The study is being done to test the use of a drug called bromocriptine for women who have a condition called Peripartum cardiomyopathy or PPCM. PPCM means you have a weak heart after giving birth. The study will look at how the heart muscle improves in women taking bromocriptine compared to a group of women given a placebo or inactive pill. Bromocriptine is approved by the United States Food and Drug Administration (FDA) to treat irregular periods and other symptoms that result from having high blood levels of a substance called prolactin. It is not approved for use in usual care to treat PPCM. The follow up period will be about 3 years. The study will have an initial visit and then the follow -up visits will take place at one, three, six, and 12 months in the first year and visits by phone at 24 months and 36 months.
