Venous pulse transit time in normal pregnancy and preeclampsia.
Uncomplicated pregnancies (n = 16) were evaluated longitudinally and compared to early- (n = 12) and late-onset (n = 14) preeclampsia patients, assessed once at diagnosis. Pulse transit time (PTT), equivalent to pulse wave velocity, was measured as the time interval between corresponding characteristics of electrocardiography and Doppler waves, corrected for heart rate, at the level of renal in...
متن کاملP-218: Investigation of Association between Angiotensin II Type 1 and 2 Receptor (AT1R & AT2R) Gene Polymorphisms and Susceptibility to Pre-Eclampsia (PE) in Iranian Women
Background: Hypertension during pregnancy period along with the presence of protein in the urine, after the 20th weeks of gestation is called preeclampsia (PE). About five percent of all pregnancies are manifested with PE and its exact etiology has still remained unknown. The renin-angiotensin system (RAS) has an important role in the regulation of blood pressure during pregnancy and so pathoph...
متن کاملMaternal venous hemodynamics in gestational hypertension and preeclampsia
BACKGROUND To evaluate characteristics of venous hemodynamics, together with cardiac and arterial function, in uncomplicated pregnancies (UP), non-proteinuric gestational hypertension (GH) and preeclampsia (PE). METHODS In this observational cross-sectional study, venous hemodynamics was assessed using a standardised protocol for combined electrocardiogram (ECG)-Doppler ultrasonography, toget...
متن کاملPP078. The influence of maternal position on gestational hemodynamics.
INTRODUCTION Cardiovascular profiling is useful for gestational hemodynamic studies. Conflicting results of cardiac output evolution from third trimester pregnancy to term are frequently reported. OBJECTIVES To stress the effect of maternal position in the assessment of maternal cardiac and arterial parameters during normal pregnancy. METHODS Impedance cardiography measurements were execute...
متن کاملImportance of Anti-GRP78 Antibody in Pre-Eclampsia
Background: Preeclampsia (PE) is a pregnancy specific syndrome that is associated with high maternal and fetal morbidity and mortality. Glucose regulated protein78 (GRP78) is an Endoplasmic Reticulum (ER) protein which is expressed on the cell surfaces of trophoblast cells under stress or hypoxic condition. GRP78 has a role in aggressive behavior of invasive cells and may play a role in normal ...
