Summary
Ophthalmic artery Doppler waveforms in small for gestational age newborns may indicate future cardiovascular disease risk. This non-invasive method can help assess cardiovascular health in infancy.
Area of Science:
- Neonatal Medicine
- Cardiovascular Physiology
- Diagnostic Imaging
Background:
- Ophthalmic artery Doppler waveform (OADW) is a potential indicator of systemic atherosclerosis severity.
- Cardiovascular disease (CVD) risk assessment in newborns is crucial for long-term health outcomes.
Purpose of the Study:
- To evaluate cardiovascular disease risk in newborns small for gestational age (SGA) compared to appropriate for gestational age (AGA) infants.
- To investigate the utility of OADW in identifying potential CVD risk in neonates.
Main Methods:
- Comparison of OADW parameters between SGA and AGA newborn groups.
- Analysis included median Doppler maximums (max A, max D), resistivity index (max RI), and pulsatility index (max PI).
- Multiple linear regression analysis was performed on SGA group data.
Main Results:
- SGA newborns exhibited significantly lower maximum average velocity (max A) and maximum end diastolic velocity (max D) compared to AGA infants.
- SGA newborns showed significantly higher maximum resistivity index (max RI) and maximum pulsatility index (max PI).
- Max A and max PI were significantly correlated with other variables in the SGA group.
Conclusions:
- OADW in SGA newborns may be linked to future, currently undetectable, cardiovascular disease risk.
- OADW offers valuable information for estimating future cardiovascular health in neonates.
- This non-invasive technique may aid in early identification of at-risk infants.

01:19Assessing Blood pressure using a doppler ultrasound
To obtain accurate blood pressure measurements in clinical settings, especially when traditional methods are insufficient, healthcare professionals utilize the Doppler ultrasound technique. This method uses high-frequency sound waves to detect blood flow within the arteries, which is crucial for patients with conditions that complicate circulatory system assessment.

01:14Fetal Circulation
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
