摘　　要：目的:评价乳酸测定对心肌梗死预后的判断价值。方法:分析68例急性心肌梗死患者入院首次血乳酸与血气的测定结果。结果:患者血乳酸均值高于正常值且与治愈率有密切关系,乳酸浓度越高治愈率越低。血乳酸大于4mmol/L,存活率为12.5%;2～4mmol/L时存活率为30%;1～2mmol/L时为83.3%。治愈组与死亡组血乳酸比较差异有显著意义(P<0.05)。结论:血乳酸测定对心梗患者病情严重程度及预后评估是一项具有前瞻性意义的监测指标。Objective:To evaluate the role of blood lactic acid in the determination of prognosis in myocardial infarction patients. Methods:The first results of blood lactic acid and blood-gas after admission were analyzed in 68 acute myocardial infarction (AMI)patients. Results:The value of blood lactic acid in AMI patients was higher than normal one,and related to curative rate. The higher the lactic acid concentration was, the lower the curative rate was. When the lactic acid was greater than 4 mmol/L,2~4 mmol/L,and 1~2 mmol/L,the survival rate was 12.5% ,30.0% and 83.3% respectively. There was a significant difference in lactic acid concentration between curative and dead groups(P< 0.05). Conclusion: Blood lactic acid is a prospective marker for the evaluation of seriousness and prognosis in patients with AMI.
