[Comparative studies of the diagnosis of acute myocardial ischemia using radioisotopes]. / Vergleichende Untersuchungen zur Diagnostik der akuten Myokardischämie mit Radioisotopen.

It is reported on 152 patients with ischaemic heart disease who were examined with technetium-99m-diphosphonate. For clearing up the diagnosis of an acute myocardial infarction the findings of 23 patients with acute myocardial infarction in the course of the disease were compared with clinical and paraclinical parameters such as ECG, ferments and echocardiogram. In these cases could be stated: the Tc-99m-diphosphonate-scintigraphy is a sensitive indicator for a myocardial disease, but is not specific for the diagnosis of an acute myocardial infarction. Other clinical and paraclinical parameters cannot be substituted by the scintigraphy. It contributes to the judgment of the prognosis after an acute myocardial infarction and refers to possible disturbances of the kinetics of the wall. In the acute phase in a clinically ascertained infarction the examination can be renounced.
