摘　　要：目的:探讨低血钾与急性心肌梗死的梗死部位及预后的关系。方法:106例患者根据心肌梗死早期血钾水平分为低血钾组、正常血钾组,对比两组的梗死部位及并发症的发生。结果:急性心肌梗死患者低血钾35例(33.0%),其中广泛前壁心肌梗死16例(45.7%),下壁10例(28.6%),故正常血钾组相比更容易合并低血钾(P<0.01)。低血钾组泵衰竭、心律失常、梗死后心绞痛、死亡等心脏事件明显高于正常血钾组(P均<0.05)。结论:急性心肌梗死合并低血钾预后相对较差。Objective：To discuss the relation between hypokalemia and the location and prognosis of acute myocardial infarction.Methods：A total of 106 cases were divided into hypokalemia group and normal group according to serum potassium at the early stage of myocardial infarction.The infarction sites and complication incidence were compared between the two groups.Results：There were 35 cases with hypokalemia（33.0%）,including 16 cases with extensive anterior myocardial infarction（45.7%）,and 10 cases with inferior myocardial infarction（28.6%）.Patients with normal serum potassium were more prone to have complication of hypokalemia（P0.01）.The incidences of pump failure,arrhythmia,postinfarction angina pectoris and death were higher in hypokalemia group（all P0.05）.Conclusions：Patients with acute myocardial infarction complicated with hypokalemia show worse prognosis.
