Objective: To ascertain the significance of coexisting pulmonary hyper
tension in cardiac disease in pregnancy. Methods: Over a 3-year period
a group of pregnant women with cardiac disease was followed until 6 w
eeks postpartum. Twenty women with pulmonary hypertension were compare
d with 20 controls without pulmonary hypertension with particular refe
rence to maternal and fetal outcome. Analysis of data was carried out
using Fisher's exact test and Student's t-test. Results: Except for Ei
senmenger's syndrome, there were no differences in maternal morbidity
and mortality between the two groups. There were more low birth weight
babies but no significant differences in premature delivery rate, mod
e of delivery or perinatal mortality. Conclusion: Except for Eisenmeng
er's syndrome, coexisting pulmonary hypertension complicating cardiac
disease in pregnancy generally has a favorable outcome for both mother
and fetus.
