Özet

© 2018, © 2018 Informa UK Limited, trading as Taylor & Francis Group.Objective: To investigate the association between fetal left ventricular modified myocardial performance index (LMPI) and intrahepatic cholestasis of pregnancy (ICP) and to evaluate the value of LMPI in predicting adverse perinatal outcomes in ICP. Study design: In a cross-sectional case–control study, 40 women with ICP were compared with 40 gestational age-matched healthy controls. The isovolumetric contraction time (ICT), isovolumetric relaxation time (IRT), and ejection time (ET) were measured using the Doppler signals of the opening and closing of the mitral and aortic valves. LMPI was calculated as (ICT + IRT)/ET. An adverse perinatal outcome was defined with at least one of the following: non-reassuring fetal heart rate tracing, umbilical cord pH <7.20, the presence of meconium in amnion, and neonatal intensive care unit (NICU) admission. Results: Mean gestational age at delivery and mean birth weight were significantly lower and the incidences of cesarean section rate, non-reassuring fetal heart rate tracing, the presence of meconium in amnion, and NICU admission were significantly higher in the ICP group (p <.01). Mean LMPI, ICT, and IRT values were significantly higher in the ICP group (p <.01). The area under the receiver operating characteristic (ROC) curve for LMPI in prediction of adverse perinatal outcome was 0.740 (95% CI: 0.607–0.873, p =.001) and a cut-off LMPI of 0.41 conferred a sensitivity of 85% and a specificity of 61%. Conclusions: There is an impaired global ventricular function in ICP fetuses demonstrated by increased LMPI. High LMPI is associated with adverse perinatal outcome in ICP.
