Objective: To describe the subsequent reproductive outcome for a Danish nationwide cohort of women with peripartum cardiomyopathy (PPCM).Design: Nationwide historic cohort study.Setting: Secondary and tertiary centres across Denmark.Sample: Women with PPCM.Methods: Sixty-one women with PPCM during 2005-2014 were identified in a nationwide, registry-based study and the diagnosis was validated through audit of patient records. A new search for subsequent reproductive outcome in this cohort from 2005-2016 was conducted in the Danish National Birth Registry and the Danish National Patient Registry. Detailed clinical data were obtained from patient records.Main Outcome Measures: Sterilisations and subsequent reproductive outcomes after PPCM, including all pregnancies, miscarriages, terminations and deliveries.Results: Of 61 women with PPCM, 13 (21%) had a total of 16 subsequent pregnancies resulting in one miscarriage, seven early terminations, one ectopic pregnancy and seven liveborn children. There were no maternal deaths or significant cardiac events during pregnancy, but one woman, who gave birth to a liveborn child, had a relapse of PPCM 7 weeks postpartum. None of the six women who had a first trimester termination, experienced relapse of PPCM. Of the 13 women with a subsequent pregnancy, 62% had prior to this been advised against a new pregnancy due to the risk of recurrent PPCM. A total of four women (6.6%) were sterilised.Conclusion: Peripartum cardiomyopathy affects women's reproduction with few subsequent pregnancies resulting in a liveborn child. The finding of a 1/7 relapse among women with recovered LVEF is in accordance with most previous studies.Tweetable Abstract: Outcome in pregnancies after peripartum cardiomyopathy: results from the first nationwide study.
