作者为了探讨急性心肌梗塞早期血儿茶酚胺的动态及其临床意义,对26例发病在24小时内入院的急性心肌梗塞(AMI)病人进行了血中儿茶酚胺(CA)的测定。本组男22例,女4例,平均年龄66岁。其中前壁梗塞16例,下壁梗塞7例,非穿壁性梗塞3例。 CA的测定方法是,在发病后第一个12小时内每1～4小时采血,在此以后的24小时内每4～6小时采血。用高速液体层析法测定血CA,正常值为去甲肾上腺素(NAd)小于40～350pg/ml;肾上腺素(Ad)小于120pg/ml。
In order to investigate the dynamic changes and clinical significance of blood catecholamines in early stage of acute myocardial infarction, we measured blood levels of catecholamine (CA) in 26 patients with acute myocardial infarction (AMI) admitted within 24 hours. The group of 22 males and 4 females, with an average age of 66 years. Including anterior infarction in 16 cases, 7 cases of inferior wall infarction, non-penetrating infarction in 3 cases. CA is measured by taking blood every 1 to 4 hours in the first 12 hours after onset and every 4 to 6 hours in the next 24 hours. Plasma CA was measured by high performance liquid chromatography with normal values of norepinephrine (NAd) of less than 40-350 pg / ml and epinephrine (Ad) of less than 120 pg / ml.
