Insights

Hypertensive disorders of pregnancy (HDP) impact heart structure and function, with superimposed preeclampsia (SPE) showing the most significant echocardiographic changes. Early echocardiography can detect these abnormalities in high-risk pregnancies.

Area of Science:

  • Cardiology
  • Obstetrics
  • Maternal-Fetal Medicine

Background:

  • Hypertensive disorders of pregnancy (HDP) encompass gestational hypertension, preeclampsia (PRE), and chronic hypertension with superimposed preeclampsia (SPE).
  • These conditions pose significant risks to maternal and fetal health.
  • Understanding cardiac implications is crucial for managing HDP.

Purpose of the Study:

  • To retrospectively analyze echocardiographic differences in biventricular structure and function among women with different types of HDP.
  • To compare these findings with normotensive pregnant controls.

Main Methods:

  • Retrospective analysis of echocardiograms from women during or within one year postpartum.
  • Inclusion of 706 subjects (427 cases, 279 controls), categorized into gestational hypertension, PRE, and SPE groups.
  • Exclusion of patients with specific comorbidities like pulmonary embolism, malignancy, autoimmune disease, or structural heart disease.

Main Results:

  • Significant, graded differences in echocardiographic parameters were observed across HDP groups compared to controls.
  • Left ventricular (LV) mass index and E/e' were highest in the SPE group, indicating more profound cardiac remodeling.
  • Abnormalities in LV mass index and diastolic filling (E/e') were most pronounced in SPE and PRE.

Conclusions:

  • Left ventricular remodeling and diastolic dysfunction are prevalent in HDP, particularly in SPE and PRE.
  • Echocardiography during or shortly after pregnancy can identify cardiac abnormalities in high-risk women.
  • Further research is needed to determine the long-term consequences of these echocardiographic findings.
