Why the study?
Does technetium 99m pyrophosphate myocardial scintigraphy improve the diagnosis of perioperative myocardial infarction in revascularized patients?
Does technetium 99m pyrophosphate myocardial scintigraphy improve the diagnosis of perioperative myocardial infarction in revascularized patients?
Radionuclide infarct scintigraphy serves as a useful adjunct to electrocardiography in diagnosing perioperative myocardial infarction after revascularization, whereas CPK-MB is frequently elevated without other evidence of infarction.
No takes yet. Share an insight, caveat, or question.
Scintigraphy may complement ECG for perioperative MI diagnosis after revascularization; leaves open its added value versus enzyme elevation alone.
Klausner et al. (1977) studied this question.
