Pregnancy and subsequent pregnancy outcomes in peripartum cardiomyopathy.
OBJECTIVE
To study the clinical profile and management of peripartum cardiomyopathy, and to analyze the pregnancy outcomes of pregnant women with this disorder as well as its effect on subsequent pregnancies.


METHODS
All patients admitted with peripartum cardiomyopathy from July 2006 to June 2009 by the Departments of Cardiology and Obstetrics and Gynecology from the Institute of Post Graduate Medical Education and Research, Kolkata, India, were considered for this observational study. Thirty-six women with 42 pregnancies (36 first pregnancies and six second pregnancies in the same patients) were evaluated.


RESULTS
Primiparas constituted 39% (14/36) of the total study population. Twenty-six women (72%) were clinically improved and in 17 (48%) the left ventricular functional status returned to normal. Five cases (14%) developed persistent cardiomyopathy (persistent left ventricular dysfunction beyond six months of presentation), and five women (14%) presented with thromboembolic events and anticoagulation was used as secondary prophylaxis. Maternal mortality was 14% (5/36). Among all live babies two had intrauterine growth restriction (IUGR) and another two died during the neonatal period. Of the six women with subsequent pregnancies, the patient with persistent cardiomyopathy died after delivering a stillborn baby. The remaining five cases with normal left ventricular functional status had favorable fetal outcomes; however, the mothers experienced morbidities such as symptoms of heart failure (two cases) and one of them progressed to persistent cardiomyopathy.


CONCLUSIONS
Subsequent pregnancies should be discouraged as it increases the risk of recurrence of left ventricular dysfunction. Anticoagulation may be considered as a primary prevention of thromboembolism in pregnant mothers with peripartum cardiomyopathy.
