Summary
Phonocardiogram test (PCGT) indicators, including S1/S2, D/S, and CCCTS, can effectively evaluate neonatal cardiac reserve. This method aids in identifying neonates with diminished cardiac function.
Area of Science:
- Neonatal cardiology
- Pediatric cardiovascular research
- Medical diagnostics
Background:
- Neonatal cardiac reserve assessment is crucial for identifying infants at risk.
- Current methods for evaluating neonatal cardiac function may have limitations.
Purpose of the Study:
- To develop and validate indicators using phonocardiogram testing (PCGT) for measuring neonatal cardiac reserve.
- To establish objective criteria for assessing cardiac function in newborns.
Main Methods:
- Phonocardiogram test (PCGT) was performed on 231 full-term and 154 preterm infants.
- Key indicators measured included the amplitude ratio of the first to second heart sound (S1/S2), diastolic to systolic duration ratio (D/S), and cardiac contractility change trend after stimulation (CCCTS).
Main Results:
- Full-term infants exhibited higher S1/S2, D/S, and CCCTS values compared to preterm infants.
- Significant differences (P<0.05) were observed in D/S and CCCTS between the two groups.
- A normal reference range for neonatal cardiac reserve in full-term infants was established.
Conclusions:
- The indicators S1/S2, D/S, and CCCTS show promise for evaluating neonatal cardiac reserve.
- PCGT can be utilized as a screening tool to identify neonates with reduced cardiac reserve.
