Our results suggests significant BP elevation is uncommon following neonatal CLD.
