急性冠状动脉综合征血钾浓度测定及其意义

目的观察急性冠状动脉综合征患者的血钾浓度及其与预后的关系。方法将116例ACS患者分为AMI组56例和UAP组60例,分别在典型症状（胸闷、胸痛）发生6h内（治疗前）抽取静脉血测定血钾浓度。结果①AMI组血钾（3.78±0.46）mmol/L,UAP组血钾（4.33±0.42）mmol/L,两组比较,差异有极显著性（P〈0.001）。②AMI组的死亡率为14.3%,UAP组的死亡率为3.3%,两组死亡率比较也有显著性差异（P〈0.05）。结论AMI较UAP更易发生低钾血症,且预后不佳。

Serum potassium examining and its meaning in acute coronary syndrome

Objective To observe the serum potassium and its prognosis meaning in patients with acute coronary syndrome （ACS）. Methods 116 ACS cases were divided into acute myocardial infarction （AMI） group and unstable angina pectoris （UAP） group, the serum potassium were examined within 6 hours after onset of the typical symptom such as chest pain, chest tightness. Results （1）The serum potassium was （3.78±0.46）mmol/L in AMI group,（4.33±0.42）mmol/L in UAP group, there was significant difference between two groups（P〈0.001）.（2）The death rate was 14.3% in AMI group, and 3.3% in UAP group.There was significant difference between two groups （P〈0.05）. Conclusion Patients with AMI are liable to hypokalemia than those with UAP, and have poor prognosis.
