NCT01967355
Preeclampsia is a disease which occurs in about 6-8% of all pregnancies and is the main cause of maternal and fetal morbidity and mortality. The cause of preeclampsia is still not clear and the only therapy is preterm caesarean section. In severe preeclampsia an accumulation of triglyceride-rich lipoproteins occurs. Therefore, lipid apheresis is performed as lipid-removing therapy for treatment of preeclampsia in order to prolong pregnancy and provide the fetus more time for maturation. In this individual treatment patients with early preeclampsia (\<= 32 weeks of gestation) will be offered a H.E.L.P.-apheresis to postpone caesarean section and therefore prolong pregnancy.

Arterial hypertension (AHT) is responsible for important morbidity and mortality. The cardiac repercussion of AHT is usually assessed by electrocardiography and echocardiography, time-consuming, technically demanding examinations that require experienced operators, which limits their use for screening diastolic dysfunction. Alternative tools for the screening of diastolic function in hypertensive patients are needed. Impedance cardiography (IC) is presently used in the study of AHT and in the optimization of antihypertensive therapy. It seems an attractive and economical option to change the clinical approach for screening; however, its validation in well-defined populations is required to sustain its use in clinical practice. The IMPEDDANS study aims to validate IC for screening left ventricular diastolic dysfunction in outclinic patients with AHT, using functional echocardiography as the clinical standard. Descriptive and analytical study with analysis of the agreement between the diagnosis of diastolic dysfunction and its degree, as well as the parameters obtained by impedance cardiography and echocardiography in patients with AHT.
