RESUMO
This document summarises the evidence regarding the association between adverse pregnancy outcomes (APOs), such as hypertensive disorders, preterm birth, gestational diabetes, fetal growth defects (small for gestational age and/or fetal growth restriction), placental abruption, fetal loss, and the risk that a pregnant individual in developing vascular risk factors (VR) that may lead to future vascular disease (VD): coronary heart disease, stroke, peripheral vascular disease, and heart failure. Furthermore, this document emphasises the importance of recognising APOs when assessing VR in women. A history of APOs serves as a sufficient indicator for primary prevention of VD. In fact, adopting a healthy diet and increasing physical activity among women with APOs, starting during pregnancy and/or postpartum, and maintaining it throughout life are significant interventions that can reduce VR. On the other hand, breastfeeding can also reduce the future VR of women, including a lower risk of mortality. Future studies evaluating the use of aspirin, statins, and metformin, among others, in women with a history of APOs could strengthen recommendations regarding pharmacotherapy for primary prevention of VD in these patients. Various healthcare system options exist to improve the transition of care for women with APOs between different healthcare professionals and implement long-term VR reduction strategies. One potential process could involve incorporating the fourth-trimester concept into clinical recommendations and healthcare policies.
Este documento resume la evidencia que existe entre los resultados adversos del embarazo (RAE), tales como son los trastornos hipertensivos, el parto pretérmino, la diabetes gestacional, los defectos en el crecimiento fetal (feto pequeño para la edad gestacional y/o restricción del crecimiento), el desprendimiento de placenta y la pérdida fetal, y el riesgo que tiene una persona gestante de desarrollar factores de riesgo vascular (RV) que pueden terminar provocando enfermedad vascular (EV) futura: cardiopatía coronaria, accidente cerebrovascular, enfermedad vascular periférica e insuficiencia cardíaca. Asimismo, este documento destaca la importancia de saber reconocer los RAE cuando se evalúa el RV en mujeres. Un antecedente de RAE es un indicador suficiente para hacer una prevención primaria de EV. De hecho, adoptar una dieta saludable y aumentar la actividad física entre las mujeres con RAE, de inicio en el embarazo y/o postparto y manteniéndolo a lo largo de la vida, son intervenciones importantes que permiten disminuir el RV. Por otro lado, la lactancia materna también puede disminuir el RV posterior de la mujer, incluyendo menos riesgo de mortalidad. Estudios futuros que evalúen el uso del ácido acetilsalicílico, las estatinas y la metformina, entre otros, en las mujeres con antecedentes de RAE podrían reforzar las recomendaciones sobre el uso de la farmacoterapia en la prevención primaria de la EV entre estas pacientes. Existen diferentes opciones dentro de los sistemas de salud para mejorar la transición de la atención de las mujeres con RAE entre los diferentes profesionales e implementar estrategias para reducir su RV a largo plazo. Una posible estrategia podría ser la incorporación del concepto del cuarto trimestre en las recomendaciones clínicas y las políticas de atención de la salud.

INTRODUCTION: Pre-eclampsia affects 2%-8% of pregnancies and is one of the leading causes of maternal and perinatal morbidity and mortality. First-trimester screening using an algorithm that combines maternal characteristics, mean arterial blood pressure, uterine artery pulsatility index and biomarkers (pregnancy-associated plasma protein-A and placental growth factor) is the method that achieves a greater diagnostic accuracy. It has been shown that daily salicylic acid administration before 16 weeks in women at a high risk for pre-eclampsia can reduce the incidence of preterm pre-eclampsia. However, no previous studies have evaluated the impact of routine first-trimester combined screening for pre-eclampsia with placental growth factor after being implemented in the clinical practice. MATERIAL AND METHODS: This was a multicenter cohort study conducted in eight different maternities across Spain. Participants in the reference group were prospectively recruited between October 2015 and September 2017. Participants in the study group were retrospectively recruited between March 2019 and May 2021. Pre-eclampsia risk was calculated between 11+0 and 13+6 weeks using the Gaussian algorithm combining maternal characteristics, mean arterial pressure, uterine arteries pulsatility index, pregnancy-associated plasma protein-A and placental growth factor. Patients with a risk greater than 1/170 were prescribed daily salicylic acid 150 mg until 36 weeks. Patients in the reference group did not receive salicylic acid during gestation. RESULTS: A significant reduction was observed in preterm pre-eclampsia (OR 0.47; 95% CI: 0.30-0.73), early-onset (<34 weeks) pre-eclampsia (OR 0.35; 95% CI: 0.16-0.77), preterm small for gestational age newborn (OR 0.57; 95% CI: 0.40-0.82), spontaneous preterm birth (OR 0.72; 95% CI: 0.57-0.90), and admission to intensive care unit (OR 0.55; 95% CI: 0.37-0.81). A greater treatment adherence resulted in a significant reduction in adverse outcomes. CONCLUSIONS: Routine first-trimester screening for pre-eclampsia with placental growth factor leads to a reduction in preterm pre-eclampsia and other pregnancy complications. Aspirin treatment compliance has a great impact on the effectiveness of this screening program.
