摘要
目的 探讨急性心肌梗死（AMI）患者早期低钾血症的变化以及与心力衰竭的关系。方法收集200例急性心肌梗死的患者，发病时间小于24小时，所有患者均为首次入院。根据血钾浓度分为低钾血症组和正常血钾组，其中低钾血症组又分为重度低钾组（〈2．50mmol／L）、中度低钾组（2．51mmol／L-3．0mmool／L）和轻度低钾组（3．01-3．50mmol／L）。所有患者予以常规积极治疗，观察心力衰竭发生情况。结果AMI患者低钾血症的发生率为73．5％，低钾血症组心力衰竭的发生率为51．7％，明显高于正常组（22．6％），其中重度低钾组心衰的发生率78．2％，中度低钾组为58．3％，轻度低钾组为38．9％。结论急性心肌梗死早期易出现低钾血症，并且随着血钾浓度的降低，心力衰竭的发生率也明显增高。
Objective To discuss the relationship between acute myocardial infarction （AMI） patients with early changes of hypokalemia and heart failure. Methods 200 patients with acute myocardial infarction were enrolled, and all patients were first admitted to hospital with time of onset less than 24 hours. Based on serum potassium concentration all patients were divided into two groups, the normal group and the hypokalemia group which include severe hypokalemia（ 〈 2.50mmol/L）, moderate hypokalemia（2.51- 3.0retool/L）and mild hypokalemia （3.01 - 3.50mmol/L）. Routine treatment and observation of heart failure were tested for all patients. Results The occurrence of hypokalemia in patients with AMI was 73.5 %, and the occurrence of heart failure in hypokalemla group was 51.7 % which was higher than the normal group significantly（22.6 % ）. Among the hypokalemia group, heart failure rate were 78.2 % in severe hypokalemia, 58.3 % in moderate hypokalemia, 38.9% in mild hypokalemia. Conclusion Hypokalemia is easily occurred in AMI patients, and with decreasing of serum potassium concentra- tion, the incidence of heart failure was significantly increased.
