心源性休克是急性心肌梗塞(AMI)病人死亡的最主要原因。本文对有关 AMI 病人外周血乳酸浓度升高先于休克的临床症状出现,以及血液乳酸可用作休克发生的预测指标之假设进行了检验。病人和方法研究对象为1988年11月到1989年7月收入冠心病护理病房治疗的291例连续性 AMI 病例,其中229例为研究组,另外62例用于交叉证实通过判别式函数分析所 Cardiogenic shock is the leading cause of death in patients with acute myocardial infarction (AMI). This article examines the hypothesis that elevated peripheral lactate concentrations in AMI patients precede the onset of shock and that blood lactate may be used as a predictor of shock. Patients and Methods Subjects: 291 consecutive AMI cases treated in a coronary care unit from November 1988 to July 1989, of whom 229 were in the study group and another 62 were used for cross-validation by discriminant function analysis
