Hypertensive disorders in pregnancy

Hypertension refers to persistent high blood pressure. It is associated with conditions such as diabetes and obesity; it may be symptomless and in the United Kingdom (UK) as many as seven million people are living with cardiovascular disorders such as coronary heart disease, vascular dementia and stroke (British Heart Foundation (BHF) 2018). Hypertensive disorders in childbearing women are associated with maternal and fetal or neonatal morbidity and mortality (Traquilli et al 2014; Harding et al 2017) and pose specific challenges for the women, their families and those providing their maternity care. This chapter provides a brief review of the physiology relating to cardiovascular changes in pregnancy and the significance of hypertension for the mother and baby. It summarises the main types of hypertensive disorders in pregnancy and identifies the women at increased risk of developing these. Essential aspects of multi-professional and midwifery care are discussed and consideration is given to the physical and psychosocial impact of hypertensive disorders in pregnancy for the women affected.
