Acute myocardial infarction: diagnostic and prognostic applications of two-dimensional echocardiography

RA Kloner and AF Parisi

Now that we are entering an era when thrombolytic therapy and early invasive interventions appear to offer significant myocardium-sparing effects, it is important to attempt to exploit techniques that bear directly on the issue of anatomy to obtain an objective measure of infarct size and prognosis. Traditional tests for AMI were developed as diagnostic measures and cannot be expected to measure up to issues raised by modern therapy. Despite its pitfalls, echocardiography can be applied prognostically during the first few hours of AMI evolution to far more patients than can any other imaging technique. We believe that an adequate echocardiographic examination can be an important adjunct that should be used in the early risk assessment of any patient with AMI. Those patients with the greatest potential reversible myocardial damage are clearly the best candidates for aggressive interventions, particularly thrombolysis. For patients with small or no detectable regional wall motion abnormalities, a more conservative initial approach is in order.
