ABSTRACT
OBJECTIVE:
We have previously established that a logistic regression model, based on maternal demographic characteristics and blood pressure measured at 11-13 weeks' gestation, can identify about 70% of women who develop future chronic hypertension (CH) in the 3 years following pregnancy, at a screen-positive rate of 10%. Furthermore, in midgestation, women who subsequently develop hypertensive disorders of pregnancy (HDP) have increased peripheral vascular resistance and mild cardiac functional and morphological alterations and these cardiovascular abnormalities persist for at least 2 years after delivery. In this study, we set out to examine whether use of the first-trimester risk model for subsequent development of CH can help to identify women at high risk for cardiovascular maladaptation in midgestation.METHODS:
This was a prospective observational study of 3812 women with singleton pregnancy attending for a routine hospital visit at 11 + 0 to 13 + 6 weeks' gestation and again at 19 + 1 to 23 + 3 weeks at King's College Hospital, London, UK, between December 2019 and August 2020. The first-trimester visit included recording of maternal demographic characteristics and medical history and measurement of systolic and diastolic blood pressure. In midgestation, detailed maternal cardiovascular assessment was carried out. The association between risk for development of CH, determined from first-trimester assessment, and cardiovascular indices in midgestation was examined.RESULTS:
Women who were at high risk for development of future CH, compared to those at low risk, had a higher incidence of HDP. In addition, high-risk women had reduced systolic and diastolic function in midgestation. Among women with HDP, those who were at high risk for future CH, compared to those at low risk, had worse cardiac function in midgestation.CONCLUSIONS:
Use of a model for first-trimester prediction of subsequent development of CH can identify women who show evidence of cardiac maladaptation in midgestation. Further studies are needed to clarify whether women who screen as high risk for future CH, compared to those at low risk, have reduced cardiac function beyond pregnancy. © 2024 International Society of Ultrasound in Obstetrics and Gynecology.Palabras clave
