Introduction
The risk of developing cardiovascular disease is higher for women who had hypertensive
disorders of pregnancy than for women without a history of hypertensive disorders
of pregnancy. However, it is unknown whether the emergency department visits and hospitalization
differ between women with a history of hypertensive disorders of pregnancy and women
without hypertensive disorders of pregnancy. The objective of this study was to characterize
and compare cardiovascular disease−related emergency department visits, hospitalization
rates, and diagnoses in women with a history of hypertensive disorders of pregnancy
with those in women without.
Method
This study included participants from the California Teachers Study (N=58,718) with
a history of pregnancy and data from 1995 through 2020. Incidence of cardiovascular
disease−related emergency department visits and hospitalizations based on linkages
with hospital records were modeled using multivariable negative binomial regression.
Data were analyzed in 2022.
Results
A total of 5% of the women had a history of hypertensive disorders of pregnancy (5.4%,
95% CI=5.2%, 5.6). A total of 31% of women had 1 or more cardiovascular disease−related
emergency department visits (30.9%), and 30.1% had 1 or more hospitalizations. The
incidence of cardiovascular disease−related emergency department visits (adjusted
incident rate ratio=8.96, p<0.001) and hospitalizations (adjusted incident rate ratio=8.88, p<0.001) were significantly higher for women with hypertensive disorders of pregnancy
than for those without, adjusting for other related characteristics of the women.
Conclusions
History of hypertensive disorders of pregnancy is associated with higher cardiovascular
disease−related emergency department visits and hospitalizations. These findings underscore
the potential burden on women and the healthcare system of managing complications
associated with hypertensive disorders of pregnancy. Evaluating and managing cardiovascular
disease risk factors in women with a history of hypertensive disorders of pregnancy
is necessary to avoid cardiovascular disease−related emergency department visits and
hospitalizations in this group.
