Improvement in regional and global left ventricular function after intracoronary thrombolysis: assessment with two-dimensional echocardiography.
After acute myocardial infarction, 23 patients undergoing intracoronary thrombolysis and 10 patients receiving conventional medical treatment were studied by 2-dimensional echocardiography to determine changes in regional and global left ventricular (LV) performance. Both quantitative and qualitative analysis of echocardiographic studies showed improvement in regional and global LV function in 18 patients with successful reperfusion immediately after thrombolysis to 10 days later (p less than 0.0005). Eleven patients who were studied before thrombolysis demonstrated no change in regional or global LV function immediately after thrombolysis. LV function did not improve in the conventionally treated group. These data indicate that in patients with acute coronary artery occlusion successfully reperfused by intracoronary thrombolysis, regional and global LV function improved by day 10 but not immediately after reperfusion.
