Background: Women diagnosed with peripartum cardiomyopathy (PPCM) are frequently advised not to breastfeed their infants because of concern that the nursing hormone prolactin drives the pathogenesis of PPCM. However, this remains controversial. We sought to determine whether women with PPCM who breastfed had lower rates of recovery.
Methods: Patients with PPCM at the University of Michigan (2000-2011) were retrospectively reviewed. Demographics, clinical data, and outcomes were collected. Questionnaires requesting information about breastfeeding status and duration were mailed to women with PPCM. This data was correlated with recovery status, defined as left ventricular ejection fraction ≥ 50% at 1 year after diagnosis.
Results: There were 63 patients with PPCM, and 27 with known breastfeeding status. Of the 13 women who breastfed (52%), 8 recovered (62%) and 5 did not (38%), whereas of the 14 women who did not breastfeed, 11 recovered (79%) and 3 did not (21%). This was not statistically different (p=0.29). There were no significant differences between breastfeeding and non-breastfeeding women related to their mean age or treatment with heart failure medications. Of the 16 patients who completed questionnaires, 11 (69%) reported their physician had instructed them not to breastfeed.
Conclusions: There was no significant difference in recovery status among women with PPCM who breastfed. Larger prospective studies are needed to clarify this conclusion. Currently, PPCM patients should not be discouraged from breastfeeding unless other contraindications are present.
