PERIPARTUM CARDIOMYOPATHY: A CONDITION PHYSICIAN SHOULD BE AWARE OF!
Abstract
Peripartum cardiomyopathy (PPCM) is a poorly characterized, rare form of cardiomyopathy. The etiology of PPCM is unknown, but viral, autoimmune, and idiopathic causes may contribute (1). Risk factors include multiparity, age>30 years, multiple pregnancies, obesity, hypertension, and toxemia. The presentation is similar to other forms of congestive heart failure. Signs and symptoms of PPCM resemble systolic heart failure, and it is diagnosed by exclusion. The diagnosis of PPCM should not be considered until other causes of cardiac dysfunction are ruled out. Echocardiography is central to diagnosis. An echocardiogram typically reveals an ejection fraction of <45% and/or fractional shortening of <30%, along with a left ventricular end-diastolic dimension>2.7 cm/m2 of body surface area. (2) Treatment consists of diuretics, vasodilators, digoxin. Patients with PPCM are at high risk of thromboembolism, and therefore anticoagulation therapy should be considered.
