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.
The study will enroll 200 women newly diagnosed with peripartum cardiomyopathy within 5 months postpartum in a randomized trial of bromocriptine therapy to evaluate its impact on myocardial recovery. All women will have an assessment of LVEF demonstrating an LVEF \< or = 0.40 within 4 weeks prior to consent. The women in the breastfeeding cohort will have a qualifying LVEF \< 0.40 within 8 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 t…
Inclusion Criteria: 1. Presentation with a new diagnosis of peripartum cardiomyopathy 2. Post-delivery and within the first 5 months post-partum. 3. Clinical assessment of an LVEF \< or =0.40 within 4 weeks of consent for randomized control trial 4. Clinical assessment of an LVEF \< or =0.40 within 8 weeks of consent for breastfeeding cohort 5. Age \> or = 18. Exclusion Criteria: 1.

Bromocriptine 2.5 mg one tablet by mouth twice daily for 2 weeks then once daily for 6 weeks. Subjects not on anticoagulation at the time of entry will also receive rivaroxaban 10 mg tablets once daily for 8 weeks while on bromocriptine.
Placebo one tablet by mouth twice daily for 2 weeks then once daily for 6 weeks. Subjects who are not on anticoagulation will not receive rivaroxaban but will receive a second placebo once daily for 8 weeks while on study drug.
GDMT will potentially include angiotensin converting enzyme inhibitors (ACEi), angiotensin II receptor antagonists (ARB), angiotensin receptor blocker-neprilysin inhibitors (ARNI), beta adrenergic receptor antagonists (beta blockers) , Mineralocorticoid receptor antagonists (MRA), sodium-glucose cotransporter-2 inhibitors (SGLT2i),
Subjects not on anticoagulation clinically who are randomized to bromocriptine will receive rivaroxaban 10 mg tablets once tablet by mouth daily for 8 weeks while on bromocriptine.
Subjects not on anticoagulation clinically who are randomized to placebo (rather than bromocriptine) will receive a second placebo one tablet by mouth daily for 8 weeks.
