急性心肌梗死患者梗死部位和冠状动脉病变与预后的关系

摘要：目的探讨急性心肌梗死合并低血钾患者梗死部位、冠状动脉病变及预后的关系。方法将212例急性心肌梗死患者发病后血钾水平分为两组：A组（低血钾组，血钾〈3．5mmol／L）；B组（血钾正常组，血钾3．5～5．5mmol／L）。将两组的梗死部位、并发症、预后及冠状动脉造影结果进行比较分析。结果急性心肌梗死患者低血钾者97例（占45．8％），梗死相关血管近端病变53例（占59．8％）、梗死相关血管为前降支的45例（占46．4％）、严重心律失常41例（占42．3％）、心力衰竭27例（占27．8％）梗死后心绞痛32（占33％），与血钾正常组分项比较差异显著（均为P〈O．05）。结论急性心肌梗死合并低血钾的梗死相关血管多为近端病变，梗死相关血管多为前降支，预后较差。

Clinical characteristics of 169 hand-foot-mouth disease cases complicated with encephalitis

Abstract：Objective To study the correlation of infarction sites in acute myocardial infarction with hypokalemia cases with prognosis. Methods The 212 patients with acute myocardial infarction were divided,based on potassium levels, into： group A （hypokalemia group, potassium 〈 3.5mmol/L） ; Normal group, group B （normal potassium potassium tendency for 3.5-5.5 retool/L）. The infarction sites,comphcations and prognosis of coronary angiography results of both groups were compated. Results Ninety-seven hypokalemia patients in acute myocardial infaredon group （45.8%）,53 cases withinfarction associated vascular proximal lesion were （59.8%）,anterior descending infarction related blood vessels for 45 （46.4%） ,severe arrhythmia cases of 41 （42.3%）,heart failure 27 cases（27.8%）,angina pectoris after infarction 32（33%）and significant difference compared with normal potassium （P〈0.05）. Conclusions Acute myocardial infarction complicated with hypokalemia is characterized by pmx/mal lesions of infarction-related blood vessels and most of the infarct/on-related vessels are anterior descending infarction with poor prognosis.r.
