Impact Of Pregnancy Induced Hypertension On Newborn Left Ventricular Function Assessed By Speckle Tracking Imaging

Objective: Impact of pregnancy induced hypertension(PIH) on infant left ventricular myocardial segments, evaluation of the impact of PIH on neonatal left ventricular function by speckle tracking imaging. Methods: Selected January,2014- December,2015 Fifth Affiliated Hospital of Xinjiang Medical University, obstetric delivery within 1 week of the infant, according to inclusion and exclusion criteria collected 60 cases of PIH babies, including gestational hypertension(GH group) 30 cases, preeclampsia(PE group) 30 cases, and 60 cases of normal control neonatal(NC group), dynamic collection of all infants with standard four-chamber to measure right ventricular rapid systolic peak velocity(Vs) and peak strain rate(SRs), peak strain(S), rapid diastolic peak velocity(Vd) and peak strain rate(SRd). Results: Image 112 cases of 120 cases of neonatal successful acquisition. ALL Vs and Vd gradually decreases from the basal segments to apical segments of each group, basal segment and middle segment with a statistically significant difference(P<0.05), middle segment and apical segment with a statistically significant difference(P<0.05), all S, SRs and SRd in the basal segment, middle segment and apical segment with never statistically significant difference(P>0.05). Each segmental left ventricular wall and interventricular septum wall myocardial Vs, Vd, S, SRs and SRd in NC, GH, PE group have differences with statistical significance(P < 0.05), compared with NC group, GH and PE group value decreased(P<0.05), compared with GH group, PE group value decreased(P<0.05). Conclusion: Speckle tracking imaging can detect changes in left ventricular myocardial segments infant function. PIH have an effect on left ventricular function in infants to reduce myocardial strain function.
