Maternal Cardiac Function after Normal Delivery, Preeclampsia, and Eclampsia: A Prospective Study

Area of Science:

• Cardiology
• Obstetrics
• Maternal-Fetal Medicine

Background:

• Preeclampsia (PE) and eclampsia (E) are serious hypertensive disorders of pregnancy.
• Maternal cardiac function and hemodynamics can be affected postpartum.

Purpose of the Study:

• To assess maternal cardiac function in the postpartum period up to 6 months in women with preeclampsia and eclampsia.
• To evaluate hemodynamic changes and peripheral vascular resistance.

Main Methods:

• Prospective study of 90 postpartum women with PE/E and 55 controls.
• Maternal hemodynamics and cardiac parameters recorded at multiple time points: postpartum days 1, 3, 5, 9, 14, and at 2 and 6 months.

Main Results:

• PE is associated with elevated systemic vascular resistance (SVR), persisting up to 6 months in severe cases.
• Cardiac contractility parameters (e.g., ESV, SV, CO) were significantly decreased postpartum.
• Reduced cardiac function and elevated SVR suggest asymptomatic heart failure in severe PE/E.

Conclusions:

• Postpartum hemodynamics in PE/E are characterized by impaired myocardial contractility and increased peripheral resistance.
• The severity of cardiac and vascular changes correlates with the severity of hypertensive disorders during pregnancy.
