title: Results of a long-term training program after acute myocardial infarction.
abstract: BACKGROUND
  It is not well known what should be the benefits of a prolonged physical rehabilitation program after an acute myocardial infarction.
  
  
  METHODS
  Our study is an open, randomized comparison of a long-term versus a standard rehabilitation program. Sixty-seven patients with acute myocardial infarction were included in an outpatient physical rehabilitation program of 6-8 weeks. Of these, 22 randomly selected patients continued the program until the 36th month (Group A). Twenty-five of the others were rechecked after 36 months, and represented the controls (Group B). For both groups, at the end of this period, a cycloergometer exercise test evaluated the exercise capacity of subjects and an echocardiogram was performed to determine left ventricular systolic and diastolic function.
  
  
  RESULTS
  The maximal exercise capacity increased from 147 +/- 13.8 W to 178 +/- 16.4 W in Group A (p < 0.01), but it decreased from 144 +/- 13.2 to 132 +/- 12.8 W in group B. Functional aerobic impairment decreased from 29 +/- 2.7% to 22 +/- 2.1% in Group A, but it increased from 26 +/- 2.5% to 37 +/- 3.8% in Group B. The ejection fraction and diastolic function parameters were not significantly modified during the 36 months, for both groups.
  
  
  CONCLUSIONS
  Long-term physical rehabilitation is useful in patients after an acute myocardial infarction to increase effort capacity, but left ventricular performance is not significantly changed.
