Postpartum Hypertension Management and Monitoring

Postpartum hypertension encompasses elevated blood pressure emerging or persisting after childbirth and remains a significant contributor to maternal morbidity and long-term cardiovascular risk. It includes new-onset hypertension and the continuation of hypertensive disorders of pregnancy, such as gestational hypertension and pre-eclampsia. Current management revolves around early detection, risk stratification and timely intervention to prevent complications such as stroke, eclampsia and end-organ damage. Blood pressure monitoring in the puerperium has evolved from in-clinic assessments to home and ambulatory monitoring, facilitating patient-centred care. Pharmacological strategies employ antihypertensive agents selected for safety during breastfeeding and efficacy in stabilising systolic and diastolic pressure, with drug classes including beta-blockers, calcium-channel blockers, angiotensin-converting enzyme inhibitors and vasodilators. Non-pharmacological measures, such as fluid management, rest and patient education, complement medication. Multidisciplinary follow-up, often extending beyond the traditional six-week postnatal visit, integrates cardiovascular imaging, laboratory biomarkers and telehealth to personalise therapy and identify women at risk of chronic hypertension and cardiovascular disease.

Postpartum Hypertension Management and Monitoring publication trend

The graph below shows the total number of articles in postpartum hypertension management and monitoring across all publications each year (not limited to Nature Index journals).

Technical terms

Gestational hypertension: New-onset elevated blood pressure after 20 weeks’ gestation without proteinuria or end-organ dysfunction.

Pre-eclampsia: A hypertensive disorder of pregnancy characterised by persistent hypertension and signs of organ involvement, such as proteinuria, after 20 weeks’ gestation.

Ambulatory blood pressure monitoring (ABPM): Continuous recording of blood pressure over 24 hours, allowing assessment of daily variations and nocturnal dipping patterns.

Echocardiography: Ultrasound imaging of the heart used to evaluate chamber dimensions, wall thickness, systolic and diastolic function.

Cardiovascular magnetic resonance (CMR): Advanced imaging technique providing detailed assessment of cardiac structure, function and tissue characteristics.

Global longitudinal strain (GLS): A measure of myocardial deformation representing the percentage of longitudinal shortening of the left ventricle during systole.
