[Scintigraphy of the myocardium in postinfarct cardiac fibrosis]

The authors conducted a scintigraphic study of 50 patients with a 2-7 year history of myocardial infarction and clinical findings of postinfarction myocardiofibrosis. 201Tl-chloride with the activity of 74 MBq and the Picker 500 magna-scanner (USA) were employed. Four projections were used in the study. It was stressed that in anterior myocardial infarction the best positions were the front and front-left-oblique ones (30 and 45 degrees) and in posterior myocardial infarction the front-left-oblique one (75 degrees). A conclusion has been made as to a high sensitivity of the method to confirm postinfarction myocardiofibrosis represented in the form of a zone with disturbed perfusion. The authors underlined a high value of the method in cases accompanied by conductive disorders as the information value of a scintigram exceeded that of ECG.
