Menstrual patterns in women with congenital heart disease.

To examine the extent to which congenital heart disease (CHD) influences ovarian function, 98 women (mean age 32.7 years) were asked to complete a mailed questionnaire regarding their menstrual patterns. Patients were divided into acyanotic (60%) and cyanotic (38.8%) groups. Cycle lengths, duration of menstrual cycle, regularity of menses, amount of flow, and breakthrough bleeding were compared in these two groups and against age-matched controls. The mean age of menarche for the sample (13.4 years) was significantly different (p < 0.004) when compared to their controls (12.5 years). With the exception of breakthrough bleeding, statistical differences were not found between the study population and the controls. When the menstrual histories of cyanotic women were compared with those of acyanotic women, differences were found for all categories of menstrual patterns with the exception of the amount of menstrual flow. Menstrual patterns of cyanotic women compared to controls were found to be significantly different for all categories with the exception of amount of flow. In general, women with CHD have menstrual patterns similar to those in the general population.
