88例因不同病因的胸痛而入住冠心病监护室，但没有急性透壁性心肌梗死的心电图证据的患者使用锝-99 m焦磷酸锡（99 m-Tc-PYP）进行了心肌显像。其中17例患者的心电图和酶学证据提示急性内膜下心肌梗死。在这些患者中，放射性造影均为阳性，显示99 m-Tc-PYP摄取增加，呈微弱但弥漫性阳性或局部强阳性。其余71例患者未出现急性心肌梗死的ECG或酶证据。在这些患者中，心肌血流图均为阴性。因此，99 m-Tc-PYP心肌显像能鉴别急性内膜下心肌梗塞。利用这项技术可以识别出心内膜下心肌梗死的绝对频率，将来必须在更多的患者中建立。
Eighty-eight patients admitted to a coronary care unit with chest pain of varying etiology but without ECG evidence of an acute transmural myocardial infarction had myocardial scintigrams using technetium-99m stannour pyrophosphate (99m-Tc-PYP). Seventeen of these patients had ECG and enzymatic evidence suggestive of acute subendocardial myocardial infarction. In each of these the scintigrams were postivie demonstrating increased 99m-Tc-PYP uptake either in a faintly but diffusely positive pattern or in a well-localized strongly positive one. The remaining 71 patients did not evolve ECG or enzymatic evidence of acute myocardial infarction. In each of these patients the myocardial scintigram was negative. Thus 99m-Tc-PYP myocardial scintigrams are capable of identifying the presence of acute subendocardial myocardial infarction in patients. The absolute frequency with shich subendocardial myocardial infarction can be recognized utilizing this technique will have to be established in a larger number of patients in the future.
