摘　　要：目的探讨钾离子水平对心肌梗死急性期预后的影响。方法将78例急性心肌梗死患者随机分为三组，正常血钾组、轻度升高组、明显升高组。观察三组患者急性期心律失常、休克、心力衰竭及死亡的发生率，比较其急性期预后的差异。结果心律失常、心力衰竭、休克以及死亡发生率在血钾明显升高组分别为68％、80％、60％、80％，其发生率显著高于正常血钾组（35．7％、10．7％、3．6％、3．6％）和轻度升高组（60％、32％、20％、28％），差异有统计学意义（P〈0．01）。结论心肌梗死急性期血钾浓度升高是出现严重并发症及死亡的重要参考指标，是反映心肌梗死急性期预后不良的独立危险因素。心肌梗死时应密切监测血清钾离子水平。Objective To investigate the effect of serum potassium level on prognosis in patients with myocardial infarction at acute stage. Methods Seventy-eight cases of acute myocardial infarction were randomly divided into three groups, normal serum potassium group, slight rising group and obviously rising group. The incidences of arrhythmia, shock, heart failure and death in the three groups were ob- served, and the prognosis differences at acute stage were compared. Results The incidences of arrhyth- mia, shock, heart failure and death in obviously rising group were 68% , 80% , 60% and 80% , which were obviously higher than those of the normal serum potassium group （ 35.7% , 10. 7% , 3.6% , 3.6% ） and the slight rising group（60%, 32%, 20%, 28% ）, the differences were significant （P 〈 0.01 ）. Conclusions Elevated serum potassium level in patients with myocardial infarction at acute stage is an important reference of serious eomplications and death, which is independent risk factor for bad prognosis in patients with myocardial infarction at acute stage. The serum potassium level should be closely monitored in patients with myocardial infarction.
