[Non-invasive assessment of coronary reperfusion].

The patency of the infarct-related coronary artery seems to be an important prognostic factor after an acute myocardial infarction. Coronary angiography has been used until now to assess coronary patency. However, as it is an invasive procedure and its optimal timing after fibrinolytic treatment has not been established, a noninvasive marker is most desirable. There are a number of methods currently used to document coronary reperfusion non-invasively. This review discusses the advantages and disadvantages of the classic non-invasive methods, like resolution of chest pain, reperfusion arrhythmias, normalization of ST segment elevation, and enzymatic determinations. The imaging methods, especially echocardiography but also magnetic resonance imaging, offer interesting possibilities for the future.
