Why the study?

Does the Tei index detect mild cardiac dysfunction in preterm infants with mild asphyxia compared to matched controls without asphyxia?

Population

40 preterm infants, comprising 20 with mild asphyxia and 20 gestational age-matched controls without asphyxia.

Comparison

Echocardiographic assessment using a… vs Gestational age-matched preterm infants without…

Implication

Tei index may detect subclinical dysfunction in asphyxiated preterm infants missed by EF or E/A; hypothesis-generating and requires prospective validation before practice change.

Structured PICO

Does the Tei index detect mild cardiac dysfunction in preterm infants with mild asphyxia compared to matched controls without asphyxia?

P
Population
40 preterm infants, comprising 20 with mild asphyxia and 20 gestational age-matched controls without asphyxia.
I
Intervention
Echocardiographic assessment using a Doppler-derived myocardial performance index (Tei index) combining systolic and diastolic performance.
C
Comparator
Gestational age-matched preterm infants without asphyxia.
O
Outcome
Myocardial performance index (Tei index), E/A ratio, and ejection fraction measured during the fourth and seventh days after birth.surrogate

The Tei index can detect mild cardiac dysfunction in preterm infants with mild asphyxia that is not apparent using standard ejection fraction or E/A ratio measurements.
