Randomized Evaluation of Bromocriptine in Myocardial Recovery Therapy (REBIRTH) for Peripartum Cardiomyopathy

The study will enroll 200 women newly diagnosed with peripartum cardiomyopathy within 5 months postpartum in a randomized placebo controlled trial of bromocriptine therapy to evaluate its impact on myocardial recovery and clinical outcomes. Given that bromocriptine prevents breastfeeding, an additional 50 women with peripartum cardiomyopathy excluded from the trial due to a desire to continue breastfeeding but meeting all other entry criteria will be followed in an observational cohort.

All women will have an assessment of LVEF demonstrating an LVEF < or = 0.35 within 4 weeks prior to consent. At entry they will then have an assessment of LVEF by echocardiogram which will be repeated at 6- and 12-months post study entry. Subjects in the randomized trial will be randomized to standard medical therapy for heart failure plus placebo or standard therapy plus 8 weeks of bromocriptine (2.5 mg twice daily for 2 weeks then once 2.5 mg daily for 6 weeks). Women receiving bromocriptine not currently on anticoagulation will also receive prophylactic anticoagulation with rivaroxaban 10 mg once daily for 8 weeks.
