“…There were no significant differences between the 2 groups concerning gestational age, length, weight, or body surface area. The MCW data showed that GWI and GCW, including z-score using a normal range in the neonatal period, 16 was significantly higher in infants with GDM and <6.5% HbA1c than infants with GDM and >6.5% HbA1c (Table 3B). The color M-mode data showed that IVPD and IVPG were higher in unclear.…”

Background: This study used echocardiography to investigate non-invasive myocardial work (MCW) indices in infants born to mothers with diabetes mellitus (DM) in pregnancy (gestational DM: GDM), including those diagnosed under novel classification criteria and those with pre-existing DM. Methods and Results:This single-centered, retrospective study included 25 infants born to mothers with GDM (termed "infant with GDM"), which was diagnosed by oral glucose tolerance test results during pregnancy or the presence of diabetes before the current pregnancy. We evaluated the relationship between the infant's MCW, such as global constructive work (GCW), global work index (GWI), global work efficiency (GWE), and global wasted work (GWW), and the mother's GDM maximal HbA1c during pregnancy. HbA1c level in GDM significantly negatively correlated with GWI* (r=−0.565) and GCW* (r=−0.641). In infants with GDM, GWI and GCW were significantly higher with <6.5% HbA1c than in those with >6.5% HbA1c GDM; however, the specific-layer global longitudinal strain analyses did not show any significant differences between the groups. The pressure-strain loop in infants with >6.5% HbA1c in GDM tended to be smaller than in those infants with <6.5% HbA1c GDM. Conclusions:The hyperglycemic environment of GDM leads to impaired MCW in the infants. MCW is useful for screening for cardiac illnesses among infants with GDM. Appropriate maternal blood glucose management while maintaining HbA1c <6.5% might be beneficial for the cardiac performance of infants with GDM.

“…[13][14][15] Recently, we established the reference ranges for MCW parameters in healthy newborns. 16 Because there have been few studies reporting non-invasive MCW measurement in infants born to mothers with GDM (termed "infant with GDM") using the new definition of GDM, that was the focus of the present study.…”

To investigate noninvasive pressure-strain loop (PSL) combined with two-dimensional speck tracking imaging and left ventricular pressure measurement in the evaluation of cardiac function changes in anemia of prematurity (AOP) with different modes of respiratory support, and to explore its value in detecting subclinical myocardial injury in preterm infants. This retrospective study included 79 preterm infants with anemia, according to different modes of respiratory support, who were divided into invasive respiratory support group (39 cases) and noninvasive respiratory support group (40 cases). A control group of 40 nonanemic preterm infants with matched age, sex, and gestational age were also included. Complete echocardiography was performed for each included infant. There are PSL parameters that used to evaluate cardiac function, including global longitudinal strain (GLS), global work index (GWI), global constructive work (GCW), global wasted work (GWW), and global work efficiency (GWE) among the three groups were compared. Compared with the control group, the value of GWI, GCW, and GWE were significantly lower and GWW was higher in the AOP groups (P < 0.05), and GWI, GCW and GWE were much significantly lower in the invasive respiratory support group than in the noninvasive respiratory support group (P < 0.05). There was no significant difference in GLS among the three groups (P > 0.05). Noninvasive PSL analysis can quantitatively assess myocardial work in AOP with different respiratory support, which is more sensitive than other conventional echocardiographic indices. This technique may provide a new method for monitoring subclinical myocardial injury with AOP.
