摘要
目的:研究β-受体阻滞剂对急性心肌梗死患者左心结构及心功能影响。方法:62例患者均于急性心肌梗死(AMI)后第1月末采用多普勒超声诊断仪检查,测量左心房(LA)、左心室舒张末内径(LVDD)、左心室后壁厚度(LVPWD)、左心室舒张末期室间隔厚度(IVSD),舒张早期峰值血流速度与舒张晚期峰值血流速度比(PFVE/PFVA),左室射血分数(LVEF)。结果:治疗组的LA、LV值较对照组小,PFVE/PFVA值较对照组大,均有显著性差异(P<0.05)。结论:β-受体阻滞剂对减轻AMI患者心脏重构及改善心脏舒张功能有一定作用。
Objective： To study the effect of β - receptor blocker on left ventricular structure and function in acute myocardial infarction （AMI）. Methods：62 patients with AMI underwent Doppler uhrasonography at the end of first month. The left atrium diameter （LA）, Left ventricular end diastolic diameter （LVDD）,left ventricular posterior wall depth （LVPWD）,left ventricular end diastolic interventricular septum depth （IVSD）, the ratio of PFVE to PFVA （PFVE/PFVA） and left ventricular ejection fraction （LVEF） were measured. Results： Compared with control group, the LA and LV were lower and PFVE/PFVA was higher in treatment group, showing significant differences （P 〈 0.05）. Conclusion：β - receptor blocker plays an role in reducing cardiac reconstitution and improve cardiac diastolic function in AMI patients.
