Severe Preeclampsia is Associated with Functional and Structural Cardiac Alterations: A Case-control Study.

Area of Science:

• Cardiology
• Obstetrics
• Perinatology

Background:

• Severe preeclampsia (PE) poses significant risks to maternal and fetal health.
• Cardiac function and structure can be affected by hypertensive disorders of pregnancy.

Purpose of the Study:

• To compare electrocardiographic and echocardiographic findings in severe preeclampsia versus uncomplicated pregnancies.
• To identify cardiac alterations associated with severe preeclampsia.

Main Methods:

• A prospective, case-controlled study.
• Inclusion of 21 pregnant women with severe PE and 24 matched healthy pregnant controls.
• All participants underwent electrocardiographic and echocardiographic assessments.

Main Results:

• Patients with severe PE exhibited shorter QRS intervals and longer PR intervals compared to controls.
• Significant increases in left ventricular end-systolic diameter, posterior wall thickness, left ventricular mass, and relative wall thickness were observed in the PE group.
• Early-onset severe PE was associated with larger left ventricular end-diastolic diameter and volume.

Conclusions:

• Detected structural cardiac changes in severe PE suggest a chronic process.
• Diastolic dysfunction and left ventricular remodeling are more pronounced in severe early-onset PE.
• These findings highlight the cardiac impact of severe preeclampsia.
