ABSTRACT
Objective:
To analyze the changes in cardiac structure and function in women with different types of hypertensive disorders in pregnancy (HDP) and explore their influencing factors.Methods:
A total of 1 967 pregnant women diagnosed with HDP who delivered at Peking University Third Hospital from January 1, 2014 to April 15, 2022 were included in the study. They were categorized into four groups based on specific HDP diagnoses gestational hypertension (506 cases, 25.7%), pre-eclampsia (589 cases, 29.9%), pregnancy complicated with chronic hypertension (332 cases, 16.9%) and chronic hypertension with pre-eclampsia (540 cases, 27.5%). Differences in cardiac structure and function among four groups were retrospectively analyzed. Cardiac structure indicators included left atrial diameter (LAD), left atrial area (LAA), right atrial area (RAA), left ventricular end-diastolic diameter (LVEDD), interventricular septal thickness (IVST), left ventricular posterior wall thickness (LVPWT), systolic function indicators included left ventricular ejection fraction (LVEF), lateral systolic mitral annular velocity (Sm), diastolic function indicators included peak early diastolic mitral in flow velocity (E)/peak late diastolic mitral in flow velocity (A), and E/peak early diastolic myocardial velocity of the lateral mitral annulus early diastolic velocity (Em). Influencing factors on cardiac structure and function were analyzed using generalized linear regression. Influencing factors were assessed by generalized linear regression.Results:
(1) General clinical data the differences in age, gestational week at delivery, blood pressure, proportion of diabetes, and length of hospital stay were statistically significant among four different HDP types (all P<0.05). (2) Compared with pregnant women with pregnancy complicated with chronic hypertension, pre-eclampsia, and gestational hypertension, those with chronic hypertension with pre-eclampsia had larger LAD, LAA, RAA and LVEDD (all P<0.001), thicker IVST and LVPWT (all P<0.001), and reduced left ventricular diastolic function (E/A, lateral Em, E/Em) and systolic function (lateral Sm; all P<0.001). Pregnant women with gestational hypertension had the least changes in cardiac structure and function. Compared with pregnant women with pre-eclampsia, those with pregnancy complicated with chronic hypertension had smaller RAA (P<0.001) and lower E/A (P<0.001), with no significant difference in other indicators (all P>0.05). (3) Chronic hypertension with pre-eclampsia, pregnancy complicated with chronic hypertension, and pre-eclampsia were associated with larger LAD, LAA, and LVEDD, and lower lateral Em (all P<0.05).Conclusions:
Different types of HDP are associated with distinct changes in cardiac structure and function. Chronic hypertension with pre-eclampsia demonstrates the most pronounced alterations, followed by pre-eclampsia and pregnancy complicated with chronic hypertension, and gestational hypertension showed the least changes.
