What the study found

The study found that several echocardiographic measurements differed between women with favorable and adverse pregnancy outcomes. The authors report that a combined model of multiple echocardiographic variables had excellent predictive performance for adverse outcomes in women aged 35 years or older with pregnancy-induced hypertension syndrome.

Why the authors say this matters

The authors suggest that multi-parameter echocardiographic assessment may offer a reliable, non-invasive way to identify high-risk patients with pregnancy-induced hypertension syndrome. They conclude that this could support closer monitoring and timely intervention to improve maternal and fetal prognosis.

What the researchers tested

This retrospective study included 240 women aged 35 years or older diagnosed with pregnancy-induced hypertension syndrome from February 2019 to June 2022. The researchers compared echocardiographic indicators, including ejection fraction, stroke volume, cardiac output, E/A ratio, early diastolic mitral annular velocity (E′), E/E′ ratio, left atrial volume index, pulmonary venous flow velocities, and Tei index, between a favorable outcome group and an adverse outcome group.

What worked and what didn't

Women with adverse outcomes had lower ejection fraction, stroke volume, cardiac output, E/A ratio, and E′, and higher E/E′, left atrial volume index, Ar-wave velocity, and Tei index, with lower S- and D-wave velocities; all of these differences were reported as statistically significant. A history of hypertension, nephritis, and family history of hypertension were also identified as significant clinical risk factors, and multivariable logistic regression found both clinical and echocardiographic parameters independently associated with poor outcomes. Receiver operating characteristic analysis showed AUC values of 0.78–0.90 for key indices, and a combined model reached an AUC of 0.925.

What to keep in mind

The summary describes a retrospective study, so the available text does not establish causation. The abstract does not provide detailed information on how outcomes were defined, and limitations are not otherwise described in the available summary.

Key points

  • The study included 240 women aged 35 years or older with pregnancy-induced hypertension syndrome.
  • Adverse pregnancy outcomes were linked to lower EF, SV, CO, E/A ratio, and E′.
  • Adverse outcomes were linked to higher E/E′, LAVI, Ar-wave velocity, and Tei index.
  • A combined echocardiographic model achieved an AUC of 0.925.
  • History of hypertension, nephritis, and family history of hypertension were significant clinical risk factors.
