简要总结
The myocardial tissue is the most likely structure affected by hyperglycemia. The myocardial performance index (MPI) is a pulsed wave Doppler-derived index of global myocardial function. It is defined as the sum of the isovolumetric contraction time (ICT) and isovolumetric relaxation time (IRT) divided by the ejection time (ET) The fetal right heart contributes more to the cardiac output than the left heart; therefore, it is important to assess the right ventricular function. The investigators will measure right ventricular MPI in diabetic and normal pregnancies.
详细描述
Gestational diabetes mellitus (GDM) is the most common metabolic disorder in pregnancy, with an overall prevalence of 3-7 % during pregnancy. The myocardial tissue is the most likely structure affected by hyperglycemia. The myocardial performance index (MPI) is a pulsed wave Doppler-derived index of global myocardial function. It is defined as the sum of the isovolumetric contraction time (ICT) and isovolumetric relaxation time (IRT) divided by the ejection time (ET) The fetal right heart contributes more to the cardiac output than the left heart; therefore, it is important to assess the right ventricular function.
