Purpose of review: This review discusses the mortality and morbidity of hypertensive disorders of pregnancy (HDP) and the current diagnostic thresholds. It then explores measurement of variability in blood pressure (BP) during pregnancy as an opportunity to identify women at high risk of cardiovascular disease (CVD) later in life.
Recent findings: HDP is known to be associated with increased risk of long-term CVD. Current CVD prognostic tools do not incorporate a history of HDP given a lack of improved risk discrimination. However, HDP diagnostic criteria are currently based on a binary threshold, and there is some evidence for the use of variability in BP throughout gestation as a marker of CVD risk. HDP increases long-term risk of CVD. Future studies investigating changes in diagnostic criteria, including the use of BP variability, may improve long-term CVD risk prediction and be incorporated into future risk assessment tools.
