| Popis: | Peripartum cardiomyopathy (PPCM) is a poorly understood, rare disorder in which left ventricular systolic dysfunction and symptoms of heart failure occur between the last month of pregnancy and the first 5 months postpartum. Recent data suggest that uncontrolled oxidative stress leads to the activation of the prolactin cleaving enzyme cathepsin D that in turn leads to an increase in a cleaved 16 kDa prolactin. This cleaved form that has an angiostatic and proapoptotic role appears to drive the disease by adversely impacting the endothelium and cardiomyocyte. Bromocriptine that reduces the prolactin production by dopamine agonist actions may improve outcomes in patients with peripartum cardiomyopathy by eliminating the cleaved form of prolactin despite the activation of the cleaving enzyme. In limited case reports and proof of concept studies use of bromocriptine in the early stages has been shown to improve outcomes in patients with peripartum cardiomyopathy. However, larger randomized control study is still awaited. |
