公认磷酸肌酸激酶(CPK)及乳酸脱氢酶(LDH)的同功酶CPK-MB、LDH_1、LDH_2检测系目前诊断急性心肌梗塞(AMI)的高特异性敏感指标。但发作症状至采血间隔及采血频率,与同功酶出现、峰值、持续及消退时间有关,迄今尚无明确规定。作者对66名临床症状及心电图确诊为AMI 者,首24小时每1～2小时,次24小时每4小时一次,第三个24小时每6小时采血一次,电泳法检测上述同功酶。并对其中获得 The CPK and LDH isozymes CPK-MB, LDH_1 and LDH_2 are widely recognized as high sensitivity and specificity indicators for the diagnosis of acute myocardial infarction (AMI). However, the onset of symptoms to blood sampling interval and the frequency of blood collection, with the emergence of the same enzyme, peak, duration and regression time, so far no clear rules. The authors of 66 clinical symptoms and ECG confirmed as AMI, the first 24 hours every 1 to 2 hours, every 24 hours once every 24 hours, the third 24 hours every 6 hours a blood collection, electrophoresis detection of the isozyme. And get it for it
