title: Risk factors for maternal outcome in pregnancy complicated with dilated cardiomyopathy.
abstract: OBJECTIVE
  The goal of the study was to determine risk factors for maternal cardiac failure in pregnancy complicated with dilated cardiomyopathy (DCM).
  
  
  METHODS
  The subjects were 29 patients diagnosed with DCM before conception or during the first 7 months of pregnancy. DCM was defined as left ventricle end-diastolic dimension (LVDd)≥48 mm and/or fractional shortening (%FS)≤30% on echocardiography. Patients were followed until at least 1 year after delivery and were categorized into a poor prognosis group (n=6; death or end stage heart failure of New York Heart Association (NYHA) class III and IV) and a good prognosis group (n=23; all other cases).
  
  
  RESULTS
  DCM was initially diagnosed during pregnancy in 6/6 and 8/23 patients in the poor and good prognosis groups, respectively (P<0.005). The %FS of the first test during pregnancy was 17.5±6.2 and 27.4±9.3% in the respective groups (P<0.005). In eight abortion cases with %FS 15.2±3.1%, %FS, cardiac function and NYHA class were maintained until 20 months after abortion. There was no relationship between LVDd and maternal outcome.
  
  
  CONCLUSIONS
  Onset during pregnancy and decreased %FS are risk factors for a poor maternal outcome in patients with DCM. Abortion prevents further deterioration of cardiac function in patients with a very low %FS.
