血清钾含量与急性心肌梗死患者梗塞部位的关系探讨

Investigation of relationship between serum potassium content and infarction location of patients with acute myocardial infarction

目的:观察急性心肌梗死(AMI)患者早期血清钾含量与梗塞部位的关系。方法:选取确诊AMI患者作为观察组,冠心病患者作为对照组,每组各100例。观察组患者发病入院立即采血;血清钾浓度低于3.5 mmol/L定为低血清钾,比较两组患者血清钾含量。结果:观察组患者早期血清钾含量明显低于对照组;前壁心梗血清钾显著低于下壁心梗和右室心梗。结论:急性心肌梗死患者早期血清钾含量低于未发生心肌梗死的冠心病患者,其梗塞好发部位依次为前壁、右室和下壁,AMI患者低血清钾易出现室性心率失常。

Objective： To study relationship between serum potassium content and location of infarction for acute myocardial infarction （AMI） patients. Methods： 100 patients with diagnosed AMI were selected as observation group and 100 patients with coro-nary heart diseases were chosen as control group. The serum potassium contents of the two groups were detected at admission immedi-ately and compared, and the serum potassium content of lower than 3. 5 mmol/ L were defined as low serum potassium. Results： The early serum potassium content of observation group was significantly lower than that of control group. The serum potassium content of the patient with anterior myocardial infarction was significantly lower than those of the patient with inferior myocardial infarction and right ventricular myocardial infarction. Conclusions： The serum potassium content of the patient with anterior myocardial infarction is significantly lower than those of the patients with coronary heart diseases but without myocardial infarction. The primary infarction sites are anterior wall, right ventricule and inferior wall. The low potassium content can lead to the occurrence of ventricular arrhythmia.
