Eclampsia and early readmission for cardiovascular disease

Area of Science:

• Obstetrics and Gynecology
• Cardiology
• Public Health

Background:

• Pre-eclampsia is a known risk factor for long-term cardiovascular disease (CVD).
• Limited data exists on CVD risk specifically for patients with eclampsia, particularly in the postpartum period.

Purpose of the Study:

• To investigate the risk of readmission for cardiovascular disease (CVD) within one year after delivery in patients diagnosed with eclampsia.

Main Methods:

• Analysis of the Nationwide Readmissions Database (2010-2018).
• Identification of CVD readmissions in the year following delivery for patients with eclampsia.
• Calculation of prevalence rates and confounder-adjusted hazard ratios (HR) for CVD readmission.

Main Results:

• Eclampsia occurred in 74.7 per 100,000 deliveries.
• CVD readmission rates were 854 per 100,000 for eclampsia patients vs. 147 per 100,000 for normotensive patients.
• Eclampsia significantly increased CVD readmission risk (HR 6.9), with particularly high risks for stroke (HR 12.6).

Conclusions:

• Eclampsia is associated with a substantially elevated risk of cardiovascular complications postpartum.
• This increased risk is evident even within the first month after delivery.
• Targeted short-term CVD follow-up is crucial for patients experiencing eclampsia.
