Zinc concentrations in serum from 99 patients with acute myocardial infarction were correlated with the incidence of further complications and with activities in serum of the "cardiac" enzymes aspartate aminotransferase and lactate dehydrogenase. A significantly subnormal zinc concentration was observed for the patients, the lowest values being observed on the second and third days after infarct, particularly in patients with serious complications. Moreover, a linear correlation was observed between zinc values and enzyme activities until the fourth day after infarct. We conclude that measurement of zinc in the serum may have diagnostic value for acute myocardial infarction, although its prognostic value is still speculative.
对99例急性心肌梗死患者血清中的锌浓度与进一步并发症的发生率以及血清中“心脏”酶天冬氨酸氨基转移酶和乳酸脱氢酶的活性进行了相关性研究。观察到患者的锌浓度明显低于正常水平，最低值出现在梗死发生后的第二天和第三天，尤其是在有严重并发症的患者中。此外，在梗死发生后的第四天之前，锌值与酶活性之间存在线性相关性。我们得出结论，血清锌的测定可能对急性心肌梗死具有诊断价值，尽管其预后价值仍具有推测性。
