title: [Prognostic value of stress echocardiography by dobutamine combined with atropine].
abstract: OBJECTIVE
  To determine the prognostic value of dobutamine-atropine stress echocardiography (DASE).
  
  
  METHODS
  We studied 452 consecutive patients at high risk for coronary artery disease, using DASE. They were followed during a mean period of 23 months.
  
  
  RESULTS
  There were 9 cardiac deaths and 2 acute myocardial infarctions in the group of patients with positive tests, and there were 2 myocardial infarctions and 1 cardiac death in patients with negative DASE.
  
  
  CONCLUSIONS
  We conclude that DASE reliably identifies patients at high risk for hard cardiac events.
