[Scanographic picture of the lungs in acute myocardial infarct]

Lung scanning with MAA-131I was used to detect early "subclinical" stages of cardiac insufficiency in 51 patients suffering from primary myocardial infarction with different extent of involvement of the heart muscle. The contribution to the blood flow of the right lung was found to be rather greater than that of the left lung, and the contribution of the upper parts of the lungs greater than that of the lower parts. It was eatablished that the severity and stability of changes in pulmonary blood flow were in accordance with the extent of left ventricular involvement. The diagnostic value of MAA-131I scanning in identifying early stages of cardiac insufficiency and reorganization of pulmonary blood flow in patients with myocardial infarction for the choice of rational therapy and for prognostication is shown.
