Cardiac Effects in Children of Hypertensive Mothers: A Literature Review

Area of Science:

• Cardiovascular Science
• Perinatal Medicine
• Developmental Biology

Background:

• Preeclampsia (PE) affects up to 8% of pregnancies, causing hypertension.
• In utero PE exposure is linked to cardiac changes in neonates, such as increased left ventricular mass and myocardial hypertrophy.
• Long-term cardiovascular effects in offspring are inconsistent, but some studies suggest persistent systolic and diastolic dysfunction into adulthood.

Purpose of the Study:

• To review the cardiac manifestations in offspring exposed to preeclampsia in utero.
• To highlight knowledge gaps regarding molecular pathways linking PE to offspring cardiovascular outcomes.
• To increase awareness for early intervention opportunities in this high-risk population.

Main Methods:

• Literature review synthesizing existing research on PE and offspring cardiovascular health.
• Analysis of studies investigating fetal developmental programming due to intrauterine conditions.
• Examination of evidence linking PE to altered cardiac remodeling and vascular resistance, independent of fetal growth restriction.

Main Results:

• Offspring exposed to PE exhibit cardiac structural and functional changes, including increased left ventricular mass and hypertrophy.
• Evidence suggests a potential for long-term cardiovascular risks, such as systolic and diastolic dysfunction, persisting into adolescence and adulthood.
• Mechanisms involved in PE's impact on offspring cardiovascular health include placental insufficiency, angiogenic imbalance, oxidative stress, and epigenetic modifications.

Conclusions:

• Preeclampsia exposure during pregnancy significantly impacts offspring cardiovascular development.
• Further research is crucial to elucidate the molecular pathways and long-term consequences.
• Early detection and intervention strategies are needed for infants born to mothers with preeclampsia.
