Abstract
- Background: There is little information available on long-term changes in left ventricular function and infarct size after acute myocardial infarction treated with primary angioplasty.<br />Material and Methods: From 1996 to 1998, 100 consecutive patients were treated with primary angioplasty for acute ST-elevation myocardial infarction. Left ventricular ejection fraction was determined by radionuclide ventriculography before discharge, after six weeks and after a mean follow-up time of 20 months (range 11-37). Infarct size was assessed by technetium 99m-tetrofosmin myocardial perfusion tomography (SPECT) at rest, performed at the same time intervals.<br />Results: Mean ejection fraction was 56% at discharge, 55% after six weeks and 57% after 20 months of follow-up. A mean perfusion defect of 19% was measured by SPECT after one week. After six weeks and 20 months of follow-up, the mean perfusion defects were reduced to 14% (p < 0.001) and 15%, respectively.<br />Interpretation: Left ventricular function was well preserved and infarct sizes small to moderate 20 months (range 11-37) after primary angioplasty for acute myocardial infarction, demonstrating that the initial successful effect of the treatment was maintained.
