| Abstract: | Myocardial scintigraphy with pyrophosphate-99mTc-Sn was used as a diagnostic test in 23 patients with different disorders of rhythm and intracardia conduction who were admitted to the department of emergency cardiology of the All-Union Cardiological Scientific Center, Academy of Medical Sciences of the USSR with suspected acute myocardial infarction. Scintigrams were positive in 11 of 12 patients with acute myocardial infarction who were examined in periods of 6 hours of 10 days. One patient examined on the 13th day of the disease had negative scintigrams. In 6 of 11 patients with myocardial infarction not confirmed, the scintigrams were also negative, in 3 other patients positive scintigrams were due to a postinfarction aneurysm. The authors conclude that myocardial scintigraphy with pyrophosphate-99mTc-Sn is an adequate test in the diagnosis of acute myocardial infarction, especially in the examination of patients with disorders of intracardiac conduction. |
