[De Novo Hypertensive Disorders in the Postpartum Period: Considerations on Diagnosis, Risk Factors, and Potential Intervention Strategies].

Postpartum de novo arterial hypertension (PPDNAH) is defined as blood pressure ≥140/90mmHg, without a history of hypertension during pregnancy or delivery. Its prevalence ranges from 0.3% to 27.5% of all pregnancies. Late-onset postpartum preeclampsia (LOPPP) and late-onset postpartum eclampsia (LOPPE) typically occur between 48hours and 6 weeks postpartum, although recent studies demonstrate the possibility of developing these disorders up to 12 months postpartum. While sharing risk factors with pregnancy-related disorders, they differ in some aspects such as primigravida status. Regarding prognosis, an increase in severe maternal morbidity has been observed compared to hypertensive disorders of pregnancy. This group of pathologies is often underdiagnosed, even in high-risk patients, making early identification along with strict blood pressure monitoring essential.
