title: [Combined use of bicycle ergometry test and echo-dipyridamole in stratification of risk after thrombolysed myocardial infarct].
abstract: OBJECTIVE
  Verify the value of the combined use of Dipyridamole Stress Echocardiography (DSE) and Exercise Testing (ET) for predicting cardiac events after Thrombolysed Myocardial Infarction (TMI).
  
  
  METHODS
  Prospective, with a medium follow-up of 221 days (range 30-446).
  
  
  METHODS
  Coronary Care Unit with Cardiology Service.
  
  
  METHODS
  32 consecutive patients, 24 men and 8 women, mean age 61 years (range 39-72) with acute myocardial infarction.
  
  
  METHODS
  Systemic thrombolysis with PTPA. DSE and ET in therapeutic wash out 12 +/- 3 days after admission to the Coronary Care Unit.
  
  
  RESULTS
  9 patients had positive ET, 18 patients had negative ET, 5 patients did not perform ET. 19 patients had positive DSE, 13 patients had negative DSE. Patients with positive DSE had in 6 cases (group 1) WMA remote from the infarction area (WMAR), in 13 cases (group 2) WMA appeared in the infarct related area. Cardiac events occurred in 15 patients: 1 cardiovascular death, 1 myocardial re-infarction, 13 cases of unstable angina. 2 patients with negative DSE had cardiac events. All patients in group 1 had events, 1 patient with a previous positive ET, 3 patients with previous negative ET. 2 patients in this group didn't perform ET. 7 patients in group 2 had cardiac events, in all cases with a previous positive ET. 1 single patient in this group with negative ET had events.
  
  
  CONCLUSIONS
  1) Patients without WMA at DSE are at low risk for cardiac events after thrombolysed myocardial infarction. 2) Presence of WMAR appears to be associated with a higher risk, whatever the result of ET may be. 3) Patients without WMAR can be further stratified by ET in therapeutic wash out. High risk patients seem to be those with positive DSE and positive ET. 4) Combined use of DSE and ET seem to allow optimal risk stratification after thrombolysed myocardial infarction.
