Angiotensin converting enzyme

inhibitors should be avoided in the second and third trimester but are safe to use postpartum. Beta-blockers can be used when not contraindicated during pregnancy, and they can be used postpartum. During pregnancy, β-1 selective agents are preferred because β-2 receptor blockade may have an antitocolytic effect. Inotropic agents should be used in patients with signs of low cardiac output or with persistent congestion despite diuretics/afterload-reducing agents. Anticoagulation is recommended in patients with PPCM as these patients have a high incidence of LV thrombus, Inhibitors,research,lifescience,medical especially patients with an LVEF <35%. Heparin (unfractionated and low-molecular-weight) is favored in pregnancy since, unlike warfarin, it doesn’t cross the placenta. Warfarin should Inhibitors,research,lifescience,medical be avoided as it is teratogenic in early pregnancy and has a risk of causing fetal cerebral hemorrhage in the second and third trimester. After delivery, PPCM should be treated according to current guidelines for heart failure.22 Specific Experimental Treatment Strategies Awaiting Further Validation Immunosuppressive agents: The prevalence of myocarditis in PPCM varies from 9–78%.32, 33 A single nonrandomized study

suggested that immunosuppression Inhibitors,research,lifescience,medical may benefit women with biopsy-proven myocarditis.34 However, the Myocarditis Treatment Trial did not show any benefit of immunosuppressive medications Inhibitors,research,lifescience,medical and, given the risks of immunosuppressive therapy, they are currently not widely utilized.33, 35 Intravenous immune globulin (IVIG): The

role of IVIG in PPCM was evaluated in a retrospective study of six women treated with IVIG and 11 controls treated conventionally.36 After a 6-month follow-up, the absolute increase in LVEF was greater in those treated with IVIG compared to controls Inhibitors,research,lifescience,medical (26% vs. 13%). However, the IMAC trial (Controlled Trial of Intravenous Immune Globulin in Recent-Onset Dilated Cardiomyopathy) showed that despite the potential therapeutic efficacy suggested by previous uncontrolled studies, immune globulin treatment of adult patients with recent-onset http://www.selleckchem.com/products/Adrucil(Fluorouracil).html Cardiomyopathy in this placebo-controlled trial did not affect improvements in LVEF or functional capacity during follow-up.36 Bromocriptine: This treatment strategy is based on an experimental observation of preventing Sodium butyrate PPCM in mice via prolactin blockade with bromocriptine.11 In a randomized open-label study performed in South Africa, 20 women with newly diagnosed PPCM were randomly assigned to receive either standard care plus bromocriptine or standard care alone.37 The 10 women receiving bromocriptine demonstrated significantly greater improvement in LVEF compared to the 10 women receiving standard care only (27% to 58% vs. 27% to 36%). One patient in the bromocriptine group died compared to four in the standard care group.
