Concentric Cardiac Remodeling and Hypertrophy in Pregnant Individuals with Chronic Hypertension.

This study aimed to evaluate rates of superimposed preeclampsia in pregnant individuals with echocardiography-diagnosed cardiac geometric changes in the setting of chronic hypertension. This was a retrospective study of pregnant individuals with chronic hypertension who delivered singleton pregnancies at 20 weeks' gestation or greater at a tertiary care center. Analyses were limited to individuals who had an echocardiogram during any trimester. Cardiac changes were categorized as normal morphology, concentric remodeling, eccentric hypertrophy, and concentric hypertrophy according to the American Society of Echocardiography guidelines. Our primary outcome was early-onset superimposed preeclampsia defined as delivery at less than 34 weeks' gestation. Other secondary outcomes were also examined. Adjusted odds ratios (aORs) with 95% confidence intervals (95% CIs) were calculated, controlling for prespecified covariates. Of the 168 individuals who delivered from 2010 to 2020, 57 (33.9%) had normal morphology, 54 (32.1%) had concentric remodeling, 9 (5.4%) had eccentric hypertrophy, and 48 (28.6%) had concentric hypertrophy. Non-Hispanic black individuals presented over 76% of the cohort. Rates of the primary outcome in individuals with normal morphology, concentric remodeling, eccentric hypertrophy, and concentric hypertrophy were 15.8, 37.0, 22.2, and 41.7%, respectively ( Concentric remodeling and concentric hypertrophy were associated with increased odds of early-onset superimposed preeclampsia. · Concentric remodeling and concentric hypertrophy were associated with an increased risk of superimposed preeclampsia.. · Concentric hypertrophy was associated with an increased risk of delivery at less than 34 weeks.. · Two-thirds of the individuals in our study had concentric hypertrophy and concentric remodeling..
