title: [Retrospective analysis of 266 cases of pregnancy complicated by heart disease].
abstract: OBJECTIVE
  To investigate the influence of cardiac function of pregnant women on outcome of their pregnancies.
  
  
  METHODS
  Clinical data of 266 cases of pregnant women with heart diseases from January, 1993 to March, 1999 were analyzed retrospectively.
  
  
  RESULTS
  (1) The highest incidence of cardiac disease with grade I to II of heart function was due to myocarditis, sequelae of myocarditis and abnormal cardiac rhythm (179 cases, 67.29%). The incidence of congenital heart disease is on the second (41 cases, 15.41%) which is higher than that of rheumatic heart disease (28 cases, 10.91%). (2) Grade III and IV cardiac function was mainly related to congenital and rheumatic heart diseases during pregnancy. The rate of grade I/II heart function in pregnant women after heart operations was 95.45%. (3) The incidence of premature delivery, low weight of newborns and perinatal mortality of mother were higher in women with grade III and IV heart function than in those with grade I and II heart function.
  
  
  CONCLUSIONS
  The incidence of myocarditis and sequelae of myocarditis is increasing. Pregnancies complicated with congenital and rheumatic heart diseases are still major causes of perinatal morbidity and mortality of mother and baby. Heart operation can obviously improve the heart function. More effective managements should be adopted.
