The effect of myocardial reperfusion on regional left ventricular function has been quantitated by analysis of segmental wall motion in 185 patients enrolled in a randomized trial comparing thrombolysis with conventional treatment in patients with acute myocardial infarction. When analyzing the hemodynamic data on an "intention to treat" basis we found a significant preservation of left ventricular function after thrombolytic therapy when compared to conventional treatment. In addition, the wall motion analysis showed that a significant improvement of regional function in the "infarct zone" was observed in inferior infarction as well as in anterior infarction, although significant changes in regional function of the remote "non infarct zone" were observed at the acute as well as at the chronic stage. However, our follow-up data indicate that as yet it has not been resolved whether this method of treatment does indeed improve prognosis in patients with acute myocardial infarction. Accordingly, we maintain the view that such invasive treatment should not be generally applied until more follow-up data become available from larger randomized trials.
