The serum levels and urinary excretion of magnesium and copper were studied in 66 patients with either acute myocardial ischemia or myocardial infarction. Serum for magnesium and copper determinations was obtained daily for three days. The initial serum magnesium levels were normal in patients with ischemia but were low in some patients with myocardial infarction. Patients developing ventricular arrhythmias with myocardial infarction showed the lowest levels of serum magnesium. Copper in the serum appeared elevated in patients developing acute congestive heart failure but the elevation was not statistically significant. These data indicate that a decrease in serum magnesium as evaluated may be associated with ventricular arrhythmias in patients with myocardial infarction; thus continued observations of magnesium levels in the myocardial infarction patient is warranted.
对66例急性心肌缺血或心肌梗死患者的血清镁和铜水平以及尿排泄情况进行了研究。连续三天每天采集血清用于测定镁和铜。缺血患者的初始血清镁水平正常，但部分心肌梗死患者的血清镁水平较低。发生心肌梗死并伴有室性心律失常的患者血清镁水平最低。发生急性充血性心力衰竭的患者血清铜水平似乎升高，但升高无统计学意义。这些数据表明，所评估的血清镁降低可能与心肌梗死患者的室性心律失常有关；因此，有必要对心肌梗死患者的镁水平进行持续观察。
