对急性心肌梗死(AMI)后的病人,应用多普勒超声检测左室舒张功能有助于评估预后,但多普勒变量易受多种因素的影响。左房容积较少受急性变化的影响,并可反映亚急性或慢性舒张功能,该文探讨左房容积在AMI病人预后危险评估中的作用。 方法 选择314例AMI病人作为研究对象。经超声对病人的左室收缩功能和舒张功能进行评估,测定左房容积并用体表面积进行校正。以左房容积指数32ml/m~2(大于正常2SD)为标准对病
In patients after acute myocardial infarction (AMI), the use of Doppler ultrasound to measure left ventricular diastolic function is helpful in assessing prognosis, but Doppler variables are susceptible to many factors. Left atrial volume less affected by acute changes, and can reflect subacute or chronic diastolic function, this article discusses the role of left atrial volume in the assessment of prognosis of AMI patients. Methods A total of 314 AMI patients were selected as the study subjects. The patient’s left ventricular systolic function and diastolic function were evaluated by ultrasonography, left atrial volume was measured and corrected with body surface area. To the left atrium volume index 32ml / m ~ 2 (greater than the normal 2SD) as the standard on the disease
