| Main Objective: To demostrate no increasement of incidence of preterm pre-emclampsia, comparing with a control-group patients who are taking the treatment as usual, when sFlt-1/PlGF ratio is less than 38 and patients are under 24-27 weeks of pregnancy.;Primary end point(s): - Preterm preeclampsia rate (< 37 weeks) within the two arms of the high-risk group under sFlt1/PlGF ratio less than 38 between 24-27+6 weeks of pregnancy.;Timepoint(s) of evaluation of this end point: - At the end of the study period (24-27+6 - 37 weeks of pregnancy);Secondary Objective: - To demostrate that determination of sFlt-1/PlGF ratio, between 24-27+6 weeks of pregnancy, achieves to detect false positives using first-trimester pre-emclapsia screening. - To demostrate that patients within sFlt-1/PlGF ratio less than 38, between 24-27+6 weeks of prenancy, whether you suspend the treatment with ASA, it is not increase the maternal morbility or mortality. - To demostrate that patients within sFlt-1/PlGF ratio less than 38, between 24-27+6 weeks of prenancy, the suspension of ASA reduces the incidence of minor maternal hemorrhages. -To demostrate that in high-risk pre-eclampsia patients, the detection of sFlt-1/PlGF ratio less than 38 between 24-27+6 weeks of prenancy, assumes a relief for those patients who get stress as the cognisance of high-risk group assignment for patients - To know the outcome of all patients with high-risk pre-eclampsia. | — |

| Timepoint(s) of evaluation of this end point: - Along the study period. - Along the study period. - 24-27+6, 28-31+6 weeks of pregnancy - 24-27+6, 28-31+6, 32-35+6, 36 y 37 weeks of pregnancy - 24-27+6, 28-31+6, 32-35+6, 36 y 37 weeks of pregnancy - 4 months after the birth of the baby;Secondary end point(s): - Prevalence of early, preterm and late pre-eclampsia at high-risk group and ratio = 38 - Rate of adherence to the treatment assignated to high-risk screening group of patients - Stress perception by 'Perceived Stress Scale (PSS) of Cohen, S., Kamarck, T., & Mermelstein, R. This scale is evaluated the last month, having 14 items with an outcome defined by an scale of 5 points. It will be done in both groups of study. Seeing questionaries at anexo section. - Hemorrhagea along gestation at both groups of study (studying symptoms such as epistaxis, gingivorrhagia and genital bleeding) - Rate of maternal issues in both groups (sFlt1/PlGF ratio < 38 and sFlt1/PlGF ratio= 38) such as placental detachment, caesarea detected by abnormal cardiotocography, fetus death, undertaking more than 2 antidepressants, eclampsia, diseminated intravascular coagulation, maternal mortality, postpartum hemorraghea, accurate lung oedema, brain vascular hemorraghea, stroke, sepsis, income to intensive care and second-surgery needed. - Neonatal complications in both groups such as early partum, income at intensive care, Acute respiratory distress, Grade II-IV intravascular hemorraghea, patent ductus arteriosus, renal disfuntion, Necrotizing enterocolitis, intestinal perforation, sepsis, retinopathy of prematurity, Bronchopulmonary dysplasia, Periventricular leukomalacia, intrauterine growth restriction, postnatal administration of sulphactants or inotropics drugs and/or death. | — |
