[Magnetic resonance imaging in non-Q wave infarction].
The aim of this study is to evaluate magnetic resonance (MR) as a clinical tool to identify the site of non-Q myocardial infarction, when other techniques are inadequate. Ten patients underwent MR examination 3 - 15 days after the onset of symptoms. The examinations were performed with a General Electric 1.5 Tesla II unit, by means of ECG-gated MR imaging. The 10 patients were 35 to 56 years of age, 9 were men. In 5 patients it was the first myocardial infarction, in 5 patients the second. MR allowed us to identify the site of myocardial infarction: 5 inferior, 1 posterior, 2 postero-inferior, 1 apical, 2 subendocardial. Thus the MR examination is suggested in non-Q myocardial infarction to detect the site and the extent of the infarct. The MR is useful when echocardiography is technically non adequate or when it is not possible to identify regional wall motion abnormalities. We suggest to use this technique in patients with coronary artery bypass and in patients with multiple infarctions.
