Introduction: Hypertensive disorders of pregnancy (HDP) are often accompanied by cardiovascular sequelae. The objective of this study was to describe the prognosis in the postpartum period of patients with HDP in Departmental University Hospital of Borgou CHUD-B from Parakou in 2020. Methods: The study was prospective with a descriptive and analytical design and was conducted from January 2020 to September 2020. Patients with HDP were recruited from the gynecology-obstetrics department and each followed for 3 months in the cardiology department. HDP was classified according to the International Society for the Study of Hypertension in Pregnancy, and blood pressure (BP) was taken according to WHO recommendations. Self-measurement of BP at home was performed to assess blood pressure control outside the hospital. Epidata 3.1 and SPSS 21 software were used for data processing and analysis. P values Results: During the study period, the hospital frequency of HDP was 15.6%. The frequency of maternal complications in the postpartum period was 28% (severe hypertension: 23.2%; eclampsia: 3.6%; puerperal psychosis: 1.2%). At the end of the three-month follow-up, blood pressure returned to normal in 73.2% of cases; it persisted in 26.8% of women. Factors associated with persistence of hypertension after multivariate analysis were, overweight/obesity RRa 8.664 [1.566 - 47.941], (p = 0.013); family history of hypertension RRa 6.499 [1.493 - 28.289], (p = 0.013); history of hypertension in previous pregnancies RRa 7.764 [1.561 - 38.601], (p Conclusion: The frequency of HDP is not negligible at CHUD-B/A. The evolution of these HDP was marked in more than a quarter of cases by complications in the postpartum period followed by a persistence of hypertension 3 months after childbirth predicted by cardiovascular risk factors.
