方法:68例病人,男67人,女1人,平均年龄57.9岁。68例都有典型的病史,心电图改变和血清酶的异常而确诊为急性心肌梗塞。其中急性穿透性梗塞52例,急性心内膜下梗塞16例。用20毫居里~(99m)锝-亚锡-焦磷酸盐静脉注射,静注后两小时,以前位,45°左前斜位,左侧位进行γ闪烁照像得到心肌闪烁图。 68例病人在急性心肌梗塞症状发作之后3.0±1.1天,进行急性期的心肌闪烁照像;19个病人在出院前,即梗塞后12.6±2.8天,做第二次心肌
Methods: 68 patients, 67 males and 1 females, with an average age of 57.9 years. 68 cases have a typical history, ECG changes and abnormal serum enzyme diagnosed as acute myocardial infarction. Of which acute penetrating infarction in 52 cases, acute subendocardial infarction in 16 cases. Myocardial scintigraphy was obtained by intravenous injection of technetium-stannous-pyrophosphate (20 mCi ~ (99m) ~ 2 hours after intravenous injection). Sixty-eight patients underwent myocardial infarction at 3.0 ± 1.1 days after the onset of symptoms of acute myocardial infarction. Nineteen patients before discharge from the hospital, 12.6 ± 2.8 days after infarction, performed a second myocardial
