Why the study?
Does pregnancy cause permanent change in the degree of heart disease in patients with pre-existing heart disease?
Does pregnancy cause permanent change in the degree of heart disease in patients with pre-existing heart disease?
Pregnancy in women with pre-existing heart disease may cause temporary decreases in functional capacity but does not appear to cause permanent worsening of the underlying cardiac condition.

Supports reassurance in pre-pregnancy counseling for women with heart disease; leaves open confirmation in larger prospective cohorts.
One hundred and six patients have been restudied three and one-half to 5 years (average 4.1 years) after they were observed with pregnancy and heart disease at the Boston Lying-in Hospital. This re-evaluation indicated that the altered circulatory dynamics of pregnancy may temporarily decrease functional capacity. However, no permanent change in degree of heart disease could be directly attributed to the pregnancy for which these patients were followed in 1950 and 1951.
