Update on Peripartum Cardiomyopathy

Although multiple mechanisms have been postulated, peripartum cardiomyopathy (PPCM) continues to be a cardiomyopathy of unknown cause. Multiple risk factors exist and the clinical presentation does not allow differentiation among potential causes. Although specific diagnostic criteria exist, PPCM remains a diagnosis of exclusion. Treatment modalities are dictated by the clinical state of the patient, and prognosis is dependent on recovery of function. Randomized controlled trials of novel therapies, such as bromocriptine, are needed to establish better treatment regimens to decrease morbidity and mortality. The creation of an international registry will be an important step to better define and treat PPCM. This article discusses the pathogenesis, risk factors, diagnosis, management, and prognosis of this condition.
