摘要
对80例因怀疑AMI收入CCU(冠心病监护室)的患者定期测定血清CK、乳酸脱氢酶(LDH)及LDH同功酶以研究LDH同功酶对诊断AMI的意义。认为LDH_1>LDH_2对诊断的意义稍小于CK升高。但LDH_1绝对值之峰值与CK峰值有较好的相关性(r=0.92)。由于LDH_1>LDH_2较CK升高历时久得多,故适用于检出就诊较晚的患者。若LDH_1>LDH_2持续超过2周,则心衰发生率及病死率均显著增高(P<0.01)。对估计预后有价值。
80 patients with suspected AMI admitted into the CCU were regularly measured for serum CK, LDH and LDH-isoenzymes to investigate the diagnostic significance of LDH-isoenzymes for AMI. LDH_1>LDH_2 was considered to slightly less significant than that of CK elevation, but there was close correlation between the peak absolute value of LDH_1 and that of CK(r=0.92). Since LDH_1> LDH_2 lasted muck longer than CK elevation, it is suitable to be used to detect patients with AMI who has delayed examination.When LDH_1> LDH_2 continued longer than 2 weeks, the morbility of heart failure and mortality may be increased markedly (P<0.01) and it is valuable to estimate the prognosis.
