Pre-eclampsia: an important risk factor for asymptomatic heart failure

Area of Science:

• Cardiology
• Obstetrics
• Public Health

Background:

• Pre-eclampsia (PE) is linked to postpartum heart disease and cardiovascular (CV) risk factors.
• Asymptomatic cardiac abnormalities, classified as heart failure Stage B (HF-B), are a concern postpartum.

Purpose of the Study:

• To determine if PE independently associates with postpartum asymptomatic cardiac abnormalities.
• To assess the impact of conventional CV risk factors on this association.

Main Methods:

• A cross-sectional cohort study comparing 107 formerly pre-eclamptic women with 41 controls 4-10 years postpartum.
• Cardiovascular risk assessment included cardiac ultrasound, blood pressure, and metabolic syndrome evaluation.
• Regression analyses were used to identify associations between PE, risk factors, and HF-B.

Main Results:

• Asymptomatic HF-B was 3.5 times more prevalent in the PE group (25% vs 7%).
• PE remained significantly associated with HF-B after adjusting for postpartum interval, hypertension, and HDL (aOR 4.4).
• Prehypertension was significantly associated with HF-B in formerly pre-eclamptic women (OR 4.3), but metabolic syndrome determinants were not.

Conclusions:

• PE is independently associated with a four-fold increased risk of asymptomatic cardiac abnormalities in women.
• Prehypertension exacerbates this risk, highlighting its importance in postpartum follow-up.
• Metabolic syndrome determinants did not show a significant association with HF-B in this cohort.
