Aim: To evaluate the modified myocardial performance index (Mod-MPI) in foetuses with growth restriction and compare this index with appropriate for gestational age foetuses. Material and methods: A prospective cross-sectional case-control study was conducted involving 76 singleton foetuses between 24 and 34 weeks of gestation divided into three groups (24 appropriate growth foetuses, 30 foetuses with estimated weight between the 3rd and 10th percentiles and 22 foetuses with estimated weight < 3rd percentile, according to the Hadlock table). The Mod-MPI was obtained in the plane of the four chamber view, and the spectral Doppler sample volume was placed in the lateral wall of the aorta, close to the mitral valve. Doppler of umbilical artery was normal in all cases. Analysis of variance (ANOVA) was used to compare the groups and the intra-class correlation coefficient (ICC) was used to assess intra- and inter-observer reproducibility. Results: The mean Mod-MPI in the groups of appropriate for gestational age, estimated weight between the 3rd and 10th percentiles, and estimated weight < 3rd percentile was 0.32 ± 0.05, 0.35 ± 0.05 and 0.36 ± 0.06, respectively; there was no statistical difference between the groups (p = 0.072). There was good intra- and inter-observer reproducibility (ICC = 0.726 and 0.760, respectively). Conclusion: Mod-MPI was not significantly different between foetuses appropriate for gestational age and those with growth restriction. Mod-MPI proved to be a feasible and reproducible technique.

BACKGROUND: It is known that small for gestational age (SGA) babies may be at an increased risk of cardiovascular diseases during adulthood. There is paucity of literature regarding comparative cardiac functions of SGA and appropriate for gestational age (AGA) babies in neonatal period. The present study was conceived to compare the cardiac function of term small and appropriate for gestational age (AGA) babies through a relatively novel echocardiographic index in early neonatal period. OBJECTIVES: To compare values of myocardial performance index (MPI) index (MPI = IVCT + IVRT/ET) at 48–72 hours of age among AGA and SGA babies. METHODS: Morphological and anthropometric assessment of serially born term babies was done at time of birth to recruit hundred each of AGA and SGA babies. Tissue Doppler Imaging (TDI) was done between 48–72 hours for each enrolled baby to assess both right and left ventricle MPI in each group. RESULTS: Mean±SD values for right ventricular MPI in AGA and SGA groups were 0.268 + 0.007 and 0.30 + 0.026 respectively (p <  0.001). Mean±SD values for left ventricular MPI in AGA and SGA groups were 0.25 + 0.012 and 0.30 + 0.017 respectively (p <  0.001). There was significant negative correlation between MPI values for either ventricles and the birth weight (spearmen’s rho of –0.66) (p <  0.001). Mean±SD values for LVET in AGA and SGA group were 0.304 + 0.026 and 0.266 + 0.032 respectively (p <  0.001). CONCLUSION: MPI had a higher absolute value in the SGA babies as compared to AGA babies. These observations point towards suboptimal cardiac performance among SGA babies as compared to AGA babies on the basis of myocardial performance index.
