Factor Information
Data ID	2318
Factor	cardiac events before pregnancy
Description	The factors found to be significantly predictive for maternal cardiac complications were cardiac events before pregnancy (odds ratio [OR] 36.811), New York Heart Association functional class greater than II (OR 27.702), oxygen saturation below 90% (OR 7.506), and left ventricular obstruction (aorta stenosis) (OR 2.408).
Biomarker	YES
Classification	A3 (clinical factor - disease & symptom)

Association
Application	prognosis
Objective	predictive risk factors for maternal cardiac complications
p Value	<0.001
OR	36.811
Conclusion	Potential risk factors for maternal cardiac complications included cardiac events before pregnancy (heart failure, severe arrhythmia, and cardiac shock); NYHA functional class greater than II; oxygen saturation below 90%; aortic stenosis; pulmonary stenosis; and PAH. Identification of maternal, fetal, and neonatal complications among women with CHD may guide medical intervention and therefore reduce pregnancy-associated risk for these patients.
